1. In FY 2008, the Department of Revenue made a change in the method by which it accounts for future revenues, as well as historical and future and oil prices, from a cash basis to an accrual basis. This method change will better align fiscal year revenues with the state’s financial reports and other production publications. As a result, slight modifications have been made to historical wellhead values to accommodate this change. This change was made to wellhead values on the tax division website on 6/30/2010.
