The methods and assumptions used to estimate the fair value of the Company’s financial assets and liabilities carried at fair value on a recurring basis are as follows:

Fixed maturity investments

The fair values for fixed maturity investments are based upon market prices from independent pricing services. In cases where market prices are not readily available, fair values are estimated by the Company. To determine estimated fair value for these instruments, the Company generally utilizes discounted cash flows models with market observable pricing inputs such as spreads, average life, and credit quality. Fair value estimates are made at a specific point in time, based on available market information and judgments about financial instruments, including estimates of the timing and amounts of expected future cash flows and the credit standing of the issuer or counterparty.

Short-term investments and securities lending agreements

The amortized cost of short-term investments, collateral under securities lending agreements, and payable under securities lending agreements is a reasonable estimate of fair value due to their short-term nature and high credit quality of the issuers.

Derivative counterparty collateral agreements

Included in other assets is cash collateral received from or pledged to derivative counterparties and included in other liabilities is the obligation to return the cash collateral to the counterparties. The carrying value of the collateral is a reasonable estimate of fair value.

Derivative instruments

Included in other assets and other liabilities are derivative financial instruments. The estimated fair values of OTC derivatives, primarily consisting of cross-currency swaps, interest rate swaps, interest rate swaptions, and other forward contracts, are the estimated amounts the Company would receive or pay to terminate the agreements at the end of each reporting period, taking into consideration current interest rates and other relevant factors.

Embedded derivative - GLWB

Significant unobservable inputs used in the fair value measurements of GLWB include long-term equity and interest rate implied volatility, mortality, and policyholder behavior assumptions, such as benefit utilization, lapses, and partial withdrawals.

Separate account assets and liabilities

Separate account assets and liabilities primarily include investments in mutual fund, fixed maturity, and short-term securities. Mutual funds are recorded at net asset value, which approximates fair value, on a daily basis. The fixed maturity and short-term investments are valued in the same manner, and using the same pricing sources and inputs as the fixed maturity and short-term investments of the Company.

Non-recurring fair value measurements - Certain assets are measured at estimated fair value on a non-recurring basis and are not included in the tables above. The Company held zero and $9,242 of adjusted cost basis limited partnership interests which were impaired at June 30, 2015, and December 31, 2014, respectively, based on the fair value disclosed in the limited partnership financial statements. These limited partnership interests were recorded at estimated fair value and represent a non-recurring fair value measurement. The estimated fair value was categorized as Level 3.

The methods and assumptions used to estimate the fair value of financial instruments not carried at fair value on a recurring basis are summarized as follows:

Mortgage loans on real estate

Mortgage loan fair value estimates are generally based on discounted cash flows. A discount rate matrix is used where the discount rate valuing a specific mortgage generally corresponds to that mortgage’s remaining term and credit quality. Management believes the discount rate used is comparable to the credit, interest rate, term, servicing costs, and risks of loans similar to the portfolio loans that the Company would make today given its internal pricing strategy. The estimated fair value is classified as Level 2.

Policy loans

Policy loans are funds provided to policy holders in return for a claim on the policy. The funds provided are limited to the cash surrender value of the underlying policy. The nature of policy loans is to have a negligible default risk as the loans are fully collateralized by the value of the policy. Policy loans do not have a stated maturity and the balances and accrued interest are repaid either by the policyholder or with proceeds from the policy. Due to the collateralized nature of policy loans and unpredictable timing of repayments, the Company believes the fair value of policy loans approximates carrying value. The estimated fair value is classified as Level 2.

Limited partnership interests

Limited partnership interests, accounted for using the cost method, represent the Company’s minority ownership interests in pooled investment funds. These funds employ varying investment strategies that principally make private equity investments across diverse industries and geographical focuses. The estimated fair value was determined using the partnership financial statement reported capital account or net asset value adjusted for other relevant information which may impact the exit value of the investments. Distributions by these investments are generated from investment gains, from operating income generated by the underlying investments of the funds, and from liquidation of the underlying assets of the funds which are estimated to be liquidated over the next one to 10 years. The estimated fair value is classified as Level 3.

Other investments

Other investments primarily include real estate held for investment. The estimated fair value for real estate is based on the unadjusted annual appraised value which includes factors such as comparable property sales, property income analysis, and capitalization rates. The estimated fair value is classified as Level 2.

Annuity contract benefits without life contingencies

The estimated fair value of annuity contract benefits without life contingencies is estimated by discounting the projected expected cash flows to the maturity of the contracts utilizing risk-free spot interest rates plus a provision for the Company’s credit risk. The estimated fair value is classified as Level 2.

Policyholders’ funds

The carrying amount of policyholders’ funds approximates the fair value since the Company can change the interest credited rates with 30 days notice. The estimated fair value is classified as Level 2.

Commercial paper

The amortized cost of commercial paper is a reasonable estimate of fair value due to its short-term nature and the high credit quality of the obligor. The estimated fair value is classified as Level 2.

Notes payable

The estimated fair value of the notes payable to GWL&A Financial is based upon quoted market prices from independent pricing services of securities with characteristics similar to those of the notes payable. The estimated fair value is classified as Level 2.
