This is an appeal from the judgment of the trial court granting, in part, the application of the United States Fidelity and Guaranty Company (USF&G) to vacate an arbitration award, and denying the application of Norman Mass, as executor of the estate of Sara Louise Mass and on behalf of his minor children Daniel and Jessica (Mass), to vacate in part or modify the arbitration award. We affirm the judgment of the trial court.
Most of the facts essential to the disposition of this appeal were stipulated to by the parties. On April 18, 1988, an automobile operated by Sara Louise Mass, in which her two minor children, Daniel Mass and Jessica Mass, were passengers, was struck broadside on a residential street in Fairfield by an automobile driven by Christopher Flynn, who was intoxicated, while traveling at a speed in excess of fifty miles per hour. The accident resulted in the death of Sara Mass and in personal injuries to Daniel and Jessica Mass. On and prior to April 18,1988, USF&G and Norman Mass, the husband of Sara and father of Daniel and Jessica, were parties to an automobile insurance contract. The contract, which covered the Masses’ two automobiles, provided uninsured motorist coverage1 in the amount of $500,000 for each vehicle. The contract also provided [633]*633for arbitration in case of a disagreement between the parties concerning uninsured motorist claims. On and prior to April 18,1988, Norman and Sara Mass were also parties to another insurance contract with USF&G, denominated a “Personal Excess Policy,” with a face value of $1,000,000, which listed the automobile insurance contract as underlying coverage. Because Flynn carried inadequate liability insurance, Mass sought uninsured motorist recovery under both USF&G policies.
On November 1, 1989, a panel of three arbitrators rendered a decision regarding the amount of insurance coverage available under the Masses’ policies with USF&G and the amount of damages suffered by the estate of Sara Mass and the Masses’ two minor children. The arbitrators ruled that $2,000,000 was available to the claimants: $500,000 on each of the Masses’ two automobiles under the automobile insurance contract plus $1,000,000 under the personal excess policy. The arbitrators determined that the damages suffered were as follows: $1,700,000 by the estate of Sara Mass; $50,000 by Daniel Mass; and $50,000 by Jessica Mass.
Both USF&G and Mass applied to the trial court to vacate the arbitration award. In its application, USF&G asserted that the personal excess policy issued to the Masses did not, by its terms and conditions, provide uninsured motorist coverage, and, further, that USF&G was not obligated under General Statutes § 38-175c to provide such coverage.2 USF&G claimed, therefore, [634]*634that the arbitrators’ ruling should be vacated to the extent that it concluded otherwise. In his application [635]*635to the trial court, Mass sought to have the arbitrators’ award vacated in part or modified to increase the amount of damages found to have been suffered by Sara, Daniel and Jessica Mass and of uninsured motorist coverage found to exist under the two USF&G policies. Mass claimed that the arbitrators incorrectly computed the amount of uninsured motorist coverage as $2,000,000, rather than $3,000,000, because they did not stack the $1,000,000 of coverage available under the personal excess policy. Mass also sought to have the amount of damages increased to at least $7,000,000.
The trial court, relying on Cohn v. Pacific Employers Ins. Co., 213 Conn. 540, 569 A.2d 544 (1990), concluded that the personal excess policy did not extend the Masses’ underlying uninsured motorist coverage because it (1) required that the insured be responsible for maintaining uninsured motorist coverage, and (2) lacked any agreement requiring USF&G to provide excess uninsured motorist coverage. The trial court therefore granted USF&G’s application to vacate the arbitrators’ award to the extent that the award included the personal excess policy. The trial court did not find the miscalculation of damages that Mass had claimed, however, and, therefore, denied Mass’ application. This appeal to the Appellate Court followed. We transferred the appeal to ourselves pursuant to Practice Book § 4023.
On appeal, Mass claims that the trial court improperly failed to conclude that: (1) the personal excess policy provided uninsured motorist coverage; (2) $3,000,000 in uninsured motorist coverage was available under the two policies with USF&G; and (3) the estate of Sara Mass was entitled to at least $3,000,000 in damages. USF&G presents only one issue on appeal, which we shall address in conjunction with Mass’ first claim: whether General Statutes § 38-175c requires that the personal excess policy that USF&G [636]*636issued to the Masses provide uninsured motorist coverage when such coverage had already been provided in a separate policy purchased exclusively for automobile liability protection in accordance with § 38-175c.
Mass first claims that the trial court improperly failed to conclude that the personal excess policy issued by USF&G provided uninsured motorist coverage. Mass argues that the trial court misapplied this court’s holding in Cohn v. Pacific Employers Ins. Co., supra, because the personal excess policy in this case is a liability policy, not an indemnity policy, as was the policy at issue in Cohn. Mass contends that since the personal excess policy covers liability for damages arising out of the operation of an automobile,3 it is an “automobile liability policy” within the meaning of § 38-175c and, therefore, must provide uninsured motorist coverage pursuant to § 38-175c (a) (2). USF&G argues that the personal excess policy issued to the Masses was not required to provide uninsured motorist coverage under § 38-175c because such coverage had already been provided in accordance with § 38-175c in a separate automobile insurance contract. We are persuaded that the personal excess policy is not an “automobile liability policy” within the meaning of the statute, and, therefore, that the trial court properly concluded that the policy is not required to provide uninsured motorist coverage.
In support of his argument, Mass places substantial reliance on the distinction between an indemnity policy and a liability policy that this court made in Cohn. In that case, we affirmed the conclusion of the trial court [637]*637that an excess policy issued to the plaintiff was not an automobile liability policy within the meaning of § 38-175c because the terms of the policy unequivocally established that it was an indemnity policy.4 What we did not decide in Cohn, however, was whether an excess policy whose language provided for liability must comply with the uninsured motorist statute.5
Unlike the policy involved in Cohn, the personal excess policy issued to the Masses by USF&G did not require that the insured’s liability be discharged before a cause of action against the insurer would accrue. Id., 547. The policy provided that USF&G would pay damages on behalf of the insured, subject to certain exclusions. Uninsured motorist coverage was not specified in the list of exclusions.6

We are persuaded that the personal excess policy is not an “automobile liability policy” within the meaning of the statute, and, therefore, that the trial court properly concluded that the policy is not required to provide uninsured motorist coverage.
In support of his argument, Mass places substantial reliance on the distinction between an indemnity policy and a liability policy that this court made in Cohn. In that case, we affirmed the conclusion of the trial court [637]*637that an excess policy issued to the plaintiff was not an automobile liability policy within the meaning of § 38-175c because the terms of the policy unequivocally established that it was an indemnity policy.4 What we did not decide in Cohn, however, was whether an excess policy whose language provided for liability must comply with the uninsured motorist statute.5
Unlike the policy involved in Cohn, the personal excess policy issued to the Masses by USF&G did not require that the insured’s liability be discharged before a cause of action against the insurer would accrue. Id., 547. The policy provided that USF&G would pay damages on behalf of the insured, subject to certain exclusions. Uninsured motorist coverage was not specified in the list of exclusions.6 The policy further provided that “[rjegardless of the number of insureds, claims or injured persons, the most [USF&G will] pay as damages resulting from one occurrence shall not exceed [$1,000,000],” but that “[i]f primary insurance and this policy cover an occurrence which results in personal injury or property damage, [USF&G will] pay damages which exceed the total applicable primary insurance [638]*638limits.” The declarations to the policy provided, inter alia, that the insured shall have “primary insurance” for “auto liability,” with limits of $500,000 per accident or occurrence.7 According to the evidence presented at the arbitration hearing, the Masses paid a total premium of $173 for the personal excess policy during the relevant policy period. The evidence also established that they paid a separate premium of $1000 for the automobile insurance contract for the six month period during which the accident occurred, of which fifty-four dollars went to uninsured motorist coverage.
Pursuant to § 38-175c (a) (2), an insurer is required to provide an insured with uninsured motorist coverage equal to the amount of automobile liability coverage purchased unless the insured elects a lesser amount in writing, although in no event may he elect less than the statutory minimum specified in General Statutes § 14-112 (a).8 In Travelers Indemnity Co. v. Malec, 215 [639]*639Conn. 399, 576 A.2d 485 (1990), we examined the legislative history and development of § 38-175c. “Prior to the enactment of § 38-175c; see Public Acts 1967, No. 510; [uninsured motorist] coverage, although available, was not required. Coverage was limited to the amount requested by the insured. In 1969, § 38-175c was amended to require parity of [uninsured motorist] coverage with the minimum limits of liability coverage required by General Statutes § 14-112 (a). See Public Acts 1969, No. 202. In 1983, § 38-175c was again amended now to require parity of [uninsured motorist] coverage with the amount of liability coverage purchased by the insured unless the insured specifically requested a lesser amount. See Public Acts 1983, No. 83-461.” (Emphasis omitted.) Id., 402-403. We concluded that the recent history of the statute reveals: “(1) a heightened legislative interest in uninsured motorist protection; (2) a mandate to raise the amount of this protection; and (3) an intention to increase the public’s consciousness as to the availability of this kind of insurance by requiring increased coverage unless the insured specifically requested otherwise.” Id., 403. “A statute is to be construed by considering its legislative history, language, purpose and the circumstances surrounding its enactment.” (Internal quotation marks omitted.) Id. Accordingly, we must determine whether these factors, including the policies enumerated in Travelers Indemnity Co. v. Malec, supra, compel the conclusion that § 38-175c applies to personal excess policies, such as the policy involved in this case.
In discussing the relationship of uninsured motorist coverage to excess (or umbrella) policies, one leading commentator has stated: “Umbrella policies serve an important function in the industry. In this day of uncommon, but possible, enormous verdicts, they pick up this exceptional hazard at a small premium. Assuming one’s automobile and homeowner’s policies have [640]*640liability limits of $100,000 or even $500,000, the umbrella policy may pick up at that point and cover for an additional million, five million, or ten million. It may assume as a primary carrier certain coverages not included elsewhere . . .. but there is no intention to supplant the basic carriers on the homeowners or automobile coverages. . . . However, because of the misunderstanding of the courts as to the nature of such coverages, they have been held to fall within the definition of automobile liability insurance.” (Emphasis added.) 8C J. & J. Appleman, Insurance Law and Practice (1981) § 5071.65, p. 107.
We are persuaded that excess or umbrella policies, such as the policy issued to the Masses by USF&G, serve a purpose distinct from that served by policies that exclusively cover liability from damages arising out of the ownership, maintenance or operation of an automobile. While the Masses’ personal excess policy provides, among other coverages, coverage for automobile liability, this does not convert it into an “automobile liability policy” within the meaning of § 38-175c. Rather, the language of the personal excess policy indicates that it was intended as “excess insurance designed solely to protect [the Masses] from the infrequent occurrence of catastrophic judgments against [them].” (Emphasis added.) Trinity Universal Ins. Co. v. Metzger, 360 So. 2d 960, 962 (Ala. 1978).9
The personal excess policy issued to the Masses by USF&G did not expressly refer to uninsured motorist coverage. In addition, the record is devoid of evidence that the parties intended to include uninsured motor[641]*641ist coverage at the time they entered into the contract. Although the Masses did not explicitly waive uninsured motorist coverage under the excess policy; see footnote 6, supra; no premium for such coverage was paid to USF&G. In contrast, the Masses’ automobile insurance contract with USF&G specifically included a premium for uninsured motorist coverage. Moreover, while it is true that the excess policy did not expressly exclude uninsured motorist coverage, this omission does not create any ambiguity in light of other express terms limiting the policy to excess liability coverage. See Hartbarger v. Country Mutual Ins. Co., 107 Ill. App. 3d 391, 394, 437 N.E.2d 691 (1982). Because the Masses’ personal excess policy did not expressly provide uninsured motorist coverage, USF&G was under no obligation to exclude such coverage expressly.10 See Hammer v. Lumberman’s Mutual Casualty Co., 214 Conn. 573, 588-89, 573 A. 2d 699 (1990) (before need for exclusion arises, there must be coverage within defined scope of policy).
Mass argues, in essence, that uninsured motorist coverage should be provided under the personal excess policy for the premium the Masses paid for such coverage under the primary automobile insurance contract only. Although § 38-175e does not prohibit such a result, we decline to read it into the policy when the language of the policy does not clearly indicate an intent to pro[642]*642vide uninsured motorist coverage. See, e.g., Griswold v. Union Labor Life Ins. Co., 186 Conn. 507, 512, 442 A.2d 920 (1982) (determinative question in construing insurance contract is intent of parties, i.e., what coverage insured expected to receive and what insurer was to provide as disclosed by policy provisions). “It is obvious that the present [excess] policy was intended by both parties to protect the insured against excess judgments, and the risks and premiums were calculated accordingly. To require that policy to furnish uninsured motorist coverage would work a substantial revision of that policy.” Hartbarger v. Country Mutual Ins. Co., supra, 396.
Mass refers us to certain decisions in jurisdictions in which the courts have concluded that excess or umbrella policies are automobile liability policies that must provide uninsured motorist coverage. See, e.g., Aetna Casualty & Surety Co. v. Green, 327 So. 2d 65 (Fla. App.), cert. denied, 336 So. 2d 1179 (Fla. 1976); Southern American Ins. Co. v. Dobson, 441 So. 2d 1185 (La. 1983); Duriak v. Globe American Casualty Co., 28 Ohio St. 3d 70, 502 N.E.2d 620 (1986); Cincinnati Ins. Co. v. Siemens, 16 Ohio App. 3d 129, 474 N.E.2d 655 (1984). Mass argues that this court should adopt the reasoning of these cases because the applicable uninsured motorist statutes are similar to § 38-175c in that they require an insurer to provide uninsured motorist coverage in amounts equal to liability coverage. In other jurisdictions that have considered whether excess policies must provide uninsured motorist coverage pursuant to statute, however, courts have answered the question in the negative. See O’Hanlon v. Hartford Accident & Indemnity Co., 639 F.2d 1019, 1029 (3d Cir. 1981); Trinity Universal Ins. Co. v. Metzger, supra; Hartbarger v. Country Mutual Ins. Co., supra; United Services Automobile Assn. v. Wilkinson, 132 N.H. 439, 569 A.2d 749 (1989); Matarasso v. Continental Casualty Co., [643]*64382 App. Div. 2d 861, 440 N.Y.S.2d 40 (1981), aff'd, 56 N.Y.2d 264, 436 N.E.2d 1305, 451 N.Y.S.2d 703 (1982); Moser v. Liberty Mutual Ins. Co., 731 P.2d 406 (Okla. 1986); Thompson v. Grange Ins. Assn., 34 Wash. App. 151, 660 P.2d 307 (1983). Mass contends that these decisions are inapposite because the relevant statutes provide for minimum uninsured motorist coverage rather than uninsured motorist limits equal to liability limits, as does § 38-175c. But see United Services Automobile Assn. v. Wilkinson, supra.11 We are persuaded, nonetheless, that the reasoning of these latter cases applies to § 38-175c.12
In Matarasso v. Continental Casualty Co., supra, the insured sought uninsured motorist coverage under a “Commercial Umbrella Liability Policy” issued by the defendant insurance company. The umbrella policy protected the insured against claims by third parties in excess of the total applicable limits of liability of certain underlying liability policies, including an automobile liability policy. The umbrella policy, which incorporated [644]*644by reférence provisions of the underlying policies with respect to liability coverage, did not include an uninsured motorist endorsement or supplementary uninsured motorist coverage. In concluding that the uninsured motorist endorsement in the underlying automobile liability policy did not apply to the umbrella policy, the Appellate Division of the Supreme Court of New York stated: “The umbrella policy clearly provides excess protection for [the insured] and his business against liability from third party claims. It incorporates the underlying policies insofar as they provide for protection against liability for damages to third parties. The uninsured motorist coverage provided by the underlying automobile liability policy does not involve claims of liability against the insured from third parties and is not incorporated by the umbrella policy. Any other interpretation would distort the actual purpose of the umbrella policy. ” (Emphasis added.) Id., 862. The court held that New York’s uninsured motorist statute did not mandate uninsured motorist coverage in the umbrella policy because the umbrella policy was not an automobile liability policy within the meaning of the statute, but rather had been purchased to provide excess liability coverage for a variety of potential claims and had been issued upon underlying liability policies. The court concluded that the insured had received the protection of the uninsured motorist statute through his underlying automobile liability policy and, therefore, had not been left without relief. Id.
Trinity Universal Ins. Co. v. Metzger, supra, involved facts similar to those presented in Matarasso. In Trinity Universal Ins. Co., the insured’s executor sought uninsured motorist coverage under a “Personal Excess Umbrella Policy” that covered “ 'ultimate net loss in excess of the underlying limit which the insured shall become legally obligated to pay as damages because of personal injury or property damage.’ ” Id., 961. The [645]*645“underlying limit” referred to the limits on two underlying policies, including an automobile liability policy. In concluding that the state’s uninsured motorist statute13 did not require uninsured motorist coverage in the umbrella policy, the Alabama Supreme Court stated: “Automobile liability policies and motor vehicle liability policies insure against the risk of loss through the operation of specific automobiles. An umbrella policy, on the other hand, is fundamentally excess insurance designed to protect against catastrophic loss. Before an umbrella policy is issued, a primary policy (the ‘underlying policy’) must be in existence and this primary policy must by law provide uninsured motorist coverage. The umbrella policy assumes a risk of much less frequent occurrence, i.e., the risk of judgments in excess of primary policy limits, and accordingly carries premiums which reflect the lesser magnitude of this risk. The umbrella policy ... is an inherently different type of insurance from an automobile or motor vehicle liability policy, and consequently does not come within the scope of the uninsured motorist statute. ” (Emphasis added.) Id., 962.
In O’Hanlon v. Hartford Accident & Indemnity Co., supra, the plaintiff sought reformation of an umbrella policy, denominated a “Personal Catastrophe Plan,” which included automobile liability coverage up to the [646]*646statutory uninsured motorist limits of $300,000.14 The policy provided uninsured motorist coverage up to $35,000 after the deduction of a “retained limit.” The United States Court of Appeals for the Third Circuit concluded that Delaware’s uninsured motorist statute did not require the umbrella policy to provide uninsured motorist coverage equal to the statutory limits. The court stated: “Policies such as the [insurer’s] umbrella policy . . . with respect to their automobile coverages, would not exist but for underlying primary auto policies to which they provide excess liability insurance. Primary insurance policies ... by their very existence, provide insureds with all the benefits accorded under [the uninsured motorist statute]. To place umbrella policies within the ambit of [the uninsured motorist statute] would be to apply that section to [647]*647require [uninsured motorist] coverage in addition to that provided by primary policies. We do not believe that [the uninsured motorist statute] can be so read, and hold that it is not applicable to policies that provide excess liability insurance.” Id., 1027.
The reasoning of the courts in Matarasso, Trinity Universal Ins. Co. and O’Hanlon applies with equal force to the present case. The personal excess policy that the Masses purchased from USF&G would not have existed but for the underlying primary insurance policies listed in the declarations, including the automobile insurance contract. The underlying automobile insurance contract, which complied with the provisions of § 38-175c, provided the plaintiffs with all of the benefits accorded them pursuant to the statute.
Mass contends that the policy behind § 38-175c is “to ensure that insureds receive more than the bare minimum of [uninsured motorist] coverage in recognition of the often catastrophic consequences of automobile collisions and the gross inadequacy of statutory minimum coverages.” While we do not disagree with this contention, we believe that this policy is adequately served by the conclusion we reach in this case. The purpose of § 38-175c is to compensate an insured to the same extent as he would have been if he had been injured by a motorist carrying liability insurance equal to the coverage carried by the insured, unless the insured has elected in writing uninsured motorist coverage in an amount less than his liability coverage. In the present case, it is undisputed that Daniel and Jessica Mass and the estate of Sara Mass were compensated in an amount equal to the liability limits under the Masses’ automobile insurance contract with USF&G.15 [648]*648Accordingly, we are persuaded that the Masses received the full protection contemplated by the statute when they purchased the underlying automobile liability policy.16
USF&G also points us to § 38-175a-4 of the Regulations of Connecticut State Agencies in support of its argument that it was not required to provide uninsured motorist coverage to the Masses under the personal excess policy. Pursuant to General Statutes § 38-175a, the insurance commissioner has the authority to enact regulations governing uninsured motorist coverage. In enacting such regulations, however, the commissioner must effectuate the purpose and intent of the uninsured motorist statute. American Universal Ins. Co. v. DelGreco, 205 Conn. 178, 196, 530 A.2d 171 (1987). In accordance with his statutory authority, the commissioner has promulgated §§ 38-175a-1 through 38-175a-9 of the Regulations of Connecticut State Agencies, which define minimum provisions to be included in automobile liability insurance policies, including uninsured motorist coverage. Section 38-175a-4, entitled “Exceptions,” provides in relevant part: “These regulations do not apply to the insurance afforded under any policy . . . if the policy contains an underlying insurance requirement . . . .” (Emphasis added.)
Mass argues that § 38-175a-4 is not valid because it conflicts with the purpose and intent of General Stat[649]*649utes § 38-175c.17 We disagree. It is well established that “an administrative agency’s regulations are presumed valid and, unless they are shown to be inconsistent with the authorizing statute, they have the force and effect of a statute.” Travelers Ins. Co. v. Kulla, 216 Conn. 390, 399, 579 A.2d 525 (1990). Moreover, “[a] person claiming the invalidity of a regulation has the burden of proving that it is inconsistent with or beyond the legislative grant.” Id. Finally, the insurance commissioner has a “very broad grant of regulatory authority in filling in the interstices of the uninsured and underinsured motorist coverage legislation, and in doing so his regulation is entitled to great deference.” (Internal quotation marks omitted.) Id.; Roy v. Centennial Ins. Co., 171 Conn. 463, 473, 370 A.2d 1011 (1976). We are persuaded that § 38-175a-4 of the regulations is consistent with General Statutes § 38-175c. We therefore accord great deference to the commissioner’s interpretation that § 38-175c does not apply to policies, such as the policy involved in the present case, that contain an underlying insurance requirement.
Because the personal excess policy issued by USF&G to Norman and Sara Mass is not an automobile liability policy within the meaning of § 38-175c, the trial court properly concluded that the statute did not require the policy to provide uninsured motorist coverage. Therefore, the trial court properly determined that the total amount of uninsured motorist coverage available to the estate of Sara Mass and to Daniel and Jessica Mass was $1,000,000, pursuant to the automobile insurance contract. Our determination regarding this first claim disposes of Mass’ second claim that $3,000,000 in uninsured motorist coverage was available under the personal excess policy. In addition, [650]*650because § 38-175c (b) (1) limits USF&G’s liability to the amount of uninsured motorist coverage available; see footnote 3, supra; it is unnecessary to consider his third claim that the award to the estate of his wife was inadequate.
The judgment is affirmed.
In this opinion Shea, Covello and Borden, Js., concurred.
