For those interested in the details the formula would be:
Number of notional partners equals partner work on the matter (hours times standard billing rates) as a percentage of total partner work for the firm, times the total number of partners.
Direct expenses for the matter includes compensation and benefits of timekeepers on the matter (including an assumed compensation for partners), allocated in proportion to the hours spent on the matter vs. the timekeeperÕs total hours for the year. Allocable indirect expenses include occupancy expense, compensation and benefits of non-timekeeper staff, insurance, etc. Allocation methods will vary based on the type of expense. The firmÕs software handles all this.
