Planning a rate change: from indication to effective date

What drives the timeline

Five things decide how early work has to start:

• The rating law in each state. Under prior approval, rates cannot be used until approved, by order or through a deemer provision. Under file and use they can be used once filed, and under use and file they are filed after use. The NAIC handbook also describes flex rating, where prior approval applies only to changes beyond a set percentage. See rate regulation systems.
• Review and objection time. How long a reviewer takes, and how many rounds of objections the filing draws, varies by state and filing.
• Public process. Some states give public notice of rate applications and allow hearings. California, for example, must notify the public of a rate application under Proposition 103 and may hold a hearing. See rate hearings and public input.
• Notice lead times. Renewal notice rules set how far ahead of a renewal date the new premium must be communicated.
• Implementation. Rating engine changes, testing and form and document updates have their own lead time inside the company.

Data and the indication

The indication is the actuarial estimate of the rate change needed. Its timing depends on the experience period, data extraction and validation, trend and development selections, and any catastrophe or reinsurance cost inputs. Two planning decisions matter here:

• The experience period and evaluation date. Pick these knowing the filing will be reviewed months later. A reviewer may ask why more recent data was not used.
• The target effective date. Trend and on-level calculations are projected to the period the rates will be in effect, so the indication assumes an effective date. If the filing slips, the projection may need updating.

The actuarial memorandum and rate filing exhibits describe what the indication must show.

Selection and internal approval

The NAIC handbook notes that the indicated change should be the company's best estimate of its premium needs, but that companies weigh competition, marketing, legal concerns and retention, and may select a different change if they justify the departure within the law. Selection decisions that take time include:

• the overall change by state and by program;
• the distribution of the change across coverages, territories and rating variables;
• capping or transition rules where the state permits them. The handbook lists questions such as which rates to cap, whether decreases are capped and how many renewal cycles the transition will take;
• underwriting or rule changes that accompany the rate change.

Build in time for each internal approval: actuarial peer review, pricing committee, product management, compliance and any executive sign-off. A late change in selection usually means reworking exhibits, rate pages and the memorandum together.

Building the filing

Each state's filing is assembled to that state's requirements: required exhibits and forms, the state's checklist, rate and rule pages, the memorandum, policyholder impact distributions and the SERFF rate summary fields. State filing requirements and checklists covers where those requirements are published. If forms or rules change too, the related form or rule filing should be planned with matching dates. The NAIC handbook notes that form and rate reviewers may need to coordinate so that rate, rule and form filings take effect consistently.

Sequencing across states

A multistate rate change is a set of separate filings, one per state, each with its own clock. Common ways to sequence them:

• Longest lead time first. File first where approval or public process takes longest, so all states can reach their effective dates.
• Group by rating law. File-and-use and use-and-file states can often take effect on a planned date; prior approval states depend on the disposition.
• Stagger by renewal volume. Some carriers spread implementation to manage system and service workload.
• Watch for dependencies. A rule or form change that applies in several states may need every state's version approved before a shared system release.

Keep one tracker per state with the filing date, disposition date, approved effective dates and notice deadlines. Amendments in one state's filing do not carry over to the others.

Submission, review and objections

After submission, the reviewer checks completeness, then substance. Objection letters are the normal way questions arrive, and the speed and completeness of responses are the largest part of review time the filer controls. See SERFF objections.

State deadlines can be strict. In California, the Department of Insurance describes its process for Proposition 103 lines: public notice within ten days of receiving the filing, a 45-day window for a hearing request, and a 60-day period after notice to approve or issue a notice of hearing, after which the filing is deemed approved. Under Insurance Code § 1861.05(c), a rate application is deemed approved 180 days after receipt unless disapproved after a hearing or extraordinary circumstances exist. Check the current law and practice in each state; deemer provisions and how objections affect them vary.

Disposition and implementation

The disposition records what the state allowed: approval as filed, approval with modifications, partial withdrawal or disapproval. Implementation should use the final approved rate pages, not the original submission. Typical steps:

• update the rating engine, rate tables and rules, and test against the approved pages;
• update quoting, policy administration and billing systems;
• update forms, declarations, notices and agent materials;
• confirm the effective-date logic for new business and renewals in each state;
• reconcile written premium after implementation with the filed impact.

New business and renewal effective dates

Many filings state separate effective dates for new business and for renewals. The renewal date is often later, to allow for notice and for policies already quoted or offered. When planning:

• define precisely which policies the change applies to, such as policies effective on or after a date, or renewals processed on or after a date;
• set the renewal date with the longest applicable notice requirement in mind;
• describe the rule on the SERFF rate summary and in the filing so the reviewer and the systems team read it the same way.

Policyholder notice

States regulate notice of nonrenewal and, in some cases, advance notice of the renewal premium or of a premium increase. Requirements vary by state and line in lead time, content, delivery method and who must receive the notice. Florida's statute is one example: for many property, casualty and workers' compensation policies, it requires at least 45 days' advance written notice of nonrenewal or of the renewal premium to the first-named insured, with exceptions and separate rules for motor vehicle insurance. It also extends coverage if the insurer fails to give the required notice.

Work backward from the renewal effective date. The notice lead time, plus time to generate and mail notices, plus implementation, sets the latest date the rates must be final.

Planning checklist

• Confirm the rating law, review practice and any public process for each state and line.
• Set target effective dates for new business and renewals, then work backward through notice, implementation and review.
• Fix the experience period, evaluation date and projection assumptions.
• Schedule each internal review and approval, with time for rework.
• Decide capping and transition rules and confirm each state allows them.
• Identify related rule and form filings and align their dates.
• Pull each state's checklist and required exhibits before building the filing.
• Sequence filings by lead time and dependencies; record them in one tracker.
• Assign owners and response targets for objections.
• Plan system changes and testing against approved, not proposed, rate pages.
• Draft and approve policyholder notices for each state's requirements.
• After implementation, reconcile premium impact with the filed figures.
