Aimene Farid, Bahi Nawel:Operational Risk Estimation Using the Value-at-Risk (VAR)
                                  Method: Case Study of the External Bank of Algeria (EBA)


                    Formation of Operational Risks Based on The Distribution of Losses
                    We mentioned earlier that not all risk factors need to be quantitatively modeled, but only
                    those that belong to expected and unexpected losses. These factors must be divided into
                    four  partial  spaces  according  to  the  area  map  of  operational  risks  (see  Figure  03).
                    Therefore, in order to form the operational risks that must be quantitatively modeled, we
                    first need to challenge the frequency and value of loss for each risk factor:

                    Determining The Frequency And  Value  of Loss For The Event of Computer Failure
                    The following table shows the frequency and loss value of the computer failure event
                    for the period 2012-2020:

                    Through the previous table, we note that the total frequency of disruption of the bank's
                    computers has reached 27 events distributed over 9 years from 2012 to 2020, while
                    the total value of losses per event reached 180 thousand DZD during the same period.
