Derivative Financial Instruments

Derivative transactions are generally entered into pursuant to International Swaps and Derivatives Association (“ISDA”) Master Agreements or Master Securities Forward Transaction Agreements (“MSFTA”) with approved counterparties that provide for a single net payment to be made by one party to the other on a daily basis, periodic payment dates, or at the due date, expiration, or termination of the agreement.

The ISDA Master Agreements contain provisions that would allow the counterparties to require immediate settlement of all derivative instruments in a net liability position if the Company were to default on any debt obligations over a certain threshold. The MSFTA contain provisions which do not stipulate a threshold for default and only apply to debt obligations between the Company and the specific counterparty. The aggregate fair value, inclusive of accrued income and expense, of derivative instruments with credit-risk-related contingent features that were in a net liability position was $58,305 and $38,324 as of June 30, 2017, and December 31, 2016, respectively. The Company had pledged collateral related to these derivatives of $910 and zero as of June 30, 2017, and December 31, 2016, respectively, in the normal course of business. If the credit-risk-related contingent features were triggered on June 30, 2017, the fair value of assets that could be required to settle the derivatives in a net liability position was $57,395.

At June 30, 2017, and December 31, 2016, the Company had pledged $910 and zero of unrestricted cash collateral to counterparties in the normal course of business, while other counterparties had pledged $60,919 and $103,214 of unrestricted cash collateral to the Company to satisfy collateral netting agreements, respectively.

At June 30, 2017, the Company estimated $10,378 of net derivative gains related to cash flow hedges included in AOCI will be reclassified into net income within the next twelve months. Gains and losses included in AOCI are reclassified into net income when the hedged item affects earnings.

Types of derivative instruments and derivative strategies

Interest rate contracts

Cash flow hedges

Interest rate swap agreements are used to convert the interest rate on certain debt security investments and debt obligations from a floating rate to a fixed rate. Interest rate futures are used to manage the interest rate risks of forecasted acquisitions of fixed rate maturity investments and are primarily structured to hedge interest rate risk inherent in the assumptions used to price certain liabilities.

Not designated as hedging instruments

The Company enters into certain transactions in which derivatives are hedging an economic risk but hedge accounting is not elected. These derivative instruments include: exchange-traded interest rate swap futures, over-the-counter (“OTC”) interest rate swaptions, OTC interest rate swaps, exchange-traded Eurodollar interest rate futures, and treasury interest rate futures. Certain of the Company’s OTC derivatives are cleared and settled through a central clearing counterparty while others are bilateral contracts between the Company and a counterparty.

The derivative instruments mentioned above are economic hedges and used to manage risk. These transactions are used to offset changes in liabilities including those in variable annuity products, hedge the economic effect of a large increase in interest rates, manage the potential variability in future interest payments due to a change in credited interest rates and the related change in cash flows due to increased surrenders, and manage interest rate risks of forecasted acquisitions of fixed rate maturity investments and forecasted liability pricing.

Foreign currency contracts

Cross-currency swaps and foreign currency forwards are used to manage the foreign currency exchange rate risk associated with investments denominated in other than U.S. dollars. The Company uses cross-currency swaps to convert interest and principal payments on foreign denominated debt instruments into U.S. dollars. Cross-currency swaps may be designated as cash flow hedges; however, hedge accounting is not always elected. The Company uses foreign currency forwards to reduce the risk of foreign currency exchange rate changes on proceeds received on sales of foreign denominated debt instruments; however, hedge accounting is not elected.

Equity contracts

The Company uses futures on equity indices to offset changes in guaranteed lifetime withdrawal benefit liabilities; however, hedge accounting is not elected.

Other forward contracts

The Company uses forward settling to be announced (“TBA”) securities to gain exposure to the investment risk and return of agency mortgage-backed securities (pass-throughs). These transactions enhance the return on the Company’s investment portfolio and provide a more liquid and cost effective method of achieving these goals than purchasing or selling individual agency mortgage-backed pools. As the Company does not regularly accept delivery of such securities, they are accounted for as derivatives but hedge accounting is not elected.

Notional amounts are used to express the extent of the Company’s involvement in derivative transactions and represent a standard measurement of the volume of its derivative activity. Notional amounts represent those amounts used to calculate contractual flows to be exchanged and are not paid or received. The average notional outstanding during the six months ended June 30, 2017, was $901,471, $1,274,171, $114,737, $162,401, and $2,102,629 for interest rate swaps, cross-currency swaps, futures, swaptions, and other forward contracts, respectively. The average notional outstanding during the year ended December 31, 2016, was $784,900, $1,141,967, $145,658, $156,632, and $2,230,167 for interest rate swaps, cross-currency swaps, futures, swaptions, and other forward contracts, respectively.

Embedded derivative - Guaranteed Lifetime Withdrawal Benefit

The Company offers a guaranteed lifetime withdrawal benefit (“GLWB”) through a variable annuity or a contingent deferred annuity. The GLWB is deemed to be an embedded derivative. The GLWB is recorded at fair value within future policy benefits on the condensed consolidated balance sheets. Changes in fair value of GLWB are recorded in net investment income in the condensed consolidated statements of income.

The estimated fair value of the GLWB was $9,595 and $5,712 at June 30, 2017, and December 31, 2016, respectively. The changes in fair value of the GLWB were $(5,553) and $(8,980) for the three months ended June 30, 2017, and 2016, respectively, and $(3,883) and $(19,430) for the six months ended June 30, 2017, and 2016, respectively.
