Completely accurate, appropriate, and comprehensive data are rarely available

An actuary performs an analysis with available data and sufficiently discloses material data limitations, and their implications

Data review may not always reveal imperfections

This standard does not recommend that an actuary audit data

Selection of Data

Understand intended use

Consider desired and possible alternative data elements

Data considerations:

Appropriate for intended purpose, including whether sufficiently current

Reasonableness and comprehensiveness

Known, material limitations

Cost and feasibility of alternatives

Sampling methods, if used

Review of Data

Definition of “review” added, pointing out that it is an informal examination of obvious characteristics of the data
