This is from the 21 November acquisition announcement and seems pretty clear, particularly as the timeframe has been adhered to pretty well and all resolutions passed:

1. The Transaction is expected to complete in the first quarter of 2018. Under the terms of the Transaction, the effective economic date for the transfer of ownership of Peak to Aurelia will be 1 January 2018 even where the Transaction completes after that date. Further details of the Transaction arrangements can be found in Appendix A of this announcement.
