Stager to Loblaw set the reserve at $31,500. By May, 1969, a medical report indicated that Uzarowski would never return to work. In December, 1970 Stager reported to Loblaw that $15,089.79 in compensation and $5,971.25 in medicals had been paid and that Loblaw “might wish to contact the excess carrier”. Although Trial Term found that notice was given on April 10, 1970, Loblaw concedes that Employers was not notified until June, 1972. Employers responded on July 18, 1972 that it reserved its rights under the policy and would investigate the claim. Subsequently, Employers disclaimed coverage on grounds that the notice was not timely. The issue presented is whether Loblaw complied with the following notice provision of the policy: “Notices to Company. D. The Self Insurer, upon the occurrence of any accident
which in the opinion of the Self Insurer may involve liability on the part of the Company shall give immediate written notice thereof, with the fullest information obtainable at the time, to the Home Office of the Company at Boston, Massachusetts. The Self Insurer shall give like notice with full particulars on any claim made or suit brought on account of such accident. When required by the Company, the Self Insurer shall forward to it copies of every summons or other process that may be served upon the Self Insurer in connection with any accident which, in the opinion of the Company, may involve liability on the part of the Company.” (Emphasis added.) Loblaw urges that the provision be construed so as to require notice only when an accident occurs or a claim is filed which, in its opinion, will involve excess coverage. Alternatively, it argues that notice is required only after the $25,000 retention has been paid. Employers; on the other hand, urges that written notice was required at such time as it appeared to Loblaw, in the exercise of good faith, that a claim arising out of an accident occurring during the policy period was likely to exceed the retention. Loblaw argues that there is a patent ambiguity which- must be construed against the insurer and in favor of the insured (see
Breed v Insurance Co. of North Amer., 46 NY2d 351 ;
Sturges Mfg. Co. v Utica Mut. Ins. Co., 37 NY2d 69 ;
Hollander v Nationwide Mut. Ins. Co., 60 AD2d 380 , mot for lv to app den 44 NY2d 646 ). That rule, however, is not applicable in a contest between two insurance companies
(Standard Mar. Ins. Co. v Federal Ins. Co., 39 AD2d 444 , 446). While it is true that Loblaw is not an insurance company, where, as here, it acts as a self-insurer with respect to workers’ compensation claims through its agent, a licensed insurance adjusting company, its status is more akin to that of an insurance company than to that of an individual who is inexperienced in matters of insurance coverage for whose benefit the rule was promulgated. Moreover, ambiguities will not be resolved in favor of the insured where the only reasonable construction which can be placed upon the words favors the insurer
(Hollander v Nationwide Mut. Ins. Co., 60 AD2d 380 , 384,
supra). Additionally, in interpreting such provision, the contract must be read as a whole to determine what the parties must have reasonably intended by its terms
(McGrail v Equitable Life Assur. Soc. of United States, 292 NY 419 ;
Little v Blue Cross of Western N. Y., 72 AD2d 200 ). Mindful of the foregoing principles, we turn to examination of the policy. The purpose of the policy is to protect Loblaw against the risk of claims under the Workers’ Compensation Law, exceeding $25,000. Employers requires notice of such claim in order to facilitate the setting of reserves, to predict liabilities, and to protect itself by investigating such claims (see
Security Mut. Ins. Co. ofN. Y. v Acker-Fitzsimons Corp., 31 NY2d 436 , 440). Additionally, such notice invokes another paragraph of the policy, under which Employers is given the right to participate in settlement or defense of any claims. WThen viewed in the context of the purpose and intent of the policy, the phrase “which in the opinion of the Self Insurer” must be construed by an objective standard to mean when Loblaw knew or reasonably should have known that it was likely that excess coverage
