TOPEKA, Kan. (AP) – Gov. Sam Brownback has appointed the retired chief financial officer of an advertising and public relations agency to lead a review of the state’s revenue-projecting process.

Brownback announced Friday that Sam Williams of Wichita will help budget director Shawn Sullivan evaluating the forecasting process. The governor’s office also said Williams will help analyze tax policy.

The governor’s budget staff, Department of Revenue officials, legislative researchers and university economists issue revenue forecasts for state government twice a year. Tax collections have fallen short of their projections 10 of the past 12 months.

Williams is a former CFO for Sullivan Higdon & Sink who ran unsuccessfully for Wichita mayor in 2015. He also served as chairman of a task force set up in 2014 to look for efficiencies in public schools.
