FOCUS ON WORKING CAPITAL MANAGEMENT AND CASH FLOWS

Cash flows provided by operating activities were $11.1 million during fiscal 2009, compared to cash flows provided by operating activities of $27.9 million during fiscal 2008. Our debt less cash as of the end of fiscal 2009 was $8.5 million, a $7.1 million improvement, compared to $15.6 million at the end of fiscal 2008.

“Despite the continuing challenges of the global economy, we were able to generate positive cash flow during the year. Our balance sheet continues to be the strongest it has been in years. We will continue to manage working capital to ensure we have adequate flexibility and liquidity to manage our business,” said Kathleen S. Dvorak, Executive Vice President and Chief Financial Officer.

During the fourth quarter, the Company did not repurchase any shares of its common stock under its share repurchase program. The share repurchase program was approved by the Company’s Board of Directors in January 2009. The share repurchase program does not have an expiration date and may be cancelled at any time.

OUTLOOK

“While sales have declined, we are beginning to see our backlog stabilize, our customers are becoming more optimistic, and we are seeing pockets of good news in terms of projects that are getting back on track. We are continuing to aggressively take costs out of the business. We are making permanent fundamental changes to the way we operate that will position us to return to profitability during fiscal 2010,” concluded Mr. Richardson.
