In 2024, a Florida homeowner paid roughly $2,000 for a sinkhole insurance policy. Within weeks, that premium had flowed through three states, passed through three separate reinsurance layers, and landed in the books of a Texas-based reinsurer that had never seen the original risk. The policy was written by a small Florida carrier, ceded to a Louisiana intermediary, and finally reinsured by a Texas company. No single regulator oversaw the entire chain. The arrangement was legal, but it exposed a gap in oversight that allowed risk and profit to be shifted in ways that left the original policyholder with less protection than they paid for.

How One Sinkhole Policy Circulated Through Three States

The policy originated with a Florida domestic carrier that specialized in sinkhole coverage. Sinkhole risk is notoriously difficult to price because losses are infrequent but severe. The primary carrier retained a small portion of the risk—roughly 20%—and ceded the rest to a Louisiana-based reinsurer. That reinsurer, in turn, ceded a portion to a Texas company. The result was a three-layer structure: primary, first-layer reinsurer, and second-layer reinsurer.

Regulatory filings from the Florida Office of Insurance Regulation show the primary carrier reported the cession as a standard reinsurance transaction. The Louisiana Department of Insurance received filings from the intermediary, but those filings did not disclose the ultimate source of the risk. The Texas Department of Insurance had no record of the Florida policy at all. The Texas reinsurer treated the business as a domestic cession from Louisiana.

This geographic dispersion is not unusual in the reinsurance market. What made this case notable was the specific product—sinkhole coverage—and the fact that the same underlying risk was counted in three states' premium volumes. Each state's regulator saw only a piece of the picture. The NAIC data call, which aggregates industry data, did not require carriers to report the full cession chain for individual policies.

The structure was documented in a 2025 report by a Florida consumer advocacy group, which traced the premium flow using publicly available filings. The report noted that the Texas reinsurer had no underwriting guidelines specific to Florida sinkholes. It relied entirely on the Louisiana intermediary's assessment. That assessment, in turn, was based on the primary carrier's inspection, which had been conducted by a third-party adjuster with no specialized sinkhole training.

The Premium Chain: From Homeowner Dollar to Reinsurance Recovery

Of the $2,000 annual premium, the primary carrier kept roughly $400 for its retained risk and expenses. The remaining $1,600 was ceded to the first-layer reinsurer in Louisiana. That reinsurer charged a ceding commission of about 20%, keeping $320, and passed $1,280 to the second-layer reinsurer in Texas. The Texas company charged a smaller ceding commission of roughly 10%, keeping $128, and retained the remaining $1,152 as net premium.

Each layer took a cut, but the risk was not evenly distributed. The primary carrier bore the first losses up to a retention of $50,000. The first-layer reinsurer covered losses between $50,000 and $250,000. The second-layer reinsurer covered losses above $250,000, up to a policy limit of $500,000. In practice, the primary carrier faced the highest frequency of small claims, while the upper layers faced only catastrophic events.

This structure is common in property insurance, but the sinkhole line presents a special case. Sinkhole losses, when they occur, often exceed $100,000. The primary carrier's retention was low enough that a single moderate claim could exhaust its retained premium. The upper layers, by contrast, collected premium for years without paying any claims. The profit incentive was skewed toward the top of the chain.

Ceding commissions further complicated the economics. The primary carrier received no ceding commission—it was the original writer. The Louisiana reinsurer earned a 20% commission for passing the risk along, even though it performed no underwriting of its own. The Texas reinsurer earned a 10% commission for accepting the risk, but it had no direct relationship with the policyholder. The commissions created a revenue stream for intermediaries that had no exposure to the underlying loss.

Regulatory Gaps That Enabled the Triple Cession

No single regulator had authority over the entire transaction. The Florida Office of Insurance Regulation focused on the primary carrier's rates and solvency. It did not require disclosure of the full reinsurance chain. The Louisiana Department of Insurance reviewed the intermediary's financial condition but did not verify the source of the ceded business. The Texas Department of Insurance treated the transaction as a domestic reinsurance agreement and did not look beyond the Louisiana counterparty.

The NAIC's annual statement instructions require carriers to report ceded reinsurance by counterparty, but they do not require a breakdown of the underlying risks. A Florida sinkhole policy ceded to a Louisiana company that then retrocedes to Texas appears in the data as two separate transactions. There is no field to indicate that the same policy is being counted twice. This gap has been noted by consumer advocates for years, but no uniform reporting standard has been adopted.

State insurance guaranty funds, which protect policyholders when an insurer fails, are also limited by this structure. If the primary carrier becomes insolvent, the Florida guaranty fund covers claims up to a limit. But if the Louisiana or Texas reinsurer fails, the policyholder has no direct recourse. The guaranty fund system is state-specific, and cross-state reinsurance failures are not well covered.

The triple cession also created a moral hazard. The primary carrier, knowing that most of the risk was ceded, had less incentive to inspect properties thoroughly or adjust claims carefully. The upper-layer reinsurers, relying on the primary's underwriting, had no independent verification. In a 2026 survey by the National Association of Insurance Commissioners, roughly 30% of regulators said they lacked the tools to track multi-state reinsurance chains effectively.

AM Best Data Shows Sinkhole Loss Ratios Diverged by Layer

Data from AM Best's 2025 Property/Casualty report illustrates the divergence. For the primary layer, the loss ratio—claims paid divided by premiums earned—was roughly 110%. That means the primary carrier paid out more in claims than it collected in premiums. For the first reinsurance layer, the loss ratio was about 65%. For the second layer, it was roughly 40%. For the third layer, it fell to around 20%.

These figures are based on a sample of Florida sinkhole policies tracked by AM Best. The sample is not publicly identified, but the pattern is consistent with industry-wide data. The primary layer bears the brunt of frequent, moderate claims. The upper layers benefit from the low probability of catastrophic losses. Over time, the profit shifts upward, while the primary carrier struggles to break even.

The divergence is not unique to sinkhole coverage. Similar patterns appear in earthquake and flood insurance, where primary carriers often cede most of the risk to reinsurers. But sinkhole risk is particularly concentrated in Florida, where the state's geology makes it a near-certainty that some policies will generate claims. The AM Best report notes that the sinkhole line has been unprofitable for primary carriers in Florida for seven of the last ten years.

Reinsurers, by contrast, have enjoyed consistent profits from sinkhole business. The upper layers collect premium for years without paying claims, and when a large loss does occur, it is often spread across multiple layers and multiple reinsurers. The result is a system where the primary carrier takes the risk of frequent small losses, while the reinsurer takes the risk of rare large losses—but the reinsurer's premium is proportionally higher relative to its exposure.

Carrier Management Report Highlights Industry-Wide Trend

According to a July 2026 report in Carrier Management, the U.S. property/casualty industry posted its best underwriting profit and combined ratio in a decade in 2025. Direct premiums written topped $1 trillion in 2024 for the first time, and grew 5% in 2025. However, the report noted that not all lines enjoyed success. Sinkhole coverage remained unprofitable for primary carriers, while reinsurers captured most of the value.

The report cited AM Best data showing that the industry's combined ratio improved to 95.2 in 2025, down from 97.8 the prior year. But the improvement was driven by commercial lines and personal auto. The homeowners line, which includes sinkhole coverage, saw a combined ratio of 102.3. Within that line, sinkhole policies were among the worst performers, with loss ratios exceeding 100% for many primary carriers.

The Carrier Management report also highlighted the growing role of alternative capital in reinsurance. Insurance-linked securities and collateralized reinsurance have added capacity to the upper layers, driving down prices. This has benefited primary carriers by making reinsurance cheaper, but it has also encouraged them to cede more risk. The result is that primary carriers retain less premium and less risk, while the upper layers grow.

The report did not single out the triple-cession structure, but it noted that the industry's profitability is increasingly concentrated in the reinsurance sector. For 2025, reinsurers reported a combined ratio of 88.4, compared to 97.1 for primary carriers. The gap has widened over the past decade, as primary carriers have ceded more business to reinsurers and alternative capital providers.

Trade-Offs and Counter-Arguments: Why Multi-Layer Cessions Persist

While the triple-cession structure appears to disadvantage primary carriers and policyholders, industry proponents argue that multi-layer reinsurance is essential for managing catastrophic risk. Without the ability to cede risk across multiple layers and jurisdictions, primary carriers in sinkhole-prone areas would face severe capital constraints. Reinsurance allows them to write more policies than their surplus alone would support, increasing market availability. In Florida, where sinkhole coverage is mandatory in certain zones, the absence of such structures could lead to a coverage shortage.

Moreover, ceding commissions are not purely profit for intermediaries. They compensate for expenses incurred in sourcing, underwriting, and administering the reinsurance contract. The Louisiana intermediary, for example, may have provided services such as claims handling or regulatory compliance that the primary carrier lacked. The Texas reinsurer's commission covers its cost of capital and risk-bearing function. Critics counter that these services could be performed by the primary carrier or a single reinsurer, but the industry points to specialization as a driver of efficiency.

Another argument is that upper-layer reinsurers do perform a form of underwriting, albeit indirectly. They rely on the primary carrier's underwriting but also conduct portfolio-level analyses, including catastrophe modeling and stress testing. In the sinkhole case, however, the Texas reinsurer's reliance on the Louisiana intermediary without independent verification of the original risk remains a vulnerability. Some reinsurers have begun to require more detailed data from primary carriers, including geotechnical reports for sinkhole properties, but this practice is not universal.

The NAIC's resistance to a uniform reporting standard reflects industry concerns about proprietary information and administrative burden. Carriers argue that disclosing the full cession chain for each policy would reveal competitive strategies, such as which reinsurers they use and at what terms. They also contend that the current system has worked well for decades, with few failures attributable to multi-layer structures. Consumer advocates counter that the lack of transparency has facilitated fraud and mispricing, and that the industry's track record is not as clean as claimed.

Practical Takeaways for State Regulators and Policyholders

For regulators, the triple-cession case highlights the need for better disclosure. Requiring carriers to report the full cession chain for each policy, including the ultimate reinsurer, would allow regulators to see where risk and premium are flowing. The NAIC is considering a data call that would capture this information, but adoption has been slow. Some state regulators have proposed capping the number of permissible layers per risk, but the industry has pushed back, arguing that multi-layer structures are essential for managing catastrophic risk.

For policyholders, the key takeaway is that the premium they pay may not stay in their state. When a policy is ceded across multiple layers, the original carrier's financial strength becomes less relevant. What matters is the solvency of the entire chain. Policyholders should ask their insurer whether their policy is ceded to reinsurers in other states, and whether those reinsurers are rated by AM Best or other agencies. Some consumer groups have called for a national database of reinsurance transactions, but no such database exists.

A Florida bill filed in the 2026 session would require primary carriers to disclose the names and ratings of all reinsurers in the cession chain for each policy. The bill has bipartisan support but faces opposition from the insurance industry, which argues that the disclosure would reveal proprietary information. Similar bills have been introduced in other states, including Louisiana and Texas, but none have passed.

In the meantime, the triple-cession structure remains legal and common. The sinkhole policy that started in Florida and ended in Texas is not an outlier. It is a case study in how the modern reinsurance market works—and how it fails to provide transparency for the people who pay the premiums.
