Property coverage

Covered causes of loss on the Texas All-Lines exam

How the exam tests the burden of proof difference between named perils and open perils, and why that difference decides ambiguous-cause questions.

Reviewed September 2026 · Exam outline effective September 1, 2026

Named perils and open perils describe two different ways a policy grants coverage, and they place the burden of proof on different parties. That is the entire point of the distinction, and it is what the exam actually tests.

Under a named perils form, the insured must establish that the loss was caused by a peril the policy lists. Under an open perils form, coverage applies unless the insurer establishes that an exclusion removes it. When a cause cannot be determined, those two structures produce opposite outcomes.

What is tested

  • Recognizing which form the fact pattern describes before analysing the cause of loss.
  • Assigning the burden of proof to the correct party based on the form.
  • Resolving undetermined-cause fact patterns by applying the burden rather than guessing at the cause.
  • Understanding that open perils is broader than named perils but is not unlimited, because exclusions still apply.

High-yield rules

Named perils puts the burden on the insured

If the policy lists covered causes, the insured must show the loss came from a listed cause. A cause that cannot be established is not a listed cause, so coverage is not triggered.

Open perils puts the burden on the insurer

If the policy covers risks of direct physical loss subject to exclusions, coverage applies unless the insurer establishes an exclusion. An undetermined cause generally favours the insured under this structure.

Open perils is broader, not unconditional

Exclusions still remove specified causes. Candidates who treat open perils as covering everything select answers that ignore clearly applicable exclusions.

Undetermined cause is the tell

When a fact pattern goes out of its way to say the cause could not be determined, it is testing the burden of proof, not asking you to speculate about what happened.

Decision sequence

  1. 1Determine whether the policy described is a named perils or open perils form.
  2. 2Identify the cause of loss the fact pattern establishes, if any.
  3. 3If the cause is established, check it against the listed perils or the exclusions as appropriate.
  4. 4If the cause cannot be established, apply the burden of proof for the form involved.
  5. 5Confirm no exclusion removes the loss even under an open perils form.
  6. 6State the coverage conclusion based on the burden and the exclusions rather than on assumptions about the cause.

Practice questions

Written the way the examination builds items. Answer before opening the explanation.

  1. Question 1

    Property is damaged and investigation cannot establish what caused the damage. The policy is an open perils form and no exclusion is shown to apply. What is the most defensible coverage conclusion?

    1. ADeny, because the insured cannot prove a covered cause
    2. BCoverage generally applies, because the insurer has not established an applicable exclusion
    3. CDeny, because undetermined causes are excluded by definition
    4. DCoverage applies only if the insured signs a sworn statement identifying a cause
    Show answer and reasoning

    Correct answer: B — Coverage generally applies, because the insurer has not established an applicable exclusion

    Under an open perils form, coverage applies to risks of direct physical loss unless an exclusion removes them, which places the burden on the insurer. Because no exclusion has been established, the undetermined cause does not defeat coverage. Requiring the insured to prove a covered cause is the named perils burden, and there is no general exclusion for undetermined causes.

  2. Question 2

    The same undetermined-cause loss occurs under a named perils form listing specific covered causes. What changes?

    1. ANothing changes, because the loss is physical damage either way
    2. BCoverage is not triggered, because the insured has not established that a listed peril caused the loss
    3. CThe insurer must now prove an exclusion applies
    4. DThe claim converts to an open perils analysis automatically
    Show answer and reasoning

    Correct answer: B — Coverage is not triggered, because the insured has not established that a listed peril caused the loss

    A named perils form only responds to causes it lists, and the insured carries the burden of establishing that a listed cause produced the loss. An undetermined cause fails that burden, so the grant is not reached. The exclusion burden belongs to the open perils structure, and forms do not convert based on the difficulty of proof.

  3. Question 3

    A standard fire policy question asks for the first analytical step. What is it?

    1. AIdentify the form’s grant and the fire-related facts
    2. BPay replacement cost
    3. CAssume all smoke is excluded
    4. DApply the deductible
    Show answer and reasoning

    Correct answer: A — Identify the form’s grant and the fire-related facts

    Coverage analysis begins with the policy and the facts, not arithmetic. This original, source-mapped item is provided for concept practice and is not recalled exam content.

Common mistakes

  • Analysing the cause of loss without first identifying which form applies.
  • Treating open perils as covering every loss regardless of exclusions.
  • Guessing at a likely cause when the fact pattern says the cause is undetermined.
  • Applying the insurer’s exclusion burden to a named perils fact pattern.

Frequently asked

Is open perils the same as all risk?
The older all risk terminology described the same structure, but open perils or risks of direct physical loss is the more accurate phrasing because exclusions always apply. The exam favours the precise framing.
Which form is broader?
Open perils is broader because it covers causes that are not excluded rather than only causes that are listed. Broader does not mean unlimited, since exclusions still operate.
Does the burden of proof really change the answer?
Yes, and that is precisely why the exam constructs undetermined-cause questions. The identical factual scenario produces opposite conclusions depending on which party carries the burden.
