16.3 Cyber, Aviation, and Other Specialty Lines

Cyber Liability Insurance

Cyber liability is the fastest-growing specialty line, covering losses from data breaches, ransomware, and network failures that standard property and liability forms exclude. It splits into two halves, a distinction the exam loves.

• First-party coverage pays the insured's own costs after a breach: forensic investigation, customer notification, credit monitoring, public relations, cyber extortion / ransomware payments, and business interruption from a network outage.
• Third-party coverage pays the insured's liability to others: privacy lawsuits, regulatory fines where insurable, and PCI-DSS (Payment Card Industry Data Security Standard) assessments.

Why a Separate Cyber Policy

A Commercial General Liability (CGL) policy responds to bodily injury and property damage, and ISO has added data-breach exclusions to clarify that loss of electronic data is not 'property damage.' Cyber policies are usually written on a claims-made basis, meaning the claim must be made during the policy period (or extended reporting period), not merely the act committed during it.

Trap: a stolen laptop is a property/crime loss, but the breach of the data on it is a cyber loss. Separate the device from the data.

First-party versus third-party cyber coverage

Cyber questions hinge on the first-party / third-party split. First-party cyber pays the insured's own costs - breach notification, forensic investigation, data restoration, business interruption from a network outage, cyber-extortion, and public-relations expense. Third-party (cyber liability) pays the insured's liability to others - regulatory fines where insurable, defense of privacy suits, and damages from a data breach affecting customers.

The standard property and CGL forms exclude most of this (electronic data is not tangible property and privacy fines are not covered), which is the entire reason a standalone cyber policy exists.

Aviation and specialty-line traps to remember

Aviation policies separate hull (physical damage to the aircraft) from liability, and liability is written either as a single combined single limit or as split limits with a per-passenger sublimit - the per-seat sublimit is the common calculation trap. Other specialty lines tested briefly: boiler and machinery / equipment breakdown (sudden mechanical or electrical breakdown the property form excludes), difference-in-conditions (fills flood/earthquake gaps), and kidnap and ransom.

The unifying theme across all specialty lines is that each one buys back a major exclusion in the standard property or liability program; match the gap to the specialty form.

Aviation Insurance

Standard CGL and business auto forms exclude aircraft, so aviation risks require specialty placement. Aviation policies separate two distinct exposures:

Liability limits may be written as a combined single limit (CSL) or split. Hull is typically valued on an agreed value basis because aircraft values are specialized and not easily set by ACV after a total loss.

Hull is further divided by status: in-flight, taxiing, and not in motion. Insurers may charge different rates or apply different deductibles to each, since the loss exposure rises sharply once the aircraft is moving under its own power.

Worked Example: Split vs. Combined Limits

An aircraft policy shows a $1,000,000 / $100,000 split liability limit: up to $1,000,000 total per occurrence, but no more than $100,000 for any single passenger's bodily injury. If three passengers are injured for $150,000 each, the insurer pays only $100,000 per passenger — $300,000 total — even though the $1,000,000 occurrence cap is not exhausted.

A combined single limit of $1,000,000 would instead allow the full $450,000 to be paid from one shared pool.

Marine and Other Specialty Lines

Standard property forms cover property at a fixed location, so mobile or in-transit property needs marine forms.

• Ocean marine — hull, cargo, freight, and protection & indemnity (P&I) for ships and ocean cargo.
• Inland marine — goods in transit over land and mobile equipment (contractors' tools, fine arts, signs); these 'floaters' follow the property wherever it goes.
• Watercraft — boats above the size limits excluded by homeowners forms need a separate boat or yacht policy.

Other specialty placements include professional liability / errors and omissions (E&O), directors and officers (D&O), and environmental / pollution coverage, all of which fill gaps standard forms exclude.

Professional Liability and D&O

Professional liability / errors and omissions (E&O) covers economic loss a client suffers from a professional's negligent act, error, or omission — distinct from the bodily injury and property damage a CGL addresses. Medical malpractice is the healthcare version.

Directors and officers (D&O) liability protects company leaders against claims arising from their management decisions (breach of fiduciary duty, mismanagement). Both are almost always claims-made, so the retroactive date and any extended reporting period (tail) are critical to read on the declarations.

Common Specialty-Line Traps

• Specialty risks are frequently placed in the surplus lines (non-admitted) market because standard carriers decline them; the policy is not backed by the state guaranty fund.
• Many specialty forms are manuscript (negotiated, non-standard) rather than ISO standard forms.
• A claims-made trigger plus a retroactive date is common in cyber, E&O, and D&O — losses before the retro date are not covered even if the claim is timely.
• Inland marine uses the nationwide marine definition to set what classes are eligible; if property is mobile, in transit, or hard to value at a fixed location, suspect inland marine.
