Extended reporting period wording and examples

Coverage description

An extended reporting period allows certain claims to be reported after a claims-made policy ends, subject to the policy’s terms, dates, and covered acts. The reporting window and the acts eligible for coverage depend on each endorsement.

How an extended reporting period works

A claims-made policy covers claims first made during the policy period, so a claim made after the policy ends is covered only through an extended reporting period. In CG 00 02, the claims-made Commercial General Liability Coverage Form, a basic extended reporting period applies automatically and without charge when the coverage is canceled or not renewed, or is replaced by insurance with a later retroactive date or not written on a claims-made basis. It lasts five years for claims from occurrences or offenses reported within 60 days after the policy ends, and sixty days for those not reported. A supplemental extended reporting period of unlimited duration is available only by endorsement, CG 27 10, for an extra charge requested within 60 days, and it provides separate aggregate limits equal to the expiring ones. Neither period extends the policy period or the scope of coverage, so the injury or offense must still fall after the retroactive date and before the policy ends.

Notable clauses

“reported to Us in writing, during the sixty (60) days immediately following the Policy Termination Date”

The Hanover Insurance Company · Accountants Advantage Professional Liability Insurance Policy Form · 915-1001 01/20

Automatic 60 days. The free extension covers only claims made during the policy period, so a claim first made after the policy ends needs the optional period.

“in place of, not in addition to, the automatic Extended Reporting Period”

The Hanover Insurance Company · Accountants Advantage Professional Liability Insurance Policy Form · 915-1001 01/20

Optional period replaces the automatic one. Buying the optional period substitutes it for the 60-day window rather than adding the two together.

“within thirty (30) days following the effective date of termination or nonrenewal”

Everest National Insurance Company · (Illinois) Extended Reporting Period · PCI-ILF051A-1 0626

Election deadline. The right to the extension lapses unless written notice and the additional premium reach the insurer within 30 days.

“a period of one (1) year following the Supplemental Extended Reporting Period Effective Date”

Society Insurance, a mutual company · Supplemental Extended Reporting Period Endorsement · SIBP 15 01 08 26

One-year window. Claims first made during that year can be reported, but only for wrongful acts on or before the effective date.

“You must give us a written request for the endorsement within 60 days after the end of the policy period”

The First Liberty Insurance Corporation · Commercial General Liability Coverage Form (claims-made) · CG 00 02 12 25

Supplemental period request. The basic period applies without a request; the unlimited supplemental period exists only if the insured asks in time and pays the additional premium.
