(a) Includes the estimated fair value of and gross unrealized losses on Corporate-non-U.S. and Equity securities held by GE. At March 31, 2014, the estimated fair value of and gross unrealized losses on Corporate-non-U.S. securities were $13 million and an insignificant amount, respectively. The estimated fair value of and gross unrealized losses on Equity securities were $210 million and $(70) million, respectively. At December 31, 2013, the estimated fair value of and gross unrealized losses on Corporate-non-U.S. securities were $12 million and $(1) million, respectively. The estimated fair value of and gross unrealized losses on Equity securities were $222 million and $(41) million, respectively.

(b) Includes gross unrealized losses related to securities that had other-than-temporary impairments previously recognized of $(85) million at March 31, 2014.

(c) The majority relate to debt securities held to support obligations to holders of GICs and more than 70% are debt securities that were considered to be investment-grade by the major rating agencies at March 31, 2014.

We regularly review investment securities for other-than-temporary impairment (OTTI) using both qualitative and quantitative criteria. For debt securities, our qualitative review considers our ability and intent to hold the security and the financial condition of and near-term prospects for the issuer, including whether the issuer is in compliance with the terms and covenants of the security. Our quantitative review considers whether there has been an adverse change in expected future cash flows. Unrealized losses are not indicative of the amount of credit loss that would be recognized and at March 31, 2014 are primarily due to increases in market yields subsequent to our purchase of the securities. We presently do not intend to sell the vast majority of our debt securities that are in an unrealized loss position and believe that it is not more likely than not that we will be required to sell the vast majority of these securities before anticipated recovery of our amortized cost. The methodologies and significant inputs used to measure the amount of credit loss for our investment securities during the three months ended March 31, 2014 have not changed. For equity securities, we consider the duration and the severity of the unrealized loss. We believe that the unrealized loss associated with our equity securities will be recovered within the foreseeable future.

Our corporate debt portfolio comprises securities issued by public and private corporations in various industries, primarily in the U.S. Substantially all of our corporate debt securities are rated investment grade by the major rating agencies.

Our RMBS portfolio is collateralized primarily by pools of individual, direct mortgage loans, of which substantially all are in a senior position in the capital structure of the deals, not other structured products such as collateralized debt obligations. Of the total RMBS held at March 31, 2014, $1,225 million and $649 million related to agency and non-agency securities, respectively. Additionally, $355 million was related to residential subprime credit securities, primarily supporting our guaranteed investment contracts. Substantially all of the subprime exposure is related to securities backed by mortgage loans originated in 2006 and prior. A majority of subprime RMBS have been downgraded to below investment grade and are insured by Monoline insurers (Monolines). We continue to place partial reliance on Monolines with adequate capital and claims paying resources depending on the extent of the Monoline's anticipated ability to cover expected credit losses.

Our commercial mortgage-backed securities (CMBS) portfolio is collateralized by both diversified pools of mortgages that were originated for securitization (conduit CMBS) and pools of large loans backed by high-quality properties (large loan CMBS), a majority of which were originated in 2007 and prior. The vast majority of the securities in our CMBS portfolio have investment-grade credit ratings.

Our asset-backed securities (ABS) portfolio is collateralized by senior secured loans of high-quality, middle-market companies in a variety of industries, as well as a variety of diversified pools of assets such as student loans and credit cards. The vast majority of the securities in our ABS portfolio are in a senior position in the capital structure of the deals.

(a) Included pre-tax, other-than-temporary impairments recorded in earnings related to equity securities of $1 million during both the three months ended March 31, 2014 and 2013.

We expect actual maturities to differ from contractual maturities because borrowers have the right to call or prepay certain obligations.

Although we generally do not have the intent to sell any specific securities at the end of the period, in the ordinary course of managing our investment securities portfolio, we may sell securities prior to their maturities for a variety of reasons, including diversification, credit quality, yield and liquidity requirements and the funding of claims and obligations to policyholders. In some of our bank subsidiaries, we maintain a certain level of purchases and sales volume principally of non-U.S. government debt securities. In these situations, fair value approximates carrying value for these securities.

Proceeds from investment securities sales and early redemptions by issuers totaled $1,349 million for the three months ended March 31, 2014, principally from sales of short-term government securities in our bank subsidiaries and Treasury operations and redemptions of non–U.S. corporate and asset-backed securities in our CLL business.

Proceeds from investment securities sales and early redemptions by issuers totaled $7,654 million for the three months ended March 31, 2013, principally from the sale of Comcast guaranteed debt, sales of short-term securities in our bank subsidiaries and Treasury operations and redemptions of non–U.S. corporate and asset-backed securities in our CLL business.

We recognized pre-tax gains (losses) on trading securities of $(5) million and $42 million in the three months ended March 31, 2014 and 2013, respectively.
