The issues presented are: 1) whether a municipality which contracts with the Oklahoma Tax Commission for the collection of municipal taxes under the authority of 68 O.S.Supp.1986 § 27021 is entitled to interest earned by taxes deposited in the State Treasury; and 2) if the municipality is entitled to investment interest, *1302whether it may recover interest deposited to the state’s general revenue fund.2 In accordance with our pronouncement in City of Oklahoma City v. Oklahoma Tax Comm’n, 789 P.2d 1287 (Okla.1990), we find that: 1) the interest earned on municipal sales tax revenues is an accretion or increment to the principal tax. Pursuant to the Okla. Const. art. 10, § 19,3 the total i.e., principal and interest, must be expended for the purpose levied; and 2) because the fund representing interest earned on the investment of the municipal sales taxes has been appropriated, it is not recoverable.4
We do not agree with the Court of Appeals characterization of the Tax *1303Commission as a “vendor.” This appellation is not supported by 68 O.S.Supp.1986 § 2702 which refers to a “collecting vendor” and a “vendor” who fails to remit taxes collected from the consumer. Such a vendor is subject to the charge of embezzlement. Because “vendor” is not defined within the statute, it is given its plain and ordinary meaning.5 Vendor ordinarily means one who sells.6 It is clear from the plain meaning of the word “vendor” in § 2702 that it refers to the merchant who collects the tax from the consumer. In some instances, when money enters the state treasury to be held or paid over according to law, it is held in trust. However, when the Legislature referred to a trustee in § 2702, the language used, “as trustee, the collecting vendor,” is clear. The vendor is deemed to be holding the taxes collected from the consumer in trust for the municipality.7
In the companion case, City of Oklahoma City v. Oklahoma Tax Comm’n, 789 P.2d 1287 (Okla.1990), also decided today, the Tax Commission asserted that such a holding would “strike at the heart of the State’s fiscal integrity,” and that if the City has a valid claim to interest as an accretion to principal, it is against the State Treasurer. This argument is unpersuasive. Our holding is precisely the position the Legislature recently embraced by amending 68 O.S.Supp.1986 § 2702,8 and its enactment of a new law providing for the establishment of “sales tax remitting accounts.” 9 The Legislature amended *1304§ 2702 effective November 1, 1989. The amended statute provides for all sales taxes, including penalties and interest, collected on behalf of a municipality to be deposited in a sales tax remitting account. House Bill 1330, codified as 68 O.S.Supp.1989 § 1373, provides for the creation of the sales tax remitting account. Section 4 of § 1373 now provides for the distribution of the proportionate amount of interest earned to municipalities on a monthly basis.
The result in this cause need not affect the State’s fiscal integrity. Absent a contract executed in accordance with 68 O.S. Supp.1986 § 2702, the revenues from municipal taxes would never be deposited in the state treasury; and there would be no dispute over entitlement to the interest earned. It would belong to the municipality investing the tax. At the end of any contract term, Oklahoma City or any other municipality could elect not to contract for these services. The argument that the state’s fiscal health depends upon an appropriation of the interest is unconvincing.
Adoption of this holding need not disrupt the state treasury’s machinery. The machinery to set up an individual account for the deposit of municipal tax revenues existed before the Legislature’s intervention. Title 62 O.S.Supp.1989 § 7.2 provides for a Special Agency Account Board with the authority to approve the establishment of agency special accounts in the official depository of the state treasury. Such an account could be utilized to segregate municipal tax monies entering the state system. Interest on these accounts could then be paid to the appropriate municipality as part of the monthly disbursal.10
All monies representing interest earned from the investment of municipal sales taxes have been appropriated. There is no fund from which the interest earned can be recovered. Therefore, although the cause is reversed, there is no remedial action which could be taken on remand.
CERTIORARI GRANTED; OPINION OF THE COURT OF APPEALS VACATED; REVERSED.
HODGES, LAVENDER, DOOLIN and SUMMERS, JJ., concur. HARGRAVE, C.J., OPALA, V.C.J., and SIMMS, J., dissent.. Title 68 O.S.Supp.1986 § 2702 provides:
"The governing body of any incorporated city or town and the Oklahoma Tax Commission *1302are authorized and empowered to enter into contractual agreements whereby the Oklahoma Tax Commission shall have authority to assess, to collect and to enforce any taxes or, penalties or interest thereon, levied by such incorporated city or town, and remit the same to such municipality. Said assessment, collection, and enforcement authority shall apply to any taxes, penalty or interest liability existing at the time of contracting. Upon contracting, the Oklahoma Tax Commission shall have all the powers of enforcement in regard to such taxes, penalties and interest as are granted to or vested in the contracting municipality. Such agreement shall provide for assessment, collection, enforcement, and prosecution of such municipal tax, penalties and interest, in the same manner as and in accordance with the administration, collection, enforcement, and prosecution by the Oklahoma Tax Commission of any similar state tax. The municipality shall agree to refrain from any assessment, collection, or enforcement of the municipal tax except as specified in the agreement. Such agreement shall authorize the Oklahoma Tax Commission to retain an amount not to exceed one and three-fourths percent (P/4%) as a retention fee of municipal tax collected for services rendered in connection with such collections. All funds retained by the Oklahoma Tax Commission for the collection services to municipalities shall be deposited in the Oklahoma Tax Commission Revolving Fund in the State Treasury.
Provided that the Oklahoma Tax Commission and the governing body of any incorporated city or town may enter into contractual agreements whereby the municipality would be authorized to augment the enforcement, collection and prosecution of the municipal tax in those contracting municipalities. Such agreements shall provide that the municipality and the Oklahoma Tax Commission may exchange necessary information to effectively carry out the terms of such agreements. The municipality, its officers and employees shall preserve the confidentiality of such information in the same manner and be subject to the same penalties as provided by Section 205 of this title, provided that the municipal prosecutor and other municipal enforcement personnel may receive all information necessary to augment the enforcement and prosecution of municipal sales tax ordinances. Any sum or sums collected or required to be collected pursuant to a municipal sales tax levy shall be deemed to be held in trust for the municipality, and, as trustee, the collecting vendor shall have a fiduciary duty to the municipality in regards to such sums and shall be subject to the trust laws of this state. Any vendor who fails to remit the municipal sales tax after the tax has been collected from the consumer, and appropriates the tax held in trust to his own use, or to the use of any person not entitled thereto, without authority of law, shall be guilty of embezzlement."
This section was amended effective October 1, 1989, see note 8, infra.
. The City of Oklahoma City did not respond to the Petition for Certiorari. However, in its response to the petition for rehearing before the Court of Appeals, the City, without conceding the legal issue, agreed to a settlement that would involve only funds held during fiscal year 1988-89.
. The Okla. Const, art. 10, § 19 provides:
"Every act enacted by the Legislature, and every ordinance and resolution passed by any county, city, town, or municipal board or local legislative body, levying a tax shall specify distinctly the purpose for which said tax is levied, and no tax levied and collected for one purpose shall ever be devoted to another purpose.”
. On January 26, 1990, we ordered the parties to show cause why this case should not be dismissed as moot in light of the Legislature's enactment of H.B. 1330, see note 9, infra. The City responded that it had no objection to a dismissal of the cause if funds representing interest earned had been appropriated. The State Treasurer responded that all monies which might represent interest earned on the municipal sales taxes had been appropriated to the Constitutional Reserve Fund. Despite the fact that the money has been appropriated, the State Treasurer opposes dismissing the cause as moot. Our decision to release an opinion is based upon our concern with the Court of Appeals' characterization of the Tax Commission as a "vendor,” and because failure to issue an opinion would leave the issue of the recovery of appropriated monies representing interest undecided.
