Debt	5. DEBT Watsco Revolving Credit Agreement We maintain a bank-syndicated, unsecured revolving credit agreement that provides for borrowings of up to $300,000. Borrowings are used to fund seasonal working capital needs and for other general corporate purposes, including acquisitions, dividends, stock repurchases and issuances of letters of credit. Included in the facility are a $25,000 swingline subfacility and a $50,000 letter of credit subfacility. Borrowings bear interest at primarily LIBOR-based rates plus a spread which ranges from 37.5 to 112.5 basis-points depending upon our ratio of total debt to EBITDA (LIBOR plus 40 basis-points at December 31, 2011). We pay a variable commitment fee on the unused portion of the commitment, ranging from 7.5 to 20 basis-points (8 basis-points at December 31, 2011). Alternatively, we may elect to have borrowings bear interest at the Prime Rate or the Federal Funds Rate plus our spread.
