From US Chamber of Commerce:
The Federal Reserve in a press release on April 30, 2020 announced significant and positive changes to The Main Street Lending Program. The Fed lowered the minimum loan size to $500,000 from $1 million, and expanded the pool of eligible borrowers to businesses with 15,000 employees (up from 10,000) or up to $5 billion in revenue (up from $2.5 billion) among other changes made of which CCMC advocated for in their letter sent to the Fed on April 16th. These improvements will make the program accessible to more American businesses, and will help eligible lenders administer the program more effectively.
