Canonical Insurance Definitions (16)

Standard ISO Sourced

Actual Cash Value ACV

Physical Damage • ISO Form PP 00 01 Part D

The fair market value of a vehicle immediately prior to an accident or loss, calculated as replacement cost minus depreciation, age, mileage, and physical wear-and-tear.

Real-World Scenario:

If a car purchased for $30,000 is totaled after 4 years when its fair market resale value is $18,000, the insurer pays $18,000 minus the collision deductible.

Underwriting & Billing

Comprehensive Loss Underwriting Exchange. A national database maintained by LexisNexis containing up to 7 years of auto insurance loss claims, payouts, and inquiries associated with an individual driver or vehicle VIN.

Real-World Scenario:

Insurance underwriters pull your C.L.U.E. report when pricing a new auto quote to verify prior at-fault accidents and comprehensive claims.

Collision Coverage

Physical Damage • ISO Form PP 00 01 Part D

First-party insurance that pays to repair or replace your vehicle if it collides with another motor vehicle, hits a stationary object (tree, guardrail, pole), or is involved in a single-vehicle rollover.

First-party insurance that covers physical damage to your vehicle resulting from non-collision perils, including theft, vandalism, hail, fire, flood, falling objects, windshield cracks, and animal strikes.

Real-World Scenario:

Declarations Page Dec Page

Underwriting & Billing

The legally binding summary schedule at the beginning of an auto insurance policy specifying policy numbers, effective dates, covered drivers, insured vehicle VINs, specific coverage limits, deductibles, and itemized premium charges.

Real-World Scenario:

Before switching carriers, audit your existing declaration page line-by-line against competing quotes to confirm limit and deductible parity.

Diminution of Value DV

Liability

The permanent loss in a vehicle market resale value that occurs after it sustains accident damage, even if structural and cosmetic repairs are restored to pristine condition.

Real-World Scenario:

A luxury sedan worth $45,000 before a crash may only be worth $38,000 on CARFAX after repairs; a third-party DV claim seeks recovery of the $7,000 difference.

Guaranteed Asset Protection GAP

Policy Endorsement

An optional endorsement that pays the financial shortfall between your vehicle Actual Cash Value (ACV) payout and the remaining balance owed on your auto loan or lease if the car is totaled or stolen.

Real-World Scenario:

If you owe $24,000 on your loan but the insurer values your totaled vehicle at $19,000, GAP coverage pays the $5,000 deficiency to the lienholder.
