The net unrealized gains on investments included in the tables above are recorded as a component of Accumulated other comprehensive income (AOCI). When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. To the extent that unrealized gains on fixed income securities supporting certain products within the Life & Group Non-Core segment would result in a premium deficiency if realized, a related increase in Insurance reserves is recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (loss) (Shadow Adjustments). As of March 31, 2016 and December 31, 2015, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $1,311 million and $1,111 million.

The following tables present the estimated fair value and gross unrealized losses of fixed maturity and equity securities in a gross unrealized loss position by the length of time in which the securities have continuously been in that position.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the March 31, 2016 table above, are not indicative of the ultimate collectibility of the current amortized cost of the securities, but rather are attributable to changes in interest rates, credit spreads and other factors, including volatility in the energy and metals and mining sectors. As of March 31, 2016, the Company held fixed maturity securities and equity securities with an estimated fair value of $2,446 million and a cost or amortized cost of $2,464 million in the energy and metals and mining sectors. The portion of these securities in a gross unrealized loss position had an estimated fair value of $1,069 million and a cost or amortized cost of $1,202 million. The Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional OTTI losses to be recorded as of March 31, 2016.

The following table presents the activity related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held as of March 31, 2016 and 2015 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).
