Debt Disclosure [Abstract]
Debt Disclosure Text Block	11. On March 27, 2012, the Company's $250 million credit agreement was terminated in connection with the execution of an amendment to a new unsecured revolving credit agreement. The new credit agreement is with a syndicate of lenders and expires in March 2017. It provides up to $450 million of committed credit, available for general corporate purposes, working capital needs, share repurchases and acquisitions. The Company may borrow up to $50 million under the swingline portion of the facility for daily working capital needs. Loans denominated in U.S. Dollars bear interest, at the Company's option, at either a base rate or a LIBOR-based rate. Loans denominated in currencies other than U.S. Dollars bear interest at a LIBOR-based rate. The base rate is an annual rate equal to a margin ranging from 0% to 1%, depending on the Company's cash flow leverage ratio (debt to earnings before interest, taxes, depreciation, amortization and extraordinary, non-operating or non-cash charges and expenses), plus the highest of (i) the bank's prime rate, (ii) the federal funds rate plus 0.5% or (iii) one-month LIBOR plus 1.5%. In general, LIBOR-based loans bear interest at LIBOR plus 1% to 2%, depending on the Company's cash flow leverage ratio. The Company is also required to pay a fee on the undrawn amount of the loan commitment at an annual rate ranging from 0.15 percent to 0.40 percent, depending on the Company's cash flow leverage ratio. In 2011, the Company entered into a note agreement and sold $300 million of unsecured notes with maturities ranging from 2018 to 2026. The notes have a carrying amount of $300 million and an estimated fair value of $330 million as of September 28, 2012. The Company uses significant other observable inputs to estimate fair value based on the present value of future cash flows and rates that would be available for issuance of debt with similar terms and remaining maturities. The Company's debt agreements require the Company to maintain certain financial ratios as to cash flow leverage and interest coverage. The Company is in compliance with all financial covenants of its debt agreements.
