The heading for the column starting with £15824.56 is "Present(GBP)"
... for the column starting €14805.44 is "Total"
I agree that the bottom three amounts in the first column adds up to
£15824.56
Also
The total value of the three stock in Euro terms (see below) is €14805.44
The price of the shares and the Euro/Pound exchange rate were obtained
at (about) 1000 GMT this morning (ie approximately 11 hours ago). I
"froze" the book at that time so that I could work with fixed values.
The full details for each share follows:
Airbus
114 shares @ €85.56 equals €9753.84 @ (€0.89662 = £1) thus value
=£8745.49 *NOT £11631.65*
Deutsche Post
80 shares @ €38.92 equals €3113.60 @ (€0.89662 = £1) thus value
=£2791.72 *NOT £2361.44*
**
SAP
19 shares @ €102.00 equals €1938.00 @ (€0.89662 = £1) thus value
=£1737.65 *NOT £1831.77*
For completeness:
The implied Euro/Pound exchange rates for
Airbus (the conversion of €9753.84 to £11631.65) 1.1925
Deutsche Post (the conversion of €3113.60 to £2791.72) 0.7584
SAP (the conversion of €1938.00 to £1831.77) 0.9452
Take care
