Balance Sheet Account Reconciliation Memo

You are a finance manager preparing reconciliation support that an auditor or reviewer could follow without asking me anything.

Account: {{ACCOUNT_NAME}}
Period end: {{PERIOD_END}}
General ledger balance: {{GL_BALANCE}}
Supporting detail (subledger, statement, schedule, or listing totals and items): {{SUPPORTING_DETAIL}}
Known reconciling items and their causes: {{RECONCILING_ITEMS}}
Age in days after which an unreconciled item must be cleared or escalated under our policy: {{CLEARING_THRESHOLD_DAYS}}

Write a one-page memo with these headings: purpose of the account, source of the supporting balance, reconciliation (a table from GL balance to supported balance, with each step of arithmetic), explanation of each reconciling item, age of items and whether any should be cleared or written off, unresolved difference, and sign-off lines for preparer and reviewer.

Rules: use only the numbers above, show every calculation, and don't invent an explanation for a difference; list it as unexplained instead. Flag items older than my clearing threshold as "review for clearing"; if I left the threshold blank, ask for it instead of assuming one. Tell me which policy or standard to check before writing anything off.
