ITEM 4.01           CHANGES IN REGISTRANT’S CERTIFYING ACCOUNTANT.

On June 30, 2015, PricewaterhouseCoopers Ltd. (“PwC”) resigned as the independent registered public accounting firm of Blue Capital Reinsurance Holdings Ltd. (the “Registrant”).

This resignation was due to an independence matter which resulted from the proposed acquisition of Montpelier Re Holdings Ltd. (“Montpelier’) by Endurance Specialty Holdings Ltd. (“Endurance”). The independence conflict results from a retired partner of PricewaterhouseCoopers LLP being on Endurance’s Board of Directors and serving as the Chair of Endurance’s Audit Committee.  Montpelier currently owns 33.3% of the Registrant’s outstanding common shares and fully consolidates the assets, liabilities and operations of the Registrant and its subsidiaries within its consolidated financial statements.

The reports of PwC on the financial statements for the fiscal years ended December 31, 2014 and 2013 contain no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal years ended December 31, 2014 and 2013, and the subsequent interim period through June 30, 2015, there were no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to their satisfaction would have caused them to make reference thereto in their report on the financial statements for such years, nor were there any reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The Registrant has requested that PwC furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of such letter, dated July 2, 2015, is filed as Exhibit 16 to this Form 8-K.

The Registrant expects to announce a new independent registered public accounting firm prior to the completion of the acquisition of Montpelier by Endurance. The Registrant will file a Current Report on Form 8-K with the Securities and Exchange Commission promptly following the engagement of a new independent registered public accounting firm.

ITEM 8.01           OTHER EVENTS.

On June 30, 2015, PwC resigned as the independent registered public accounting firm of the Registrant due to an independence matter which resulted from the proposed acquisition of Montpelier by Endurance. PwC has furnished a letter to the Securities and Exchange Commission relating to its resignation, dated July 2, 2015, which is filed as Exhibit 16 to this Form 8-K.
