The trial balance is a list of all T-accounts with a balance.
That means that permanent T-accounts (assets, liability and equity
T-accounts) and temporary T-accounts (dividends, expenses and
revenues) are included.
Reporting the trial balance would mean that the readers
(internally and externally) would have to separate the permanent
and temporary T-accounts themselves in order to make the balance
sheet (info on financial statement) and income statement (info on
performance).
