Rockwell Corporation uses a periodic inventory system and has used the FIFO cost method since inception of the company in 1979. In 2021, the company decided to switch to the average cost method. Data for 2021 are as follows:

Beginning inventory, FIFO (4,800 units @ $34)				$	163,200
Purchases:
4,800 units @ $40	$	192,000
4,800 units @ $44		211,200			403,200
Cost of goods available for sale				$	566,400
Sales for 2021 (6,000 units @ $65)				$	390,000

Additional Information:

The company's effective income tax rate is 25% for all years.

If the company had used the average cost method prior to 2021, ending inventory for 2020 would have been $115,200.

8,400 units remained in inventory at the end of 2021.

Required: 1. Ignoring income taxes, prepare the 2021 journal entry to adjust the accounts to reflect the average cost method. 2. What is the effect of the change in methods on 2021 net income?
