Dr. Vilbert specializes in cost of capital, regulatory economics, financial planning, income tax disputes, and valuation.

He has advised clients on these matters in various investment and regulatory decisions. He divides his time between the firm’s Boston and San Francisco offices, working side-by-side with clients around the country.

His recent work has focused on evaluating the effects of various regulatory policy changes, such as decoupling of a company’s cost of capital and asset valuation in arbitration proceedings.

Dr. Vilbert has testified before the U.S. Federal Energy Regulatory Commission, the Canadian National Energy Board, numerous state and provincial regulatory commissions and boards, and in federal court. He has also assisted the U.S. Department of Justice and the U.S. Internal Revenue Service in a variety of complex tax litigation cases.

Representative Engagements
Development of a realized earnings test
Developed a test on behalf of FirstEnergy’s Ohio electric distribution companies consistent with Ohio’s legislation requiring an annual evaluation of the companies realized earnings. The purpose of the test is to determine whether the companies’ earnings were excessive. The test, which concluded that there were no excessive earnings, was accepted by the Public Utilities Commission of Ohio.
Cost of capital analysis for natural gas pipeline
Provided analyses for El Paso Natural Gas Pipeline before the Federal Energy Regulatory Commission regarding the cost of capital for the pipeline and the appropriate treatment of capacity not currently needed to provide service. Customers sought to deny the pipeline the opportunity to recover the costs of the unused capacity, but the Commission agreed with our analysis that the cost of the unused capacity should be allocated among the remaining shippers, consistent with the regulatory compact.
Report on the appropriate treatment of accrued depreciation
Provided a report on behalf of Progress Energy Florida, Inc., on the appropriate treatment of accrued depreciation expense for an asset whose expected life had been extended by 20 years. Report countered the request by intervenors to “reverse” the accrued deprecation. The report noted that the request would actually increase costs to customers in the long term and would likely lead to a credit rating decrease for the utility because of the reduction in cash flow. The Florida Public Service Commission denied the intervenor’s request.
Expert in a series of income tax shelter cases
On behalf of the Department of Justice and the Internal Revenue Service, served as the consulting expert in a series of income tax cases addressing tax shelter plans the IRS considered to be abusive and inconsistent with the underlying substance of the tax code. The DOJ and IRS won all cases.
