As of December 31, 2020, the Company held 649 investment securities of which 13 were in an unrealized loss position for less than twelve months and 83 securities were in an unrealized loss position for twelve months or more. Management periodically evaluates each investment security for other-than-temporary impairment relying primarily on industry analyst reports and observations of market conditions and interest rate fluctuations. Management believes it will be able to collect all amounts due according to the contractual terms of the underlying investment securities.

Securities of Government Agency and Government Sponsored Entities – At December 31, 2020 and December 31, 2019, no securities of government agency and government sponsored entities were in a loss position.

U.S. Treasury Notes – At December 31, 2020 and December 31, 2019, no U.S. Treasury Note security investments were in a loss position.

U.S. Government SBA – At December 31, 2020, 8 U.S. Government SBA security investments were in a loss position for less than 12 months and 65 were in a loss position for 12 months or more. The unrealized losses on the Company's investment in U.S. Government SBA were $93,000 at December 31, 2020 and $113,000 at December 31, 2019. The unrealized losses were caused by interest rate fluctuations. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2020 and December 31, 2019.

Mortgage Backed Securities - At December 31, 2020, 3 mortgage backed security investments were in a loss position for less than 12 months and 18 were in a loss position for 12 months or more. The unrealized losses on the Company's investment in mortgage-backed securities were $48,000 at December 31, 2020 and $99,000 at December 31, 2019. The unrealized losses were caused by interest rate fluctuations. The contractual cash flows of these investments are guaranteed by an agency or government sponsored entity of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2020 or 2019.

Corporate Securities - At December 30, 2020, 2 corporate securities were in an unrealized loss position for less than 12 months and none were in a loss position for 12 months or more. The unrealized losses on the Company’s investment in corporate securities were $18,000. Changes in the prices of corporate securities are primarily influenced by: (1) changes in market interest rates; (2) changes in perceived credit risk in the general economy or in particular industries; (3) changes in the perceived credit risk of a particular company; and (4) day to day trading supply, demand and liquidity. The Company monitors the status of each of our corporate securities and at the current time does not believe any of them to be exhibiting financial problems that could result in a loss in any individual security. Because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company does not consider these investments to be other-than-temporarily impaired at December 30, 2020.

Obligations of States and Political Subdivisions - At December 31, 2020, no obligations of states and political subdivisions were in a loss position for less than 12 months. None were in a loss position for 12 months or more. As of December 31, 2020, one-hundred percent of the Company’s bank-qualified municipal bond portfolio is rated at either the issue or the issuer level, and all of these ratings are “investment grade.” The Company monitors the status of all municipal investments in the portfolio, and at the current time does not believe any of them to be exhibiting financial problems that could result in a loss in any individual security.

The unrealized losses on the Company’s investment in obligation of states and political subdivisions were $0 at December 31, 2020 and $12,000 at December 31, 2019. Management believes that any unrealized losses on the Company's investments in obligations of states and political subdivisions were caused by interest rate fluctuations. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the Company does not intend to sell the securities and it is more likely than not that the Company would not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2020 and December 31, 2019.

Proceeds from sales and calls of these securities were as follows:
