deductions. The loans have maturity dates ranging from 2020 to 2028 with interest rates ranging from 4.25% to 6.50%.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Accounting — The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").
Use of Estimates — The preparation of financial statements in conformity with GAAP requires Plan management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from those estimates.
Risk and Uncertainties — The Plan utilizes various investment instruments, including mutual funds, common stock, a common collective trust, self-directed brokerage accounts, and interest-bearing cash funds. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements.
Included in investments at December 31, 2019 and 2018 are shares of the Company’s common stock with a fair value of $25,093,786 and $38,884,153, respectively, held by the plan within participant accounts. This investment represents 19.8% and 31.8% of total investments at December 31, 2019 and 2018, respectively. Additionally, at December 31, 2019 and 2018 there were shares of the Company’s common stock with a fair value of $1,047,587 and $1,046,438, respectively, held by the Plan within self-directed brokerage accounts. This investment represents 0.8% and 0.9% of total investments at December 31, 2019 and 2018, respectively. A significant decline in the market value of the Company’s stock would significantly affect the net assets available for benefits.
Payment of Benefits — Benefit payments to participants are recorded upon distribution. There were no amounts allocated to accounts of former participants who elected to withdraw from the Plan but had not been paid at December 31, 2019 and 2018.
Excess Contributions Payable — The Plan is required to return contributions received during the Plan year in excess of IRC limits. As of December 31, 2019 and 2018, total excess contributions payable was approximately $152,489 and $146,358.
Investment Valuation and Income Recognition — The Plan’s investments are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
