OMAHA, Neb. (AP) — Warren Buffett's company reported Saturday that it saw an 11% decline in third-quarter profits because of a smaller increase in the paper value of its investments, even as it sits on a mountain of cash.

Berkshire Hathaway said it made $16.52 billion, or $10,119 per Class A share, in the quarter, down from $18.54 billion, or $11,280 per Class A share, a year ago.

Buffett has long said Berkshire's operating earnings offer a better view of quarterly performance because they exclude investments and derivatives, which can vary. By that measure, Berkshire's operating earnings improved to $7.86 billion, or $4,812 per Class A share, from $6.88 billion, or $4,186.05 per Class A share.

Analysts surveyed by FactSet expected operating earnings per share of $4,299.20 on average.

Berkshire Hathaway recorded an $8.67 billion paper investment gain during the quarter. A year ago, it registered an unrealized $11.66 billion investment gain.

Berkshire's revenue improved 2% to $64.97 billion.

Edward Jones analyst Jim Shanahan said the results look good overall despite the ongoing challenges of the U.S. trade war with China and weakness in manufacturing, but it's disappointing that Berkshire didn't find a way to use more of its cash.

Berkshire is sitting on a pile of more than $128 billion cash because Buffett has struggled to find major acquisitions for the company recently. Buffett said Berkshire repurchased about $700 million of its shares during the quarter.

"Whenever this market pulls back meaningfully, they'll have a lot of capacity to put cash to work," Shanahan said.

Berkshire said its BNSF railroad added $1.466 billion net income during the quarter, up from $1.393 billion a year ago, as it reduced costs as volume slowed.

Berkshire's utilities generated $1.18 billion net income, up from $1.09 billion a year ago.

The company's insurance units, which include Geico, generated $1.48 billion in investment income, up from $1.24 billion a year ago.

Berkshire Hathaway Inc. owns more than 90 companies, including BNSF railroad and clothing, furniture and jewelry businesses. Its insurance and utility businesses typically account for more than half of the company's operating income. The company also has major investments in such companies as Apple, American Express, Coca-Cola and Wells Fargo & Co.
