# Quantitative and qualitative materiality

Evaluate financial errors using both their size and the context that may affect information users’ decisions.

 Principle · Accounting and finance


## Core concepts
  Quantity: examine amounts alongside relevant financial metrics
 Quality: examine implications such as trends or a profit-to-loss change
 Aggregation: distinguish individual errors from their combined effects
 

## Application
 Record amounts, comparison bases, qualitative factors and cumulative effects separately in review notes. Check applicable accounting standards and jurisdictional rules separately.


## Limitations and jurisdiction
 The source is US SEC staff guidance SAB 99 from 1999, not current Korean accounting or tax rules. No percentage is a safe harbor, and this does not replace an audit opinion.


## Editorial perspectives
  Numbers: keep comparison bases and calculations reproducible.
 Context: examine qualitative implications even for small amounts.
