PBT

Business Context and Reporting Period

Company: Permian Basin Royalty Trust (PBT)
Reporting Period: Fiscal year ended December 31, 2005
Structure: An express trust created under Texas law, holding net overriding royalty interests in oil and gas properties. The Trust has no employees; Bank of America, N.A. serves as Trustee.
Assets: The Trust holds a 75% net overriding royalty in the Waddell Ranch properties (Crane County, Texas) and a 95% net overriding royalty in various Texas Royalty properties. Operations are managed by Burlington Resources Oil & Gas Company LP (BROG) and Riverhill Energy Corporation.

Key Financial Metrics

Production & Pricing (2005):

• Total Oil Production: 827,275 barrels (Royalty interest)
• Total Gas Production: 3,608,778 Mcf (Royalty interest)
• Average Oil Price: $49.20 per barrel
• Average Gas Price: $7.11 per Mcf

Capital Expenditures (Waddell Ranch): $14.7 million in 2005. Budgeted for 2006 is approximately $30.3 million, representing a 106% increase driven by a planned increase in drilling wells (18 new wells in 2006 vs. 6 in 2005).

Material Changes vs. Prior Period

• Revenue Growth: Royalty income increased 39.9% from 2004 to 2005, driven primarily by significant increases in crude oil and natural gas prices.
• Price Increases: Average oil prices rose from $36.25 in 2004 to $49.20 in 2005. Average gas prices rose from $5.53 to $7.11.
• Reserve Revisions: Upward revisions to proved reserves and discounted future net cash flows were recorded, largely attributable to higher commodity prices.
• Operating Costs: Lease operating expenses for Waddell Ranch increased 13% year-over-year, primarily due to higher electrical costs.
• Corporate Activity: On December 12, 2005, Burlington Resources Inc. (BRI) and ConocoPhillips announced a proposed transaction for ConocoPhillips to acquire BRI.

Outlook, Risks, and Contingencies

Outlook: The Trust anticipates increased capital expenditures in 2006 ($30.3 million budget) to support development. However, future distributions remain highly dependent on volatile oil and gas prices and the operators' willingness to invest in maintenance and development.

Key Risks:

• Price Volatility: Distributions are directly tied to commodity prices, which fluctuate based on global economic conditions, geopolitics, and supply/demand.
• Depleting Assets: The underlying properties are mature and depleting. Without continued development by operators, production will decline.
• Lack of Control: Unit holders and the Trustee have no influence over the operations, development, or abandonment decisions of the underlying properties.
• Accounting Basis: Financial statements are prepared on a modified cash basis, not GAAP.
• Termination: The Trust must sell its royalties and terminate if net revenue falls below $1,000,000 per year for two consecutive years.

Contingencies: The Trustee may establish cash reserves for contingent liabilities. If production costs exceed gross proceeds in any month, the excess is recovered from future proceeds before payments to the Trust resume.

Investor Verification Checklist

• Commodity Prices: Verify current and projected crude oil and natural gas prices, as these are the primary drivers of cash flow.
• Operator Capital Plans: Confirm the execution of the 2006 drilling program by BROG and Riverhill Energy, as failure to invest will accelerate reserve depletion.
• ConocoPhillips Acquisition: Monitor the status of the proposed acquisition of BRI by ConocoPhillips and any potential impact on the management of the underlying properties.
• Reserve Estimates: Review the independent engineer's report (Cawley, Gillespie & Associates) for changes in proved reserve quantities and the assumptions used (prices, costs).
• Cost Inflation: Assess the impact of rising operating costs (specifically electricity and fuel surcharges) on net proceeds.
