INSURANCE BULLETIN 16-03 Request for Comment – Premium Stabilization Issued: February 2, 2016 The following Bulletin is issued by the Missouri Department of Insurance, Financial Institutions and Professional Registration (“Department”) to inform and educate the reader on the specified issue. It does not have the force and effect of law, is not an evaluation of any specific facts or circumstances, and is not binding on the Department or an insurer. See §374.015, RSMo.

To: All insurers writing property and casualty insurance in the State of Missouri, producers and any other interested stakeholders From: John M. Huff, Director Re: Request for Comment – Premium Stabilization
3
The Department is considering promulgating rules regarding the use of premium stabilization rules or practices by property and casualty insurers. Premium stabilization is generally understood to be a practice intended to moderate a significant premium change on a segment or block of business. Premium stabilization is a temporary or limited duration practice and does not replace traditional underwriting and rating methodologies, which are based on actuarial standards and practices.
4
Premium stabilization is generally used in two circumstances. The first circumstance is when significant changes to the insurer’s base rates may result in large premium changes (increases or decreases) to policyholders. An insurer will utilize premium stabilization to phase in an indicated or needed rate change to avoid policyholder rate volatility. The second circumstance is when an insurer significantly modifies its rating systems or when an insurer merges or acquires business from a different insurer (either within the same group of affiliated companies or outside of the group). In this instance, the company may utilize what are referred to as “transitional rules” to effectively accomplish the same moderation of premium changes. 1

Previously, the Department had issued Bulletin 11-02, “Personal lines premium stabilization of renewal policies”. Bulletin 11-02 expired on December 31, 2012 and was formally rescinded on January 12, 2015.

The Department is considering the regulatory issues and concerns related to premium stabilization practices. The Department is issuing this Bulletin specifically to solicit public comment, gather additional information and determine how best to proceed.

Interested parties are asked to submit comments regarding the use of premium stabilization practices in the State of Missouri no later than March 17, 2016. Comments should be submitted to: marketregulation@insurance.mo.gov .

The Department is specifically seeking comment on the following key issues:
9
 The definition of premium stabilization practices;  The extent to which premium stabilization practices comply with Missouri rating laws that generally provide that rates shall not be “excessive, inadequate or unfairly discriminatory”;  The circumstances under which premium stabilization practices are appropriate and permissible, if any;  The circumstances under which premium stabilization practices are not appropriate, if any;  Those lines of insurance to which premium stabilization practices should be permitted;  The appropriate duration of premium stabilization practices (e.g., by renewal cycle);  Any limitations on the practice of premium stabilization (e.g., percentage limitations);  The extent to which different consideration should be given to the two types of premium stabilization practices described herein – large internal rate changes versus the acquisition of new blocks of business;  The extent to which it should be permissible for insurers to modify premiums for a policyholder, i.e., to minimize the rate change a policyholder experiences they are switched from one insurer to another through a merger, acquisition or inter-affiliate transfer;  Whether multiple premium stabilization practices should be permitted to be applied (simultaneously or subsequently) within the same book of business;
