Rating Agency Snapshot S&P (Analyst: Andy Liu) BB / Credit Watch Positive September 3 & April 17, 2009 Summaries: "lease-adjusted EBITDA coverage of interest and lease-adjusted total debt to EBITDA were 9.2x and 2.2x respectively. Although these credit measures are better than those of typical 'BB' rated companies, Expedia's financial risks are higher than those of its similarly rated peers." "The CreditWatch placement reflects Expedia's good credit metrics and a shift toward a more conservative financial policy. Despite the global recession and its impact on travel demand, online travel agencies such as Expedia....have done relatively well." Moody's (Analyst: Stephen Sohn) Ba2 / Stable / SGL-1 Nov 26, 2008 Credit Opinion: "The company's financial leverage, as measured by debt to EBITDA, of 1.6x adjusted for leases, is similar to business services peers rated in the Aa category." "The stable outlook reflects the company's strong operating performance amidst the current economic slowdown in the U.S. While Moody's expects air and hotel bookings to remain under pressure into 2009 as a result of increased airfares (driven by airline capacity reductions) and declining hotel rates, we believe Expedia will still generate free cash flow at levels which would comfortably position the company at the Ba2 rating level. Furthermore, given the current credit climate, we believe that event risk arising from significant acquisition activity and additional shareholder friendly actions will be limited in the near to intermediate term. Accordingly, we expect leverage (debt to EBITDA on a Moody's adjusted basis) to remain well below the 2.5x threshold that could trigger downward rating pressure." Solid execution & adequate liquidity in a challenging environment
