Longtime Berkshire board member Ron Olson told Yahoo Finance he thinks the new roles for Abel and Jain will take some pressure off of Buffett and make it easier for him to continue running Berkshire, which includes an eclectic mix of more than 90 companies.
It came two days after Buffett revealed having bought 75 million additional Apple shares, and four days after Apple said it may buy back $100 billion of stock.
Apple now accounts for a quarter of Berkshire Hathaway's assets and is the biggest holding for it.
Berkshire Hathaway chairman Warren Buffett answered questions on a wide range of topics at the company's annual shareholder meeting in Omaha on Saturday, including U.S.

There are likely to be questions about who will eventually replace Buffett, where the company will invest more than $116 billion cash and maybe questions about career advice.

Berkshire typically discloses its largest common stock holdings and percentage stakes in its quarterly and annual reports. "I don't agree with that", said Catherine Keane, a 67-year-old shareholder attending her first annual meeting.
Besides investments, Berkshire owns more than 90 subsidiaries in a variety of industries, including insurance, utilities, railroads, and manufacturing.

The accounting change required Berkshire to report unrealized losses in its equity portfolio, which totalled $170.5 billion at year end, regardless of whether it planned to sell those stocks.
Berkshire said its operating profit, which Buffett considers a better performance measure, rose 49 percent to $5.29 billion, or about $3,215 per Class A share, from $3.56 billion, or $2,163 per share, a year earlier. The shares closed up 3.9% at $183.83 on Friday.
