Interest expense, net $ 164.7 $ 169.6 $ (4.9)
Interest expense, net for the year ended December 31, 2012 decreased, compared to prior year period, primarily due to
lower average outstanding debt balances in 2012 and the financing commitment fees incurred in 2011 related to the acquisition
of Celera.

The decrease in the effective income tax rate for the year ended December 31, 2012, compared to the prior year
period, is due primarily to the Medi-Cal charge in 2011, a portion for which a tax benefit was not recorded.

million and $18.2 million, respectively. Discrete income tax benefits for 2011 were primarily associated with certain state tax
