__________ 
(1)
Includes $12 million of fair value and less than $1 million of gross unrealized losses, which are not reflected in AOCI, on securities classified as held-to-maturity, as of December 31, 2016.

As of December 31, 2017 and 2016, the gross unrealized losses on fixed maturity securities were composed of $1,470 million and $4,233 million, respectively, related to “1” highest quality or “2” high quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $306 million and $392 million, respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of December 31, 2017, the $1,443 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in U.S. government bonds, foreign government bonds and in the Company’s corporate securities within the energy, utility and consumer non-cyclical sectors. As of December 31, 2016, the $1,420 million of gross unrealized losses on fixed maturity securities of twelve months or more were concentrated in the Company’s corporate securities within the energy, utility and capital goods sectors. In accordance with its policy described in Note 2, the Company concluded that an adjustment to earnings for OTTI for these fixed maturity securities was not warranted at either December 31, 2017 or 2016. These conclusions were based on a detailed analysis of the underlying credit and cash flows on each security. Gross unrealized losses are primarily attributable to general credit spread widening, increases in interest rates and foreign currency exchange rate movements. As of December 31, 2017, the Company did not intend to sell these securities, and it was not more likely than not that the Company would be required to sell these securities before the anticipated recovery of the remaining amortized cost basis.
 
As of December 31, 2017, $8 million of the gross unrealized losses on equity securities represented declines in value of 20% or more, $5 million of which had been in a gross unrealized loss position for less than six months. As of December 31, 2016, $9 million of the gross unrealized losses on equity securities represented declines in value of 20% or more, $8 million of which had been in a gross unrealized loss position for less than six months. In accordance with its policy described in Note 2, the Company concluded that an adjustment to earnings for OTTI for these equity securities was not warranted at either December 31, 2017 or 2016.

For additional information regarding the Company’s holdings in the Federal Home Loan Banks of New York and Boston, see Note 14.
 
In certain investment structures, the Company’s investment management business invests with other co-investors in an investment fund referred to as a feeder fund. In these structures, the invested capital of several feeder funds is pooled together and used to purchase ownership interests in another fund, referred to as a master fund. The master fund utilizes this invested capital and, in certain cases, other debt financing, to purchase various classes of assets on behalf of its investors. Specialized industry accounting for investment companies calls for the feeder fund to reflect its investment in the master fund as a single net asset equal to its proportionate share of the net assets of the master fund, regardless of its level of interest in the master fund. In cases where the Company consolidates the feeder fund, it retains the feeder fund’s net asset presentation and reports the consolidated feeder fund’s proportionate share of the net assets of the master fund in “Other long-term investments,” with any unaffiliated investors’ non-controlling interest in the feeder fund reported in “Other liabilities” or “Noncontrolling interests.” The consolidated feeder funds’ investments in these master funds, reflected on this net asset basis, totaled $451 million and $216 million as of December 31, 2017 and 2016, respectively. There was $310 million and $93 million of unaffiliated interest in the consolidated feeder funds as of December 31, 2017 and 2016, respectively, and the master funds had gross assets of $82,126 million and $36,279 million, respectively, and gross liabilities of $79,185 million and $34,880 million, respectively, which are not included on the Company’s balance sheet.

In the normal course of its business activities, the Company accepts collateral that can be sold or repledged. The primary sources of this collateral are securities in customer accounts, securities purchased under agreements to resell and postings of collateral from OTC derivative counterparties. The fair value of this collateral was approximately $5,126 million as of December 31, 2017 (the largest components of which include $599 million of securities and $4,527 million of cash from OTC derivative counterparties) and $7,185 million as of December 31, 2016 (the largest components of which include $1,595 million of securities and $5,590 million of cash from OTC derivative counterparties). A portion of the aforementioned securities, for both periods, had either been sold or repledged.

Assets of $73 million and $78 million at December 31, 2017 and 2016, respectively, were on deposit with governmental authorities or trustees, including certain restricted cash balances and securities. Restricted cash and securities of $45 million and $54 million at December 31, 2017 and 2016, respectively, were included in “Other assets.” Additionally, assets carried at $3.5 billion and $3.3 billion at December 31, 2017 and 2016, respectively, were held in a trust established for the benefit of certain policyholders related to a reinsurance agreement between two wholly-owned subsidiaries. Assets carried at $604 million and $605 million at December 31, 2017 and 2016, respectively, were held in voluntary trusts established primarily to fund guaranteed dividends to certain policyholders and to fund certain employee benefits. Securities restricted as to sale amounted to $59 million and $89 million as of December 31, 2017 and 2016, respectively. These amounts include member and activity-based stock associated with memberships in the Federal Home Loan Banks of New York and Boston.
