At March 31, 2020, the Company had 11 individual available-for-sale securities in an unrealized loss position with unrealized losses totaling $47, with an aggregate depreciation of 1.91%, 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. 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, therefore, the Company did not consider those investments to be other-than-temporarily impaired at March 31, 2020.

The amortized cost and fair value of available for sale debt securities at March 31, 2020 and December 31, 2019, 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:


	March 31, 2020				December 31, 2019
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Maturity:
Within 1 year	$	175	$	175	$	175	$	175
After 1 but within 5 years		—		—		7,027		7,001
After 5 but within 10 years		7,804		8,016		7,806		7,899
After 10 years		675		650		675		670
Total Maturities		8,654		8,841		15,683		15,745
