MEMORANDUM DECISION AND ORDER I. INTRODUCTION This is a declaratory judgment action between the insurance companies of a general contractor and its subcontractor after an accident at a construction site. The general contractor — Eilerson Development Corporation (“EDC”) — and its insurers — Amerisure Insurance Company and Amerisure Mutual Insurance Company (collectively, “Amerisure”) — brought third-party complaints against Selective Insurance Group, Inc., which insured the job’s subcontractor. See Dkt. Nos. 14 (“Amerisure Complaint”); 15 (“EDC Complaint”).1 Now before the Court are motions for summary judgment filed by Selective and Amerisure. See Dkt. Nos. 43; (“Selective’s Motion”); 43-14 (“Selective’s Statement of Material Facts” or “Selective’s SMF”); 43-15 (“Selective’s Memorandum of Law”); 44 (“Amerisure’s Motion”); 44-16 (“Amerisure’s Statement of Material Facts” or “Amerisure’s SMF”); 44-17 (“Amerisure’s Memorandum of Law”). Selective and Amerisure oppose one another’s motions. See Dkt. Nos. 51 (“Selective’s Opposition”); 52-1 (“Amerisure’s Opposition”)2. Each filed a reply. See Dkt. Nos. 56 (“Amerisure’s Reply”); 57 (“Selective’s Reply”). For the reasons discussed below, the Court grants in part and denies in part Selective’s Motion and denies Amerisure’s Motion in its entirety.
