Post-sale reporting

[ESMA 35-43-349 MiFID II Q&As on Investor protection Ch. 8, question 7] Firms should continue to refer to the value of the portfolio at the beginning of the reporting period to calculate the multiples of 10%.  For example, if a portfolio is valued at 100,000 at the beginning of the period, it first reports if the portfolio falls to 90,000. A second reporting requirement would occur at 80,000 and a third at 70,000 (i.e. multiples of 10% of the value at the beginning of the reporting period). If the value of the portfolio is 70 000 at the beginning of the next reporting period, a first report for that reporting period would occur at  63 000.
