b'The projection should not be interpreted as representing the current value to Kosmos. Materialrevisions to estimates of proved reserves may occur in the future; development and production of thereserves may not occur in the periods assumed; actual prices realized are expected to vary significantlyfrom those used; and actual costs may vary. Kosmos investment and operating decisions are not basedon the information presented, but on a wide range of reserve estimates that include probable as well asproved reserves and on a wide range of different price and cost assumptions.The standardized measure is intended to provide a better means to compare the value of Kosmosproved reserves at a given time with those of other oil producing companies than is provided bycomparing raw proved reserve quantities.Equity MethodInvestmentU.S. Gulf of EquatorialGhana Mexico Guinea Total(In millions)At December 31, 2018Future cash inflows . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 5,882 $2,951 $1,735 $10,568Future production costs . . . . . . . . . . . . . . . . . . . . . . . .
