Notes to the <strong>Financial</strong> <strong>Statements</strong> <strong>of</strong> UniCredit <strong>Bank</strong> <strong>Austria</strong> AG<br />

In the second quarter <strong>of</strong> <strong>2011</strong>, UniCredit <strong>Bank</strong> <strong>Austria</strong><br />

AG was granted permission by the <strong>Austria</strong>n<br />

supervisory authority to replace the risk model<br />

("NoRISK") developed by the bank itself, which has<br />

been used for many years, with the new IMOD model<br />

used within the entire UniCredit Group. This switch<br />

constituted a significant change <strong>of</strong> model in<br />

accordance with Section 21e <strong>of</strong> the <strong>Austria</strong>n <strong>Bank</strong>ing<br />

Act. The new model is based on historical simulation<br />

with a 500-day market data time window for scenario<br />

generation. It is currently used on a uniform basis by<br />

many UniCredit Group subsidiaries. The model is<br />

applied by Market Risk within UniCredit <strong>Bank</strong> <strong>Austria</strong><br />

AG and is being further developed in cooperation with<br />

the UniCredit holding company. The conditions<br />

imposed by the college <strong>of</strong> supervisors (Italy, Germany,<br />

<strong>Austria</strong>) in the course <strong>of</strong> the approval process for the<br />

new model were largely fulfilled in <strong>2011</strong>. Moreover, in<br />

<strong>2011</strong> an application was filed with the regulators (BoI<br />

and FMA) for permission to use the models developed<br />

in UniCredit Group to comply with the new CRD 3 rules<br />

for the trading book which have been applicable since<br />

December <strong>2011</strong>. This applies in particular to the<br />

stressed VaR and IRC (incremental risk charge), while<br />

CRM (comprehensive risk measure) is not applicable<br />

to UniCredit <strong>Bank</strong> <strong>Austria</strong> AG for lack <strong>of</strong> credit-tranche<br />

holdings in the trading book. The relevant reviews in<br />

<strong>Bank</strong> <strong>Austria</strong> were completed by the <strong>Austria</strong>n<br />

supervisory authority with a positive outcome in <strong>2011</strong>.<br />

Approval for use <strong>of</strong> the new models was given as at<br />

year-end <strong>2011</strong>.<br />

As at 30 December <strong>2011</strong>, VaR at UniCredit <strong>Bank</strong><br />

<strong>Austria</strong> AG for the respective risk categories was as<br />

follows (calculated on the basis <strong>of</strong> the new model):<br />

(in EUR)<br />

Exchange rate risk, overall -1,321,717.24<br />

Equity position risk, trading book 0.00<br />

Equity position risk, banking book -11,408,788.71<br />

Interest rate position risk, trading and banking books -6,372,392.61<br />

Credit spread risk (VaR limit scope) -32,968,618.29<br />

Overall market risk (VaR limit scope) -43,300,668.00<br />

Overall market risk arising from the above components -55,831,924.84<br />

The above figures are based on the new internal<br />

Group-wide model.<br />

For the purpose <strong>of</strong> determining capital requirements,<br />

the new model has been used since April <strong>2011</strong>. The<br />

parameters used in this context are a 10-day holding<br />

period, a confidence level <strong>of</strong> 99% and a multiplier <strong>of</strong><br />

3.5. As at 30 December <strong>2011</strong>, the capital requirement<br />

was EUR 43.9 m.<br />

The following capital requirements result for UniCredit<br />

<strong>Bank</strong> <strong>Austria</strong> AG in connection with S-VaR and IRC:<br />

EUR 67.0 m for S-VaR and EUR 21.4 m for IRC.<br />

Within the <strong>Bank</strong> <strong>Austria</strong> Group, the reliability and<br />

accuracy <strong>of</strong> the internal model is monitored by daily<br />

backtesting, comparing the VaR amounts with the<br />

actually observed fluctuations in market parameters<br />

and in the total value <strong>of</strong> the trading books. In <strong>2011</strong>,<br />

there was no negative backtesting excess. The results<br />

<strong>of</strong> backtesting have thus confirmed the accuracy and<br />

reliability <strong>of</strong> the model. The multiplier <strong>of</strong> <strong>of</strong> 3.5 therefore<br />

remains unchanged.<br />

Value-at-risk calculations are complemented by<br />

various stress scenarios to identify the potential effects<br />

<strong>of</strong> stressful market conditions on the Group’s earnings.<br />

The assumptions made under such stress scenarios<br />

include extreme market movements and a dramatic<br />

deterioration in market liquidity.<br />

Market risks resulting from the general balance sheet<br />

structure and the positioning <strong>of</strong> asset-liability<br />

management are additionally determined and regularly<br />

analysed by means <strong>of</strong> simulations <strong>of</strong> net interest<br />

income volatility. In addition to the business volume at<br />

the reporting date, these simulations are based on<br />

various interest rate scenarios, assumptions regarding<br />

new business, demand behaviour and general<br />

developments affecting margins in those market<br />

segments which are <strong>of</strong> greatest importance to<br />

UniCredit <strong>Bank</strong> <strong>Austria</strong> AG. Modelling over the<br />

projection period provides indications <strong>of</strong> trends in net<br />

interest income and enables the bank to identify risks<br />

at an early stage and to take appropriate measures.<br />

In addition to calculating VaR for trading activities, the<br />

bank uses the Value-at-Risk method for measuring<br />

market risk in the banking book.<br />
