Item 4.01   Changes in Registrant's Certifying Accountant.
(b) New Independent Registered Public Accounting Firm
On October 2, 2013, the Audit Committee of the Board of Directors (the "Audit Committee") of MRV Communications, Inc. (the "Company") engaged Grant Thornton LLP ("Grant Thornton") as the Company's independent registered public accounting firm.
During the years ended December 31, 2012 and 2011, and the subsequent interim period through October 2, 2013, neither the Company, nor anyone on its behalf, consulted with Grant Thornton with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's consolidated financial statements, and no written report or oral advice was provided by Grant Thornton to the Company that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial reporting issue or (ii) any matter that was the subject of either a disagreement as defined in Item 304(a)(1)(iv) of Regulation S-K or a reportable event as described in Item 304(a)(1)(v) of Regulation S-K.
The engagement of Grant Thornton was the culmination of a competitive process to determine the Company's independent registered public accounting firm for the fiscal year ending December 31, 2013 commenced on August 30, 2013 by the Audit Committee.
