npx mdskill add anthropics/financial-services/nav-tieoutVerify LP statements against NAV data before distribution.
- Detects capital account mismatches between statements and NAV sources.
- Integrates with the nav MCP to access fund-level P&L and fees.
- Flags discrepancies using a 0.01 tolerance threshold on line items.
- Outputs a pass status when all computed values match inputs.

# NAV tie-out
Given a generated LP statement and the period's NAV pack (via the nav MCP), independently recompute the LP's capital account and compare line by line.
> **The generated statement is the thing under test.** The NAV pack is the source of truth.
## Recompute the LP capital account
```
Beginning capital (prior statement ending)
+ Contributions (capital calls paid this period)
− Distributions (cash + in-kind)
+ Allocated net income / (loss)
= LP% × (realized + unrealized P&L − management fee − fund expenses)
− Carried interest allocation (if crystallized this period)
Ending capital
```
Pull each input from the NAV pack: LP commitment %, fund-level P&L components, fee and expense totals, waterfall outputs.
## Compare
For each line on the statement, compare to your recomputed value. Tolerance: `0.01`. For each mismatch, note which input drives it (e.g., "allocated P&L differs — statement used 12.40% ownership, NAV pack shows 12.38% after the Q1 transfer").
## Additional checks
- Ending capital on this statement = beginning capital on next period's draft (if available).
- Sum of all LP ending capitals = fund NAV (within rounding).
- Commitment, unfunded, and recallable figures agree to the commitment register.
## Output
A pass/fail per line, the recomputed values alongside the statement values, and a list of flags. Do not edit the statement — the publisher acts on the flags after review.
