Answer:
The method used to recover costs of investment in natural resources like oil refinery, mining, timber forest is referred to as depletion.
a)
Year 1 Year 2 Year 3
Tons extracted 2,000 7,200 2,800
Depletion rate $62.50 $62.50 $62.50
Cost depletion expense $125,000 $450,000 $175,000
Note: the extract tons of coal from the deposit is limited to 12,000. So, 1,000 tons extract is deducted in the last year.
b.
Percentage depletion: This is a method of computing depletion amount based on percentage depletion rates. Percentage depletion is computed by multiplying the gross income obtained from extraction with fixed percentage depletion rates.
Calculate LC’s percentage depletion for each year.

Note: The percentage depletion is not limited to the basis in the property.
c.
