Investment securities pledged to secure public deposits, repurchase agreements, trusts, certain derivative agreements, and other funds had a fair value of $3.4 billion and $3.3 billion at June 30, 2019 and December 31, 2018, respectively.

The following table presents the amortized cost, fair value, and weighted average yield of the Company's investment securities at June 30, 2019, by remaining contractual maturity, with the exception of MBS, which are based on estimated average life. Receipt of cash flows may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without penalties.

Investment Securities in an Unrealized Loss Position

The Company held certain investment securities where amortized cost exceeded fair value, resulting in unrealized loss positions. Market changes in interest rates and credit spreads may result in temporary unrealized losses as the market prices of securities fluctuate. At June 30, 2019, the Company did not intend to sell these securities nor was it more-likely-than-not that

the Company would be required to sell these securities before their anticipated recovery or maturity. The Company reviewed its portfolio for OTTI in accordance with the accounting policies described in Note 1, "Significant Accounting Policies," to the Company's 2018 Annual Report on Form 10-K.

Investment securities in an unrealized loss position at period end are presented in the following tables:

¹Unrealized losses less than $0.5 million are presented as zero within the table.

² OTTI securities AFS are impaired securities for which OTTI credit losses have been previously recognized in earnings.

The Company does not consider the unrealized losses on temporarily impaired securities AFS to be credit-related. These unrealized losses were due primarily to market interest rates

being higher than the securities' stated coupon rates, and therefore, they were recorded in AOCI, net of tax.

Realized Gains and Losses and Other-Than-Temporarily Impaired Securities

Net securities gains or losses are comprised of gross realized gains, gross realized losses, and OTTI credit losses recognized in earnings. During the three and six months ended June 30, 2019, the Company recognized $42 million in net securities losses due to the Company's repositioning of a portion of the securities AFS portfolio in the second quarter of 2019. This repositioning was not due to any requirement to sell the securities before their anticipated recovery or maturity.

Investment securities in an unrealized loss position are evaluated quarterly for other-than-temporary credit impairment, which is determined using cash flow analyses that take into account security specific collateral and transaction structure. Future expected credit losses are determined using various assumptions, the most significant of which include default rates, prepayment rates, and loss severities. If, based on this analysis, a security is in an unrealized loss position and the Company does not expect

to recover the entire amortized cost basis of the security, the expected cash flows are then discounted at the security’s initial effective interest rate to arrive at a present value amount. Credit losses on the OTTI security are recognized in earnings and reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of the security. Subsequent credit losses may be recorded on OTTI securities without a corresponding further decline in fair value when there has been a decline in expected cash flows. See Note 1, "Significant Accounting Policies," to the Company's 2018 Annual Report on Form 10-K for additional information regarding the Company's accounting policy on securities AFS and related impairments.

The Company seeks to reduce its exposure on any existing OTTI securities primarily through paydowns. In certain instances, the amount of credit losses recognized in earnings on a debt security exceeds the total unrealized losses on the security, which may result in unrealized gains relating to factors other than credit recorded in AOCI, net of tax.

During the three and six months ended June 30, 2019 and 2018, there were no credit impairment losses recognized on securities AFS held at the end of the period. The accumulated balance of OTTI credit losses recognized in earnings on securities AFS held at period end was zero at both June 30, 2019 and 2018.
