3 The 2012 divestiture of District 5 (West Texas) affected this number. District 5 applied water flood techniques that utilized all produced water (recycled/reused water) from active wells.

4 1,466 barrels of this total volume can be attributed to acts of vandalism in Colorado, which were reported to authorities.

5 Emissions for 2014 divestitures reported through effective date of divestiture. Emissions for divested operations in prior years reported through closing date of divestiture.

6 Limited existing infrastructure related to our operations in Equatorial Guinea and “stranded” wells in the DJ Basin were the primary contributors to an increase in flaring in 2013 compared to 2012.

7 To be consistent with the rest of our international greenhouse gas calculations, we applied the industry recognized American Petroleum Institute (API) Compendium calculation to our Equatorial Guinea operations.

8 Reductions reflect process improvements that allowed more accurate tracking of these metrics.
