I think that’s the document that’s most important, in particular these sections:
Settlement of cash consideration
Each Scheme Shareholder on the register of members of Codemasters at the Scheme Record Time, being 6.00 p.m. on 17 February 2021, will receive 604 pence in cash for each Scheme Share held. Settlement of the consideration to which each Scheme Shareholder is entitled will be made in accordance with the terms of the Scheme, full details of which are set out in the Scheme Document. The latest date for the despatch of cheques or the crediting of CREST accounts (for Scheme Shareholders holding Scheme Shares in certificated form and in uncertificated form, respectively) in respect of the cash consideration in relation to the Acquisition is 4 March 2021 (being 14 days after today’s date).
Cancellation of admission of Codemasters Shares to trading on AIM
Trading in Codemasters Shares on AIM was suspended with effect from 7.30 a.m. today and admission of the Codemasters Shares to trading on AIM is expected to be cancelled with effect from 7.00 a.m. on 19 February 2021.
As a result of the Scheme having become Effective, share certificates in respect of Codemasters Shares have ceased to be valid documents of title and entitlements to Codemasters Shares held in uncertificated form in CREST are being cancelled.
So no to your answer about converting Codemasters to EA shares, but you could purchase EA shares.
If I am reading it right, then the latest Interactive Broker will receive the cash you are due, is Thursday the 4th of March. I’m not sure the turnaround times for IB to transfer the cash to 212, and 212 to reconcile and split the monies between all investors. Friday the 5th March, or potentially Monday 8th if I were to guess. I don’t know how automated the process is.
