Berkshire Hathaway on Saturday reported a higher first-quarter operating profit even as economic uncertainty weighed on several of its consumer-oriented businesses. The Omaha, Nebraska-based conglomerate built by Warren Buffett and now led by Greg Abel also reported a record cash level, reflecting difficulty finding investments that meet its value-oriented principles. Profit from Berkshire's dozens of businesses rose 18% to $11.35 billion, or about $7,891 per Class A share, from $9.64 billion a year earlier. Net income, including from common stock investments, more than doubled to $10.1 billion, or $7,027 per Class A share, from $4.6 billion.
