On July 23, 2018, Enova International, Inc. (the “Company”) and several of its subsidiaries entered into a receivables funding (the “2018-1 Facility”) with Pacific Western Bank, as lender (the “Lender”). The 2018-1 Facility collateralizes unsecured consumer installment loans (“Receivables”) that have been and will be originated or acquired under the Company’s NetCredit brand by several of the Company’s subsidiaries and that meet specified eligibility criteria in exchange for a revolving note. Under the 2018-1 Facility, Receivables are sold to a wholly-owned special purpose subsidiary of the Company (the “Debtor”) and serviced by another subsidiary of the Company.

The Debtor has issued a revolving note with an initial maximum principal balance of $150.0 million, which is required to be secured by 1.25x of the drawn amount in eligible Receivables. The 2018-1 Facility is non-recourse to the Company and matures on July 22, 2023 (the “Final Maturity Date”).

The 2018-1 Facility is governed by a loan and security agreement, dated as of July 23, 2018, between the Lender and the Debtor. The 2018-1 Facility bears interest at a rate per annum equal to LIBOR (subject to a floor) plus an applicable margin, which rate per annum is initially 4.00%. In addition, the Debtor paid certain customary upfront closing fees to the Lender. Interest payments on the 2018-1 Facility will be made monthly. The Debtor shall be permitted to prepay the 2018-1 Facility, subject to certain fees and conditions. In the event of prepayment for the purposes of securitizations, no fees shall apply. Any remaining amounts outstanding will be payable no later than the Final Maturity Date.

All amounts due under the 2018-1 Facility are secured by all of the Debtor’s assets, which include the Receivables transferred to the Debtor, related rights under the Receivables, a bank account and certain other related collateral.

The 2018-1 Facility documents contain customary provisions for securitizations, including: representations and warranties as to the eligibility of the Receivables and other matters; indemnification for specified losses not including losses due to the inability of consumers to repay their loans; covenants regarding special purpose entity matters; and default and termination provisions which provide for the acceleration of the 2018-1 Facility in circumstances including, but not limited to, failure to make payments when due, servicer defaults, certain insolvency events, breaches of representations, warranties or covenants, failure to maintain the security interest in the receivables and defaults under other material indebtedness of the Debtor.

On July 26, 2018, the Company issued a press release to announce its consolidated financial results for the three and six months ended June 30, 2018. A copy of the Company’s press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The press release includes non-GAAP financial measures as that term is defined in Regulation G. The press release also includes the most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the United States (“GAAP”), information reconciling the non-GAAP financial measures to the GAAP financial measures, and a discussion of the reasons why the Company’s management believes that presentation of the non-GAAP financial measures provides useful information to investors regarding the Company’s financial condition and results of operations. The non-GAAP financial information presented therein should be considered in addition to, not as a substitute for, or superior to, financial measures calculated and presented in accordance with GAAP.
