OPINION
In this fifth appeal arising from a loan transaction between business partners, James Trapp disputes three components of the calculation of prejudgment interest: the starting date, the ending date, and the interest rate. Lowell Hancuh and Han-cuh’s company, AAA Wholesale Trucks, Inc. (collectively Hancuh), appeal the denial of prejudgment interest on the remaining principal of a usurious loan. We find no reversible error in the calculation and affirm.
FACTS
This litigation, generated by the partnership between Trapp, Hancuh, and a third person, has greatly exceeded the brief life of the partnership. The three partners formed LAW Properties in March 1989. In October 1989 Hancuh loaned Trapp $57,500, secured by Trapp’s partnership interest in LAW Properties. Trapp defaulted on the loan in April 1990, and Hancuh seized Trapp’s partnership interest in May 1990.
Trapp sued Hancuh in June 1993 and, on appeal, this court held that: (1) Hancuh’s loan to Trapp was usurious; (2) the seizure was unjustified; (3) Trapp was entitled to the value of the seized partnership interest; (4) Hancuh was required to forfeit the interest and pay penalties provided by the usury
*63
statute; and (5) Trapp was obligated to pay the remaining loan principal.
Trapp v. Hancuh,
In computing the prejudgment interest, the district court first determined that Trapp’s claim for the value of his partnership interest was unliquidated and not readily ascertainable. The district court computed prejudgment interest from June 1, 1993, the date Trapp brought this action, to July 23, 1993. The district court used July 23 as a termination date because Hancuh offered Trapp $22,000 to settle the claim on that date. Trapp rejected the offer and made a number of counteroffers. Trapp’s final unaccepted offer, on February 18, 1994, was for Hancuh to pay him $271,500. The district court found that Hancuh’s offer was closer to the actual award than Trapp’s final offer and therefore Trapp was not entitled to prejudgment interest after July 23, 1993. In computing the setoff from Trapp’s recovery, the district court denied Hancuh any prejudgment interest on the loan’s outstanding principal, concluding that it was prohibited under the mandatory interest forfeiture provided by the usury remedy.

ISSUES
I. Did the district court err in selecting the starting date for the accrual of prejudgment interest?
II. Did the district court err in selecting the ending date for the accrual of prejudgment interest?
III. Did the district court err in using the interest rate and method of calculation provided by Minn.Stat. § 549.09 to calculate prejudgment interest?
IV. Did the district court err in denying Hancuh interest on his loan to Trapp?
ANALYSIS
In Minnesota, both statute and common law govern the award of prejudgment interest. Minn.Stat. § 549.09 (1996);
Potter v. Hartzell Propeller, Inc.,
I
Prior to 1984, prejudgment interest was available only on liquidated claims and on unliquidated claims if the amount was readily ascertainable.
Casey v. State Farm Mut. Auto. Ins. Co.,
By making an exception for prejudgment interest “allowed by law,” the legislature supplemented, but did not replace, the existing common law allowing prejudgment interest.
Seaway Port Auth. v. Midland Ins. Co.,
The district court applied the prejudgment interest statute to compute the *64 interest on the value of Trapp’s partnership from the commencement of the action. Id. Trapp contends that the interest should be computed under the common law from the date his claim arose (when his partnership interest was seized) because it is a liquidated or readily ascertainable unliquidated claim.
Prejudgment interest from the time the claim arises is appropriate when the amount demanded can be ascertained by computation or reference to generally recognized standards and does not depend on a contingency.
Jostens, Inc. v. CNA Ins., Continental Cas. Co.,
The record supports the district court’s finding. The parties initially disputed whether book or market value should be used. Trapp apparently argued in the district court that his interest was worth $150,-000 and Hancuh argued that it was worth substantially less.
Trapp,
The divergent partnership valuations and the litigation necessary to establish the valuation adequately support the district court’s finding that the value was not readily ascertainable. Relying on that finding, the district court properly used the commencement of the litigation as the starting date for computing prejudgment interest.
II
The district court used July -23, 1993, as the ending date for the prejudgment interest calculation. Trapp argues that this date is erroneous because his February 18, 1994 counteroffer superseded the effect of Han-cuh’s July 23, 1993 offer. Trapp misinterprets the statute. The statute does not require either party to make a settlement offer or respond to an offer made by the other party. Minn.Stat. § 549.09, subd. 1(b);
Hodder v. Goodyear Tire & Rubber Co.,
We reject Trapp’s argument that the su-persession provision should be read to mean that the most recent offer by either party supersedes all prior offers by both parties. He bases his interpretation on
Stewart v. Anderson,
who suffered a cutoff of prejudgment interest rights due to the neglect of an offer, could resurrect those rights by making another offer at a later date that either attracted no response or was the closest to the actual verdict.
Steivart,
We acknowledge that
Stewart’s
language could be read broadly to support Trapp’s global supersession argument, but a narrower reading is required by the statute and the applicable easelaw. Trapp’s interpretation of
Stewart
would permit plaintiffs to wait until immediately before trial to make an offer. The offer would erase the defendant’s prior offers, if any, and preserve prejudgment interest for the plaintiff. This interpretation is inconsistent with the legislature’s goal of encouraging settlement.
See Hodder,
Trapp’s reading of the statute would also impede the application of the closer-offer provision in the prejudgment interest statute. When a plaintiff prevails on a claim, a defendant’s offer that is closer to the award than a plaintiffs offer, if any, terminates the accrual of the prejudgment interest. Minn.Stat. § 549.09, subd. 1(b). To give effect to this provision, each party’s most recent offer, if any, must retain its legal effect. Minn.Stat. § 645.26, subd. 1 (1996) (courts should construe statutory provisions so each provision is given effect);
see Imlay v. City of Lake Crystal,
This reading of the statute allows the superseding and closer-offer provisions of the statute to work together in a sequential manner. After a court determines which offer is each party’s most recent offer, if any, the court then determines which party’s offer is closer to the awarded amount. This closest-offer provision in the statute advances the statute’s goal of moving the parties’ positions closer together over time, toward a settlement.
See Hodder,
Between Hancuh and Trapp, the offer closest to the judgment amount was not the last offer, but it was Hancuh’s last and most recent offer. The record supports the district court’s finding that Hancuh’s offer was closer to the award. Applying the superseding and closer-offer provisions in the statute, we affirm the prejudgment interest ending date used by the district court.
Ill
The prejudgment interest statute provides that interest is computed as simple interest per annum, based on a bank-discounted secondary market yield of one-year treasury bills. Minn.Stat. § 549.09, subd. 1(c) (1996). Despite the specific provisions of the statute, Trapp argues that the district court erred by not using a common-law interest rate and by not compounding interest.
The cases Trapp relies on do not support his argument.
Specialized Tours, Inc. v. Hagen
supplied an interest rate for prejudgment interest on securities fraud violations because Minn.Stat. § 80A.23 allowed prejudgment interest but did not specify the rate of interest.
*66
Trapp’s assertion that
Fire Insurance Exchange v. Adamson Motors
used a compound interest rate is simply incorrect.
IV
The final issue is Hancuh’s claim that the district court erred in denying him interest on the remaining principal of his loan to Trapp. The loan underlying this serial litigation was determined to be usurious in the first appeal. Neither of Hancuh’s arguments creates an exception from the statutory forfeiture of interest on usurious loans. See Minn.Stat. § 334.011, subd. 2 (1996) (providing the penalty that usurious lender forfeits all interest on its loan).
Hancuh’s first argument, that the obligation is a debt rather than a loan is a fallacious characterization. The amount is both a debt and a loan, depending on whether it is viewed from Hancuh’s or Trapp’s perspective. Calling it a debt does not exempt it from the interest prohibition on usurious loans.
Hancuh’s second argument is that he is not required to forfeit all interest on the loan, but only the usurious portion of the interest. This argument is based on a misreading of his cited authority,
Citizen’s National Bank of Willmar v. Taylor,
DECISION
The district court did not err in determining that Trapp’s claim was not liquidated or readily ascertainable. The court selected the correct starting and ending dates for the accrual of prejudgment interest, and it used the correct rate of interest and method of calculation. The court also correctly held that Hancuh could not recover prejudgment interest on his loan to Trapp.
Affirmed.
Notes
. The text of the statute establishes the procedure:
Except as otherwise provided by contract or allowed by law, preverdict, preaward, or prereport interest on pecuniary damages shall be computed * * * from the time of the commencement of the action * * * or the time of a written notice of claim, whichever occurs first, except as provided herein. * * * If either party serves a written offer of settlement, the other party may serve a written acceptance or a written counteroffer within 30 days. After that time, interest on the judgment or award shall be calculated by the judge or arbitrator in the following manner. The prevailing party shall receive interest on any judgment or award from the time of commencement of the action * * * or the time of a written notice of claim, * * * until the time of verdict, award, or report only if the amount of its offer is closer to the judgment or award than the amount of the opposing party’s offer. If the amount of the losing party’s offer was closer to the judgment or award than the prevailing party’s offer, the prevailing party shall receive interest only on the amount of the settlement offer or the judgment or award, whichever is less, and only from the time of commencement of the action * * * or the time of a written notice of claim[.] * * * Subsequent offers and counteroffers supersede the legal effect of earlier offers and counteroffers.
