What does it mean for Maryland to be a RATE file and use state?

In Maryland, being a RATE file and use state means that insurers have the ability to file their rates and can begin using them immediately, provided that there are no objections raised within a specific timeframe—30 days in this case. This system allows for quicker implementation of new rates, which can be beneficial for insurers in a changing market. Essentially, if no objections are submitted to the insurance department within the 30-day period, the filed rates become effective automatically.

The other options do not accurately reflect the meaning of a RATE file and use state. While options regarding the establishment of rates by a commissioner or a rating organization may be relevant to how rates can be adjusted or approved in different contexts, they do not capture the essence of the specific process that allows insurers in Maryland to use rates immediately after filing under the stipulation of a waiting period for objections.
