Review by Independent Registered Public Accounting Firm

The March 31, 2015, and 2014, consolidated financial statements included in this filing have been reviewed by KPMG LLP, an independent registered public accounting firm, in accordance with established professional standards and procedures for such a review.

The report of KPMG LLP commenting upon its review is included on the following page.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Aflac Incorporated:

We have reviewed the consolidated balance sheet of Aflac Incorporated and subsidiaries (the Company) as of March 31, 2015, and the related consolidated statements of earnings, comprehensive income (loss), shareholders' equity and cash flows for the three-month periods ended March 31, 2015, and 2014. These consolidated financial statements are the responsibility of the Company's management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Aflac Incorporated and subsidiaries as of December 31, 2014, and the related consolidated statements of earnings, comprehensive income (loss), shareholders' equity and cash flows for the year then ended (not presented herein); and in our report dated February 26, 2015, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2014, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Notes to the Consolidated Financial Statements

(Interim period data – Unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business 

Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States and Japan. The Company's insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac), which operates in the United States (Aflac U.S.) and as a branch in Japan (Aflac Japan). American Family Life Assurance Company of New York (Aflac New York) is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. Additionally, Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. Our insurance operations in the United States and our branch in Japan service the two markets for our insurance business. Aflac Japan's revenues, including realized gains and losses on its investment portfolio, accounted for 70% and 75% of the Company's total revenues in the three-month periods ended March 31, 2015, and 2014, respectively. The percentage of the Company's total assets attributable to Aflac Japan was 82% at March 31, 2015 and December 31, 2014.

Basis of Presentation

We prepare our financial statements in accordance with U.S. generally accepted accounting principles (GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to GAAP issued by the FASB are derived from the FASB Accounting Standards Codification^TM (ASC). The preparation of financial statements in conformity with GAAP requires us to make estimates when recording transactions resulting from business operations based on currently available information. The most significant items on our balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments, deferred policy acquisition costs, liabilities for future policy benefits and unpaid policy claims, and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, mortality, morbidity, commission and other acquisition expenses, and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates will be revised and reflected in operating results. Although some variability is inherent in these estimates, we believe the amounts provided are adequate.

The unaudited consolidated financial statements include the accounts of the Parent Company, its subsidiaries and those entities required to be consolidated under applicable accounting standards. All material intercompany accounts and transactions have been eliminated.

In the opinion of management, the accompanying unaudited consolidated financial statements of the Company contain all adjustments, consisting of normal recurring accruals, which are necessary to fairly present the consolidated balance sheets as of March 31, 2015 and December 31, 2014, the consolidated statements of earnings, comprehensive income (loss), shareholder's equity and cash flows for the three-month periods ended March 31, 2015 and 2014. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, these financial statements should be read in conjunction with the financial statements and notes thereto included in our annual report to shareholders for the year ended December 31, 2014.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Income Statement - Extraordinary and Unusual Items - Simplifying income statement presentation by eliminating the concept of extraordinary items: In January 2015, the FASB issued updated guidance that eliminates from GAAP the concept of extraordinary items. Although the amendments will eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The amendments in this updated guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We

9

adopted this guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations.

Transfers and Servicing, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures: In June 2014, the FASB issued updated guidance for repurchase agreement and security lending transactions to change the accounting for repurchase-to-maturity transactions and linked repurchase financings to be accounted for as secured borrowings, consistent with the accounting for other repurchase agreements. The amendments also require new disclosures to increase transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. We adopted accounting changes for the new guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations. However, the disclosures in the new guidance are required and will be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015.

Accounting Pronouncements Pending Adoption

Interest - Imputation of Interest - Simplifying the presentation of debt issuance costs: In April 2015, FASB issued updated guidance to simplify presentation of debt issuance costs. The updated guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. The amendment is effective for annual periods and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Consolidation - Amendments to the consolidation analysis: In February 2015, the FASB issued updated guidance that affect evaluation of whether limited partnerships and similar legal entities (limited liability corporations and securitization structures, etc.) are variable interest entities (VIEs), evaluation of whether fees paid to a decision maker or a service provider are a variable interest, and evaluation of the effect of fee arrangements and the effect of related parties on the determination of the primary beneficiary under the VIE model for consolidation. The updated guidance eliminates the presumption that a general partner should consolidate a limited partnership. Limited partnership and similar legal entities that provide partners with either substantive kick-out rights or substantive participating rights (representing the partners’ controlling financial interest in the entity) over the general partner will now be evaluated under the voting interest model rather than the VIE model for consolidation. In regard to the fees paid to a decision maker or a service provider, the updated guidance eliminates three of the six criteria that an entity’s decision makers or service providers must meet for them to conclude that the fees do not represent a variable interest in that entity and, thus, should be excluded from the assessment for determining the primary beneficiary. Finally, in situations where no single party has a controlling financial interest in a VIE, the related party relationships under common control should be considered in their entirety in determining whether that common control group has a controlling financial interest in the VIE. However, if substantially all of the activities of the VIE are conducted on behalf of a single variable interest holder (excluding the decision maker) in a related party group that has the characteristics of a primary beneficiary, that single variable interest holder must consolidate the VIE as the primary beneficiary. The amendments in the updated guidance are effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017. Early application is permitted, including adoption in an interim period. We are evaluating whether the adoption of this guidance will have an impact on our financial position, results of operations or disclosures.

Derivatives and Hedging - Determining whether the host contract in a hybrid financial instrument issued in the form of a share is more akin to debt or equity: In November 2014, the FASB issued guidance to clarify how to evaluate the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. The guidance also clarifies that an entity should assess the substance of the relevant terms and features when considering how to weight those terms and features. The guidance is effective for annual periods and interim periods beginning after December 15, 2015. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Presentation of Financial Statements - Going Concern - Disclosure of uncertainties about an entity’s ability to continue as a going concern: In August 2014, the FASB issued this amendment that provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendment is

10

effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Compensation - Stock Compensation - Accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period: In June 2014, the FASB issued this amendment that provides guidance on certain share-based payment awards that require a specific performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Revenue from contracts with customers: In May 2014, the FASB issued updated guidance that affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Recent accounting guidance not discussed above is not applicable, did not have, or is not expected to have a material impact to our business. 

For additional information on new accounting pronouncements and recent accounting guidance and their impact, if any, on our financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014.

2. BUSINESS SEGMENT INFORMATION

The Company consists of two reportable insurance business segments: Aflac Japan and Aflac U.S., both of which sell supplemental health and life insurance. Operating business segments that are not individually reportable and business activities not included in Aflac Japan or Aflac U.S. are included in the "Other business segments" category.

We do not allocate corporate overhead expenses to business segments. We evaluate and manage our business segments using a financial performance measure called pretax operating earnings. Our definition of operating earnings includes interest cash flows associated with notes payable and excludes the following items from net earnings on an after-tax basis: realized investment gains/losses (securities transactions, impairments, and the impact of derivative and hedging activities), nonrecurring items and other non-operating income (loss). We then exclude income taxes related to operations to arrive at pretax operating earnings. Information regarding operations by segment follows:

The methods of determining the fair values of our investments in fixed-maturity securities, perpetual securities and equity securities are described in Note 5.

During the first quarter of 2015, we did not reclassify any investments from the held-to-maturity category to the available-for-sale category. During the first quarter of 2014, we reclassified one investment from the held-to-maturity category to the available-for-sale category as a result of the issuer being downgraded to below investment grade. At the time of transfer, the security had an amortized cost of $63 million and an unrealized loss of $8 million.

Contractual and Economic Maturities

The contractual maturities of our investments in fixed maturities at March 31, 2015, were as follows:

At March 31, 2015, the Parent Company had a portfolio of available-for-sale fixed-maturity securities totaling $476 million at amortized cost and $498 million at fair value, which is not included in the table above.

Expected maturities may differ from contractual maturities because some issuers have the right to call or prepay obligations with or without call premiums or prepayment penalties.

16

The majority of our perpetual securities are subordinated to other debt obligations of the issuer, but rank higher than the issuer's equity securities. Perpetual securities have characteristics of both debt and equity investments, along with unique features that create economic maturity dates for the securities. Although perpetual securities have no contractual maturity date, they have stated interest coupons that were fixed at their issuance and subsequently change to a floating short-term interest rate after some period of time. The instruments are generally callable by the issuer at the time of changing from a fixed coupon rate to a new variable rate of interest, which is determined by the combination of some market index plus a fixed amount of basis points. The net effect is to create an expected maturity date for the instrument. The economic maturities of our investments in perpetual securities, which were all reported as available for sale at March 31, 2015, were as follows:

	Aflac Japan						Aflac U.S.
(In millions)	Amortized Cost			Fair Value			Amortized Cost			Fair   Value

Investment Concentrations

Our process for credit-related investments begins with an independent approach to underwriting each issuer's fundamental credit quality. We evaluate independently those factors which we believe could influence an issuer's ability to make payments under the contractual terms of our instruments. This includes a thorough analysis of a variety of items including the issuer's country of domicile (including political, legal, and financial considerations); the industry in which the issuer competes (with an analysis of industry structure, end-market dynamics, and regulation); company specific issues (such as management, assets, earnings, cash generation, and capital needs); and contractual provisions of the instrument (such as financial covenants and position in the capital structure). We further evaluate the investment considering broad business and portfolio management objectives, including asset/liability needs, portfolio diversification, and expected income.

Banks and Financial Institutions

One of our largest investment sector concentrations as of March 31, 2015, was banks and financial institutions. Within the countries we approve for investment opportunities, we primarily invest in financial institutions that are strategically crucial to each approved country's economy. The bank and financial institution sector is a highly regulated industry and plays a strategic role in the global economy.

Our total investments in the bank and financial institution sector, including those classified as perpetual securities, were as follows:

Other-than-temporary Impairment

The fair values of our debt and perpetual security investments fluctuate based on changes in interest rates, foreign exchange, and credit spreads in the global financial markets. Fair values can also be heavily influenced by the values of the assets of the issuer and expected ultimate recovery values upon default, bankruptcy or other financial restructuring. Credit spreads are most impacted by the general credit environment and global market liquidity. Interest rates are driven by numerous factors including, but not limited to, supply and demand, governmental monetary actions, expectations of inflation and economic growth. We believe that fluctuations in the fair values of our investment securities related to general changes in the level of credit spreads or interest rates have little bearing on underlying credit quality of the issuer, and whether our investment is ultimately recoverable. Generally, we consider such declines in fair values to be temporary even in situations where an investment remains in an unrealized loss position for a year or more.

18

However, in the course of our credit review process, we may determine that it is unlikely that we will recover our investment in an issuer due to factors specific to an individual issuer, as opposed to general changes in global credit spreads or interest rates. In this event, we consider such a decline in the investment's fair value, to the extent it is below the investment's cost or amortized cost, to be an other-than-temporary impairment of the investment and reduce the book value of the investment to its fair value.

In addition to the usual investment risk associated with a debt instrument, our perpetual security holdings are largely issued by banks that are integral to the financial markets of the sovereign country of the issuer. As a result of the issuer's position within the economy of the sovereign country, our perpetual securities may be subject to a higher risk of nationalization of their issuers in connection with capital injections from an issuer's sovereign government. We cannot be assured that such capital support will extend to all levels of an issuer's capital structure. In addition, certain governments or regulators may consider imposing interest and principal payment restrictions on issuers of hybrid securities to preserve cash and preserve the issuer's capital. Beyond the cash flow impact that additional deferrals would have on our portfolio, such deferrals could result in ratings downgrades of the affected securities, which in turn could result in a reduction of fair value of the securities and increase our regulatory capital requirements. We consider these factors in our credit review process.

When determining our intention to sell a security prior to recovery of its fair value to amortized cost, we evaluate facts and circumstances such as, but not limited to, future cash flow needs, decisions to reposition our security portfolio, and risk profile of individual investment holdings. We perform ongoing analyses of our liquidity needs, which includes cash flow testing of our policy liabilities, debt maturities, projected dividend payments and other cash flow and liquidity needs. Our cash flow testing includes extensive duration analysis of our investment portfolio and policy liabilities. Based on our analyses, we have concluded that we have sufficient excess cash flows to meet our liquidity needs without selling any of our investments prior to their maturity.

Analysis of Securities in Unrealized Loss Positions

The unrealized losses on our investments have been primarily related to general market changes in interest rates, foreign exchange rates, and/or the levels of credit spreads rather than specific concerns with the issuer's ability to pay interest and repay principal.

For any significant declines in fair value, we perform a more focused review of the related issuers' credit profile. For corporate issuers, we evaluate their assets, business profile including industry dynamics and competitive positioning, financial statements and other available financial data. For non-corporate issuers, we analyze all sources of credit support, including issuer-specific factors. We utilize information available in the public domain and, for certain private placement issuers, from consultations with the issuers directly. We also consider ratings from the Nationally Recognized Statistical Rating Organizations (NRSROs), as well as the specific characteristics of the security we own including seniority in the issuer's capital structure, covenant protections, or other relevant features. From these reviews, we evaluate the issuers' continued ability to service our investment through payment of interest and principal.

Assuming no credit-related factors develop, as investments near maturity, unrealized gains and losses are expected to diminish. Based on our credit analysis, we believe that the issuers of our investments in the sectors shown in the table above have the ability to service their obligations to us.

Perpetual Securities

The majority of our investments in Upper Tier II and Tier I perpetual securities were in highly-rated global financial institutions. Upper Tier II securities have more debt-like characteristics than Tier I securities and are senior to Tier I securities, preferred stock, and common equity of the issuer. Conversely, Tier I securities have more equity-like characteristics, but are senior to the common equity of the issuer. They may also be senior to certain preferred shares, depending on the individual security, the issuer's capital structure and the regulatory jurisdiction of the issuer.

Details of our holdings of perpetual securities were as follows:

Assuming no credit-related factors develop, as investments near maturity, the unrealized gains or losses are expected to diminish. Based on our credit analysis, we believe that the issuers of our investments in these sectors have the ability to service their obligations to us.

Variable Interest Entities (VIEs)

As a condition to our involvement or investment in a VIE, we enter into certain protective rights and covenants that preclude changes in the structure of the VIE that would alter the creditworthiness of our investment or our beneficial interest in the VIE.

Our involvement with all of the VIEs in which we have an interest is passive in nature, and we are not the arranger of these entities. We have not been involved in establishing these entities, except as it relates to our review and evaluation of the structure of these VIEs in the normal course of our investment decision-making process. Further, we are not, nor have we been, required to purchase any securities issued in the future by these VIEs.

Our ownership interest in the VIEs is limited to holding the obligations issued by them. All of the VIEs in which we invest are static with respect to funding and have no ongoing forms of funding after the initial funding date. We have no direct or contingent obligations to fund the limited activities of these VIEs, nor do we have any direct or indirect financial guarantees related to the limited activities of these VIEs. We have not provided any assistance or any other type of financing support to any of the VIEs we invest in, nor do we have any intention to do so in the future. The weighted-average lives of our notes are very similar to the underlying collateral held by these VIEs where applicable.

Our risk of loss related to our interests in any of our VIEs is limited to our investment in the debt securities issued by them.

VIEs - Consolidated

The following table presents the amortized cost, fair value and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported.

Investments in Consolidated Variable Interest Entities

(In millions)	Amortized Cost			Fair Value			Amortized Cost			Fair Value
Assets:
Fixed maturities, available for sale		$	3,511		$	4,667		$	3,020		$	4,166

Liabilities:
Other liabilities		$	392		$	392		$	318		$	318
Total liabilities of consolidated VIEs		$	392		$	392		$	318		$	318

We are substantively the only investor in the consolidated VIEs listed in the table above. As the sole investor in these VIEs, we have the power to direct the activities of a variable interest entity that most significantly impact the entity's economic performance and are therefore considered to be the primary beneficiary of the VIEs that we consolidate. We also participate in substantially all of the variability created by these VIEs. The activities of these VIEs are limited to holding debt and perpetual securities and foreign currency and/or credit default swaps (CDSs), as appropriate, and utilizing the cash flows from these securities to service our investment. Neither we nor any of our creditors are able to obtain the underlying collateral of the VIEs unless there is an event of default or other specified event. For those VIEs that contain a swap, we are not a direct counterparty to the swap contracts and have no control over them. Our loss exposure to these VIEs is limited to our original investment. Our consolidated VIEs do not rely on outside or ongoing sources of funding to support their activities beyond the underlying collateral and swap contracts, if applicable. With the exception of our investment in senior secured bank loans through unit trust structures, the underlying collateral assets and funding of our consolidated VIEs are generally static in nature and the underlying collateral and the reference corporate entities covered by any CDS contracts were all investment grade at the time of issuance.

23

We are exposed to credit losses within any consolidated collateralized debt obligations (CDOs) that could result in principal losses to our investments. We have mitigated our risk of credit loss through the structure of the VIE, which contractually requires the subordinated tranches within these VIEs to absorb the majority of the expected losses from the underlying credit default swaps. We currently own only senior mezzanine CDO tranches. Based on our statistical analysis models and the current subordination levels in our CDOs, each of these VIEs can sustain a reasonable number of defaults in the underlying reference entities in the CDSs with no loss to our investment.

VIEs-Not Consolidated

The table below reflects the amortized cost, fair value and balance sheet caption in which our investment in VIEs not consolidated are reported.

Investments in Variable Interest Entities Not Consolidated

	March 31, 2015						December 31, 2014
(In millions)	Amortized Cost			Fair Value			Amortized Cost			Fair Value
Assets:
Fixed maturities, available for sale		$	6,159		$	7,089		$	6,104		$	6,937
Perpetual securities, available for sale		312			324			324			330
Fixed maturities, held to maturity		2,488			2,736			2,564			2,829
Total investments in VIEs not consolidated		$	8,959		$	10,149		$	8,992		$	10,096

The VIEs that we are not required to consolidate are investments that are in the form of debt obligations from the VIEs that are irrevocably and unconditionally guaranteed by their corporate parents or sponsors. These VIEs are the primary financing vehicles used by their corporate sponsors to raise financing in the international capital markets. The variable interests created by these VIEs are principally or solely a result of the debt instruments issued by them. We do not have the power to direct the activities that most significantly impact the entity's economic performance, nor do we have (1) the obligation to absorb losses of the entity or (2) the right to receive benefits from the entity. As such, we are not the primary beneficiary of these VIEs and are therefore not required to consolidate them. These VIE investments comprise securities from 180 separate issuers with an average credit rating of BBB.

Securities Lending

We lend fixed-maturity securities to financial institutions in short-term security-lending transactions. These short-term security-lending arrangements increase investment income with minimal risk. Our security lending policy requires that the fair value of the securities and/or unrestricted cash received as collateral be 102% or more of the fair value of the loaned securities.

These securities continue to be carried as investment assets on our balance sheet during the terms of the loans and are not reported as sales. We receive cash or other securities as collateral for such loans. For loans involving unrestricted cash or securities as collateral, the collateral is reported as an asset with a corresponding liability for the return of the collateral.

The following table presents our security loans outstanding and the corresponding collateral held:

(In millions)	March 31, 2015			December 31, 2014
Security loans outstanding, fair value		$	2,558		$	2,149
Cash collateral on loaned securities		2,615			2,193

Certain fixed-maturity securities have been pledged as collateral as part of derivative transactions. For additional information regarding pledged securities related to derivative transactions, see Note 4.

4. DERIVATIVE INSTRUMENTS

Our freestanding derivative financial instruments consist of: (1) foreign currency swaps and credit default swaps that are associated with investments in special-purpose entities, including VIEs where we are the primary beneficiary; (2) foreign currency forwards and options used in hedging foreign exchange risk on U.S. dollar-denominated securities in Aflac Japan's portfolio; (3) foreign currency forwards used to hedge certain portions of forecasted cash flows denominated in yen; (4) swaps associated with our notes payable, consisting of cross-currency interest rate swaps, also referred to as foreign currency swaps, associated with certain senior notes and our subordinated debentures; and (5) options on interest rate swaps (or interest rate swaptions) and futures used to hedge interest rate risk for certain available-for-sale securities. We do not use derivative financial instruments for trading purposes, nor do we engage in leveraged derivative transactions. Some of our derivatives are designated as cash flow hedges, fair value hedges or net investment hedges; however, other derivatives do not qualify for hedge accounting. We utilize a net investment hedge to mitigate foreign exchange exposure resulting from our net investment in Aflac Japan. In addition to designating derivatives as hedging instruments, we have designated our yen-denominated Samurai and Uridashi notes and yen-denominated loans as nonderivative hedging instruments for this net investment hedge.

Derivative Types

We enter into foreign currency swaps pursuant to which we exchange an initial principal amount in one currency for an initial principal amount of another currency, with an agreement to re-exchange the currencies at a future date at an agreed upon exchange rate. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Foreign currency swaps are used primarily in the consolidated VIEs in our Aflac Japan portfolio to convert foreign-denominated cash flows to yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. We also use foreign currency swaps to economically convert certain of our dollar-denominated senior note and subordinated debenture principal and interest obligations into yen-denominated obligations.

Foreign currency forwards and options with short-term maturities are executed for the Aflac Japan segment in order to hedge the currency risk on the fair value of certain fixed-maturity dollar-denominated securities. In forward transactions, Aflac Japan agrees with another party to buy a fixed amount of yen and sell a corresponding amount of U.S. dollars at a specified future date. Aflac Japan also executes foreign currency option transactions in a collar strategy, where Aflac Japan agrees with another party to simultaneously purchase a fixed amount of U.S. dollar put options and sell U.S. dollar call options. The combination of these two actions results in no net premium being paid (i.e. a costless or zero-cost collar). The foreign currency forwards and options are used in fair value hedging relationships to mitigate the foreign exchange risk associated with dollar-denominated investments supporting yen-denominated liabilities.

Foreign currency forwards are also used to hedge the currency risk associated with the net investment in Aflac Japan. In these forward transactions, Aflac agrees with another party to buy a fixed amount of U.S. dollars and sell a corresponding amount of yen at a specified future date.

Our CDS is used to assume credit risk related to an individual security. The only CDS derivative that we have entered into relates to components of an investment in a VIE. This CDS contract entitles the consolidated VIE to receive periodic fees in exchange for an obligation to compensate the derivative counterparties should the reference security issuers experience a credit event, as defined in the contract.

Interest rate swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. No cash or principal payments are exchanged at the inception of the contract. Interest rate swaps are primarily used to convert interest receipts on floating-rate fixed-maturity securities contracts to fixed rates. These derivatives are predominantly used to better match cash receipts from assets with cash disbursements required to fund liabilities.

Interest rate swaptions are options on interest rate swaps. Interest rate collars are combinations of two swaption positions and are executed in order to hedge certain dollar-denominated available-for-sale securities that are held in the Aflac Japan segment. We use collars to protect against significant changes in the fair value associated with interest rate changes of our dollar-denominated available-for-sale securities. In order to maximize the efficiency of the collars while minimizing cost, we set the strike price on each collar so that the premium paid for the ‘payer leg’ is offset by the premium received for having sold the ‘receiver leg’.

Periodically, depending on general economic conditions, we may enter into other derivative transactions.

25

Credit Risk Assumed through Derivatives

For the foreign currency and credit default swaps associated with our VIE investments for which we are the primary beneficiary, we bear the risk of foreign exchange loss due to counterparty default even though we are not a direct counterparty to those contracts. We are a direct counterparty to the foreign currency swaps that we have entered into in connection with certain of our senior notes, subordinated debentures, and Samurai notes; foreign currency forwards; foreign currency options; and interest rate swaptions, and therefore we are exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for our VIE swaps, foreign currency swaps, certain foreign currency forwards, foreign currency options and interest rate swaptions is mitigated by collateral posting requirements the counterparties to those transactions must meet. As of March 31, 2015, there were 16 counterparties to our derivative agreements, with five comprising 75% of the aggregate notional amount. The counterparties to these derivatives are financial institutions with the following credit ratings:

	March 31, 2015										December 31, 2014
(In millions)	Notional Amount of Derivatives			Asset Derivatives Fair Value			Liability Derivatives Fair Value				Notional Amount of Derivatives			Asset Derivatives Fair Value			Liability Derivatives Fair Value
Counterparties' credit rating:
AA		$	1,220		$	41		$	(51	)		$	1,098		$	39		$	(36	)
A		22,178			665			(548		)		22,564			763			(2,387		)
Total		$	23,398		$	706		$	(599	)		$	23,662		$	802		$	(2,423	)

We engage in derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annex (CSA) provisions, which generally provide for two-way collateral postings, in certain cases at the first dollar of exposure and in other cases once various rating and exposure threshold levels are triggered. We mitigate the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction or that additional collateral be posted upon the occurrence of certain events or circumstances. In addition, a significant portion of the derivative transactions have provisions that require collateral to be posted upon a downgrade of our long-term debt ratings or give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of collateral required to be posted to counterparties in the event of such downgrades, or the aggregate amount of payments that we could be required to make, depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade.

Collateral posted by us to third parties for derivative transactions was $87 million and $1.6 billion at March 31, 2015 and December 31, 2014, respectively, which consisted entirely of pledged securities. This collateral can generally be repledged or resold by the counterparties. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position by counterparty was $196 million and $2.1 billion as of March 31, 2015 and December 31, 2014, respectively. If the credit-risk-related contingent features underlying these agreements had been triggered on March 31, 2015, we estimate that we would be required to post a maximum of $109 million of additional collateral to these derivative counterparties. Collateral obtained by us from third parties for derivative transactions was $552 million and $619 million at March 31, 2015 and December 31, 2014, respectively. We generally can repledge or resell collateral obtained by us, although we do not typically exercise such rights.

Accounting for Derivative Financial Instruments

Freestanding derivatives are carried at estimated fair value in our consolidated balance sheets either as assets within other assets or as liabilities within other liabilities. See Note 5 for a discussion on how we determine the fair value of our derivatives. Accruals on derivatives are recorded in accrued investment income or within other liabilities in the consolidated balance sheets.

If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are generally reported within derivative and other gains(losses), which is a component of realized investment gains (losses). The fluctuations in estimated fair value of derivatives that have not been designated for hedge accounting can result in volatility in net earnings.

26

Hedge Documentation and Effectiveness Testing

To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated risk of the hedged item. At the inception of the hedging relationship, we formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking each hedge transaction. We document the designation of each hedge as either (i) a hedge of the variability of cash flows to be received or paid related to a recognized asset or liability or the hedge of a forecasted transaction ("cash flow hedge"); (ii) a hedge of the estimated fair value of a recognized asset or liability ("fair value hedge"); or (iii) a hedge of a net investment in a foreign operation. The documentation process includes linking derivatives and nonderivatives that are designated as hedges to specific assets or groups of assets or liabilities on the statement of financial position or to specific forecasted transactions and defining the effectiveness and ineffectiveness testing methods to be used. At the hedge's inception and on an ongoing quarterly basis, we also formally assess whether the derivatives that are used in hedging transactions have been, and are expected to continue to be, highly effective in offsetting their designated risk. Hedge effectiveness is assessed using qualitative and quantitative methods.

For assessing hedge effectiveness of cash flow hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression or other statistical analysis of changes in cash flows associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships on our VIE cash flow hedge is measured each reporting period using the “Hypothetical Derivative Method.” For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing hedge ineffectiveness are recognized in current earnings within derivative and other gains (losses). All components of each derivative's gain or loss are included in the assessment of hedge effectiveness.

For assessing hedge effectiveness of fair value hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression or other statistical analysis of changes in fair value associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships is measured each reporting period using the dollar offset method. For derivative instruments that are designated and qualify as fair value hedges, changes in the estimated fair value of the derivative, including amounts measured as ineffectiveness, and changes in the estimated fair value of the hedged item related to the designated risk being hedged, are reported in current earnings within derivative and other gains (losses).

For the hedge of our net investment in Aflac Japan, we have designated Parent Company yen-denominated liabilities as non-derivative hedging instruments and have designated certain foreign currency forwards and options as derivative hedging instruments. We make our net investment hedge designation at the beginning of each quarter. For assessing hedge effectiveness of net investment hedges, if the total of the designated Parent Company non-derivative and derivatives notional is equal to or less than our net investment in Aflac Japan, the hedge is deemed to be effective. If the hedge is effective, the related exchange effect on the yen-denominated liabilities is reported in the unrealized foreign currency component of other comprehensive income. For derivatives designated as net investment hedges, Aflac follows the forward-rate method. According to that method, all changes in fair value, including changes related to the forward-rate component of foreign currency forward contracts and the time value of foreign currency options, are reported in the unrealized foreign currency component of other comprehensive income. Should these designated net investment hedge positions exceed our net investment in Aflac Japan, the foreign exchange effect on the portion that exceeds our investment in Aflac Japan would be recognized in current earnings within derivative and other gains (losses).

Discontinuance of Hedge Accounting

We discontinue hedge accounting prospectively when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the estimated cash flows or fair value of a hedged item; (2) the derivative is de-designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised.

When hedge accounting is discontinued on a cash flow hedge or fair value hedge, the derivative is carried in the consolidated balance sheets at its estimated fair value, with changes in estimated fair value recognized in current period earnings. For discontinued cash flow hedges, including those where the derivative is sold, terminated or exercised, amounts previously deferred in other comprehensive income (loss) are reclassified into earnings when earnings are impacted by the cash flow of the hedged item.

27

Derivative Balance Sheet Classification

The tables below summarize the balance sheet classification of our derivative fair value amounts, as well as the gross asset and liability fair value amounts. The fair value amounts presented do not include income accruals. The notional amount of derivative contracts represents the basis upon which pay or receive amounts are calculated. Notional amounts are not reflective of credit risk.

Cash Flow Hedges

Certain of our consolidated VIEs have foreign currency swaps that qualify for hedge accounting treatment. For those that have qualified, we have designated the derivative as a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset (“cash flow” hedge). We expect to continue this hedging activity for a weighted-average period of approximately 11 years. The remaining derivatives in our consolidated VIEs that have not qualified for hedge accounting have been designated as held for other investment purposes (“non-qualifying strategies”).

Fair Value Hedges

We designate and account for certain foreign currency forwards and options as fair value hedges when they meet the requirements for hedge accounting. These foreign currency forwards and options hedge the foreign currency exposure of certain dollar-denominated fixed maturity securities within the investment portfolio of our Aflac Japan segment. We recognize gains and losses on these derivatives and the related hedged items in current earnings within derivative and other gains (losses). The change in the fair value of the foreign currency forwards related to the changes in the difference between the spot rate and the forward price is excluded from the assessment of hedge effectiveness. The change in fair value of the foreign currency option related to the time value of the option is excluded from the assessment of hedge effectiveness.

We designate and account for interest rate swaptions as fair value hedges when they meet the requirements for hedge accounting. These interest rate swaptions hedge the interest rate exposure of certain dollar-denominated fixed maturity securities within the investment portfolio of our Aflac Japan segment. We recognize gains and losses on these derivatives and the related hedged items in current earnings within derivative and other gains (losses). The change in the fair value of the interest rate swaptions related to the time value of the option is excluded from the assessment of hedge effectiveness.

Net Investment Hedge

Our primary exposure to be hedged is our net investment in Aflac Japan, which is affected by changes in the yen/dollar exchange rate. To mitigate this exposure, we have designated the Parent Company's yen-denominated liabilities (Samurai and Uridashi notes and yen-denominated loans - see Note 7) as nonderivative hedges and designated foreign currency forwards and, in prior periods, options as derivative hedges of the foreign currency exposure of our net investment in Aflac Japan.

We used foreign exchange forwards to economically hedge foreign exchange risk on 30.0 billion yen of profit repatriation received from Aflac Japan in February 2015. As of March 31, 2015, we had entered into foreign exchange forwards as part of an economic hedge on 157.5 billion yen of future profit repatriation.

Our net investment hedge was effective during the three-month periods ended March 31, 2015 and 2014.

Non-qualifying Strategies

For our derivative instruments in consolidated VIEs that do not qualify for hedge accounting treatment, all changes in their fair value are reported in current period earnings within derivative and other gains (losses). The amount of gain or loss recognized in earnings for our VIEs is attributable to the derivatives in those investment structures. While the change in value of the swaps is recorded through current period earnings, the change in value of the available-for-sale fixed-maturity or perpetual securities associated with these swaps is recorded through other comprehensive income.

We have cross-currency interest rate swap agreements related to our $400 million senior notes due February 2017, $550 million senior notes due March 2020, $350 million senior notes due February 2022, $700 million senior notes due June 2023, $750 million senior notes due November 2024, $450 million senior notes due March 2025, and $500 million subordinated debentures due September 2052. Changes in the values of these swaps are recorded through current period earnings.

For additional information regarding these swaps, see Note 7 in this report and Note 9 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014.

There was no gain or loss reclassified from accumulated other comprehensive income (loss) into earnings related to our designated cash flow hedges and net investment hedge for the three-month periods ended March 31, 2015 and 2014. As of March 31, 2015, deferred gains and losses on derivative instruments recorded in accumulated other comprehensive income that are expected to be reclassified to earnings during the next twelve months were immaterial.

Offsetting of Financial Instruments and Derivatives

Certain of the Company's derivative instruments are subject to enforceable master netting arrangements that provide for the net settlement of all derivative contracts between the Parent Company or Aflac and its respective counterparty in the event of default or upon the occurrence of certain termination events. Collateral support agreements with certain of the master netting arrangements provide that the Company will receive or pledge financial collateral in the event either minimum thresholds, or in certain cases ratings levels, have been reached.

We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities (see Note 3). When we have entered into securities lending agreements with the same counterparty, the agreements generally provide for net settlement in the event of default by the counterparty. This right of set-off would allow us to keep and apply collateral received if the counterparty failed to return the securities borrowed from us as contractually agreed.

31

The tables below summarize our derivatives and securities lending transactions, and as reflected in the tables, in accordance with GAAP, our policy is to not offset these financial instruments in the Consolidated Balance Sheets.

5. FAIR VALUE MEASUREMENTS

Fair Value Hierarchy

GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. These two types of inputs create three valuation hierarchy levels. Level 1 valuations reflect quoted market prices for identical assets or liabilities in active markets. Level 2 valuations reflect quoted market prices for similar assets or liabilities in an active market, quoted market prices for identical or similar assets or liabilities in non-active markets or model-derived valuations in which all significant valuation inputs are observable in active markets. Level 3 valuations reflect valuations in which one or more of the significant inputs are not observable in an active market.

33

The following tables present the fair value hierarchy levels of the Company's assets and liabilities that are measured and carried at fair value on a recurring basis.

Fair Value of Financial Instruments

U.S. GAAP requires disclosure of the fair value of certain financial instruments including those that are not carried at fair value. The carrying amounts for cash and cash equivalents, other investments, receivables, accrued investment income, accounts payable, cash collateral and payables for security transactions approximated their fair values due to the short-term nature of these instruments. Liabilities for future policy benefits and unpaid policy claims are not financial instruments as defined by GAAP.

Fixed maturities, perpetual securities, and equity securities

We determine the fair values of our fixed maturity securities, perpetual securities, and public and privately issued equity securities using the following approaches or techniques: price quotes and valuations from third party pricing vendors (including quoted market prices readily available from public exchange markets) and non-binding price quotes we obtain from outside brokers.

A third party pricing vendor has developed valuation models to determine fair values of privately issued securities to reflect the impact of the persistent economic environment and the changing regulatory framework. These models are discounted cash flow (DCF) valuation models, but also use information from related markets, specifically the CDS market to estimate expected cash flows. These models take into consideration any unique characteristics of the securities and make various adjustments to arrive at an appropriate issuer-specific loss adjusted credit curve.This credit curve is then used with the relevant recovery rates to estimate expected cash flows and modeling of additional features, including illiquidity adjustments, if necessary, to price the security by discounting those loss adjusted cash flows. In cases where a credit curve cannot be developed from the specific security features, the valuation methodology takes into consideration other market observable inputs, including: 1) the most appropriate comparable security(ies) of the issuer; 2) issuer-specific CDS spreads; 3) bonds or CDS spreads of comparable issuers with similar characteristics such as rating, geography, or sector; or 4) bond indices that are comparative in rating, industry, maturity and region.

The pricing data and market quotes we obtain from outside sources, including third party pricing services, are reviewed internally for reasonableness. If a fair value appears unreasonable, we will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, we may compare the inputs to relevant market indices

37

and other performance measurements. The output of this analysis is presented to the Company's Valuation and Classifications Subcommittee, or VCS. Based on the analysis provided to the VCS, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. We have performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value.

The fixed maturities classified as Level 3 consist of securities for which there are limited or no observable valuation inputs. For Level 3 securities that are investment grade, we estimate the fair value of these securities by obtaining non-binding broker quotes from a limited number of brokers. These brokers base their quotes on a combination of their knowledge of the current pricing environment and market conditions. We consider these inputs to be unobservable. For Level 3 investments that are below-investment-grade securities, we consider a variety of significant valuation inputs in the valuation process, including forward exchange rates, yen swap rates, dollar swap rates, interest rate volatilities, credit spread data on specific issuers, assumed default and default recovery rates, and certain probability assumptions. In obtaining these valuation inputs, we have determined that certain pricing assumptions and data used by our pricing sources are difficult to validate or corroborate by the market and/or appear to be internally developed rather than observed in or corroborated by the market. The use of these unobservable valuation inputs causes more subjectivity in the valuation process for these securities.

Historically, we have not adjusted the quotes or prices we obtain from the pricing services and brokers we use.

The following tables present the pricing sources for the fair values of our fixed maturities, perpetual securities, and equity securities.

The following is a discussion of the determination of fair value of our remaining financial instruments.

Derivatives

We use derivative instruments to manage the risk associated with certain assets. However, the derivative instrument may not be classified in the same fair value hierarchy level as the associated asset. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.

The fair values of the foreign currency forwards, options, and interest rate swaptions associated with certain fixed-maturity securities; the foreign currency forwards used to hedge certain portions of forecasted yen cash flows; and the foreign currency swaps associated with certain senior notes and our subordinated debentures are based on the amounts we would expect to receive or pay. The determination of the fair value of these derivatives is based on observable market inputs, therefore they are classified as Level 2.

For derivatives associated with VIEs where we are the primary beneficiary, we are not the direct counterparty to the swap contracts. As a result, the fair value measurements incorporate the credit risk of the collateral associated with the VIE. We receive valuations from a third party pricing vendor for these derivatives. Based on an analysis of these derivatives and a review of the methodology employed by the pricing vendor, we determined that due to the long duration of these swaps and the need to extrapolate from short-term observable data to derive and measure long-term inputs, certain inputs, assumptions and judgments are required to value future cash flows that cannot be corroborated by current inputs or current observable market data. As a result, the derivatives associated with our consolidated VIEs are classified as Level 3 of the fair value hierarchy.

Other policyholders' funds

The largest component of the other policyholders' funds liability is our annuity line of business in Aflac Japan. Our annuities have fixed benefits and premiums. For this product, we estimated the fair value to be equal to the cash surrender value. This is analogous to the value paid to policyholders on the valuation date if they were to surrender their policy. We periodically check the cash value against discounted cash flow projections for reasonableness. We consider our inputs for this valuation to be unobservable and have accordingly classified this valuation as Level 3.

Notes payable

The fair values of our publicly issued notes payable classified as Level 3 were obtained from a limited number of independent brokers. These brokers base their quotes on a combination of their knowledge of the current pricing environment and market conditions. We consider these inputs to be unobservable. The fair values of our yen-denominated loans approximate their carrying values.

The following is a discussion of the significant unobservable inputs or valuation technique used in determining the fair value of securities and derivatives classified as Level 3.

Net Asset Value

We hold certain unlisted equity securities whose fair value is derived based on the financial statements published by the investee. These securities do not trade on an active market and the valuations derived are dependent on the availability of timely financial reporting of the investee. Net asset value is an unobservable input in the determination of fair value ofequity securities.

Offered Quotes

In circumstances where our valuation model price is overridden because it implies a value that is not consistent with current market conditions, we will solicit bids from a limited number of brokers. We also receive unadjusted prices from brokers for our mortgage and asset-backed securities. These quotes are non-binding but are reflective of valuation best estimates at that particular point in time. Offered quotes are an unobservable input in the determination of fair value of mortgage- and asset-backed securities, certain banks/financial institutions, certain other corporate, and equity securities investments.

Interest Rates, CDS Spreads, Foreign Exchange Rates

The significant drivers of the valuation of the interest and foreign exchange swaps are interest rates, foreign exchange rates and CDS spreads. Our swaps have long maturities that increase the sensitivity of the swaps to interest rate fluctuations. Since most of our yen-denominated cross currency swaps are in a net liability position, an increase in interest rates will decrease the liabilities and increase the value of the swap.

Foreign exchange swaps also have a lump-sum final settlement of foreign exchange principal receivables at the termination of the swap. An increase in yen interest rates will decrease the value of the final settlement foreign exchange receivables and decrease the value of the swap, and an increase in USD interest rates increase the swap value.

A similar sensitivity pattern is observed for the foreign exchange rates. When the spot U.S. dollar/Japanese yen (USD/JPY) foreign exchange rate decreases and the swap is receiving a final exchange payment in JPY, the swap value will increase due to the appreciation of the JPY. Most of our swaps are designed to receive payments in JPY at the termination and will thus be impacted by the USD/JPY foreign exchange rate in this way. In cases where there is no final foreign exchange receivable in JPY and we are paying JPY as interest payments and receiving USD, a decrease in the foreign exchange rate will lead to a decrease in the swap value.

The extinguisher feature in most of our swaps results in a cessation of cash flows and no further payments between the parties to the swap in the event of a default on the referenced or underlying collateral. To price this feature, we apply the survival probability of the referenced entity to the projected cash flows. The survival probability uses the CDS spreads and recovery rates to adjust the present value of the cash flows. For extinguisher swaps with positive values, an increase in CDS spreads decreases the likelihood of receiving the final exchange payments and reduces the value of the swap.

Due to the long duration of these swaps and the need to extrapolate from short-term observable data to derive and measure long-term inputs, certain inputs, assumptions and judgments are required to value future cash flows that cannot be corroborated by current inputs or current observable market data.

Interest rates, CDS spreads, and foreign exchange rates are unobservable inputs in the determination of fair value of foreign currency swaps.

Base Correlations, CDS Spreads, Recovery Rates

Our CDOs are tranches on baskets of single-name credit default swaps. The risks in these types of synthetic CDOs come from the single-name CDS risk and the correlations between the single names. The valuation of synthetic CDOs is dependent on the calibration of market prices for interest rates, single name CDS default probabilities and base correlation using financial modeling tools. Since there is limited or no observable data available for these tranches, these base correlations must be obtained from commonly traded market tranches such as the CDX and

49

iTraxx indices. From the historical prices of these indices, base correlations can be obtained to develop a pricing curve of CDOs with different seniorities. Since the reference entities of the market indices do not match those in our portfolio underlying the synthetic CDO to be valued, several processing steps are taken to map the securities in our portfolio to the indices. With the base correlation determined and the appropriate spreads selected, a valuation is calculated. An increase in the CDS spreads in the underlying portfolio leads to a decrease in the value due to higher probability of defaults and losses. The impact on the valuation due to base correlation depends on a number of factors, including the riskiness between market tranches and the modeled tranche based on our portfolio and the equivalence between detachment points in these tranches. Generally speaking, an increase in base correlation will decrease the value of the senior tranches while increasing the value of junior tranches. This may result in a positive or negative value change.

The CDO tranches in our portfolio are junior tranches and, due to the low level of credit support for these tranches, exhibit equity-like behavior. As a result, an increase in recovery rates tends to cause their values to decrease.

Our interest rate swaps are linked to the underlying synthetic CDOs. The valuation of these swaps is performed using a similar approach to that of the synthetic CDOs themselves; that is, the base correlation model is used to ensure consistency between the synthetic CDOs and the swaps.

Base correlations, CDS spreads, and recovery rates are unobservable inputs in the determination of fair value of credit default swaps.

6. REINSURANCE

Effective March 31, 2015, we entered into a coinsurance reinsurance transaction whereby we ceded 30.0% of the sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business. We recorded the gain related to this transaction as a deferred profit liability on business sold through reinsurance on our consolidated balance sheets. The deferred profit liability of $600 million, as of March 31, 2015, included in future policy benefits in the consolidated balance sheet, is being amortized into income over the expected lives of the policies. The corresponding reinsurance recoverable is included in other assets in the consolidated balance sheet and totaled $600 million as of March 31, 2015. As of March 31, 2015, no ceded premiums or claims have been incurred or paid under the transaction.

Effective October 1, 2014 and September 30, 2013, we entered into coinsurance reinsurance transactions whereby we ceded 16.7% and 33.3%, respectively, of the hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business. We recorded the gain related to these transactions as a deferred profit liability on business sold through reinsurance on our consolidated balance sheets. The deferred profit liability of $684 million, as of March 31, 2015, included in future policy benefits in the consolidated balance sheet, is being amortized into income over the expected lives of the policies. The corresponding reinsurance recoverable is included in other assets in the consolidated balance sheet and totaled $707 million as of March 31, 2015.

Effective December 31, 2014, we entered into a retrocession coinsurance reinsurance transaction whereby we assumed 8.35% of the reinsured hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business through our subsidiary CAIC. The corresponding future policy benefit liability of $3 million, as of March 31, 2015, was included in future policy benefits in the consolidated balance sheet.

In March 2015, the Parent Company issued two series of senior notes totaling $1.0 billion through a U.S. public debt offering. The first series, which totaled $550 million, bears interest at a fixed rate of 2.40% per annum, payable semi-annually, and has a five-year maturity. The second series, which totaled $450 million, bears interest at a fixed rate of 3.25% per annum, payable semi-annually, and has a ten-year maturity. We have entered into cross-currency swaps that convert the dollar-denominated principal and interest on the senior notes into yen-denominated obligations which results in lower nominal net interest rates on the debt. By entering into these cross-currency swaps, we economically converted our $550 million liability into a 67.0 billion yen liability and reduced the interest rate on this debt from 2.40% in dollars to .24% in yen, and we economically converted our $450 million liability into a 55.0 billion yen liability and reduced the interest rate on this debt from 3.25% in dollars to .82% in yen.

In February 2015, the Parent Company and Aflac jointly entered into an uncommitted bank line of credit with a third party that provides for borrowings in the amount of $50 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expenses or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of March 31, 2015, we did not have any borrowings outstanding under our $50 million credit agreement.

The Parent Company and Aflac have an uncommitted bilateral line of credit that provides for borrowings in the amount of $100 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expense or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of March 31, 2015, we did not have any borrowings outstanding under our $100 million credit agreement. Borrowings under the financing agreement will mature no later than three months after the last drawdown date of October 15, 2015.

52

The Parent Company and Aflac have a senior unsecured revolving credit facility agreement with a syndicate of financial institutions that provides for borrowings in the amount of 50 billion yen. This credit agreement provides for borrowings in Japanese yen or the equivalent of Japanese yen in U.S. dollars on a revolving basis. Borrowings will bear interest at LIBOR plus the applicable margin of 1.125%. In addition, the Parent Company and Aflac are required to pay a facility fee of .125% on the commitments. As of March 31, 2015, we did not have any borrowings outstanding under our 50 billion yen revolving credit agreement. Borrowings under the credit agreement may be used for general corporate purposes, including a capital contingency plan for our Japanese operations. Borrowings under the financing agreement mature at the termination date of the credit agreement. The agreement requires compliance with certain financial covenants on a quarterly basis. This credit agreement will expire on the earlier of March 29, 2018, or the date of termination of the commitments upon an event of default as defined in the agreement.

We were in compliance with all of the covenants of our notes payable and lines of credit at March 31, 2015. No events of default or defaults occurred during the three-month period ended March 31, 2015.

9. SHARE-BASED COMPENSATION

As of March 31, 2015, the Company has outstanding share-based awards under two long-term incentive compensation plans.

The first plan, which expired in February 2007, is a stock option plan which allowed grants for incentive stock options (ISOs) to employees and non-qualifying stock options (NQSOs) to employees and non-employee directors. The options have a term of 10 years. The exercise price of options granted under this plan is equal to the fair market value of a share of the Company's common stock at the date of grant. Options granted before the plan's expiration date remain outstanding in accordance with their terms.

The second long-term incentive compensation plan allows awards to Company employees for ISOs, NQSOs, restricted stock, restricted stock units, and stock appreciation rights. Non-employee directors are eligible for grants of NQSOs, restricted stock, and stock appreciation rights. The ISOs and NQSOs have a term of 10 years, and the share-based awards generally vest based upon time-based conditions or time- and performance-based conditions. Time-based vesting generally occurs after three years. Performance-based vesting conditions generally include the attainment of goals related to Company financial performance. As of March 31, 2015, approximately 10.1 million shares were available for future grants under this plan, and the only performance-based awards issued and outstanding were restricted stock awards.

Share-based awards granted to U.S.-based grantees are settled with authorized but unissued Company stock, while those issued to Japan-based grantees are settled with treasury shares.

The following table provides information on stock options outstanding and exercisable at March 31, 2015.

	Stock Option Shares (in thousands)		Weighted-Average Remaining Term (in years)		Aggregate Intrinsic Value (in millions)			Weighted-Average Exercise Price Per Share
Outstanding		9,388		4.8		$	131		$	50.04
Exercisable		7,349		3.6		118			47.94

We received cash from the exercise of stock options in the amount of $22 million during the first three months of 2015, compared with $18 million in the first three months of 2014. The tax benefit realized as a result of stock option exercises and restricted stock releases was $15 million in the first three months of 2015, compared with $11 million in the first three months of 2014.

As of March 31, 2015, total compensation cost not yet recognized in our financial statements related to restricted stock awards was $64 million, of which $26 million (780 thousand shares) was related to restricted stock awards with a performance-based vesting condition. We expect to recognize these amounts over a weighted-average period of approximately 1.8 years. There are no other contractual terms covering restricted stock awards once vested.

For additional information on our long-term share-based compensation plans and the types of share-based awards, see Note 12 of the Notes to the Consolidated Financial Statements included in our annual report to shareholders for the year ended December 31, 2014.

10. BENEFIT PLANS

We have funded defined benefit plans in Japan and the United States, which cover substantially all of our full-time employees. Additionally, we maintain non-qualified, unfunded supplemental retirement plans that provide defined pension benefits in excess of limits imposed by federal tax law for certain Japanese, U.S. and former employees. Effective October 1, 2013, the U.S. tax-qualified defined benefit plan was frozen to new employees hired on or after October 1, 2013 and to employees rehired on or after October 1, 2013. U.S. employees who are not participants in the defined benefit plan receive a nonelective 401(k) employer contribution. Additionally, effective January 1, 2015, the U.S. non-qualified supplemental retirement plan was frozen to new participants.

We provide certain health care benefits for eligible U.S. retired employees, their beneficiaries and covered dependents ("other postretirement benefits"). The health care plan is contributory and unfunded. On October 1, 2013, a change was made to postretirement medical benefits to limit the eligibility for the benefits beginning January 1, 2014 to

56

include the following: (1) active employees whose age plus service, in years, equals or exceeds 80 (rule of 80); (2) active employees who are age 55 or older and have met the 15 years of service requirement; (3) active employees who will meet the rule of 80 in the next five years; (4) active employees who are age 55 or older and who will meet the 15 years of service requirement within the next five years; and (5) current retirees. Effective October 1, 2013, this change was accounted for as a negative plan amendment and resulted in a reduction to the postretirement benefit obligation of approximately $51 million, with an offset to accumulated other comprehensive income (AOCI). Starting in the fourth quarter of 2013, this reduction is being amortized as a reduction to net periodic benefit cost over three years. The postretirement plan obligation was remeasured using a discount rate of 4.75% as of October 1, 2013. For certain employees and former employees, additional coverage is provided for all medical expenses for life.

Pension and other postretirement benefit expenses, included in acquisition and operating expenses in the consolidated statement of earnings, included the following components:

	Three Months Ended March 31,
	Pension Benefits																Other
	Japan								U.S.								Postretirement Benefits
(In millions)	2015				2014				2015				2014				2015				2014

Net periodic (benefit) cost		$	5			$	5			$	12			$	10			$	(3	)		$	(3	)

During the three months ended March 31, 2015, Aflac Japan contributed approximately $5 million (using the weighted-average yen/dollar exchange rate for the three-month period ending March 31, 2015) to the Japanese funded defined benefit plan, and Aflac U.S. did not make a contribution to the U.S. funded defined benefit plan.

For additional information regarding our Japanese and U.S. benefit plans, see Note 14 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014.

11. COMMITMENTS AND CONTINGENT LIABILITIES

We are a defendant in various lawsuits considered to be in the normal course of business. Members of our senior legal and financial management teams review litigation on a quarterly and annual basis. The final results of any litigation cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, we believe the outcome of pending litigation will not have a material adverse effect on our financial position, results of operations, or cash flows.

12. SUBSEQUENT EVENTS

Effective April 1, 2015, we entered into a retrocession coinsurance reinsurance transaction whereby we assumed 90.0% of the reinsured sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business through our subsidiary CAIC. This business was originally ceded on March 31, 2015 as described in Note 6.

In April 2015, the Parent Company used the proceeds from the March 2015 issuance of its fixed-rate senior notes to redeem $850 million of our 8.50% fixed-rate senior notes due May 2019 and to pay a portion of the corresponding $230 million make-whole premium due to the investors of these notes.

MD&A OVERVIEW

Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to inform the reader about matters affecting the financial condition and results of operations of Aflac Incorporated and its subsidiaries for the three-month periods ended March 31, 2015 and 2014. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, the following discussion should be read in conjunction with the consolidated financial statements and notes that are included in our annual report to shareholders for the year ended December 31, 2014. This MD&A is divided into the following sections:

• Our Business

• Performance Highlights

• Critical Accounting Estimates

• Results of Operations, consolidated and by segment

• Analysis of Financial Condition, including discussion of market risks of financial instruments

• Capital Resources and Liquidity, including discussion of availability of capital and the sources and uses of cash

OUR BUSINESS

Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States and Japan. The Company’s insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac), which operates in the United States (Aflac U.S.) and as a branch in Japan (Aflac Japan). Most of Aflac’s policies are individually underwritten and marketed through independent agents. Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. Our insurance operations in the United States and our branch in Japan service the two markets for our insurance business.

PERFORMANCE HIGHLIGHTS

Yen-denominated income statement accounts are translated to U.S. dollars using a weighted-average Japanese yen/U.S. dollar foreign exchange rate, while yen-denominated balance sheet accounts are translated to U.S. dollars using a spot Japanese yen/U.S. dollar foreign exchange rate. The spot yen/dollar exchange rate at March 31, 2015 was 120.17, or 14.4%weaker than the spot yen/dollar exchange rate of 102.92 for the same period in 2014. The weighted-average yen/dollar exchange rate for the three-month period ended March 31, 2015 was 119.16, or 13.8%weaker than the weighted-average yen/dollar exchange rate of 102.70 for the same period in 2014.

Reflecting the weaker yen/dollar exchange rate, revenues were $5.2 billion in the first quarter of 2015, compared with $5.6 billion in the first quarter of 2014. Net earnings were $663 million, or $1.51 per diluted share, compared with $732 million, or $1.60 per diluted share, in the first quarter of 2014.

Results in the first quarter of 2015 included pretax net realized investment gains of $13 million ($8 million after-tax), compared with net realized investment losses of $46 million ($30 million after-tax) in the first quarter of 2014. Net investment gains in the first quarter of 2015 included $6 million ($4 million after-tax) of other-than-temporary impairment losses; $68 million of net gains ($44 million after-tax) from the sale or redemption of securities; and $49 million of net losses ($32 million after-tax) from valuing derivatives.

Shareholders’ equity included a net unrealized gain on investment securities and derivatives of $5.0 billion at March 31, 2015, compared with a net unrealized gain of $4.7 billion at December 31, 2014.

In March 2015, the Parent Company issued $1.0 billion of senior notes through a U.S. public debt offering. We entered into cross-currency interest rate swaps to economically convert the dollar-denominated principal and interest on the senior notes we issued into yen-denominated obligations. In February 2015, the Parent Company and Aflac jointly entered into an uncommitted bank line of credit with a third party that provides for borrowings in the amount of $50 million. For further information regarding these transactions, see Note 7 of the Notes to the Consolidated Financial Statements and the Capital Resources and Liquidity section of this MD&A.

In the first three months of 2015, we repurchased 9.8 million shares of our common stock in the open market for $600 million under our share repurchase program.

59

CRITICAL ACCOUNTING ESTIMATES

We prepare our financial statements in accordance with U.S. generally accepted accounting principles (GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In this MD&A, references to GAAP issued by the FASB are derived from the FASB Accounting Standards Codification^™(ASC). The preparation of financial statements in conformity with GAAP requires us to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that we deem to be most critical to an understanding of Aflac’s results of operations and financial condition are those related to the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits and unpaid policy claims, and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management’s analyses and judgments. The application of these critical accounting estimates determines the values for which 93% of our assets and 74% of our liabilities are reported as of March 31, 2015, and thus has a direct effect on net earnings and shareholders’ equity. Subsequent experience or use of other assumptions could produce significantly different results.

There have been no changes in the items that we have identified as critical accounting estimates during the three months ended March 31, 2015. For additional information, see the Critical Accounting Estimates section of MD&A included in our annual report to shareholders for the year ended December 31, 2014.

New Accounting Pronouncements

For information on new accounting pronouncements and the impact, if any, on our financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements.

RESULTS OF OPERATIONS

The following discussion includes references to our performance measures, operating earnings and operating earnings per diluted share, that are not based on accounting principles generally accepted in the United States of America (“GAAP”). Operating earnings is the measure of segment profit or loss we use to evaluate segment performance and allocate resources. Consistent with GAAP accounting guidance for segment reporting, operating earnings is our measure of segment performance. Aflac believes that an analysis of operating earnings is vitally important to an understanding of our underlying profitability drivers and trends of our insurance business. Furthermore, because a significant portion of our business is conducted in Japan, we believe it is equally important to understand the impact of translating Japanese yen into U.S. dollars.

Aflac defines operating earnings (a non-GAAP financial measure) as the profits derived from operations. Operating earnings includes interest cash flows associated with notes payable but excludes items that cannot be predicted or that are outside of management's control, such as realized investment gains and losses from securities transactions, impairments, and derivative and hedging activities; nonrecurring items; and other non-operating income (loss) from net earnings. Aflac's derivative activities are primarily used to hedge foreign exchange and interest rate risk in our investment portfolio as well as manage foreign exchange risk for certain notes payable and forecasted cash flows denominated in yen. Our management uses operating earnings to evaluate the financial performance of Aflac’s insurance operations because realized gains and losses from securities transactions, impairments, and derivative and hedging activities, as well as other and nonrecurring items, tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with the Company’s insurance operations, and therefore may obscure the underlying fundamentals and trends in Aflac’s insurance operations.

The following table is a reconciliation of items impacting operating and net earnings and operating and net earnings per diluted share.

Realized Investment Gains and Losses

Our investment strategy is to invest in fixed-maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s growth and profitability. This investment strategy incorporates asset-liability matching (ALM) to align the expected cash flows of the portfolio to the needs of the Company's liability structure. We do not purchase securities with the intent of generating capital gains or losses. However, investment gains and losses may be realized as a result of changes in the financial markets and the creditworthiness of specific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of our insurance products, which are the principal drivers of our profitability.

Securities Transactions and Impairments

During the three-month period ended March 31, 2015, we realized pretax investment gains, net of losses, of $68 million ($44 million after-tax) from sales and redemptions of securities. We realized pretax investment losses of $6 million($4 million after-tax) as a result of the recognition of other-than-temporary impairment losses on certain securities.

During the three-month period ended March 31, 2014, we realized pretax investment gains, net of losses, of $41 million ($27 million after-tax) from sales and redemptions of securities. We realized pretax investment losses of $3 million ($2 million after-tax) as a result of the recognition of other-than-temporary impairment losses on certain securities.

See Note 3 of the Notes to Consolidated Financial Statements for a more detailed discussion of these investment activities.

The following table details our pretax impairment losses by investment category.

	Three Months Ended March 31,

Bank/financial institution bonds	4		0
Total other-than-temporary impairment losses realized (1)	$	6	$	3

⁽¹⁾ Includes $6 and $3 for the three-month periods ended March 31, 2015 and 2014, respectively, from change in intent to sell securities

61

Impact of Derivative and Hedging Activities

Our derivative activities include foreign currency swaps and credit default swaps in VIEs that are consolidated; foreign currency forwards and options, interest rate swaptions and futures on certain fixed-maturity securities; foreign currency forwards and options that hedge certain portions of forecasted cash flows denominated in yen; and foreign currency swaps associated with certain senior notes and our subordinated debentures. During the three-month period ended March 31, 2015, we realized pretax investment losses, net of gains, of $49 million ($32 million after-tax), compared with pretax investment losses, net of gains, of $84 million ($55 million after-tax) for the same period in 2014, as a result of valuing these derivatives, net of the effects of hedge accounting. For a description of other items that could be included in the Impact of Derivative and Hedging Activities, see the Hedging Activities subsection of MD&A and Note 4 of the accompanying Notes to the Consolidated Financial Statements.

For additional information regarding realized investment gains and losses, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.

Foreign Currency Translation

Aflac Japan’s premiums and most of its investment income are received in yen. Claims and expenses are paid in yen, and we have yen-denominated assets that support yen-denominated policy liabilities. These and other yen-denominated financial statement items are translated into dollars for financial reporting purposes. We translate Aflac Japan’s yen-denominated income statement into dollars using an average exchange rate for the reporting period, and we translate its yen-denominated balance sheet using the exchange rate at the end of the period.

Due to the size of Aflac Japan, where our functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on our reported results. In periods when the yen weakens, translating yen into dollars results in fewer dollars being reported. When the yen strengthens, translating yen into dollars results in more dollars being reported. Consequently, yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. As a result, we view foreign currency translation as a financial reporting issue for Aflac rather than an economic event to our Company or shareholders. Because changes in exchange rates distort the growth rates of our operations, management evaluates Aflac’s financial performance excluding the impact of foreign currency translation.

Income Taxes

Our combined U.S. and Japanese effective income tax rate on pretax earnings was 34.5% for the three-month period ended March 31, 2015, compared with 33.7% for the same period in 2014.

Earnings Guidance

Our objective for 2015 is to increase operating earnings per diluted share by 2% to 7% compared with 2014, excluding the effect of foreign currency translation. Interest rates in both Japan and the United States are at historic lows, making it more difficult to invest cash flows at attractive yields. In April 2015, we executed a make-whole transaction to enhance our consolidated capital position (see the Capital Resources and Liquidity section of this MD&A for further discussion). As a result of this transaction, we will incur a non-operating charge of approximately $.34 to operating earnings per diluted share in the second quarter of 2015. However, operating earnings per diluted share will benefit by approximately $.07 for the full year 2015 due to a net reduction in interest expense. If we achieve our objective for 2015, the following table shows the likely results for operating earnings per diluted share, including the impact of foreign currency translation using various yen/dollar exchange rate scenarios.

2015 Operating Earnings Per Diluted Share Scenarios⁽¹⁾

⁽²⁾Actual 2014 weighted-average exchange rate

Assuming we achieve our earnings objective and the yen/dollar exchange rate averages 120 to 125, we would expect to report operating earnings of $5.74 to $6.15 per diluted share for the full year of 2015. Additionally, for the second quarter of 2015, using the same currency assumptions, we would expect operating earnings in the range of $1.46 to $1.57 per diluted share.

INSURANCE OPERATIONS

Aflac's insurance business consists of two segments: Aflac Japan and Aflac U.S. Aflac Japan, which operates as a branch of Aflac, is the principal contributor to consolidated earnings. GAAP financial reporting requires that a company report financial and descriptive information about operating segments in its annual and interim period financial statements. Furthermore, we are required to report a measure of segment profit or loss, certain revenue and expense items, and segment assets.

We evaluate our sales efforts using new annualized premium sales, an industry operating measure. New annualized premium sales, which include both new sales and the incremental increase in premiums due to conversions, represent the premiums that we would collect over a 12-month period, assuming the policies remain in force. For Aflac Japan, new annualized premium sales are determined by applications submitted during the reporting period. For Aflac U.S., new annualized premium sales are determined by applications that are issued during the reporting period.

Annualized premiums in force increased 1.4% to 1.60 trillion yen as of March 31, 2015, compared with 1.58 trillion yen as of 2014. The increase in annualized premiums in force in yen reflects the sales of new policies combined with the high persistency of Aflac Japan's business. Annualized premiums in force, translated into dollars at respective period-end exchange rates, were $13.3 billion at March 31, 2015, compared with $15.3 billion a year ago.

Aflac Japan's investment portfolios include dollar-denominated securities and reverse-dual currency securities (yen-denominated debt securities with dollar coupon payments). Dollar-denominated investment income from these assets accounted for approximately 48% of Aflac Japan’s investment income in the first three months of 2015, compared with 45% a year ago. In years when the yen strengthens in relation to the dollar, translating Aflac Japan's dollar-denominated investment income into yen lowers growth rates for net investment income, total operating revenues, and pretax operating earnings in yen terms. In years when the yen weakens, translating dollar-denominated investment income into yen magnifies growth rates for net investment income, total operating revenues, and pretax operating earnings in yen terms. Excluding foreign currency changes from the prior period, dollar-denominated investment income accounted for approximately 44% of Aflac Japan’s investment income during the first three months of 2015, compared with 43% a year ago.

⁽¹⁾ See the Insurance Operations section of this MD&A for our definition of segment operating earnings.

In the three-month period ended March 31, 2015, the benefit ratio increased compared to the same respective period in the prior year, reflecting a continued increase in the ordinary life benefit ratio, partially offset by reinsurance. The reinsurance agreements that we entered into at the end of third quarter 2013 and the beginning of the fourth quarter 2014 reduced the benefit ratio by approximately 68 basis points for the three-month period ended March 31, 2015. In the first three months of 2015, the operating expense ratio decreased primarily due to an increase in consumption tax refunds and is otherwise stable compared to the previous year. In total, the pretax operating profit margin remained stable in the three-month period ended March 31, 2015, compared with the same period in 2014. For the full year of 2015, we anticipate the pretax operating profit margin to be approximately the same as 2014.

The following table details the contributions to new annualized premium sales by major insurance product for the periods ended March 31.

	Three Months
	2015		2014
Medical	25.6	%	35.4	%
Cancer	41.5		18.6

WAYS	11.7		17.9
Other ordinary life	7.2		9.2
Other	3.7		7.9
Total	100.0	%	100.0	%

The foundation of Aflac Japan's product portfolio has been, and continues to be, our third sector cancer and medical products. Sales of third sector products increased21.3% during the first quarter of 2015, compared with the same period in 2014. We have been focusing more on promotion of our cancer and medical products following the repricing of our first sector life products in April 2013. Sales of cancer insurance continued to be strong following the introduction at the end of the third quarter of 2014 of New Cancer DAYS, which includes an exclusive policy sold through Japan Post. Following strong fourth quarter 2014 sales of New Cancer DAYS, cancer sales in the first quarter of 2015 generated an increase of 118% through all distribution outlets. With continued cost pressure on Japan’s health care system, we expect the need for third sector products will continue to rise in the future, and we remain convinced that the medical and cancer products Aflac Japan provides will continue to be an important part of our product portfolio.

As expected, Aflac Japan’s first sector product sales, which include WAYS and child endowment, were down29.8% in the first quarter of 2015, compared to the same period in the prior year. This contributed to Aflac Japan's overall new annualized premium sales decline of 2.2%. We continue to expect that for 2015, the sale of first sector products will be down compared with 2014, as our focus remains on selling third sector products.

We remain committed to selling through our traditional channels. These channels, consisting of affiliated corporate agencies, independent corporate agencies and individual agencies, accounted for 82.7% of total new annualized premium sales for Aflac Japan in the first quarter of 2015. During the three-month period ended March 31, 2015, we recruited more than 90 new sales agencies. At March 31, 2015, Aflac Japan was represented by approximately 14,100 sales agencies and more than 116,100 licensed sales associates employed by those agencies.

At March 31, 2015, we had agreements to sell our products at 371 banks, or more than 90% of the total number of banks in Japan. Bank channel sales accounted for 17.3% of new annualized premium sales in the first quarter of 2015 for Aflac Japan, compared with 27.8% during the first quarter of 2014.

Aflac Japan and Japan Post Holdings entered into a new agreement in July 2013, further expanding a partnership that was established in 2008 (see Japanese Regulatory Environment). At the end of June 2014, Japan Post Insurance (Kampo) received FSA regulatory approval to enter into an agency contract with Aflac Japan to begin distributing Aflac Japan's cancer insurance products at all of Kampo's 79 directly managed sales offices. Aflac Japan has developed a unique Aflac-branded cancer product for Japan Post and Kampo that was introduced on October 1, 2014. In the fourth quarter of 2014, the number of postal outlets selling our cancer products expanded to approximately 10,000, and Japan Post intends to further expand the number of post offices that offer Aflac's cancer products to 20,000 postal outlets by the end of first quarter 2016. We believe this alliance with Japan Post will further benefit our cancer insurance sales.

We believe that there is still a continued need for our products in Japan. Our sales target and focus in 2015 will continue to be centered around the sale of Aflac Japan's third sector products, including cancer and medical. Although our traditional channels remain key to our success, we have developed partnerships with new channels to help increase our overall sales growth. These channels include Japan Post, and we are making steady progress with our sales through postal outlets. In 2015, we believe that third sector sales will average a 15% increase for the first nine months of the year. However, we believe sales growth of third sector products in the fourth quarter of 2015 could be down sharply relative to the prior year due to difficult comparisons.

Japanese Economy

The Bank of Japan's April 2015 Monthly Report of Recent Economic and Financial Developments stated the following about the Japanese economy. Japan's economy continues to recover moderately, and exports have increased. Public investment has plateaued at a high level while housing investment, which continued to decline following the consumption tax hike, has recently started to bottom out. Private consumption has remained resilient due to steady improvement in employment and income. The report projected that Japan's economy is expected to recover moderately. Exports are expected to increase moderately due to the improving overseas economies. As for domestic demand, public investment is expected to flatten at a high level and subsequently begin to decline moderately. Private consumption is expected to remain resilient due to continued steady improvement in employment and income. Housing investment is projected to gradually regain its resilience as well. For additional information, see the Japanese Economy subsection of MD&A in our annual report to shareholders for the year ended December 31, 2014.

Japanese Regulatory Environment

In 2005, legislation aimed at privatizing Japan's postal system (Japan Post) was enacted into law. The privatization laws split Japan Post into four operating entities that began operations in October 2007. In 2007, one of these entities selected Aflac Japan as its provider of cancer insurance to be sold through its post offices, and, in 2008, we began selling cancer insurance through these post offices. Japan Post has historically been a popular place for consumers to purchase insurance products. Legislation to reform the postal system passed the Diet in April 2012 and resulted in the merger of two of the postal operating entities (the one that delivers the mail and the one that runs the post offices) on October 1, 2012. In July 2013, Aflac Japan entered into a new agreement with Japan Post Holdings to further expand a partnership that was established in 2008 (see Aflac Japan Sales).

On January 16, 2014, Japan’s FSA issued a reporting order pursuant to the Insurance Business Law to all insurance companies, including Aflac Japan, entitled “Regarding the Rectification, etc. of Insurance Agency Employees.” Companies have been ordered to ascertain conditions on the ground regarding sales agents, facilitate the discontinuation of the practice of subcontracting (i.e., the use of non-employee contractors to sell insurance on behalf of insurance agencies), and report to the FSA no later than April 30, 2015. In light of the Company's current mix of distribution channels, the use of non-employee contractors is not a major channel for the Company in Japan.

In June 2013, a revision to the Financial Instruments and Exchange Act established a post-funded Orderly Resolution Regime for financial institutions to prevent a financial crisis in the event of a financial institution’s failure. This regime came into effect in March 2014, but is not expected to have a material impact on the Company's operations in Japan.

Aflac Japan Investments

The level of investment income in yen is affected by available cash flow from operations, the timing of investing the cash flow, yields on new investments, the effect of yen/dollar exchange rates on dollar-denominated investment income, and other factors.

In order to address our challenge of investing in Japan's low-interest-rate environment, Aflac Japan has invested in higher-yielding U.S. dollar-denominated publicly-traded investment grade corporate fixed-maturity securities, and have entered into foreign currency forwards and options to hedge the currency risk on the fair value of the U.S. dollar securities. We started this program as part of our strategic review of portfolio allocation, maintain it as part of our on-going portfolio allocation, and will allocate new money into the program based on multiple factors including market conditions, overall portfolio make-up, investment alternatives, needs of the business, and other factors.

In the first quarter of 2015, in the execution of planned investment portfolio diversification, Aflac Japan increased the allocation of investments to a senior secured bank loan program by approximately $750 million, all of which has been funded, and to a high yield corporate bond program by $500 million, of which approximately $373 million had been funded as of March 31, 2015. See the Analysis of Financial Condition section of this MD&A for further discussion of these investment programs.

The following table presents the results of Aflac Japan’s investment yields for the periods ended March 31.

	Three Months
	2015	(1)	2014	(1)
New money yield	1.13	%	1.99	%
Return on average invested assets, net of investment expenses	2.86		2.76
Portfolio book yield, including dollar-denominated investments, end of period	2.81	%	2.86	%

⁽¹⁾Yields are reported before the cost of foreign currency forwards that hedge foreign exchange risk of U.S. dollar-denominated publicly-

traded corporate bonds.

The new money yield in the table above excludes the reinvestment of sales proceeds that were used to fund the purchase of the senior secured bank loans and high yield corporate bonds. The decline in the Aflac Japan new money yield is primarily due to the modest amount of first quarter 2015 new money being allocated primarily to relatively low-yielding JGBs.

Changes in Aflac U.S. pretax operating earnings and profit margins are primarily affected by morbidity, mortality, expenses, persistency and investment yields. The following table presents a summary of operating results for Aflac U.S.

The benefit ratio remained stable in the three-month period ended March 31, 2015, compared with the same period in 2014. The expense ratio increased primarily due to increased spending associated with changes in the Aflac U.S. sales structure. This fluctuation resulted in an overall decline in the pretax operating profit margin in the three-month period ended March 31, 2015, compared with 2014. For the remainder of 2015, we expect the benefit ratio to be relatively stable and the expense ratio to be higher in the second and third quarter and lower in the fourth quarter compared with 2014.

New annualized premium sales for accident insurance, our leading product category, increased3.6%, short-term disability sales increased8.8%, critical care insurance sales (including cancer insurance) decreased.5%, and hospital indemnity insurance sales decreased14.1% in the first quarter of 2015, compared with the same period in 2014.

In the first quarter of 2015, our traditional U.S. sales forces included more than 8,900 U.S. associates who were actively producing business on a weekly basis. We believe that the average weekly producing sales associates metric allows our sales management to actively monitor progress and needs on a real-time basis. Beyond expanding the size and capabilities of our traditional sales force, we remain encouraged about establishing and developing relationships with insurance brokers that typically handle the larger-case market.

69

The addition of group products has expanded our reach and enabled us to generate more sales opportunities with larger employers, brokers, and our traditional sales agents. We anticipate that the appeal of our group products will continue to enhance our opportunities to connect with larger businesses and their employees. Our portfolio of group and individual products offers businesses the opportunity to give their employees a more valuable and comprehensive selection of benefit options.

Beginning in the third quarter and continuing into the fourth quarter of 2014, Aflac U.S. implemented tactical initiatives centered around providing competitive compensation to our sales hierarchy and positioning us to more effectively and consistently execute on the U.S. sales strategy across all states. These measures are designed to more effectively link sales management's success to Aflac's success. For example, we enhanced compensation through an incentive bonus for the first level of our sales management, district sales coordinators, who are primarily responsible for selling Aflac products and training new sales associates. Additionally, we eliminated the commission-based position of state sales coordinator. To better manage our state operations, we introduced the new position of market director, effective October 1, 2014. Market directors are salaried with the opportunity to earn sales-related bonuses. We believe these changes have enhanced and will continue to enhance performance management and better align compensation with new business results.

With the evolving business market and the coverage standardization that will result from health care reform in the United States, we believe Aflac's voluntary products will become more relevant than ever. Our products provide cash benefits that can be used to help with increasing out-of-pocket medical expenses, help cover household costs, or protect against income and asset loss. Our group products and relationships with insurance brokers that handle the larger-case market are helping us as we expand our reach selling to larger businesses. We are regularly evaluating the marketplace to identify opportunities to bring the most relevant, cost-effective products to our customers. We believe the need for our products remains very strong, and we continue to work on enhancing our distribution capabilities to access employers of all sizes, including initiatives that benefit our field force and the broker community. At the same time, we are seeking opportunities to leverage our brand strength and attractive product portfolio in the evolving health care environment. For 2015, our objective is for Aflac U.S. new annualized premium sales to increase 3% to 7%.

U.S. Economy

Operating in the U.S. economy continues to be challenging. While ongoing uncertainty around health care reform implementation has prompted many businesses and consumers to postpone decisions related to health care coverage, we believe that the need for our products remains strong, and that the United States remains a sizeable and attractive market for our products.

U.S. Regulatory Environment

The Affordable Care Act (ACA) is intended to give Americans of all ages and income levels access to comprehensive major medical health insurance. The major elements of the bill became effective on January 1, 2014. The primary subject of the legislation is major medical insurance; as enacted, the ACA does not materially affect the design of our insurance products. However, indirect consequences of the legislation and regulations, including uncertainty related to implementation, could present challenges and/or opportunities that could potentially have an impact on our sales model, financial condition and results of operations. Our experience with Japan’s national health care environment leads us to believe that the need for supplemental insurance will only increase over the coming years.

The Dodd-Frank Act created, among other things, a Financial Stability Oversight Council (the Council). In April 2012, the Council released a final rule describing the general process it will follow in determining whether to designate a nonbank financial company for supervision by the Board of Governors of the U.S. Federal Reserve System (the Board). The Council may designate by a two-thirds vote whether certain nonbank financial companies, including certain insurance companies and insurance holding companies, could pose a threat to the financial stability of the United States, in which case such nonbank financial companies would become subject to prudential regulation by the Board. On April 3, 2013, the Board published a final rule that establishes the requirements for determining when a nonbank financial company is "predominantly engaged in financial activities" - a prerequisite for designation by the Council. Prudential regulation by the Board includes supervision of capital requirements, leverage limits, liquidity requirements and examinations. The Board may limit such company’s ability to enter into mergers, acquisitions and other business combination transactions, restrict its ability to offer financial products, require it to terminate one or more activities, or impose conditions on the manner in which it conducts activities. The Council designated two insurers in 2013 and an additional insurer in 2014 as a Systemically Important Financial Institution (SIFI) in 2014. On December 18, 2014, President Obama signed the Insurance Capital Standards Clarification Act into law. This legislation will clarify the Board’s authority to apply insurance-based capital standards for insurance companies subject to federal supervision. Although Aflac is a nonbank financial

70

company predominantly engaged in financial activities as defined in the Dodd-Frank Act, we do not believe Aflac will be considered a company that poses a threat to the financial stability of the United States.

Title VII of the Dodd-Frank Act and regulations issued thereunder may have an impact on Aflac's derivative activity, including activity on behalf of Aflac Japan, in particular rules and rule proposals to require central clearing and collateral for certain types of derivatives. The five U.S. banking regulators and the U.S. Commodity Futures Trading Commission (CFTC) recently re-proposed for comment their rules regarding collateral for uncleared swaps. If adopted as proposed, such rules may result in increased collateral requirements for Aflac or impose limits on the types of collateral we are permitted to post.

The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Treasury Department to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance. Traditionally, U.S. insurance companies have been regulated primarily by state insurance departments. In December 2013, the FIO released a report entitled "How To Modernize And Improve The System Of Insurance Regulation In The United States." The report was required by the Dodd-Frank Act, and included 18 recommended areas of near-term reform for the states, including addressing capital adequacy and safety/soundness issues, reform of insurer resolution practices, and reform of marketplace regulation. The report also listed nine recommended areas for direct federal involvement in insurance regulation. Some of the recommendations outlined in the FIO report released in December 2013 have been implemented. Of the nine recommended areas for direct federal involvement in insurance regulation that are applicable to Aflac, President Obama signed the National Association of Registered Agents and Brokers Reform Act into law in January 2015, which simplifies the agent and broker licensing process across state lines. The FIO has also engaged with the supervisory colleges to monitor financial stability and identify regulatory gaps for large national and internationally active insurers.

On December 10, 2013, five U.S. financial regulators adopted a final rule implementing the "Volcker Rule," which was created by Section 619 of the Dodd-Frank Act. The Volcker Rule generally prohibits "banking entities" from engaging in "proprietary trading" and making investments and conducting certain other activities with "private equity funds and hedge funds." The final rule became effective April 1, 2014; however, at the time the agencies released the final Volcker Rule, the Federal Reserve announced an extension of the conformance period for all banking entities until July 21, 2015. In response to industry questions regarding the final Volcker Rule, the five U.S. financial regulators, which included the Office of the Comptroller of the Currency (OCC); the Federal Reserve; the Federal Deposit Insurance Corporation (FDIC); the SEC and the U.S. CFTC, issued a clarifying interim final rule on January 14, 2014 that permits banking entities to retain interests in certain collateralized debt obligations (CDOs) backed by trust preferred securities if the CDO meets certain requirements.

On December 18, 2014, the Federal Reserve announced a second extension to the Volcker Rule conformance period, to give banking entities until July 21, 2016, to conform investments in and relationships with covered funds and foreign funds that were in place prior to December 31, 2013 (legacy covered funds). The Federal Reserve also announced its intention to act in the future to grant banking entities an additional one-year extension of the conformance period until July 21, 2017, to conform ownership interests in and relationships with these legacy covered funds. The Federal Reserve did not act to extend the conformance period for proprietary trading activities.

Nonbank financial companies such as Aflac that are not affiliated with an insured depository institution or otherwise brought within the definition of "banking entity" generally will not be subject to the Volcker Rule's prohibitions. However, the prohibitions of the Volcker Rule could impact financial markets generally, for example, through reduced liquidity in certain markets or the exiting of positions by banking entities as the end of the conformance period approaches.

The process of implementing the Dodd-Frank Act is ongoing and continues to involve additional rulemaking from time to time. At the current time, it is not possible to predict with any degree of certainty what impact, if any, the Dodd-Frank Act will have on our U.S. business, financial condition, or results of operations.

Aflac U.S. Investments

The level of investment income is affected by available cash flow from operations, the timing of investing the cash flow, yields on new investments, and other factors. Aflac U.S. has invested primarily in investment grade corporate bonds.

71

The following table presents the results of Aflac's U.S. investment yields for the periods ended March 31.

	Three Months
	2015		2014
New money yield	3.79	%	4.33	%
Return on average invested assets, net of investment expenses	5.21		5.54
Portfolio book yield, end of period	5.85	%	5.96	%

The decline in the Aflac U.S. new money yield for the three-month period ended March 31, 2015 was primarily due to the decline in the general level of interest rates compared to the prior year period. See Notes 3 and 5 of the Notes to the Consolidated Financial Statements and the Analysis of Financial Condition section of this MD&A for additional information on our investments.

ANALYSIS OF FINANCIAL CONDITION

Our financial condition has remained strong in the functional currencies of our operations. The yen/dollar exchange rate at the end of each period is used to translate yen-denominated balance sheet items to U.S. dollars for reporting purposes.

The following table demonstrates the effect of the change in the yen/dollar exchange rate by comparing select balance sheet items as reported at March 31, 2015, with the amounts that would have been reported had the exchange rate remained unchanged from December 31, 2014.

⁽¹⁾Excludes investment-grade, available-for-sale fixed-maturity securities held by the Parent Company of $498 in 2015 and $437 in

2014.

Because we invest in fixed-maturity securities, our financial instruments are exposed primarily to three types of market risks: currency risk, interest rate risk, and credit risk.

Currency Risk

The functional currency of Aflac Japan's insurance operations is the Japanese yen. All of Aflac Japan's premiums, claims and commissions are received or paid in yen, as are most of its other expenses. Most of Aflac Japan's cash and liabilities are yen-denominated. Aflac Japan's investments consisted primarily of yen-denominated securities of $62.8 billion, at amortized cost, at March 31, 2015. However, Aflac Japan also owns dollar-denominated securities of $13.6 billion, at amortized cost, whose fair value is hedged against currency risk as well as $7.7 billion of securities, at amortized cost, that are not hedged as of March 31, 2015. Due to this investment allocation, yen-denominated investment income accounted for 52% of Aflac Japan's investment income during the three-month period ended March 31, 2015, with the remainder denominated in U.S. dollars. In addition, Aflac Incorporated has yen-denominated debt obligations.

We are exposed to currency risk as an economic event only when yen funds are actually converted into dollars. This occurs when we repatriate yen-denominated funds from Aflac Japan to Aflac U.S. The exchange rates prevailing at the time of repatriation will differ from the exchange rates prevailing at the time the yen profits were earned. A portion of the yen repatriation may be used to service Aflac Incorporated's yen-denominated notes payable with the remainder converted into dollars. In order to hedge foreign exchange risk for a portion of the profit repatriation received in yen from Aflac Japan in February 2015, we had foreign exchange forwards as part of a hedging strategy on 30.0 billion yen. As of March 31, 2015 we had foreign exchange forwards to hedge foreign exchange risk on 157.5 billion yen of future profit repatriation from Aflac Japan.

In addition to profit repatriation, certain investment activities for Aflac Japan expose us to economic currency risk when yen are converted into dollars. As noted above, we invest a portion of our yen cash flows in dollar-denominated assets. This requires that we convert the yen cash flows to U.S. dollars before investing. As previously discussed, for certain of our U.S. dollar-denominated securities, we enter into foreign currency forward and option contracts to hedge the currency risk on the fair value of the securities. The dollar coupon payments received on these investments are not hedged and are subject to foreign exchange fluctuations, which are realized in earnings. Also, Aflac Japan has invested in reverse-dual currency securities (RDCs, or yen-denominated debt securities with dollar coupon payments), which exposes Aflac to changes in foreign exchange rates. The foreign currency effect on the yen-denominated securities is accounted for as a component of unrealized gains or losses on available-for-sale securities in accumulated other comprehensive income, while the foreign currency effect on the dollar coupons is realized in earnings. The RDCs provided a higher yield at the time of purchase than those available on Japanese government or other public corporate bonds, while still adhering to our investment standards at the time of the transaction. The yen/dollar exchange rate would have to strengthen to approximately 40 before the yield on these instruments would equal that of a comparable JGB instrument.

Aside from the activities discussed above, we generally do not convert yen into dollars; however, we do translate financial statement amounts from yen into dollars for financial reporting purposes. Therefore, reported amounts are affected by foreign currency fluctuations. We report unrealized foreign currency translation gains and losses in

73

accumulated other comprehensive income. In periods when the yen weakens against the dollar, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported. The weakening of the yen relative to the dollar will generally adversely affect the value of our yen-denominated investments in dollar terms. We attempt to minimize the exposure of shareholders' equity to foreign currency. We accomplish this by investing a portion of Aflac Japan's investment portfolio in dollar-denominated securities and by the Parent Company's issuance of yen-denominated debt (for additional information, see the discussion under the Hedging Activities subsection of MD&A). As a result, the effect of currency fluctuations on our net assets is reduced.

The following table demonstrates the effect of foreign currency fluctuations by presenting the dollar values of our yen-denominated assets and liabilities, and our consolidated yen-denominated net asset exposure at selected exchange rates.

⁽¹⁾ Actual period-end exchange rate

⁽²⁾ Does not include the U.S. dollar-denominated corporate bonds for which we have entered into foreign currency forwards as

discussed in the Aflac Japan Investment subsection of MD&A

⁽³⁾ Does not include U.S. dollar-denominated bonds that have corresponding cross-currency swaps in consolidated VIEs

We are required to consolidate certain VIEs. Some of the consolidated VIEs in Aflac Japan's portfolio use foreign currency swaps to convert foreign denominated cash flows to yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon exchange rate. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Prior to consolidation, our

74

beneficial interest in these VIEs was a yen-denominated available-for-sale fixed maturity security. Upon consolidation, the original yen-denominated investment was derecognized and the underlying fixed-maturity or perpetual securities and cross-currency swaps were recognized. The combination of a U.S. dollar-denominated investment and cross-currency swap economically creates a yen-denominated investment and has no impact on our net investment hedge position.

Similarly, the combination of the U.S. corporate bonds and the foreign currency forwards and options that we have entered into, as discussed in the Aflac Japan Investment subsection of MD&A, economically creates a yen-denominated investment that qualifies for inclusion as a component of our investment in Aflac Japan for net investment hedge purposes.

For additional information regarding our Aflac Japan net investment hedge, see the Hedging Activities subsection of MD&A.

Interest Rate Risk

Our primary interest rate exposure is to the impact of changes in interest rates on the fair value of our investments in debt and perpetual securities. We estimate that the reduction in the fair value of debt and perpetual securities we own resulting from a 100 basis point increase in market interest rates, based on our portfolios at March 31, 2015, and December 31, 2014, would be as follows:

(In millions)	March 31, 2015				December 31, 2014
Effect on yen-denominated debt and perpetual securities		$	(9,196	)		$	(9,379	)
Effect on dollar-denominated debt and perpetual securities		(3,524		)		(3,427		)
Effect on total debt and perpetual securities		$	(12,720	)		$	(12,806	)

There are various factors that affect the fair value of our investment in debt and perpetual securities. Included in those factors are changes in the prevailing interest rate environment, which directly affect the balance of unrealized gains or losses for a given period in relation to a prior period. Decreases in market yields generally improve the fair value of debt and perpetual securities, while increases in market yields generally have a negative impact on the fair value of our debt and perpetual securities. However, we do not expect to realize a majority of any unrealized gains or losses because we generally have the intent and ability to hold such securities until a recovery of value, which may be maturity. For additional information on unrealized losses on debt and perpetual securities, see Note 3 of the Notes to the Consolidated Financial Statements.

We perform extensive analysis on the duration or our assets and liabilities. Currently, when debt and perpetual securities we own mature, the proceeds may be reinvested at a yield below that of the interest required for the accretion of policy benefit liabilities on policies issued in earlier years. However, adding riders to our older policies has helped offset negative investment spreads on these policies. Overall, adequate profit margins exist in Aflac Japan’s aggregate block of business because of changes in the mix of business and favorable experience from mortality, morbidity and expenses.

Interest rate swaptions are options on interest rate swaps. We have entered into interest rate collars, combinations of two swaption positions, in order to hedge certain dollar-denominated available-for-sale securities that are held in the Aflac Japan segment. We use collars to protect against significant changes in the fair value associated with interest rate changes of our dollar-denominated available-for-sale securities. In order to minimize cost, we set the strike price on each

collar so that the premium paid for the ‘payer leg’ is offset by the premium received for having sold the ‘receiver leg’.

Periodically, depending on general economic conditions, we may enter into other derivative transactions to hedge interest rate risk.

For further information on our interest rate derivatives, see Note 4 of the accompanying Notes to the Consolidated Financial Statements and Note 9 of the Notes to the Consolidated Financial Statements and the Interest Rate Risk subsection of MD&A in our annual report to shareholders for the year ended December 31, 2014.

Credit Risk

A significant portion of our investment portfolio consists of debt securities or perpetual securities that expose us to the credit risk of the underlying issuer. We carefully evaluate this risk on every new investment and closely monitor the credit risk of our existing investment portfolio. We incorporate the needs of our products and liabilities, the overall requirements of the business, and other factors in addition to our underwriting of the credit risk for each investment in the portfolio.

75

Evaluating the underlying risks in our credit portfolio involves a multitude of factors including but not limited to our assessment of the issuers business activities, assets, products, market position, financial condition, and future prospects. We also must incorporate the assessment of the Nationally Recognized Statistical Rating Organizations (NRSROs) in assigning credit ratings to our specific portfolio holdings. We employ a team of experienced credit investment professionals to perform extensive internal assessments of the credit risks for all our portfolio holdings and potential new investments.

The ratings of our securities referenced in the two tables below are based on the ratings designations provided by major NRSROs (Moody's, S&P and Fitch) or, if not rated, are determined based on our internal analysis of such securities. For investment-grade securities where the ratings assigned by the major credit agencies are not equivalent, we use the second lowest rating that is assigned. For a description of the ratings methodology that we use when a security is split-rated, see "Market Risks of Financial Instruments - Below-Investment-Grade and Split-Rated Securities" in the Analysis of Financial Condition section of this MD&A.

The distributions by credit rating of our purchases of debt securities, based on acquisition cost, were as follows:

Composition of Purchases by Credit Rating

	Three Months Ended March 31, 2015			Twelve Months Ended December 31, 2014			Three Months Ended March 31, 2014
AAA		2.7	%		7.6	%		1.3	%
AA		5.0			74.5			72.6
A		11.7			8.0			11.8
BBB		15.3			8.3			13.0
BB or lower		65.3			1.6			1.3
Total		100.0	%		100.0	%		100.0	%

Purchases of securities from period to period are determined based on multiple objectives including appropriate portfolio diversification, the relative value of a potential investment and availability of investment opportunities, liquidity, credit and other risk factors while adhering to our investment policy guidelines. We did not purchase any perpetual securities during the periods presented in the table above. Total purchases comprise new money investments as well as the reinvestment of investment sales proceeds. The relatively higher purchases of AA rated securities in 2014 were primarily due to the purchase of JGBs. The significant increase in purchases of BB or lower rated securities in 2015 was due to increased investment in senior secured bank loans to U.S. and Canadian corporate borrowers, most of which have below-investment-grade ratings, and investment in high yield corporate bonds. The bank loan investment program is managed externally by third party firms specializing in this asset class. This mandate requires a minimum average credit quality of BB-/Ba3, prohibits loans rated below B/B2, and restricts exposure to any individual credit to less than 3% of the program’s assets. The objectives of this program include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates through the acquisition of floating rate assets. The objective of the high yield corporate bond investments is to enhance yield on the Aflac Japan portfolio and further diversify our credit risk. All investments must have a minimum rating of low BB using our above described rating methodology and are managed by our internal credit portfolio management team.

76

The distributions of debt and perpetual securities we own, by credit rating, were as follows:

Composition of Portfolio by Credit Rating

		March 31, 2015						December 31, 2014
	Amortized Cost			Fair       Value			Amortized Cost			Fair       Value
AAA		1.3	%		1.3	%		1.3	%		1.3	%
AA		5.7			5.8			5.7			5.8
A		63.2			63.9			64.1			65.1
BBB		24.9			24.2			25.0			23.9
BB or lower		4.9			4.8			3.9			3.9
Total		100.0	%		100.0	%		100.0	%		100.0	%

As of March 31, 2015, our direct and indirect exposure to securities in our investment portfolio that were guaranteed by third parties was immaterial both individually and in the aggregate.

Subordination Distribution

The majority of our total investments in debt and perpetual securities was senior debt at March 31, 2015, and December 31, 2014. We also maintained investments in subordinated financial instruments that primarily consisted of Lower Tier II, Upper Tier II, and Tier I securities, listed in order of seniority. The Lower Tier II securities are debt instruments with fixed maturities. Our Upper Tier II and Tier I investments consisted of debt instruments with fixed maturities and perpetual securities, which have an economic maturity as opposed to a stated maturity.

The following table shows the subordination distribution of our debt and perpetual securities.

Investment Concentrations

One of our largest investment concentrations as of March 31, 2015, was banks and financial institutions. Approximately 13% and 14% of our total portfolio of debt and perpetual securities, on an amortized cost basis, was in the bank and financial institution sector at March 31, 2015 and December 31, 2014, respectively. Within the countries we approve for investment opportunities, we primarily invest in financial institutions that are strategically crucial to each approved country's economy. The bank and financial institution sector is a highly regulated industry and plays a strategic role in the global economy. Within this sector, our credit risk by geographic region or country of issuer at March 31, 2015, based on amortized cost, was: Europe, excluding the United Kingdom (29%); United States (28%); Australia (8%); Japan (8%); United Kingdom (8%); and other (19%).

Our 15 largest global investment exposures as of March 31, 2015, were as follows:

^* If aggregated, our total exposure under the Berkshire Hathaway family of companies would have placed it among our top 15 exposures. However, we

consider Berkshire Hathaway Energy Company and Burlington Northern Santa Fe, LLC holdings distinct from those of the parent company and believe

it appropriate to report them separately.

78

As previously disclosed, we own long-dated debt instruments in support of our long-dated policyholder obligations. Some of our largest global investment holdings are positions that were purchased many years ago and increased in size due to merger and consolidation activity among the issuing entities. In addition, many of our largest holdings are yen-denominated, therefore strengthening of the yen can increase our position in dollars, and weakening of the yen can decrease our position in dollars. Our global investment guidelines establish concentration limits for our investment portfolios.

Investments in Certain European Countries

Since 2008, many countries in Europe, and specifically Greece, Ireland, Italy, Portugal, and Spain (collectively the "peripheral Eurozone" countries), have been experiencing a debt crisis.  Collective action by multiple parties including the European Central Bank (ECB), International Monetary Fund (IMF), European Council, and individual member states' governments had largely improved market perception of the situation across Europe.  However, in the last few months a change in the political landscape in Greece has increased the probability they may be unable to repay or refinance upcoming debt needs, creating a situation many feel could lead to their ultimate exit from the European Monetary Union. Despite the situation in Greece, most European sovereigns have seen their credit worthiness stabilize as the risk of the entire monetary union dissolving has been greatly reduced.  While recent economic indicators suggest improvement from the depths of the crisis, overall economic activity remains subdued throughout the region. As many Eurozone economies struggle with sustainable economic growth following the region’s recent sovereign debt and banking crisis, the ECB has launched a quantitative easing (QE) stimulus program. Throughout the crisis we have taken steps to improve the risk profile of our portfolio by selling certain holdings throughout Europe, including the periphery countries.

The primary factor considered when determining the domicile of investment exposure is the legal domicile of the issuer. However, other factors such as the location of the parent guarantor, the location of the company's headquarters or major business operations (including location of major assets), location of primary market (including location of revenue generation) and specific country risk publicly recognized by rating agencies can influence the assignment of the country (or geographic) risk location. When the issuer is a special financing vehicle or a branch or subsidiary of a global company, then we consider any guarantees and/or legal, regulatory and corporate relationships of the issuer relative to its ultimate parent in determining the proper assignment of country risk.

European sovereign debt crisis - monitoring and mitigating exposure

During most of 2011, we saw the European sovereign crisis persist and escalate. During the crisis in 2011 and 2012, we undertook a derisking program to reduce significant concentrations within our investment portfolio, most notably perpetual securities issued by financial institutions and instruments issued by other peripheral Eurozone issuers. We remain diligent in monitoring our portfolio and continually evaluate opportunities to manage risk within our portfolio.

Our internal team of experienced credit professionals has continued to monitor the impact of the crisis on our individual investment holdings' overall credit quality. Our analysis includes factors beyond a baseline assessment of a company's assets, operations, financial statements, and credit metrics that may provide support for the instruments we own. Specifically, for our investments in European banks and financial institutions, we monitor the importance of the issuer to its local financial system, the likelihood of government support, and our investment's position in the capital structure of the issuer. For our investments in European utilities, we monitor the role of the issuer in its local economy as a provider of necessary infrastructure, and we monitor the value of the underlying assets owned by the issuer. For our investment in European corporates, industrials, and other commercial entities, we monitor the general credit quality of the issuer, the geographical mix of the issuer's customers (i.e. domestic vs. foreign), the geographical breakdown of the issuer's assets (i.e. domestic versus foreign), the value of the underlying assets owned by the issuer, capitalization of the issuer, and overall profitability and cash generation ability of the issuer. We monitor NRSRO actions and the likely actions for our investment exposures, as well as overall market conditions. By performing these analyses, we make a determination on the probability of timely payment of principal and interest of the issuers of our investments.

Some of our peripheral Eurozone fixed-maturity investments contain covenants that we believe mitigate our risk to the issuer. These covenants could include put options that allow us to return our holdings to the issuer at a predetermined price, usually par, should the issuer be downgraded to below investment grade by a rating agency, plus restrictions on the ability to incur additional debt, sell assets, or provide collateral for indebtedness. As of March 31, 2015, all of the issuers of our holdings from peripheral Eurozone countries were current on their obligations to us, and we believe they have the ability to meet their obligations to us.

Apart from our direct investments in peripheral Eurozone sovereign debt totaling $263 million, our other exposures as of March 31, 2015 to the European sovereign debt crisis were investments in peripheral Eurozone banks and financial institutions of $493 million, peripheral Eurozone non-banks (excluding sovereigns) of $2.2 billion, core Eurozone¹ banks and financial institutions of $1.9 billion, core Eurozone non-banks (excluding sovereigns) of $4.2 billion, core Eurozone sovereigns of $487 million, and non-Eurozone² holdings throughout the balance of Europe of $5.6 billion, all at amortized cost. Other investment risks stemming from the European sovereign debt crisis are not possible to measure and include the impact of slower economic activity throughout Europe and its impact on global economic growth and market disruption including illiquidity and impaired valuations due to heightened concerns and lack of investor confidence.

Although the situation had largely stabilized across Europe, the crisis in Greece demonstrates certain risks remain as the area continues working to improve their economic footing.  We continue to monitor the situation closely including the heightened interrelationship between political, monetary, fiscal, and economic forces; the pace of underlying structural reforms; the possibility of continued contagion to additional sovereigns and other entities; further stress on the banking systems throughout the region; and the impact on the underlying economic fundamentals throughout the Eurozone.

Securities by Type of Issuance

We have investments in both publicly and privately issued securities. Our ability to sell either type of security is a function of overall market liquidity which is impacted by, among other things, the amount of outstanding securities of a particular issuer or issuance, trading history of the issue or issuer, overall market conditions, and idiosyncratic events affecting the specific issue or issuer.

The following table details investment securities by type of issuance.

⁽¹⁾ Principal payments in yen and interest payments in dollars

Aflac Japan has invested in privately issued securities to better match liability characteristics and secure higher yields than those available on Japanese government or other public corporate bonds. All of the privately issued securities we have purchased were rated investment grade at the time of purchase. Aflac Japan’s investments in yen-denominated privately issued securities consist primarily of non-Japanese issuers and have longer maturities, thereby allowing us to improve our asset/liability matching and our overall investment returns. These securities were generally either privately negotiated arrangements or were issued under medium-term note programs and have standard documentation commensurate with credit ratings of the issuer, except when internal credit analysis indicates that additional protective and/or event-risk covenants were required. Many of these investments have protective covenants appropriate to the specific investment. These may include a prohibition of certain activities by the borrower, maintenance of certain financial measures, and specific conditions impacting the payment of our notes.

Below-Investment-Grade and Split-Rated Securities

We use specific criteria to judge the credit quality of both existing and prospective investments. The ratings referenced in the tables below are based on the ratings designations provided by the major credit rating agencies(Moody's, S&P, and Fitch) or, if not rated, are determined based on our internal credit analysis of such securities. When the ratings issued by the rating agencies differ, we utilize the second lowest rating, regardless of how many of the three rating agencies actually rated the instrument. Split-rated securities are those where the ratings are not equivalent and one or more of the ratings is investment grade and one or more is below investment grade. For these split-rated securities, if there are only two ratings assigned by the credit rating agencies, we take the lower below-investment-grade rating. If there are three ratings assigned, and two of the three are below investment grade, we consider it a below-investment grade security. If there are three ratings and two are investment grade, we consider it an investment grade security unless our evaluation and assessment shows a below-investment-grade rating is warranted despite two of the three rating agencies rating it investment grade.

Our portfolio of below-investment-grade securities includes debt securities purchased while the issuer was rated investment grade plus other loans and bonds purchased as part of an allocation to that segment of the market. The following is our below-investment-grade exposure in accordance with the above described rating methodology.

We invest in senior secured bank loans to U.S. and Canadian corporate borrowers, most of which have below-investment-grade ratings. The program is managed externally by third party firms specializing in this asset class. This mandate requires a minimum average credit quality of BB-/Ba3, prohibits loans rated below B/B2, and prohibits exposure to any individual credit greater than 3% of the program’s assets. The objectives of this program include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates through the acquisition of floating rate assets. Our investments in this program totaled $1.2 billion at March 31, 2015, compared with $501 million at December 31, 2014, on an amortized cost basis.

In the first quarter of 2015, as part of our normal portfolio management and asset allocation process, we increased our allocation within the Aflac Japan portfolio to high yield corporate bonds by $500 million. As of March 31, 2015, $373 million had been funded with below-investment-grade and investment grade securities. The objective of this allocation is to enhance our yield on this portion of the portfolio and further diversify our credit risk. All investments must have a minimum rating of low BB using our above described rating methodology and are managed by our internal credit portfolio management team.

Excluding the senior secured bank loans and certain high yield corporate bonds discussed above that were rated below investment grade when initially purchased, below-investment-grade debt and perpetual securities represented 3.4% of total debt and perpetual securities at both March 31, 2015 and December 31, 2014, on an amortized cost basis. Debt and perpetual securities classified as below investment grade at March 31, 2015 and December 31, 2014 were generally reported as available for sale and carried at fair value.

Split-rated securities, excluding the senior secured bank loan investments and high yield corporate bonds discussed above, totaled $2.2 billion and represented 2.3% of total debt and perpetual securities, at amortized cost, at both March 31, 2015 and December 31, 2014.

For the foreign currency and credit default swaps associated with our VIE investments for which we are the primary beneficiary, we bear the risk of foreign exchange and/or credit loss due to counterparty default even though we are not a direct counterparty to those contracts. We are a direct counterparty to the foreign currency swaps that we have on certain of our senior notes and subordinated debentures; foreign currency forwards; foreign currency options; and interest rate swaptions, therefore we are exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for our VIE and senior note and subordinated debenture swaps, foreign currency forwards and options, and swaptions is mitigated by collateral posting requirements the counterparty must meet. If collateral posting agreements are not in place, the counterparty risk associated with foreign currency forwards and foreign currency options is the risk that at expiry of the contract, the counterparty is unable to deliver the agreed upon amount of yen at the agreed upon price or delivery date, thus exposing the company to additional unhedged exposure to U.S. dollars in the Aflac Japan investment portfolio. See Note 4 of the Notes to the Consolidated Financial Statements for more information.

The declines in the fair values noted above were a result of changes in interest rates, movement in the yen/dollar exchange rate, and/or changes in credit spreads driven by the issuer’s underlying credit quality. As we believe these issuers have the ability to continue making timely payments of principal and interest, we view these changes in fair value to be temporary and do not believe it is necessary to impair the carrying value of these securities. See the Unrealized Investment Gains and Losses section in Note 3 of the Notes to the Consolidated Financial Statements for further discussions of unrealized losses related to financial institutions, including perpetual securities, and other corporate investments.

Investment Valuation and Cash

We estimate the fair values of our securities on a monthly basis. We monitor the estimated fair values obtained from our custodian, pricing vendors and brokers for consistency from month to month, while considering current market conditions. We also periodically discuss with our custodian and pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, we will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, we may compare the inputs to relevant market indices and other performance measurements. The output of this analysis is presented to the Company's Valuations and Classifications Subcommittee, or VCS. Based on the analysis provided to the VCS, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. We have performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value.

Cash and cash equivalents totaled $4.4 billion, or 4.0% of total investments and cash, as of March 31, 2015, compared with $4.7 billion, or 4.3%, at December 31, 2014. For a discussion of the factors affecting our cash balance, see the Operating Activities, Investing Activities and Financing Activities subsections of this MD&A.

Notes Payable

Notes payable totaled $6.3 billion at March 31, 2015, compared with $5.3 billion at December 31, 2014. In March 2015, the Parent Company issued two series of senior notes totaling $1.0 billion through a U.S. public debt offering. The first series, which totaled $550 million, bears interest at a fixed rate of 2.40% per annum, payable semi-annually, and has a five-year maturity. The second series, which totaled $450 million, bears interest at a fixed rate of 3.25% per annum, payable semi-annually, and has a ten-year maturity. We have entered into cross-currency swaps that convert the dollar-denominated principal and interest on the senior notes into yen-denominated obligations which results in lower nominal net interest rates on the debt. By entering into these cross-currency swaps, we economically converted our $550 million liability into a 67.0 billion yen liability and reduced the interest rate on this debt from 2.40% in dollars to .24% in yen, and we economically converted our $450 million liability into a 55.0 billion yen liability and reduced the interest rate on this debt from 3.25% in dollars to .82% in yen.

In April 2015, the Parent Company used the proceeds from the March 2015 issuance of its fixed-rate senior notes to redeem $850 million of our 8.50% fixed-rate senior notes due May 2019 and to pay a portion of the corresponding $230 million make-whole premium due to the investors of these notes.

See Note 7 of the accompanying Notes to the Consolidated Financial Statements for additional information on our notes payable.

Benefit Plans

Aflac Japan and Aflac U.S. have various benefit plans. For additional information on our Japanese and U.S. plans, see Note 10 of the accompanying Notes to the Consolidated Financial Statements and Note 14 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014.

Policyholder Protection Corporation

The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. On December 27, 2011, Japan's FSA announced the plans to enhance the stability of the LIPPC by extending the government's fiscal support of the LIPPC through March 2017. Accordingly, the FSA submitted legislation to the Diet on January 27, 2012 to extend the government's fiscal support framework, andthe legislation was approved on March 30, 2012. Effective April 2014, the annual LIPPC contribution amount for the total life industry was lowered from 40 billion yen to 33 billion yen.

Hedging Activities

Net Investment Hedge

Our primary exposure to be hedged is our investment in Aflac Japan, which is affected by changes in the yen/dollar exchange rate. To mitigate this exposure, we have taken the following courses of action. First, Aflac Japan maintains certain unhedged dollar-denominated securities, which serve as an economic currency hedge of a portion of our investment in Aflac Japan. Second, we have designated the majority of the Parent Company’s yen-denominated liabilities (Samurai and Uridashi notes and yen-denominated loans) as non-derivative hedging instruments and certain foreign currency forwards and options as derivative hedges of our net investment in Aflac Japan. We make our net investment hedge designation at the beginning of each quarter. If the total of the designated Parent Company non-derivative and derivatives notional is equal to or less than our net investment in Aflac Japan, the hedge is deemed to be effective, and the exchange effect on the yen-denominated liabilities and the change in estimated fair value of the derivatives are reported in the unrealized foreign currency component of other comprehensive income. We estimate that if the designated net investment hedge positions exceeded our net investment in Aflac Japan by 10 billion yen, we would report a foreign exchange gain/loss of approximately $1 million for every 1% yen weakening/strengthening in the end-of-period yen/dollar exchange rate. Our net investment hedge was effective during the three-month periods ended March 31, 2015 and 2014.

The yen net asset figure calculated for hedging purposes differs from the yen-denominated net asset position as discussed in the Currency Risk subsection of MD&A. As disclosed in that subsection, the consolidation of the underlying assets in certain VIEs requires that we derecognize our yen-denominated investment in the VIE and recognize the underlying fixed-maturity or perpetual securities and cross-currency swaps. While these U.S. dollar investments will create foreign currency fluctuations, the combination of the U.S. dollar-denominated investment and the cross-currency swap economically creates a yen-denominated investment that qualifies for inclusion as a component of our investment in Aflac Japan. Similarly, the combination of the U.S. corporate bonds and the foreign currency forwards that we have entered

87

into, as discussed in the Aflac Japan Investment subsection of MD&A, economically creates a yen-denominated investment that qualifies for inclusion as a component of our investment in Aflac Japan.

The dollar values of our yen-denominated net assets, including economic yen-denominated investments for net investment hedging purposes as discussed above, are summarized as follows (translated at end-of-period exchange rates):

Aflac Japan net assets		$	15,162			$	14,665
Aflac Japan unhedged dollar-denominated net assets		(8,467		)		(8,672		)
Consolidated yen-denominated net assets (liabilities)		$	6,695			$	5,993

For the hedge of our net investment in Aflac Japan, we have designated certain of the Parent Company's yen-denominated liabilities, certain unhedged U.S. dollar investments and foreign currency forwards and options as a hedge of our net investment in Aflac Japan. Our consolidated yen-denominated net assets position was partially hedged at $1.6 billion as of March 31, 2015 and December 31, 2014, respectively.

Cash Flow Hedges

We had freestanding derivative instruments related to our consolidated VIE investments that are reported in the consolidated balance sheet at fair value within other assets and other liabilities. As of March 31, 2015, two of the freestanding swaps that are used within VIEs to hedge the risk arising from changes in foreign currency exchange rates qualified for hedge accounting.

Fair Value Hedges

We have entered into foreign currency forwards and options to mitigate the foreign exchange risk associated with new investments in U.S. dollar-denominated fixed-maturities that support yen-denominated liabilities within our Aflac Japan segment.

We have entered into interest rate swaptions to mitigate the interest rate risk associated with our U.S. dollar-denominated fixed-maturities that support yen-denominated liabilities within our Aflac Japan segment.

See Note 4 of the Notes to the Consolidated Financial Statements for additional information on our hedging activities.

Off-Balance Sheet Arrangements

As of March 31, 2015, we had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 15 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014, for information on material unconditional purchase obligations that are not recorded on our balance sheet.

CAPITAL RESOURCES AND LIQUIDITY

Aflac provides the primary sources of liquidity to the Parent Company through dividends and management fees. The following table presents the amounts provided for the three-month periods ending March 31.

Liquidity Provided by Aflac to Parent Company

(In millions)	2015		2014
Dividends declared or paid by Aflac	$	369	$	269
Management fees paid by Aflac	93		75

The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock and interest on its outstanding indebtedness. The Parent Company's sources and uses of cash are reasonably predictable and are not expected to change materially in the future. For additional information, see the Financing Activities subsection of this MD&A.

88

The Parent Company also accesses debt security markets to provide additional sources of capital. We filed a shelf registration statement with the SEC in May 2012 that allows us to issue an indefinite amount of senior and subordinated debt, in one or more series, from time to time until May 2015. In March 2014, we filed a shelf registration statement with Japanese regulatory authorities that allows us to issue up to 100 billion yen of yen-denominated Samurai notes in Japan through March 2016. If issued, these yen-denominated Samurai notes would not be available to U.S. persons. We believe outside sources for additional debt and equity capital, if needed, will continue to be available. For additional information, see Note 7 of the Notes to the Consolidated Financial Statements.

The principal sources of cash for our insurance operations are premiums and investment income. The primary uses of cash by our insurance operations are investments, policy claims, commissions, operating expenses, income taxes and payments to the Parent Company for management fees and dividends. Both the sources and uses of cash are reasonably predictable.

When making an investment decision, our first consideration is based on product needs. Our investment objectives provide for liquidity through the purchase of investment-grade debt securities. These objectives also take into account duration matching, and because of the long-term nature of our business, we have adequate time to react to changing cash flow needs.

As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments. We expect our future cash flows from premiums and our investment portfolio to be sufficient to meet our cash needs for benefits and expenses.

In February 2015, the Parent Company and Aflac jointly entered into an uncommitted bank line of credit with a third party that provides for borrowings in the amount of $50 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expenses or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of March 31, 2015, we did not have any borrowings outstanding under our $50 million credit agreement.

The Parent Company and Aflac have an uncommitted bilateral line of credit that provides for borrowings in the amount of $100 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expenses or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of March 31, 2015, we did not have any borrowings outstanding under our $100 million credit agreement. Borrowings under the financing agreement will mature no later than three months after the last drawdown date of October 15, 2015.

The Parent Company and Aflac have a senior unsecured revolving credit facility agreement with a syndicate of financial institutions in the amount of 50 billion yen. This credit agreement provides for borrowings in Japanese yen or the equivalent of Japanese yen in U.S. dollars on a revolving basis. Borrowings will bear interest at LIBOR plus the applicable margin of 1.125%. In addition, the Parent Company and Aflac are required to pay a facility fee of .125% on the commitments. Borrowings under the credit agreement may be used for general corporate purposes, including a capital contingency plan for our Japanese operations. Borrowings under the financing agreement mature at the termination date of the credit agreement. The agreement requires compliance with certain financial covenants on a quarterly basis. This credit agreement will expire on the earlier of March 29, 2018, or the date of termination of the commitments upon an event of default as defined in the agreement. As of March 31, 2015, we did not have any borrowings outstanding under our 50 billion yen revolving credit agreement.

Our financial statements convey our financing arrangements during the periods presented. We have not engaged in material intra-period short-term financings during the periods presented that are not otherwise reported in our balance sheet. We were in compliance with all of the covenants of our notes payable and lines of credit at March 31, 2015. We have not entered into transactions involving the transfer of financial assets with an obligation to repurchase financial assets that have been accounted for as a sale under applicable accounting standards, including securities lending transactions. See Note 3 and 4 of the Notes to the Consolidated Financial Statements and Note 1 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014, for more information on our securities lending and derivatives activities. With the exception of disclosed activities in those referenced footnotes, we do not have a known trend, demand, commitment, event or uncertainty that would reasonably result in our liquidity increasing or decreasing by a material amount. Our cash and cash equivalents include unrestricted cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased, all of which has minimal market, settlement or other risk exposure.

Consolidated Cash Flows

We translate cash flows for Aflac Japan’s yen-denominated items into U.S. dollars using weighted-average exchange rates. In periods when the yen weakens, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported.

The following table summarizes consolidated cash flows by activity for the three-month periods ended March 31.

(In millions)	2015			2014
Operating activities	$	1,460		$	1,615
Investing activities	(2,078		)	(2,123		)
Financing activities	322			(32		)
Exchange effect on cash and cash equivalents	1			(9		)
Net change in cash and cash equivalents	$	(295	)	$	(549	)

Operating Activities

The following table summarizes operating cash flows by source for the three-month periods ended March 31.

(In millions)	2015		2014
Aflac Japan	$	982	$	1,340
Aflac U.S. and other operations	478		275
Total	$	1,460	$	1,615

Investing Activities

Operating cash flow is primarily used to purchase debt securities to meet future policy obligations. The following table summarizes investing cash flows by source for the three-month periods ended March 31.

(In millions)	2015			2014
Aflac Japan	$	(1,925	)	$	(2,033	)

Total	$	(2,078	)	$	(2,123	)

Prudent portfolio management dictates that we attempt to match the duration of our assets with the duration of our liabilities. Currently, when our fixed-maturity securities and perpetual securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of our business and our strong cash flows provide us with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. When needed or when market opportunities arise, we dispose of selected fixed-maturity and perpetual securities that are available for sale to improve the duration matching of our assets and liabilities, improve future investment yields, and/or re-balance our portfolio. As a result, dispositions before maturity can vary significantly from year to year. Dispositions before maturity were approximately 1% of the year-to-date average investment portfolio of fixed maturities and perpetual securities available for sale during the three-month periods ended March 31, 2015 and 2014.

Financing Activities

Consolidated cash provided by financing activities was $322 million in the first three months of 2015, compared with consolidated cash used by financing activities of $32 million for the same period of 2014.

In March 2015, the Parent Company issued two series of senior notes totaling $1.0 billion through a U.S. public debt offering. The first series, which totaled $550 million, bears interest at a fixed rate of 2.40% per annum, payable semi-annually, and has a five-year maturity. The second series, which totaled $450 million, bears interest at a fixed rate of 3.25% per annum, payable semi-annually, and has a ten-year maturity. We have entered into cross-currency swaps that convert the dollar-denominated principal and interest on the senior notes into yen-denominated obligations which results in lower nominal net interest rates on the debt. By entering into these cross-currency swaps, we economically converted our $550 million liability into a 67.0 billion yen liability and reduced the interest rate on this debt from 2.40% in dollars to .24% in yen, and we economically converted our $450 million liability into a 55.0 billion yen liability and reduced the interest rate on this debt from 3.25% in dollars to .82% in yen.

90

In April 2015, the Parent Company used $1.0 billion of fixed-rate senior notes that were issued in March 2015 to redeem $850 million of our 8.50% fixed-rate senior notes due May 2019 and to pay a portion of the corresponding $230 million make-whole premium due to the investors of these notes. We consider the make-whole payment a non-recurring transaction and therefore will exclude this charge from operating earnings in the second quarter of 2015.

Cash returned to shareholders through dividends and treasury stock purchases was $775 million during the three-month period ended March 31, 2015, compared with $584 million during the three-month period ended March 31, 2014.

We were in compliance with all of the covenants of our notes payable and lines of credit at March 31, 2015.

The following tables present a summary of treasury stock activity during the three-month periods ended March 31.

Treasury Stock Purchased

(In millions of dollars and thousands of shares)	2015		2014
Treasury stock purchases	$	610	$	421
Number of shares purchased:
Open market	9,827		6,535
Other	162		110
Total shares purchased	9,989		6,645

Stock issued from treasury:
Cash financing	$	13	$	16
Noncash financing	18		18
Total stock issued from treasury	$	31	$	34
Number of shares issued	593		686

During the first three months of 2015, we repurchased 9.8 million shares of our common stock for $600 million as part of our share repurchase program. As of March 31, 2015, a remaining balance of 19.7 million shares of our common stock was available for purchase under share repurchase authorizations by our board of directors. We currently plan to repurchase $1.3 billion of our common stock in 2015.

Cash dividends paid to shareholders were $.39 per share in the first quarter of 2015, compared with $.37 per share in the first quarter of 2014. The following table presents the dividend activity for the three-month periods ended March 31.

(In millions)	2015		2014
Dividends paid in cash	$	165	$	163
Dividends through issuance of treasury shares	6		7
Total dividends to shareholders	$	171	$	170

In April 2015, the board of directors declared the second quarter cash dividend of $.39 per share, an increase of 5.4% compared with the same period in 2014. The dividend is payable on June 1, 2015, to shareholders of record at the close of business on May 20, 2015.

Regulatory Restrictions

Aflac is domiciled in Nebraska and is subject to its regulations. A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from GAAP and are intended to emphasize policyholder protection and company solvency. The continued long-term growth of our business may require increases in the statutory capital and surplus of our insurance operations. Aflac’s insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings or equity contributions by the Parent

91

Company from funds generated through debt or equity offerings. The NAIC’s risk-based capital (RBC) formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations. As of March 31, 2015, Aflac’s RBC ratio remains high and reflects a strong capital and surplus position. The maximum amount of dividends that can be paid to the Parent Company by Aflac without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2015 in excess of $2.4 billion would require such approval.

In addition to limitations and restrictions imposed by U.S. insurance regulators, Japan’s FSA may not allow profit repatriations from Aflac Japan if the transfers would cause Aflac Japan to lack sufficient financial strength for the protection of policyholders. The FSA maintains its own solvency standard which is quantified through the solvency margin ratio (SMR). Aflac Japan's SMR is sensitive to interest rate and foreign exchange rate changes, therefore we continue to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in interest rates, we have a senior unsecured revolving credit facility in the amount of 50 billion yen as a capital contingency plan. We have already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, we employ policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. For U.S. GAAP, PRM investments are categorized as available-for-sale. We also have interest rate swaptions to mitigate increases in U.S. interest rates and the related impact to the available-for-sale investment portfolio in Japan. In the first quarter of 2015, Aflac Japan entered into an additional quota share arrangement to cede a portion of hospital benefits of one of our closed products. Under this coinsurance indemnity type of reinsurance, Aflac Japan released approximately 130 billion yen of FSA reserves. (See Notes 3, 4, and 8 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014 for additional information on our investment strategies and hedging activities, respectively.) As of March 31, 2015, Aflac Japan's SMR remains high and reflects a strong capital position.

Payments are made from Aflac Japan to the Parent Company for management fees and to Aflac U.S. for allocated expenses and remittances of earnings. The following table details Aflac Japan remittances for the three-month periods ended March 31.

Aflac Japan Remittances

(In millions of dollars and billions of yen)	2015		2014
Aflac Japan management fees paid to Parent Company	$	12	$	12
Expenses allocated to Aflac Japan	28		26
Aflac Japan profit remittances to Aflac U.S. in dollars	250		0
Aflac Japan profit remittances to Aflac U.S. in yen	30.0		0.0

We entered into foreign exchange forwards as part of an economic hedge on foreign exchange risk on 30 billion yen of profit repatriation received in February 2015, resulting in $7 million of additional funds received when the yen was exchanged into dollars. We currently plan to repatriate a total of 200 billion yen from Aflac Japan for the full year 2015.

For additional information on regulatory restrictions on dividends, profit repatriations and other transfers, see Note 13 of the Notes to the Consolidated Financial Statements and the Regulatory Restrictions subsection of MD&A, both in our annual report to shareholders for the year ended December 31, 2014.

Disclosure Controls and Procedures

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this quarterly report (the “Evaluation Date”). Based on such evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective.

BUSINESS SEGMENT INFORMATION

Segment Reporting [Abstract]

BUSINESS SEGMENT INFORMATION

BUSINESS SEGMENT INFORMATION

The Company consists of two reportable insurance business segments: Aflac Japan and Aflac U.S., both of which sell supplemental health and life insurance. Operating business segments that are not individually reportable and business activities not included in Aflac Japan or Aflac U.S. are included in the "Other business segments" category.

We do not allocate corporate overhead expenses to business segments. We evaluate and manage our business segments using a financial performance measure called pretax operating earnings. Our definition of operating earnings includes interest cash flows associated with notes payable and excludes the following items from net earnings on an after-tax basis: realized investment gains/losses (securities transactions, impairments, and the impact of derivative and hedging activities), nonrecurring items and other non-operating income (loss). We then exclude income taxes related to operations to arrive at pretax operating earnings. Information regarding operations by segment follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business 

Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States and Japan. The Company's insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac), which operates in the United States (Aflac U.S.) and as a branch in Japan (Aflac Japan). American Family Life Assurance Company of New York (Aflac New York) is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. Additionally, Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. Our insurance operations in the United States and our branch in Japan service the two markets for our insurance business. Aflac Japan's revenues, including realized gains and losses on its investment portfolio, accounted for 70% and 75% of the Company's total revenues in the three-month periods ended March 31, 2015, and 2014, respectively. The percentage of the Company's total assets attributable to Aflac Japan was 82% at March 31, 2015 and December 31, 2014.

Basis of Presentation

We prepare our financial statements in accordance with U.S. generally accepted accounting principles (GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to GAAP issued by the FASB are derived from the FASB Accounting Standards Codification^TM (ASC). The preparation of financial statements in conformity with GAAP requires us to make estimates when recording transactions resulting from business operations based on currently available information. The most significant items on our balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments, deferred policy acquisition costs, liabilities for future policy benefits and unpaid policy claims, and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, mortality, morbidity, commission and other acquisition expenses, and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates will be revised and reflected in operating results. Although some variability is inherent in these estimates, we believe the amounts provided are adequate.

The unaudited consolidated financial statements include the accounts of the Parent Company, its subsidiaries and those entities required to be consolidated under applicable accounting standards. All material intercompany accounts and transactions have been eliminated.

In the opinion of management, the accompanying unaudited consolidated financial statements of the Company contain all adjustments, consisting of normal recurring accruals, which are necessary to fairly present the consolidated balance sheets as of March 31, 2015 and December 31, 2014, the consolidated statements of earnings, comprehensive income (loss), shareholder's equity and cash flows for the three-month periods ended March 31, 2015 and 2014. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, these financial statements should be read in conjunction with the financial statements and notes thereto included in our annual report to shareholders for the year ended December 31, 2014.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Income Statement - Extraordinary and Unusual Items - Simplifying income statement presentation by eliminating the concept of extraordinary items: In January 2015, the FASB issued updated guidance that eliminates from GAAP the concept of extraordinary items. Although the amendments will eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The amendments in this updated guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We adopted this guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations.

Transfers and Servicing, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures: In June 2014, the FASB issued updated guidance for repurchase agreement and security lending transactions to change the accounting for repurchase-to-maturity transactions and linked repurchase financings to be accounted for as secured borrowings, consistent with the accounting for other repurchase agreements. The amendments also require new disclosures to increase transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. We adopted accounting changes for the new guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations. However, the disclosures in the new guidance are required and will be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015.

Accounting Pronouncements Pending Adoption

Interest - Imputation of Interest - Simplifying the presentation of debt issuance costs: In April 2015, FASB issued updated guidance to simplify presentation of debt issuance costs. The updated guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. The amendment is effective for annual periods and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Consolidation - Amendments to the consolidation analysis: In February 2015, the FASB issued updated guidance that affect evaluation of whether limited partnerships and similar legal entities (limited liability corporations and securitization structures, etc.) are variable interest entities (VIEs), evaluation of whether fees paid to a decision maker or a service provider are a variable interest, and evaluation of the effect of fee arrangements and the effect of related parties on the determination of the primary beneficiary under the VIE model for consolidation. The updated guidance eliminates the presumption that a general partner should consolidate a limited partnership. Limited partnership and similar legal entities that provide partners with either substantive kick-out rights or substantive participating rights (representing the partners’ controlling financial interest in the entity) over the general partner will now be evaluated under the voting interest model rather than the VIE model for consolidation. In regard to the fees paid to a decision maker or a service provider, the updated guidance eliminates three of the six criteria that an entity’s decision makers or service providers must meet for them to conclude that the fees do not represent a variable interest in that entity and, thus, should be excluded from the assessment for determining the primary beneficiary. Finally, in situations where no single party has a controlling financial interest in a VIE, the related party relationships under common control should be considered in their entirety in determining whether that common control group has a controlling financial interest in the VIE. However, if substantially all of the activities of the VIE are conducted on behalf of a single variable interest holder (excluding the decision maker) in a related party group that has the characteristics of a primary beneficiary, that single variable interest holder must consolidate the VIE as the primary beneficiary. The amendments in the updated guidance are effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017. Early application is permitted, including adoption in an interim period. We are evaluating whether the adoption of this guidance will have an impact on our financial position, results of operations or disclosures.

Derivatives and Hedging - Determining whether the host contract in a hybrid financial instrument issued in the form of a share is more akin to debt or equity: In November 2014, the FASB issued guidance to clarify how to evaluate the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. The guidance also clarifies that an entity should assess the substance of the relevant terms and features when considering how to weight those terms and features. The guidance is effective for annual periods and interim periods beginning after December 15, 2015. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Presentation of Financial Statements - Going Concern - Disclosure of uncertainties about an entity’s ability to continue as a going concern: In August 2014, the FASB issued this amendment that provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendment is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Compensation - Stock Compensation - Accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period: In June 2014, the FASB issued this amendment that provides guidance on certain share-based payment awards that require a specific performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Revenue from contracts with customers: In May 2014, the FASB issued updated guidance that affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Recent accounting guidance not discussed above is not applicable, did not have, or is not expected to have a material impact to our business. 

For additional information on new accounting pronouncements and recent accounting guidance and their impact, if any, on our financial position or results of operations, see Note 1 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]

BENEFIT PLANS

BENEFIT PLANS

We have funded defined benefit plans in Japan and the United States, which cover substantially all of our full-time employees. Additionally, we maintain non-qualified, unfunded supplemental retirement plans that provide defined pension benefits in excess of limits imposed by federal tax law for certain Japanese, U.S. and former employees. Effective October 1, 2013, the U.S. tax-qualified defined benefit plan was frozen to new employees hired on or after October 1, 2013 and to employees rehired on or after October 1, 2013. U.S. employees who are not participants in the defined benefit plan receive a nonelective 401(k) employer contribution. Additionally, effective January 1, 2015, the U.S. non-qualified supplemental retirement plan was frozen to new participants.

We provide certain health care benefits for eligible U.S. retired employees, their beneficiaries and covered dependents ("other postretirement benefits"). The health care plan is contributory and unfunded. On October 1, 2013, a change was made to postretirement medical benefits to limit the eligibility for the benefits beginning January 1, 2014 to include the following: (1) active employees whose age plus service, in years, equals or exceeds 80 (rule of 80); (2) active employees who are age 55 or older and have met the 15 years of service requirement; (3) active employees who will meet the rule of 80 in the next five years; (4) active employees who are age 55 or older and who will meet the 15 years of service requirement within the next five years; and (5) current retirees. Effective October 1, 2013, this change was accounted for as a negative plan amendment and resulted in a reduction to the postretirement benefit obligation of approximately $51 million, with an offset to accumulated other comprehensive income (AOCI). Starting in the fourth quarter of 2013, this reduction is being amortized as a reduction to net periodic benefit cost over three years. The postretirement plan obligation was remeasured using a discount rate of 4.75% as of October 1, 2013. For certain employees and former employees, additional coverage is provided for all medical expenses for life.

Pension and other postretirement benefit expenses, included in acquisition and operating expenses in the consolidated statement of earnings, included the following components:

During the three months ended March 31, 2015, Aflac Japan contributed approximately $5 million (using the weighted-average yen/dollar exchange rate for the three-month period ending March 31, 2015) to the Japanese funded defined benefit plan, and Aflac U.S. did not make a contribution to the U.S. funded defined benefit plan.

COMMITMENTS AND CONTINGENT LIABILITIES

We are a defendant in various lawsuits considered to be in the normal course of business. Members of our senior legal and financial management teams review litigation on a quarterly and annual basis. The final results of any litigation cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, we believe the outcome of pending litigation will not have a material adverse effect on our financial position, results of operations, or cash flows.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Fair Value Hierarchy

GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. These two types of inputs create three valuation hierarchy levels. Level 1 valuations reflect quoted market prices for identical assets or liabilities in active markets. Level 2 valuations reflect quoted market prices for similar assets or liabilities in an active market, quoted market prices for identical or similar assets or liabilities in non-active markets or model-derived valuations in which all significant valuation inputs are observable in active markets. Level 3 valuations reflect valuations in which one or more of the significant inputs are not observable in an active market.

The following tables present the fair value hierarchy levels of the Company's assets and liabilities that are measured and carried at fair value on a recurring basis.

Fair Value of Financial Instruments

U.S. GAAP requires disclosure of the fair value of certain financial instruments including those that are not carried at fair value. The carrying amounts for cash and cash equivalents, other investments, receivables, accrued investment income, accounts payable, cash collateral and payables for security transactions approximated their fair values due to the short-term nature of these instruments. Liabilities for future policy benefits and unpaid policy claims are not financial instruments as defined by GAAP.

Fixed maturities, perpetual securities, and equity securities

We determine the fair values of our fixed maturity securities, perpetual securities, and public and privately issued equity securities using the following approaches or techniques: price quotes and valuations from third party pricing vendors (including quoted market prices readily available from public exchange markets) and non-binding price quotes we obtain from outside brokers.

A third party pricing vendor has developed valuation models to determine fair values of privately issued securities to reflect the impact of the persistent economic environment and the changing regulatory framework. These models are discounted cash flow (DCF) valuation models, but also use information from related markets, specifically the CDS market to estimate expected cash flows. These models take into consideration any unique characteristics of the securities and make various adjustments to arrive at an appropriate issuer-specific loss adjusted credit curve.This credit curve is then used with the relevant recovery rates to estimate expected cash flows and modeling of additional features, including illiquidity adjustments, if necessary, to price the security by discounting those loss adjusted cash flows. In cases where a credit curve cannot be developed from the specific security features, the valuation methodology takes into consideration other market observable inputs, including: 1) the most appropriate comparable security(ies) of the issuer; 2) issuer-specific CDS spreads; 3) bonds or CDS spreads of comparable issuers with similar characteristics such as rating, geography, or sector; or 4) bond indices that are comparative in rating, industry, maturity and region.

The pricing data and market quotes we obtain from outside sources, including third party pricing services, are reviewed internally for reasonableness. If a fair value appears unreasonable, we will re-examine the inputs and assess the reasonableness of the pricing data with the vendor. Additionally, we may compare the inputs to relevant market indices and other performance measurements. The output of this analysis is presented to the Company's Valuation and Classifications Subcommittee, or VCS. Based on the analysis provided to the VCS, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. We have performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value.

The fixed maturities classified as Level 3 consist of securities for which there are limited or no observable valuation inputs. For Level 3 securities that are investment grade, we estimate the fair value of these securities by obtaining non-binding broker quotes from a limited number of brokers. These brokers base their quotes on a combination of their knowledge of the current pricing environment and market conditions. We consider these inputs to be unobservable. For Level 3 investments that are below-investment-grade securities, we consider a variety of significant valuation inputs in the valuation process, including forward exchange rates, yen swap rates, dollar swap rates, interest rate volatilities, credit spread data on specific issuers, assumed default and default recovery rates, and certain probability assumptions. In obtaining these valuation inputs, we have determined that certain pricing assumptions and data used by our pricing sources are difficult to validate or corroborate by the market and/or appear to be internally developed rather than observed in or corroborated by the market. The use of these unobservable valuation inputs causes more subjectivity in the valuation process for these securities.

Historically, we have not adjusted the quotes or prices we obtain from the pricing services and brokers we use.

The following is a discussion of the determination of fair value of our remaining financial instruments.

Derivatives

We use derivative instruments to manage the risk associated with certain assets. However, the derivative instrument may not be classified in the same fair value hierarchy level as the associated asset. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility.

The fair values of the foreign currency forwards, options, and interest rate swaptions associated with certain fixed-maturity securities; the foreign currency forwards used to hedge certain portions of forecasted yen cash flows; and the foreign currency swaps associated with certain senior notes and our subordinated debentures are based on the amounts we would expect to receive or pay. The determination of the fair value of these derivatives is based on observable market inputs, therefore they are classified as Level 2.

For derivatives associated with VIEs where we are the primary beneficiary, we are not the direct counterparty to the swap contracts. As a result, the fair value measurements incorporate the credit risk of the collateral associated with the VIE. We receive valuations from a third party pricing vendor for these derivatives. Based on an analysis of these derivatives and a review of the methodology employed by the pricing vendor, we determined that due to the long duration of these swaps and the need to extrapolate from short-term observable data to derive and measure long-term inputs, certain inputs, assumptions and judgments are required to value future cash flows that cannot be corroborated by current inputs or current observable market data. As a result, the derivatives associated with our consolidated VIEs are classified as Level 3 of the fair value hierarchy.

Other policyholders' funds

The largest component of the other policyholders' funds liability is our annuity line of business in Aflac Japan. Our annuities have fixed benefits and premiums. For this product, we estimated the fair value to be equal to the cash surrender value. This is analogous to the value paid to policyholders on the valuation date if they were to surrender their policy. We periodically check the cash value against discounted cash flow projections for reasonableness. We consider our inputs for this valuation to be unobservable and have accordingly classified this valuation as Level 3.

Notes payable

The fair values of our publicly issued notes payable classified as Level 3 were obtained from a limited number of independent brokers. These brokers base their quotes on a combination of their knowledge of the current pricing environment and market conditions. We consider these inputs to be unobservable. The fair values of our yen-denominated loans approximate their carrying values.

Transfers between Hierarchy Levels and Level 3 Rollforward

There were no transfers between Level 1 and 2 for the three-month periods ended March 31, 2015 and 2014.

The following is a discussion of the significant unobservable inputs or valuation technique used in determining the fair value of securities and derivatives classified as Level 3.

Net Asset Value

We hold certain unlisted equity securities whose fair value is derived based on the financial statements published by the investee. These securities do not trade on an active market and the valuations derived are dependent on the availability of timely financial reporting of the investee. Net asset value is an unobservable input in the determination of fair value ofequity securities.

Offered Quotes

In circumstances where our valuation model price is overridden because it implies a value that is not consistent with current market conditions, we will solicit bids from a limited number of brokers. We also receive unadjusted prices from brokers for our mortgage and asset-backed securities. These quotes are non-binding but are reflective of valuation best estimates at that particular point in time. Offered quotes are an unobservable input in the determination of fair value of mortgage- and asset-backed securities, certain banks/financial institutions, certain other corporate, and equity securities investments.

Interest Rates, CDS Spreads, Foreign Exchange Rates

The significant drivers of the valuation of the interest and foreign exchange swaps are interest rates, foreign exchange rates and CDS spreads. Our swaps have long maturities that increase the sensitivity of the swaps to interest rate fluctuations. Since most of our yen-denominated cross currency swaps are in a net liability position, an increase in interest rates will decrease the liabilities and increase the value of the swap.

Foreign exchange swaps also have a lump-sum final settlement of foreign exchange principal receivables at the termination of the swap. An increase in yen interest rates will decrease the value of the final settlement foreign exchange receivables and decrease the value of the swap, and an increase in USD interest rates increase the swap value.

A similar sensitivity pattern is observed for the foreign exchange rates. When the spot U.S. dollar/Japanese yen (USD/JPY) foreign exchange rate decreases and the swap is receiving a final exchange payment in JPY, the swap value will increase due to the appreciation of the JPY. Most of our swaps are designed to receive payments in JPY at the termination and will thus be impacted by the USD/JPY foreign exchange rate in this way. In cases where there is no final foreign exchange receivable in JPY and we are paying JPY as interest payments and receiving USD, a decrease in the foreign exchange rate will lead to a decrease in the swap value.

The extinguisher feature in most of our swaps results in a cessation of cash flows and no further payments between the parties to the swap in the event of a default on the referenced or underlying collateral. To price this feature, we apply the survival probability of the referenced entity to the projected cash flows. The survival probability uses the CDS spreads and recovery rates to adjust the present value of the cash flows. For extinguisher swaps with positive values, an increase in CDS spreads decreases the likelihood of receiving the final exchange payments and reduces the value of the swap.

Due to the long duration of these swaps and the need to extrapolate from short-term observable data to derive and measure long-term inputs, certain inputs, assumptions and judgments are required to value future cash flows that cannot be corroborated by current inputs or current observable market data.

Interest rates, CDS spreads, and foreign exchange rates are unobservable inputs in the determination of fair value of foreign currency swaps.

Base Correlations, CDS Spreads, Recovery Rates

Our CDOs are tranches on baskets of single-name credit default swaps. The risks in these types of synthetic CDOs come from the single-name CDS risk and the correlations between the single names. The valuation of synthetic CDOs is dependent on the calibration of market prices for interest rates, single name CDS default probabilities and base correlation using financial modeling tools. Since there is limited or no observable data available for these tranches, these base correlations must be obtained from commonly traded market tranches such as the CDX and iTraxx indices. From the historical prices of these indices, base correlations can be obtained to develop a pricing curve of CDOs with different seniorities. Since the reference entities of the market indices do not match those in our portfolio underlying the synthetic CDO to be valued, several processing steps are taken to map the securities in our portfolio to the indices. With the base correlation determined and the appropriate spreads selected, a valuation is calculated. An increase in the CDS spreads in the underlying portfolio leads to a decrease in the value due to higher probability of defaults and losses. The impact on the valuation due to base correlation depends on a number of factors, including the riskiness between market tranches and the modeled tranche based on our portfolio and the equivalence between detachment points in these tranches. Generally speaking, an increase in base correlation will decrease the value of the senior tranches while increasing the value of junior tranches. This may result in a positive or negative value change.

The CDO tranches in our portfolio are junior tranches and, due to the low level of credit support for these tranches, exhibit equity-like behavior. As a result, an increase in recovery rates tends to cause their values to decrease.

Our interest rate swaps are linked to the underlying synthetic CDOs. The valuation of these swaps is performed using a similar approach to that of the synthetic CDOs themselves; that is, the base correlation model is used to ensure consistency between the synthetic CDOs and the swaps.

Base correlations, CDS spreads, and recovery rates are unobservable inputs in the determination of fair value of credit default swaps.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE INSTRUMENTS

DERIVATIVE INSTRUMENTS

Our freestanding derivative financial instruments consist of: (1) foreign currency swaps and credit default swaps that are associated with investments in special-purpose entities, including VIEs where we are the primary beneficiary; (2) foreign currency forwards and options used in hedging foreign exchange risk on U.S. dollar-denominated securities in Aflac Japan's portfolio; (3) foreign currency forwards used to hedge certain portions of forecasted cash flows denominated in yen; (4) swaps associated with our notes payable, consisting of cross-currency interest rate swaps, also referred to as foreign currency swaps, associated with certain senior notes and our subordinated debentures; and (5) options on interest rate swaps (or interest rate swaptions) and futures used to hedge interest rate risk for certain available-for-sale securities. We do not use derivative financial instruments for trading purposes, nor do we engage in leveraged derivative transactions. Some of our derivatives are designated as cash flow hedges, fair value hedges or net investment hedges; however, other derivatives do not qualify for hedge accounting. We utilize a net investment hedge to mitigate foreign exchange exposure resulting from our net investment in Aflac Japan. In addition to designating derivatives as hedging instruments, we have designated our yen-denominated Samurai and Uridashi notes and yen-denominated loans as nonderivative hedging instruments for this net investment hedge.

We enter into foreign currency swaps pursuant to which we exchange an initial principal amount in one currency for an initial principal amount of another currency, with an agreement to re-exchange the currencies at a future date at an agreed upon exchange rate. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Foreign currency swaps are used primarily in the consolidated VIEs in our Aflac Japan portfolio to convert foreign-denominated cash flows to yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. We also use foreign currency swaps to economically convert certain of our dollar-denominated senior note and subordinated debenture principal and interest obligations into yen-denominated obligations.

Foreign currency forwards and options with short-term maturities are executed for the Aflac Japan segment in order to hedge the currency risk on the fair value of certain fixed-maturity dollar-denominated securities. In forward transactions, Aflac Japan agrees with another party to buy a fixed amount of yen and sell a corresponding amount of U.S. dollars at a specified future date. Aflac Japan also executes foreign currency option transactions in a collar strategy, where Aflac Japan agrees with another party to simultaneously purchase a fixed amount of U.S. dollar put options and sell U.S. dollar call options. The combination of these two actions results in no net premium being paid (i.e. a costless or zero-cost collar). The foreign currency forwards and options are used in fair value hedging relationships to mitigate the foreign exchange risk associated with dollar-denominated investments supporting yen-denominated liabilities.

Foreign currency forwards are also used to hedge the currency risk associated with the net investment in Aflac Japan. In these forward transactions, Aflac agrees with another party to buy a fixed amount of U.S. dollars and sell a corresponding amount of yen at a specified future date.

Our CDS is used to assume credit risk related to an individual security. The only CDS derivative that we have entered into relates to components of an investment in a VIE. This CDS contract entitles the consolidated VIE to receive periodic fees in exchange for an obligation to compensate the derivative counterparties should the reference security issuers experience a credit event, as defined in the contract.

Interest rate swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. No cash or principal payments are exchanged at the inception of the contract. Interest rate swaps are primarily used to convert interest receipts on floating-rate fixed-maturity securities contracts to fixed rates. These derivatives are predominantly used to better match cash receipts from assets with cash disbursements required to fund liabilities.

Interest rate swaptions are options on interest rate swaps. Interest rate collars are combinations of two swaption positions and are executed in order to hedge certain dollar-denominated available-for-sale securities that are held in the Aflac Japan segment. We use collars to protect against significant changes in the fair value associated with interest rate changes of our dollar-denominated available-for-sale securities. In order to maximize the efficiency of the collars while minimizing cost, we set the strike price on each collar so that the premium paid for the ‘payer leg’ is offset by the premium received for having sold the ‘receiver leg’.

Periodically, depending on general economic conditions, we may enter into other derivative transactions.

Credit Risk Assumed through Derivatives

For the foreign currency and credit default swaps associated with our VIE investments for which we are the primary beneficiary, we bear the risk of foreign exchange loss due to counterparty default even though we are not a direct counterparty to those contracts. We are a direct counterparty to the foreign currency swaps that we have entered into in connection with certain of our senior notes, subordinated debentures, and Samurai notes; foreign currency forwards; foreign currency options; and interest rate swaptions, and therefore we are exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for our VIE swaps, foreign currency swaps, certain foreign currency forwards, foreign currency options and interest rate swaptions is mitigated by collateral posting requirements the counterparties to those transactions must meet. As of March 31, 2015, there were 16 counterparties to our derivative agreements, with five comprising 75% of the aggregate notional amount. The counterparties to these derivatives are financial institutions with the following credit ratings:

	March 31, 2015										December 31, 2014
(In millions)	Notional Amount of Derivatives			Asset Derivatives Fair Value			Liability Derivatives Fair Value				Notional Amount of Derivatives			Asset Derivatives Fair Value			Liability Derivatives Fair Value

Total		$	23,398		$	706		$	(599	)		$	23,662		$	802		$	(2,423	)

We engage in derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annex (CSA) provisions, which generally provide for two-way collateral postings, in certain cases at the first dollar of exposure and in other cases once various rating and exposure threshold levels are triggered. We mitigate the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction or that additional collateral be posted upon the occurrence of certain events or circumstances. In addition, a significant portion of the derivative transactions have provisions that require collateral to be posted upon a downgrade of our long-term debt ratings or give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of collateral required to be posted to counterparties in the event of such downgrades, or the aggregate amount of payments that we could be required to make, depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade.

Collateral posted by us to third parties for derivative transactions was $87 million and $1.6 billion at March 31, 2015 and December 31, 2014, respectively, which consisted entirely of pledged securities. This collateral can generally be repledged or resold by the counterparties. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position by counterparty was $196 million and $2.1 billion as of March 31, 2015 and December 31, 2014, respectively. If the credit-risk-related contingent features underlying these agreements had been triggered on March 31, 2015, we estimate that we would be required to post a maximum of $109 million of additional collateral to these derivative counterparties. Collateral obtained by us from third parties for derivative transactions was $552 million and $619 million at March 31, 2015 and December 31, 2014, respectively. We generally can repledge or resell collateral obtained by us, although we do not typically exercise such rights.

Accounting for Derivative Financial Instruments

Freestanding derivatives are carried at estimated fair value in our consolidated balance sheets either as assets within other assets or as liabilities within other liabilities. See Note 5 for a discussion on how we determine the fair value of our derivatives. Accruals on derivatives are recorded in accrued investment income or within other liabilities in the consolidated balance sheets.

If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are generally reported within derivative and other gains(losses), which is a component of realized investment gains (losses). The fluctuations in estimated fair value of derivatives that have not been designated for hedge accounting can result in volatility in net earnings.

Hedge Documentation and Effectiveness Testing

To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated risk of the hedged item. At the inception of the hedging relationship, we formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking each hedge transaction. We document the designation of each hedge as either (i) a hedge of the variability of cash flows to be received or paid related to a recognized asset or liability or the hedge of a forecasted transaction ("cash flow hedge"); (ii) a hedge of the estimated fair value of a recognized asset or liability ("fair value hedge"); or (iii) a hedge of a net investment in a foreign operation. The documentation process includes linking derivatives and nonderivatives that are designated as hedges to specific assets or groups of assets or liabilities on the statement of financial position or to specific forecasted transactions and defining the effectiveness and ineffectiveness testing methods to be used. At the hedge's inception and on an ongoing quarterly basis, we also formally assess whether the derivatives that are used in hedging transactions have been, and are expected to continue to be, highly effective in offsetting their designated risk. Hedge effectiveness is assessed using qualitative and quantitative methods.

For assessing hedge effectiveness of cash flow hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression or other statistical analysis of changes in cash flows associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships on our VIE cash flow hedge is measured each reporting period using the “Hypothetical Derivative Method.” For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing hedge ineffectiveness are recognized in current earnings within derivative and other gains (losses). All components of each derivative's gain or loss are included in the assessment of hedge effectiveness.

For assessing hedge effectiveness of fair value hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression or other statistical analysis of changes in fair value associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships is measured each reporting period using the dollar offset method. For derivative instruments that are designated and qualify as fair value hedges, changes in the estimated fair value of the derivative, including amounts measured as ineffectiveness, and changes in the estimated fair value of the hedged item related to the designated risk being hedged, are reported in current earnings within derivative and other gains (losses).

For the hedge of our net investment in Aflac Japan, we have designated Parent Company yen-denominated liabilities as non-derivative hedging instruments and have designated certain foreign currency forwards and options as derivative hedging instruments. We make our net investment hedge designation at the beginning of each quarter. For assessing hedge effectiveness of net investment hedges, if the total of the designated Parent Company non-derivative and derivatives notional is equal to or less than our net investment in Aflac Japan, the hedge is deemed to be effective. If the hedge is effective, the related exchange effect on the yen-denominated liabilities is reported in the unrealized foreign currency component of other comprehensive income. For derivatives designated as net investment hedges, Aflac follows the forward-rate method. According to that method, all changes in fair value, including changes related to the forward-rate component of foreign currency forward contracts and the time value of foreign currency options, are reported in the unrealized foreign currency component of other comprehensive income. Should these designated net investment hedge positions exceed our net investment in Aflac Japan, the foreign exchange effect on the portion that exceeds our investment in Aflac Japan would be recognized in current earnings within derivative and other gains (losses).

Discontinuance of Hedge Accounting

We discontinue hedge accounting prospectively when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the estimated cash flows or fair value of a hedged item; (2) the derivative is de-designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised.

When hedge accounting is discontinued on a cash flow hedge or fair value hedge, the derivative is carried in the consolidated balance sheets at its estimated fair value, with changes in estimated fair value recognized in current period earnings. For discontinued cash flow hedges, including those where the derivative is sold, terminated or exercised, amounts previously deferred in other comprehensive income (loss) are reclassified into earnings when earnings are impacted by the cash flow of the hedged item.

Derivative Balance Sheet Classification

The tables below summarize the balance sheet classification of our derivative fair value amounts, as well as the gross asset and liability fair value amounts. The fair value amounts presented do not include income accruals. The notional amount of derivative contracts represents the basis upon which pay or receive amounts are calculated. Notional amounts are not reflective of credit risk.

Cash Flow Hedges

Certain of our consolidated VIEs have foreign currency swaps that qualify for hedge accounting treatment. For those that have qualified, we have designated the derivative as a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset (“cash flow” hedge). We expect to continue this hedging activity for a weighted-average period of approximately 11 years. The remaining derivatives in our consolidated VIEs that have not qualified for hedge accounting have been designated as held for other investment purposes (“non-qualifying strategies”).

Fair Value Hedges

We designate and account for certain foreign currency forwards and options as fair value hedges when they meet the requirements for hedge accounting. These foreign currency forwards and options hedge the foreign currency exposure of certain dollar-denominated fixed maturity securities within the investment portfolio of our Aflac Japan segment. We recognize gains and losses on these derivatives and the related hedged items in current earnings within derivative and other gains (losses). The change in the fair value of the foreign currency forwards related to the changes in the difference between the spot rate and the forward price is excluded from the assessment of hedge effectiveness. The change in fair value of the foreign currency option related to the time value of the option is excluded from the assessment of hedge effectiveness.

We designate and account for interest rate swaptions as fair value hedges when they meet the requirements for hedge accounting. These interest rate swaptions hedge the interest rate exposure of certain dollar-denominated fixed maturity securities within the investment portfolio of our Aflac Japan segment. We recognize gains and losses on these derivatives and the related hedged items in current earnings within derivative and other gains (losses). The change in the fair value of the interest rate swaptions related to the time value of the option is excluded from the assessment of hedge effectiveness.

The following table presents the gains and losses on derivatives and the related hedged items in fair value hedges.

Net Investment Hedge

Our primary exposure to be hedged is our net investment in Aflac Japan, which is affected by changes in the yen/dollar exchange rate. To mitigate this exposure, we have designated the Parent Company's yen-denominated liabilities (Samurai and Uridashi notes and yen-denominated loans - see Note 7) as nonderivative hedges and designated foreign currency forwards and, in prior periods, options as derivative hedges of the foreign currency exposure of our net investment in Aflac Japan.

We used foreign exchange forwards to economically hedge foreign exchange risk on 30.0 billion yen of profit repatriation received from Aflac Japan in February 2015. As of March 31, 2015, we had entered into foreign exchange forwards as part of an economic hedge on 157.5 billion yen of future profit repatriation.

Our net investment hedge was effective during the three-month periods ended March 31, 2015 and 2014.

Non-qualifying Strategies

For our derivative instruments in consolidated VIEs that do not qualify for hedge accounting treatment, all changes in their fair value are reported in current period earnings within derivative and other gains (losses). The amount of gain or loss recognized in earnings for our VIEs is attributable to the derivatives in those investment structures. While the change in value of the swaps is recorded through current period earnings, the change in value of the available-for-sale fixed-maturity or perpetual securities associated with these swaps is recorded through other comprehensive income.

We have cross-currency interest rate swap agreements related to our $400 million senior notes due February 2017, $550 million senior notes due March 2020, $350 million senior notes due February 2022, $700 million senior notes due June 2023, $750 million senior notes due November 2024, $450 million senior notes due March 2025, and $500 million subordinated debentures due September 2052. Changes in the values of these swaps are recorded through current period earnings.

For additional information regarding these swaps, see Note 7 in this report and Note 9 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2014.

⁽²⁾ Impact shown net of effect of hedged items (see Fair Value Hedges section of this Note 4 for further detail)

There was no gain or loss reclassified from accumulated other comprehensive income (loss) into earnings related to our designated cash flow hedges and net investment hedge for the three-month periods ended March 31, 2015 and 2014. As of March 31, 2015, deferred gains and losses on derivative instruments recorded in accumulated other comprehensive income that are expected to be reclassified to earnings during the next twelve months were immaterial.

Offsetting of Financial Instruments and Derivatives

Certain of the Company's derivative instruments are subject to enforceable master netting arrangements that provide for the net settlement of all derivative contracts between the Parent Company or Aflac and its respective counterparty in the event of default or upon the occurrence of certain termination events. Collateral support agreements with certain of the master netting arrangements provide that the Company will receive or pledge financial collateral in the event either minimum thresholds, or in certain cases ratings levels, have been reached.

We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities (see Note 3). When we have entered into securities lending agreements with the same counterparty, the agreements generally provide for net settlement in the event of default by the counterparty. This right of set-off would allow us to keep and apply collateral received if the counterparty failed to return the securities borrowed from us as contractually agreed.

The tables below summarize our derivatives and securities lending transactions, and as reflected in the tables, in accordance with GAAP, our policy is to not offset these financial instruments in the Consolidated Balance Sheets.

SUBSEQUENT EVENTS

Effective April 1, 2015, we entered into a retrocession coinsurance reinsurance transaction whereby we assumed 90.0% of the reinsured sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business through our subsidiary CAIC. This business was originally ceded on March 31, 2015 as described in Note 6.

In April 2015, the Parent Company used the proceeds from the March 2015 issuance of its fixed-rate senior notes to redeem $850 million of our 8.50% fixed-rate senior notes due May 2019 and to pay a portion of the corresponding $230 million make-whole premium due to the investors of these notes.

Reinsurance Disclosures [Abstract]

REINSURANCE

REINSURANCE

Effective March 31, 2015, we entered into a coinsurance reinsurance transaction whereby we ceded 30.0% of the sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business. We recorded the gain related to this transaction as a deferred profit liability on business sold through reinsurance on our consolidated balance sheets. The deferred profit liability of $600 million, as of March 31, 2015, included in future policy benefits in the consolidated balance sheet, is being amortized into income over the expected lives of the policies. The corresponding reinsurance recoverable is included in other assets in the consolidated balance sheet and totaled $600 million as of March 31, 2015. As of March 31, 2015, no ceded premiums or claims have been incurred or paid under the transaction.

Effective October 1, 2014 and September 30, 2013, we entered into coinsurance reinsurance transactions whereby we ceded 16.7% and 33.3%, respectively, of the hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business. We recorded the gain related to these transactions as a deferred profit liability on business sold through reinsurance on our consolidated balance sheets. The deferred profit liability of $684 million, as of March 31, 2015, included in future policy benefits in the consolidated balance sheet, is being amortized into income over the expected lives of the policies. The corresponding reinsurance recoverable is included in other assets in the consolidated balance sheet and totaled $707 million as of March 31, 2015.

Effective December 31, 2014, we entered into a retrocession coinsurance reinsurance transaction whereby we assumed 8.35% of the reinsured hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business through our subsidiary CAIC. The corresponding future policy benefit liability of $3 million, as of March 31, 2015, was included in future policy benefits in the consolidated balance sheet.

The following table reconciles direct premium income and direct benefits and claims to net amounts after the effect of reinsurance.

In March 2015, the Parent Company issued two series of senior notes totaling $1.0 billion through a U.S. public debt offering. The first series, which totaled $550 million, bears interest at a fixed rate of 2.40% per annum, payable semi-annually, and has a five-year maturity. The second series, which totaled $450 million, bears interest at a fixed rate of 3.25% per annum, payable semi-annually, and has a ten-year maturity. We have entered into cross-currency swaps that convert the dollar-denominated principal and interest on the senior notes into yen-denominated obligations which results in lower nominal net interest rates on the debt. By entering into these cross-currency swaps, we economically converted our $550 million liability into a 67.0 billion yen liability and reduced the interest rate on this debt from 2.40% in dollars to .24% in yen, and we economically converted our $450 million liability into a 55.0 billion yen liability and reduced the interest rate on this debt from 3.25% in dollars to .82% in yen.

In February 2015, the Parent Company and Aflac jointly entered into an uncommitted bank line of credit with a third party that provides for borrowings in the amount of $50 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expenses or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of March 31, 2015, we did not have any borrowings outstanding under our $50 million credit agreement.

The Parent Company and Aflac have an uncommitted bilateral line of credit that provides for borrowings in the amount of $100 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expense or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of March 31, 2015, we did not have any borrowings outstanding under our $100 million credit agreement. Borrowings under the financing agreement will mature no later than three months after the last drawdown date of October 15, 2015.

The Parent Company and Aflac have a senior unsecured revolving credit facility agreement with a syndicate of financial institutions that provides for borrowings in the amount of 50 billion yen. This credit agreement provides for borrowings in Japanese yen or the equivalent of Japanese yen in U.S. dollars on a revolving basis. Borrowings will bear interest at LIBOR plus the applicable margin of 1.125%. In addition, the Parent Company and Aflac are required to pay a facility fee of .125% on the commitments. As of March 31, 2015, we did not have any borrowings outstanding under our 50 billion yen revolving credit agreement. Borrowings under the credit agreement may be used for general corporate purposes, including a capital contingency plan for our Japanese operations. Borrowings under the financing agreement mature at the termination date of the credit agreement. The agreement requires compliance with certain financial covenants on a quarterly basis. This credit agreement will expire on the earlier of March 29, 2018, or the date of termination of the commitments upon an event of default as defined in the agreement.

We were in compliance with all of the covenants of our notes payable and lines of credit at March 31, 2015. No events of default or defaults occurred during the three-month period ended March 31, 2015.

SHARE-BASED COMPENSATION

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION

As of March 31, 2015, the Company has outstanding share-based awards under two long-term incentive compensation plans.

The first plan, which expired in February 2007, is a stock option plan which allowed grants for incentive stock options (ISOs) to employees and non-qualifying stock options (NQSOs) to employees and non-employee directors. The options have a term of 10 years. The exercise price of options granted under this plan is equal to the fair market value of a share of the Company's common stock at the date of grant. Options granted before the plan's expiration date remain outstanding in accordance with their terms.

The second long-term incentive compensation plan allows awards to Company employees for ISOs, NQSOs, restricted stock, restricted stock units, and stock appreciation rights. Non-employee directors are eligible for grants of NQSOs, restricted stock, and stock appreciation rights. The ISOs and NQSOs have a term of 10 years, and the share-based awards generally vest based upon time-based conditions or time- and performance-based conditions. Time-based vesting generally occurs after three years. Performance-based vesting conditions generally include the attainment of goals related to Company financial performance. As of March 31, 2015, approximately 10.1 million shares were available for future grants under this plan, and the only performance-based awards issued and outstanding were restricted stock awards.

Share-based awards granted to U.S.-based grantees are settled with authorized but unissued Company stock, while those issued to Japan-based grantees are settled with treasury shares.

The following table provides information on stock options outstanding and exercisable at March 31, 2015.

	Stock Option Shares (in thousands)		Weighted-Average Remaining Term (in years)		Aggregate Intrinsic Value (in millions)			Weighted-Average Exercise Price Per Share
Outstanding		9,388		4.8		$	131		$	50.04
Exercisable		7,349		3.6		118			47.94

We received cash from the exercise of stock options in the amount of $22 million during the first three months of 2015, compared with $18 million in the first three months of 2014. The tax benefit realized as a result of stock option exercises and restricted stock releases was $15 million in the first three months of 2015, compared with $11 million in the first three months of 2014.

As of March 31, 2015, total compensation cost not yet recognized in our financial statements related to restricted stock awards was $64 million, of which $26 million (780 thousand shares) was related to restricted stock awards with a performance-based vesting condition. We expect to recognize these amounts over a weighted-average period of approximately 1.8 years. There are no other contractual terms covering restricted stock awards once vested.

For additional information on our long-term share-based compensation plans and the types of share-based awards, see Note 12 of the Notes to the Consolidated Financial Statements included in our annual report to shareholders for the year ended December 31, 2014.

The methods of determining the fair values of our investments in fixed-maturity securities, perpetual securities and equity securities are described in Note 5.

During the first quarter of 2015, we did not reclassify any investments from the held-to-maturity category to the available-for-sale category. During the first quarter of 2014, we reclassified one investment from the held-to-maturity category to the available-for-sale category as a result of the issuer being downgraded to below investment grade. At the time of transfer, the security had an amortized cost of $63 million and an unrealized loss of $8 million.

Contractual and Economic Maturities

The contractual maturities of our investments in fixed maturities at March 31, 2015, were as follows:

	Aflac Japan						Aflac U.S.
(In millions)	Amortized Cost			Fair Value			Amortized Cost			Fair   Value

At March 31, 2015, the Parent Company had a portfolio of available-for-sale fixed-maturity securities totaling $476 million at amortized cost and $498 million at fair value, which is not included in the table above.

Expected maturities may differ from contractual maturities because some issuers have the right to call or prepay obligations with or without call premiums or prepayment penalties.

The majority of our perpetual securities are subordinated to other debt obligations of the issuer, but rank higher than the issuer's equity securities. Perpetual securities have characteristics of both debt and equity investments, along with unique features that create economic maturity dates for the securities. Although perpetual securities have no contractual maturity date, they have stated interest coupons that were fixed at their issuance and subsequently change to a floating short-term interest rate after some period of time. The instruments are generally callable by the issuer at the time of changing from a fixed coupon rate to a new variable rate of interest, which is determined by the combination of some market index plus a fixed amount of basis points. The net effect is to create an expected maturity date for the instrument. The economic maturities of our investments in perpetual securities, which were all reported as available for sale at March 31, 2015, were as follows:

Investment Concentrations

Our process for credit-related investments begins with an independent approach to underwriting each issuer's fundamental credit quality. We evaluate independently those factors which we believe could influence an issuer's ability to make payments under the contractual terms of our instruments. This includes a thorough analysis of a variety of items including the issuer's country of domicile (including political, legal, and financial considerations); the industry in which the issuer competes (with an analysis of industry structure, end-market dynamics, and regulation); company specific issues (such as management, assets, earnings, cash generation, and capital needs); and contractual provisions of the instrument (such as financial covenants and position in the capital structure). We further evaluate the investment considering broad business and portfolio management objectives, including asset/liability needs, portfolio diversification, and expected income.

Banks and Financial Institutions

One of our largest investment sector concentrations as of March 31, 2015, was banks and financial institutions. Within the countries we approve for investment opportunities, we primarily invest in financial institutions that are strategically crucial to each approved country's economy. The bank and financial institution sector is a highly regulated industry and plays a strategic role in the global economy.

Our total investments in the bank and financial institution sector, including those classified as perpetual securities, were as follows:

Other-than-temporary Impairment

The fair values of our debt and perpetual security investments fluctuate based on changes in interest rates, foreign exchange, and credit spreads in the global financial markets. Fair values can also be heavily influenced by the values of the assets of the issuer and expected ultimate recovery values upon default, bankruptcy or other financial restructuring. Credit spreads are most impacted by the general credit environment and global market liquidity. Interest rates are driven by numerous factors including, but not limited to, supply and demand, governmental monetary actions, expectations of inflation and economic growth. We believe that fluctuations in the fair values of our investment securities related to general changes in the level of credit spreads or interest rates have little bearing on underlying credit quality of the issuer, and whether our investment is ultimately recoverable. Generally, we consider such declines in fair values to be temporary even in situations where an investment remains in an unrealized loss position for a year or more.

However, in the course of our credit review process, we may determine that it is unlikely that we will recover our investment in an issuer due to factors specific to an individual issuer, as opposed to general changes in global credit spreads or interest rates. In this event, we consider such a decline in the investment's fair value, to the extent it is below the investment's cost or amortized cost, to be an other-than-temporary impairment of the investment and reduce the book value of the investment to its fair value.

In addition to the usual investment risk associated with a debt instrument, our perpetual security holdings are largely issued by banks that are integral to the financial markets of the sovereign country of the issuer. As a result of the issuer's position within the economy of the sovereign country, our perpetual securities may be subject to a higher risk of nationalization of their issuers in connection with capital injections from an issuer's sovereign government. We cannot be assured that such capital support will extend to all levels of an issuer's capital structure. In addition, certain governments or regulators may consider imposing interest and principal payment restrictions on issuers of hybrid securities to preserve cash and preserve the issuer's capital. Beyond the cash flow impact that additional deferrals would have on our portfolio, such deferrals could result in ratings downgrades of the affected securities, which in turn could result in a reduction of fair value of the securities and increase our regulatory capital requirements. We consider these factors in our credit review process.

When determining our intention to sell a security prior to recovery of its fair value to amortized cost, we evaluate facts and circumstances such as, but not limited to, future cash flow needs, decisions to reposition our security portfolio, and risk profile of individual investment holdings. We perform ongoing analyses of our liquidity needs, which includes cash flow testing of our policy liabilities, debt maturities, projected dividend payments and other cash flow and liquidity needs. Our cash flow testing includes extensive duration analysis of our investment portfolio and policy liabilities. Based on our analyses, we have concluded that we have sufficient excess cash flows to meet our liquidity needs without selling any of our investments prior to their maturity.

Analysis of Securities in Unrealized Loss Positions

The unrealized losses on our investments have been primarily related to general market changes in interest rates, foreign exchange rates, and/or the levels of credit spreads rather than specific concerns with the issuer's ability to pay interest and repay principal.

For any significant declines in fair value, we perform a more focused review of the related issuers' credit profile. For corporate issuers, we evaluate their assets, business profile including industry dynamics and competitive positioning, financial statements and other available financial data. For non-corporate issuers, we analyze all sources of credit support, including issuer-specific factors. We utilize information available in the public domain and, for certain private placement issuers, from consultations with the issuers directly. We also consider ratings from the Nationally Recognized Statistical Rating Organizations (NRSROs), as well as the specific characteristics of the security we own including seniority in the issuer's capital structure, covenant protections, or other relevant features. From these reviews, we evaluate the issuers' continued ability to service our investment through payment of interest and principal.

The following table provides more information on our unrealized loss positions.

Assuming no credit-related factors develop, as investments near maturity, unrealized gains and losses are expected to diminish. Based on our credit analysis, we believe that the issuers of our investments in the sectors shown in the table above have the ability to service their obligations to us.

Perpetual Securities

The majority of our investments in Upper Tier II and Tier I perpetual securities were in highly-rated global financial institutions. Upper Tier II securities have more debt-like characteristics than Tier I securities and are senior to Tier I securities, preferred stock, and common equity of the issuer. Conversely, Tier I securities have more equity-like characteristics, but are senior to the common equity of the issuer. They may also be senior to certain preferred shares, depending on the individual security, the issuer's capital structure and the regulatory jurisdiction of the issuer.

Details of our holdings of perpetual securities were as follows:

Assuming no credit-related factors develop, as investments near maturity, the unrealized gains or losses are expected to diminish. Based on our credit analysis, we believe that the issuers of our investments in these sectors have the ability to service their obligations to us.

Variable Interest Entities (VIEs)

As a condition to our involvement or investment in a VIE, we enter into certain protective rights and covenants that preclude changes in the structure of the VIE that would alter the creditworthiness of our investment or our beneficial interest in the VIE.

Our involvement with all of the VIEs in which we have an interest is passive in nature, and we are not the arranger of these entities. We have not been involved in establishing these entities, except as it relates to our review and evaluation of the structure of these VIEs in the normal course of our investment decision-making process. Further, we are not, nor have we been, required to purchase any securities issued in the future by these VIEs.

Our ownership interest in the VIEs is limited to holding the obligations issued by them. All of the VIEs in which we invest are static with respect to funding and have no ongoing forms of funding after the initial funding date. We have no direct or contingent obligations to fund the limited activities of these VIEs, nor do we have any direct or indirect financial guarantees related to the limited activities of these VIEs. We have not provided any assistance or any other type of financing support to any of the VIEs we invest in, nor do we have any intention to do so in the future. The weighted-average lives of our notes are very similar to the underlying collateral held by these VIEs where applicable.

Our risk of loss related to our interests in any of our VIEs is limited to our investment in the debt securities issued by them.

VIEs - Consolidated

The following table presents the amortized cost, fair value and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported.

Investments in Consolidated Variable Interest Entities

	March 31, 2015						December 31, 2014
(In millions)	Amortized Cost			Fair Value			Amortized Cost			Fair Value
Assets:
Fixed maturities, available for sale		$	3,511		$	4,667		$	3,020		$	4,166
Perpetual securities, available for sale		406			432			405			429
Fixed maturities, held to maturity		83			83			83			84

Liabilities:
Other liabilities		$	392		$	392		$	318		$	318
Total liabilities of consolidated VIEs		$	392		$	392		$	318		$	318

We are substantively the only investor in the consolidated VIEs listed in the table above. As the sole investor in these VIEs, we have the power to direct the activities of a variable interest entity that most significantly impact the entity's economic performance and are therefore considered to be the primary beneficiary of the VIEs that we consolidate. We also participate in substantially all of the variability created by these VIEs. The activities of these VIEs are limited to holding debt and perpetual securities and foreign currency and/or credit default swaps (CDSs), as appropriate, and utilizing the cash flows from these securities to service our investment. Neither we nor any of our creditors are able to obtain the underlying collateral of the VIEs unless there is an event of default or other specified event. For those VIEs that contain a swap, we are not a direct counterparty to the swap contracts and have no control over them. Our loss exposure to these VIEs is limited to our original investment. Our consolidated VIEs do not rely on outside or ongoing sources of funding to support their activities beyond the underlying collateral and swap contracts, if applicable. With the exception of our investment in senior secured bank loans through unit trust structures, the underlying collateral assets and funding of our consolidated VIEs are generally static in nature and the underlying collateral and the reference corporate entities covered by any CDS contracts were all investment grade at the time of issuance.

We are exposed to credit losses within any consolidated collateralized debt obligations (CDOs) that could result in principal losses to our investments. We have mitigated our risk of credit loss through the structure of the VIE, which contractually requires the subordinated tranches within these VIEs to absorb the majority of the expected losses from the underlying credit default swaps. We currently own only senior mezzanine CDO tranches. Based on our statistical analysis models and the current subordination levels in our CDOs, each of these VIEs can sustain a reasonable number of defaults in the underlying reference entities in the CDSs with no loss to our investment.

VIEs-Not Consolidated

The table below reflects the amortized cost, fair value and balance sheet caption in which our investment in VIEs not consolidated are reported.

Investments in Variable Interest Entities Not Consolidated

	March 31, 2015						December 31, 2014
(In millions)	Amortized Cost			Fair Value			Amortized Cost			Fair Value
Assets:
Fixed maturities, available for sale		$	6,159		$	7,089		$	6,104		$	6,937
Perpetual securities, available for sale		312			324			324			330
Fixed maturities, held to maturity		2,488			2,736			2,564			2,829
Total investments in VIEs not consolidated		$	8,959		$	10,149		$	8,992		$	10,096

The VIEs that we are not required to consolidate are investments that are in the form of debt obligations from the VIEs that are irrevocably and unconditionally guaranteed by their corporate parents or sponsors. These VIEs are the primary financing vehicles used by their corporate sponsors to raise financing in the international capital markets. The variable interests created by these VIEs are principally or solely a result of the debt instruments issued by them. We do not have the power to direct the activities that most significantly impact the entity's economic performance, nor do we have (1) the obligation to absorb losses of the entity or (2) the right to receive benefits from the entity. As such, we are not the primary beneficiary of these VIEs and are therefore not required to consolidate them. These VIE investments comprise securities from 180 separate issuers with an average credit rating of BBB.

Securities Lending

We lend fixed-maturity securities to financial institutions in short-term security-lending transactions. These short-term security-lending arrangements increase investment income with minimal risk. Our security lending policy requires that the fair value of the securities and/or unrestricted cash received as collateral be 102% or more of the fair value of the loaned securities.

These securities continue to be carried as investment assets on our balance sheet during the terms of the loans and are not reported as sales. We receive cash or other securities as collateral for such loans. For loans involving unrestricted cash or securities as collateral, the collateral is reported as an asset with a corresponding liability for the return of the collateral.

The following table presents our security loans outstanding and the corresponding collateral held:

(In millions)	March 31, 2015			December 31, 2014
Security loans outstanding, fair value		$	2,558		$	2,149
Cash collateral on loaned securities		2,615			2,193

Certain fixed-maturity securities have been pledged as collateral as part of derivative transactions. For additional information regarding pledged securities related to derivative transactions, see Note 4.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 31, 2015

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business and Basis of Presentation

Description of Business 

Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in the United States and Japan. The Company's insurance business is marketed and administered through American Family Life Assurance Company of Columbus (Aflac), which operates in the United States (Aflac U.S.) and as a branch in Japan (Aflac Japan). American Family Life Assurance Company of New York (Aflac New York) is a wholly owned subsidiary of Aflac. Most of Aflac's policies are individually underwritten and marketed through independent agents. Additionally, Aflac U.S. markets and administers group products through Continental American Insurance Company (CAIC), branded as Aflac Group Insurance. Our insurance operations in the United States and our branch in Japan service the two markets for our insurance business. Aflac Japan's revenues, including realized gains and losses on its investment portfolio, accounted for 70% and 75% of the Company's total revenues in the three-month periods ended March 31, 2015, and 2014, respectively. The percentage of the Company's total assets attributable to Aflac Japan was 82% at March 31, 2015 and December 31, 2014.

Basis of Presentation

We prepare our financial statements in accordance with U.S. generally accepted accounting principles (GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to GAAP issued by the FASB are derived from the FASB Accounting Standards Codification^TM (ASC). The preparation of financial statements in conformity with GAAP requires us to make estimates when recording transactions resulting from business operations based on currently available information. The most significant items on our balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments, deferred policy acquisition costs, liabilities for future policy benefits and unpaid policy claims, and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, mortality, morbidity, commission and other acquisition expenses, and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates will be revised and reflected in operating results. Although some variability is inherent in these estimates, we believe the amounts provided are adequate.

The unaudited consolidated financial statements include the accounts of the Parent Company, its subsidiaries and those entities required to be consolidated under applicable accounting standards. All material intercompany accounts and transactions have been eliminated.

In the opinion of management, the accompanying unaudited consolidated financial statements of the Company contain all adjustments, consisting of normal recurring accruals, which are necessary to fairly present the consolidated balance sheets as of March 31, 2015 and December 31, 2014, the consolidated statements of earnings, comprehensive income (loss), shareholder's equity and cash flows for the three-month periods ended March 31, 2015 and 2014. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, these financial statements should be read in conjunction with the financial statements and notes thereto included in our annual report to shareholders for the year ended December 31, 2014.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Income Statement - Extraordinary and Unusual Items - Simplifying income statement presentation by eliminating the concept of extraordinary items: In January 2015, the FASB issued updated guidance that eliminates from GAAP the concept of extraordinary items. Although the amendments will eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The amendments in this updated guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We adopted this guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations.

Transfers and Servicing, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures: In June 2014, the FASB issued updated guidance for repurchase agreement and security lending transactions to change the accounting for repurchase-to-maturity transactions and linked repurchase financings to be accounted for as secured borrowings, consistent with the accounting for other repurchase agreements. The amendments also require new disclosures to increase transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. We adopted accounting changes for the new guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations. However, the disclosures in the new guidance are required and will be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015.

Description of Accounting Pronouncements Pending Adoption

Accounting Pronouncements Pending Adoption

Interest - Imputation of Interest - Simplifying the presentation of debt issuance costs: In April 2015, FASB issued updated guidance to simplify presentation of debt issuance costs. The updated guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. The amendment is effective for annual periods and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Consolidation - Amendments to the consolidation analysis: In February 2015, the FASB issued updated guidance that affect evaluation of whether limited partnerships and similar legal entities (limited liability corporations and securitization structures, etc.) are variable interest entities (VIEs), evaluation of whether fees paid to a decision maker or a service provider are a variable interest, and evaluation of the effect of fee arrangements and the effect of related parties on the determination of the primary beneficiary under the VIE model for consolidation. The updated guidance eliminates the presumption that a general partner should consolidate a limited partnership. Limited partnership and similar legal entities that provide partners with either substantive kick-out rights or substantive participating rights (representing the partners’ controlling financial interest in the entity) over the general partner will now be evaluated under the voting interest model rather than the VIE model for consolidation. In regard to the fees paid to a decision maker or a service provider, the updated guidance eliminates three of the six criteria that an entity’s decision makers or service providers must meet for them to conclude that the fees do not represent a variable interest in that entity and, thus, should be excluded from the assessment for determining the primary beneficiary. Finally, in situations where no single party has a controlling financial interest in a VIE, the related party relationships under common control should be considered in their entirety in determining whether that common control group has a controlling financial interest in the VIE. However, if substantially all of the activities of the VIE are conducted on behalf of a single variable interest holder (excluding the decision maker) in a related party group that has the characteristics of a primary beneficiary, that single variable interest holder must consolidate the VIE as the primary beneficiary. The amendments in the updated guidance are effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017. Early application is permitted, including adoption in an interim period. We are evaluating whether the adoption of this guidance will have an impact on our financial position, results of operations or disclosures.

Derivatives and Hedging - Determining whether the host contract in a hybrid financial instrument issued in the form of a share is more akin to debt or equity: In November 2014, the FASB issued guidance to clarify how to evaluate the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. The guidance also clarifies that an entity should assess the substance of the relevant terms and features when considering how to weight those terms and features. The guidance is effective for annual periods and interim periods beginning after December 15, 2015. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Presentation of Financial Statements - Going Concern - Disclosure of uncertainties about an entity’s ability to continue as a going concern: In August 2014, the FASB issued this amendment that provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendment is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Compensation - Stock Compensation - Accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period: In June 2014, the FASB issued this amendment that provides guidance on certain share-based payment awards that require a specific performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.

Revenue from contracts with customers: In May 2014, the FASB issued updated guidance that affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.
