The rst choice above, on the otherhand, allows for their attribution to each period by isolating the losses. This will be clearer in what follows. Although not specied up to now, it is important to stress that we are valuing all contracts under a risk-neutralmeasure, and all expectations should be considered as computed with respect to this measure. In practice, each party knows that it may beforced to yield something with respect to the value of the contract. Following this route we totally bypass choosing the discount rate. The axiom assumes that the evaluators of the banks investments are the shareholders.
In other words, assetscannot be xed rate bonds and spreads have to be reviewed not only to reect theobligors default risk but also that of the bank.

The comment change in the position of borrowers necessarilyalters the position of shareholders39 is true, but the balance sheet should report just thelatter position and not mix both together. The main result of this section is that the choice of discounting rate for positive and negative cash ows poses no problems even when there is a default risk premium andfunding costs, when these are taken into account in a consistent manner. The links between credit risk and funding cost 423. This condition is tantamount, fromthe banks perspective, to assuming the possibility to buy an asset that is default risk freeand yet yields more than the risk-free rate.
This quantity can be replicated without any theoreticaland practical hindering, since it is possible to trade short bonds issued by the otherparty. In fact, it is true that the bank will repay onlya fraction or nothing of its debt on default, but this is a false saving of money, since notfully paying back debt obligation simply means that no equity is left to cover losses. Every financial firm is tasked with finding its own solutions based on its specific features. Apparently, L has to discount the positive cash ows received at T at a discount rate that includes the risk-free rate, its own funding spread and the borrowers fundingspread. To the debtor, the value of the liability is just the present value discounted at the risk-free rate of the notional amount thus strictly adhering to thegoing concern principle. This is the loss that the counterpartymay expect to suer, given the default of the bank.
The book then goes on to look at tools which can be used to measure liquidity risk, discussing risk monitoring and the different models used, notably financial variables models, credit variables models, and behavioural variables models, and then at managing these risks. Because shareholders usually cannot be called on to pay a corporationsliabilities, the amount of their residual claims approaches, and is limited by, zero.

The same is true for the counterparty.
The book then goes on to look at tools which can be used to measure liquidity risk. This compensation is the present value of the extra costs given Axiom 10.

To deliver the underlying to the repo counterparty, the bank buys the asset onthe spot market using the cash it receives from the repo sell leg. The book then goes on to look at tools which can be used to measure liquidity risk, discussing risk monitoring and the different models used, notably financial variables models, credit variables models, and behavioural variables models, and then at managing these risks.
