Line of Credit Facility [Abstract]
CreditFacilityDisclosure [Text Block]	Note 6. Credit Facilities We have a $500 million, five-year, unsecured revolving credit facility (the "Facility"), which expires in May 2018. The Facility is available for general corporate purposes including working capital, trade letters of credit, and standby letters of credit. The Facility fees fluctuate based on our long-term senior unsecured credit ratings and our leverage ratio. If we were to draw on the Facility, interest would be a base rate (typically LIBOR) plus a margin based on our long-term senior unsecured credit ratings and our leverage ratio on the unpaid principal amount. To maintain availability of funds under the Facility, we pay a facility fee on the full facility amount, regardless of usage. As of January 31, 2015, there were no borrowings and no outstanding standby letters of credit under the Facility. As of January 31, 2015, Standard & Poor's, Moody’s, and Fitch rate us at BBB-, Baa3, and BBB-, respectively. Any future change in the Standard & Poor’s or Moody’s ratings could change any future interest expense if we were to draw on the Facility. We maintain multiple agreements with third parties that make unsecured revolving credit facilities available for our operations in foreign locations (the “Foreign Facilities”). They are uncommitted and are generally available for borrowings, overdraft borrowings, and the issuance of bank guarantees. The total capacity of the Foreign Facilities was $49 million as of January 31, 2015. As of January 31, 2015, there were no borrowings under the Foreign Facilities. There were $11 million in bank guarantees primarily related to store leases under the Foreign Facilities as of January 31, 2015. We have a bilateral unsecured standby letter of credit agreement that is uncommitted and does not have an expiration date. As of January 31, 2015, we had $21 million in standby letters of credit issued under the agreement. We also have a $50 million, two-year, unsecured committed letter of credit agreement, which expires in September 2016. We had no trade letters of credit issued under this letter of credit agreement as of January 31, 2015. The Facility and the unsecured committed letter of credit agreement contain financial and other covenants including, but not limited to, limitations on liens and subsidiary debt, as well as the maintenance of two financial ratios—a minimum annual fixed charge coverage ratio of 2.00 and a maximum annual leverage ratio of 2.25. As of January 31, 2015, we were in compliance with all such covenants. Violation of these covenants could result in a default under the Facility and letter of credit agreement, which would permit the participating banks to terminate our ability to access the Facility for letters of credit and advances, terminate our ability to request letters of credit under the letter of credit agreement, require the immediate repayment of any outstanding advances under the Facility, and require the immediate posting of cash collateral in support of any outstanding letters of credit under the letter of credit agreement.

We have a $500 million, five-year, unsecured revolving credit facility (the "Facility"), which expires in May 2018. The Facility is available for general corporate purposes including working capital, trade letters of credit, and standby letters of credit. The Facility fees fluctuate based on our long-term senior unsecured credit ratings and our leverage ratio.

As of January 31, 2015, there were no borrowings and no outstanding standby letters of credit under the Facility.
