Carrizo Oil & Gas, Inc.
2001 Annual Report
 

CONCENTRATION OF CREDIT RISK

     Substantially all of the Company's accounts receivable result from oil and natural gas sales or joint interest billings to third parties in the oil and natural gas industry. This concentration of customers and joint interest owners may impact the Company's overall credit risk in that these entities may be similarly affected by changes in economic and other conditions. Historically, the Company has not experienced credit losses on such receivables.

VOLATILITY OF OIL AND NATURAL GAS PRICES

     The Company's revenues, future rate of growth, results of operations, financial condition and ability to borrow funds or obtain additional capital, as well as the carrying value of its properties, are substantially dependent upon prevailing prices of oil and natural gas. Historically, the markets for oil and natural gas have been volatile, and such markets are likely to continue to be volatile in the future. Prices for oil and natural gas are subject to wide fluctuation in response to relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty and a variety of additional factors that are beyond the control of the Company. These factors include the level of consumer product demand, weather conditions, domestic and foreign governmental regulations, the price and availability of alternative fuels, political conditions in the Middle East, the foreign supply of oil and natural gas, the price of foreign imports and overall economic conditions. It is impossible to predict future oil and natural gas price movements with certainty. Declines in oil and natural gas prices may materially adversely affect the Company's financial condition, liquidity, and ability to finance planned capital expenditures and results of operations. Lower oil and natural gas prices also may reduce the amount of oil and natural gas that the Company can produce economically. Oil and natural gas prices have declined in the recent past and there can be no assurance that prices will recover or will not decline further. See "Business and Properties -- Marketing".

     The Company periodically reviews the carrying value of its oil and natural gas properties under the full cost accounting rules of the Commission. Under these rules, capitalized costs of proved oil and natural gas properties may not exceed the present value of estimated future net revenues from proved reserves, discounted at 10 percent. Application of this ceiling test generally requires pricing future revenue at the unescalated prices in effect as of the end of each fiscal quarter and requires a write-down for accounting purposes if the ceiling is exceeded, even if prices were depressed for only a short period of time. The Company
may be required to write down the carrying value of its oil and natural gas properties when oil and natural gas prices are depressed or unusually volatile. On December 31, 1998, the Company recorded a full cost ceiling test write down of its oil and natural gas properties of $20.3 million because its carrying cost of proved reserves was in excess of the present value of estimated future net revenues from those reserves. If additional write-downs are required, they would result in additional charges to earnings, but would not impact cash flow from operating activities. Once incurred, a write-down of oil and natural gas properties is not reversible at a later date. Based on oil and gas prices in effect on December 31, 2001, the unamortized cost of our oil and gas properties exceeded the cost center ceiling. In accordance with 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 "ceiling" writedown would have been approximately $700,000.

     The Company typically uses fixed rate swaps and costless collars to hedge its exposure to material changes in the price of natural gas and crude oil. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated cash flow hedges to forecasted transactions. The Company also formally assesses, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged transactions.

     The Company's Board of Directors sets all of the Company's hedging policy, including volumes, types of instruments and counterparties, on a quarterly basis. These policies are implemented by management through the execution of trades by either he President or Chief Financial Officer after consultation and concurrence by the President, Chief Financial Officer and Chairman of the Board. The master contracts with the authorized counterparties identify the President and Chief Financial Officer as the only Company representatives authorized to execute trades. The Board of Directors also reviews the status and results of hedging activities quarterly.

     In November 2001, the Company had costless collars with an affiliate of Enron Corp., designated as hedges, covering 2,553,000 MMBtu of gas production from December 2001 through December 2002. The value of these derivatives at that time was $759,000. Because of Enron's financial condition, the Company concluded that the derivatives contracts no longer qualified for hedge accounting treatment. As required by SFAS No. 133, the value of these derivative instruments as of November 2001 ($759,000) was recorded in accumulated other comprehensive income and will be reclassified into earnings over the original term of the derivative instruments. An allowance for the related asset was charged to other expense. At December 31, 2001, $706,000 remained in accumulated other comprehensive income.
