As of January 31, 2013, undistributed earnings of the Canadian subsidiary were considered to have been reinvested indefinitely and, accordingly, the Company has not provided United States income taxes on such earnings.

Uncertain Tax Positions

A summary of the activity related to the gross unrecognized tax benefits (excluding interest and penalties) is as follows:



	For the years ended January 31,
	2013			2012			2011
Gross unrecognized tax benefits at beginning of year	$	3,567		$	3,112		$	2,656
Increases in tax positions related to the current year	993			699			601
Decreases as a result of lapses in applicable statutes of limitation	(347		)	(244		)	(145		)
Gross unrecognized tax benefits at end of year	$	4,213		$	3,567		$	3,112

During the fiscal year ended January 31, 2013, the only change to uncertain tax positions related to prior years resulted from the lapse of applicable statutes of limitation. The total unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate were $2,738, $2,318 and $2,023 as of January 31, 2013, January 31, 2012 and January 31, 2011, respectively.

The Company does not expect any significant change in the amount of unrecognized tax benefits in the next fiscal year.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. At January 31, 2013, January 31, 2012 and January 31, 2011, accrued interest and penalties were $1,605, $1,379 and $1,112, respectively.

The Company files tax returns, including returns for its subsidiaries, with various federal, state and local jurisdictions. Uncertain tax positions are related to tax years that remain subject to examination. As of January 31, 2013, federal tax returns filed in the U.S., Canada and Switzerland for fiscal years ended January 31, 2008 through January 31, 2012 remain subject to examination by federal tax authorities. In state and local jurisdictions, tax returns for fiscal years ended January 31, 2005 through January 31, 2012 remain subject to examination by state and local tax authorities.
