Manila Corp reported net incomes for a three-year period as follows:

2012	2011	2010
$240,000	$225,000	$180,000

During the 2012 year-end audit, the following items come to your attention:

1. Manila bought a truck on January 1, 2009 for $98,000 cash, with an $8,000 estimated residual value and a six-year life. The company debited an expense account for the entire cost of the asset. Manila uses straight-line depreciation for all vehicles.

2. During 2012, Manila changed from straight-line depreciation for its cement plant to double declining balance. The following calculations present depreciation on both bases:

		2012	2011	2010
Straight-line		$18,000	$18,000	$18,000
Double declining balance		23,100	30,000	36,000

The net income for 2012 was calculated using the double declining balance method.

3. In reviewing its provision for uncollectible accounts during 2012, the corporation has determined that 1% is the appropriate amount of bad debt expense to be charged to operations. The company had used 1/2 of 1% as its rate in 2011 and 2010 when the expense had been $9,000 and $6,000, respectively. Manila recorded bad debt expense using the new rate for 2012. If they had used the old rate, they would have recorded $3,000 less bad debt expense on December 31, 2012.
