1991 Fairfax Holdings Letter to Shareholders

- Excellent set of letters from Prem Watsa at Fairfax Holdings. I am on a mission to finish all of his shareholder letters to learn more about how he replicated Buffett's approach at Berkshire Hathaway - i.e. using insurance float as a (near) cost-less means to boost return on shareholder equity as well as acquire more operating companies. Would highly recommend these letters!
