Financial-record review add-on
Lowest Intermediate Balance Review (LIBR)
A specialized workpaper module for organizing account activity in a form that supports lowest intermediate balance tracing analysis.
A financial-record review add-on from FinancialProofReview.
What this is
The lowest intermediate balance rule in plain language
The lowest intermediate balance rule (LIBR) is a principle used in tracing analysis. It comes up when deposits from different sources have been mixed in the same account — commingled — and a reviewer needs to evaluate how much of a particular source's money can still be traced to a later withdrawal. The principle is straightforward: a withdrawal from a commingled account can only be traced back to a target deposit up to the lowest balance the account reached between the time of the target deposit and the time of the withdrawal in question.
That lowest balance — the lowest intermediate balance — is the ceiling on what can be attributed to the target deposit. If the account dropped below the target-deposit amount at any point between the deposit and the withdrawal, the full deposit amount may not be available to support the tracing argument, regardless of subsequent deposits from other sources.
Preparing a LIBR schedule requires a complete transaction-level record: every deposit, every withdrawal, and every resulting running balance, in chronological order, across the full relevant period. Without a complete record, any LIBR-style analysis has gaps, and gaps affect whether a clean LIBR schedule can be prepared at all. LIBR analysis is used in trust and estate tracing, divorce financial tracing, fraud and restitution matters, fiduciary disputes where fund sources are contested, and other commingled-fund matters.
Why it matters
Why the schedule matters before the argument
In commingled-fund matters, showing that a target deposit was made is often not enough. What matters is whether the deposited money was still in the account when the disputed transaction occurred. A deposit followed by a near-zero balance, followed later by new deposits from other sources, does not produce a clean trace back to the original target.
Without a LIBR schedule organizing the account activity in the right form, reviewers and counsel may not be able to evaluate whether a tracing argument is supportable given the actual account history. A LIBR schedule does not make the tracing argument — it organizes the record so the argument can be evaluated against what the records show. Applicable contexts include trust and estate accounting disputes, divorce asset tracing, fraud restitution matters, commingled business and personal funds, and fiduciary disputes where the source of specific funds is contested.
What records are involved
Documents the review consults
A LIBR schedule depends on a complete transaction-level record for the account during the relevant period. The review consults:
- Complete bank statements for the relevant account(s), covering the full relevant period without gaps
- Check images and deposit slips where available
- Wire transfer records for incoming and outgoing transactions
- Account-opening records and ownership documentation
- Records identifying the source of specific deposits (payroll, transfer, gift, settlement, sale proceeds, etc.)
- Records for related accounts if funds moved between accounts during the period
- Any prior tracing analysis, accounting, or workpaper identifying target funds
- Records identifying the transaction(s) being traced to or from the account
How a review handles this
Building the chronology and the schedule
The review starts by building a complete transaction-level chronology of the account: every deposit, every withdrawal, every resulting running balance, in date order. The chronology has to be continuous through the relevant period. Period gaps — missing statements, missing production periods, or partial statements that omit detail entries — are identified and noted explicitly, because gaps in the chronology affect the reliability of any LIBR schedule built on top of it.
With the chronology in hand, the review identifies the target deposit or deposits being traced — the deposits whose subsequent treatment is at issue — along with their recorded entry dates and amounts. For each target deposit, the review then determines whether the account balance dropped below the deposit amount at any point between the deposit date and the date of the withdrawal in question. The lowest intermediate balance reached in that window is documented for each relevant period.
The output is a LIBR schedule in workpaper form: a running balance table, a lowest-intermediate-balance column tied to each target deposit, explicit notation for any period gaps that affect the schedule, and a list of follow-up questions for the records custodian where additional records are needed to complete the picture. The workpaper supports LIBR analysis — it organizes the record in a form suitable for LIBR review. It does not determine whether the lowest intermediate balance rule applies to the specific legal matter; that is a question for counsel.
What the review can produce
Workpaper outputs for LIBR review
- Complete transaction chronology (date, description, debit, credit, running balance)
- Lowest-intermediate-balance schedule
- Gap notation (periods with missing records that affect the schedule)
- Target-deposit tracking table (deposit date, amount, lowest subsequent balance)
- Missing-record list with follow-up paths
- Source-identification notes for traced deposits where documentation exists
- Workpaper-style findings with methodology notes
- Follow-up questions for counsel, records custodian, or counterparty
Boundaries
What this review does not do
FinancialProofReview prepares workpaper-style LIBR schedules that organize account activity for review. The schedules do not determine whether the lowest intermediate balance rule applies to any specific legal matter — that is a legal question for counsel. The workpapers do not constitute expert testimony, a legal opinion, a calculation of damages, or a guaranteed tracing result. The usefulness of any LIBR schedule depends on the completeness of the available account records. Gaps in the account history will be noted but cannot be filled from outside the records.
Methodology
Built on StatementProof workpapers
StatementProof is the structured workpaper system behind FinancialProofReview. Each engagement runs through the same disciplined process: source documents are indexed, transactions are reconciled, and findings are organized into reviewer-grade workpapers rather than narrative memos.
FinancialProofReview engagements are led by a Certified Fraud Examiner (CFE) with subject-matter expertise in forensic accounting, fraud examination, and financial-record review. Reviews are conducted from a fraud-examination perspective and produce workpaper-style analysis, summaries, timelines, and issue lists. The work is financial-record review support, not legal advice, law-enforcement authority, charging decisions, or testimony.
The methodology is operated by HopkinsForensic, an independent forensic-accounting firm.
Start the review
Start with the account records available
If the account records are complete or partially complete, a LIBR workpaper can be prepared from what exists. If records are missing, the first step is identifying the gaps.
About this review service
FinancialProofReview and HopkinsForensic provide forensic accounting and financial-record review support. They are not a law firm and do not provide legal advice, expert testimony, or legal opinions. The lowest intermediate balance rule is a legal doctrine; whether it applies to any specific matter is a question for counsel. No review outcome is guaranteed. The usefulness of any review depends on the records available.
