They are NOT comparable with the acquisition-cost or book-value-reduction figures quoted in press coverage and IR presentations, and NOT comparable with interim (half-year) figures, which this product does not hold. Always state the basis with the number, and use check_claim before setting one of our figures against a published one."}}
