(a Delaware limited partnership) Notes to Financial Statements 1. Organization Southwest Oil & Gas Income Fund X-B, L.P. was organized under the laws of the state of Delaware on November 27, 1990 for the purpose of acquiring producing oil and gas properties and to produce and market crude oil and natural gas produced from such properties for a term of 50 years, unless terminated at an earlier date as provided for in the Partnership Agreement. The Partnership sells its oil and gas production to a variety of purchasers with the prices it receives being dependent upon the oil and gas economy. Southwest Royalties, Inc. serves as the Managing General Partner and H. H. Wommack, III, as the individual general partner. Revenues, costs and expenses are allocated as follows: Limited General Partners Partners -------- -------- Interest income on 100% - capital contributions Oil and gas sales 90% 10% All other revenues 90% 10% Organization and 100% - offering costs (1) Amortization or 100% - organization costs Property acquisition 100% - costs Gain/loss on property 90% 10% disposition Operating and 90% 10% administrative costs (2) Depreciation, depletion, and amortization of oil and gas 100% - properties All other costs 90% 10% (1) All organization costs in excess of 3% of initial capital contributions will be paid by the Managing General Partner and will be treated as a capital contribution. The Partnership paid the Managing General Partner an amount equal to 3% of initial capital contributions for such organization costs. (2) Administrative costs in any year, which exceed 2% of capital contributions shall be paid by the Managing General Partner and will be treated as a capital contribution. 2. Summary of Significant Accounting Policies The interim financial information as of June 30, 2003, and for the three and six months ended June 30, 2003, is unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. However, in the opinion of management, these interim financial statements include all the necessary adjustments to fairly present the results of the interim periods and all such adjustments are of a normal recurring nature. The interim consolidated financial statements should be read in conjunction with the Partnership's Amendment No. 1 its Annual Report on Form 10-K for the year ended December 31, 2002, filed with SEC on November 12, 2003. 3. Cumulative effect of change in accounting principle - SFAS No. 143 On January 1, 2003, the Partnership adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations ("SFAS No. 143"). Adoption of SFAS No. 143 is required for all companies with fiscal years beginning after June 15, 2002. The new standard requires the Partnership to recognize a liability for the present value of all legal obligations associated with the retirement of tangible long-lived assets and to capitalize an equal amount as a cost of the asset and depreciate the additional cost over the estimated useful life of the asset. On January 1, 2003, the Partnership recorded additional costs, net of accumulated depreciation, of approximately $174,419, a long term liability of approximately $751,711 and a loss of approximately $577,292 for the cumulative effect on depreciation of the additional costs and accretion expense on the liability related to expected abandonment costs of its oil and natural gas producing properties. At June 30, 2003, the asset retirement obligation was $781,780, and the increase in the balance from January 1, 2003 of $30,068 is due to accretion expense. The pro forma amounts for the three and six months ended June 30, 2002, which are presented on the face of the statements of operations, reflect the effect of retroactive application of SFAS No. 143. Southwest Oil & Gas Income Fund X-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 4. Cumulative effect of change in accounting principle - change in depletion method In the fourth quarter of 2002, the Partnership changed methods of accounting for depletion of capitalized costs from the units-of- revenue method to the units-of-production method. The newly adopted accounting principle is preferable in the circumstances because the units-of-production method results in a better matching of the costs of oil and gas production against the related revenue received in periods of volatile prices for production as have been experienced in recent periods. Additionally, the units-of-production method is the predominant method used by full cost companies in the oil and gas industry, accordingly, the change improves the comparability of the Partnership's financial statements with its peer group. The Partnership adopted the units-of-production method through the recording of a cumulative effect of a change in accounting principle in the amount of $7,000 effective as of January 1, 2002. The Partnership's depletion for the three and six months ended June 30, 2003 and 2002 has been calculated using the units-of-production method. There was no effect due to the change in depletion method on the quarter ended June 30, 2002. The effect of the change on the six months ended June 30, 2002 was to decrease income before cumulative effect of a change in accounting principle by $3,000 ($.28 per limited partner unit) and net income by $10,000 ($.92 per limited partner unit). 5. June 30, 2002 Restatement During the fourth quarter of 2002, the Partnership changed its method of providing for depletion from the units-of-revenue method to the units-of-production method as described in Note 4. This change in the method used to implement the Partnership's change in the manner in which it determines depletion resulted in a decrease in the Partnership's previously reported net oil and gas properties of $9,000 from $291,825 to $282,825 as of December 31, 2002 and did not effect the Partnership's 2002 cash flows from operations, investing or financing activities. The change had the following effects on the Statement of Operations for the three and six months ended June 30, 2002. Three Months Ended Six Months Ended (1) Previous Previously ly Reported Restated Reported Depreciation, depletion and amortization $10,000 20,000 17,000 Income before 25,471 18,248 21,248 cumulative effect Cumulative effect of change in accounting principle - (7,000) - Net income 25,471 11,248 21,248 Net income allocated to: Managing General 3,192 3,442 3,442 Partner General partner 355 383 383 Limited partners 21,924 7,423 17,423 Income per limited partner unit before 1.60 cumulative effect 2.01 1.33 Cumulative effect per limited partner unit - - (.65) Net income per limited partner unit .68 1.60 2.01 (1) There was no effect due to the change in depletion method on the quarter ended June 30, 2002. Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations General Southwest Oil & Gas Income Fund X-B, L.P. was organized as a Delaware limited partnership on November 27, 1990. The offering of such limited partnership interests began on December 1, 1990 as part of a shelf offering registered under the name Southwest Oil & Gas 1990-91 Income Program. Minimum capital requirements for the Partnership were met on March 1, 1991, with the offering of limited partnership interests concluding on September 30, 1991, with total limited partner contributions of $5,444,500. The Partnership was formed to acquire interests in producing oil and gas properties, to produce and market crude oil and natural gas produced from such properties, and to distribute the net proceeds from operations to the limited and general partners. Net revenues from producing oil and gas properties will not be reinvested in other revenue producing assets except to the extent that production facilities and wells are improved or reworked or where methods are employed to improve or enable more efficient recovery of oil and gas reserves. Increases or decreases in Partnership revenues and, therefore, distributions to partners will depend primarily on changes in the prices received for production, changes in volumes of production sold, lease operating expenses, enhanced recovery projects, offset drilling activities pursuant to farm-out arrangements, sales of properties, and the depletion of wells. Since wells deplete over time, production can generally be expected to decline from year to year. Well operating costs and general and administrative costs usually decrease with production declines; however, these costs may not decrease proportionately. Net income available for distribution to the partners is therefore expected to fluctuate in later years based on these factors. Based on current conditions, management anticipates performing drilling projects and workovers during the years 2003 and 2004 to enhance production. The Partnership may have an increase in production volumes for the years 2003 and 2004; otherwise, the Partnership will most likely experience the historical production decline, which has approximated 8% per year. Oil and Gas Properties Oil and gas properties are accounted for at cost under the full-cost method. Under this method, all productive and nonproductive costs incurred in connection with the acquisition, exploration and development of oil and gas reserves are capitalized. Gain or loss on the sale of oil and gas properties is not recognized unless significant oil and gas reserves are involved. In the fourth quarter of 2002, the Partnership changed methods of accounting for depletion of capitalized costs from the units-of-revenue method to the units-of-production method. The newly adopted accounting principle is preferable in the circumstances because the units-of- production method results in a better matching of the costs of oil and gas production against the related revenue received in periods of volatile prices for production as have been experienced in recent periods. Additionally, the units-of-production method is the predominant method used by full cost companies in the oil and gas industry, accordingly, the change improves the comparability of the Partnership's financial statements with its peer group. Should the net capitalized costs exceed the estimated present value of oil and gas reserves, discounted at 10%, such excess costs would be charged to current expense. As of June 30, 2003, the net capitalized costs did not exceed the estimated present value of oil and gas reserves. Critical Accounting Policies Full cost ceiling calculations The Partnership follows the full cost method of accounting for its oil and gas properties. The full cost method subjects companies to quarterly calculations of a "ceiling", or limitation on the amount of properties that can be capitalized on the balance sheet. If the Partnership's capitalized costs are in excess of the calculated ceiling, the excess must be written off as an expense. The Partnership's discounted present value of its proved oil and natural gas reserves is a major component of the ceiling calculation, and represents the component that requires the most subjective judgments. Estimates of reserves are forecasts based on engineering data, projected future rates of production and the timing of future expenditures. The process of estimating oil and natural gas reserves requires substantial judgment, resulting in imprecise determinations, particularly for new discoveries. Different reserve engineers may make different estimates of reserve quantities based on the same data. The Partnership's reserve estimates are prepared by outside consultants. The passage of time provides more qualitative information regarding estimates of reserves, and revisions are made to prior estimates to reflect updated information. However, there can be no assurance that more significant revisions will not be necessary in the future. If future significant revisions are necessary that reduce previously estimated reserve quantities, it could result in a full cost property writedown. In addition to the impact of these estimates of proved reserves on calculation of the ceiling, estimates of proved reserves are also a significant component of the calculation of DD&A. While estimating the quantities of proved reserves require substantial judgment, the associated prices of oil and natural gas reserves that are included in the discounted present value of the reserves do not require judgment. The ceiling calculation dictates that prices and costs in effect as of the last day of the period are generally held constant indefinitely. Because the ceiling calculation dictates that prices in effect as of the last day of the applicable quarter are held constant indefinitely, the resulting value may not be indicative of the true fair value of the reserves. Oil and natural gas prices have historically been cyclical and, on any particular day at the end of a quarter, can be either substantially higher or lower than the Partnership's long-term price forecast that is a barometer for true fair value. In the fourth quarter of 2002, the Partnership changed methods of accounting for depletion of capitalized costs from the units-of-revenue method to the units-of-production method. The newly adopted accounting principle is preferable in the circumstances because the units-of- production method results in a better matching of the costs of oil and gas production against the related revenue received in periods of volatile prices for production as have been experienced in recent periods. Additionally, the units-of-production method is the predominant method used by full cost companies in the oil and gas industry, accordingly, the change improves the comparability of the Partnership's financial statements with its peer group. Results of Operations A. General Comparison of the Quarters Ended June 30, 2003 and 2002 The following table provides certain information regarding performance factors for the quarters ended June 30, 2003 and 2002: Three Months Ended Percenta ge June 30, Increase 2003 2002 (Decreas e) ---- ---- -------- -- Average price per $ 26.89 16% barrel of oil 23.22 Average price per mcf $ 4.99 74% of gas 2.87 Oil production in 7,500 6,900 9% barrels Gas production in mcf 10,300 10,000 3% Gross oil and gas $ 253,029 188,881 34% revenue Net oil and gas revenue $ 14,281 54,740 (74%) Partnership $ - - - distributions Limited partner $ - - - distributions Per unit distribution to limited partners $ - - - Number of limited 10,889 10,889 partner units Revenues The Partnership's oil and gas revenues increased to $253,029 from $188,881 for the quarters ended June 30, 2003 and 2002, respectively, an increase of 34%. The principal factors affecting the comparison of the quarters ended June 30, 2003 and 2002 are as follows: 1. The average price for a barrel of oil received by the Partnership increased during the quarter ended June 30, 2003 as compared to the quarter ended June 30, 2002 by 16%, or $3.67 per barrel, resulting in an increase of approximately $27,500 in revenues. Oil sales represented 80% of total oil and gas sales during the quarter ended June 30, 2003 as compared to 85% during the quarter ended June 30, 2002. The average price for an mcf of gas received by the Partnership increased during the same period by 74%, or $2.12 per mcf, resulting in an increase of approximately $21,800 in revenues. The total increase in revenues due to the change in prices received from oil and gas production is approximately $49,300. The market price for oil and gas has been extremely volatile over the past decade, and management expects a certain amount of volatility to continue in the foreseeable future. 2. Oil production increased approximately 600 barrels or 9% during the quarter ended June 30, 2003 as compared to the quarter ended June 30, 2002, resulting in an increase of approximately $13,900 in revenues. Gas production increased approximately 300 mcf or 3% during the same period, resulting in an increase of approximately $900 in revenues. The total increase in revenues due to the change in production is approximately $14,800. Costs and Expenses Total costs and expenses increased to $295,777 from $163,421 for the quarters ended June 30, 2003 and 2002, respectively, an increase of 81%. The increase is a direct result of the accretion expense associated with our long term liability related to expected abandonment costs of our oil and natural gas properties, general and administrative expense, depletion expense and lease operating costs. 1. Lease operating costs and production taxes were 78% higher, or approximately $104,600 more during the quarter ended June 30, 2003 as compared to the quarter ended June 30, 2002. The increase in lease operating expense and production taxes is due to one lease that a workover was performed that needed additional repairs and maintenance performed during 2003, and the increase in production taxes is due to an increase in gross revenues during the quarter ended June 30, 2003. 2. General and administrative costs consist of independent accounting and engineering fees, computer services, postage, and Managing General Partner personnel costs. General and administrative costs increased 40% or approximately $7,700 during the quarter ended June 30, 2003 as compared to the quarter ended June 30, 2002. The increase in general and administrative expense is due to an increase in independent accounting review and audit fees. 3. Depletion expense increased to $15,000 for the quarter ended June 30, 2003 from $10,000 for the same period in 2002. This represents an increase of 50%. In the fourth quarter of 2002, the Partnership changed methods of accounting for depletion of capitalized costs from the units-of-revenue method to the units-of-production method. The newly adopted accounting principle is preferable in the circumstances because the units-of-production method results in a better matching of the costs of oil and gas production against the related revenue received in periods of volatile prices for production as have been experienced in recent periods. Additionally, the units-of-production method is the predominant method used by full cost companies in the oil and gas industry, accordingly, the change improves the comparability of the Partnership's financial statements with its peer group. There was no effect due to the change in depletion method on the quarter ended June 30, 2002. The contributing factor to the increase in depletion expense is in relation to the BOE depletion rate for the quarter ended June 30, 2003, which was $1.63 applied to 9,217 BOE as compared to $1.17 applied to 8,567 BOE for the same period. B. General Comparison of the Six Month Periods Ended June 30, 2003 and 2002 The following table provides certain information regarding performance factors for the six month periods ended June 30, 2003 and 2002: Six Months Ended Percenta ge June 30, Increase 2003 2002 (Decreas e) ---- ---- -------- -- Average price per $ 29.24 42% barrel of oil 20.61 Average price per mcf $ 5.24 132% of gas 2.26 Oil production in 13,900 14,400 (3%) barrels Gas production in mcf 20,700 21,800 (5%) Gross oil and gas $ 514,974 346,059 49% revenue Net oil and gas revenue $ 95,960 76,809 25% Partnership $ 35,000 - 100% distributions Limited partner $ 31,500 - 100% distributions Per unit distribution to limited partners $ 2.89 - 100% Number of limited 10,889 10,889 partner units Revenues The Partnership's oil and gas revenues increased to $514,974 from $346,059 for the six months ended June 30, 2003 and 2002, respectively, an increase of 49%. The principal factors affecting the comparison of the six months ended June 30, 2003 and 2002 are as follows: 1. The average price for a barrel of oil received by the Partnership increased during the six months ended June 30, 2003 as compared to the six months ended June 30, 2002 by 42%, or $8.63 per barrel, resulting in an increase of approximately $120,000 in revenues. Oil sales represented 79% of total oil and gas sales during the six months ended June 30, 2003 as compared to 86% during the six months ended June 30, 2002. The average price for an mcf of gas received by the Partnership increased during the same period by 132%, or $2.98 per mcf, resulting in an increase of approximately $61,700 in revenues. The total increase in revenues due to the change in prices received from oil and gas production is approximately $181,700. The market price for oil and gas has been extremely volatile over the past decade, and management expects a certain amount of volatility to continue in the foreseeable future. 2. Oil production decreased approximately 500 barrels or 3% during the six months ended June 30, 2003 as compared to the six months ended June 30, 2002, resulting in a decrease of approximately $10,300 in revenues. Gas production decreased approximately 1,100 mcf or 5% during the same period, resulting in a decrease of approximately $2,500 in revenues. The total decrease in revenues due to the change in production is approximately $12,800. Costs and Expenses Total costs and expenses increased to $522,517 from $327,863 for the six months ended June 30, 2003 and 2002, respectively, an increase of 59%. The increase is a direct result of the accretion expense associated with our long term liability related to expected abandonment costs of our oil and natural gas properties and general and administrative expense, depletion expense and lease operating costs. 1. Lease operating costs and production taxes were 56% higher, or approximately $149,800 more during the six months ended June 30, 2003 as compared to the six months ended June 30, 2002. The increase in lease operating expense and production taxes is due to one lease that a workover was performed that needed additional repairs and maintenance performed during 2003, and the increase in production taxes is due to an increase in gross revenues during the six months ended June 30, 2003. 2. General and administrative costs consist of independent accounting and engineering fees, computer services, postage, and Managing General Partner personnel costs. General and administrative costs increased 20% or approximately $7,800 during the six months ended June 30, 2003 as compared to the six months ended June 30, 2002. The increase in general and administrative expense is due to an increase in independent accounting review and audit fees. 3. Depletion expense increased to $27,000 for the six months ended June 30, 2003 from $20,000 for the same period in 2002. This represents an increase of 35%. In the fourth quarter of 2002, the Partnership changed methods of accounting for depletion of capitalized costs from the units-of-revenue method to the units-of-production method. The newly adopted accounting principle is preferable in the circumstances because the units-of-production method results in a better matching of the costs of oil and gas production against the related revenue received in periods of volatile prices for production as have been experienced in recent periods. Additionally, the units-of-production method is the predominant method used by full cost companies in the oil and gas industry, accordingly, the change improves the comparability of the Partnership's financial statements with its peer group. The effect of this change in method was to increase depletion expense for the six months ended June 30, 2002 by $3,000 and decrease net income for the six months ended June 30, 2002 by $10,000. The contributing factor to the increase in depletion expense is in relation to the BOE depletion rate for the six months ended June 30, 2003, which was $1.56 applied to 17,350 BOE as compared to $1.11 applied to 18,033 BOE for the same period. Cumulative effect of change in accounting principle On January 1, 2003, the Partnership adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations ("SFAS No. 143"). Adoption of SFAS No. 143 is required for all companies with fiscal years beginning after June 15, 2002. The new standard requires the Partnership to recognize a liability for the present value of all legal obligations associated with the retirement of tangible long-lived assets and to capitalize an equal amount as a cost of the asset and depreciate the additional cost over the estimated useful life of the asset. On January 1, 2003, the Partnership recorded additional costs, net of accumulated depreciation, of approximately $174,419, a long term liability of approximately $751,711 and a loss of approximately $577,292 for the cumulative effect on depreciation of the additional costs and accretion expense on the liability related to expected abandonment costs of its oil and natural gas producing properties. At June 30, 2003, the asset retirement obligation was $781,780, and the increase in the balance from January 1, 2003 of $30,068 is due to accretion expense. The pro forma amounts for the three and six months ended June 30, 2002, which are presented on the face of the statements of operations, reflect the effect of retroactive application of SFAS No. 143. Liquidity and Capital Resources The primary source of cash is from operations, the receipt of income from interests in oil and gas properties. The Partnership knows of no material change, nor does it anticipate any such change. Cash flows provided by operating activities were approximately $67,700 in the six months ended June 30, 2003 as compared to approximately $7,700 in the six months ended June 30, 2002. The primary source of the 2003 cash flow from operating activities was profitable operations. Cash flows used in investing activities were approximately $31,200 in the six months ended June 30, 2003 as compared to approximately $10,100 in the six months ended June 30, 2002. The principle use of the 2003 cash flow from investing activities was the addition of oil and gas properties. Cash flows used in financing activities were approximately $35,100 in the six months ended June 30, 2003 as compared to none in the six months ended June 30, 2002. The only use in financing activities was the distributions to partners. Total distributions during the six months ended June 30, 2003 were $35,000 of which $31,500 was distributed to the limited partners and $3,500 to the general partners. The per unit distribution to limited partners during the six months ended June 30, 2003 was $2.89. There were no distributions during the six months ended June 30, 2002. The sources for the 2003 distributions of $35,000 were oil and gas operations of approximately $67,700 and the change in oil and gas properties of approximately $(31,200), resulting in excess cash for contingencies or subsequent distributions. Since inception of the Partnership, cumulative monthly cash distributions of $5,527,571 have been made to the partners. As of June 30, 2003, $5,001,269 or $459.30 per limited partner unit has been distributed to the limited partners, representing a 92% return of the capital contributed. As of June 30, 2003, the Partnership had approximately $87,300 in working capital. The Managing General Partner knows of no unusual contractual commitments. Although the partnership held many long-lived properties at inception, because of the restrictions on property development imposed by the partnership agreement, the Partnership cannot develop its non-producing properties, if any. Without continued development, the producing reserves continue to deplete. Accordingly, as the Partnership's properties have matured and depleted, the net cash flows from operations for the partnership has steadily declined, except in periods of substantially increased commodity pricing. Maintenance of properties and administrative expenses for the Partnership are increasing relative to production. As the properties continue to deplete, maintenance of properties and administrative costs as a percentage of production are expected to continue to increase. The Managing General Partner has examined various alternatives to address the issue of depleting producing reserves. Continuing operations exposes the partnership to an inevitable decline in operating results and distributions of cash. Liquidating the partnership would result in immediate realization of cash for limited partners, but prices paid by purchasers of Partnership property in liquidation would likely include a substantial discount for risks and uncertainties of future cash flows, as well as any development risks. After reviewing various alternatives, the Managing General Partner initiated a plan to merge the Partnership and 20 other limited partnerships with and into the Managing General Partner. On October 17, 2002, the Managing General Partner filed a Registration Statement on Form S-4 with the Securities and Exchange Commission relating to this proposed merger. There is no assurance, however, that this merger will be consummated. Liquidity - Managing General Partner The Managing General Partner has a highly leveraged capital structure with approximately $124.0 million of principal due between December 31, 2002 and December 31, 2004. The Managing General Partner is constantly monitoring its cash position and its ability to meet its financial obligations as they become due, and in this effort, is continually exploring various strategies for addressing its current and future liquidity needs. The Managing General Partner regularly pursues and evaluates recapitalization strategies and acquisition opportunities (including opportunities to engage in mergers, consolidations or other business combinations) and at any given time may be in various stages of evaluating such opportunities. Based on current production, commodity prices and cash flow from operations, the Managing General Partner has adequate cash flow to fund debt service, developmental projects and day to day operations, but it is not sufficient to build a cash balance which would allow the Managing General Partner to meet its debt principal maturities scheduled for 2004. Therefore the Managing General Partner is currently seeking to renegotiate the terms of its obligations, including extending maturity dates, or to engage new lenders or equity investors in order to satisfy its financial obligations maturing in 2004. There can be no assurance that the Managing General Partner's debt restructuring efforts will be successful. In the event these efforts are unsuccessful, the Managing General Partner would need to look to other alternatives to meet its debt obligations, including potentially selling its assets. There can be no assurance, however, that the sales of assets can be successfully accomplished on terms acceptable to the Managing General Partner. The liquidity of the Managing General Partner, however, does not have a material impact on the operations of the Partnership. The partnership agreement of the Partnership allows the limited partners to elect a successor managing general partner to continue Partnership operations. Recent Accounting Pronouncements The FASB has issued Statement No. 143 "Accounting for Asset Retirement Obligations" which establishes requirements for the accounting of removal- type costs associated with asset retirements. The standard is effective for fiscal years beginning after June 15, 2002, with earlier application encouraged. This statement has been adopted by the Partnership effective January 1, 2003. The transition adjustment resulting from the adoption of SFAS No. 143 has been reported as a cumulative effect of a change in accounting principle. In April 2003, the FASB issued Statement of Financial Accounting Standards No. 149, Amendment of Statement No. 133 on Derivative Instruments and Hedging Activities ("SFAS No. 149"). SFAS No. 149 amendments require that contracts with comparable characteristics be accounted for similarly, clarifies when a contract with an initial investment meets the characteristic of a derivative and clarifies when a derivative requires special reporting in the statement of cash flows. SFAS No. 149 is effective for hedging relationships designated and for contracts entered into or modified after June 30, 2003, except for provisions that relate to SFAS No. 133 Statement Implementation Issues that have been effective for fiscal quarters prior to June 15, 2003, should be applied in accordance with their respective effective dates and certain provisions relating to forward purchases or sales of when-issued securities or other securities that do not yet exist, should be applied to existing contracts as well as new contracts entered into after June 30, 2003. Assessment by the Managing General Partner revealed this pronouncement to have no impact on the Partnership. In May 2003, the FASB issued Statement of Financial Accounting Standards No.150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity ("SFAS 150"). SFAS 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within the scope of SFAS 150 as a liability (or an asset in some circumstances). Many of those instruments were previously classified as equity. The application of SFAS 150 is not expected to have a material effect on the Partnership's consolidated financial statements. This Statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. Item 3. Quantitative and Qualitative Disclosures About Market Risk The Partnership is not a party to any derivative or embedded derivative instruments. Item 4. Controls and Procedures (a) Evaluation of Disclosure Controls and Procedures. The chief executive officer and chief financial officer of the Partnership's Managing General Partner have evaluated the effectiveness of the design and operation of the Partnership's disclosure controls and procedures (as defined in Exchange Act Rule 13a-14(c)) as of a date within 90 days of the filing date of this quarterly report. Based on that evaluation, the chief executive officer and chief financial officer have concluded that the Partnership's disclosure controls and procedures are effective to ensure that material information relating to the Partnership and the Partnership's consolidated subsidiaries is made known to such officers by others within these entities, particularly during the period this quarterly report was prepared, in order to allow timely decisions regarding required disclosure. (b) Changes in Internal Controls. There have not been any significant changes in the Partnership's internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation.
