   OPINION OF THE COURT

NYGAARD, Circuit Judge.

I.

DVI Financial Services (DVI) agreed to provide medical equipment and financing to Bay Area Regional Cancer Center and its founders (collectively Bay Area) for construction of the center and its initial operations. The parties executed a Master Equipment Lease Agreement, a Loan and Security Agreement and repayment schedules. In addition, Bay Area’s founders signed unconditional guarantees to back its obligations.

Bay Area faltered financially, and the parties restructured the arrangement twice. After Bay Area defaulted for a third time, DVI filed a breach of contract action against Bay Area and its guarantors in the Bucks County Court of Common Pleas. Bay Area removed the suit to the District Court on diversity grounds. Meanwhile, DVI filed for Chapter 11 bankruptcy protection and assigned its rights against Bay Area to DVI Receivables XV, LLC. DVI Receivables hired U.S. Bank Portfolio Services (U.S. Bank) and granted it a power of attorney to pursue collections.

The District Court granted U.S. Bank’s motion to join the action as a plaintiff under Fed. R. Civ. P. 25(c). The court conducted a bench trial and granted U.S. Bank a $5,332,763.43 judgment, plus attorneys’ fees and costs. Bay Area’s motion for a new trial was denied, and it appealed. Pursuant to Fed. R. App. P. 10(e), we remanded the case to the District Court to determine whether it afforded Bay Area an opportunity to contest U.S. Bank’s joinder under Fed. R. Crv. P. 25(c). The District Court approved a stipulated supplement to the record and concluded Bay Area had a sufficient opportunity to oppose the joinder. We will affirm.

II.

A.

First, Bay Area argues that the District Court denied it an opportunity to contest U.S. Bank’s joinder as a plaintiff. We disagree. The District Court held two teleconferences with the parties, permitted Bay Area to file a brief in opposition to U.S. Bank’s motion to join and amended its order to facilitate Bay Area’s counterclaims against DVI. We are satisfied that the District Court granted Bay Area a sufficient opportunity to be heard on the matter.

Bay Area also contends the District Court abused its discretion in allowing U.S. Bank to join under Fed. R. Crv. P. 25(c). Rule 25(c) provides, in relevant part:

In case of any transfer of interest, the action may be continued by or against the original party, unless the court upon motion directs the person to whom the interest is transferred to be substituted in the action or joined with the original party.
Fed. R. Crv. P. 25(c) (2007).

U.S. Bank possessed a transferable interest in the action by virtue of its power of attorney and its contractual obligations to DVI Receivables XV. In addition, DVI remained a party to the action and was subject to Bay Area’s counterclaims. The District Court did not abuse its discretion when it permitted U.S. Bank to join the action as an additional plaintiff.

B.

Second, Bay Area argues that their agreements with DVI did not specify the applicable interest rate, and that therefore it was to be calculated as a six-percent simple rate, pursuant to Pennsylvania law. Where the parties fail to provide for a specific rate and method of computation, Pennsylvania law implies a six-percent rate calculated only upon the original principal. See 41 Pa. Stat. Ann. § 202 (West Supp.2006), and Murray v. Prudential Ins. Co. of Am., 18 A.2d 820, 823 (Pa.Super.1941). Here, there is no need to imply the interest rate or method of computation, because the parties agreed to the amount borrowed, the amount to be repaid and the schedule of repayment. The District Court properly inferred the applicable interest rate and method of computation from the agreed-upon sums. The court’s calculation of Bay Area’s liability was not clearly erroneous.

C.

Finally, Bay Area claims that the District Court clearly erred in finding that DVI credited it with unearned finance charges and that DVI did not impose penalty charges against them. Schedule No. 4, however, established the terms of the final restructuring, and therefore provided conclusive evidence of the parties’ intended agreement. Yocca v. Pittsburgh Steelers Sports, Inc., 578 Pa. 479, 854 A.2d 425, 436-37 (2005). Bay Area failed to show that they agreed to the terms of the final restructuring because of fraud or mistake.

III.

The District Court provided Bay Area with sufficient opportunity to challenge the joinder of U.S. Bank, and did not abuse its discretion in allowing U.S. Bank to join the action. Neither did the court err in calculating Bay Area’s obligations. We will affirm the court’s order.
