MEMORANDUM ***

Factory waived its right to an appraisal by failing to request one within the time-frame specified by the insurance contract. The money it owed Springfield became due when the sixty-day period during which the contract permitted the parties to request an appraisal expired, provided that the amount Factory owed Springfield was either ascertained or readily ascertainable. *259The district court’s finding of fact that the amount Factory owed Springfield was readily ascertainable and that an award of prejudgment interest does not violate the parties’ Tolling Agreements was not clearly erroneous. In consequence, the district court did not abuse its discretion in awarding prejudgment interest.

Under Oregon law, Springfield was entitled to reasonable attorney’s fees. Or.Rev. Stat. § 742.061. The district court found that the original and supplemental fees requested by Springfield were reasonable. The district court found also that all of Springfield’s claims related to a common set of facts and that, as a result, apportionment of the requested fees was not appropriate. See Bennett v. Baugh, 164 Or.App. 243, 247-48, 990 P.2d 917 (1999). These findings are not clearly erroneous. In consequence, the district court did not abuse its discretion in awarding attorney’s fees.

AFFIRMED.
