Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Asset-backed, commercial mortgage-backed and residential mortgage-backed securities are shown separately in the table above, as they are not due at a single maturity date.

The following table depicts the sources of fixed maturity and equity security proceeds and related investment gains (losses), as well as losses on impairments of both fixed maturities and equity securities:

Excludes the portion of OTTI recorded in “Other comprehensive income (loss),” representing any difference between the fair value of the impaired debt security and the net present value of its projected future cash flows at the time of the impairment.

As discussed in Note 2 to the Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, a portion of certain OTTI losses on fixed maturity securities is recognized in “Other comprehensive income (loss)" (“OCI”). For these securities, the net amount recognized in earnings (“credit loss impairments”) represents the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. Any remaining difference between the fair value and amortized cost is recognized in OCI. The following table sets forth the amount of pre-tax credit loss impairments on fixed maturity securities held by the Company as of the dates indicated, for which a portion of the OTTI loss was recognized in OCI, and the corresponding changes in such amounts.

See Note 2 to the Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015 for further discussion regarding non-accrual status loans.

For the three months ended March 31, 2016 and 2015, there were no commercial mortgage and other loans acquired, other than those through direct origination, nor were there any commercial mortgage and other loans sold.

The Company’s commercial mortgage and other loans may occasionally be involved in a troubled debt restructuring.

The gross unrealized losses on fixed maturity securities as of March 31, 2016 and December 31, 2015, are composed of $12.6 million and $22.6 million, respectively, related to high or highest quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $13.8 million and $12.1 million, respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of March 31, 2016, the $12.3 million of gross unrealized losses of twelve months or more were concentrated in the consumer non-cyclical, capital goods, finance and utility sectors of the Company’s corporate securities. As of December 31, 2015, the $18.8 million of gross unrealized losses of twelve months or more were concentrated in consumer non-cyclical, capital goods, utility and finance sectors of the Company’s corporate securities. In accordance with its policy described in Note 2 to the Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, the Company concluded that an adjustment to earnings for OTTI for these securities was not warranted at March 31, 2016 or December 31, 2015. These conclusions are based on a detailed analysis of the underlying credit and cash flows on each security. The gross unrealized losses are primarily attributable to a decrease in interest rates, general credit spread tightening and foreign currency exchange rate movements. As of March 31, 2016, the Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell these securities before the anticipated recovery of the remaining amortized cost basis.

Securities Lending and Repurchase Agreements

In the normal course of business, the Company sells securities under agreements to repurchase and enters into securities lending transactions. As of March 31, 2016 and December 31, 2015, the Company had $3.7 million and $10.6 million, respectively, of securities lending transactions recorded as "Cash collateral for loaned securities," all of which were corporate securities. The remaining contractual maturity of all securities lending transactions is overnight and continuous. As of both March 31, 2016 and December 31, 2015, the Company had no repurchase transactions.
