Rate On Line Definition

What Is Rate on Line?

Rate on line (ROL) is the ratio of premium paid to loss recoverable in a reinsurance contract. Simply put, ROL represents how much money an insurer must commit in order to obtain reinsurance coverage. A high ROL signals that the insurer must pay more for coverage, while a lower ROL means an insurer must pay less for that same level of coverage.

Key Takeaways

  • Rate on line (ROL) is the ratio of premium paid to loss recoverable in reinsurance contracts, which signals how much money an insurer must pay to obtain reinsurance coverage.
  • A high ROL indicates that the insurer must pay more for coverage, while a low ROL means an insurer pays less for that same coverage.
  • The ROL metric helps reinsures determine if it makes fiscal senses to enter into a given contract with an insurer.
  • To fairly price a ROL contract, reinsurers consider various points of data, including an insurer’s exposure, as well as historical losses experienced by the broader industry.

Understanding Rate on Line

Reinsurance lets insurance companies increase their capacity to underwrite new policies by transferring some of their liabilities to reinsurers. In exchange for doing this, the reinsurers receive a portion of the premiums insurers collect on those additional policies.

To price a reinsurance contract, a reinsurer must consider several factors, including the insurer’s exposures, as well as recent losses experienced by the industry at large. To accomplish this, reinsurers study market benchmarksincluding the frequency and severity of claims made. If the number of reinsurers is limited and if recent historical losses have been substantial, insurers should expect to pay more for reinsurance coverage.

In such cases, insurers may adjust their underwriting activities by charging higher premiums or by altering the way they invest in premiums in order to maintain excess capacity.

The rate on line (ROL) is the inverse of the payback or amortization period.

Consider a property insurance company that seeks to shift some of its risk to a reinsurance company, in a concerted effort to mitigate its exposure to losses from potentially catastrophic flood activity. In this hypothetical scenario, both the reinsurer and insurer examine the severity and frequency of past claims and collectively decide on a contract in which the reinsurer will assume up to $20 million in liabilities.

In exchange, the insurer agrees to pay the reinsurer $4 million in premiums. Consequently, the rate on line for this contract is calculated by dividing the premium by the coverage, which comes to 20%. The payback period would be five years.

Rate on Line in Projecting Reinsurance Profitability

Rate on line helps reinsurers gauge the potential profitability of a proposed contract. But this analysis becomes complicated when reinstatement provisions, expenses, and carry-forward provisions from earlier years are taken into account.

Calculations become even more difficult when additional premium and profit commission percents change for each year or if coverage is canceled. Fortunately, using a frequency distribution can help insurers and reinsurers visualize this data because the mean of the distribution relates to the payback period for traditional risk covers. This payback period can be compared to the results of catastrophe models or other pricing analyses.
