(1)The gross unrealized losses recognized in OCI on securities held to maturity resulted from a transfer of securities available for sale to held to maturity in the second quarter of 2013.

Debt securities with carrying values of $9.8 billion and $10.3 billion at June 30, 2021, and December 31, 2020, respectively, were pledged to secure public funds, trust deposits and certain borrowing arrangements. Included within total pledged securities is approximately $24 million of encumbered U.S. Treasury securities at both June 30, 2021, and December 31, 2020.

The amortized cost and estimated fair value of debt securities held to maturity and debt securities available for sale at June 30, 2021, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The following tables present gross unrealized losses and the related estimated fair value of debt securities available for sale at June 30, 2021, and December 31, 2020.

The number of individual debt positions in an unrealized loss position in the tables above increased from 129 at December 31, 2020, to 321 at June 30, 2021. The increase in the number of securities and the total amount of unrealized losses from year-end 2020 was primarily due to changes in market interest rates. In instances where an unrealized loss existed, there was no indication of an adverse change in credit on the underlying positions in the tables above. As it relates to these positions, management believes no individual unrealized loss, other than those discussed below, represented credit impairment as of those dates. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell, the positions before the recovery of their amortized cost basis, which may be at maturity.

Gross realized gains and gross realized losses on sales of debt securities available for sale were immaterial for the three and six months ended June 30, 2021 and 2020. The cost of securities sold is based on the specific identification method. As part of the Company's normal process for evaluating impairment, management did not identify any positions where impairment was believed to exist in either of the three and six months ended June 30, 2021 or 2020.
