NEW ACCOUNTING STANDARDS AND INTERPRETATIONS In 2010, the FASB amended the Receivable Topic of the FASB Accounting Standards Codification to enhance disclosures about the credit quality of financing receivables and the allowance for credit losses. The update amends existing disclosures to require an entity to provide a greater level of disaggregated information about the credit quality of its financing receivables and its allowance for credit losses. The amendment also requires an entity to disclose credit quality indicators, past due information, and modifications of its financing receivables. The amendment is effective for interim and annual reporting periods ending on or after December 15, 2010. FirstEnergy is currently evaluating the impact of adopting this standard on its financial statements 11.
