At December 31, 2021 and 2020, the Company had 160 and 36 individual available-for-sale securities with unrealized losses totaling $4,032 and $321, respectively, with an aggregate depreciation of 1.77% and 1.01%, respectively, from the Company’s amortized cost.

Management believes that none of the unrealized losses on available for sale securities are other-than-temporary because substantially all of the unrealized losses in the Company’s investment portfolio relate to market interest rate changes on debt and mortgage-backed securities issued either directly by the government or from government sponsored enterprises. Because the Company does not intend to sell the securities and it is not likely that the Company will be required to sell the securities before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired either at December 31, 2021 or 2020.

The amortized cost and fair value of available for sale debt securities at December 31, 2021 and 2020, by contractual maturities, are presented below. Actual maturities of mortgage-backed securities may differ from contractual maturities because the mortgages underlying the securities may be called or repaid without any penalties. Because mortgage-backed securities are not due at a single maturity date, they are not included in the maturity categories in the following maturity summary:


	December 31, 2021				December 31, 2020
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Maturity:
Within 1 year	$	12,729	$	12,726	$	102	$	102
After 1 but within 5 years		67,912		67,463		2,155		2,155
