About this prospectus supplement

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of the notes that we are offering and other matters relating to us and our financial condition. The second part is the accompanying prospectus, which gives more general information about securities we may offer from time to time, some of which does not apply to the notes we are offering. Generally, when we refer to the prospectus, we are referring to both parts of this document combined. The description of the terms of the notes contained in this prospectus supplement supplements the description under the “Description of Debt Securities of RGA” in the accompanying prospectus, and to the extent it is inconsistent with that description, the information in this prospectus supplement replaces the information in the accompanying prospectus. If the description of the notes in the prospectus supplement differs from the description of the notes in the accompanying prospectus, you should rely on the information in this prospectus supplement.

When we use the terms “RGA,” “we,” “us” or “our” in this prospectus supplement, we mean Reinsurance Group of America, Incorporated and its subsidiaries, on a consolidated basis (but excluding the RGA Trusts), unless we state or the context implies otherwise, including, without limitation, with respect to descriptions of the notes or their terms or provisions (which are obligations of Reinsurance Group of America, Incorporated but not any of its subsidiaries). When we use the term “Variable Rate Junior Subordinated Debenture due 2065,” we mean the security initially known as our “6.75% Junior Subordinated Debentures due 2065” and initially issued in December 2005.

Unless we indicate otherwise, we base the information concerning our industry contained or incorporated by reference in this prospectus supplement or the accompanying prospectus on our general knowledge of and expectations concerning the industry. Our market position, market share and industry market size are based on our estimates using our internal data and estimates, based on data from various industry analyses, our internal research and adjustments and assumptions that we believe to be reasonable. We have not independently verified data from industry analyses and cannot guarantee their accuracy or completeness. In addition, we believe that data regarding the industry, market size and our market position and market share within such industry provide general guidance but are inherently imprecise. Further, our estimates and assumptions involve risks and uncertainties and are subject to change based on various factors, including those discussed in the “Risk factors” section of this prospectus supplement and the other information contained or incorporated by reference in this prospectus supplement or the accompanying prospectus. These and other factors could cause results to differ materially from those expressed in the estimates and assumptions.

You should rely only on the information contained in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference in this prospectus supplement or the accompanying prospectus and any written communication from us or the underwriters specifying the final terms of this offering. We have not, and the underwriters have not, authorized anyone to provide you with information that is different. This prospectus supplement and the accompanying prospectus may only be used where it is legal to sell the notes. The information in this prospectus supplement and the accompanying prospectus may only be accurate as of their respective dates and the information in the incorporated documents is only accurate as of their respective dates. Our business, financial condition, results of operations and prospects may have changed since those dates. The forward-looking statements included or incorporated by reference in this prospectus supplement or the accompanying prospectus are only made as of the date of this prospectus supplement or the accompanying prospectus or as of the date of such statement contained in the respective documents incorporated by reference in this prospectus supplement or the accompanying prospectus, respectively, and we disclaim any obligation to publicly update any forward-looking statement to reflect subsequent events or circumstances, unless we are obligated under the federal securities laws to update and disclose material developments related to previously disclosed information.

The distribution of this prospectus supplement and the accompanying prospectus and the offering of the notes in certain jurisdictions may be restricted by law. Persons who come into possession of this prospectus

S-ii

supplement and the accompanying prospectus should inform themselves about and observe any such restrictions. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which such offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to any person to whom it is unlawful to make such offer or solicitation.

Cautionary statement regarding forward-looking statements

This prospectus supplement and the documents incorporated by reference into this prospectus supplement or the accompanying prospectus contain both historical and forward-looking statements. Forward-looking statements are not based on historical facts, but rather reflect our current expectations, estimates and projections concerning future results and events. Forward-looking statements generally can be identified by the fact that they do not relate strictly to historical or current facts and include, without limitation, words such as “believe,” “expect,” “anticipate,” “may,” “could,” “intend,” “intent,” “belief,” “estimate,” “plan,” “foresee,” “likely,” “will” or other similar words or phrases. These forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties, assumptions and other factors that are difficult to predict and that may cause our actual results, performance or achievements to vary materially from what is expressed in or indicated by such forward-looking statements. We cannot make any assurance that projected results or events will be achieved.

The risk factors set forth in the sections entitled “Risk factors” in this prospectus supplement and the accompanying prospectus, and the matters discussed in RGA’s SEC filings, including (i) the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Annual Report”), and (ii) our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC after December 31, 2018, which reports are incorporated by reference herein, among others, could affect future results, causing these results to differ materially from those expressed in our forward-looking statements.

The forward-looking statements included and incorporated by reference in this prospectus supplement or the accompanying prospectus are only made as of the date of this prospectus supplement or the accompanying prospectus or the respective documents incorporated by reference, as applicable, and we disclaim any obligation to publicly update any forward-looking statement to reflect subsequent events or circumstances, unless we are obligated to do so under federal securities laws.

See “Risk factors” in this prospectus supplement and “Where You Can Find More Information” in the accompanying prospectus.

Risk factors

An investment in the notes involves certain risks. You should carefully consider the risk factors discussed under the heading “Cautionary statement regarding forward-looking statements” provided in this prospectus supplement beginning on page S-iii, the risks described under “Risk Factors” in our 2018 Annual Report, as well as the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business or financial performance. Our business, financial condition, or results of operations could be materially adversely affected by any of these risks. The market or trading price of the notes could decline due to any of these risks or other factors, and you may lose all or part of your investment.

In addition to the foregoing risks relating to us, the following are additional risks relating to an investment in the notes.

Risks related to ownership of the notes

The notes will be structurally subordinated to all obligations of our subsidiaries and neither we nor any of our subsidiaries are restricted pursuant to the indenture from incurring additional debt or other liabilities in the future.

The notes will not be guaranteed by our subsidiaries, and therefore they will be structurally subordinated to all existing and future indebtedness and other liabilities and commitments of our subsidiaries, including claims under reinsurance contracts, debt obligations and other liabilities incurred in the ordinary course of business. As of March 31, 2019, our consolidated short- and long-term debt, net of $18.2 million unamortized issuance costs, aggregated approximately $2,787.7 million, which consisted of:

Such short- and long-term debt also includes $88.4 million of borrowings outstanding under the 4.09% promissory note due 2039 issued by our subsidiary, Gateway Ridge LLC, which will rank structurally senior to the notes.

Additionally, our other subsidiaries had approximately $52.9 billion of outstanding liabilities reflected in our financial statements, which includes $363.3 million of liabilities associated with the floating rate insured notes issued by Timberlake Financial, $123.2 million of liabilities associated with the collateral financing obtained by RGA Barbados and $172.8 million of liabilities associated with the asset-backed notes issued by Chesterfield Financial, all of which will rank structurally senior to the notes. For more information, see “Capitalization,” below, as well as “Schedule II-Condensed Financial Information of the Registrant” and Notes 13 and 14 to the consolidated financial statements in our 2018 Annual Report, which are incorporated by reference herein.

In addition, the indenture for the notes will not prohibit or limit us or any of our subsidiaries from incurring any indebtedness or other obligations. In the event of the insolvency, liquidation, reorganization, dissolution or other winding up of a subsidiary, including an insurance company subsidiary, all creditors of that subsidiary would be entitled to payment in full out of the assets of such subsidiary before we, as shareholder, would be

S-4

entitled to any payment. Following payment by the subsidiary of its liabilities, the subsidiary may not have sufficient assets to make payments to us to allow us to make payments on the notes and our other debt. See “—RGA is an insurance holding company, and payments on the notes will only be made from our earnings and assets, and not those of our subsidiaries.” Furthermore, if we incur additional debt or liabilities, our ability to pay our obligations on the notes could be adversely affected. We expect that we will from time to time incur additional debt and other liabilities. We are also not restricted from paying dividends or issuing or repurchasing our securities under the indenture.

RGA is an insurance holding company, and payments on the notes will only be made from our earnings and assets, and not those of our subsidiaries.

RGA is an insurance holding company, with our principal assets consisting of the stock of our reinsurance company subsidiaries, and substantially all of our income is derived from those subsidiaries. The notes will be solely our obligations, and our subsidiaries will have no obligation to pay any amount in respect of the notes or to make any funds available for any such payment. Accordingly, we will be dependent on assets held, dividends and other distributions or loans from our subsidiaries, loans from third parties or new capital raising transactions to generate the funds necessary to meet obligations with respect to the notes, including the payment of principal and interest, and if these sources are not adequate, we may be unable to make payments of principal or interest in respect of the notes.

Our ability to pay principal and interest on any debt securities, including the notes, is limited and depends in part on the ability of our insurance company subsidiaries, our principal sources of cash flow, to declare and distribute dividends or to advance money to us in the form of intercompany loans, other payments, loans from third parties or new capital raising transactions. Our insurance company subsidiaries are subject to various statutory and regulatory restrictions, applicable to insurance companies generally, that limit the amount of cash dividends, loans and advances that those subsidiaries may pay to us. For fiscal year 2019, the amount of dividends that may be paid to us by RGA Reinsurance Company, our largest operating subsidiary, without prior approval from Missouri insurance regulators is equal to the greater of (i) the prior year’s statutory net gain from operations, or approximately $654 million, and (ii) 10% of the prior year-end statutory capital and surplus, or approximately $208 million. However, due to risk based capital considerations, RGA Reinsurance Company is unlikely to pay to us an amount of dividends in excess of $208 million. We cannot assure you that more stringent dividend restrictions will not be adopted, as discussed in our 2018 Annual Report under “Risk Factors—Risks related to our business—Our reinsurance subsidiaries are highly regulated, and changes in these regulations could negatively affect our business.” Covenants contained in some of our existing and future debt agreements and regulations relating to capital requirements affecting some of our most significant subsidiaries may also restrict the ability of certain subsidiaries to pay dividends and other distributions and make loans to us.

As a result of our insurance holding company structure, in the event of the insolvency, liquidation, reorganization, dissolution or other winding-up of one of our reinsurance subsidiaries, all creditors of that subsidiary would be entitled to payment in full out of the assets of such subsidiary before we, as shareholder, would be entitled to any payment. Our subsidiaries would have to pay their direct creditors in full before our creditors, including holders of any class of common stock, preferred stock or debt securities of RGA, could receive any payment from the assets of such subsidiaries.

Failure to comply with restrictive covenants contained in the indenture governing the notes or agreements governing any other existing or future indebtedness could trigger prepayment obligations, which could adversely affect our and our subsidiaries’ business, financial condition and results of operations.

The indenture governing the notes contains covenants that impose restrictions on us with respect to, among other things, the incurrence of liens on, and the disposition of, the capital stock of certain of our subsidiaries. In addition, the indenture governing the notes requires us to file with the trustee copies of annual, quarterly and current reports which we are required to file with the Securities and Exchange Commission. We and certain of

S-5

our subsidiaries are also required to comply with certain covenants set forth in our existing credit facilities and in other existing financing agreements and any debt agreements we and our subsidiaries may enter into in the future. Failure to comply with any of such covenants could result in an event of default under the applicable agreements governing such indebtedness, which could, if not cured or waived, result in us or certain of our subsidiaries being required to repay such indebtedness. As a result, we and our subsidiaries’ business, financial condition, results of operations and liquidity could be adversely affected.

We may redeem the notes prior to the maturity date, and you may not be able to reinvest in a comparable security.

We have the option to redeem the notes for cash, in whole or in part, at any time at the redemption price set forth under “Description of the notes—Optional redemption” in this prospectus supplement. If we choose to redeem your notes, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the notes.

An active trading market for the notes may not develop or be sustained.

The notes are new securities for which there currently is no market. We have not applied for and do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any automated dealer quotation system. Although the underwriters have advised us that they currently intend to make a market in the notes after completion of the offering, they have no obligation to do so, and such market making activities may be discontinued at any time and without notice. We cannot assure you that any market for the notes will develop or be sustained, that holders of the notes will be able to sell their notes or that holders of the notes will be able to sell their notes at favorable prices.

An increase in interest rates could cause a decrease in the market price of the notes.

A variety of factors may influence the price of the notes in public trading markets. We believe that investors generally perceive companies engaged in the reinsurance business as yield-driven investments and compare the annual yield from distributions by such companies with yields on various other types of financial instruments. In general, as market interest rates rise, notes bearing interest at a fixed rate generally decline in value because the premium, if any, over market interest rates will decline. Thus, an increase in market interest rates generally could adversely affect the market price of the notes. We cannot predict the future level of market interest rates.

Our credit ratings may not reflect all risks of an investment in the notes, and downgrades or other changes in our credit ratings could affect our financial results and reduce the market value of the notes.

Our credit ratings are an assessment of our ability to pay our obligations. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the rating organization in its sole discretion. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the notes. Our credit ratings, however, may not reflect the potential impact of risks related to the structure of the notes or market or other factors discussed in this prospectus supplement on the value of the notes. Neither us nor any underwriter has any obligation to the holders of the notes to maintain any credit ratings or to advise holders of the notes of any change in its credit ratings and there is no requirement in the indenture governing the notes to maintain a rating on the notes. Each agency’s rating should be evaluated independently of any other agency’s rating.

Additionally, the credit ratings assigned to our unsecured indebtedness, including the notes upon issuance, may affect our ability to obtain new financing and the costs of our financing. It is possible that rating agencies may downgrade our credit ratings or change their outlook about us, which could increase our cost of capital and make our efforts to raise capital more difficult and, in turn, adversely affect our financial results. Such a downgrade in rating may also reduce the price that a subsequent purchaser may be willing to pay for the notes.

S-6

The indenture governing the notes does not prohibit certain transactions involving RGA or its subsidiaries.

Except as described under “Description of the notes—Covenants of RGA—Limitations on Issuance or Disposition of Stock of Restricted Subsidiaries” and under “Description of the notes—Covenants of RGA—Limitation on Consolidation, Merger, Conveyance, Sale of Assets and Other Transfers” in this prospectus supplement, the indenture does not contain any provisions that would afford holders of the notes protection in the event of (i) a change of control, (ii) a reorganization, restructuring, merger, amalgamation, consolidation or similar transaction that may adversely affect the holders of the notes or (iii) other indebtedness incurred by RGA or its subsidiaries. Transactions such as the sale of all or substantially all of our assets or the merger, amalgamation or consolidation with another entity may increase the amount of our respective indebtedness or substantially reduce or eliminate our respective assets, which may have an adverse effect on our ability to service our indebtedness, including the notes. The indenture governing the notes does not require us to offer to purchase the notes in connection with a change of control or require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth. Furthermore, there are no financial covenants in the indenture that prohibit RGA or its subsidiaries from incurring additional indebtedness.

S-7

Use of proceeds

We estimate that the net proceeds from the sale of the notes will be approximately $593.8 million, after deducting the underwriting discounts and estimated offering expenses payable by us. We anticipate that we will use the net proceeds from the offering of the notes to repay upon maturity our $400 million 6.45% senior notes that mature on November 15, 2019, and the remainder for general corporate purposes.

Pending the use of the net proceeds from the offering, we intend to invest the net proceeds in interest-bearing short-term investments and investment-grade securities.

S-8

Capitalization

We present in the table below the capitalization of RGA and its subsidiaries:

You should read this table in conjunction with our consolidated financial statements, the notes relating to them and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” which are contained in our 2018 Annual Report and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2019, each of which is incorporated by reference herein.

Selected consolidated financial and operating data

We present in the table below our selected consolidated financial data and other data which should be read in conjunction with and is qualified in its entirety by reference to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and unaudited consolidated financial statements and the related notes which are contained in our 2018 Annual Report and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2019, each of which is incorporated by reference herein. The selected consolidated financial data for the fiscal years ended December 31, 2014, 2015, 2016, 2017 and 2018 have been derived from our financial statements which have been audited by Deloitte & Touche LLP, an independent registered public accounting firm. The selected consolidated financial data for the three months ended March 31, 2018 and 2019 have been derived from our unaudited consolidated financial statements. In the opinion of our management, the unaudited information reflects all adjustments (consisting only of normal and recurring adjustments) necessary for a fair presentation of the results for those periods. Results for the three months ended March 31, 2018 and 2019 are not necessarily indicative of the results to be expected for the full fiscal year.

S-11

Description of the notes

The following description is a summary of the terms of the notes. The descriptions in this prospectus supplement and the accompanying prospectus contain descriptions of certain terms of the notes and the related indenture but do not purport to be complete, and reference is hereby made to the indenture, dated as of August 21, 2012, between us and The Bank of New York Mellon Trust Company, N.A., as trustee, which has been filed as an exhibit to the Current Report on Form 8-K filed on August 21, 2012 and incorporated by reference in the registration statement of which this prospectus supplement and the accompanying prospectus are a part, and to the Trust Indenture Act of 1939, as amended, and to a supplemental indenture with respect to the notes, which we will file as an exhibit to a Current Report on Form 8-K and which will be incorporated by reference in the registration statement of which this prospectus supplement and the accompanying prospectus are a part. You may also request copies of the indenture and the supplemental indenture with respect to the notes from us at our address set forth under “Where You Can Find More Information” in the accompanying prospectus. This summary supplements the description of the debt securities in the accompanying prospectus and, to the extent it is inconsistent, replaces the description in the accompanying prospectus. References to “we,” “us” and “our” in the following description refers only to Reinsurance Group of America, Incorporated and not to any of its subsidiaries.

General

We will issue the notes under the indenture, dated as of August 21, 2012, as amended and supplemented by a supplemental indenture to be dated as of the date of issuance of the notes, in each case, between us and The Bank of New York Mellon Trust Company, N.A., as trustee, which we refer to collectively as the “indenture.”

We will initially issue $600 million aggregate principal amount of the notes. The notes will mature on May 15, 2029 (or if such day is not a business day, the following business day).

Interest on the notes will accrue at the rate of 3.900% per year and will be payable semiannually in arrears on May 15 and November 15 of each year, commencing November 15, 2019. Interest on the notes will accrue from their issue date, or if interest has already been paid, from the date it was most recently paid. We will make each interest payment on the notes to the holders of record on the immediately preceding May 1 and November 1. Interest on the notes will be computed on the basis of a 360-day year of twelve 30-day months. Principal of and interest on the notes will be payable, and the notes will be exchangeable and transfers thereof will be registrable, at the corporate trust office or agency of The Bank of New York Mellon Trust Company, N.A. located at 2 North LaSalle, Suite 700, Chicago, Illinois 60602.

The notes will be issued only in registered form, without coupons and in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes may be transferred or exchanged without service charges, other than any tax or other governmental charge imposed in connection with such transfer or exchange. We have initially appointed The Bank of New York Mellon Trust Company, N.A., as the registrar and paying agent for the notes.

We may from time to time, without the consent of the existing holders, create and issue further notes having the same terms and conditions as the notes being offered hereby in all respects, except for issue date, public offering price and, if applicable, the first payment of interest thereon; provided that if any such additional notes are not fungible with the notes offered hereby for U.S. federal income tax purposes, such additional notes will have one or more separate CUSIP numbers from the notes. Any additional notes having such similar terms, together with the notes offered hereby, will constitute a single series of securities under the indenture, including for purposes of voting.

Ranking

The notes:

S-12

The indenture will not preclude our subsidiaries from issuing secured or unsecured indebtedness. If RGA issues secured indebtedness, to the extent the security granted consists of voting stock in restricted subsidiaries, the indenture will require the notes to rank equally as to security. However, to the extent the security consists of other assets, the indenture will not provide corresponding protection for the notes. The notes will not be obligations of or guaranteed by any of our subsidiaries. Therefore, indebtedness or preferred stock held by third parties issued by our subsidiaries or indebtedness issued by us secured by assets other than voting stock of restricted subsidiaries may be paid ahead of the notes in the event of our or our subsidiaries’ insolvency.

Because RGA is an insurance holding company, its principal assets consist of the stock of its insurance company subsidiaries, and, absent any additional capital raising or borrowing, its principal cash flow would be derived from dividends and other distributions or loans from its insurance company subsidiaries or new capital raising transactions. Therefore, RGA may rely primarily on dividends or other payments from its operating subsidiaries to pay principal and interest on its outstanding debt obligations, including the notes. The principal source of funds from these operating subsidiaries comes from their current operations. RGA can also utilize loans from third parties, cash, cash equivalents and investment securities maintained in its portfolio for these payments. In addition, regulatory and other legal restrictions may limit the amount of dividends and other payments its subsidiaries can make to it.

Our insurance company subsidiaries are subject to various state statutory and regulatory restrictions, applicable to insurance companies generally, that limit the amount of cash dividends, loans and advances that those subsidiaries may pay to us. See “Business—Corporate Structure,” “—Regulation” and “—Restrictions on Dividends and Distributions” in our 2018 Annual Report, which is incorporated by reference herein, and “Risk Factors—Risks related to ownership of the notes—RGA is an insurance holding company, and payments on the notes will only be made from our earnings and assets, and not those of our subsidiaries” in this prospectus supplement.

As a result of RGA being an insurance holding company, the notes will be structurally subordinated to all indebtedness and other liabilities and commitments of RGA’s subsidiaries’ existing and future obligations, including claims under reinsurance contracts, debt obligations and other liabilities incurred in the ordinary course of business. RGA only has a shareholder’s claim in the assets of its subsidiaries. This shareholder’s claim is junior to claims that creditors or holders of preferred stock of RGA’s subsidiaries have against those subsidiaries. Holders of the notes will only be creditors of RGA, and such holders will not be creditors of RGA’s subsidiaries, where most of RGA’s consolidated assets are located. As of March 31, 2019, our consolidated short- and long-term debt, net of $18.2 million unamortized issuance costs, aggregated approximately $2,787.7 million, which consisted of:

S-13

Such short- and long-term debt also includes $88.4 million of borrowings outstanding under the 4.09% promissory note due 2039 issued by our subsidiary, Gateway Ridge LLC, which will rank structurally senior to the notes.

Additionally, our other subsidiaries had approximately $52.9 billion of outstanding liabilities reflected in our financial statements, which includes $363.3 million of liabilities associated with the floating rate insured notes issued by Timberlake Financial, $123.2 million of liabilities associated with the collateral financing obtained by RGA Barbados and $172.8 million of liabilities associated with the asset-backed notes issued by Chesterfield Financial, all of which will rank structurally senior to the notes. For more information, see “Capitalization,” above, as well as “Schedule II-Condensed Financial Information of the Registrant” and Notes 13 and 14 to the consolidated financial statements in our 2018 Annual Report, which are incorporated by reference herein. Also, see “Business—Regulation—Default or Liquidation” in our 2018 Annual Report, which is incorporated by reference herein and “Risk factors—Risks related to ownership of the notes—The notes will be structurally subordinated to all obligations of our subsidiaries and neither we nor any of our subsidiaries are restricted from incurring additional debt or other liabilities in the future”, and “—RGA is an insurance holding company, and payments on the notes will only be made from our earnings and assets, and not those of our subsidiaries” in this prospectus supplement.

Optional redemption

The notes will be redeemable, in whole or in part, at our option at any time or from time to time (the date of any such redemption, a “Redemption Date”), as set forth below. If the notes are redeemed prior to February 15, 2029 (the date which is three months prior to final maturity of the notes), the redemption price will be equal to the greater of:

plus, in each case, accrued and unpaid interest to, but excluding, the relevant Redemption Date.

If the notes are redeemed on or after February 15, 2029 (the date which is three months prior to final maturity of the notes), the redemption price will be equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the relevant Redemption Date.

“Adjusted Treasury Rate” means, with respect to any date of redemption, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that date of redemption.

“Comparable Treasury Issue” means the U.S. Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the notes to be redeemed (assuming, for this purpose, that such notes mature on February 15, 2029 (the date which is three months prior to final maturity of the notes)) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of those notes (assuming, for this purpose, that such notes mature on February 15, 2029 (the date which is three months prior to final maturity of the notes)).

S-14

“Comparable Treasury Price” means, with respect to any date of redemption, (i) the average of the Reference Treasury Dealer Quotations for the date of redemption, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than three Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Quotation Agent” means one of the Reference Treasury Dealers appointed by us.

“Reference Treasury Dealer” means (i) J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets, LLC and Wells Fargo Securities, LLC, and, in each case, their respective successors or their respective affiliates that are Primary Treasury Dealers; provided, however, that if any of them shall cease to be a Primary Treasury Dealer, we shall substitute therefor another nationally recognized investment banking firm that is a primary U.S. Government securities dealer in the U.S. (a “Primary Treasury Dealer”), and (ii) one other Primary Treasury Dealer selected by us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any date of redemption, the average, as determined by the Quotation Agent, after consultation with us, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding that date of redemption.

Notice of any redemption will be delivered at least 30 days but not more than 60 days before the date of redemption to each holder of the notes to be redeemed. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the notes or portions thereof called for redemption. If less than all of the notes are to be redeemed, the notes shall be selected by the trustee by lot or such other method as the trustee shall deem fair and appropriate, provided that, so long as the notes are in the form of global notes, such selection shall be made by The Depository Trust Company (“DTC”) in accordance with its applicable procedures, and provided further that the unredeemed portion of the principal amount of any note shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such note.

Sinking fund

There will be no sinking fund for the notes.

Covenants of RGA

The indenture will not contain any provisions which will restrict us from incurring, assuming or becoming liable with respect to any indebtedness or other obligations, whether secured or unsecured, or from paying dividends or making other distributions on our capital stock or purchasing or redeeming our capital stock. The indenture also will not contain any financial ratios or specified levels of net worth or liquidity to which we must adhere. In addition, the indenture will not contain any provision which would require that we repurchase or redeem or otherwise modify the terms of any of the notes upon a change in control or other events involving RGA which may adversely affect the creditworthiness of the notes.

The indenture will contain, among others, the following covenants, which use some defined terms, whose meanings we provide below. As is the case in the covenants relating to our 6.45% Senior Notes due 2019, our 5.00% Senior Notes due 2021, our 4.70% Senior Notes due 2023 and our 3.95% Senior Notes due 2026, the definition of “Subsidiary” that will be contained in the indenture for the notes will not include any corporation (a “Special Reserve Subsidiary”) established in connection with a transaction structured to satisfy the regulatory or operational reserve requirements of another Subsidiary that is an insurance company. As a result, holders of the notes will not have the benefit of the covenants summarized below to the extent such a Special Reserve Subsidiary would otherwise be covered and limited by these covenants.

S-15

Limitations on Liens

We will not, and will not permit any Subsidiary to, incur, issue, assume or guaranty any indebtedness if such indebtedness is secured by a mortgage, pledge of, lien on, security interest in or other encumbrance upon any shares of Voting Stock of any Restricted Subsidiary, whether that Voting Stock is now owned or is hereafter acquired, without providing that the notes (together with, if we shall so determine, any other indebtedness or obligations of RGA or any Subsidiary ranking equally with the notes and then existing or thereafter created) shall be secured equally and ratably with, or prior to, that indebtedness. The indenture excepts from this limitation secured debt which we or our Subsidiaries may incur, issue, assume, guarantee or permit to exist up to 10% of the value of our Consolidated Tangible Net Worth.

The foregoing limitation on liens will not apply to:

(1) indebtedness secured by a pledge of, lien on or security interest in any shares of Voting Stock of any corporation if such pledge, lien or security interest is made or granted prior to or at the time such corporation becomes a Restricted Subsidiary; provided that such pledge, lien or security interest was not created in anticipation of the transfer of such shares of Voting Stock to us or our Subsidiaries;

(2) liens or security interests securing indebtedness of a Restricted Subsidiary to us or another Restricted Subsidiary; or

(3) the extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any lien or security interest referred to in the foregoing clauses (1) and (2) but only if the principal amount of indebtedness secured by the liens or security interests immediately prior thereto is not increased and the lien or security interest is not extended to other property.

Limitations on Issuance or Disposition of Stock of Restricted Subsidiaries

We will not, nor will we permit any Restricted Subsidiary to, issue, sell, assign, transfer or otherwise dispose of any shares of capital stock (other than non-voting preferred stock) of any Restricted Subsidiary (or of any Subsidiary having direct or indirect control of any Restricted Subsidiary), except, subject to the covenant relating to “Limitation on Consolidation, Merger, Conveyance, Sale of Assets and Other Transfers” discussed below, for:

(1) director’s qualifying shares;

(2) a sale, assignment, transfer or other disposition of any capital stock of any Restricted Subsidiary (or of any Subsidiary having direct or indirect control of any Restricted Subsidiary) to us or to one or more Restricted Subsidiaries;

(3) a sale, assignment, transfer or other disposition of all or part of the capital stock of any Restricted Subsidiary (or of any Subsidiary having direct or indirect control of any Restricted Subsidiary) for consideration which is at least equal to the fair value of such capital stock as determined by our board of directors acting in good faith;

(4) the issuance, sale, assignment, transfer or other disposition made in compliance with an order of a court or regulatory authority of competent jurisdiction, other than an order issued at the request of RGA or any Restricted Subsidiary; or

(5) issuance for consideration which is at least equal to fair value as determined by our board of directors acting in good faith.

Limitation on Consolidation, Merger, Conveyance, Sale of Assets and Other Transfers

We will not consolidate with or merge with or into or wind up into, whether or not we are the surviving corporation, or sell, assign, convey, transfer or lease our properties and assets substantially as an entirety to any person, unless:

(1) the surviving corporation or other person is organized and existing under the laws of the U.S. or one of the 50 states, any U.S. territory or the District of Columbia;

S-16

(2) the surviving corporation or other person assumes the obligation to pay the principal of, and premium, if any, and interest on the notes, and to perform or observe all covenants under the indenture; and

(3) immediately after the transaction, there is no event of default under the indenture.

Upon the consolidation, merger or sale, the successor corporation formed by the consolidation, or into which we are merged or to which the sale is made, will succeed to, and be substituted for us under the indenture.

No quantitative or other established meaning has been given to the phrase “substantially as an entirety” by courts that have interpreted this phrase in various contexts. In interpreting this phrase, courts, among other things, make a subjective determination as to the portion of assets conveyed, considering such factors as the value of assets conveyed, the proportion of an entity’s income derived from the assets conveyed and the significance of those assets to the ongoing business of the entity. Due to that uncertainty, it may be difficult for holders of the notes to ascertain whether a viable claim exists under the indenture with respect to any given transaction.

We will not be required pursuant to the indenture to repurchase the notes, in whole or in part, with the proceeds of any sale, transfer or other disposition of any shares of capital stock of any Restricted Subsidiary (or of any Subsidiary having direct or indirect control of any Restricted Subsidiary). Furthermore, the indenture will not provide for any restrictions on our use of any such proceeds.

Certain definitions

We provide below certain defined terms which are used in the covenants above and which will be used in the indenture. You should refer to the indenture for a full disclosure of all of these terms.

“Consolidated Tangible Net Worth” means the total shareholders’ equity appearing on RGA’s most recent publicly filed consolidated balance sheet prepared in accordance with generally accepted accounting principles less intangible assets such as goodwill, trademarks, tradenames, patents and unamortized debt discount and expense.

“Restricted Subsidiary” means:

(1) any Significant Subsidiary of RGA existing on the date of the indenture;

(2) any Subsidiary of RGA, organized or acquired after the date of the indenture which is a Significant Subsidiary; and

(3) an Unrestricted Subsidiary which is reclassified as a Restricted Subsidiary by a resolution adopted by the board of directors of RGA.

“Significant Subsidiary” means a Subsidiary, including its direct and indirect Subsidiaries, which meets any of the following conditions (in each case determined in accordance with generally accepted accounting principles):

(1) RGA’s and its other Subsidiaries’ investment in and advances to the Subsidiary exceed 10% of the total assets of RGA and its Subsidiaries consolidated as of the end of the most recently completed fiscal year;

(2) RGA’s and its other Subsidiaries’ proportionate share of the total assets, after inter-company eliminations, of the Subsidiary exceeds 10% of the total assets of RGA and its Subsidiaries consolidated as of the end of the most recently completed fiscal year; or

(3) RGA’s and its other Subsidiaries’ equity interest in the income from continuing operations before income taxes, extraordinary items and cumulative effect of a change in accounting principles of the Subsidiary exceeds 10% of such income of RGA and its Subsidiaries consolidated for the most recently completed fiscal year.

S-17

“Subsidiary” means (1) any corporation of which at least a majority of the outstanding stock having by the terms thereof ordinary voting power for the election of directors of such corporation (irrespective of whether or not at the time stock of any other class or classes of such corporation shall have or might have voting power by reason of the happening of any contingency) is at the time directly or indirectly owned by RGA or one or more other Subsidiaries and (2) any other person in which RGA or one or more other Subsidiaries, directly or indirectly, at the date of determination, (x) own at least a majority of the outstanding ownership interests or (y) have the power to elect or direct the election of, or to appoint or approve the appointment of, at least the majority of the directors, trustees or managing members of, or other persons holding similar positions with, such person); provided, however, that Subsidiary shall not include such a person established in connection with a transaction structured to satisfy the regulatory or operational reserve requirements of another Subsidiary that is an insurance company.

“Unrestricted Subsidiary” means any Subsidiary which is not a Restricted Subsidiary.

“Voting Stock” means capital stock, the holders of which have general voting power under ordinary circumstances to elect at least a majority of the board of directors of a corporation, provided that, for the purposes of this definition, capital stock which by a resolution adopted by the board of directors of RGA carries only the right to vote conditioned on the happening of an event shall not be considered voting stock whether or not such event shall have happened.

Events of default

The event of default provisions of the indenture will apply to the notes. You should refer to the description of the events of defaults and the related remedies of the holders of notes and the trustee under “Description of Debt Securities of RGA—Events of Default” in the accompanying prospectus.

The notes will also provide that an acceleration of the maturity of any indebtedness of RGA or any Subsidiary, in an aggregate principal amount in excess of $175,000,000, if such failure to pay is not discharged or such acceleration is not annulled within 15 days after due notice, will constitute an event of default with respect to the notes.

The cross-acceleration provision summarized above is triggered by a threshold amount of $175,000,000. This amount is higher than the threshold amounts of $120,000,000 contained in the comparable cross-acceleration provisions relating to our 3.95% Senior Notes due 2026 and $100,000,000 contained in the comparable cross-acceleration provisions relating to our 6.45% Senior Notes due 2019, our 5.00% Senior Notes due 2021 and our 4.70% Senior Notes due 2023. As a result, holders of the notes may not have a cross-acceleration right and remedy when holders of our other senior notes do. In addition, the terms of our 6.45% Senior Notes due 2019 provide that the failure to pay certain amounts of indebtedness constitutes an event of default. The terms of the notes, like our 5.00% Senior Notes due 2021, our 4.70% Senior Notes due 2023 and our 3.95% Senior Notes due 2026, will not contain a comparable event of default. As of the date of this prospectus supplement, approximately $400,000,000 in aggregate principal was outstanding on our 6.45% Senior Notes due 2019, approximately $400,000,000 in aggregate principal was outstanding on our 5.00% Senior Notes due 2021, approximately $400,000,000 in aggregate principal was outstanding on our 4.70% Senior Notes due 2023 and approximately $400,000,000 in aggregate principal was outstanding on our 3.95% Senior Notes due 2026.

Defeasance

The provisions of the indenture relating to defeasance, satisfaction or discharge, which are described under the caption “Description of Debt Securities of RGA—Defeasance; Satisfaction and Discharge” in the accompanying prospectus, will apply to the notes.

Governing law

The indenture and the notes will be governed by, and construed in accordance with, the laws of the State of New York.

S-18

Book-entry; Delivery and form

The notes will be represented by one or more global notes (the “global notes”) that will be deposited with and registered in the name of DTC or its nominee for the accounts of its participants, including Euroclear Bank S.A./N.V., or Euroclear, as operator of the Euroclear System, and Clearstream Banking, société anonyme, or Clearstream. We will not issue certificated notes, except in the limited circumstances described below. Transfers of ownership interests in the global notes will be effected only through entries made on the books of DTC participants acting on behalf of beneficial owners. You, as the beneficial owner of notes, will not receive certificates representing ownership interests in the global notes, except in the event that use of the book-entry system for the notes is discontinued. You will not receive written confirmation from DTC of your purchase. The direct or indirect participants through whom you purchased the notes should send you written confirmations providing details of your transactions, as well as periodic statements of your holdings. The direct and indirect participants are responsible for keeping accurate account of the holdings of their customers like you. The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to own, transfer or pledge beneficial interests in the global notes.

So long as DTC or its nominee is the registered owner and holder of the global notes, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by the global notes for all purposes under the indenture relating to the notes. Except as provided below, you, as the beneficial owner of interests in the global notes, will not be entitled to have notes registered in your name, will not receive or be entitled to receive physical delivery of notes in definitive form and will not be considered the owner or holder thereof under the indenture. Accordingly, you, as the beneficial owner, must rely on the procedures of DTC and, if you are not a DTC participant, on the procedures of the DTC participants through which you own your interest, to exercise any rights of a holder under the indenture.

Neither we, the trustee, nor any other agent of ours or agent of the trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in global notes or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests. DTC’s practice is to credit the accounts of DTC’s direct participants with payment in amounts proportionate to their respective holdings in principal amount of beneficial interest in a security as shown on the records of DTC, unless DTC has reason to believe that it will not receive payment on the payment date. The underwriters will initially designate the accounts to be credited. Beneficial owners may experience delays in receiving distributions on their notes because distributions will initially be made to DTC and they must be transferred through the chain of intermediaries to the beneficial owner’s account. Payments by DTC participants to you will be the responsibility of the DTC participant and not of DTC, the trustee or us. Accordingly, we and any paying agent will have no responsibility or liability for any aspect of DTC’s records relating to, or payments made on account of, beneficial ownership interests in notes represented by a global securities certificate; any other aspect of the relationship between DTC and its participants or the relationship between those participants and the owners of beneficial interests in a global securities certificate held through those participants; or the maintenance, supervision or review of any of DTC’s records relating to those beneficial ownership interests.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

We have been informed that, under DTC’s existing practices, if we request any action of holders of the notes, or an owner of a beneficial interest in a global security such as you desires to take any action which a holder of notes is entitled to take under the indenture, DTC would authorize the direct participants holding the relevant beneficial interests to take such action, and those direct participants and any indirect participants would authorize beneficial owners owning through those direct and indirect participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

S-19

DTC, Clearstream and Euroclear have provided us with the following information and neither we nor the underwriters take any responsibility for its accuracy:

DTC

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

DTC also facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between participants’ accounts. This eliminates the need for physical movement of securities certificates. Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.

Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Clearstream

Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream participants include underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Clearstream’s U.S. participants are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream participant either directly or indirectly.

Distributions with respect to notes held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

Euroclear

Euroclear was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear performs various other services, including securities lending and borrowing and interacts with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. under contract with Euroclear plc, a U.K. corporation. All operations are conducted by

S-20

the Euroclear operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear operator, not Euroclear plc. Euroclear plc establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

The Euroclear operator is a Belgian bank. As such it is regulated by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific clearance accounts. The Euroclear operator acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants.

Distributions with respect to notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

Euroclear has further advised us that investors who acquire, hold and transfer interests in the notes by book-entry through accounts with the Euroclear operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global securities certificates.

Global clearance and settlement procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same Day Funds Settlement System. Secondary market trading between Clearstream participants and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream participants or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving notes through DTC, and making or receiving payment in accordance with normal procedures for same day funds settlement applicable to DTC. Clearstream participants and Euroclear participants may not deliver instructions directly to their respective U.S. depositaries.

Because of time zone differences, credits of notes received through Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the

S-21

business day following the DTC settlement date. Such credits or any transactions in such notes settled during such processing will be reported to the relevant Euroclear participants or Clearstream participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of notes by or through a Clearstream participant or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be modified or discontinued at any time. Neither we nor the paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

Reports

We must file with the trustee copies of our annual reports and the information and other documents which we may be required to file with the SEC under Section 13 or Section 15(d) of the Exchange Act, unless they have been filed on EDGAR, after they are filed with the SEC. We must also file with the trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC, additional information, documents and reports with respect to compliance by RGA with the conditions and covenants of the indenture, as may be required from time to time by such rules and regulations.

About the trustee

The Bank of New York Mellon Trust Company, N.A., is the indenture trustee, and will be the principal paying agent and registrar for the notes. We have entered, and from time to time may continue to enter, into banking or other relationships with The Bank of New York Mellon Trust Company, N.A. or its affiliates. For example, The Bank of New York Mellon Trust Company, N.A. (i) is successor trustee of the indentures relating to our 6.45% Senior Notes due 2019, our 5.00% Senior Notes due 2021 and our Variable Rate Junior Subordinated Debentures due 2065, (ii) is trustee of the indenture relating to our 4.70% Senior Notes due 2023, our 3.95% Senior Notes due 2026, our 6.20% Fixed-to-Floating Rate Subordinated Debentures due 2042 and our 5.75% Fixed-to-Floating Rate Subordinated Debentures due 2056 and (iii) provides other banking and financial services to us.

If the trustee acquires or has a conflicting interest within the meaning of the Trust Indenture Act of 1939, as amended, with respect to the notes, then, within 90 days after ascertaining that it has such conflicting interest, and if the default to which such conflicting interest relates has not been cured or duly waived or otherwise eliminated before the end of such 90-day period, the trustee shall either eliminate such conflicting interest or resign with respect to the notes, and RGA shall take prompt steps to have a successor appointed. The indenture does not prevent the trustee from applying to the SEC for permission to continue as a trustee.

The trustee may resign or be removed with respect to one or more series of debt securities under the indenture, and a successor trustee may be appointed to act with respect to such series.

Miscellaneous

RGA will have the right at all times to assign any of its respective rights or obligations under the indenture to a direct or indirect wholly owned subsidiary of RGA; provided that, in the event of any such assignment, RGA will remain primarily liable for all of its respective obligations. Subject to the foregoing, the indenture will be binding upon and inure to the benefit of the parties thereto and their respective successors and assigns.

S-22

Material U.S. federal income tax consequences

The following is a summary of the material U.S. federal income tax consequences of the purchase, ownership and disposition of the notes. This summary is generally limited to holders that acquire the notes pursuant to this offering at their initial offering price and hold the notes as “capital assets” (generally, property held for investment) for U.S. federal income tax purposes. This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to a holder in light of its particular circumstances or to holders subject to special rules, including, without limitation, tax-exempt organizations, holders subject to the U.S. federal alternative minimum tax, dealers in securities or currencies, traders in securities that elect the mark-to-market method of accounting, financial institutions, insurance companies, regulated investment companies, real estate investment trusts, certain former citizens or residents of the U.S., controlled foreign corporations, passive foreign investment companies, partnerships, S corporations or other pass-through entities, U.S. holders (as defined below) whose functional currency is not the U.S. dollar, persons required to report income with respect to a note no later than when such income is reported on an applicable financial statement and persons that hold the notes in connection with a straddle, hedging, conversion or other risk-reduction transaction.

The U.S. federal income tax consequences set forth below are based upon the Internal Revenue Code of 1986, as amended (the “Code”), and applicable Treasury regulations, court decisions and rulings and pronouncements of the Internal Revenue Service (“IRS”), all as in effect on the date hereof and all of which are subject to change or differing interpretations at any time with possible retroactive effect. There can be no assurance that the IRS will not challenge one or more of the tax consequences described herein, and we have not sought any ruling from the IRS with respect to statements made and conclusions reached in this discussion, and there can be no assurance that the IRS will agree with such statements and conclusions or that a court will not sustain any challenge by the IRS in the event of litigation.

As used herein, the term “U.S. holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes, any of the following:

As used herein, the term “non-U.S. holder” means a beneficial owner of a note that is neither a U.S. holder nor a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A beneficial owner that is a partnership and partners in such a partnership should consult their tax advisors about the U.S. federal income tax consequences of the purchase, ownership and disposition of the notes.

This summary does not address the tax consequences arising under any state, local or foreign law. Furthermore, this summary does not consider the effect of any U.S. federal non-income tax laws, such as U.S. federal estate or gift tax laws.

S-23

Investors considering the purchase of the notes should consult their own tax advisors with respect to the application of the U.S. federal income tax laws to their particular situation, as well as any tax consequences arising under any U.S. federal non-income tax laws (including U.S. federal estate or gift tax laws) and under the laws of any state, local or foreign taxing jurisdiction and under any applicable tax treaty.

Treatment of the Notes

In certain circumstances, we may be obligated to pay amounts in excess of the stated interest or principal on the notes, including as described under “Description of the notes—Optional redemption.” Our obligation to pay such excess amounts may cause the IRS to take the position that the notes are “contingent payment debt instruments” for U.S. federal income tax purposes. If the IRS is successful in such an assertion, the timing and amount of income included and the character of gain recognized with respect to a disposition of the notes may be different from the consequences described herein. Notwithstanding this possibility, we do not believe that the notes are contingent payment debt instruments, and consequently, we do not intend to treat the notes as contingent payment debt instruments. Such determination by us is binding on all holders unless a holder discloses its differing position in the manner required by applicable Treasury regulations. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments for U.S. federal income tax purposes.

U.S. Holders

Payments of Interest

Payments of interest on a note generally will be taxable to a U.S. holder as ordinary interest income at the time such payments are accrued or are received (in accordance with the U.S. holder’s regular method of accounting for U.S. federal income tax purposes).

Original Issue Discount

The notes will not be issued with an issue price that is less than their stated principal amount by more than the statutory de minimis amount. As a result, the notes will not be subject to the original issue discount, or “OID”, rules.

Sale, Redemption, Retirement, Exchange or Other Taxable Disposition of Notes

A U.S. holder will generally recognize gain or loss on the sale, redemption, retirement, exchange or other taxable disposition of a note in an amount equal to the difference between (i) the proceeds received by the holder in exchange for such note (other than amounts properly attributable to accrued but unpaid interest, which, to the extent not previously included in income, will be taxable as interest for U.S. federal income tax purposes) and (ii) the U.S. holder’s adjusted tax basis in the note. The proceeds received by a U.S. holder will include the amount of any cash and the fair market value of any other property received for the note. In general, a U.S. holder’s adjusted tax basis in a note will equal the amount paid for the note. Such gain or loss recognized by a U.S. holder on a disposition of a note will generally be capital gain or loss and will generally be long-term capital gain or loss if the holder held the note for more than one year. Under current U.S. federal income tax law, net long-term capital gains of non-corporate U.S. holders (including individuals) are eligible for taxation at preferential rates. The deductibility of capital losses is subject to certain limitations. Prospective investors should consult with their own tax advisors concerning these tax law provisions.

Medicare Tax

A U.S. holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) the U.S. holder’s “net investment income” (or undistributed “net investment income” in the case of an estate or trust) for the relevant taxable year or (2) the

S-24

excess of the U.S. holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s circumstances). A holder’s net investment income will generally include its interest income and its net gains from the disposition of notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities), less deductions allowed under the Code against such interest income or gains from the notes. If you are a U.S. holder that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the notes.

Information Reporting and Backup Withholding

Unless a U.S. holder is an exempt recipient, such as a corporation, payments made with respect to the notes or proceeds from the disposition of the notes (including a redemption or retirement of the notes) may be subject to information reporting and may also be subject to U.S. federal backup withholding at the applicable rate if such U.S. holder fails to comply with applicable U.S. information reporting and certification requirements.

Backup withholding is not an additional tax. Any amount withheld from a payment to you under the backup withholding rules generally will be allowed as a refund or a credit against your U.S. federal income tax liability, provided the required information is furnished timely to the IRS.

Non-U.S. Holders

Payments of Interest

Generally, interest paid on a note by us or our agent to a non-U.S. holder will qualify for the “portfolio interest exemption” and, subject to the discussions below regarding backup withholding and FATCA (as defined below), will not be subject to U.S. federal income tax or withholding tax; provided that such interest income is not effectively connected with a U.S. trade or business of the non-U.S. holder; and provided that the non-U.S. holder:

If such non-U.S. holder cannot satisfy the requirements described above, payments of interest made to the non-U.S. holder will be subject to 30% U.S. federal tax withholding unless (i) the interest is effectively connected with a U.S. trade or business of such non-U.S. holder and such non-U.S. holder satisfies the applicable certification requirements (as discussed below) or (ii) such holder provides the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or a suitable substitute form), as applicable, claiming an exemption from (or reduction of) withholding under the benefit of a tax treaty.

S-25

If interest on a note is, or is deemed to be, effectively connected with a U.S. trade or business of a non-U.S. holder (and, if required by an applicable tax treaty, is attributable to a permanent establishment or fixed base maintained by the non-U.S. holder within the U.S.), the non-U.S. holder generally will not be subject to withholding if the non-U.S. holder complies with applicable IRS certification requirements (i.e., by delivering a properly executed IRS Form W-8ECI or a suitable substitute form) and generally will be subject to U.S. federal income tax on a net income basis at regular graduated rates in the same manner as if the holder were a U.S. holder. In the case of a non-U.S. holder that is a corporation (or other entity treated as a corporation for U.S. federal income tax purposes), such effectively connected income also may be subject to an additional branch profits tax, which generally is imposed on a foreign corporation on the deemed repatriation from the U.S. of effectively connected earnings and profits at a 30% rate (or such lower rate as may be prescribed by an applicable tax treaty).

Sale, Redemption, Retirement, Exchange or Other Taxable Disposition of Notes

Subject to the discussions below regarding backup withholding and FATCA, any gain recognized by a non-U.S. holder on the sale, redemption, retirement, exchange or other taxable disposition of a note (other than amounts properly attributable to accrued but unpaid interest, which are treated as described under “Non-U.S. Holders—Payments of Interest” above) will not be subject to U.S. federal income tax or withholding, unless:

A non-U.S. holder should consult his or her tax advisor regarding the tax consequences of the disposition of the notes.

Information Reporting and Backup Withholding

Non-U.S. holders may be required to comply with certain certification procedures to establish that the holder is not a U.S. person in order to avoid information reporting and backup withholding with respect to payments on the notes or proceeds from the disposition of the notes. Information returns generally will be filed with the IRS, however, in connection with payments of interest on the notes to non-U.S. holders.

Backup withholding is not an additional tax. Any amount withheld from a payment to you under the backup withholding rules generally will be allowed as a refund or a credit against your U.S. federal income tax liability, provided the required information is furnished timely to the IRS.

Non-U.S. holders should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedures for obtaining such an exemption, if available.

Additional Withholding Requirements

Pursuant to Sections 1471 through 1474 of the Code and the Treasury regulations promulgated thereunder and related administrative guidance (“FATCA”), a 30% U.S. federal withholding tax may apply to withholdable payments (including payments of interest on the notes) made to non-U.S. financial institutions and certain other

S-26

non-U.S. non-financial entities (including, in some instances, where such an entity is acting as an intermediary) that fail to comply with certain information reporting and due diligence obligations. Such an entity can generally establish its exemption from FATCA withholding by providing the applicable withholding agent with a properly executed IRS Form W-8BEN-E (or other applicable form). Non-U.S. entities that are organized in a jurisdiction that has entered into an intergovernmental agreement with the U.S. regarding FATCA may be subject to different rules. If an amount in respect of U.S. withholding tax were to be deducted or withheld from interest on the notes as a result of a holder’s failure to comply with these rules or the presence in the payment chain of an intermediary that does not comply with these rules, neither the issuer nor any paying agent nor any other person would be required to pay additional amounts as a result of the deduction or withholding of such tax. As a result, investors may receive less interest than expected.

Under applicable final Treasury regulations, withholding under FATCA generally applies to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019. However, pursuant to recently proposed Treasury regulations (upon which taxpayers may generally rely until applicable final regulations are issued or such proposed Treasury regulations are rescinded), gross proceeds from the sale or other disposition of a note will not be subject to withholding under FATCA. Non-U.S. holders should consult their own tax advisors regarding FATCA and whether it may be relevant to their purchase, ownership and disposition of the notes.

The U.S. federal income tax summary set forth above is included for general information only and may not be applicable depending upon your particular situation. You should consult your own tax advisors with respect to the tax consequences to you of the purchase, ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in federal or other tax laws.

S-27

Underwriting

Under the terms and subject to the conditions contained in an underwriting agreement dated May 8, 2019, the underwriters named below, for whom J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets, LLC and Wells Fargo Securities, LLC are acting as representatives (the “representatives”), have severally agreed to purchase from us, and we have agreed to sell, the aggregate principal amount of the notes listed opposite their names below:

The underwriting agreement provides that the underwriters are severally obligated to purchase all of the notes if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering of notes may be terminated.

We have been advised by the representatives that the underwriters propose to offer the notes directly to the public at the applicable public offering price set forth on the cover page of this prospectus supplement, and the underwriters may sell the notes to certain dealers at the public offering price less a concession not in excess of 0.400% of the aggregate principal amount of the notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.250% of the aggregate principal amount of the notes to certain other dealers. After the initial public offering of the notes to the public, the underwriters may change the public offering price and concession and other selling terms.

The following table shows the underwriting discount that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

We estimate that our total expenses for this offering, excluding the underwriting discount, will be approximately $850,000 and payable by us.

The notes are a new issue of securities with no established trading market. We have not applied for and do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any automated dealer quotation system. The representatives have advised us that the underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.

S-28

We have agreed to indemnify the underwriters against liabilities under the Securities Act of 1933, as amended, or contribute to payments which the underwriters may be required to make in that respect.

In connection with the offering the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids under the Exchange Act.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time.

The underwriters and/or their affiliates have provided and in the future may provide investment banking, commercial banking, advisory, reinsurance and/or other financial services to us and our affiliates from time to time for which they have received and in the future may receive customary fees and expenses and may have entered into and in the future may enter into other transactions with us. In addition, certain of the underwriters or their affiliates are agents and/or lenders under our syndicated revolving credit facility, dated as of August 21, 2018.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Selling Restrictions

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws. The underwriters may reject any order for notes in whole or in part.

S-29

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement or the accompanying prospectus (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (“NI 33-105”), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

Prohibition of Sales to European Economic Area Retail Investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”), (ii) a customer within the meaning of Directive 2002/92/EC (as amended or superseded, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended or superseded, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Directive.

This prospectus supplement, the accompanying prospectus and their contents are confidential and should not be distributed, published or reproduced (in whole or in part) or disclosed by any recipients to any other person in the United Kingdom. Any person in the United Kingdom that is not a Relevant Person should not act or rely on this prospectus supplement, the accompanying prospectus or their contents.

Switzerland

This prospectus supplement and the accompanying prospectus do not constitute an issue prospectus pursuant to Article 652a or Article 1156 of the Swiss Code of Obligations and the notes will not be listed on the SIX Swiss Exchange. Therefore, this prospectus supplement may not comply with the disclosure standards of the listing rules (including any additional listing rules or prospectus schemes) of the SIX Swiss Exchange. Accordingly, the notes may not be offered to the public in or from Switzerland, but only to a selected and limited circle of investors who do not subscribe to the notes with a view to distribution. Any such investors will be individually approached by the underwriters from time to time.

Singapore

This prospectus supplement and the accompanying prospectus have not been and will not be registered as a prospectus with the Monetary Authority of Singapore under the Securities and Futures Act, Chapter 289 of Singapore (the ‘‘SFA’’). Accordingly, each underwriter has not offered or sold any notes or caused such notes to be made the subject of an invitation for subscription or purchase and will not offer or sell such notes or cause such notes to be made the subject of an invitation for subscription or purchase, and has not circulated or distributed, nor will it circulate or distribute, this prospectus supplement, the accompanying prospectus or any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of such notes, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor under Section 274 of the SFA, (ii) to a relevant person pursuant to Section 275(1), or any person pursuant to Section 275(1A), and in accordance with the conditions specified in Section 275, of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

Where the notes are subscribed or purchased under Section 275 of the SFA by a relevant person which is: (a) a corporation (which is not an accredited investor (as defined in Section 4A of the SFA)) the sole business of which is to hold investments and the entire share capital of which is owned by one or more individuals, each of whom is an accredited investor or (b) a trust (where the trustee is not an accredited investor) whose sole purpose is to hold investments and each beneficiary of the trust is an individual who is an accredited investor, securities (as defined in Section 239(1) of the SFA) of that corporation or the beneficiaries’ rights and interest (howsoever described) in that trust shall not be transferred within six months after that corporation or that trust has acquired the notes pursuant to an offer made under Section 275 of the SFA, except: (i) to an institutional investor under Section 274 of the SFA or to a relevant person (as defined in Section 275(2) of the SFA), or to any person arising

Singapore Securities and Futures Act Product Classification—Solely for the purposes of its obligations pursuant to sections 309B(1)(a) and 309B(1)(c) of the Securities and Futures Act (Chapter 289 of Singapore) (the ‘‘SFA’’), the Company has determined, and hereby notifies all relevant persons (as defined in Section 309A of the SFA) that the notes are ‘‘prescribed capital markets products’’ (as defined in the Securities and Futures (Capital Markets Products) Regulations 2018) and Excluded Investment Products (as defined in MAS Notice SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on Recommendations on Investment Products).

Settlement

It is expected that delivery of the notes will be made against payment therefor on or about May 15, 2019, which is the fifth business day following the date hereof (such settlement cycle being referred to as “T+5”). Pursuant to Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to two business days before the date of delivery of the notes in this offering will be required, by virtue of the fact that the notes initially will settle in T+5, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to two business days before the date of delivery of the notes in this offering should consult their own advisors.

The current business of Merrill Lynch, Pierce, Fenner & Smith Incorporated (“MLPF&S”) is being reorganized into two affiliated broker-dealers (i.e., MLPF&S and BofA Securities, Inc.) in which BofA Securities, Inc. will be the new legal entity for the institutional services that are now provided by MLPF&S. This transfer is expected to occur on or around May 13, 2019 (the “Transfer Date”). MLPF&S, an underwriter of the notes, will be assigning its rights and obligations as an underwriter to BofA Securities, Inc. in the event that the settlement date for the notes occurs on or after the Transfer Date.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

INFORMATION ABOUT THE RGA TRUSTS

Each of the RGA trusts is a statutory trust formed under Delaware law. Each RGA trust exists for the exclusive purposes of:

All of the common securities of each trust will be directly or indirectly owned by RGA. The common securities will rank equally, and payments will be made proportionally, with the preferred securities. However, if an event of default under the amended and restated trust agreement of the respective RGA trust has occurred and is continuing, the cash distributions and liquidation, redemption and other amounts payable on the common securities will be subordinated to the preferred securities in right of payment. We will directly or indirectly acquire common securities in an amount equal to at least 3% of the total capital of each RGA trust. The preferred securities will represent the remaining 97% of such trusts’ capital.

RGA will guarantee the preferred securities of each RGA trust as described later in this prospectus.

Unless otherwise specified in the applicable prospectus supplement or other offering material, each RGA trust has a term of up to 55 years but may terminate earlier, as provided in its amended and restated trust agreement. Each RGA trust’s business and affairs will be conducted by the trustees appointed by us. According to the amended and restated trust agreement of each RGA trust, as the holder of all of the common securities of an RGA trust, we can increase or decrease the number of trustees of each trust, subject to the requirement under Delaware law that there be a trustee in the State of Delaware and to the provisions of the Trust Indenture Act of 1939 (the “Trust Indenture Act”). The amended and restated trust agreement will set forth the duties and obligations of the trustees. A majority of the trustees of each RGA trust will be employees or officers of or persons who are affiliated with RGA, whom we refer to as “administrative trustees.”

One trustee of each RGA trust will be an institution, which we refer to as the “property trustee,” that is not affiliated with RGA and has a minimum amount of combined capital and surplus of not less than $50,000,000, which will act as property trustee and as indenture trustee for the purposes of compliance with the provisions of the Trust Indenture Act, under the terms of the applicable prospectus supplement. Unless otherwise indicated in the applicable prospectus supplement, the property trustee will maintain exclusive control of a segregated, non-interest bearing “payment account” established with The Bank of New York Mellon Trust Company, N.A. to hold all payments made on the junior subordinated debt securities for the benefit of the holders of the trust securities of each RGA trust. In addition, unless the property trustee maintains a principal place of business in the State of Delaware and otherwise meets the requirements of applicable law, one trustee of each RGA trust will be an institution having a principal place of business in, or a natural person resident of, the State of Delaware, which we refer to as the “Delaware trustee.” As the direct or indirect holder of all of the common securities, RGA will be entitled to appoint, remove or replace any of, or increase or reduce the number of, the trustees of each RGA trust, except that if an event of default under the junior subordinated indenture has occurred and is continuing, only the holders of preferred securities may remove the Delaware trustee or the property trustee. RGA will pay all fees and expenses related to the RGA trust and the offering of the preferred securities and the common securities.

Unless otherwise specified in the applicable prospectus supplement or other offering material, the property trustee for each RGA trust will be The Bank of New York Mellon Trust Company, N.A. Unless otherwise specified in the applicable prospectus supplement, the Delaware trustee for each RGA trust will be BNY Mellon Trust of Delaware, an affiliate of The Bank of New York Mellon Trust Company, N.A., and its address in the

7

state of Delaware is Bellevue Park Corporate Center, 301 Bellevue Parkway, 3^rd Floor, Wilmington, Delaware 19809. The principal place of business of each RGA trust is c/o Reinsurance Group of America, Incorporated, 16600 Swingley Ridge Road, Chesterfield, Missouri 63017-1706, telephone (636) 736-7000.

The RGA trusts will not have separate financial statements. The statements would not be material to holders of the preferred securities because the trusts will not have any independent operations. Each of the trusts exists solely for the reasons provided in the amended and restated trust agreement and summarized above. Unless otherwise provided in the applicable prospectus supplement or other offering material, RGA will pay all fees and expenses related to each RGA trust and the offering of its preferred securities, including the fees and expenses of the trustee.

8

USE OF PROCEEDS

Unless otherwise stated in the prospectus supplement or other offering material, we will use the net proceeds from the sale of any securities offered by RGA for general corporate purposes, including the funding of our reinsurance operations. Except as otherwise described in a prospectus supplement or other offering material, the proceeds from the sale by any RGA trust of any preferred securities, together with any capital contributed in respect of common securities, will be loaned to RGA in exchange for RGA’s junior subordinated debt securities. Unless otherwise stated in the prospectus supplement or other offering material, we will use the borrowings from the RGA trusts for general corporate purposes, including the funding of our reinsurance operations. Such general corporate purposes may include, but are not limited to, repayments of our indebtedness or the indebtedness of our subsidiaries. Pending such use, the proceeds may be invested temporarily in short-term, interest-bearing, investment-grade securities or similar assets. The prospectus supplement or other offering material relating to an offering will contain a more detailed description of the use of proceeds of any specific offering of securities. Except as may otherwise be specified in the applicable prospectus supplement, we will not receive any proceeds from any sales of securities by any selling security holder.

SELLING SECURITY HOLDERS

We may register securities covered by this prospectus for re-offers and resales by any selling security holders to be named in a prospectus supplement. Because we are a well-known seasoned issuer, as defined in Rule 405 of the Securities Act, we may add secondary sales of securities by any selling security holders by filing a prospectus supplement with the SEC. We may register these securities to permit selling security holders to resell their securities when they deem appropriate. A selling security holder may resell all, a portion or none of such security holder’s securities at any time and from time to time. Selling security holders may also sell, transfer or otherwise dispose of some or all of their securities in transactions exempt from the registration requirements of the Securities Act. We do not know when or in what amounts any selling security holders may offer securities for sale under this prospectus and any prospectus supplement. We may pay some or all expenses incurred with respect to the registration of the securities owned by the selling security holders. We will provide a prospectus supplement naming any selling security holders, the amount of securities to be registered and sold and any other terms of securities being sold by each selling security holder.

RATIO OF EARNINGS TO FIXED CHARGES AND

RATIO OF COMBINED FIXED CHARGES AND PREFERENCE DIVIDENDS TO EARNINGS

The following table sets forth our ratios of earnings to fixed charges and earnings to fixed charges, excluding interest credited under reinsurance contracts, for the periods indicated.

For purposes of computing the consolidated ratio of earnings to fixed charges, earnings consist of net earnings from continuing operations adjusted for the provision for income taxes and fixed charges. Fixed charges consist of interest and discount on all indebtedness, distribution requirements of wholly-owned subsidiary trust preferred securities and floating rate insured notes and one-third of annual rentals, which we believe is a reasonable approximation of the interest factor of such rentals. We have not paid a preference security dividend for any of the periods presented and accordingly have not separately shown the ratio of combined fixed charges and preference dividends to earnings for these periods.

The information below regarding RGA’s ratio of earnings to fixed charges excluding interest credited under reinsurance contracts is not required; however, we believe it provides useful information on the coverage of fixed charges that are not related to our products.

DESCRIPTION OF THE SECURITIES WE MAY OFFER

We, any RGA trust, or any selling security holder may offer or sell from time to time, in one or more offerings, the following securities:

This prospectus contains a summary of the material general terms of the various securities that we, any RGA trust, or any selling security holder may offer. The specific terms of the securities will be described in a prospectus supplement or other offering material, which may be in addition to or different from the general terms summarized in this prospectus. Where applicable, the prospectus supplement or other offering material will also describe any material United States federal income tax considerations relating to the securities offered and indicate whether the securities offered are or will be listed on any securities exchange. The summaries contained in this prospectus and in any prospectus supplements or other offering material do not contain all of the information or restate the agreements under which the securities may be issued and do not contain all of the information that you may find useful. We urge you to read the actual agreements relating to any securities because they, and not the summaries, define your rights as a holder of the securities. If you would like to read the agreements, they will be on file with the SEC, as described under “Where You Can Find More Information” on page 2 and “Incorporation of Certain Documents by Reference” on page 3.

The terms of any offering, the initial offering price, the net proceeds to us and any other relevant provisions will be contained in the prospectus supplement or other offering material relating to such offering.

DESCRIPTION OF DEBT SECURITIES OF RGA

The following description of the terms of the debt securities sets forth the material terms and provisions of the debt securities to which any prospectus supplement or other offering material may relate. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities so offered and any changes to or differences from those general terms will be described in the prospectus supplement or other offering material relating to such debt securities. The debt securities will be either our senior debt securities or subordinated debt securities, or our junior subordinated debt securities, which may, but need not be, issued in connection with the issuance by an RGA trust of its trust preferred securities.

The Indentures

The senior and subordinated debt securities will be issued in one or more series under an Indenture dated as of August 21, 2012 between us and The Bank of New York Mellon Trust Company, N.A., as trustee. The junior subordinated debt securities will be issued in one or more series under a Junior Subordinated Indenture, to be entered into between us and The Bank of New York Mellon Trust Company, N.A., as trustee. The statements

10

herein relating to the debt securities and the indentures are summaries and are subject to, and are qualified in their entirety by reference to, the detailed provisions of the applicable indenture. Whenever we refer to particular sections or defined terms of the Indenture in this prospectus or in any prospectus supplement, those sections or defined terms are incorporated by reference here or in the applicable prospectus supplement. Reference is hereby made to the Indenture, which has been filed as an exhibit to the Current Report on Form 8-K filed on August 21, 2012 and incorporated by reference in this registration statement. The Indenture is, and the Junior Subordinated Indenture will be, subject to and governed by the Trust Indenture Act. The description of the indentures set forth below assumes that we have entered into both of the indentures. We will execute the Junior Subordinated Indenture when and if we issue junior subordinated debt securities.

General

The indentures do not limit the aggregate amount of debt securities which we may issue. We may issue debt securities under the indentures up to the aggregate principal amount authorized by our board of directors from time to time. Except as may be described in a prospectus supplement or other offering material, the indentures will not limit the amount of other secured or unsecured debt that we may incur or issue.

The debt securities will be our unsecured general obligations. The senior debt securities will rank with all our other unsecured and unsubordinated obligations. The subordinated debt securities will be subordinated and junior in right of payment to all our present and future senior indebtedness to the extent and in the manner set forth in the applicable prospectus supplement or other offering material. Unless otherwise specified in the applicable prospectus supplement or other offering material, the junior subordinated debt securities that we may issue to one of the RGA trusts will be subordinated and junior in right of payment to all our present and future indebtedness, including any senior and subordinated debt securities issued under the indenture to the extent and in the manner set forth in the junior subordinated indenture. See “— Subordination,” beginning on page 17. The indentures will provide that the debt securities may be issued from time to time in one or more series. We may authorize the issuance and provide for the terms of a series of debt securities pursuant to a supplemental indenture.

We are a holding company. As a result, we may rely primarily on dividends or other payments from our operating subsidiaries to pay principal and interest on our outstanding debt obligations, and to make dividend distributions on our capital stock. The principal source of funds for these operating subsidiaries comes from their current operations. We can also utilize investment securities maintained in our portfolio for these payments.

Applicable insurance regulatory and other legal restrictions limit the amount of dividends and other payments our subsidiaries can make to us. Our subsidiaries have no obligation to guarantee or otherwise pay amounts due under the debt securities. Therefore, the debt securities will be effectively subordinated to all indebtedness and other liabilities and commitments of our subsidiaries, including claims under reinsurance contracts, debt obligations and other liabilities incurred in the ordinary course of business. As of March 31, 2017, our consolidated short- and long-term indebtedness aggregated approximately $2.8 billion and our subsidiaries had approximately $42.2 billion of outstanding liabilities reflected in our financial statements, which includes $441.7 million of liabilities associated with the floating rate insured notes issued by our subsidiary, Timberlake Financial, L.L.C., $149.4 million of liabilities associated with the collateral financing obtained by our subsidiary, RGA Reinsurance Company (Barbados) Ltd. and $234.4 million of liabilities associated with the asset-backed notes issued by our subsidiary, Chesterfield Financial Holdings LLC. We will disclose material changes to these amounts in any prospectus supplement or other offering material relating to an offering of our debt securities. In the event of a default on any debt securities, the holders of the debt securities will have no right to proceed against the assets of any insurance subsidiary. If the subsidiary were to be liquidated, the liquidation would be conducted under the laws of the applicable jurisdiction. Our right to receive distributions of assets in any liquidation of a subsidiary would be subordinated to the claims of the subsidiary’s creditors, except to the extent any claims of ours as a creditor would be recognized. Any recognized claims of ours would be subordinated to any prior security interest held by any other creditors of the subsidiary and obligations of the subsidiary that are senior to those owing to us.

11

The applicable prospectus supplement or other offering material relating to the particular series of debt securities will describe specific terms of the debt securities offered thereby, including any terms that are additional or different from those described in this prospectus (Section 3.1 of each indenture).

Unless otherwise specified in the applicable prospectus supplement or other offering material, the debt securities will not be listed on any securities exchange.

None of our shareholders, officers or directors, past, present or future, will have any personal liability with respect to our obligations under the indenture or the debt securities on account of that status. (Section 1.14 of each indenture).

Form and Denominations

Unless otherwise specified in the applicable prospectus supplement or other offering material, debt securities will be issued only in fully registered form, without coupons, and will be denominated in U.S. dollars issued in denominations of U.S. $1,000 and any integral multiple thereof. (Section 3.2 of each indenture).

Global Debt Securities

Unless otherwise specified in a prospectus supplement or other offering material for a particular series of debt securities, each series of debt securities will be issued in whole or in part in global form that will be deposited with, or on behalf of, a depositary identified in the prospectus supplement or other offering material relating to that series. Global securities will be registered in the name of the depositary, which will be the sole direct holder of the global securities. Any person wishing to own a debt security must do so indirectly through an account with a broker, bank or other financial institution that, in turn, has an account with the depositary.

Special Investor Considerations for Global Securities. Under the terms of the indentures, our obligations with respect to the debt securities, as well as the obligations of each trustee, run only to persons who are registered holders of debt securities. For example, once we make payment to the registered holder, we have no further responsibility for that payment even if the recipient is legally required to pass the payment along to an individual investor but fails to do so. As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to transfers of debt securities.

An investor should be aware that when debt securities are issued in the form of global securities:

Neither we nor the trustees have any responsibility for any aspect of the depositary’s actions or for its records of ownership interests in the global security, and neither we nor the trustees supervise the depositary in any way.

12

Special Situations When the Global Security Will Be Terminated. In a few special situations described below, the global security will terminate, and interests in the global security will be exchanged for physical certificates representing debt securities. After that exchange, the investor may choose whether to hold debt securities directly or indirectly through an account at the investor’s bank or brokerage firm. In that event, investors must consult their banks or brokers to find out how to have their interests in debt securities transferred to their own names so that they may become direct holders.

The special situations where a global security is terminated are:

A prospectus supplement or other offering material may list situations for terminating a global security that would apply only to a particular series of debt securities. When a global security terminates, the depositary, and not us or one of the trustees, is responsible for deciding the names of the institutions that will be the initial direct holders.

Original Issue Discount Securities

Debt securities may be sold at a substantial discount below their stated principal amount and may bear no interest or interest at a rate which at the time of issuance is below market rates. Important federal income tax consequences and special considerations applicable to any such debt securities will be described in the applicable prospectus supplement.

Indexed Securities

If the amount of payments of principal of, and premium, if any, or any interest on, debt securities of any series is determined with reference to any type of index or formula or changes in prices of particular securities or commodities, the federal income tax consequences, specific terms and other information with respect to such debt securities and such index or formula and securities or commodities will be described in the applicable prospectus supplement or other offering material.

Foreign Currencies

If the principal of, and premium, if any, or any interest on, debt securities of any series are payable in a foreign or composite currency, the restrictions, elections, federal income tax consequences, specific terms and other information with respect to such debt securities and such currency will be described in the applicable prospectus supplement or other offering material.

Payment

Unless otherwise indicated in the applicable prospectus supplement or other offering material, payments in respect of the debt securities will be made in the designated currency at the office or agency of RGA maintained for that purpose as RGA may designate from time to time, except that, at the option of RGA, interest payments, if any, on debt securities may be made by checks mailed to the holders of debt securities entitled thereto at their registered addresses. (Section 3.7 of each indenture).

Payment of Interest With Respect to Debt Securities

Unless otherwise indicated in an applicable prospectus supplement or other offering material, payment of any installment of interest on debt securities will be made to the person in whose name such debt security is registered at the close of business on the regular record date for such interest. (Section 3.7 of each indenture).

13

Transfer and Exchange

Unless otherwise indicated in the applicable prospectus supplement or other offering material, debt securities will be transferable or exchangeable at the agency of RGA maintained for such purpose as designated by RGA from time to time. Debt securities may be transferred or exchanged without service charge, other than any tax or other governmental charge imposed in connection with such transfer or exchange. (Section 3.5 of each indenture).

Consolidation, Merger, Conveyance, Sale of Assets and Other Transfers

We may not consolidate with or merge with or into or wind up into, whether or not we are the surviving corporation, or sell, assign, convey, transfer or lease substantially all of our properties and assets, in one transaction or a series of related transactions, to any person, unless:

Upon the consolidation, merger or sale, the successor corporation formed by the consolidation, or into which we are merged or to which the sale is made, will succeed to, and be substituted for us under each indenture. (Section 9.2 of each indenture).

Unless a prospectus supplement or other offering material relating to a particular series of debt securities provides otherwise, the indenture and the terms of the debt securities will not contain any covenants designed to afford holders of any debt securities protection in a highly leveraged or other transaction involving us, whether or not resulting in a change of control, which may adversely affect holders of the debt securities.

Option to Extend Interest Payment Period

If indicated in the applicable prospectus supplement or other offering material, we will have the right, as long as no event of default under the applicable series of debt securities has occurred and is continuing, at any time and from time to time during the term of the series of debt securities to defer the payment of interest on one or more series of debt securities for the number of consecutive interest payment periods specified in the applicable prospectus supplement or other offering material, subject to the terms, conditions and covenants, if any, specified in the prospectus supplement or other offering material, provided that no extension period may extend beyond the stated maturity of the debt securities. Material United States federal income tax consequences and special considerations applicable to these debt securities will be described in the applicable prospectus supplement or other offering material. Unless otherwise indicated in the applicable prospectus supplement or other offering material, at the end of the extension period, we will pay all interest then accrued and unpaid together with interest on accrued and unpaid interest compounded semiannually at the rate specified for the debt securities to the extent permitted by applicable law. However, unless otherwise indicated in the applicable prospectus supplement or other offering material, during the extension period neither we nor any of our subsidiaries may:

(1) purchases of our capital stock in connection with any employee or agent benefit plans or the satisfaction of our obligations under any contract or security outstanding on the date of the event requiring us to purchase capital stock,

14

(2) in connection with the reclassifications of any class or series of our capital stock, or the exchange or conversion of one class or series of our capital stock for or into another class or series of our capital stock,

(3) the purchase of fractional interests in shares of our capital stock in connection with the conversion or exchange provisions of that capital stock or the security being converted or exchanged,

(4) dividends or distributions in our capital stock, or rights to acquire capital stock, or repurchases or redemptions of capital stock solely from the issuance or exchange of capital stock, or

(5) any non-cash dividends declared in connection with the implementation of a shareholder rights plan by us;

Prior to the termination of any extension period, as long as no event of default under the applicable indenture has occurred and is continuing, we may further defer payments of interest, subject to the above limitations set forth in this section, by extending the interest payment period; provided, however, that, the extension period, including all previous and further extensions, may not extend beyond the maturity of the debt securities.

Upon the termination of any extension period and the payment of all amounts then due, we will have the right to commence a new extension period, subject to the above limitations set forth in this section. No interest will be payable during an extension period; instead, interest will only be due and payable at the end of the extension period. However, we will have the right to prepay at any time all or any portion of the interest accrued during an extension period. We do not currently intend to exercise our right to defer payments of interest by extending the interest payment period on the debt securities. In the case of our junior subordinated debt securities, if the property trustee is the sole holder of such debt securities, we will give the administrative trustees and the property trustee notice of our selection of an extension period two business days before the earlier of (1) the next succeeding date on which distributions on the preferred securities are payable or (2) the date the administrative trustees are required to give notice to the New York Stock Exchange, or other applicable self-regulatory organization, or to holders of the preferred securities of the record or payment date of the distribution, but in any event, at least one business day before such record date. The administrative trustees will give notice of our selection of the extension period to the holders of the preferred securities. If the property trustee is not the sole holder of such debt securities, or in the case of the senior and subordinated debt securities, we will give the holders of these debt securities notice of our selection of an extension period at least two business days before the earlier of (1) the next succeeding interest payment date or (2) the date upon which we are required to give notice to the New York Stock Exchange, or other applicable self-regulatory organization, or to holders of such debt securities of the record or payment date of the related interest payment. (Article XVII of the junior subordinated indenture).

Modification or Amendment of the Indentures

Supplemental Indentures Without Consent of Holders. Without the consent of any holders, we and the trustee may enter into one or supplemental indentures for certain purposes, including:

(1) to evidence the succession of another corporation to our rights and the assumption by such successor of the covenants contained in each indenture;

(2) to add to our covenants for the benefit of all or any series of debt securities, or to surrender any of our rights or powers;

15

(3) to add any additional events of default;

(4) to change or eliminate any provisions, as long as any such change or elimination is effective only when there are no outstanding debt securities of any series created before the execution of such supplemental indenture which is entitled to the benefit of the provisions being changed or eliminated;

(5) to provide security for or guarantee of the debt securities;

(6) to supplement any of the provisions to permit or facilitate the defeasance and discharge of any series of debt securities in accordance with such indenture;

(7) to establish the form or terms of debt securities in accordance with each indenture;

(8) to provide for the acceptance of the appointment of a successor trustee for any series of debt securities or to provide for or facilitate the administration of the trusts under the indenture by more than one trustee;

(9) to cure any ambiguity, to correct or supplement any provision of any indenture which may be defective or inconsistent with any other provision, to eliminate any conflict with the Trust Indenture Act or to make any other provisions with respect to matters or questions arising under such indenture which are not inconsistent with any provision of the indenture, as long as the additional provisions do not adversely affect the interests of the holders in any material respect;

(10) to change the conversion rights;

(11) to make any change that does not adversely affect the interests of the holders in any material respect; or

(12) in the case of the junior subordinated indenture, to modify the subordination provisions thereof, except in a manner which would be adverse to the holders of subordinated or junior subordinated debt securities of any series then outstanding. (Section 10.1 of each indenture).

Supplemental Indentures with Consent of Holders. If we receive the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected, we may enter into supplemental indentures with the trustee for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of each indenture or of modifying in any manner the rights of the holders under the indenture of such debt securities. As long as any of the preferred securities of an RGA trust remain outstanding, no modification of the related junior subordinated indenture may be made that requires the consent of the holders of the related junior subordinated debt securities, no termination of the related junior subordinated indenture may occur, and no waiver of any event of default under the related junior subordinated indenture may be effective, without the prior consent of the holders of a majority of the aggregate liquidation amount of the preferred securities of such RGA trust.

However, unless we receive the consent of all of the affected holders, we may not enter into supplemental indentures that would, with respect to the debt securities of such holders:

(1) conflict with the required provisions of the Trust Indenture Act;

(2) except as described in any prospectus supplement or other offering material:

16

(3) reduce the requirement for majority approval of supplemental indentures, or for waiver of compliance with certain provisions of either indenture or certain defaults; or

(4) modify any provisions of either indenture relating to waiver of past defaults with respect to that series, except to increase any such percentage or to provide that certain other provisions of such indenture cannot be modified or waived without the consent of the holders of each such debt security of each series affected thereby. (Section 10.2 of each indenture).

It is not necessary for holders of the debt securities to approve the particular form of any proposed supplemental indenture, but it is sufficient if the holders approve the substance thereof. (Section 10.2 of each indenture).

A supplemental indenture which changes or eliminates any covenant or other provision of the indenture to which it relates with respect to one or more particular series of debt securities or which modifies the rights of the holders of debt securities of such series with respect to such covenant or other provision, will be deemed not to affect the rights under such indenture of the holders of debt securities of any other series. (Section 10.2 of each indenture).

Subordination

The subordinated debt securities will be subordinated and junior in right of payment to all our present and future senior indebtedness to the extent and in the manner set forth in the applicable prospectus supplement or other offering material. In the junior subordinated indenture, RGA has covenanted and agreed that any junior subordinated debt securities issued thereunder are subordinated and junior in right of payment to all present and future senior indebtedness to the extent provided in the indenture. (Section 16.1 of the junior subordinated indenture). Unless otherwise indicated in the applicable prospectus supplement or other offering material, the junior subordinated indenture defines the term “senior indebtedness” with respect to each respective series of junior subordinated debt securities, to mean the principal, premium, if any, and interest on:

In the case of the junior subordinated indenture, unless otherwise indicated in the applicable prospectus supplement or other offering material, senior indebtedness also includes all subordinated debt securities issued under the indenture. The senior indebtedness will continue to be senior indebtedness and entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of the senior indebtedness or extension or renewal of the senior indebtedness. Unless otherwise indicated in the applicable prospectus supplement or other offering material, notwithstanding anything to the contrary in the foregoing, senior indebtedness will not include (A) indebtedness incurred for the purchase of goods or materials or for

17

services obtained in the ordinary course of business and (B) any indebtedness which by its terms is expressly made pari passu, or equal in rank and payment, with or subordinated to the junior subordinated debt securities. (Section 16.2 of the junior subordinated indenture).

Unless otherwise indicated in the applicable prospectus supplement or other offering material, no direct or indirect payment, in cash, property or securities, by set-off or otherwise, shall be made or agreed to be made on account of the junior subordinated debt securities or interest thereon or in respect of any repayment, redemption, retirement, purchase or other acquisition of such junior subordinated debt securities, if:

Unless otherwise indicated in the applicable prospectus supplement or other offering material, all present and future senior indebtedness, which shall include subordinated indebtedness in the case of our junior subordinated debt securities, including, without limitation, interest accruing after the commencement of any proceeding described below, assignment or marshaling of assets, shall first be paid in full before any payment or distribution, whether in cash, securities or other property, shall be made by RGA on account of junior subordinated debt securities in the event of:

Unless otherwise indicated in the applicable prospectus supplement or other offering materials, in any such event, payments or distributions which would otherwise be made on junior subordinated debt securities will generally be paid to the holders of senior indebtedness, or their representatives, in accordance with the priorities existing among these creditors at that time until the senior indebtedness is paid in full. (Section 16.3 of the junior subordinated indenture). No present or future holder of any senior indebtedness will be prejudiced in the right to enforce the subordination of junior subordinated debt securities by any act or failure to act on the part of RGA. (Section 16.9 of the junior subordinated indenture).

Senior indebtedness will only be deemed to have been paid in full if the holders of such indebtedness have received cash, securities or other property which is equal to the amount of the outstanding senior indebtedness. After payment in full of all present and future senior indebtedness, holders of junior subordinated debt securities will be subrogated to the rights of any holders of senior indebtedness to receive any further payments or distributions that are applicable to the senior indebtedness until all the junior subordinated debt securities are paid in full. In matters between holders of junior subordinated debt securities and any other type of RGA’s creditors, any payments or distributions that would otherwise be paid to holders of senior debt securities or subordinated debt securities and that are made to holders of junior subordinated debt securities because of this subrogation will be deemed a payment by RGA on account of senior indebtedness and not on account of junior subordinated debt securities. (Section 16.7 of the junior subordinated indenture).

The junior subordinated indenture provides that the foregoing subordination provisions may be changed, except in a manner which would be adverse to the holders of junior subordinated debt securities of any series

18

then outstanding. (Sections 10.1 and 10.2 of the junior subordinated indenture). The prospectus supplement or other offering materials relating to such junior subordinated debt securities would describe any such change.

The prospectus supplement or other offering materials delivered in connection with the offering of a series of subordinated debt or junior subordinated debt securities will set forth a more detailed description of the subordination provisions applicable to any such debt securities.

If this prospectus is being delivered in connection with the offering of a series of subordinated or junior subordinated debt securities, the accompanying prospectus supplement or other offering materials or information incorporated by reference will set forth the approximate amount of indebtedness senior to such subordinated or junior subordinated indebtedness outstanding as of a recent date. The indenture and the junior subordinated indenture place no limitation on the amount of additional senior indebtedness that may be incurred by RGA. RGA expects from time to time to incur additional indebtedness constituting senior indebtedness. See “—General” on page 11 for a summary of our indebtedness at March 31, 2017.

Events of Default

Unless otherwise indicated in the applicable prospectus supplement or other offering material, an event of default with respect to any series of debt securities issued under each of the indentures means:

Within 90 days after a default in respect of any series of debt securities, the trustee, or property trustee, if applicable, must give to the holders of such series notice of all uncured and unwaived defaults by us known to it. However, except in the case of default in payment, the trustee may withhold such notice if it determines that such withholding is in the interest of such holders. (Section 6.2 of each indenture).

If an event of default occurs in respect of any outstanding series of debt securities and is continuing, the trustee under the indenture, the property trustee under the junior subordinated indenture or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount, or, if the debt securities of that series are original issue discount securities or indexed securities, such portion of the principal amount as may be specified in the terms of those securities, of all of the debt securities of that series to be due and payable immediately by written notice thereof to us, and to the trustee or property trustee, if applicable, if given by the holders of the debt securities. Upon any such declaration, such principal or specified amount plus accrued and unpaid interest, and premium, if payable, will become immediately due and payable. However, with respect to any debt securities issued under the junior subordinated indenture, the payment of principal and interest on such debt securities shall remain subordinated to the extent provided in Article XVI of the junior subordinated indenture. In addition, at any time after such a declaration of acceleration but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in principal

19

amount of outstanding debt securities of that series may, subject to specified conditions, rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal, or premium, if any, or interest on debt securities of such series have been cured or waived as provided in the indenture. (Section 5.2 of each indenture).

The holders of a majority in principal amount of the outstanding debt securities of a series, on behalf of the holders of all debt securities of that series, may waive any past default and its consequences, except that they may not waive an uncured default in payment or a default which cannot be waived without the consent of the holders of all outstanding securities of that series; provided that the holders of a majority in principal amount of outstanding debt securities may rescind and annul a declaration of acceleration, as described above. (Section 5.13 of each indenture).

Within four months after the close of each fiscal year, we must file with the trustee a statement, signed by specified officers, stating whether or not such officers have knowledge of any default under the indenture and, if so, specifying each such default and the nature and status of each such default. (Section 11.2 of each indenture).

Subject to provisions in the applicable indenture relating to its duties in case of default, the trustee, or property trustee, if applicable, is not required to take action at the request of any holders of debt securities, unless such holders have offered to the trustee security or indemnity reasonably satisfactory to it. (Section 6.3 of each indenture).

Subject to such indemnification requirements and other limitations set forth in the applicable indenture, if any event of default has occurred, the holders of a majority in principal amount of the outstanding debt securities of any series may direct the time, method and place of conducting proceedings for remedies available to the trustee, or exercising any trust or power conferred on the trustee, in respect of such series. (Section 5.12 of each indenture).

Defeasance; Satisfaction and Discharge

Legal or Covenant Defeasance. Each indenture provides that we may be discharged from our obligations in respect of the debt securities of any series, as described below. These provisions will apply to any debt securities, unless otherwise specified in a prospectus supplement or other offering material. The prospectus supplement or other offering material will describe any defeasance provisions that apply to other types of debt securities. (Section 14.1 of each indenture).

At our option, we may choose either one of the following alternatives:

In either case, we will be so discharged upon the deposit with the trustee, in trust, of money and/or U.S. Government Obligations that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants to pay and discharge each installment of principal, including any mandatory sinking fund payments,

20

premium, if any, and interest on the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities. This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel or an Internal Revenue Service ruling to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance. (Section 14.2 of each indenture).

In addition, with respect to the junior subordinated indenture, in order to be discharged, no event or condition shall exist that, pursuant to certain provisions described under “— Subordination” above, would prevent us from making payments of principal of, and premium, if any, and interest on junior subordinated debt securities at the date of the irrevocable deposit referred to above. (Section 14.2 of the junior subordinated indenture).

Covenant Defeasance and Events of Default. In the event we exercise our option to effect covenant defeasance with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amount of money and/or U.S. Government Obligations on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. However, we will remain liable for those payments.

“U.S. Government Obligations” means securities which are (1) direct obligations of the United States for the payment of which its full faith and credit is pledged, or (2) obligations of a person controlled or supervised by and acting as an agency or instrumentality of the United States, the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States, which, in either case, are not callable or redeemable at the option of the issuer thereof, and will also include a depository receipt issued by a bank or trust company as custodian with respect to any such U.S. Government Obligation or a specific payment of interest on or principal of any such U.S. Government Obligation held by such custodian for the account of the holder of a depository receipt, provided that, except as required by law, such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of interest on or principal of the U.S. Government Obligation evidenced by such depository receipt. (Section 14.2 of each indenture).

We may exercise our legal defeasance option even if we have already exercised our covenant defeasance option. (Section 14.2 of each indenture).

There may be additional provisions relating to defeasance which we will describe in the prospectus supplement or other offering material. (Section 14.1 of each indenture).

Conversion or Exchange

Any series of the senior or subordinated debt securities may be convertible or exchangeable into common or preferred stock or other debt securities registered under the registration statement relating to this prospectus. The specific terms and conditions on which such debt securities may be so converted or exchanged will be set forth in the applicable prospectus supplement or other offering material. Those terms may include the conversion or exchange price, provisions for conversion or exchange, either mandatory, at the option of the holder, or at our option, whether we have an option to convert debt securities into cash, rather than common stock, and provisions under which the number of shares of common or preferred stock or other securities to be received by the holders of debt securities would be calculated as of a time and in the manner stated in the applicable prospectus supplement. (Section 15.1 of each indenture).

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York. (Section 1.11 of each indenture).

21

Regarding the Trustee

Unless otherwise specified in the applicable prospectus supplement or other offering material, The Bank of New York Mellon Trust Company, N.A. will be the trustee under the indenture and the junior subordinated indenture relating to the junior subordinated debt securities which may be offered to the RGA trusts. We have entered, and from time to time may continue to enter, into banking or other relationships with such trustees or their affiliates, including The Bank of New York Mellon. For example, The Bank of New York Mellon Trust Company, N.A. is successor trustee of the indentures relating to our 6.45% Senior Notes due 2019, our 5.00% Senior Notes due 2021, and our Variable Rate Junior Subordinated Debentures due 2065 and is trustee of the indenture relating to our 6.20% Fixed-to-Floating Rate Subordinated Debentures due 2042, our 4.70% Senior Notes due 2023, our 3.95% Senior Notes due 2026, and our 5.75% Fixed-To-Floating Rate Subordinated Debentures due 2056. The Bank of New York Mellon is a lender under our syndicated revolving credit facility, dated September 25, 2014. These entities and their affiliates also provide other banking and financial services to us.

If the trustee is or becomes one of our creditors, the indenture limits the right of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claims as security or otherwise. The trustee will be permitted to engage in other transactions. However, if after a specified default has occurred and is continuing, it acquires or has a conflicting interest (such as continuing to serve as trustee with respect to outstanding notes or debentures or continuing to be a creditor of RGA in certain circumstances), it must eliminate such conflict within 90 days or receive permission from the SEC to continue as a trustee or resign.

There may be more than one trustee under each indenture, each with respect to one or more series of debt securities. (Section 1.1 of each indenture). Any trustee may resign or be removed with respect to one or more series of debt securities, and a successor trustee may be appointed to act with respect to such series. (Section 6.10 of each indenture).

If two or more persons are acting as trustee with respect to different series of debt securities, each trustee will be a trustee of a trust under the indenture separate from the trust administered by any other such trustee. Except as otherwise indicated in this prospectus, any action to be taken by the trustee may be taken by each such trustee with respect to, and only with respect to, the one or more series of debt securities for which it is trustee under the indenture.

DESCRIPTION OF CAPITAL STOCK OF RGA

The following is a summary of the material terms of our capital stock and the provisions of our amended and restated articles of incorporation and bylaws. It also summarizes some relevant provisions of the Missouri General and Business Corporation Law, which we refer to as Missouri law. Since the terms of our articles of incorporation, and bylaws, and Missouri law, are more detailed than the general information provided below, you should only rely on the actual provisions of those documents and Missouri law. If you would like to read those documents, they are on file with the SEC, as described under the heading “Where You Can Find More Information” on page 2.

General

RGA’s authorized capital stock consists of 150 million shares of capital stock, of which:

As of March 31, 2017, RGA had approximately 64.4 million shares of common stock outstanding, and approximately 14.7 million shares issuable upon exercise or settlement of outstanding options or other awards.

22

The outstanding shares of common stock are validly issued, fully paid and nonassessable.

Common Stock

Subject to the prior rights of the holders of any shares of preferred stock which later may be issued and outstanding, holders of common stock are entitled to receive dividends as and when declared by us out of legally available funds, and, if we liquidate, dissolve, or wind up RGA, to share ratably in all remaining assets after we pay liabilities. We are prohibited from paying dividends under our credit agreement unless, at the time of declaration and payment, certain defaults would not exist under such agreement. Under certain circumstances, we may be contractually prohibited from paying dividends on our common stock due to restrictions associated with certain of our debt securities. Each holder of common stock is entitled to one vote for each share held of record on all matters presented to a vote of shareholders, including the election of directors. Holders of common stock have no cumulative voting rights or preemptive rights to purchase or subscribe for any stock or other securities and there are no conversion rights or redemption or sinking fund provisions for the common stock.

We may issue additional shares of authorized common stock without shareholder approval, subject to applicable rules of the New York Stock Exchange.

Computershare, P.O. Box 30170, College Station, TX 77842-3170, is the registrar and transfer agent for our common stock. Our common stock is listed on the New York Stock Exchange under the symbol “RGA”.

Preferred Stock

Our articles of incorporation vest our board of directors with authority to issue up to 10,000,000 shares of preferred stock from time to time in one or more series, with such voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, as may be stated in the resolution or resolutions providing for the issuance of such stock adopted from time to time by the board of directors. Our board of directors is expressly authorized to fix or determine:

23

All shares of the same series of preferred stock will be identical and of equal rank except as to the times from which cumulative dividends, if any, on those shares will be cumulative. The shares of different series may differ, including as to rank, as may be provided in our articles of incorporation, or as may be fixed by our board of directors as described above. We may from time to time amend our articles of incorporation to increase or decrease the number of authorized shares of preferred stock.

The material terms of any series of preferred stock being offered by us will be described in the prospectus supplement or other offering material relating to that series of preferred stock. If so indicated in the prospectus supplement or other offering material and if permitted by the articles of incorporation and by law, the terms of any such series may differ from the terms set forth below. That prospectus supplement may not restate the amendment to our articles of incorporation or the board resolution that establishes a particular series of preferred stock in its entirety. We urge you to read that amendment or board resolution because it, and not the description in the prospectus supplement or other offering material, will define your rights as a holder of preferred stock. The certificate of amendment to our articles of incorporation or board resolution will be filed with the Secretary of State of the State of Missouri and with the SEC.

Dividend Rights. One or more series of preferred stock may be preferred as to payment of dividends over our common stock or any other stock ranking junior to the preferred stock as to dividends. In that case, before any dividends or distributions on our common stock or stock of junior rank, other than dividends or distributions payable in common stock, are declared and set apart for payment or paid, the holders of shares of each series of preferred stock will be entitled to receive dividends when, as and if declared by our board of directors. We will pay those dividends either in cash, shares of common stock or preferred stock or otherwise, at the rate and on the date or dates indicated in the applicable prospectus supplement. With respect to each series of preferred stock entitled to cumulative dividends, the dividends on each share of that series will be cumulative from the date of issue of the share unless some other date is set forth in the prospectus supplement relating to the series. Accruals of dividends will not bear interest. We are prohibited from paying dividends under our credit agreement unless, at the time of declaration and payment, a default would not exist under the agreement.

Rights upon Liquidation. The preferred stock may be preferred over common stock, or any other stock ranking junior to the preferred stock with respect to distribution of assets, as to our assets so that the holders of each series of preferred stock will be entitled to be paid, upon voluntary or involuntary liquidation, dissolution or winding up and before any distribution is made to the holders of common stock or stock of junior rank, the amount set forth in the applicable prospectus supplement. However, in this case the holders of preferred stock will not be entitled to any other or further payment. If upon any liquidation, dissolution or winding up our net assets are insufficient to permit the payment in full of the respective amounts to which the holders of all outstanding preferred stock are entitled, our entire remaining net assets will be distributed among the holders of each series of preferred stock in an amount proportional to the full amounts to which the holders of each series are entitled.

Redemption. All shares of any series of preferred stock will be redeemable, if at all, to the extent set forth in the prospectus supplement or other offering material relating to the series.

Conversion or Exchange. Shares of any series of preferred stock will be convertible into or exchangeable for shares of common stock or preferred stock or other securities, if at all, to the extent set forth in the applicable prospectus supplement or other offering material.

Preemptive Rights. No holder of shares of any series of preferred stock will have any preemptive or preferential rights to subscribe to or purchase shares of any class or series of stock, now or hereafter authorized, or any securities convertible into, or warrants or other evidences of optional rights to purchase or subscribe to, shares of any series, now or hereafter authorized.

Voting Rights. Except as indicated in the applicable prospectus supplement or other offering material and subject to provisions in our articles of incorporation relating to the rights of our common stock, the holders of

24

voting preferred stock will be entitled to one vote for each share of preferred stock held by them on all matters properly presented to shareholders. Except as otherwise provided in the amendment to our articles of incorporation or the directors resolution that creates a specified class of preferred stock, the holders of common stock and the holders of all series of preferred stock will vote together as one class. In addition, currently under Missouri law, even if shares of a particular class or series of stock are not otherwise entitled to a vote on any matters submitted to the shareholders, amendments to the articles of incorporation which adversely affect those shares require a vote of the class or series of which such shares are a part, including amendments which would:

Most of our operations are conducted through our subsidiaries, and thus our ability to pay dividends on any series of preferred stock is dependent on their financial condition, results of operations, cash requirements and other related factors. Our subsidiaries are also subject to restrictions on dividends and other distributions contained under applicable insurance laws and related regulations.

Depending upon the rights of holders of the preferred stock, an issuance of preferred stock could adversely affect holders of common stock by delaying or preventing a change of control of RGA, making removal of the management of RGA difficult, or restricting the payment of dividends and other distributions to the holders of common stock.

As described under “Description of Depositary Shares of RGA,” we may, at our option, elect to offer depositary shares evidenced by depositary receipts, each representing an interest, to be specified in the applicable prospectus supplement for the particular series of the preferred stock, in a share of the particular series of the preferred stock issued and deposited with a preferred stock depositary. All shares of preferred stock offered by this prospectus, or issuable upon conversion, exchange or exercise of securities, will, when issued, be fully paid and non-assessable.

Certain Effects of Authorized but Unissued Stock

We may issue additional shares of common stock or preferred stock without shareholder approval, subject to applicable rules of the New York Stock Exchange, for a variety of corporate purposes, including raising additional capital, corporate acquisitions, and employee benefit plans. The existence of unissued and unreserved common and preferred stock may enable us to issue shares to persons who are friendly to current management, which could discourage an attempt to obtain control of RGA through a merger, tender offer, proxy contest, or otherwise, and protect the continuity of management and possibly deprive you of opportunities to sell your shares at prices higher than the prevailing market prices. We could also use additional shares to dilute the stock ownership of persons seeking to obtain control of RGA pursuant to the operation of the rights plan or otherwise. See also “— Anti-Takeover Provisions in the RGA Articles of Incorporation and Bylaws” below.

Limitation on Liability of Directors; Indemnification

Our articles of incorporation limit the liability of our directors to RGA and its shareholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by Missouri law. Our articles of incorporation provide that RGA will indemnify each person (other than a party plaintiff suing on his own behalf or in the right of RGA) who at any time is serving or has served as a director or officer of RGA against any

25

claim, liability or expense incurred as a result of this service, or as a result of any other service on behalf of RGA, or service at the request of RGA as a director, officer, employee, member or agent of another corporation, partnership, joint venture, trust, trade or industry association or other enterprise (whether incorporated or unincorporated, for-profit or not-for-profit), to the maximum extent permitted by law. Without limiting the generality of the foregoing, RGA will indemnify any such person who was or is a party (other than a party plaintiff suing on his own behalf or in the right of RGA), or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including, but not limited to, an action by or in the right of RGA) by reason of such service against expenses (including, without limitation, attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding. We have entered into indemnification agreements with our officers and directors providing for indemnification to the fullest extent permitted by law.

The inclusion of these provisions in our articles of incorporation may have the effect of reducing the likelihood of derivative litigation against our directors and may discourage or deter RGA or its shareholders from bringing a lawsuit against our directors for breach of their duty of care, even though such an action, if successful, might otherwise have benefited RGA and its shareholders.

Anti-Takeover Provisions in the RGA Articles of Incorporation and Bylaws

Some of the provisions in our articles of incorporation and bylaws and Section 351.459 of the Missouri corporation statute could have the following effects, among others:

The following is a summary of some of the provisions in our articles of incorporation and bylaws that could have the effects described above.

Classified Board of Directors. Our articles of incorporation and bylaws provide that our board of directors will be divided into three classes of directors serving staggered three-year terms. Each class, to the extent possible, will be equal in number. The size of our board of directors will not be less than three and our board of directors can amend the number of directors by majority vote. Each class holds office until the third annual shareholders’ meeting for election of directors following the most recent election of such class.

Directors, and Not Shareholders, Fix the Size of the Board of Directors of RGA. Our articles of incorporation and bylaws provide that the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by a majority of our board of directors, but in no event will it consist of less than three directors. In accordance with our bylaws, our board of directors currently has fixed the number of directors at eleven.

Directors are Removed for Cause Only. Missouri law provides that, unless a corporation’s articles of incorporation provide otherwise, the holders of a majority of the corporation’s voting stock may remove any director from office. Our articles of incorporation provide that shareholders may remove a director only “for cause” and with the approval of the holders of 85% of RGA’s voting stock. Our board of directors may remove a director, with or without cause, only in the event the director fails to meet the qualifications stated in the bylaws for election as a director or in the event the director is in breach of any agreement between such director and RGA relating to such director’s service as RGA’s director or employee.

26

Board Vacancies to Be Filled by Remaining Directors and Not Shareholders. Any vacancy created by any reason prior to the expiration of the class in which the vacancy occurs will be filled by a majority of the remaining directors, even if less than a quorum. A director elected to fill a vacancy will be elected for the unexpired term of his predecessor. Any directorship to be filled by reason of an increase in the number of directors may be filled by the board of directors and will be added to such class of directors so that all classes of directors will be as nearly equal in number as possible.

Shareholders May Only Act by Written Consent Upon Unanimous Written Consent. As required by Missouri law, our articles of incorporation and bylaws provide for shareholder action by unanimous written consent only.

No Special Meetings Called by Shareholders. Our articles of incorporation provide that special meetings may only be called by the chairman of our board of directors, our president, or a majority of our board of directors. Only such business will be conducted, and only such proposals acted upon, as are specified in the notice of the special meeting.

Advance Notice for Shareholder Proposals and Director Nominations. Our articles of incorporation contain provisions requiring that advance notice be delivered to RGA of any business to be brought by a shareholder before an annual meeting and providing for procedures to be followed by shareholders in nominating persons for election to our board of directors. Ordinarily, the shareholder must give notice at least 60 days but not more than 90 days before the meeting, but if we give less than 70 days’ notice of the meeting, then the shareholder must give notice within ten days after we mail notice of the meeting or make other public disclosure of the meeting. The notice must include a description of the proposal, the reasons for the proposal, and other specified matters. Additionally, our bylaws supplement the advance notice requirements included in our articles of incorporation by, among other things, requiring shareholder proponents to disclose all ownership interests in us, certain information about proposed director nominees, any material interest of the shareholder proponent or beneficial owner in the business proposed for the meeting. The bylaws also require that these disclosures be updated and supplemented, if necessary and that the shareholder proposing business or making a nomination must appear at the meeting for the proposal to be considered. Our board may reject any proposals that have not followed these procedures or that are not a proper subject for shareholder action in accordance with the provisions of applicable law.

Bylaws May Be Amended by Directors and Not Shareholders. Our articles of incorporation provide that our bylaws may be amended only by the majority of the entire board of directors. Shareholders will not be able to amend the bylaws without first amending our articles of incorporation.

Supermajority Vote Required to Amend Specified Provisions. Our articles of incorporation provide that amendment of the following provisions requires an affirmative vote of at least 85% of the outstanding capital stock entitled to vote generally in the election of directors, voting together as a single class:

Exclusive Forum Provision. Our bylaws provide for the designation of any state court located in St. Louis County, Missouri, or the United States District Court for the Eastern District of Missouri as the exclusive forum for certain shareholder litigation such as derivative claims, breach of fiduciary duty claims, claims pursuant to the General and Business Corporation Law of Missouri, our articles of incorporation or our bylaws, claims governed by the internal affairs doctrine and actions to interpret, enforce or determine the validity of our articles of incorporation or our bylaws, unless we otherwise consent to another jurisdiction.

27

Missouri Statutory Provisions

Missouri law also contains certain provisions which may have an anti-takeover effect and otherwise discourage third parties from effecting transactions with us, including control share acquisition and business combination statutes.

Business Combination Statute. Missouri law contains a “business combination statute” which restricts certain “business combinations” between us and an “interested shareholder,” or affiliates of the interested shareholder, for a period of five years after the date of the transaction in which the person becomes an interested shareholder, unless either such transaction or the interested shareholder’s acquisition of stock is approved by our board on or before the date the interested shareholder obtains such status.

The statute also provides that, after the expiration of such initial five-year period, business combinations are prohibited for an additional five-year period unless:

A “business combination” for this purpose includes a merger or consolidation, some sales, leases, exchanges, pledges and similar dispositions of corporate assets or stock and any reclassifications or recapitalizations that generally increase the proportionate voting power of the interested shareholder. An “interested shareholder” for this purpose generally means any person who, together with his or her affiliates and associates, owns or controls 20% or more of the outstanding shares of the corporation’s voting stock.

A Missouri corporation may opt out of coverage by the business combination statute by including a provision to that effect in its governing corporate documents. We have not done so.

The business combination statute may make it more difficult for a 20% beneficial owner to effect other transactions with us and may encourage persons that seek to acquire us to negotiate with our board prior to acquiring a 20% interest. It is possible that such a provision could make it more difficult to accomplish a transaction which shareholders may otherwise deem to be in their best interest.

Control Share Acquisition Statute. Missouri also has a “control share acquisition statute” that would limit the rights of a shareholder to vote some or all of the shares that it holds, in case of a shareholder whose acquisition of shares results in that shareholder having voting power, when added to the shares previously held by such shareholder, to exercise or direct the exercise of more than a specified percentage of RGA’s outstanding stock (beginning at 20%). The statute exempts some types of acquisitions and provides a procedure for an acquiring shareholder to obtain shareholder approval to permit such shareholder to vote these shares. However, as permitted by the statute, RGA previously amended its bylaws to provide that the control share acquisition statute will not apply to control share acquisitions of RGA’s stock, but may elect to become subject to such statute by a further amendment to its bylaws.

Takeover Bid Disclosure Statute. Missouri’s “takeover bid disclosure statute” requires that, under some circumstances, before making a tender offer that would result in the offeror acquiring control of us, the offeror must file certain disclosure materials with the Commissioner of the Missouri Department of Securities.

Insurance Holding Companies Act. We are regulated in Missouri as an insurance holding company. Under the Missouri Insurance Holding Companies Act and related regulations, the acquisition of control of a domestic insurer must receive prior approval by the Missouri Department of Insurance, Financial Institutions and Professional Registration, which we refer to as the “Department.” Missouri law provides that a transaction will

28

be approved if the Department finds that the transaction would, among other things, not violate the law or be contrary to the interests of the insureds of any participating domestic insurance corporations. The Department may approve any proposed change of control subject to conditions.

DESCRIPTION OF DEPOSITARY SHARES OF RGA

The description of any deposit agreement and any related depositary shares and depositary receipts in this prospectus and in any prospectus supplement or other offering material of certain provisions are summaries of the material provisions of that deposit agreement and of the depositary shares and depositary receipts. These descriptions do not include all terms of those agreements and do not contain all of the information that you may find useful. The applicable prospectus supplement or other offering material will describe the terms of any depositary shares and depositary receipts in more detail; and we urge you to read the applicable prospectus supplement and the deposit agreement because they, and not our summaries and descriptions, will define your rights as holders of the depositary shares and depositary receipts. The applicable prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the depositary shares or depositary receipts being offered. The forms of the relevant documents will be filed with the SEC and will be available as described under the heading “Where You Can Find More Information” above.

General

We may elect to have shares of preferred stock represented by depositary shares. The shares of any series of the preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company we select. The prospectus supplement or other offering material relating to a series of depositary shares will set forth the name and address of this preferred stock depositary. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, proportionately, to all the rights, preferences and privileges of the preferred stock represented by such depositary share, including dividend, voting, redemption, conversion, exchange and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement, each of which will represent the applicable interest in a number of shares of a particular series of the preferred stock described in the applicable prospectus supplement or other offering material.

A holder of depositary shares will be entitled to receive the shares of preferred stock, but only in whole shares of preferred stock, underlying those depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the whole number of shares of preferred stock to be withdrawn, the depositary will deliver to that holder at the same time a new depositary receipt for the excess number of depositary shares.

Dividends and Other Distributions

The preferred stock depositary will distribute all cash dividends or other cash distributions in respect of the series of preferred stock represented by the depositary shares to the record holders of depositary receipts in proportion, to the extent possible, to the number of depositary shares owned by those holders. The depositary, however, will distribute only the amount that can be distributed without attributing to any depositary share a fraction of one cent, and any undistributed balance will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary receipts then outstanding.

If there is a distribution other than in cash in respect of the preferred stock, the preferred stock depositary will distribute property received by it to the record holders of depositary receipts in proportion, insofar as possible, to the number of depositary shares owned by those holders, unless the preferred stock depositary determines that it is not feasible to make such a distribution. In that case, the preferred stock depositary may, with our approval, adopt any method that it deems equitable and practicable to effect the distribution, including a public or private sale of the property and distribution of the net proceeds from the sale to the holders.

29

The amount distributed in any of the above cases will be reduced by any amount we or the preferred stock depositary are required to withhold on account of taxes.

Conversion and Exchange

If any series of preferred stock underlying the depositary shares is subject to provisions relating to its conversion or exchange as set forth in an applicable prospectus supplement or other offering material, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares evidenced by the depositary receipts pursuant to those provisions.

Redemption of Depositary Shares

If any series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the preferred stock depositary resulting from the redemption, in whole or in part, of the preferred stock held by the preferred stock depositary. Whenever we redeem a share of preferred stock held by the preferred stock depositary, the preferred stock depositary will redeem as of the same redemption date a proportionate number of depositary shares representing the shares of preferred stock that were redeemed. The redemption price per depositary share will be equal to the aggregate redemption price payable with respect to the number of shares of preferred stock underlying the depositary shares. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionately as we may determine.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the redemption price. Any funds that we deposit with the preferred stock depositary relating to depositary shares which are not redeemed by the holders of the depositary shares will be returned to us after a period of two years from the date the funds are deposited by us.

Voting

Upon receipt of notice of any meeting at which the holders of any shares of preferred stock underlying the depositary shares are entitled to vote, the preferred stock depositary will mail the information contained in the notice to the record holders of the depositary receipts. Each record holder of the depositary receipts on the record date, which will be the same date as the record date for the preferred stock, may then instruct the preferred stock depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock underlying that holder’s depositary shares. The preferred stock depositary will try to vote the number of shares of preferred stock underlying the depositary shares in accordance with the instructions, and we will agree to take all reasonable action which the preferred stock depositary deems necessary to enable the preferred stock depositary to do so. The preferred stock depositary will abstain from voting the preferred stock to the extent that it does not receive specific written instructions from holders of depositary receipts representing the preferred stock.

Record Date

Subject to the provisions of the deposit agreement, whenever:

30

Withdrawal of Preferred Stock

Upon surrender of depositary receipts at the principal office of the preferred stock depositary, upon payment of any unpaid amount due the preferred stock depositary, and subject to the terms of the deposit agreement, the owner of the depositary shares evidenced by the depositary receipts is entitled to delivery of the number of whole shares of preferred stock and all money and other property, if any, represented by the depositary shares. Partial shares of preferred stock will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the preferred stock depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of preferred stock that are withdrawn will not be entitled to deposit the shares that have been withdrawn under the deposit agreement or to receive depositary receipts.

Amendment and Termination of the Deposit Agreement

We and the preferred stock depositary may at any time agree to amend the form of depositary receipt and any provision of the deposit agreement. However, any amendment that materially and adversely alters the rights of holders of depositary shares will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by us or by the preferred stock depositary only if all outstanding shares have been redeemed or if a final distribution in respect of the underlying preferred stock has been made to the holders of the depositary shares in connection with our liquidation, dissolution or winding up.

Charges of Preferred Stock Depositary

We will pay all charges of the preferred stock depositary including charges in connection with the initial deposit of the preferred stock, the initial issuance of the depositary receipts, the distribution of information to the holders of depositary receipts with respect to matters on which preference stock is entitled to vote, withdrawals of the preferred stock by the holders of depositary receipts or redemption or conversion of the preferred stock, except for taxes (including transfer taxes, if any) and other governmental charges and any other charges expressly provided in the deposit agreement to be at the expense of holders of depositary receipts or persons depositing preferred stock.

Miscellaneous

Neither we nor the preferred stock depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond our control in performing any obligations under the deposit agreement. The obligations of the preferred stock depositary under the deposit agreement are limited to performing its duties under the agreement without negligence or bad faith. Our obligations under the deposit agreement are limited to performing our duties in good faith. Neither we nor the preferred stock depositary is obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the preferred stock depositary may rely on advice of or information from counsel, accountants or other persons that they believe to be competent and on documents that they believe to be genuine.

31

The preferred stock depositary may resign at any time or be removed by us, effective upon the acceptance by its successor of its appointment. If we have not appointed a successor preferred stock depositary and the successor depositary has not accepted its appointment within 60 days after the preferred stock depositary delivered a resignation notice to us, the preferred stock depositary may terminate the deposit agreement. See “—Amendment and Termination of the Deposit Agreement” above.

DESCRIPTION OF WARRANTS OF RGA

We may issue warrants to purchase debt or equity securities. We may issue warrants independently or as part of a unit with other securities, including, without limitation, preferred securities issued by the RGA trusts. Warrants sold with other securities as a unit may be attached to or separate from the other securities. We will issue warrants under warrant agreements to be entered into between us and a warrant agent that we will name in the applicable prospectus supplement or other offering material.

The prospectus supplement or other offering material relating to any warrants we are offering will include specific terms relating to the offering, including a description of any other securities sold together with the warrants. These terms will include some or all of the following:

Warrants issued for securities other than our debt securities, common stock, preferred stock or the preferred securities of an RGA trust will not be exercisable until at least one year from the date of sale of the warrant.

We urge you to read the applicable prospectus supplement or other offering material that will describe the material terms of the warrants we are offering under this prospectus, as well as the complete warrant agreement, including the form of warrant certificate, because they, and not our summaries and descriptions, will define your

32

rights as holders of the warrants. We will incorporate by reference into the registration statement of which this prospectus is a part the form of warrant agreement that describes the terms of the warrants we are offering from reports we file with the SEC as described under the heading “Where You Can Find More Information” above.

DESCRIPTION OF PURCHASE CONTRACTS OF RGA

We may issue purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a number or amount of debt securities, common stock, preferred stock or depositary shares or warrants or trust preferred securities of an RGA trust at a future date or dates. The price per equity security and the number of securities may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula stated in the purchase contracts. The purchase contracts may require us to make periodic payments to the holders of the purchase contracts. These payments may be unsecured or prefunded on some basis to be specified in the applicable prospectus supplement or other offering material.

The prospectus supplement or other offering material relating to any purchase contracts we are offering will specify the material terms of the purchase contracts and any applicable pledge or depository arrangements, including one or more of the following:

The contract fee may be calculated as a percentage of the stated amount of the purchase contract or otherwise.

33

We urge you to read the applicable prospectus supplement or other offering material that will describe the material terms of the purchase contracts that we are offering under this prospectus, as well as the instruments that contain the terms of any securities that are subject to those purchase contracts, because they, and not our summaries and descriptions, will define your rights as holders of the purchase contracts. Certain of those instruments, or forms of those instruments, have been filed as exhibits to the registration statement of which this prospectus is a part, and supplements to those instruments or forms may be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the SEC as described under the heading “Where You Can Find More Information” above.

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement or other offering material, we may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The prospectus supplement or other offering material will describe:

We urge you to read the applicable prospectus supplement or other offering material that will describe the material terms of the units that we are offering under this prospectus, as well as the complete instruments that contain the terms of the securities comprising the units, because they, and not our summaries and descriptions, will define your rights as holders of the units. Certain of those instruments, or forms of those instruments, have been filed as exhibits to the registration statement of which this prospectus is a part, and supplements to those instruments or forms may be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the SEC as described under the heading “Where You Can Find More Information” above.

DESCRIPTION OF PREFERRED SECURITIES OF THE RGA TRUSTS

Each RGA trust may issue, from time to time, one series of preferred securities having terms described in the prospectus supplement or other offering material. Preferred securities may be issued either independently or as part of a unit with other securities, including, without limitation, warrants to purchase common stock of RGA. Preferred securities sold with other securities as a unit may be attached to or separate from the other securities. The proceeds from the sale of each trust’s preferred and common securities will be used by such trust to purchase a series of junior subordinated debt securities issued by RGA. The junior subordinated debt securities will be held in trust by the trust’s property trustee for the benefit of the holders of such preferred and common securities. Each amended and restated trust agreement has been or will be qualified as an indenture under the Trust Indenture Act. The property trustee for each trust, The Bank of New York Mellon Trust Company, N.A., as successor to The Bank of New York, an independent trustee, will act as indenture trustee for the preferred securities for purposes of compliance with the provisions of the Trust Indenture Act. The preferred securities will have the terms, including distributions, redemption, voting, liquidation rights, maturity date or dates and the other preferred, deferred or other special rights or restrictions as are established by the administrative trustees in accordance with the applicable amended and restated trust agreement or as are set forth in the amended and restated trust agreement or made part of the amended and restated trust agreement by the Trust Indenture Act.

34

Such terms, rights and restrictions will mirror the terms of the junior subordinated debt securities held by the applicable trust and will be described in the applicable prospectus supplement or other offering material.

All preferred securities offered by the prospectus will be guaranteed by us to the extent set forth below under “Description of the Preferred Securities Guarantees of RGA.” The guarantee issued by us to each RGA trust, when taken together with our obligations under the junior subordinated debt securities issued to any RGA trust and under the applicable indenture and any applicable supplemental indentures, and our obligations under each amended and restated trust agreement, including the obligation to pay expenses of each RGA trust, will provide a full and unconditional guarantee by us of amounts due on the preferred securities issued by each RGA trust. The payment terms of the preferred securities will be the same as the junior subordinated debt securities issued to the applicable RGA trust by us.

Each amended and restated trust agreement authorizes the administrative trustees to issue on behalf of the applicable trust one series of common securities having terms, including distributions, redemption, voting and liquidation rights, and restrictions that are established by the administrative trustees in accordance with the amended and restated trust agreement or that are otherwise set forth in the amended and restated trust agreement. The terms of the common securities issued by each RGA trust will be substantially identical to the terms of the preferred securities issued by the RGA trust. The common securities will rank equally, and payments will be made proportionately, with the preferred securities of that trust. However, if an event of default under the amended and restated trust agreement of the RGA trust has occurred and is continuing, the cash distributions and liquidation, redemption and other amounts payable on the common securities will be subordinated to the preferred securities in right of payment. The common securities will also carry the right to vote and to appoint, remove or replace any of the trustees of the RGA trust. RGA will own, directly or indirectly, all of the common securities of each RGA trust.

The financial statements of any RGA trust that issues preferred securities will be reflected in our consolidated financial statements with the preferred securities shown as company-obligated mandatorily-redeemable preferred securities of a subsidiary trust under “minority interest.” We will include in a footnote to our audited consolidated financial statements, statements that the applicable RGA trust is wholly-owned by us and that the sole asset of the RGA trust is the junior subordinated debt securities, indicating the principal amount, interest rate and maturity date of the junior subordinated debt securities.

Enforcement of Certain Rights by Holders of Preferred Securities

If an event of default occurs, and is continuing, under the amended and restated trust agreement of either RGA trust, the holders of the preferred securities of that trust may rely on the property trustee to enforce its rights as a holder of the subordinated debt securities against RGA. Additionally, those who together hold a majority of the aggregate stated liquidation amount of an RGA trust’s preferred securities will have the right to:

If such a default occurs and the event is attributable to RGA’s failure to pay interest or principal on the junior subordinated debt securities when due, including any payment on redemption, and this debt payment failure is continuing, a preferred securities holder of the trust may directly institute a proceeding for the enforcement of this payment. Such a proceeding will be limited, however, to enforcing the payment of this principal or interest only up to the value of the aggregate liquidation amount of the holder’s preferred securities as determined after the due date specified in the applicable series of junior subordinated debt securities. RGA will be subrogated to the holder’s rights under the applicable amended and restated trust agreement to the extent of any payment it makes to the holder in connection with such a direct action, and RGA may set off against any such payment that it makes under the applicable preferred securities guarantee.

35

DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEES OF RGA

Set forth below is a summary of information concerning the guarantees that will be executed and delivered by us for the benefit of the holders, from time to time, of preferred securities. Summaries of any other terms of any guarantee that are issued will be set forth in the applicable prospectus supplement or other offering material. Each guarantee has been or will be qualified as an indenture under the Trust Indenture Act. Unless otherwise specified in the applicable prospectus supplement or other offering material, The Bank of New York Mellon Trust Company, N.A., as successor to The Bank of New York will act as the preferred securities guarantee trustee. The terms of each guarantee will be set forth in the guarantee and will include the terms made part of the guarantee by the Trust Indenture Act and will be available as described under the heading “Where You Can Find More Information” on page 2.

Unless otherwise specified in the applicable prospectus supplement or other offering material, we will agree, to the extent set forth in each guarantee, to pay in full to the holders of the preferred securities, the payments and distributions to be made with respect to the preferred securities, except to the extent paid by the applicable RGA trust, as and when due, regardless of any defense, right of set-off or counterclaim which the RGA trust may have or assert. The following payments or distributions with respect to the preferred securities, to the extent not paid by the RGA trust and to the extent that such RGA trust has funds available for these payments or distributions, will be subject to the guarantee:

(i) the sum of the liquidation amount and all accrued and unpaid distributions on the preferred securities to the date of payment, or

(ii) the amount of assets of the RGA trust remaining for distribution to holders of the preferred securities in liquidation of the RGA trust.

We may satisfy our obligation to make a guarantee payment by making a direct payment of the required amounts to the holders of preferred securities or by causing the applicable RGA trust to pay the amounts to the holders.

Each guarantee will not apply to any payment of distributions except to the extent the applicable RGA trust has funds available to make the payment. If we do not make interest or principal payments on the junior subordinated debt securities purchased by the RGA trust, the RGA trust will not pay distributions on the preferred securities issued by the RGA trust and will not have funds available to make the payments.

Covenants of RGA

Unless otherwise specified in the applicable prospectus supplement or other offering material, in each guarantee of the payment obligations of an RGA trust with respect to preferred securities, we will covenant that, so long as any preferred securities issued by the RGA trust remain outstanding, if there has occurred any event which would constitute an event of default under the guarantee or under the amended and restated trust agreement of the RGA trust, then RGA will not:

(1) dividends or distribution of shares of common stock of RGA;

36

(2) any declaration of a non-cash dividend in connection with the implementation of a shareholder rights plan, or the issuance of stock under any such plan in the future, or the redemption or repurchase of any such rights outstanding under a shareholder rights plan; or

(3) purchases of common stock of RGA related to the rights under any of RGA’s benefits plans for its directors, officers or employees;

Modification of the Guarantees; Assignment

Except for any changes that do not adversely affect the rights of holders of preferred securities, in which case no consent of the holders will be required, each guarantee of the payment obligations of an RGA trust with respect to preferred securities may be amended only with the prior approval of the holders of at least a majority in aggregate liquidation amount of the outstanding preferred securities of the RGA trust. The manner of obtaining any approval of holders of the preferred securities will be set forth in an accompanying prospectus supplement. All guarantees and agreements contained in a guarantee of the obligations of an RGA trust with respect to preferred securities will bind the successors, assigns, receivers, trustees and representatives of RGA and will inure to the benefit of the holders of the preferred securities of the applicable RGA trust then outstanding.

Events of Default

An event of default under a preferred securities guarantee will occur upon our failure to perform any of our payment or other obligations under the guarantee. The holders of a majority in aggregate liquidation amount of the preferred securities to which the preferred securities guarantee relates will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the preferred securities guarantee trustee with respect to the guarantee or to direct the exercise of any trust or power conferred upon the preferred securities guarantee trustee under the guarantee.

If we have failed to make a guarantee payment under a guarantee, a record holder of preferred securities to which the guarantee relates may directly institute a proceeding against us for enforcement of the guarantee for the payment to the record holder of the preferred securities to which the guarantee relates of the principal of or interest on the applicable subordinated debt securities on or after the respective due dates specified in the junior subordinated debt securities, and the amount of the payment will be based on the holder’s proportionate share of the amount due and owing on all of the preferred securities to which the guarantee relates. We have waived any right or remedy to require that any action be brought first against the applicable RGA trust or any other person or entity before proceeding directly against us. The record holder in the case of the issuance of one or more global preferred securities certificates will be The Depository Trust Company, or its nominee, acting at the direction of the beneficial owners of the preferred securities.

We will be required to provide annually to the preferred securities guarantee trustee a statement as to the performance of our obligations under each outstanding preferred securities guarantee and as to any default in our performance.

37

Termination

Each preferred securities guarantee will terminate as to the preferred securities issued by the applicable RGA trust:

Each preferred securities guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of preferred securities issued by the applicable RGA trust must restore payment of any sums paid under the preferred securities or the preferred securities guarantee.

Status of the Guarantees

The preferred securities guarantees will constitute our unsecured obligations and, unless otherwise indicated in an applicable prospectus supplement or other offering material, will rank as follows:

(1) the most senior preferred or preference stock now or hereafter issued by us and with any guarantee now or hereafter entered into by us in respect of any preferred or preference stock of any of our affiliates;

(2) the applicable junior subordinated debt securities; and

(3) any other liabilities or obligations made equivalent by their terms; and

The terms of the preferred securities provide that each holder of preferred securities by acceptance of the preferred securities agrees to the subordination provisions and other terms of our guarantee relating to the preferred securities.

Each preferred securities guarantee will constitute a guarantee of payment and not of collection. This means that the guaranteed party may institute a legal proceeding directly against us to enforce its rights under the guarantee without instituting a legal proceeding against any other person or entity.

Information Concerning the Preferred Securities Guarantee Trustee

The preferred securities guarantee trustee, before the occurrence of a default under a preferred securities guarantee, undertakes to perform only the duties that are specifically set forth in the guarantee and, after a default under a guarantee, will exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. Subject to this provision, the preferred securities guarantee trustee is under no obligation to exercise any of the powers vested in it by a preferred securities guarantee at the request of any holder of preferred securities to which the guarantee relates unless it is offered reasonable indemnity against the costs, expenses and liabilities that might be incurred by the preferred securities guarantee trustee in exercising any of its powers; but the foregoing shall not relieve the trustee, upon the occurrence of an event of default under such guarantee, from exercising the rights and powers vested in it by such guarantee.

38

Expense Agreement

We will, pursuant to an agreement as to expenses and liabilities entered into by us and each RGA trust under its amended and restated trust agreement, irrevocably and unconditionally guarantee to each person or entity to whom the trust becomes indebted or liable, the full payment of any costs, expenses or liabilities of the trust, other than obligations of the trust to pay to the holders of the preferred securities or other similar interests in the trust the amounts due to the holders pursuant to the terms of the preferred securities or other similar interests, as the case may be. Third party creditors of the trust may proceed directly against us under the expense agreement, regardless of whether they had notice of the expense agreement.

Governing Law

The preferred securities guarantees will be governed by and construed in accordance with the internal laws of the State of New York.

EFFECT OF OBLIGATIONS UNDER THE JUNIOR SUBORDINATED DEBT SECURITIES AND

THE PREFERRED SECURITIES GUARANTEES

As set forth in the amended and restated trust agreements of each RGA trust, the sole purpose of the RGA trusts is to issue the preferred securities and common securities evidencing undivided beneficial interests in the assets of each of the trusts, and to invest the proceeds from such issuance and sale in RGA’s junior subordinated debt securities.

As long as payments of interest and other payments are made when due on the junior subordinated debt securities held by the RGA trusts, such payments will be sufficient to cover distributions and payments due on the preferred securities and common securities because of the following factors:

Payments of distributions, to the extent funds for such payments are available, and other payments due on the preferred securities, to the extent funds for such payments are available, are guaranteed by RGA as and to the extent set forth under “Description of the Preferred Securities Guarantees of RGA.” If RGA does not make interest payments on the junior subordinated debt securities purchased by the applicable trust, it is expected that the applicable trust will not have sufficient funds to pay distributions on the preferred securities and the preferred securities guarantee will not apply, since the preferred securities guarantee covers the payment of distributions and other payments on the preferred securities only if and to the extent that RGA has made a payment of interest or principal on the junior subordinated debt securities held by the applicable trust as its sole asset. However, the preferred securities guarantee, when taken together with RGA’s obligations under the junior subordinated debt securities and the junior subordinated indenture and its obligations under the respective amended and restated trust agreements, including its obligations to pay costs, expenses, debts and liabilities of the trust, other than with respect to the preferred securities and common securities, provide a full and unconditional guarantee, on a subordinated basis, by RGA of amounts due on the preferred securities.

39

If RGA fails to make interest or other payments on the junior subordinated debt securities when due, taking account of any extension period, the amended and restated trust agreement provides a mechanism whereby the holders of the preferred securities affected thereby, using the procedures described in any accompanying prospectus supplement, may direct the property trustee to enforce its rights under the junior subordinated debt securities. If a debt payment failure has occurred and is continuing, a holder of preferred securities may institute a direct action for payment after the respective due date specified in the junior subordinated debt securities. In connection with such direct action, RGA will be subrogated to the rights of such holder of preferred securities under the amended and restated trust agreement to the extent of any payment made by RGA to such holder of preferred securities in such direct action. RGA, under the guarantee, acknowledges that the guarantee trustee shall enforce the guarantee on behalf of the holders of the preferred securities. If RGA fails to make payments under the guarantee, the guarantee provides a mechanism whereby the holders of the preferred securities may direct the trustee to enforce its rights thereunder. Any holder of preferred securities may institute a legal proceeding directly against RGA to enforce the guarantee trustee’s rights under the guarantee without first instituting a legal proceeding against the trust, the guarantee trustee, or any other person or entity.

RGA and each of the RGA trusts believe that the above mechanisms and obligations, taken together, provide a full and unconditional guarantee by RGA on a subordinated basis of payments due on the preferred securities. See “Description of the Preferred Securities Guarantees of RGA,” beginning on page 36.

Upon any voluntary or involuntary termination, winding-up or liquidation of an RGA trust involving the liquidation of the junior subordinated debt securities, the holders of the preferred securities will be entitled to receive, out of assets held by such RGA trust, the liquidation distribution in cash. Upon our voluntary or involuntary liquidation or bankruptcy, the property trustee, as holder of the junior subordinated debt securities, would be a subordinated creditor of ours. Therefore, the property trustee would be subordinated in right of payment to all of our senior and subordinated debt, but is entitled to receive payment in full of principal and interest before any of our shareholders receive payments or distributions. Since we are the guarantor under the preferred securities guarantees and have agreed to pay for all costs, expenses and liabilities of the RGA trusts other than the obligations of the trusts to pay to holders of the preferred securities the amounts due to the holders pursuant to the terms of the preferred securities, the positions of a holder of the preferred securities and a holder of the junior subordinated debt securities relative to our other creditors and to our shareholders in the event of liquidation or bankruptcy are expected to be substantially the same.

PLAN OF DISTRIBUTION

We, any RGA trust, or any selling security holder may offer or sell these securities to or through one or more underwriters, dealers and agents, or through a combination of any of these methods, or directly to purchasers, on a continuous or delayed basis. We will describe the details of any such offering and the plan of distribution for any securities offering by us, any RGA trust or any selling security holder in a supplement to this prospectus or other offering material.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

40

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, William L. Hutton, Esq., Executive Vice President, General Counsel and Secretary of RGA, will issue an opinion about the legality of the common stock issued by us, as well as the preferred stock, depositary shares, warrants, purchase contracts and units of RGA under Missouri law, and Bryan Cave LLP will issue an opinion about the legality of the debt securities of RGA and the preferred securities guarantees of RGA. Mr. Hutton is paid a salary and bonus by RGA, participates in certain employee benefit plans of RGA and beneficially owns shares of Common Stock, performance contingent share units and stock appreciation rights. Unless otherwise indicated in the applicable prospectus supplement, Richards, Layton & Finger, P.A., our special Delaware counsel, will issue an opinion about the legality of the trust preferred securities.
