On November 26, 2020, the Office of the Superintendent of Financial Institutions (" OSFI") issued for public comment a draft revised Guideline B-2, Property and Casualty Large Insurance Exposures and Investment Concentration (the " Draft Guideline") which would replace the current Guideline B-2, Investment Concentration Limit for Property and Casualty Insurance Companies (the " Current Guideline"). The significant changes to the Draft Guideline address single large insurance exposures of federally regulated property and casualty insurers (" P&C Insurers"). The Draft Guideline departs from a proposal in 2018 (the " 2018 Proposal") that, among other things, required that P&C Insurers be able to cover their three largest policy limit losses.
