For example, we now have nearly 200 bots working across the organization in areas such as order to cash, delivery, human resources and finance. Then in November, we restructured our relationship with Fujifilm and Fuji Xerox to both monetize an otherwise illiquid asset at an attractive valuation and establish a more traditional supply relationship, which will ensure we have the ability to source from the partner that can offer the highest value proposition. A combined company would be both more profitable and better positioned to diversify into higher-growth markets. For adjusted EPS, we are guiding to a range of $3.60 to $3.70 and $2.80 to $2.90 for GAAP EPS.On a full-year year-over-year basis, adjusted operating margin expanded 180 basis points. As we start 2020, Xerox is positioned to make further progress against our three-year plan. Ann?On IoT, we are expanding the testing of our sensing and analytics technologies with prominent partners across the world, from New York to Australia. Revenue and expense synergies are fully analyzed, but deal models only include expense synergies in the evaluation of our returns. Our second-half progress reversed the first-half top-line trajectory, but we have more work to do, and this continues to be an area of intense focus for us. The increase in full-year operating cash flow reflects higher profit, including the OEM fee; better net working capital of approximately $25 million, driven by improvements in inventory management; and approximately $30 million of cash from finance assets.And a lot of that continuing to come from Project Own It initiatives, which we're targeting $450 million in 2020. I guess the question I have too with -- from Bill is, in terms of cash flow, finance receivables was about $175 million of cash, I think, in 2019, which I believe was down year over year but still, obviously, was a source of cash, but it was a use in fourth quarter.Referring to the black and white segment in particular in the high end, is that just simply enterprise accounts, lumpiness? For 2020, we expect payments for restructuring of approximately $175 million. We are making progress on our three-year revenue road map as investments in our business gained traction. Is it just simply the lumpiness of that business in the enterprise accounts? And they understand our transaction. Or would it be to kind of go into the summer with the board-level elections?
So the two of those being headwinds, we expect to still overcome those mainly through improvements not only in our cost structure, but also in working capital components of AR, AP.Yes. We are pressing ahead with our pursuit of this acquisition and are already working key elements of an integration plan so that we are well-positioned to execute quickly when and if successful.Adjusted EPS grew $0.39 year over year to $1.33 in the quarter. Full-year revenue declined 4.7% at constant currency year over year, in line with our guidance. Our engineers are working with Alcon to develop new eye care solutions that leverage our existing IP and will help millions of people who struggle with various eye conditions. In 2020, we have approximately $1 billion in bonds maturing and believe we have access to capital resources sufficient to handle upcoming debt maturities. So we looked at the renegotiation of the -- our relationship with Fujifilm, and it's clearly a positive from a supplier perspective. In the fourth quarter, competitive knockouts and new business accounted for more than a third of iIridesse and Baltoro placements. While sales continued to fall, Xerox is focusing on improving its bottom line.Despite a 6.4% drop in sales, analysts expect Xerox to expand EPS by 12.4% in 2019.
And we saw a significant improvement from where we were like, in the first two quarters, 9% to 12% year-over-year decline to significant low single-digit decline in supplies.Yes. This rate of decline was an improvement over the first half, but slightly less than Q3, which included a large transactional IT services sale.
