      NOTE
      A – SUMMARY OF ACCOUNTING POLICIES
     
      A
      summary of the significant accounting policies applied in the
      preparation of the accompanying condensed consolidated
      financial statements follows.
     
      General
     
      The
      restated condensed consolidated balance sheet as of December
      31, 2010 and the restated condensed consolidated statement of
      stockholders’ equity for the year ended December 31,
      2010 have been derived from the restated financial
      statements. The accompanying unaudited condensed consolidated
      financial statements of Telkonet, Inc. (the
      “Company”) have been prepared in accordance with
      Rule S-X of the Securities and Exchange Commission (the
      “SEC”) and with the instructions to Form 10-Q.
      Accordingly, they do not include all of the information and
      footnotes required by generally accepted accounting
      principles for complete financial statements.
     
      In
      the opinion of management, all adjustments (consisting of
      normal recurring accruals) considered necessary for a fair
      presentation have been included.  However, the
      restated results from operations for the three and six month
      periods ended June 30, 2011 and 2010, are not necessarily
      indicative of the results that may be expected for the year
      ending December 31.  The unaudited condensed
      consolidated financial statements should be read in
      conjunction with the consolidated financial statements and
      footnotes thereto included in the Company's Form 2011 10-K to
      be filed hereafter with the SEC.
     
      Business
      and Basis of Presentation
     
      Telkonet,
      Inc., formed in 1999 and incorporated under the laws of the
      state of Utah, has evolved into a Clean Technology company
      that develops, manufactures and sells proprietary energy
      efficiency and SmartGrid networking technology. Prior to
      January 1, 2007, the Company was primarily engaged in the
      business of developing, producing and marketing proprietary
      equipment enabling the transmission of voice and data
      communications over a building’s internal electrical
      wiring.
     
      In
      March 2007, the Company acquired substantially all of the
      assets of Smart Systems International (“SSI”), a
      leading provider of energy management products and solutions
      to customers in the United States and Canada.
     
      In
      March 2007, the Company acquired 100% of the outstanding
      membership units of EthoStream, LLC, a network solutions
      integration company that offers installation, sales and
      service to the hospitality industry. The EthoStream
      acquisition enabled Telkonet to provide installation and
      support for PLC products and third party applications to
      customers across North America.
     
      In
      March 2011, the Company sold all its Series 5 PLC product
      line assets to Wisconsin-based Dynamic Ratings, Inc. under an
      Asset Purchase Agreement.
     
      The
      condensed consolidated financial statements include the
      accounts of the Company and its wholly-owned subsidiaries,
      Telkonet Communications, Inc., and EthoStream, LLC.
      Significant intercompany balances and transactions have been
      eliminated in consolidation.
     
      Going
      Concern
     
      The
      accompanying condensed consolidated financial statements have
      been prepared in conformity with accounting principles
      generally accepted in the United States of America, which
      contemplate continuation of the Company as a going concern.
      The Company has reported net income of $1,103,093 for the six
      month period ended June 30, 2011, accumulated deficit of
      $115,338,864 and total current liabilities in excess of
      current assets of $1,026,103 as of June 30, 2011. The
      accompanying financial statements do not include any
      adjustments that might result from the outcome of these
      uncertainties.
     
      We
      continue to experience net operating losses and deficits in
      cash flows from operations.  Our ability to
      continue as a going concern is subject to our ability to
      generate a profit and/or obtain necessary funding from
      outside sources, including by the sale of our securities or
      assets, or obtaining loans from financial institutions, where
      possible.  Our continued net operating losses and
      the uncertainty regarding contingent liabilities cast doubt
      on our ability to meet such goals and the Company cannot make
      any representations for fiscal 2012 and beyond.
     
      The
      Company believes that anticipated revenues from operations
      will be insufficient to satisfy its ongoing capital
      requirements for at least the next 12 months.  If
      the Company’s financial resources from operations are
      insufficient, the Company will require financing in addition
      to the funds received from the sale of the Series 5 product
      line in order to execute its operating plan and continue as a
      going concern. The Company cannot predict whether this
      additional financing will be in the form of equity or debt,
      or be in another form. The Company may not be able to obtain
      the necessary additional capital on a timely basis, on
      acceptable terms, or at all.  In any of these
      events, the Company may be unable to implement its current
      plans for expansion, repay its debt obligations as they
      become due, or respond to competitive pressures, any of which
      circumstances would have a material adverse effect on its
      business, prospects, financial condition and results of
      operations.
     
      Management intends
      to review the options for raising capital including, but not
      limited to, through asset-based financing, private
      placements, and/or disposition.  Management
      believes that with this financing, the Company will be able
      to generate additional revenues that will allow the Company
      to continue as a going concern. There can be no
      assurance that the Company will be successful in obtaining
      additional funding.
     
      Fair
      Value of Financial Instruments
     
      The
      Company accounts for the fair value of financial instruments
      in accordance with Accounting Standards Codification (ASC)
      820, which defines fair value for accounting purposes,
      established a framework for measuring fair value and expanded
      disclosure requirements regarding fair value
      measurements.  Fair value is defined as an exit
      price, which is the price that would be received upon sale of
      an asset or paid upon transfer of a liability in an orderly
      transaction between market participants at the measurement
      date.  The degree of judgment utilized in measuring
      the fair value of assets and liabilities generally correlates
      to the level of pricing observability.  Financial
      assets and liabilities with readily available, actively
      quoted prices or for which fair value can be measured from
      actively quoted prices in active markets generally have more
      pricing observability and require less judgment in measuring
      fair value.  Conversely, financial assets and
      liabilities that are rarely traded or not quoted have less
      price observability and are generally measured at fair value
      using valuation models that require more
      judgment.  These valuation techniques involve some
      level of management estimation and judgment, the degree of
      which is dependent on the price transparency of the asset,
      liability or market and the nature of the asset or
      liability.  We have categorized our financial
      assets and liabilities that are recurring, at fair value into
      a three-level hierarchy in accordance with these
      provisions.
     
      Goodwill
      and Other Intangibles
     
      Goodwill
      represents the excess of the cost of businesses acquired over
      fair value or net identifiable assets at the date of
      acquisition.  Goodwill is subject to a periodic
      impairment assessment by applying a fair value test based
      upon a two-step method.  The first step of the
      process compares the fair value of the reporting unit with
      the carrying value of the reporting unit, including any
      goodwill.  We utilize a discounted cash flow
      valuation methodology to determine the fair value of the
      reporting unit.  If the fair value of the reporting
      unit exceeds the carrying amount of the reporting unit,
      goodwill is deemed not to be impaired in which case the
      second step in the process is unnecessary.  If the
      carrying amount exceeds fair value, we perform the second
      step to measure the amount of impairment loss.  Any
      impairment loss is measured by comparing the implied fair
      value of goodwill with the carrying amount of goodwill at the
      reporting unit, with the excess of the carrying amount over
      the fair value recognized as an impairment loss.
     
      Long-Lived
      Assets
     
      We
      review long-lived assets for impairment whenever events or
      changes in circumstances indicate that the carrying amount of
      an asset may not be recoverable in accordance with ASC
      360-10. Recoverability is measured by comparison of the
      carrying amount to the future net cash flows which the assets
      are expected to generate.  If such assets are
      considered to be impaired, the impairment to be recognized is
      measured by the amount by which the carrying amount of the
      assets exceeds the projected future cash flows arising from
      the asset determined by management to be commensurate with
      the risk inherent to our current business model.
     
      Income
      per Common Share
     
      The
      Company computes earnings per share under ASC 260-10,
      Earnings Per Share.  Basic net income per common share
      is computed by dividing net income by the weighted average
      number of outstanding shares of common stock.  Diluted
      earnings per share is computed using the weighted average
      number of common and common stock equivalent shares
      outstanding during the period. There is no effect on
      diluted income per share since the common stock equivalents
      are anti-dilutive. Dilutive common stock equivalents
      consist of shares issuable the exercise of the Company's
      outstanding stock options and warrants.
     
      Use
      of Estimates
     
      The
      preparation of financial statements in conformity with
      generally accepted accounting principles requires management
      to make estimates and assumptions that affect certain
      reported amounts and disclosures.  Accordingly,
      actual results could differ from those estimates.
     
      Income
      Taxes
     
      The
      Company accounts for income taxes in accordance with ASC
      740-10 “Income Taxes.” Under this method,
      deferred income taxes (when required) are provided based on
      the difference between the financial reporting and income tax
      bases of assets and liabilities and net operating losses at
      the statutory rates enacted for future periods. The Company
      has a policy of establishing a valuation allowance when it is
      more likely than not that the Company will not realize the
      benefits of its deferred tax assets in the future.
     
      The
      Company has adopted the Financial Accounting Standards Board
      (“FASB”) issued ASC 740-10-25, which prescribes a
      recognition threshold and measurement attribute for the
      financial statement recognition and measurement of a tax
      position taken or expected to be taken in a tax return. ASC
      740-10-25 also provides guidance on derecognition,
      classification, treatment of interest and penalties, and
      disclosure of such positions.
     
      Revenue
      Recognition
     
      For
      revenue from product sales, we recognize revenue in
      accordance with ASC 605-10, and ASC Topic 13 guidelines that
      require that four basic criteria must be met before revenue
      can be recognized: (1) persuasive evidence of an arrangement
      exists; (2) delivery has occurred; (3) the selling price is
      fixed and determinable; and (4) collectability is reasonably
      assured.  Determination of criteria (3) and (4) are
      based on management’s judgments regarding the fixed
      nature of the selling prices of the products delivered and
      the collectability of those amounts.  Provisions
      for discounts and rebates to customers, estimated returns and
      allowances, and other adjustments are provided for in the
      same period the related sales are recorded.  We
      defer any revenue for which the product has not been
      delivered or is subject to refund until such time that we and
      the customer jointly determine that the product has been
      delivered or no refund will be required.  The
      guidelines also address the accounting for arrangements that
      may involve the delivery or performance of multiple products,
      services and/or rights to use assets. For revenue
      attributable to recurring services, the Company recognizes
      revenue at the start of the service month for monthly support
      revenues and defers revenue for annual support services over
      the term of the service period.
     
      We
      provide call center support services to properties installed
      by us and also to properties installed by other providers. In
      addition, we provide the property with the portal to access
      the Internet. We receive monthly service fees from such
      properties for our services and Internet access. We recognize
      the service fee ratably over the term of the contract. The
      prices for these services are fixed and determinable prior to
      delivery of the service. The fair value of these services is
      known due to objective and reliable evidence from contracts
      and standalone sales. We report such revenues as recurring
      revenues.
     
      Stock
      Based Compensation
     
      We
      account for our stock based awards in accordance with ASC
      718-10, Compensation, which requires a fair value measurement
      and recognition of compensation expense for all share-based
      payment awards made to our employees and directors, including
      employee stock options and restricted stock awards. We
      estimate the fair value of stock options granted using the
      Black-Scholes valuation model. This model requires us to make
      estimates and assumptions including, among other things,
      estimates regarding the length of time an employee will
      retain vested stock options before exercising them, the
      estimated volatility of our common stock price and the number
      of options that will be forfeited prior to vesting. The fair
      value is then amortized on a straight-line basis over the
      requisite service periods of the awards, which is generally
      the vesting period. Changes in these estimates and
      assumptions can materially affect the determination of the
      fair value of stock-based compensation and consequently, the
      related amount recognized in our consolidated statements of
      operations.
     
      The
      expected term of the options represents the estimated period
      of time until exercise and is based on historical experience
      of similar awards, giving consideration to the contractual
      terms, vesting schedules and expectations of future employee
      behavior. For 2011 and prior years, expected stock price
      volatility is based on the historical volatility of the
      Company’s stock for the related vesting periods.
     
      Stock-based
      compensation expense in connection with options granted to
      employees for the three and six months ended June 30, 2011
      and 2010 was $7,994 and $15,988 and $46,780 and $88,181,
      respectively.
     
      Deferred
      Lease Liability
     
      Rent
      expense is recorded on a straight-line basis over the term of
      the lease. Rent escalations and rent abatement periods during
      the term of the lease create a deferred lease liability which
      represents the excess of cumulative rent expense recorded to
      date over the actual rent paid to date.
     
      Reclassifications
     
      Certain
      reclassifications have been made in prior year's financial
      statements to conform to classifications used in the current
      year.
