Audit of accounts before adoption at board meeting

Hi,

In one of the case I have seen that BOD meeting was held on 29th of the month in which the BOD adopted the accounts and auditors signed the annual accounts on 30th of the same month i.e prima facie the BOD adopted the audited accounts but only signing by auditors was done after adoption.

Can audit be done before the Board of Directors adopt the accounts at board meeting.
