Journal Entries to Correct Errors

The following are independent errors made by a company that uses the periodic inventory system:

a.	Goods in transit, purchased on credit and shipped FOB destination, $10,000, were included in purchases but not in the physical count of ending inventory.
b.	Purchase of a machine for $2,000 was expensed. The machine has a 4-year life, no residual value, and straightline depreciation is used.
c.	Wages payable of $2,000 were not accrued.
d.	Payment of next years rent, $4,000, was recorded as rent expense.
e.	Allowance for doubtful accounts of $5,000 was not recorded. The company normally uses the aging method.
f.	Equipment with a book value of $70,000 and a fair value of $100,000 was sold at the beginning of the year. A 2-year, non-interest-bearing note for $129,960 was received and recorded at its face value, and a gain of $59,960 was recognized. No interest revenue was recorded and 14% is a fair rate of interest.

Required:

Prepare the correcting journal entries if the company discovers each error 2 years after it is made and it has closed the books for the second year. Ignore income taxes.
