What Rating Surveillance Is
A rating is an assessment based on information available at a point in time. Surveillance is the continuing process of reviewing information about the insurer and considering whether that assessment remains appropriate. It may involve scheduled updates, follow-up questions, or contact prompted by a material development. The process is ongoing: a routine information request is not, by itself, evidence that a rating will change.
The specific process, reporting expectations, and information requests vary by agency and by insurer. An insurer should distinguish an agency’s stated requirements from its own internal reporting deadlines. Timely and consistent engagement does not guarantee a particular rating outcome; it helps ensure that the assessment can be based on current, explainable information rather than stale or conflicting figures.
Surveillance commonly combines a recurring review cycle with event-driven follow-up. A scheduled review may use periodic financial and capital information, while a significant loss, transaction, or change in financial condition may prompt additional questions between scheduled reviews. The insurer should not assume that the scheduled cycle is the only occasion on which material information matters.
What Information May Be Requested
Requests vary, but the information generally helps an analyst understand both the insurer’s current position and the reasons it may change. A useful internal inventory groups information by subject rather than treating each request as an isolated task.
| Information area | Examples of information an agency may request | What it helps explain |
|---|---|---|
| Financial results | Interim and audited statements, earnings drivers, reserve developments, and material balance-sheet changes | Current performance and the source of changes from prior periods |
| Capital and solvency | Capital measures, key assumptions, available capital, required capital, and reconciliations between reporting bases | Capital adequacy and movements in the measures used to assess it |
| Risk profile | Exposure concentrations, underwriting trends, catastrophe experience, investment risks, reinsurance arrangements, and material stress results | Which risks could affect earnings, capital, or the ability to meet obligations |
| Liquidity and funding | Liquid resources, expected cash needs, funding arrangements, and significant constraints on moving funds | Whether resources are accessible where and when needed |
| Governance and strategy | Risk oversight, controls, material strategic changes, acquisitions, and management actions | How the insurer identifies, governs, and responds to risk |
A figure without a definition can be difficult to interpret. For example, a capital amount should be accompanied by its measurement basis, date, scope, units, and whether it is preliminary or audited. A change in a ratio should identify whether the numerator, denominator, or both have changed. Consistent definitions and dates allow meaningful comparison; apparent consistency in presentation is not enough if the underlying basis has changed.
A Practical Surveillance Cycle
An insurer can manage recurring surveillance as a controlled information cycle. The exact calendar and deliverables depend on the relevant agency and the insurer’s circumstances, so the steps below describe a management approach rather than a universal agency timetable.
Record expected review periods, internal data owners, dependencies, and any agency-stated due dates. Allow time for validation and approval before information is sent.
Confirm reporting dates, units, scope, assumptions, and whether each figure is actual, estimated, or forecast. Identify changes in definitions or methods.
Compare new figures with prior submissions and source records. Explain material movements and resolve unexplained differences before communicating the information.
Provide the requested information through appropriate internal controls, record what was sent and when, and assign an owner and due date to any open follow-up.
Apply internal escalation criteria to material changes and determine whether prompt agency communication is appropriate under the insurer’s protocols and applicable expectations.
Worked Example: Organizing a Hypothetical Surveillance Calendar
A hypothetical insurer sets an internal goal to deliver quarterly information within 20 calendar days after each quarter-end. Its year-end preliminary capital figure was $620 million. The later audited figure is $612 million. Assume the reporting year is not a leap year, the internal due dates are not adjusted for holidays, and both capital figures use the same scope and measurement basis. Determine the internal quarter-end delivery dates and the size of the capital difference that should be explained.
Method. Add 20 calendar days to each quarter-end. Then compare the preliminary and audited values using the preliminary value as the denominator for a percentage difference.
For March 31, adding 20 calendar days gives April 20. For June 30, it gives July 20. For September 30, it gives October 20. For December 31, it gives January 20 of the following year. These are the insurer’s hypothetical internal targets, not universal agency deadlines.
The dollar difference is \(620-612=8\) million. The percentage difference relative to the preliminary figure is
Thus, the audited amount is $8 million, or approximately 1.29%, below the preliminary amount. The insurer should identify the source of the difference and confirm that the figures are genuinely comparable before providing an explanation. The calculation identifies the size of the variance; it does not explain its cause.
Check. Adding 20 days to each stated quarter-end produces the four dates above, and $620 million less $8 million equals the audited $612 million. The common mistake avoided is treating an internal calendar target as an agency-wide rule or describing a numerical variance as reconciled before its cause is known.
Reconciliation and the Meaning of a Capital Ratio
A recurring surveillance question is whether a changed capital measure reflects a change in available capital, required capital, or both. Define a capital ratio for a specified measurement basis as available capital \(A\) divided by required capital \(R\), where \(R>0\). This ratio is meaningful only when the numerator and denominator are measured on compatible dates, scopes, and bases.
The change in the ratio follows directly by subtracting the original ratio:
The middle expression uses a common denominator. Expanding its numerator gives \(RA+R\Delta A-AR-A\Delta R\); the \(RA\) and \(AR\) terms cancel, leaving \(R\Delta A-A\Delta R\). This shows why both movements matter. A reduction in available capital lowers the ratio, while an increase in required capital also lowers it, all else equal. A reconciliation should therefore make the movements in both measures visible.
Worked Example: Reconciling a Hypothetical Capital Update
A hypothetical insurer previously reported available capital of $620 million and required capital of $500 million. A new estimate identifies a $36 million gross loss and a separately estimated $12 million recovery, for a net reduction in available capital of $24 million. Required capital increases by $15 million. Assume all amounts use the same scope and basis, and the recovery is included once in the stated net reduction. Calculate the old and new ratios, the change in capital headroom, and the ratio change.
Method. Reconcile available capital first, update required capital separately, and then calculate each ratio using the contemporaneous numerator and denominator. Define headroom here as available capital minus required capital.
The old ratio is
The net reduction in available capital is \(36-12=24\) million, so updated available capital is \(620-24=596\) million. Updated required capital is \(500+15=515\) million. The new ratio is
Old headroom is \(620-500=120\) million. New headroom is \(596-515=81\) million, a reduction of \(120-81=39\) million. The ratio change is \(115.73\%-124.00\%=-8.27\) percentage points, rounded to two decimal places.
Check. The available-capital reduction of $24 million plus the required-capital increase of $15 million reduces headroom by $39 million, matching the calculation. The common mistake avoided is updating only the numerator: \(596/500=119.20\%\) is incorrect because required capital has also risen to $515 million. The recovery is already included in the net reduction; subtracting it again would double-count it.
Event-Driven Communication
Between scheduled reviews, a material development may change the insurer’s risk or financial position. An internal escalation protocol can help identify developments that deserve prompt assessment, such as a significant loss, a material reserve change, a capital transaction, a change in reinsurance protection, a liquidity strain, or an operational disruption. The protocol should specify who evaluates the event, what facts must be confirmed, and who has authority to decide on communication.
An internal threshold is a management control, not an agency rule. Crossing it does not by itself determine the rating consequence. It should prompt a disciplined review of the facts, relevant measures, uncertainty, and expected next steps. When communicating, distinguish confirmed amounts from estimates, state the measurement date, explain material assumptions, and identify what remains uncertain. If an earlier number has been superseded, say so explicitly rather than allowing both values to circulate without explanation.
Worked Example: Applying a Hypothetical Internal Escalation Protocol
A hypothetical insurer’s internal protocol calls for escalation if available capital falls by at least 3.0% from its latest approved amount, or if a 30-day liquidity coverage ratio falls below 1.10. The latest approved available capital is $800 million. A newly estimated loss reduces it by $21 million. Liquid resources are $132 million; the outflow forecast changes from $120 million to $126 million. The event is confirmed on Monday, June 8, and the protocol requires an internal communication decision within two business days. Assume no holidays. Determine whether either threshold is crossed and the decision deadline.
Method. Measure the capital decline against the approved capital amount. Calculate liquidity coverage as liquid resources divided by forecast 30-day outflows. Apply the stated internal thresholds exactly.
The capital decline is \(21/800=0.02625\), or 2.625%. Since \(2.625\%<3.0\%\), the capital threshold is not crossed. Before the forecast change, liquidity coverage is \(132/120=1.10\). After the change, it is
Because \(1.048<1.10\), the liquidity threshold is crossed. The event therefore requires internal escalation under the stated “capital decline or liquidity” rule, even though the capital test is not met. Counting business days after Monday, June 8, Tuesday, June 9, is day one and Wednesday, June 10, is day two. The internal decision deadline is Wednesday, June 10.
Check. The updated liquidity ratio is below 1.10, so at least one threshold is met; the two-business-day count gives Wednesday. The common mistake avoided is treating the “or” condition as if both tests must be met, or describing the insurer’s internal threshold as an agency requirement.
Why Consistency and Timeliness Matter
A surveillance assessment depends not only on the headline amounts but also on whether their meaning can be established. An unexplained difference between a preliminary estimate and an audited statement can create uncertainty about the insurer’s current position. A late response can also leave an earlier view uncorrected for longer. Conversely, a clear reconciliation helps distinguish a genuine change in risk from a change in timing, scope, assumptions, or data quality.
Good engagement does not mean presenting only favorable information or promising that a result will not change. It means providing accurate information, describing limitations, correcting errors promptly, and ensuring that internal owners know what has been communicated. Material updates should be consistent with prior definitions and explain any departure from them. This supports a more informed assessment without implying that the insurer controls the agency’s independent judgment.
Common Mistakes
- Confusing routine surveillance with a rating action. An inquiry or recurring review is part of information gathering; it does not establish that a rating change is planned.
- Mixing measurement bases. Comparing amounts from different dates, scopes, or definitions can make a ratio or movement misleading.
- Updating only one side of a ratio. If both available and required capital change, calculate the new ratio from both updated amounts.
- Sending unreconciled figures without qualification. If a preliminary value differs from an audited value, explain the difference or clearly identify it as unresolved.
- Treating internal thresholds as agency rules. Internal triggers guide management decisions; agency requirements and assessments are separate.
- Double-counting a recovery or other adjustment. First establish whether the stated loss is gross or net and whether the recovery has already been included.
Check Your Understanding
Work each problem using the stated hypothetical assumptions. Round ratios to two decimal places unless the question asks otherwise.
- A hypothetical insurer has an internal goal of submitting quarterly updates 15 calendar days after quarter-end. What are the four internal target dates? (Answer: April 15, July 15, October 15, and January 15 of the following year.)
- An insurer’s preliminary available capital is $450 million and its audited figure is $441 million, with the same scope and basis. What is the dollar and percentage difference relative to the preliminary figure? (Answer: $9 million lower; \(9/450=2.00\%\) lower.)
- A hypothetical capital ratio uses available capital of $720 million and required capital of $600 million. Available capital falls by $18 million while required capital rises by $30 million. What is the new ratio? (Answer: \(702/630=111.43\%\).)
- An internal protocol requires escalation if capital falls by at least 4.0% or liquidity coverage is below 1.05. Capital of $500 million falls by $19 million; liquid resources of $105 million cover forecast outflows that rise from $98 million to $102 million. Which threshold is crossed? (Answer: Capital falls \(19/500=3.80\%\), so that threshold is not crossed; liquidity coverage is \(105/102=1.0294\), so the liquidity threshold is crossed.)
- A hypothetical insurer’s previous capital ratio was \(840/700\). Available capital then decreases by $28 million, while required capital increases by $20 million. Calculate the new ratio and explain why using the old denominator would be wrong. (Answer: New ratio \(812/720=112.78\%\); using $700 million would be wrong because required capital has changed to $720 million.)
