Wikipedia says they have 12,736 employees.
$1B works out to $78,518 per employee (before payroll taxes, health insurance, etc.).
So if you're trying not to lay people off and keep the company afloat while revenue has plummeted to next-to-nothing... it's not an absurd figure. Or even if you're laying people off, it's going to take $$$ to find and rehire and train people when revenue starts coming in again, while continuing to pay the management team and key employees that will be capable of executing on that, and keeping the lights on, and paying rent.
Granted almost 13K employees may sound like a lot... but let's say they operate in 50 countries and have a team of 100 people for each one building up the business, that's 5,000 employees already. I made those specific numbers up, but for a global-local company, it's not crazy.
