"With questionable cash flows amounting to only -1.1% of operating cash flow, ONEOK Partners' cash flows look clean. Within the questionable cash flow... other operating activities (which can include deferred income taxes, pension charges, and other one-off items) provided the biggest boost, at 1.8% of cash flow from operations. Overall, the biggest drag on FCF came from capital expenditures, which consumed 61.7% of cash from operations."
I would not say the article was all negative.
The Fools lost a lot of credibility with me when the pumped (then long overstayed) the dot.com bubble.
