Net Book Value
The percentage of the average net book value of the sum of the segment’s tangible capital assets plus inventories to the total average net book value of such assets of all segments.
- (a) Verify that property held primarily for leasing to others is excluded.
- (b) Verify that inventories are net of progress payment billings.
- (c) Verify that inventories include work-in-process on fixed price contracts.
- (4) Determine that there are no double entries in the three factor formula (e.g., unbilled costs classified as revenue and inventory).
