This is the third case in today’s suspense money trilogy; here, as in Phillips Petroleum Co. v. Adams, 5 Cir. 1975,
From June 26, 1955, until September 30, 1970, Phillips took casinghead gas from lands belonging to the various claimants here, and situated in Hutchinson County, Texas. These purchases were made according to several percentage-of-proceeds sales contracts, and, as in
Adams
and
First National Bank,
Phillips made monthly payments to the holders of the particular mineral estates on the basis of the “firm proceeds” of its sales to third parties. Phillips withheld payment of the suspense money which it collected pending Federal Power Com

mission approval of the higher rates which the pipeline company actually charged its own customers throughout the period of the disputed sales. The mineral rights to the two tracts of land involved in this case changed hands so often during this fifteen-year period, that we will not attempt to trace all of those transactions. Suffice it to say that the assignments were of the sort in controversy in
Adams
and
First National Bank,
and that after the FPC’s Hugoton-Andarko Rate Case, Op: 586, 44 F.P.C. 761, aff’d, 9 Cir. 1972,
Before this ease went to trial, the several claimants, assignors and assignees alike, adopted the salutary course of resolving their disagreements with respect to the principal sum of the suspense money, in settlement agreements dated June 1, 1973, and January 31, 1974, so that neither the district court nor this court has been forced to unravel the various entitlements to the principal sum. The only question submitted to the district court was whether Phillips should pay interest on the suspense money for the fifteen years in which the pipeline company enjoyed the use of the money; for the reasons set out at length in Adams, we conclude that the law of Texas permits the award of interest here, and that equitable considerations require such an award. This case differs from Adams and First National Bank in that both assignors and assignees here demand interest, and in that all these claimants ask for interest for the entire period in which Phillips held and used the principal sum to which they are now entitled. Another distinguishing feature of this case is that the claimants have agreed on the division of interést in the settlement agreements referred to above. We now remand this case to the district court for a determination of the amount of interest which Phillips must pay to each of the various claimants, consistent with Adams and the' settlement agreements. For the reasons stated in Adams, Phillips need not pay interest for the period subsequent to March 12, 1973, the date of its unconditional tender of the principal sum into court.
Reversed and remanded.
