Thank you for that question.
Yes, our assets have changed considerably. For the committee I'll mention that our assets are normally about $50 billion, about $20 billion in treasury bills, $30 billion in bonds. With the last operations we've done we've increased our lending through PRA to financial institutes by $35 billion. To make room for that we sold about $10 billion to $12 billion of our treasury bills. The government has sold treasury bills and put some deposits in the bank for the rest. Our total balance sheet has gone up from $50 billion to a little less than $80 billion.
The quality of our assets is still very high. In terms of the purchase and resale agreement, yes, we are purchasing less liquid assets than the government. So banks are pledging that to us. It's not a purchase per se, it's a term purchase and resale. So the institution that is pledging that asset to us has an obligation to come and buy it back from us. In a sense, we can look at this as kind of a loan, if you wish.
Secondly, the assets we accept are longer-term government securities, some commercial papers, bankers' acceptances, mortgage-backed securities. The assets that we accept are still very high-quality assets. And we are having our cut on that, so the lending is less than the value of the assets.
