Trial balance and general ledger

Also known as: TB, GL, general ledger detail, books of account

Definition

The general ledger is the complete record of a company’s accounting entries. The trial balance summarizes it as the closing balance of each account at a point in time. Together they are the starting data set for financial due diligence.

Trial balance and general ledger, explained simply

Financial statements are built from the trial balance, and the trial balance from the ledger. Diligence requests the monthly trial balances first because they allow the team to rebuild the statements, identify unusual months and trace any figure to the underlying entries.

A company that cannot produce reconciled monthly trial balances raises a reliability question about every other figure.

From transaction to financial statement

Structure

Each layer summarizes the one beneath it; diligence works back down the layers to test a figure.

Worked example

Alder Creek’s income statement shows operating expenses of $9.0 million. The monthly trial balances show that “Miscellaneous expense” rose from $20,000 a month to $180,000 in December. The general ledger detail shows the December entries relate to a one-off settlement payment. The annual total alone would not have shown this.

Alder Creek Manufacturing, Inc. is a fictional company. All figures are illustrative.

Why it matters in a deal

Monthly data exposes seasonality, trends and one-off spikes that annual totals conceal, and allows any adjustment to be traced to source.

Red flags

  • Trial balances that do not agree to the financial statements
  • Large entries in suspense or miscellaneous accounts
  • Many manual entries after month end
