The committee found the mistakes related to the "reconciliation of income tax payable balances, accounting for uncertain tax positions and the impact of amending pre-acquisition legacy Epicor Software Corporation tax returns for our post-acquisition periods." Legacy refers to the company that operated before its acquisition by Apax Partners in 2011 and the combination of the former Epicor and former Activant. However, the committee in consultation with its auditor, KPMG, found the errors "do not impact previously reported revenues, pre-tax income or EBITDA." [Well, those are pre-tax, right?] CFO Kathy Crusco said the finding "will result in about $9 million that can be applied against future taxes."  The report also said the committee identified a material weakness in internal controls over reporting for income taxes. It said the controls were not "effective to ensure that amounts related to current taxes payable, certain deferred tax assets and liabilities, reserves for uncertain tax positions, the current and deferred income tax expense and related footnote disclosures were accurate." The committee hopes to complete a report by year's end.
