in light of the anticipated material non-cash charges to be recorded in connection with our financial guarantee arrangements as required subsequent to the adoption and implementation of asu 2016-13 -as discussed in note 1 to the notes to consolidated financial statements in item 8 within " accounting standards issued but not yet adopted – measurement of credit losses on financial instruments " management is evaluating both the disclosure of additional non-gaap financial measures and the modification of its historical computation of adjusted ebitda commencing in 2020 to enhance the disclosure of indicators of our business performance over the long term and to provide additional useful information to users of our financial statements .
further we utilize adjusted pro forma net income which we define as consolidated net income adjusted for -i transaction and non-recurring expenses ; -ii for 2019 losses associated with the financial guarantee arrangement for a bank partner that did not renew its loan origination agreement ; and -iii incremental pro forma tax expense assuming all of our noncontrolling interests were subject to income taxation .
adjusted pro forma net income is a useful measure because it makes our results more directly comparable to public companies that have the vast majority of their earnings subject to corporate income taxation .
adjusted pro forma net income has limitations as an analytical tool and should not be considered in isolation from or as a substitute for the analysis of other gaap financial measures such as net income .
some of the limitations of adjusted pro forma net income include : .
• it makes assumptions about tax expense which may differ from actual results ; and • it is not a universally consistent calculation which limits its usefulness as a comparative measure .
management compensates for the inherent limitations associated with using the measure of adjusted pro forma net income through disclosure of such limitations presentation of our financial statements in accordance with gaap and reconciliation of adjusted pro forma net income to the most directly comparable gaap measure net income as presented below .
-1 includes losses recorded in the fourth quarter of 2019 associated with the financial guarantee arrangement for a bank partner that did not renew its loan origination agreement when it expired in november 2019 .
