EAST WEST BANCORP, INC. AND SUBSIDIARIES GAAP TO NON-GAAP RECONCILIATION ($ in thousands) (unaudited) Table 13 The Company uses certain non-GAAP financial measures to provide supplemental information regarding the Company’s performance. Non-GAAP measures used consist of FTE net interest income and total revenue. The FTE adjustment relates to tax exempt interest on certain investment securities and loans. Adjusted noninterest expense reflects the FDIC special assessment. Efficiency ratio (FTE) represents noninterest expense divided by total revenue (FTE). Adjusted efficiency ratio and adjusted efficiency ratio (FTE) reflect the impacts of the aforementioned adjustments.

Tangible book value and tangible assets represent stockholders’ equity and total assets, respectively, which have been reduced by goodwill and mortgage servicing assets. Given that the use of such measures and ratios is more prevalent in the banking industry, and are used by banking regulators and analysts, the Company has included them below for discussion.
