ONEOK Named a Top Performer on CFO Magazine's Annual Capital Spending Scorecard

April 09, 2007

TULSA, Okla., April 9, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- ONEOK, Inc. (NYSE: OKE) announced today that it was named a top performer in its industry in CFO magazine's 2006 Capital Spending Scorecard. ONEOK tied for first in its category based on adjusted return on gross fixed assets (ROGFA).

ONEOK posted an adjusted return on gross fixed assets of 18 percent in 2005 and a compound annual return of 16 percent for shareholders over the three-year period ending in 2005.

"We have long believed that how well we spend our capital is more important than how much we spend," said John W. Gibson, chief executive officer of ONEOK. "This is one more indicator of our strong commitment to delivering value to our shareholders."

CFO magazine ranked the 20 largest companies in 15 capital-intensive industries by ROGFA, which roughly equates to the ratio of operating profits to capital spending. It ranked companies in each industry according to their 2005 earnings before interest, taxes, depreciation, and amortization divided by the book value of their fixed assets, and adjusted to eliminate the balance-sheet effect of operating leases.

The resulting ratio, ROGFA, reflects how much a company earns on its property, plant, and equipment. In many industries, a high ROGFA correlates with strong performance in other key areas, such as sales growth and shareholder return, according to CFO magazine.
