Article 49U.K.Conversion and interest
1.Where the calculation of compensation requires the conversion of sums expressed in foreign currency, conversion shall be at the exchange rate applicable on the day and at the place of payment of the compensation.
2.The person entitled may claim interest on compensation, calculated at five per cent per annum, from the day of the claim provided for in Article 55 or, if no such claim has been made, from the day on which legal proceedings were instituted.
3.However, in the case of compensation payable pursuant to Articles 27 and 28, interest shall accrue only from the day on which the events relevant to the assessment of the amount of compensation occurred, if that day is later than that of the claim or the day when legal proceedings were instituted.
4.In the case of luggage, interest shall only be payable if the compensation exceeds 16 units of account per luggage registration voucher.
5.In the case of luggage, if the person entitled does not submit to the carrier, within a reasonable time allotted to him, the supporting documents required for the amount of the claim to be finally settled, no interest shall accrue between the expiry of the time allotted and the actual submission of such documents.
