Duncan Energy Partners Reports Third Quarter 2010 Results;
Executes $1.25 Billion of Credit Facilities
 
Houston, Texas (October 26, 2010) – Duncan Energy Partners L.P. (NYSE: DEP) today announced its financial and operating results for the three and nine months ended September 30, 2010.  Net income attributable to Duncan Energy Partners for the third quarter of 2010 was $20.6 million, or $0.36 per common unit on a fully diluted basis, compared to $24.8 million, or $0.43 per common unit on a fully diluted basis, for the third quarter of 2009.  Net income attributable to Duncan Energy Partners for the third quarter of 2010 was reduced by aggregate charges totaling $5.2 million, or $0.09 per common unit, associated with litigation related to a pipeline dispute, the liquidation of employee partnerships, and the disposition of a section of non-core natural gas pipeline.
 
The partnership’s distributable cash flow was $33.8 million for the third quarter of 2010 compared to $34.6 million for the third quarter of 2009.  On October 14, 2010, the Board of Directors of Duncan Energy Partners’ general partner declared an increase in the partnership’s quarterly cash distribution rate with respect to the third quarter of 2010 to $0.4525 per common unit, or $1.81 per unit on an annualized basis.  This is a 2.8 percent increase over the $0.44 per unit that was paid with respect to the third quarter of 2009.  The partnership’s share of distributable cash flow for the third quarter of 2010 provides approximately 1.3 times coverage of the cash distribution to be paid on November 8, 2010 to unitholders of record on October 29, 2010.  The partnership reta ined approximately $7.5 million of distributable cash flow in the third quarter of 2010, and $20 million for the first nine months of 2010, which can be used to fund growth capital projects and reduce debt.  Distributable cash flow is a non-generally accepted accounting principle (“non-GAAP”) financial liquidity measure that is defined and reconciled later in this press release to its most directly comparable U.S. GAAP financial measure, which is net cash flows provided by operating activities.
 
On October 25, 2010, Duncan Energy Partners executed $1.25 billion of senior unsecured credit facilities comprised of an $850 million revolving credit facility and a $400 million senior term loan facility, both of which mature in October 2013.  Proceeds from these facilities will be used for general partnership purposes, including the termination and repayment of the existing $300 million revolving credit facility and the $200 million revolving credit facility from a subsidiary of Enterprise Products Partners L.P. (“Enterprise”).
 
“Our partnership reported record gross operating margin this quarter,” said W. Randall Fowler, president and chief executive officer of the general partner of Duncan Energy Partners.  “We continue to benefit from near record volumes and higher capacity reservation fees from our natural gas and NGL pipelines and storage.  Cash flow from our fee-based assets enabled us to increase the cash distribution to our partners for the eighth consecutive quarter while providing solid coverage of the cash distributions.”
 
Fowler continued, “We are very pleased with the strong support from our bank group.  We expect these credit facilities will provide the liquidity and the financial flexibility to substantially fund our portion of the Haynesville Extension Pipeline project, which is progressing on budget and on schedule to be in full service in September 2011.”

Review of Segment Quarterly Performance
 
Since Duncan Energy Partners consolidates the financial results of its controlled operating subsidiaries, the following discussion of segment results reports gross operating margin and volumes on a 100 percent basis, even though the partnership owns less than 100 percent of these businesses.  Gross operating margin is a non-GAAP financial performance measure that is defined and reconciled later in this press release to its most directly comparable GAAP financial measure, which is operating income.
 
Natural Gas Pipelines & Services – Gross operating margin for the third quarter of 2010 increased 14 percent to $46.3 million from $40.5 million for the third quarter of 2009.  Gross operating margin from the Texas Intrastate System for the third quarter of 2010 was $8.2 million higher than the third quarter of 2009, primarily due to higher firm capacity reservation fees earned by the Sherman Extension pipeline.  The Sherman Extension pipeline commenced operations and began earning firm capacity reservation fees in August 2009.  An increase in gross operating margin on the Texas Intrastate System was partially offset by lower natural gas sales margins and throughput volumes on the Acadian system.
 
Total natural gas throughput volumes averaged 4.9 trillion British thermal units per day (“TBtud”) in the third quarter of 2010 compared to 4.7 TBtud in the third quarter of 2009.
 
NGL Pipelines & Services – Gross operating margin for the third quarter of 2010 was $25.5 million compared to $28.3 million for the third quarter of 2009.  Excluding operational measurement gains and losses associated with the partnership’s Mont Belvieu NGL and petrochemical storage facility that are allocated to Enterprise through noncontrolling interest, gross operating margin was $22.9 million for the third quarter of 2010 compared to $27.5 million for the third quarter of 2009.  Gross operating margin this quarter benefited from increased storage fees and volumes at the partnership’s complex in Mont Belvieu, Texas as well as increased NGL fractionation and pipeline transportation volumes in south Texas.  Offsetting these ben efits to gross operating margin for the third quarter of 2010 is a $6.8 million charge related to a dispute on our South Texas NGL pipeline system that occurred prior to the pipeline’s acquisition in September 2004.
 
“In November 2010, the conversion of the first of two NGL caverns to store refined products at our Mont Belvieu complex will be completed.  We expect to earn higher fees from these caverns in refined product service,” Fowler said.
 
NGL transportation volumes increased 19 percent to 125 thousand barrels per day (“MBPD”) in the third quarter of 2010 from 105 MBPD in the third quarter of 2009.  NGL fractionation volumes averaged 80 MBPD in the third quarter of 2010 compared to 74 MBPD in the third quarter of 2009.
 
Petrochemical Services – Gross operating margin for the third quarter of 2010 decreased to $2.6 million from $2.8 million for the third quarter of 2009, due to increased operating expenses, primarily for pipeline integrity costs on the Lou-Tex Propylene Pipeline in the third quarter of 2010.  Partially offsetting the decrease in gross operating margin this quarter was increased revenues from higher petrochemical transportation volumes, which increased 14 percent to 40 MBPD for the third quarter of 2010 from 35 MBPD for the third quarter of 2009.
 
In addition to the changes in segment gross operating margin discussed above, operating income for the third quarter of 2010 was impacted by a $9.1 million non-cash loss from the disposition of a natural gas pipeline segment in the Eagle Ford Shale that was no longer deemed a part of the partnership’s strategic plans.
 
Capitalization
 
Total debt principal outstanding was $655 million at September 30, 2010.  Duncan Energy Partners had total liquidity of approximately $140 million at September 30, 2010 including availability under the partnership’s revolving credit facilities and cash.  Liquidity for Duncan Energy Partners would have been approximately $860
 
 
2

 
 
million at September 30, 2010 after adjusting for the execution of the $1.25 billion credit facilities and the repayment of existing revolving credit facilities.
 
Total capital spending in the third quarter of 2010 was approximately $304 million, which included approximately $198 million spent on the Haynesville Extension Pipeline project and $12 million for sustaining capital expenditures.  For the first nine months of this year, the partnership had $643 million in capital expenditures, including approximately $336 million for the Haynesville Extension Pipeline and $41 million of sustaining capital expenditures.
 
Supplemental Selected Standalone Financial Information
 
In February 2007, Duncan Energy Partners acquired controlling ownership interests in five midstream energy companies (the “DEP I Midstream Businesses”) from Enterprise in a drop down transaction.  In December 2008, Duncan Energy Partners acquired controlling ownership interests in three additional midstream energy companies (the “DEP II Midstream Businesses”) from Enterprise in a second drop down transaction.
 
To assist investors and other users of our financial statements, Exhibit A to this press release includes selected financial information of Duncan Energy Partners L.P. on a standalone basis apart from that of our consolidated partnership financial information.  A key difference between the supplemental selected standalone financial information and our general purpose consolidated financial statements is that the DEP I and DEP II Midstream Businesses (i.e., the partnership’s operating subsidiaries) are viewed as investments and presented as unconsolidated affiliates by Duncan Energy Partners L.P. on a standalone basis.
 
Use of Non-GAAP Financial Measures
 
This press release includes the non-GAAP financial measures of gross operating margin and distributable cash flow.  The exhibits accompanying this press release provide reconciliations of these non-GAAP financial measures to their most directly comparable financial measures calculated and presented in accordance with GAAP.  Our non-GAAP financial measures should not be considered as alternatives to GAAP measures such as net income, operating income, net cash flows provided by operating activities or any other GAAP measure of financial performance or liquidity.  Our non-GAAP financial measures may not be comparable to similarly-titled measures of other companies because they may not calculate such measures in the same manner as we do.
 
Gross operating margin.  We evaluate segment performance based on the non-GAAP financial measure of gross operating margin.  Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations.  This measure forms the basis of our internal financial reporting and is used by management in deciding how to allocate capital resources among business segments.  We believe that investors benefit from having access to the same financial measures that management uses in evaluating segment results.  The GAAP financial measure most directly comparable to total segment gross operating margin is operating income.
 
We define total segment gross operating margin as operating income before: (i) depreciation, amortization and accretion expense; (ii) non-cash consolidated asset impairment charges; (iii) gains and losses from asset sales and related transactions; and (iv) general and administrative costs.  Gross operating margin by segment is calculated by subtracting segment operating costs and expenses (net of the adjustments noted above) from segment revenues, with both segment totals before the elimination of any intersegment and intrasegment transactions.  In accordance with GAAP, intercompany accounts and transactions are eliminated in consolidation.  Gross operating margin is exclusive of other income and expense transactions, provision for income taxes, extraordinary charges and the cumulative effect of ch anges in accounting principles.  Gross operating margin is presented on a 100 percent basis before the allocation of earnings to noncontrolling interests.

Distributable cash flow.  The partnership’s distributable cash flow is a useful non-GAAP measure of liquidity that approximates the amount of cash that Duncan Energy Partners could pay its partners each period.  We define the partnership’s distributable cash flow as the sum of its share of the distributable cash flow of each of the DEP I and DEP II Midstream Businesses, less any standalone expenses of the partnership such as interest expense and general and administrative costs (net of non-cash items).
 
In general, we define the distributable cash flow of our operating subsidiaries as their net income or loss adjusted for:
 
§  
the addition of depreciation, amortization and accretion expense;
§  
the addition of cash distributions received from Evangeline, if any, less equity earnings;
§  
the subtraction of sustaining capital expenditures and cash payments to settle asset retirement obligations;
§  
the addition of losses or subtraction of gains relating to asset sales and related transactions;
§  
the addition of cash proceeds from asset sales and related transactions;
§  
the addition of losses or subtraction of gains from the monetization of derivative instruments recorded in accumulated other comprehensive income (loss), if any, less related amortization of such amounts to earnings; and
§  
the addition or subtraction of other miscellaneous non-cash amounts (as applicable) that affect net income or loss for the period.
 
Sustaining capital expenditures are capital expenditures (as defined by GAAP) resulting from improvements to and major renewals of existing assets.  Such expenditures do not generate additional revenues.
 
Management compares our distributable cash flow to the cash distributions we expect to pay our partners.  Using this data, management computes our distribution coverage ratio.  Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is in part measured by its yield, which is based on the amount of cash distributions a partnership pays to a unitholder.  The GAAP measure most directly comparable to distributable cash flow is net cash flows provided by operating activities.
 
Third Quarter 2010 Earnings Conference Call
 
Management for Duncan Energy Partners will discuss third quarter results with analysts and investors in a combined conference call with Enterprise Products Partners scheduled for 9 a.m. CDT today.  The call will be broadcast live over the Internet and may be accessed by visiting the partnership’s website at www.deplp.com.
