CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES
NOTES TO CONSOUDATED FINANCIAL STATEMENTS
1. Basis of Presentation and Summary of Significant Accounting Policies
Description of Company
Chesapeake Energy Corporation is an oil and natural gas exploration and production company engaged in the
acquisition, exploration, and development of properties for the production of crude oil and natural gas from
underground reservoirs. Our properties are located in Oklahoma, Texas, Arkansas, Louisiana, Kansas, Montana,
Colorado, North Dakota, New Mexico and British Columbia and Saskatchewan, Canada.
Principles of Consolidation
The accompanying consolidated financial statements of Chesapeake Energy Corporation include the accounts
of our direct and indirect wholly-owned subsidiaries. All significant intercompany accounts and transactions have
been eliminated. Investments in companies and partnerships which give us significant influence, but not control,
over the investee are accounted for using the equity method. Other investments are generally carried at cost.
Accounting Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Cash Equivalents
For purposes of the consolidated financial statements, Chesapeake considers investments in all highly liquid
debt instruments with maturities of three months or less at date of purchase to be cash equivalents.
Inventory
Inventory consists primarily of tubular goods and other lease and well equipment which we plan to utilize in our
ongoing exploration and development activities and is carried at the lower of cost or market using the specific
identification method.
Oil and Gas Properties
Chesapeake follows the full-cost method of accounting under which all costs associated with property
acquisition, exploration and development activities are capitalized. We capitalizeinternal costs that can be directly
identified with our acquisition, exploration and development activities and do not include any. costs related to
production, general corporate overhead or similar activities (see note 11). Capitalized costs are amortized on a
composite unit-of-production method based on proved oil and gas reserves. As of December 31, 2000, approximately
72% of our present value (discounted at 10%) of estimated future net revenues of proved reserves was evaluated by
independent petroleum engineers, with the balance evaluated by our internal reservoir engineers. In addition, our
internal engineers evaluate all properties quarterly. The average composite rates used for depreciation, depletion and
amortization were $1.13 ($1.17 in U.S. and $0.43 in Canada) per equivalent mcf in 1998, $0.71 ($0.73in U.S. and
$0.52 in Canada) per equivalent mcf in 1999, and $0.75 ($0.76 in U.S. and $0.71 in Canada) per equivalent mcf in
2000.
Proceeds from the sale of properties are accounted for as reductions to capitalized costs unless such sales
involve a significant change in the relationship between costs and the value of proved reserves or the underlying
value of unproved properties, in which case a gain or loss is recognized. The costs of unproved properties are
excluded from amortization until the properties are evaluated. We review all of our unevaluated properties quarterly
to determine whether or not and to what extent proved reserves have been assigned to the properties, and otherwise
