The current limit is $25 million. The CBC has not actually borrowed to this date; the increase will allow them to borrow a larger amount, up to $220 million. The proposed structure of the borrowing is by way of monetizing certain receivables, so it'll be a market borrowing. It won't be at the government's rate; it'll likely be higher than the government's rate.
