Duncan Energy Partners Reports Results
For Second Quarter 2010
 
Houston, Texas (July 26, 2010) – Duncan Energy Partners L.P. (NYSE: DEP) today announced its financial and operating results for the three and six months ended June 30, 2010.  Net income attributable to Duncan Energy Partners for the second quarter of 2010 was $23.3 million, or $0.40 per common unit on a fully diluted basis, compared to $23.2 million, or $0.40 per common unit on a fully diluted basis, for the second quarter of 2009.
 
The partnership’s distributable cash flow increased to $32.8 million for the second quarter of 2010 from $32.3 million for the second quarter of 2009.  Of these amounts, the DEP II Midstream Businesses provided $22.0 million of distributable cash flow in the second quarter of 2010 compared to $21.7 million in the second quarter of 2009.  Distributable cash flow for the first six months of 2010 was $64.8 million compared to $61.8 million for the first six months of 2009.
 
On July 13, 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 second quarter of 2010 to $0.45 per common unit, or $1.80 per unit on an annualized basis.  This is a 3.4 percent increase over the $0.435 per unit that was paid with respect to the second quarter of 2009.  The partnership’s share of distributable cash flow for the second quarter of 2010 provides approximately 1.3 times coverage of the cash distribution to be paid on August 6, 2010 to unitholders of record on July 30, 2010.  The partnership retained approximately $7 million of distributable cash flow in the second quarter of 2010, and $13 million for the first six months of 2010, which can be used to fund g rowth 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.
 
“We are pleased to report another solid quarter for Duncan Energy partners,” said W. Randall Fowler, president and chief executive officer of the general partner of Duncan Energy Partners.  “Our platform of fee-based assets enabled us to increase the cash distribution to our partners for the seventh consecutive quarter.  We continue to benefit from higher revenues from our pipeline and storage assets.”
 
“The expansion of the Acadian natural gas pipeline system (the Haynesville Extension) is proceeding on schedule.  We have locked-in our steel costs, nearly completed all of the survey and permitting work and acquired approximately one-third of the right of way.  We expect most of the capital spending for this project to begin late this year and in 2011.  The expected completion date for the Haynesville Extension is the end of the third quarter of 2011.  We are excited about this project as producers continue to have a great deal of success in developing the Haynesville and Bossier shale plays in North Louisiana and East Texas,” stated Fowler.
 
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
 
1
 
 

 

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 second quarter of 2010 increased 23 percent to $37.1 million from $30.2 million for the second quarter of 2009.  Gross operating margin from the Texas Intrastate System for the second quarter of 2010 was $8.2 million higher than the second quarter of 2009, primarily due to higher firm capacity reservation fees of $14.5 million, largely attributable to the Sherman Extension pipeline.  This increase in gross operating margin was partially offset by lower throughput volumes on other segments of the Texas Intrastate System.
 
Total natural gas throughput volumes averaged 4.6 trillion British thermal units per day (“TBtud”) in the second quarter of 2010 compared to 4.7 TBtud in the second quarter of 2009.
 
NGL Pipelines & Services – Gross operating margin for the second quarter of 2010 increased to $31.6 million from $24.2 million for the second quarter of 2009.  Net of operational measurement gains and losses associated with the partnership’s Mont Belvieu NGL and petrochemical storage facility that are allocated to Enterprise Products Partners L.P. (“Enterprise”) through noncontrolling interest, gross operating margin increased 10 percent to $28.1 million for the second quarter of 2010 from $25.5 million for the second quarter of 2009.  This increase in gross operating margin was primarily due to higher revenues attributable to increased storage fees and volumes at the partnership’s complex in Mont Belvieu, Texas.
 
NGL transportation volumes increased to 112 thousand barrels per day (“MBPD”) in the second quarter of 2010 from 106 MBPD in the second quarter of 2009.  NGL fractionation volumes decreased to 66 MBPD in the second quarter of 2010 from 77 MBPD in the second quarter of 2009.  Fractionation volumes were lower during the second quarter of 2010 as a result of scheduled downtime at our Shoup NGL fractionator for maintenance and facility expansion projects in anticipation of an increase in NGL production from the Eagle Ford shale.
 
Petrochemical Services – Gross operating margin reported for the second quarter of 2010 increased to $2.8 million from $2.6 million for the second quarter of 2009. Total petrochemical transportation volumes increased 32 percent to 37 MBPD for the second quarter of 2010 from 28 MBPD for the second quarter of 2009, primarily due to higher volumes transported on the Lou-Tex propylene pipeline.
 
Capitalization
 
Total debt principal outstanding at June 30, 2010 was $537 million.  At June 30, 2010, Duncan Energy Partners had total liquidity of approximately $260 million, which includes availability under the partnership’s revolving credit facilities and cash.
 
Total capital spending in the second quarter of 2010 was approximately $221 million, which was primarily for the Haynesville Extension Pipeline project.  Included in total capital spending was $18 million for 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 chan ges 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.
 
Second Quarter 2010 Earnings Conference Call
 
Management for Duncan Energy Partners will discuss second quarter results with analysts and investors on a combined conference call with Enterprise scheduled for 8:00 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.

Supplemental Standalone Financial Information - UNAUDITED
For the Three and Six Months Ended June 30, 2010 and 2009
(Amounts in millions, except per unit figures)

The following table summarizes the distributable cash flow (“DCF”) and related coverage ratio calculations for Duncan Energy Partners on a standalone basis.  The line item captioned “Duncan Energy Partners L.P. standalone expenses, net of non-cash items” primarily represents accrued interest expense and general and administrative costs of the partnership itself, exclusive of any such amounts attributable to the DEP I and DEP II Midstream Businesses.  We calculate the distribution coverage ratio by dividing “Distributable cash flow, net to limited partners” by the average number of distribution-bearing units outstanding, and further by the declared distribution rate per unit for the period indicated.

In addition, the following table presents selected income statement and balance sheet data of Duncan Energy Partners L.P. on a standalone basis.  Duncan Energy Partners L.P. currently has no operations apart from its investments in the DEP I and DEP II Midstream Businesses.  For purposes of this presentation, we have listed amounts pertaining to the DEP I Midstream Businesses apart from those relating to the DEP II Midstream Businesses.
