COMPUTING THE AMOUNT FOR FIXED-INCOME INSTRUMENTS

 The amount displayed by the BMV-SENTRA Capitales system does not contemplate the calculation of interest.

 The amount of the trade plus interest accrued may be viewed by broker-dealers by querying the SIVA system, MCCLC (Settlement by Broker-Dealer Query) once the corresponding trading session has ended.

 The applicable formulas for determining the amounts are as follows:

Instruments in Pesos

Amount = Number of securities X Market Value

Instruments in Udis

Amount = N° of shares X Market Value X Value of the UDI

 The Original Face Value will be updated as advance redemptions occur.

 The Udi value to be considered for trade settlement will be the UDI on the day the trade takes place as posted.

Instruments in US Dollars

Amount = N° of shares X Market Value X Exchange Rate

 For Issuers indexed to the US Dollar, the exchange rate published in the Diario Oficial [Official Daily Gazette].

 For trading purposes, the following shall be observed:

 For same-day settlements, the previous day’s exchange rate will be used.

 For 24-hour and 48 hour settlements, the exchange rate on the day of the trade will be used.

The formula for determining accrued interest is as follows.

Interest Calculation

Interest = [(Average rate) X Days elapsed] X Updated Face Value X Volume 360

 For interest calculation, the days contemplated shall be from the date of the are reflected in the SIVA System by querying MCCTIN.
