Long-term Debt [Text Block]	5. LONG-TERM DEBT Our long-term debt includes $300 million of 3.61 percent senior notes due in 2024, $600 million of 4.658 percent senior notes due 2044, and $400 million of 4.5 percent senior notes due 2048. The indenture governing our Senior Notes includes an event of default upon the acceleration of other indebtedness of $100 million or more. Such events of default would entitle the trustee or the holders of 25 percent in aggregate principal amount of the outstanding Senior Notes to declare those Senior Notes immediately due and payable in full.
