Responding to risks from global market shifts and continued economic uncertainty, an increasing number of companies are undergoing major transformations to build new business models, tap into new channels and markets, and rethink supply chains and business locations, according to the latest risk-related survey from PwC.

The Big 4 firm’s “Risk in Review” study suggests more than two-third of companies have undergone a major transformation in the past 18 months, and another 10 percent plan to do so in the coming 18 to 24 months. Those results are based on a survey of 800 executives and risk managers throughout the world, 64 percent representing public companies.
