The logic is simple :
To order this AOT into a whole set of AOTs, at a lower large order price, they had to cancel this individual lease, which imposes a price of 4,3 MUSD.
Note also that the October 15th date is the normal end of lease date had the installation been completed on april 15th as initially scheduled.
They HAD to cancel this lease on july 15th if they wanted to get a new wholesale price for this AOT, which, combined with the positive wording ("successfully complete testing") is a good indication about their future intentions.
