Item 4.01 Changes in Registrant’s Certifying Accountant.

On May 28, 2014, Pendrell Corporation, a Washington corporation (the “Company”), dismissed Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm. The Company, also on May 28, 2014, engaged Grant Thornton LLP (“Grant Thornton”) as its new independent registered public accounting firm. The Audit Committee of the Company’s Board of Directors (the “Audit Committee”) made the decision to dismiss Deloitte and engage Grant Thornton as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2014.

The reports of Deloitte on the consolidated financial statements of the Company as of and for the years ended December 31, 2013 and 2012 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

During the Company’s two most recent fiscal years and any subsequent interim period through May 28, 2014, the Company did not have any disagreement with Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to the satisfaction of Deloitte, would have caused it to make reference to the subject matter of any such disagreement in connection with its report.

During the Company’s two most recent fiscal years and any subsequent interim period through May 28, 2014, no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K have occurred.

The Company has provided Deloitte with a copy of the foregoing disclosures made in response to this Item 4.01 and has requested Deloitte to furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not Deloitte agrees with the foregoing statements made by the Company. A copy of Deloitte’s letter is filed as Exhibit 16.1 to this current report on Form 8-K.

The Company has not consulted with Grant Thornton during its two most recent fiscal years or during any subsequent interim period prior to its appointment as the Company’s independent auditor with respect to any of the matters specified in 304(a)(2) of Regulation S-K.

Item 9.01 Financial Statements and Exhibits.
