Glossary

Design liability is liability arising out of errors or omissions in the practice of providing professional design services. Although design services encompass a broad range of activities, including product design, in insurance circles this term is most often used to describe liability arising out of the providing of architectural, engineering, and surveying services.

Destroyed medical waste is regulated medical waste that has been ruined, torn apart, or mutilated through thermal treatment, melting, shredding, grinding, tearing, or breaking so that it is no longer generally recognized as medical waste but has not yet been treated (excludes compacted regulated medical waste).

Destruction and removal efficiency (DRE) is a percentage that represents the number of molecules of a compound removed or destroyed in an incinerator relative to the number of molecules that entered the system. For example, a DRE of 99.99 percent means that 9,999 molecules are destroyed for every 10,000 that enter. The percentage 99.99 is known as "four nines." For some pollutants, the Resource Conservation and Recovery Act (RCRA) removal requirement may be as stringent as "six nines."

The development factor is a factor applied to losses before they are fully matured to account for loss development and incurred but not reported (IBNR) claims. Factors are derived from historical data to reflect actual trends in loss development.

A deviation in an insurance context concerns a rate or policy form differing from that published by a rating bureau.

Difference-in-conditions (DIC) insurance is a policy that provides additional limits of coverage for specific perils when standard markets won't provide adequate limits, adds coverage for perils that are excluded on standard coverage forms, or supplements international policies written by admitted insurers in the applicable foreign countries. It is an all risks property insurance policy that is purchased in addition to a commercial property policy to obtain coverage for perils not insured against in the commercial property policy (usually flood and earthquake). It is also an endorsement to a contractor's blanket builders risk insurance policy that fills the gaps between a policy provided by the project owner and the contractor's policy so that the contractor has insurance comparable to what it would have had if coverage had been arranged under the contractor's builders risk program. When a project owner elects to provide the builders risk coverage for all parties with an insurable interest, the project is normally removed from coverage under the contractor's policy. A DIC endorsement typically states that, to the extent a loss is not covered under the owner-provided policy but would be covered under the contractor's policy, coverage will apply on an excess basis. It is also an insurance policy that is designed to fill the gaps between the coverage provided by a multinational organization's master insurance policies (property or liability) and coverage provided by policies purchased locally in accordance with each country's insurance requirements so that the organization has uniformity of coverage regardless of location. This policy is referred to as a foreign DIC policy.

A difference-in-limits (DIL) clause is a provision contained in an insurance policy that provides coverage for the difference in limits between the limits of that policy and another policy that also covers the insured for the perils insured against.

A difference-in-limits (DIL) policy is a type of difference-in-conditions (DIC) insurance policy or clause within a DIC policy that may reimburse additional expenses greater than the limit established in the standard insurance policy.

Digital assets are created, stored, or represented items that have value. These assets can be owned, managed, transferred, or used under defined rights or permissions. Documents, images, videos, audio files, cryptocurrencies, tokens, and other digital records are examples of digital assets.

A digital flood insurance rate map (DFIRM) is a flood insurance map developed by the Federal Emergency Management Agency (FEMA) for use with Geographic Information Systems (GIS) technology.
