The issue for decision is the propriety of the trial court’s ruling that personal injury protection coverages afforded by a business auto policy insuring fourteen corporately owned motor vehicles may be stacked.
On March 14, 1979, Clyde Wakefield, the president of Bill Kepple Machinery, Inc., was fatally injured while riding in a customer’s automobile. Federated Mutual Insurance Company (Federated) paid survivors economic loss benefits of $10,000, asserting that that amount exhausted the limits of the personal injury protection afforded under its policy insuring Bill Kepple Machinery, Inc.’s, motor vehicles. Mrs. Wakefield contended, and the trial court agreed, that the no-fault basic economic loss benefits applicable to each of the motor vehicles owned by Mr. Wakefield’s corporate employer should be stacked. W.e reverse.
William Kepple and Clyde Wakefield each owned 50% of the shares of William Kepple Machinery, Inc. Wakefield was the president. The corporation owned fourteen motor vehicles of various types. A 1973 Buick sedan was assigned to Wakefield and was used as a family car by the Wake-fields, who did not own an automobile.
All of the corporation’s vehicles were insured under one business auto policy issued by Federated. The policy provided liability and physical damage insurance as well as uninsured motorist coverage and personal injury protection (i.e., “PIP” no-fault basic economic loss benefits). A separate premium was charged for each coverage applicable to each motor vehicle insured under the policy. By endorsement William Kepple and Clyde Wakefield were deemed to be named insureds with respect to personal injury protection. A separate premium of $2.00 was charged for each person named in the endorsement.
The plaintiff concedes that the reverse pierce of the corporate veil, on which the decision in Roepke v. Western National Mutual Insurance Co., 302 N.W.2d 350 (Minn.1981), is based, is inapplicable here. See Kuennen v. Citizens Sec. Mut. Ins. Co., 330 N.W.2d 886 (Minn.1983). Relying, however, on the holding in Wasche v. Milbank Mutual Insurance Co., 268 N.W.2d 913 (Minn.1978), the plaintiff contends that the payment of separate premiums for the no-fault benefits applicable with respect to each vehicle described in the corporation’s insurance policy warrants stacking of those coverages. In Wasche we held that “the injured person shall be allowed to recover basic economic loss benefits under each no-fault coverage applicable to him as an *852insured to the extent of actual losses Id. at 919. (emphasis supplied). The issue is whether or not the separate no-fault coverages applicable with respect to each of the corporate vehicles are also applicable to Clyde Wakefield.
The priority of applicability of insurance for the payment of basic economic loss benefits is set out at Minn.Stat. § 65B.47 (1982). Subdivision 2 of § 65B.47 identifies the source of basic economic loss benefits payable as a result of an accident involving most employer-furnished vehicles:
In case of injury to an employee, or to his spouse or other relative residing in the same household, if the accident causing the injury occurs while the injured person is driving or occupying a motor vehicle other than a commuter van furnished by the employer, the security for payment of basic economic loss benefits is the security covering the vehicle or, if none, the security under which the injured person is an insured.
Thus, if Clyde Wakefield or his wife or children had been injured while driving or occupying the 1973 Buick sedan which Kep-ple Machinery furnished for the Wake-fields’ use or any other corporately owned automobile or truck, the security covering the involved vehicle would have constituted the source of basic economic loss benefits for each injured member of the Wakefield family. In such an event no-fault benefits would have been payable to the extent of each injured family member’s loss, subject to medical expense limits of $20,000 and an aggregate maximum of $10,000 payable on account of work loss, essential services expenses, funeral expenses and survivors' loss. Since the applicable security is that covering the involved motor vehicle, the security covering other corporate vehicles — even though insured under the same policy of insurance — is inapplicable and may not be stacked. Yaeger v. Auto-Owners Ins. Co., 335 N.W.2d 733 (Minn.1983); Roepke v. Western Nat’l Mut. Ins. Co., 302 N.W.2d 350 (Minn.1981). Even if the Wakefields had themselves owned one or more automobiles and were insureds under the policy insuring their owned vehicles, that security (with its potential for stacking no-fault benefits) would have been inapplicable pursuant to § 65B.47, subd. 2, since there was security covering the involved corporate vehicle. Furthermore, pursuant to the provisions of both the No-Fault Act and the policy, the Federated policy covering the corporation’s motor vehicles would have constituted the security for the payment of no-fault benefits regardless of the presence or absence of an endorsement designating Clyde Wakefield as an insured either by name or by virtue of his corporate office.
With respect, however, to injury sustained while driving or occupying or being struck by any motor vehicle other than one furnished by William Kepple Machinery, Inc., neither Clyde nor Sharon Wakefield nor any of the Wakefield children would be eligible for no-fault benefits payable through the Federated policy except by reason of the endorsement designating Clyde Wakefield as a named insured with respect to the personal injury protection.1 Nothing in the Minnesota No-Fault Automobile Insurance Act, Minn.Stat. §§ 65B.41 to 65B.71 (1982) requires a reparation obligor to extend personal injury protection to a corporate insured’s employees except while driving or occupying or being struck by an insured corporately owned vehicle. Thus, the applicability of the Federated policy for payment of basic economic loss benefits occasioned by Clyde Wakefield’s fatal injury while occupying a vehicle owned not by his employer but by his employer’s customer depends solely on the contractual obligation undertaken by the endorsement extending personal injury protection to named individuals — William Kepple and Clyde Wakefield. The premi*853um charge for the endorsement was $2.00 per named individual.
In short, the applicability of the Federated policy under the circumstances of this case is a function not of the basic plan of reparation security mandated by statute but of an endorsement which is not required by the statute. The coverage afforded by the endorsement is unrelated to and beyond the scope of the coverage afforded by the basic plan of reparation security purchased for a premium based on a per vehicle cost. The premium for the endorsement is based on the number of named individuals listed there; the number of motor vehicles covered in the basic plan and the premium charged for each covered vehicle is immaterial to the premium charge for the endorsement.
Subsequent to the issuance of the trial court’s order in this case, we held that no-fault benefits afforded by a commercial policy insuring more than one motor vehicle could not be stacked because the premium cost of the policy, which was based on the amount of the insured’s payroll, was not a function of the number of vehicles covered. Yaeger v. Auto-Owners Ins. Co., 335 N.W.2d 733 (Minn.1983). As we observed in Yaeger, “The rationale behind stacking is twofold: the legislature requires certain coverages in all policies; and, second, a premium having been paid for that coverage, the insurer is not to receive a windfall in premiums paid for coverage not honored.” Id. at 737. Neither of these bases is present here. Although personal injury protection is statutorily required in every policy, the extension of coverage provided by the endorsement to the Federated policy is not. The policy in question is not a family policy purchased by a policyholder to cover himself and the other members of his household. It is a commercial policy covering vehicles owned by a business corporation. As required by the statute, the policy affords no-fault benefits for any employee of the corporation or member of the employee’s household injured while driving or occupying an insured corporate vehicle. Nothing in the No-Fault Act, however, requires the policy issued to the corporate employer to cover the corporation’s employees or members of their families who are injured while occupying or through being struck by any other vehicle.
We have sometimes remarked that basic economic loss benefits protect persons, not vehicles. Wasche v. Milbank Mutual Insurance Co., 268 N.W.2d 913, 918 (Minn.1978). It might also be said that in general basic economic loss coverage follows the person, not the vehicle, for in most instances the No-Fault Act directs the injured person to look to his own policy regardless of whether or not it is associated with the vehicle involved in the accident. The risk being insured by each family policy is principally the risk of injury to the insured party or a covered member of his household, and the premium paid for each policy separately reflects that risk. Koons v. Nat’l Family Ins. Co., 301 N.W.2d 550, 553 (Minn.1981).
Here, however, the risk principally being insured against is the business-related risk of injury to the corporation’s employees. The premium paid to cover this risk takes into account the fact that an employee or a covered member of the employee’s household injured while a passenger or driver of a vehicle furnished by the corporation comes within a priority level which does not permit stacking. Minn.Stat. § 65B.47, subd. 2 (1982). Yaeger v. Auto-Owners Ins. Co., 335 N.W.2d 733 (Minn.1983). Neither the basic policy nor the premium include the risk of injury to an employee or members of his household in any other circumstances; the statutory plan requires the basic economic loss benefits to follow a particular vehicle rather than a person. Protection against the risk of injury to an employee or member of his household while occupying or through being struck by any vehicle except an insured employer-furnished vehicle is afforded only by virtue of the optional endorsement for which a single premium based on the number of individuals named in the endorsement is charged. In this context, then, it is appropriate to say that the endorsement provides single coverage for which only a single premium was paid even though the corporate employer owns several insured *854vehicles. Consequently, when either an employee named in the endorsement as an insured or a member of the employee’s household is injured, the single payment of benefits does not result in an unearned premium windfall to the insurer. As we said in Yaeger, “There is nothing to stack because, in the words of Wasche, there is only the single ‘no-fault coverage applicable to him as an insured.’ ” 335 N.W.2d at 738.
The term “stacking” has become so firmly established in insurance jargon that it is easy to forget that the principle of stacking is not enunciated in the No-Fault Act. Neither is it provided by the terms of an insurance policy. To the contrary, the Federated policy contains the customary provision (sometimes called an anti-stacking clause) limiting its liability for no-fault benefits to a maximum of $20,000 for medical expenses and a maximum aggregate amount of $10,000 for the other types of basic economic loss. In Wasche, however, we held that a policy provision which would deprive the insured of the mandatory coverage for which he had paid on each insured motor vehicle was void as against public policy and repugnant to the No-Fault Act. On the other hand, the unarticulated premise underlying the decision in Yaeger is that if — as is true in the present case— the single payment of benefits does not result in an unearned premium windfall to the insurer, the limitation of liability provision is compatible with both public policy and the No-Fault Act.
Finally, the proposition urged on us by the respondent — that although the statute precludes the stacking of no-fault benefits if the involved vehicle is an employer-furnished vehicle insured under the policy, the non-compulsory no-fault benefits provided by endorsement should be stacked if the involved vehicle is not associated with either the employer or the policy— seems to us anomalous. We hold that the no-fault benefits provided by optional endorsement cannot be stacked since the premium charge reflects a single coverage for the particular risk assumed.
Reversed.
. In conformity with the statutory definition of "insured”, an “eligible injured person” entitled to PIP under the Federated policy includes the named insured and his spouse and any person related to him by blood, marriage or adoption who resides in the same household with the named insured.
