It's a safe assumption. The cost associated with the recent Reduction In Force (RIF) was realized in the fourth quarter. All imposed efficiencies had to be completed before the end of the year because the 1st quarter will be hugely important from the perspective of wall street. The financial results for Q4 will be offset by some of the restructuring costs so they have a built-in excuse for Q4, There will be no excuses in Q1. John V will get up in early February to lay out a new plan for Xerox and talk about all the great improvements that have been made. The anticipation of this announcement has bought him some time, but now everyone will be watching the 1Q19 results to see if the new plan is working. All that being said, there may be some layoffs here and there, but no more large layoffs should be expected (at least until April/May when Q1 results will dictate if additional restructuring is needed to boost profits).
I agree with what’s said in this post by @XaHGuzw-axt .
