The following table summarizes the gross proceeds, gross realized gains, and gross realized losses from the sale of

available-for-sale

securities during the years ended December 31, 2019, 2018, and 2017:

Gross realized gains		5,445		967		3,848
Gross realized losses		—		981		860

Net unrealized gains on equity securities recognized in earnings for the year ended December 31, 2019 were $2.3 million. Net unrealized losses on equity securities recognized in earnings for the year ended December 31, 2018 were $2.0 million.

In addition,

during the twelve months ended December 31, 2017, the Company sought to take advantage of favorable bond market conditions and sold

held-to-maturity

securities with an amortized cost of $521.0 million resulting in gross proceeds of $547.9 million including a gross realized gain of $26.9 million. Accordingly, the Company transferred the remaining $3.0 billion of

held-to-maturity

securities to

available-for-sale

with a net unrealized gain of $82.8 million classified in other comprehensive loss in the Consolidated Statements of Condition. Having the securities portfolio classified as

available-for-sale

improves the Company’s liquidity measures.

In the following table, the beginning balance represents the credit loss component for debt securities on which OTTI occurred prior to January 1, 2019. For credit-impaired debt securities, OTTI recognized in earnings after that date is presented as an addition in two components, based upon whether the current period is the first time a debt security was credit-impaired (initial credit impairment) or is not the first time a debt security was credit-impaired (subsequent credit impairment).

An OTTI loss on impaired debt securities must be fully recognized in earnings if an investor has the intent to sell the debt security, or if it is more likely than not that the investor will be required to sell the debt security before recovery of its amortized cost. However, even if an investor does not expect to sell a debt security, it must evaluate the expected cash flows to be received and determine if a credit loss has occurred. In the event that a credit loss occurs, only the amount of impairment associated with the credit loss is recognized in earnings. Amounts of impairment relating to factors other than credit losses are recorded in AOCL.

At December 31, 2019, the Company had unrealized losses on certain available for sale GSE obligations, municipal bonds, corporate bonds, asset-backed securities, capital trust notes, and equity investments with readily determinable fair values. The unrealized losses on the Company’s GSE obligations, municipal bonds, corporate bonds, asset-backed securities and capital trust notes at December 31, 2019 were primarily caused by movements in market interest rates and spread volatility, rather than credit risk. These securities are not expected to be settled at a price that is less than the amortized cost of the Company’s investment.

The Company reviews quarterly financial information related to its investments in capital trust notes, as well as other information that is released by each of the issuers of such notes, to determine their continued creditworthiness. The Company continues to monitor these investments and currently estimates that the present value of expected cash flows is not less than the amortized cost of the securities. It is possible that these securities will perform worse than is currently expected, which could lead to adverse changes in cash flows from these securities and potential OTTI losses in the future. Future events that could trigger material unrecoverable declines in the fair values of the Company’s investments, and thus result in potential OTTI losses, include, but are not limited to, government intervention; deteriorating asset quality and credit metrics; significantly higher levels of default and loan loss provisions; losses in value on the underlying collateral; net operating losses; and illiquidity in the financial markets.

The unrealized losses on the Company’s equity investments with readily determinable fair values at December 31, 2019 were caused by market volatility. Equity investments with readily determinable fair values are measured at fair value with changes in fair value recognized in net income, thus eliminating eligibility for the

available-for-sale

category. Events that could trigger a material decline in the fair value of these securities include, but are not limited to, deterioration in the equity markets; a decline in the quality of the loan portfolio of the issuer in which the Company has invested; and the recording of higher loan loss provisions and net operating losses by such issuer.

The investment securities designated as having a continuous loss position for twelve months or more at December 31, 2019 consisted of seven US Government agency securities, five capital trusts notes, three agency mortgage-related securities, three agency

CMO

three asset backed

sec

urities, two corporate bonds,

one municipal bond, and one mutual fund. At December 31, 2018 securities designated as having a continuous loss position for twelve months or more consisted of nine agency mortgage-related securities, nine US Government agency securities, seven agency

, five capital trusts notes, three municipal bonds, and one mutual fund.

At December 31, 2019, the fair value of securities having a continuous loss position for twelve months or more was 2.3% below the collective amortized cost of $642.3 million. At December 31, 2018, the fair value of such securities was 2.9% below the collective amortized cost of $782.4 million. At December

, 2019 and

2018

, the combined market value of the respective securities represented unrealized losses of $14.8 million and $22.5 million, respectively.
