Employer jurisdiction Identification of incorporation) Number) 600 Grant Street Pittsburgh, PA 15219 (Address of principal (Zip Code) executive offices) Registrant's telephone number, including area code: (412) 456-4400 (Former name or former address, if changed since last report.) Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below): [ ] Written communications pursuant to Rule 425 under the Securities Act (17 CFR 230.425) [ ] Soliciting material pursuant to Rule 14a-12 under the Exchange Act (17 CFR 240.14a-12) [ ] Pre-commencement communications pursuant to Rule 14d-2(b) under the Exchange Act (17 CFR 240.14d-2(b)) [ ] Pre-commencement communications pursuant to Rule 13e-4(c) under the Exchange Act (17 CFR 240.13e-4(c)) Item 4.02(a) Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review Subsequent to the issuance of the Corporation's consolidated financial statements for the year ended December 31, 2004, the Corporation concluded: (1) based on supplemental guidance recently issued, that auction- rate securities do not meet the definition of cash equivalents and should therefore be classified as short-term marketable securities, and (2) its outstanding Industrial Revenue Bond debt should be classified as a current liability, despite principal not beginning to become due until 2020, since the bonds can be put back to the Corporation on short notice if, although considered remote by the Corporation, the bonds are unable to be remarketed and bondholders seek reimbursement from the letters of credit which serve as collateral for the bonds. Any payments under the letters of credit are required to be repaid by the Corporation immediately. The effect of reclassifying its investments in auction-rate securities from cash and cash equivalents to short-term marketable securities and its Industrial Revenue Bond debt from a long-term liability to a current liability on the consolidated balance sheets as of December 31, 2004 and 2003 and the consolidated statements of cash flows for the years ended December 31, 2004 and 2003, is indicated below. The Corporation did not invest in auction-rate securities prior to 2003. 2004 2003 As As Previously As Previously As Reported Restated Reported Restated (in thousands) Consolidated Balance Sheets as of December 31,: Cash and cash equivalents $36,795 $11,340 $35,739 $15,489 Short-term marketable securities - 25,455 - 20,250 Total current liabilities 41,170 54,481 34,042 47,353 Long-term debt obligations 13,311 - 13,311 - 2004 2003 As As Previously As Previously As Reported Restated Reported Restated (in thousands) Consolidated Statements of Cash Flows for the Year Ended: Purchases of short-term marketable securities $ - $(48,635) $ - $(51,250) Proceeds from the sale of short-term marketable securities - 43,430 - 31,000 Net cash flow (used in) provided by investing activities (5,111) (10,316) 6,863 (13,387) Net increase (decrease) in cash and cash equivalents 1,056 (4,149) 7,950 (12,300) Cash and cash equivalents at beginning of period 35,739 15,489 27,789 27,789 Cash and cash equivalents at end of period 36,795 11,340 35,739 15,489 Management, including the principal executive officer and the principal financial officer, of the Corporation have evaluated the implications of these changes on the Corporation's internal control over financial reporting and have concluded that a material weakness in the Corporation's internal control over financial reporting with respect to classification of the Industrial Revenue Bond debt (redeemable instruments that are subject to remarketing agreements) existed but has been since been remediated. The remedial actions taken included: - Requiring all future debt agreements to be reviewed by the finance department for proper balance sheet classification. - Improving understanding of relevant personnel of the requirements of EITF D-61, "Classification by the Issuer of Redeemable Instruments That Are Subject to Remarketing Agreements". The Audit Committee of the Corporation's Board of Directors and management concluded on May 11, 2005, that the previously issued consolidated financial statements and related auditors' reports for the years ended December 31, 2004 and 2003 should not be relied upon because of the aforementioned errors in those consolidated financial statements. The Corporation intends to file an amendment on Form 10- K/A to its Annual Report to Shareholders on Form 10-K for the year ended December 31, 2004, as soon as practicable. The Audit Committee of the Corporation's Board of Directors and management have discussed the matters disclosed in this Current Report on Form 8-K with the Corporation's independent registered public accounting firm, Deloitte & Touche, LLP.
