PART I

General and Historical Development

Resources was incorporated in the state of Virginia on July 31, 1998, for the primary purpose of becoming the holding company for Roanoke Gas Company (“Roanoke Gas”) and its subsidiaries. Effective July 1, 1999, Roanoke Gas and its subsidiaries were reorganized into the holding company structure. Resources is currently composed of the following subsidiaries: Roanoke Gas, Diversified Energy Company and RGC Ventures of Virginia, Inc.

Roanoke Gas was organized as a public service corporation under the laws of the Commonwealth of Virginia in 1912. The principal service of Roanoke Gas is the distribution and sale of natural gas to residential, commercial and industrial customers within its service territory in Roanoke, Virginia and the surrounding localities. Roanoke Gas also provides certain non-regulated services which account for most of the non-gas utility revenue of Resources.

In 2000, the information technology department of Resources formed Application Resources, Inc. under RGC Ventures of Virginia, Inc. to provide information technology consulting services. In 2011, the Company also formed The Utility Consultants under RGC Ventures of Virginia, IncInc. to provide utility and regulatory consulting services to other utilities. The operations of RGC Ventures of Virginia, Inc. contributed less than 6%2% of the other revenues of Resources.Resources during fiscal 2013. Diversified Energy Company currently has no active operations.

Services

RGC Resources, Inc. is an energy services company engaged in the sale and distribution of natural gas through its Roanoke Gas subsidiary. Roanoke Gas maintains an integrated natural gas distribution system to deliver natural gas purchased from suppliers to residential, commercial and industrial users in its service territory. The schedule below is a summary of customers, delivered volumes (expressed in decatherms), revenues and margin as a percentage of the total for each category:

The industry standard for the unit of measure for natural gas is a decatherm (“DTH”), which is the heat equivalent of one million BTU where one BTU is equal to the amount of heat required to raise the temperature of one pound of liquid water by one degree Fahrenheit.

Roanoke Gas’ regulated natural gas distribution business accounted for approximately 98% of Resources total revenues and gross margin for fiscal years ending September 30, 2012, 2011 and 2010, and 98% of total gross margin for the fiscal years ended September 30,2013, 2012 and 2011 and 97% of total margin for fiscal year ended September 30, 2010.2011. The table above indicates that residential customers represent over 90% of the Company’s customer total; however, they represent less than 50% of the total gas volumes delivered and just over half of the Company’s consolidated margin. Industrial customers include primarily transportation customers that purchase their natural gas requirements directly from a supplier other than the Company and utilize Roanoke Gas’ natural gas distribution system for delivery to their operations. As a result mostMost of the revenue billed for these customers relates only to transportation service and not to the purchase of natural gas, causing total revenues generated by these deliveries to be approximately 8% of total revenues6% even though they represent 36%31% of total natural gas deliveries and approximately 12% of gross margin.

The Company’s revenues are affected by changes in gas costs as well as by changes in consumption volume due to weather and economic conditions and changes in the non gasnon-gas portion of customer billing rates. Increases or decreases in the cost of natural gas are passed on to customers through the purchased gas adjustment mechanism as explained in further detail in Note 1 of the Company’s annual consolidated financial statements. Significant increases in gas costs may cause customers to conserve, or primarily in the case of industrial customers, to use alternative energy sources.

The Company’s residential and commercial sales are seasonal andtemperature-sensitive as the majority of the gas sold by Resources to these customers is used for heating. For the fiscal year ended September 30, 2012,2013, approximately 62%66% of the Company’s total DTH of natural gas deliveries and 72%75% of the residential and commercial deliveries were made in the five-month period of November through March. This represents a reductionan increase of 6%4% in total and 3% in residential and commercial deliveries from last year for the same period. The declineincrease in volume is attributable to the current fiscal year having 22% fewer25% more heating degree days. The Company was able to mitigate the effect of most of the lost margin from the volume decline through the weather normalization adjustment mechanism (“WNA”) approved tariff. Further explanation regarding WNA may be found under the Overview section of Management’s Discussion and Analysis. Total natural gas deliveries were 9.4 million DTH, 8.3 million DTH 9.5 million DTH and 9.39.5 million DTH in fiscal 2013, 2012 and 2011, and 2010, respectively.

Suppliers

Roanoke Gas relies on multiple interstate pipelines including those operated by Columbia Gas Transmission Corporation and Columbia Gulf Transmission Corporation (together “Columbia”), and East Tennessee Natural Gas Company (“East Tennessee”), Tennessee Gas Pipeline, Midwestern Gas Transmission and Saltville Gas Storage Company, LLC to transport natural gas from the production and storage fields to Roanoke Gas’ distribution system. Roanoke Gas is directly served by two pipelines, Columbia and East Tennessee. Columbia historically has delivered approximately 55% of the Company’s gas supply, while East Tennessee delivers the balance of the Company’s requirements. The rates paid for natural gas transportation and storage services purchased from the interstate pipeline companies are established by tariffs approved by FERC (Federal Energy Regulatory Commission). These tariffs contain flexible pricing provisions, which, in some instances, authorize these transporters to reduce rates and charges to meet price competition. The current pipeline contracts expire at various times from 20132014 to 2019.2020. The Company anticipates being able to renew these contracts or enter into other contracts to meet customers’ continued demand for natural gas.

The Company manages its pipeline contracts and liquefied natural gas storage (“LNG”) facility in order to provide for sufficient capacity to meet the natural gas demands of its customers. The maximum daily winter capacity for delivery into Roanoke Gas’ distribution system under the interstate pipelines is 78,606 DTH per day. The LNG facility, which is capable of storing up to 220,000 DTH of natural gas in a liquid state for use during peak demand, has the capability of providing an additional 33,000 DTH per day. Combined, the pipelines and LNG facility can provide more than 111,000 DTH on a single winter day. In fiscal 2012,2013, the Company realized a maximum one day-customer demand of 71,32871,048 DTH.

The Company uses multi-year contracts to meet its natural gas supply needs. The Company currently contractspreviously had contracted with ConocoPhillips to provide asset management services and be the primary supplier of natural gas for Roanoke Gas. Effective November 1, 2013, Sequent Energy Management, L.P. assumed the asset manager and primary supplier for Roanoke Gas.function under terms similar to the expiring contract. Natural gas purchased under the asset manager agreement is priced at indexed-based market prices as reported in major industry pricing publications. The Company expects its firm supply agreements will be sufficient to meet customer demands for natural gas during the term of the agreement.

The Company uses summer storage programs to supplement gas supply requirements during the winter months. During the summer months, the Company injects gas into its LNG facility. In addition, the Company has contracted for storage capacity from Columbia, Tennessee Gas Pipeline and Saltville Gas Storage Company, LLC for a combined total of more than 2.62.4 million DTH of storage capacity. The balance of the Company’s annual natural gas requirements are met primarily through market purchases made by its asset manager who also manages its pipeline transportation and storage rights and gas supply inventories and deliveries.

Competition

The Company’s natural gas utility operates in a regulated, monopolistic environment. Roanoke Gas currently holds the only franchises and/or certificates of public convenience and necessity to distribute natural gas in its Virginia service areas. These franchises generally extend formulti-year periods and are renewable by the municipalities, including exclusive franchises in the cities of Roanoke and Salem and the Town of Vinton, Virginia, which all expire December 31, 2015.

Management anticipates that the Company will be able to renew all of its franchises when they expire. There can be no assurance, however, that a given jurisdiction will not refuse to renew a franchise or will not, in connection with the renewal of a franchise, attempt to impose restrictions or conditions that could adversely affect the Company’s business operations or financial condition. Certificates of public convenience and necessity, issued by the Virginia State Corporation Commission (the “SCC”), are of perpetual duration, subject to compliance with regulatory standards.

Although Roanoke Gas has exclusive rights for the distribution of natural gas in its service area, the Company competes with suppliers of other energy sources such as fuel oil, electricity, propane and coal. Competition can be intense among the other energy sources and can be based primarily on price. This is particularly true for those industrial applications that have the ability to switch to other fuels. The relationship between supply and demand has the greatest impact on the price of natural gas. Greater demand for natural gas for electric generation and other uses combined with limited domestic supplies can provide upward pressure on the price of natural gas. The Company continues to see a demand for its product and extends service to the new residential construction markets located along or near gas distribution mains in its service area. However, as the economic environment has limited new construction activity, since 2008, and the rate of new customer growth has remained below historical levels.

Regulation

Roanoke Gas is subject to regulation at the federal, state and local levels. At the federal level, the Company is subject to pipeline safety regulations issued by the Department of Transportation and the Pipeline and Hazardous Materials Safety Administration.

At the state level, regulation is performed by the SCC and includes the approval of rates and charges at which natural gas is sold to customers, the approval of agreements between or among affiliated companies involving the provision of goods and services, pipeline safety, and certain other corporate activities of the Company, including mergers and acquisitions related to utility operations. The SCC also grants certificates of public convenience and necessity to distribute natural gas in Virginia.

At the local level, Roanoke Gas is further regulated by the municipalities and localities that grant franchises for the placement of gas distribution pipelines and the operation of gas distribution networks within the streets and alleys of their jurisdictions.

Employees

At September 30, 2012,2013, Resources had 117 120full-time employees and 120127 total employees. As of that date, 3435 employees, or 29% of the Company’sfull-time employees, belonged to the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied-Industrial International Union, Local No. 515 and were represented under a collective bargaining agreement. The union has been in place at the Company since 1952. The current collective bargaining agreement will expire on July 31, 2015. Management maintains an amicable relationship with the union.

Please carefully consider the risks described below regarding the Company. The risks described below are not the only ones faced by the Company. Additional risks not presently known to the Company or that the Company currently believes are immaterial may also impair business operations and financial results. If any of the following risks actually occurs, the Company’s business, financial condition or results of operations could be adversely affected. In such case, the trading price of the Company’s common stock could decline and an investor could lose all or part of his, her or its investment.

Increased compliance and pipeline safety requirements and fines.

The Company is committed to the safe and reliable delivery of natural gas to its customers. Working in concert with this commitment are numerous laws and regulations derived at both the federal and state levels. The Company is diligent in complying with these regulations and is subject to ongoing inspections and reviews. Failure to comply with such requirements could result in the levy of significant fines. Recent enforcement actions by the Virginia Division of Utility and Railroad Safety have resulted in increased fine levels for gas distribution companies across the state of Virginia. There are inherent risks that may be beyond the Company’s control, including third party actions, which could result in damage to the pipeline facilities, injury and even death. Such incidents could subject the Company to lawsuits, large fines, increased scrutiny and loss of customers, all of which could have a significant effect on the Company’s financial position and results of operation.

Weather conditions may cause revenues and earnings to vary from year to year.

The Company’s revenues and earnings are highly dependent upon weather conditions, specifically winter weather. A warm winter can reduce energy consumption and therefore lower the volume of gas delivered, which reduces revenue and earnings. The Company’s rate structure currently has a weather normalization adjustment factor that operates around a weather band of approximately 3% above and below the 30-year average for heating degree-days. This weather band significantly reduces the weather risk exposure by limiting the impact of warmer than normal weather to no more than 3% from the 30-year average. Conversely, the protection provided by the weather band to the downside risk also limits the upside potential from colder than normal weather by the same 3%. If the provision for the weather normalization adjustment were removed from its rate structure, the Company would be exposed to a much greater risk related to weather variability resulting in earnings volatility.

Competition from other energy providers.

The Company competes with other energy providers in its service territory, including those that provide electricity, propane, coal and fuel oil. A significant competitive factor is price. Higher natural gas costs or decreases in the price of other energy sources may lead to competition and encourage customers to convert their gas-fired equipment to systems that use alternative energy sources, thus lowering natural gas deliveries and earnings. Price considerations could also inhibit customer and revenue growth if builders and developers do not perceive natural gas to be a better value than other energy options and elect to install heating systems that use an energy source other than natural gas.

Business activities are concentrated in a limited geographic region.

Changes in the Roanoke Valley’s economies, politics, regulations and weather patterns could negatively impact the existing customer base, leading to declining usage patterns and financial condition of customers, both of which could adversely affect earnings.

General downturn in the economy or prolonged period of slow economic recovery.

A weak or poorly performing economy can negatively affect the Company’s profitability. An economic downturn can result in loss of commercial and industrial customers due to plant closings as well as slow or declining growth in new customer additions, both of which would result in reduced sales volumes and lower revenues. An economic downturn could also result in rising unemployment and other factors that could result in increased customer delinquencies and bad debt expense.

Availability of adequate and reliable pipeline capacity.

The Company is served directly by two interstate pipelines. These two pipelines carry 100% of the natural gas transported to the Company’s distribution system. Depending on weather conditions and the level of customer demand, failure of one or both of these interstate transmission pipelines could have a major impact on the Company’s ability to meet customer demand for natural gas and adversely affect the Company’s earnings as a result of lost revenue and the cost of service restoration.

Supply disruptions due to weather or other forces.

Hurricanes and other natural or man made disasters could damage or inhibit production and/or pipeline transportation facilities, which could result in decreased supplies of natural gas. Decreased supplies could result in an inability to meet customer demand leading to higher prices or service disruptions. Disasters could also lead to additional governmental regulations that limit production activity or increase production and transportation costs.

Competition from other energy providers.

The Company competes with other energy providers in its service territory, including those that provide electricity, propane, coal and fuel oil. A significant competitive factor is price. Higher natural gas costs or decreases in the price of other energy sources may lead to competition and encourage customers to convert their gas-fired equipment to systems that use alternative energy sources, thus lowering natural gas deliveries and earnings. Price considerations could also inhibit customer and revenue growth if builders and developers do not perceive natural gas to be a better value than other energy options and elect to install heating systems that use an energy source other than natural gas.

Business activities are concentrated in a limited geographic region.

Changes in the Roanoke Valley’s economies, politics, regulations and weather patterns could negatively impact the existing customer base, leading to declining usage patterns and financial condition of customers, both of which could adversely affect our earnings.

Environmental laws or regulations.

Passage of new environmental legislation or implementation of regulations that mandate reductions in greenhouse gas emissions or other similar restrictions could have a negative effect on the Company’s core operations. Natural gas is a clean and efficient energy source; however, the combustion of natural gas results in carbon related emissions. Such legislation could impose limitations on greenhouse gas emissions, require funding of new energy efficiency objectives, impose new operational requirements or lead to other additional costs to the Company. New regulations could result in a significant reduction in the use of coal as a fuel for electric power generation, potentially resulting in natural gas supply concerns and higher cost for natural gas. Legislation or regulations could limit the exploration and development of natural gas reserves, making the price of natural gas less competitive and less attractive as a fuel source for consumers, resulting in reduced deliveries and earnings.

Supply disruptions due to weather or other forces.

Hurricanes and other natural or man-made disasters could damage or inhibit production and/or pipeline transportation facilities, which could result in decreased supplies of natural gas. Decreased supplies could result in an inability to meet customer demand leading to higher prices or service disruptions. Disasters could also lead to additional governmental regulations that limit production activity or increase production and transportation costs.

The cost of providing post-retirement benefits and related funding obligations may increase.

The costs of providing defined benefit pension and retiree medical plans are dependent on a number of factors such as the rates of return on plan assets, discount rates used in determining plan liabilities, the level of interest rates used to measure the required minimum funding levels of the plan, future government regulation, changes in life expectancy, and required or voluntary contributions made to the plan. Changes in actuarial assumptions and differences between the assumptions and actual results, as well as a significant decline in the value of investments that fund these plans, if not offset or mitigated by a decline in plan

liabilities, could increase the expense of these plans and require significant additional funding of these plans. Such funding obligations could have a material impact on liquidity by reducing cash flows and could negatively affect results of operations.

Security breach or cyber attackscyber-attacks on the Company’s computer systems could corrupt financial information, expose confidential personal information or compromise the safe and reliable delivery of natural gas.

A breach of the Company’s information systems from cyber-attacks or other sources could lead to disruptions in natural gas deliveries or compromise the safety of our distribution system. Such attacks could also result in corruption of the Company’s financial information or the unauthorized release of confidential customer, employee or vendor information. The Company takes reasonable precautions to safeguard its computer systems from attack; however, there is no guarantee that Company processes will adequately protect against unauthorized access to data. In the event of a successful attack, the Company could be exposed to material financial and reputational risk.risks.

Increased compliance and pipeline safety requirements.

The Company is committed to the safe and reliable delivery of natural gas to its customers. Working in concert with this commitment are numerous laws and regulations derived at both the federal and state levels. The Company is diligent in complying with these regulations and is subject to ongoing inspections and reviews. Failure to comply with such requirements could result in the levy of significant fines. There are inherent risks that may be beyond the Company’s control, including third party actions, which could result in damage to the pipeline facilities, injury and even death. Such incidents could subject the Company to lawsuits, fines, increased scrutiny and loss of customers, all of which could have a significant effect on the Company’s financial position and results of operation.

Changes in accounting standards and their effect on the financial statements.

The SEC is currently evaluating the potential ofcontinues to evaluate requiring public issuers in the United States to adopt International Financial Reporting Standards (IFRS) and prepare financial statements in accordance with these rulesInternational Financial Reporting Standards (IFRS) instead of the current generally accepted accounting principles (GAAP) used in the United States. IFRS is a principalsprinciples based set of accounting standards promulgated by the International Accounting Standards Board (IASB), which are currently in effect for most other countries in the world.. The application of IFRS would result in differences in the components of a company’s financial statements as a result of differences between IFRS and GAAP. One major difference is IFRS does not currently provide an industry accounting standard for rate-regulated activities. As such, the adoption of IFRS in its current form, without other mitigating regulatory actions, could result in the Company no longer recognizing regulatory assets and liabilities on its financial statements which could have a significant effect on the Company’s financial condition and results of operations. The Financial Accounting Standards Board (FASB), the governing body in the United States, could also issue new accounting standards that would have a significant impact on the Company’s financial statements and increase the Company’s cost of compliance.

Access to capital to maintain liquidity.

The Company relies on a variety of capital sources to operate its business and fund capital expenditures, including internally generated cash from operations, short-term borrowings under its line-of-credit, proceeds from stock issued under the Dividend Reinvestment and Stock Purchase Plan (“DRIP”) and other sources. Access to a bank line-of-credit is essential to provide seasonal funding of natural gas operations and provide capital budget bridge financing. Access to capital markets and other long-term funding sources is important to provide more predictable financing for capital outlays. The ability of the Company to maintain and renew its line-of-credit and to secure longer-term financing is critical to operations. Adverse market trends or deterioration in the financial condition of the Company could increase the cost of borrowing or limit the Company’s ability to secure adequate funding.

Risks associated with the operation of a natural gas distribution pipeline and LNG storage facility.

Numerous potential risks are inherent in the operation of a natural gas distribution system and LNG storage facility including unanticipated or unforeseen events that are beyond the control of the Company. Examples of such events include adverse weather conditions, acts of terrorism, accidents, equipment breakdowns, failure of upstream pipelines and storage facilities, as well as catastrophic events such as explosions, fires, earthquakes, floods, or other similar events. These risks could result in injury or loss of life, property damage, pollution and customer service disruption resulting in potentially significant financial losses. The Company maintains insurance policies with financially sound carriers to protect

against many of these risks. If losses result from a risk that is not fully covered by insurance, the Company’s financial condition could be significantly impacted if it were unable to recover such losses from customers through the regulatory rate making process. Even if the Company did not incur a direct financial loss as a result of any of the events noted above, it could encounter significant reputational damage from a reliability, safety, integrity or similar viewpoint, ultimately resulting in longer-term earnings impact.

Regulatory actions or failure to obtain timely rate relief could decrease future profitability.

The Company’s natural gas operations are regulated by the SCC. The SCC approves the rates that we charge our natural gas customers. If the SCC did not allow rates that provided for the timely recovery of our costs or a reasonable rate of return on our investment in natural gas distribution facilities, our earnings could be negatively impacted. Our debt and equity financings are also subject to SCC regulation and approval. Delays or lack of approvals could inhibit our ability to access capital markets and negatively impact our liquidity or earnings.

Inability to attract and maintain adequate staffing could affect operations.

The Company is dependent on competent management and other professionally or technically trained employees for the safe, reliable and profitable operations of its natural gas distribution facilities. Aging of the work force and the choice by younger replacement workers not to accept employment in the natural gas and utility service industries could result in worker shortages and inhibit the Company’s ability to meet customer service needs and regulatory requirements.

Volatility in the price and availability of natural gasgas.

Natural gas represents the single largest expense of the Company. Recent improvements in the technologies needed for accessing the natural gas contained in shale rock have been the primary factor in the decline in natural gas commodity prices as these natural gas reserves are now accessible. Even with increasing demand from other areas including electric generation, natural gas prices are currently expected to remain stable in the near term, although there can be no guarantee to that effect. However, if restrictions on drilling for natural gas in the shale rock formations are imposed at either federal or state levels due to environmental or other concerns or other exploration and development restrictions on conventional drilling are enacted, the price of natural gas could escalate. Furthermore, if demand for natural gas increases at a rate in excess of current expectations, natural gas prices could also face upward pressure. Increasing natural gas prices could make natural gas a less attractive energy source to the Company’s customers; thereby potentially resulting in declining sales as well as increases in bad debt expense.

Regulatory actions or failure to obtain timely rate relief could decrease future profitability.

The Company’s natural gas operations are regulated by the SCC. The SCC approves the rates that the Company charges its natural gas customers. If the SCC did not allow rates that provided for the timely recovery of costs or a reasonable rate of return on investment in natural gas distribution facilities, earnings could be negatively impacted. Debt and equity financings are also subject to SCC regulation and approval. Delays or lack of approvals could inhibit the ability to access capital markets and negatively impact liquidity or earnings.

Inability to attract and maintain adequate staffing could affect operations.

The Company is dependent on competent management and other professionally or technically trained employees for the safe, reliable and profitable operations of its natural gas distribution facilities. Aging of the work force and the choice by younger replacement workers not to accept employment in the natural gas and utility service industries could result in worker shortages and inhibit the Company’s ability to meet customer service needs and regulatory requirements.

Effect of the federal budget deficit on corporate tax structure and the economic environment.

The United States budget has been operating at a deficit of more than a trillion dollars annually during the last few years. The result is an increasing debt level byof the United States government that will require greater resources to meet debt servicing needs. In order to reduce the growth in government debt, Congress and the Presidency will need to take actions that may include increasing tax revenues and decreasing governmental spending. The federal government could increase tax revenue by raising tax rates or eliminating deductions, either of which could increase the Company’s tax liability. Reduction in government spending could push the economy back into a recession which could lead to a decline in natural gas sales due to reduced economic production and higher bad debt expense due to the inability of some customers to pay their bills. Either or both of these scenarios could have a negative effect on the Company’s financial position and results of operation.

Inability to complete necessary or desirable pipeline expansion or infrastructure development projects may delay or prevent the Company from adequately serving its customers or expanding its distribution system.

In order to serve new customers or expand service to existing customers, the Company needs to maintain, expand or upgrade its distribution, transmission and/or storage infrastructure, including new pipeline installation. Various factors may prevent or delay the completion of such projects or make them more costly, such as the inability to obtain required approval from local, state and/or federal regulatory and governmental bodies, public opposition to the projects, inability to obtain adequate financing, competition for labor and materials, construction delays, cost overruns, and an inability to negotiate acceptable agreements relating to rights-of-way, construction or other material development components. As a result, the Company may not be able to adequately serve existing customers or support customer growth, which would negatively impact earnings.

Not applicable.

Included in “Utility Plant” on the Company’s consolidated balance sheet are storage plant, transmission plant, distribution plant and general plant of Roanoke Gas as categorized by natural gas utilities. The Company has approximately 1,0531,056 miles of transmission and distribution pipeline with transmission and distribution plant representing almost 87%more than 86% of the total investment in plant. The transmission and distribution pipelines are located on or under public roads and highways or private property for which the Company has obtained the legal authorization and rights to operate these facilities on such property.

Roanoke Gas owns and operates eight metering stations through which it measures and regulates the gas being delivered by its suppliers. These stations are located at various points throughout the Company’s distribution system.

Roanoke Gas also owns a liquefied natural gas storage facility located in Botetourt County that has the capacity to store up to 220,000 DTH of natural gas.

The Company’s executive, accounting and business offices, along with its maintenance and service departments, are located on Kimball Avenue in Roanoke, Virginia.

Although the Company considers its present properties adequate, management intends to complete the replacement of its remaining cast iron and bare steel pipeline within the next sixfour years.

The Company is a defendant in two civil lawsuits associated with a November 2009 explosion and fire at a West Virginia residence, allegedly due to propane ignition. This residence was served by a propane tank installed prior to the 2004 sale of Highland Propane assets (the Company’s former subsidiary) to Inergy Propane, LLC (“Inergy”).

The Company is exposed to market risks through its natural gas operations associated with commodity prices. The Company’s hedging and derivatives policy, as authorized by the Company’s Board of Directors, allows management to enter into both physical and financial transactions for the purpose of managing the commodity risk of its business operations. The policy also specifies that the combination of all commodity hedging contracts for any 12-month period shall not exceed a total hedged volume of 90% of projected volumes. Finally, theThe policy specifically prohibits the use of derivatives for the purposes of speculation.

The Company manages the price risk associated with purchases of natural gas by using a combination of liquefied natural gas (LNG) storage, underground storage gas, fixed price contracts, spot market purchases and derivative commodity instruments including futures, price caps, swaps and collars.

The SCC currently allows for full recovery of prudent costs associated with natural gas purchases, and any additional costs or benefits associated with the settlement of the derivative

contracts and other price hedging techniques are passed through to customers when realized through the regulated natural gas PGA mechanism.

The Company is also exposed to market risk related to changes in interest rates associated with its borrowing activities. As of September 30, 2012,2013, the Company has a $15,000,000 variable rate note payable due March 31, 20132014 and a $5,000,000 intermediate term variable rate note due December 1, 2015.

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to be effective in providing reasonable assurance that information required to be disclosed in reports under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (the “SEC”), and that such information is accumulated and communicated to management to allow for timely decisions regarding required disclosure.

As of September 30, 2012,2013, the Company completed an evaluation, under the supervision and with the participation of management, including the chief executive officer and the chief financial officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based upon that evaluation, the chief executive officer and chief financial officer concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2012.2013.

Management routinely reviews the Company’s internal control over financial reporting and makes changes, as necessary, to enhance the effectiveness of the internal controls over financial reporting. There were no changes in the internal controls over financial reporting during the fourth quarter of the fiscal year covered by this report that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) under the Securities and Exchange Act of 1934.) Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America and include those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of the management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations, any system of internal control over financial reporting, no matter how well designed, may not prevent or detect misstatements due to the possibility that a control can be circumvented or overridden or that misstatements due to error or fraud may occur that are not detected. Projections of the effectiveness to future periods are subject to the risk that the internal controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures included in such controls may deteriorate. The Company’s internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

The Company has conducted an evaluation of the design and effectiveness of the Company’s system of internal control over financial reporting as of September 30, 2012,2013, based on the framework set forth in “Internal Control - Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based upon such evaluation, the Company concluded that, as of September 30, 2012,2013, the Company’s internal control over financial reporting was effective.

The Company’s independent registered public accounting firm, Brown, Edwards & Company, LLP, has issued its report on the effectiveness of the Company’s internal control over financial reporting as of September 30, 2012.2013.

We have audited RGC Resources, Inc. and Subsidiaries (“the Company”)’s internal control over financial reporting as of September 30, 2012,2013, based on criteria established inInternal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). RGC Resources, Inc. and Subsidiaries’ management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, RGC Resources, Inc. and Subsidiaries (“the Company”) maintained, in all material respects, effective internal control over financial reporting as of September 30, 2012,2013, based on criteria established inInternal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
