Berkshire also added 2 million General Motors GM, -2.90% shares to give it 62 million shares of the automaker during a quarter when its cash pile shrank to $106 billion from $147 billion because of all of its stock purchases.

The filing Berkshire submitted Monday doesn’t make clear which moves Buffett made and which investments were made by Berkshire’s two other investment managers.
