delivered the opinion of the court:
Plaintiff Maryland Casualty Co. (Maryland) appeals from a summary judgment granted to defendant Chicago and North Western Transportation Co. (C&NW) in a declaratory judgment action, whereby Maryland was found obligated to both defend and indemnify C&NW in a separate negligence action brought against C&NW by an employee of C&NW’s lessee, Demos News, Inc. (Demos).
This appeal raises as issues whether: (1) Maryland has a duty to defend C&NW in the negligence action under the terms of its general liability insurance policy issued to Demos; (2) Maryland has a duty to defend C&NW under the terms of an excess coverage policy issued to Demos; and (3) the circuit court erred by prematurely determining Maryland’s duty to indemnify C&NW.
Under a five-year lease dated July 1, 1978, Demos leased from C&NW three separate newsstand sites and other storage and office areas located in C&NW’s Chicago passenger terminal. Demos obtained from Maryland a comprehensive general liability policy (CGL), revised effective March 1, 1979, to include C&NW as “additional insured.” The excess coverage policy, called “Checkmate,” named only Demos as the insured.
Shortly after 5 a.m. on October 19, 1979, a Demos newsstand employee arrived at the passenger terminal to begin work. When she got to about 10 feet from her employer’s office door, a man grabbed her around the neck from behind and led her back to a stairwell, where they both fell down the stairs. She was knocked unconscious. She regained consciousness and discovered that she was naked from the waist down, had been raped, and was covered with blood. The victim suffered lacerations of the chin and lip, a fractured nose and cheekbone, numerous bruises and numbness in her teeth. She experienced deafness in her left ear for a period of six months. Her attacker was never apprehended.
The victim subsequently initiated an action against C&NW, alleging that her attack and resulting injuries had been proximately caused by C&NW’s negligence in controlling and maintaining the passenger terminal. C&NW tendered the defense of this suit to Maryland, which assumed the defense under a reservation of rights.
Maryland initiated the instant declaratory judgment action on April 26, 1982, seeking a determination of its rights and obligations with respect to the defense and indemnification of C&NW in the underlying action. Maryland filed a motion for summary judgment followed by C&NW’s cross-motion for the same relief. On March 1, 1983, the circuit court granted C&NW’s and denied Maryland’s motion, “finding the *** [CGL] policy covers the defense and potential indemnification” of C&NW as to the underlying action. Maryland’s motion for rehearing and stay were denied, and this appeal followed.
I
Maryland contends that the provisions of the CGL policy preclude any defense obligations to C&NW. Where the complaint alleges facts suggesting that coverage potentially exists, the duty to defend arises. (Maryland Casualty Co. v. Peppers (1976),
Insurance policy terms must be read according to their plain and ordinary meanings; any ambiguities arising when several provisions of the policy are read together will be construed in favor of the insured. (United States Fire Insurance Co. v. Schnackenberg (1981),
C&NW also relies on an endorsement (G222) to the policy which defines “insured premises” to include “the ways immediately adjoining on land.” This provision appears in the “additional definitions” portion of the policy designated “premises medical payments coverage,” for which the limit of liability is $1,000; by contrast, the “additional definitions” section of the “personal injury and advertising injury liability coverage,” for which the liability limit is $300,000, contains no such language. Clearly, the subject definition applies only to coverage for specific medical expenses. At the hearing on the cross-motions for summary judgment, the circuit court requested this language be read into the record. In ruling on the motions, the court stated: “Specifically, I find the occurrence in question took place 'on the ways immediately adjoining the land’ leased to [Demos] ***.” The principal basis for the circuit court’s decision is therefore misplaced.
The propriety of granting summary judgment to C&NW, in our opinion, turns on whether the attack on the victim arose “out of the ownership, maintenance or use” of the designated leased premises. Maryland maintains that the attack, occurring before the victim had begun work, did not arise from her employer’s use of the premises but from her mere presence in the terminal, which was open to the public. The phrase “arising out of” is both broad and vague, and must be liberally construed in favor of the insured; accordingly, “but for” causation, not necessarily proximate causation, satisfies this language. (Consolidated Rail Corp. v. Liberty Mutual Insurance Co. (1981),
The parties each cite cases construing the “arising out of” language in analogous contexts. Maryland relies principally upon National Hills Shopping Center, Inc. v. Liberty Mutual Insurance Co. (5th Cir. 1977),
C&NW cites Consolidated Rail Corp. v. Liberty Mutual Insurance Co. (1981),
None of the cases cited thus involved a situation closely paralleling that presented here: injuries caused by the alleged negligence of an additional insured under a liability policy and sustained by the employee of the named insured, immediately outside the leased premises as she was about to begin her daily employment. Nevertheless, by construing the policy liberally in favor of the insured — a procedure necessitated by the ambiguity of the “arising out of” language — the instant injuries appear to have arisen from the operation and use of the leased premises, since they would not have been sustained “but for” the victim’s employment on those premises. She was about to commence her employer’s operation when she was assaulted. She, in fact, was holding keys to open the office. Her presence in the terminal at that hour was not a fortuitous happenstance, but a regular and foreseeable occurrence. The policy, therefore, reasonably must be construed to cover any risks attendant upon her presence there resulting from C&NW’s negligence and thereby activates Maryland’s duty to defend C&NW.
Finally, although generally considered an unambiguous word referring to a fixed situs, “premises” has also been held to include “private approaches and other areas necessary or incidental to an insured’s operations.” Allstate Insurance Co. v. Gutenkauf (1981),
The construction of an insurance policy is a matter of law. Summary judgment is an appropriate disposition where such construction is at issue, as here. (State Farm Mutual Automobile Insurance Co. v. Schmitt (1981),
II
Maryland next argues that the excess coverage Checkmate policy does not cover C&NW for its liability in the instant occurrence. That policy provides in part, under section 3.1, that Maryland “will indemnify the Insured [Demos] for ultimate net loss in excess of the retained limit which the Insured *** shall become legally obligated to pay as damages because of Personal Injury Liability ***.” The retained limit in the instant policy under section 1.4 is $10,000. Although the Checkmate policy does not designate an additional insured, section 4.2(d) in relevant part extends coverage to “any additional Insured included in the underlying insurance but only to the extent that insurance is provided to such additional Insured thereunder.” C&NW is such an additional insured in the CGL policy. Coverage under this provision, however, attaches only after the predetermined $10,000 retained limit has been exhausted. (Whitehead v. Fleet Towing Co. (1982),
III
Maryland lastly characterizes as premature the circuit court’s ruling that Maryland must ultimately indemnify C&NW.
1
An insurer’s duty to defend is broader than its duty to pay. (Murphy v. Urso (1981),
Accordingly, we affirm the finding as to Maryland’s duty to defend C&NW under its comprehensive general liability and excess coverage policies to the extent indicated in this opinion; and reverse and vacate as to Maryland’s present duty to indemnify C&NW.
Affirmed in part; reversed and vacated in part.
STAMOS and PERLIN, JJ., concur.
Notes
Although the order granting summary judgment refers to “potential indemnification,” the court’s oral riding refers to “ultimately indemnify” and “ultimately pay.” For purposes of certainty and clarity, the order will be treated here as imposing upon Maryland the “ultimate” duty to indemnify.
