Model Validation Can Create Opportunities

Why should companies undertake model validation? Model validation adds credibility in the eyes of senior management

Allows for a thorough understanding of the strengths and limitations of existing processes, and identifies areas of possible remediation (errors, operational risks and/or inefficiencies)

Increases confidence that the results are “right”

A parallel model build in a different platform is a more robust/stronger statement for auditors than simply reviewing a model

9 PBR Boot Camp: Basic Training and Beyond for PBR Implementation September 21 - 23, 2016

Baselining

A fundamental first step to ensure ongoing compliance with validation requirements

Requires prioritization Much more time and resource consuming than the typical

model change validation activities Advantages of centralized resources to assist with baselining:

o Independence o Dedicated and scalable resources o Knowledge of typical and best practices o Experienced in developing audit approaches o Broader view model interaction across model owner groups

10 PBR Boot Camp: Basic Training and Beyond for PBR Implementation September 21 - 23, 2016

Types of Deliverables for Validation Effort

Overview of Models Including: Historical use Description of key risks (product, policyholder, market, operational, etc.) Description of methodology and assumptions Data flow and process maps, including data used and labeling of controls at various stages Report on Baselining Review: Justification for plan mapping and model compression (e.g., cell structure) Review of model inputs for product specifications and assumptions Application code review for intended purposes Appropriate use of reporting output Test sample illustrations Continued Monitoring: Model change documentation with reason, impacts, technical review, fit for purpose peer

review, and approvals

11 PBR Boot Camp: Basic Training and Beyond for PBR Implementation September 21 - 23, 2016

Continuation of Validation Controls

A formalized process for continuing validation controls after baselining Conduct in-line with model development lifecycle Examples: Separate testing environment for model changes Roll-forward analysis via a “waterfall” or “ladder” of results Maintenance of documentation suited to each model aspect Archive of current assumptions Model change documentation with levels of peer review and acceptance:

o Development o Technical Review o Testing Documentation o Peer Review o Model owner/management sign-off

Process is much easier to build upon the baseline deliverables

12 PBR Boot Camp: Basic Training and Beyond for PBR Implementation September 21 - 23, 2016

Best Practices

Start with models subject to highest risk o Materiality vs. complexity

Baselining of all inputs, formulas, and reports is more effective than ad hoc review on a narrower scope, which can be biased in terms of focus

The baseline report should stand on its own without the need to access the models (include work papers where needed)

Ensure independence during the review process, but obtain buy-in on findings from model owners

Cover the gaps between: o Initial generation of administration data and assumptions and inputs to the model o Model outputs to final delivery of results to stakeholders

13 PBR Boot Camp: Basic Training and Beyond for PBR Implementation September 21 - 23, 2016

Typical Areas of Major Findings

Misuse of data or results delivered between different areas of the company

Key risks ignored or insufficiently modeled

o Non-modeled business or features

o Lack of economic rate variation

Unexpectedly material simplifications

Model assumptions or approaches applied outside of actuarial guidelines or

recommended practices

Legacy practices or calculations invalidated by new events

Errors in back-end processes used in support of the primary projection model
