Understanding Difference in Conditions (DIC) Insurance
In the world of commercial property insurance, standard policies often leave significant gaps in coverage, particularly concerning catastrophic perils. This is where the Difference in Conditions (DIC) policy serves a critical role. A DIC policy is a specialized form of insurance designed to provide coverage for perils that are excluded from standard property policies, effectively acting as a "gap-filler" or a wrapper around the primary program.
For candidates preparing for the complete E&S Lines exam guide, understanding DIC is essential because these policies are almost exclusively written in the non-admitted or surplus lines market. Admitted carriers typically shy away from the high-severity, low-frequency risks associated with DIC policies, such as massive earthquakes or widespread flooding.
Standard Property vs. DIC Policies
| Feature | Standard Commercial Property | Difference in Conditions (DIC) |
|---|---|---|
| Primary Purpose | Covers Fire, Lightning, Wind, Theft | Fills gaps and covers catastrophic perils |
| Common Perils | Named Perils or Open Perils (with exclusions) | Earthquake, Flood, Landslide, Mudflow |
| Coinsurance | Usually required (80%, 90%, 100%) | Typically no coinsurance requirement |
| Market Location | Admitted (Standard) Market | Non-Admitted (Surplus Lines) Market |
The Role of DIC in the Surplus Lines Market
DIC policies are a staple of the surplus lines industry for several reasons. First, the flexibility of rate and form allows surplus lines insurers to tailor coverage to a specific property's unique geographic risks. For instance, a building located on a fault line requires a different premium and deductible structure than a building in a flood zone.
Key characteristics of DIC policies in the E&S market include:
- No Coinsurance: Unlike standard property forms, DIC policies usually do not penalize the insured for under-insuring to the full value of the property. This is because DIC is often used to provide a specific limit for a specific peril (e.g., $5 million in earthquake coverage for a $20 million building).
- High Deductibles: DIC deductibles are often stated as a percentage of the total insured value (TIV) or a high flat dollar amount to ensure the insured retains a portion of the risk.
- Peril-Specific Limits: A DIC policy might provide sub-limits that are much lower than the primary policy's total limit, focusing only on the catastrophic exposure.
Common DIC Coverage Triggers
Interaction with Primary Policies
A DIC policy is designed to work in tandem with, not in place of, the primary property policy. It is often referred to as a "complementary" coverage. If a loss occurs, the adjuster first looks at the primary policy. If the peril (such as fire) is covered by the primary policy, the DIC policy does not respond. However, if the peril (such as an earthquake) is excluded by the primary policy, the DIC policy drops down to provide coverage, subject to its own deductible.
It is important for brokers to ensure there is no overlap that could lead to disputes. To master these nuances, students should review practice E&S Lines questions regarding concurrent causation and policy language.
Exam Tip: The Diligent Search Requirement
On the Surplus Lines Exam, remember that even though DIC policies are common in the E&S market, the diligent search requirement still applies in most states. A broker must typically prove that the coverage (e.g., the specific flood or earthquake limit) was unavailable from admitted carriers before placing the DIC policy through a surplus lines insurer.
Underwriting Considerations for DIC
Underwriters in the surplus lines market evaluate DIC risks differently than standard property risks. They focus heavily on probabilistic modeling. For earthquake coverage, they look at soil types, distance to fault lines, and building construction (e.g., reinforced masonry vs. wood frame). For flood coverage, they analyze base flood elevations and historical surge data.
Because these risks are catastrophic, the surplus lines insurer must carefully manage its aggregate exposure. This means they limit the total amount of insurance they write in a specific geographic zone (like a single zip code) to avoid insolvency in the event of a single massive disaster.
