Reconciliation of Net income to Adjusted EBITDA 1 Includes non-corporate tax expense. Non-corporate tax expense is included within general and administrative expenses in our Unaudited Consolidated Statements of Operations. Prior to the IPO and Reorganization Transactions we did not have any corporate income tax expense. 2 Includes equity-based compensation to employees and directors, as well as equity-based payments to non-employees. 3 Includes the non-cash impact of the initial recognition of servicing liabilities and subsequent fair value changes in such servicing liabilities during the periods presented. 4 Non-recurring transaction expenses include costs associated with our IPO, which were not deferrable against the proceeds of the IPO. Further, certain costs related to our March 2018 term loan upsizing were expensed as incurred, rather than deferred against the balance of the term loan, and therefore are being added back to Net income given the non-recurring nature of these expenses. 39 6 months ended June 30 3 months ended June 30 ($ in thousands)2015 2016 2017 2017 2018 2017 2018 Net income$ 93,819 $ 124,464 $138,668 Interest expense --7,536 Tax expense1 187 281 309 Depreciation and amortization2,356 3,708 3,983 Equity-related expense2 1,094 2,288 4,253 Fair value change in servicing liabilities3--2,071 Non-recurring transaction expenses4 --2,612 $ 60,604 $ 59,420 174 11,378 172 1,806 1,875 2,037 1,772 2,859 -201 -1,882 $ 38,593 $ 40,816 110 5,787 100 1,740 909 1,067 1,078 1,854 -85 -759 Adjusted EBITDA$ 97,456 $ 130,741 $ 159,432 $ 64,597 $ 79,583 $ 40,790 $ 52,108 Revenue173,457 263,865 325,887 147,757 191,030 82,420 105,704 Adjusted EBITDA margin 56% 50% 49% 44% 42% 49% 49%
