Aug. 2 (UPI) -- Berkshire Hathaway on Saturday reported a 3.79% decline in second-quarter earnings as CEO Warren Buffett's company warned about troubling times because of President Donald Trump's tariffs on imported goods.

Buffett, who has been involved with the company for 60 years, owns about 15.1% of its economic interest and 31.2% of its voting interest as its largest shareholder.

The public company reported an operating profit of $11.16 billion, with a lower number from a decline in its assets, which include insurance underwriting for Geico. The first-half decline was 8.8% at $20.8 billion.

Net income in the second quarter dropped to $12.37 billion, which is a 59% slump from the second quarter last year.
