Line Of Credit Facility [Abstract]
Line Of Credit Facility	7. Line of Credit Facility On April 25, 2011, the Company amended its line of credit facility (the "Line") with Wells Fargo Bank, National Association. This amendment extended the term of the Line for three years, increased the accordion feature from $100 million to $175 million, reduced the interest rate margin for certain cash advances and modified certain financial covenants and terms. The Line contains a sub-limit for borrowings by the Company's European subsidiaries that are guaranteed by the Company. Cash advances bear interest at LIBOR plus 0.50% to 1.50% based on the Company's achievement of prescribed adjusted debt ratios. The Line subjects the Company to various restrictive covenants, including maintenance of certain financial ratios such as adjusted debt. The covenants also include limitations on the Company's capital expenditures, ability to repurchase shares and the payment of cash dividends. On October 31, 2011, the Company further amended the Line to revise certain financial covenants which included removing the limitation on share repurchases, as well as to join certain subsidiaries of the Company as additional borrowers and guarantors and release certain others. As of and for the year ended January 31, 2012, there were no borrowings under the Line. Outstanding letters of credit and stand-by letters of credit under the Line totaled approximately $59,685 as of January 31, 2012. The available credit, including the accordion feature, under the Line was $115,315 as of January 31, 2012.
