Oportun Financial Corp

Our Management's Discussion and Analysis of Financial Condition and Results of Operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and the related disclosures. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2, Summary of Significant Accounting Policies, in our Notes to the Consolidated Financial Statements included elsewhere in this report, we believe the following critical accounting policies affect the more significant estimates, assumptions and judgments we use to prepare our consolidated financial statements.

Fair Value of Loans Held for Investment

We elected the fair value option for our loans receivable held for investment. We primarily use a discounted cash flow model to estimate fair value based on the present value of estimated future cash flows. This model uses inputs that are not observable but reflect our best estimates of the assumptions a market participant would use to calculate fair value. The following describes the primary inputs that require significant judgment:

•Remaining Cumulative Charge-offs- Remaining cumulative charge-offs are estimates of the principal payments that will not be repaid over the life of a loan held for investment. Remaining cumulative loss expectations are adjusted to reflect the expected principal recoveries on charged-off loans. Remaining cumulative loss expectations are primarily based on the historical performance of our loans but also incorporate adjustments based on our expectations of future credit performance and are quantified by the remaining cumulative charge-off rate.

•Remaining Cumulative Prepayments- Remaining cumulative prepayments are estimates of the principal payments that will be repaid earlier than contractually required over the life of a loan held for investment. Remaining cumulative prepayment rates are primarily based on the historical performance of our loans but also incorporate adjustments based on our expectations of future borrower behavior and refinancings through our Good Customer Program. For credit card receivables, we estimate the principal payment rate which is the amount of principal we expect to get repaid each month.

•Average Life- Average life is the time weighted average of the estimated principal payments divided by the principal balance at the measurement date. The timing of estimated principal payments is impacted by scheduled amortization of loans, charge-offs, and prepayments.

•Discount Rates- The discount rates applied to the expected cash flows of loans held for investment reflect our estimates of the rates of return that investors would require when investing in financial instruments with similar risk and return characteristics. Discount rates are based on our estimate of the rate of return likely to be received on new loans. Discount rates for aged loans are adjusted to reflect the market relationship between interest rates and remaining time to maturity.

We developed an internal model to estimate the fair value of loans receivable held for investment. To generate future expected cash flows, the model combines receivable characteristics with assumptions about borrower behavior based on our historical loan performance. These cash flows are then discounted using a required rate of return that management estimates would be used by a market participant.

We test the fair value modelby comparing modeled cash flows to historical loan performance to ensure that the model is complete, accurate and reasonable for our use. In addition, we engage a third party to create an independent fair value estimate for the Loans Receivable at Fair Value, which provides a set of fair value marks using the Company’s historical loan performance data and whole loan sale prices to develop independent forecasts of borrower behavior.

As discussed above, our fair value model uses inputs that are not observable but reflect our best estimates of the assumptions a market participant would use to calculate fair value. For a summary of how these inputs have changed over the last eight quarters since January 1, 2021, refer to Fair Value Estimate Methodology for Loans Receivable at Fair Value in Item 7.
