The $983 million decrease in unbilled power receivables and the $876 million increase in billed receivables are primarily due to the implementation of a new wholesale base rate structure for the majority of TVA’s customers on April 1, 2011. Under the previous end-use billing structure, billed sales were reported a month in arrears. Under the new wholesale base rate structure, customers are billed in the current month.
