Investments | Investments (a) Fixed Maturities and Other Investments During the third quarter of 2015, we designated fixed maturities with a total fair value of $608,722 as HTM reflecting our intent to hold these securities to maturity. The net unrealized holding gain at the designation date continues to be reported in the carrying value of the HTM securities and is amortized through Other Comprehensive Income over the remaining life of the securities using the effective interest method in a manner consistent with the amortization of any premium or discount. The original or amortized cost, estimated fair value and gross unrealized gains and losses of investment in fixed maturities and other investments as of September 30, 2015 and December 31, 2014 are as follows: September 30, 2015 Original or Gross Gross Fair value AFS fixed maturities: U.S. treasury bonds $ 6,654 $ 405 $ (3 ) $ 7,056 U.S. agency bonds – mortgage-backed 1,302,878 24,516 (3,892 ) 1,323,502 U.S. agency bonds – other 28,705 739 — 29,444 Non-U.S. government and supranational bonds 33,650 — (4,142 ) 29,508 Commercial mortgage-backed securities 123,944 3,203 (6 ) 127,141 Collateralized loan obligations 53,411 49 (341 ) 53,119 Corporate bonds 1,679,952 46,375 (73,507 ) 1,652,820 Municipal bonds 62,171 3,749 — 65,920 Total AFS fixed maturities 3,291,365 79,036 (81,891 ) 3,288,510 HTM fixed maturities: Corporate bonds 608,510 5,181 (2,697 ) 610,994 Total HTM fixed maturities 608,510 5,181 (2,697 ) 610,994 Other investments 10,725 1,072 (325 ) 11,472 Total investments $ 3,910,600 $ 85,289 $ (84,913 ) $ 3,910,976 4.

Other-Than-Temporary Impairments ("OTTI") The Company performs quarterly reviews of its investment portfolio in order to determine whether declines in fair value below the amortized cost basis were considered other-than-temporary in accordance with applicable guidance. OTTI is required to be recorded in net income if management has the intent to sell the security or it is more likely than not that we will be required to sell the security before the recovery of its amortized cost. Further, in cases where we do not intend to sell the security and it is more likely than not that we will not be required to sell the security the Company must evaluate the security to determine the portion of the impairment, if any, related to credit losses. If a credit loss is determined, an OTTI is considered to have occurred and any portion of the OTTI related to credit losses must be reflected in net income. Based on our qualitative and quantitative OTTI review of each security within our fixed maturity portfolio, at September 30, 2015 , we have determined that there was a credit impairment in respect of one corporate bond. For the three and nine months ended September 30, 2015 and 2014 , the Company recognized $1,060 and $1,189 of OTTI, respectively. 4.
