Map line-of-business codes for comparable agency reporting

One branch records commercial auto as CA, another as Fleet, and a third groups it within a package. A combined line report can make the branches appear to sell different products when they merely label them differently. A shared taxonomy is useful only if it preserves the distinctions needed for placement and renewal questions.

Define the data before the metric

One row represents: one original source line code mapped to a reporting line under a dated mapping version.

Useful fields: Source system, original line code, original label, reporting family, reporting line, package flag, allocation basis where available and taxonomy version.

Build a mapping table from the observed codes, not an imagined universal catalog. Decide whether packages remain a separate family or can be allocated using source-provided component amounts. Do not copy full package premium into every component. Keep unmapped codes as their own category until reviewed and record taxonomy changes that restate history.

Worked example

The following records and amounts are invented to show the method. They are not customer results, industry benchmarks or a forecast of Covirage performance.

Commercial auto totals $35,000 and the unallocated package remains $30,000. Assigning the package to both property and liability at its full premium would turn $65,000 of real premium into $95,000 or more across reporting lines. A visible unallocated category is more honest than false precision.

Use the result in a review

1. Have placement and operations staff review the highest-value unmapped codes before releasing a line comparison.
2. Publish the taxonomy version with the report so a shift caused by remapping is distinguishable from a business movement.
3. Choose the lowest level of detail the source supports consistently across branches, with richer local views where appropriate.

Checks before publishing

• Verify that every transaction maps to exactly one amount-bearing reporting category unless a controlled split is documented.
• Require split allocation percentages to sum to 100% for each allocated package record.
• Reconcile source premium to mapped premium, including unmapped and unallocated buckets.

Where this analysis can mislead

Product labels alone do not establish a client's actual coverage, limits or exclusions. A reporting line is a grouping for analysis; it cannot substitute for reviewing policy wording or the insured's needs.

Explore this question with your own data

Bring a small, authorized sample to Covirage for insurance agencies and brokers. Use the sample to discuss the fields and views your business needs. A dashboard or AI analyst can help explore this question when the required data and definitions are available; missing records still need to be resolved.

Upload sample data to check its structure. Keep unnecessary personal, claims and policyholder details out of an initial sample. The sample check does not establish that every analysis in this guide is available automatically.
