Multiply pre-14 October working share prices by (9.27 - 2.20) / 9.27. This is an Index valuation/reinvestment convention, not an actual warrant trade or the unverified 14 October warrant close. The warrant is not a continuing Index constituent. The NYSE's diluted-share reference adjustment of $0.19368 is not the eligible public holder's full entitlement. The implied reinvestment reference is the theoretical ex-distribution common value USD 7.07."
