Notes:

(1) Definition of the three-level fair value hierarchy:

•Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities

•Level 2 - Other inputs that are directly or indirectly observable in the markets

•Level 3 - Inputs that are generally unobservable

(2) Short-term investment securities will mature within 12 months or less, from the applicable reporting date.

(3) Long-term investment securities will mature between 12 and 18 months, from the applicable reporting date.

(4) The premium paid to purchase held-to-maturity investment securities was $196,385 and $80,855 for the three months ended March 31, 2020 and 2019, respectively. The premium paid to purchase held-to-maturity investment securities was $233,550 for the year ended December 31, 2019.

The Company considers the declines in market value of its investment portfolio to be temporary in nature. The Company’s investment policy requires investment securities to be investment grade and held to maturity with the primary objective to maintain a high degree of liquidity while maximizing yield. When evaluating an investment for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, changes in market interest rates, and whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s cost basis. As of March 31, 2020, the Company does not consider any of its investments to be other-than-temporarily impaired.
