Compute the percentage of fixed asset cost that has been depreciated and a description of what it implies about the length of time the assets have been depreciated.

• Suncor Energy Inc 

Percentage of fixed asset cost that has been depreciated = (Accumulated depreciation ÷ Property, Plant, and Equipment) × 100
2019: (52,524,000,000 ÷ 125,164,000,000) × 100 = 42%
42% of the cost of the fixed assets has been depreciated. This implies that the assets have been depreciated for almost half of their useful lifetime.

• Amplify Energy Corp

The percentage of fixed costs is as below:

Particulars	2019	2018
Depreciation costs	62000	65832
Fixed assets	819667	778881
% fixed costs	8%	8%

The depreciation is around 8% of fixed assets in each year and the useful life is approx. 12.5 years.

• Ultra Petroleum Corporation

Accumulated Depreciation= $16,313 thousand

PP&E= $26,092 thousand

Percentage that has been depreciated= 16,313/26,092= 0.625 or 62.5%

This percentage means that 62.5% of the Property, Plant, and Equipment asset has been used up, with 100% meaning the assets will be completely used up. Therefore, PP&E have used up more than half their useful life, with the exception of Land, as the useful life is unlimited, and there is no depreciation applied

• Nabors Industries Ltd

Accumulated Depreciation: $8,685,073,000

Property, Plant & Equipment: $4,930,549,000

Accumulated Depreciation ÷ Property, Plant, and Equipment) × 100

Depreciation Percentage: 17.6% of the cost of fixed assets was depreciated meaning the asset still has a long way to go before the end of its life.
