Interest rate description	Under terms of the amended revolving credit agreement, loans denominated in U.S. dollars bear interest, at the Company’s option, at either a base rate or a LIBOR-based rate. Loans denominated in currencies other than U.S. dollars bear interest at a LIBOR-based rate. The base rate is an annual rate equal to a margin ranging from zero percent to 0.875 percent, depending on the Company’s cash flow leverage ratio (debt to earnings before interest, taxes, depreciation, amortization and extraordinary non-operating or non-cash charges and expenses) plus the highest of (i) the bank’s prime rate, (ii) the federal funds rate plus 0.5 percent or (iii) one-month LIBOR plus 1.5 percent. In general, LIBOR-based loans bear interest at LIBOR plus 1 percent to 1.875 percent, depending on the Company’s cash flow leverage ratio.
