The calculation of common equivalent shares does not include the impact of options having a strike or conversion price that exceeds the average stock price for the earnings period, as the result would be antidilutive. The calculation of common equivalent shares also excludes the impact of outstanding performance contingent shares, as the conditions necessary for their issuance have not been satisfied as of the end of the reporting period. For the three months ended September 30, 20162017, no0.1 million stock options and approximately 0.70.3 million performance contingent shares were excluded from the calculation. For the three months ended September 30, 20152016, no stock options and approximately 0.7 million performance contingent shares were excluded from the calculation. Year-to-date amounts for equivalent shares from outstanding stock options and performance contingent shares are the weighted average of the individual quarterly amounts.

The Company enters into various collateral arrangements with counterparties that require both the pledging and acceptance of fixed maturity securities as collateral. Pledged fixed maturity securities are included in fixed maturity securities, available-for-sale in the condensed consolidated balance sheets. Fixed maturity securities received as collateral are held in separate custodial accounts and are not recorded on the Company’s condensed consolidated balance sheets. Subject to certain constraints, the Company is permitted by contract to sell or repledge collateral it receives; however, as of September 30, 20162017 and December 31, 20152016, none of the collateral received had been sold or repledged. The Company also holds assets in trust to satisfy collateral requirements under certain third-party reinsurance treaties. The following table includes fixed maturity securities pledged and received as collateral and assets in trust held to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties as of September 30, 20162017 and December 31, 20152016 (dollars in thousands):

Other-Than-Temporary Impairments - Fixed Maturity and Equity Securities
As discussed in Note 2 – “Summary of Significant Accounting Policies” of the 20152016 Annual Report, a portion of certain other-than-temporary impairment (“OTTI”) losses on fixed maturity securities is recognized in AOCI. For these securities, the net amount recognized in the condensed consolidated statements of income (“credit loss impairments”) represents the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. Any remaining difference between the fair value and amortized cost is recognized in AOCI. The following table sets forth the amount of pre-tax credit loss impairments on fixed maturity securities held by the Company as of the dates indicated, for which a portion of the OTTI loss was recognized in AOCI, and the corresponding changes in such amounts (dollars in thousands):

The Company’s determination of whether a decline in value is other-than-temporary includes analysis of the underlying credit and the extent and duration of a decline in value. The Company’s credit analysis of an investment includes determining whether the issuer is current on its contractual payments, evaluating whether it is probable that the Company will be able to collect all amounts due according to the contractual terms of the security and analyzing the overall ability of the Company to recover the amortized cost of the investment. In the Company’s impairment review process, the duration and severity of an unrealized loss position for equity securities are given greater weight and consideration given the lack of contractual cash flows or deferability features.
The following tables present the estimated fair values and gross unrealized losses, including other-than-temporary impairment losses reported in AOCI, for 7551,165 and 2,0801,535 fixed maturity and equity securities that have estimated fair values below amortized cost as of September 30, 20162017 and December 31, 20152016, respectively (dollars in thousands). These investments are presented by class and grade of security, as well as the length of time the related fair value has remained below amortized cost.

The Company did not acquire any impaired mortgage loans during the nine months ended September 30, 20162017 and 2015.2016. The Company had no mortgage loans that were on a nonaccrual status at September 30, 20162017 and December 31, 20152016.
Policy Loans
Policy loans comprised approximately 3.1%2.7% and 3.5%3.2% of the Company’s total investments as of September 30, 20162017 and December 31, 20152016, respectively, the majority of which are associated with one client. These policy loans present no credit risk because the amount of the loan cannot exceed the obligation due to the ceding company upon the death of the insured or surrender of the underlying policy. The provisions of the treaties in force and the underlying policies determine the policy loan interest rates. The Company earns a spread between the interest rate earned on policy loans and the interest rate credited to corresponding liabilities.
Funds Withheld at Interest
Funds withheld at interest comprised approximately 12.8%12.1% and 14.0%13.1% of the Company’s total investments as of September 30, 20162017 and December 31, 20152016, respectively. Of the $5.9$6.0 billion funds withheld at interest balance, net of embedded derivatives, as of September 30, 2016,2017, $4.0 billion of the balance is associated with one client. For reinsurance agreements written on a modified coinsurance basis and certain agreements written on a coinsurance funds withheld basis, assets equal to the net statutory reserves are withheld and legally owned and managed by the ceding company and are reflected as funds withheld at interest on the Company’s condensed consolidated balance sheets. In the event of a ceding company’s insolvency, the Company would need to assert a claim on the assets supporting its reserve liabilities. However, the risk of loss to the Company is mitigated by its ability to offset amounts it owes the ceding company for claims or allowances against amounts owed to the Company from the ceding company.

Accounting for Derivative Instruments and Hedging Activities
The Company does not enter into derivative instruments for speculative purposes. As discussed below under “Non-qualifying Derivatives and Derivatives for Purposes Other Than Hedging,” the Company uses various derivative instruments for risk management purposes that either do not qualify or have not been qualified for hedge accounting treatment, including derivatives used to economically hedge changes in the fair value of liabilities associated with the reinsurance of variable annuities with guaranteed living benefits.treatment. As of September 30, 20162017 and December 31, 20152016, the Company held interest rate swaps that were designated and qualified as cash flow hedges of interest rate risk, for variable rate liabilities and foreign currency assets, foreign currency swaps and foreign currency forwards that were designated and qualified as hedges of a portion of its net investment in its foreign operations, foreign currency swaps that were designated and qualified as fair value hedges of foreign currency risk, and derivative instruments that were not designated as hedging instruments. See Note 2 – “Summary of Significant Accounting Policies” of the Company’s 20152016 Annual Report for a detailed discussion of the accounting treatment for derivative instruments, including embedded derivatives. Derivative instruments are carried at fair value and generally require an insignificant amount of cash at inception of the contracts.
Fair Value Hedges
The Company designates and reports certain foreign currency swaps to hedge the foreign currency fair value exposure of foreign currency denominated assets as fair value hedges when they meet the requirements of the general accounting principles for Derivatives and Hedging. The gain or loss on the hedged item attributable to a change in foreign currency and the offsetting gain or loss on the related foreign currency swaps as of September 30, 2017 and 2016, were (dollars in thousands):

A regression analysis was used, both at inception of the hedge and on an ongoing basis, to determine whether each derivative used in a hedged transaction is highly effective in offsetting changes in the hedged item. For the foreign currency swaps, the change in fair value related to changes in the benchmark interest rate and credit spreads are excluded from the hedge effectiveness. For the three and nine months ended September 30, 2016, $1.62017, $0.2 million and $(5.4)$0.8 million, respectively, of the change in the estimated fair value of derivatives, was excluded from hedge effectiveness. For the three and nine months ended September 30, 2015, $2.12016, $1.6 million and $(5.4) million, respectively, of the change in the estimated fair value of derivatives, was excluded from hedge effectiveness.

Cash Flow Hedges
Certain derivative instruments are designated as cash flow hedges when they meet the requirements of the general accounting principles for Derivatives and Hedging.Hedging. The Company designates and accounts for the following as cash flow hedges:flows: (i) certain interest rate swaps, in which the cash flows of liabilities are variable based on a benchmark rate; (ii) certain interest rate swaps, in which the cash flows of assets are denominated in different currencies, commonly referred to as cross-currency swaps; (ii) certain interest rate swaps, in which the cash flows of liabilities are variable based on a benchmark rate (LIBOR); and (iii) forward bond purchase commitments.

As of September 30, 2016,2017, the before-tax deferred net gains (losses) on derivative instruments recorded in AOCI that are expected to be reclassified to earnings during the next twelve months are approximately $0.6 million.$(0.4) million. This expectation is based on the anticipated interest payments on hedged investments in fixed maturity securities that will occur over the next twelve months, at which time the Company will recognize the deferred net gains (losses) as an adjustment to investment income over the term of the investment cash flows.

All components of each derivative'sderivative’s gain or loss were included in the assessment of hedge effectiveness. For the three and nine months ended September 30, 20162017 and 2015,2016, the ineffective portion of derivatives reported as cash flow hedges was not material to the Company'sCompany’s results of operations. Also, there were no material amounts reclassified into earnings relating to instances in which the Company discontinued cash flow hedge accounting because the forecasted transaction did not occur by the anticipated date or within the additional time period permitted by the authoritative guidance for the accounting for derivatives and hedging.

Hedges of Net Investments in Foreign Operations
The Company uses foreign currency swaps and foreign currency forwards to hedge a portion of its net investment in certain foreign operations against adverse movements in exchange rates. The following table illustrates the Company’s net investments in foreign operations (“NIFO”) hedges for the three and nine months ended September 30, 20162017 and 20152016 (dollars in thousands):

(1)There were no sales or substantial liquidations of net investments in foreign operations that would have required the reclassification of gains or losses from accumulated other comprehensive income (loss) into investment income during the periods presented.
(2)There was no ineffectiveness recognized for the Company’s hedges of net investments in foreign operations.

The cumulative foreign currency translation gain recorded in AOCI related to these hedges was $148.7109.7 million and $171.9161.6 million at September 30, 20162017 and December 31, 20152016, respectively. If a hedged foreign operation was sold or substantially liquidated, the amounts in AOCI would be reclassified to the condensed consolidated statements of income. A pro rata portion would be reclassified upon partial sale of a hedged foreign operation.

Non-qualifying Derivatives and Derivatives for Purposes Other Than Hedging
The Company uses various other derivative instruments for risk management purposes that either do not qualify or have not been qualified for hedge accounting treatment. The gain or loss related to the change in fair value for these derivative instruments is recognized in investment related gains (losses), net in the condensed consolidated statements of income, except where otherwise noted.

Types of Derivatives Used by the Company
Interest Rate Swaps
Interest rate swaps are used by the Company primarily to reduce market risks from changes in interest rates, to alter interest rate exposure arising from mismatches between assets and liabilities (duration mismatches) and to manage the risk of cash flows of liabilities that are variable based on a benchmark rate (LIBOR).rate. With an interest rate swap, the Company agrees with another party to exchange, at specified intervals, the difference between two rates, which can be either fixed-rate or floating-rate interest amounts, tied to an agreed-upon notional principal amount. These transactions are executed pursuant to master agreements that provide for a single net payment or individual gross payments at each due date. The Company utilizes interest rate swaps in cash flow and non-qualifying hedging relationships.

Table of Contents


Interest Rate Options
Interest rate options, commonly referred to as swaptions, have been used by the Company primarily to hedge living benefit guarantees embedded in certain variable annuity products. A swaption, used to hedge against adverse changes in interest rates, is an option to enter into a swap with a forward starting effective date. The Company pays an upfront premium for the right to exercise this option in the future.
Financial Futures
Exchange-traded futures are used primarily to economically hedge liabilities embedded in certain variable annuity products. With exchange-traded futures transactions, the Company agrees to purchase or sell a specified number of contracts, the value of which is determined by the relevant indices, and to post variation margin on a daily basis in an amount equal to the difference between the daily estimated fair values of those contracts. The Company enters into exchange-traded futures with regulated futures commission merchants that are members of the exchange.
Equity Options
Equity index options are used by the Company primarily to hedge minimum guarantees embedded in certain variable annuity products. To hedge against adverse changes in equity indices volatility, the Company buys put options. The contracts are net settled in cash based on differentials in the indices at the time of exercise and the strike price. Equity warrants are also used by the Company to economically hedge the variability in anticipated cash flows for the acquisition of investment securities.
Consumer Price Index Swaps
Consumer price index (“CPI”) swaps are used by the Company primarily to economically hedge liabilities embedded in certain insurance products where value is directly affected by changes in a designated benchmark consumer price index. With a CPI swap transaction, the Company agrees with another party to exchange the actual amount of inflation realized over a specified period of time for a fixed amount of inflation determined at inception. These transactions are executed pursuant to master agreements that provide for a single net payment or individual gross payments to be made by the counterparty at each due date. Most of these swaps will require a single payment to be made by one counterparty at the maturity date of the swap.
Foreign Currency Swaps
Foreign currency swaps are used by the Company to reduce the risk from fluctuations in foreign currency exchange rates associated with its assets and liabilities denominated in foreign currencies. With a foreign currency swap transaction, the Company agrees with another party to exchange, at specified intervals, the difference between one currency and another at a forward exchange rate calculated by reference to an agreed upon principal amount. The principal amount of each currency is exchanged at the termination of the currency swap by each party. The Company uses foreign currency swaps to hedge a portionin hedges of its net investmentinvestments in certain foreign operations and foreign currency securities against adverse movements in exchange rates. The Company also uses foreign currency swaps tonon-qualifying hedge its exposure to market risks from changes in currency exchange rates with respect to investments denominated in foreign currencies that the Company either holds or intends to acquire or sell.relationships.
Foreign Currency Forwards
Foreign currency forwards are used by the Company to reduce the risk from fluctuations in foreign currency exchange rates associated with its assets and liabilities denominated in foreign currencies. With a foreign currency forward transaction, the Company agrees with another party to deliver a specified amount of an identified currency at a specified future date. The price is agreed upon at the time of the contract and payment for such a contract is made in a different currency at the specified future date. The Company uses foreign currency forwards in hedges of net investments in foreign operations and non-qualifying hedge relationships.
Forward Bond Purchase Commitments
Forward bond purchase commitments have been used by the Company to hedge against the variability in the anticipated cash flows required to purchase securities. With forward bond purchase commitments, the forward price is agreed upon at the time of the contract and payment for such contract is made at the future specified settlement date of the securities.

Credit Default Swaps
The Company sells protection under single name credit default swaps and credit default swap index tranches to diversify its credit risk exposure in certain portfolios and, in combination with purchasing securities, to replicate characteristics of similar investments based on the credit quality and term of the credit default swap. Credit default triggers for indexed reference entities and single name reference entities are defined in the contracts. The Company’s maximum exposure to credit loss equals the notional value for credit default swaps. In the event of default of a referencing entity, the Company is typically required to pay the protection holder the full notional value less a recovery amount determined at auction.

(3)The weighted average years to maturity of the credit default swaps is calculated based on weighted average notional amounts.
The Company also purchases credit default swaps to reduce its risk against a drop in bond prices due to credit concerns of certain bond issuers. If a credit event, as defined by the contract, occurs, the Company is able to put the bond back to the counterparty at par.
Longevity Swaps
The Company enters into longevity swaps in the form of out-of-the-money options, which provide protection against changes in mortality improvement to retirement plans and insurers of such plans. With a longevity swap transaction, the Company agrees with another party to exchange a proportion of a notional value. The proportion is determined by the difference between a predefined benefit, and the realized benefit plus the future expected benefit, calculated by reference to a population index for a fixed premium.
Mortality Swaps
Mortality swaps are used by the Company to hedge risk from changes in mortality experience associated with its reinsurance of life insurance risk. The Company agrees with another party to exchange, at specified intervals, a proportion of a notional value determined by the difference between a predefined expected and realized claim amount on a designated index of reinsured lives, for a fixed percentage (premium) each term.
Synthetic Guaranteed Investment Contracts
The Company sells fee-based synthetic guaranteed investment contracts to retirement plans which include investment-only, stable value contracts. The assets are owned by the trustees of such plans, who invest the assets under the terms of investment guidelines to which the Company agrees. The contracts contain a guarantee of a minimum rate of return on participant balances supported by the underlying assets, and a guarantee of liquidity to meet certain participant-initiated plan cash flow requirements. These contracts are reported as derivatives and recorded at fair value and classified as interest rate derivatives.value.
Embedded Derivatives
The Company has certain embedded derivatives which are required to be separated from their host contracts and reported as derivatives. Host contracts include reinsurance treaties structured on a modified coinsurance ("modco"(“modco”) or funds withheld basis. Additionally, the Company reinsures equity-indexed annuity and variable annuity contracts with benefits that are considered

embedded derivatives, including guaranteed minimum withdrawal benefits, guaranteed minimum accumulation benefits, and guaranteed minimum income benefits. The changes in fair values of embedded derivatives on equity-indexed annuities described below relate to changes in the fair value associated with capital market and other related assumptions. The Company’s utilization of a credit valuation adjustment ("CVA"(“CVA”) did not have a material effect on the change in fair value of its embedded derivatives for the three and nine months ended September 30, 20162017 and 2015.

Credit Risk
The Company manages its credit risk related to over-the-counter ("OTC"(“OTC”) derivatives by entering into transactions with creditworthy counterparties, maintaining collateral arrangements and through the use of master netting agreements that provide for a single net payment to be made by one counterparty to another at each due date and upon termination.
The credit exposure of the Company'sCompany’s OTC derivative transactions is represented by the contracts with a positive fair value (market value) at the reporting date. To reduce credit exposures, the Company seeks to (i) enter into OTC derivative transactions pursuant to master netting agreements that provide for a netting of payments and receipts with a single counterparty, and (ii) enter into agreements that allow the use of credit support annexes, which are bilateral rating-sensitive agreements that require collateral postings at established threshold levels. Certain of the Company'sCompany’s OTC derivatives are cleared derivatives, which are bilateral transactions between the Company and a counterparty where the transactions are cleared through a clearinghouse, such that each derivative counterparty is only exposed to the default of the clearinghouse. These cleared transactions require initial and daily variation margin collateral postings and include certain interest rate swaps and credit default swaps entered into on or after June 10, 2013, related to guidelines implemented under the Dodd-Frank Wall Street Reform and Consumer Protection Act. Also, the Company enters into exchange-traded futures through regulated exchanges and these transactions are settled on a daily basis, thereby reducing credit risk exposure in the event of non-performance by counterparties to such financial instruments.
The Company enters into various collateral arrangements, which require both the posting and accepting of collateral in connection with its derivative instruments. Collateral agreements contain attachment thresholds that may vary depending on the posting party’s ratings. Additionally, a decline in the Company’s or the counterparty’s credit ratings to specified levels could result in potential settlement of the derivative positions under the Company’s agreements with its counterparties. The Company also has exchange-traded futures, which require the maintenance of a margin account. As exchange-traded futures are affected through regulated exchanges, and positions are marked to market on a daily basis, the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties.

The Company’s credit exposure related to derivative contracts is generally limited to the fair value at the reporting date plus or minus any collateral posted or held by the Company. The Company’s credit exposure to mortality swaps is minimal, as they are fully collateralized by a counterparty.

6.    Fair Value of Assets and Liabilities
Fair Value Measurement
General accounting principles for Fair Value Measurements and Disclosures define fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. These principles also establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and describes three levels of inputs that may be used to measure fair value:
Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities. The Company’s Level 1 assets include assets and liabilities that are traded in active exchange markets.
Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or market standard valuation techniques and assumptions that use significant inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the related assets or liabilities. Prices are determined using valuation methodologies such as discounted cash flow models and other similar techniques that require management’s judgment or estimation in developing inputs that are consistent with those other market participants would use when pricing similar assets and liabilities. Additionally, the Company’s embedded derivatives, all of which are associated with reinsurance treaties and longevity and mortality swaps, are classified in Level 3 since their values include significant unobservable inputs.
When inputs used to measure the fair value of an asset or liability fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety, except for fair value measurements using net asset value. For example, a Level 3 fair value measurement may include inputs that are observable (Levels 1 and 2) and unobservable (Level 3). Therefore, gains and losses for such assets and liabilities categorized within Level 3 may include changes in fair value that are attributable to both observable inputs (Levels 1 and 2) and unobservable inputs (Level 3).

The Company may utilize information from third parties, such as pricing services and brokers, to assist in determining the fair value for certain assets and liabilities; however, management is ultimately responsible for all fair values presented in the Company’s condensed consolidated financial statements. This includes responsibility for monitoring the fair value process, ensuring objective and reliable valuation practices and pricing of assets and liabilities, and approving changes to valuation methodologies and pricing sources. The selection of the valuation technique(s) to apply considers the definition of an exit price and the nature of the asset or liability being valued and significant expertise and judgment is required.

Table of Contents


The Company performs initial and ongoing analysis and review of the various techniques utilized in determining fair value to ensure that they are appropriate and consistently applied, and that the various assumptions are reasonable. The Company analyzes and reviews the information and prices received from third parties to ensure that the prices represent a reasonable estimate of the fair value and to monitor controls around pricing, which includes quantitative and qualitative analysis and is overseen by the Company’s investment and accounting personnel. Examples of procedures performed include, but are not limited to, review of pricing trends, comparison of a sample of executed prices of securities sold to the fair value estimates, comparison of fair value estimates to management’s knowledge of the current market, and ongoing confirmation that third party pricing services use, wherever possible, market-based parameters for valuation. In addition, the Company utilizes both internal and external cash flow models to analyze the reasonableness of fair values utilizing credit spread and other market assumptions, where appropriate. As a result of the analysis, if the Company determines there is a more appropriate fair value based upon the available market data, the price received from the third party is adjusted accordingly. The Company also determines if the inputs used in estimated fair values received from pricing services are observable by assessing whether these inputs can be corroborated by observable market data.
For assets and liabilities reported at fair value, the Company utilizes, when available, fair values based on quoted prices in active markets that are regularly and readily obtainable. Generally, these are very liquid investments and the valuation does not require management judgment. When quoted prices in active markets are not available, fair value is based on market valuation techniques, market comparable pricing and the income approach. The use of different techniques, assumptions and inputs may have a material effect on the estimated fair values of the Company’s securities holdings. For the periods presented, the application of market standard valuation techniques applied to similar assets and liabilities has been consistent.
The methods and assumptions the Company uses to estimate the fair value of assets and liabilities measured at fair value on a recurring basis are summarized below.
Fixed Maturity Securities – The fair values of the Company’s publicly-traded fixed maturity securities are generally based on prices obtained from independent pricing services. Prices from pricing services are sourced from multiple vendors, and a vendor hierarchy is maintained by asset type based on historical pricing experience and vendor expertise. The Company generally receives prices from multiple pricing services for each security, but ultimately uses the price from the vendor that is highest in the hierarchy for the respective asset type. To validate reasonableness, prices are periodically reviewed as explained above. Consistent with the fair value hierarchy described above, securities with quotes from pricing services are generally reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. If the pricing information received from third party pricing services is not reflective of market activity or other inputs observable in the market, the Company may challenge the price through a formal process with the pricing service.
If the Company ultimately concludes that pricing information received from the independent pricing service is not reflective of fair value, non-binding broker quotes are used, if available. If the Company concludes that the values from both pricing services and brokers are not reflective of fair value, an internally developed valuation may be prepared; however, this occurs infrequently. Internally developed valuations or non-binding broker quotes are also used to determine fair value in circumstances where vendor pricing is not available. These valuations may use significant unobservable inputs, which reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset. Observable market data may not be available in certain circumstances, such as market illiquidity and credit events related to the security. Pricing service overrides, internally developed valuations and non-binding broker quotes are generally based on significant unobservable inputs and are reflected as Level 3 in the valuation hierarchy.
The inputs used in the valuation of corporate and government securities include, but are not limited to standard market observable inputs which are derived from, or corroborated by, market observable data including market yield curve, duration, call provisions, observable prices and spreads for similar publicly traded or privately traded issues that incorporate the credit quality and industry sector of the issuer. For structured securities, valuation is based primarily on matrix pricing or other similar techniques using standard market inputs including spreads for actively traded securities, spreads off benchmark yields, expected prepayment speeds and volumes, current and forecasted loss severity, rating, weighted average coupon, weighted average maturity, average delinquency rates, geographic region, debt-service coverage ratios and issuance-specific information including, but not limited to: collateral type, payment terms of the underlying assets, payment priority within the tranche, structure of the security, deal performance and vintage of loans.
When observable inputs are not available, the market standard valuation techniques for determining the estimated fair value of certain types of securities that trade infrequently, and therefore have little or no price transparency, rely on inputs that are significant to the estimated fair value that are not observable in the market or cannot be derived principally from or corroborated by observable market data. These unobservable inputs can be based in large part on management judgment or estimation, and cannot be supported by reference to market activity. Even though unobservable, these inputs are based on assumptions deemed appropriate given the circumstances and are believed to be consistent with what other market participants would use when pricing such securities.

The fair values of private placement securities are primarily determined using a discounted cash flow model. In certain cases these models primarily use observable inputs with a discount rate based upon the average of spread surveys collected from private market intermediaries who are active in both primary and secondary transactions, taking into account, among other factors, the credit quality and industry sector of the issuer and the reduced liquidity associated with private placements. Generally, these securities have been reflected within Level 3. For certain private fixed maturities, the discounted cash flow model may also incorporate significant unobservable inputs, which reflect the Company’s own assumptions about the inputs market participants would use in pricing the security. To the extent management determines that such unobservable inputs are not significant to the price of a security, a Level 2 classification is made. Otherwise, a Level 3 classification is used.

Embedded Derivatives – The fair value of embedded derivative liabilities, including those calculated by third parties, are monitored through the use of attribution reports to quantify the effect of underlying sources of fair value change, including capital market inputs based on policyholder account values, interest rates and short-term and long-term implied volatilities, from period to period. Actuarial assumptions are based on experience studies performed internally in combination with available industry information and are reviewed on a periodic basis, at least annually.
For embedded derivative liabilities associated with the underlying products in reinsurance treaties, primarily equity-indexed and variable annuity treaties, the Company utilizes a discounted cash flow model, which includes an estimate of future equity option purchases and an adjustment for a CVA. The variable annuity embedded derivative calculations are performed by third parties based on methodology and input assumptions provided by the Company. To validate the reasonableness of the resulting fair value, the Company’s internal actuaries perform reviews and analytical procedures on the results. The capital market inputs to the model, such as equity indexes, short-term equity volatility and interest rates, are generally observable. The valuation also requires certain significant inputs, which are generally not observable and accordingly, the valuation is considered Level 3 in the fair value hierarchy, see “Level 3 Measurements and Transfers” below for a description.
The fair value of embedded derivatives associated with funds withheld reinsurance treaties is determined based upon a total return swap technique with reference to the fair value of the investments held by the ceding company that support the Company’s funds withheld at interest asset with an adjustment for a CVA. The fair value of the underlying assets is generally based on market observable inputs using industry standard valuation techniques. The valuation also requires certain significant inputs, which are generally not observable and accordingly, the valuation is considered Level 3 in the fair value hierarchy, see “Level 3 Measurements and Transfers” below for a description.
Credit Valuation Adjustment – The Company uses a structural default risk model to estimate a CVA. The input assumptions are a combination of externally derived and published values (default threshold and uncertainty), market inputs (interest rate, equity price per share, debt per share, equity price volatility) and insurance industry data (Loss Given Default), adjusted for market recoverability.
Cash Equivalents and Short-Term Investments – Cash equivalents and short-term investments include money market instruments, commercial paper and other highly liquid debt instruments. Money market instruments are generally valued using unadjusted quoted prices in active markets that are accessible for identical assets and are primarily classified as Level 1. The fair value of certain other cash equivalents and short-term investments, such as floating rate notes and bonds with original maturities less than twelve months, are based upon other market observable data and are typically classified as Level 2. However, certain short-term investments may incorporate significant unobservable inputs resulting in a Level 3 classification. Various time deposits carried as cash equivalents or short-term investments are not measured at estimated fair value and therefore are excluded from the tables presented.
Equity Securities – Equity securities consist principally of exchange-traded funds and preferred stock of publicly and privately traded companies. The fair values of publicly traded equity securities are primarily based on quoted market prices in active markets and are classified within Level 1 in the fair value hierarchy. The fair values of preferred equity securities, for which quoted market prices are not readily available, are based on prices obtained from independent pricing services and these securities are generally classified within Level 2 in the fair value hierarchy. Non-binding broker quotes for equity securities are generally based on significant unobservable inputs and are reflected as Level 3 in the fair value hierarchy.
FVO Contractholder-Directed Unit-Linked Investments – FVO contractholder-directed investments supporting unit-linked variable annuity type liabilities primarily consist of exchange-traded funds and, to a lesser extent, fixed maturity securities and cash and cash equivalents. The fair values of the exchange-traded securities are primarily based on quoted market prices in active markets and are classified within Level 1 of the hierarchy. The fair value of the fixed maturity contractholder-directed securities is determined on a basis consistent with the methodologies described above for fixed maturity securities and are classified within Level 2 of the hierarchy.

Table of Contents


Derivative Assets and Derivative Liabilities – All of the derivative instruments utilized by the Company, except for longevity and mortality swaps, are classified within Level 2 on the fair value hierarchy. These derivatives are principally valued using an income approach. Valuations of interest rate contracts are based on present value techniques, which utilize significant inputs that may include the swap yield curve, LIBORLondon Interbank Offered Rate (“LIBOR”) basis curves, and repurchase rates. Valuations of foreign currency contracts, are based on present value techniques, which utilize significant inputs that may include the swap yield curve, LIBOR basis curves, currency spot rates, and cross currency basis curves. Valuations of credit contracts are based on present value techniques, which utilize significant inputs that may include the swap yield curve, credit curves, and recovery rates. Valuations of equity market contracts, are based on present value techniques, which utilize significant inputs that may include the swap yield curve, spot equity index levels, and dividend yield curves. Valuations of equity market contracts, option-based, are based on option pricing models, which utilize significant inputs that may include the swap yield curve, spot equity index levels, dividend yield curves, and equity volatility. The Company does not currently have derivatives, except for longevity and mortality swaps, included in Level 3 measurement.

Longevity and Mortality Swaps – The Company utilizes a discounted cash flow model to estimate the fair value of longevity and mortality swaps. The fair value of these swaps includes an accrual for premiums payable and receivable. Some inputs to the valuation model are generally observable, such as interest rates and actual population mortality experience. The valuation also requires significant inputs that are generally not observable and, accordingly, the valuation is considered Level 3 in the fair value hierarchy.
Level 3 Measurements and Transfers
As of September 30, 20162017 and December 31, 20152016, the Company classified approximately 7.0%5.9% and 8.2%6.9%, respectively, of its fixed maturity securities in the Level 3 category. These securities primarily consist of private placement corporate securities and bank loans as well as Canadian provincial strips with inactive trading markets. Additionally, the Company has included asset-backed securities with subprime exposure and mortgage-backed securities with below investment grade ratings in the Level 3 category due to market uncertainty associated with these securities and the Company’s utilization of unobservable information from third parties for the valuation of these securities.

The significant unobservable inputs used in the fair value measurement of the Company’s corporate, sovereign, government-backed, and other political subdivision investments are probability of default, liquidity premium and subordination premium. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumptions used for the liquidity premium and subordination premium. For securities with a fair value derived using the market comparable pricing valuation technique, liquidity premium is the only significant unobservable input.
The significant unobservable inputs used in the fair value measurement of the Company’s asset and mortgage-backed securities are prepayment rates, probability of default, liquidity premium and loss severity in the event of default. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the liquidity premium and loss severity and a directionally opposite change in the assumption used for prepayment rates.
The actuarial assumptions used in the fair value of embedded derivatives which include assumptions related to lapses, withdrawals, and mortality, are based on experience studies performed by the Company in combination with available industry information and are reviewed on a periodic basis, at least annually. The significant unobservable inputs used in the fair value measurement of embedded derivatives are assumptions associated with policyholder experience and selected capital market assumptions for equity-indexed and variable annuities. The selected capital market assumptions, which include long-term implied volatilities, are projections based on short-term historical information. Changes in interest rates, equity indices, equity volatility, CVA, and actuarial assumptions regarding policyholder experience may result in significant fluctuations in the value of embedded derivatives.
Fair value measurements associated with funds withheld reinsurance treaties are generally not materially sensitive to changes in unobservable inputs associated with policyholder experience. The primary drivers of change in these fair values are related to movements of credit spreads, which are generally observable. Increases (decreases) in market credit spreads tend to decrease (increase) the fair value of embedded derivatives. Increases (decreases) in the CVA assumption tend to decrease (increase) the magnitude of the fair value of embedded derivatives.
Fair value measurements associated with variable annuity treaties are sensitive to both capital markets inputs and policyholder experience inputs. Increases (decreases) in lapse rates tend to decrease (increase) the value of the embedded derivatives associated with variable annuity treaties. Increases (decreases) in the long-term volatility assumption tend to increase (decrease) the fair value of embedded derivatives. Increases (decreases) in the CVA assumption tend to decrease (increase) the magnitude of the fair value of embedded derivatives.

The actuarial assumptions used in the fair value of longevity and mortality swaps include assumptions related to the level and volatility of mortality. The assumptions are based on studies performed by the Company in combination with available industry information and are reviewed on a periodic basis, at least annually.

The Company recognizes transfers of assets and liabilities into and out of levels within the fair value hierarchy at the beginning of the quarter in which the actual event or change in circumstances that caused the transfer occurs. Assets and liabilities transferred into Level 3 are due to a lack of observable market transactions and price information. Assets and liabilities are transferred out of Level 3 when circumstances change such that significant inputs can be corroborated with market observable data. This may be due to a significant increase in market activity for the asset or liability, a specific event, one or more significant input(s) becoming observable. Transfers out of Level 3 were primarily the result of the Company obtaining observable pricing information or a third party pricing quotation that appropriately reflects the fair value of those assets and liabilities. In addition, certain transfers out of Level 3 were also due to ratings upgrades on mortgage-backed securities that had previously had below investment-grade ratings.

Transfers from Level 1 to Level 2 are due to the lack of observable market data when pricing these securities, while transfers from Level 2 to Level 1 are due to an increase in the availability of market observable data in an active market. There were no transfers between Level 1 and Level 2 during the three and nine months ended September 30, 2016. The following tables present the transfers between Level 1 and Level 2 during the three and nine months ended September 30, 20152017 (dollars in thousands):

Mortgage Loans on Real Estate – The fair value of mortgage loans on real estate is estimated by discounting cash flows, both principal and interest, using current interest rates for mortgage loans with similar credit ratings and similar remaining maturities. As such, inputs include current treasury yields and spreads, which are based on the credit rating and average life of the loan, corresponding to the market spreads. The valuation of mortgage loans on real estate is considered Level 3 in the fair value hierarchy.
Policy Loans – Policy loans typically carry an interest rate that is adjusted annually based on an observable market index and therefore carrying value approximates fair value. The valuation of policy loans is considered Level 2 in the fair value hierarchy.

Funds Withheld at Interest – The carrying value of funds withheld at interest approximates fair value except where the funds withheld are specifically identified in the agreement. When funds withheld are specifically identified in the agreement, the fair value is based on the fair value of the underlying assets which are held by the ceding company. Ceding companies use a variety of sources and pricing methodologies, which are not transparent to the Company and may include significant unobservable inputs, to value the securities that are held in distinct portfolios, therefore the valuation of these funds withheld assets are considered Level 3 in the fair value hierarchy.
Cash and Cash Equivalents and Short-term Investments – The carrying values of cash and cash equivalents and short-term investments approximates fair values due to the short-term maturities of these instruments and are considered Level 1 in the fair value hierarchy.
Other Invested Assets – This primarily includes limited partnership interests accounted for using the cost method, structured loans, FHLB common stock, cash collateral and equity release mortgages. The fair value of limited partnership interests and other investments accounted for using the cost method is determined using the net asset value ("NAV"(“NAV”) of the Company’s ownership interest as provided in the financial statements of the investees. The fair value of structured loans is estimated based on a discounted cash flow analysis using discount rates applicable to each structured loan, this is considered Level 3 in the fair value hierarchy. The fair value of the Company’s common stock investment in the FHLB is considered to be the carrying value and it is considered Level 2 in the fair value hierarchy. The fair value of the Company'sCompany’s cash collateral is considered to be the carrying value and considered to be Level 1 in the fair value hierarchy. The fair value of the Company’s equity release mortgage loan portfolio, considered Level 3 in the fair value hierarchy, is estimated by discounting cash flows, both principal and interest, using a risk free rate plus an illiquidity premium. The cash flow analysis considers future expenses, changes in property prices, and actuarial analysis of borrower behavior, mortality and morbidity.
Accrued Investment Income – The carrying value for accrued investment income approximates fair value as there are no adjustments made to the carrying value. This is considered Level 2 in the fair value hierarchy.
Interest-Sensitive Contract Liabilities – The carrying and fair values of interest-sensitive contract liabilities reflected in the table above exclude contracts with significant mortality risk. The fair value of the Company’s interest-sensitive contract liabilities utilizes a market standard technique with both capital market inputs and policyholder behavior assumptions, as well as cash values adjusted for recapture fees. The capital market inputs to the model, such as interest rates, are generally observable. Policyholder behavior assumptions are generally not observable and may require use of significant management judgment. The valuation of interest-sensitive contract liabilities is considered Level 3 in the fair value hierarchy.
Short- and Long-term Debt/Collateral Finance and Securitization Notes – The fair value of the Company’s short- and long-term, debt and collateral finance and securitization notes is generally estimated by discounting future cash flows using market rates currently available for debt with similar remaining maturities and reflecting the credit risk of the Company, including inputs when available, from actively traded debt of the Company or other companies with similar credit quality. The valuation of short- and long-term debt, and collateral finance and securitization notes are generally obtained from brokers and is considered Level 3 in the fair value hierarchy. The Company's short-term debt represents the portion of long-term debt maturing within one year.

7.Segment Information
The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies in Note 2 of the consolidated financial statements accompanying the 20152016 Annual Report. The Company measures segment performance primarily based on profit or loss from operations before income taxes. There are no intersegment reinsurance transactions and the Company does not have any material long-lived assets. Investment income is allocated to the segments based upon average assets and related capital levels deemed appropriate to support the segment business volumes.
The Company allocates capital to its segments based on an internally developed economic capital model, the purpose of which is to measure the risk in the business and to provide a basis upon which capital is deployed. The economic capital model considers the unique and specific nature of the risks inherent in the Company’s businesses. As a result of the economic capital allocation process, a portion of investment income is attributed to the segments based on the level of allocated capital. In addition, the segments are charged for excess capital utilized above the allocated economic capital basis. This charge is included in policy acquisition costs and other insurance expenses.
The Company’s reportable segmentsCompany has geographic-based and business-based operational segments. Geographic-based operations are strategic business units that are primarily segregated by geographic region.further segmented into traditional and financial solutions businesses. Information related to revenues, income (loss) before income taxes and total assets of the Company for each reportable segment are summarized below (dollars in thousands).

The Company'sCompany’s commitments to fund investments as of September 30, 20162017 and December 31, 20152016 are presented in the following table (dollars in thousands):
 September 30, 2016 December 31, 2015

 130,324
The Company anticipates that the majority of its current commitments will be invested over the next five years; however, these commitments could become due any time at the request of the counterparties. Investments in limited partnershipspartnership interests and real estate joint ventures and private placements are carried at cost or reported using the equity method and included in other invested assets in the condensed consolidated balance sheets. Bank loans and private placements are carried at fair value and included in fixed maturity securities available-for-sale. Equity release mortgages are carried at unpaid principal balances, net of any amortized premium or discount and valuation allowance and included in other invested assets.
Contingencies
Litigation
The Company is subject to litigation in the normal course of its business. The Company currently has no material litigation. A legal reserve is established when the Company is notified of an arbitration demand or litigation or is notified that an arbitration demand or litigation is imminent, it is probable that the Company will incur a loss as a result and the amount of the probable loss is reasonably capable of being estimated.
Other Contingencies
The Company indemnifies its directors and officers as provided in its charters and by-laws. Since this indemnity generally is not subject to limitation with respect to duration or amount, the Company does not believe that it is possible to determine the maximum potential amount due under this indemnity in the future.
Guarantees
Statutory Reserve Support
RGA, through wholly-owned subsidiaries, has committed to provide statutory reserve support to third parties, in exchange for a fee, by funding loans if certain defined events occur. Such statutory reserves are required under the U.S. Valuation of Life Policies Model Regulation (commonly referred to as Regulation XXX for term life insurance policies and Regulation A-XXX for universal life secondary guarantees). The third parties have recourse to RGA should the subsidiary fail to provide the required funding,

however, as of September 30, 2016,2017, the Company does not believe that it will be required to provide any funding under these commitments as the occurrence of the defined events is considered remote. The following table presents the maximum potential obligation for these commitments as of September 30, 20162017 (dollars in millions):

Other Guarantees
RGA has issued guarantees to third parties on behalf of its subsidiaries for the payment of amounts due under certain securities borrowing and repurchase arrangements, financing arrangements and office lease obligations, whereby, if a subsidiary fails to meet an obligation, RGA or one of its other subsidiaries will make a payment to fulfill the obligation. Additionally, in limited circumstances, treaty guarantees are granted to ceding companies in order to provide them additional security, particularly in cases where RGA’s subsidiary is relatively new, unrated, or not of a significant size, relative to the ceding company. Liabilities supported by the treaty guarantees, before consideration for any legally offsetting amounts due from the guaranteed party are reflected on the Company’s condensed consolidated balance sheets in future policy benefits. Potential guaranteed amounts of future payments will vary depending on production levels and underwriting results. Guarantees related to borrowed securities borrowing and repurchase arrangements provide additional security to third parties should a subsidiary fail to return the borrowedprovide securities when due. RGA’s guarantees issued as of September 30, 20162017 and December 31, 20152016 are reflected in the following table (dollars in thousands):

The effective tax rate for the third quarter of 2017 was lower than the U.S. Statutory rate of 35.0% primarily as a result of income generated in non-U.S. jurisdictions with lower tax rates than the U.S. The first nine months of 2017 also includes a reduction related to differences in tax bases in foreign jurisdictions and a tax benefit from the filing of amended returns, which was partially offset with a valuation allowance established related to amended return filings. The third quarter of 2016 effective tax rate was lower than the U.S. Statutory rate of 35.0% primarily as a result of effectively settling an uncertain tax positionsposition during the quarter and adjustments related to the filing of the U.S.US Federal Income tax return. The first nine months of 2016 effective tax rate was lower than the U.S. Statutory rate of 35.0% primarily as a result of tax benefits

from income in non-U.S. jurisdictions with lower tax rates than the U.S. The third quarter and first nine months effective tax rates were further reduced by differences in tax bases in foreign jurisdictions.
The third quarter and first nine months of 2015 effective tax rates were higher than the U.S. Statutory rate of 35.0% primarily as a result of a tax accrual related to the Active Financing Exception business extender provision that the U.S. Congress did not pass prior to the end of the quarter and a loss in Australia which has a lower tax rate than the U.S. The higher rate was partially offset by tax benefits associated with claims experience on certain treaties and income in other jurisdictions with rates lower than the U.S.

The Company has made $8.0$5.0 million in pension contributions during the first nine months of 20162017 and expects to make total pension contributions between $8.0$5.0 million and $10.0 million in 2016.2017.
11.Equity Based Compensation
Equity compensation expense was $8.3 million and $5.7 million in the third quarter of 2016 and 2015, respectively. In the first quarter of 2016, the Company granted 0.3 million stock appreciation rights at $93.53 weighted average exercise price per share and 0.2 million performance contingent units to employees. Additionally, non-employee directors were granted a total of 8,908 shares of common stock. As of September 30, 2016, 1.6 million share options at a weighted average strike price per share of $56.55 were vested and exercisable, with a remaining weighted average exercise period of 4.7 years. As of September 30, 2016, the total compensation cost of non-vested awards not yet recognized in the condensed consolidated financial statements was $33.4 million. It is estimated that these costs will vest over a weighted average period of 1.9 years.
12.Reinsurance
The Company generally reports retrocession activity on a gross basis. Amounts paid or deemed to have been paid for reinsurance are reflected in reinsurance ceded receivables. The cost of reinsurance related to long-duration contracts is recognized over the terms of the reinsured policies on a basis consistent with the reporting of those policies.
Retrocession reinsurance treaties do not relieve the Company from its obligations to direct writing companies. Failure of retrocessionaires to honor their obligations could result in losses to the Company. Consequently, allowances would be established for amounts deemed uncollectible. At September 30, 20162017 and December 31, 2015,2016, no allowances were deemed necessary. The Company regularly evaluates the financial condition of the insurance companies from which it assumes and to which it cedes reinsurance.
Retrocessions are arranged through the Company’s retrocession pools for amounts in excess of the Company’s retention limit. As of September 30, 20162017 and December 31, 2015,2016, all rated retrocession pool participants followed by the A.M. Best Company were rated “A- (excellent)” or better. The Company verifies retrocession pool participants’ ratings on a quarterly basis. For a majority of the retrocessionaires that were not rated, security in the form of letters of credit or trust assets has been posted. In addition, the

13.Financing Activities

In June 2016, RGA issued 3.95% Senior Notes due September 15, 2026 with a face amount of $400.0 million and 5.75% Fixed-To-Floating Rate Subordinated Debentures due June 15, 2056 with a face amount of $400.0 million. These securities have been registered with the Securities and Exchange Commission. The net proceeds from these offerings were approximately $791.0 million and will be used in part to repay upon maturity the Company’s $300.0 million 5.625% Senior Notes that mature in March 2017. The remainder will be used for general corporate purposes. Capitalized issue costs were approximately $9.0 million.

14.12.New Accounting Standards
Changes to the general accounting principles are established by the Financial Accounting Standards Board ("FASB"(“FASB”) in the form of accounting standards updates to the FASB Accounting Standards Codification™. Accounting standards updates not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s condensed consolidated financial statements.
Adoption of New Accounting Standards
Transfers and ServicingStock Compensation

In June 2014,March 2016, the FASB amendedupdated the general accounting principlesprincipal for TransfersStock Compensation which changed how companies account for certain aspects of share-based payment awards to employees. The updated guidance requires excess tax benefits and Servicing as it relates todeficiencies from share-based payment awards be recorded in income tax expense in the income statement. Previously, excess tax benefits and deficiencies were recognized in shareholders’ equity or deferred taxes on the balance sheet depending on the tax situation of the Company. In addition, the updated guidance also changes the accounting for repurchase-to-maturity transactions, repurchase financings,forfeitures and disclosures. This amendmentstatutory tax withholding requirements, as well as the classification in the statement of cash flows. The new standard generally requires entities to account for repurchase-to-maturity transactionsa modified retrospective transition through a cumulative-effect adjustment as secured borrowings, eliminates guidance on linked repurchase financing transactions, and expands disclosure requirements related to certain transfers of financial assets that are accounted for as sales and certain transfers accounted for as secured borrowings. These amendments are effective for annual years, and interim periods within those years, beginning after December 15, 2014. Certain interim period disclosures for repurchase agreements and securities lending transactions were not required until the second quarter of 2015. The adoption of this amendment did not have an impact on the Company's condensed consolidated financial statements other than the addition of the required disclosures.beginning of the period of adoption, with certain provisions requiring either a prospective or retrospective transition. The Company adopted these amendmentsthe new guidance on January 1, 2017. Upon adoption, the Company recognized excess tax benefits of approximately $17.7 million in deferred tax assets that were previously not recognized in a cumulative-effect adjustment increasing retained earnings by $17.7 million. The Company also recorded excess tax benefits of approximately $2.8 million and the required disclosures are provided in Note 4 "Investments."
Business Combinations
In September 2015, the FASB amended the general accounting principles for Business Combinations as it relates to measurement period adjustments. This amendment requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period$7.2 million in the reporting period in whichprovision for income taxes for the adjustment amounts are determined, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. The adjustments related to previous reporting periods since the acquisition date must be disclosed by income statement line item either on the face of the income statement or in the notes. The Company adopted this amendment during the three and nine months ended September 30, 2015. Accordingly,2017, respectively. The number of weighted average diluted shares outstanding were also adjusted to exclude excess tax benefits from the Company applied the amendments in this update to the measurement period adjustments made during the three months ended September 30, 2015 with no material effect on previous-period or current-period earnings.

Debt Issuance Costs
In April 2015, the FASB issued accounting guidance, “Simplifying the Presentation of Debt Issuance Costs” which requires capitalized debt issuance costs related to a recognized debt liability be presentedassumed proceeds in the statementdiluted shares calculation resulting in an immaterial increase in the number of financial position as a direct deduction from the carrying amount of that debt. This standard is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted for financial statements not yet issued.dilutive shares outstanding. The Company also elected to adopt this standard ascontinue estimating forfeitures for purposes of December 31, 2015, with retrospective application to all balance sheets presented.
Fair Value Measurement
In May 2015,recognizing share-based compensation. Other aspects of the FASB issued amended guidance onadoption of the disclosures for investments in certain entities that calculate net asset value ("NAV") per share (or its equivalent). The amendments remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the NAV per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The guidance is effective for fiscal years beginning after December 15, 2015 and for interim periods within those years. Early application is permitted. The Company adopted the guidance for the year ended December 31, 2015 and applied the guidance retrospectively. Adoption of theupdated guidance did not have a material impact onto the Company’s condensed consolidated financial statements.
Future Adoption of New Accounting Standards
Financial Services - Insurance
In May 2015, the FASB amended the general accounting principle for Financial Services - Insurance which expanded the breadth of disclosures that an insurance entity must provide about its short-duration insurance contracts. This amendment requires insurance entities to disclose for annual reporting periods information about the liability for unpaid claims and claim adjustment expenses. The amendment also requires insurance entities to disclose information about significant changes in methodologies and assumptions used to calculate the liability for unpaid claims and claim adjustment expenses, including reasons for the change and the effects on the financial statements. In addition, the amendment requires insurance entities to disclose for annual and interim reporting periods a roll-forward of the liability for unpaid claims and claim adjustment expenses. This amendment focuses only on disclosure; it does not change the accounting model for short-duration contracts. The update is effective for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. The new guidance should be applied retrospectively by providing comparative disclosures for each period presented, except for those requirements that apply only to the current period. The adoption of this amendment is not expected to have an impact on the Company's condensed consolidated financial statements other than the addition of the required disclosures.
Financial Instruments
In January 2016, the FASB amended the general accounting principle for Financial Instruments,, effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017.the Company January 1, 2018. The amendment revises the accounting related to (1) the classification and measurement of investments in equity securities, (2) the presentation of certain fair value changes for financial liabilities measured at fair value, (3) certain disclosure requirements associated with the fair value of financial instruments. The new guidance should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. The Company is currently evaluating the impactadoption of this amendment is not expected to have a material impact on its condensed consolidatedthe Company’s financial statements.statements; however, it could result in net income volatility depending on the composition of the Company’s investment portfolio and changes in the fair value of equity securities.
In June 2016, the FASB amended the existing impairment guidance of Financial Instruments.Instruments. The amendment adds to U.S. GAAP an impairment model, known as current expected credit loss ("CECL"(“CECL”) model that is based on expected losses rather than incurred

47

Table of Contents


losses. For traditional and other receivables, held-to-maturity debt securities, loans and other instruments entities will be required to use the new forward-looking "expected loss"“expected loss” model that generally will result in earlier recognition of allowance for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses similar to what they do today, except the losses will be recognized as allowances rather than reduction to the amortized cost of the securities. This guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019,the Company January 1, 2020, with early adoption permitted. The guidance will be adopted through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Company is currently evaluating the impact of this amendment on its condensed consolidated financial statements.
Leases
In February 2016, the FASB issued guidance which will replace most existing lease accounting guidance. The new standard, based on the principle that entities should recognize assets and liabilities arising from leases, does not significantly change the lessees’ recognition, measurement and presentation of expenses and cash flows from the previous accounting standard. Leases are classified

48

Table of Contents


as finance or operating. The new standard'sstandard’s primary change is the requirement for entities to recognize a lease liability for payments and a right of use asset representing the right to use the leased asset during the term of operating lease arrangements. Lessees are permitted to make an accounting policy election to not recognize the asset and liability for leases with a term of twelve months or less. Lessors’ accounting is largely unchanged from the previous accounting standard. In addition, the new standard expands the disclosure requirements of lease arrangements. Lessees and lessors will use a modified retrospective transition approach, which includes a number of practical expedients. This guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018,the Company January 1, 2019, with early adoption permitted. The Company is currently evaluating the impact of this amendment on its condensed consolidated financial statements.
Stock Compensation
In March 2016, the FASB updated the general accounting principal for Stock Compensation. This update was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016. This guidance will be applied either prospectively, retrospectively or using a modified retrospective transition method, depending on the area covered in this update. Early adoption is permitted. The Company is currently evaluating the impact of this amendment on its condensed consolidated financial statements.
Income Taxes
In October 2016, the FASB amended the general accounting principal for Income Taxes, effective for annual and interim periods beginning after December 15, 2017.the Company January 1, 2018. The amendment requires entities to recognize the tax consequences of intercompany asset transfers, except for inventory, at the transaction date. Current U.S. GAAP prohibits entities from recognizing the income tax consequences from intercompany asset transfers. The seller defers any net tax effect, and the buyer is prohibited from recognizing a deferred tax asset on the difference between the newly created tax basis of the asset in its tax jurisdiction and its financial statement carrying amount as reported in the condensed consolidated financial statements. The amendment requires entities to recognize these tax consequences in the period in which the transfer occurred. There will be an immediate effect on earnings if the tax rates in the seller’s and buyer’s tax jurisdictions are different. This amendment will be applied using a modified retrospective transition method with a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. The adoption of this amendment will not have a material impact on the Company’s condensed consolidated financial statements.
Derivative and Hedging
In August 2017, the FASB updated the general accounting principal for Derivatives and Hedging. The updated guidance improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting in current GAAP related to the assessment of hedge effectiveness. The updated guidance is effective for the Company January 1, 2019, with early adoption permitted. The Company is currently evaluating the impact of this amendmentamending on its condensed consolidated financial statements.

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 including, among others, statements relating to projections of the strategies, earnings, revenues, income or loss, ratios, future financial performance, and growth potential of the Company. The words “intend,” “expect,” “project,” “estimate,” “predict,” “anticipate,” “should,” “believe,” and other similar expressions also are intended to identify forward-looking statements. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. Future events and actual results, performance, and achievements could differ materially from those set forth in, contemplated by, or underlying the forward-looking statements.
Numerous important factors could cause actual results and events to differ materially from those expressed or implied by forward-looking statements including, without limitation, (1) adverse capital and credit market conditions and their impact on the Company’s liquidity, access to capital and cost of capital, (2) the impairment of other financial institutions and its effect on the Company’s business, (3) requirements to post collateral or make payments due to declines in market value of assets subject to the Company’s collateral arrangements, (4) the fact that the determination of allowances and impairments taken on the Company’s investments is highly subjective, (5) adverse changes in mortality, morbidity, lapsation or claims experience, (6) changes in the Company’s financial strength and credit ratings and the effect of such changes on the Company’s future results of operations and financial condition, (7) inadequate risk analysis and underwriting, (8) general economic conditions or a prolonged economic downturn affecting the demand for insurance and reinsurance in the Company’s current and planned markets, (9) the availability and cost of collateral necessary for regulatory reserves and capital, (10) market or economic conditions that adversely affect the value of the Company’s investment securities or result in the impairment of all or a portion of the value of certain of the Company’s investment securities, that in turn could affect regulatory capital, (11) market or economic conditions that adversely affect the Company’s ability to make timely sales of investment securities, (12) risks inherent in the Company’s risk management and investment strategy, including changes in investment portfolio yields due to interest rate or credit quality changes, (13) fluctuations in U.S. or foreign currency exchange rates, interest rates, or securities and real estate markets, (14) adverse litigation or arbitration results, (15) the adequacy of reserves, resources and accurate information relating to settlements, awards and terminated and discontinued lines of business, (16) the stability of and actions by governments and economies in the markets in which the Company operates, including ongoing uncertainties regarding the amount of United StatesU.S. sovereign debt and the credit ratings thereof, (17) competitive factors and competitors’ responses to the Company’s initiatives, (18) the success of the Company’s clients, (19) successful execution of the Company’s entry into new markets, (20) successful development and introduction of new products and distribution opportunities, (21) the Company’s ability to successfully integrate acquired blocks of business and entities, (22) action by regulators who have authority over the Company’s reinsurance operations in the jurisdictions in which it operates, (23) the Company’s dependence on third parties, including those insurance companies and reinsurers to which the Company cedes some reinsurance, third-party investment managers and others, (24) the threat of natural disasters, catastrophes, terrorist attacks, epidemics or pandemics anywhere in the world where the Company or its clients do business, (25) interruption or failure of the Company'sCompany’s telecommunication, information technology or other operational systems, or the Company'sCompany’s failure to maintain adequate security to protect the confidentiality or privacy of personal or sensitive data stored on such systems, (26) changes in laws, regulations, and accounting standards applicable to the Company, its subsidiaries, or its business, (27) the effect of the Company’s status as an insurance holding company and regulatory restrictions on its ability to pay principal of and interest on its debt obligations, and (28) other risks and uncertainties described in this document and in the Company’s other filings with the SEC.

Overview
RGA is an insurance holding company that was formed on December 31, 1992. The condensed consolidated financial statements include the assets, liabilities and results of operations of RGA and its subsidiaries, all of which are wholly owned (collectively, the Company).
The Company providesis one of the leading life reinsurers in North America based on premiums and the amount of life reinsurance in force, providing traditional reinsurance and non-traditional reinsurancefinancial solutions to its clients. Traditional reinsurance includes individual and group life and health, disability, and critical illness reinsurance. Non-traditional reinsuranceFinancial solutions includes longevity reinsurance, asset-intensive reinsurance, and financial reinsurance.

Table of Contents


The Company derives revenues primarily from renewal premiums from existing reinsurance treaties, new business premiums from existing or new reinsurance treaties, fee income from non-traditional reinsurancefinancial solutions business and income earned on invested assets.
Historically, the Company’s primary business has been traditional life reinsurance, which involves reinsuring life insurance policies that are often in force for the remaining lifetime of the underlying individuals insured, with premiums earned typically over a

Table of Contents


period of 10 to 30 years. Each year, however, a portion of the business under existing treaties terminates due to, among other things, lapses or voluntary surrenders of underlying policies, deaths of insureds, and the exercise of recapture options by ceding companies. The Company has expanded its non-traditional reinsurancefinancial solutions business, including significant asset-intensive or annuity, transactions, which allow its clients to take advantage of growth opportunities and manage their capital, longevity and investment risk.
The Company’s long-term profitability largely depends on the volume and amount of death- and health-related claims incurred and the ability to adequately price the risks it assumes. While death claims are reasonably predictable over a period of many years, claims become less predictable over shorter periods and are subject to significant fluctuation from quarter to quarter and year to year. Additionally, the Company generates profits on investment spreads associated with the reinsurance of investment type contracts and generates fees from financial reinsurance transactions which are typically shorter duration than its traditional life reinsurance business. The Company believes its sources of liquidity are sufficient to cover potential claims payments on both a short-term and long-term basis.
As is customary in the reinsurance business, clients continually update, refine, and revise reinsurance information provided to the Company. Such revised information is used by the Company in preparation of its condensed consolidated financial statements and the financial effects resulting from the incorporation of revised data are reflected in the current period.
The Company’s long-term profitability primarily depends on the volume and amount of death and health-related claims incurred and the ability to adequately price the risks it assumes. While death claims are reasonably predictable over a period of many years, claims become less predictable over shorter periods and are subject to significant fluctuation from quarter to quarter and year to year. The Company believes its sources of liquidity are sufficient to cover potential claims payments on both a short-term and long-term basis.Segment Presentation
The Company has geographic-based and business-based operational segments: U.S. and Latin America; Canada; Europe, Middle East and Africa; Asia Pacific; and Corporate and Other.segments. Geographic-based operations are further segmented into traditional and non-traditionalfinancial solutions businesses. The Company’s segments primarily write reinsurance business that is wholly or partially retained in one or more of RGA’s reinsurance subsidiaries.
The Company allocates capital to its segments based on an internally developed economic capital model, the purpose of which is to measure the risk in the business and to provide a consistent basis upon which capital is deployed. The economic capital model considers the unique and specific nature of the risks inherent in RGA’s businesses.
As a result of the economic capital allocation process, a portion of investment income is credited to the segments based on the level of allocated capital. In addition, the segments are charged for excess capital utilized above the allocated economic capital basis. This charge is included in policy acquisition costs and other insurance expenses. Segment investment performance varies with the composition of investments and the relative allocation of capital to the operating segments.

Segment premium levels can be significantly influenced by currency fluctuations, large transactions, mix of business and reporting practices of ceding companies, and therefore may fluctuate from period to period. Although reasonably predictable over a period of years, segment claims experience can be volatile over shorter periods. See “Results of Operations by Segment” below for further information about the Company’s segments.

Consolidated net income before income taxes increased $115.2$52.6 million, or 137.9%18.3%, and $172.3$138.9 million, or 50.8%18.6%, for the three and nine months ended September 30, 2016,2017, respectively, as compared to the same periods in 2015. Consolidated2016. The increase in income beforefor third quarter of 2017 was primarily due to improved mortality experience in the U.S. operations, increased investment income, taxes increased $147.5 million, or 105.2%,new business growth in the Europe, Middle East and $210.4 million, or 39.1%,Africa (“EMEA”) and Asia Pacific operations and lower interest expense. The increase in income for the three andfirst nine months ended September 30, 2016, respectively, as comparedof 2017 was primarily due to improved mortality experience in the same periods in 2015.U.S., EMEA and Asia Pacific operations and increased investment income, partially offset by higher interest expense. The increases in investment income before income taxesare discussed below and the changes in interest expense for the third quarter and first nine months were primarily due toare discussed within the Corporate and Other section. Foreign currency fluctuations resulted in an increase in investment related gains, higher investment income and improved mortality experience in the U.S. operations compared to the prior year. The increase in investment related gains was largely due to changes in the fair value of embedded derivatives on modco or funds withheld treaties within the U.S. segment. The effect of the change in fair value of these embedded derivatives on income is discussed below. The increase(decrease) in income before income taxes for the third quarter also reflects a decrease in impairments on fixed maturity and equity securities of $23.1 million, compared to the same period in 2015. Results for the first nine months of 2016 also benefited from a $15.4 million reduction in interest expense due to the effective settlement of uncertain tax positions recognized in the second quarter. Foreign currency fluctuations relative to the prior year unfavorably affected income before income taxes by approximately $4.4$2.0 million and $19.3$(7.4) million for the third quarter and first nine months of 2016,2017, as compared to the same periods in 2015.2016.
The Company recognizes in consolidated income, any changes in the fair value of embedded derivatives on modco or funds withheld treaties, equity-indexed annuity treaties (“EIAs”) and variable annuity products. The combined changes in these three types of embedded derivatives, after adjustment for deferred acquisition costs and retrocession, resulted in an increasea decrease in consolidated income before income taxes of approximately $212.8 million and $88.7$8.9 million in the third quarter of 2017 and an increase of $218.2 million in the first nine months of 2016,2017, respectively, as compared to the same periods in 2015.2016. This fluctuation does not affect current cash flows, crediting rates or spread performance on the underlying treaties. Therefore, management believes it is helpful to distinguish between the effects of changes in these embedded derivatives, net of related hedging activity and deferred acquisition costs, and the primary factors that drive profitability of the underlying treaties, namely investment income, fee income, and interest credited. The individual effect on income before income taxes for these three types of embedded derivatives is as follows:

The change in the value of embedded derivatives related to reinsurance treaties written on a modco or funds withheld basis are subject to the general accounting principles for derivatives and hedging related to embedded derivatives. The unrealized gains and losses associated with these embedded derivatives, after adjustment for deferred acquisition costs, resulted in an increasea decrease in income before income taxes of $33.0 million and $30.7$3.3 million in the third quarter of 2017 and an increase of $53.3 million in the first nine months of 2016, respectively,2017, as compared to the same periods in 2015.2016.
Changes in risk-free rates used in the fair value estimates of embedded derivatives associated with EIAs affect the amount of unrealized gains and losses the Company recognizes. The unrealized gains and losses associated with EIAs, after adjustment for deferred acquisition costs and retrocession, resulted in a decrease inincreased income before income taxes of $4.2by $0.1 million and $8.8$20.0 million in the third quarter and first nine months of 2016,2017, respectively, as compared to the same periods in 2015.2016.
The change in the Company’s liability for variable annuities associated with guaranteed minimum living benefits affects the amount of unrealized gains and losses the Company recognizes. The unrealized gains and losses associated with guaranteed minimum living benefits, after adjustment for deferred acquisition costs, increasedresulted in a decrease in income before income taxes by $184.0 million and $66.8of $5.7 million in the third quarter of 2017 and an increase of $144.9 million in the first nine months of 2016, respectively,2017, as compared to the same periods in 2015.2016. After consideration of the change in fair value of freestanding derivatives used to hedge this liability, income before income taxes decreased by $2.2 million in the third quarter of 2017 and increased by $6.9 million in the first nine months of 2017, as compared to the same periods in 2016.
Consolidated net premiums increased $162.4$238.0 million, or 7.8%10.6%, and $513.5$580.2 million, or 8.2%8.6%, for the three and nine months ended September 30, 2016,2017, as compared to the same periods in 2015,2016, primarily due to growth in life reinsurance in force and large in force block transactions entered into during the latter part of 2015.force. Foreign currency fluctuations unfavorably affectedresulted in an increase (decrease) in net premiums by approximately $21.0of $18.3 million and $136.9$(17.3) million for the third quarter and first nine months of 2016,2017, as compared to the same periods in 2015.2016. Consolidated assumed life insurance in force increased to $3,297.9 billion as of September 30, 2017 from $3,082.8 billion as of September 30, 2016 from $2,849.4 billion as of September 30, 2015 due to new business production and in force transactions, partially offset by adverse foreign currency fluctuations.transactions. The Company added new business production, measured by face amount of insurance in force, of $81.3$90.7 billion and $84.6$81.3 billion during the third quarter of 20162017 and 2015,2016, respectively, and $296.4$304.8 billion and $262.1$296.4 billion during the first nine months of 2017 and 2016, and 2015, respectively. Adverse foreignForeign currency fluctuations offsetcontributed $43.6 billion to the increase in assumed life insurance in force from September 30, 2015 by $22.3 billion.2016. Management believes industry consolidation, regulatory changes and the established practice of reinsuring mortality and morbidity risks should continue to provide opportunities for growth, albeit at rates less than historically experienced in some markets.
Consolidated investment income, net of related expenses, increased $100.1$67.2 million, or 25.7%13.7%, and $147.6$175.2 million, or 11.7%12.4%, for the three and nine months ended September 30, 2016,2017, as compared to the same periods in 2015. The increase in market2016. Market value changes related to the Company’s funds withheld at interest investment associated with the reinsurance of certain EIAs increased (decreased) investment income by $59.9$(1.3) million and $24.7$73.3 million in the third quarter and first nine months of 2016,2017, respectively, as compared to the same periods in 2015.2016. The effect on investment income of the EIA's market value changes is substantially offset by a corresponding change in interest credited to policyholder account balances resulting in an insignificant effect on net income. The increase for the first nine months of 2016 also reflects strong variable investment income on alternative investments and investment prepayments and fees.

Also contributing to the increase in investment income is a larger average invested asset base, excluding spread related business, partially offset by a decrease in the average investment yield. Average invested assets at amortized cost, excluding spread related business, for the nine months ended September 30, 20162017 totaled $23.0$25.1 billion, a 10.6%9.4% increase over September 30, 2015.2016. The

average yield earned on investments, excluding spread related business, was 4.43%4.81% and 4.66%4.43% for the third quarter of 20162017 and 2015,2016, respectively, and 4.53%4.61% and 4.77%4.53% for the first nine months ended September 30, 20162017 and 2015,2016, respectively. The average yield will vary from quarter to quarter and year to year depending on a number of variables, including the prevailing interest rate and credit spread environment, prepayment fees and make-whole premiums, changes in the mix of the underlying investments and cash balances, prepayment fees recorded on the early payoff of certain investments and the timing of dividends and distributions on certain investments. The third quarter of 2017, in particular, benefited from a higher level of bond make-whole premiums and distributions from joint ventures and limited partnerships. A continued low interest rate environment is expected to put downward pressure on this yield in future reporting periods. A portion of investment income is allocated to the operating segments based upon average assets and related capital levels deemed appropriate to support the segment operations.
Total investment related gains (losses), net improvedchanged favorably (unfavorably) by $198.0$(64.0) million and $203.9$55.5 million for the three and nine months ended September 30, 2016,2017, as compared to the same periods in 2015.

During the third quarter and first nine months of 2016,2017, the favorable change(unfavorable) changes in the value of these embedded derivatives was $105.4$(26.0) million and $73.1 million respectively, as compared to the same periods in 2016. Impairments on fixed maturity securities decreased by $13.7 million in the first nine months of 2017, as compared to the same period in 2015. The third quarter also reflects a decrease in impairments on fixed maturity and equity securities of $23.1 million, compared to the same period in 2015.2016. See Note 4 - “Investments” and Note 5 - “Derivative Instruments” in the Notes to Condensed Consolidated Financial Statements for additional information on the impairment losses and derivatives.
The effective tax rate on a consolidated basis was 30.9%33.1% and 40.4%30.9% for the three months ended September 30,third quarter 2017 and 2016, and 2015, respectively, and 31.7%31.8% and 37.0%31.7% for the first nine months of 20162017 and 2015,2016, respectively. The effective tax rate for the third quarter of 20162017 was lower than the U.S. Statutory rate of 35% primarily as a result of income generated in non-U.S. jurisdictions with lower tax rates than the U.S. The first nine months of 2017 also includes a reduction related to differences in tax bases in foreign jurisdictions and a tax benefit from the filing of amended returns, which was partially offset with a valuation allowance established related to amended return filings. The effective tax rate for the third quarter of 2016 was lower than the U.S. Statutory rate of 35.0% primarily as a result of effectively settling an uncertain tax positionsposition during the quarter and adjustments related to the filing of the U.S.US Federal Income tax return. The first nine months of 2016 effective tax rate was lower than the U.S. Statutory rate of 35.0% primarily as a result of tax benefits from income in non-U.S. jurisdictions with lower tax rates than the U.S. The third quarter and first nine months effective tax rates were further reduced by differences in tax bases in foreign jurisdictions. The third quarter and first nine months of 2015 effective tax rates were higher than the U.S. Statutory rate of 35.0% primarily as a result of a tax accrual related to the Active Financing Exception business extender provision that the U.S. Congress did not pass prior to the end of the quarter and a loss in Australia which has a lower tax rate than the U.S. The high rate was partially offset with tax benefits associated with claims experience on certain treaties and income in other jurisdictions with rates lower than the U.S.

Critical Accounting Policies
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”)GAAP requires the application of accounting policies that often involve a significant degree of judgment. Management, on an ongoing basis, reviews estimates and assumptions used in the preparation of financial statements. If management determines that modifications in assumptions and estimates are appropriate given current facts and circumstances, results of operations and financial position as reported in the condensed consolidated financial statements could change significantly.
Management believes the critical accounting policies relating to the following areas are most dependent on the application of estimates and assumptions:
Premiums receivable;
Deferred acquisition costs;
Liabilities for future policy benefits and incurred but not reported claims;
Valuation of investments and other-than-temporary impairments to specific investments;
Valuation of embedded derivatives; and
Income taxes.
A discussion of each of the critical accounting policies may be found in the Company’s 20152016 Annual Report under “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies.”
Further discussion and analysis of the results for 2016 compared to 2015 are presented by segment.

Results of Operations by Segment

U.S. and Latin America Operations
The U.S. and Latin America operations include business generated by its offices in the U.S., Mexico and Brazil. The offices in Mexico and Brazil provide services to clients in other Latin American countries. U.S. and Latin America operations consist of two major segments: Traditional and Non-Traditional.Financial Solutions. The Traditional segment primarily specializes in individual mortality-risk reinsurance and to a lesser extent, group, health and long-term care reinsurance. The Non-TraditionalFinancial Solutions segment consists of Asset-Intensive and Financial Reinsurance. Asset-Intensive within the Non-TraditionalFinancial Solutions segment provides coinsurance of annuities and corporate-owned life insurance policies and to a lesser extent also issues fee-based synthetic guaranteed investment contracts, which include investment-only, stable value contracts. Financial Reinsurance within the Non-TraditionalFinancial Solutions segment primarily involves assisting ceding companies in meeting applicable regulatory requirements by enhancing the ceding companies’ financial strength and regulatory surplus position through relatively low risk reinsurance transactions. Typically these transactions do not qualify as reinsurance under GAAP, due to the low-risk nature of the transactions, so only the related net fees are reflected in other revenues on the condensed consolidated statements of income.

Income before income taxes increased by $87.9$69.8 million, or 95.6%38.8%, and $118.8$144.5 million, or 37.4%33.1%, for the three and nine months ended September 30, 2016,2017, as compared to the same periods in 2015. For both2016. The increase in income before income taxes for the third quarter andwas primarily due to strong mortality experience in the Traditional segment as well as higher variable investment income. The increase was offset somewhat by a decrease in investment related gains in the Financial Solutions segment. The increase in income before income taxes for the first nine months as compared to same periods in 2015,is the favorable increases were driven byresult of several factors, including changes in the value of the embedded derivatives associated with reinsurance treaties structured on a modco or funds withheld, basis, improved claims experiencean increase in the Traditional segment, and a higher asset base, driven largely by acquisitions of in force blocks late in 2015. Additionally, quarter over quarter the Asset Intensive segment benefited from higher investment related gains.capital gains and additional variable investment income.
Traditional Reinsurance
The U.S. and Latin America Traditional segment provides life and health reinsurance to clients for a variety of products through yearly renewable term, coinsurance and modified coinsurancemodco agreements. These reinsurance arrangements may involve either facultative or automatic agreements.
Income before income taxes for the U.S. and Latin America Traditional segment increased by $21.4$83.4 million, or 38.5%108.2%, and $83.3$41.5 million, or 53.3%, for the three and nine months ended September 30, 2016, as compared to the same periods in 2015. The increases were primarily due to improved claims experience and an increase in the overall asset base primarily associated with large in force block transactions executed in the fourth quarter of 2015.
Net premiums increased $126.6 million, or 11.0%, and $383.3 million, or 11.2%17.3%, for the three and nine months ended September 30, 2016,2017, as compared to the same periods in 2015.2016. The increase in the third quarter is primarily due to favorable mortality experience as compared to same period in 2016 and higher variable investment income. The favorable mortality experience was driven by both a lower number and average size of large claims. The increase in income for the first nine months was primarily due to higher variable investment.
Net premiums increased $49.7 million, or 3.9%, and $147.6 million, or 3.9%, for the three and nine months ended September 30, 2017, as compared to the same periods in 2016. The increases were primarily due to large in force block transactions executed during the latter part of 2015, significant individual health and group life transactions executed in the first six months of 2016, and expected organic premium growth. The segment added new individual life business production, measured by face amount of insurance in force of $19.7$24.8 billion and $26.4$19.7 billion for the third quarter and $93.0$75.1 billion and $61.8$93.0 billion for the first nine months of 2017 and 2016, and 2015, respectively.

Table of investment income is allocated to the various operating segments based on average assets and related capital levels deemed appropriate to support segment operations. Investment performance varies with the composition of investments and the relative allocation of capital to the operating segments.Contents


Claims and other policy benefits as a percentage of net premiums (“loss ratios”) were 88.6%84.3% and 91.2%88.6% for the third quarter and 89.0%89.2% and 91.1%89.0%, for the nine months ended September 30, 20162017 and 2015,2016, respectively. The decreasesdecrease in the loss ratios wereratio for the third quarter of 2017, as compared to the same period in 2016 was primarily due to higher than normal adverse volatility infavorable mortality experience, specifically the total countlower number and average size of individuallarge claims. For the first nine months of 2017, as compared to the same period in 2016, mortality claims duringexperience was relatively consistent.
Interest credited expense decreased $1.1 million, or 1.7%, for the three and nine months ended September 30, 2015. Although reasonably predictable over a period of years, claims can be volatile over short-term periods.
Interest credited expense decreased $0.4 million, or 1.8%, and increased $7.1 million, or 12.6%, for the three and nine months ended September 30, 2016,2017, as compared to the same periodsperiod in 2015.2016. Interest credited in this segment relates to amounts credited on cash value products which also have a significant mortality component. The increase in the first nine months relates primarily to the interest sensitive whole life products acquired in the acquisition of Aurora National Life Assurance Company ("Aurora") in the second quarter of 2015. Income before income taxes is affected by the spread between the investment income and the interest credited on the underlying products.
Policy acquisition costs and other insurance expenses as a percentage of net premiums were 14.5%14.3% and 13.8%14.5% for the third quarter and 14.2%14.0% and 14.1%14.2% for the nine months ended September 30, 20162017 and 2015,2016, respectively. Overall, whileWhile these ratios are expected to remain in a predictable range, they may fluctuate from period to period due to varying allowance levels within coinsurance-type arrangements. In addition, the amortization pattern of previously capitalized amounts, which are subject to the form of the reinsurance agreement and the underlying insurance policies, may vary. Also, the mix of first year coinsurance business versus yearly renewable term business can cause the percentage to fluctuate from period to period.period
Other operating expenses increased $3.4 million, or 12.2%, and $11.3 million, or 13.9%, for the three and nine months ended September 30, 2016, as compared to the same periods in 2015. Contributing to the increase was an expansion in underwriting personnel to support clients. Other operating expenses, as a percentage of net premiums remained constant at 2.4% and 2.4% for the third quarter and 2.4% and 2.4% first nine months of 2017 and 2016, respectively. The expense ratio tends to fluctuate only slightly from period to period due to the maturity and 2015.scale of this segment.
Non-TraditionalFinancial Solutions - Asset-Intensive Reinsurance
Asset-Intensive reinsurance within the U.S. and Latin America Non-TraditionalFinancial Solutions segment primarily involves assuming investment risk within underlying annuities and corporate-owned life insurance policies. Most of these agreements are coinsurance, coinsurance with funds withheld or modco. The Company recognizes profits or losses primarily from the spread between the investment income earned and the interest credited on the underlying deposit liabilities, income associated with longevity risk, and fees associated with variable annuity account values and guaranteed investment contracts.
Impact of certain derivatives:
Income from the asset-intensive business tends to be volatile due to changes in the fair value of certain derivatives, including embedded derivatives associated with reinsurance treaties structured on a modco or funds withheld basis, as well as embedded derivatives associated with the Company’s reinsurance of equity-indexed annuities and variable annuities with guaranteed minimum benefit riders. Fluctuations occur period to period primarily due to changing investment conditions including, but not limited to, interest rate movements (including risk-free rates and credit spreads), implied volatility, the Company’s own credit risk and equity market performance, all of which are factors in the calculations of fair value. Therefore, management believes it is helpful to distinguish between the effects of changes in these derivatives, net of related hedging activity, and the primary factors that drive profitability of the underlying treaties, namely investment income, fee income (included in other revenues), and interest credited. These fluctuations are considered unrealized by management and do not affect current cash flows, crediting rates or spread performance on the underlying treaties.
The following table summarizes the asset-intensive results and quantifies the impact of these embedded derivatives for the periods presented. Revenues before certain derivatives, benefits and expenses before certain derivatives, and income before income taxes and certain derivatives, should not be viewed as substitutes for GAAP revenues, GAAP benefits and expenses, and GAAP income before income taxes.

The changes in derivatives discussed above are considered unrealized by management and do not affect current cash flows, crediting rates or spread performance on the underlying treaties. Fluctuations occur period to period primarily due to changing investment conditions including, but not limited to, interest rate movements (including benchmark rates and credit spreads), credit valuation adjustments, implied volatility and equity market performance, all of which are factors in the calculations of fair value. Therefore, management believes it is helpful to distinguish between the effects of changes in these derivatives and the primary factors that drive profitability of the underlying treaties, namely investment income, fee income (included in other revenues) and interest credited.

Historically, the loss ratio increased primarily as the result of several large permanent level premium in force blocks assumed in 1997 and 1998. These blocks are mature blocks of long-term permanent level premium business in which mortality as a percentage of net premiums is expected to be higher than historical ratios. The nature of permanent level premium policies requires the Company to set up actuarial liabilities and invest the amounts received in excess of early-year claims costs to fund claims in later years when premiums, by design, continue to be level as compared to expected increasing mortality or claim costs. As such, investment income becomes a more significant component of profitability of these in force blocks.

Overall, while these ratios are expected to remain in a predictable range, they may fluctuate from period to period due to varying allowance levels and product mix. The decrease for the third quarter and first nine months reflects a lower level of creditor business which typically has a higher level of acquisition costs. In addition, the amortization patterns of previously capitalized amounts, which are subject to the form of the reinsurance agreement and the underlying insurance policies, may vary.
Other operating expenses decreased $1.7 million, or 17.3%, and $3.4 million, or 12.2%, for the three and nine months ended September 30, 2017, as compared to the same periods in 2016, primarily due to a decrease in corporate overhead expenses.

These increases are2016. The increase in the third quarter was primarily due to higher lapses from policies of the aforementioned closed block of business in Japan. The decrease in the first nine months is attributable to the aforementioned unfavorable lapse experience onlower lapses from policies from a closed block of business associated with a treaty in Japan.

The third quarter decrease was partially offset by a $7.6 million increase in investment income related to an increase in unallocated invested assets and higher investment yields, primarily due to a higher level of variable investment income. The decrease for the first nine months is primarily due to a decrease of $43.9 million in investment related gains (losses), net, mainly related to an increase in other-than-temporary impairments on fixed maturity securities and other impairment charges of $12.9 million and a reduction in net gains on the sale of investments of $25.2 million.

Liquidity and Capital Resources
Overview
The Company believes that cash flows from the source of funds available to it will provide sufficient cash flows for the next twelve months to satisfy the current liquidity requirements of RGA, Inc. and its subsidiaries under various scenarios that include the potential risk of early recapture of reinsurance treaties, market events and higher than expected claims. The Company performs periodic liquidity stress testing to ensure its asset portfolio includes sufficient high quality liquid assets that could be utilized to bolster its liquidity position under stress scenarios. These assets could be utilized as collateral for secured borrowing transactions with various third parties or by selling the securities in the open market if needed. The Company’s liquidity requirements have been and will continue to be funded through net cash flows from operations. However, in the event of significant unanticipated cash requirements beyond normal liquidity needs, the Company has multiple liquidity alternatives available based on market conditions and the amount and timing of the liquidity need. These alternatives include borrowings under committed credit facilities, secured borrowings, the ability to issue long-term debt, preferred securities or common equity and, if necessary, the sale of invested assets subject to market conditions.
Current Market Environment
The current interest rate environment in select markets, primarily the U.S. and Canada, continues to negatively affect the Company'sCompany’s earnings. TheHowever, the Company’s average investment yield, excluding spread business, decreased 24 basis pointshas begun to increase, which for the nine months ended September 30, 2016 as compared to2017 was 4.61%, 8 basis points above the same period in 2015.2016. The Company’s insurance liabilities, in particular its annuity products, are sensitive to changing market factors. Lower interest rates for the first six months of 2016 have significantly increased grossGross unrealized gains on fixed maturity and equity securities available-for-sale which totaled $3,578.3increased from $2,246.5 million and $1,947.0at December 31, 2016 to $2,651.5 million at September 30, 2016, and December 31, 2015, respectively. Similarly, gross2017. Gross unrealized losses decreased from $627.5$374.9 million at December 31, 20152016 to $137.3$163.2 million at September 30, 2016.2017.
The Company continues to be in a position to hold any investment security showing an unrealized loss until recovery, provided it remains comfortable with the credit of the issuer. As indicated above, gross unrealized gains on investment securities of $3,578.3$2,651.5 million remain well in excess of gross unrealized losses of $137.3$163.2 million as of September 30, 2016. Historically low interest rates continued to put pressure on the Company’s investment yield.2017. The Company does not rely on short-term funding or commercial paper and to date it has experienced no liquidity pressure, nor does it anticipate such pressure in the foreseeable future.
As a result of the June 23, 2016 referendum by British voters to exit the European Union (“Brexit”), global markets and foreign currencies have been adversely affected. In particular, the value of the British pound has sharply declined as compared to the U.S. dollar and other currencies. It is possible this volatility in foreign currencies could continue as the UK negotiates and executes its exit from the European Union. It is also possible that there will be greater restrictions, requirements and regulatory complexities on reinsurance provided in the UK by entities located outside the UK. These changes may adversely affect the Company’s operations and financial results.
The Company projects its reserves to be sufficient, and it would not expect to write down deferred acquisition costs or be required to take any actions to augment capital, even if interest rates remain at current levels for the next five years, assuming all other factors remain constant. While the Company has felt the pressures of sustained low interest rates and volatile equity markets and may continue to do so, its business operations are not overly sensitive to these risks. Although management believes the Company’s current capital base is adequate to support its business at current operating levels, it continues to monitor new business opportunities and any associated new capital needs that could arise from the changing financial landscape.

The undistributed earnings of substantially all of the Company’s foreign subsidiaries have been reinvested indefinitely in suchthose non-U.S. operations, as described in Note 9 - “Income Tax” of the Notes to Consolidated Financial Statements in the 20152016 Annual Report. Under current tax laws, should the Company repatriate such earnings, it may be subject to additional U.S. income taxes and foreign withholding taxes.
RGA endeavors to maintain a capital structure that provides financial and operational flexibility to its subsidiaries, credit ratings that support its competitive position in the financial services marketplace, and shareholder returns. As part of the Company’s capital deployment strategy, is has in recent years repurchased shares of RGA common stock and paid dividends to RGA shareholders, as authorized by the board of directors. RGA’s current share repurchase program, which was approved by the board of directors in January 2016,2017, authorizes the repurchase of up to $400.0 million of common stock. The pace of repurchase activity depends on various factors such as the level of available cash, an evaluation of the costs and benefits associated with alternative uses of excess capital, such as acquisitions and in force reinsurance transactions, and RGA’s stock price.

Debt
Certain of the Company’s debt agreements contain financial covenant restrictions related to, among others, liens, the issuance and disposition of stock of restricted subsidiaries, minimum requirements of consolidated net worth, maximum ratios of debt to capitalization and change of control provisions. The Company is required to maintain a minimum consolidated net worth, as defined in the debt agreements, of $3.5 billion, calculated as of the last day of each fiscal quarter. Also, consolidated indebtedness, calculated as of the last day of each fiscal quarter, cannot exceed 35% of the sum of the Company’s consolidated indebtedness plus adjusted consolidated stockholders'stockholders’ equity. A material ongoing covenant default could require immediate payment of the amount due, including principal, under the various agreements. Additionally, the Company’s debt agreements contain cross-default covenants, which would make outstanding borrowings immediately payable in the event of a material uncured covenant default under any of the agreements, including, but not limited to, non-payment of indebtedness when due for an amount in excess of $100.0 million, bankruptcy proceedings, or any other event which results in the acceleration of the maturity of indebtedness. As of September 30, 20162017 and December 31, 20152016, the Company had $3,111.3 million$2.8 billion and $2,312.6 million,$3.1 billion, respectively, in outstanding borrowings under its debt agreements and was in compliance with all covenants under those agreements. The ability of the Company to make debt principal and interest payments depends on the earnings and surplus of subsidiaries, investment earnings on undeployed capital proceeds, available liquidity at the holding company, and the Company’s ability to raise additional funds.
The Company enters into derivative agreements with counterparties that reference either the Company’s debt rating or its financial strength rating. If either rating is downgraded in the future, it could trigger certain terms in the Company’s derivative agreements, which could negatively affect overall liquidity. For the majority of the Company’s derivative agreements, there is a termination event, at the Company’s option, should the long-term senior debt ratings drop below either BBB+ (S&P) or Baa1 (Moody’s) or the financial strength ratings drop below either A- (S&P) or A3 (Moody’s).
In June 2016, RGA issued 3.95% Senior Notes due September 15, 2026 with a face amount of $400.0 million and 5.75% Fixed-To-Floating Rate Subordinated Debentures due June 15, 2056 with a face amount of $400.0 million. These securities have been registered with the Securities and Exchange Commission. The net proceeds from these offerings were approximately $791.0 million and will be used in part to repay upon maturity the Company’s $300.0 million 5.625% senior notes that mature in March 2017. The remainder will be used for general corporate purposes. Capitalized issue costs were approximately $9.0 million.
The Company may borrow up to $850.0 million in cash and obtain letters of credit in multiple currencies on a revolving credit facility that expires in September 2019. As of September 30, 20162017, the Company had no cash borrowings outstanding and $97.4$97.2 million in issued, but undrawn, letters of credit under this facility. As of September 30, 20162017 and December 31, 20152016, the average interest rate on short-term and long-term debt outstanding was 5.14%5.15% and 5.20%5.16%, respectively.

Based on the historic cash flows and the current financial results of the Company, management believes RGA’s cash flows will be sufficient to enable RGA to meet its obligations for at least the next 12 months.
Credit and Committed Facilities
At September 30, 2016,2017, the Company maintained an $850.0 million syndicated revolving credit facility and certain committed letter of credit facilities aggregating $890.3$1,349.1 million. See noteNote 13 - “Debt” in the Notes to Consolidated Financial Statements in the 20152016 Annual Report for further information about these facilities.
The Company has obtained bank letters of credit in favor of various affiliated and unaffiliated insurance companies from which the Company assumes business. These letters of credit represent guarantees of performance under the reinsurance agreements and allow ceding companies to take statutory reserve credits. Certain of these letters of credit contain financial covenant restrictions similar to those described in the “Debt” discussion above. At September 30, 2016,2017, there were approximately $217.5$133.4 million of outstanding bank letters of credit in favor of third parties. Additionally, in accordance with applicable regulations, the Company utilizes letters of credit to secure statutory reserve credits when it retrocedes business to its affiliated subsidiaries. The Company cedes business to its affiliates to help reduce the amount of regulatory capital required in certain jurisdictions, such as the U.S. and the UK. The Company believes the capital required to support the business in the affiliates reflects more realistic expectations than the original jurisdiction of the business, where capital requirements are often considered to be quite conservative. As of September 30, 2016, $907.9 million2017, $1.5 billion in letters of credit from various banks were outstanding, but undrawn, backing reinsurance between the various subsidiaries of the Company.
Cash Flows
The Company’s principal cash inflows from its reinsurance operations include premiums and deposit funds received from ceding companies. The primary liquidity concerns with respect to these cash flows are early recapture of the reinsurance contract by the ceding company and lapses of annuity products reinsured by the Company. The Company’s principal cash inflows from its invested assets result from investment income and the maturity and sales of invested assets. The primary liquidity concern with respect to

69

Table of Contents


these cash inflows relates to the risk of default by debtors and interest rate volatility. The Company manages these risks very closely. See “Investments” and “Interest Rate Risk” below.
Additional sources of liquidity to meet unexpected cash outflows in excess of operating cash inflows and current cash and equivalents on hand include selling short-term investments or fixed maturity securities and drawing funds under a revolving credit facility, under which the Company had availability of $752.6$752.8 million as of September 30, 2016.2017. The Company also has $838.3 million$1.1 billion of funds available through collateralized borrowings from the FHLB as of September 30, 2016.2017. As of September 30, 2016,2017, the Company could have borrowed these additional amounts without violating any of its existing debt covenants.
The Company’s principal cash outflows relate to the payment of claims liabilities, interest credited, operating expenses, income taxes, dividends to shareholders, purchases of treasury stock and principal and interest under debt and other financing obligations. The Company seeks to limit its exposure to loss on any single insured and to recover a portion of benefits paid by ceding reinsurance to other insurance enterprises or reinsurers under excess coverage and coinsurance contracts (See Note 2, “Summary of Significant Accounting Policies” ofin Notes to Consolidated Financial Statements in the Company's 20152016 Annual Report). The Company performs annual financial reviews of its retrocessionaires to evaluate financial stability and performance. The Company has never experienced a material default in connection with retrocession arrangements, nor has it experienced any difficulty in collecting claims recoverable from retrocessionaires; however, no assurance can be given as to the future performance of such retrocessionaires nor to the recoverability of future claims. The Company’s management believes its current sources of liquidity are adequate to meet its cash requirements for the next 12 months.

The Company’s asset-intensive products are primarily supported by investments in fixed maturity securities reflected on the Company’s balance sheet and under funds withheld arrangements with the ceding company. Investment guidelines are established to structure the investment portfolio based upon the type, duration and behavior of products in the liability portfolio so as to achieve targeted levels of profitability. The Company manages the asset-intensive business to provide a targeted spread between the interest rate earned on investments and the interest rate credited to the underlying interest-sensitive contract liabilities. The Company periodically reviews models projecting different interest rate scenarios and their effect on profitability. Certain of these asset-intensive agreements, primarily in the U.S. and Latin America Non-TraditionalFinancial Solutions operating segment, are generally funded by fixed maturity securities that are withheld by the ceding company.

The Company is a member of the FHLB and holds $51.8$67.9 million of FHLB common stock, which is included in other invested assets on the Company'sCompany’s condensed consolidated balance sheets. Membership provides the Company access to borrowing arrangements (“advances”) and funding agreements, discussed below, with the FHLB. RGA ReinsuranceThe Company did not have any advances from the FHLB at September 30, 20162017 and December 31, 2015.2016. The Company’s average outstanding balance of advances was $8.2 million and $17.0 million during the third quarter and the first nine months of 2017, respectively, and was $0.5 million and $29.5 million during the third quarter and the first nine months of 2016, respectively, and was $6.1 million and $10.7 million during the third quarter and the first nine months of 2015, respectively.

In addition, the Company has also entered into funding agreements with the FHLB under guaranteed investment contracts whereby the Company has issued the funding agreements in exchange for cash and for which the FHLB has been granted a blanket lien on the Company'sCompany’s commercial and residential mortgage-backed securities and commercial mortgage loans used to collateralize the Company'sCompany’s obligations under the funding agreements. The Company maintains control over these pledged assets, and may use, commingle, encumber or dispose of any portion of the collateral as long as there is no event of default and the remaining qualified collateral is sufficient to satisfy the collateral maintenance level. The funding agreements and the related security agreements represented by this blanket lien provide that upon any event of default by the Company, the FHLB'sFHLB’s recovery is limited to the amount of the Company'sCompany’s liability under the outstanding funding agreements. The amount of the Company'sCompany’s liability for the funding agreements with the FHLB under guaranteed investment contracts was $956.2 million$1.4 billion and $622.1 million$1.1 billion at September 30, 20162017 and December 31, 2015,2016, respectively, which is included in interest sensitive contract liabilities on the Company'sCompany’s condensed

The advances on these agreements are collateralized primarily by commercial and residential mortgage-backed securities, commercial mortgage loans, and U.S. Treasury and government agency securities. The amount of collateral exceeds the liability and is dependent on the type of assets collateralizing the guaranteed investment contracts.
Investments
Management of Investments
The Company’s investment and derivative strategies involve matching the characteristics of its reinsurance products and other obligations and to seek to closely approximate the interest rate sensitivity of the assets with estimated interest rate sensitivity of the reinsurance liabilities. The Company achieves its income objectives through strategic and tactical asset allocations, security and derivative strategies within an asset/liability management and disciplined risk management framework. Derivative strategies are employed within the Company’s risk management framework to help manage duration, currency, and other risks in assets and/or liabilities and to replicate the credit characteristics of certain assets. For a discussion of the Company’s risk management process see “Market and Credit Risk” in the “Enterprise Risk Management” section below.

The Company references rating agency designations in some of its investments disclosures. These designations are based on the ratings from nationally recognized statistical rating organizations, primarily those assigned by S&P. In instances where a S&P rating is not available the Company references the rating provided by Moody’s and in the absence of both the Company will assign equivalent ratings based on information from the NAIC. The NAIC assigns securities quality ratings and uniform valuations called “NAIC Designations” which are used by insurers when preparing their U.S. statutory filings. Structured securities (mortgage-backed and asset-backed securities) held by the Company'sCompany’s insurance subsidiaries that maintain the NAIC statutory basis of accounting utilize the NAIC rating methodology. The NAIC assigns designations to publicly traded as well as privately placed securities. The designations assigned by the NAIC range from class 1 to class 6, with designations in classes 1 and 2 generally considered investment grade (BBB or higher rating agency designation). NAIC designations in classes 3 through 6 are generally considered below investment grade (BB or lower rating agency designation).

The residential mortgage-backed securities include agency-issued pass-through securities and collateralized mortgage obligations. A majority of the agency-issued pass-through securities are guaranteed or otherwise supported by the Federal Home Loan Mortgage Corporation, Federal National Mortgage Association, or the Government National Mortgage Association. The principal risks inherent in holding mortgage-backed securities are prepayment and extension risks, which will affect the timing of when cash will be received and are dependent on the level of mortgage interest rates. Prepayment risk is the unexpected increase in principal payments from the expected, primarily as a result of owner refinancing. Extension risk relates to the unexpected slowdown in principal payments from the expected. In addition, non-agency mortgage-backed securities face credit risk should the borrower be unable to pay the contractual interest or principal on their obligation. The Company monitors its mortgage-backed securities to mitigate exposure to the cash flow uncertainties associated with these risks.
Asset-backed securities include credit card and automobile receivables, student loans, home equity loans and collateralized debt obligations (primarily collateralized loan obligations). The Company owns floating rate securities that represent approximately 12.4%

Table of Contents


14.0% and 12.9% of the total fixed maturity securities at September 30, 20162017 and December 31, 2015.2016, respectively. These investments have a higher degree of income variability than the other fixed income holdings in the portfolio due to the floating rate nature of the interest payments. The Company holds these investments to match specific floating rate liabilities primarily reflected in the condensed consolidated balance sheets as collateral finance notes, as well as to enhance asset management strategies. In addition to the risks associated with floating rate securities, principal risks in holding asset-backed securities are structural, credit and capital market risks. Structural risks include the securities’ cash flow priority in the capital structure and the inherent prepayment sensitivity of the underlying collateral. Credit risks include the adequacy and ability to realize proceeds from the collateral. Credit risks are mitigated by credit enhancements which include excess spread, over-collateralization and subordination. Capital market risks include general level of interest rates and the liquidity for these securities in the marketplace.
The Company monitors its fixed maturity and equity securities to determine impairments in value and evaluates factors such as financial condition of the issuer, payment performance, the length of time and the extent to which the market value has been below amortized cost, compliance with covenants, general market and industry sector conditions, current intent and ability to hold securities, and various other subjective factors. Based on management'smanagement’s judgment, securities determined to have an other-than-temporary impairment in value are written down to fair value. For the nine months ended September 30, 2016, other-than-temporary impairments on corporate and other fixed maturity securities related primarily to emerging market and high-yield debt exposures. See “Investments – Other-than-Temporary Impairment” in Note 2 – “Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements in the 20152016 Annual Report for additional information. The table below summarizes other-than-temporary impairments and changes in the mortgage loan provision for the three and nine months ended September 30, 20162017 and 20152016 (dollars in thousands).

The fixed maturity impairments for the three and nine months ended September 30, 20162017 and 20152016 were largely related to high-yield energycorporate securities. The equity impairments for the three and emerging market corporate securities.nine months ended September 30, 2017 were related to an equity position received as part of a debt restructuring. In addition, other impairment losses for the three and nine months ended September 30, 2017 and 2016 and September 30, 2015 are primarily due to impairments on limited partnerships and changes in the provision for equity release mortgages.

See “Unrealized Losses for Fixed Maturity and Equity Securities Available-for-Sale” in Note 4 – “Investments” in the Notes to Condensed Consolidated Financial Statements for a table that presents the total gross unrealized losses for fixed maturity and equity securities at September 30, 20162017 and December 31, 2015,2016, respectively, where the estimated fair value had declined and remained below amortized cost by less than 20% or more than 20%.
The Company’s determination of whether a decline in value is other-than-temporary includes analysis of the underlying credit and the extent and duration of a decline in value. The Company’s credit analysis of an investment includes determining whether the issuer is current on its contractual payments, evaluating whether it is probable that the Company will be able to collect all amounts due according to the contractual terms of the security and analyzing the overall ability of the Company to recover the amortized cost of the investment. In the Company’s impairment review process, the duration and severity of an unrealized loss position for equity securities are given greater weight and consideration given the lack of contractual cash flows and the deferability features of these securities.

Valuation allowances on mortgage loans are established based upon inherent losses expected by management to be realized in connection with future dispositions or settlement of mortgage loans, including foreclosures. The valuation allowances are established after management considers, among other things, the value of underlying collateral and payment capabilities of debtors. Any subsequent adjustments to the valuation allowances will be treated as investment gains or losses. See “Mortgage Loans on Real Estate” in Note 4 – “Investments” in the Notes to Condensed Consolidated Financial Statements for information regarding valuation allowances and impairments.
Policy Loans
Policy loans comprised approximately 3.0%2.6% and 3.4%3.1% of the Company’s cash and invested assets as of September 30, 20162017 and December 31, 2015,2016, respectively, the majority of which are associated with one client. These policy loans present no credit risk because the amount of the loan cannot exceed the obligation due the ceding company upon the death of the insured or surrender of the underlying policy. The provisions of the treaties in force and the underlying policies determine the policy loan interest rates. The Company earns a spread between the interest rate earned on policy loans and the interest rate credited to corresponding liabilities.

Funds Withheld at Interest
Funds withheld at interest comprised approximately 12.4%11.8% and 13.5%12.8% of the Company’s cash and invested assets as of September 30, 20162017 and December 31, 2015,2016, respectively. For reinsurance agreements written on a modified coinsurance basis and certain agreements written on a coinsurance basis, assets equal to the net statutory reserves are withheld and legally owned and managed by the ceding company, and are reflected as funds withheld at interest on the Company’s condensed consolidated balance sheets. In the event of a ceding company’s insolvency, the Company would need to assert a claim on the assets supporting its reserve liabilities. However, the risk of loss to the Company is mitigated by its ability to offset amounts it owes the ceding company for claims or allowances against amounts owed by the ceding company. Interest accrues to the total funds withheld at interest assets at rates defined by the treaty terms. Additionally, under certain treaties the Company is subject to the investment performance on the withheld assets, although it does not directly control them. These assets are primarily fixed maturity investment securities and pose risks similar to the fixed maturity securities the Company owns. To mitigate this risk, the Company helps set the investment guidelines followed by the ceding company and monitors compliance. Ceding companies with funds withheld at interest had an average financial strength rating of “A” at September 30, 20162017 and December 31, 2015.2016. Certain ceding companies maintain segregated portfolios for the benefit of the Company.
Other Invested Assets
Other invested assets include equity securities, limited partnership interests, joint ventures (other than operating joint ventures), structured loans, derivative contracts, FVO contractholder-directed unit-linked investments, FHLB common stock real estate held-for-investment and equity release mortgages. Other invested assets represented approximately 3.7%3.0% and 3.0%3.5% of the Company’s cash and invested assets as of September 30, 20162017 and December 31, 2015,2016, respectively. See “Other Invested Assets” in Note 4 – “Investments” in the Notes to Condensed Consolidated Financial Statements for a table that presents the carrying value of the Company’s other invested assets by type as of September 30, 20162017 and December 31, 2015.

2016.
The Company utilizes derivative financial instruments to protect the Company against possible changes in the fair value of its investment portfolio as a result of interest rate changes, to hedge against risk of changes in the purchase price of securities, to hedge liabilities associated with the reinsurance of variable annuities with guaranteed living benefits and to manage the portfolio’s effective yield, maturity and duration. In addition, the Company utilizes derivative financial instruments to reduce the risk associated with fluctuations in foreign currency exchange rates. The Company uses both exchange-traded, centrally cleared, and customized over-the-counter derivative financial instruments.
See Note 5 - “Derivative Instruments” in the Notes to Condensed Consolidated Financial Statements for a table that presents the notional amounts and fair value of investment related derivative instruments held at September 30, 20162017 and December 31, 2015.2016.
The Company may be exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments. Generally, the credit exposure of the Company’s derivative contracts is limited to the fair value at the reporting date plus or minus any collateral posted or held by the Company. The Company had no net credit exposure related to its derivative contracts, excluding futures and mortality swaps, at September 30, 2017 and December 31, 2016, as the net amount of collateral pledged to the Company from counterparties exceeded the fair value of the derivative contracts. The Company had credit exposure related to its derivative contracts, excluding futures and mortality swaps, of $7.8 million at December 31, 2015.
The Company manages its credit risk related to over-the-counter derivatives by entering into transactions with creditworthy counterparties, maintaining collateral arrangements and through the use of master agreements that provide for a single net payment to be made by one counterparty to another at each due date and upon termination. Certain of the Company'sCompany’s OTC derivatives are cleared derivatives, which are bilateral transactions between the Company and a counterparty where the transactions are cleared through a clearinghouse, such that each derivative counterparty is only exposed to the default of the clearinghouse. As exchange-tradedexchange-

traded futures are affected through regulated exchanges, and positions are marked to market on a daily basis, the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties. See Note 5 - “Derivative Instruments” in the Notes to Condensed Consolidated Financial Statements for more information regarding the Company’s derivative instruments.
Enterprise Risk Management
RGA maintains a dedicated Enterprise Risk Management (“ERM”) function that is responsible for analyzing and reporting the Company’s risks on an aggregated basis; facilitating monitoring to ensure the Company’s risks remain within its appetites limits and tolerances;limits; and ensuring, on an ongoing basis, that RGA’s ERM objectives are met. This includes ensuring proper risk controls are in place; risks are effectively identified, assessed, and managed; and key risks to which the Company is exposed are disclosed to appropriate stakeholders. The ERM function plays an important role in fostering the Company’s risk management culture and practices.

Enterprise Risk Management Structure and Governance
The Board of Directors (“the Board”) oversees enterprise risk through its standing committees. The Finance, Investments, and Risk Management (FIRM)(“FIRM”) Committee of the Board oversees the management of the Company’s ERM program and policies. The FIRM receives regular reports and assessments which describe the Company’s key risk exposures and include quantitative and qualitative assessments and information about breaches, exceptions, and waivers.
The Company’s Global Chief Risk Officer (“CRO”) leads the dedicated ERM function. The CRO reports to the PresidentChief Executive Officer (“CEO”) and has direct access to the Board through the FIRM Committee with formal reporting occurring quarterly. The CRO is supported by a network of Business Unit Chief Risk Officers and Risk Management Officers throughout the business who are responsible for the analysis and management of risks within their scope. A Lead Risk Management Officer is assigned to each risk to take overall responsibility to monitor and assess the risk consistently across all markets.
In addition to leading the ERM function, the CRO also chairs the Company’s Risk Management Steering Committee (“RMSC”), which is made up of senior management executives, including the Chief Executive Officer ("CEO"), the President,CEO, the Chief Financial Officer ("CFO"(“CFO”), and the Chief Operating Officer, among others. The RMSC approves targetsprovides oversight for the Insurance, Market and limitsCredit, Capital, and Operational risk committees and retains direct risk oversight responsibilities for each materialthe following:

In addition to the risk committees, at a consolidated level,their sub-committees and working groups, some of RGA’sRGA operating entities have risk management committees that oversee relevant risks relativerelated to segment-level risk targets and limits.
Enterprise Risk Management Framework
RGA’s ERM framework provides a platform to assess the risk / return profiles of risks throughout the organization to enable enhanced decision making by business leaders. The ERM framework also guides the development and implementation of mitigation strategies to reduce exposures to these risks to acceptable levels.
RGA’s ERM framework includes the following elements:
1.Risk Culture: Risk management is an integral part of the Company’s culture and is embedded in RGA’s business processes in accordance with RGA’s risk philosophy. As the cornerstone of the ERM framework, a culture of prudent risk management reinforced by senior management plays a preeminent role in the effective management of risks assumed by RGA.
2.Risk Tolerance Statements: DescribesAppetite Statement: A general and high level overview of the amount of risk profile RGA aims to achieve to meet its strategic objectives. This statement is then supported by more granular risk limits guiding the Company is willingbusinesses to accept, which take into account the interactions and aggregation of risks across multiple risk areas. These statements provide a framework for managing the Company from an overall risk point of view.achieve this Risk Appetite Statement.

3.Risk Targets and Limits: Risk Targets are established and managed in conjunction with strategic planning and set the desired range of risk that the Company seeks to assume. Risk Limits establish the maximum amount of eachdefined risk that the Company is willing to assume to remain within the Company’s overall risk tolerance.appetite. These risks have been identified by the management of the Company as relevant to manage the overall risk profile of the Company while allowing achievement of strategic objectives.
4.Risk Assessment Process: RGA uses qualitative and quantitative methods to assess key risks through a portfolio approach, which analyzes established and emerging risks in conjunction with other risks.
5.Business Specific Limits/Controls: These limits/controls provide additional safeguards against undesired risk exposures and are embedded in business processes. Examples include:include maximum retention limits, pricing and underwriting reviews, per issuer limits, concentration limits, and standard treaty language.
Proactive risk monitoring and reporting enable early detection and mitigation of emerging risks. The RMSC monitorsand its subcommittees monitor adherence to risk targets and limits through the ERM function, which reports regularly to the RMSC and FIRM Committee. The frequency of monitoring is tailored to the volatility assessment and relative priority of each risk. Risk escalation channels coupled with open communication lines enhance the mitigants explained above. The Company has devoted significant resources to developing its ERM program and expects to continue to do so in the future. Nonetheless, the Company’s policies and procedures to identify, manage, and monitor risks may not be fully effective. Many of the Company’s methods for managing risk are based on historical information, which may not be a good predictor of future risk exposures, such as the risk of a pandemic causing a large number of deaths. Management of operational, legal, and regulatory risk relies on policies and procedures which may not be fully effective under all scenarios.
Risk Categories
The Company categorizesgroups its main risks as insuranceinto the following categories: Insurance risk, marketMarket and Credit risk, creditCapital risk, Operational risk and operationalStrategic risk. Specific risk assessments and descriptions can be found below and in Item 1A - “Risk Factors” of the 20152016 Annual Report.

Insurance Risk
Insurance risk is the risk of losslower or negative earnings and potentially a reduction in enterprise value due to experience deviating adverselya greater amount of benefits and related expenses paid than expected, or from expectations for mortality, morbidity, longevity andnon-market related adverse policyholder behavior or lost future profits due to treaty recapture by clients.client behavior. The Company uses multiple approaches to managing insurance risk: active insurance risk assessment and pricing appropriately for the risks assumed, transferring undesired risks, and managing the retained exposure prudently. These strategies are explained below.
Insurance Risk Assessment and Pricing
The Company has developed extensive expertise in assessing insurance risks which ultimately forms an integral part of ensuring that it is compensated commensurately for the risks it assumes and that it does not overpay for the risks it transfers to third parties. This expertise includes a vast array of market and product knowledge supported by a large information database of historical experience which is closely monitored. Analysis and experience studies derived from this database help form the basis for the Company’s pricing assumptions which are used in developing rates for new risks. If actual mortality or morbidity experience is materially adverse, some reinsurance treaties allow for increases to future premium rates.
Misestimation of any key risk can threaten the long term viability of the enterprise. Further, the pricing process is a key operational risk and significant effort is applied to ensuring the appropriateness of pricing assumptions. Some of the safeguards the Company uses to ensure proper pricing are: experience studies, strict underwriting, sensitivity and scenario testing, pricing guidelines and controls, authority limits and internal and external pricing reviews. In addition, the ERM function provides pricing oversight which includes periodic pricing audits.
Specific stress scenarios and reverse stress tests are analyzed to better understand how the solvency and rating of the Company may be affected by specific events and to better understand the kind of events the Company's capital position can sustain.
Risk Transfer
To minimize volatility in financial results and reduce the impact of large losses, the Company transfers some of its insurance risk to third parties using vehicles such as retrocession and catastrophe coverage.
Individual Exposure Retrocession
In the normal course of business, the Company seeks to limit its exposure to loss on any single insured and to recover a portion of claims paid by ceding reinsurance to other insurance enterprises (or retrocessionaires) under excess coverage and coinsurance contracts. In individual life markets, the Company retains a maximum of $8.0 million of coverage per individual life. In certain limited situations the Company has retained more than $8.0 million per individual life. The Company enters into agreements with other reinsurers to mitigate the residual risk related to the over-retained policies. Additionally, due to some lower face amount reinsurance coverages provided by the Company in addition to individual life, such as group life, disability and health, under certain circumstances, the Company could potentially incur claims totaling more than $8.0 million per individual life.

Table of Contents


Catastrophic Excess Loss Retrocession
The Company seeks to limit its exposure to loss on its assumed catastrophic excess of loss reinsurance agreements by ceding a portion of its exposure to multiple retrocessionaires through retrocession line slips or directly to retrocession markets. The Company retainsCompany’s policy is to retain a maximum of $20.0 million of catastrophic loss exposure per agreement and retrocedesto retrocede up to $50.0$30.0 million additional loss exposures to the retrocession markets. The Company limits its exposure on a country-by-country (and state-by-state in the U.S.) basis by managing its total exposure to all catastrophic excess of loss agreements bound within a given country to established maximum aggregate exposures. The maximum exposures are established and managed both on gross amounts issued prior to including retrocession and for amounts net of exposures retroceded.
Catastrophe Coverage
The Company accesses the markets each year for annual catastrophic coverages and reviews current coverage and pricing of current and alternate designs. PurchasesThe coverage may vary from year to year based on the Company’s perceived value of such coverages.protection. The current policy covers events involving 8 or more insured deaths from a single occurrence and covers $100.0 million of claims in excess of the Company’s $25.0 million deductible.

Managing Retained Exposure
The Company retains most of the inbound insurance risk. The Company manages the retained exposure proactively using various mitigating factors such as diversification and limits. Diversification is the primary mitigating factor of short term volatility risk, but it also mitigates adverse impacts of changes in long term trends and catastrophic events. The Company’s insured populations are dispersed globally, diversifying the insurance exposure because factors that cause actual experience to deviate materially from expectations do not affect all areas uniformly and synchronously or in close sequence. A variety of limits mitigate retained insurance risk. Examples of these limits include geographic exposure limits, which set the maximum amount of business that can be written in a given locale,country, and jumbo limits, which prevent excessive coverage on a given individual.
In the event that mortality or morbidity experience develops in excess of expectations, some reinsurance treaties allow for increases to future premium rates. Other treaties include experience refund provisions, which may also help reduce RGA’s mortality risk.
RGA has various methods to manage its insurance risks, including access to the capital and reinsurance markets.
Market and Credit Risk
Market and Credit risk is the risk that netof lower or negative earnings and potentially a reduction in enterprise value due to changes in the market prices of asset and liability values or results of operations will be affected adversely by changes in market conditions such as market prices, exchange rates, and nominal interest rates. The Company is primarily exposed to interest rate, foreign currency, inflation, real estate and equity risks.liabilities.
Interest Rate Risk
Interest rateRate risk is the potential for loss, on a net asset and liability basis, due torisk that changes in the level and volatility of nominal interest rates including both risk-free rateaffect the profitability, value or solvency position of the Company. This includes credit spread changes and inflation but excludes credit spread changes.quality deterioration. This risk arises from many of the Company’s primary activities, as the Company invests substantial funds in interest-sensitive assets, primarily fixed maturity securities, and also has certain interest-sensitive contract liabilities. A prolonged period where market yields are significantly below the book yields of the Company'sCompany’s asset portfolio puts downward pressure on portfolio book yields. The Company has been proactive in its investment strategies, reinsurance structures and overall asset-liability management practices to reduce the risk of unfavorable consequences in this type of environment.
The Company manages interest rate risk to optimize the return on the Company’s capital and to preserve the value created by its business operations within certain constraints. For example, certain management and monitoring processes are designed to minimize the effect of sudden and/or sustained changes in interest rates on fair value, cash flows, and net interest income. The Company manages its exposure to interest rates principally by managing the relative matching of the cash flows of its liabilities and assets.
The Company’s exposure to interest rate price risk and interest rate cash flow risk is reviewed on a quarterly basis. Interest rate price risk exposure is measured using interest rate sensitivity analysis to determine the change in fair value of the Company’s financial instruments in the event of a hypothetical change in interest rates. Interest rate cash flow risk exposure is measured using interest rate sensitivity analysis to determine the Company’s variability in cash flows in the event of a hypothetical change in interest rates.
In order to reduce the exposure to changes in fair values from interest rate fluctuations, the Company has developed strategies to manage the net interest rate sensitivity of its assets and liabilities. In addition, from time to time, the Company has utilized the swap market to manage the sensitivity of fair values to interest rate fluctuations.
Inflation can also have direct effects on the Company’s assets and liabilities. The primary direct effect of inflation is the increase in operating expenses. A large portion of the Company’s operating expenses consists of salaries, which are subject to wage increases at least partly affected by the rate of inflation.

The Company reinsures annuities with benefits indexed to the cost of living. Some of these benefits are hedged with a combination of CPI swaps and indexed bonds when material.
Long Term Care products have an inflation component linked to the future cost of such services. If health care costs increase at a much larger rate than what is prevalent in the nominal interest rates available in the markets, the Company may not earn enough investment yield to pay future claims on such products.
Foreign Currency Risk
The CompanyForeign currency risk is subject to foreignthe risk of changes in level and volatility of currency translation, transaction, and net income exposure.exchange rates affect the profitability, value or solvency position of the Company. The Company manages its exposure to currency principally by currency matching invested assets with the underlying liabilities to the extent possible. The Company has in place net investment hedges for a portion of its investments in its Canadian operations to reduce excess exposure to these currencies. Translation differences resulting from translating foreign subsidiary balances to U.S. dollars are reflected in stockholders’ equity on the condensed consolidated balance sheets.
The Company generally does not hedge the foreign currency exposure of its subsidiaries transacting business in currencies other than their functional currency (transaction exposure). However, the Company has entered into cross currency swaps to manage exposure to specific currencies. The majority of the Company’s foreign currency transactions are denominated in Australian dollars, British pounds, Canadian dollars, Euros, Japanese yen, Korean won, and the South African rand. The maximum amount of assets held in a specific currency (with the exception of the U.S. dollar) is measured relative to risk targets and is monitored regularly.

Inflation Risk
The primary direct effect on the Company of inflation is the increase in operating expenses. A large portion of the Company’s operating expenses consists of salaries, which are subject to wage increases at least partly affected by the rate of inflation. The rate of inflation also has an indirect effect on the Company. To the extent that a government’s policies to control the level of inflation result in changes in interest rates, the Company’s investment income is affected.
The Company reinsures annuities with benefits indexed to the cost of living. Some of these benefits are hedged with a combination of CPI swaps and indexed bonds when material.
Long Term Care products have an inflation component linked to the future cost of such services. If health care costs increase at a much larger rate than what is prevalent in the nominal interest rates available in the markets, the Company may not earn enough yield to pay future claims on such products.
Real Estate Risk
Real Estate risk is the risk that changes in the level and volatility of real estate market valuations may impact the profitability, value or solvency position of the Company. The Company has investments in direct real estate equity and debt instruments collateralized by real estate (“real estate loans”). Real estate equity risks include significant reduction in valuations, which could be caused by downturns in the broad economy or in specific geographic regions or sectors. In addition, real estate loan risks include defaults, natural disasters, borrower or tenant bankruptcy and reduced liquidity. Real estate loan risks are partially mitigated by the excess of the value of the property over the loan principle, which provides a buffer should the value of the real estate decrease. The Company manages its real estate loan risk by diversifying by property type and geography and through exposure limits.
Equity Risk
Equity risk is the risk that net assetchanges in the level and liability (e.g. variable annuitiesvolatility of equity market valuations affect the profitability, value or solvency position of the company. This risk includes Variable Annuity and other equity linked exposures) values or revenues will be affected adversely by changes inexposures and asset related equity markets.exposure. The Company assumes equity risk from alternative investments, fixed indexed annuities and variable annuities. The Company uses derivatives to hedge its exposure to movements in equity markets that have a direct correlation with certain of its reinsurance products.
Alternative Investments
Alternative investments are investments in non-traditional asset classes that are most commonly backingprimarily back the Company’s capital and surplus. The Company generally restricts the alternative investments portfolio to non-liability supporting assets: that is, free surplus. For (re)insurance companies, alternativeAlternative investments generally encompass: hedge funds, owned commercial real estate, emerging markets debt, distressed debt, commodities, infrastructure, tax credits, and equities, both public and private. The Company mitigates its exposure to alternative investments by limiting the size of the alternative investments holding.holding and using per-issuer investment limits.
Fixed Indexed Annuities
The Company reinsures fixed indexed annuities ("FIAs"(“FIAs”). Credits for FIAs are affected by changes in equity markets. Thus the fair value of the benefit is primarily a function of primarily index returns and volatility. The Company hedges most of the underlying FIA equity exposure.exposure with derivatives.

Variable Annuities
The Company reinsures variable annuities including those with guaranteed minimum death benefits (“GMDB”), guaranteed minimum income benefits (“GMIB”), guaranteed minimum accumulation benefits (“GMAB”) and guaranteed minimum withdrawal benefits (“GMWB”). Strong equity markets, increases in interest rates and decreases in equity market volatility will generally decrease the fair value of the liabilities underlying the benefits. Conversely, a decrease in the equity markets along with a decrease in interest rates and an increase in equity market volatility will generally result in an increase in the fair value of the liabilities underlying the benefits, which has the effect of increasing reserves and lowering earnings. The Company maintains a customized dynamic hedging program that is designed to substantially mitigate the risks associated with income volatility around the change in reserves on guaranteed benefits, ignoring the Company’s own credit risk assessment. However, the hedge positions may not fully offset the changes in the carrying value of the guarantees due to, among other things, time lags, high levels of volatility in the equity and derivative markets, extreme swings in interest rates, unexpected contract holder behavior, and divergence between the performance of the underlying funds and hedging indices. These factors, individually or collectively, may have a material adverse effect on the Company’s net income, financial condition or liquidity. The table below provides a summary of variable annuity account values and the fair value of the guaranteed benefits as of September 30, 20162017 and December 31, 2015.

Credit Risk
Credit risk is the risk of loss due to counterparty (obligor, client, retrocessionaire, or partner) credit deterioration or unwillingness to meet its obligations. Credit risk has two forms: investment credit risk (asset default and credit migration) and insurance counterparty risk.

Investment Credit Risk
Investment credit risk, which includes default risk, is risk of loss due to credit quality deterioration of an individual financial investment,asset, derivative or non-derivative contract or instrument. Credit quality deterioration may or may not be accompanied by a ratings downgrade. Generally, the investment credit exposure for fixed maturity securitiesan asset is limited to the fair value, net of any collateral received, at the reporting date.
Investment Credit Risk
Investment credit risk is credit risk related to invested assets. The Company manages investment credit risk using per-issuer investment limits. In addition to per-issuer limits, the Company also limits the total amounts of investments per rating category. An automated compliance system checks for compliance for all investment positions and sends warning messages when there is a breach. The Company manages its credit risk related to over-the-counter derivatives by entering into transactions with creditworthy counterparties, maintaining collateral arrangements and through the use of master agreements that provide for a single net payment to be made by one counterparty to another at each due date and upon termination. Because futures are transacted through regulated exchanges, and positions are marked to market on a daily basis, the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties to such derivative instruments.
The Company enters into various collateral arrangements, which require both the posting and accepting of collateral in connection with its derivative instruments. Collateral agreements contain attachment thresholds that vary depending on the posting party’s financial strength ratings. Additionally, a decrease in the Company’s financial strength rating to a specified level results in potential settlement of the derivative positions under the Company’s agreements with its counterparties. A committee is responsible for setting rules and approving and overseeing all transactions requiring collateral. See “Credit Risk” in Note 5 - “Derivative Instruments” in the Notes to Condensed Consolidated Financial Statements for additional information on credit risk related to derivatives.
Insurance Counterparty Risk
Insurance counterpartyCounterparty risk is the potential for the Company to incur losses due to a client, retrocessionaire, or partner becoming distressed or insolvent. This includes run-on-the-bank risk and collection risk.
Run-on-the-Bank
The risk that a client’s in force block incurs substantial surrenders and/or lapses due to credit impairment, reputation damage or other market changes affecting the counterparty. Substantially higher than expected surrenders and/or lapses could result in inadequate in force business to recover cash paid out for acquisition costs.

Collection Risk
For clients and retrocessionaires, this includes their inability to satisfy a reinsurance agreement because the right of offset is disallowed by the receivership court; the reinsurance contract is rejected by the receiver, resulting in a premature termination of the contract; and/or the security supporting the transaction becomes unavailable to RGA.
The Company manages insurance counterparty risk by limiting the total exposure to a single counterparty and by only initiating contracts with creditworthy counterparties. In addition, some of the counterparties have set up trusts and letters of credit, reducing the Company’s exposure to these counterparties.

Generally, RGA’s insurance subsidiaries retrocede amounts in excess of their retention to certain other RGA Reinsurance, Parkway Re, RGA Barbados, RGA Americas, Rockwood Re, Manor Re, RGA Worldwide or RGA Atlantic.insurance subsidiaries. External retrocessions are arranged through the Company’s retrocession pools for amounts in excess of its retention. As of September 30, 2016,2017, all retrocession pool members in this excess retention pool rated by the A.M. Best Company were rated “A-” or better. A rating of “A-” is the fourth highest rating out of fifteensixteen possible ratings. For a majority of the retrocessionaires that were not rated, letters of credit or trust assets have been given as additional security. In addition, the Company performs annual financial and in force reviews of its retrocessionaires to evaluate financial stability and performance.
The Company has never experienced a material default in connection with retrocession arrangements, nor has it experienced any material difficulty in collecting claims recoverable from retrocessionaires; however, no assurance can be given as to the future performance of such retrocessionaires or as to the recoverability of any such claims.
Aggregate Counterparty Limits
In addition to investment credit limits and insurance counterparty limits, there are aggregate counterparty risk limits which include counterparty exposures from reinsurance, financing and investment activities at an aggregated level to control total exposure to a single counterparty. Counterparty risk aggregation is important because it enables the Company to capture risk exposures at a comprehensive level and under more extreme circumstances compared to analyzing the components individually.
All counterparty exposures are calculated on a quarterly basis, reviewed by management and monitored by the ERM function.
Operational RisksCapital Risk
Operational risks representCapital risk is the risk of loss,lower or lostnegative earnings and a potential reduction in enterprise value, and/or the ability to conduct business opportunities, due to inadequate or failed internal processes, people, or systems or due to external events. These risks are sometimes residual risks after insurance, market, and credit risks have been identified. Identified operational risks are divided into four areas and are evaluated through a quarterly qualitative assessment involving Risk Management Officers across RGA’s business units. The four areas include the following:
Process Risks
Process risks include known factors within the Company’s key operational processes (such as administration, claims, underwriting, investment operations, retrocession, pricing process, disruption of operations, information security, andinsufficient financial reporting) that could have potential effects on the Company’s ability to meet business objectives.
Legal/Regulatory Risks
Legal and regulatory risks include the various legal, compliance, sovereign, and regulatory obligations and concerns faced by the Company. This risk area often intersects with the Company's core operational process risk areas. Given the scope of the Company’s business and the number of countries in which it operates, this set of risks has the potential to affect the business locally, regionally, or globally.
Financial Risks
Financial risks take into account known factors related to fraud, collateral, expenses,capacity. Collateral, financing, liquidity and tax and valuation. There are many aspects to this set of risks that are important to the operations of the Company and its ability to meet obligations with its clients, shareholders and regulators.
Intangibles RisksOperational Risk
IntangiblesOperational risk is the risk of lower or negative earnings and a potential reduction in enterprise value caused by the inadequacy or failure of internal processes, people and systems, or from the adverse impact of external events or actors. The Company regularly monitors the risks includerelated to human capital, ratings, reputation,fraud, business conduct and strategy. Thesegovernance, disruption of operations, business operations and privacy and security related matters. Operational risks are core to managing the Company’s brand and market confidence as well as maintaining its ability to acquire and retain the appropriate expertise to execute and operate the business.
Strategic Risk
Strategic risk is the risk of lower or negative earnings and a potential reduction in enterprise value related to the planning, implementation, and management of the Company’s business plans and strategies. This includes the risks associated with the global environment in which it operates; future law and regulation changes; political and sovereign risks; and relationships with key external parties.
