Subscriber rev of $266M was slightly better thanUBSe of $261M. Total rev of $308M were better than UBSe of $299M. Reported EPS loss of $(0.78) was worse than UBSe of $(0.56) due to much higher revenue share and royalties.

Settlement with RIAA; lower EBITDA As a result of merger and settlement related charges, EBITDA loss of $(117)M was worse than UBSe of $(72)M. The biggest contributor was $54M more in rev share and royalties, which we believe was associated with the RIAA settlement and trueups for the quarter.
