File-and-use rating laws are insurance regulations allowing an insurance company to use new rates prior to receiving state approval. File-and-use rating laws allow the insurer to immediately use the new rates, with the insurance regulator having the option to strike down any rate change if it determines that the change cannot be justified.
Insurance is regulated on a state level, and states use different mechanisms to regulate the rates that insurance companies are allowed to charge consumers. Regulators balance an insurer’s need to remain solvent by offering policies that bring in enough premiums relative to promised benefits while ensuring that consumers are offered fairly priced policies. This means that state insurance regulators monitor and approve rates.
States have adopted different procedures for approving changes to insurance rates. In a prior approval regulatory framework, insurance companies must first obtain approval for any rate change, with approval requiring the insurer to justify why a rate change is necessary. Flex-rating laws allow an insurer to immediately adjust its rates unless the percentage change is above a certain threshold. Any rate increase above the threshold will incur regulatory scrutiny to ensure that it is not unreasonable. Open competition laws allow insurance companies to change rates at their discretion, provided that the company gives regulators a copy of its ratings schedule when requested.
File-and-use ratings laws allow insurance regulators to let market forces determine rates, while still affording regulators the option of stepping in to ensure that the market is orderly and consumers are protected. The idea is that insurance companies will self-regulate when it comes to increasing rates, since charging more than competing insurance companies for a policy type will price the insurer out of the market. Most states use a file-and-use approach rather than requiring insurers to obtain prior approval for rate changes.
