Owen Company forgot to accrue $3,000 of salaries its employees
had earned at the end of 2019. It paid and expensed the salaries in
2020. It also, in 2019, recorded $4,000 of sales as an account
receivable; however, the sale really did not take place until 2020,
and it should have recognized the revenue in 2020. It collected the
money from the sale early in 2020.
