Carrizo Oil & Gas, Inc.
2001 Annual Report
 

     FAS 142 will apply to all acquired intangible assets whether acquired singly, as part of a group, or in a business combination. The statement will supersede Accounting Principals Board, ("APB"), Opinion No. 17, "Intangible Assets," and will carry forward provisions in APB Opinion No. 17 related to internally developed intangible assets. Adoption of FAS 142 will result in ceasing amortization of goodwill. All of the provisions of the statement should be applied in fiscal years beginning after December 15, 2001 to all goodwill and other intangible assets recognized in an entity's statement of financial position at that date, regardless of when those assets were initially recognized. The Company does not have any goodwill or intangible assets recorded as of December 31, 2001 and does not expect the adoption of this standard to have a material impact on its financial
position or results of operations.

     In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." The statement requires entities to record the fair value of a liability for legal obligations associated with the retirement of obligations of tangible long-lived assets in the period in which it is incurred. When the liability is initially recorded, the entity increases the carrying amount of the related long-lived asset. Accretion of the liability is recognized each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years beginning after June 15, 2002, with earlier application encouraged. The Company is currently evaluating the effect of adopting Statement No. 143 on its financial statements and has not determined the timing of adoption and does not expect the adoption of this standard to have a material impact on its financial position or results of operations.

     In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS No. 144"). SFAS No. 144 addresses the financial accounting and reporting for the impairment or disposal of long-lived assets. SFAS No. 144 supersedes SFAS No. 121 but retains its fundamental provisions for the (a) recognition/measurement of impairment of long-lived assets to be held and used and (b) measurement of long-lived assets to be disposed of by sale. SFAS 144 also supercedes the accounting/reporting provisions of APB Opinion No. 30 for segments of a business to be disposed of but retains the requirement to report discontinued operations separately from continuing operations and extends that reporting to a component of an entity that either has been disposed of or is classified as held for sale. SFAS No. 144 is effective for the Company beginning in 2002. The Company is currently evaluating the impact of this new standard.

CRITICAL ACCOUNTING POLICIES

OIL AND NATURAL GAS PROPERTIES

     Investments in oil and natural gas properties are accounted for using the full-cost method of accounting. All costs directly associated with the acquisition, exploration and development of oil and natural gas properties are capitalized. Such costs include lease acquisitions, seismic surveys, and drilling and completion equipment. The Company proportionally consolidates its interests in oil and gas properties. During 1999, the Company also capitalized as oil and natural gas properties $139,910 of deferred compensation related to stock options granted to personnel directly associated with exploration activities. No deferred compensation cost was capitalized in 2000 or 2001. Additionally, the Company capitalized compensation costs for employees working directly on exploration activities of $581,000, $886,000 and $1,021,000 in 1999, 2000 and 2001, respectively.

     Oil and natural gas properties are amortized based on the unit-of-production method using estimates of proved reserve quantities. Investments in unproved properties are not amortized until proved reserves associated with the projects can be determined or until impairment occurs. Unevaluated properties are evaluated periodically for impairment on a property-by-property basis. If the results of an assessment indicate that the properties are impaired, the amount of impairment is added to the proved oil and natural gas property costs to be amortized. The amortizable base includes estimated future development costs and, where significant, dismantlement, restoration and abandonment costs, net of estimated salvage values. The depletion rate per thousand cubic feet equivalent (Mcfe) for 1999, 2000 and 2001, was $1.00, $1.03 and $1.15, respectively.

     Dispositions of oil and gas properties are accounted for as adjustments to capitalized costs with no gain or loss recognized, unless such adjustments would significantly alter the relationship between capitalized costs and proved reserves.

     The net capitalized costs of proved oil and gas properties are subject to a "ceiling test," which limits such costs to the estimated present value, discounted at a 10% interest rate, of future net revenues from proved reserves, based on current economic and operating conditions. If net capitalized costs exceed this limit, the excess is charged to operations through depreciation, depletion and amortization. No write-down of the Company's oil and natural gas assets was necessary in 1999, 2000 or 2001. Based on oil and gas prices in effect on December 31, 2001, the unamortized cost of oil and gas properties exceeded the cost center ceiling. As permitted by full cost accounting rules, improvements in pricing subsequent to December 31, 2001 removed the necessity to record a ceiling writedown. Using prices in effect on December 31, 2001 the pretax writedown would have been approximately $700,000. Because of the volatility of oil and gas prices, no assurance can be given that the Company will not experience a ceiling test writedown in future periods.

     Depreciation of other property and equipment is provided using the straight-line method based on estimated useful lives ranging from five to 10 years.
