The CU 27 - Claims Made Endorsements are as follows:
CU 27 00-Underlying Claims-Made Coverage
The Insurance Services Office (ISO) CU 00 01-Commercial Liability Umbrella Coverage Form is written on an occurrence basis. This works well because all auto coverage and most general liability coverage is written on an occurrence basis.
These endorsements address the changes that must be made when underlying coverages are written on a claims made basis.

CU 27 02-Amendment-Extended Reporting Periods for Specific Accidents, Products, Work, or Location
