Forward-Looking Statements
     Statements included in this Form 10-Q are forward-looking statements. In addition, we and our representatives may from time to time make other oral or written statements which are also forward-looking statements.
     Such forward-looking statements include, among other things, statements regarding capital expenditures, acquisitions and dispositions, expected commencement dates of coal mining, projected quantities of future coal production by our lessees producing coal from our reserves and projected demand or supply for coal that will affect sales levels, prices and royalties realized by us.
     These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.
     You should not put undue reliance on any forward-looking statements. Please read “Item 1A Risk Factors” in this Form 10-Q and our Form 10-K for the year ended December 31, 2005 for important factors that could cause our actual results of operations or our actual financial condition to differ.

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Basis of Presentation and Organization
     The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2006 are not necessarily indicative of the results that may be expected for future periods.
     You should refer to the information contained in the footnotes included in Natural Resource Partners L.P.’s 2005 Annual Report on Form 10-K in connection with the reading of these unaudited interim consolidated financial statements.
     The Partnership engages principally in the business of owning and managing coal properties in the three major coal-producing regions of the United States: Appalachia, the Illinois Basin and the Western United States. The Partnership does not operate any mines. The Partnership leases coal reserves through its wholly owned subsidiary, NRP (Operating) LLC, (“NRP Operating”), to experienced mine operators under long-term leases that grant the operators the right to mine the Partnership’s coal reserves in exchange for royalty payments. The Partnership’s lessees are generally required to make payments to the Partnership based on the higher of a percentage of the gross sales price or a fixed price per ton of coal sold, in addition to a minimum payment.
     The general partner of the Partnership is NRP (GP) LP, a Delaware limited partnership, whose general partner is GP Natural Resource Partners LLC, a Delaware limited liability company.
2. Summary of Significant Accounting Policies
Reclassification
     Certain reclassifications have been made to the prior year’s financial statements to conform to current year classifications.
Share-Based Payment
     The Partnership adopted Statement of Financial Accounting Standards No. 123R “Share-Based Payment,” effective January 1, 2006 using the modified prospective approach. Prior to 2006, awards under our Long Term Incentive Plan have been accounted for on the intrinsic method under the provisions of APB No. 25. FAS 123R provides that grants must be accounted for using the fair value method, which requires us to estimate the fair value of the grant and charge the estimated fair value to expense over the service or vesting period of the grant. In addition, FAS 123R requires that we include estimated forfeitures in our periodic computation of the fair value of the liability and that the fair value be recalculated at each reporting date over the service or vesting period of the grant. FAS 123R required us to recognize the cumulative effect of the accounting change at the date of adoption based on the difference between the fair value of the unvested awards and the intrinsic value previously recorded. Included in operating costs and expenses was a one time charge of $661,000 which represents the cumulative effect of adopting FAS 123R as of January 1, 2006. This adjustment had the impact of reducing net income per limited partner unit for the nine month period ended September 30, 2006 by $0.02. Application of FAS 123R to prior periods did not materially impact amounts previously presented.

     At September 30, 2006, the Partnership had an outstanding balance of $63 million on its revolving credit facility, and the weighted average interest rate on the outstanding balance was 6.65%. The Partnership incurs a commitment fee on the revolving credit facility at rates ranging from 0.15% to 0.40% per annum.
     The Partnership was in compliance with all terms under its long-term debt as of September 30, 2006.
6. Net Income Per Unit Attributable to Limited Partners
     Net income per unit attributable to limited partners is based on the weighted-average number of common and subordinated units outstanding during the period and is allocated in the same ratio as quarterly cash distributions are made. Net income per unit attributable to limited partners is computed by dividing net income attributable to limited partners, after deducting the general partner’s 2% interest and incentive distributions, by the weighted-average number of limited partnership units outstanding. Basic and diluted net income per unit attributable to limited partners are the same since the Partnership has no potentially dilutive securities outstanding.
7. Related Party Transactions
     Quintana Minerals Corporation, a company controlled by Corbin J. Robertson, Jr., Chairman and CEO of GP Natural Resource Partners LLC, provided certain administrative services to the Partnership and charged it for direct costs related to the administrative services. Total expenses charged to the Partnership under this arrangement were $0.2 million for each of the three month periods ended September 30, 2006 and 2005, and $0.6 million and for each of the nine month periods ended September 30, 2006 and 2005. These costs are reflected in general and administrative expenses in the accompanying statements of income. At September 30, 2006, the Partnership had accounts payable to Quintana Minerals Corporation of $0.1 million for general and administrative expenses.
     Western Pocahontas Properties Limited Partnership, a company also controlled by Corbin J. Robertson, Jr., provides certain administrative services for the Partnership.

8. Commitments and Contingencies
Legal
     The Partnership is involved, from time to time, in various other legal proceedings arising in the ordinary course of business. While the ultimate results of these proceedings cannot be predicted with certainty, management believes these claims will not have a material effect on the Partnership’s financial position, liquidity or operations.
Environmental Compliance
     The operations conducted on the Partnership’s properties by its lessees are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted. As owner of surface interests in some properties, the Partnership may be liable for certain environmental conditions occurring at the surface properties. The terms of substantially all of the Partnership’s coal leases require the lessee to comply with all applicable laws and regulations, including environmental laws and regulations. Lessees post reclamation bonds assuring that reclamation will be completed as required by the relevant permit, and substantially all of the leases require the lessee to indemnify the Partnership against, among other things, environmental liabilities. Some of these indemnifications survive the termination of the lease. The Partnership has neither incurred, nor is it aware of, any material environmental charges imposed on it related to its properties as of September 30, 2006. The Partnership is not associated with any environmental contamination that may require remediation costs.
9. Major Lessees

10. Incentive Plans
     GP Natural Resource Partners LLC adopted the Natural Resource Partners Long-Term Incentive Plan (the “Long-Term Incentive Plan”) for directors of GP Natural Resource Partners LLC and employees of its affiliates who perform services for the Partnership. The compensation committee of GP Natural Resource Partners LLC’s board of directors administers the Long-Term Incentive Plan. Subject to the rules of the exchange upon which the common units are listed at the time, the board of directors and the compensation committee of the board of directors have the right to alter or amend the Long-Term Incentive Plan or any part of the Long-Term Incentive Plan from time to time. Except upon the occurrence of unusual or nonrecurring events, no change in any outstanding grant may be made that would materially reduce the benefit intended to be made available to a participant without the consent of the participant.
     Under the plan a grantee will receive the market value of a common unit in cash upon vesting. Market value is determined by taking the average closing price over the last 20 trading days prior to the vesting date. The compensation committee may make grants under the Long-Term Incentive Plan to employees and directors containing such terms as it determines, including the vesting period. Outstanding grants vest upon a change in control of the Partnership, the general partner, or GP Natural Resource Partners LLC. If a grantee’s employment or membership on the board of directors terminates for any reason, outstanding grants will be automatically forfeited unless and to the extent the compensation committee provides otherwise.

     A summary of activity in the outstanding grants of Partnership units for the first nine months of 2006 are as follows:
         
Outstanding grants at the beginning of the period
    211,931  
Grants during the period
    61,166  
Grants vested and paid during the period
    (13,947 )
Forfeitures during the period
    (1,540 )
 
       
Outstanding grants at the end of the period
    257,610  
 
       
     Grants typically vest at the end of a four-year period and are paid in cash upon vesting. The liability fluctuates with the market value of the Partnership units and because of changes in estimated fair value determined each quarter using the Black-Scholes option valuation model. Risk free interest rates and volatility are reset at each calculation based on current rates corresponding to the remaining vesting term for each outstanding grant and ranged from 4.50% to 4.82% and 22.70% to 26.70%, respectively at September 30, 2006. The Partnership’s historic dividend rate of 5.58% was used in the calculation at September 30, 2006. The Partnership accrued expenses related to its plans to be reimbursed to its general partner of $0.8 million and $1.2 million for the three months ended September 30, 2006 and 2005, respectively, and $3.0 million and $3.3 million for the nine month periods ended September 30, 2006 and 2005, respectively, including $661,000 in the first quarter of 2006 related to the cumulative effect of the change in accounting method discussed above. In connection with the Long-Term Incentive Plans, cash payments of $0.8 million were paid during each of the nine month periods ended September 30, 2006 and 2005. The unaccrued cost associated with the outstanding grants at September 30, 2006 was $6.4 million.
11. Distributions
     On August 14, 2006, the Partnership paid a cash distribution equal to $0.82 per unit, or $3.28 on an annualized basis, to unitholders of record on August 1, 2006.
12. Subsequent Events
     On October 17, 2006, the Partnership announced a $0.03 per unit increase in its quarterly distribution to $0.85 per unit, or $3.40 per unit on an annualized basis. The distribution is payable on November 14, 2006 to unitholders of record on November 1, 2006.
     The Partnership also announced that effective at the close of business on November 14, 2006, as expected, there will be a mandatory and automatic conversion of one-third of the currently outstanding subordinated units traded under the ticker symbol NSP into common units traded under the ticker symbol NRP. Provided all terms of the conversion set forth in the partnership agreement have been met, the remaining subordinated units will convert into common units in mid-November 2007.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     The following discussion of the financial condition and results of operations should be read in conjunction with the historical financial statements and notes thereto included elsewhere in this filing and the financial statements and footnotes included in the Natural Resource Partners L.P. Form 10-K, as filed on February 27, 2006.
Executive Overview
     We engage principally in the business of owning and managing coal properties in the three major coal-producing regions of the United States: Appalachia, the Illinois Basin and the Western United States. As of December 31, 2005, we owned or controlled approximately two billion tons of proven and probable coal reserves in eleven states and we own coal reserves that run the entire length of the Appalachian coal chain. For the nine months ended September 30, 2006, approximately 57% of the coal produced from our properties came from underground mines and approximately 43% came from surface mines.
     We lease coal reserves under long-term leases that grant operators the right to mine and sell our coal reserves in exchange for royalty payments. As of September 30, 2006, our reserves were subject to 180 leases with 69 lessees. For the nine months ended September 30, 2006, our lessees produced 40.2 million tons of coal generating $112.5 million in coal royalty revenues from our properties and our total revenue was $129.0 million. Most of our coal is produced by large companies, many of which are publicly traded, with professional and experienced sales departments. A significant portion of our coal is sold by our lessees under coal supply contracts that have terms of one year or more. However, over the long term, our coal royalty revenues are affected by changes in the market price of coal.
     Our revenue and profitability are dependent on our lessees’ ability to mine and sell our coal reserves. Generally, our lessees make payments to us based on the greater of a percentage of the gross sales price or a fixed price per ton of coal they sell, subject to minimum monthly, quarterly or annual payments. These minimum royalties are generally recoupable over a specified period of time (usually three to five years) if sufficient royalties are generated from coal production in future periods. We do not recognize these minimum coal royalties as revenue until the applicable recoupment period has expired without recoupment or they are recouped through production. Until recognized as revenue, these minimum royalties are recorded as deferred revenue, a liability on our balance sheet.
     As of December 31, 2005, approximately 57% of our reserves were low sulfur coal, including compliance coal, which constitutes approximately 35% of our total reserves. In 2005 and during 2006, we continued to diversify geographically by significantly expanding our presence in the high-sulfur regions of the Illinois Basin and Northern Appalachia, which we see as being the next regions that will experience increased coal production. We expect the Williamson Development property in Illinois to be one of our largest producing leases once it has reached full production, which we anticipate by late 2007. As utilities add scrubbers to existing power plants in response to more stringent environmental rules, and as new, more technologically advanced power plants are built, we expect to see an increased demand for mid- to high-sulfur coal. We believe that our recent acquisitions are an important step in our strategy to continue to diversify our assets, and that we are well-positioned to take advantage of future expansion opportunities in these regions.
     As a result of escalating coal prices over the last few years, we have received substantially higher royalties from our lessees, and our coal royalty revenue per ton has increased dramatically during that period. Over the past nine months, we have read reports that coal prices are softening and some have declined slightly following a mild winter and increased stockpiles at the utilities. To date, we have not seen these lower prices reflected in our financial results, largely because the bulk of our coal is sold by our lessees at previously contracted rates. We believe that although any weakness in pricing is temporary, in the near term prices will not return to the record high levels we have experienced over the last two years. As a result, we expect that our coal royalty revenue per ton will increase at a slower rate, if at all, over the next few years and that over the long-term a larger percentage of our future revenue growth will come from acquisitions of new reserves.
     For the nine months ended September 30, 2006, approximately 29% of our coal royalty revenues and 24% of the related production were from metallurgical coal, which was sold to steel companies in the eastern United States, South America, Europe and Asia. Prices of metallurgical coal have been substantially higher over the last two years and we expect them to remain at historically high levels for the remainder of 2006. Metallurgical coal, because of its unique chemical characteristics, is usually priced higher than steam coal. The current pricing environment for U.S. metallurgical coal is strong in both the domestic and export markets.

     In addition to coal royalty revenues, we generated approximately 5% and 2% of our revenues for the nine months ended September 30, 2006 and 2005, respectively, from rentals; timber; and wheelage payments, which are toll payments for the right to transport third-party coal over or through our property. These revenues are classified as “Other” revenues on our income statement and in 2006 include $2.6 million related to the sale of timber properties. The “Other” revenues also include revenues from coal preparation plants that we own and lease to third parties.
     In the third quarter, we entered into a memorandum of understanding with Sedgman USA, LLC under which we agreed to jointly identify and develop coal preparation plants. We will own the plants and lease them to Sedgman, who will operate the plants and pay us a monthly fee that will be the greater of a fixed price per ton or a percentage of the sales price of the coal, similar to our coal lease agreements. We have already acquired two facilities with Sedgman, and expect this arrangement to provide us with an additional platform for growth in the coal industry.
     Under our partnership agreement, we are required to distribute all of our available cash each quarter. Because distributable cash flow is a significant liquidity metric that is an indicator of our ability to generate cash flows at a level that can sustain or support an increase in quarterly cash distributions paid to our partners, we view it as the most critical measure of our success as a company. Distributable cash flow is also the quantitative standard used in the investment community with respect to publicly traded partnerships.
     Distributable cash flow represents cash flow from operations less actual principal payments and cash reserves set aside for scheduled principal payments on our senior notes. Although distributable cash flow is a “non-GAAP financial measure,” we believe it is a useful adjunct to net cash provided by operating activities under GAAP. Distributable cash flow is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing or financing activities. Distributable cash flow may not be calculated the same for NRP as for other companies. A reconciliation of distributable cash flow to net cash provided by operating activities is set forth below.

Acquisitions
     2006 Acquisitions
     Red Fox. On September 5, 2006, we closed the second acquisition under our memorandum of understanding with Sedgman USA, LLC for approximately $7.7 million, of which $3.0 million was paid at closing. The Red Fox preparation plant and coal handling facility is located near Bishop, West Virginia. The plant, which was completed in late October, will handle an estimated 20 million tons of coal reserves during its life. The initial $3.0 million payment paid at closing was funded through our credit facility. The remaining payments were funded with cash.
     Coal Mountain. On August 24, 2006, we closed the first acquisition under our memorandum of understanding with Sedgman USA, LLC for the Coal Mountain preparation plant, handling facility and rail load-out facility located near Baileysville, West Virginia. The preparation plant is still under construction, but the coal handling and rail load-out facility has been completed and is currently transloading coal. We expect that approximately 35 million tons of coal will be processed through this facility during its life. The total construction price for the facility will be $16.1 million, of which approximately $14.3 million was paid during the third

quarter. These payments were funded primarily through our credit facility. The preparation plant and related funding will be completed during the fourth quarter of 2006.
     Williamson Development. On January 20, 2006 and August 15, 2006, we closed the second and third phases of the Williamson Development acquisition for $35 million each. We funded the January 20, 2006 acquisition with proceeds from the issuance of senior notes and the August 15, 2006 acquisition with borrowings under our credit facility.
     Allegany County, Maryland. On June 29, 2006, we closed an acquisition for $5.5 million consisting of 3.3 million tons of coal in Allegany County, Maryland. We funded this acquisition with cash.
     James River. On May 26, 2006, we acquired 16.3 million tons of coal reserves and an overriding royalty interest on an additional 2.4 million tons for $10.85 million from James River Coal Company. These reserves are located in Pike, Warrick and Gibson Counties in Indiana. We funded this acquisition with cash.
     2005 Acquisitions
     AFG. On November 21, 2005, we completed the acquisition of 179 million tons of coal reserves in Ohio and Pennsylvania for $29 million.
     Area F/Lexington. In two separate transactions on September 26, 2005, we acquired approximately 25 million tons of owned coal reserves and an overriding royalty on approximately 14 million tons of leased coal reserves in Randolph, Upshur and Barbour Counties in north central West Virginia for $13.5 million.
     Dolphin. On September 22, 2005, we acquired a coal preparation plant and rail load-out facility in Greenbrier County, West Virginia for $6 million. The facilities will process coal produced primarily from our Plum Creek properties.
     Williamson Development. On June 1, 2005, we signed a definitive agreement to purchase interests in approximately 144 million tons in the Illinois Basin for $105 million in three separate transactions. On July 11, 2005, we closed the first of the three transactions for $35 million.
     Plum Creek. On March 3, 2005, we completed an acquisition of coal reserves from Plum Creek Timber Company, Inc. for $21.25 million. This property consists of approximately 85 million tons of coal reserves located on approximately 175,000 acres in Virginia, West Virginia and Kentucky with most of the reserves leased under 29 leases.
Disposition
     Virginia Timber Properties. For the nine months ended September 30, 2006, we received total proceeds of $4.8 million and recorded a total gain of $2.6 million related to transactions involving the sale of timber and related surface acreage located on our property in Wise and Dickenson Counties, Virginia. The final phase of this transaction is scheduled to close later in 2006.
Impact of Adoption of FAS 123R
     We adopted Statement of Financial Accounting Standards No. 123R “Share-Based Payment,” effective January 1, 2006 using the modified prospective approach. Prior to 2006, awards under our Long Term Incentive Plan have been accounted for on the intrinsic method under the provisions of APB No. 25. FAS 123R provides that grants must be accounted for using the fair value method, which requires us to estimate the fair value of the grant and charge the estimated fair value to expense over the service or vesting period of the grant. In addition, FAS 123R requires that we include estimated forfeitures in our periodic computation of the fair value of the liability and that the fair value be recalculated at each reporting date over the service or vesting period of the grant. FAS 123R required us to recognize the cumulative effect of the accounting change at the date of adoption based on the difference between the fair value of the unvested awards and the intrinsic value previously recorded. Included in operating costs and expenses was a one time charge of $661,000 which represents the cumulative effect of adopting FAS 123R as of January 1, 2006. This adjustment had the impact of reducing net income per limited partner unit for the nine month period ended September 30, 2006 by $0.02. Application of FAS 123R to prior periods did not materially impact amounts previously presented.

Three months ended September 30, 2006 compared with three months ended September 30, 2005
     Revenues. For the three months ended September 30, 2006, coal royalty revenues were $36.9 million on 12.8 million tons of coal produced, compared to $34.3 million in coal royalty revenues on 12.7 million tons of coal produced for the third quarter of 2005, representing a 8% increase in coal royalty revenues and a 1% increase in production. Coal royalty revenues comprised approximately 89% and 88% of our total revenue for each of the three month periods ended September 30, 2006 and 2005, while property taxes, minimums recognized as revenue, override royalties and other, comprised the remaining 11% and 12% of our total revenue for those periods.
     The following is a breakdown of our major coal producing regions:
     Appalachia. Coal royalty revenues in Appalachia for the quarter ended September 30, 2006 were $32.3 million compared to $31.2 million for the same period in 2005, an increase of $1.1 million or 3%. For the quarter ended September 30, 2006, production in Appalachia was 10.4 million tons compared to 10.6 million tons for the same period in 2005, a decrease of 0.2 million tons or 2%. The Appalachian results by region are set forth below.
     Northern Appalachia. Coal royalty revenues increased 4% from $2.2 million for the quarter ended September 30, 2005 to $2.3 million for the quarter ended September 30, 2006. Production for each of the periods was nearly constant at 1.2 million tons. The properties acquired with the AFG acquisition generated coal royalty revenues of $1.1 million and production of 0.6 million tons. The property acquired in our Allegany County, Maryland acquisition generated coal royalty revenues of $234,000 and production of 90,000 tons. In addition to the properties acquired in the above acquisitions, the following properties experienced significant variances.
    Sincell – production decreased from 615,000 tons to 101,000 tons and coal royalty revenues decreased from $937,000 to $178,000. The decreased tonnage was due to a greater proportion of production from the longwall unit being on adjacent property.
 
    Stony River – production decreased from 118,000 tons to zero tons and coal royalty revenues decreased from $313,000 to zero due to the lessee idling production during bankruptcy proceedings.
     Central Appalachia. Production from our Central Appalachia properties increased slightly for the quarter ended September 30, 2006 compared to the quarter ended September 30, 2005 from 7.8 million tons to 7.9 million tons, an increase of 1%. Due to generally higher sales prices, our coal royalty revenues from these properties increased 12% from $21.9 million to $24.6 million over those same periods. The results in Central Appalachia are a combination of increases and decreases over a number of properties, the most significant of which are described below.
    VICC/Kentucky Land — production increased from 530,000 tons to 860,000 tons and coal royalty revenues increased from $1.7 million to $2.9 million. The increased production was due to an increase in tonnage from mines moving onto the property that more than offset mines moving off the property
 
    Alpha/VICC — production increased from 1.6 million tons to 1.8 million tons and coal royalty revenues increased from $4.3 million to $5.3 million. The increased revenue was due to improved production from mines on the property and higher sales prices being realized by our lessees.
 
    Plum Creek properties — production increased from 165,000 tons to 421,000 tons and coal royalty revenues increased from $462,000 to $1.5 million. The increased production was due primarily to mines in West Virginia increasing production from their start up levels in the previous year on the properties.
 
    Pinnacle — production decreased from 807,000 tons to 582,000 tons and coal royalty revenues decreased from $2.8 million to $1.7 million. The decreased tonnage was due to a greater proportion of production from the mines being on adjacent property.

     Southern Appalachia. Our coal royalty revenues in Southern Appalachia decreased 23% from $7.1 million for the quarter ended September 30, 2005 to $5.5 million for the quarter ended September 30, 2006, as production decreased 16% from 1.7 million tons to 1.4 million tons over those same periods. The following properties contributed to these results.
    Twin Pines/Drummond — production decreased from 233,000 tons to 159,000 tons and coal royalty revenues decreased from $2.1 million to $992,000. This decrease was partially due to one mine being temporarily idled during the quarter and lower per ton royalty being paid by the lessee under the terms of the lease on another mine.
 
    BLC Properties — production decreased from 1.0 million tons to 875,000 tons and coal royalty revenues decreased from $3.4 to $3.1 million. The decrease was due to slightly reduced production and some temporary royalty reduction to one lessee to encourage mining in some areas of difficult geology and another lessee having more of its production on adjacent property.
 
    Oak Grove — production decreased from 420,000 tons to 361,000 tons and coal royalty revenues decreased from $1.6 million to $1.4 million. The decreases were due to slightly lower production from the mine.
     Illinois Basin. Production in the Illinois Basin decreased 0.2 million tons or 41% from 0.6 million tons for the quarter ended September 30, 2005 to 0.4 million tons for the quarter ended September 30, 2006 and coal royalty revenues decreased $0.2 million or 15% from $1.0 million for the quarter ended September 30, 2005 to $0.8 million for the quarter ended September 30, 2006. The following properties experienced significant variances.
    Hocking Wolford/Cummings — production decreased from 295,000 tons to 5,000 tons and coal royalty revenues decreased from $388,000 to $7,000. The decreases were due to production moving to adjacent property.
 
    Sato/Trico — production increased from 329,000 tons to 363,000 tons and coal royalty revenues increased from $568,000 to $801,000. The increases were due to a slight increase in production from the mine and higher sales price received by our lessee.
     Northern Powder River Basin. Production from our Western Energy property increased 0.6 million tons or 43% from 1.4 million tons to 2.0 million tons and coal royalty revenues increased $1.7 million or 81% from $2.1 million to $3.8 million. These increases were due to the typical variations in production resulting from the checkerboard ownership pattern and additional royalty revenue due to a positive price adjustment received by a lessee during the third quarter.
     Operating costs and expenses. For the quarter ended September 30, 2006, total expenses were $12.9 million, compared to $14.8 million for the third quarter of 2005, representing a decrease of $1.9 million, or 13%. Included in total expenses are:
    Depletion and amortization of $7.0 million for the quarter ended September 30, 2006 compared to $8.2 million for the same period in 2005. Fluctuations in depletion are dependent on the depletion rates where coal is mined which can cause total depletion to be lower in periods where production is actually up;
 
    General and administrative expenses for the third quarter of 2006 were approximately the same when compared to the same period for 2005; and
 
    Property, franchise and other taxes were $2.1 million for the third quarter of 2006, compared to $2.0 million for the third quarter of 2005, an increase of $0.1 million, or 5%, due to an increase in franchise taxes for 2006, as well as taxes on additional properties acquired since last year.
     Interest Expense. For the quarter ended September 30, 2006, interest expense was $4.0 million compared to $2.9 million for 2005, an increase of $1.1 million. This increase is attributed to additional borrowings on our senior notes during the third quarter of 2005 and the first quarter of 2006, as well as larger outstanding balances on our credit facility.

Nine months ended September 30, 2006 compared with nine months ended September 30, 2005
     Revenues. For the nine months ended September 30, 2006, coal royalty revenues were $112.5 million on 40.2 million tons of coal produced, compared to $104.8 million in coal royalty revenues on 39.6 million tons of coal produced for the nine months ended September 30, 2005, representing a 7% increase in coal royalty revenues and a 2% increase in production. Coal royalty revenues comprised approximately 87% and 90% of our total revenue for each of the nine month periods ended September 30, 2006 and 2005, while property taxes, minimums recognized as revenue, override royalties and other, comprised the remaining 13% and 10% of our total revenue for those periods.
     The following is a breakdown of our major coal producing regions:
     Appalachia. As a result of higher prices in the Central Appalachia region, coal royalty revenues in Appalachia for the nine months ended September 30, 2006 were $99.4 million compared to $95.2 million for the same period in 2005, an increase of $4.2 million or 4%. For the nine months ended September 30, 2006, production in Appalachia was 32.7 million tons compared to 33.2 million tons for the same period in 2005, a decrease of 0.5 million tons or 2%. The Appalachian results by region are set forth below.
          Northern Appalachia. Primarily as a result of the acquisition of the AFG properties in 2005 and the Allegany County, Maryland property in 2006, our coal royalty revenues increased 22% from $6.8 million for the nine months ended September 30, 2005 to $8.3 million for the nine months ended September 30, 2006. Production increased 22% from 3.6 million tons to 4.4 million tons over the same periods. The properties acquired with the AFG acquisition generated coal royalty revenues of $4.7 million and production of 2.6 million tons and the Allegany County, Maryland property generated coal royalty revenues of $234,000 and production of 90,000 tons. These increases were partially offset by the following significant decreases.
    Sincell — production decreased from 2.1 million tons to 594,000 tons and coal royalty revenues decreased from $3.6 million to $992,000. The decreased tonnage was due to a greater proportion of production from the longwall unit being on adjacent property.
 
    Stony River — production decreased from 326,000 tons to 17,000 tons and coal royalty revenues decreased from $777,000 to $55,000 due to the lessee idling production during bankruptcy proceedings.
          Central Appalachia. Production from our Central Appalachia properties decreased 4% from 25.0 million tons for the nine months ended September 30, 2005 to 24.0 million tons for the nine months ended September 30, 2006. However, as a result of higher prices our coal royalty revenues from these properties increased 7% from $70.0 million to $75.0 million over those same periods. The results in Central Appalachia are a combination of increases and decreases over a number of properties, the most significant of which are described below.
    VICC/Kentucky Land — production increased from 1.8 million tons to 2.7 million tons and coal royalty revenues increased from $5.9 million to $9.4 million. The increased production was due to an increase in tonnage from mines moving onto the property that more than offset mines moving off the property.
 
    Lynch — production increased from 3.8 million tons to 3.9 million tons and coal royalty revenues increased from $8.5 million to $10.1 million.
 
    VICC/Alpha — production increased from 4.9 million tons to 5.0 million tons and coal royalty revenues increased from $12.8 million to $15.0 million.
 
    Kingston — production increased from 1.2 million tons to 1.4 million tons and coal royalty revenues increased from $3.3 million to $4.3 million. The increased tonnage was due to additional producing units being on our property and a new surface mine increasing production.
 
    Plum Creek properties — production increased from 418,000 tons to 1.1 million tons and coal royalty revenues increased from $1.2 million to $3.4 million. The increased production and coal royalty revenues were due primarily to new mines in West Virginia increasing production on the properties over their earlier startup levels.

18


Table of Contents

    Pinnacle — production decreased from 2.2 million tons to 1.8 million tons and coal royalty revenues decreased from $8.1 million to $6.0 million. The decreases were primarily due to a greater proportion of production from the mines being on adjacent property and slightly lower prices being received by our lessee.
 
    Eunice — production decreased from 2.2 million tons to 633,000 tons and coal royalty revenues decreased from $5.4 million to $2.2 million due to a greater proportion of production from both the longwall mine and the surface mine coming from adjacent property.
 
    Eastern Kentucky Property— production decreased from 493,000 tons to 42,000 tons and coal royalty revenues decreased from $1.7 million to $186,000. The decreased production was due to the lessee temporarily idling the operation. We are currently working with the lessee and a possible replacement operator to resume production.
          Southern Appalachia. Our coal royalty revenues in Southern Appalachia decreased 15% from $18.5 million for the nine months ended September 30, 2005 to $16.1 million for the nine months ended September 30, 2006, as production decreased 9% from 4.7 million tons to 4.3 million tons over the same period. The following properties contributed to this decrease.
    Twin Pines/Drummond — production increased from 475,000 tons to 480,000 tons and coal royalty revenues decreased from $4.1 million to $2.8 million. The decrease in coal royalty revenues was partially due to a temporary royalty reduction in the first half of the year and a lower per ton royalty being paid under the terms of the lease at one mine, as well as a temporary idling of another mine.
 
    BLC Properties — production decreased from 2.9 million tons to 2.7 million tons and coal royalty revenues decreased from $9.9 million to $9.1 million. The decrease was due to slightly reduced production and some temporary royalty reduction to one lessee to encourage mining in some areas of difficult geology.
 
    Oak Grove — production decreased from 1.2 million tons to 1.0 million tons and coal royalty revenues decreased from $4.5 million to $4.2 million. The decreases were due to slightly lower production from the mine.
     Illinois Basin. Production in the Illinois Basin increased 14% from 2.2 million tons for the nine months ended September 30, 2005 to 2.5 million tons for the nine months ended September 30, 2006 and coal royalty revenues increased 33% from $3.4 million for the nine months ended June 30, 2005 to $4.5 million for the nine months ended September 30, 2006. The following properties experienced significant variances.
    Hocking Wolford/Cummings — production increased from 1.1 million tons to 1.4 million tons and coal royalty revenues increased from $1.5 million to $2.2 million. The increased tonnage was due to a greater proportion of the production being on our property and higher sales prices received by our lessee.
 
    Sato/Trico — production remained nearly constant at 1.1 million tons and coal royalty revenues increased from $1.8 million to $2.3 million. The increase in coal royalty revenues was due to higher sales prices received by our lessee.
     Northern Powder River Basin. Production from our Western Energy property increased 0.9 million tons or 22% from 4.1 million tons to 5.0 million tons and coal royalty revenues increased $2.5 million or 40% from $6.2 million to $8.7 million. These increases were due to the typical variations in production resulting from the checkerboard ownership pattern and additional royalty revenues attributable to a positive price adjustment received by a lessee during the third quarter.
     Other revenues. Included in other revenues are two related sales of timber and related surface acreage located on our property in Wise and Dickenson Counties, Virginia. We received proceeds from the sales of $4.8 million, resulting in a gain of $2.6 million. A final related sale in the amount of approximately $1.5 million to $2.0 million is expected to close in the fourth quarter of 2006.
     Operating costs and expenses. For the nine months ended September 30, 2006, total expenses were $40.8 million, compared to $42.8 million for the first nine months of 2005, representing a decrease of $2.0 million, or 5%. Included in total expenses are:
    Depletion and amortization of $22.1 million for the nine months ended September 30, 2006 compared to $24.7 million for the same period in 2005, representing a decrease of $2.6 million. Fluctuations in depletion are dependent on the depletion rates where coal is mined which can cause total depletion to be lower in periods where production is actually up;

Table of Contents

    General and administrative expenses of $11.0 million for the first three quarters of 2006, compared to $10.0 million for the nine months ended September 30, 2005, an increase of $1.0 million, or 10%. The increase in general and administrative expenses is attributable to additional expenses required to manage a larger portfolio of properties as well as an increase in incentive compensation accrual partially attributable to the adoption of FAS 123R; and
 
    Property, franchise and other taxes of $6.5 million for the first nine months of 2006, compared to $5.7 million for the same period of 2005, an increase of $0.8 million, or 14%, due to an increase in franchise taxes for 2006, as well as taxes on additional properties acquired since last year.
     Interest Expense. For the nine months ended September 30, 2006, interest expense was $11.3 million compared to $7.9 million for 2005, an increase of $3.4 million. This increase is attributed to the additional issuance of senior notes during the third quarter of 2005 and the first quarter of 2006, as well as higher outstanding balances on our credit facility.
Related Party Transactions
Partnership Agreement
     Our general partner does not receive any management fee or other compensation for its management of Natural Resource Partners L.P. However, in accordance with our partnership agreement, our general partner and its affiliates are reimbursed for expenses incurred on our behalf. All direct general and administrative expenses are charged to us as incurred. We also reimburse indirect general and administrative costs, including certain legal, accounting, treasury, information technology, insurance, administration of employee benefits and other corporate services incurred by our general partner and its affiliates. Reimbursements to affiliates of our general partner may be substantial and will reduce our cash available for distribution to unitholders. The reimbursements to affiliates of our general partner for services performed by Western Pocahontas Properties and Quintana Minerals Corporation totaled $1.0 million and $0.8 million for the three month periods ended September 30, 2006 and 2005, respectively, and $3.0 million and $2.5 million for the nine month periods ended September 30, 2006 and 2005, respectively.
Liquidity and Capital Resources
Cash Flows and Capital Expenditures
     We satisfy our working capital requirements with cash generated from operations. Since our initial public offering, we have financed our property acquisitions through borrowings under our revolving credit facility, the issuance of our senior notes and the issuance of additional common units and cash. We believe that cash generated from our operations, combined with the availability under our credit facility and the proceeds from the issuance of debt and equity, will be sufficient to fund working capital, capital expenditures and future acquisitions. Our ability to satisfy debt service obligations, fund planned capital expenditures, make acquisitions and pay distributions to our unitholders will depend upon our ability to access the capital markets, as well as our future operating performance, which will be affected by prevailing economic conditions in the coal industry and financial, business and other factors, some of which are beyond our control. For a more complete discussion of factors that will affect the amount of cash we generate from our operations, please read “Item 1A – Risk Factors” in this Form 10-Q and our Form 10-K for the year ended December 31, 2005. Our capital expenditures, other than for acquisitions, have historically been minimal.
     Net cash provided by operations for the nine months ended September 30, 2006 and 2005 was $102.5 million and $91.9 million, respectively. Substantially all of our cash provided by operations is generated from coal royalty revenues.
     Net cash used in investing activities for the nine months ended September 30, 2006 was $101.1 million compared to $76.1 million for the same period in 2005. The 2006 results include the funding of the second and third phase of the Williamson Development acquisition for $70 million, the James River acquisition for $10.85 million, the Allegany County acquisition for $5.5 million, the Red Fox preparation plant and loadout for $5.2 million and the Coal Mountain preparation plant and loadout for $14.3 million. These acquisitions were partially offset by the proceeds from the sale of our Virginia timber assets and related surface tracts for $4.8 million. The 2005 results include the acquisition of coal reserves from Plum Creek Timber Company, Inc. for $21.3 million, Williamson Development phase one for $35 million, Dolphin preparation plant and loadout for $6.0 million and the acquisition of the Area F/Lexington coal reserves for $13.5 million.

Table of Contents

     Net cash provided by financing activities for the nine months ended September 30, 2006 was $11.6 million compared to $8.4 million used for financing for the same period a year ago. In the nine months ended September 30, 2006, we issued $50.0 million of 5.05% senior notes to fund the second phase of the Williamson Development acquisition for $35 million and repaid $15 million on our credit facility. We also made our annual principal payment of $9.35 million on our senior notes. In addition, we borrowed $53 million on our credit facility to fund acquisitions made during the year as well as funding the final phase of the Williamson Development acquisition. In the nine months ended September 30, 2005, we borrowed $56.0 million on our revolving credit facility to fund acquisitions and subsequently repaid $50.0 million of the revolving credit facility with the issuance of $50.0 million in new 5.05% senior notes. In addition to the repayment of the revolving credit facility, we paid $9.35 million in principal payments on our senior notes. We also paid distributions to our partners of $67.0 million in the first half of 2006 compared to $55.1 million for the same period in 2005.
Contractual Obligations and Commercial Commitments
     At September 30, 2006, our debt consisted of:
    $63 million outstanding under our $175 million revolving credit facility that matures in October 2010;
 
    $50.1 million of 5.55% senior notes due 2023;
 
    $61.85 million of 4.91% senior notes due 2018;
 
    $35 million of 5.55% senior notes due 2013; and
 
    $100 million of 5.05% senior notes due 2020.
     Credit Facility. Our $175 million revolving credit facility expires in 2010. We have the option to increase the limit up to $300 million at any time during the term of the facility. Our obligations under the credit facility are unsecured but are guaranteed by our operating subsidiaries. We may prepay all loans at any time without penalty. Indebtedness under the revolving credit facility bears interest, at our option, at either:
    the higher of the federal funds rate plus an applicable margin ranging from 0% to 1.00% or the prime rate as announced by the agent bank; or
    at a rate equal to LIBOR plus an applicable margin ranging from .75% to 2.00%.
     We incur a commitment fee on the unused portion of the revolving credit facility at a rate ranging from 0.15% to 0.40% per annum.
     The credit agreement contains covenants requiring us to maintain:
    a ratio of consolidated indebtedness to consolidated EBITDDA (as defined in the credit agreement) of 3.75 to 1.0 for the four most recent quarters; provided however, if during one of those quarters we have made an acquisition, then the ratio shall not exceed 4.0 to 1.0 for the quarter in which the acquisition occurred and (1) if the acquisition is in the first half of the quarter, the next two quarters or (2) if the acquisition is in the second half of the quarter, the next three quarters; and
    a ratio of consolidated EBITDDA to consolidated fixed charges (consisting of consolidated interest expense and consolidated lease operating expense) of 4.0 to 1.0 for the four most recent quarters.
     Senior Notes. NRP Operating LLC issued the senior notes under a note purchase agreement. The senior notes are unsecured but are guaranteed by our operating subsidiaries. We may prepay the senior notes at any time together with a make-whole amount (as defined in the note purchase agreement). If any event of default exists under the note purchase agreement, the noteholders will be able to accelerate the maturity of the senior notes and exercise other rights and remedies.
     The note purchase agreement contains covenants requiring our operating subsidiary to:
    not permit debt secured by certain liens and debt of subsidiaries to exceed 10% of consolidated net tangible assets (as defined in the note purchase agreement); and
    maintain the ratio of consolidated EBITDA to consolidated fixed charges (consisting of consolidated interest expense and consolidated operating lease expense) at not less than 3.5 to 1.0.

(1)   The amounts indicated in the table include principal and interest due on our senior notes.
Shelf Registration Statement
     On December 23, 2003, we and our operating subsidiaries jointly filed a $500 million “universal shelf” registration statement with the Securities and Exchange Commission for the proposed sale of debt and equity securities. Securities issued under this registration statement may be in the form of common units representing limited partner interests in Natural Resource Partners or debt securities of NRP or any of our operating subsidiaries. The registration statement also covers, for possible future sales, up to 673,715 common units held by Great Northern Properties Limited Partnership. In November 2004, Great Northern Properties sold 300,000 common units in a private placement. We did not and will not receive any proceeds from the sale of common units by Great Northern Properties.
     Approximately $290.2 million is available under our shelf registration statement. The securities may be offered from time to time directly or through underwriters at amounts, prices, interest rates and other terms to be determined at the time of any offering. The net proceeds from the sale of securities from the shelf will be used for future acquisitions and other general corporate purposes, including the retirement of existing debt.
Off-Balance Sheet Transactions
     We do not have any off-balance sheet arrangements with unconsolidated entities or related parties and accordingly, there are no off-balance sheet risks to our liquidity and capital resources from unconsolidated entities.
Inflation
     Inflation in the United States has been relatively low in recent years and did not have a material impact on operations for the first nine months of 2006 or 2005.
Environmental
     The operations our lessees conduct on our properties are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted. As an owner of surface interests in some properties, we may be liable for certain environmental conditions occurring at the surface properties. The terms of substantially all of our coal leases require the lessee to comply with all applicable laws and regulations, including environmental laws and regulations. Lessees post reclamation bonds assuring that reclamation will be completed as required by the relevant permit, and substantially all of the leases require the lessee to indemnify us against, among other things, environmental liabilities. Some of these indemnifications survive the termination of the lease. Because we have no employees, employees of Western Pocahontas Properties Limited Partnership make regular visits to the mines to ensure compliance with lease terms, but the duty to comply with all regulations rests with the lessees. We believe that our lessees will be able to comply with existing regulations and do not expect any lessee’s failure to comply with environmental laws and regulations to have a material impact on our financial condition or results of operations. We have neither incurred, nor are aware of, any material environmental charges imposed on us related to our properties as of September 30, 2006. We are not associated with any environmental contamination that may require remediation costs. However, our lessees regularly conduct reclamation work on the properties under lease to them. Because we are not the permittee of the operations on our property, we are not responsible for the costs associated with these operations. In addition, West Virginia has established a fund to satisfy any shortfall in our lessees’ reclamation obligations.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
     We are exposed to market risk, which includes adverse changes in commodity prices and interest rates as discussed below:
Commodity Price Risk
     We are dependent upon the effective marketing and efficient mining of our coal reserves by our lessees. Our lessees sell coal under various long-term and short-term contracts as well as on the spot market. A large portion of these sales are under long-term contracts. The coal industry in Appalachia is experiencing an increase in both domestic and foreign demand, as well as a shortage of supply. As a result, the current price of coal in Appalachia is at historically high levels. If this price level is not sustained or our lessees’ costs increase, some of our coal could become uneconomic to mine, which would adversely affect our coal royalty revenues. In addition, the current prices may make coal from other regions more economical and may make other competing fuels relatively less costly than Appalachian coal.
Interest Rate Risk
     Our exposure to changes in interest rates results from our borrowings under our revolving credit facility, which may be subject to variable interest rates based upon LIBOR. At September 30, 2006, we had outstanding $63.0 million in variable interest rate debt. If LIBOR rates were to increase by 100 basis points, annual interest expense would increase by $630,000, assuming the same principal amount remained outstanding over the next twelve months.
Item 4. Controls and Procedures
     NRP carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act) as of the end of the period covered by this report. This evaluation was performed under the supervision and with the participation of NRP management, including the Chief Executive Officer and Chief Financial Officer of the general partner of the general partner of NRP. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures are effective in producing the timely recording, processing, summarizing and reporting of information and in accumulating and communicating information to management as appropriate to allow for timely decisions with regard to required disclosure.
     No changes were made to our internal control over financial reporting during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
