Investor Warren Buffett says he plans to decide whether to scale back his company’s annual meeting, which typically attracts roughly 40,000 people, around April 1.

Berkshire Hathaway is still planning to hold its annual meeting on May 2, but the ongoing coronavirus outbreak may force the company to make changes to the event.

Buffett told Yahoo Finance that he will follow the advice of public health officials when deciding whether to alter plans for Berkshire’s annual meeting. The event includes a massive trade show where Berkshire companies, such as Fruit of the Loom, Geico and Pampered Chef, sell products.

“It definitely may be scaled down,” Buffett said during an interview with Yahoo Finance. “We’ll consider that between now and roughly the first of April. Then we’ll announce, so people can make their plans.”

The meeting usually attracts a huge crowd of people who want to hear Buffett and Berkshire Vice Chairman Charlie Munger answer questions over several hours.

The meeting itself will be broadcast online by Yahoo Finance, so investors don’t have to travel to hear Buffett’s and Munger’s answers.
