PROOF LOG #023
AMLP ROC Before Sale | 1099-DIV Box 3 Basis Erosion
High yield can look like income while basis is falling before sale.
Clients may see income while final 1099-DIV Box 3 is reducing basis before sale.
FDL makes final 1099-DIV Box 3 adjustments reviewable while the lot remains open.
AMLP can look like income while basis is already falling.
In this case, final 1099-DIV Box 3 amounts are prepared into the mother lot before sale.
FDL makes the embedded ROC path reviewable while the position is still open.
No sale yet. The basis erosion is already visible.
Proof Summary
Problem: High yield can look like income while final 1099-DIV Box 3 return of capital reduces basis before sale.
Prepared input: FDL applies the final Box 3 amounts to the same AMLP mother lot as prepared ROC basis-reduction events.
Board result: Audit Trail shows basis moving from $32.40 to $26.40, Tax Alpha Dashboard shows $300,000 of embedded ROC, and Tax Report stays quiet because no sale occurred.
Boundary: FDL does not give product advice or treat Section 19 notices as final tax inputs. It verifies prepared, final 1099-DIV Box 3 records through deterministic outputs.

EXECUTIVE PROOF
Client / Surface Risk
- high yield can look like ordinary income
- final 1099-DIV Box 3 can reduce basis before sale
- the position can remain open while future gain exposure builds
- the reviewer must prove the basis path before liquidation
FDL Registry of Truth™
- final 1099-DIV Box 3 amounts are prepared into the mother lot
- Audit Trail records annual basis-reduction events
- Tax Alpha Dashboard shows embedded ROC
- Tax Report stays quiet by design
- FDL makes before-sale basis erosion reviewable
PHASE 1 — THE YIELD SURFACE
AMLP appears as a high-yield position.
But the issue is not yield optics.
The issue is basis erosion before liquidation.
High yield can look like income while basis is falling.
PHASE 2 — THE BOX 3 PREPARED INPUT
Final 1099-DIV Box 3 amounts are prepared into the same mother lot.
CY2021, CY2022, and CY2023 reclasses reduce basis by $300,000 in total.
This is manual ROC adjustment targeting, not generic income classification.
The AMLP August 2021 mother lot remains OPEN.
PHASE 3 — THE BEFORE-SALE EXPOSURE
Tax Alpha Dashboard shows $300,000 of ROC (§301) Embedded.
Audit Trail shows the basis path moving from $32.40 to $26.40.
Tax Report stays quiet because no sale has happened.
No sale yet. The basis erosion is already visible.
FORENSIC EVIDENCE
What must remain intact
- Mother lot targetingThe Box 3 amounts must be applied to the same AMLP mother lot.
- Open-lot statusThe AMLP position remains open because no sale has occurred.
- Basis reductionThe $300,000 ROC total must reduce basis, not create a Tax Report sale row.
- Before-sale visibilityThe reviewer must see the basis path before liquidation.
What FDL makes legible
- Tax Alpha DashboardShows $300,000 of ROC (§301) Embedded.
- Audit TrailShows basis moving from $32.40 to $26.40 while the lot remains OPEN.
- Tax ReportStays quiet because no sale has occurred.
- TransactionsShows final 1099-DIV Box 3 prepared into the mother lot.
This is the point of the white-box architecture:
cash yield, final Box 3 treatment, open-lot basis erosion, and before-sale exposure stay separate and reviewable.
WHY THIS CASE MATTERS
For UHNW income sleeves, yield can look simple while basis is quietly changing underneath.
The dangerous version is not always a bad sale record.
Sometimes the position is still open, the Tax Report is quiet, and the basis path is already moving.
The question is whether the reviewer can see the basis erosion before liquidation.
WHAT FDL IS SHOWING HERE
FDL is not giving product advice.
FDL is not treating Section 19 notices as final tax inputs.
FDL shows how final 1099-DIV Box 3 amounts move through Tax Alpha Dashboard, Audit Trail, and Tax Report.
The value is making before-sale ROC basis erosion reviewable.
