Reinsurance

Reinsurance refers to the practice of an insurance company transferring a portion of the risk it assumes in exchange for a premium payment to another insurance company, known as a reinsurer. In other words, reinsurance is a way for insurance companies to mitigate their risk by sharing it with another company.  

Here are some key features of reinsurance:

  • The reinsurer assumes a portion of the risk of the primary insurer in exchange for a premium payment.

  • Reinsurance can be used to protect the primary insurer from catastrophic losses or to allow it to underwrite more policies without taking on too much risk.

  • The primary insurer remains responsible for the policyholder and pays any claims that arise, but may receive reimbursement from the reinsurer for a portion of the claims paid.

  • There are different types of reinsurance agreements, including proportional and non-proportional reinsurance.

  • Reinsurance is often used in the property and casualty insurance industry, but can also be used in other types of insurance such as life and health insurance.

For example, an insurance company that sells policies in a region that is prone to hurricanes may choose to purchase reinsurance to protect itself against large losses in the event of a major hurricane. The primary insurer may enter into a proportional reinsurance agreement with a reinsurer, where the reinsurer agrees to assume a portion of the risk for the policies sold in the region in exchange for a premium payment. If a hurricane strikes and causes significant damage, the primary insurer would pay the claims of its policyholders, but may be reimbursed by the reinsurer for a portion of the claims paid.

According to Mployer Insights’ 2026 analysis of 76,000+ employer benefit plans, disability insurance remains a major market differentiator, with only 41% of U.S. employers offering short-term disability (STD) and 38% offering long-term disability (LTD). While 60% salary replacement serves as the national standard across both benefit types, standard plan designs disproportionately expose higher earners due to median benefit caps of $1,602/week for STD and $8,273/month for LTD. Furthermore, alignment between STD benefit durations (median 26 weeks) and LTD elimination periods (68% at 90 days) remains a critical area for plan structure optimization.

According to Mployer Insights’ 2026 analysis of 50,000+ employer health plans, prescription drugs account for over 25% of total benefit expenses, with Tier 4 specialty drugs driving the majority of high-cost claims. While Tier 4 copays average $123 with coinsurance requirements in 31% of plans, individual oncology therapies like Darzalex Faspro ($170,800/yr) and Keytruda ($158,200/yr) frequently exceed average individual stop-loss deductibles ($141,938). To mitigate exposure, self-funded employers are increasingly turning to independent, transparent PBM models and biosimilar substitution—which yields up to a 73% net cost reduction per patient.
