Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	DebtAs of September 30, 2022, we had $12,000 currently available under credit line agreements. In the third quarter of 2022, we entered into a $5,800 364-day revolving credit agreement expiring in August 2023, a $3,000 three-year revolving credit agreement expiring in August 2025, and amended our $3,200 five-year revolving credit agreement, which expires in October 2024, primarily to incorporate a LIBOR successor rate. The 364-day facility has a one-year term out option that allows us to extend the maturity of any borrowings one additional year. We continue to be in full compliance with all covenants contained in our debt or credit facility agreements.
