Section 8 - Other Items
           Item 8.01 Other Items

The Company issued a press release on June 2, 2005 which announced it has received a report from the Internal Revenue Service (the "IRS") requesting downward adjustments of approximately $33 and $37 million to ISC's tax depreciation expense for the fiscal years ended November 30, 1999 and 2000, respectively. Additional adjustments to the Company's tax depreciation expense are expected to be requested later by the IRS for fiscal years ended November 30, 2001 through 2004.

Based on the federal income tax statutory rate of 35%, the combined requested reduction of tax depreciation expense for the fiscal years ended November 30, 1999 and 2000, would result in the reclassification of approximately $25 million of tax expense from deferred to current. Including related interest, the combined after-tax cash flow impact of the requested adjustments will be approximately $33 million. The Company disagrees with the IRS' position and expects to proceed to the administrative appeals process within the IRS.

A copy of the press release is attached as an exhibit.
