^{U.S. states employ a variety of rate regulation mechanisms, including prior approval, modified prior approval, file and use as well as use and file. Some states do not require explicit regulatory approval prior to insurers using new rates. This analysis is based on when rate filings are "disposed" by state regulators and does not take into account when those new rates became effective for new and renewal business. In some instances, a new rate may have been in effect prior to the month the filing was approved by the regulator.}

^{All figures listed are based on aggregations and weighted averages of as-reported numbers filed in the rate filings of each subsidiary in each state. The overall rate impact is calculated based on the aggregated written premium change from all rate filings during the period as a percentage of the largest written premium submitted by each filer in the group in every state. The overall rate impact for each group, in some states, may be higher or lower than each approved change in the period.}

^{The calculated premium change is not a final projection of the additional premium the insurer may receive in the upcoming year. The calculated premium change is reported by each insurer to reflect the most impactful premium changes based on the combined impact of the percentage change and the amount of business it affects. Changes to the insurer's policy mix or policies-in-force are not factored into the analysis.}
