File-and-Use

A regulatory framework allowing insurers to use new rates or forms immediately upon filing, without waiting for approval—subject to later department review.

FAQs

What is the difference between file-and-use and use-and-file?
In file-and-use, the filing must be submitted before or simultaneously with implementation—the filing precedes use. In use-and-file, the carrier may begin using rates or forms before submitting the filing, which must occur within a defined retroactive window (often 30–90 days after implementation). File-and-use provides a slightly higher level of regulatory oversight since the department has the filing in hand from day one of implementation.
Can a carrier in a file-and-use state continue using rates after receiving a withdrawal order?
No—a withdrawal order legally prohibits further use of the withdrawn rates or forms. The carrier must comply with the order prospectively (stopping use for new and renewed policies) and follow any retroactive adjustment requirements. Continued use of withdrawn rates after a withdrawal order is a serious regulatory violation that can result in substantial penalties and enforcement action.
How quickly should a carrier respond to a department deficiency letter on a file-and-use submission?
Deficiency letters typically specify a response deadline (30 to 60 days in most states). Timely, complete responses are important—failure to respond can result in the department issuing a withdrawal order without further engagement. For complex technical objections, carriers should engage their actuarial and regulatory teams immediately. If more time is needed, most departments will grant extensions if asked before the deadline.

Related Terms

  • Prior Approval

    A state regulatory framework requiring insurers to obtain explicit department approval before implementing new rates or forms—the most restrictive approach.

  • Use-and-File

    A regulatory framework allowing insurers to implement new rates or forms before filing them, with retroactive filing required within a specified period.

  • Rate Filing

    The formal submission of insurance premium rates, rating factors, and actuarial documentation to the state insurance department before charging those rates.

  • Algorithmic Bias

    Systematic unfair discrimination in AI or ML models disadvantaging protected classes—a critical compliance concern as insurers adopt predictive models.

File-and-use is a rate and form regulatory model under which an insurance carrier may implement new rates or begin using new policy forms as soon as the filing is submitted to the state insurance department—without waiting for explicit approval. The department reviews the filing after it is in use and retains authority to issue a withdrawal order if it finds the rates or forms non-compliant.

How It Works / Why It Matters

File-and-use represents a middle ground between prior approval (which prohibits implementation before approval) and use-and-file (which allows implementation before filing). Under file-and-use, the carrier must complete and submit a proper filing before implementing—the filing is a prerequisite to use, but the department's affirmative approval is not.

The filing must still meet all substantive requirements: actuarial support for rates, statutory compliance for forms, required documentation, and proper submission through SERFF. The difference from prior approval is procedural and temporal—use begins simultaneously with submission rather than after a regulatory waiting period.

Regulatory review post-implementation: The department reviews file-and-use submissions in the ordinary course and may issue a withdrawal order at any time after submission. A withdrawal order requires the carrier to stop using the form or rate prospectively and, in some states, may require retroactive adjustments for policies already written at the non-compliant rate. The threat of retroactive withdrawal creates incentive for carriers to submit compliant, well-supported filings even in file-and-use states.

Which states use file-and-use: Many states use file-and-use for commercial lines even when personal lines are subject to prior approval. Some states apply file-and-use across all lines. The model is particularly common for commercial automobile, general liability, and property lines in states that view commercial insurance buyers as sophisticated parties capable of protecting their own interests.

In Practice

A commercial property carrier wants to revise its rating plan for retail businesses—adjusting classification factors and adding a new surcharge for specific construction types. In a file-and-use state, the carrier's actuarial and regulatory team prepares the rate filing with complete documentation, submits through SERFF, and simultaneously implements the new rates in its policy administration system. New policies and renewals written on or after the implementation date are rated under the new plan.

The department receives the filing in its queue and assigns it for review. If the reviewer finds an issue—say, the actuarial support for a specific surcharge is insufficient—the department sends a deficiency letter. The carrier responds with additional support, and if the response resolves the issue, the filing stands. If the department finds a fundamental problem, it issues a withdrawal order.

AI-driven rate models: AI-driven rate models present documentation challenges in file-and-use states. If an AI model generates rates that the carrier cannot adequately explain after the fact—particularly if a withdrawal order requires justification of specific rate levels—the carrier faces regulatory exposure. This connects to the broader algorithmic-bias and ai-model-governance compliance requirements that increasingly require explainable pricing.
