The principal asset of the Trust is a 75% net overriding royalty interest (the “Royalty”). The Royalty is similar to a net profits interest and it burdens certain of Southland’s oil and gas leasehold interests (the “Underlying Properties”) in properties located in the San Juan Basin of northwestern New Mexico. References below to “gross” wells and acres are to the interests of all persons owning interests therein, while references to “net” are to the interests of Burlington (from which the Royalty was carved) in such wells and acres.

The Underlying Properties consist of working interests, royalty interests, overriding royalty interests and other contractual rights in 151,900 gross (119,000 net) producing acres in San Juan, Rio Arriba and Sandoval Counties of northwestern New Mexico and 4,007 gross (1,156.70 net) wells, calculated on a well bore basis and not including multiple completions as separate wells. Of those wells, 7 gross (5 net) are oil wells and the balance are gas wells. Burlington reports that approximately 852 gross (325.19 net) of the wells are multiple completion wells resulting in a total of 4,859 gross (1,481.89 net) completions.

Production from conventional gas wells is primarily from the Pictured Cliffs, Mesaverde and Dakota formations, ranging in depth from 1,500 to 8,000 feet. During 1988, Southland began development of coal seam reserves in the Fruitland Coal formation. In 2011, Burlington drilled a conventional well, which was completed not only to the Mesaverde and the Dakota formations, but also to the Mancos Shale

formation, which lies between the two. In 2012 and 2013 Burlington drilled two horizontal wells in the Mancos Shale formation, one of which was completed on lands burdened by the Royalty. While Burlington will continue to assess its program of horizontal drilling, it expects no new horizontal or vertical drilling activity in the San Juan Basin in 2014.

The characteristics of the Pictured Cliffs, the Mesaverde and the Dakota reservoirs result in the wells having very long productive lives. A production index for oil and gas properties is derived by dividing remaining reserves by current production. Based upon the reserve report prepared by the Trust’s independent petroleum engineers as of December 31, 2013, the production index for the Underlying Properties is estimated to be approximately 10.32 years. The production index is subject to change from year to year based on reserve revisions and production levels and is not presented as an estimate of the life expectancy of the Trust. Among the factors considered by engineers in estimating remaining reserves of natural gas is the applicable sales price for gas. As the sales price increases, the producer can justify expending higher lifting costs and therefore reasonably expect to recover more of the known reserves. Accordingly, as gas prices rise, the production index increases and vice versa.

In addition to gas from conventional wells, the Underlying Properties also produce gas from coal seam wells completed to the Fruitland Coal formation. The process of removing coal seam gas is often

referred to as degasification or desorption. Millions of years ago, natural gas was generated in the process of coal formation and absorbed into the coal. Water later filled the natural fracture system. When the water is removed from the natural fracture system, reservoir pressure is lowered and the gas desorbs from the coal. The desorbed gas then flows through the fracture system and is produced at the well bore. The volume of formation water production typically declines with time and the gas production may increase for a period of time before starting to decline. In order to dispose of the formation water, surface facilities including pumping units are required. The price of coal seam gas is typically lower than the price of conventional gas. This is because the heating value of coal seam gas is much lower than that of conventional gas due to (a) ever increasing percentages of carbon dioxide in coal seam gas (carbon dioxide has no heating value), and (b) the absence of heavier hydrocarbons such as ethanes, propanes, and butanes, which are present in conventional gas. Furthermore, the processing fees for coal seam gas are typically higher than the processing fees for conventional gas due to the cost of extracting the carbon dioxide.

In February 2002, Burlington informed the Trust that the New Mexico Oil Conservation Division (the “OCD”) had approved plans for 80-acre infill drilling of the Dakota formation in the San Juan Basin. In July 2003, the OCD approved 160-acre spacing in the Fruitland Coal formation. Eighty-acre spacing has been permitted in the Mesaverde formation since

1997. The OCD has approved 320-acre spacing units for wells completed to the Mancos Shale within the Basin Mancos Gas Pool. For wells drilled horizontally, multiple units may be combined along the well bore so long as that well bore is perforated in each such unit.

In light of the challenged price environment for natural gas and natural gas liquids, Burlington plans to continue the temporary suspension of its drilling program in the San Juan Basin, indicating that it currently plans to have no drilling rigs operating in the Basin during 2014. However, Burlington reported that it continually monitors natural gas prices and plans to restart the program at some point in the future, dependent upon such gas prices. Existing wells will continue to be operated.

The Federal Energy Regulatory Commission is primarily responsible for federal regulation of natural gas. For a further discussion of gas pricing, gas purchasers, gas production and regulatory matters affecting gas production see Item 2, “Properties,” in the accompanying Form 10-K.

We are pleased to present the 2013 Annual Report of the San Juan Basin Royalty Trust. The report includes a copy of the Trust’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “Commission”) for the year ended December 31, 2013, without exhibits. The Form 10-K contains important information concerning the Underlying Properties, as defined below, including the oil and gas reserves attributable to the 75% net overriding royalty interest owned by the Trust. Production figures provided in this letter and in the Trustee’s Discussion and Analysis are based on information provided by Burlington Resources Oil & Gas Company LP (“Burlington”), the current owner of the Underlying Properties and the successor, through a series of assignments and mergers, to Southland Royalty Company (“Southland”). The Trust was established in November 1980 by Southland. Pursuant to the Indenture that governs the operations of the Trust, Southland conveyed to the Trust a 75% net overriding royalty interest (similar to a net profits interest) (the “Royalty”), carved out of Southland’s oil and gas leasehold interests (the “Underlying Properties”) in properties in the San Juan Basin of northwestern New Mexico.

The Royalty constitutes the principal asset of the Trust. Under the Indenture governing the Trust, the function of Compass Bank, as Trustee, is to collect the net proceeds attributable to the Royalty (“Royalty Income”), to pay all expenses and charges of the Trust, and then distribute the remaining available income to the Unit Holders. Income distributed to Unit Holders in 2013 was $36,492,592 or $0.782955 per Unit.

Distributable income for 2013 consisted of Royalty Income of $38,042,603 plus interest income of $3,413, less administrative expenses of $1,523,906 and an increase in cash reserves of $29,518. Information about the Trust’s estimated proved reserves of gas, including coal seam gas, and of oil as well as the present value of net revenues discounted at 10% can be found in Item 2, “Properties,” in the accompanying Form 10-K.

Certain Royalty Income is generally considered portfolio income under the passive loss rules of the Internal Revenue Code of 1986, as amended. Therefore, Unit Holders should generally not consider the taxable income from the Trust to be passive income in determining net passive income or loss. Unit Holders should consult their tax advisors for further information. Unit Holders of record will receive an annual individualized tax information letter and Forms 1099 for the year ending December 31, 2013. Unit Holders owning Units in nominee name may obtain monthly tax information from the Trust’s Web site or from the Trustee upon request. For the reader’s convenience, a glossary of definitions used in this report can be found on the inside back cover.
