So as lending agent, I'm also checking the collateral that's been posted every single day against the loan of the securities mark-to-market to make sure the collateral is worth in excess of the securities that are, that have actually been lent out. I'm doing this to protect my client. Everyday I'm making sure that daily margin calls are made at the agreed haircut percentage as this is the income that has been agreed to be obtained on behalf of my client. Now no security loans are released until the collateral and the initial margin has been received from the borrower. It's not a case of we will give you the securities, then you give me the collateral. It's completely, if you want these securities, you will post the collateral and pay the margin call before you get the securities. Now as the lending agent, I will also be checking that the collateral is of suitable eligibility. I.e. it's liquid, it's not something that I cannot sell to actually obtain cash if I absolutely need to. So all collateral has to be liquid. It's all within certain concentration limits to make sure that we're not getting too much of the same collateral. We want to be able to spread that because if we need to liquidize the collateral, we don't want the to be a drop in that collateral's price because we had such a large chunk of it that's being sold. We also check and keep a monitor of the limits that each borrower has got and we're also checking on the NAV limits of the fund. You wouldn't want too much of the fund's stock to actually be lent out. And this is all controlled through the back office of the custodian's stock lending system.
