If an investor owns one share of Berkshire Hathaway class A common stock and he sells 15 out of the money calls on Berkshire Hathaway class B common stock are the calls qualified? I refer the reader to the following URLs: https://ttlc.intuit.com/questions/2586341-a-question-about-berkshire-hathaway-and-the-wash-rule?jump... http://www.law.cornell.edu/cfr/text/26/1.1092(c)-1 Now, if he buys back those calls at a loss, is the loss deducible? Does the straddle loss limit rule apply? Note that one class A share is convertible to 1500 class B shares. However, you cannot convert 1500 shares of class B to one share of class A. Also note that one class A share has the same voting rights as 10,000 class B shares. Bob
