Wesco Distribution, Inc. – Contract No. 13421

We performed an audit of costs billed to the Tennessee Valley Authority (TVA) by Wesco Distribution, Inc., (Wesco) for operations materials and industrial equipment as part of TVA’s integrated supply program under master Contract No. 13421. Under the contract, TVA pays Wesco the established rates in the contract’s pricing schedules for inventory items that have a unique item number assigned. For items that were not established in the contract’s pricing lists or items that do not have a unique item number, TVA pays Wesco the cost of the item plus applicable markups established in the contract. Our audit objective was to determine if the costs billed to TVA under Contract No. 13421 were in accordance with the contract terms. Our audit scope included approximately $190.2 million in costs paid by TVA from January 1, 2021, through September 30, 2023. In summary, we determined Wesco overbilled TVA $149,246, including (1) $88,556 in unsupported costs, (2) a net $37,870 in costs for items whose rates billed exceeded the contract rates, and (3) $22,820 in costs for items that did not have a unique item number and whose rates billed exceeded the cost of the items plus applicable markups established in the contract. In addition, we determined several items should have been added to the contracts’ pricing lists based on how frequently they were purchased. Specifically, we identified 964 transactions with unique item numbers not on a contract pricing list, totaling $17,796,594, that were purchased four or more times in a year.
