Reconciliation of Non-GAAP Measures TCE Calculations and Reconciliation to Total Shareholders' Equity (Unaudited) The Company utilizes the term Tangible Common Equity (TCE), a non-GAAP financial measure. CU Bancorp’s management believes TCE is useful because it is a measure utilized by both regulators and market analysts in evaluating a consolidated bank holding company’s financial condition and capital strength. TCE represents common shareholders’ equity less goodwill and certain intangible assets. A reconciliation of CU Bancorp’s total shareholders’ equity to TCE is provided in the table below for the periods indicated: June 30, 2016 March 31, 2016 December 31, 2015 September 30, 2015 June 30, 2015 March 31, 2015 Tangible Common Equity Calculation Total shareholders' equity $ 326,459 $ 315,988 $ 306,807 $ 298,348 $ 290,606 $ 285,067 Less: Serial preferred stock 17,086 17,148 16,995 16,739 16,487 16,235 Less: Goodwill 64,603 64,603 64,603 63,950 63,950 63,950 Less: Core deposit and leasehold right intangibles, net 6,932 7,301 7,671 8,138 8,608 9,078 Tangible Common Equity $ 237,838 $ 226,936 $ 217,538 $ 209,521 $ 201,561 $ 195,804
