Opinion by
This case requires us to decide an unresolved question of Colorado law: whether prejudgment interest under section 5-12-102(1), C.R.S.2008, is recoverable in an insurer's equitable contribution action under former section 10-4-707(8) of the sunsetted Colorado No-Fault Act. Because we conclude that prejudgment interest is recoverable, we reverse that portion of the judgment and remand to determine and award prejudgment interest.
I. Background
After plaintiff, Safeco Insurance Company, paid Personal Injury Protection (PIP) benefits to its insured in connection with a 2001 multi-vehicle accident, it demanded contribution from defendants, Westport Insurance Corporation and Horace Mann Insurance Company, whose insureds were also involved.

When defendants did. not comply, Safeco brought this statutory contribution action. On remand from Safeco Ins. Co. v. Westport Ins. Corp.,
II Law
Under former section 10-4-707(8), "In the event two or more insurers are liable to pay benefits on the same basis, any insurer paying benefits shall be entitled to an equitable pro rata contribution from such other insurer." Ch. 94, see. 1, § 13-25-7(8), 1978 Colo. Sess. Laws 837 (subsequently codified at § 10-4-707(8) until entire No-Fault Act repealed effective July 1, 2008). This section does not mention recovery of either prejudgment or postjudgment interest.
In pertinent part, section 5-12-102(1) provides, "creditors shall receive interest ... (a) When money or property has been wrongfulty withheld ... from the date of wrongful withholding ... to the date judgment is entered." See generally Westfield Dev. Co. v. Rifle Inv. Assocs.,
Although the phrase "wrongfully withheld" is not defined in section 5-12-102, numerous cases recognize the General Assembly's intent to compensate an innocent party for the time value of money owed to that party. Seq, e.g., Goodyear Tire & Rubber Co. v. Holmes,
Statutory interpretation is a question of law subject to de novo review. Francis ex rel. Goodridge v. Dahl,
III. Analysis
In Safeco I,
Instead, they assert that the trial court properly declined to award prejudgment interest under section 5-12-102(1) because interest is not mentioned in former section 10-4-707(8), but is provided for in former seetion 10-4-708(1.8) (insured may obtain interest of eighteen per cent per annum on unpaid benefits "from the date the benefits recovered were due"). CH. 203, see. 1, 1991 Colo. Session Laws 1187. According to defendants, because the General Assembly "certainly knew how to deal with interest in this area ... we cannot infer that it was through mere inadvertence that it failed to provide for the interest that [Safeco] seeks." See Husson v. Meeker,

Furthermore, one of the purposes of the No-Fault Act is "to ensure prompt payment of benefits when due." Nat'l Farmers Union Prop. & Cas. Co. v. Estate of Mosher,
Moreover, denying prejudgment interest here would be unjust because while Safeco "followed the proper procedure," Safeco I,
Additionally, subordinating the mandate of section 5-12-102(1) that prejudgment interest "shall" be awarded where money has been wrongfully withheld to the silence of former section 10-4-707(8) concerning interest would violate the principle that a court should strive for a harmonious interpretation which avoids conflict between statutes. See, eg., Dawson v. Reider,
We also reject defendants' argument that because section 5-12-102 "codiffies] the doctrine of moratory interest in contract and property damage cases," Farmers Reservoir & Irrigation Co. v. City of Golden,
Because contribution prevents unjust enrichment, Colo. Dep't of Transp. v. Brown Group Retail, Inc.,
When a court appropriately applies the doctrine of unjust enrichment, the unjustly enriched party is generally liable for interest on the benefits received. D. Dobbs, The Law of Remedies § 8.5 (1978). Failure to award such interest would result in incomplete restitution to the petitioner. We conclude, therefore, that Martinez is entitled to a credit for the reasonable rental value of the property for the entire period of the respondents' possession thereof, plus interest, computed as provided by section 5-12-101, 2 C.R.S. (1978).
A prejudgment interest award "is necessary to avoid unjust enrichment." Dobbs, § 8.6(8), at 348-49. Hence, we agree that "the application of this principle is particularly well-suited to cases brought in equity insofar as it deters further wrongful delay of payment." Polygon Northwest Co. v. Am. Nat'l Fire Ins. Co.,
To the extent that Watson v. Public Service Co.,
Finally, unlike some jurisdictions where "in equitable actions the decision whether to award prejudgment interest lies entirely in the trial court's discretion," Taylor-McDonald v. Taylor,
Accordingly, we conclude that the trial court erred in refusing to award Safeco prejudgment interest under section 5-12-102(1).
IV. Conclusion
The judgment is reversed as to the denial of prejudgment interest, it is affirmed in all other respects, and the case is remanded. On remand, the trial court may hold a hearing before determining the amount of prejudgment interest, and shall amend the judgment to award such interest.
Chief Judge DAVIDSON and Judge STERNBERG * concur.
