In Tokyo, Japan, Aflac has three primary campuses. The first campus includes a building, owned by Aflac, for the customer call center, the claims department, information technology departments, and training facility. It also includes a leased property, which houses our policy administration and customer service departments. The second campus comprises leased space, which serves as our Japan branch headquarters and houses administrative and investment support functions for the Japan branch. The third campus comprises leased space for the information technology departments. Aflac also leases additional office space in Tokyo, along with regional offices located throughout the country.

Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to inform the reader about matters affecting the financial condition and results of operations of Aflac Incorporated and its subsidiaries for the three-year period ended December 31, 2015. As a result, the following discussion should be read in conjunction with the related consolidated financial statements and notes. This MD&A is divided into the following sections:
In August 2015, we paid off $300 million of 3.45% fixed-rate senior notes upon their maturity. In August 2015, we paid off a 5.0 billion yen loan at its maturity date (a total of approximately $41 million using the exchange rate at the maturity date). In July 2015, we paid off a 10.0 billion yen loan at its maturity date (a total of approximately $81 million using the exchange rate at the maturity date). In March 2015, the Parent Company issued $1.0 billion of senior notes through a U.S. public debt offering. We entered into cross-currency interest rate swaps to economically convert the U.S. dollar denominated principal and interest on the senior notes we issued into yen-denominated obligations. In April 2015, the Parent Company used the proceeds from the March 2015 issuance of our fixed-rate senior notes to redeem all of its $850 million 8.50% fixed-rate senior notes due May 2019 and to pay a portion of the corresponding $230 million make-whole premium due to the investors of these notes.
We 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 U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards CodificationTM (ASC). The preparation of financial statements in conformity with U.S. 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 93% of our assets and 77% of our liabilities are reported as of December 31, 2015, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.
Aflac's investments, primarily consisting of debt, perpetual and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, we determine the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third party pricing vendors. For the majority of privately issued securities within our investment portfolio, a third party pricing vendor has developed valuation models to determine fair values. For the remaining privately issued securities, we use non-binding price quotes from outside brokers. We also routinely review our investments that have experienced declines in fair value to determine if the decline is other than temporary. The identification of distressed investments, the determination of fair value if not publicly traded and the assessment of whether a decline is other than temporary involve significant management judgment.
Our derivative activities include foreign currency, interest rate and credit default swaps in VIEs that are consolidated; foreign currency swaps associated with certain senior notes and our subordinated debentures; foreign currency forwards and options used in hedging foreign exchange risk and options on interest rate swaps (or interest rate swaptions) used in hedging interest rate risk on U.S. dollar-denominated securities in Aflac Japan's portfolio; and foreign currency forwards and options used to economically hedge certain portions of forecasted cash flows denominated in yen. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, and interest volatility. With the exception of the derivatives associated with our VIE investments, the fair values of the derivatives referenced above are based on the amounts we would expect to receive or pay to terminate the derivatives. For derivatives associated with VIEs where we are the primary beneficiary, we receive valuations from a third party pricing vendor.
In computing the estimate of unpaid policy claims, we consider many factors, including the benefits and amounts available under the policy; the volume and demographics of the policies exposed to claims; and internal business practices, such as incurred date assignment and current claim administrative practices. We monitor these conditions closely and make adjustments to the liability as actual experience emerges. Claim levels are generally stable from period to period; however, fluctuations in claim levels may occur. In calculating the unpaid policy claim liability, we do not calculate a range of estimates. The following table shows the expected sensitivity of the unpaid policy claims liability as of December 31, 2015, to changes in severity and frequency of claims.
Aflac defines operating earnings (a non-U.S. GAAP financial measure) as the profits derived from operations. Operating earnings includes interest cash flows associated with notes payable but excludes items that cannot be predicted or that are outside of management's control, such as realized investment gains and losses from securities transactions, impairments, and derivative and hedging activities; nonrecurring items; and other non-operating income (loss) from net earnings. Aflac's derivative activities are primarily used to hedge foreign exchange and interest rate risk in our investment portfolio as well as manage foreign exchange risk for certain notes payable and forecasted cash flows denominated in yen. Our management uses operating earnings to evaluate the financial performance of Aflac’s insurance operations because realized gains and losses from securities transactions, impairments, and derivative and hedging activities, as well as other and nonrecurring items, tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with the Company’s insurance operations, and therefore may obscure the underlying fundamentals and trends in Aflac’s insurance operations.
The following table is a reconciliation of items impacting operating and net earnings and operating and net earnings per diluted share for the years ended December 31.
(1) Excludes a gain of $54, $28 and $6, after tax, in 2015, 2014 and 2013, respectively, related to the interest rate component of the change in fair value of foreign currency swaps on notes payable which is classified as an operating gain when analyzing segment operations
The following table details our pretax impairment losses by investment category for the years ended December 31.
Our derivative activities include foreign currency swaps and credit default swaps held in consolidated VIEs; foreign currency forwards and options, interest rate swaptions and futures on certain fixed-maturity securities; foreign currency forwards and options that economically hedge certain portions of forecasted cash flows denominated in yen; and foreign currency swaps associated with certain senior notes and our subordinated debentures. During 2015, we realized pretax investment losses, net of gains, of $10 million ($7 million after-tax), compared with pretax investment gains, net of losses, of $31 million ($20 million after-tax) in 2014 and pretax investment gains, net of losses, of $336 million ($218 million after-tax) in 2013 as a result of valuing these derivatives, net of the effects of hedge accounting. For a description of other items that could be included in the Impact of Derivative and Hedging Activities, see the Hedging Activities subsection of MD&A and Note 4 of the accompanying Notes to the Consolidated Financial Statements.
During the second quarter of 2015, the make-whole premium paid to the investors of our 8.50% fixed-rate senior notes for the early redemption of those notes was recorded as a $230 million pretax non-operating loss ($150 million after-tax, or $.35 per diluted share). The Company also includes the accounting impacts of remeasurement associated with changes in the yen/dollar exchange rate as an other non-operating item.
Aflac Japan’s premiums and most of its investment income are received in yen. Claims and expenses are paid in yen, and we have yen-denominated assets that support yen-denominated policy liabilities. These and other yen-denominated financial statement items are translated into dollars for financial reporting purposes. We translate Aflac Japan’s yen-denominated income statement into dollars using an average exchange rate for the reporting period, and we translate its yen-denominated balance sheet using the exchange rate at the end of the period.
Due to the size of Aflac Japan, where our functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on our reported results. In periods when the yen weakens, translating yen into dollars results in fewer dollars being reported. When the yen strengthens, translating yen into dollars results in more dollars being reported. Consequently, yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. As a result, we view foreign currency translation as a financial reporting issue for Aflac rather than an economic event to our Company or shareholders. Because changes in exchange rates distort the growth rates of our operations, management evaluates Aflac’s financial performance excluding the impact of foreign currency translation.
(1)Excludes realized investment gains/losses (securities transactions, impairments, and the impact of derivative and hedging activities), nonrecurring items, and other non-operating income (loss) in 2016 and 2015
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. U.S. 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.
The relatively small change in premium income in yen for 2015 and 2014 was influenced by the impact of weak first sector sales in 2015, 2014 and 2013 in addition to premiums ceded in reinsurance transactions during those same years. Annualized premiums in force at December 31, 2015, were 1.62 trillion yen, compared with 1.59 trillion yen in 2014 and
Sales of cancer insurance continued to be strong following the introduction at the end of the third quarter of 2014 of New Cancer DAYS, which includes an exclusive policy sold through Japan Post. Cancer insurance sales were up 40.6% in 2015, compared with 2014. Aflac Japan enhanced its medical product with new riders in June 2015. This revision provides better protection against critical diseases such as cancer, heart attack and stroke. With continued cost pressure on Japan’s health care system, we expect the need for third sector products will continue to rise in the future, and we remain convinced that the medical and cancer products Aflac Japan provides will continue to be an important part of our product portfolio.
At December 31, 2015, we had agreements to sell our products at 372 banks, approximately 90% of the total number of banks in Japan. Bank channel sales accounted for 14.9% of new annualized premium sales in 2015 for Aflac Japan, compared with 21.5% in 2014.
Aflac Japan invests in U.S. dollar-denominated securities, including publicly-traded investment grade and below investment grade corporate fixed-maturity securities, and has entered into foreign currency forwards and options to hedge the currency risk on the fair value of the U.S. dollar securities. In 2015, as part of our normal portfolio management and asset allocation process, Aflac Japan increased the allocation of investments to a U.S. dollar senior secured bank loan program by approximately $950 million and to a U.S. dollar high yield corporate bond program by approximately $650 million, all of which had been funded as of December 31, 2015.
See the Analysis of Financial Condition section of this MD&A for further discussion of these investment programs.
Funds available for investment include cash flows from operations, investment income, and funds generated from maturities, redemptions, securities lending, and other securities transactions. Securities lending is also used from time to time to accelerate the availability of funds for investment. Purchases of securities from period to period are determined based on multiple objectives including appropriate portfolio diversification, the relative value of a potential investment and availability of investment opportunities, liquidity, credit and other risk factors while adhering to our investment policy guidelines. Aflac Japan purchased debt security investments at an aggregate acquisition cost of approximately 663.6 billion yen in 2015 (approximately $5.5 billion), 1.0 trillion yen in 2014 (approximately $10.0 billion) and 2.5 trillion yen in 2013 (approximately $25.4 billion).
The following table presents the composition of debt security purchases by sector and equity security purchases for Aflac Japan, as a percentage of acquisition cost, for the years ended December 31.
The following table presents the composition of total investments by sector, at cost or amortized cost, and cash for Aflac Japan ($85.1 billion in 2015 and 2014) as of December 31.
(2)Includes .2% of perpetual securities at December 31, 2015 and 2014
Yen-denominated debt and perpetual securities accounted for 72.8% of Aflac Japan's total debt and perpetual securities at December 31, 2015, compared with 75.7% at December 31, 2014, at amortized cost.
The benefit ratio decreased in 2015, compared with 2014, due to mix of business changes and continued favorable claims experience. The expense ratio increased in 2015, compared with 2014, primarily due to increased spending
One Day PaySM is a claims initiative that we have focused on at Aflac U.S. to process, approve and pay eligible claims in just one day. We believe that along with our brand and relevant products, this claims practice will help Aflac stand out from competitors.
With the evolving business market and the coverage standardization that will result from health care reform in the United States, we believe Aflac's voluntary products will become more relevant than ever. Our products provide cash benefits that can be used to help with increasing out-of-pocket medical expenses, help cover household costs, or protect against income and asset loss. Our group products and relationships with insurance brokers that handle the larger-case market are helping us as we expand our reach selling to larger businesses. We are regularly evaluating the marketplace to identify opportunities to bring the most relevant, cost-effective products to our customers. We believe the need for our products remains very strong, and we continue to work on enhancing our distribution capabilities to access employers of all sizes, including initiatives that benefit our field force and the broker community. At the same time, we are seeking opportunities to leverage our brand strength and attractive product portfolio in the evolving health care environment. For 2016, our objective is for Aflac U.S. new annualized premium sales to increase 3% to 5%, with a long-term compound annual growth rate at or above the voluntary market growth rate of 5%.
On December 18, 2015, the president signed into law the Consolidated Appropriations Act which included a revision to delay implementation of the Excise Tax on High Cost Plans, better known as the "Cadillac tax.” This tax was originally scheduled to begin in 2017, was previously delayed until 2018, and is now scheduled to begin in 2020. The tax consists of 40% of the cost of employer sponsored health coverage in excess of certain dollar thresholds. In general, only Aflac specified disease and fixed indemnity (i.e. supplemental health) products offered on a pre-tax basis are taken into account under this tax.
designated two insurers in 2013 and an additional insurer in 2014 as a Systemically Important Financial Institution (SIFI). On December 18, 2014, the president signed the Insurance Capital Standards Clarification Act into law. This legislation will clarify the Board’s authority to apply insurance-based capital standards for insurance companies subject to federal supervision. Although Aflac is a nonbank financial company predominantly engaged in financial activities as defined in the Dodd-Frank Act, we do not believe Aflac will be considered a company that poses a threat to the financial stability of the United States.
Penn Treaty Network Company and its subsidiary American Network Insurance Company (collectively referred to as Penn Treaty) were placed in rehabilitation on January 6, 2009, and remained in rehabilitation as of December 31, 2015. As of December 31, 2015, we were unable to estimate when or to what extent Penn Treaty will ultimately be declared insolvent, or the amount of the insolvency. As such, we have not established any accruals for guaranty fund assessments associated with Penn Treaty as of December 31, 2015.
Funds available for investment include cash flows from operations, investment income, and funds generated from maturities, redemptions, and other securities transactions. Purchases of securities from period to period are determined based on multiple objectives, including appropriate portfolio diversification, the relative value of a potential investment and availability of investment opportunities, liquidity, credit and other risk factors while adhering to our investment policy guidelines. Aflac U.S. purchased debt security investments at an aggregate acquisition cost of approximately $900 million in 2015, compared with $1.0 billion in 2014 and $1.2 billion in 2013. The following table presents the composition of debt security purchases by sector and other investment purchases for Aflac U.S., as a percentage of acquisition cost, for the years ended December 31.
(1)Includes .3% and .4% of perpetual securities at December 31, 2015 and 2014, respectively.
Corporate operating expenses consist primarily of personnel compensation, benefits, reinsurance retrocession activities, and facilities expenses. Corporate expenses, excluding investment and retrocession income, were $90 million in 2015, $91 million in 2014 and $79 million in 2013. Investment income included in reported corporate expenses was $22 million in 2015, $13 million in 2014 and $11 million in 2013, and net retrocession income was $7 million in 2015.
(1)The exchange rate at December 31, 2015, was 120.61 yen to one dollar, or .05% weaker than the December 31, 2014, exchange
The functional currency of Aflac Japan's insurance operations is the Japanese yen. All of Aflac Japan's premiums, claims and commissions are received or paid in yen, as are most of its other expenses. Most of Aflac Japan's cash and liabilities are yen-denominated. Aflac Japan's investments consisted of yen-denominated fixed income securities of $60.8
Aside from the activities discussed above, we generally do not convert yen into dollars; however, we do translate financial statement amounts from yen into dollars for financial reporting purposes. Therefore, reported amounts are affected by foreign currency fluctuations. We report unrealized foreign currency translation gains and losses in accumulated other comprehensive income. In periods when the yen weakens against the dollar, translating yen into dollars causes fewer dollars to be reported. When the yen strengthens, translating yen into dollars causes more dollars to be reported. The weakening of the yen relative to the dollar will generally adversely affect the value of our yen-denominated investments in dollar terms. We attempt to minimize the exposure of shareholders' equity to foreign currency. We accomplish this by investing a portion of Aflac Japan's investment portfolio in U.S. 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.
(2) Does not include the U.S. dollar-denominated corporate bonds for which we have entered into foreign currency derivatives as discussed in the Aflac Japan Investment subsection of MD&A
For additional information regarding our Aflac Japan net investment hedge, see the Hedging Activities subsection of MD&A.
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 monitor our investment portfolio on a quarterly basis utilizing a full valuation methodology, measuring price volatility, and sensitivity of the fair values of our investments to interest rate changes on the debt and perpetual securities we own. For example, if the current duration of a debt security or perpetual security is 10, then the fair value of that security will increase by approximately 10% if market interest rates decrease by 100 basis points, assuming all other factors remain constant. Likewise, the fair value of the debt security or perpetual security will decrease by approximately 10% if market interest rates increase by 100 basis points, assuming all other factors remain constant.
We continue to monitor the spread between our new money yield and the required interest assumption for newly issued products in both the United States and Japan and will re-evaluate those assumptions as necessary. Over the next two years, we have yen-denominated securities that will mature with yields in excess of Aflac Japan's current net investment yield of 2.82%. These securities total $723 million at amortized cost and have a weighted average yield of 4.23%. 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.
Periodically, depending on general economic conditions, we may enter into derivative transactions to hedge interest rate risk.
Purchases of securities from period to period are determined based on multiple objectives including appropriate portfolio diversification, the relative value of a potential investment and availability of investment opportunities, liquidity, credit and other risk factors while adhering to our investment policy guidelines. We did not purchase any perpetual securities during the periods presented in the table above. Total purchases comprise new money investments as well as the reinvestment of proceeds from investment disposals. The relatively higher purchases of AA rated securities in 2014 and 2013 were primarily due to the purchase of JGBs. The increase in purchases of A rated and BBB rated securities in 2015 was due primarily to the purchase of U.S. dollar-denominated corporate fixed-income publicly traded securities for the Aflac Japan portfolio. The significant increase in purchases of BB or lower rated securities in 2015 was due to increased investment in senior secured bank loans, most of which have below-investment-grade ratings, and investment in high yield corporate bonds. The bank loan investment program is managed externally by third party firms specializing in this asset class. This mandate requires a minimum average credit quality of BB-/Ba3, prohibits loan purchases rated below B/B2, and restricts exposure to any individual credit to less than 2% of the program’s assets. The objectives of this program include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates through the acquisition of floating rate assets. The objective of the high yield corporate bond investments is to enhance yield on invested assets and further diversify our credit risk. All investments must have a minimum rating of low BB using our above described rating methodology and are managed by our internal credit portfolio management team.
As of December 31, 2015, our direct and indirect exposure to securities in our investment portfolio that were guaranteed by third parties was immaterial both individually and in the aggregate.
The majority of our total investments in debt and perpetual securities was senior debt at December 31, 2015 and 2014. We also maintained investments in subordinated financial instruments that primarily consisted of Lower Tier II, Upper Tier II, and Tier I securities, listed in order of seniority. The Lower Tier II securities are debt instruments with fixed maturities. Our Upper Tier II and Tier I investments consisted of debt instruments with fixed maturities and perpetual securities, which have an economic maturity as opposed to a stated maturity.
The following table shows the subordination distribution of our debt and perpetual securities as of December 31.
Our 15 largest global investment exposures as of December 31, 2015, were as follows:
As previously disclosed, we own long-dated debt instruments in support of our long-dated policyholder obligations. Some of our largest global investment holdings are positions that were purchased many years ago and increased in size due to merger and consolidation activity among the issuing entities. In addition, many of our largest holdings are yen-denominated, therefore strengthening of the yen can increase our position in dollars, and weakening of the yen can decrease our position in dollars. Our global investment guidelines establish concentration limits for our investment portfolios.
(1) Includes total exposure to Puerto Rico of $1 million of required deposits, of which 72% has insurance of principal and interest.
The resolve to maintain the European Monetary Union (EMU) was tested in 2015 following the election of a new government in Greece, who rejected the requirements imposed in exchange for their previous support packages. After a period of tense negotiations which threatened Greece’s ability to remain in the EMU, agreements were made which provided Greece additional aid in exchange for an updated set of requirements. These actions have stabilized the situation currently.
Although recent economic indicators show improvement from the depths of the crisis across most of the Eurozone, overall economic activity remains subdued throughout the region. To support the return to sustainable economic growth, the ECB has launched a quantitative easing (QE) stimulus program.
Since the crisis first began, we have taken steps to improve the risk profile of our portfolio by selling certain holdings throughout Europe, including the peripheral Eurozone countries.
Our internal team of experienced credit professionals has continued to monitor the impact of the European sovereign crisis on our individual investment holdings' overall credit quality. Our analysis includes factors beyond a baseline assessment of a company's assets, operations, financial statements, and credit metrics that may provide support for the instruments we own. Specifically, for our investments in European banks and financial institutions, we monitor the importance of the issuer to its local financial system, the likelihood of government support, and our investment's position in the capital structure of the issuer. For our investments in European utilities, we monitor the role of the issuer in its local economy as a provider of necessary infrastructure, and we monitor the value of the underlying assets owned by the issuer. For our investment in European corporates, industrials, and other commercial entities, we monitor the general credit quality of the issuer, the geographical mix of the issuer's customers (i.e. domestic vs. foreign), the geographical breakdown of the issuer's assets (i.e. domestic versus foreign), the value of the underlying assets owned by the issuer, capitalization of the issuer, and overall profitability and cash generation ability of the issuer. We monitor NRSRO actions and the likely actions for our investment exposures, as well as overall market conditions. By performing these analyses, we make a determination on the probability of timely payment of principal and interest of the issuers of our investments.
Some of our peripheral Eurozone fixed-maturity investments contain covenants that we believe mitigate our risk to the issuer. These covenants could include put options that allow us to return our holdings to the issuer at a predetermined price, usually par, should the issuer be downgraded to below investment grade by a rating agency. Additionally, these covenants may include restrictions on the ability of the issuer to incur additional debt, sell assets, or provide collateral for indebtedness. As of December 31, 2015, all of the issuers of our holdings from peripheral Eurozone countries were current on their obligations to us, and we believe they have the ability to meet their obligations to us.
Although the situation had largely stabilized across Europe, the crisis in Greece that re-emerged in mid-2015 demonstrates certain risks remain as the area continues working to improve its economic footing. We continue to monitor the situation closely including the heightened interrelationship between political, monetary, fiscal, and economic forces; the pace of underlying structural reforms; the possibility of continued contagion to additional sovereigns and other entities; further stress on the banking systems throughout the region; and the impact on the underlying economic fundamentals throughout the Eurozone.
As of December 31, 2015, the weighted-average rating of our total fixed maturity oil and gas exposure is BBB, and 93% of this exposure is investment grade. Absent a major change in the outlook for oil prices, we expect the increase in market volatility surrounding these issuers to continue. This could lead to increased negative ratings activity from the public rating agencies for energy-related credit issuers. We do not currently expect our investments in these sub-sectors related to oil and gas to have a material impact on our results of operations.
We invest in senior secured bank loans primarily to U.S. corporate borrowers, most of which have below-investment-grade ratings. The program is managed externally by third party firms specializing in this asset class. This mandate requires a minimum average credit quality of BB-/Ba3, prohibits loan purchases rated below B/B2, and prohibits exposure to any individual credit greater than 2% of the program’s assets. The objectives of this program include enhancing the
Excluding the senior secured bank loans and certain high yield corporate bonds discussed above that were rated below investment grade when initially purchased, below-investment-grade debt and perpetual securities represented 3.1% of total debt and perpetual securities at December 31, 2015, compared with 3.4% at December 31, 2014, on an amortized cost basis. Debt and perpetual securities classified as below investment grade at December 31, 2015 and 2014 were generally reported as available for sale and carried at fair value.
The following table shows the 10 largest holdings with a split rating, and includes the determination between investment grade and below investment grade based on the above methodology as of December 31, 2015.
For the foreign currency and credit default swaps associated with our VIE investments for which we are the primary beneficiary, we bear the risk of foreign exchange and/or credit loss due to counterparty default even though we are not a direct counterparty to those contracts. We are a direct counterparty to the foreign currency swaps that we have on certain of our senior notes and subordinated debentures; foreign currency forwards; foreign currency options; and interest rate swaptions, therefore we are exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for our VIE and senior note and subordinated debenture swaps, foreign currency forwards and options, and swaptions is mitigated by collateral posting requirements the counterparty must meet. If collateral posting agreements are not in place, the counterparty risk associated with foreign currency forwards and foreign currency options is the risk that at expiry of the contract, the counterparty is unable to deliver the agreed upon amount of yen at the agreed upon price or delivery date, thus exposing the company to additional unhedged exposure to U.S. dollars in the Aflac Japan investment portfolio. See Note 4 of the Notes to the Consolidated Financial Statements for more information.
Market prices for equity securities are subject to fluctuation and consequently the amount realized in the subsequent sale of an investment may significantly differ from the reported market value. Fluctuation in the market price of a security may result from the relative price of alternative investments and general market conditions. These fluctuations could impact the Company’s consolidated results of operations or financial condition.
See Notes 1 and 3 of the Notes to the Consolidated Financial Statements for a discussion of our impairment policy.
The following table presents a distribution of unrealized losses on fixed maturities, perpetual securities, and equity securities by magnitude as of December 31, 2015.
Cash and cash equivalents totaled $4.4 billion, or 4.1% of total investments and cash, as of December 31, 2015, compared with $4.7 billion, or 4.3%, at December 31, 2014. For a discussion of the factors affecting our cash balance, see the Operating Activities, Investing Activities and Financing Activities subsections of this MD&A.
See Note 6 of the Notes to the Consolidated Financial Statements for additional information on our deferred policy acquisition costs.
(2) Elimination entry necessary due to recapture of a portion of policy liabilities ceded externally, as a result of the reinsurance retrocession transaction as described in Note 8 of the Notes to the Consolidated Financial Statements.
See Note 9 of the accompanying Notes to the Consolidated Financial Statements for additional information on our notes payable.
The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. On December 27, 2011, Japan's FSA announced the plans to enhance the stability of the LIPPC by extending the government's fiscal support of the LIPPC through March 2017. Accordingly, the FSA submitted legislation to the Diet on January 27, 2012 to extend the government's fiscal support framework, and the legislation was approved on March 30, 2012. Effective April 2014, the annual LIPPC contribution amount for the total life industry was lowered from 40 billion yen to 33 billion yen. Aflac Japan paid 2.2 billion yen in both 2015 and 2014 and 2.3 billion yen in 2013 for the policyholder protection fund.
The yen net asset figure calculated for hedging purposes differs from the yen-denominated net asset position as discussed in the Currency Risk subsection of MD&A. As disclosed in that subsection, the consolidation of the underlying assets in certain VIEs requires that we derecognize our yen-denominated investment in the VIE and recognize the underlying fixed-maturity or perpetual securities and cross-currency swaps. While these U.S. dollar investments will create foreign currency fluctuations, the combination of the U.S. dollar-denominated investment and the cross-currency swap economically creates a yen-denominated investment that qualifies for inclusion as a component of our investment in Aflac Japan. Similarly, the combination of the U.S. corporate bonds and the foreign currency forwards and options that we have entered into, as discussed in the Aflac Japan Investment subsection of MD&A, economically creates a yen-denominated investment that qualifies for inclusion as a component of our investment in Aflac Japan.
For the hedge of our net investment in Aflac Japan, we have designated certain of the Parent Company's yen-denominated liabilities, certain unhedged U.S. dollar investments and foreign currency forwards and options as a hedge of our net investment in Aflac Japan. Our consolidated yen-denominated net asset position was partially hedged at $1.2 billion as of December 31, 2015, compared with $1.6 billion as of December 31, 2014.
We had freestanding derivative instruments related to our consolidated VIE investments that are reported in the consolidated balance sheet at fair value within other assets and other liabilities. As of December 31, 2015, two of the freestanding swaps that are used within VIEs to hedge the risk arising from changes in foreign currency exchange rates qualified for hedge accounting.
At times we have entered into interest rate swaptions to mitigate the interest rate risk associated with our U.S. dollar-denominated fixed-maturities that support yen-denominated liabilities within our Aflac Japan segment.
As of December 31, 2015, we had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. See Note 15 of the Notes to the Consolidated Financial Statements for information on material unconditional purchase obligations that are not recorded on our balance sheet.
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 years ended December 31.
The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock, interest on its outstanding indebtedness and operating expenses. 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. We filed a shelf registration statement with the SEC in May 2015 that allows us to issue an indefinite amount of senior and subordinated debt, in one or more series, from time to time until May 2018. In March 2014, we filed a shelf registration statement with Japanese regulatory authorities that allows us to issue up to 100 billion yen of yen-denominated Samurai notes in Japan through March 2016. If issued, these yen-denominated Samurai notes would not be available to U.S. persons. We believe outside sources for additional debt and equity capital, if needed, will continue to be available. For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.
In August 2015, we paid off $300 million of 3.45% fixed-rate senior notes upon their maturity. In August 2015, we paid off a 5.0 billion yen loan at its maturity date (a total of approximately $41 million using the exchange rate at the maturity date). In July 2015, we paid off a 10.0 billion yen loan at its maturity date (a total of approximately $81 million using the exchange rate at the maturity date).
In November 2014, the Parent Company issued $750 million of senior notes through a U.S. public debt offering. The net proceeds were used for general corporate purposes. In July 2014, we redeemed 28.7 billion yen of our fixed rate Samauri notes and 5.5 billion yen of our variable rate Samurai notes upon their maturity (a total of approximately $335 million using the exchange rate on the date of redemption).
In June 2013, the Parent Company issued $700 million of senior notes through a U.S. public debt offering. We used part of these net proceeds for the debt redemptions in 2014. The balance of the net proceeds were used to repay or redeem, in whole or in part, the Parent Company’s $300 million senior notes that were due August 2015 and for general corporate purposes.
See Note 9 of the Notes to the Consolidated Financial Statements for further information on the debt issuances discussed above.
Cash returned to shareholders through dividends and treasury stock purchases was $2.0 billion in 2015, compared with $1.9 billion in 2014 and $1.4 billion in 2013.
See our preceding discussion in this Capital Resources and Liquidity section of MD&A regarding the 364-day uncommitted bilateral line of credit entered into by the Parent Company and Aflac in October 2015 in the amount of $100 million; the five-year senior unsecured revolving credit facility agreement entered into by the Parent Company and Aflac in September 2015 in the amount of 55 billion yen; and the $50 million uncommitted bilateral line of credit entered into by the Parent Company and Aflac in February 2015. As of December 31, 2015, no borrowings were outstanding under these lines of credit.
We were in compliance with all of the covenants of our notes payable and lines of credit at December 31, 2015.
Under share repurchase authorizations from our board of directors, we purchased 21.2 million shares of our common stock in the open market in 2015, compared with 19.7 million shares in 2014 and 13.2 million shares in 2013. In August 2015, Aflac's board of directors authorized the purchase of an additional 40 million shares of its common stock. As of December 31, 2015, a remaining balance of 48.4 million shares of our common stock was available for purchase under share repurchase authorizations by our board of directors. We currently plan to purchase $1.4 billion of our common stock in 2016, largely front-end loaded in the first half of the year. See Note 11 of the Notes to the Consolidated Financial Statements for additional information.
In addition to limitations and restrictions imposed by U.S. insurance regulators, Japan’s FSA may not allow profit repatriations from Aflac Japan if the transfers would cause Aflac Japan to lack sufficient financial strength for the protection of policyholders. The FSA maintains its own solvency standard which is quantified through the solvency margin ratio (SMR). Aflac Japan's SMR is sensitive to interest rate, credit spread and foreign exchange rate changes, therefore we continue to evaluate alternatives for reducing this sensitivity. In the event of a rapid change in market factors (such as interest rates), we have a senior unsecured revolving credit facility in the amount of 55 billion yen and a committed reinsurance facility in the amount of approximately 110 billion yen as capital contingency plans (see Notes 8 and 9 of the Notes to the Consolidated Financial Statements for additional information). We have already undertaken measures to mitigate the sensitivity of Aflac Japan's SMR. For example, we employ policy reserve matching (PRM), which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. For U.S. GAAP, PRM investments are categorized as available for sale. In the first quarter of 2015, Aflac Japan entered into a quota share arrangement to cede a portion of hospital benefits of one of our closed products. Under this coinsurance indemnity type of reinsurance, Aflac Japan released approximately 130 billion yen of FSA reserves. (See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on our investment strategies, hedging activities, and reinsurance, respectively.) As of December 31, 2015, Aflac Japan's SMR was 828%, compared with 857% at December 31, 2014.
Aflac is subject to the NAIC’s Own Risk and Solvency Assessment (ORSA), effective January 1, 2015. Through the ORSA requirements, Aflac is expected to regularly, no less than annually, conduct an ORSA to assess the adequacy of its risk management framework, and its current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level ORSA Summary Report annually to the lead state commissioner if the insurer is a member of an insurance group. Aflac filed its ORSA report on November 20, 2015 with the Nebraska Department of Insurance.
KPMG LLP, an independent registered public accounting firm, has issued an attestation report on the effectiveness of internal control over financial reporting as of December 31, 2015, which is included herein.
We have audited Aflac Incorporated's (the Company) internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Aflac Incorporated's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.
(1) Includes $102 in 2015 and $106 in 2014 of derivatives from consolidated variable interest entities
(2) Includes $293 in 2015 and $318 in 2014 of derivatives from consolidated variable interest entities
(1) Operating activities excludes and financing activities includes a cash outflow of $230 for the make-whole payment associated with the early extinguishment of debt
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 U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards CodificationTM (ASC). The preparation of financial statements in conformity with U.S. 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.
documents, there are certain powers that are retained by us that are considered significant in our conclusion that we are the primary beneficiary. These powers vary by structure but generally include the initial selection of the underlying collateral or, for collateralized debt obligations (CDOs), the reference credits to include in the structure; the ability to obtain the underlying collateral in the event of default; and the ability to appoint or dismiss key parties in the structure. In particular, our powers surrounding the underlying collateral were the most significant powers since those most significantly impact the economics of the VIE. We have no obligation to provide any continuing financial support to any of the entities in which we are the primary beneficiary. Our maximum loss is limited to our original investment. Neither we nor any of our creditors have the ability to obtain the underlying collateral, nor do we have control over the instruments in the VIEs, unless there is an event of default. For those entities where we are the primary beneficiary, the assets consolidated are fixed-maturity securities, perpetual securities, equity securities, and derivative instruments; collateral is reported separately under the captions fixed maturities- and perpetual securities- consolidated variable interest entities on our balance sheet.
If, after monitoring and analyses, management believes that fair value will not recover to amortized cost prior to the disposal of the security, we recognize an other-than-temporary impairment of the security. Once a security is considered to be other-than-temporarily impaired, the impairment loss is separated into two separate components: the portion of the impairment related to credit and the portion of the impairment related to factors other than credit. We recognize a charge to earnings for the credit-related portion of other-than-temporary impairments. Impairments related to factors other than credit are charged to earnings in the event we intend to sell the security prior to the recovery of its amortized cost or if it is more likely than not that we would be required to dispose of the security prior to recovery of its amortized cost; otherwise, non-credit-related other-than-temporary impairments are charged to other comprehensive income.
Other investments include policy loans, middle market loans, and other short-term investments with maturities of one year or less, but greater than 90 days, at the time of purchase and are stated at amortized cost, which approximates estimated fair value. We invest in middle market loans through participation rights that are accounted for as loan receivables and recorded at amortized cost on the acquisition date. Since we have the intent and ability to hold these loan receivables for the foreseeable future or until they mature, they are considered held for investment and are carried at adjusted amortized cost in the other investments line on our consolidated balance sheets. The adjusted amortized cost of the loan receivables reflects allowances for expected incurred losses estimated based on past events and current economic conditions as of each reporting date.
Derivatives and Hedging: Freestanding derivative instruments are reported in the consolidated balance sheet at fair value and are reported in other assets and other liabilities, with changes in value reported in earnings and/or other comprehensive income. These freestanding derivatives are interest rate swaps, foreign currency swaps, credit default swaps (CDSs), foreign currency forwards, foreign currency options, and options on interest rate swaps (or interest rate swaptions). Interest rate and foreign currency swaps are used within VIEs to hedge the risk arising from interest rate and currency exchange risk, while the CDSs are used to increase the yield and improve the diversification of the portfolio. Foreign currency forwards and options are used in hedging foreign exchange risk on U.S. dollar-denominated securities in Aflac Japan's portfolio. Foreign currency forwards and options are used to hedge certain portions of forecasted cash flows denominated in yen. Interest rate swaps are used to hedge the variability of interest cash flows associated with our variable interest rate notes. Cross-currency interest rate swaps, also referred to as foreign currency swaps, are used to economically convert certain U.S. dollar-denominated note obligations into yen-denominated principal and interest obligations. Interest rate swaptions have been used to hedge interest rate risk for certain U.S. dollar-denominated available-for-sale securities. We do not use derivatives for trading purposes, nor do we engage in leveraged derivative transactions.
liabilities and the change in estimated fair value of the derivatives are reported in the unrealized foreign currency component of other comprehensive income. Should these designated net investment hedge positions exceed our net investment in Aflac Japan, the foreign exchange effect on the portion that exceeds our investment in Aflac Japan would be recognized in current earnings within derivative and other gains (losses).
Policy Liabilities: Future policy benefits represent claims that are expected to occur in the future and are computed by a net level premium method using estimated future investment yields, persistency and recognized morbidity and mortality tables modified to reflect our experience, including a provision for adverse deviation. These assumptions are generally established at the time a policy is issued.
Treasury Stock: Treasury stock is reflected as a reduction of shareholders' equity at cost. We use the weighted-average purchase cost to determine the cost of treasury stock that is reissued. We include any gains and losses in additional paid-in capital when treasury stock is reissued.
Receivables - Troubled debt restructurings by creditors - classification of certain government-guaranteed mortgage loans upon foreclosure: In August 2014, the FASB issued updated guidance for troubled debt restructurings affecting creditors that hold government guaranteed mortgage loans. The guidance requires that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if certain conditions are met. We adopted the guidance as of January 1, 2015. The adoption of this guidance did not have a significant impact on our financial position or results of operations.
Disclosures about offsetting assets and liabilities: In December 2011, the FASB issued guidance to amend the disclosure requirements about offsetting assets and liabilities. The new guidance clarifies the FASB's intent concerning the application of existing offsetting disclosure requirements. Entities are required to disclose gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions when those activities are subject to an agreement similar to a master netting arrangement. The scope of this guidance was clarified and revised in January 2013 to apply to derivatives, repurchase agreements, reverse repurchase agreements, securities borrowing and securities lending arrangements. We adopted this guidance as of January 1, 2013. The adoption of this guidance impacted our financial statement disclosures, but it did not have an impact on our financial position or results of operations.
Fees paid to the federal government by health insurers: In July 2011, the FASB issued guidance on the accounting for fees owed by health insurers as mandated by the Patient Protection and Affordable Care Act as amended by the Health Care and Education Reconciliation Act, which imposes an annual fee on health insurers for each calendar year beginning on or after January 1, 2014. A health insurer's portion of the annual fee is payable by September 30 of the applicable calendar year once the entity provides health insurance for any U.S. health risk in that year. The accounting guidance specifies that the liability for the fee should be estimated and recorded in full in the applicable calendar year in which the fee is payable. We adopted this guidance as of January 1, 2014. The adoption of this guidance did not have a significant impact on our financial position or results of operations.
Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities: In January 2016, the FASB issued guidance to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions require that equity investments be measured at fair value with changes recognized in net income; that changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option be recognized in other comprehensive income; and that entities would make the assessment of the ability to realize a deferred tax asset (DTA) related to an available-for-sale (AFS) debt security in combination with the entity's other DTAs. The amendments are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is not permitted, with the exception of the own credit provision if an entity has elected to measure a liability at fair value. We are evaluating whether the adoption of this guidance will have a significant impact on our financial position, results of operations or disclosures.
Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments: In September 2015, the FASB issued guidance requiring that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustments are determined. In the same period’s financial statements, the acquirer is required to record income effects of the adjustments as if the accounting had been completed at the acquisition date. The acquirer is also required to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendment is effective for public business entities for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2015. The adoption of this guidance will not have a significant impact on our financial position or results of operations.
Financial Services - Insurance - Disclosures about Short-Duration Contracts: In May 2015, the FASB issued updated guidance requiring enhanced disclosures by all insurance entities that issue short-duration contracts. The amendments require insurance entities to disclose for annual reporting periods information about the liability for unpaid claims and claim adjustment expenses. The amendments also require insurance entities to disclose information about significant changes in methodologies and assumptions used to calculate the liability for unpaid claims and claim adjustment expenses. In addition, the amendments require insurance entities to disclose for annual and interim reporting periods a roll-forward of the liability for unpaid claims and claim adjustment expenses. For health insurance claims, the amendments require the disclosure of the total of incurred-but-not-reported liabilities and expected development on reported claims included in the liability for unpaid claims and claim adjustment expenses. The amendments are effective for public business entities for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. Early application of the amendments is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.
Interest - Imputation of Interest - Simplifying the presentation of debt issuance costs: In April 2015, the FASB issued updated guidance to simplify presentation of debt issuance costs. The updated guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. In August 2015, the FASB issued updated SEC Staff guidance pertaining to the presentation of debt issuance costs related to line-of-credit arrangements. The guidance states that an entity may defer and present debt issuance costs as an asset, subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The amendment is effective for annual periods and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.
Consolidation - Amendments to the consolidation analysis: In February 2015, the FASB issued updated guidance that affects evaluation of whether limited partnerships and similar legal entities (limited liability corporations and securitization structures, etc.) are VIEs, evaluation of whether fees paid to a decision maker or a service provider are a variable interest, and evaluation of the effect of fee arrangements and the effect of related parties on the determination of the primary beneficiary under the VIE model for consolidation. The updated guidance eliminates the presumption that a general partner should consolidate a limited partnership. Limited partnership and similar legal entities that provide partners with either substantive kick-out rights or substantive participating rights over the general partner will now be evaluated under the voting interest model rather than the VIE model for consolidation. In situations where no single party has a controlling financial interest in a VIE, the related party relationships under common control should be considered in their entirety in determining whether that common control group has a controlling financial interest in the VIE. The amendments in the updated guidance are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted, including adoption in an interim period. The adoption of this guidance will result in a reduction to the number of our investments that meet the definition of a VIE and will also reduce the number of VIEs required to be disclosed within our financial statements. The adoption of this guidance will impact our footnote disclosures, but will not have a significant impact on our financial position or results of operations.
Presentation of Financial Statements - Going Concern - Disclosure of uncertainties about an entity’s ability to continue as a going concern: In August 2014, the FASB issued this amendment that provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendment is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The adoption of this guidance will not have a significant impact on our financial position or results of operations.
Revenue from contracts with customers: In May 2014, the FASB issued updated guidance that affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB deferred the effective date for this standard to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is not permitted. The adoption of this guidance will not have a significant impact on our financial position or results of operations.
(1) Excluding a gain of $85 in 2015, $44 in 2014 and $10 in 2013 related to the interest rate component of the change in fair value of foreign currency swaps on notes payable which is classified as an operating gain when analyzing segment operations
(2) Includes a loss of $20 related to the change in value of yen repatriation received in advance of settlement of certain foreign currency derivatives. This loss was offset by derivative gains included in realized investment gains (losses).
Receivables: Receivables consist primarily of monthly insurance premiums due from individual policyholders or their employers for payroll deduction of premiums, net of an allowance for doubtful accounts. At December 31, 2015, $257 million, or 36.4% of total receivables, were related to Aflac Japan's operations, compared with $386 million, or 45.8%, at December 31, 2014.
The contractual maturities of our investments in fixed maturities at December 31, 2015, were as follows:
At December 31, 2015, the Parent Company and other business segments had portfolios of available-for-sale fixed-maturity securities totaling $512 million at amortized cost and $523 million at fair value, which are not included in the table above.
The majority of our perpetual securities are subordinated to other debt obligations of the issuer, but rank higher than the issuer's equity securities. Perpetual securities have characteristics of both debt and equity investments, along with unique features that create economic maturity dates for the securities. Although perpetual securities have no contractual maturity date, they have stated interest coupons that were fixed at their issuance and subsequently change to a floating short-term interest rate after some period of time. The instruments are generally callable by the issuer at the time of changing from a fixed coupon rate to a new variable rate of interest, which is determined by the combination of some market index plus a fixed amount of basis points. The net effect is to create an expected maturity date for the instrument. The economic maturities of our investments in perpetual securities, which were all reported as available for sale at December 31, 2015, were as follows:
One of our largest investment sector concentrations as of December 31, 2015, was banks and financial institutions. Within the countries we approve for investment opportunities, we primarily invest in financial institutions that are strategically crucial to each approved country's economy. The bank and financial institution sector is a highly regulated industry and plays a strategic role in the global economy.
Our investments in perpetual securities that are rated below investment grade and equity securities are evaluated for other-than-temporary impairment under our equity impairment model. Our equity impairment model focuses on the severity of a security’s decline in fair value coupled with the length of time the fair value of the security has been below cost or amortized cost and the financial condition and near-term prospects of the issuer. For equity securities, we also verify our intent to hold the securities until they recover in value. The fair value of our investments in equity securities may decline for various reasons, such as general market conditions which reflect prospects for the economy as a whole, or due to specific information pertaining to an industry or an individual company. For those equity securities evaluated for impairment under the equity impairment model that are in an unrealized loss position, if we believe the security will not recover in price within an acceptable period of time, or we do not have the intent to hold until recovery, we will record an other-than-temporary impairment of the investment and reduce the cost of the investment to its fair value on that date.
Information regarding changes in unrealized gains and losses from investments for the years ended December 31 follows:
For any significant declines in fair value of our fixed income or perpetual securities, we perform a more focused review of the related issuers' credit profile. For corporate issuers, we evaluate their assets, business profile including industry dynamics and competitive positioning, financial statements and other available financial data. For non-corporate issuers, we analyze all sources of credit support, including issuer-specific factors. We utilize information available in the public domain and, for certain private placement issuers, from consultations with the issuers directly. We also consider ratings from Nationally Recognized Statistical Rating Organizations (NRSROs), as well as the specific characteristics of the security we own including seniority in the issuer's capital structure, covenant predictions, or other relevant features. From these reviews, we evaluate the issuers' continued ability to service our investment through payment of interest and principal.
For any significant declines in fair value of our equity securities, we review the severity of the security’s decline in fair value coupled with the length of time the fair value of the security has been below cost. We also perform a more focused review of the financial condition and near-term prospects of the issuer, and determine whether we have the intent to hold the securities until they recover in value.
Assuming no credit-related factors, unrealized gains and losses are expected to diminish as investments near maturity. Based on our credit analysis, we believe that the issuers of our investments in the sectors shown in the table above have the ability to service their obligations to us.
Assuming no credit-related factors develop, as investments near maturity, the unrealized gains or losses are expected to diminish. Based on our credit analysis, we believe that the issuers of our investments in these sectors have the ability to service their obligations to us. Perpetual securities that had an amortized cost of $599 million and fair value of $630 million at December 31, 2014 matured or were called during 2015.
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, equity, and perpetual securities and foreign currency, and/or 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 (bank loans) and certain equity securities through unit trust structures, the underlying collateral assets and funding of our consolidated VIEs are generally static in nature and the underlying collateral and the reference corporate entities covered by any CDS contracts were all investment grade at the time of issuance.
We invest in bank loans through unit trust structures in which we are the only investor, requiring us to consolidate these trusts. These bank loans are classified as available-for-sale fixed-maturity securities in the financial statements. As of December 31, 2015, the amortized cost and fair value of our bank loan investments was $1.4 billion. As of December 31, 2014, the amortized cost and fair value of our bank loan investments was $501 million and $579 million, respectively. During the fourth quarter of 2015, we invested in yen-denominated public equities through a unit trust structure in which we are the only investor, requiring us to consolidate the trust under U.S. GAAP. These equities are classified as available-for-sale in the financial statements. As of December 31, 2015, the amortized cost and fair value of these equities was $363 million.
Details of our securities lending activities as of December 31 were as follows:
At December 31, 2015, debt securities with a fair value of $15 million were on deposit with regulatory authorities in
Our freestanding derivative financial instruments consist of: (1) foreign currency swaps and credit default swaps that are associated with investments in special-purpose entities, including VIEs where we are the primary beneficiary; (2) foreign currency forwards and options used in hedging foreign exchange risk on U.S. dollar-denominated securities in Aflac Japan's portfolio; (3) foreign currency forwards and options used to hedge foreign exchange risk from our net investment in Aflac Japan and economically hedge certain portions of forecasted cash flows denominated in yen; (4) swaps associated with our notes payable, consisting of cross-currency interest rate swaps, also referred to as foreign currency swaps, associated with certain senior notes and our subordinated debentures; and (5) options on interest rate swaps (or interest rate swaptions) and futures used to hedge interest rate risk for certain available-for-sale securities. We do not use derivative financial instruments for trading purposes, nor do we engage in leveraged derivative transactions. Some of our derivatives are designated as cash flow hedges, fair value hedges or net investment hedges; however, other derivatives do not qualify for hedge accounting or we elect not to designate them as an accounting hedge. We utilize a net investment hedge to mitigate foreign exchange exposure resulting from our net investment in Aflac Japan. In addition to designating derivatives as hedging instruments, we have designated our yen-denominated Samurai and Uridashi notes and yen-denominated loans as non-derivative hedging instruments for this net investment hedge.
The only CDS that we currently hold relates to components of an investment in a VIE and is used to assume credit risk related to an individual security. This CDS contract entitles the consolidated VIE to receive periodic fees in exchange for an obligation to compensate the derivative counterparties should the referenced security issuer experience a credit event, as defined in the contract.
Interest rate swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Typically, at the time a swap is
Interest rate swaptions are options on interest rate swaps. Interest rate collars are combinations of two swaption positions and are executed in order to hedge certain U.S. dollar-denominated available-for-sale securities that are held in the Aflac Japan segment. We use collars to protect against significant changes in the fair value associated with interest rate changes of our U.S. dollar-denominated available-for-sale securities. In order to maximize the efficiency of the collars while minimizing cost, we set the strike price on each collar so that the premium paid for the ‘payer leg’ is offset by the premium received for having sold the ‘receiver leg’.
For assessing hedge effectiveness of fair value hedges, qualitative methods may include the comparison of critical terms of the derivative to the hedged item, and quantitative methods may include regression or other statistical analysis of changes in fair value associated with the hedge relationship. Hedge ineffectiveness of the hedge relationships is measured each reporting period using the dollar offset method. For derivative instruments that are designated and qualify as fair value hedges, changes in the estimated fair value of the derivative, including amounts measured as ineffectiveness, and changes in the estimated fair value of the hedged item related to the designated risk being hedged, are reported in current earnings within derivative and other gains (losses). When assessing the effectiveness of our fair value hedges, we exclude the changes in fair value related to the difference between the spot and the forward rate on our foreign currency forwards and the time value of options.
Certain of our consolidated VIEs have foreign currency swaps that qualify for hedge accounting treatment. For those that have qualified, we have designated the derivative as a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset (“cash flow” hedge). We expect to continue this hedging activity for a weighted-average period of approximately 10 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 designate and account for certain foreign currency forwards and options as fair value hedges when they meet the requirements for hedge accounting. These foreign currency forwards and options hedge the foreign currency exposure of certain U.S. dollar-denominated fixed maturity securities within the investment portfolio of our Aflac Japan segment. We recognize gains and losses on these derivatives and the related hedged items in current earnings within derivative and other gains (losses). The change in the fair value of the foreign currency forwards related to the changes in the difference between the spot rate and the forward price is excluded from the assessment of hedge effectiveness. The change in fair value of the foreign currency option related to the time value of the option is excluded from the assessment of hedge effectiveness.
We designate and account for interest rate swaptions as fair value hedges when they meet the requirements for hedge accounting. These interest rate swaptions hedge the interest rate exposure of certain U.S. dollar-denominated fixed maturity securities within the investment portfolio of our Aflac Japan segment. We recognize gains and losses on these derivatives and the related hedged items in current earnings within derivative and other gains (losses). The change
Our primary exposure to be hedged is our net investment in Aflac Japan, which is affected by changes in the yen/dollar exchange rate. To mitigate this exposure, we have designated the Parent Company's yen-denominated liabilities (Samurai and Uridashi notes - see Note 9) as non-derivative hedges and designated foreign currency forwards and options as derivative hedges of the foreign currency exposure of our net investment in Aflac Japan.
We used foreign exchange forwards and options to hedge foreign exchange risk on 30.0 billion yen, 102.5 billion yen, 25.0 billion yen, and 85.0 billion yen of profit repatriation received from Aflac Japan in February 2015, July 2015, September 2015, and December 2015, respectively. As of December 31, 2015, we had entered into foreign exchange forwards and options as part of a hedge on 124.1 billion yen of future profit repatriation.
We have cross-currency interest rate swap agreements related to our $400 million senior notes due February 2017, $550 million senior notes due March 2020, $350 million senior notes due February 2022, $700 million senior notes due June
2023, $750 million senior notes due November 2024, $450 million senior notes due March 2025, and $500 million subordinated debentures due September 2052. Changes in the values of these swaps are recorded through current period earnings. For additional information regarding these swaps, see Note 9.
There was no gain or loss reclassified from accumulated other comprehensive income (loss) into earnings related to our designated cash flow hedges and net investment hedge for the years ended December 31, 2015, 2014 and 2013. As of December 31, 2015, deferred gains and losses on derivative instruments recorded in accumulated other comprehensive income that are expected to be reclassified to earnings during the next twelve months were immaterial.
We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities (see Note 3). When we have entered into securities lending agreements with the same counterparty, the agreements generally provide for net settlement in the event of default by the counterparty. This right of
The tables below summarize our derivatives and securities lending transactions as of December 31, and as reflected in the tables, in accordance with U.S. GAAP, our policy is to not offset these financial instruments in the Consolidated Balance Sheets.
(1) Consists of $153 of pledged securities and $466 of cash.
U.S. GAAP requires disclosure of the fair value of certain financial instruments including those that are not carried at fair value. The carrying amounts for cash and cash equivalents, other investments, receivables, accrued investment income, accounts payable, cash collateral and payables for security transactions approximated their fair values due to the nature of these instruments. Liabilities for future policy benefits and unpaid policy claims are not financial instruments as defined by U.S. GAAP.
The fair values of the foreign currency forwards, options, and interest rate swaptions associated with certain fixed-maturity securities; the foreign currency forwards and options used to hedge foreign exchange risk from our net investment in Aflac Japan and economically hedge certain portions of forecasted cash flows denominated in yen; and the foreign currency swaps associated with certain senior notes and our subordinated debentures are based on the amounts we would expect to receive or pay. The determination of the fair value of these derivatives is based on observable market inputs, therefore they are classified as Level 2.
The following tables summarize the significant unobservable inputs used in the valuation of our Level 3 available-for-sale investments and derivatives as of December 31. Included in the tables are the inputs or range of possible inputs that have an effect on the overall valuation of the financial instruments.
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.
Our remaining CDO is a tranche on a basket of single-name credit default swaps. The risk in this synthetic CDO comes 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 this tranche, the 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 the portfolio underlying the synthetic CDO to be valued, several processing steps are taken to map the CDO in our portfolio to the indices. With the base
The incurred claims development related to prior years reflects favorable claims experience compared to previous estimates, primarily in our lines of business in Japan.
Effective March 31, 2015, we entered into a coinsurance transaction whereby we ceded 30.0% of the sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business. In December 2015, we entered into an agreement for an $80 million letter of credit as collateral for this reinsurance transaction (see Note 13 for additional information). Effective April 1, 2015, we entered into a retrocession coinsurance transaction whereby we assumed 27.0% of the sickness hospital benefit of one of Aflac Japan’s closed in-force blocks of business through our subsidiary CAIC.
Effective October 1, 2014 and September 30, 2013, we entered into coinsurance reinsurance transactions whereby we ceded 16.7% and 33.3%, respectively, of the hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business. Effective December 31, 2014, we entered into a retrocession coinsurance reinsurance transaction whereby we assumed 8.35% of the reinsured hospital benefit of one of Aflac Japan’s closed medical in-force blocks of business through our subsidiary CAIC.
For our reinsurance transactions to date, we have recorded a deferred profit liability related to the reinsurance transactions. The remaining deferred profit liability of $786 million, as of December 31, 2015, included in future policy benefits in the consolidated balance sheet, is being amortized into income over the expected lives of the policies. We also have recorded a reinsurance recoverable for reinsurance transactions, which is included in other assets in the consolidated balance sheet and had a remaining balance of $805 million as of December 31, 2015.
As a part of our capital contingency plan, we entered into a committed reinsurance facility agreement on December 1, 2015 in the amount of approximately 110 billion yen. This reinsurance facility agreement is effective from December 1, 2015 until December 31, 2016. There are also additional commitment periods of a one-year duration each which are automatically extended unless notification is received from the reinsurer within 60 days prior to the expiration. The
reinsurer can withdraw from the committed facility if Aflac‘s Standard and Poor's (S&P) rating drops below BBB-. As of December 31, 2015, we have not executed a reinsurance treaty under this committed reinsurance facility.
In November 2014, the Parent Company issued $750 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 3.625% per annum, payable semi-annually, and have a ten-year maturity. These notes are redeemable at our option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the treasury rate plus 20 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date. We entered into cross-currency interest rate swaps to reduce interest expense by converting the U.S. dollar-denominated principal and interest on the
In June 2013, the Parent Company issued $700 million of senior notes through a U.S. public debt offering. The notes bear interest at a fixed rate of 3.625% per annum, payable semi-annually, and have a ten-year maturity. These notes are redeemable at our option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the aggregate principal amount of the notes to be redeemed or (ii) the amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the notes to be redeemed, not including any portion of the payments of interest accrued as of such redemption date, discounted to such redemption date on a semiannual basis at the treasury rate plus 20 basis points, plus in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to, but excluding, such redemption date. We entered into cross-currency interest rate swaps to reduce interest expense by converting the U.S. dollar-denominated principal and interest on the senior notes we issued into yen-denominated obligations. By entering into these swaps, we economically converted our $700 million liability into a 69.8 billion yen liability and reduced the interest rate on this debt from 3.625% in dollars to 1.50% in yen.
In September 2012, the Parent Company issued $450 million of subordinated debentures through a U.S. public debt offering. The debentures bear interest at a fixed rate of 5.50% per annum, payable quarterly, and have a 40-year maturity. In five years, on or after September 26, 2017, we may redeem the debentures, in whole or in part, at their principal amount plus accrued and unpaid interest to, but excluding, the date of redemption; provided that if the debentures are not redeemed in whole, at least $25 million aggregate principal amount of the debentures must remain outstanding after giving effect to such redemption. The debentures may only be redeemed prior to September 26, 2017, in whole but not in part, upon the occurrence of certain tax events or certain rating agency events, as specified in the indenture governing the terms of the debentures. We entered into cross-currency interest rate swaps to convert the U.S. dollar-denominated principal and interest on the subordinated debentures we issued into yen-denominated obligations. By entering into these swaps, we economically converted our $450 million liability into a 35.3 billion yen liability and reduced the interest rate on this debt from 5.50% in dollars to 4.41% in yen. The swaps will expire after the initial five-year non-callable period for the debentures. In October 2012, the underwriters exercised their option, pursuant to the underwriting agreement, to purchase an additional $50 million principal amount of the debentures discussed above. We entered into a cross-currency interest rate swap to economically convert this $50 million liability into a 3.9 billion yen liability and reduce the interest rate from 5.50% in dollars to 4.42% in yen. The swap will expire after the initial five-year non-callable period for the debentures.
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 semiannually, 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 semiannually, and has a ten-year maturity. These notes are redeemable at our option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the principal amount of the notes or (ii) the present value of the remaining scheduled payments of principal and interest to be redeemed, discounted to the redemption date, plus accrued and unpaid interest. We entered into cross-currency interest rate swaps to reduce interest expense by converting the U.S. dollar-denominated principal and interest on the senior notes we issued into yen-denominated obligations. By entering into these 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. We also 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. In July 2012, the Parent Company issued $250 million of senior notes that are an addition to the original first series of senior notes issued in February 2012. These notes have a five-year maturity and a fixed rate of 2.65% per annum, payable semiannually.
In July 2011, the Parent Company issued three series of Samurai notes totaling 50.0 billion yen through a public debt offering. The first series, which totaled 28.7 billion yen, and the third series, which totaled 5.5 billion yen, were redeemed in July 2014. The second series, which totaled 15.8 billion yen, bears interest at a fixed rate of 1.84% per annum, payable semiannually, and has a five-year maturity. These Samurai notes are not available to U.S. persons.
In 2010 and 2009, we issued senior notes through U.S. public debt offerings; the details of these notes are as follows. In August 2010, we issued $450 million and $300 million of senior notes that have 30-year and five-year maturities, respectively. In August 2015, we paid off the $300 million senior notes upon their maturity. In December 2009, we issued $400 million of senior notes that have a 30-year maturity. In May 2009, we issued $850 million of senior notes that had a ten-year maturity, and subsequently redeemed these notes in April 2015 using proceeds from the March 2015 issuance of fixed-rate senior notes. These senior notes pay interest semiannually and are redeemable at our option in whole at any time or in part from time to time at a redemption price equal to the greater of: (i) the principal amount of the notes or (ii)
the present value of the remaining scheduled payments of principal and interest to be redeemed, discounted to the redemption date, plus accrued and unpaid interest.
In September 2006, the Parent Company issued a tranche of Uridashi notes totaling 10 billion yen with a ten-year maturity. These Uridashi notes pay interest semiannually, may only be redeemed prior to maturity upon the occurrence of a tax event as specified in the respective bond agreement and are not available to U.S. persons. During 2009, we extinguished 2.0 billion yen (par value) of these Uridashi notes by buying the notes on the open market at a cost of 1.4 billion yen, yielding a gain of .6 billion yen.
In August 2015, we paid off a 5.0 billion yen loan at its maturity date (a total of approximately $41 million using the exchange rate at the maturity date). In July 2015, we paid off a 10.0 billion yen loan at its maturity date (a total of approximately $81 million using the exchange rate at the maturity date).
For our yen-denominated notes and loans, the principal amount as stated in dollar terms will fluctuate from period to period due to changes in the yen/dollar exchange rate. We have designated the majority of our yen-denominated notes payable as a nonderivative hedge of the foreign currency exposure of our investment in Aflac Japan.
The aggregate contractual maturities of notes payable during each of the years after December 31, 2015, are as follows:
In October 2015, the Parent Company and Aflac jointly entered into a 364 days uncommitted bilateral line of credit that provides for borrowings in the amount of $100 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expenses or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. Borrowings under the financing agreement will mature no later than three months after the last drawdown date of October 15, 2016. As of December 31, 2015, we did not have any borrowings outstanding under our $100 million credit agreement.
In September 2015, we amended and restated our 50.0 billion yen senior unsecured revolving credit facility agreement, due to expire in March 2018, pursuant to which the Parent Company and Aflac jointly entered into a new five-year senior unsecured revolving credit facility agreement with a syndicate of financial institutions that provides for borrowings of up to 55.0 billion yen or the equivalent of yen in U.S. dollars on a revolving basis. This credit agreement provides for borrowings in Japanese yen or the equivalent of Japanese yen in U.S. dollars on a revolving basis. Borrowings bear interest at a rate per annum equal to, at our option, either (a) a eurocurrency rate determined by reference to the London Interbank Offered Rate (LIBOR) for the interest period relevant to such borrowing adjusted for certain additional costs or (b) a base rate determined by reference to the highest of (1) the federal funds effective rate plus ½ of 1%, (2) the rate of interest for such day announced by Mizuho Bank, Ltd. as its prime rate and (3) the eurocurrency rate for an interest period of one month plus 1.00%, in each case plus an applicable margin. The applicable margin ranges between .79% and 1.275% for eurocurrency rate borrowings and 0.0% and .275% for base rate borrowings, depending on the Parent Company’s debt ratings as of the date of determination. In addition, the Parent Company and Aflac are required to pay a facility fee on the commitments ranging between .085% and .225%, also based on the Parent Company’s debt ratings as of the date of determination. Borrowings under the amended and restated credit facility may be used for general corporate purposes, including a capital contingency plan for the operations of the Parent Company and Aflac. The amended and restated credit facility requires compliance with certain financial covenants on a quarterly basis and will expire on the earlier of (a) September 18, 2020, or (b) the date the commitments are terminated pursuant to an event of default, as such term is defined in the credit agreement. As of December 31, 2015, we did not have any borrowings outstanding under our 55.0 billion yen revolving credit agreement.
In February 2015, the Parent Company and Aflac jointly entered into an uncommitted bilateral line of credit with a third party that provides for borrowings in the amount of $50 million. Borrowings will bear interest at the rate quoted by the bank and agreed upon at the time of making such loan and will have a three-month maturity period. There are no related facility fees, upfront expenses or financial covenant requirements. Borrowings under this credit agreement may be used for general corporate purposes. As of December 31, 2015, we did not have any borrowings outstanding under our $50 million credit agreement.
The tax effect on other comprehensive income (loss) shown in the table above included a deferred income tax expense of $614 million in 2013, related to certain U.S. dollar-denominated investments that Aflac Japan maintained on behalf of Aflac U.S. As discussed in Note 1, prior to October 1, 2013, there was no translation adjustment to record in pretax other comprehensive income for the portfolio when the yen/dollar exchange rate changed, however deferred tax expense or benefit associated with the foreign exchange translation gains or losses on these U.S. dollar-denominated investments is recognized in total income tax expense on other comprehensive income until the securities mature or are sold. Excluding the tax amounts for these U.S. dollar-denominated investments from total taxes on other comprehensive income would result in an effective income tax rate on pretax other comprehensive income (loss) of 31% in 2013.
Under U.S. income tax rules, only 35% of non-life operating losses can be offset against life insurance taxable income each year. For current U.S. income tax purposes, there were non-life operating loss carryforwards of $1 million expiring in 2035, and no tax credit carryforwards available at December 31, 2015. The Company did not have any capital loss carryforwards available to offset capital gains at December 31, 2015.
Included in the balance of the liability for unrecognized tax benefits at December 31, 2015, are $261 million of tax positions for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility, compared with $307 million at December 31, 2014. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate, but would accelerate the payment of cash to the taxing authority to an earlier period. The Company has accrued approximately $3 million as of December 31, 2015, for permanent uncertainties, which if reversed would not have a material effect on the annual effective rate.
The table below is a reconciliation of accumulated other comprehensive income by component for the years ended December 31.
As of December 31, 2015, the Company has outstanding share-based awards under two long-term incentive compensation plans.
The second long-term incentive compensation plan allows awards to Company employees for ISOs, NQSOs, restricted stock, restricted stock units, and stock appreciation rights. Non-employee directors are eligible for grants of NQSOs, restricted stock, and stock appreciation rights. The ISOs and NQSOs have a term of 10 years, and the share-based awards generally vest upon time-based conditions or time- and performance-based conditions. Time-based vesting generally occurs after three years. Performance-based vesting conditions generally include the attainment of goals related to Company financial performance. As of December 31, 2015, approximately 10.1 million shares were available for future grants under this plan, and the only performance-based awards issued and outstanding were restricted stock awards.
We estimate the fair value of each stock option granted using the Black-Scholes-Merton multiple option approach. Expected volatility is based on historical periods generally commensurate with the estimated terms of the options. We use historical data to estimate option exercise and termination patterns within the model. Separate groups of employees that have similar historical exercise patterns are stratified and considered separately for valuation purposes. The expected term of options granted is derived from the output of our option model and represents the weighted-average period of time that options granted are expected to be outstanding. We base the risk-free interest rate on the Treasury note rate with a term comparable to that of the estimated term of the options. The weighted-average fair value of options at their grant date was $9.46 per share for 2015, compared with $16.24 for 2014 and $14.25 in 2013. The following table presents the assumptions used in valuing options granted during the years ended December 31.
The aggregate intrinsic value represents the difference between the exercise price of the stock options and the quoted closing common stock price of $59.90 as of December 31, 2015, for those awards that have an exercise price currently below the closing price. As of December 31, 2015, the aggregate intrinsic value of stock options outstanding was $76 million, with a weighted-average remaining term of 4.5 years. The aggregate intrinsic value of stock options exercisable at that same date was $72 million, with a weighted-average remaining term of 3.3 years.
Aflac, the Company's most significant insurance subsidiary, reports statutory financial statements that are prepared on the basis of accounting practices prescribed or permitted by the Nebraska Department of Insurance (NEDOI). The NEDOI recognizes statutory accounting principles and practices prescribed or permitted by the state of Nebraska for determining and reporting the financial condition and results of operations of an insurance company, and for determining a company's solvency under Nebraska insurance law. The National Association of Insurance Commissioners' (NAIC) Accounting Practices and Procedures Manual (SAP) has been adopted by the state of Nebraska as a component of those prescribed or permitted practices. Additionally, the Director of the NEDOI has the right to permit other specific practices which deviate from prescribed practices. Aflac has been given explicit permission by the Director of the NEDOI for two such permitted practices. These permitted practices, which do not impact the calculation of net income on a statutory basis or prevent the triggering of a regulatory event in the Company's risk-based capital calculation, are as follows:
We entered into foreign exchange forwards and options as part of an economic hedge on foreign exchange risk on 242.5 billion yen of profit repatriation received in 2015, resulting in $71 million of additional funds received when the yen were exchanged into dollars. As of December 31, 2015, we had foreign exchange forwards and options as part of a hedging strategy on 124.1 billion yen of future profit repatriation.
We have funded defined benefit plans in Japan and the United States, which cover substantially all of our full-time employees. Additionally, we maintain non-qualified, unfunded supplemental retirement plans that provide defined pension benefits in excess of limits imposed by federal tax law for certain Japanese, U.S. and former employees. Effective October 1, 2013, the U.S. tax-qualified defined benefit plan was frozen to new employees hired on or after October 1, 2013 and to employees rehired on or after October 1, 2013. U.S. employees who are not participants in the defined benefit plan receive a nonelective 401(k) employer contribution. Additionally, effective January 1, 2015, the U.S. non-qualified supplemental retirement plan was frozen to new participants.
participant salary and future salary increases are not factors in determining pension benefit cost or the related pension benefit obligation.
Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plan. A one-percentage point increase and decrease in assumed health care cost trend rates would have the following effects as of December 31, 2015:
Aflac U.S. maintains a stock bonus plan for eligible U.S. sales associates. Plan participants receive shares of Aflac Incorporated common stock based on their new annualized premium sales and their first-year persistency of substantially all new insurance policies. The cost of this plan, which was capitalized as deferred policy acquisition costs, amounted to $34 million in 2015, compared with $36 million in 2014 and $38 million in 2013.
We have an outsourcing agreement with a management consulting and technology services company to provide application maintenance and development services for our Japanese operation. The agreement has a remaining term of two years with an aggregate remaining cost of 3.1 billion yen ($26 million using the December 31, 2015, exchange rate).
