From tracking ASB developments over the past several years, we can say with confidence that the current period represents the most intensive standard-setting cycle in the history of U.S. actuarial professionalism. The Actuarial Standards Board adopted five revised standards and one entirely new standard in 2024, approved seven exposure drafts for comment, continued development on six additional new or revised ASOPs, and approved a proposal to revise ASOP No. 1, the foundational introductory standard that defines how every other ASOP should be read and applied. Approximately 20 of the roughly 52 ASOPs currently in effect are being revised, with two additional new standards in development.

For practicing actuaries, this pace of change creates a genuine compliance challenge. The Code of Professional Conduct (specifically Precept 3 and its Annotation 3-1) requires every credentialed actuary to not only follow applicable standards but to keep current with changes. The Actuarial Board for Counseling and Discipline handled 12 inquiries in 2024 alone, with all seven resolved cases involving Precept 1 failures including inability to perform services with competence, and four involving work that failed to satisfy an ASOP.

This article provides a comprehensive guide to the ASOP landscape as of early 2026: which standards have recently changed, what major revisions are in progress, how the profession is responding to emerging challenges like generative AI and algorithmic bias, and what every actuary, from newly credentialed associates to senior fellows, should prioritize in their professional development.

The 2024 Adopted Standards: What Took Effect and When

The ASB's 2024 Annual Report documents an unusually productive year. Five revised ASOPs were adopted, alongside one landmark new standard. Understanding what changed and when is essential for compliance, since each standard's effective date determines when the new guidance becomes binding.

ASOP No. 29, Expense Provisions for Prospective Property/Casualty Risk Transfer and Risk Retention, was revised to broaden its scope. The updated standard now applies to actuaries performing services with respect to developing or reviewing expense provisions for all forms of prospective P&C risk transfer or risk retention, including insurance, reinsurance, self-insurance, and loss portfolio transfers. The revised standard more clearly differentiates between expense categories and stresses the importance of suitable models, methods, and assumptions. It also provides detailed guidance on considering the timing of residual market expenses. The effective date was July 1, 2024.

ASOP No. 28, Statements of Actuarial Opinion Regarding Health Insurance Assets and Liabilities, received scope clarifications to eliminate a conflict with ASOP No. 36. The revision states that other ASOPs may apply when an actuary issues opinions that include both health and non-health insurance assets and liabilities, providing clearer boundaries between the health and casualty opinion standards. The effective date was October 1, 2024.

ASOP No. 36, Statements of Actuarial Opinion Regarding Property/Casualty Loss, Loss Adjustment Expense, or Other Reserves, was expanded significantly. The scope now covers performing actuarial services with respect to a written opinion (not just issuing or providing one) and explicitly includes other reserves and reserves of property/casualty risk financing systems beyond traditional insurers. Section 4 was restructured with expanded disclosure requirements, particularly around the risk of material adverse deviation. The effective date was October 1, 2024.

ASOP No. 40, Compliance with the NAIC Valuation of Life Insurance Policies Model Regulation with Respect to X Factors, was updated to apply to all actuaries performing actuarial services related to Model compliance, rather than only the appointed actuary. The effective date was September 15, 2024.

ASOP No. 24, Compliance with the NAIC Life Insurance Illustrations Model Regulation, was revised to reflect changes from Actuarial Guideline 49-A and made consistent with current ASOP formatting. The revision went through three exposure drafts before adoption in September 2024, with an effective date of December 1, 2024.

Patterns we've seen across these revisions suggest the ASB is systematically broadening the scope of practice-area-specific standards while tightening disclosure requirements, a trend that aligns with increasing regulatory and public scrutiny of actuarial work product.

ASOP No. 58: A New Standard for Enterprise Risk Management

The most significant development in 2024 was the adoption of ASOP No. 58, Enterprise Risk Management, in December 2024, with an effective date of May 1, 2025. This is not merely a revision; it is an entirely new standard that replaces and repeals both ASOP Nos. 46 (Risk Evaluation in Enterprise Risk Management) and 47 (Risk Treatment in Enterprise Risk Management).

The original ERM standards were adopted in 2012, when actuarial practice in ERM was nascent and relatively few actuaries worked in dedicated risk roles. Since then, the field has evolved considerably. Many actuaries now serve as risk practitioners and some hold senior risk roles including chief risk officer. ERM nomenclature, frameworks, and regulatory expectations have similarly transformed, particularly with the NAIC's Own Risk and Solvency Assessment (ORSA) requirements.

ASOP No. 58 provides guidance on areas where the predecessor standards offered little or no direction, including governance over risk processes, risk identification, risk classification within an ERM framework, and considerations related to an organization's ORSA. The standard also aligns with ASOP No. 55, Capital Adequacy Assessment, which was adopted in 2019 and covers a topic with strong ERM connections.

The consolidation from two standards into one reflects a practical reality: risk evaluation and risk treatment activities are deeply intertwined, and separating them into distinct standards created artificial boundaries that did not match how ERM frameworks actually operate. The standard went through two exposure drafts, the first in May 2023 (receiving 15 comment letters) and the second in October 2024 (receiving three letters), before final adoption with no notable changes from the second draft.

Because ASOP No. 58 applies to all practice areas, the Academy's Applicability Guidelines were updated across all four practice-area tabs (casualty, health, life, and retirement) in late 2025. Any actuary performing services related to developing, maintaining, or reviewing all or part of an ERM framework must comply with the new standard for work performed on or after May 1, 2025.

The ASOP No. 41 Overhaul: The Profession's Most Consequential Pending Revision

If ASOP No. 58 is the biggest adopted change, the proposed revision of ASOP No. 41, Actuarial Communications, is arguably the most consequential revision still in progress. ASOP No. 41 is one of three "universal" standards (along with ASOP Nos. 1 and 23) that applies to virtually every actuarial assignment in every practice area. The current version, adopted in December 2010, has been in effect for over 15 years.

The ASB released a first exposure draft in June 2022, receiving 38 comment letters, an unusually high number that reflects the standard's universal applicability and the significance of the proposed changes. A second exposure draft was approved in October 2024, with the comment deadline extended from February 15 to March 15, 2025.

The key changes remaining in the second exposure draft include a restructured Section 4 where all required disclosures are consolidated and the treatment of deviations from any ASOP is codified. References to Prescribed Statements of Actuarial Opinion have been removed. Section 3.3.4 makes explicit that the actuary is responsible for all actuarial assumptions and methods used in producing the actuarial communication. Definitions have been improved to clarify the differences among actuarial communications, actuarial reports, and actuarial documentation, distinctions that the ABCD has noted cause confusion in practice.

The distinction between what applies to all actuarial communications versus what applies only to formal actuarial reports is particularly important. Informal communications (a quick email to a colleague, a Slack message with a preliminary estimate) are technically actuarial communications if they involve actuarial services. The revised standard aims to provide more proportionate guidance that recognizes the reality of modern actuarial communication while maintaining rigorous standards for formal reports.

From following the comment letters on the first exposure draft, the dominant concern was the apparent requirement for an actuary to complete an actuarial report with full disclosures in nearly all circumstances, a concern raised in 19 of the 38 letters. The second draft appears to address this by more clearly delineating when full report-level disclosure is necessary versus when lighter-touch communication is appropriate.

The task force chair transition (from Patricia Matson, who led the effort from inception through end of 2024, to Lisa Slotznick beginning January 2025) suggests the standard may take additional time before final adoption. Given the ASB's March 2026 meeting and the volume of second-round comments received, a final standard could potentially be adopted in mid-to-late 2026, though the timeline remains uncertain.

ASOP No. 12: Risk Classification Meets the AI Era

The proposed revision of ASOP No. 12, Risk Classification (for All Practice Areas), represents the profession's first major standard-setting response to the algorithmic and AI-driven transformation of risk classification. The original standard dates to 1989, with its most recent revision in 2005, before the widespread adoption of predictive modeling, machine learning, telematics, and the explosion of non-traditional data sources that now define modern risk classification practice.

The ASB approved an exposure draft in September 2023, with a comment deadline of May 1, 2024. The proposed revision includes several notable changes that directly address contemporary practice challenges.

New definitions have been added, including "risk measure" (replacing the existing focus on "expected outcomes" to reinforce that actuaries should consider aspects of the loss distribution beyond just the expected value) and "unintended bias," an emerging issue that requires actuaries to monitor how algorithmic outputs may produce classifications with discriminatory effects, even when the model inputs appear neutral.

A new Section 3.2.4 on Multivariate Effects acknowledges that modern risk classification frequently relies on complex models where the interaction between variables can produce effects not visible in univariate analysis. The previous standard, remarkably, did not contain the word "model" anywhere in its body, reflecting how dramatically practice has evolved since 2005.

Section 3.4, Potential for Unintended Bias, is entirely new and directly relevant to the growing regulatory focus on algorithmic fairness in insurance pricing. The NAIC's model bulletin on AI governance, the Colorado AI statute, and similar regulatory developments have created an environment where actuaries must consider whether their risk classification systems produce unintended disparate impacts. The revised ASOP No. 12 provides the professional framework for this analysis.

The task force received substantive comment letters from multiple sources, including the CAS, which provided detailed recommendations on aligning ASOP No. 12 with ASOP Nos. 53 and 56 to clarify the boundary between grouping risks into classes (ASOP No. 12) and estimating future costs for each class (ASOP No. 53). A second exposure draft or final adoption may follow, depending on the extent of revisions needed.

For actuaries working in predictive modeling, pricing, or underwriting, particularly those navigating the intersection of AI tools and regulatory scrutiny, this revision is one of the most important to watch. It establishes the professional standard of care for an area where regulatory expectations are evolving rapidly but the law remains unsettled.

ASOP No. 56 and Generative AI: Applying Existing Standards to New Technology

The rise of generative AI has prompted an important question for the profession: does the actuarial professionalism framework need a dedicated AI standard, or do existing standards adequately cover the territory?

The American Academy of Actuaries weighed in decisively with its October 2024 publication, "Actuarial Professionalism Considerations for Generative AI." The paper's central argument is that existing standards, particularly ASOP No. 56 (Modeling), ASOP No. 23 (Data Quality), and ASOP No. 41 (Actuarial Communications), apply directly to GenAI use in actuarial practice, even though they were developed before GenAI was widely available.

The logic is straightforward: GenAI is a model, and ASOP No. 56 provides guidance for actuaries when designing, developing, selecting, modifying, using, reviewing, or evaluating models. The standard requires actuaries to select and use models that reasonably meet their intended purposes, to understand known weaknesses in assumptions and methods, and to validate model outputs before relying on them.

The Academy paper identifies several critical professionalism considerations. An actuary cannot use a GenAI result without validation and simply attribute the output to the model. ASOP No. 56 requires conclusions to be supported with sufficient validation testing and analysis. When an actuary has limited ability to understand how a model developed by others works (as is often the case with large language models), the standard requires the actuary to make a reasonable attempt to gain a basic understanding and to make practical efforts to comply with the standard's other provisions.

ASOP No. 23 enters the picture through data quality requirements. AI models may incorporate biased training data or produce outputs that reflect biases not present in the actuary's input data. The standard's requirement to review data for reasonableness and consistency takes on new dimensions when the "data" includes AI-generated content.

The SOA Research Institute's January 2026 AI Bulletin posed the question directly: does the profession need an AI-specific ASOP, a near-term update of existing relevant ASOPs, or can it rely on professionalism standards as-is while referencing other resources? The ASB has not yet signaled intent to develop a dedicated AI standard, suggesting the current approach, relying on ASOP Nos. 56, 23, and 41 supplemented by guidance documents, will prevail for the near term. However, the rapid pace of AI evolution means this position could shift quickly.

For practitioners, the practical takeaway is clear: if you use GenAI tools in your actuarial work, whether for coding, research, summarization, or analysis, you bear the same professional responsibility for the output as you would for any model. Documentation of how AI was used, what validation was performed, and what limitations were identified is not optional.

The Casualty Pipeline: ASOPs 20, 30, and 39

The ASB's Casualty Committee has been particularly active, with three major standards in various stages of revision that will reshape guidance for P&C actuaries.

ASOP No. 39, Treatment of Catastrophe or Extreme Event Losses, is being revised with a new title: "Treatment of Catastrophe or Extreme Event Losses in Future Cost Estimates for Property/Casualty Risk Transfer and Risk Retention." The exposure draft, approved in December 2024, had its comment deadline extended from May 1 to June 1, 2025. The revision modernizes guidance for an era of escalating catastrophe frequency, evolving cat model sophistication, and the increasing role of secondary perils like wildfire and convective storms.

ASOP No. 30, Profit Margins and Contingency Provisions, has been retitled "Profit Margins and Contingency Provisions in Property/Casualty Risk Transfer and Risk Retention." The exposure draft was approved in June 2024, and the task force is now addressing comments received during the exposure period. The revision provides expanded guidance on developing profit margins and contingency provisions associated with future cost estimates, including treatment of cost of capital, a topic of increasing importance in casualty ratemaking as social inflation and climate risk elevate the capital requirements for long-tail and catastrophe-exposed lines.

ASOP No. 20, Analysis of Property/Casualty Cash Flows, Including Discounting, represents one of the most significant scope expansions in the current cycle. The ASB decided in 2024 to remove P&C actuarial practice from the scope of ASOP No. 7, Analysis of Life, Health, and Property/Casualty Insurance Cash Flows, and to consolidate all P&C cash flow guidance in a revised ASOP No. 20. The expanded scope now covers any P&C cash flow model, discounted or undiscounted, including non-loss cash flows such as premiums, underwriting expenses, and other items. The exposure draft, approved in March 2025, has a comment deadline of August 1, 2025.

Together, these three revisions will substantially update the guidance framework for P&C actuaries across ratemaking, reserving, and financial analysis functions. Casualty actuaries should plan to review all three exposure drafts and consider submitting comments; the ASB's comment process is one of the profession's most important mechanisms for ensuring that standards reflect actual practice.

Life, Health, and Retirement Pipeline

The standard-setting activity extends well beyond casualty practice.

ASOP No. 7, Analysis of Life, Health, or Property/Casualty Insurance Cash Flows, is being revised to reflect the removal of P&C practice from its scope, with a task force continuing work through 2025.

A new ASOP on Pricing Reinsurance, formally titled "Pricing Reinsurance or Similar Risk Transfer Transactions Involving Life Insurance, Annuities, or Long-Duration Health Benefit Plans," addresses a significant gap in the standards. ASOP No. 54 (Pricing of Life Insurance and Annuity Products) explicitly excludes reinsurance pricing from its scope, and ASOP No. 11 covers only financial reporting aspects of reinsurance. The proposed new standard covers pricing from the assuming entity perspective, including guidance on pricing-related activities such as administration, treaties, and post-initial pricing activities like monitoring and nonguaranteed element management. The exposure draft was approved in June 2024 with a comment deadline of November 1, 2024. The task force is now addressing comments received.

ASOP No. 6, Measuring Retiree Group Benefits Obligations, is being revised, with a task force developing a proposed revision to update guidance for the current retiree benefits environment. The exposure draft was approved with a comment deadline of May 15, 2026, reflecting the standard's complexity and the need for extensive stakeholder input.

ASOP No. 45, The Use of Health Status Based Risk Adjustment Methodologies, is also under revision by a task force of the ASB's Health Committee, responding to the evolving landscape of risk adjustment in healthcare, particularly as ACA risk adjustment methodologies and Medicare Advantage risk scoring face ongoing regulatory changes.

ASOP No. 1, Introductory Actuarial Standard of Practice, will also be revised, with the ASB approving a proposal in 2024 to update this foundational document. Any revision to ASOP No. 1 has implications for how all other ASOPs are interpreted, since it defines key terms like "should," "must," "may," "materiality," "reasonable," and "professional judgment" that appear throughout the entire body of standards.

Disciplinary Trends: What the ABCD Data Shows

The disciplinary side of the professionalism framework provides a sobering complement to the standard-setting activity. The ABCD handled 12 inquiries in 2024, based on complaints or adverse information. Of the seven resolved cases, all involved Precept 1, notably failure to perform services with competence and failure to uphold the profession's reputation. Four inquiries involved failure to act with integrity and work that failed to satisfy an ASOP. Two involved performing work when not qualified, and one involved inadequate or inappropriate actuarial communication.

The outcomes included two dismissals, two dismissals with guidance, two instances of counseling, and one recommendation of discipline to the relevant membership organizations. While these numbers are small relative to the total credentialed population, they represent meaningful consequences for the individuals involved and serve as a reminder that ASOPs are enforceable standards, not aspirational guidelines.

The ABCD emphasizes that many inquiries involve multiple Code precepts simultaneously: a data quality problem (ASOP No. 23) may also reflect a communication failure (ASOP No. 41) and raise questions about competence (Precept 1). Actuaries who invest time in understanding how standards interrelate, rather than viewing each ASOP in isolation, are better positioned to avoid compliance gaps.

What This Means for Practitioners: A Priority Framework

Given the volume of changes, actuaries need a practical framework for staying current. Three categories of prioritization emerge from the current landscape.

Immediate compliance requirements: Standards adopted with past effective dates require immediate attention. These include the five 2024 revisions (ASOPs 24, 28, 29, 36, and 40) and ASOP No. 58, which became effective May 1, 2025. Actuaries performing work covered by these standards should confirm they are using the current version and have adjusted their documentation, disclosure, and methodology practices accordingly.

Active monitoring: Exposure drafts currently open for comment or recently closed represent the near-term future of the standards. ASOPs 6, 20, 30, 39, and 41 all have exposure drafts in various stages. Reviewing these drafts, and particularly submitting comments, is both a professional responsibility and an opportunity to influence standards that will govern practice for years.

Strategic awareness: The broader trends in standard-setting (expanding scope, tightening disclosure, addressing AI and algorithmic fairness, consolidating overlapping guidance) signal the direction the ASB is taking. Actuaries who understand these trends can anticipate future requirements and proactively adjust their practice.

For exam candidates, particularly those on the CAS track approaching Exams 5 through 9, ASOP knowledge is directly tested and increasingly relevant. The interplay between social inflation and reserving standards (ASOP No. 36, No. 43), between AI adoption and modeling standards (ASOP No. 56), and between climate risk and catastrophe standards (ASOP No. 39) provides rich context for understanding why standards exist and how they evolve with practice.

The Academy's downloadable Applicability Guidelines (an Excel spreadsheet with a tab for each practice area) remains one of the most useful tools for quickly identifying which standards apply to specific assignments. The guidelines were most recently updated in late 2025 to reflect ASOP No. 58 and several other recently adopted revisions.
