a) | Fixed Maturities and Other Investments
During the second quarter of 2017, we designated additional fixed maturities with a fair value of $391,934 as held-to-maturity ("HTM") and during 2016 we designated fixed maturities with a total fair value of $155,538 as HTM reflecting our intent to hold these securities to maturity. The net unrealized holding gain of $4,313 and $15,770, respectively, as at each 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 yield 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 fixed maturities and other investments at September 30, 2017 and December 31, 2016, are as follows:

At December 31, 2016, there were approximately 251 securities in an unrealized loss position with a fair value of $2,106,048 and unrealized losses of $87,182. Of these securities, there were 91 securities that have been in an unrealized loss position for 12 months or greater with a fair value of $431,159 and unrealized losses of $57,444. OTTI The Company performs quarterly reviews of its fixed maturities in order to determine whether declines in fair value below the amortized cost basis were considered other-than-temporary in accordance with applicable guidance. At September 30, 2017, we have determined that the unrealized losses on fixed maturities were primarily due to widening of credit and interest rate spreads as well as the impact of foreign exchange rate changes on certain foreign currency denominated AFS fixed maturities since their date of purchase. Because we do not intend to sell these securities and it is not more likely than not that we will be required to do so until a recovery of fair value to amortized cost, we currently believe it is probable that we will collect all amounts due according to their respective contractual terms. Therefore, we do not consider these fixed maturities to be other-than-temporarily impaired ("OTTI") at September 30, 2017. The Company has recognized no OTTI through earnings for the three and nine months ended September 30, 2017 and 2016. The following summarizes the credit ratings of our fixed maturities:
