Cost of goods sold	P1,580,000

Although the books have been closed, your working paper trial balance is prepared showing all accounts with activity during the year. This is the first time your firm has made an examination. The January 1 and December 31 inventories appearing above were determined by the physical count of the goods on hand on those dates and no reconciling items were considered. All purchases are at FOB shipping points.

In the course of your examination of the inventory cutoff, both at the beginning and end of the year, you discovered the following facts:

Beginning of the Year

1. Invoices totaling P25,000 were entered in the voucher register in January, but the goods were received during December.

2. December invoices totaling P13,200 were entered in the voucher register in December, but goods were not received until January.
