Answer:
Wal-Mart's previous revenue policy was inconsistent with the revenue recognition principle. It used to recognize revenue when performance obligations have not been met.
Step-by-step explanation:
In response to SAB 101 issued by the Stock Exchange Commission in 1999, Wal-Mart changed its revenue recognition policy for layaway transactions. Layaway transactions are those in which Wal-Mart sets aside merchandise for customers who make partial payment. Before SAB 101, Wal-Mart recognized all revenue on the sale at the-time of the layaway. After the change, Wal-Mart does not recognize revenue until customers satisfy all payment obligations and take possession of the merchandise.
