EXHIBIT 99.1 NORTHERN BORDER PARTNERS, L.P. REVISES INITIALLY RELEASED 2001 NET INCOME FOR IMMEDIATE RELEASE: Monday, March 11, 2002 OMAHA - Northern Border Partners, L.P. (NYSE - NBP) today announced it is revising its initially released fourth quarter and full year 2001 net income to $20.3 million or $0.45 per unit, and $87.8 million or $2.12 per unit, respectively. The revision relates to noncash adjustments in accounting for certain commodity hedges of Bear Paw Energy, the Partnership's U.S. gathering and processing segment. In 2001 Bear Paw Energy entered into swap agreements with Enron North America (ENA), a subsidiary of Enron Corp., to hedge a portion of its share of the natural gas and natural gas liquids expected to be received as processing fees in 2001 to 2005. During the fourth quarter of 2001, the hedging relationships were discontinued due to concerns over the liquidity of ENA. Previously, the Partnership believed that the change in the market value of the swaps due to the ENA bankruptcy would result in a reduction in future income recognition over the term of the swaps. However, under generally accepted accounting principles, income from these agreements will continue to be recognized over their original term and the $5.3 million loss in the value of the hedge will be charged to net income in 2001. "The rules regarding accounting for these financial instruments are complex and evolving," said Bill Cordes, chairman and chief executive officer of Northern Border Partners. "This does not change the estimate of our exposure to ENA, which has been fully reserved to-date. The overall effect of this revision is to move $5.3 million of income from 2001 or $0.12 per unit to the years 2002 through 2005, with just over $4.6 million related to the year 2002. Cash flow is not impacted. It is also important to note this is a change in the preliminary earnings information released in January only and not a restatement of financial statements previously filed with the SEC. We continue to expect to file our Form 10-K on a timely basis." Northern Border Partners will host an analyst conference call to discuss this revision on Tuesday, March 12, 2002 at 8:30 am EST. The Partnership will also simulcast the call live via the Internet at http://www.northernborderpartners.com. A replay of the call will be available through Tuesday, March 19, 2002 by dialing, toll free, (888) 203-1112 and entering confirmation code 759631. The call will also be archived on the Northern Border Partners' website.

This press release includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Although Northern Border Partners, L.P. believes that its expectations are based on reasonable assumptions, it can give no assurance that such expectations will be achieved. Important factors that could cause actual results to differ materially from those in the forward-looking statements include developments in the voluntary petitions for bankruptcy by Enron; natural gas developments in the Powder River, Wind River, Williston and Western Canadian Sedimentary Basins; regulatory actions; competitive conditions in the overall natural gas and electricity markets; prices of natural gas and natural gas liquids; and conditions in the capital markets. ## FINANCIAL HIGHLIGHTS (Unaudited: In Millions Except Net Income Per Unit) <Table> <Caption> FOURTH QUARTER YEAR-TO-DATE 2001 2000 2001 2000 -------------- ------------- -------------- ------------- Operating Revenue $123.4 $92.1 $461.5 $339.7 Recurring Net Income $20.3 $20.4 $92.6 $76.7 Per Unit Recurring Net Income $0.45 $0.65 $2.24 $2.50 Cash Flows From Operating Activities $72.3 $23.2 $233.9 $169.6 EBITDA* $76.1 $70.1 $303.0 $259.3 CONSOLIDATED STATEMENT OF INCOME (Unaudited: In Millions Except Net Income Per Unit) <Table> <Caption> FOURTH QUARTER YEAR-TO-DATE 2001 2000 2001 2000 -------------- ------------- -------------- ------------- Operating Revenue $123.4 $92.1 $461.5 $339.7 -------------- ------------- -------------- ------------- Operating Expenses Product Purchases 10.0 0.0 39.7 0.0 Operations and Maintenance 32.4 20.7 96.5 62.1 Depreciation and Amortization 20.6 14.8 76.3 60.7 Taxes Other Than Income 7.1 6.4 28.1 28.6 -------------- ------------- -------------- ------------- Total Operating Expenses 70.1 41.9 240.6 151.4 -------------- ------------- -------------- ------------- Operating Income 53.3 50.2 220.9 188.3 Interest Expense, Net (22.1) (23.0) (91.1) (81.5) Other Income (Expense) (0.2) 3.1 (1.6) 8.6 Equity Earnings (Losses) from Investments 0.5 0.5 1.7 (0.6) Minority Interest (11.2) (10.4) (42.1) (38.1) -------------- ------------- -------------- ------------- Net Income $20.3 $20.4 $87.8 $76.7 Non-Recurring Items 0.0 0.0 (4.8) 0.0 -------------- ------------- -------------- ------------- Recurring Net Income $20.3 $20.4 $92.6 $76.7 ============== ============= ============== ============= EBITDA* $76.1 $70.1 $303.0 $259.3 ============== ============= ============== ============= Per Unit Net Income $0.45 $0.65 $2.12 $2.50 ============== ============= ============== ============= Per Unit Recurring Net Income $0.45 $0.65 $2.24 $2.50 ============== ============= ============== ============= Average Units Outstanding 41.6 30.6 38.5 29.7 ============== ============= ============== ============= * Represents net income plus minority interest, interest expense, net, income taxes and depreciation and amortization including goodwill amortization netted against equity earnings (losses) from investments, less equity AFUDC.
