Cyber, Aviation, and Other Specialty Lines

Key Takeaways

  • Specialty risks excluded from or too large for standard forms are placed with non-admitted insurers via surplus lines brokers after a diligent search, with no guaranty-fund protection.
  • Cyber policies are claims-made with a retro date, splitting first-party (breach response, ransomware, BI) from third-party (privacy liability), with sublimits and an hourly BI waiting period.
  • Aviation is excluded from auto/HO forms; hull coverage varies by in-motion/in-flight status and liability is quoted in single- or split-limit form.
  • Ocean marine covers vessels and cargo at sea (hull, cargo, freight, P&I); inland marine covers transit and floating property under the Nationwide Marine Definition.
  • General average shares a voluntary voyage-saving sacrifice among all interests, unlike particular average, which falls only on the damaged property's owner.

Cyber, Aviation, and Other Specialty Lines

The specialty-lines portion of the national exam samples coverages that fall outside the standard property and liability forms: cyber liability, aviation, ocean and inland marine, and excess/surplus placement. The unifying theme is that these risks are either excluded from standard policies or too large/unusual for the admitted market, so they require dedicated forms or the surplus lines mechanism.

Start with the regulatory framing. When a risk cannot be placed with an admitted (licensed) insurer, a specially licensed surplus lines broker may place it with a non-admitted insurer after a diligent search (commonly three declinations). Surplus lines policies are not protected by the state guaranty fund, and the insured must usually sign a disclosure acknowledging that fact.

Cyber Liability Insurance

Cyber policies respond to data breaches, ransomware, and network failures. They divide into two halves the exam tests by name:

  • First-party coverage – the insured's own losses: breach-response and notification costs, forensic investigation, business interruption from a network outage, cyber extortion/ransomware payments, and data restoration.
  • Third-party coverage – liability to others: defense and damages from privacy lawsuits, regulatory fines and penalties where insurable, and media/content liability.

Cyber is written almost exclusively on a claims-made basis with a retroactive date; a claim is covered only if the wrongful act occurred on or after the retro date and the claim is first made during the policy period. A sublimit typically caps cyber-extortion payments below the policy aggregate, and a waiting-period deductible (measured in hours) applies to business-interruption coverage rather than a dollar deductible.

Because cyber is claims-made, the exam may test tail coverage (an Extended Reporting Period) that lets an insured report claims after the policy ends for acts committed before expiration. Common cyber exclusions include prior known incidents, war/hostile-cyberattack acts, and bodily injury/property damage (which belong on the CGL). Distinguish a first-party ransomware payment, paid to the insured's own attacker, from a third-party privacy suit brought by customers whose data was exposed—both can arise from one breach but are funded by different insuring agreements and limits.

A company's cyber policy has a $2,000,000 aggregate limit, a $250,000 sublimit for cyber extortion, and an 8-hour business-interruption waiting period. The firm pays a $400,000 ransom to recover its data. How much does the extortion coverage pay before other coverages?

Aviation Insurance

Aircraft are excluded from the personal auto and homeowners forms, so aviation is its own specialty line. Two structural pieces are tested:

  • Hull coverage – physical damage to the aircraft, often split by status: in motion, not in motion, and in flight. "In motion" hull rates are higher because most losses occur during taxi, takeoff, and landing.
  • Liability coverage – bodily injury and property damage to others, frequently split as admitted (passenger) liability, non-passenger (public) liability, and property damage, and quoted with single-limit or split-limit formats.

A combined single limit (CSL) pays one pool for both BI and PD and is cleaner for severe-loss aircraft exposures, whereas split limits cap per-person, per-occurrence, and property damage separately.

Split-limit worked example. A liability policy reads $1,000,000 / $5,000,000 / $500,000 (per-person BI / per-occurrence BI / property damage). In a crash injuring four passengers with claims of $1.2M, $900K, $700K, and $400K plus $600K property damage, the per-person cap reduces the $1.2M and $700K claims to $1.0M and the occurrence total is capped at $5,000,000 for BI; property damage pays up to $500,000 of the $600,000.

Ocean and Inland Marine

Marine insurance predates the standard property forms and remains its own discipline.

Ocean marineHull, cargo, freight, and Protection & Indemnity (P&I) liability for vessels at seaGeneral average; perils of the sea
Inland marineProperty in transit and "floating" property on landISO commercial inland marine, the Nationwide Marine Definition

Inland marine grew from the Nationwide Marine Definition, which describes what can be written on inland marine forms: domestic shipments, instrumentalities of transportation/communication (bridges, tunnels, pipelines), and certain mobile or specialized property. Common inland marine forms include the Commercial Articles, Equipment (Contractors') Floater, Bailee coverage, and the Accounts Receivable and Valuable Papers forms. A signature feature is the floater—coverage that follows movable property wherever it goes.

General Average and Other Specialty Traps

  • General average (ocean marine): when cargo is voluntarily sacrificed to save the voyage, all parties with an interest in the voyage share the loss proportionally.

Contrast this with particular average, a partial loss borne only by the owner of the damaged property.

  • Umbrella/excess liability sits above underlying CGL, auto, and employers liability limits and may drop down to fill gaps; a self-insured retention (SIR) applies where no underlying coverage exists.
  • Surplus lines premiums are subject to a state surplus lines premium tax paid by the broker, and the policy must carry the non-admitted/guaranty-fund disclosure.

The broker must typically document the diligent search (often three declinations from admitted carriers) before binding with a non-admitted insurer, and may place coverage only with eligible/approved surplus lines insurers.

  • Difference in Conditions (DIC) policies fill gaps in standard property coverage—often adding flood and earthquake—and are themselves a specialty placement.

A frequent trap: confusing inland vs. ocean marine (inland = land/transit/floaters; ocean = vessels and cargo at sea) and confusing general average vs. particular average.
