Operating Activities

We rely primarily on cash flows from continuing operations to provide working capital for current and future operations. Cash flows from continuing operating activities totaled $120.9 million, $117.0 million and $145.8 million in 2005, 2004 and 2003, respectively. Cash inflows are primarily due to cash received from customers less cash paid to suppliers, employees and related parties. The increase in operating cash flows in 2005 as compared to 2004 was primarily due to an increase in net income. The decrease in operating cash flows for year ended December 31, 2004 as compared to 2003 was primarily due to a decrease in revenues partially offset by lower expenses and lower non-cash items included in net income.
