Loan Loss Reserve When a repurchase demand corresponding to a mortgage loan previously held for sale and sold to a third-party investor is received from a third-party investor, the relevant data is reviewed and captured so that an estimated future loss can be calculated. The key factors that are used in the estimated loss calculation are as follows: (i) lien position, (ii) payment status, (iii) claim type, (iv) unpaid principal balance, (v) interest rate, and (vi) validity of the demand. Other data is captured and is useful for management purposes; the actual estimated loss is generally based on these key factors. The Company conducts its own review upon the receipt of a repurchase demand. In many instances, the Company is able to resolve the issues relating to the repurchase demand by the third-party investor without having to make any payments to the investor. The following is a summary of the loan loss reserve which is included in other liabilities and accrued expenses:
|  | December 31

The Company maintains reserves for estimated losses on current production volumes. For the year ended December 31, 2020, $4,938,214 in reserves were added at a rate of 8.9 basis points per loan, the equivalent of $890 per $1,000,000 in loans originated. This is an increase over the year ended December 31, 2019, when $643,284 in reserves were added at a rate of 2.5 basis points per loan originated, the equivalent of $250 per $1,000,000 in loans originated. The Company also increased its loan loss reserve for the year ended December 31, 2020 by an additional $16,506,030 to account for changes in estimates specific to settlements of loan losses. See Note 10 for additional information regarding mortgage loan loss settlements. The economic impact of COVID-19 and subsequent government action has increased the potential for losses due to early payoff penalties and potential for losses due to increased delinquency. The unique nature of these current events creates significant difficulty for forecasting potential future losses. The Company will continue to monitor data and economic conditions in order to maintain adequate loss reserves on current production. Thus, the Company believes that the final loan loss reserve as of December 31, 2020, represents its best estimate for adequate loss reserves on loans sold.
