Investments Classified by Contractual Maturity Date
The following summarizes, by class and contractual maturity, the amortized cost and estimated fair value of available-for-sale debt securities held as of September 30, 2023 and December 31, 2022. The mortgages underlying the mortgage-backed securities are not due at a single maturity date. Additionally, these mortgages often are and generally may be pre-paid without penalty, creating a degree of uncertainty that such investments can be held until maturity. For convenience, mortgage-backed securities have been included in the summary as a separate line item.
