San Juan Basin Royalty Trust Supplements Prior Release Concerning Monthly Cash Distribution

Compass Bank (the "Trustee") as Trustee of the San Juan Basin Royalty Trust (NYSE:SJT) (the "Trust"), today announced that it has received additional information from Burlington Resources Oil & Gas Company LP ("Burlington") regarding the content of the Trust’s news release issued on November 18, 2013.

For the months of April 2013 to October 2013, Burlington caused production volumes to be overstated by a total of 1,314,555 Mcf (1,608,598 MMBtu) due to a workpaper formulation error. The November distribution reflects a volume adjustment to correct the overstated production volumes. Burlington indicated this was a volume-only adjustment which did not impact the distribution amount. However, it did affect the volumes reported and therefore, the calculation of the average price per Mcf and MMBtu. Following the downward adjustment, the gas production volumes reported in November 2013 totaled 1,345,023 Mcf (1,300,953 MMBtu.)

The average monthly gas price Burlington reports to the Trust is a calculated price. It is determined by dividing gross monthly revenue by production volume, and it does not represent an average of actual sales prices. Because the production volume number used in the calculation reported in November was reduced by 1,314,555 Mcf, the resulting average sales price calculated to an inordinately high $7.62 per Mcf ($7.88 per MMBtu).

Burlington’s summary of the reported volumes and prices, as corrected, is as follows:

Burlington indicates it has implemented additional procedures to their process to eliminate the possibility of a similar error occurring in the future. The Trust’s external compliance auditors have been consulted and will be reviewing Burlington’s revised calculations on behalf of the Trust.

Capital drilling costs reported in November 2013 were $-150,882. Burlington stated that the negative capital cost number is the result of an adjustment due to an error in capital cost allocation for a specific well. The entire cost of the well was included in calculating royalty income distributed to the Trust, but 25% should have been charged to others. The Trust received a credit to capital costs to correct that error, which credit exceeded the other capital costs properly charged to the Trust for the month.
