Prior Period Reclassification Adjustment [Abstract]

Reclassification of prior periods

The Company identified certain amounts of its amortization of acquired intangible assets that were incorrectly included within cost of sales. The Company has corrected this presentation in the current period, and has conformed previous periods to the current presentation. The effect on cost of sales, gross profit and gross margins is immaterial in all periods. The amounts adjusted in each prior period are as follows:



	Three Months Ended June 30, 2012
	As Reported			As Adjusted
Cost of sales	$	149,055		$	147,337
Gross profit	203,079			204,797
Gross margin	57.7		%	58.2		%

	Three Months Ended September 30, 2011
	As Reported			As Adjusted
Cost of sales	$	145,608		$	143,899
Gross profit	194,994			196,703
Gross margin	57.2		%	57.8		%

	Six Months Ended September 30, 2011
	As Reported			As Adjusted
Cost of sales	$	300,367		$	296,949
Gross profit	414,742			418,160
Gross margin	58.0		%	58.5		%

Additionally, in the three months ended September 30, 2012, the Company determined it would separately present amortization of acquired intangible assets within operating expenses, rather than including that amortization within selling, general and administrative expenses. The Company believes this presentation better aligns with management's internal reporting, and better reflects the ongoing costs of the Company's operations.

This reclassification does not affect the Company's operating income, income from continuing operations before taxes, income tax provision, net income from continuing operations or net income for any of the years presented.
