So about a year ago, we actually segregated our portfolio into segments. And with that, we are now able to get a more granular view of just how we can actually allocate NES between the operating units that you mentioned, Agricultural Finance, and Rural Infrastructure Finance, and then Treasury as its split out between the actual funding desk and then our investment portfolio. So when we actually spread the interest rate benefits across the operating units, what we do is we assume that with all other things being equal, the way in which we would fund the balance sheet, if we did not have a Treasury desk, would be through match-funding every single loan, relative to the benchmark interest rate based on the tenor of that loan. In reality, what we do is we don't assume any interest rate risk. But we will actually hedge or synthetically convert a fixed or floating rate asset into an appropriate liability, and actually match the duration and convexity of the asset and liability. So this gets to be a little bit technical. But essentially, the way to think about this is, the funds transfer pricing mechanism that we use, provides a baseline of what funding costs would be out in the marketplace in the absence of the Treasury desk. So to the extent that the assets are being generated at a spread above this market rate, they get credit for it to the extent that the Treasury funding desk is able to issue debt the level of this market rate that we calculate, then that credit is ascribed to the Treasury unit. So essentially, what has happened over the past year, has been that we've been able to opportunistically fund at certain points in the yield curve, and issue debt that's been below the market rate. So that's one factor. The other factor is just as persistent benefit that we received when we extended our debt, as well as raised additional capital to preferred issuances that related to an excess in capital, that gets reinvested in the investment portfolio, that reduces the cost of borrowing. So those are the two big drivers. But the formal explanation really gets us I would say, in all environments, how we really ascribe that NES and apportion it across our lines of business, that's Agricultural Finance and Rural Infrastructure Finance, and then the Treasury.
