Accounting research has shown that the distinction between
rules-based and principles-based standards is not well defined and is subject
to a variety of interpretations. Nonetheless, there is a commonly-held view
that accounting standards in the United States are rules-based and
International Financial Reporting Standards (IFRS) issued by the International
Accounting Standards Board (IASB) are principles-based.
A research paper published in 2006 identifies the basis of
this distinction. For research and development, the paper compares the US
standard issued by the Financial Accounting Standards Board (FASB) with two
principles-based standards. For each standard, the researchers identify and
classify rules and judgments, and observe the level of justifications for the
rules and assistance to support the judgments. The three standards have rules,
are based on principles, and require the exercise of professional judgment; the
less conservative standard requires more judgments and, unexpectedly, more
rules.
The results suggest that the rules-based versus
principles-based distinction is not meaningful, except in relative terms. The
paper concludes that a relatively more principles-based standards regime
requires professional judgment at both the transaction level (substance over
form) and at the financial statement level (‘true and fair view’ override).
Furthermore, it suggests that any IASB and FASB convergence will require
agreement on the weightings given to the qualitative characteristics.
