ITEM 6. SELECTED FINANCIAL DATA

        The selected historical financial data presented below are derived from our consolidated financial statements. The selected financial data should be read in conjunction with Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements and the notes thereto included elsewhere in this report.

(1)

Our results for the year ended December 31, 2002 include only six days of activity of Advanced Circuits, Inc., which we acquired on December 26, 2002. A full year of activity at this subsidiary is included in our results for the year ended December 31, 2003. In both 2002 and 2003, we recorded extraordinary gains related to this acquisition. See Note 3 to our consolidated financial statements included herein.

(2)

In 2002, we adopted Statement of Financial Accounting Standards ("SFAS") No. 142, "Goodwill and Intangible Assets" and ceased amortizing goodwill. Our expense in 2002 and 2003 reflects amortization of intangibles related to our acquisition of Power Circuits in July 1999. See Note 2 to our consolidated financial statements included herein.

(3)

We recorded restructuring charges in 2002 and 2003 related to the closure of our Burlington, Washington, facility. The charge in 2002 is composed primarily of severance expense and other cash exit costs as well as non-cash expenses to write down the value of the building and equipment held for sale. The charge in 2003 was to further write down the value of the building and equipment. See Note 4 to our consolidated financial statements included herein.

EBITDA means earnings before interest expense (including amortization of debt issuance costs), income taxes and depreciation and amortization. However, EBITDA should not be considered as an alternative to cash flows from operating activities as a measure of liquidity or as an alternative to net income as a measure of operating results in accordance with accounting principles generally accepted in the United States. Our definition of EBITDA may differ from definitions used by other companies. The following is a reconciliation of net income (loss) to EBITDA for each period presented:
