Item 2.02 Results of Operations and Financial Condition.

As announced in November 2011, MetLife, Inc. (“MetLife”) reorganized its business from a U.S. and International business structure into three broad geographic regions to better reflect its global reach. As a result, in the first quarter of 2012, MetLife reorganized into six segments, reflecting these broad geographic regions: Retail Products; Group, Voluntary and Worksite Benefits; Corporate Benefit Funding; and Latin America (collectively, “The Americas”); Asia; and Europe, the Middle East and Africa (“EMEA”). In addition, MetLife reports certain of its results of operations in Corporate & Other, which includes MetLife Bank and other business activities.

In addition, in the first quarter of 2012, MetLife adopted and retrospectively applied the new guidance (ASU 2010-26) regarding accounting for deferred acquisition costs (“DAC”). This guidance specifies that only costs related directly to successful acquisition of new or renewal contracts can be capitalized as DAC; all other acquisition-related costs must be expensed as incurred. Under the new guidance, advertising costs may only be included in DAC if the capitalization criteria in the direct-response advertising guidance in Subtopic 340-20, Other Assets and Deferred Costs—Capitalized Advertising Costs, are met. As a result, certain direct marketing, sales manager compensation and administrative costs currently capitalized by the Company will no longer be deferred.

To reflect the reorganized segments, MetLife has adopted a new presentation format for its Quarterly Financial Supplement (“QFS”), which will be used beginning with the QFS for the first quarter of 2012. To aid investors’ understanding of the impact of the segment reorganization and the new guidance regarding accounting for DAC, MetLife has revised the information presented in its QFS for the quarters ended March 31, 2011, June 30, 2011, September 30, 2011 and December 31, 2011 and attached such revised historical financial results (the “Historical Results Financial Supplement”) to this Form 8-K as Exhibit 99.1.

The Historical Results Financial Supplement attached hereto as Exhibit 99.1 is furnished and not filed pursuant to instruction B.2 of Form 8-K.
