MS Property & Casualty common mistakes
MS Property & Casualty · Understand the traps and how to avoid them.
On coinsurance penalty questions, subtracting the deductible from the loss before multiplying by the coinsurance fraction (insurance carried ÷ insurance required).
Candidates memorize the coinsurance formula as a single line and paste the deductible into the first step, because most practice word problems include a deductible and it feels like it should reduce the 'loss' figure used in the formula.
What to do instead
Routinely write the three-step order before computing: (1) loss amount, (2) coinsurance fraction applied to the loss to get the insurer's share, (3) deductible subtracted from that share. Do five problems in a row using that written order until it is automatic.
Treating insurable interest as something that must exist at policy inception for property coverage, or at time of loss for life coverage.
The two rules sound similar and study outlines often list 'insurable interest' once without splitting property from life, so the candidate applies whichever version they read last.
What to do instead
Anchor the pair with a one-line contrast you can recall under pressure: property = interest at time of loss; life = interest at inception. Rehearse with a scenario where a seller conveys a building after the policy starts.
Reading the homeowners special limits (for money, jewelry theft, firearms theft, silverware theft, business property, etc.) as a single annual aggregate cap rather than a per-occurrence cap on that category.
The limits sit in one numbered list in the policy, and candidates skim it as a summary of sublimits rather than parsing what each sublimit attaches to.
What to do instead
For each special limit, state out loud the peril or category it modifies (e.g., theft only, on premises vs. off) and that it caps that category per loss. Build a table with columns: category, limit, peril restriction.
Assuming replacement cost on a homeowners form is paid immediately, forgetting that the insurer may pay actual cash value first until the property is actually repaired or replaced, and forgetting the minimum amount-of-insurance condition tied to Coverage A.
'Replacement cost' is treated as a label for the whole policy instead of a loss-settlement option with conditions attached, so the candidate answers as if RC means a guaranteed new-for-old payout.
What to do instead
Memorize the settlement mechanics as a sequence: RC form still pays ACV initially, then withholds recoverable depreciation until replacement; and know the percentage-of-Coverage-A condition that must be met to get full RC.
On personal auto questions, assuming a vehicle furnished for the regular use of the insured or a family member is covered as a 'non-owned auto.'
Candidates lump all borrowed or borrowed-looking vehicles into 'non-owned auto' without checking the regular-use carve-out, which exists to stop people from insuring an extra household car under someone else's policy.
What to do instead
Apply a two-question test to every non-owned auto fact pattern: whose vehicle is it, and is its use temporary or regular? If regular, treat it as excluded and consider whether it must be scheduled. Drill with a pattern where a parent's extra truck is driven daily by a resident relative.
Answering commercial general liability trigger questions with occurrence-policy logic (injury or damage must happen during the policy period) when the fact pattern describes a claims-made form, or vice versa.
Occurrence forms dominate study material and most CGL fact patterns, so the candidate answers on autopilot without checking the trigger language or the presence of a retroactive date.
What to do instead
Before answering any CGL question, scan for two words: 'claims-made' or 'occurrence,' and 'retroactive date.' Write the trigger rule in the margin first, then evaluate the dates in the facts.
Using generic or out-of-state numbers (for example 15/30/5 auto liability limits, or a 30-day cancellation notice) on Mississippi questions instead of Mississippi's own requirements.
Federal minimums and large-state rules get repeated across study guides and stick in memory, and the Mississippi label on the question is skimmed rather than used to switch rule sets.
What to do instead
Keep a one-page Mississippi sheet with the state's financial responsibility limits, uninsured motorist offer/waiver rule, and the specific notice periods and producer licensing requirements, and review it immediately before any Mississippi-law section.
Treating Mississippi regulatory bodies and residual-market mechanisms as interchangeable with national models, e.g., attributing federal flood program authority or NAIC model-act status to the Mississippi Department of Insurance, or missing the state windstorm underwriting association when a coastal property question appears.
Regulatory chapters are the least familiar material and are studied last, so candidates fall back on the shape of federal or NAIC material they already know.
What to do instead
For each Mississippi entity, write one sentence on what it actually does and one example question it would generate (coastal windstorm placement, producer discipline, rate filing review). Learn entities in pairs - state vs. federal - so the wrong attribution feels wrong.
Using 'waiver' and 'estoppel' interchangeably, or labeling an applicant's statement on an application as a warranty rather than a representation.
The four contract-law terms (representation, warranty, concealment, waiver/estoppel) are usually taught as a block of definitions with no contrasting fact patterns, so recall is fuzzy under time pressure.
What to do instead
Memorize each term by its distinguishing feature: representation = statement believed true; warranty = statement guaranteed true; concealment = intentional silence on material fact; waiver = voluntary surrender of a known right; estoppel = bar from asserting a right after the other party relied on conduct. Answer with the distinguishing feature, not a definition.
Assuming the base policy form controls when an endorsement conflicts with it, or misapplying 'other insurance' clauses by treating pro rata and excess provisions as producing the same payout.
Candidates read the base form first and remember it longest, and the two other-insurance methods both sound like 'share the loss,' so the arithmetic difference gets lost.
What to do instead
Adopt two rules: endorsements amend the form and control on conflict; pro rata divides the loss by limits, excess pays only after other coverage is exhausted. Practice one split-loss calculation under each method so the numeric difference is concrete.
