Amortized cost and estimated fair value of investments in securities by contractual maturity

The amortized cost and estimated fair value of investments in debt securities at December 31, 2019, by contractual maturity, are shown in the following table. 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. Because mortgage-backed securities have both known principal repayment terms as well as unknown principal repayments due to potential borrower pre-payments, it is difficult to accurately predict the final maturity of these investments. Mortgage-backed securities are shown separately (dollars in thousands):

	Available for Sale
	Amortized Cost		Fair Value
Due in one year or less	$	41,234	$	41,207
Due after one year through five years	51,039		51,814
Due after five years through ten years	56,537		57,763
