Berkshire Hathaway’s new CEO Greg Abel has invested $10 billion in Google’s parent company and repurchased about $4.5 billion of its shares. The conglomerate that legendary investor Warren Buffett built reported its second-quarter earnings Saturday morning and disclosed that its cash holdings had shrunk more than $30 billion to $365.5 billion. Abel announced in March that Berkshire had resumed buying back its own shares for the first time in more than two years, but investors were underwhelmed with the buybacks in the first quarter.
