Actuarial Standards of Practice: Key ASAPs

An overview of the most important Actuarial Standards of Practice that guide actuarial work.

What Are ASOPs?

Actuarial Standards of Practice (ASOPs) are promulgated by the Actuarial Standards Board (ASB) and define what constitutes acceptable actuarial practice in the United States. ASOPs apply to credentialed actuaries performing actuarial services and cover topics ranging from data quality to communication of results. Key ASOPs that every actuary should know include ASOP No. 1 (Introductory Standard), ASOP No. 23 (Data Quality), ASOP No. 25 (Credibility Procedures), ASOP No. 41 (Actuarial Communications), and ASOP No. 56 (Modeling). These standards establish minimum professional requirements but do not prescribe specific methodologies.

Practice-Specific Standards

Beyond the general ASOPs, practice-specific standards guide work in particular areas. ASOP No. 36 covers property/casualty loss reserve opinions. ASOP No. 43 addresses property/casualty unpaid claim estimates. ASOPs No. 22 and 51 address statements of opinion for life insurance. ASOP No. 4 governs pension actuarial work. Health actuaries follow ASOPs covering rate filings, risk adjustment, and health plan financial projections. Compliance with applicable ASOPs is not optional; it is a professional obligation enforced through the actuarial disciplinary process. Actuaries should regularly review updated and newly issued ASOPs to ensure their work remains compliant.
