Our report dated March 1, 2017, on the effectiveness of internal control over financial reporting as of December 31, 2016, expresses our opinion that Banc of California, Inc. did not maintain effective internal control over financial reporting as of December 31, 2016 because of the effect of a material weakness related to inadequate tone at the top regarding the importance of internal control over financial reporting, which adversely impacted a number of processes resulting in an ineffective risk assessment process, ineffective monitoring activities, and insufficient resources or support and caused the Company to experience an increase in the number of control deficiencies across multiple processes that has been identified as described in Management’s Report on Internal Control over Financial Reporting.
