Wacc Weight Sum Check

Check that the capital weights in a WACC build sum to one. Preparation only, not an account action.

What to provide

The equity and debt weights and the computed WACC.

How it works

1. Record the equity and debt weights.
2. Sum the weights.
3. Flag any gap from 100%.
4. Return the check without model changes.

The output

equity_weight | debt_weight | weight_sum | gap_from_100 | wacc_reliable

Worked fictional example

Fictional WACC build uses an equity weight of 65% and a debt weight of 30%: the weights sum to 95%, not 100%, a 5-point gap that makes the quoted 7.8% result unreliable.

Checks and limits

Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
