Debt disclosure
Debt disclosure [Text Block]	7. DEBT Debt Payment. On March 15, 2013, the Company’s $500 million, 5.00% senior notes matured and were fully paid. Credit Agreement. On June 7, 2013, the Company entered into a five-year, $1.0 billion revolving credit agreement with a syndicate of financial institutions, replacing its three-year $1.0 billion credit agreement that was due to expire on June 10, 2013. Pursuant to the credit agreement covenants, the Company must maintain a minimum consolidated net worth, defined as shareholders’ equity determined in accordance with GAAP plus (a) trust preferred securities (not to exceed 15% of total capital) and (b) mandatorily convertible securities (combined with trust preferred securities, not to exceed 25% of total capital) less goodwill and other intangible assets. That threshold is adjusted downward by an amount equal to 70% of the aggregate amount of common stock repurchased by the Company after March 31, 2013, up to a maximum deduction of $1.75 billion. The threshold was $15.27 billion at June 30, 2013 and could decline to a minimum of $13.73 billion during the term of the credit agreement, subject to the Company repurchasing an additional $2.20 billion of its common stock. In addition, the credit agreement contains other customary restrictive covenants as well as certain customary events of default, including with respect to a change in control, which is defined to include the acquisition of 35% or more of the Company’s voting stock and certain changes in the composition of the Company’s board of directors. At June 30, 2013, the Company was in compliance with these covenants. Generally, the cost of borrowing under this agreement will range from LIBOR plus 87.5 basis points to LIBOR plus 150 basis points, depending on the Company’s credit ratings. At June 30, 2013, that cost would have been LIBOR plus 112.5 basis points, had there been any amounts outstanding under the credit agreement. This credit agreement also supports the Company’s commercial paper program.
