Review by Independent Registered Public Accounting Firm

The March 31, 2012, and 2011, 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, 2012, and the related consolidated statements of earnings, comprehensive income (loss), shareholders' equity and cash flows for the three-month periods ended March 31, 2012 and 2011. These consolidated financial statements are the responsibility of the Company's management.

We conducted our reviews 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 reviews, 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, 2011, and the related consolidated statements of earnings, shareholders' equity, cash flows and comprehensive income (loss) for the year then ended (not presented herein); and in our report dated February 24, 2012, we expressed an unqualified opinion on those consolidated financial statements. Our report refers to a change in the method of evaluating the consolidation of variable interest entities (VIEs) and qualified special purpose entities (QSPEs) in 2010 and a change in the method of evaluating other-than-temporary impairments of debt securities in 2009. As described in Note 1, on January 1, 2012, the Company adopted amended accounting guidance on accounting for costs associated with acquiring or renewing insurance contracts on a retrospective basis resulting in a revision of the December 31, 2011, consolidated balance sheet. We have not audited and reported on the revised balance sheet reflecting the adoption of this new guidance.

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). 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 77% and 74% of the Company's total revenues in the three-month periods ended March 31, 2012, and 2011, respectively. The percentage of the Company's total assets attributable to Aflac Japan was 87% at March 31, 2012, and December 31, 2011.

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 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, 2012, and December 31, 2011, and the consolidated statements of earnings, comprehensive income (loss), shareholders' equity and cash flows for the three-month periods ended March 31, 2012, and 2011. 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, 2011.

Significant Accounting Policies

We have revised the accounting policy for deferred policy acquisition costs as a result of the adoption of amended accounting guidance effective January 1, 2012, and we have updated the accounting policy for income taxes. All other categories of significant accounting policies remain unchanged from our annual report to shareholders for the year ended December 31, 2011.

Deferred Policy Acquisition Costs: Certain direct and incremental costs of acquiring new business are deferred and amortized with interest over the premium payment periods in proportion to the ratio of annual premium income to total anticipated premium income. Anticipated premium income is estimated by using the same mortality, persistency and interest assumptions used in computing liabilities for future policy benefits. In this manner, the related acquisition expenses are matched with revenues. Deferred costs include the excess of current-year commissions over ultimate renewal-year commissions and certain incremental direct policy issue, underwriting and sales expenses. All of these incremental costs are directly related to successful policy acquisition.

9

For some products, policyholders can elect to modify product benefits, features, rights or coverages by exchanging a contract for a new contract or by amendment, endorsement, or rider to a contract, or by the election of a feature or coverage within a contract. These transactions are known as internal replacements. For internal replacement transactions where the resulting contract is substantially unchanged, the policy is accounted for as a continuation of the replaced contract. Unamortized deferred acquisition costs from the original policy continue to be amortized over the expected life of the new policy, and the costs of replacing the policy are accounted for as policy maintenance costs and expensed as incurred. Internal replacement transactions that result in a policy that is not substantially unchanged are accounted for as an extinguishment of the original policy and the issuance of a new policy. Unamortized deferred acquisition costs on the original policy that was replaced are immediately expensed, and the costs of acquiring the new policy are capitalized and amortized in accordance with our accounting policies for deferred acquisition costs.

Income Taxes:Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing our income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which we expect the temporary differences to reverse. We record deferred tax assets for tax positions taken based on our assessment of whether the tax position is more likely than not to be sustained upon examination by taxing authorities. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized.

As discussed in the Translation of Foreign Currencies section in Note 1 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2011, Aflac Japan maintains a dollar-denominated investment portfolio on behalf of Aflac U.S. While there are no translation effects to record in other comprehensive income, the deferred tax expense or benefit associated with foreign exchange gains or losses on the portfolio is recognized in other comprehensive income until the securities mature or are sold. Total income tax expense (benefit) related to items of other comprehensive income (loss) included tax expense of $157 million and $51 million during the three-month periods ended March 31, 2012 and 2011, respectively, for this dollar-denominated portfolio. Excluding these amounts from total taxes on other comprehensive income would result in an effective income tax rate on pretax other comprehensive income (loss) of 44.5% and 32.4% in the three-month periods ended March 31, 2012 and 2011, respectively.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Presentation of comprehensive income: In June 2011, the FASB issued guidance to amend the presentation of comprehensive income.The amendment requires that all non-owner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. We adopted this guidance as of January 1, 2012 and elected the option to report comprehensive income in two separate but consecutive statements. The adoption of this guidance did not have an impact on our financial position or results of operations. The amendment also requires reclassification adjustments for items that are reclassified from other comprehensive income to net income to be presented in the statements where the components of net income and the components of other comprehensive income are presented; however, in December 2011, the FASB issued guidance to temporarily defer the effective date of this additional requirement.

Fair value measurements and disclosures: In May 2011, the FASB issued guidance to amend the fair value measurement and disclosure requirements. Most of the amendments are clarifications of the FASB's intent about the application of existing fair value measurement and disclosure requirements. Other amendments change a particular principle or requirement for measuring fair value or disclosing information about fair value measurements. The new fair value measurement disclosures include additional quantitative and qualitative disclosures for Level 3 measurements, including a qualitative sensitivity analysis of fair value to changes in unobservable inputs, and categorization by fair value hierarchy level for items for which the fair value is only disclosed. We adopted this guidance as of January 1, 2012. The adoption of this guidance impacted our financial statement disclosures, but it did not affect our financial position or results of operations.

Accounting for costs associated with acquiring or renewing insurance contracts: In October 2010, the FASB issued amended accounting guidance on accounting for costs associated with acquiring or renewing insurance contracts. Under the previous guidance, costs that varied with and were primarily related to the acquisition of a policy were

10

deferrable. Under the amended guidance, only incremental direct costs associated with the successful acquisition of a new or renewal contract may be capitalized, and direct-response advertising costs may be capitalized only if they meet certain criteria. This guidance is effective on a prospective or retrospective basis for interim and annual periods beginning after December 15, 2011. We retrospectively adopted this guidance as of January 1, 2012. The retrospective adoption of this accounting standard resulted in an after-tax cumulative reduction to retained earnings of $408 million and an after-tax cumulative reduction to unrealized foreign currency translation gains in accumulated other comprehensive income of $108 million, resulting in a total reduction to shareholders' equity of $516 million as of December 31, 2010. The adoption of this accounting standard had an immaterial impact on net income in 2011 and for all preceding years.

Recent accounting guidance not discussed above is not applicable or did not have an 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, 2011.

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 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 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) and nonrecurring items. 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 debt securities, perpetual securities and equity securities are described in Note 5.

During the first three months of 2012, we reclassified one investment from the held-to-maturity portfolio to the available-for-sale portfolio as a result of a significant decline in the issuer's credit worthiness. At the time of transfer, the security had an amortized cost of $122 million and an unrealized loss of $23 million. This investment was issued by Energias de Portugal SA (EDP), an integrated electric utility domiciled in Portugal.

During the first three months of 2011, we reclassified eight investments from the held-to-maturity portfolio to the available-for-sale portfolio as a result of a significant decline in the issuers' credit worthiness.  At the time of the transfer, the securities had an aggregate amortized cost of $1.6 billion and an aggregate unrealized loss of $270 million.  The securities transferred included our investments in the Republic of Tunisia that had an aggregate amortized cost of $769 million and four securities associated with financial institutions in Portugal and Ireland with an aggregate amortized cost of $631 million.  The investments from the financial institutions in Portugal were subsequently sold by the end of the third quarter of 2011.

Contractual and Economic Maturities

The contractual maturities of our investments in fixed maturities at March 31, 2012, were as follows:

At March 31, 2012, the Parent Company had a portfolio of investment-grade available-for-sale fixed-maturity securities totaling $120 million at amortized cost and $136 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 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 of 125 to more than 300 basis points above an appropriate market index, generally by the 25th year after issuance, thereby creating an economic maturity date. The economic maturities of our investments in perpetual securities, which were all reported as available for sale at March 31, 2012, were as follows:

Investment Concentrations

Our investment discipline begins with a top-down approach for each investment opportunity we consider. Consistent with that approach, we first approve each country in which we invest. In our approach to sovereign analysis, we consider the political, legal and financial context of the sovereign entity in which an issuer is domiciled and operates. Next we approve the issuer's industry sector, considering such factors as the stability of results and the importance of the sector to the overall economy. Specific credit names within approved countries and industry sectors are evaluated for their market position and specific strengths and potential weaknesses. Structures in which we invest are chosen for specific portfolio management purposes, including asset/liability management, portfolio diversification and net investment income.

16

Banks and Financial Institutions

After Japan government bonds (JGBs), our second largest investment concentration as of March 31, 2012, 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. We achieve some degree of diversification in the bank and financial institution sector through a geographically diverse universe of credit exposures. Within this sector, the more significant concentration of our credit risk by geographic region or country of issuer at March 31, 2012, based on amortized cost, was: Europe, excluding the United Kingdom (35%); United States (23%); United Kingdom (9%); Japan (8%); and other (25%).

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

Derisking

During the three-month period ended March 31, 2012, we continued our efforts which began in the first quarter of 2011 of pursuing strategic investment activities to lower the risk profile of our investment portfolio. Our primary focus during the first quarter of 2012 was on reducing our exposure to perpetual and other subordinated securities of European issuers, particularly in the financial sector. See further details in the Realized Investment Gains and Losses section below.

During the three-month period ended March 31, 2012, sales and redemptions of securities generated a net realized investment gain. This net gain primarily resulted from both the redemption of a previously impaired perpetual security and sales related to our implemented plan to reduce the risk exposure in our investment portfolio (see the Investment Concentrations section above for more information). The other-than-temporary losses that we recognized were largely composed of impairments for two Tier I securities that were sold subsequent to the end of the quarter.

During the three-month period ended March 31, 2011, we recognized other-than-temporary impairment losses and realized investment losses from the sale of securities, primarily a result of an implemented plan to reduce the risk exposure in our investment portfolio coupled with the continued decline in the credit worthiness of certain issuers.

Other-than-temporary Impairment

The fair value of our debt and perpetual security investments fluctuates based on changes in credit spreads in the global financial markets. Credit spreads are most impacted by market rates of interest, the general and specific credit environment and global market liquidity. We believe that fluctuations in the fair value of our investment securities related to changes in credit spreads have little bearing on whether our investment is ultimately recoverable. Generally, we consider such declines in fair value 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. In this event, we consider such a decline in the investment's fair value, to the extent below the investment's cost or amortized cost, to be an other-than-temporary impairment of the investment and write the investment down to its fair value.

In addition to the usual investment risk associated with a debt instrument, our perpetual security holdings may be

18

subject to the 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 build capital. In addition to 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 impair the fair value of the securities and increase our regulatory capital requirements. We take factors such as these into account 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, decisions to reposition our security portfolio and sales of securities to meet cash flow needs. 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 matching 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 liquidating any of our investments prior to their maturity. In years prior to 2011, provided that our credit review process resulted in a conclusion that we would collect all of our cash flows and recover our investment in an issuer and the investment was within our investment risk exposure guidelines, we generally did not sell investments prior to their maturity. However, starting in the fourth quarter of 2011, we determined that certain securities were no longer within our investment risk exposure guidelines and have started to reposition our security portfolio in an effort to enhance diversification and our credit profile by reducing our risk exposure through opportunistic investment transactions.

Analysis of Securities in Unrealized Loss Positions

The unrealized losses on our investments have been primarily related to changes in risk-free interest rates, foreign exchange rates or the general widening of credit spreads rather than specific issuer credit-related events. In addition, because we do not intend to sell and do not believe it is likely that we will be required to sell these investments before a recovery of fair value to amortized cost, we do not consider any of these investments to be other-than-temporarily impaired as of and for the three-month period ended March 31, 2012. The following summarizes our evaluation of investment categories with significant unrealized losses and securities that were rated below investment grade as of March 31, 2012.

Public Utilities

As of March 31, 2012, 69% of the unrealized losses on investments in the public utilities sector was related to investments that were investment grade, compared with 77% at December 31, 2011. For any credit-related declines in fair value, we perform a more focused review of the related issuer's credit ratings, financial statements and other available financial data, timeliness of payment, competitive environment and any other significant data related to the issuer. From those reviews, we evaluate the issuer's continued ability to service our investment. We have determined that the majority of the unrealized losses on the investments in the public utilities sector was caused by a decline in creditworthiness of a couple issuers in this sector. Also impacting the unrealized losses in the public utilities sector was widening credit spreads.

Based on our credit analysis, we believe that the issuers of our investments in this sector have the ability to service their obligations to us.

Sovereign and Supranational

As of March 31, 2012, 94% of the unrealized losses on investment securities in the sovereign and supranational sector were related to investments that were investment grade, compared with 100% at December 31, 2011. For any credit-related declines in fair value, we perform a more focused review of the related issuers' credit ratings, financial statements and other available financial data, timeliness of payment, gross domestic product growth projections, balance of payments, foreign currency reserves, and any other significant data related to the issuers. From those reviews, we evaluate the issuers' continued ability to service our investments. We have determined that the majority of the unrealized losses on the investments in the sovereign and supranational sector was caused by a decline in creditworthiness of certain issuers in this sector. Also impacting the unrealized losses in the sovereign and supranational sector was widening credit spreads. Based on our credit analysis, we believe that the issuers of our investments in this sector have the ability to service their obligations to us.

Bank and Financial Institution Investments

Our efforts during 2011 and the three-month period ended March 31, 2012 to reduce risk in our investment portfolio included sales and impairments of certain investments in banks and financial institutions, with an emphasis on reducing our exposure to European financial institutions. The following table shows the composition of our investments in an unrealized loss position in the bank and financial institution sector by fixed-maturity securities and perpetual securities. The table reflects those securities in that sector that were in an unrealized loss position as a percentage of our total investment portfolio in an unrealized loss position and their respective unrealized losses as a percentage of total unrealized losses.

	March 31, 2012						December 31, 2011
	Percentage of Total Investments in an Unrealized Loss Position			Percentage of Total Unrealized Losses			Percentage of Total Investments in an Unrealized Loss Position			Percentage of Total Unrealized Losses
Fixed maturities		32	%		44	%		37	%		44	%
Perpetual securities:
Upper Tier II		4			5			4			6
Tier I		3			6			5			12
Total perpetual securities		7			11			9			18
Total		39	%		55	%		46	%		62	%

As of March 31, 2012, 85% of the $1.5 billion in unrealized losses on investments in the bank and financial institution sector, including perpetual securities, was related to investments that were investment grade, compared with 80% at December 31, 2011. Of the $12.0 billion in total investments, at fair value, in this sector in an unrealized loss position at March 31, 2012, only $629 million($227 million in unrealized losses) was below investment grade. Three issuers of investments comprised nearly 99% of the $227 million unrealized loss. The remaining unrealized loss comprised one investment with an unrealized loss of less than $3 million .

We conduct our own independent credit analysis for investments in the bank and financial institution sector. Our assessment includes analysis of financial information, as well as consultation with the issuers from time to time. Based on our credit analysis, we have determined that the majority of the unrealized losses on the investments in this sector was caused by widening credit spreads, the downturn in the global economic environment and, to a lesser extent, changes in foreign exchange rates. Unrealized gains or losses related to prevailing interest rate environments are impacted by the remaining time to maturity of an investment. Assuming no credit-related factors develop, as investments near maturity, the unrealized gains or losses can be expected to diminish. Based on our credit analysis, we believe that the issuers of our investments in this sector have the ability to service their obligations to us.

Other Corporate Investments

As of March 31, 2012, 75% of the unrealized losses on investments in the other corporate sector was related to

22

investments that were investment grade, compared with 73% at December 31, 2011. For any credit-related declines in fair value, we perform a more focused review of the related issuer's credit ratings, financial statements and other available financial data, timeliness of payment, competitive environment and any other significant data related to the issuer. From that review, we evaluate the issuer's continued ability to service our investment. We have determined that the majority of the unrealized losses on the investments in the other corporate sector were caused by widening credit spreads. Also impacting the unrealized losses in this sector is the decline in creditworthiness of certain issuers in the other corporate sector. Based on our credit analysis, we believe that the issuers of our investments in this sector have the ability to service their obligations to us.

Perpetual Securities

As of March 31, 2012, 91% of the unrealized losses on investments in perpetual securities was related to investments that were investment grade, compared with 73% at December 31, 2011. 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:

Perpetual Securities

An aspect of our efforts during 2011 and the three-month period ended March 31, 2012 to reduce risk in our investment portfolio included sales and impairments of certain investments in perpetual securities. With the exception of the Icelandic bank securities that we completely impaired in 2008, none of the perpetual securities we own were in default on interest and principal payments at March 31, 2012. During the second quarter of 2011, we wrote off accrued interest income and stopped accruing further interest income for the Dexia S.A. Upper Tier II perpetual securities, which had a deferred coupon and were impaired during that quarter, and we recognized additional impairments on those securities in the third and fourth quarters of 2011. We collected the deferred coupon upon the sale of those securities as part of our derisking investment activities in the first quarter of 2012. Based on amortized cost as of March 31, 2012, the geographic breakdown of our perpetual securities by issuer was as follows: European countries, excluding the United Kingdom, (69%); the United Kingdom (11%); Japan (12%); and other (8%). To determine any credit-related declines in fair value, we perform a more focused review of the related issuer's credit ratings, financial statements and other available financial data, timeliness of payment, competitive environment and any other significant data related to the issuer. From that review, we evaluate the issuer's continued ability to service our investment.

We have determined that the majority of our unrealized losses in the perpetual security category was principally due to widening credit spreads, largely as the result of the contraction of liquidity in the capital markets. Based on our reviews,

23

we concluded that the ability of the issuers to service our investments has not been compromised by these factors. Unrealized gains or losses related to prevailing interest rate environments are impacted by the remaining time to maturity of an investment. Assuming no credit-related factors develop, as the investments near economic maturity, the unrealized gains or losses can be expected to diminish. Based on our credit analyses, we believe that the issuers of our investments in this sector have the ability to service their obligations to us.

Variable Interest Entities (VIEs)

The following table details our investments in VIEs.

Investments in Variable Interest Entities

	March 31, 2012				December 31, 2011
(In millions)	Amortized Cost		Fair Value		Amortized Cost		Fair Value
VIEs:
VIEs consolidated	$	6,545	$	6,940	$	6,997	$	7,206
VIEs not consolidated	12,795		12,832		13,753		13,714
Total VIEs	$	19,340	$	19,772	$	20,750	$	20,920

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 have not been nor are we 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

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 interest rate, 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 a unit trust structure that we began investing in during the second quarter of 2011, 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

24

underlying credit default swaps. We currently own only senior CDO tranches. Based on our statistical analysis models, each of these VIEs can sustain a reasonable number of defaults in the underlying reference corporate entities in the CDSs with no loss to our investment.

VIEs-Not Consolidated

The VIEs that we are not required to consolidate are investments that are limited to loans in the form of debt obligations from the VIEs that are irrevocably and unconditionally guaranteed by their corporate parents. These VIEs are the primary financing vehicle 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 are comprised of securities from 161 separate issuers which have an average credit rating of A.

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

(In millions)	March 31, 2012		December 31, 2011
Security loans outstanding, fair value	$	188	$	812
Cash collateral on loaned securities	193		838

4.  DERIVATIVE INSTRUMENTS

We do not use derivative financial instruments for trading purposes, nor do we engage in leveraged derivative transactions. The majority of our freestanding derivatives are interest rate, foreign currency and credit default swaps that are associated with investments in special-purpose entities, including VIEs where we are the primary beneficiary. The remaining derivatives are the interest rate swap associated with our variable interest rate yen-denominated debt and cross-currency interest rate swaps associated with our senior notes due in February 2017 and February 2022.

Derivative Types

Interest rate and credit default 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. Generally, no cash or principal payments are exchanged at the inception of the contract. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. 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.

Credit default swaps are used to assume credit risk related to an individual security or an index. These contracts entitle the consolidated VIE to receive a periodic fee in exchange for an obligation to compensate the derivative counterparty should the referenced security issuers experience a credit event, as defined in the contract. The consolidated VIE is also exposed to credit risk due to embedded derivatives associated with credit-linked notes.

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. 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 convert certain of our dollar-denominated principal and interest senior note obligations into yen-denominated obligations.

Credit Risk Assumed through Derivatives

For the interest rate, foreign currency, and credit default swaps associated with our VIE investments for which we are

25

the primary beneficiary, we bear the risk of foreign exchange or interest rate loss due to counterparty default even though we are not a direct counterparty to those contracts. We are exposed to credit risk in the event of nonperformance by counterparties to the cross-currency swaps related to our senior notes due in February 2017 and 2022 and the interest rate swap on our variable interest rate yen-denominated Samurai notes. The risk of counterparty default for both the VIE and senior note swaps is mitigated by collateral posting requirements the counterparty must meet. The counterparties to these swap agreements are financial institutions with the following credit ratings.

	March 31, 2012							December 31, 2011
	Fair Value				Notional Amount			Fair Value				Notional Amount
(In millions)	of Swaps				of Swaps			of Swaps				of Swaps
Counterparty credit rating:
AA		$	14			$	272		$	0			$	0
A		(124		)		5,756			(156		)		5,491
Total		$	(110	)		$	6,028		$	(156	)		$	5,491

Certain of our consolidated VIEs have credit default swap contracts that require them to assume credit risk from an asset pool. Those consolidated VIEs will receive periodic payments based on an agreed upon rate and notional amount and will only make a payment by delivery of associated collateral, which consists of highly rated asset-backed securities, if there is a credit event. A credit event payment will typically be equal to the notional value of the swap contract less the value of the referenced obligations. A credit event is generally defined as a default on contractually obligated interest or principal payments or bankruptcy of the referenced entity. The diversified portfolios of corporate issuers are established within sector concentration limits.

The following tables present the maximum potential risk, fair value, weighted-average years to maturity, and underlying referenced credit obligation type for credit default swaps within consolidated VIE structures.

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.

Hedging

Derivative Hedges

Certain of our consolidated VIEs have interest rate and/or 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 14 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”).

We have an interest rate swap agreement related to our 5.5 billion yen variable interest rate Samurai notes that we issued in July 2011 (see Note 6). By entering into this contract, we swapped the variable interest rate to a fixed interest rate of 1.475%. We have designated this interest rate swap as a hedge of the variability in our interest cash flows associated with the variable interest rate Samurai notes. The notional amount and terms of the swap match the principal amount and terms of the variable interest rate Samurai notes, and the swap had no value at inception. Changes in the fair value of the swap contract are recorded in other comprehensive income so long as the hedge is deemed effective. Should any portion of the hedge be deemed ineffective, that value would be reported in net earnings.

Hedge Documentation and Effectiveness Testing

To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated changes in cash flow of the hedged item. At hedge inception, 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. The documentation process includes linking derivatives that are designated as cash flow hedges to specific 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 changes in cash flows of hedged items. Hedge effectiveness is assessed using qualitative and quantitative methods. Qualitative methods may include the comparison of critical terms of the derivative to the hedged item. Quantitative methods include regression or other statistical analysis of changes in cash flows associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships 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 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 as a component of realized investment gains (losses). All components of each derivative's gain or loss were included in the assessment of hedge effectiveness.

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 cash flows 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, including those where the derivative is sold, terminated or exercised, amounts previously deferred in other comprehensive income are reclassified into earnings when earnings are impacted by the cash flow of the hedged item.

Cash Flow Hedges

The following table presents the components of the gain or loss on derivatives that qualified as cash flow hedges.

28

Derivatives in Cash Flow Hedging Relationships

(In millions)	Gain (Loss) Recognized in Other Comprehensive Income on Derivative (Effective Portion)				Realized Investment Gains (Losses) Recognized in Income on Derivative (Ineffective Portion)
Three Months Ended March 31, 2012:
Interest rate swaps		$	0			$	0
Foreign currency swaps		(12		)		0
Total		$	(12	)		$	0
Three Months Ended March 31, 2011:
Interest rate swaps		$	1			$	0
Foreign currency swaps		(56		)		(4		)
Total		$	(55	)		$	(4	)

In the third quarter of 2011, we de-designated certain of the foreign currency swaps with notional values totaling $500 million used in cash flow hedging strategies as a result of determining that these swaps would no longer be highly effective in offsetting the cash flows of the hedged item. As a result, the net gain recorded in accumulated other comprehensive income for these swaps that are no longer eligible for hedge accounting is being amortized into earnings over the expected life of the respective hedged item. The amount amortized from accumulated other comprehensive income into earnings related to these swaps was immaterial in 2011. There was no gain or loss reclassified from accumulated other comprehensive income into earnings related to our designated cash flow hedges for the three-month periods ended March 31, 2012 and 2011. As of March 31, 2012, deferred net gains on derivative instruments recorded in accumulated other comprehensive income that are expected to be reclassified to earnings during the next twelve months are immaterial.

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 as realized investment gains (losses).

We have cross-currency swap agreements related to our $400 million senior notes due February 2017 and our $350 million senior notes due February 2022 (see Note 6). The notional amounts and terms of the swaps match the principal amount and terms of the senior notes. We entered into these cross-currency swaps to reduce interest expense by converting the dollar-denominated principal and interest on the senior notes we issued into yen-denominated obligations. By entering into these cross-currency swaps, we economically converted our $400 million liability into a 30.9 billion yen liability and reduced the interest rate on this debt from 2.65% in dollars to 1.22% in yen, and we economically converted our $350 million liability into a 27.0 billion yen liability and reduced the interest rate on this debt from 4.00% in dollars to 2.07% in yen.

The following table presents the gain or loss recognized in income on non-qualifying strategies.

Non-qualifying Strategies

Gain (Loss) Recognized within Realized Investment Gains (Losses)

	Three Months Ended March 31,
(In millions)	2012				2011
Interest rate swaps		$	(3	)		$	(5	)
Foreign currency swaps		50				(29		)
Credit default swaps		33				5
Other		0				3
Total		$	80			$	(26	)

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 income or perpetual securities associated with these swaps is recorded through other comprehensive income.

29

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 taken the following courses of action. First, Aflac Japan maintains an investment portfolio of dollar-denominated securities on behalf of Aflac U.S., which serves as an economic currency hedge of a portion of our investment in Aflac Japan. The functional currency for these investments is the U.S. dollar. The related investment income and realized/unrealized investment gains and losses are also denominated in U.S. dollars. The foreign exchange gains and losses related to this portfolio are taxable in Japan and the U.S. when the securities mature or are sold. Until maturity or sale, deferred tax expense or benefit associated with the foreign exchange gains or losses are recognized in other comprehensive income.

Second, we have designated a majority of the Parent Company's yen-denominated liabilities (Samurai and Uridashi notes and yen-denominated loans - see Note 6) as nonderivative hedges of the foreign currency exposure of our investment in Aflac Japan. Our net investment hedge was effective during the three-month periods ended March 31, 2012, and 2011.

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

Our DCF pricing model incorporates an option adjusted spread and utilizes various market inputs we obtain from both active and inactive markets. The estimated fair values developed by the DCF pricing model is most sensitive to prevailing credit spreads, the level of interest rates (yields) and interest rate volatility. Credit spreads are derived using a bond index to create a credit spread matrix which takes into account the current credit spread, ratings and remaining time to maturity, and subordination levels for securities that are included in the bond index. Our DCF pricing model is based on a widely used global bond index that is comprised of investments in active markets. The index provides a broad-based measure of the global fixed-income bond market. This index covers bonds issued by European and American issuers, which account for the majority of bonds that we hold. We validate the reliability of the DCF pricing model periodically by using the model to price investments for which there are quoted market prices from active and inactive markets or, in the alternative, are quoted by our custodian for the same or similar securities.

The pricing data and market quotes we obtain from outside sources 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. Based on that analysis, the valuation is confirmed or revised.

The fair values of our publicly issued notes payable were obtained from a limited number of independent brokers, and the fair values of our yen-denominated loans approximate their carrying values. The fair value of the obligation to the Japanese policyholder protection corporation is our estimated share of the industry's obligation calculated on a pro rata basis by projecting our percentage of the industry's premiums and reserves and applying that percentage to the total industry obligation payable in future years.

The carrying amounts for cash and cash equivalents, 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. Consequently, such instruments are not included in the above table. The preceding table also excludes liabilities for future policy benefits and unpaid policy claims as these liabilities are not financial instruments as defined by GAAP.

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.

As of March 31, 2012, approximately 51% of the fair value, or 77% of the number of holdings, of our available-for-sale fixed income and perpetual investments classified as Level 2 and 3% of the fair value, or 7% of the number of holdings, of our held-to-maturity fixed income investments classified as Level 2 are valued by obtaining quoted market prices from our investment custodian. The custodian obtains price quotes from various third party pricing services that estimate fair values based on observable market transactions for similar investments in active markets, market transactions for the same investments in inactive markets, or other observable market data where available. The fair value of approximately 42% of our Level 2 available-for-sale fixed income and perpetual investments, or 10% of the number of Level 2 available-for-sale holdings, and 95% of our Level 2 held-to-maturity fixed income investments, or 85% of the number of Level 2 held-to-maturity holdings, are determined using our DCF pricing model. The significant valuation inputs to the DCF model are obtained from, or corroborated by, observable market sources from both active and inactive markets. For the remaining 7% of Level 2 available-for-sale investment valuations, or 13% of the number of Level 2 available-for-sale holdings, and the remaining 2% of Level 2 held-to-maturity investment valuations, or 8% of the number of Level 2 held-to-maturity holdings, that are not provided by our custodian and are not priced using the DCF pricing model, we obtain quotes from other pricing services that estimate fair values based on observable market transactions for similar investments in active markets, market transactions for the same investment in inactive markets, or other observable market data where available.

Due to our reliance on third-party pricing services to provide valuations on 51% of our Level 2 available-for-sale portfolio and 3% of our Level 2 held-to-maturity portfolio, we regularly discuss and review pricing methodologies with the investment custodian. We also review the custodians' Service Organization Control (SOC 1) report for the period covering the current year to gain satisfaction with the controls and control environment of the custodian.

For securities in Level 2 that are below investment grade or have split ratings where the valuation calculated by our DCF model does not conform to current market conditions, a CDS spread is used in lieu of the index spread discussed above. The CDS is chosen based on an average of spreads of issues with the same issuer, rating and subordination.

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 value of the foreign currency swaps associated with our senior notes is based on the amount we would expect to receive or pay to terminate the swaps. The determination of the fair value of the swaps 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. Prior to the third quarter of 2011, these derivative instruments were reported in Level 2 of the fair value hierarchy, except CDSs and certain foreign currency swaps which were classified as Level 3. The interest rate and certain foreign currency derivative instruments previously classified as Level 2 were priced by broker quotations. In the third quarter of 2011, we changed from receiving valuations from brokers to receiving valuations from a third party pricing vendor for our 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 have been classified as Level 3 of the fair value hierarchy as of September 30, 2011 and thereafter.

The fixed maturities classified as Level 3 consist of securities for which there are limited or no observable valuation inputs. 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. The significant valuation inputs that are used in the valuation process for the below-investment-grade and private placement investments classified as Level 3 include 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.

The equity securities classified in Level 3 are related to investments in Japanese businesses, each of which are insignificant and in the aggregate are immaterial. Because fair values for these investments are not readily available, we

35

carry them at their original cost. We review each of these investments periodically and, in the event we determine that any are other-than-temporarily impaired, we write them down to their estimated fair value at that time.

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 value of the obligation to the Japanese policyholder protection corporation classified as Level 3 is our estimated share of the industry's obligation calculated on a pro rata basis by projecting our percentage of the industry's premiums and reserves and applying that percentage to the total industry obligation payable in future years. We consider our inputs for this valuation to be unobservable.

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

Transfers into and/or out of Level 3 are attributable to a change in the observability of inputs. Transfers into and/or out of any fair value hierarchy level are assumed to occur at the balance sheet date. There were no transfers between Level 1 and 2 for the three-month periods ended March 31, 2012 and 2011.

Fair Value Sensitivity

DCF Sensitivity

Our DCF pricing model utilizes various market inputs we obtain from both active and inactive markets. The estimated fair values developed by the DCF pricing models are most sensitive to prevailing credit spreads, the level of interest rates (yields), and, for our callable securities, interest rate volatility. Management believes that under normal market conditions, a movement of 50 basis points (bps) in interest rates and credit spreads and 50 percent in interest rate volatility would be sufficiently reasonable stresses to illustrate the sensitivity of valuations to these risk factors. Therefore, we selected these magnitudes of movement and provided both upward and downward movements in these key assumptions used to estimate fair value. Since the changes in fair value are relatively linear, readers of these financial statements can make their own judgments as to the movement in interest rates and the change in fair value based upon this data. The following scenarios provide a view of the sensitivity of our securities priced by our DCF pricing model.

The fair values of our available-for-sale fixed-maturity and perpetual securities valued by our DCF pricing model totaled $18.2 billion at March 31, 2012. The estimated effect of potential changes in interest rates, credit spreads and interest rate volatility on these fair values as of such date is as follows:

	Interest Rates						Credit Spreads						Interest Rate Volatility
Factor Change		Change in fair value   (in millions)				Factor change		Change in fair value   (in millions)				Factor change		Change in fair value   (in millions)
	+50 bps		$	(978	)		+50 bps		$	(975	)		+50 %		$	(36	)
	-50 bps		999				-50 bps		1,011				-50 %		1

The fair values of our held-to-maturity fixed-maturity securities valued by our DCF pricing model totaled $23.9 billion at March 31, 2012. The estimated effect of potential changes in interest rates, credit spreads and interest rate volatility on these fair values as of such date is as follows:

	Interest Rates						Credit Spreads						Interest Rate Volatility
Factor Change		Change in fair value   (in millions)				Factor change		Change in fair value   (in millions)				Factor change		Change in fair value   (in millions)
	+50 bps		$	(1,488	)		+50 bps		$	(1,379	)		+50 %		$	(132	)

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. Listed below each discussion are the asset and derivative categories impacted by the respective input or valuation technique.

Annualized historical foreign exchange volatility

We own a portfolio of callable reverse dual-currency bonds (RDCs). RDCs are securities that have principal denominated in yen while paying U.S. dollar (USD) coupons. The significant unobservable input used for valuation is the historical foreign exchange volatility. The market standard approach is to use implied volatility to value options or instruments with optionality, because historical volatility may not represent current market participants' expectations about future volatility. Given the importance of this input to the overall valuation, use of historical volatility could result in a significant increase or decrease in fair value measurement.

• Public utilities, Other corporate, Sovereign and supranational, Banks/financial institutions

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.

• Equity 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 and are best estimates of value at that particular point in time.

• Mortgage- and asset-backed securities

• Banks/financial institutions

• Other Corporate

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 with fixed pay and receive legs. This increases the sensitivity of the swap 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 USD/JPY foreign exchange rate in this way. In cases where there is no final exchange foreign exchange receivable in JPY and we are paying JPY as interest payments, 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.

42

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.

• Foreign currency swaps

Base Correlations, CDS Spreads

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 names 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.

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.

⁽³⁾ $350 issuance net of a $1 underwriting discount that is being amortized over the life of the notes

In February 2012, the Parent Company issued two series of senior notes totaling $750 million through a U.S. public debt offering. The first series, which totaled $400 million, bears interest at a fixed rate of 2.65% per annum, payable semi-annually, and has a five-year maturity. The second series, which totaled $350 million, bears interest at a fixed rate of 4.00% per annum, payable semi-annually, and has a ten-year maturity. We have entered into cross-currency swaps to reduce interest expense by converting the dollar-denominated principal and interest on the senior notes we issued into yen-denominated obligations. By entering into these cross-currency swaps, we economically converted our $400 million liability into a 30.9 billion yen liability and reduced the interest rate on this debt from 2.65% in dollars to 1.22% in yen, and we economically converted our $350 million liability into a 27.0 billion yen liability and reduced the interest rate on this debt from 4.00% in dollars to 2.07% in yen.

We have no restrictive financial covenants related to our notes payable. We were in compliance with all of the covenants of our notes payable at March 31, 2012. No events of default or defaults occurred during the three-month period ended March 31, 2012.

For additional information, see Notes 4 and 8 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2011.

Outstanding share-based awards are excluded from the calculation of weighted-average shares used in the computation of basic earnings per share (EPS). The following table presents the approximate number of share-based awards to purchase shares, on a weighted-average basis, that were considered to be anti-dilutive and were excluded from the calculation of diluted earnings per share for the three-month periods ended March 31.

(In thousands)	2012	2011
Anti-dilutive share-based awards	5,457	2,592

Share Repurchase Program:During the first quarter of 2012, we did not repurchase any shares of our common stock in the open market. We repurchased 3.1 million shares of our common stock in the first quarter of 2011.

As of March 31, 2012, a remaining balance of 24.4 million shares of our common stock was available for purchase under a share repurchase authorization by our board of directors in 2008.

8.  SHARE-BASED COMPENSATION

As of March 31, 2012, 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 and generally vest after three 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 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. Generally, the awards vest based upon time-based conditions or time- and performance-based conditions. Performance-based vesting conditions generally include the attainment of goals related to Company financial performance. Effective March 14, 2012, the board of directors approved an amendment and restatement of the long-term incentive plan subject to approval by shareholders at the Company's annual shareholders' meeting on May 7, 2012. If approved, the amendments to the plan would, among other things, extend its expiration date

45

from 2014 to 2017, make clear that option strike prices can be set at the closing price on the date of grant (rather than only at the average high-low sales price), update the performance factors available for use under awards that are intended to qualify for favorable tax deduction treatment, and adjust the size of awards that may be granted to incumbent directors. There were no additional shares of common stock authorized for issuance under the amended and restated plan. As of March 31, 2012, approximately 14 million shares were available for future grants under the existing 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, 2012.

	Stock Option Shares (in thousands)	Weighted-Average Remaining Term (in years)	Aggregate Intrinsic Value (in millions)	Weighted-Average Exercise Price Per Share
Outstanding	14,452	5.0	$77	$43.49
Exercisable	12,102	4.3	74	42.48

We received cash from the exercise of stock options in the amount of $6 million during the first quarter of 2012, compared with $10 million in the first quarter of 2011. The tax benefit realized as a result of stock option exercises and restricted stock releases was $13 million in the first quarter of 2012, compared with $11 million in the first quarter of 2011.

As of March 31, 2012, total compensation cost not yet recognized in our financial statements related to restricted stock awards was $48 million, of which $24 million (734 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 2.1 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 11 of the Notes to the Consolidated Financial Statements included in our annual report to shareholders for the year ended December 31, 2011.

9. 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.

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. Substantially all of our U.S. employees may become eligible to receive other postretirement benefits if they retire at age 55 or older with at least 15 years of service or if they retire when their age plus service, in years, equals or exceeds 80. At retirement, an employee is given an opportunity to elect continuation of coverage under our medical plan until age 65.

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:

46

	Three Months Ended March 31,
	Pension Benefits												Other
	Japan						U.S.						Postretirement Benefits
(In millions)	2012			2011			2012			2011			2012		2011
Components of net periodic benefit cost:
Service cost	$	4		$	4		$	6		$	4		$	1	$	1
Interest cost	3			2			7			7			1		1
Expected return on plan assets	(1		)	(1		)	(4		)	(4		)	0		0
Amortization of net actuarial loss	1			1			2			1			0		0
Net periodic (benefit) cost	$	7		$	6		$	11		$	8		$	2	$	2

During the three months ended March 31, 2012, Aflac Japan contributed approximately $6 million (using the weighted-average yen/dollar exchange rate for the three-month period ending March 31, 2012) 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 13 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2011.

10.   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.

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 period from December 31, 2011, to March 31, 2012. 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, 2011. 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

Results for the first quarter of 2012 benefited from the stronger yen/dollar exchange rate. Total revenues rose 21.9% to $6.2 billion, compared with $5.1 billion in the first quarter of 2011. Net earnings were $785 million, or $1.68 per diluted share, compared with $389 million, or $.83 per diluted share, in the first quarter of 2011.

Results in the first quarter of 2012 included pretax net realized investment losses of $45 million ($29 million after-tax), compared with net realized investment losses of $579 million ($376 million after-tax) in the first quarter of 2011. Net investment losses in the first quarter of 2012 included $203 million ($132 million after-tax) of other-than-temporary impairment losses; $78 million of net gains ($51 million after-tax) from the sale or redemption of securities; and $80 million of net gains ($52 million after-tax) from valuing derivatives. Shareholders’ equity at March 31, 2012 included a net unrealized gain on investment securities (including derivatives) of $1.4 billion, compared with a net unrealized gain of $1.2 billion at December 31, 2011.

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 at which 96% of our assets and 81% of our liabilities are reported as of March 31, 2012, and thus has a direct effect on net earnings and shareholders’ equity. Subsequent experience or use of other assumptions could produce significantly different results.

See Note 1 of the Notes to the Consolidated Financial Statements for information on changes to the accounting policy for deferred policy acquisition costs, costs associated with acquiring or renewing insurance contracts. There have been no other changes in the items that we have identified as critical accounting estimates during the three months ended March 31, 2012. 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, 2011.

New Accounting Pronouncements

On January 1, 2012, we retrospectively adopted amended accounting guidance on accounting for costs associated with acquiring or renewing insurance contracts, or DAC. Under the previous guidance, we deferred costs that varied with and were primarily related to the acquisition of a policy. Under the amended accounting guidance, only incremental direct costs associated with the successful acquisition of new or renewal contracts may be capitalized, and direct-response advertising costs may be capitalized under certain conditions. As of December 31, 2010, approximately 70% of our unadjusted deferred acquisition cost balance was related to compensation paid to third parties for successful sales and was therefore still deferrable under the new rules. The remaining 30% of the deferred acquisition costs balance was evaluated for deferral under the amended accounting guidance. The retrospective adoption of this accounting standard resulted in an after-tax cumulative reduction to retained earnings of $408 million and an after-tax cumulative reduction to unrealized foreign currency translation gains in accumulated other comprehensive income of $108 million, resulting in a total reduction to shareholders' equity of $516 million as of December 31, 2010. The adoption of this accounting standard had an immaterial impact on net income in 2011 and for all preceding years.

For additional 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 table is a presentation of items impacting net earnings and net earnings per diluted share.

Prior-year amounts have been adjusted for the adoption of accounting guidance on January 1, 2012 related to deferred policy acquisition costs.

Realized Investment Gains and Losses

Our investment strategy is to invest in fixed-income securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s profitability. This investment strategy aligns our assets with our liability structure, which our assets support. 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 maintenance 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, 2012, we realized pretax investment gains, net of losses, of $78 million ($51 million after-tax) from sales and redemptions of securities. These gains primarily resulted from both the redemption of a previously impaired perpetual security and sales related to our implemented plan to reduce the risk exposure in our investment portfolio. We realized pretax investment losses of $203 million ($132 million after-tax) as a result of the recognition of other-than-temporary impairment losses on certain securities. These losses primarily resulted from impairments on two Tier I securities that were sold subsequent to the end of the quarter.

During the three-month period ended March 31, 2011, we realized pretax investment losses of $405 million ($263 million after-tax) as a result of the recognition of other-than-temporary impairment losses on certain securities, and we realized pretax investment losses, net of gains, of $144 million ($94 million after-tax) from sales and redemptions of securities, primarily as a result of an implemented plan to reduce the risk exposure in our investment portfolio coupled with the continued decline in the credit worthiness of certain issuers.

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

⁽¹⁾ Includes $28 for credit-related impairments and $175 from change in intent to sell securities

⁽²⁾Consisted completely of credit-related impairments

Impact of Derivative and Hedging Activities

Our derivative activities include foreign currency, interest rate and credit default swaps in variable interest entities that are consolidated, cross-currency interest rate swaps associated with our senior notes due February 2017 and February 2022, and an interest rate swap associated with our variable interest rate yen-denominated debt. We realized pretax investment gains, net of losses, of $80 million ($52 million after-tax) for the three-month period ended March 31, 2012, compared with pretax investment losses, net of gains, of $30 million ($19 million after tax) for the same period in 2011, as a result of valuing the swaps described above.

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 primarily purchase yen-denominated assets to 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. However, it is important to distinguish between translating and converting foreign currency. Except for a limited number of transactions, we do not actually convert yen into dollars.

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 and not 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 34.7% for the three-month period ended March 31, 2012, compared with 34.2% for the same period in 2011.

Earnings Guidance

We communicate earnings guidance in this report based on the growth in net earnings per diluted share.

51

However, certain items that cannot be predicted or that are outside of management’s control may have a significant impact on actual results. Therefore, our comparison of net earnings includes certain assumptions to reflect the limitations that are inherent in projections of net earnings. In comparing period-over-period results, we exclude the effect of realized investment gains and losses (securities transactions, impairments, and the impact of derivative and hedging activities) and nonrecurring items. We also assume no impact from foreign currency translation on the Aflac Japan segment and the Parent Company’s yen-denominated interest expense for a given period in relation to the prior period.

Subject to the preceding assumptions, our objective for 2012 is to increase net earnings per diluted share by 3% to 6% over 2011 as restated for the change in accounting for deferred acquisition costs, compared with our prior stated objective of 2% to 5% growth. This range reflects the impact of portfolio derisking and investing significant cash flows at low interest rates. Once the effects of our investment derisking activities and low interest rate yields on investments have been integrated into our financial results, we expect the rate of earnings growth in 2013 to improve over 2012. Based on our stated objective for 2012, the following table shows the likely results for 2012 net earnings per diluted share, including the impact of foreign currency translation using various yen/dollar exchange rate scenarios.

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 measure and evaluate our insurance segments’ financial performance using operating earnings on a pretax basis. We define segment operating earnings as the profits we derive from our operations before realized investment gains and losses (securities transactions, impairments, and the impact of derivative and hedging activities) and nonrecurring items. We believe that an analysis of segment pretax operating earnings is vitally important to an understanding of the 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.

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. Premium income, or earned premiums, is a financial performance measure that reflects collected or due premiums that have been earned ratably on policies in force during the reporting period.

Prior-year amounts have been adjusted for the adoption of accounting guidance on January 1, 2012 related to deferred policy acquisition costs.

The percentage increases in premium income in yen reflect the growth of premiums in force. Annualized premiums in force increased 8.9% to 1.38 trillion yen as of March 31, 2012, compared with 1.27 trillion yen as of March 31, 2011. The increase in annualized premiums in force in yen reflect 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 $16.8 billion at March 31, 2012, compared with $15.3 billion a year ago.

Aflac Japan maintains a portfolio of dollar-denominated and reverse-dual currency securities (yen-denominated debt securities with dollar coupon payments). Dollar-denominated investment income from these assets accounted for approximately 35% of Aflac Japan’s investment income in the first three months of 2012, compared with 33% a year ago. In periods 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 periods 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 36% of Aflac Japan’s investment income during the first three months of 2012 and 2011.

Aflac Japan’s financial results for the first quarter of 2011 reflected a provision of 3.0 billion yen, or $37 million, for claims related to the earthquake and tsunami that occurred in Japan on March 11, 2011. These claims were offset by reserve releases and reinsurance of 2.0 billion yen, or $25 million, resulting in a net income statement impact of 1.0 billion yen, or $12 million, in 2011. The financial results also reflected .7 billion yen, or $8 million, of operating expenses in the first quarter of 2011 resulting from the earthquake and tsunami. Based on our claims experience to date and our claims estimates, we believe that our initial provision is adequate. The natural disaster and its related events have not had a material impact on our financial position or results of operations.

In the past several years, the benefit ratio for our health products has been positively impacted by favorable claim trends, primarily in our cancer product line. We expect this downward claim trend to continue. However, for several years, the rate of decline in Aflac Japan's benefit ratio has moderated, due primarily to strong sales results in our ordinary products, including WAYS and child endowment. These products have higher benefit ratios and lower expense ratios than our third sector products. The benefit ratio has also been impacted by the effect of low investment yields and portfolio derisking, both of which impact our profit margin by reducing the spread between investment yields and required interest on policy reserves. In the three-month period ended March 31, 2012, the benefit ratio increased and the operating expense ratio decreased, resulting in a lower pretax operating profit margin, compared with the same period in 2011. For the full year of 2012, we expect to achieve our profit objectives through better-than-average premium growth associated with the life products and somewhat lower profit margins due to the change in business mix discussed above.

Aflac Japan Sales

Aflac Japan's first quarter 2012 production set an all-time new annualized premium sales record for the third consecutive quarter. Aflac Japan's new annualized premium sales exceeded our expectations in the first quarter of 2012 and increased 53.8% in yen, compared with the same period in 2011. The following table presents Aflac Japan’s new annualized premium sales for the periods ended March 31.

	In Dollars						In Yen
	Three Months						Three Months
(In millions of dollars and billions of yen)	2012			2011			2012		2011

Increase (decrease) over comparable period in prior year	59.3		%	24.0		%	53.8	%	12.6	%

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

The bank channel generated new annualized premium sales of 24.3 billion yen in the first quarter of 2012, an increase of 208.9% over the first quarter of 2011. Bank channel sales accounted for 46% of new annualized premium sales for Aflac Japan in the first quarter of 2012, compared with 23% during the same period a year ago. WAYS, a unique hybrid whole-life product that we first introduced in 2006 and introduced to the bank channel in 2009, has been a significant contributor to bank sales growth. The average premium for WAYS sold through the bank channel, the primary distribution outlet for this product, is about ten times the average premium for cancer and medical products, making it a strong contributor to revenue growth. The profit margin on WAYS is lower than our health insurance products, however the profit margin is significantly enhanced when policyholders elect to pay premiums upfront using the “discounted advance premium” option. More than 90% of customers at banks choose this payment option. Sales of WAYS were 23.2 billion yen during the first quarter of 2012, an increase of 283.4% over the the first quarter of 2011.

The foundation of Aflac Japan's product portfolio has been, and continues to be, our third sector cancer and medical products. Cancer insurance sales increased 14.2% during the first quarter of 2012, compared with the same period a year ago. The increase primarily reflected sales of the new base cancer policy, DAYS, which was introduced at the end of March 2011, and DAYS PLUS, which upgrades older cancer policies. The enhancements in this new base policy are a response to the changes in cancer treatment as well as our commitment to being the number one provider of cancer insurance in Japan. We are convinced that the affordable cancer products Aflac Japan provides will continue to be an important part of our product portfolio.

Medical insurance sales decreased 6.1% during the first quarter of 2012, compared with the same period a year ago, primarily due to our traditional sales channels' focus on selling our DAYS and DAYS PLUS cancer policies. Despite the comparative sales decrease, we maintained our position as the number one seller of medical insurance policies in Japan. We upgraded our New EVER policy toward the end of January 2012, and initial results of the product revision have been positive. With continued cost pressure on Japan’s health care system, we expect the need for medical products will continue to rise in the future, and we remain encouraged about the outlook for the medical insurance market.

At March 31, 2012, we had agreements to sell our products at 372 banks, or more than 90% of the total number of banks in Japan. We have seen sales steadily improve at many of these bank branches as training has taken place and as many banks expand their offerings of Aflac products. We believe we have significantly more banks selling our

55

third sector insurance products than any other insurer operating in Japan. Japanese consumers rely on banks not only to provide traditional bank services, but also to provide insurance solutions, among other services. Approximately 80% of our customers at banks are new customers to Aflac. We believe our long-standing and strong relationships within the Japanese banking sector, along with our strategic preparations, have proven to be an advantage as this channel opened up for our types of products. Our partnership with banks provides us with a wider demographic of potential customers than we would otherwise have been able to reach, and it also allows banks to expand their product and service offerings to consumers.

We remain committed to selling through our traditional channels. These channels include affiliated corporate agencies, independent corporate agencies and individual agencies. In the first quarter of 2012, we recruited more than 940 new sales agencies. At March 31, 2012, Aflac Japan was represented by approximately 19,500 sales agencies and more than 121,400 licensed sales associates employed by those agencies.

Overall, Aflac Japan performed well in the first quarter of 2012. We believe that there is a continued need for our products in Japan. Based on the sales results from this quarter, we now expect Aflac Japan's full year 2012 new annualized premium sales to increase 10%, compared with our previous expectation of a sales decline.

Aflac Japan Investments

Growth of investment income in yen is affected by available cash flow from operations, the timing of investing the cash flow, yields on new investments, and the effect of yen/dollar exchange rates on dollar-denominated investment income. Aflac Japan has invested in privately issued securities to secure higher yields than those available on Japanese government or other public corporate bonds, while still adhering to prudent standards for credit quality. All of our privately issued securities are rated investment grade at the time of purchase. These securities are generally issued with documentation consistent with standard medium-term note programs. In addition, many of these investments have protective covenants appropriate to the specific issuer, industry and country. These covenants often require the issuer to adhere to specific financial ratios and give priority to repayment of our investment under certain circumstances.

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

	Three Months
	2012		2011
New money yield - yen only	1.94	%	2.36	%
New money yield - blended	2.03		3.16
Return on average invested assets, net of investment expenses	3.18		3.31

The decrease in Aflac Japan's new money yield reflects the low level of interest rates. At March 31, 2012, the yield on Aflac Japan’s investment portfolio, including dollar-denominated investments, was 3.18%, compared with 3.56% a year ago. 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.

Japanese Economy

The Bank of Japan's April 2012 Monthly Report of Recent Economic Developments stated that Japan's economic activity has shown some signs of improvement, however it has remained relatively flat. Exports and production have remained more or less flat. Public investment has begun to increase, housing investment has continued to increase and private consumption has remained firm. The report projected that Japan's economy is expected to return to a moderate recovery path as the pace of recovery in overseas economies improves and reconstruction demand related to the tsunami and earthquake disaster gradually strengthens. Exports and production are expected to increase moderately and public investment and housing investment are expected to continue to increase, while private consumption is expected to remain firm. For additional information, see the Japanese Economy subsection of MD&A in our annual report to shareholders for the year ended December 31, 2011.

Japanese Regulatory Environment

Japan’s Financial Services Agency (FSA) maintains a solvency standard, which is used by Japanese regulators to monitor the financial strength of insurance companies. The FSA has applied a revised method of calculating the solvency margin ratio for life insurance companies as of fiscal year-end 2011 (March 31, 2012) and encouraged the disclosure of the ratio as reference information as of fiscal year-end 2010 (March 31, 2011). The FSA had commented that the revision would generally reduce life insurance companies’ solvency margin ratios to approximately half the level of those reported under the current calculation method. Aflac Japan's solvency margin ratio, most recently reported as of December 31, 2011, was 985.8% using the former calculation method and, disclosed as reference information, was 547.3% under the new standards. As expected, based on the results of the calculation of the solvency margin ratio under the new standards, Aflac Japan’s relative position within the industry has not materially changed.

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. Currently, our products are being offered in approximately 1,000 post offices. Japan's three major political parties recently submitted legislation regarding postal reform. This legislation would merge two of the postal operating entities (the one that delivers the mail and the one that runs the post offices). We anticipate that this legislation will pass the Diet during the current Diet session scheduled to end in June 2012. However, at the current time, it is not possible to predict with any degree of certainty what impact, if any, this legislation will have on Aflac Japan's operations. Regardless, we believe that postal reform is unlikely to change Aflac Japan's relationship with the post office company.

The benefit ratio remained relatively stable in the first quarter of 2012, compared with the same period a year ago. The expense ratio decreased, resulting in an expansion in the pretax operating profit margin compared with the same period in 2011. For the remainder of 2012, we expect the benefit and expense ratios and pretax operating profit margin to be similar to those experienced in 2011.

Aflac U.S. Sales

In the first quarter of 2012, Aflac U.S. generated new annualized premium sales growth of 4.5%, compared with the same period in 2011. We believe this sales growth reflects our intense focus on supporting our field force with enhanced products, including group products, and other resources that help our sales force approach selling in the current economic environment more effectively.

disability sales increased 21.5%, critical care insurance sales (including cancer insurance) increased 5.7%, and hospital indemnity insurance sales decreased 7.7% in the first quarter of 2012, compared with the same period a year ago.

As part of our U.S. sales strategy, we continue to focus on growing and enhancing the effectiveness of our U.S. sales force. We recruited 6,700 new sales associates in the first quarter of 2012, resulting in approximately 76,300 licensed sales associates as of March 31, 2012.

In addition to expanding the size and capabilities of our traditional sales force, we are encouraged about the opportunities to broaden our distribution by pursuing and strengthening relationships with insurance brokers. Insurance brokers have been a historically underleveraged sales channel for Aflac, so we have been developing relationships with brokers the past several years that complement our traditional distribution system. We have a management team experienced in broker sales, and we are supporting this initiative with streamlined products, targeted broker-specific advertising campaigns, customized enrollment technology, and competitive compensation. At the beginning of 2012, Aflac U.S. launched an initiative to address the largest insurance brokers. We believe that we have significant potential for growth in this larger-case market.

Our group products sold through Aflac Group Insurance have enhanced sales opportunities not only for brokers but also for our traditional sales force of individual associates, especially when they pursue larger payroll accounts. For the three-month period ended March 31, 2012, sales from Aflac Group Insurance increased 38.4%, compared with the same period in the prior year, to $50 million, representing 14% of new annualized premium sales for Aflac U.S.

Although we remain somewhat cautious in our short-term sales outlook for Aflac U.S. due to the relatively weak economic environment, our longer-term view has not changed. We believe the need for the products we sell remains strong, and that the United States provides a vast and accessible market for our products. We are taking measures to better reach potential customers through our product and distribution strategy, which includes broadening our product portfolio to include group products in addition to our traditional individually issued products. The addition of the group product platform and our growing broker initiative only serve to enhance our ability to leverage the Aflac brand to reach employees at more companies, large and small, across the United States. Following the passage of health care reform in 2010, we believe employers and consumers will increasingly come to understand the need for the products we offer, just as they have in Japan. For 2012, our objective is for Aflac U.S. new annualized premium sales to increase in the range of 3% to 8%.

Aflac U.S. Investments

	Three Months
	2012		2011
New money yield	4.80	%	5.77	%
Return on average invested assets, net of investment expenses	6.48		6.42

The decrease in the U.S. new money yield for the three-month period ended March 31, 2012 reflects a low level of interest rates and tightening credit spreads. At March 31, 2012, the portfolio yield on Aflac’s U.S. portfolio was 6.66%, compared with 6.84% a year ago. 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.

U.S. Economy

Operating in the U.S. economy continues to be challenging. We generated sales growth that exceeded our expectations for 2011, but even so, ongoing low confidence levels from consumers and small businesses coupled with fewer employees at the worksite continue to pose challenges to our U.S. sales growth. Our group products and growing relationships with insurance brokers that handle the larger-case market are helping us as we expand our reach to do business with larger businesses. However, most of our business continues to revolve around small business owners and accounts with fewer than 100 employees. Small businesses, in particular, have proven to be especially vulnerable to ongoing economic weakness, and both small-business owners and their workers are anxious about the future. Workers at small businesses are holding back on increasing their spending for voluntary insurance products. Although we believe that the weakened U.S. economy has dampened our sales growth, we also believe our products remain affordable to the average American consumer. We believe that consumers’ underlying need for our U.S. product line remains strong, and that the United States remains a sizeable and attractive market for our products.

U.S. Regulatory Environment

In March 2010, President Barack Obama signed the Patient Protection and Affordable Care Act (PPACA) to give Americans of all ages and income levels access to comprehensive major medical health insurance. The primary subject of the new legislation is major medical insurance, therefore, the PPACA, as enacted, does not directly affect the design of our insurance products or our sales model. Our experience with Japan’s national health care environment leads us to believe that the need for our products will only increase over the coming years.

In July 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act, commonly known as the Dodd-Frank Act, which, among other things, created a Financial Stability and Oversight Council. The Council may designate by a two-thirds vote whether certain insurance companies and insurance holding companies pose a grave 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 of Governors of the U.S. Federal Reserve (the Board), including capital requirements, leverage limits, liquidity requirements and examinations. The Board may limit such company’s ability to enter into merger 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 Dodd-Frank Act also established a Federal Insurance Office 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. The Dodd-Frank Act requires extensive rule-making and other future regulatory action, which in some cases will take a period of years to implement. We believe that Aflac would not likely be considered a company that would pose a systemic risk to the financial stability of the United States. However, 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.

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, 2012, with the amounts that would have been reported had the exchange rate remained unchanged from December 31, 2011.

Impact of Foreign Exchange on Balance Sheet Items

(In millions)	As   Reported		Exchange                  Effect			Net of         Exchange Effect
Yen/dollar exchange rate(1)	82.19					77.74

Policy liabilities	93,004		(4,855		)	97,859
Total liabilities	101,909		(5,103		)	107,012

⁽¹⁾The exchange rate at March 31, 2012, was 82.19 yen to one dollar, or 5.4% weaker than the December 31, 2011, exchange rate of 77.74.

Market Risks of Financial Instruments

Our investment philosophy is to maximize investment income while emphasizing liquidity, safety and quality. Our investment objective, subject to appropriate risk constraints, is to fund policyholder obligations and other liabilities in a manner that enhances shareholders’ equity. We seek to achieve this objective through a diversified portfolio of fixed-income investments that reflects the characteristics of the liabilities it supports. Aflac invests primarily within the fixed income securities markets.

2011.

Because we invest in fixed-income 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 investment income and other expenses. While we have been investing a portion of our yen cash flow in dollar-denominated securities, most of Aflac Japan's investments, cash and liabilities are yen-denominated. When yen-denominated securities mature or are sold, the proceeds are generally reinvested in yen-denominated securities. Aflac Japan holds these yen-denominated assets to fund its yen-denominated policy obligations. In addition, Aflac Incorporated has yen-denominated debt obligations.

Although we generally do not convert yen into dollars, 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 accumulated other comprehensive income.

Aflac Japan maintains a portfolio of reverse-dual currency securities (yen-denominated debt securities with dollar coupon payments), which exposes Aflac to changes in foreign exchange rates. This foreign currency effect is accounted for as a component of unrealized gains or losses on available-for-sale securities in accumulated other comprehensive income. When the yen strengthens against the dollar, shareholders’ equity is negatively impacted and, conversely, when the yen weakens against the dollar, shareholders’ equity is positively impacted. Aflac Japan invests a portion of its assets in reverse-dual currency securities to provide a higher yield than those available on Japanese government or other public corporate bonds, while still adhering to prudent standards of credit quality. The yen/dollar exchange rate would have to strengthen to approximately 46 before the yield on these instruments would equal that of a comparable yen-denominated instrument.

On a consolidated basis, we attempt to minimize the exposure of shareholders' equity to foreign currency translation fluctuations. 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

Prior-year amounts have been adjusted for the adoption of accounting guidance on January 1, 2012 related to deferred policy acquisition costs.

We are required to consolidate certain variable interest entities (VIEs). Prior to consolidation, our beneficial interest in certain VIEs was a yen-denominated available-for-sale fixed maturity security. Upon consolidation, the original yen-denominated investment was derecognized and the underlying U.S. dollar-denominated fixed-maturity or perpetual securities and cross-currency swaps were recognized. While the combination of a U.S. dollar-denominated investment and cross-currency swap economically creates a yen-denominated investment, these investments will create foreign currency fluctuations but have no impact on our net investment hedge position. For additional information, see the Hedging Activities subsection of MD&A.

Some of the consolidated VIEs in our Aflac Japan 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.

We are exposed to economic currency risk only when yen funds are actually converted into dollars. This primarily occurs when we repatriate yen-denominated funds from Aflac Japan to Aflac U.S., which is generally done annually. 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 repatriation may be used to service Aflac Incorporated's yen-denominated notes payable with the remainder converted into dollars.

62

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, 2012, and December 31, 2011, would be as follows:

(In millions)	March 31, 2012			December 31, 2011
Effect on yen-denominated debt and perpetual securities	$	(10,027	)	$	(9,715	)
Effect on dollar-denominated debt and perpetual securities	(1,890		)	(1,900		)
Effect on total debt and perpetual securities	$	(11,917	)	$	(11,615	)

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 attempt to match the duration of our assets with the duration of our 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.

We entered into an interest rate swap agreement related to our 5.5 billion yen variable interest rate Samurai notes that we issued in July 2011. This agreement effectively converted the variable interest rate notes to fixed rate notes to eliminate the volatility in our interest expense. We also have interest rate swaps related to some of our consolidated VIEs. These interest rate swaps are primarily used to convert interest receipts on floating-rate fixed-maturity securities contracts to fixed rates. For further information, see Note 4 of the accompanying Notes to the Consolidated Financial Statements and Note 8 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, 2011.

Credit Risk

Our investment activities expose us to credit risk, which is a consequence of extending credit and/or carrying investment positions. However, we continue to adhere to prudent standards for credit quality. We accomplish this by considering our product needs and overall corporate objectives, in addition to credit risk. In evaluating the initial rating, we look at the overall senior issuer rating, the explicit rating for the actual issue or the rating for the security class, and, where applicable, the appropriate designation from the Securities Valuation Office (SVO) of the National Association of Insurance Commissioners (NAIC). All of our securities have ratings from either a nationally recognized statistical rating organization, the SVO of the NAIC, or are assigned ratings by us based on NAIC rules. In addition, we perform extensive internal credit reviews to ensure that we are consistent in applying rating criteria for all of our securities.

We use specific criteria to judge the credit quality of both existing and prospective investments. Furthermore, we use several methods to monitor these criteria, including credit rating services and internal credit analysis. The ratings references in the two tables below are based on the ratings designations provided by major credit rating agencies (Moody's, S&P and Fitch) or, if not rated, are determined based on the ratings assigned by the SVO of the NAIC and/or our internal credit analysis of such securities. For investment grade securities where the ratings assigned by the major credit agencies are not equivalent, in periods prior to the first quarter of 2012 we used the highest rating that was assigned; as of the first quarter of 2012 and prospectively, we are using 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.

⁽¹⁾ See the preceding discussion in this section of MD&A regarding the change in credit rating methodology effective March 31, 2012

Purchases of securities from period to period are determined based on diversification objectives, relative value and availability of investment opportunities, while meeting our investment policy guidelines for liquidity, safety and quality. We did not purchase any perpetual securities during the periods presented in the table above. The increase in purchases of AA rated securities during the first quarter of 2012 was primarily due to purchases of JGBs. The purchases of BB or lower rated securities in 2012 and 2011 was due to a limited program that was initiated in May 2011 to 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 a third party firm specializing in this asset class. Its mandate requires a minimum average credit quality of BB-/Ba3, no loans rated below B/B2, and no 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.

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

⁽¹⁾ See the preceding discussion in this section of MD&A regarding the change in credit rating methodology effective March 31, 2012

As of March 31, 2012, 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, 2012, and December 31, 2011. 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 (LTII) securities are debt instruments with fixed maturities. Our Upper Tier II (UTII) 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.

As indicated in the table above, the percentage of our investment portfolio comprising subordinated fixed maturities and perpetual securities investments has declined due primarily to sales and impairments resulting from an implemented plan to reduce the risk exposure in our investment portfolio. See the Investment Concentrations section below for more information on these derisking activities.

Portfolio Composition

For information regarding the amortized cost for our investments in debt and perpetual securities, the cost for equity securities and the fair values of these investments, refer to Note 3 of the Notes to the Consolidated Financial Statements.

Investment Concentrations

As of March 31, 2012, one of our largest investment industry sector concentrations was banks and financial institutions. Throughout 2008 and during the first half of 2009, concerns related to troubled residential mortgages in the United States, United Kingdom and Europe spread to structured investment securities. As a result, banks and financial institutions suffered significant write-downs of asset values, which pressured banks and financial institutions to seek capital and liquidity support. National governments responded with various forms of support, ranging from guarantees on new and existing debt to significant injections of capital. In the second half of 2009, asset valuations generally improved, and banks and other institutions continued to use exchanges and tender offers to enhance their core capital. However, 2010 brought new concerns about the fiscal integrity of peripheral European sovereign nations, and in 2011, concerns about the fiscal integrity of peripheral European sovereigns persisted due to the inability of Eurozone leaders to establish an effective solution. As a result, most financial institutions in the Euro area have faced both liquidity and asset valuation pressures. Greece, Ireland, and most recently, Portugal were forced to accept external funding aid in various forms to meet their financial obligations, as public markets were not accessible. Nationalization and/or recapitalization, along with loss-sharing among bondholders, all remain distinct risks for financial institutions. While European politicians have become increasingly hesitant to put taxpayers at risk, with few exceptions, we believe nationalizations and burden-sharing among debt holders remain options of last resort.

See Note 3 of the Notes to the Consolidated Financial Statements for a discussion of our investment discipline and further discussion of our investment industry sector concentration in banks and financial institutions.

As previously disclosed, we own long-dated debt instruments in support of our long-dated policyholder obligations. Included in our largest global investment holdings are positions that date back many years. Additionally, the concentration of certain of our holdings of individual credit exposures has grown over time through merger and consolidation activity. Beginning in 2005, we have generally limited our investment exposures to individual issuers to no more than 5% of total adjusted capital (TAC) on a statutory accounting basis, with the exception of obligations of the Japanese and U.S. governments. However, existing investment exposures that exceeded 5% of TAC at the time this guidance was adopted, or exposures that may exceed this threshold from time to time through merger and consolidation activity, are not automatically reduced through sales of the issuers’ securities but rather are reduced over time consistent with our investment policy.

Investments in Certain European Countries

With the periphery of Europe garnering the attention of markets, we are disclosing our investment exposure to Greece, Ireland, Italy, Portugal, and Spain. These countries are at the epicenter of the European debt crisis, and the developments affecting these countries in turn affect the other 12 countries inextricably linked to these five countries through their collective membership in the Economic and Monetary Union and resultant adoption of a single common currency - the euro.

The primary factor considered when determining domicile 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.

We had no direct exposure to Greece as of March 31, 2012 and December 31, 2011. Our direct investment exposure to Ireland, Italy, Portugal and Spain and the related maturities of those investments were as follows:

We do not have any unfunded exposure in the European countries shown in the preceding table, and we have not entered into any hedges to mitigate credit risk for our funded exposure. The banks and financial institutions investments in Ireland, Italy, Portugal and Spain represented 5% of total investments in the banks and financial institutions sector at March 31, 2012 and December 31, 2011, and 1% of total investments in debt and perpetual securities at March 31, 2012 and December 31, 2011.

Ireland

As of March 31, 2012, our total direct exposure to Ireland was $517 million at amortized cost, comprised senior

69

unsecured obligations. Senior securities issued by the Bank of Ireland with amortized costs and fair values totaling $243 million and $125 million, respectively, were rated below investment grade. We believe that these unrealized losses were more closely linked to the Irish government's aggressive approach to addressing its debt burden, which included at one point potentially imposing losses on senior debt holders of certain non-viable Irish banks. While the political risk of burden-sharing remains, it significantly subsided during the second half of 2011, as the government has shifted its focus to reducing its debt burden related to the EU/IMF program rather than disrupt the progress made in restoring stability to the Irish banking sector. This Irish bank is current on its obligation to us, and we believe it has the ability to meet its obligations to us. In addition, as of March 31, 2012, we had the intent to hold this investment to recovery in value. As a result, we did not recognize an other-than-temporary impairment for this investment as of March 31, 2012. The other senior security holdings in Ireland were issued by DEPFA Bank PLC and had an amortized cost of $274 million as of March 31, 2012. DEPFA is an Irish-domiciled and licensed financial institution that is a wholly owned subsidiary of Hypo Real Estate Holding, a Germany licensed and regulated financial institution.  Due to this ownership by a German parent, DEPFA has not been included in the Republic of Ireland's bank re-structuring and capitalization plan.  DEPFA was current on its obligation to us and was rated investment grade at Baa3/BBB/BBB+ by Moody's, S&P and Fitch, respectively, as of March 31, 2012.

There have been no additional ratings actions by Moody's since it downgraded Ireland's foreign currency long-term debt rating from Baa3 to Ba1 on July 12, 2011. Moody's affirmed its rating of Ireland on February 13, 2012.  S&P placed Ireland's foreign currency long-term debt rating of BBB+ on negative watch on December 5, 2011 and subsequently removed the watch on January 13, 2012. On December 16, 2011, Fitch placed its foreign currency long-term debt rating of BBB+ for Ireland on negative watch. Fitch affirmed its rating of Ireland on January 27, 2012.

Italy

During the second half of 2011, the European sovereign crisis shifted focus from Greece and moved to other periphery European sovereigns, including Italy. We believe the focus on Italy has been driven by a combination of factors which, separately in a normal market environment, would have a limited impact on the fiscal profile and financing capabilities of a developed market government, like Italy's. The factors include the EU leadership's inability to solve the Greece fiscal problem, weak economic growth, a high overall debt profile, and a lack of political will to address the government's budget.

As of March 31, 2012, our total direct exposure to Italy was $2.4 billion, at amortized cost. This exposure comprised $304 million of direct investment in the sovereign of Italy; a senior unsecured bank obligation of $183 million; and several utility and industrial companies of $915 million and $1.0 billion, respectively.

We expect the operating environment will be difficult in 2012 as Italy's government implements austerity measures to reduce deficits. Meaningful economic growth will be difficult due to the aforementioned austerity measures and a contraction of bank credit. Although there has been substantial improvement in the political environment and the fiscal outlook has improved recently, Italy's economic and ratings profile is expected to remain under pressure in the short-term.

Corporates, especially utilities, domiciled in Italy will continue to carry sovereign rating risk, but we expect they will continue to meet obligations due to factors including high barriers to entry, necessity of product/service, good operating cash flow, leading market positions and well-diversified product and market mix.

Italy's foreign currency long-term debt rating was downgraded by Moody's from Aa2 to A2 on October 4, 2011 and was further downgraded one notch by Moody's to A3 on February 13, 2012. S&P placed Italy's long-term debt rating of A on negative watch on December 5, 2011 and subsequently downgraded the rating to BBB+ on January 13, 2012. Italy's foreign currency long-term debt rating was downgraded by Fitch from AA- to A+ on October 7, 2011. Italy's rating was again placed on negative watch by Fitch on December 16, 2011, and was subsequently downgraded to A- on January 27, 2012.

As of March 31, 2012, all of our Italian exposures were rated investment-grade and were current on their obligations to us, and we believe they have the ability to meet their obligations to us.

Portugal

As of March 31, 2012, our total direct exposure to Portugal was $294 million, at amortized cost. All of this exposure is to two electric utility issuers domiciled in Portugal; Redes Energeticas Nacionas SGPS, S.A. (REN) and

70

Energias de Portugal SA (EDP). Our exposure to REN and EDP was $122 million and $173 million, respectively, at amortized cost.

REN, an electric transmission operator, was rated Ba1/BB+ by Moody's and S&P, respectively, as of March 31, 2012. Our investment in REN was classified as below investment grade. As of March 31, 2012, REN was current on its obligations to us, and we believe it has the ability to meet its obligations to us.

EDP, an integrated electric utility, was rated Ba1/BB+/BBB+ by Moody's, S&P, and Fitch, respectively, as of March 31, 2012. Our investments issued by EDP were classified as below investment grade. As of December 31, 2011, our investments in EDP had been classified as investment grade. EDP’s debt rating from Moody’s had been Baa3 since July 8, 2011. However, following Moody’s downgrade of Portugal to Ba3 on February 13, 2012, EDP’s debt rating was downgraded to Ba1 on February 16, 2012. S&P placed EDP’s foreign issuer credit rating on credit watch negative on December 8, 2011 and subsequently downgraded it from BBB to BB+ on February 1, 2012. Due to these downgrades, we classified our investments in EDP as below investment grade effective February 2012 and transferred these investments from the held-to-maturity portfolio to the available-for-sale portfolio. As of March 31, 2012, EDP was current on its obligations to us, and we believe it has the ability to meet its obligations to us.

Utilities domiciled in Portugal will continue to carry sovereign rating risk and could experience difficulty in accessing capital markets because of that risk. However, we expect they will continue to meet debt obligations as a result of factors including high barriers to entry, necessity of product/service, good operating cash flow, market leading positions and well-diversified markets.

Spain

During 2011, the Euro area sovereign crisis shifted to other periphery European sovereigns, including Spain. The factors influencing the crisis in Spain include the EU leadership's inability to solve the Greece fiscal problem, high unemployment and other social burdens, the rapid decline of its real estate/construction sector, a high fiscal deficit and a difficulty at both the federal and regional level to address the government's fiscal budget.

We expect the operating environment will be difficult in 2012 as Spain's government implements austerity measures to reduce deficits at both the federal and regional levels. In addition, meaningful economic growth will be difficult due to the aforementioned austerity measures and a contraction of bank credit. Greater uncertainty over their fiscal profiles could make it difficult for most regional governments in Spain to obtain reasonable financing for existing and new debt facilities. Therefore, Spain's and its regional governments' economic and ratings profile is expected to remain under pressure in the short-term.

As of March 31, 2012, our total direct exposure to Spain was $2.5 billion, at amortized cost. This exposure comprised $602 million of investments in sub-sovereign (i.e. regional governments) issuers; a senior unsecured bank obligation of $182 million; several Lower Tier II bank obligations of $302 million; and Spain-domiciled utilities and industrials of $876 million and $508 million, respectively.

Corporates, especially utilities, domiciled in Spain will continue to carry sovereign rating risk, but we expect they will continue to meet obligations due to some or all of the following factors including high barriers to entry, necessity of product/service, good operating cash flow, market leading positions and well-diversified product and market mix.

Spain's foreign currency long-term debt rating was downgraded by Moody's from Aa2 to A1 on October 18, 2011 and was further downgraded two notches by Moody's to A3 on February 13, 2012. S&P placed Spain's foreign currency long-term rating of AA- on negative watch on December 5, 2011 and subsequently downgraded the rating to A on January 13, 2012 and then to BBB+ on April 26, 2012. Spain's foreign currency long-term debt rating of AA- was placed on negative watch by Fitch on December 16, 2011 and was subsequently downgraded to A on January 27, 2012.

As of March 31, 2012, all of our Spain-domiciled exposures were rated investment grade and were current on their obligations to us, and we believe they have the ability to meet their obligations to us.

Monitoring and mitigating exposure

During most of 2011, we saw the Euro area sovereign crisis persist and escalate.  As a result, we saw contagion risk expand from periphery Eurozone sovereign credits to also include core Eurozone sovereign credits.  Apart from

71

our direct investments in sovereign debt, we view our European financial holdings as our largest indirect exposure due to the high correlation between financials and the sovereign from both a ratings and economics perspective.  Our other significant source of indirect exposure is via our investment in fixed income securities issued by integrated electric utilities and industrials domiciled in periphery Eurozone countries.  As of March 31, 2012, we had investments of $10.8 billion in European financials (including $2.1 billion in the United Kingdom), $2.1 billion in periphery Eurozone utilities and $1.6 billion in periphery Eurozone industrials, at amortized cost.  Our large and diversified exposure requires a considerable allocation of resources. In order to maintain up-to-date knowledge of conditions, we use a number of tools and resources including news reports, rating agency commentary and reports, company reports, third party research, and academic and regulator commentary.   In addition, we regularly conduct teleconference and on-site interviews with executives of companies in which we have invested in Europe, rating agency analysts and Euro area regulatory officials to assist us in the monitoring and evaluation of conditions in the Euro area. 

Due to the persistency of this crisis and the opportunity to obtain better financial data from the European Banking Authority (EBA) stress tests performed during the year, we performed a more intense and comprehensive stress test on all our financial institutional holdings.  Our stress test incorporated the development of several negative events, including the restructuring of European periphery sovereigns and an overall deterioration in various capital ratios.  The results of the test assisted us in identifying those credits more likely to experience a serious credit event resulting from a large restructuring event and considering implementing risk mitigation strategies, including, but not limited to, redemption, impairment, sale, or use of credit derivatives. It should be noted that the majority of our holdings are structured as privately issued securities and therefore, other than impairment, there can be no assurance that these risk mitigation strategies would be effective or could be easily executed.

Additionally, in the second half of 2011, we performed a general stress test of our entire investment portfolio based on the recurrence of conditions similar to those experienced in 2008.  These conditions incorporated several events, including default of one or more of the Euro area sovereign credits, strengthening of the yen, recession in Japan, Europe and the United States, and a general contraction in available credit.  The test contemplated both direct and indirect exposures.  The results assisted us in identifying those credits more likely to experience a serious credit event in the coming quarters and possibly implementing risk mitigation strategies, including, but not limited to, redemption, impairment, sale, or use of credit derivatives. As mentioned above, the majority of our holdings are structured as privately issued securities and therefore, other than impairment, there can be no assurance that these risk mitigation strategies would be effective or could be easily executed.

In addition, several of our fixed income investments issued by periphery European sub-sovereigns and periphery Eurozone domiciled utilities contain covenants that enable us to seek an early redemption of our security.  The covenants contained in these instruments vary from put options that vest should the issuer be downgraded to below investment grade by a rating agency, obligations to maintain leverage below a certain level, obligations to maintain interest coverage ratios above a certain level or a combination of the above.  On an amortized cost basis, as of March 31, 2012, we had $1.3 billion in securities issued by periphery sub-sovereigns and corporates containing below-investment-grade put options, of which $383 million were issued by sub-sovereign entities and $900 million were issued by corporate and utility companies.  As of March 31, 2012, we had $815 million in securities issued by periphery corporate and utility companies that contained a leverage covenant, an interest coverage covenant, or a combination of both.

In February 2012, Moody's announced that it will be reviewing several European banks for possible downgrades. The review is expected to be completed by the end of June 2012.  While the results of the review are not known at this time, early indications are that as much as $4.8 billion of amortized cost of our holdings are subject to these possible ratings actions.

Derisking

During 2011 and continuing into the first quarter of 2012, we pursued strategic investment activities to lower the risk profile of our investment portfolio. Our primary focus during the first quarter of 2012 was on reducing our exposure to perpetual and other subordinated securities of European issuers, particularly in the financial sector. As a result of our investment derisking activities in 2011 and the first quarter of 2012, we have experienced significant reductions in peripheral Eurozone, perpetual, and financial exposures on an amortized cost basis. At the start of 2008, sovereign and financial investments in peripheral Eurozone countries comprised 5.9% of total investments and cash, declining to 2.1% by the end of the first quarter of 2012. At the start of 2008, investments in perpetual securities comprised 14.7% of total investments and cash, declining to 5.5% by the end of the first quarter of 2012. As a result of these derisking activities, we have no direct sovereign or financial investment exposure to Greece or Portugal, and we have only

72

senior indebtedness in Ireland.

Securities by Type of Issuance

We have investments in both publicly and privately issued securities. The outstanding amount of a particular issuance, as well as the level of activity in a particular issuance and market conditions, including credit events and the interest rate environment, affect liquidity regardless of whether it is publicly or privately issued.

The following table details investment securities by type of issuance.

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

The decrease in privately issued securities as a percentage of total debt and perpetual securities was due primarily to sales and impairments of investments and the allocation of new investments to JGBs during the first three months of 2012.

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. Aflac Japan’s investments in

73

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. Most of our privately issued securities are 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 are required.

In May 2011, we initiated a limited program to 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 a third party firm specializing in this asset class. Its mandate requires a minimum average credit quality of BB-/Ba3, no loans rated below B/B2, and no 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. As of March 31, 2012, our investments in this program totaled $154 million at amortized cost.

Excluding the senior secured bank loans discussed above that were rated below investment grade when initially purchased, below-investment-grade debt and perpetual securities represented 5.5% of total debt and perpetual securities at March 31, 2012 and December 31, 2011, at amortized cost. Debt and perpetual securities classified as below investment grade at March 31, 2012 and December 31, 2011 were generally reported as available for sale and carried at fair value.

Occasionally, a debt or perpetual security will be split rated. This occurs when one rating agency rates the security as investment grade while another rating agency rates the same security as below investment grade. As of the first quarter of 2012, our policy is to utilize the second lowest rating designation assigned to the security which in this case where there are only two ratings - one investment grade and one below investment grade - would result in the security being rated as below investment grade.  In the event that the second lowest rating designation from the major credit rating agencies (Moody's, S&P and Fitch) is investment grade, our policies do not preclude us from assigning a below-investment-grade rating if our own internal analysis shows a credit deterioration has occurred and our assessment results in a rating below that which is assigned by such agencies. Our review in those cases includes evaluating the issuer’s credit position as well as current market pricing and other factors, such as the issuer’s or security’s inclusion on a credit rating downgrade watch list. Split-rated securities, excluding the senior secured bank loan investments discussed above, totaled $2.9 billion as of March 31, 2012, and $2.7 billion as of December 31, 2011, and represented 3% of total debt and perpetual securities, at amortized cost, at March 31, 2012, and December 31, 2011. The 10 largest split-rated securities as of March 31, 2012, were as follows:

⁽¹⁾ Perpetual security

Declines in fair value noted above were impacted by changes in interest rates and credit spreads, yen/dollar exchange rates, and issuer credit status. However, we believe it would be inappropriate to recognize impairment charges because we believe the changes in fair value are temporary. See the Investment Concentrations and Unrealized Investment Gains and Losses sections in Note 3 of the Notes to the Consolidated Financial Statements for further discussions of unrealized losses related to Ireland, financial institutions including perpetual securities, and other corporate investments.

Investment Valuation and Cash

We estimate the fair values of our securities available for sale on a monthly basis. We monitor the estimated fair values derived from our discounted cash flow pricing model and those 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.

Due to our reliance on third-party pricing services to provide valuations on 51% of our Level 2 available-for-sale portfolio and 3% of our Level 2 held-to-maturity portfolio (for disclosure purposes), we regularly discuss and review pricing methodologies with the investment custodian. We also review the custodians' Service Organization Control (SOC 1) report for the period covering the current year to gain satisfaction with the controls and control environment of the custodian.

See Note 5 of the Notes to the Consolidated Financial Statements for the fair value hierarchy classification of our securities available for sale as of March 31, 2012.

Cash and cash equivalents totaled $2.21 billion, or 2.1% of total investments and cash, as of March 31, 2012, compared with $2.25 billion, or 2.2%, at December 31, 2011. For a discussion of the factors affecting our cash balance, see the Operating Activities, Investing Activities and Financing Activities subsections of this MD&A.

For additional information concerning our investments, see Notes 3, 4, and 5 of the Notes to the Consolidated Financial Statements.

Notes Payable

Notes payable totaled $4.0 billion at March 31, 2012, compared with $3.3 billion at December 31, 2011. In February 2012, the Parent Company issued $750 million of senior notes through a U.S. public debt offering.The ratio of debt to total capitalization (debt plus shareholders’ equity, excluding the unrealized gains and losses on investment securities and derivatives) was 24.5% as of March 31, 2012, compared with 21.0% as of December 31, 2011. See Note 6 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 9 of the accompanying Notes to the Consolidated Financial Statements and Note 13 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2011.

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 through March 2012. 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.

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 a portfolio of dollar-denominated securities, which serve as an economic currency hedge of a portion of our investment in Aflac Japan. The foreign exchange gains and losses related to this portfolio are taxable in Japan and the U.S. when the securities mature or are sold. Until maturity or sale, deferred tax expense or benefit associated with the foreign exchange gains or losses are recognized in other comprehensive income. Second, we have designated the

78

majority of the Parent Company’s yen-denominated liabilities (Samurai and Uridashi notes and yen-denominated loans) as a hedge of our investment in Aflac Japan. At the beginning of each quarter, we make our net investment hedge designation. If the total of our designated yen-denominated liabilities is equal to or less than our net investment in Aflac Japan, the hedge is deemed to be effective and the related exchange effect on the liabilities is reported in the unrealized foreign currency component of other comprehensive income. Should these designated yen-denominated liabilities exceed our investment in Aflac Japan, the foreign exchange effect on the portion of the liabilities that exceeds our investment in Aflac Japan would be recognized in net earnings. We estimate that if our yen-denominated liabilities exceeded our 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, 2012 and 2011, respectively.

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 U.S. dollar-denominated 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.

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

(In millions)	March 31, 2012			December 31, 2011
Aflac Japan yen-denominated net assets	$	4,486		$	3,255
Parent Company yen-denominated net liabilities	(821		)	(1,258		)
Consolidated yen-denominated net assets (liabilities) subject to foreign currency translation fluctuations	$	3,665		$	1,997

Prior-year amounts have been adjusted for the adoption of accounting guidance on January 1, 2012 related to deferred policy acquisition costs.

Cash Flow Hedges

We have freestanding derivative instruments that are reported in the consolidated balance sheet at fair value and are reported in other assets and other liabilities. During 2011, we de-designated certain of the derivatives used in cash flow hedging strategies as a result of determining that these swaps would no longer be highly effective in offsetting the cash flows of the hedged item. The $7 million after-tax gain recorded in accumulated other comprehensive income for these swaps is being amortized into earnings over the expected life of the respective hedged item. The amount amortized from accumulated other comprehensive income into earnings related to these swaps was immaterial for the three-month period ended March 31, 2012. As of March 31, 2012, a couple of the freestanding foreign currency swaps that are used within VIEs to hedge the risk arising from changes in foreign currency exchange rates still qualified for hedge accounting. See Note 4 of the Notes to the Consolidated Financial Statements for additional information.

We have an interest rate swap agreement related to our 5.5 billion yen variable interest rate Samurai notes that we issued in July 2011. By entering into this contract, we swapped the variable interest rate to a fixed interest rate of 1.475%. We have designated this interest rate swap as a hedge of the variability in our interest cash flows associated with the variable interest rate Samurai notes. This hedge was effective during the three-month periods ended March 31, 2012 and 2011, respectively. See Note 4 of the Notes to the Consolidated Financial Statements for additional information.

Off-Balance Sheet Arrangements

    As of March 31, 2012, we had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 14 of the Notes to the Consolidated Financial Statements in our annual report to shareholders for the year ended December 31, 2011, 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)	2012		2011
Dividends declared or paid by Aflac	$	0	$	141
Management fees paid by Aflac	67		57

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.

The Parent Company also accesses debt security markets to provide additional sources of capital. In May 2009, we filed a shelf registration statement with the SEC that allows us to issue an indefinite amount of senior and subordinated debt, in one or more series, from time to time through May 2012. As of March 31, 2012, we had issued $2.75 billion of senior notes under this registration statement. Due to the pending expiration of this registration statement, in May 2012 we filed a shelf registration statement with the SEC 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 December 2011, 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 January 2014. 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 6 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.

Our financial statements adequately 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 do not have any restrictive financial covenants related to our notes payable, and we were in compliance with all of the covenants of our notes payable at March 31, 2012. 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 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, 2011, for more information on our securities lending activity. 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.

80

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)	2012			2011
Operating activities	$	3,556		$	2,167
Investing activities	(4,436		)	(2,013		)

Total	$	3,556	$	2,167

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)	2012			2011
Aflac Japan	$	(4,256	)	$	(1,900	)
Aflac U.S. and other operations	(180		)	(113		)
Total	$	(4,436	)	$	(2,013	)

Prudent portfolio management dictates that we attempt to match the duration of our assets with the duration of our liabilities. Currently, when our debt 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 market opportunities arise, we dispose of selected debt and perpetual securities that are available for sale to improve the duration matching of our assets and liabilities, improve future investment yields, and/or rebalance 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 debt and perpetual securities available for sale during the three-month period ended March 31, 2012, compared with 2% during the same period a year ago.

Financing Activities

Consolidated cash provided by financing activities was $901 million in the first three months of 2012, compared with consolidated cash used by financing activities of $171 million for the same period of 2011. Cash returned to shareholders through dividends and treasury stock purchases was $158 million during the three-month period ended March 31, 2012, compared with $319 million during the three-month period ended March 31, 2011.

In February 2012, the Parent Company issued $400 million and $350 million of senior notes that are due in February 2017 and February 2022, respectively. We plan to use proceeds from this debt offering to redeem 26.6 billion yen (approximately $324 million using the March 31, 2012, exchange rate) of Samurai notes when they mature in June 2012.

We have no restrictive financial covenants related to our notes payable. We were in compliance with all of the covenants of our notes payable at March 31, 2012.

During the first three months of 2012, we did not repurchase any shares of our common stock as part of our share repurchase program. As of March 31, 2012, a remaining balance of 24.4 million shares of our common stock was available for purchase under a share repurchase authorization by our board of directors in 2008.

Cash dividends paid to shareholders were $.33 per share in the first quarter of 2012, compared with $.30 per share in the first quarter of 2011. The following table presents the dividend activity for the three-month periods ended March 31.

(In millions)	2012		2011

In April 2012, the board of directors declared the second quarter cash dividend of $.33 per share. The dividend is payable on June 1, 2012, to shareholders of record at the close of business on May 16, 2012.

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 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. Aflac’s company action level RBC ratio was estimated to be within the range of 500% and 540% as of March 31, 2012. Aflac’s RBC ratio remains high and reflects a strong capital and surplus position.

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. See the Japanese Regulatory Environment subsection of this MD&A for a discussion of changes to the calculation of the solvency margin ratio. Aflac Japan's solvency margin ratio, most recently reported as of December 31, 2011, was 985.8% using the former calculation method, which significantly exceeded regulatory minimums, and was 547.3% under the new standards, disclosed as reference information. As expected, based on the results of the calculation of the solvency margin ratio under the new standards, our relative position within the industry has not materially changed. Given the low interest rate environment and the

82

sensitivity of the solvency margin ratio to interest rate changes, we have recently taken actions to improve our solvency margin, including entering into surplus relief reinsurance contracts and increasing our allocation of JGBs classified as held to maturity. We continue to evaluate other alternatives for reducing the sensitivity of the solvency margin ratio against interest rate and foreign exchange rate changes.

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)	2012		2011

Item 4. Controls and Procedures

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.

Changes in Internal Control Over Financial Reporting

There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the first fiscal quarter of 2012 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

In April 2012, we implemented our SAP® worldwide financial reporting system. Our management believes that the implementation of this system will improve and enhance our internal control over financial reporting. This system will be used for our financial reporting beginning with the second quarter of 2012.
