APPENDIX
Appendix: GAAP to Non-GAAP Reconciliation EAST WEST BANCORP, INC. AND SUBSIDIARIES GAAP TO NON-GAAP RECONCILIATION ($ in thousands, except per share data) (unaudited) During the second quarter of 2019, the Company reversed $30.1 million of certain previously claimed tax credits related to the DC Solar tax credit investments (“DC Solar”). The table below shows the computation of the Company’s effective tax rate excluding the impact of the DC Solar tax credits reversal. Management believes that excluding the impact of the DC Solar tax credits reversal from the effective tax rate computation allows comparability to prior periods. Three Months Ended September 30, 2019 June 30, 2019 September 30, 2018 Income tax expense (a) $ 34,951 $ 72,797 $ 33,563 Less: Reversal of certain previously claimed tax credits related to DC Solar (b) — (30,104) — Adjusted income tax expense (c) $ 34,951 $ 42,693 $ 33,563 Income before income taxes (d) 206,367 223,177 204,865 Effective tax rate (a)/(d) 16.9% 32.6% 16.4% Less: Reversal of certain previously claimed tax credits related to DC Solar (b)/(d) —% (13.5 )% — % Adjusted effective tax rate (c)/(d) 16.9% 19.1% 16.4 % Nine Months Ended September 30, 2019 September 30, 2018 Income tax expense (e) $ 138,815 $ 82,958 Less: Reversal of certain previously claimed tax credits related to DC Solar (f) (30,104) — Adjusted income tax expense (g) $ 108,711 $ 82,958 Income before income taxes (h) 624,635 613,641 Effective tax rate (e)/(h) 22.2% 13.5% Less: Reversal of certain previously claimed tax credits related to DC Solar (f)/(h) (4.8 )% —% Adjusted effective tax rate (g)/(h) 17.4% 13.5% 15
Appendix: GAAP to Non-GAAP Reconciliation EAST WEST BANCORP, INC. AND SUBSIDIARIES GAAP TO NON-GAAP RECONCILIATION ($ in thousands, except per share data) (unaudited) During the first quarter of 2019, the Company recorded a $7.0 million pre-tax impairment charge related to DC Solar. During the second quarter of 2019, the Company reversed $30.1 million of certain previously claimed tax credits related to DC Solar. During the first quarter of 2018, the Company sold its Desert Community Bank (“DCB”) branches and recognized a pre-tax gain on sale of $31.5 million. Management believes that presenting the computations of the adjusted net income, adjusted diluted earnings per common share, adjusted return on average assets and adjusted return on average equity that exclude the after-tax impact of the impairment charge related to DC Solar, the reversal of certain previously claimed tax credits related to DC Solar and the after-tax impact of the gain on the sale of the DCB branches (where applicable) provides clarity to financial statement users regarding the ongoing performance of the Company and allows comparability to prior periods.
