Utica Mutual Insurance Company (Utica) seeks a judgment declaring that it is not obligated under its commercial-umbrella liability policy to provide underinsured motorist (UIM) coverage to its insured. Based on the unique facts present in this case, the trial court found that Utica is so obligated. A divided panel of the Appellate Division affirmed in an unreported opinion. Utica appeals to this Court as of right. See R. 2:2-1(a)(2).
I
The facts dictate our resolution of this appeal. The matter arises in the context of cross-motions for summary judgment and all parties agree that no genuine issue of material fact exists. In 1983, Sarasohn & Company (Sarasohn) purchased two insurance *547 policies from defendant Utica. The policies were obtained through defendant Anthony Russo, a broker with defendant Russo Insurance Agency, Inc. (Russo). One of the policies was an automobile policy providing $750,000 in liability coverage as well as uninsured motorist (UM) and UIM coverage of $500,000 and $1,000,000. The other was a special multi-peril policy -with a $4,000,000 limit. When the $4,000,000 multi-peril policy was to be renewed in August 1986, Utica informed Russo that it would not continue to offer that policy. In place of the multi-peril policy, Utica offered to write a primary-liability policy with a $1,000,000 limit and a $3,000,000 commercial-umbrella liability policy. The $3,000,000 umbrella policy would provide expanded coverage beyond the limits set forth in the automobile policy.
Russo presented the policy to Sarasohn, seeking the “approval to go ahead and do it that way.” In a letter dated August 26, 1986, Sarasohn authorized Russo to obtain the umbrella policy from Utica. Moreover, Sarasohn confirmed its understanding that the policy would provide $3,000,000 in coverage above the auto-policy coverage.
Utica initially issued the umbrella policy in August 1986. The umbrella policy provided that the insurer shall “pay on behalf of the insured all sums ... [that] the insured shall become legally obligated to pay,” for personal injury, property damage, and other specified consequences caused by an occurrence during the policy period. Utica’s Underwriting Procedures Manual stated that “[b]ecause the Utica Mutual umbrella policy is such a broad contract, the Company and its reinsurers must be protected with adequate underlying coverages,” and therefore the “[underlying insurance for automobile liability ... must be written” by Utica. (Emphasis omitted).
Utica had an umbrella treaty arrangement with General Reinsurance Corporation (General Reinsurance), in which Utica reinsured with General Reinsurance the umbrella policy and “retained] a portion of the premium and coverages and Reinsurance all the rest of it.” As the umbrella policy was nearing renewal in *548 August 1987, General Reinsurance informed Utica senior underwriter Sandra Burleigh on July 22,1987, that it would not provide UM and UIM coverage in the renewal umbrella policy unless the UM/UIM limits in the underlying auto policy were increased to match the liability limits in the auto policy. At that time, the underlying auto policy contained liability coverage in the amount of $750,000 and UM/UIM coverage of $500,000. The substance of that conversation was confirmed in a subsequent letter from General Reinsurance to Utica dated September 14, 1987, which stated, “It is understood that we will exclude ... UM if the limits are not increased to equal the [automobile liability].”
Pursuant to the “instructions from [the] umbrella carrier [that] specified [that Utica] had to have specific underlying limits on [the] primary policies to meet the underwriting requirements,” Burleigh informed Russo in a memorandum dated July 23, 1987, that “to meet the umbrella carrier’s requirements, the UM limit must be increased to equal the liability limit. An endorsement has been processed effective] 8/11/87 making this change.” In turn, Russo apparently informed Sarasohn of the required $250,000 increase in the limits of the UM/UIM coverage for the underlying automobile policy. Sarasohn accepted the change, and paid an additional premium.
Russo did not “know of any other reason” for raising the limits of UM/UIM coverage in the underlying policy except to provide for UM/UIM coverage in the umbrella policy. Russo understood “that the umbrella policy had requirements on limits of underlying insurance, and the umbrella requirement was now seven hundred fifty thousand for uninsured motorist, in order that uninsured motorist coverage on the excess would be applicable.” Russo believed that at the time the UM/UIM policy limits were raised, the umbrella policy included UM and UIM coverage.
When the umbrella policy was renewed in August 1987, Utica had available an endorsement, form 8-UMB-14, that excluded UM and UIM coverage from umbrella policies. That endorsement stated that “the insurance provided by this [umbrella] policy shall *549 not apply to sums which the Insured shall be legally entitled to recover as damages from the owner or operator of ... an underinsured automobile because of personal injury sustained by the Insured.” Utica’s Underwriting Procedures Manual provided: “This endorsement should be used (1) if insured elects not to have uninsured motorists coverage in the umbrella policy or (2) if insured’s uninsured motorists limits on the underlying auto policy do not equal the policy’s BI limits.” Endorsement 8-UMB-14 was not attached to the umbrella policy purchased by Sarasohn.
Plaintiff Gerard Doto (Doto) was an employee of Sarasohn and was a named insured under his employer’s commercial-automobile liability policy. On April 18,1988, Doto was injured as a pedestrian in an automobile accident while in the course of company business, and incurred substantial medical expenses in excess of $750,000. Doto filed suit against the driver of the automobile, whose automobile-liability policy provided coverage in the amount of $250,000. Because the UIM coverage afforded Doto under his employer’s policy was greater than the liability limits of the policy held by the driver, Doto initiated a claim for UIM benefits under the automobile policy issued by Utica in which he was a named insured. See N.J.S.A. 17:28-1.le. Doto recovered $500,000, the full UIM coverage available under the automobile policy issued by Utica less the amount of liability insurance available under the driver’s policy.
Doto’s medical expenses exceeded the amounts recovered from the driver’s policy and from Utica’s UIM coverage under the automobile policy. In a letter dated March 19, 1990, to Gary LaRouche, the Utica District Claims Manager, Russo stated: “The insured has requested that we extend his under insured motorist claim into the umbrella liability policy. I have read the policy and can’t see where his claim is excluded.” While awaiting a response from LaRouche, Russo contacted various persons within Utica in an attempt to verify that the umbrella policy included UM/UIM coverage. Richard Gaffney of Utica’s Errors and Omissions Department, whom Russo initially had contacted *550 about the claim for UIM coverage under the umbrella policy, allegedly had informed Russo in either 1989 or 1990 “that it’s covered unless there [wa]s an exclusion endorsement.” Gaffney’s representation was apparently verified by Cheryl DePaul, a Utica underwriter, who had informed Gaffney that “our commercial umbrella policy does not exclude UM/UIM unless we attach an 8-UMB-14 endorsement.”
Russo also contacted Bruce Hall, a Utica executive involved in underwriting commercial policies. On July 17, 1991, Russo telephoned Hall, telling him that he “also needs [a] statement that we are covering uninsured/underinsured motorist coverage.” Hall told Russo that he would “send [a] letter stating [that] we haven’t excluded the coverage from our umbrella.” On the same day, Russo sent a letter to Hall, stating, “This will confirm our phone conversation of today in which you advised me that the umbrella liability policy does in fact cover $3,000,000. excess uninsured and underinsured motorist coverage.”
On August 1, 1991, Russo again telephoned Hall, who informed Russo that “there was coverage on the umbrella policy ... [b]ased on the fact [Utica] did not ... put an endorsement on it excluding the coverage.” Hall confirmed the contents of that conversation in a letter to Russo, also dated August 1, 1991, stating: “Per our conversation, we have not excluded uninsured and underinsured motorist coverage from our policy. Therefore, if it is covered on the primary [automobile policy] it should be covered on the [umbrella].” Hall indicated that he would not have sent the letter dated August 1, 1991, confirming UM/UIM coverage under the umbrella policy to Russo without his supervisor, Cheryl DePaul, having “agreed with [my] interpretation at the time.” DePaul agreed that “if the underlying UIM limits match the underlying primary limits that the umbrella policy could be interpreted to include UIM coverage,” implying that if Utica had intended to exclude UIM coverage it would have attached endorsement 8-UMB-14 “to make it expressly clear that UIM coverage was not going to be included in the umbrella [policy].”
*551 Approximately one-and-one-half years after Russo’s initial inquiry, LaRouche informed Russo in a letter dated September 17, 1991, that “[w]e regret to advise you that we cannot honor your claim, as the [umbrella] policy in question, does not provide underinsured motorist coverage in this state.” In a complaint filed October 1991, Doto brought suit against Russo, alleging professional negligence in failing to procure an umbrella policy that included UM7UIM coverage. Additionally, Doto sought a declaratory judgment against Utica to determine his right to recover UIM coverage under the umbrella policy. Russo answered the complaint and filed a cross-claim against Utica demanding judgment “[declaring that plaintiff, Gerard Doto, is entitled to Underinsured Motorist Coverage under Utica Mutual Insurance [umbrella policy].” In June 1993, Russo' moved for summary judgment declaring that the “Utica umbrella policy in issue includes underinsured motorist coverage.” Doto joined in that application. Utica filed a cross-motion for summary judgment on the same issue.
The trial court granted summary judgment in favor of Russo and Doto, holding that the conduct of the insurance company, its agent, and the insured, both before writing the policy and after the accident, indicated that all parties had considered the umbrella policy to include UM/UIM coverage.
In affirming, the Appellate Division majority emphasized that specific, cumulative circumstances supported the determination that the umbrella policy provided UM coverage: “[T]he reinsurer of the umbrella policy required an increase in primary UM[/UIM] limits to equal the liability limit or else UMI7UIM] would be excluded; the primary UMI7UIM] limits were increased to equal the liability limit; and there was no endorsement excluding UM1/UIM] coverage from the umbrella policy.” The majority noted that “the conduct of Utica both before and after the accident is consistent with this conclusion.” The dissenting member asserted that an “umbrella policy is purely and simply a liability policy,” and that the majority’s ruling could not properly rest “on *552 the basis of the insignificant and idiosyncratic communications involved here.”

Both the dissenting member of the Appellate Division and Utica emphasize that umbrella policies characteristically do not contain UM/UIM coverage. Because umbrella policies are intended simply to provide comprehensive excess liability coverage, the purpose of umbrella coverage “is fundamentally different from a primary [automobile-] liability policy,”

643, 653,
Courts have recognized the unique characteristics of umbrella policies in resolving whether such policies are mandated by the
*553
UM statute enacted in their jurisdiction to include UM/UIM coverage. In states such as New Jersey that statutorily require only “minimum levels” of UM/UIM coverage,
see N.J.S.A
39:6A-14, although the insured may elect to purchase greater coverage up to a defined level,
see N.J.S.A.
17:28-1.1b, courts have generally subscribed to the view that umbrella policies do not provide UM/UIM coverage. While acknowledging “that there is a general public policy underlying the UIM statute of increasing and broadening the public’s protection against automobile accidents,”
MacKenzie v. Empire Ins. Cos.,
On the other hand, those states that require that the insurer provide UM/UIM coverage equal to automobile-liability coverage have determined that umbrella policies that provide excess-liability coverage must therefore provide equal UM/UIM coverage.

As a general matter, Utica correctly asserts that umbrella policies serve a purpose qualitatively different from UM/UIM coverage. In the absence of a requirement pursuant to a UM statute that UM/UIM coverage be equal to liability coverage, the general rule appears to be that umbrella policies should not be understood to provide UM/UIM coverage. However, other principles of insurance law influence our disposition of this appeal.

Nor have we permitted insurance companies to seek refuge in the literal language of their policies when the company’s conduct and actions, or that of their agents, causes the insured to act or to fail to act based on that conduct.

That General Reinsurance, the company with which Utica reinsured the umbrella policy, assumed the umbrella policy provided UM/UIM coverage is indisputable. General Reinsurance insisted that the UM/UIM coverage limits in the underlying liability policy be increased solely for the purpose of reducing its exposure to UM/UIM claims under the umbrella policy. Equally plain is that Utica also assumed that its umbrella policy provided UM/UIM coverage. No other explanation could justify Utica’s communication to Russo, Sarasohn’s agent, insisting that the UM/UIM limits in the underlying liability policy be increased and informing him that the necessary endorsement had already been processed.
No party contests the fact that Russo then informed Sarasohn of the necessary increase in the limits of the UM/UIM coverage for the underlying auto policy and that Sarasohn accepted the change and paid an additional premium. The only reasonable inference supported by the record is that Sarasohn paid the additional premium because the reinsurer and Utica had insisted that the added coverage was a prerequisite to Sarasohn’s securing UM/UIM coverage in the umbrella policy as well as in the underlying automotive • Ycy. “Indeed, if he was not so covered what justification could the company fairly advance for having taken that ... sum from him....”

Of less significance, but nevertheless relevant to the issue of the parties’ assumptions and expectations about the scope of coverage, is the fact that after the accident several Utica employees confirmed that the umbrella policy contained UM/UIM coverage. Assurances to Russo from numerous Utica employees that the umbrella policy provided UM/UIM coverage would perhaps be insignificant if the policy specifically excluded such coverage, and no course of conduct had occurred in connection with the policy’s issuance suggesting that the coverage existed. But in the context of this record, the affirmation by several knowledgeable Utica executives that UM/UIM coverage was included in Sarasohn’s umbrella policy assumes added weight, in effect reinforcing the evidence suggesting that General Reinsurance and Utica, prior to the accident, regarded the umbrella policy as providing UM/UIM coverage.
Moreover, Utica possessed a form designed for the express purpose of excluding the provision of UM/UIM coverage in the umbrella policy. An exclusion clause serves the purpose of delimiting and restricting coverage.
Capece v. Allstate Ins. Co.,
88
N.J.Super.
535, 541,
Utica asserted for the first time that the umbrella policy did not contain UM/UIM coverage in September 1991, over three years after the accident occurred. We are persuaded, based on the circumstances evident in the record, that Utica is estopped from denying coverage. Utica pursued a course of conduct during the renewal of the umbrella policy in August 1987 that would have convinced an objectively reasonable insured to believe that the umbrella policy contained UM/UIM coverage. In effect, Utica told Sarasohn’s agent that the umbrella policy would
not
provide UM/UIM coverage
unless
the UM/UIM limits in the underlying policy were raised. Abiding by that instruction, Sarasohn authorized the increased limits and paid the higher premium. Consequently, Sarasohn must have understood that the umbrella policy included UM/UIM coverage. That impression was confirmed by the post-accident representations and assurances by several Utica employees that the umbrella policy provided such coverage. “It is clear that a carrier who has issued a policy, by its later conduct may, for equitable reasons, be refused the right to assert an exclusion or the absence of specific coverage.”
