Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrants under any of the following provisions (see General Instruction A.2.):

On November 16, 2016, Banc of California, Inc. (the “Company”) issued a press release announcing that it has delayed the filing of its Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2016 (the “Quarterly Report”) beyond the November 14, 2016 extended filing due date. As previously disclosed by the Company in its Form 12b-25 filed with the Securities and Exchange Commission (the “SEC”) on November 10, 2016, the Company is delaying the filing of the Quarterly Report at this time to allow for completion of a review into certain purported improper relationships and related party transactions and related matters. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

As a result of the filing delay, the Company received a letter from the New York Stock Exchange (the “NYSE”) notifying the Company that it was not currently in compliance with the NYSE’s continued listing requirements under the timely filing criteria set forth in Section 802.01E of the NYSE Listed Company Manual. Such notices are routinely issued by the NYSE in situations when there are late filings with the SEC. Under the NYSE Listed Company Manual, the Company will have six months, from November 14, 2016, to file the Quarterly Report with the SEC. The Company can regain compliance with the NYSE listing standards at any time during this six-month period once it files the Quarterly Report with the SEC. If the Company fails to file the Quarterly Report within such six-month period, the NYSE may grant, in its discretion, a further extension of up to an additional six months depending on specific circumstances as outlined in the rule.

On November 15, 2016, the Board of Directors (the “Board”) of the Company approved Amendment No. 2 to the Company’s Fourth Amended and Restated Bylaws (the “Bylaw Amendment”), effective immediately. The Bylaw Amendment extends the period of time by 30 days that stockholders may submit proposals to be presented in connection with the 2017 annual meeting of stockholders of the Company, including any nomination or proposal relating to the nomination of a director to be elected to the Board.

A copy of the Bylaw Amendment is attached to this Current Report on Form 8-K as Exhibit 3.1 and is incorporated herein by reference. The foregoing description of the Bylaw Amendment does not purport to be complete and is qualified in its entirety by reference to the Bylaw Amendment.

On November 15, 2016, the Board also declared a quarterly dividend per depository share on its Series C, D and E Preferred Stock in the amounts of $0.50, $0.460938 and $0.4375, respectively. The dividends will be payable on December 15, 2016 to record holders as of December 1, 2016 of depositary shares relating to the underlying Series C, Series D and Series E Preferred Stock of the Company.

A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.
