"Murphy noted three things that helped the Packers offset some of the revenue shortfall. The team didn’t need to dip into its corporate reserves, now up to $511 million, but it used those funds to open a credit facility (Murphy declined to comment on the specifics of that facility)."
They opened up a "Credit facility", which is similar to a line of credit (i.e. they have access to funds that they can borrow). Now, they may intend to use those funds to build a new practice facility, but these comments were about getting access to credit.
