⁽¹⁾	Fair value includes securities issued by Federal National Mortgage Association (FNMA) of $370,182 thousand and $441,308 thousand; Federal Home Loan Mortgage Corporation (FHLMC) of $256,531 thousand and $417,308 thousand; and Government National Mortgage Association (GNMA) of $79,141 thousand and $96,466 thousand as of June 30, 2019 and December 31, 2018, respectively.

The following table presents the fair value and gross unrealized losses of securities in an unrealized loss position at June 30, 2019 and December 31, 2018, respectively. The Company views the decrease in fair value of all of the securities with unrealized losses at June 30, 2019 -- which was driven largely by increasing interest rates, spread widening, financial market illiquidity and/or market volatility from the date of acquisition -- as temporary. For fixed maturity securities, management does not have the intent to sell the securities and it is not more likely than not the Company will be required to sell the securities before the anticipated recovery of their amortized cost bases, and management expects to recover the entire amortized cost bases of the fixed maturity securities. Therefore, it was determined that the unrealized losses on the securities presented in the table below were not other-than-temporarily impaired as of June 30, 2019.

Fixed maturity securities with an investment grade rating represented 84.0% of the gross unrealized losses as of June 30, 2019. With respect to fixed maturity securities involving securitized financial assets, the underlying collateral cash flows were stress tested to determine there was no adverse change in the present value of cash flows below their amortized cost bases.

Limited Partnership Interests

As of June 30, 2019 and December 31, 2018, the carrying value of equity method limited partnerships totaled $351,515 thousand and $328,516 thousand, respectively. Principal factors influencing carrying value appreciation or decline include operating performance, comparable public company earnings multiples, capitalization rates and the economic environment. The Company recognizes an impairment loss for equity method limited partnerships when evidence demonstrates that the loss is other than temporary. Evidence of a loss in value that is other than temporary may include the absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain a level of earnings that would justify the carrying amount of the investment.

Credit Losses

The following table summarizes the cumulative amounts related to the Company’s credit loss component of other-than-temporary impairment (OTTI) losses on fixed maturity securities held as of June 30, 2019 and 2018 that the Company did not intend to sell as of those dates, and it was not more likely than not that the Company would be required to sell the securities before the anticipated recovery of the amortized cost bases, for which the non-credit portions of OTTI losses were recognized in OCI:

⁽¹⁾	The cumulative credit loss amounts exclude OTTI losses on securities held as of the periods indicated that the Company intended to sell or it was more likely than not that the Company would be required to sell the security before the recovery of the amortized cost basis.

Maturities of Fixed Maturity Securities

The following table presents the distribution of the Company’s fixed maturity securities portfolio by estimated expected maturity. Estimated expected maturities differ from contractual maturities, reflecting assumptions regarding borrowers’ utilization of the right to call or prepay obligations with or without call or prepayment penalties. For structured securities, including mortgage-backed securities and other asset-backed securities, estimated expected maturities consider broker-dealer survey prepayment assumptions and are verified for consistency with the interest rate and economic environments.
