- The line
- Every asset filed once with its cost, its dates, its holder and where it is The accountant's fixed asset schedule, the IT manager's laptop list and the office's furniture inventory are usually three files that disagree about the same things. One register line per asset, with the holder and the location on it, is what lets one person answer what the organization owns without a meeting.
- The period
- Depreciation run each period from the line, not rebuilt each January Straight-line and declining-balance depreciation are arithmetic on the cost, the salvage value and the useful life already on the line. Running it each period from the register, and keeping every period's figure, is what turns the year-end fixed asset report into a print rather than a reconstruction.
- The count
- Every disposal, transfer and physical count recorded with a date against it The register is only worth what it says on the day someone checks it. A disposal with its date and proceeds, a transfer with its new holder, and a physical count with what was found and what was not, kept against the line, are what an auditor, an insurer or a grant officer asks to see.
