LCR - Treatment of securities borrowing-transactions for non-refinancing-purposes

How should securities borrowed which were not borrowed for refinancing-purposes be recognised in the LCR?

An institution provides a securities lending-service to our customers to increase their return on portfolio. 1) In a first step our institution borrows assets (shares, bonds) from the customer. It is important to mention that the assets received from the customer neither increase the liquidity buffer nor are they used to cover short positions. Additionally a cash-collateral is provided towards the customer. This cash-collateral is booked on off-balance-accounts so there is no reduction of liquid central bank assets and furthermore no cash is leaving the institution. Regarding the claims on the Central Bank the institution is not subject to any restrictions preventing them to transfer their liquid Central Bank assets. Having a look on the contractual relationship with the customer the institution has the contractual right to give back the assets borrowed to the customer at any time and herewith the right to receive back the cash-collateral provided simultaneously. 2) In a second step the institution lends the assets received to a third party. The lending-fee received from the third-party is rewarded towards the customer. The mentioned borrowing-transaction is not driven by the purpose of refinancing our institution as the BCBS-standard 238 suggests, but to provide an additional service to our customers. The mentioned fees are transferred on a monthly basis. The third party first pays a borrowing fee to our institution. After this transaction, 50 percent of the received fees are rewarded towards the customer.
