Rules-based accounting is basically a list of detailed rules that must be followed when preparing financial statements. Many accountants favor the prospect of using rules-based standards, because in the absence of rules they could be brought to court if their judgments of the financial statements were incorrect. When there are strict rules that need to be followed, the possibility of lawsuits is diminished. Having a set of rules can increase accuracy and reduce the ambiguity that can trigger aggressive reporting decisions by management. The complexity of rules, however, can cause unnecessary complexity in the preparation of financial statements.
