CHATTANOOGA, Tenn. (March 10, 2009) – At meetings with investors to be held on March 11, 2009, Unum Group (NYSE: UNM) intends to reaffirm the Company’s full-year 2009 operating earnings per diluted share guidance of $2.45 to $2.55. The Company also intends to reaffirm its guidance for year-end 2009 capital management targets with holding company liquidity expected to be greater than $750 million, combined weighted average risk-based capital for its traditional US insurance companies within a range of 330 percent to 335 percent, and a leverage ratio within a range of 20 percent to 21 percent, excluding the non-recourse debt and associated capital of Tailwind Holdings and Northwind Holdings.

Non-GAAP Measures

In calculating full year 2009 earnings per diluted share guidance, the Company has excluded amounts for realized investment gains or losses and the related tax thereon that are required to be included in the calculation of net income determined in accordance with generally accepted accounting principles in the United States (GAAP). The Company believes operating income, excluding realized investment gains and losses, which are recurring, is a better performance measure and a better indicator of the profitability and underlying trends in its business. Realized investment gains and losses are primarily dependent on market conditions and general economic events and are not necessarily related to decisions regarding the Company’s underlying business. The Company’s 2009 leverage ratio guidance excludes the above referenced items that would be included in calculating the leverage ratio using GAAP amounts. These items have been excluded and not presented because appropriate estimates for these amounts are not currently determinable.
