Accounting · Ledger Posting and Principles

Statement II: A 'Compound Journal Entry' containing multiple debits or credits is posted to the ledger by debiting or crediting each individual account involved with its respective share of the transaction amount. Statement III: The Ledger is considered a 'Self-Balancing' book because the sum of all debit balances must always equal the sum of all credit balances, regardless of any errors of principle or omission. Which of the above statements are correct?
