When a stockholder receives a certificate of stock it is posted to the credit side of his account in the stock ledger.
Transfers are posted to the stock register, when used, or direct to the stock ledger.
The stock ledger is supposed to show only the stock issued and the names of its holders.
An account should be opened in the stock ledger with Capital Stock, which account will be debited with all stock issued.
A trial balance also shows that the stock ledger balances with a credit of $20,000 treasury stock.
