delivered the opinion of the court:
The United States Court of Appeals for the 7th Circuit, pursuant to Circuit Rule 52 (Fed. R. App. P. 52), certified the following question of Illinois law to this court:
“Does Illinois law require insurers to offer underinsured motorist coverage (and, if so, in what amount) to automobile purchasers who opt for uninsured motorist coverage at the minimum statutory level?” DeGrand v. Motors Insurance Corp. (7th Cir. 1990), 903 F.2d 1100, 1104.
We accept jurisdiction to answer this question pursuant to Supreme Court Rule 20 (134 Ill. 2d R. 20).
. On February 8, 1986, Luke DeGrand and Karen Kies DeGrand purchased a 1986 Chevrolet Nova from Ruby Chevrolet in Chicago. They financed the vehicle through General Motors Acceptance Corporation (GMAC), a subsidiary of General Motors, engaged in the business of financing motor vehicles. The DeGrands applied for, and received, automobile insurance from Motors Insurance Corporation (MIC), a subsidiary of GMAC, engaged in the business of insuring motor-vehicle-related risks. All of this was accomplished before the DeGrands drove their new car from the Ruby Chevrolet lot.
On March 12, 1986, Karen Kies DeGrand was involved in an automobile accident. Karen sustained a severe and permanent ankle injury as a result of the two-car collision. The DeGrands sued the driver of the other car. Unfortunately, that driver carried only minimal bodily injury liability coverage ($50,000), which was insufficient to compensate Karen.
The DeGrands turned to their own automobile insurance policy to determine whether their policy covered excess damages. When they discovered it did not, they sued their insurer, MIC, in State court for reformation of their insurance contract, claiming MIC had violated Illinois law by failing to offer them underinsured motorist coverage in an amount equal to their bodily injury liability coverage.
The DeGrands filed a declaratory judgment action against MIC in the circuit court of Cook County (Ill. Rev. Stat. 1987, ch. 110, par. 2—701). Plaintiffs alleged that MIC failed to offer them an opportunity to purchase underinsured motorist coverage up to the limits of their bodily injury liability coverage in violation of section 143a—2 of the Illinois Insurance Code (Code) (Ill. Rev. Stat. 1987, ch. 73, par. 755a—2). The DeGrands also requested a judgment reforming their MIC policy to increase their underinsured coverage up to their bodily injury liability coverage ($100,000 per person/$300,000 per occurrence).
MIC removed the action to the United States District Court for the Northern District of Illinois based on diversity, pursuant to 28 U.S.C. §1332 (1988). Both the DeGrands and MIC filed cross-motions for summary judgment.
On June 14, 1989, the district court granted MIC summary judgment on the entire complaint because the policy of insurance was issued after July 1, 1983, and MIC was under no statutory duty to make an offer of underinsured motorist coverage. The DeGrands filed a notice of appeal.
On May 30, 1990, the 7th Circuit rendered its opinion (903 F.2d 1100), certifying to this court the question of law. The 7th Circuit recognized that “[t]he language of the statute does not seem to require insurers to issue or offer any underinsurance to drivers who elect minimum uninsured motorist coverage.” (Emphasis in original.) (903 F.2d at 1103 n.2.) The 7th Circuit noted that there was a split of authority in the districts of the appellate court of Illinois.
The DeGrand’s insurance policy provided bodily injury and property damage coverage of $100,000 per person and $300,000 per occurrence. The policy also provided uninsured motorist coverage of $15,000 per person and $30,000 per occurrence, and although allegedly unknown to the DeGrands, underinsured motorist coverage in the same amount as uninsured. The DeGrands claimed they never knew about the underinsured motorist coverage until after the accident.
The only dispute between the DeGrands and MIC is relative to underinsured motorist coverage. There is no question, however, that the DeGrands had sufficient knowledge of their uninsured motorist coverage. Luke DeGrand’s signature appears underneath the text referring to an opportunity to purchase coverage up to the bodily injury limits. In a blocked section above the signature block, the word “underinsurance” appears in the MIC printed insurance application which refers to the amount of coverage for uninsured/underinsured liability. All of the printing on the insurance application is the same size. The application provides, in part:
“I apply for the following liability limits:
Bodily injury and property damages — limit %100 300,000
Uninsured/underinsured motorist coverage
_ A equal to liability limits selected above
x B other (specify) 15/30.
Limits for uninsured/underinsured motorist coverage may not exceed limits for bodily injury and property damage coverages.
* * *
I acknowledge that I have been provided an opportunity to purchase uninsured motorist coverage up to the limits of my bodily injury limits.
s/Luke DeGrand”
(Emphasis added.)
Although the policy application provides coverage for underinsurance in the same amount as uninsured coverage, plaintiffs argue that MIC’s failure to offer them underinsurance coverage constitutes a breach of its legal responsibilities under the Code. MIC argues that recent amendments to the Code make such an offer unnecessary because when an individual elects uninsured motorist coverage, the individual automatically receives under-insurance in the equivalent amount, so long as the policy contains such provisions. The policy application in this cause contained such a provision.
The district court, in reiterating MIC’s position, stated:
“Because plaintiffs’ insurance policy provided uninsured motorist coverage at the minimum limit, MIC was under no statutory duty to make an offer of underinsured motorist coverage. As of July 1, 1983, an insurer’s obligation to include — not merely offer — underinsured motorist coverage turns on whether the policy provides for uninsured motorist coverage in excess of the statutory minimum. Since plaintiffs’ policy was issued after July 1, 1983, and provided uninsured motorist coverage only at the statutory minimum level, their claim against MIC must fail.”
In conclusion, the district court held that the Code did not require insurers to offer additional underinsured motorist coverage when individuals elect uninsured motorist coverage at the statutory minimum.
In light of the certified question, this court finds that the focus of this matter is one of statutory interpretation. Since this is a diversity case, such focus is proper. (Cf. United States v. Thirty-Seven (37) Photographs (1971), 402 U.S. 363, 369, 28 L. Ed. 2d 822, 829-30, 91 S. Ct. 1400, 1404-05.) Only a State court can authoritatively interpret its own State’s statutes and ordinances. Waldron v. McAtee (7th Cir. 1983), 723 F.2d 1348, 1352.
It is well established that in construing a statute, the court should give effect to the legislative intent. (State v. Mikusch (1990), 138 Ill. 2d 242.)
“In seeking to ascertain legislative intent, courts consider the statutes in their entirety, noting the subject they address and the legislature’s apparent objective in enacting them. [Citation.] It is presumed that the legislature, in enacting various statutes, acts rationally and with full knowledge of all previous enactments. [Citation.]” (Mikusch, 138 Ill. 2d at 247-48.)
The court stated further:
“Generally, a material change in the language of an unambiguous statute creates a presumption, although it can be rebutted by evidence of a contrary legislative intent, that the amendment was intended to change the law. [Citations.]” 138 Ill. 2d at 252.
Prior to August 16, 1982, section 143a—2 stated, in part:
“(1) Required offer of additional uninsured motor vehicle coverage. No policy insuring against loss resulting from liability imposed by law for bodily injury or death suffered by any person arising out of the ownership, maintenance or use of a motor vehicle shall be renewed or delivered or issued for delivery in State with respect to any motor vehicle registered or principally garaged in this State unless uninsured motorist coverage as required in Section 143(a) of this Act is offered in an amount wp to the insured’s bodily injury liability limits.
* * *
(3) Required offer of underinsured motorist coverage. Any offer made under subsection (1) of this Section shall also include an offer of underinsured coverage.” (Emphasis added.) Ill. Rev. Stat. 1981, ch. 73, par. 755a—2.
Under the 1981 statutory scheme, the insurer was required to make a meaningful offer of underinsured motorist coverage that could then be accepted or rejected by each insured individual. Cloninger v. National General Insurance Co. (1985), 109 Ill. 2d 419, 429.
In 1982, the legislature altered that scheme by amending the 1981 statute in Public Act 82 — 920, effective August 16, 1982, which provided, in part:
“(1) Required offer of additional uninsured motor vehicle coverage. No policy insuring against loss resulting from liability imposed by law for bodily injury or death suffered by any person arising out of the ownership, maintenance or use of a motor vehicle shall he renewed or delivered or issued for delivery in State with respect to any motor vehicle registered or principally garaged in this State unless uninsured motorist coverage as required in Section 143a of this Act is offered in an amount up to the insured’s bodily injury liability limits.
* * *
(3) Required offer of underinsured motorist coverage. Until July 1, 1983, any offer made under subsection (1) of this Section shall also include an offer of underinsured motorist coverage. ***
* * *
(5) On or after July 1, 1983, no policy insuring against loss resulting from liability imposed by law for bodily injury or death suffered by any person arising out of the ownership, maintenance or use of a motor vehicle shall be renewed or delivered or issued for delivery in this State with respect to any motor vehicle registered or principally garaged in this State unless underinsured motorist coverage is included in such policy in an amount at least equal to the total amount of uninsured motorist coverage provided in that policy where such uninsured motorist coverage exceeds the limits set forth in Section 7—203 of the Illinois Vehicle Code.” (Emphasis added.) Ill. Rev. Stat. 1983, ch. 73, pars. 755a—2(1), (3), (5).
These 1982 amendments were in effect until the legislature changed that scheme in Public Act 86—1156, section 4, effective August 10, 1990, and Public Act 86—1155, section 1, effective July 1, 1991 (hereinafter referred to as the 1990 statute). The 1990 statute provides in part, with emphasis added to the new language:
“(1) Additional uninsured motor vehicle coverage. No policy insuring against loss resulting from liability imposed by law for bodily injury or death suffered by any person arising out of the ownership, maintenance or use of a motor vehicle shall be renewed or delivered or issued for delivery in this State with respect to any motor vehicle designed for use on public highways and required to be registered in this State unless uninsured motorist coverage as required in Section 143a of this Code is included in an amount equal to the insured’s bodily injury liability limits unless specifically rejected by the insured. Each insurance company providing the coverage must provide applicants with a brief description of the coverage and advise them of their right to reject the coverage in excess of the limits set forth in Section 7—208 of The Illinois Vehicle Code. The provisions of this amendatory Act of 1990 apply to policies of insurance applied for after June 80, 1991.
* * *
(3) The original application indicating the applicant’s selection of uninsured motorist coverage limits shall constitute sufficient evidence of the applicant’s selection of uninsured motorist coverage limits and shall be binding on all persons insured under the policy. ***
^ * * *
On or after July 1, 1983, no policy insuring against loss resulting from liability imposed by law for bodily injury or death suffered by any person arising out of the ownership, maintenance or use of a motor vehicle shall be renewed or delivered or issued for delivery in this State with respect to any motor vehicle designed for use on public highways and required to be registered in this State unless underinsured motorist coverage is included in such policy in an amount equal to the total amount of uninsured motorist coverage provided in that policy where such uninsured motorist coverage exceeds the limits set forth in Section 7—203 of the Illinois Vehicle Code.” (Emphasis added.) Ill. Rev. Stat., 1990 Supp., ch. 73, pars. 755a—2(1), (3), (4).
We now turn to the interpretation of those amendments. In the 1981 statute, the insurer was required to make a meaningful offer of underinsured motorist coverage that could be accepted or rejected by each insured individual. However, the legislature substantially altered that scheme with the 1982 statute.
The 1982 statute provided that whenever an individual purchased uninsured motorist coverage in an amount greater than the statutory minimum, the insurer must also provide underinsured motorist coverage in the same amount. The 1982 statute also provided that after July 1, 1983, the insurer must provide and the insured must accept the underinsured motorist coverage. The new statute did not permit the insurer or insured to reject this coverage. The 1982 statute provided additional coverage for many individuals purchasing automobile insurance after July 1, 1983. If the insured purchased uninsured motorist coverage in an amount above the statutory minimum, the insured must also purchase underinsured motorist coverage in the same amount.
The 1982 statutory scheme is consistent with the legislature’s purpose in enacting the 1981 statute as stated by this court in Cloninger v. National General Insurance Co. (1985), 109 Ill. 2d 419:
“[T]he legislature recognized that soaring medical costs often left injured parties only partially compensated for their injuries. The legislature was obviously concerned with adequately compensating injured parties.” Cloninger, 109 Ill. 2d at 424.
According to the 1982 statutory scheme, an automobile owner who purchases the minimum amount of uninsured motorist coverage after July 1, 1983, was entitled neither to an offer of underinsured motorist coverage nor to automatic inclusion of such coverage in an amount commensurate with uninsured motorist coverage provided the uninsured motorist coverage exceeded the statutory minimum. The policy had to contain underinsured motorist coverage in an amount at least equal to the total amount of uninsured motorist coverage. Only those policies issued prior to July 1, 1983, were entitled to an offer of underinsurance. The legislative history does not shed light on the reasons for the change. Furthermore, we agree with the district court that the parties to this appeal do not offer cogent reasons why the legislature would have adopted this course.
By 1990, the legislature had again changed the statutory scheme. In the amended statute, the legislature deleted the required offer of additional uninsured motor vehicle coverage. (Ill. Rev. Stat., 1990 Supp., ch. 73, par. 755a—2(1).) The 1990 statutory scheme provides that uninsured motor vehicle coverage must be in an amount equal to the insured’s bodily injury liability; whereas, the 1981 version required only an offer of uninsured motorist coverage in an amount up to the insured’s bodily injury liability limits. The 1982 statute provided only for a required offer for policies issued before July 1, 1983. (Ill. Rev. Stat. 1983, ch. 73, par. 755a—2(3).) The 1982 statutory scheme also provided that the underinsured motorist coverage be in an amount at least equal to the total amount of uninsured motorist coverage. Ill. Rev. Stat. 1983, ch. 73, par. 755a—2(5).
The 1990 statute adds a new element to the policies. The new provision provides that the insurer describe the coverage and advise the insured of his or her right to reject the coverage in excess of $20,000 per person/ $40,000 per occurrence. (Ill. Rev. Stat., 1990 Supp., ch. 73, par. 755a—2(1).) The statute also provides that the original or a copy of the policy shall constitute sufficient evidence of the insured’s selection of uninsured motorist coverage limits. (Ill. Rev. Stat., 1990 Supp., ch. 73, par. 755a—2(3).) The new scheme further provides that the underinsurance motorist coverage be in an amount equal to the total of uninsured motorist coverage as long as that coverage exceeds $20,000 per person/$40,000 per occurrence. See Ill. Rev. Stat., 1990 Supp., ch. 73, par. 755a—2(4).
In reading the statute and its amendments, this court finds that when the legislature enacted the change to the 1981 statutory scheme in 1982, the legislature acted rationally with full knowledge of all previous enactments as well as decisions. Furthermore, this court finds that the material change in the 1982 statute created a presumption that the amendment was intended to change the law regarding “required offer.” The 1990 statute supports that presumption. We hold that the insurer in this case was not required to make a specific offer of underinsured motorist coverage. We note that the policy did contain the words “underinsured and uninsured” in a section above the section which contained the insured’s signature. Although the print is small, the words are nonetheless in the application. This court also notes that the blocked section containing the words “uninsured/ underinsured” motorist coverage reveals that the minimum statutory coverage was specifically chosen because the box for “other” type coverage is marked with an X and the amount chosen, 15/30, is handwritten.
Plaintiffs argue that the policy behind the statute is that consumers must be made aware of this important type of coverage. In their argument, they state that the meaningful offer has been relocated. However, our reading of the statute and its subsequent amendments does not permit this interpretation. The 1990 statute provides proof that the insured must be made aware of the coverage but the “meaningful offer” requirement has intentionally been removed. The 1990 statute significantly coincides with the legislative scheme to protect the insured/consumer by making uninsured and underinsured motorist coverage equal and mandatory. We cannot find where the meaningful offer requirement has been “relocated.”
Plaintiffs cite Cloninger v. National General Insurance Co. (1985), 109 Ill. 2d 419, for support of their argument that the amount of coverage for underinsured motorist coverage should equal the insured’s bodily injury liability limits. However, we find Cloninger distinguishable.
In Cloninger, the policy was issued prior to the 1982 statute and as such the governing statute was the 1981 version. More importantly, the issue before the Cloninger court was not whether an offer must be made but rather whether an offer was made and whether that offer was made in a commercially reasonable manner. The Cloninger court found:
“The legislature not only required that underinsuredmotorist coverage be offered but also provided that the insured had a right to elect or reject such coverage. [Citation.] The right to elect or reject such coverage requires that the insured have information regarding the coverage. [Citation.] Therefore, we believe that the legislature intended that the ‘offer’ mandated in section 143a—2(3) provide the insured with enough information regarding underinsured-motorist coverage to allow the insured to make an intelligent decision of whether such coverage should be elected or rejected. Such an intelligent decision cannot be made unless an explanation of the coverage is supplied. [Citation.]” Cloninger, 109 Ill. 2d at 424-25.
When this court held in Cloninger that the insurer must explain the coverage, we adopted the four-point test for commercial reasonableness of an offer established by the Minnesota Supreme Court in Hastings v. United Pacific Insurance Co. (Minn. 1982), 318 N.W.2d 849. Although the holding in Cloninger dealt with the 1981 version of the statute, part of that holding is still viable, but not the meaningful offer test. The 1990 statute provides an explanation of coverage by the insurer as follows:
“Each insurance company providing the coverage must provide applicants with a brief description of the coverage and advise them of their right to reject the coverage in excess of the limits set forth in Section 7—203 of The Illinois Vehicle Code.” Ill. Rev. Stat., 1990 Supp., ch. 73, par. 755a—2(1).
We note that since Cloninger, the legislature has avoided the use of the term “required offer” in the statute. In fact, we find that the 1990 statute places the burden on the insured to reject and subsequently to reduce the uninsured motorist coverage which is automatically set at an amount equal to the bodily injury liability. No longer is the insurer responsible to make an offer, but rather it is the insured’s duty to reduce the uninsured motorist coverage. Furthermore, whatever uninsured motorist coverage the insured elects, underinsured motorist coverage will be set, mandatorily, at the uninsured motorist coverage level. At that point, it is the duty of the insurer to explain the coverage and nothing more. The 1990 statute eliminated the need for the Hastings four-point test for determining whether the offer was made in a commercially reasonable manner, as adopted in Cloninger.
The dissent asserts that the opinion of this court did not adequately address the certified question and that this court did not accurately interpret the statutory intent. We do not agree. This court notes that, first, the parties failed to provide adequate reasons for their interpretation of the statute and second, we, like the Federal court, did not find that the legislative history, i.e., hearings and debate, did not provide any assistance. Therefore, this court reviewed the next best source of information. This court took into account all of the numerous and drastic statutory changes which took place over a very short period of time. Those changes provide the best source of information and evidence regarding statutory intent. It is from that entire history that we reached the result in this opinion.
We did not focus on one senator’s remarks or one statutory change but a series of drastic changes to one section of the Insurance Code over a short period of time. It is through those observations that this court concluded that the meaningful offer test is not applicable.
Furthermore, this court reviewed those changes to the statute in light of the entire insurance application at issue. We did not focus on only one section of the application. The dissent, however, focuses on the fact that the car salesperson filled out the application and as such asserts that the majority has failed to protect the consumer by finding that the meaningful offer test is not applicable. However, this court finds otherwise. This court recognizes that the consumer in this instance unfortunately may have been placed at a disadvantage; nevertheless, it does not circumvent our duty to interpret the statute as reflected in the statutory changes. Thus, this court cannot increase the protection of a statute without more evidence of such intent. Furthermore, this court notes that the legislature had taken notice of the unfortunate situation and incorporated changes to the statute to reflect those concerns. Consequently, the legislature enacted the present statute.
Thus, we find that the 1982 statute did not require insurers to offer underinsured motorist coverage to automobile purchasers who opted for uninsured motorist coverage at the minimum statutory level.
Certified question answered.
