The number of futures contracts to sell are equal to $10m x 1.1/$50,000 = 220. Liquidating his portfolio would reduce the beta to zero, but would also get rid of the bets he wants to play on. Therefore Choice 'c' is the correct answer.
(Note that futures and spot prices generally move together allowing futures positions to be used for hedging the risk against movement in spot prices. However there is a basis risk between spot and futures, therefore the a perfect hedge is never possible with futures. If interest rates move a great deal, spot and futures prices may diverge. Of course, this risk is generally quite low but may become amplified with large leveraged portfolios.
Just something to be aware of.)

The CDS rate is approximated by the [Loss given default x Default hazard rate]. Thus Choice 'b' is the correct answer.
Note that this is also equal to the credit spread on the reference bond over the risk free rate. Therefore credit spreads and CDS rates are generally the same. Also, 'loss given default' is nothing but (1 - Recovery rate).
This can be substituted in the formula for the credit spread to get an alternative expression that directly refers to the recovery rate. Therefore all other choices are incorrect.

In December 2009 the BIS came out with a new consultative document on liquidity risk. Given the events of
2007 - 2009, it has been clear that a key characteristic of the financial crisis was the inaccurate and ineffective management of liquidity risk The paper two separate but complementary objectives in respect of liquidity risk management: The first objective relates to the short-term liquidity risk profile of institution, and the second objective is to promote resiliency over longer-term time horizons. The paper identifies the following two ratios - you should be aware of these - though I am not sure if these will show up in the PRMIA exam:
1. Liquidity Coverage Ratio addresses the ability of an institution to survive an acute liquidity risk stress scenario lasting one month. It is calculated as follows:
Liquidity Coverage Ratio = Stock of high quality liquid assets/Net cash outflows over a 30-day time period
2. Net Stable Funding Ratio has been developed to capture structural issues related to funding choices.
Net Stable Funding Ratio = Available amount of stable funding/Required amount of stable funding Both ratios should be equal to or greater than 1. The statement contains detailed definitions of what is included or excluded from each of the terms used in the calculations for each of the ratios. In addition, the standard also describes the what the 'acute' scenario should include (things such as a 3 notch credit downgrade, reduction in retail deposits etc) Therefore Choice 'b' is the correct answer. Book Value to Share Price and Earnings Per Share are accounting measures unrelated to liquidity.

Strong management of collateral, both receivable and payable, is emerging as an area requiring significant investment by financial institutions and asset managers in IT infrastructures and business processes. A bank needs to make collateral calls daily, based upon the P&L of the previous day, and likewise receives collateral calls from its counterparties. Just like cash, a bank needs to make sure that it does not run out of collateral to post when a call is received. Interestingly, based upon the agreements between banks and their mutual understanding, only certain types of instruments often qualify as valid collateral - and in such cases even cash is not acceptable if the right type of bond or other agreed security is not available to post. The operational challenges of managing collateral increase manifold due to 'rehypothecation', ie when collateral received from one counterparty gets posted out as collateral where it is due. In such cases, the bank should have the mechanisms to receive the right assets back in a timely way in case rehypothecated assets are to be returned.
The systems should be able to deal with delays, failures without impacting the ability of the bank to post collateral as needed. All of this requires major investments in IT and processes.
Statement I is not true as a bank is bound to post collateral to third parties when needed regardless of the failure of its counterparties to post collateral to it when owed. In the markets, failures by counterparties can and do happen, and a collateral management system needs to account for and keep a buffer for the fact that some collateral when due will not be received.
Statement II is not true as rehypothecation by counterparties of collateral posted increases the chances of the collateral not being received in time. The system should consider the need for liquidity to generate assets that can be posted as collateral when others have failed to return the collateral in a timely way.
Statement III is not correct as cash may not be acceptable to counterparties as collateral. From a practical point of view, they may not have the infrastructure to receive and account for cash as collateral. A Swiss bank, for example, may have an 'account' to receive US t-bills as collateral but may not even have a US dollar account to receive cash. Even if it did, the volumes of transactions going back and forth may make tracking and reconciliations impossible. Thus a bank should always make sure that it has the right type of collateral available to post.
Statement IV is incorrect as well, as treasury issued instruments are also subject to haircuts. Their value also fluctuates in response to changes in yields, and therefore they are subject to haircuts as well.
Thus none of the statements are correct and Choice 'd' is the correct answer.

Using the beta for VaR calculations is a significant simplification based on the CAPM and the assumption that any specific risks are diversified away. The one thing a risk model based on the CAPM does not consider is the specific risk of individual stocks, because, as mentioned, these are considered to be offsetting each other so that the portfolio only carries market risk reflected in the beta.
Therefore Choice 'c' is not true and therefore the correct answer.
