Toronto's SkyDome was owned and operated by Sportsco. The Toronto Blue Jays rented the building for their home games. One of those games, against the Kansas City Royals, was cancelled after portions of SkyDome's retractable roof broke off and fell to the ground. The Blue Jays sued Sportsco in tort for its loss of profits. Sportsco was worried that the lawsuit might become very expensive, not only because of the need to hire lawyers, but also because of the need to hire expert witnesses to explain why the roof fell apart. Sportsco did, however, have an insurance policy that it had purchased from ING Insurance Company of Canada. Explain the significance of that policy.
