Investments, Debt and Equity Securities [Abstract]

NOTE 3. INVESTMENT SECURITIES. All of our debt securities are classified as available-for-sale and substantially all are investment-grade debt securities supporting obligations to annuitants and policyholders in our run-off insurance operations. Changes in fair value of our debt securities are recorded in Other comprehensive income. Equity securities with readily determinable fair values are included within this caption and changes in their fair value are recorded in earnings.

The amortized cost of debt securities as of September 30, 2020, excludes accrued interest of $442 million, which is reported in Other GE Capital receivables.

The estimated fair values of investment securities at September 30, 2020 decreased since December 31, 2019, primarily due to the mark-to-market effects on our remaining interest in BKR, partially offset by a decrease in market yields and new investments in our insurance business. The fair value of the remaining BKR interest and promissory note receivable was $5,102 million at September 30, 2020.

Gross unrealized losses of $(169) million and $(33) million are associated with debt securities with a fair value of $2,413 million and $153 million that have been in a loss position for less than 12 months and 12 months or more, respectively, at September 30, 2020. Gross unrealized losses of $(11) million and $(20) million are associated with debt securities with a fair value of $724 million and $274 million that have been in a loss position for less than 12 months and 12 months or more, respectively, at December 31, 2019.

As of September 30, 2020, gross unrealized losses of $(202) million included $(83) million related to U.S. corporate securities, primarily in the energy industry, and $(87) million related to commercial mortgage-backed securities (CMBS). Substantially all of our CMBS in an unrealized loss position have received investment-grade credit ratings from the major rating agencies and are collateralized by pools of commercial mortgage loans on real estate.

Net unrealized gains (losses) for equity securities with readily determinable fair values, which are recorded in Other income within continuing operations, were $(776) million and $(89) million for the three months ended and $(4,619) million and $(131) million for the nine months ended September 30, 2020 and 2019, respectively.

Proceeds from debt and equity securities sales, early redemptions by issuers and principal payments on the BKR promissory note totaled $833 million and $2,318 million for the three months ended and $3,538 million and $6,652 million for the nine months ended September 30, 2020 and 2019, respectively. Gross realized gains on investment securities were $17 million and $10 million for the three months ended and $145 million and $86 million for the nine months ended September 30, 2020 and 2019, respectively. Gross realized losses and impairments were $(10) million and $(75) million for the three months ended and $(95) million and $(181) million for the nine months ended September 30, 2020 and 2019, respectively.

Contractual maturities of investments in debt securities (excluding mortgage and asset-backed securities) as of September 30, 2020 are due as follows:


(In millions)	Amortized cost		Estimated fair value

Within one year	$	673	$	684
After one year through five years	2,568		2,799
After five years through ten years	6,516		7,732
After ten years	20,771		26,739

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

Substantially all our equity securities are classified within Level 1 and substantially all our debt securities are classified within Level 2, as their valuation is determined based on significant observable inputs. Investments with a fair value of $5,548 million and $5,210 million are classified within Level 3, as significant inputs to the valuation model are unobservable at September 30, 2020 and December 31, 2019, respectively. During the nine months ended September 30, 2020 and 2019, there were no significant transfers into or out of Level 3.

In addition to the equity securities described above, we hold $258 million and $517 million of equity securities without readily determinable fair value at September 30, 2020 and December 31, 2019, respectively, that are classified within All other assets in our consolidated Statement of Financial Position. Fair value adjustments, including impairments, recorded in earnings were both insignificant amounts for the three months ended and $(163) million and $25 million for the nine months ended September 30, 2020 and 2019, respectively.
