Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§ 230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§ 240.12b-2 of this chapter).

On January 19, 2018, the San Juan Basin Royalty Trust (the “Trust”) issued a press release, a copy of which is attached hereto as Exhibit 99.1, announcing a monthly cash distribution to the holders of its units of beneficial interest of $3,115,522.27 or $0.066844 per unit, based principally upon estimated production during the month of November 2017, as further described below. The distribution is payable February 14, 2018, to unit holders of record as of January 31, 2018.

The sale of San Juan Basin assets, including the oil and gas interests from which the Trust’s royalty interest was carved (“Subject Interests”), from Burlington Resources Oil & Gas Company LP (“Burlington”) to Hilcorp San Juan L.P. (“Hilcorp”) closed on July 31, 2017. Due to the transition from Burlington, Hilcorp informed the Trust that Hilcorp does not yet have all of the revenue decks for November 2017 installed, and therefore does not have the appropriate detail to provide actual revenue numbers for the January 2018 distribution. Therefore, Hilcorp estimated the January 2018 revenue distribution based on the revenue distribution detail for the July 2017 production month previously provided by Burlington and rounded to the nearest thousand.

The January 2018 declaration of cash distribution includes an additional $1.0 million in estimated gross revenue based on Hilcorp’s knowledge that production volumes in November 2017 were in line with production volumes during the previous month.

In accordance with general instruction B.2 to Form 8-K, the information in this Form 8-K shall be deemed “furnished” and not “filed” with the Securities and Exchange Commission for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise, subject to the liabilities of that section.
