OCC revises exam guide booklet on sampling methodologies

A revised “Sampling Methodologies” exam guide booklet has replaced versions previously used in examinations of national banks, federal savings associations, and federal branches and agencies of foreign banking organizations, the Office of the Comptroller of the Currency (OCC) said in a bulletin Wednesday.

The booklet, included in the Comptroller’s Handbook, is used by OCC examiners in their examination and supervision work. The OCC said the revised booklet is effective for supervisory activities beginning on or after June 15.

According to OCC Bulletin 2020-56, the revised booklet:

  • explains the differences between statistical and judgmental sampling, including the appropriate use of each;
  • provides an updated and expanded discussion of judgmental sampling;
  • contains a detailed discussion of the OCC’s statistical sampling methodologies;
  • includes examples of the application of judgmental and statistical sampling; and
  • includes look-up tables for examiners to determine statistical sample sizes and upper confidence bounds.

The revised booklet replaces the booklet of the same title dated August 1998 and Office of Thrift Supervision Examination Handbook section 209, “Sampling.”
