ISO TIME ELEMENT
COVERAGE FORMS AVAILABLE ENDORSEMENTS AND THEIR USES
(December 2025)
This article identifies
endorsements available to modify the Insurance Services Office (ISO) Time
Element Coverage Forms. It is organized by form number and title and provides a
brief explanation of each form's purpose. This section does not include any
state-specific information endorsements.
NOTE: Endorsements added and/or changed with and after the 10 12 edition are in bold
type.
The ten-digit sequence
used in ISO forms and endorsements has a very specific meaning.
Endorsements are categorized based on their
purpose as follows:
The declarations page
summarizes essential details for this coverage part, Commercial Property. It
includes the insured's name, a description of the premises, coverage limits,
mortgage information (if applicable), deductibles, and a list of the relevant coverage
forms.
Related Article: CP DS
00–Commercial Property Coverage Part Declarations
CP DS 00 permits the
entry of only a single premise. If there are multiple premises, an advisory
supplemental declaration must be provided detailing each premise, the
applicable coverages, mortgage holders, and endorsements.
This endorsement renews
the policy exactly as it is, aside from any noted changes. All forms and
endorsements that differ from those on the expiring policy must be attached.
This schedule must
always be included whenever CP 13 20–Additional Locations – Special Coinsurance
Provisions is attached to the policy. Its primary purpose is to list additional
locations acquired or reported after the policy starts, monitor property values
for a value reporting policy, and specify insurance limits for each reported,
acquired, or incidental location.
This schedule outlines
the property description for which the insured is legally responsible. It may
include the insured’s location, occupancy, the covered property, and insurance
limits. Additionally, it is advisable to include this schedule with CP DS 00.
(02 19 edition)
This schedule details
the premises or locations covered for earthquakes and volcanic eruptions. It
includes sections to specify coverage as either blanket or separate limits for
each location. Additionally, there are spaces to indicate the masonry veneer
option, whether sprinkler leakage applies, and whether an increased annual
aggregate limit option is desired.
When leasehold coverage
is selected, this schedule provides the Tenants' Lease Interest, Bonus
Payments, Improvements and Betterments, Prepaid Rent options, and the total
coverage for the insured's leasehold interest.
This schedule details
the premises or locations covered by flood insurance, the deductible if no
coinsurance applies, and other flood insurance. It also includes sections to
indicate whether coverage is blanket or separate limits for each location.

Element Coverage Forms Analysis
This form is similar to
the CP 00 30 except it does not provide Extra Expense Coverage. It details coverage
available to businesses against financial losses resulting from temporary
shutdowns or slowdowns caused by direct physical damage or loss covered by the
policy. Similar to CP 00 30, the form summarizes the insured’s information,
specific premises covered, policy limits, and the causes of loss.

This form provides
details about the coverage available exclusively for Extra Expense Coverage,
including the coverage limit, restoration period, and any applicable
coinsurance percentage. It is attached to the commercial package policy.

coverage for the lease information, the tenant’s lease interest, and the
coverage limits.

This form outlines the
conditions of the commercial property insurance policy. It details the
responsibilities and obligations of both the insured and the insurance company.

misrepresentation, provisions related to other insurance, and property control,
among others.

CP 00 90–Commercial Property Conditions Form Analysis
This endorsement is
mandatory in several states and excludes loss or damage caused by viruses or
other microorganisms. While most states use this version of the endorsement,
some may have different form numbers but with the same title. Regardless of the
version, the primary purpose remains essentially the same.
(10
12 changes)
This endorsement allows
the insured to plan for replacing existing non-green construction with green
construction in the event of a loss. A specific percentage of the insurance
limit must be listed on the endorsement schedule, along with the maximum payout
available for these upgrades. Additionally, the coverage period for restoring
business income can be extended to account for the extra time needed for these
improvements.
The 10 12 edition's
changes align with CP 00 10 updates, offering more scheduling flexibility on
the endorsement and addressing deductible issues.
(10
12 edition)
This endorsement allows for increases in Coverage
Extensions, Additional Coverage, and Theft Limitations as detailed in the
coverage form. Any new limit entered will overwrite the existing limit in the
coverage form rather than adding to it. This option is only available if the
coverage form specifically allows the limit to be increased.
This coverage form is required
for policies covering public utility services, including electricity and power
utilities. It modifies the exclusion in the causes of loss form by expanding
the exception for resulting fire to include fire, explosions, and electrical
incidents affecting covered property and electrical equipment. Additionally,
this endorsement establishes a minimum deductible of $1,000.
(09
17 edition)
This endorsement
applies exclusively to fire related losses and supersedes IL 04 15. It is typically
added to the policy when the insurer offers premium credit for any of the listed
protective safeguards. It outlines the scheduled services or protective
safeguards at the insured's location and mandates the insured keep them
operational, ensuring they remain in the "on" position.
The schedule indicates
the premises and building numbers, along with the relevant symbols. These
symbols denote the protective safeguards and are specifically detailed in the
endorsement, such as automatic sprinkler systems, fire alarms, security services,
and service contracts with private fire departments.
NOTE: This is a warranty. If a fire loss
occurs and the described systems are not in proper working order at the time of
the loss, the insurance company will not pay for the loss.
(12
16 edition)
Unmanned aircraft operating off premises are not covered as
property unless this endorsement is attached. The aircraft must be listed with
a specific insurance limit. Valuation can be on an Actual Cash Value (ACV) or
Replacement Cost Value (RCV) basis.
Coverage may be blanketed. Business Income And Extra
Expense Coverages can be added, but only with the CP 10 30–Causes of
Loss-Special Form. A key restriction is that coverage does not apply when the
aircraft is used to deliver goods to others.
This endorsement
provides coverage for loss or damage to a business’s electronic data due to internet-related
transactions. It broadens the definition of employee for the purposes of this
endorsement to include temporary and leased workers.
Related Article: CP 04
30–Electronic Commerce (E-Commerce)
This endorsement
replaces the $15,000 limit for Additional Coverage–Limited Coverage for Fungus,
Wet Rot, Dry Rot and Bacteria in any of the causes of loss forms with the limit
on the endorsement schedule. The limit can apply per location if selected.
This form offers
named-peril coverage for a specific set of risks. These include fire,
lightning, explosion, windstorm or hail, smoke, aircraft or vehicle collisions,
riot or civil commotion, vandalism, sprinkler leaks, sinkhole collapse, and
volcanic action.
Related Article: Basic, Broad,
and Special Causes of Loss Forms Analysis
This form includes all
the perils listed in the Basic Form, plus additional perils: falling objects,
snow, ice, sleet buildup, and water damage from accidental discharge or leakage
of water or steam. Like the basic form, coverage only applies to the perils
specifically listed; any other perils are not covered.
Related Article: Basic, Broad,
and Special Causes of Loss Forms Analysis
(09 17 edition)
This policy provides
coverage for direct physical loss or damage to property unless a specific cause
is explicitly excluded or limited in the policy. Common exclusions include wear
and tear, inherent vice, mechanical breakdown, and certain types of water
damage, among others.
Related Article: Basic, Broad,
and Special Causes of Loss Forms Analysis
This form provides
coverage for physical damage and business income loss to covered property
resulting from earthquakes and volcanic eruptions. When these events are
included in coverage and a claim is made, this policy applies a flat-dollar
deductible rather than the more typical percentage deductible.
Related Article: Earthquake
and Volcanic Eruption Coverage
(02
19 edition)
This form is similar to
the CP 10 28, adding perils for Earthquake and Volcanic Eruption coverage, and
still using the fixed flat-dollar deductible. However, these coverages are
provided as a sub-limit.
Related Article: Earthquake
and Volcanic Eruption Coverage
This endorsement is withdrawn because its language was incorporated into
the 10 12 Causes of Loss Forms.
(10 12 edition) (Use with CP 10 30)
This endorsement
restricts coverage but allows the named insured to access the Causes of
Loss–Special Form benefits without incurring theft coverage costs. It can be
used as an underwriting tool, a cost-saving measure, or to prevent coverage
overlap, since an inland marine form also provides theft protection.
All theft losses are
excluded except those related to looting during a riot. The coverage also
includes losses or damages caused by burglars attempting to break in or out. The
2012 edition introduces a schedule to this endorsement.
(10
12 edition)
A tenant’s operations
might regularly produce vapor, gas, smoke, or other substances. This
endorsement excludes property damage caused by the tenant’s business
operations. It should be attached to both the tenant’s and the landlord’s
policies to prevent either party from being liable for foreseeable damages.
Examples include the
presence of grease residue over time and other legal or illegal substances.
(Use with CP 10 30)
This endorsement excludes
loss or damage to retaining walls, bulkheads, pilings, piers, wharves, and
docks if they are hit by a watercraft. Coverage is only required if such
waterfront property is included in the policy. Refer to CP 14 10–Additional
Property.
(10
12 edition)
This endorsement restricts coverage and introduces two
potential limitations. It first alters the roof valuation from replacement cost
to actual cash value. It also excludes wind or hail damage to the roof if it is
merely superficial or cosmetic. The premises must be listed along with the
selected limitation(s).
This endorsement
broadens the property and/or income coverage listed in the schedule to cover
losses related to radiation. The loss must stem from another covered cause of
loss for coverage to apply. However, broad coverage contamination does not
require a separate covered cause of loss.
(10
12 edition)
This endorsement provides coverage for physical damage and
business income loss caused by sewer, drain, sump water, or waterborne
discharges, but excludes flood-related discharges. A limit must be provided on
the endorsement schedule, which may or may not be subject to an annual
aggregate limit depending on the entries made.
This endorsement was
withdrawn in 2001. CP 10 40–Earthquake and Volcanic Eruption Endorsement now
provides this coverage.
(02
19 edition)
This endorsement covers
direct damage and business income loss caused by earthquakes and volcanic
eruptions. When attached to the policy, the Earth Movement Exclusion is waived,
except for damage from tidal waves or tsunamis, which remains excluded.
A separate deductible
may apply for earthquake and volcanic eruption, as detailed in the endorsement.
If only Earthquake – Sprinkler Leakage coverage is selected, the deductible is the
same as the fire deductible specified in the policy.
Related Article: Earthquake
and Volcanic Eruption Coverage
(02 19 edition)
This endorsement does
not cover losses from any Earthquake or Volcanic Eruption that happened before
the insurance start date. However, it will cover losses from Earthquake or
Volcanic Eruption occurring on or after the start date, as long as the series of
shocks or eruptions began within 72 hours before the start date.
Related Article: Earthquake
and Volcanic Eruption Coverage
(10 12 edition) (Use with CP 10 30)
Building materials meant to be incorporated into the
insured’s building are covered against theft when this endorsement is applied.
However, coverage is limited by the amount specified in the endorsement
schedule and is subject to the deductible. This endorsement is necessary
because theft coverage under CP 10 30 does not include this property.
(02 19 edition)
Unlike the CP 10 40
endorsement, this endorsement provides a sub-limit for direct damage and
business income loss resulting from Earthquake and Volcanic Eruption, which is
lower than the main policy limits. This form also uses a percentage deductible
instead of a flat deductible.

and Volcanic Eruption Coverage
(10 12 edition) (Use with CP 10 30)
This form adds
equipment breakdown as a covered peril when using the Special Form – CP 10 30.

Property. It covers damage caused by floating ice and collisions with vessels or
floating objects.
This general purpose
endorsement is used to list and summarize changes in endorsements and premiums
for a commercial property coverage form or policy.
These supplemental
declarations were withdrawn with the 10 00 edition and replaced by CP DS 01.
(09
17 change)
This endorsement covers
only theft losses. It excludes coverage for theft if the scheduled burglary and
robbery safeguards are not operational at the time of loss. 'In working
order' means the system is turned on and active during non-work hours and when
the premises is unoccupied.

the described systems are not in working order at the time of loss.
This endorsement was
withdrawn with the 10 00 edition and replaced by CP DS 02.

withdrawn and replaced by CP 12 70.
This endorsement is
necessary when property insured under a commercial property coverage form is
also covered by boiler and machinery or equipment breakdown insurance from
different carriers. It clarifies how losses under both policies will be
settled, ensuring prompt compensation to the insured and encouraging insurers
to resolve coverage disputes promptly.
(10 12 edition)
This coverage provides business income protection for the insured if their suppliers, customers, or other dependent properties suffer a loss that interrupts the supply chain, especially involving foreign suppliers or providers. It is intended to cover the income loss the insured experiences because of these dependent properties, even if they are outside the usual coverage territory. Electronic data losses are not included under this form.

number, the coinsurance, and the causes of loss form that apply. The tenant is

This coverage protects
a business against loss of income or extra expenses incurred when a key
dependent property experiences covered physical damage. The Limited Form

(10 12 edition)
This endorsement
enables the insured to fully exclude payroll costs for specific employee
groups. These costs can be entirely excluded or limited to certain days. The
10 12 edition removes the term “ordinary payroll" and offers more
flexibility with new scheduling options. This allows the insured to
maintain a lower limit in exchange for a premium surcharge.
This endorsement
excludes the costs of power, heat, or refrigeration used in production
operations from continuing business expenses. If utility payments do not
continue after a loss, the insured may include this endorsement and subtract
these costs from the business income limit of insurance. This allows the
insured to maintain a lower insurance limit in exchange for a premium
surcharge, often resulting in a lower net premium.
This endorsement
recognizes that many rental properties are seasonal. Coverage only applies
during the specified months and within the listed limits, and only if the
insured either occupies the property or rents it to others under a written
agreement.

(09
17 edition)
This endorsement extends the restoration period to
include the additional time needed to rebuild or repair damaged property to
comply with building codes or laws at the time of the loss. This coverage is
important since standard commercial property policies typically do not cover
the additional time required to comply with new building codes.
Related Article: CP 15
31–Ordinance or Law–Increased Period of Restoration
This endorsement allows the insured to modify the
limitations on civil authority coverage, extending the restoration period

Business income
coverage forms do not include loss of income caused by damage to radio or
television antennas. This endorsement removes the exclusion. The 10 12
edition had minor editorial changes that do not impact coverage.
This endorsement was
withdrawn in the 06 07 edition.
This endorsement modifies a commercial property
policy by changing the waiting period for business income coverage, allowing
the insured to either reduce it from the standard 72 hours to 24 hours or
eliminate it entirely.
Related Article: CP 15
56–Business Income Changes–Beginning of the Period of Restoration
This endorsement can
only be included when IL 09 35–Exclusion of Certain Computer-Related Losses is
attached. It reduces the exclusion by permitting an annual aggregate limit of
