Item 4.01: Changes in Registrants Certifying Accountant.
(a) Dismissal of independent registered public accounting firm.
On April 1, 2016, Sycamore Networks, Inc. (the Company) dismissed PricewaterhouseCoopers LLP (PwC) as the
Companys independent registered public accounting firm, effective as of that same date. The dismissal of PwC was approved, after careful deliberation, by the Board of Directors of the Company (the Board) following a process to
review which audit firm would serve as the Companys independent registered public accounting firm.
PwCs reports on the
Companys consolidated financial statements as of and for the fiscal years ended July 31, 2014 and 2015 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or
accounting principle, except that the reports indicated that the Company changed its basis of accounting for periods subsequent to March 23, 2013 from the going concern basis to a liquidation basis.
During the fiscal years ended July 31, 2014 and 2015, and the subsequent interim period through April 1, 2016, there were
(i) no disagreements, within the meaning of Item 304(a)(1)(iv) of Regulation S-K, between the Company and PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to PwCs satisfaction, would have caused PwC to make reference thereto in their reports on the consolidated financial statements for such fiscal years, and (ii) no reportable events (as defined in
Item 304(a)(1)(v) of Regulation S-K).
The Company provided PwC with a copy of this Current Report on Form 8-K prior to its filing
with the United States Securities and Exchange Commission (SEC) and requested that PwC furnish the Company with a letter addressed to the SEC stating whether PwC agrees with the above statements in this Item 4.01(a). A copy of
PwCs letter, dated April 7, 2016, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Appointment of new independent
registered public accounting firm.
On April 1, 2016, the Board approved the appointment of Moody, Famiglietti & Andronico,
LLP (MFA) as the Companys independent registered public accounting firm commencing for its quarter ending April 30, 2016 and its fiscal year ending July 31, 2016.
In connection with the Companys appointment of MFA as the Companys independent registered accounting firm, the Company has not
consulted MFA on any matter relating to either (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Companys financial statements,
or (ii) any matter that was the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation
S-K).
