The Accounting standards for inventory is 10 pages in both
Accounting Standards for Private Enterprises (ASPE) and
International Financial Reporting Standards (IFRS). If we
compare this to the number of pages for financial instruments, 60
pages in ASPE, and 130 pages in IFRS, it is easy to assume that
inventory costing is simple.
Less Words Mean More Judgment
Inventory accounting standards are written based on principles
versus with financial instruments using rules. Rules based
accounting is explicit and requires more words to tell people how
to apply them. The difference between the two sections is
like black and white versus shades of gray.
The principles based inventory accounting standards gives
companies options (considered accounting policy choices) on how it
records its inventory.
