Notes to Condensed Consolidated Financial Statements (Unaudited)
1. Unaudited Interim Financial Information.
The condensed consolidated financial statements have not been audited. These financial statements should be read in conjunction with the Consolidated Financial Statements and Notes included in our Form 10-K for the year ended October 31, 2006.
          Seasonality and Use of Estimates.
In our opinion, the unaudited condensed consolidated financial statements include all normal recurring adjustments necessary for a fair statement of financial position at April 30, 2007 and October 31, 2006, the results of operations for the three months and six months ended April 30, 2007 and 2006, and cash flows for the six months ended April 30, 2007 and 2006. Our business is seasonal in nature. The results of operations for the three months and six months ended April 30, 2007 do not necessarily reflect the results to be expected for the full year.
We make estimates and assumptions when preparing the condensed consolidated financial statements. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from estimates.
          Significant Accounting Policies.
Our accounting policies are described in Note 1 to our Annual Report on Form 10-K for the year ended October 31, 2006. There were no significant changes to those accounting policies during the six months ended April 30, 2007.
          Rate-Regulated Basis of Accounting.
We follow Statement of Financial Accounting Standards (SFAS) No. 71, “Accounting for the Effects of Certain Types of Regulation” (Statement 71). Statement 71 provides that rate-regulated public utilities account for and report assets and liabilities consistent with the economic effect of the manner in which independent third-party regulators establish rates. In applying Statement 71, we capitalize certain costs and benefits as regulatory assets and liabilities, respectively, in order to provide for recovery from or refund to utility customers in future periods. The amounts recorded as regulatory assets in the condensed consolidated balance sheets as of April 30, 2007 and October 31, 2006, were $94.4 million and $143.5 million, respectively. The amounts recorded as regulatory liabilities in the condensed consolidated balance sheets as of April 30, 2007 and October 31, 2006, were $347.9 million and $337 million, respectively.
Significant inter-company transactions have been eliminated in consolidation where appropriate; however, we have not eliminated inter-company profit on sales to affiliates and costs from affiliates in accordance with Statement 71. See Note 7 to the condensed consolidated financial statements for information on related party transactions.

          Recent Accounting Pronouncements.
In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, “Accounting for Uncertainty in Income Taxes” (FIN 48), to clarify the accounting for uncertain tax positions in accordance with SFAS 109, “Accounting for Income Taxes,” and in May 2007 issued Staff Position 48-1, “Definition of Settlement in FASB Interpretation No. 48,” (FSP 48-1). FIN 48 defines a minimum recognition threshold that a tax position must meet to be recognized in an enterprise’s financial statements. Additionally, FIN 48 provides guidance on derecognition, measurement, classification, interim period accounting, disclosure and transition requirements in accounting for uncertain tax positions. FSP 48-1 clarifies when a tax position is considered effectively settled under FIN 48. FIN 48 is effective the beginning of the first annual period beginning after December 15, 2006, and the guidance under FSP 48-1 should be applied upon the adoption of FIN 48. Accordingly, we will adopt FIN 48 and FSP 48-1 in our fiscal year 2008. We are currently assessing the impact FIN 48 may have on our consolidated financial statements; however, we believe the adoption of FIN 48 will not have a material impact on our financial position, results of operations or cash flows.
In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (Statement 157). Statement 157 provides enhanced guidance for using fair value to measure assets and liabilities and applies whenever other standards require (or permit) the measurement of assets or liabilities at fair value, but does not expand the use of fair value measurement to any new circumstances. Statement 157 establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, for example, the reporting entity’s own data. Under Statement 157, fair value measurements would be separately disclosed by level within the fair value hierarchy. Statement 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, with earlier application encouraged. Accordingly, we will adopt Statement 157 no later than our first fiscal quarter in 2009. We believe the adoption of Statement 157 will not have a material impact on our financial position, results of operations or cash flows.
In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (Statement 158). Statement 158 requires an employer to fully recognize the obligations associated with single-employer defined benefit pension, retiree healthcare and other postretirement plans in the financial statements by recognizing in its statement of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status rather than only disclosing the funded status in the footnotes to the financial statements. Statement 158 requires employers to recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. Under Statement 158, gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit cost will be recognized in accumulated other comprehensive income (OCI), net of tax effects, until they are amortized as a component of net periodic cost. Statement 158 also requires that the company measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year. We are already in compliance with this requirement as our pension plans’ measurement dates are already the same as our fiscal year end date.
The requirement to recognize the funded status of a benefit plan and the related disclosure requirements initially will apply as of the end of the fiscal year ending after December 15, 2006. Accordingly, we will adopt the funded status portion of Statement 158 as of October 31, 2007. We believe the adoption of Statement 158 will not have a material effect on our financial position, results of operations or cash flows.
Based on a preliminary assessment of prior regulatory treatment of postretirement benefits, management believes that regulatory asset or liability treatment will be afforded to any amounts that would otherwise be recorded in accumulated OCI resulting from the implementation of Statement 158. We intend to meet with

Table of Contents

our regulators in fiscal year 2007 to discuss the regulatory accounting and rate treatment of the impact of the adoption of Statement 158. Assuming regulatory treatment, if Statement 158 had been adopted for the fiscal year ended October 31, 2006, the effect on the consolidated balance sheets would have been the recognition of $25.6 million as a regulatory asset, $16.7 million of deferred income taxes, $14.6 million decrease to prepaid pension and $27.7 million increase in accrued postretirement benefits. The actual impact at October 31, 2007 could be substantially different depending on the discount rate, asset returns and plan population at that date.
In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (Statement 159). Statement 159 provides companies with an option to report selected financial assets and liabilities at fair value. Its objective is to reduce the complexity in accounting for financial instruments and to mitigate the volatility in earnings caused by measuring related assets and liabilities differently. Although Statement 159 does not eliminate disclosure requirements included in other accounting standards, it does establish additional presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. Statement 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, with early adoption permitted for an entity that has elected also to apply Statement 157 early. Accordingly, we will adopt Statement 159 no later than our first fiscal quarter in 2009. We believe the adoption of Statement 159 will not have a material impact on our financial position, results of operations or cash flows.
2. Regulatory Matters.
In North Carolina and South Carolina, recoveries of gas costs are subject to annual gas cost recovery proceedings to determine the prudence of our gas purchases. We have been found prudent in all such past proceedings.
On May 31, 2007, we reached a settlement with the staff of the Tennessee Regulatory Authority (TRA) and the Consumer Advocate Division (CAD) of the Tennessee Attorney General’s Office, which, if approved by the TRA would modify our Tennessee Incentive Plan (TIP). The TIP settlement would clarify and simplify the calculation of allocated gains and losses to ratepayers and shareholders by adopting a uniform 75/25 sharing ratio, maintain the current $1.6 million annual incentive cap on gains and losses under the plan, improve the transparency of plan operations by specifying the request for proposal procedures for asset management transactions and provide for a triennial review of TIP operations by an independent consultant. The settlement was filed on June 4, 2007 with the TRA for approval.
3. Accelerated Share Repurchase Program.
On March 30, 2007, we entered into an accelerated share repurchase (ASR) agreement where we purchased 850,000 shares of our common stock from an investment bank at the closing price that day of $26.38 per share. The settlement and retirement of those shares occurred on April 2, 2007. Total consideration paid to purchase the shares of $22.5 million, including $25,500 in commissions and structuring fees, was recorded in “Stockholders’ equity” as a reduction in “Common stock.”
As part of the accelerated share repurchase, we simultaneously entered into a forward sale contract with the investment bank that was expected to mature in approximately 50 trading days. Under the terms of the forward sale contract, the investment bank is required to purchase, in the open market, 850,000 shares of our common stock during the term of the contract to fulfill its obligation related to the shares it borrowed from third parties and sold to us. At settlement, we, at our option, are required to either pay cash or issue registered

or unregistered shares of our common stock to the investment bank if the investment bank’s weighted average purchase price is higher than the March 30, 2007, closing price. The investment bank is required to pay us either cash or shares of our common stock, at our option, if the investment bank’s weighted average price for the shares purchased is lower than the March 30, 2007, closing price. The amount of the payment is the difference between the investment bank’s weighted average price per share and $26.38 per share multiplied by 850,000 shares.
We accounted for the forward sale contract as an equity instrument under the provisions of Emerging Issues Task Force (EITF) Issue No. 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock.” As the fair value of the forward sale contract at inception was zero, no accounting for the forward sale contract is required until settlement, as long as the forward sale continues to meet the requirements for classification as an equity instrument. As of April 30, 2007, the investment bank had purchased 505,200 shares at a cumulative weighted average price of $26.9498 per share.
Subsequent to the quarter ended April 30, 2007, the investment bank purchased the remaining 344,800 shares, which resulted in a cumulative weighted average price of $26.8459 per share for the entire 850,000 shares repurchased. At settlement on May 23, 2007, we paid cash of $.4 million to the investment bank and recorded this amount in “Stockholders’ equity” as a reduction in “Common stock.” The $.4 million was the difference between the investment bank’s weighted average purchase price of $26.8459 and the March 30, 2007, closing price of $26.38 per share multiplied by 850,000 shares.
4. Earnings Per Share.
We compute basic earnings per share using the weighted average number of shares of common stock outstanding during each period. A reconciliation of basic and diluted earnings per share for the three months and six months ended April 30, 2007 and 2006 is presented below.

6. Business Segments.
We have two reportable business segments, regulated utility and non-utility activities. These segments were identified based on products and services, regulatory environments and our corporate organization and business decision-making activities. Operations of our regulated utility segment are conducted by the parent company. Operations of our non-utility activities segment are comprised of our equity method investments in joint ventures.
Operations of the regulated utility segment are reflected in operating income in the condensed consolidated statements of income. Operations of the non-utility activities segment are included in the condensed consolidated statements of income in “Income from equity method investments.”
We evaluate the performance of the regulated utility segment based on margin, operations and maintenance expenses and operating income. We evaluate the performance of the non-utility activities segment based on earnings from the ventures. The basis of segmentation and the basis of the measurement of segment profit or

We own 30% of the membership interests in SouthStar Energy Services LLC, a Delaware limited liability company. Under the terms of the Amended and Restated Limited Liability Company Agreement (Restated Agreement), earnings and losses are allocated 25% to us and 75% to the other member, Georgia Natural Gas Company (GNGC), a subsidiary of AGL Resources, Inc., with the exception of earnings and losses in the Ohio and Florida markets, which are allocated to us at our ownership percentage of 30%. SouthStar primarily sells natural gas to residential, commercial and industrial customers in the southeastern United States, with most of its business being conducted in the unregulated retail gas market in Georgia. We have related party transactions as a wholesale gas supplier to SouthStar, and we record in operating revenues the amounts billed to SouthStar. Our operating revenues from these sales for the three months and six months ended April 30, 2007 and 2006, are presented below.

The SouthStar Restated Agreement mentioned above contains provisions providing for the disposition of ownership interests between members, including a provision granting three options to GNGC to purchase our ownership interest in SouthStar. By notice no later than November 1, 2007, with the option effective on January 1, 2008 (2008 option), GNGC has the option to purchase one-third of our 30% interest in SouthStar. With the same notice in the following years, GNGC has the option to purchase 50% of our interest to be effective on January 1, 2009 (2009 option), and 100% of our interest to be effective on January 1, 2010. The purchase price would be based on the market value of SouthStar as defined in the Restated Agreement.
If GNGC exercises either the 2008 option or the 2009 option, we, at our discretion, may cause GNGC to purchase our entire ownership interest.
For further information on this provision, please see the Restated Agreement that was filed with the Securities

and Exchange Commission (SEC) as Exhibit 10.1 in our Form 10-Q for the quarter ended April 30, 2004.
Piedmont Hardy Storage Company, LLC (Piedmont Hardy), a wholly-owned subsidiary of Piedmont, owns 50% of the membership interests in Hardy Storage Company, LLC (Hardy Storage), a West Virginia limited liability company. The other owner is a subsidiary of Columbia Gas Transmission Corporation, a subsidiary of NiSource Inc. Hardy Storage owns and operates an underground interstate natural gas storage facility located in Hardy and Hampshire Counties, West Virginia, that is regulated by FERC. Service to customers began April 1, 2007 in the initial service phase and Hardy Storage continues to pursue construction related to subsequent phases of the project. On June 29, 2006, Hardy Storage signed a note purchase agreement for interim notes and a revolving equity bridge facility for up to a total of $173.1 million for funding during the construction period. After the satisfaction of certain conditions in the note purchase agreement, the two members of Hardy Storage will pay off 30% of the construction financing with their equity contributions and the remaining 70% debt will convert to a fifteen-year mortgage-style debt instrument without recourse to the members. We expect the conversion to occur in late spring to summer of 2008. In April 2007, the other member of Hardy Storage contributed assets as part of its share of the 30% owner contributions. Our corresponding share, which will be payable when permanent financing is obtained, is $12.9 million.
Prior to the conversion of the construction loan to permanent financing, the members of Hardy Storage have each agreed to guarantee 50% of the construction financing. The guaranty was executed by Piedmont Energy Partners, Inc. (PEP), a wholly-owned subsidiary of Piedmont and a sister company of Piedmont Hardy. Our share of the guaranty is capped at $111.5 million. Depending upon the facility’s performance over the first three years after the in-service date, there could be additional construction expenditures of up to $10 million, of which PEP will guarantee 50%.
Securing PEP’s guaranty is a pledge of intercompany notes issued by Piedmont held by non-utility subsidiaries of PEP. Should Hardy Storage be unable to perform its payment obligation under the construction financing, PEP will call on Piedmont for the payment of the notes, plus accrued interest, for the amount of the guaranty. Also pledged is our membership interest in Hardy Storage.
We are recording a liability at fair value for this guaranty based on the probability of project failure applied to 50% of the construction financing outstanding at the end of each quarter, with a corresponding increase to our investment account in the venture. As our risk in the project changes, the fair value of the guaranty is adjusted accordingly through a quarterly evaluation.
As of April 30, 2007, $113.9 million was outstanding under the construction loan, and we have recorded a guaranty liability of $1.7 million. Subsequent to the end of the quarter, an additional $4.9 million became outstanding under the construction financing.
On October 26, 2006, Hardy Storage filed an application with the FERC, for an amendment to its certificate of public convenience and necessity for approval of a settlement that establishes revised initial rates based on updated cost estimates. The estimated cost of the project as refiled with the FERC was $164 million, an increase of $43 million from the original application of $121 million, due to higher costs for skilled labor, material and equipment for the project. This application was approved by the FERC on March 15, 2007.
We have related party transactions as a customer of Hardy Storage beginning in April 2007, and we record in cost of gas the storage costs charged to us by Hardy Storage. These gas costs for the three months and six months ended April 30, 2007 and 2006, are presented below.

As of April 30, 2007, we owed Hardy Storage $.8 million.
8. Financial Instruments.
We have a syndicated five-year revolving credit facility with aggregate commitments totaling $350 million, that may be increased up to $600 million, and that includes annual renewal options. This facility includes letters of credit. We pay an annual fee of $35,000 plus six basis points for any unused amount up to $350 million. The facility provides a line of credit for letters of credit up to $5 million. The credit facility bears interest based on the 30-day LIBOR rate plus from .15% to .35%, based on our credit ratings. At April 30, 2007 and October 31, 2006, outstanding short-term borrowings under the line as included in “Notes payable” in the condensed consolidated balance sheets were $29.5 million and $170 million, respectively. During the three months ended April 30, 2007, short-term borrowings ranged from zero to $230.5 million, and when borrowing under the facility, the actual interest rate for all borrowings, and the weighted average interest rate was 5.57%. During the six months ended April 30, 2007, short-term borrowings ranged from zero to $280.5 million, and when borrowing, interest rates ranged from 5.57% to 5.6% (weighted average of 5.58%). Our credit facility’s financial covenants require us to maintain a ratio of total debt outstanding, including letters of credit and guarantees of debt, to total capitalization of no greater than 70%, and our actual ratio was 48% at April 30, 2007.
We have purchased and sold financial derivative instruments for natural gas in all three states for our gas purchase portfolios. The prudently incurred gains or losses on financial derivatives utilized in the regulated utility segment are included in our rates to customers. Current period changes in the assets and liabilities from these risk management activities are recorded as a component of gas costs in amounts due customers in accordance with Statement 71. Accordingly, there is no earnings impact on the regulated utility segment as a result of the use of these financial derivatives. The fair value of gas purchase options increased from $3.1 million as of October 31, 2006, to $8.8 million as of April 30, 2007, primarily due to options being exercised or options expiring during the period and an increase in the market values of the financial derivative instruments held at April 30, 2007.
9. Restructuring.
On April 13, 2006, we announced plans to restructure our management group at an estimated one-time cost of $7 to $8 million. The restructuring plans are part of an ongoing, larger effort aimed at streamlining business processes, capturing operational and organizational efficiencies and improving customer service. The restructuring began with an offer of early retirement for 23 employees in our management group, and eventually included the further consolidation and reorganization of management positions and functions that was completed in July 2006.
Since April 2006, we have recognized a liability and expense of $7.8 million, which was included in operations and maintenance expense for the cost of the restructuring program. This liability included early retirement for 22 employees of the management group and severance for 17 additional employees through further consolidation. Due to the short discount period, the liability for the program was recorded at its gross value.
A reconciliation of activity to the liability during the quarter ended April 30, 2007 is as follows:

The remaining balance of $53,000 consists of voluntary severance of $36,000 that will be amortized through August 2007 and $17,000 for outplacement services that will either be used or expire by June 2007.
10. Share-Based Payments.
At our annual meeting of shareholders, held March 3, 2006, shareholders approved the Piedmont Natural Gas Company, Inc. Incentive Compensation Plan (ICP) effective November 1, 2005. The ICP permits the grant of annual incentive awards, performance awards, restricted stock, stock options and stock appreciation rights to eligible employees and members of the Board of Directors.
Under our ICP, 65,000 restricted shares of our common stock with a value at the date of grant of $1.7 million were granted to our Chairman, President and Chief Executive Officer on September 1, 2006. During the vesting period, any dividends paid on these shares will be accrued and converted into additional shares at the closing price on the date of the dividend payment. The restricted shares and any additional shares accrued through dividends will vest over a three-year period to five-year period only if he is an employee on each vesting date. For the three months and six months ended April 30, 2007, we have recorded compensation expense under this grant of $.1 million and $.2 million, respectively. We are recording compensation under the ICP on the straight-line method.
Under the Executive Long-Term Incentive Plan (LTIP) and ICP, the Board of Directors has awarded units to eligible officers and other participants. Depending upon the levels of performance targets achieved by Piedmont during multi-year performance periods, distribution of those awards may be made in the form of shares of common stock and cash withheld for payment of applicable taxes on the compensation. The LTIP and ICP require that a minimum threshold performance be achieved in order for any award to be distributed. For the three months and six months ended April 30, 2007, we recorded compensation expense for the LTIP and ICP of $1.1 million and $2.2 million, respectively, including compensation on the restricted share award above. Shares of common stock to be issued under the LTIP and ICP are contingently issuable shares and are included in our calculation of fully diluted earnings per share.
As of April 30, 2007 and October 31, 2006, we have accrued $7 million and $11.4 million for these awards. The accrual is based on the fair market value of our stock at the end each quarter. The liability is re-measured to market value at the settlement date.
11. Commitments and Contingent Liabilities.
          Long-term contracts
We routinely enter into long-term commodity and capacity commitments and agreements that commit future cash flows to acquire services we need in our business. These commitments include pipeline and storage capacity contracts and gas supply contracts to provide service to our customers and telecommunication and information technology contracts and other purchase obligations. The time periods for pipeline and storage capacity contracts range from one to seventeen years. The time periods for gas supply contracts range from one to three years. The time periods for the telecommunications and technology contracts providing

maintenance fees for hardware and software applications, usage fees, local and long-distance data costs, frame relay, cell phone and pager usage fees range from one to five years. Other purchase obligations consist primarily of commitments for pipeline products, vehicles and contractors.
Certain storage and pipeline capacity contracts require the payment of a demand charge that is based on rates established by the FERC in order to maintain the ability to access the natural gas storage or the pipeline capacity on a firm basis during the contract term period. The demand charges that are incurred in each period are recognized in the consolidated statement of income as part of gas purchases and included in cost of gas.
          Leases
We lease certain buildings, land and equipment for use in our operations under noncancelable operating leases.
          Legal
We have only routine litigation in the normal course of business.
          Environmental Matters
Our three state regulatory commissions have authorized us to utilize deferral accounting in connection with environmental costs. Accordingly, we have established regulatory assets for actual environmental costs incurred and for estimated environmental liabilities recorded. We have owned, leased or operated thirteen manufactured gas plant (MGP) sites. We entered into a settlement with a third party with respect to nine MGP sites that we have owned, leased or operated and paid an amount, charged to the estimated environmental liability, that released us from any investigation and remediation liability. Although no such claims are pending or, to our knowledge, threatened, the settlement did not cover any third-party claims for personal injury, death, property damage and diminution of property value or natural resources. We also have liability for any third-party claims for personal injury, death, property damage and diminution of property value or natural resources related to a MGP site connected with our acquisition of North Carolina Natural Gas Corporation.
Of the 13 MGP sites, we have accrued an estimated liability for the remaining four sites. In May 2007, we received a letter from the North Carolina Department of Environment and Natural Resources requesting initiation of a remedial investigation of our Hickory, North Carolina MGP site and submission by August 3, 2007 of a work plan for review. The limited site assessment report prepared in 1994 concluded that gas plant residuals remaining on the Hickory site are thought to be mostly contained within two former tar separators associated with our site’s operations. Further evaluation of the Hickory MGP site or other MGP sites could significantly affect recorded amounts; however, we believe that the ultimate resolution of these matters will not have a material adverse effect on our financial position, cash flows or results of operations.
          Letters of Credit
We use letters of credit to guarantee claims from self-insurance under our general liability policies.
Additional information concerning commitments and contingencies is set forth in Note 7 and “Financial Condition and Liquidity” in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of our Form 10-K for the year ended October 31, 2006.

Forward-Looking Statements
This report as well as other documents we file with the SEC may contain forward-looking statements. In addition, our senior management and other authorized spokespersons may make forward-looking statements in print or orally to analysts, investors, the media and others. These statements are based on management’s current expectations and information currently available, and are believed to be reasonable and are made in good faith. However, the forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those projected in the statements. Factors that may make the actual results differ from anticipated results include, but are not limited to:
    Regulatory issues, including those that affect allowed rates of return, terms and conditions of service, rate structures and financings. We monitor our effectiveness in achieving the allowed rates of return and initiate rate proceedings or operating changes as needed. In addition, we purchase natural gas transportation and storage services from interstate and intrastate pipeline companies whose rates and services are regulated.
 
    Residential, commercial and industrial growth in our service areas. The ability to grow our customer base and the pace of that growth are impacted by general business and economic conditions, such as interest rates, inflation, fluctuations in the capital markets and the overall strength of the economy in our service areas and the country, and fluctuations in the wholesale prices of natural gas and competitive energy sources.
 
    Deregulation, regulatory restructuring and competition in the energy industry. We face competition from electric companies and energy marketing and trading companies, and we expect this competitive environment to continue. We must be able to adapt to the changing environments and the competition.
 
    The potential loss of large-volume industrial customers to alternate fuels or to bypass, or the shift by such customers to special competitive contracts at lower per-unit margins.
 
    Regulatory issues, customer growth, deregulation, economic and capital market conditions, the cost and availability of natural gas and weather conditions can impact our ability to meet internal performance goals.
 
    The capital-intensive nature of our business. In order to maintain growth, we must add to our natural gas distribution system each year. The cost of this construction may be affected by the cost of obtaining governmental approvals, compliance with federal and state pipeline safety and integrity regulations, development project delays and changes in project costs. Weather, general economic conditions and the cost of funds to finance our capital projects can materially alter the cost of a project.
 
    Capital market conditions. Our internally generated cash flows are not adequate to finance the full cost of capital expenditures. As a result, we rely on access to both short-term and long-term capital markets as a significant source of liquidity for capital requirements not satisfied by cash flows from operations. Changes in the capital markets could affect access to and cost of capital.
 
    Changes in the availability and cost of natural gas. To meet firm customer requirements, we must acquire sufficient gas supplies and pipeline capacity to ensure delivery to our distribution system while also ensuring that our supply and capacity contracts allow us to remain competitive. Natural gas is an unregulated commodity market subject to supply and demand and price volatility. Producers, marketers and pipelines are subject to operating and financial risks associated with exploring, drilling, producing, gathering, marketing and transporting natural gas and have risks that increase our exposure to supply and price fluctuations.

    Changes in weather conditions. Weather conditions and other natural phenomena can have a material impact on our earnings. Severe weather conditions, including destructive weather patterns such as hurricanes, can impact our suppliers and the pipelines that deliver gas to our distribution system. Weather conditions directly influence the supply of, demand for and the cost of natural gas.
 
    Changes in environmental, safety and system integrity regulations and the cost of compliance. We are subject to extensive federal, state and local regulations. Compliance with such regulations may result in increased capital or operating costs.
 
    Ability to retain and attract professional and technical employees. To provide quality service to our customers and meet regulatory requirements, we are dependent on our ability to recruit, train, motivate and retain qualified employees.
 
    Changes in accounting regulations and practices. We are subject to accounting regulations and practices issued periodically by accounting standard-setting bodies. New accounting standards may be issued that could change the way we record revenues, expenses, assets and liabilities. Future changes in accounting standards could affect our reported earnings or increase our liabilities.
 
    Earnings from our equity method investments. We invest in companies that have risks that are inherent in their businesses, and we assume such risks as an equity investor.
Other factors may be described elsewhere in this report. All of these factors are difficult to predict and many of them are beyond our control. For these reasons, you should not rely on these forward-looking statements when making investment decisions. When used in our documents or oral presentations, the words “expect,” “believe,” “project,” “anticipate,” “intend,” “should,” “could,” “will,” “assume,” “can,” “estimate,” “forecast,” “future,” “indicate,” “outlook,” “plan,” “predict,” “seek,” “target,” “would” and variations of such words and similar expressions are intended to identify forward-looking statements.

Overview
Piedmont Natural Gas Company is an energy services company primarily engaged in the distribution of natural gas to residential, commercial and industrial customers in portions of North Carolina, South Carolina and Tennessee. We also have equity method investments in joint venture, energy-related businesses. Our operations are comprised of two business segments — the regulated utility segment and the non-utility activities segment.
The regulated utility segment is the largest segment of our business with approximately 97% of our consolidated assets. This segment is regulated by three state regulatory commissions that approve rates and tariffs that are designed to give us the opportunity to generate revenues to cover our gas and non-gas costs and to earn a fair rate of return for our shareholders. Factors critical to the success of the regulated utility include a safe, reliable natural gas distribution system and the ability to recover the costs and expenses of the business in rates charged to customers. For the six months ended April 30, 2007, 86% of our earnings before taxes

came from our regulated utility segment.
The non-utility activities segment consists of our equity method investments in joint venture, energy-related businesses that are involved in unregulated retail natural gas marketing, interstate natural gas storage and intrastate natural gas transportation. We invest in joint ventures that are aligned with our business strategies to complement or supplement income from utility operations. We continually monitor performance of these ventures against expectations.
Weather conditions directly influence the volumes of natural gas delivered by the regulated utility. Significant portions of our revenues are generated during the winter season. During warm winters or unevenly cold winters, heating customers may significantly reduce their consumption of natural gas. In South Carolina and Tennessee, we have weather normalization adjustment (WNA) mechanisms that are designed to protect a portion of our revenues against warmer-than-normal weather as deviations from normal weather can affect our financial performance and liquidity. The WNA also serves to offset the impact of colder-than-normal weather by reducing the amounts we can charge our customers. In North Carolina, a Customer Utilization Tracker (CUT) provides for the recovery of our approved margin per customer independent of both weather and other consumption patterns of residential and commercial customers. For further information, see “Our Business” in Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Over the past few years, there have been significant increases in the wholesale cost of natural gas. The relationship between supply and demand has the greatest impact on wholesale gas prices. Increased wholesale prices for natural gas are being driven by increased demand that is exceeding the growth in accessible supply. Continued high gas prices could shift our customers’ preference away from natural gas toward other energy sources, particularly in the industrial market. High gas prices could also affect consumption levels as customers react to high bills. We expect that the wholesale price of natural gas will remain high and volatile until natural gas supply and demand are in better balance.
The majority of our natural gas supplies come from the Gulf Coast region. We believe that diversification of our supply portfolio is in our customers’ best interest. We have a firm transportation contract pending with Midwestern Gas Transmission Company for additional pipeline capacity that will provide access to Canadian and Rocky Mountain gas supplies via the Chicago hub, primarily to serve our Tennessee markets. Due to regulatory delays impacting the commencement of construction for service, Midwestern only provided a portion of the original contracted capacity during the winter of 2006-2007. It is anticipated that the entire capacity will be available during the 2007-2008 winter. We have also executed an agreement with Hardy Storage Company, LLC for market-area storage capacity in West Virginia that began its initial phase service in April 2007.
Part of our strategic plan is to manage our gas distribution business through control of our operating costs, implementation of new technologies and sound rate and regulatory initiatives. We are working to enhance the value and growth of our utility assets by good management of capital spending, including improvements for current customers and the pursuit of customer growth opportunities in our service areas. We strive for quality customer service by investing in technology, processes and people. We work with our state regulators to maintain fair rates of return and balance the interests of our customers and shareholders.
Our strategic plan includes a focus on maintaining a long-term debt-to-capitalization ratio within a range of 45% to 50%. We will continue to stress the importance of maintaining a strong balance sheet and investment-grade credit ratings to support our operating and investment needs.

Operating Revenues
Operating revenues increased $48.4 million for the three months ended April 30, 2007, compared with the similar period in 2006 due to the following increases:
    $51.9 million from increased volumes delivered to sales customers related to commodity costs.
 
    $30.7 million from increased volumes delivered to sales customers related to non-commodity components in rates.
 
    $4.1 million from increased volumes delivered to transportation customers.
These increases were partially offset by the following decreases:
    $18.4 million decrease from lower commodity gas costs passed through to sales customers.

22


Table of Contents

    $12.6 million lower revenues under the CUT mechanism in 2007 compared to 2006. As discussed in “Financial Condition and Liquidity” below, the CUT mechanism became effective November 1, 2005 in North Carolina to offset the impact of conservation and colder-than-normal or warmer-than-normal weather on residential and commercial customer margin.
 
    $3.5 million decrease related to non-commodity components in rates.
 
    $1.6 million lower revenues under the WNA in 2007 as compared to 2006. As discussed in “Financial Condition and Liquidity” below, we have a WNA in South Carolina and Tennessee to offset the impact of colder-than-normal or warmer-than-normal weather on residential and commercial customer margin.
Operating revenues decreased $195.7 million for the six months ended April 30, 2007, compared with the similar period in 2006 due to the following decreases:
    $196.6 million from lower commodity gas costs passed through to sales customers.
 
    $46.5 million lower revenues from secondary market transactions in 2007 compared to 2006. Secondary market transactions consist of off-system sales and capacity release arrangements.
 
    $6.3 million lower revenues under the CUT mechanism in 2007 compared to 2006..
Theses decreases were partially offset by the following increases:
    $22 million increase from increased volumes to sales customers related to non-commodity components in rates.
 
    $13.5 million from increased volumes delivered to sales customers related to commodity costs.
 
    $7.3 million from increased volumes delivered to transportation customers.
 
    $5 milllion increase related to non-commodity components in rates.
 
    $1.3 million increased revenues under the WNA in 2007 as compared to 2006.
Cost of Gas
Cost of gas increased $42.7 million for the three months ended April 30, 2007, compared with the similar period in 2006 primarily due to an increase of $51.9 million from increased volumes delivered to sales customers. This increase was partially offset by a decrease of $18.4 million from lower commodity gas costs passed through to sales customers.
Cost of gas decreased $200.6 million for the six months ended April 30, 2007, compared with the similar period in 2006 primarily due to the following decreases:
    $196.6 million from lower commodity gas costs passed through to sales customers.
 
    $47.3 million from lower secondary market activity.
These decreases were offset by an increase of $13.5 million from increased volumes delivered to sales customers.
Under purchased gas adjustments (PGA) procedures in all three states, we revise rates periodically without formal rate proceedings to reflect changes in the wholesale cost of natural gas. Charges to cost of gas are based on the amount recoverable under approved rate schedules. The net of any over- or under-recoveries of gas costs are added to or deducted from cost of gas and included in “Amounts due from customers” or “Amounts due to customers” in the condensed consolidated balance sheets.

Margin
Margin increased $5.7 million for the three months ended April 30, 2007, and $4.8 million for the six months ended April 30, 2007, compared with the similar periods in 2006 primarily due to the growth in our residential, commercial and power generation customer base. The increase in the six-month period was partially offset by $1.5 million of gas cost accounting adjustments related to lost and unaccounted for gas and interest charges related to natural gas purchases and $.75 million due to the timing of annual adjustments under the CUT settlement.
Our utility margin is defined as natural gas revenues less natural gas commodity purchases and fixed gas costs for upstream capacity. Margin, rather than revenues, is used by management to evaluate utility operations due to the impact of volatile wholesale commodity prices, which account for approximately 70% of revenues.
Our utility margin is impacted also by certain regulatory mechanisms as defined elsewhere in this document or in our Form 10-K for the year ended October 31, 2006. These include WNA in Tennessee and South Carolina, the Natural Gas Rate Stabilization in South Carolina, TIP in Tennessee, CUT in North Carolina, negotiated loss treatment in all three jurisdictions and the collection of uncollectible gas costs in all three jurisdictions.
We retain 25% of margins generated through off-system sales and capacity release activity related to North Carolina and South Carolina, with 75% credited to customers through the PGA mechanism.
Operations and Maintenance Expenses
Operations and maintenance expenses decreased $4.8 million for the three months ended April 30, 2007, compared with the similar period in 2006 primarily due to the following decreases:
    $5.5 million in payroll primarily related to the 2006 management restructuring program, including impacts on short-term and long-term incentive plan accruals.
 
    $.6 million in outside services primarily due to less third party expenditures related to the customer service activities.
 
    $.5 million in transportation costs primarily due to fewer vehicles being used as a result of the automated meter reading initiative.
 
    $.4 million in other corporate expense primarily due to the timing of the funding of conservation programs in accordance with NCUC orders regarding the CUT.
These decreases were partially offset by the following increases:
    $1 million in the provision for uncollectibles primarily due to an adjustment to the allowance for amounts related to trade receivables.
 
    $.8 million in employee benefits primarily due to adjustments in group insurance expense.
Operations and maintenance expenses decreased $5.9 million for the six months ended April 30, 2007, compared with the similar period in 2006 primarily due to the following decreases:
    $7 million in payroll primarily related to the 2006 management restructuring program, including impacts on short-term and long-term incentive plan accruals.
 
    $.7 million in transportation costs primarily due to fewer vehicles being used as a result of the automated meter reading initiative.

Table of Contents

These decreases were partially offset by the following increases:
    $1 million in employee benefits primarily due to adjustments in group insurance expense.
 
    $.6 million in outside services primarily due to increased telephony services.
 
    $.3 million in the provision for uncollectibles primarily due to an adjustment to the allowance for amounts related to trade receivables, partially offset by amounts related to changes in the recovery of the gas cost component of uncollectibles under regulatory mechanisms in 2007.
Depreciation
Depreciation expense for the three months and six months ended April 30, 2007 was comparable with the similar prior periods.
General Taxes
General taxes increased $.3 million for the three months ended April 30, 2007, and $.9 million for the six months ended April 30, 2007, as compared with the similar periods in 2006 primarily due to increases in gross receipts taxes, property taxes and state franchise taxes, partially offset by a decrease in payroll taxes.
Other Income (Expense)
Income from equity method investments includes our earnings from joint venture investments. Income from equity method investments increased $3.4 million and $3.2 million for the three months and six months ended April 30, 2007, respectively, compared with the similar periods in 2006. These increases were primarily due to increased earnings from SouthStar of $2.9 million and from Hardy Storage of $.8 million for the three months ended April 30, 2007, and increased earnings from SouthStar of $2.9 million and from Hardy Storage of $.6 million for the six months ended April 30, 2007. Non-operating income is comprised of non-regulated merchandising and service work, subsidiary operations, interest income and other miscellaneous income. Non-operating expense is comprised of charitable contributions and other miscellaneous expenses. The changes in non-operating income and non-operating expense are not significant.
Utility Interest Charges
Utility interest charges increased $.9 million for the three months ended April 30, 2007, compared with the similar period in 2006 primarily due to the following increases:
    $2.3 million in interest on long-term debt due to the issuance on June 20, 2006 of $200 million of insured quarterly notes due June 1, 2036.
 
    $.4 million in interest expense on regulatory treatment of certain components of deferred income taxes.
These increases were partially offset by the following decreases:
    $1.5 million in interest on short-term debt due to lower balances outstanding in 2007.
 
    $.3 million due to an increase in the allowance for funds used during construction allocated to debt.
Utility interest charges increased $2.6 million for the six months ended April 30, 2007, compared with the similar period in 2006 primarily due to the following increases:

    $4.6 million in interest on long-term debt due to the issuance on June 20, 2006 of $200 million of insured quarterly notes due June 1, 2036.
 
    $.7 million in interest expense on regulatory treatment of certain components of deferred income taxes.
These increases were partially offset by the following decreases:

Our Business
Piedmont Natural Gas Company, Inc., which began operations in 1951, is an energy services company primarily engaged in the distribution of natural gas to 1,016,000 residential, commercial and industrial customers in portions of North Carolina, South Carolina and Tennessee, including 62,000 customers served by municipalities who are our wholesale customers. We are invested in joint venture, energy-related businesses, including unregulated retail natural gas marketing, interstate natural gas storage and intrastate natural gas transportation.
We continually assess the nature of our business and explore alternatives to traditional utility regulation. Non-traditional ratemaking initiatives and market-based pricing of products and services provide additional challenges and opportunities for us. We also regularly evaluate opportunities for obtaining natural gas supplies from different production regions and supply sources to maximize our natural gas portfolio flexibility and reliability, including the diversification of our supply portfolio through pipeline capacity arrangements that access new sources of supply and market-area storage and that diversify supply concentration away from the Gulf Coast region. We have a firm transportation contract pending with Midwestern Gas Transmission Company for 120,000 dekatherms per day of additional pipeline capacity that will provide access to Canadian and Rocky Mountain gas supplies via the Chicago hub, primarily to serve our Tennessee markets. Due to regulatory delays impacting the commencement of construction for service, Midwestern only provided a portion of the original contracted quantity during the winter of 2006-2007. It is anticipated that the entire capacity will be available during the 2007-2008 winter. We have also executed an agreement with Hardy Storage Company, LLC for market-area storage capacity in West Virginia that began its initial service in April 2007.
We have two reportable business segments, regulated utility and non-utility activities. For further information on business segments, see Note 6 to the condensed consolidated financial statements.
Our utility operations are regulated by the NCUC, Public Service Commission of South Carolina and the TRA as to rates, service area, adequacy of service, safety standards, extensions and abandonment of facilities, accounting and depreciation. We are also regulated by the NCUC as to the issuance of securities. We are also subject to or affected by various federal regulations. These federal regulations include regulations that are particular to the natural gas industry, such as regulations of the FERC that affect the availability of and the prices paid for the interstate transportation and storage of natural gas, regulations of the Department of Transportation that affect the construction, operation, maintenance, integrity and safety of natural gas distribution and transmission systems, and regulations of the Environmental Protection Agency relating to the use and release into the environment of hazardous wastes. In addition, we are subject to numerous regulations, such as those relating to employment practices, which are generally applicable to companies doing business in the United States of America.

In the Carolinas, our service area is comprised of numerous cities, towns and communities. We maintain service offices in Anderson, Gaffney, Greenville and Spartanburg in South Carolina and Charlotte, Salisbury, Greensboro, Winston-Salem, High Point, Burlington, Hickory, Indian Trail, Spruce Pine, Reidsville, Fayetteville, New Bern, Wilmington, Tarboro, Elizabeth City, Rockingham and Goldsboro in North Carolina. In North Carolina, we also provide wholesale natural gas service to Greenville, Monroe, Rocky Mount and Wilson. In Tennessee, our service area is the metropolitan area of Nashville, including wholesale natural gas service to Gallatin and Smyrna.
Our regulatory commissions approve rates and tariffs that are designed to give us the opportunity to generate revenues to cover our gas and non-gas costs and to earn a fair rate of return for our shareholders. In North Carolina, the CUT provides for the recovery of our approved margin per customer independent of both weather or other consumption patterns of residential and commercial customers. The CUT tracks our margin earned monthly and will result in semi-annual rate adjustments to refund any over-collection or recover any under-collection. We have a WNA mechanism in South Carolina and Tennessee that partially offsets the impact of colder-than-normal or warmer-than-normal weather on bills rendered during the months of November through March for residential and commercial customers. The WNA formula calculates the actual weather variance from normal, using 30 years of history, which results in an increase in revenues when weather is warmer than normal and a decrease in revenues when weather is colder than normal. The gas cost portion of our costs is recoverable through PGA procedures and is not affected by the WNA.
We invest in joint ventures to complement or supplement income from our regulated utility operations. If an opportunity aligns with our overall business strategies, we analyze and evaluate the project with a major factor being a projected rate of return greater than the returns allowed in our utility operations, due to the higher risk of such projects. We participate in the governance of the venture by having management representation on the governing board of the venture. We monitor actual performance against expectations. Decisions regarding exiting joint ventures are based on many factors, including performance results and continued alignment with our business strategies.
Financial Condition and Liquidity
To meet our capital and liquidity requirements, we rely on certain resources, including cash flows from operating activities, access to capital markets, cash generated from our investments in joint ventures and short-term bank borrowings. We believe that these sources will continue to allow us to meet our needs for working capital, construction expenditures, anticipated debt redemptions and dividend payments.
Cash Flows from Operating Activities . The natural gas business is seasonal in nature. Operating cash flows may fluctuate significantly during the year and from year to year due to working capital changes within our utility and non-utility operations resulting from such factors as weather, natural gas purchases and prices, natural gas storage activity, collections from customers and deferred gas cost recoveries. We rely on operating cash flows and short-term bank borrowings to meet seasonal working capital needs. During our first and second quarters, we generally experience overall positive cash flows from the sale of flowing gas and gas in storage and the collection of amounts billed to customers during the peak heating season (November through March). Cash requirements generally increase during the third and fourth quarters due to increases in natural gas purchases for storage, paying down short-term debt and decreases in receipts from customers.
During the peak heating season, our accounts payable increase to reflect amounts due to our natural gas suppliers for commodity and pipeline capacity. The cost of the natural gas can vary significantly from period to period due to volatility in the price of natural gas, which is a function of market fluctuations in the price of natural gas, along with our changing requirements for storage volumes. Our natural gas costs and amounts due

27


Table of Contents

to/from customers represent the difference between natural gas costs that we have paid to suppliers and amounts that we have collected from customers. These natural gas costs can cause cash flows to vary significantly from period to period along with variations in the timing of collections from customers under our gas cost recovery mechanisms.
Cash flows from operations are impacted by weather, which affects natural gas purchases and sales. Warmer weather can lead to lower revenues from fewer volumes of natural gas sold or transported. Colder weather can increase volumes sold to weather-sensitive customers, but may lead to conservation by customers in order to reduce their heating bills. Temperatures above normal can lead to reduced operating cash flows, thereby increasing the need for short-term borrowings to meet current cash requirements.
Net cash provided by operating activities was $283.7 million and $71.2 million for the six months ended April 30, 2007 and 2006, respectively. Net cash provided by operating activities reflects a $6.1 million increase in net income for 2007, compared with 2006, along with changes in working capital as described below:
    Trade accounts receivable and unbilled utility revenues decreased cash flow $57.1 million in the current period and $57.3 million in the prior period. Trade accounts receivable increased by $63.5 million from our fiscal year end due to an increase in volumes delivered of 8.1 million dekatherms.
 
    Trade accounts payable increased cash flow by $23.6 million in the current period compared with a decrease in cash flow of $104 million in the prior period. Trade accounts payable, including accounts payable for construction work in progress, increased by $21.3 million from our fiscal year end primarily due to an increase in the amount of gas purchase payables.
 
    Amounts due to/from customers increased cash flow by $47.8 million in the current period compared with a decrease in cash flow of $31.8 million in the prior period. Amounts due to/from customers decreased $47.8 million from our fiscal year end due to the recovery of gas costs deferred in the prior period.
 
    Refundable income taxes increased cash flow by $30.8 million in the current period as compared with $8.3 million increase to cash flow in the prior period due to the application of refundable income taxes to later periods.
 
    Income taxes accrued increased cash flow by $11.1 million in the current period compared with a decrease in cash flow of $6.1 million in the prior period due to changes in the components of taxable income.
 
    Gas in storage increased cash flow by $32.5 million in the current period as compared with an increase in cash flow of $44 million in the prior period primarily due to sales of volumes withdrawn from storage for delivery in the winter heating season.
 
    Gas purchase options, at fair value, decreased cash flow by $5.7 million in the current period compared with an increase in cash flow of $21.4 million in the prior period due to decreases in the market values of financial derivatives.
Our regulatory commissions approve rates that are designed to give us the opportunity to generate revenues, assuming normal weather, to cover our gas costs and fixed and variable non-gas costs and to earn a fair return for our shareholders. We have had a WNA mechanism in South Carolina and Tennessee that partially offsets the impact of colder-than-normal or warmer-than-normal weather on bills rendered in November through March for residential and commercial customers. The WNA in South Carolina and Tennessee generated charges to customers of $5.8 million in the six months ended April 30, 2007 and charges to customers of $4.5 million in the six months ended April 30, 2006. In Tennessee, adjustments are made directly to the customer’s bills. In South Carolina, the adjustments are calculated at the individual customer level and recorded in a deferred account for subsequent collection from or refund to all customers in the class. The

CUT mechanism in North Carolina provides for any over- or under-collection of approved margin per customer that operates independently of both weather and consumption patterns of residential and commercial customers. The CUT mechanism provided margin of $22.9 million and $29.3 million in the six months ended April 30, 2007 and 2006, respectively. Our gas costs are recoverable through PGA procedures and are not affected by the WNA or the CUT.
The financial condition of the natural gas marketers and pipelines that supply and deliver natural gas to our distribution system can increase our exposure to supply and price fluctuations. We believe our risk exposure to the financial condition of the marketers and pipelines is not significant based on our receipt of the products and services prior to payment and the availability of other marketers of natural gas to meet our firm supply needs if necessary.
We have commission approval in North Carolina, South Carolina and Tennessee that places additional credit requirements on the retail natural gas marketers that schedule gas for transportation service on our system.
The regulated utility competes with other energy products, such as electricity and propane, in the residential and commercial customer markets. The most significant product competition is with electricity for space heating, water heating and cooking. Numerous factors can influence customer demand for natural gas, such as price volatility, the availability of natural gas in relation to other energy forms, general economic conditions, weather, energy conservation, conservation and energy efficiency programs approved by regulatory bodies and the ability to convert from natural gas to other energy sources. Increases in the price of natural gas can negatively impact our competitive position by decreasing the price benefits of natural gas to the consumer. This can impact our cash needs if customer growth slows, resulting in reduced capital expenditures, or if customers conserve, resulting in reduced gas purchases and customer billings.
In the industrial market, many of our customers are capable of burning a fuel other than natural gas, with fuel oil being the most significant competing energy alternative. Our ability to maintain industrial market share is largely dependent on price. The relationship between supply and demand has the greatest impact on the price of natural gas. With a tighter balance between domestic supply and demand, the cost of natural gas from non-domestic sources may play a greater role in establishing the future market price of natural gas. The price of oil depends upon a number of factors beyond our control, including the relationship between supply and demand and the policies of foreign and domestic governments and organizations. Our liquidity could be impacted, either positively or negatively, as a result of alternate fuel decisions made by industrial customers.
Cash Flows from Investing Activities . Net cash used in investing activities was $59.4 million and $78.6 million for the six months ended April 30, 2007 and 2006, respectively. Net cash used in investing activities was primarily for utility construction expenditures. Gross utility construction expenditures for the six months ended April 30, 2007, were $60.6 million as compared to $100.8 million in the similar prior period. The decrease was primarily due to several large projects in 2006, such as automated meter reading, certain revenue-producing projects in our service area and enterprise telephony that are now complete or nearing completion. Reimbursements from the bond fund decreased $13.1 million from 2006 as construction of gas infrastructure in eastern North Carolina is complete.
During the six months ended April 30, 2006, the restrictions on cash totaling $13.1 million were removed in connection with implementing the NCUC order in our last general rate proceeding. The cash was previously held in an expansion fund to extend natural gas service to unserved areas of the state.
We have a substantial capital expansion program for construction of distribution facilities, purchase of equipment and other general improvements. This program primarily supports the growth in our customer base. Gross utility construction expenditures totaling $144.8 million, primarily to serve customer growth, are

Table of Contents

budgeted for fiscal year 2007; however, we are not contractually obligated to expend capital until work is completed. Due to projected growth in our service areas, significant utility construction expenditures are expected to continue and are a part of our long-range forecasts that are prepared at least annually and typically cover a forecast period of five years.
Cash Flows from Financing Activities . Net cash provided by (used in) financing activities was $(222.8) million and $20.7 million for the six months ended April 30, 2007 and 2006, respectively. Funds are primarily used in paying down outstanding short-term borrowings, the repurchase of common stock under the common stock repurchase program, net of the issuance of common stock through dividend reinvestment and employee stock plans, and the payment of quarterly dividends on our common stock. Funds are primarily provided from bank borrowings and the issuance of common stock through dividend reinvestment and employee stock plans, net of purchases under the common stock repurchase program. We sell common stock and long-term debt to cover cash requirements when market and other conditions favor such long-term financing. As of April 30, 2007, our current assets were $385.4 million and our current liabilities were $265.1 million, primarily due to seasonal requirements as discussed above.
As of April 30, 2007, we had committed lines of credit under our senior credit facility effective April 24, 2006, of $350 million with the ability to expand up to $600 million, for which we pay an annual fee of $35,000 plus six basis points for any unused amount up to $350 million. Outstanding short-term borrowings decreased from $170 million as of October 31, 2006, to $29.5 million as of April 30, 2007, primarily due to collections from customers and reductions in working capital needs. During the six months ended April 30, 2007, short-term borrowings ranged from zero to $280.5 million, and when we borrowed under the facility, interest rates ranged from 5.57% to 5.6% (weighted average of 5.58%).
As of April 30, 2007, we had available letters of credit under our credit facility of $5 million of which $1.5 million was issued and outstanding. The letters of credit are used to guarantee claims from self-insurance under our general liability policies. As of April 30, 2007, unused lines of credit available under our senior credit facility, including the issuance of the letters of credit, totaled $319 million.
The level of short-term borrowings can vary significantly due to changes in the wholesale prices of natural gas and to the level of purchases of natural gas supplies to serve customer demand and for storage. Short-term debt may increase when wholesale prices for natural gas increase because we must pay suppliers for the gas before we collect our costs from customers through their monthly bills. Gas prices could continue to increase and fluctuate. If wholesale gas prices remain high, we may incur more short-term debt to pay for natural gas supplies and other operating costs since collections from customers could be slower and some customers may not be able to pay their gas bills on a timely basis.
During the six months ended April 30, 2007, we issued $8.1 million of common stock through dividend reinvestment and stock purchase plans. On November 7, 2006, through an ASR agreement, we repurchased and retired 1 million shares of common stock for $26.6 million. On January 19, 2007, we settled the transaction and paid an additional $.8 million. On April 2, 2007, through an ASR agreement, we repurchased and retired 850,000 shares of common stock for $22.5 million. Under the Common Stock Open Market Purchase Program, as described in Part II, Item 2, we paid $53.8 million during the six months ended April 30, 2007 for 2 million shares of common stock that are available for reissuance under these plans.
Through the ASR program, we may repurchase and subsequently retire up to approximately four million shares of common stock by no later than December 31, 2010, including the one million shares repurchased in April 2006, the one million shares repurchased in November 2006 and the 850,000 shares repurchased in March 2007. These shares are in addition to shares that are repurchased on a normal basis through the open

market program.
We have paid quarterly dividends on our common stock since 1956. The amount of cash dividends that may be paid is restricted by provisions contained in certain note agreements under which long-term debt was issued. As of April 30, 2007, our retained earnings were not restricted. On June 6, 2007, the Board of Directors declared a quarterly dividend on common stock of $.25 per share, payable July 13, 2007 to shareholders of record at the close of business on June 22, 2007.
Our long-term targeted capitalization ratio is 45% to 50% in long-term debt and 50% to 55% in common equity. Accomplishing this capital structure objective and maintaining sufficient cash flow are necessary to maintain attractive credit ratings. As of April 30, 2007, our long-term capitalization consisted of 47% in long-term debt and 53% in common equity.
The components of our total debt outstanding to our total capitalization as of April 30, 2007 and 2006, and October 31, 2006, are summarized in the table below.

Credit ratings impact our ability to obtain short-term and long-term financing and the cost of such financings. In determining our credit ratings, the rating agencies consider a number of quantitative factors, including debt to total capitalization, operating cash flows relative to outstanding debt, operating cash flow coverage of interest and pension liabilities and funding status. Rating agencies also consider qualitative factors, such as the consistency of our earnings over time, the quality of management and business strategy, the risks associated with our utility and non-utility businesses and the regulatory commissions that establish rates in the states where we operate.
As of April 30, 2007, all of our long-term debt was unsecured. Our long-term debt is rated “A” by Standard & Poor’s Ratings Services and “A3” by Moody’s Investors. Currently, with respect to our long-term debt, the credit agencies maintain their stable outlook. There is no guarantee that a rating will remain in effect for any given period of time or that a rating will not be lowered or withdrawn by a rating agency if, in its judgment, circumstances warrant a change.
We are subject to default provisions related to our long-term debt and short-term borrowings. Failure to satisfy any of the default provisions would result in total outstanding issues of debt becoming due. There are cross-default provisions in all our debt agreements. As of April 30, 2007, we are in compliance with all default provisions.
Estimated Future Contractual Obligations
During the three months ended April 30, 2007, there were no material changes to our estimated future contractual obligations that were disclosed in our Form 10-K for the year ended October 31, 2006, in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” other than a commitment to fund 30% of the construction financing of the Hardy Storage project with equity

contributions, of which our equity portion was $12.9 million as of April 30, 2007. For further information on this commitment, see Note 7 to the condensed consolidated financial statements.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements other than operating leases that were discussed in Note 7 to the consolidated financial statements in our Form 10-K for the year ended October 31, 2006 and the guaranty disclosed below.
Piedmont Energy Partners, Inc., a wholly-owned subsidiary of Piedmont, has entered into a guaranty in the normal course of business. The guaranty involves levels of performance and credit risk that are not included on our condensed consolidated balance sheets. The possibility of having to perform on the guaranty is largely dependent upon the future operations of the joint venture, third parties or the occurrence of certain future events. For further information on this guaranty, see Note 7 to the condensed consolidated financial statements.
Critical Accounting Policies and Estimates
We prepare the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. We make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods reported. Actual results may differ significantly from these estimates and assumptions. We base our estimates on historical experience, where applicable, and other relevant factors that we believe are reasonable under the circumstances. On an ongoing basis, we evaluate estimates and assumptions and make adjustments in subsequent periods to reflect more current information if we determine that modifications in assumptions and estimates are warranted.
Management considers an accounting estimate to be critical if it requires assumptions to be made that were uncertain at the time the estimate was made and changes in the estimate or a different estimate that could have been used would have had a material impact on our financial condition or results of operations. We consider regulatory accounting, revenue recognition, goodwill and pension and postretirement benefits to be our critical accounting estimates. Management is responsible for the selection of the critical accounting estimates presented in our Form 10-K for the year ended October 31, 2006, in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Management has discussed these critical accounting estimates with the Audit Committee of the Board of Directors. There have been no changes in our critical accounting policies and estimates since October 31, 2006.
Recent Accounting Pronouncements
In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, “Accounting for Uncertainty in Income Taxes” (FIN 48), to clarify the accounting for uncertain tax positions in accordance with SFAS 109, “Accounting for Income Taxes.” FIN 48 defines a minimum recognition threshold that a tax position must meet to be recognized in an enterprise’s financial statements. Additionally, FIN 48 provides guidance on derecognition, measurement, classification, interim period accounting, disclosure and transition requirements in accounting for uncertain tax positions. This interpretation is effective the beginning of the first annual period beginning after December 15, 2006. On May 2, 2007, the FASB issued Staff Position (FSP) No. FIN 48-1, “Definition of Settlement in FIN 48,” to clarify when a tax position is considered settled under FIN 48. The guidance in FSP No. FIN 48-1 should be applied upon adoption of FIN 48. Accordingly, we will adopt FIN 48 and FSP No. FIN 48-1 in our fiscal year 2008. We are currently assessing the impact

32


Table of Contents

FIN 48 may have on our consolidated financial statements; however, we believe the adoption of FIN 48 will not have a material impact on our financial position, results of operations or cash flows.
In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (Statement 157). Statement 157 provides enhanced guidance for using fair value to measure assets and liabilities and applies whenever other standards require (or permit) the measurement of assets or liabilities at fair value, but does not expand the use of fair value measurement to any new circumstances. Statement 157 establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, for example, the reporting entity’s own data. Under Statement 157, fair value measurements would be separately disclosed by level within the fair value hierarchy. Statement 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, with earlier application encouraged. Accordingly, we will adopt Statement 157 no later than our first fiscal quarter in 2009. We believe the adoption of Statement 157 will not have a material impact on our financial position, results of operations or cash flows.
In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (Statement 158). Statement 158 requires an employer to fully recognize the obligations associated with single-employer defined benefit pension, retiree healthcare and other postretirement plans in the financial statements by recognizing in its statement of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status rather than only disclosing the funded status in the footnotes to the financial statements. Statement 158 requires employers to recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. Under Statement 158, gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit cost will be recognized in accumulated other comprehensive income (OCI), net of tax effects, until they are amortized as a component of net periodic cost. Statement 158 also requires that the company measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year. We are already in compliance with this requirement as our pension plans’ measurement dates are already the same as our fiscal year end date.
The requirement to recognize the funded status of a benefit plan and the related disclosure requirements initially will apply as of the end of the fiscal year ending after December 15, 2006. Accordingly, we will adopt the funded status portion of Statement 158 as of October 31, 2007. We believe the adoption of Statement 158 will not have a material effect on our financial position, results of operations or cash flows.
Based on a preliminary assessment of prior regulatory treatment of postretirement benefits, management believes that regulatory asset or liability treatment will be afforded to any amounts that would otherwise be recorded in accumulated OCI resulting from the implementation of Statement 158. We intend to meet with our regulators in fiscal year 2007 to discuss the regulatory accounting and rate treatment of the impact of the adoption of Statement 158. Assuming regulatory treatment, if Statement 158 had been adopted for the fiscal year ended October 31, 2006, the effect on the consolidated balance sheets would have been the recognition of $25.6 million as a regulatory asset, $16.7 million of deferred income taxes, $14.6 million decrease to prepaid pension and $27.7 million increase in accrued postretirement benefits. The actual impact at October 31, 2007 could be substantially different depending on the discount rate, asset returns and plan population at that date.
In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (Statement 159). Statement 159 provides companies with an option to report selected financial assets and liabilities at fair value. Its objective is to reduce the complexity in accounting for financial instruments and to mitigate the volatility in earnings caused by measuring related assets and

33


Table of Contents

liabilities differently. Although Statement 159 does not eliminate disclosure requirements included in other accounting standards, it does establish additional presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. Statement 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, with early adoption permitted for an entity that has elected also to apply Statement 157 early. Accordingly, we will adopt Statement 159 no later than our first fiscal quarter in 2009. We believe the adoption of Statement 159 will not have a material impact on our financial position, results of operations or cash flows.

We hold all financial instruments discussed in this item for purposes other than trading. We are potentially exposed to market risk due to changes in interest rates and the cost of gas. Our exposure to interest rate changes relates primarily to short-term debt. We are exposed to interest rate changes to long-term debt when we are in the market to issue long-term debt. As of April 30, 2007, all of our long-term debt was issued at fixed rates. Exposure to gas cost variations relates to the wholesale supply, demand and price of natural gas.
Interest Rate Risk
We have short-term borrowing arrangements to provide working capital and general corporate funds. The level of borrowings under such arrangements varies from period to period depending upon many factors, including our investments in capital projects. Future short-term interest expense and payments will be impacted by both short-term interest rates and borrowing levels.
As of April 30, 2007, we had $29.5 million of short-term debt outstanding under our credit facility at a weighted average interest rate of 5.57%. The carrying amount of our short-term debt approximates fair value. A change of 100 basis points in the underlying average interest rate for our short-term debt would have caused a change in interest expense of $.2 million during the three months ended April 30, 2007 and $.7 million during the six months ended April 30, 2007.
As of April 30, 2007, all of our long-term debt was at fixed interest rates and, therefore, not subject to interest rate risk.
Commodity Price Risk
In the normal course of business, we utilize exchange-traded contracts of various durations for the forward sale and purchase of a portion of our natural gas requirements. We manage our gas supply costs through a portfolio of short- and long-term procurement contracts with various suppliers. Due to cost-based rate regulation in our utility operations, our prudently incurred purchased gas costs, and the prudently incurred costs of hedging our gas supplies are passed on to customers through PGA procedures.
Additional information concerning market risk is set forth in “Financial Condition and Liquidity” in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 2 of this Form 10-Q.

Item 4. Controls and Procedures
Our management, including the President and Chief Executive Officer and the Senior Vice President and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this Form 10-Q. Based on such evaluation, the President and Chief Executive Officer and the Senior Vice President and Chief Financial Officer concluded that, as of the end of the period covered by this Form 10-Q, our disclosure controls and procedures were effective in that they provide reasonable assurances that the information we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods required by the United States Securities and Exchange Commission’s rules and forms.
We routinely review our internal control over financial reporting and from time to time make changes intended to enhance the effectiveness of our internal control over financial reporting. There were no changes to our internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act during the second quarter of fiscal 2007 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Part II. Other Information
Item 1. Legal Proceedings
We have only routine litigation in the normal course of business.
Item 1A. Risk Factors
During the six months ended April 30, 2007, there were no material changes to our risk factors that were disclosed in our Form 10-K for the year ended October 31, 2006.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
     c) Issuer Purchases of Equity Securities.
          The following table provides information with respect to purchases of common stock under the Common Stock Open Market Purchase Program during the three months ended April 30, 2007.

The Common Stock Open Market Purchase Program was announced on June 4, 2004, to purchase up to three million shares of common stock for reissuance under our dividend reinvestment, stock purchase and incentive compensation plans. On December 16, 2005, the Board of Directors approved an increase in the number of shares in this program from three million to six million to reflect the two-for-one stock split in 2004. The Board also approved on that date an amendment of the Common Stock Open Market Purchase Program to provide for the purchase of up to four million additional shares of common stock to maintain our debt-to-equity capitalization ratios at target levels. These combined actions increased the total authorized share repurchases from three million to ten million shares. The additional four million shares are referred to as our accelerated share repurchase program and have an expiration date of December 31, 2010.
The amount of cash dividends that may be paid on common stock is restricted by provisions contained in certain note agreements under which long-term debt was issued, with those for the senior notes being the most restrictive. We cannot pay or declare any dividends or make any other distribution on any class of stock or make any investments in subsidiaries or permit any subsidiary to do any of the above (all of the foregoing being “restricted payments”) except out of net earnings available for restricted payments. As of April 30, 2007, net earnings available for restricted payments were greater than retained earnings; therefore, our retained earnings were not restricted.
Item 4. Submission of Matters to a Vote of Security Holders
We held our Annual Meeting of Shareholders on March 7, 2007, to elect five directors and to ratify the selection of our independent registered public accounting firm. The record date for determining the shareholders entitled to receive notice of and to vote at the meeting was January 16, 2007.

PIEDMONT NATURAL GAS COMPANY, INC.
SHORT-TERM INCENTIVE PLAN (STIP)
     Piedmont Natural Gas Company, Inc. (the “Company”) and                      (“Participant”) hereby enter into this Participation Agreement (“Agreement”) as of                      , 20___, for fiscal 20___ Short-Term Incentive Plan awards under the Piedmont Natural Gas Company, Inc. Incentive Compensation Plan (the “ICP”).
     WHEREAS, on March 3, 2006, the Company’s shareholders approved the ICP; and
     WHEREAS, on                      , 20___, the Company’s Board of Directors adopted a resolution defining weights, measures, targets and participants for the fiscal 20___ Short-Term Incentive Plan awards (“20___ STIP Plan”).
     NOW, THEREFORE, in consideration of these premises and the mutual promises contained herein, the parties hereto hereby agree as follows:
1.  Designation as a Participant. You have been designated as a Participant under the 20___ STIP Plan for the fiscal year 20___. Exhibit A attached hereto identifies the target award applicable to you. The award is a cash payment. Subject to the Company’s Stock Ownership Guidelines, if you do not meet your stock ownership goal due to stock dispositions, you will be required to use a minimum of 25% (net of applicable taxes) of any amounts awarded hereunder to purchase Company common stock until the applicable ownership level is achieved. As a participant, you shall be subject to all the terms and conditions of the ICP and this Participation Agreement.
2.  Performance Period. The fiscal year 20___ STIP Plan performance period begins November 1, 20___ and ends October 31, 20___ (the “Performance Period”).
3.  Performance Goals. The fiscal year 20___ STIP Plan performance goals are established by the Board of Directors. The table below identifies the performance/payment relationship for the fiscal year 20___ STIP Plan.
     
    Payout as a Percent of Incentive
Performance Against EPS Goal   Opportunity
> = 105% of Goal
  150%
100% of Goal
  100%
95% of Goal
  50%
< 95% of Goal
  0%

 


 

     Payouts for performance between 95% and 105% of goal will be subject to mathematical interpolation.
     After the end of fiscal year 20___, the Board of Directors will verify achievement of performance goals and declare the appropriate distribution of 20___ STIP Plan awards.
4. Tax Withholding. The Company will withhold any required taxes for any target awards distributed to you in compliance with tax withholding regulations.
5. ICP . The Participant acknowledges that the grant and distribution of an award to him/her under the 20___ STIP Plan is governed by the terms of the ICP, as amended from time to time, and the terms of the ICP as they exist on the date of this Agreement are incorporated into this Agreement in their entirety and made a part hereof by reference. Unless otherwise defined herein, capitalized terms used herein shall have the meaning set forth in the ICP. In the event of any conflict between the terms of the ICP and this Agreement, the terms of the ICP shall control.
6. Board Authority . The Compensation Committee of the Board of Directors shall have authority to administer and interpret the 20___ STIP Plan and to establish rules for its administration. The Participant acknowledges that the award hereunder shall be governed by guidelines and interpretations with respect to short-term incentive plan awards adopted by the Board or Compensation Committee under the ICP from time to time.
7. Modifications . If any provision or provisions of the ICP or this Agreement would cause any amount to be includible in gross income of the Participant prior to the Company’s scheduled payment of such amount to the Participant provided for herein or subject such Participant to penalties or interest under Section 409A of the Internal Revenue Code of 1986, as amended, such provision or provisions shall be interpreted or modified to the extent necessary so that no such amount will be included in such Participant’s gross income prior to its scheduled payment by the Company provided for herein and no such penalties or interest will be incurred. This Agreement constitutes the entire understanding of the parties on the subjects covered. The Participant expressly warrants that he/she is not accepting this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Except with respect to modifications of the ICP as provided therein and guidelines and interpretations under the ICP adopted by the Board or Compensation Committee that are not materially inconsistent with the terms of this Agreement, this Agreement can be amended only in writing executed by the Participant and a duly authorized officer of the Company.
8. Binding Nature; Governing Law . Subject to any limitations under the ICP on transferability, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. This Agreement shall be governed by the laws of the State of North Carolina to the extent not preempted by applicable federal law.
