At December 31, 2019 and 2018, the Company had 80 and 96 individual available-for-sale securities with unrealized losses totaling $861 and $3,273, respectively, with an aggregate depreciation of 1.21% and 3.35%, 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, 2019 or 2018.

The amortized cost and fair value of available for sale debt securities at December 31, 2019 and 2018, 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, 2019				December 31, 2018
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Maturity:
Within 1 year	$	175	$	175	$	1,221	$	1,210
After 1 but within 5 years		7,027		7,001		17,253		16,780
After 5 but within 10 years		7,806		7,899		1,975		1,945
After 10 years		675		670		734		736
Total Maturities		15,683		15,745		21,183		20,671
