Additional data: 

Lexington also placed in service on 8/1/20XB a building that cost $140,000 and has a life of 10 years, with a salvage value of $9.000. The building houses the corporate headquarters that supports oil and gas operations in the United States and non-oil and gas operations in Canada. The operations conducted in the building are general in nature and are not directly attributable to any specific exploration, development, or production activity. Since the building is not directly related to exploration, development, or production and supports activ- ities in more than one cost center, it is depreciated using straight-line depreciation for financial accounting. 

REQUIRED: 

Compute DD&A for 20XD for the following accounting methods. 

a. Tax: Assume Lexington is an independent producer (ignore percentage depletion) and accumulated depletion is $10,000. Use proved reserves to compute cost depletion. 

b. Tax: Assume Lexington is an integrated producer and accumulated depletion is $10,000. Use proved reserves to compute cost depletion. 

c. Successful efforts: Assume accumulated DD&A-proved properties is $5,000: accumulated DD&A-wells is $100.000. 

d. Full cost: Assume exclusion of all possible costs from the amortization base. Assume accumulated DD&A is $400,000. Ignore the revenue method.
