Operational losses can be caused by external factors, deliberate,
accidental or natural, or failures of internal processes,
people or systems. They can unfortunately never be entirely
eliminated. Especially in todays environment of complex
global processes, low regulatory tolerance for error, and growing
propensity for litigation, operational risk runs alongside
market and credit risk as one of UBSs principal risk classes.
Our operational risk framework, into which we are investing
considerable management time and effort, aims to contain
the levels of risk, and ensures we have sufficient information
to make informed decisions about additional or adjusted
controls.
As far as accounting for operational risks is concerned,
many potential causes of loss are identified before the probability,
timing, or amounts of future cost are known with
certainty. This requires the exercise of judgment and International
Financial Reporting Standards (IFRS) require us to make
a provision, based on the best estimate of a liability, when it is
probable that a payment will be required, even if the amount
to be paid has not yet been exactly determined. Once we are
able to quantify any potential operational risk more accurately,
the corresponding provision is revised up or down.
