OPINION
{1} The New Mexico Taxation and Revenue Department (New Mexico) and the State of Texas (Texas) appeal the trial court’s denial of their joint motion to intervene in a nationwide class action. The states sought to challenge the terms of the class action’s final settlement as a contravention of their unclaimed property acts. See NMSA 1978, §§ 7-8A-1 to -31 (1997, as amended through 2003); Tex. Prop.Code Ann. §§ 72.001 to 74.705 (Vernon 1985, as amended through 2003). We find that the Texas appeal was untimely filed and therefore do not consider the merits of its arguments. We hold that under the circumstances of this case, New Mexico’s unclaimed property act does not apply. We therefore affirm the denial of the intervention motion.
I. BACKGROUND
{2} The class action arose out of Massachusetts Mutual Life Insurance Company’s (MassMutual’s) practice of applying modal charges when policyholders pay premiums on an installment basis, either monthly, quarterly, or semi-annually, rather than annually. In December 1998, Plaintiff Floyd D. Wilson (Wilson) filed the lawsuit on behalf of a class of persons who at any time owned disability or life insurance policies issued by MassMutual and who paid any modal charges for their policies. Other named plaintiffs were subsequently added. They alleged breach of contract; breach of common law and statutory duty to disclose modal charges; and failure to account for the modal charge when calculating annual dividends, policy cash values, and amounts of insurance coverage.
{3} On February 22, 2002, the district court preliminarily approved the second of two settlements reached, class counsel having previously withdrawn his support for the first settlement. The district court scheduled a fairness hearing for June 20, 2002, to consider final approval of the second settlement. Under the terms of the settlement, MassMutual agreed to provide policyholders a certificate for each policy on which they paid a modal charge and to make various disclosures about modal charges. Class members could either use each certificate for $100 credit toward the purchase of select MassMutual products or redeem each certificate for $30 cash. The redemption period for the certificates was limited to a period of eighteen months from the date of issuance.
{4} The states, non-class members, filed a joint motion to intervene on May 30, 2002, and requested to appear at the fairness hearing. Their motion challenged the legality of the time-limited certificates and asserted that the “value [of certificates not redeemed after eighteen months] reverts to MassMutual, instead of being delivered to the states’ unclaimed property fund.” At the fairness hearing, the district court heard arguments concerning the applicability of the unclaimed property acts from both states and from proponents of the settlement. New Mexico additionally provided an oral offer of proof; Texas was granted leave to file an offer of proof by affidavit. On June 27, 2002, the district court issued two orders. One denied the motion to intervene; the other gave final approval to the settlement. The states appealed both orders.
{5} We consolidated the states’ appeals with those of six individuals or groups of individual class members who appealed the settlement’s final approval. The class members raised issues of class certification, the adequacy of notice, the fairness of the settlement, the level and allocation of attorney fees, and the awards to class representatives. This Court was notified shortly before oral argument that the class members had settled their six appeals; we subsequently granted the joint motion to dismiss the class members’ appeals. We therefore address only the states’ appeals.
II. DISCUSSION
{6} We first address two threshold questions: the timeliness of the Texas appeal and standing to move for intervention. We then turn to the intervention motion.
A. The Notice of Appeal by Texas Was Untimely Filed
{7} Wilson urges this Court to dismiss Texas’ notice of appeal for untimeliness. Rule 12-201(A)(2) NMRA 2004 requires that a notice of appeal be filed within thirty days of the entry of final judgment. The district court’s orders denying the intervention motion and approving the final settlement were filed on June 27, 2002; since the thirtieth day fell on a weekend, the notice of appeal was due Monday, July 29, 2002. See Rule 12-308(A) NMRA 2004. The appeal was filed on July 30, one day late.
{8} The district court’s authority to grant an extension is governed by Rule 12-201(E). Where the motion for an extension is filed prior to the expiration of the thirty-day time limit, the extension of time for filing a notice of appeal may be granted upon a finding of good cause. Rule 12-201 (E)(1). When the motion is filed after the expiration of the thirty-day deadline, there must be a finding of excusable neglect or circumstances beyond the control of the appellant. Rule 12-201(E)(2). The district court has sixty days to grant an extension to appeal. Rule 12-201(E)(4).
{9} Texas dispatched its notice of appeal on July 24, 2002, in a United Parcel Service (UPS) second-day air overnight package; the notice was not delivered by UPS until July 30. On August 9, 2002, Texas incorrectly sought leave from this Court for an extension to file its notice of appeal; we directed Texas to request the extension from the district court, which Texas did on August 12, 2002. Without a hearing or a notice to the parties, the district court ordered the extension on August 14, 2002, upon a finding of good cause. Unaware of the court’s order, Wilson on August 20, 2002, timely objected to Texas’ motion for an extension. The next day, Wilson learned of the order and filed a motion for reconsideration. Wilson challenged the court’s use of the good cause standard and argued that Texas was unable to meet the proper standard of excusable neglect or circumstances beyond its control. New Mexico and MassMutual joined Texas in opposing Wilson’s motion for reconsideration. Following a hearing, the district court issued an order on September 24, 2002, that denied Wilson’s motion and substituted a finding of circumstances beyond Texas’ control for the good cause finding in the court’s August 14 order. Wilson then asked this Court to dismiss the Texas appeal on the grounds that the district court lacked jurisdiction for the September 24 order because the sixty-day period for granting extensions had expired; or, alternatively, that the district court’s finding of circumstances beyond the control of Texas was unsupported by the record.
{10} We review de novo the question of whether a district court has authority to grant an extension of time for filing a notice of appeal. See Chavez v. U-Haul Co.,
{11} Furthermore, the circumstances in this case are not those that warrant the extension. The timely filing of a notice of appeal is a mandatory precondition to jurisdiction, not an absolute jurisdictional requirement. Executive Sports Club, Inc. v. First Plaza Trust,
{12} Nor are these unusual circumstances outside of Texas’ control. We view the circumstances here as similar to those in San Juan, where plaintiffs’ counsel also relied on a courier service and argued that the courier service had misinformed her that the clerk’s office was closed. See San Juan,
B. New Mexico Has Standing
{13} Standing is a principle that ensures only those with a legitimate interest can participate in a lawsuit. De Vargas Sav. & Loan Ass’n of Santa Fe v. Campbell,
{14} We find Wilson’s reliance on New Mexico Right to Choose/NARAL misplaced; that case does not stand for the proposition that the requirements for standing and intervention are identical, or that a party unable to intervene automatically lacks standing. See id. (explaining that the power of the court to confer standing “does not equate with rights of indiscriminate intervention” (internal quotation marks and citations omitted)); see also Chiles v. Thornburgh,
{15} Wilson also relies on Paterson v. Texas,
{16} We do not find the reasoning in Paterson persuasive. Paterson relies on Hays, which concerns a private individual’s standing, not the state’s standing to enforce a statute granting express authority to sue. See Hays,
{17} New Mexico asserts that its standing derives from the enforcement powers granted in the act itself. See § 7-8A-22 (“The administrator may maintain an action in this or another state to enforce the Uniform Unclaimed Property Act.”). We agree with New Mexico and observe that other jurisdictions have premised standing by a state on its right to enforce its statutes. See Alaska v. United States Dep’t of Transp.,
{18} We now consider the motion to intervene.
C. The Motion to Intervene Was Properly Denied
{19} We concluded above that New Mexico has standing to assert violation of the unclaimed property act. However, as we discussed above, standing does not automatically confer the interest necessary to require intervention. See N.M. Right to Choose/NARAL,
{20} ”[I]ntervention is the proceeding whereby a person is permitted to become a party in an action between other persons after which litigation proceeds with both original and intervening parties.” Richins v. Mayfield,
1. Standard of Review
{21} Absent a clear abuse of discretion, we will uphold the district court’s denial of the motion to intervene. See Solon v. WEK Drilling Co.,
2. Merits of the Arguments
a. Statutory Right to Intervene
{22} We first analyze New Mexico’s right to intervene under Rule 1-024(A)(1). As discussed above, Section 7-8A-22 of the act provides that “[t]he administrator may maintain an action in this or another state to enforce the Uniform Unclaimed Property Act.” Without authority from New Mexico, the state suggests that this provision confers an unconditional right to intervene. We disagree.
{23} We find no precedent in New Mexico allowing intervention under Rule 1-024(A)(1) in the absence of direct statutory authorization. We observe that federal courts applying the federal counterpart to this rule have granted intervention where a statute expressly provides for such intervention. See Illinois v. Outboard Marine Corp.,
{24} Where federal statutes say nothing of intervention, courts are not apt to recognize an unconditional right to intervene under thp federal rule. See 7C Wright, supra § 1906, at 245; see also State ex rel. Wilson v. Wilson,
b. Interest in the Litigation
{25} We next turn to Rule 1-024(A)(2). To succeed in its motion under this paragraph, New Mexico had to demonstrate each of three prerequisites: “namely: (1) interest; (2) impairment of that interest; and (3) inadequacy of representation of that interest.” Chino Mines Co.,
{26} New Mexico’s act (also referred to herein as the act) is fashioned on the 1995 Uniform Unclaimed Property Act (1995 UPA), promulgated by the National Conference of Commissioners on Uniform State Laws. See Unif. Unclaimed Prop. Act §§ 1-33 (superseded 1995) 8C U.L.A. 87-149 (2001). Property that is presumed abandoned is subject to the custody of the state. NMSA 1978, § 7-8A-4 (1997). Property is presumed abandoned if it is unclaimed by the apparent owner for a specified period of time — in this case, for five years. Section 7-8A-2(a). Once the period of time has passed and the property is presumed abandoned, the holder of the property must turn it over to the state. Section 7-8A-8. Any unclaimed funds New Mexico receives are deposited into the state’s general fund. Section 7-8A-13. The property can be claimed by its owners at any time. Section 7-8A-15. Wilson and MassMutual argue that the act does not apply for various reasons, including their view that the certificates are not property as defined in the act. 1 Based on the following analysis, we conclude that the certificates are not property.
{27} To establish whether the certificates are property, we first look to the act itself in order to give effect to the plain meaning of the words the legislature used. See Regents of the Univ. of N.M. v. N.M. Fed’n of Teachers,
{28} ’’Property” is defined in pertinent part in the act as “a fixed and certain interest in intangible property that is held, issued, or owed in the course of a holder’s business.” Section 7-8A-l(13). The same definition is used in the 1995 UPA. See Unif. Unclaimed Prop. Act § 1(13), 8C U.L.A. 98. New Mexico correctly points out that the word “ordinary” was dropped between the 1981 and 1995 UPAs. The 1981 UPA, as well as the previous version of New Mexico’s act, which was enacted in 1989 and was based on the 1981 UPA, incorporated the phrase “ordinary course of business” into the section concerning “[p]roperty presumed abandoned.” See NMSA 1978, § 7-8-3CA) (1989) ([A]ll intangible property ... that is held, issued or owing in the ordinary course of a holder’s business ... is presumed abandoned.” (New Mexico’s 1989 act)). Neither the 1981 UPA nor New Mexico’s 1989 act included a definition of property in the section on definitions.
{29} New Mexico does not argue that there is a difference in meaning between “ordinary course of business” and “course of business” and does not provide us with any case law interpreting the phrases differently. We have not located any such case law. See, e.g., Blue Cross & Blue Shield of Fla., Inc. v. Dep’t of Banking & Fin.,
{30} We review the use of “course of business” or “ordinary course of business” in non-UPA and UPA cases to ascertain the plain meaning. Both phrases have been applied with a consistent meaning in a variety of contexts outside of the UPA. See, e.g., In re Energy Coop., Inc.,
{31} Courts do appear to apply the same meaning to the phrases in UPA cases; however, we observe that in these cases, whether plaintiffs were acting in the course of business or ordinary course of business was not in dispute. See, e.g., Blue Cross & Blue Shield of Fla., Inc.,
{32} We therefore interpret course of business to mean business practice that is routine, regular, usual, or normally done. The course of business for MassMutual is to sell insurance and other financial products. The certificates being issued as part of the settlement are not part of the company’s regular line of products; nor is the issuance of certificates a routine, usual, or normal practice. Instead, they are being issued as a result of a one-time settlement. Because they were not held, issued, or owed in the course of MassMutual’s business, we conclude that the certificates do not meet the definition of property under the act. As a result, New Mexico failed to establish that it had an interest in the settlement necessary for intervention under Rule 1-024(A)(2).
{33} Since we conclude that the unclaimed property act does not apply in this case, we do not consider the remaining issues concerning the act raised by New Mexico, including whether the act may be voluntarily waived. Since New Mexico does not have the right to intervene, we do not consider any other issues raised by the State.
III. CONCLUSION
{34} We dismiss the Texas appeal. We hold that the district court did not abuse its discretion in denying the motion to intervene, and we therefore affirm the denial.
{35} IT IS SO ORDERED.
Notes
. Although Plaintiffs argued in their brief that the act did not apply to the certificates, they reversed their position at oral argument and stated that the certificates were property subject to the act under certain conditions. We note this reversal.
