PART IV ITEM 15 Report of Independent Registered Public Accounting Firm on Financial Statement Schedules Report of Independent Registered Public Accounting Firm on Financial Statement Schedules To the Board of Directors and Shareholders of Cigna Corporation Our audits of the consolidated financial statements and of the effectiveness of internal control over financial reporting referred to in our report dated February 28, 2013 (which report and consolidated financial statements are included under Item 8 in this Annual Report on Form 10-K) also included an audit of the financial statement schedules listed in Item 15(a)(2) of this Form 10-K. In our opinion, these financial statement schedules present fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. As discussed in Note 2 to the consolidated financial statements, as of January 1, 2012, the Company retrospectively adopted a new accounting standard that amends the accounting for costs incurred by insurance companies that can be capitalized in connection with acquiring or renewing insurance contracts. /s/ PricewaterhouseCoopers LLP Philadelphia, Pennsylvania February 28, 2013 As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded Great American Supplemental Benefits Group from its assessment of internal control over financial reporting as of December 31, 2012 because it was acquired by the Company in a purchase business combination during the year ended December 31, 2012. We have also excluded Great American Supplemental Benefits Group from our audit of internal control over financial reporting. Great American Supplemental Benefits Group’s total assets acquired represent approximately 2% of consolidated total assets as of December 31, 2012; total revenues acquired represent less than 1% of consolidated total revenues for the year ended December 31, 2012.
