Abstract: | This article recasts the optimal allocations of coverage limits for two independent random losses. Under some regularity conditions on the two concerned probability density functions, we build the sufficient and necessary condition for the existence of the optimal allocation of coverage limits, and derive the optimal allocation whenever they do exist. The results supplement Lu and Meng (2011 Lu, Z.Y., Meng, L.L. (2011). Stochastic comparisons for allocations of upper limits and deductibles with applications. Insur.: Math. Econ. 48:338–343.Crossref], Web of Science ®] , Google Scholar], Proposition 5.2) and Hu and Wang (2014 Hu, S., Wang, R. (2014).
