Outlook and Overview Our operating requirements have historically been funded from cash flows generated from our business and borrowings under our credit facilities.
We expect that our future operating requirements will continue to be funded from cash flows from operating activities, existing cash and cash equivalents, and, if needed, from borrowings under our revolving credit facility and our ability to obtain future external financing.
