**REPORT
      OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING
      FIRM**











To
      the
      Board of Directors and Shareholder


MidAmerican
      Energy Company


Des
      Moines, Iowa





We
      have
      reviewed the accompanying consolidated balance sheet of MidAmerican Energy
      Company and subsidiary (the “Company”) as of June 30, 2006, and the related
      consolidated statements of operations for the three-month and six-month periods
      ended June 30, 2006 and 2005, and of cash flows for the six-month periods
      ended June 30, 2006 and 2005. These interim financial statements are the
      responsibility of the Company's management.





We
      conducted our reviews in accordance with the standards of the Public Company
      Accounting Oversight Board (United States). A review of interim financial
      information consists principally of applying analytical procedures and making
      inquiries of persons responsible for financial and accounting matters. It is
      substantially less in scope than an audit conducted in accordance with the
      standards of the Public Company Accounting Oversight Board (United States),
      the
      objective of which is the expression of an opinion regarding the financial
      statements taken as a whole. Accordingly, we do not express such an
      opinion.





Based
      on
      our reviews, we are not aware of any material modifications that should be
      made
      to such consolidated interim financial statements for them to be in conformity
      with accounting principles generally accepted in the United States of
      America.





We
      have
      previously audited, in accordance with the standards of the Public Company
      Accounting Oversight Board (United States), the consolidated balance sheet
      and
      statement of capitalization (not presented herein) of MidAmerican Energy Company
      and subsidiary as of December 31, 2005, and the related consolidated
      statements of operations, comprehensive income, retained earnings, and cash
      flows for the year then ended (not presented herein); and in our report dated
      March 3, 2006 (May 16, 2006 as to Note 10), we expressed an
      unqualified opinion on those consolidated financial statements. In our opinion,
      the information set forth in the accompanying consolidated balance sheet as
      of
      December 31, 2005 is fairly stated, in all material respects, in relation
      to the consolidated balance sheet from which it has been derived.

            **New
                Accounting Pronouncements**





In
      July
      2006, the Financial Accounting Standards Board (“FASB”) issued FASB
      Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - an
      interpretation of FASB Statement No. 109” ** (“FIN
      48”) *.* FIN 48 clarifies the accounting for uncertainty in income taxes recognized
      in accordance with Statement of Financial Accounting Standards No. 109,
“Accounting for Income Taxes,” and 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 return. Guidance is also
      provided on de-recognition, classification, interest and penalties, accounting
      in interim periods, disclosure and transition. FIN 48 is effective for fiscal
      years beginning after December 15, 2006. MidAmerican Funding and
      MidAmerican Energy are currently evaluating the impact of adopting FIN 48 on
      their respective consolidated financial positions and results of
      operations.

                and Contingencies**(a)
            Environmental
                Matters





MidAmerican
      Energy is subject to numerous environmental laws, including the federal Clean
      Air Act and various state air quality laws; the Endangered Species Act; the
      Comprehensive Environmental Response, Compensation and Liability Act and similar
      state laws relating to environmental cleanups; the Resource Conservation and
      Recovery Act and similar state laws relating to the storage and handling of
      hazardous materials; and the Clean Water Act and similar state laws relating
      to
      water quality. These laws have the potential for impacting MidAmerican Energy’s
      operations. Specifically, the Clean Air Act will likely continue to impact
      the
      operation of MidAmerican Energy’s generating facilities and will likely require
      MidAmerican Energy to reduce emissions from those facilities through the
      installation of additional or improved emission controls, purchase additional
      emission allowances, or implement some combination thereof.

Air
      Quality -





MidAmerican
      Energy is subject to applicable provisions of the Clean Air Act and related
      air
      quality standards promulgated by the United States Environmental Protection
      Agency (“EPA”). The Clean Air Act provides the framework for regulation of
      certain air emissions and permitting and monitoring associated with those
      emissions. MidAmerican Energy believes it is in material compliance with current
      air quality requirements.





The
      EPA
      has in recent years implemented more stringent national ambient air quality
      standards for ozone and new standards for fine particulate matter. These
      standards set the minimum level of air quality that must be met throughout
      the
      United States. Areas that achieve the standards, as determined by ambient air
      quality monitoring, are characterized as being in attainment of the standard.
      Areas that fail to meet the standard are designated as being nonattainment
      areas. Generally, once an area has been designated as a nonattainment area,
      sources of emissions that contribute to the failure to achieve the ambient
      air
      quality standards are required to make emissions reductions. The EPA has
      concluded that the entire state of Iowa, where MidAmerican Energy’s major
      emission sources are located, is in attainment of the ozone, and the current
      fine particulate matter, standards.





In
      December 2005, the EPA proposed a revision of the ambient air quality
      standards for fine particles that would maintain the current annual standard
      and
      set a new, more stringent 24-hour standard for the concentration of fine
      particulate in ambient air. The EPA is scheduled to issue final rules in
      September 2006.





In
      March 2005, the EPA released the final Clean Air Mercury Rule (“CAMR”). The
      CAMR utilizes a market-based cap and trade mechanism to reduce mercury emissions
      from coal-burning power plants from the 1999 nationwide level of 48 tons to
      15
      tons at full implementation. The CAMR’s two-phase reduction program requires
      initial reductions of mercury emission in 2010 and an overall reduction in
      mercury emissions from coal-burning power plants of 70% by 2018. Individual
      states are required to implement the CAMR or alternative requirements to achieve
      equivalent or greater mercury emission reductions through their state
      implementation plans.





In
      March 2005, the EPA released the final Clean Air Interstate Rule (“CAIR”),
      calling for reductions of sulfur dioxide (“SO 2 ”)
      and
      nitrogen oxides (“NO x ”)
      emissions in the eastern United States through, at each state’s option, a
      market-based cap and trade system, emission reductions, or both. The state
      of
      Iowa has implemented rules that exercise the option of the market-based cap
      and
      trade system. While the state of Iowa has been determined to be in attainment
      of
      the ozone and fine particulate standards, Iowa has been found to significantly
      contribute to nonattainment of the fine particulate standard in Cook County,
      Illinois; Lake County, Indiana; Madison County, Illinois; St. Clair County,
      Illinois; and Marion County, Indiana. The EPA has also concluded that emissions
      from Iowa significantly contribute to ozone nonattainment in Kenosha and
      Sheboygan counties in Wisconsin and Macomb County, Michigan. Under the final
      CAIR, the first phase reductions of SO 2 emissions are effective on January 1, 2010, with the second phase
      reductions effective January 1, 2015. For NO x ,
      the
      first phase emissions reductions are effective January 1, 2009, and
      the second phase reductions are effective January 1, 2015. The CAIR calls
      for overall reductions of SO 2 and
      NO x in Iowa
      of 68% and 67%, respectively, from 2003 levels by 2015.





The
      CAMR
      or the CAIR could, in whole or in part, be superseded or made more stringent
      by
      one of a number of multi-pollutant emission reduction proposals currently under
      consideration at the federal level, including pending legislative proposals
      that
      contemplate 70% to 90% reductions of SO 2 ,
      NO X and
      mercury, as well as possible new federal regulation of carbon dioxide and other
      gases that may affect global climate change. In addition to any federal
      legislation that could be enacted by Congress to supersede the CAMR and the
      CAIR, the rules could be changed or overturned as a result of litigation. The
      sufficiency of the standards established by both the CAMR and the CAIR has
      been
      legally challenged in the United States District Court for the District of
      Columbia.





The
      EPA
      has initiated a regional haze program intended to improve visibility at specific
      federally protected areas. Some of MidAmerican Energy’s plants meet the
      threshold applicability criteria under the Clean Air Visibility Rules.
      MidAmerican Energy and other stakeholders are participating in the Central
      States Regional Air Partnership to help develop the technical and policy tools
      needed to comply with this program.




11




MidAmerican
      Energy has implemented a planning process that forecasts the site-specific
      controls and actions that may be required to meet emissions reductions as
      promulgated by the EPA. In accordance with an Iowa law passed in 2001,
      MidAmerican Energy has on file with the Iowa Utilities Board (“IUB”) its current
      multi-year plan and budget for managing SO 2 ,
      NO X and
      mercury from its generating facilities in a cost-effective manner. The plan,
      which is required to be updated every two years, provides specific actions
      to be
      taken at each coal-fired generating facility and the related costs and timing
      for each action. Pursuant to an unrelated rate settlement agreement approved
      by
      the IUB on October 17, 2003, if prior to January 1, 2011, capital
      and operating expenditures to comply with air quality requirements cumulatively
      exceed $325 million, then MidAmerican Energy may seek to recover the
      additional expenditures from customers.





Under
      the
      existing New Source Review (“NSR”) provisions of the Clean Air Act, any facility
      that emits regulated pollutants is required to obtain a permit from the EPA
      or a
      state regulatory agency prior to (1) beginning construction of a new major
      stationary source of an NSR-regulated pollutant or (2) making a physical or
      operational change to an existing stationary source of such pollutants that
      increases certain levels of emissions, unless the changes are exempt under
      the
      regulations (including routine maintenance, repair and replacement of
      equipment). In general, projects subject to NSR regulations are subject to
      pre-construction review and permitting under the Prevention of Significant
      Deterioration (“PSD”) provisions of the Clean Air Act. Under the PSD program, a
      project that emits threshold levels of regulated pollutants must undergo a
      Best
      Available Control Technology analysis and evaluate the most effective emissions
      controls. These controls must be installed in order to receive a permit.
      Violations of NSR regulations, which may be alleged by the EPA, states, and
      environmental groups, among others, potentially subject a utility to material
      expenses for fines and other sanctions and remedies including requiring
      installation of enhanced pollution controls and funding supplemental
      environmental projects.





The
      EPA
      has requested from several utilities information and supporting documentation
      regarding their capital projects for various generating plants. The requests
      were issued as part of an industry-wide investigation to assess compliance
      with
      the NSR and the New Source Performance Standards of the Clean Air Act. In
      December 2002 and April 2003, MidAmerican Energy received requests
      from the EPA to provide documentation related to its capital projects from
      January 1, 1980, to April 2003 for a number of its generating plants.
      MidAmerican Energy has submitted information to the EPA in responses to these
      requests, and there are currently no outstanding data requests pending from
      the
      EPA. MidAmerican Energy cannot predict the outcome of these requests at this
      time.





In
      2002
      and 2003, the EPA proposed various changes to its NSR rules that clarify what
      constitutes routine repair, maintenance and replacement for purposes of
      triggering NSR requirements. These changes have been subject to legal challenge
      and, until such time as the legal challenges are resolved and the rules are
      effective, MidAmerican Energy will continue to manage projects at its generating
      plants in accordance with the rules in effect prior to 2002. In
      October 2005, the EPA proposed a rule that would change or clarify how
      emission increases are to be calculated for purposes of determining the
      applicability of the NSR permitting program for existing power plants.





In
      February 2005, the Kyoto Protocol became effective, requiring 35 developed
      countries to reduce greenhouse gas emissions by approximately 5% between 2008
      and 2012. While the United States did not ratify the protocol, the ratification
      and implementation of its requirements in other countries has resulted in
      increased attention on the climate change issue in the United States. In 2005,
      the Senate adopted a “sense of the Senate” resolution that puts the Senate on
      record that Congress should enact a comprehensive and effective national program
      of mandatory, market-based limits and incentives on emissions of greenhouse
      gases that slow, stop, and reverse the growth of such emissions at a rate and
      in
      a manner that will not significantly harm the United States economy; and will
      encourage comparable action by other nations that are major trading partners
      and
      key contributors to global emissions. It is anticipated that the resolution
      may
      be further addressed by Congress in 2006. While debate continues at the national
      level over the direction of domestic climate policy, several states are
      developing state-specific or regional legislative initiatives to reduce
      greenhouse gas emissions. In December 2005, the states of Connecticut,
      Delaware, Maine, New Hampshire, New Jersey, New York and Vermont signed a
      mandatory regional pact to reduce greenhouse gas emissions that would become
      effective in 2009 and ultimately would require a reduction in greenhouse gas
      emissions of 10 percent from 1990 levels. An executive order signed by
      California’s governor in June 2005 would reduce greenhouse gas emissions in
      that state to 2000 levels by 2010, to 1990 levels by 2020 and 80 percent below
      1990 levels by 2050. In addition, California is seeking to apply a greenhouse
      gas emission performance standard to all electricity generated within the state
      or delivered from outside the state that is no higher than the greenhouse gas
      emission levels of a state-of-the-art combined-cycle natural gas generation
      facility.

Litigation
      was filed in the federal district court for the southern district of New York
      seeking to require reductions of carbon dioxide emissions from generating
      facilities of five large electric utilities. The court dismissed the public
      nuisance suit, holding that such critical issues affecting the United States
      such as greenhouse gas emissions reductions are not the domain of the court
      and
      should be resolved by the Executive Branch and the U.S. Congress. This ruling
      has been appealed to the Second Circuit Court of Appeals. The outcome of climate
      change litigation and federal and state initiatives cannot be determined at
      this
      time; however, adoption of stringent limits on greenhouse gas emissions could
      significantly impact MidAmerican Energy’s fossil-fueled facilities and,
      therefore, its results of operations.





The
      EPA’s
      regulation of certain pollutants under the Clean Air Act, and its failure to
      regulate other pollutants, is being challenged by various lawsuits brought
      by
      both individual state attorney generals and environmental groups. To the extent
      that these actions may be successful in imposing additional and/or more
      stringent regulation of emissions on fossil-fueled facilities in general and
      MidAmerican Energy’s facilities in particular, such actions will likely impact
      MidAmerican Energy’s fossil-fueled facilities and, therefore, its results of
      operations.





(b)
            Nuclear
                Decommissioning Costs





Expected
      nuclear decommissioning costs for Quad Cities Station have been developed based
      on a site-specific decommissioning study that includes decontamination,
      dismantling, site restoration, dry fuel storage cost and an assumed shutdown
      date. Quad Cities Station nuclear decommissioning costs are included in base
      rates in MidAmerican Energy’s Iowa tariffs.





MidAmerican
      Energy’s share of estimated decommissioning costs for Quad Cities Station, as
      calculated in accordance with Statement of Financial Accounting Standards No.
      143, “Accounting for Asset Retirement Obligations,” was $167.7 million and
      $163.0 million as of June 30, 2006 and December 31, 2005,
      respectively, and is reflected in Asset Retirement Obligations on the
      Consolidated Balance Sheets. Refer to Note (14) of MidAmerican Energy’s most
      recently filed Form 10-K for a discussion of asset retirement obligations.
      MidAmerican Energy has established trusts for the investment of funds for
      decommissioning the Quad Cities Station. The fair value of the assets held
      in
      the trusts as of June 30, 2006 and December 31, 2005, was
      $234.6 million and $228.1 million, respectively, and is reflected in
      Investments and Nonregulated Property, Net on the Consolidated Balance
      Sheets.





MidAmerican
      Energy’s depreciation and amortization includes costs for Quad Cities Station
      decommissioning. The regulatory provision charged to expense is equal to the
      funding that is being collected in Iowa rates.





(c)
            Deferred
                Construction Costs





On
      February 12, 2003, MidAmerican Energy executed a contract with Mitsui &
Co. Energy Development, Inc. (“Mitsui”) for engineering, procurement and
      construction of a 790-MW (based on expected accreditation) coal-fired generating
      plant expected to be completed in the summer of 2007. MidAmerican Energy
      currently holds a 60.67% individual ownership interest as a tenant in common
      with the other owners of the plant. Under the contract, MidAmerican Energy
      is
      allowed to defer payments, including the other owners’ shares, for up to
      $200.0 million of billed construction costs through the end of the project.
      In July 2005, MidAmerican Energy reached the total allowed amount of
      $200.0 million of deferred payments. On the Consolidated Balance Sheets,
      the $200.0 million liability is reflected in Accounts Payable as of
      June 30, 2006, in anticipation of its payment in the summer of 2007 and in
      Other Liabilities - Other as of December 31, 2005.

      representing the other owners’ share of the deferred payments totaled
      $78.7 million as of June 30, 2006, and December 31, 2005,
      respectively, and is reflected on the Consolidated Balance Sheets in Other
      Current Assets as of June 30, 2006, and in Other Assets as of
      December 31, 2005. MidAmerican Energy will bill each of the other owners
      for its share of the deferred payments when payment is made to
      Mitsui.

                Matters**





Under
      a
      series of settlement agreements between MidAmerican Energy, the OCA and other
      intervenors approved by the IUB, MidAmerican Energy has agreed not to seek
      a
      general increase in electric base rates to become effective prior to
      January 1, 2013, unless its Iowa jurisdictional electric return on equity
      for any year falls below 10%. Prior to filing for a general increase in electric
      rates, MidAmerican Energy is required to conduct 30 days of good faith
      negotiations with the signatories to the settlement agreements to attempt to
      avoid a general increase in such rates. As a party to the settlement agreements,
      the OCA has agreed not to request or support any decrease in MidAmerican
      Energy’s Iowa electric base rates to become effective prior to January 1,
      2013. The settlement agreements specifically allow the IUB to approve or order
      electric rate design or cost of service rate changes that could result in
      changes to rates for specific customers as long as such changes do not result
      in
      an overall increase in revenues for MidAmerican Energy. The settlement
      agreements also each provide that portions of revenues associated with Iowa
      retail electric returns on equity within specified ranges will be recorded
      as a
      regulatory liability.





Under
      a
      settlement agreement approved by the IUB on December 21, 2001, which was
      effective through December 31, 2005, an amount equal to 50% of revenues
      associated with returns on equity between 12% and 14%, and 83.33% of revenues
      associated with returns on equity above 14%, in each year was recorded as a
      regulatory liability. A settlement agreement, which was filed in conjunction
      with MidAmerican Energy’s application for ratemaking principles on its 2004/2005
      wind-powered generation project and approved by the IUB on October 17,
      2003, provides that during the period January 1, 2006 through
      December 31, 2010, an amount equal to 40% of revenues associated with
      returns on equity between 11.75% and 13%, 50% of revenues associated with
      returns on equity between 13% and 14%, and 83.3% of revenues associated with
      returns on equity above 14%, in each year will be recorded as a regulatory
      liability. The settlement agreement also includes commitments by MidAmerican
      Energy and the OCA not to seek or support a general increase or decrease,
      respectively, in electric base rates to become effective prior to
      January 1, 2011.





On
      January 31, 2005, the IUB approved a settlement agreement filed in
      conjunction with MidAmerican Energy’s 2005 expansion of its wind-powered
      generation project. On April 18, 2006, the IUB approved a settlement
      agreement filed in conjunction with MidAmerican Energy’s application for up to
      545 MW, based on nameplate ratings, of additional wind-powered generation
      capacity in Iowa. The settlement agreements extend the current revenue sharing
      mechanism through 2011 and 2012, respectively, and extend MidAmerican Energy’s
      and the OCA’s commitments regarding general increases or decreases in electric
      base rates through December 31, 2011 and 2012, respectively.





The
      regulatory liabilities created by the settlement agreements are recorded as
      a
      regulatory charge in depreciation and amortization expense when the liability
      is
      accrued. Additionally, interest expense is accrued on the portion of the
      regulatory liability balance recorded in prior years. Regulatory liabilities
      created for the years through 2010 will be reduced as they are credited against
      plant in service associated with generating plant additions. As a result of
      such
      credits applied to generating plant balances, future depreciation will be
      reduced. The regulatory liability accrued for 2011 and 2012, if any, will be
      credited to customer bills in 2012 and 2013, respectively. The change in the
      balance of the regulatory liability is summarized as follows (in
      thousands):

MidAmerican
      Energy expects to contribute $5.9 million and $15.6 million in 2006 to
      its pension and postretirement plans, respectively. As of
      June 30, 2006, $3.0 million and $6.7 million of

            **Segment
                Information**




Beginning
      in 2006, MidAmerican Energy changed its reportable operating segments. Prior
      year amounts are reflected on a consistent basis with the 2006 amounts.
      MidAmerican Energy has identified two reportable operating segments: regulated
      electric and regulated gas. The regulated electric segment derives most of
      its
      revenue from regulated retail sales of electricity to residential, commercial,
      and industrial customers and from wholesale sales to other utilities. The
      regulated gas segment derives most of its revenue from regulated retail sales
      of
      natural gas to residential, commercial, and industrial customers and also
      obtains significant revenues by transporting gas owned by others through its
      distribution system. Pricing for regulated electric and gas sales are
      established separately by regulatory agencies; therefore, management also
      reviews each segment separately to make decisions regarding allocation of
      resources and in evaluating performance. Common operating costs, interest
      income, interest expense and income tax expense are allocated to each segment
      based on MidAmerican Energy allocators most related to the nature of the cost.
      “Nonregulated and other” in the tables below consists principally of
      nonregulated gas, nonregulated electric and parent company
      activities.

                Management**





In
      2006,
      MidAmerican Energy changed its management strategy with regard to certain
      nonregulated end-use gas contracts. This change resulted in recording
      prospectively the related revenues and cost of sales on a gross, rather than
      net, basis in accordance with Emerging Issues Task Force Issue No. 02-3,
“Recognition and Reporting of Gains and Losses on Energy Trading Contracts Under
      Issues No. 98-10 and 00-17.”

**REPORT
      OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING
      FIRM**











To
      the
      Board of Managers and Member


MidAmerican
      Funding, LLC


Des
      Moines, Iowa





We
      have
      reviewed the accompanying consolidated balance sheet of MidAmerican Funding,
      LLC
      and subsidiaries (the “Company”) as of June 30, 2006, and the related
      consolidated statements of operations for the three-month and six-month periods
      ended June 30, 2006 and 2005, and of cash flows for the six-month periods
      ended June 30, 2006 and 2005. These interim financial statements are the
      responsibility of the Company’s management.





We
      conducted our reviews in accordance with the standards of the Public Company
      Accounting Oversight Board (United States). A review of interim financial
      information consists principally of applying analytical procedures and making
      inquiries of persons responsible for financial and accounting matters. It is
      substantially less in scope than an audit conducted in accordance with the
      standards of the Public Company Accounting Oversight Board (United States),
      the
      objective of which is the expression of an opinion regarding the financial
      statements taken as a whole. Accordingly, we do not express such an opinion.





Based
      on
      our reviews, we are not aware of any material modifications that should be
      made
      to such consolidated interim financial statements for them to be in conformity
      with accounting principles generally accepted in the United States of
      America.





We
      have
      previously audited, in accordance with the standards of the Public Company
      Accounting Oversight Board (United States), the consolidated balance sheet
      and
      statement of capitalization (not presented herein) of MidAmerican Funding,
      LLC
      and subsidiaries as of December 31, 2005, and the related consolidated
      statements of operations, comprehensive income, retained earnings, and cash
      flows for the year then ended (not presented herein); and in our report dated
      March 3, 2006 (May 16, 2006 as to Notes 1(m) and 10), we
      expressed an unqualified opinion on those consolidated financial statements.
      In
      our opinion, the information set forth in the accompanying consolidated balance
      sheet as of December 31, 2005 is fairly stated, in all material respects,
      in relation to the consolidated balance sheet from which it has been
      derived.

**NOTES
      TO CONSOLIDATED FINANCIAL
      STATEMENTS**


**(Unaudited)**





**1.**
            **General**





The
      consolidated financial statements included herein have been prepared by
      MidAmerican Funding, LLC (“MidAmerican Funding”), without audit, pursuant to the
      rules and regulations of the Securities and Exchange Commission. Certain
      information and disclosures normally included in a complete set of financial
      statements prepared in accordance with generally accepted accounting principles
      have been condensed or omitted pursuant to such rules and regulations. In the
      opinion of MidAmerican Funding, all adjustments, consisting of normal recurring
      adjustments, have been made to present fairly its financial position, results
      of
      operations and changes in cash flows for the periods presented. Where
      applicable, prior year amounts have been reclassified to a basis consistent
      with
      the current year presentation. Such reclassifications did not impact previously
      reported net income or retained earnings. All significant intercompany
      transactions have been eliminated. Although MidAmerican Funding believes that
      the disclosures contained herein are adequate to make the information presented
      not misleading, it is suggested that these financial statements be read in
      conjunction with the consolidated financial statements and the notes thereto
      included in MidAmerican Funding’s latest Annual Report on Form
      10-K.





Certain
      classifications of amounts for 2005 are different than originally reported.

      June 30, 2005, now reflects Purchases of Available-for-Sale Securities
      totaling $41.1 million and Proceeds from Sales of Available-for-Sale
      Securities totaling $35.6 million related to transactions of securities
      held in the Quad Cities Station nuclear decommissioning trusts.

**6.**
            **Segment
                Information**





Beginning
      in 2006, MidAmerican Funding changed its reportable operating segments. Prior
      year amounts are reflected on a consistent basis with the 2006 amounts.
      MidAmerican Funding has identified two reportable operating segments: regulated
      electric and regulated gas. The regulated electric segment derives most of
      its
      revenue from regulated retail sales of electricity to residential, commercial,
      and industrial customers and from wholesale sales to other utilities. The
      regulated gas segment derives most of its revenue from regulated retail sales
      of
      natural gas to residential, commercial, and industrial customers and also
      obtains significant revenues by transporting gas owned by others through its
      distribution system. Pricing for regulated electric and gas sales are
      established separately by regulatory agencies; therefore, management also
      reviews each segment separately to make decisions regarding allocation of
      resources and in evaluating performance. Common operating costs, interest
      income, interest expense and income tax expense are allocated to each segment
      based on MidAmerican Funding allocators most related to the nature of the cost.
      “Nonregulated and other” in the tables below consists principally of
      nonregulated gas, nonregulated electric and parent company
      activities.





The
      following tables provide MidAmerican Funding’s operating revenues, net income
      and total assets on a reportable operating segment basis (in
      thousands):

**8.**
            **Goodwill**





In
      January 2006, MidAmerican Energy changed its reportable operating segments.
      Accordingly, goodwill has been reclassified to match the new segment
      presentation. For the six months ended June 30, 2006, MidAmerican Funding
      adjusted goodwill for a change in deferred income taxes due to tax matters
      existing at the time of its purchase of MHC. The following table shows the
      change in the carrying amount of goodwill by reportable operating segment for
      the six months ended June 30, 2006 (in thousands):

            **Other
                Income and Other Expense**





During
      the second quarter of 2006, MidAmerican Funding sold a majority of the common
      shares it held of an electronic energy and metals trading exchange and recorded
      proceeds of $27.6 million and pre-tax gains totaling $27.6 million, or
      $16.5 million after-tax. MidAmerican Funding donated its remaining shares
      in the company to a charitable foundation and recognized $4.5 million of
      both pre-tax gain and donation expense. MidAmerican Funding’s equity investment
      in the company was carried at a cost of zero and was obtained as a result of
      MidAmerican Funding’s sale of a predecessor company in 1997. In 2001,
      MidAmerican Funding received common shares for its ownership interest in the
      company. The shares were restricted from sale until the second quarter of 2006,
      at which time they became unrestricted in conjunction with an initial public
      offering, the timing of which was previously unknown. Accordingly, prior to
      the
      second quarter of 2006, the shares had no readily determinable fair value and
      were not marked to market, resulting in no other comprehensive income being
      recorded prior to that time.

**Executive
      Summary**





MidAmerican
      Energy’s earnings on common stock improved $13.4 million to
      $45.3 million for the second quarter of 2006 compared to $31.9 million
      for the second quarter of 2005. MidAmerican Funding’s net income increased
      $32.3 million to $57.5 million for the second quarter of 2006 compared
      to $25.2 million for the second quarter of 2005.





MidAmerican
      Energy’s earnings on common stock improved $44.0 million to
      $131.9 million for the first six months of 2006 compared to
      $87.9 million for the first six months of 2005. MidAmerican Funding’s net
      income increased $62.5 million to $144.1 million for the first six
      months of 2006 compared to $81.6 million for the first six months of 2005.





The
      following significant events and changes, as discussed in more detail herein,
      highlight some of the factors that had an effect on MidAmerican Energy’s and
      MidAmerican Funding’s operating results, liquidity and capital resources during
      the periods presented:

·
            MidAmerican
                Energy is currently constructing a 790-megawatt (“MW”) (expected
                accreditation) super-critical-temperature, coal-fired generation
                project
                and expects to invest approximately $737 million in the project
                through 2007. Through June 30, 2006, $594.0 million had
                been invested, including $121.3 million for MidAmerican Energy’s
                share of deferred payments allowed by contract.





·
            In
                the last half of 2005, MidAmerican Energy placed 200 MW (nameplate
                ratings) of wind-powered generation into service. On April 18, 2006,
                MidAmerican Energy received Iowa Utilities Board (“IUB”) approval of the
                ratemaking principles for up to 545 MW (nameplate ratings) of additional
                wind-powered generation capacity in Iowa. MidAmerican Energy has
                entered
                into agreements with wind project developers and contractors to add
                99 MW
                and 123 MW (nameplate ratings) of wind-powered generation by the
                end of
                2006 and 2007, respectively.





·
            MidAmerican
                Energy’s regulated electric gross margin improved $46.9 million due
                principally to an increase in gross margin for electric wholesale
                sales
                compared to the second quarter of 2005 driven by higher market prices
                and
                increased sales volumes.





·
            The
                regulatory expense related to the Iowa revenue sharing arrangement
                increased by $12.0 million compared to the second quarter of 2005.
                Amounts under the arrangement are determined based upon Iowa electric
                returns on equity which were favorably impacted by the higher wholesale
                margins in the second quarter of 2006. Iowa revenue sharing is recorded
                as
                depreciation and amortization in the accompanying consolidated statement
                of operations.





·
            During
                the second quarter of 2006, MidAmerican Funding recognized pre-tax
                gains
                of $27.6 million, or $16.5 million after-tax, on the sales of
                its shares of common stock of an electronic energy and metals trading
                exchange.





Following
      is a discussion of various factors that affected earnings for the periods
      presented on the Consolidated Statements of Operations. Explanations include
      management's best estimate of the impact of weather, customer growth and other
      factors.

Electric
      gross margin for the second quarter of 2006 increased $46.9 million
      compared to the second quarter of 2005 due to a $30.6 million increase in
      gross margin on wholesale sales due primarily to a higher margin per megawatt
      hour sold. Gross margin on retail sales increased $12.0 million due
      principally to customer growth. Additionally, transmission revenues increased
      $4.0 million due to the increase in wholesale sales volumes.

Sales
      of
      energy to other utilities, municipalities and marketers inside and outside
      of
      MidAmerican Energy's delivery system are classified as wholesale. An increase
      in
      the average electric wholesale margins per megawatt hour sold due to higher
      market prices and a greater availability of MidAmerican Energy-owned base load
      generation improved electric wholesale gross margin by $22.3 million
      compared to the second quarter of 2005. The increased availability of
      MidAmerican Energy-owned base load generation, including generation
      available as a result of newly added wind generation supplying retail customers,
      as well as market opportunities, contributed to a 57.9% increase in
      wholesale sales volumes during the second quarter of 2006, resulting in an
      $8.3 million increase in wholesale gross margin.





Gross
      margin on electric retail sales increased $12.0 million, with electric
      retail sales volumes increasing 6.1% compared to the second quarter of 2005.
      An
      increase in the average number of retail customers, in particular the addition
      of a large steel manufacturer in the fourth quarter of 2005, improved electric
      retail gross margin by $9.1 million compared to the second quarter of 2005.
      Electricity usage factors not dependent on weather, such as changes in
      individual customer usage patterns, increased electric margin by
      $6.0 million. The effect of temperature conditions during the second
      quarter of 2006 compared to the second quarter of 2005 resulted in a
      $1.9 million decrease in electric retail gross margin. An increase in fuel
      costs related to Iowa retail electric sales decreased electric retail gross
      margin by $2.3 million compared to the second quarter of 2005 due in part
      to an increase in the portion of energy requirements met with higher cost fuel.
      Recoveries of energy efficiency program costs increased electric retail gross
      margin by $1.2 million compared to the second quarter of 2005. Changes in
      revenues from the recovery of energy efficiency program costs are substantially
      matched with corresponding changes in other operating expenses.

      gas revenues include purchased gas adjustment clauses through which MidAmerican
      Energy is allowed to recover the cost of gas sold from its retail gas utility
      customers. Consequently, fluctuations in the cost of gas sold do not affect
      gross margin or net income because revenues reflect comparable fluctuations
      through the purchased gas adjustment clauses. For the second quarter of 2006,
      $32.2 million of the decrease in cost of gas sold and gas revenues was due
      to
      the decrease in sales volumes. Additionally, compared to the second quarter
      of
      2005, MidAmerican Energy’s average per-unit cost of gas sold decreased 6.7%,
      resulting in a $9.1 million decrease in cost of gas sold and revenues for
      the second quarter of 2006.

Other
      gas
      usage factors, such as changes in individual customer usage patterns and
      reaction to the increase in natural gas prices, decreased gas margin. The
      decrease in gas gross margin due to weather was the result of mild temperature
      conditions in the second quarter of 2006 compared to the same quarter in 2005.
      MidAmerican Energy's average number of gas retail customers increased 1.4%
      compared to the second quarter of 2005. Changes in revenues from the recovery
      of
      energy efficiency program costs are substantially matched with corresponding
      changes in other operating expenses.





Regulated
      Operating Expenses





Other
      operating expenses increased $8.6 million for the second quarter of 2006
      compared to the second quarter of 2005 due to a $6.6 million increase in
      transmission expense related to the increase in purchased power and electric
      wholesale sales. Energy efficiency program costs increased $2.3 million.
      Changes in energy efficiency program costs are substantially matched by changes
      in related electric and gas revenues.





Maintenance
      expenses for the second quarter of 2006 decreased $0.4 million compared to
      the second quarter of 2005. Steam generating plant maintenance decreased $4.0
      million as a result of planned outages in 2005 but was mostly offset by an
      increase in generation maintenance related to wind power facilities and an
      increase in distribution maintenance.





Depreciation
      and amortization expense for the second quarter of 2006 increased
      $13.1 million compared to the second quarter of 2005 due to a
      $12.0 million increase in regulatory expense related to a revenue sharing
      arrangement in Iowa as a result of higher Iowa electric returns on equity
      primarily from improved electric margins. Additionally, utility plant
      depreciation increased due primarily to wind power facilities placed in service
      in the third quarter of 2005. Refer to the “Utility Regulatory Matters” section
      for an explanation of the revenue sharing arrangement.

            8.4





Nonregulated
      revenues and cost of sales for the second quarter of 2006 increased due
      primarily to a change in the management strategy related to certain end-use
      gas
      contracts that resulted in recording prospectively the related revenues and
      cost
      of sales on a gross, rather than net, basis in accordance with Emerging Issues
      Task Force Issue No. 02-3, “Recognition and Reporting of Gains and Losses on
      Energy Trading Contracts Under Issues No. 98-10 and 00-17.” The decrease in
      nonregulated gross margin compared to the second quarter of 2005 was principally
      due to a decrease in nonregulated electric margins compared to the second
      quarter of 2005.





Allowance
      for Equity Funds





As
      a
      regulated public utility, MidAmerican Energy is allowed to capitalize, and
      record as income, a cost of construction for equity funds used, based on
      guidelines set forth by the Federal Energy Regulatory Commission (“FERC”). The
      $2.5 million increase in income for the capitalized allowance on equity
      funds used during construction in the second quarter of 2006 was due to the
      increase in construction work in progress compared to the second quarter of
      2005. MidAmerican Energy expects to continue to record higher-than-normal income
      for the allowance on equity funds used during construction through 2007 while
      the announced generating facilities are constructed.





Other
      Income and Expense





MidAmerican
      Funding -





Other
      income for the second quarter of 2006 includes $27.6 million of pre-tax
      gains from the sales of MidAmerican Funding’s shares of common stock of an
      electronic energy and metals trading exchange. Additionally, a $4.5 million
      gain was recognized on shares of that common stock, which MidAmerican Funding
      donated to a charitable foundation. Other expense for the second quarter of
      2006
      reflects $4.5 million of expense for the donation of the shares. Refer to
      Note (9) of MidAmerican Funding’s Notes to Consolidated Financial Statements for
      further discussion of these transactions.





Fixed
      Charges





The
      $3.4 million increase in interest on long-term debt was due to the effect
      of $300.0 million of MidAmerican Energy long-term debt issued on
      November 1, 2005, offset partially by maturities of higher rate debt
      in 2005. Other interest expense increased due to a higher balance of the Iowa
      revenue sharing liability. MidAmerican Energy is allowed to capitalize, and
      record as a reduction to fixed charges, a cost of construction for debt funds
      used, based on guidelines set forth by the FERC. The $1.4 million increase
      in
      allowance for borrowed funds for the second quarter of 2006 was due to the
      increase in construction work in progress compared to the second quarter of
      2005. MidAmerican Energy expects to continue to record higher-than-normal
      allowance for borrowed funds used during construction through 2007 while the
      announced generating facilities are constructed.

Income
      Taxes





MidAmerican
      Energy -





Federal
      law currently provides for federal production tax credits for energy produced
      by
      renewable electricity generation projects, including wind power facilities.
      MidAmerican Energy’s income taxes for the second quarter of 2006 were reduced
      $2.9 million more by the production tax credits compared to the second
      quarter of 2005 due to wind power facilities placed in service in the third
      quarter of 2005.





State
      utility rate regulation in Iowa requires that the tax effect of certain timing
      differences be flowed through immediately to customers. Therefore, amounts
      that
      would otherwise have been recognized in income tax expense have been included
      as
      changes in regulatory assets. This flow-through treatment of such timing
      differences impacts the effective tax rates from year to year.

Electric
      gross margin for the first six months of 2006 increased $102.7 million
      compared to the first six months of 2005 due to a $71.7 million increase in
      gross margin on wholesale sales due primarily to a higher margin per megawatt
      hour sold. Gross margin on retail sales increased $21.8 million due
      principally to customer growth. Additionally, transmission revenues increased
      $8.1 million due to the increase in wholesale sales volumes.





Sales
      of
      energy to other utilities, municipalities and marketers inside and outside
      of
      MidAmerican Energy's delivery system are classified as wholesale. An increase
      in
      the average electric wholesale margins per megawatt hour sold due to higher
      market prices and a greater availability of MidAmerican Energy-owned base load
      generation improved electric wholesale gross margin by $58.7 million
      compared to the first six months of 2005. The increased availability of
      MidAmerican Energy-owned base load generation, including generation available
      as
      a result of newly added wind generation supplying retail customers, as well
      as
      market opportunities, contributed to a 52.3% increase in wholesale sales
      volumes during the first six months of 2006, resulting in a $13.0 million
      increase in wholesale gross margin.





Gross
      margin on electric retail sales increased $21.8 million, with electric
      retail sales volumes increasing 7.3% compared to the first six months of 2005.
      An increase in the average number of retail customers, in particular the
      addition of a large steel manufacturer in the fourth quarter of 2005, improved
      electric retail gross margin by $17.7 million compared to the first six
      months of 2005. Electricity usage factors not dependent on weather, such as
      changes in individual customer usage patterns, increased electric margin by
      $12.1 million. The effect of temperature conditions during the first six
      months of 2006 compared to the first six months of 2005 resulted in a
      $4.4 million decrease in electric retail gross margin. An increase in fuel
      costs related to Iowa retail electric sales decreased electric retail gross
      margin by $5.2 million compared to the first six months of 2005 due in part
      to an increase in the portion of energy requirements met with higher cost fuel.
      Recoveries of energy efficiency program costs increased electric retail gross
      margin by $1.6 million compared to the first six months of 2005. Changes in
      revenues from the recovery of energy efficiency program costs are substantially
      matched with corresponding changes in other operating expenses.

      gas revenues include purchased gas adjustment clauses through which MidAmerican
      Energy is allowed to recover the cost of gas sold from its retail gas utility
      customers. Consequently, fluctuations in the cost of gas sold do not affect
      gross margin or net income because revenues reflect comparable fluctuations
      through the purchased gas adjustment clauses. Compared to the first six months
      of 2005, MidAmerican Energy’s average per-unit cost of gas sold increased 9.7%,
      resulting in a $44.5 million increase in cost of gas sold for the first six
      months of 2006. The increase in cost of gas sold and gas revenues as a result
      of
      the per-unit cost of gas sold was more than offset by a $92.9 million
      decrease due to the reduction in sales volumes.





The
      following table summarizes the variance in gas operating revenues based on
      the
      change in gas cost recoveries and margin components.

Other
      gas
      usage factors, such as changes in individual customer usage patterns and
      reaction to the increase in natural gas prices, decreased gas margin. The
      decrease in gas gross margin due to weather was the result of mild temperature
      conditions in the first six months of 2006 compared to the same quarter in
      2005.
      MidAmerican Energy's average number of gas retail customers increased 1.2%
      compared to the first six months of 2005. Changes in revenues from the recovery
      of energy efficiency program costs are substantially matched with corresponding
      changes in other operating expenses.





Regulated
      Operating Expenses





Other
      operating expenses increased $14.5 million for the first six months of 2006
      compared to the first six months of 2005 due primarily to a $12.6 million
      increase in transmission expense related to the increase in purchased power
      and
      electric wholesale sales. Additionally, energy efficiency program costs
      increased $3.2 million. Changes in energy efficiency program costs are
      substantially matched with changes in related electric and gas
      revenues.





Maintenance
      expenses for the first six months of 2006 decreased $1.1 million compared
      to the first six months of 2005. Steam generating plant maintenance decreased
      $5.2 million as a result of planned outages in 2005 but was mostly offset
      by increases in maintenance costs related to wind power facilities and the
      electric and gas distribution systems.





Depreciation
      and amortization expense for the first six months of 2006 increased
      $24.4 million compared to the first six months of 2005 due to a
      $21.0 million increase in regulatory expense related to a revenue sharing
      arrangement in Iowa as a result of higher Iowa electric returns on equity
      primarily from improved electric margins. Additionally, utility plant
      depreciation increased due primarily to wind power facilities placed in service
      in the third quarter of 2005. Refer to the “Utility Regulatory Matters” section
      for an explanation of the revenue sharing arrangement.

Nonregulated
      revenues and cost of sales for the first six months of 2006 increased due
      primarily to a change in the management strategy related to certain end-use
      gas
      contracts that resulted in recording prospectively the related revenues and
      cost
      of sales on a gross, rather than net, basis in accordance with Emerging Issues
      Task Force Issue No. 02-3, “Recognition and Reporting of Gains and Losses on
      Energy Trading Contracts Under Issues No. 98-10 and 00-17.” The decrease in
      nonregulated gross margin compared to the first six months of 2005 was
      principally due to a decrease in nonregulated electric margins compared to
      the
      first six months of 2005.

Allowance
      for Equity Funds





As
      a
      regulated public utility, MidAmerican Energy is allowed to capitalize, and
      record as income, a cost of construction for equity funds used, based on
      guidelines set forth by the Federal Energy Regulatory Commission (“FERC”). The
      $5.4 million increase in income for the capitalized allowance on equity
      funds used during construction in the first six months of 2006 was due to the
      increase in construction work in progress compared to the first six months
      of
      2005. MidAmerican Energy expects to continue to record higher-than-normal income
      for the allowance on equity funds used during construction through 2007 while
      the announced generating facilities are constructed.





Other
      Income and Expense





MidAmerican
      Energy -





Interest
      and dividend income increased $2.6 million compared to the first six months
      of 2005 due to a more favorable cash position and higher interest
      rates.





MidAmerican
      Funding -





Other
      income for the first six months of 2006 includes $27.6 million of pre-tax
      gains from the sales of MidAmerican Funding’s shares of common stock of an
      electronic energy and metals trading exchange. Additionally, $4.5 million
      of gain was recognized on shares of that common stock, which MidAmerican Funding
      donated to a charitable foundation. Other expense for the first six months
      of
      2006 reflects $4.5 million of expense for the donation of the shares. Refer
      to Note (9) of MidAmerican Funding’s Notes to Consolidated Financial Statements
      for further discussion of these transactions.





Other
      income for the first six months of 2006 also includes $7.3 million for a
      gain on the sale of MidAmerican Funding’s non-controlling interest in a
      non-utility gas-fired cogeneration facility. Additionally, other income reflects
      $5.2 million of income resulting from changes in a financing arrangement
      related to a non-strategic investment in a hydroelectric generating facility.
      Other income for the first six months of 2005 includes $9.9 million of
      gains from the sale of two non-strategic, passive investments.





Other
      expense for the first six months of 2005 includes the write-downs of some of
      MidAmerican Funding’s investments in commercial passenger aircraft, which it
      accounts for as leveraged leases. The write-downs were the result of actions
      related to a bankruptcy filing by the airline carrier.





Fixed
      Charges





The
      $7.0 million increase in interest on long-term debt was due to the effect
      of $300.0 million of MidAmerican Energy long-term debt issued on
      November 1, 2005, offset partially by maturities of higher rate debt
      in 2005. Other interest expense increased due to a higher balance of the Iowa
      revenue sharing liability. MidAmerican Energy is allowed to capitalize, and
      record as a reduction to fixed charges, a cost of construction for debt funds
      used, based on guidelines set forth by the FERC. The $2.7 million increase
      in allowance for borrowed funds for the first six months of 2006 was due to
      the
      increase in construction work in progress compared to the first six months
      of
      2005. MidAmerican Energy expects to continue to record higher-than-normal
      allowance for borrowed funds used during construction through 2007 while the
      announced generating facilities are constructed.





Income
      Taxes





MidAmerican
      Energy -





Federal
      law currently provides for federal production tax credits for energy produced
      by
      renewable electricity generation projects, including wind power facilities.
      MidAmerican Energy’s income taxes for the first six months of 2006 were reduced
      $7.6 million more by the production tax credits compared to the first six
      months of 2005 due to wind power facilities placed in service in the third
      quarter of 2005.





33




State
      utility rate regulation in Iowa requires that the tax effect of certain timing
      differences be flowed through immediately to customers. Therefore, amounts
      that
      would otherwise have been recognized in income tax expense have been included
      as
      changes in regulatory assets. This flow-through treatment of such timing
      differences impacts the effective tax rates from year to year.





**Liquidity
      and Capital Resources**





MidAmerican
      Energy and MidAmerican Funding have available a variety of sources of liquidity
      and capital resources, both internal and external. These resources provide
      funds
      required for current operations, construction expenditures, dividends, debt
      retirement and other capital requirements.





As
      reflected on the Consolidated Statements of Cash Flows, MidAmerican Energy’s net
      cash provided by operating activities was $388.3 million and
      $305.5 million for the first six months of 2006 and 2005, respectively.
      MidAmerican Funding’s net cash provided by operating activities was
      $366.8 million and $285.1 million for the first six months of 2006 and
      2005, respectively.





Utility
      Construction Expenditures





MidAmerican
      Energy’s primary need for capital is utility construction expenditures. For the
      first six months of 2006, utility construction expenditures incurred totaled
      $319.2 million, including allowance for funds used during construction and
      Quad Cities Station nuclear fuel purchases. Utility construction expenditures
      include accrued amounts and a non-cash computed cost of equity funds. As a
      regulated public utility, MidAmerican Energy is allowed to capitalize, and
      record as income, a cost of equity funds used for construction, based on
      guidelines set forth by the FERC.





Forecasted
      utility construction expenditures, including allowance for funds used during
      construction, total $799 million for 2006. Of that amount,
      $422 million is for the coal-fired and wind-powered generation projects
      discussed below, $61 million is for environmental capital expenditures to
      comply with current and anticipated air quality requirements, and the remaining
      $316 million is for ongoing operational projects including connections for
      new customers, facilities to accommodate load growth and infrastructure
      replacement. Capital expenditure needs are reviewed regularly by management
      and
      may change significantly as a result of such reviews. MidAmerican Energy expects
      to meet these capital expenditures with cash flows from operations and the
      issuance of long-term debt.





MidAmerican
      Energy anticipates a continuing increase in demand for electricity from its
      regulated customers. To meet anticipated demand and ensure adequate electric
      generation in its service territory, MidAmerican Energy is currently
      constructing Council Bluffs Energy Center Unit No. 4 (“CBEC Unit 4”), a 790-MW
      (expected accreditation) super-critical-temperature, coal-fired generating
      plant. MidAmerican Energy will operate the plant and hold an undivided ownership
      interest as a tenant in common with the other owners of the plant. MidAmerican
      Energy's current ownership interest is 60.67%, equating to 479 MW of output.
      Municipal, cooperative and public power utilities will own the remainder, which
      is a typical ownership arrangement for large base-load plants in Iowa. The
      facility will provide service to regulated retail electricity customers.
      Wholesale sales may also be made from the facility to the extent the power
      is
      not immediately needed for regulated retail service. MidAmerican Energy has
      obtained regulatory approval to include the Iowa portion of the actual cost
      of
      the generation project in its Iowa rate base as long as the actual cost does
      not
      exceed the agreed cap that MidAmerican Energy has deemed to be reasonable.
      If
      the cap is exceeded, MidAmerican Energy has the right to demonstrate the
      prudence of the expenditures above the cap, subject to regulatory review.
      MidAmerican Energy expects to invest approximately $737 million in CBEC
      Unit 4, including transmission facilities and excluding allowance for funds
      used
      during construction. Through June 30, 2006, MidAmerican Energy has invested
      $594.0 million in the project, including $121.3 million for
      MidAmerican Energy’s share of deferred payments allowed by the construction
      contract.

On
      December 16, 2005, MidAmerican Energy filed with the IUB a settlement
      agreement between MidAmerican Energy and the Iowa Office of Consumer Advocate
      (“OCA”) regarding ratemaking principles for up to 545 MW (nameplate ratings) of
      wind-powered generation capacity in Iowa to be installed in 2006 and 2007.
      Generally speaking, accredited capacity ratings for wind power facilities are
      considerably less than the nameplate ratings due to the varying nature of wind.
      The settlement agreement was approved by the IUB on April 18, 2006. Refer
      to “Utility Regulatory Matters” below for more information regarding the rate
      aspects of the settlement agreement.





MidAmerican
      Energy has been working with wind project developers and contractors to add
      new
      MidAmerican Energy-owned generation assets. In February 2006, MidAmerican Energy
      entered into agreements to add 99 MW (nameplate ratings) of wind generation
      by
      the end of 2006. In June 2006, MidAmerican Energy entered into an additional
      agreement to add 123 MW (nameplate ratings) of wind generation by the end of
      2007. That same agreement also provides for the sale of development rights
      to an
      adjacent project whose size could be up to 77 MW (nameplate
      ratings).





Nuclear
      Decommissioning





Each
      licensee of a nuclear facility is required to provide financial assurance for
      the cost of decommissioning its licensed nuclear facility. In general,
      decommissioning of a nuclear facility means to safely remove the facility from
      service and restore the property to a condition allowing unrestricted use by
      the
      operator.





MidAmerican
      Energy currently contributes $8.3 million annually to trusts established
      for the investment of funds for decommissioning Quad Cities Station. As of
      June 30, 2006, approximately 55.1% of the fair value of the trusts’ funds
      was invested in domestic common equity securities, 10.9% in domestic corporate
      debt and the remainder in investment grade municipal and U.S. Treasury bonds.
      Funding for Quad Cities Station nuclear decommissioning is reflected as
      depreciation expense in the Consolidated Statements of Operations. Quad Cities
      Station decommissioning costs charged to Iowa customers are included in base
      rates, and recovery of increases in those amounts must be sought through the
      normal ratemaking process.





Contractual
      Obligations and Commercial Commitments





MidAmerican
      Energy and MidAmerican Funding have various contractual obligations and
      commercial commitments. There have been no material changes in the amount of
      such obligations and commitments from what was disclosed in the “Liquidity and
      Capital Resources” section of MD&A in MidAmerican Energy’s and MidAmerican
      Funding’s most recently filed Form 10-K. Refer to Note (3)(c) of Notes to
      Consolidated Financial Statements in this Form 10-Q for discussion regarding
      deferred construction payments and their balance sheet
      classification.





Debt
      Redemption and Issuance





MidAmerican
      Energy’s 6.375% series of medium-term notes, totaling $160.0 million,
      matured on June 15, 2006.





Debt
      Authorizations and Credit Facilities





MidAmerican
      Energy has authority from the FERC to issue through April 14, 2007,
      short-term debt in the form of commercial paper and bank notes aggregating
      $500.0 million. MidAmerican Energy currently has in place a
      $500.0 million revolving credit facility that supports its
      $379.6 million commercial paper program and its variable rate pollution
      control revenue obligations. The facility expires July 6, 2011.





MidAmerican
      Energy currently has the necessary authorizations from the Securities and
      Exchange Commission to issue up to $830.0 million of additional long-term
      securities, from the FERC to issue up to $425.0 million of additional
      long-term securities through November 30, 2006, and from the Illinois
      Commerce Commission (“ICC”) to issue up to $830.0 million of additional
      long-term debt securities through October 22, 2008, and up to
      $600.0 million through July 12, 2011.





35




In
      conjunction with the March 1999 merger, MidAmerican Energy committed to the
      IUB
      to use commercially reasonable efforts to maintain an investment grade rating
      on
      its long-term debt and to maintain its common equity level above 42% of total
      capitalization unless circumstances beyond its control result in the common
      equity level decreasing to below 39% of total capitalization. MidAmerican Energy
      must seek the approval of the IUB of a reasonable utility capital structure
      if
      MidAmerican Energy’s common equity level decreases below 42% of total
      capitalization, unless the decrease is beyond the control of MidAmerican Energy.
      MidAmerican Energy is also required to seek the approval of the IUB if
      MidAmerican Energy’s equity level decreases to below 39%, even if the decrease
      is due to circumstances beyond the control of MidAmerican Energy. If MidAmerican
      Energy’s common equity level were to drop below the required thresholds,
      MidAmerican Energy’s ability to issue debt could be restricted.





Other
      Financing Information





MidAmerican
      Funding or one of its subsidiaries, including MidAmerican Energy, may from
      time
      to time seek to retire its outstanding debt through cash purchases and/or
      exchanges for other securities, in open market purchases, privately negotiated
      transactions or otherwise. The repurchases or exchanges, if any, will depend
      on
      prevailing market conditions, the issuing company’s liquidity requirements,
      contractual restrictions and other factors. The amounts involved may be
      material.





**Credit
      Ratings Risks**





Debt
      and
      preferred securities of MidAmerican Funding and MidAmerican Energy are rated
      by
      nationally recognized credit rating agencies. Assigned credit ratings are based
      on each rating agency’s assessment of MidAmerican Funding’s or MidAmerican
      Energy’s ability to, in general, meet the obligations of the debt or preferred
      securities issued by the rated company. The credit ratings are not a
      recommendation to buy, sell or hold securities, and there is no assurance that
      a
      particular credit rating will continue for any given period of time. As of
      July 28, 2006, MidAmerican Energy’s senior unsecured debt credit ratings
      were as follows: Fitch Ratings, “A/stable;” Moody’s Investor Service,
“A2/stable;” and Standard and Poor’s, “A-/stable.” Other than the energy supply
      and marketing agreements discussed below, neither MidAmerican Funding nor
      MidAmerican Energy has any credit agreements that require termination or a
      material change in collateral requirements or payment schedule in the event
      of a
      downgrade in the credit ratings of the respective company’s
      securities.





In
      conjunction with its risk management activities, MidAmerican Energy must meet
      credit quality standards as required by counterparties. In accordance with
      industry practice, master agreements that govern MidAmerican Energy’s energy
      supply and marketing activities either specifically require it to maintain
      investment grade credit ratings or provide the right for counterparties to
      demand “adequate assurances” in the event of a material adverse change in
      MidAmerican Energy’s creditworthiness. If one or more of MidAmerican Energy’s
      credit ratings decline below investment grade, MidAmerican Energy may be
      required to post cash collateral, letters of credit or other similar credit
      support to facilitate ongoing wholesale energy supply and marketing activities.
      As of June 30, 2006, MidAmerican Energy’s estimated potential collateral
      requirements totaled approximately $144 million. MidAmerican Energy’s
      potential collateral requirements could fluctuate considerably due to
      seasonality, market price volatility, and a loss of key MidAmerican Energy
      generating facilities or other related factors.





**Utility
      Regulatory Matters**





Rate
      Matters





Under
      a
      series of settlement agreements between MidAmerican Energy, the Iowa Office
      of
      Consumer Advocate (“OCA”) and other intervenors approved by the IUB, MidAmerican
      Energy has agreed not to seek a general increase in electric base rates to
      become effective prior to January 1, 2013, unless its Iowa jurisdictional
      electric return on equity for any year falls below 10%. As a party to the
      settlement agreements, the OCA has agreed not to seek any decrease in
      MidAmerican Energy’s Iowa electric base rates prior to
      January 1, 2013. Illinois bundled electric rates are frozen until
      2007, subject to certain exceptions allowing for increases, at which time
      bundled rates may be increased or decreased by the ICC. Refer to Note (4) of
      MidAmerican Energy’s Notes to Consolidated Financial Statements for further
      discussion of these rate matters.





36




In
      an
      order issued September 27, 2004, the IUB required MidAmerican Energy to
      file various plans to fully equalize and consolidate its class zonal electric
      rates by the end of each of the years 2007 through 2010. On
      October 18, 2004, MidAmerican Energy filed a motion for
      reconsideration opposing full rate equalization and proposing a series of rate
      reductions. On March 21, 2005, the IUB required MidAmerican Energy to file
      additional information about potential rate changes concerning phased
      equalization or consolidation of existing zonal rate differences that could
      have
      the effect of bringing rates together on a basis designed to have no impact
      on
      the overall revenues MidAmerican Energy receives from its Iowa electric
      customers. MidAmerican Energy filed the requested information on April 11,
      2005. In the same proceeding, MidAmerican Energy has a pending plan to reduce
      rates for some residential customers by approximately $4.0 million in 2008
      and $3.0 million in 2009 for a total annualized reduction of
      $7.0 million in addition to the reductions to be offset by cost decreases
      related to existing contracts. The $7.0 million reduction in revenues may
      begin to be offset by a rate increase for other residential customers starting
      in 2011. On June 19, 2006, without ruling on revenue requirement issues, the
      IUB
      issued an order requiring MidAmerican Energy to hold informal workshops in
      2007
      and file a comprehensive class cost-of-service study and a revenue neutral
      rate
      equalization/rate consolidation plan by mid-2009.





In
      2004,
      the ICC issued a declaratory ruling finding that MidAmerican Energy’s
      competitive sales of gas to retail customers within the state of Illinois were
      not authorized under the Illinois Public Utilities Act. In its ruling, the
      ICC
      left for subsequent proceedings issues related to the financial implications
      of
      these sales. To date, these issues have been addressed by ICC staff in its
      testimony in the purchased gas adjustment reconciliation proceedings covering
      2001 and 2002. In that testimony, the ICC staff expressed its position that
      MidAmerican Energy must reduce gas costs recovered from Illinois regulated
      gas
      customers through the purchased gas adjustment by the gross margins earned
      from
      MidAmerican Energy’s Illinois nonregulated retail customers since 1996. Gross
      margin is the difference between the revenue and the related cost of gas for
      MidAmerican Energy’s nonregulated sales of gas to retail customers in the entire
      state of Illinois. The ICC has not yet ruled in either case. There can be no
      assurance that the gross margins earned in earlier periods in final purchased
      gas adjustment reconciliation proceedings back to 1996 will not be subject
      to
      challenge. If the ICC accepts the adjustments proposed by its staff and makes
      the same adjustment for the years 2003 - 2004, the total cumulative adjustment
      through November 30, 2004, including the adjustments since 1996, would be
      $7.8 million. In its declaratory ruling, the ICC decided to open a separate
      proceeding, in addition to the purchased gas adjustment reconciliation
      proceedings, to determine an appropriate remedy to impose upon MidAmerican
      Energy for making competitive sales throughout the state of Illinois without
      statutory or regulatory authorization. In its order initiating this separate
      proceeding, the ICC stated there would not be any further litigation of the
      ICC
      conclusions arrived at in the declaratory ruling proceeding, despite the lack
      of
      an evidentiary hearing in that proceeding. An appeal of the order from the
      ICC
      in the declaratory ruling proceeding was filed with the Illinois Appellate
      Court. On May 26, 2006, the court issued an Order dismissing MidAmerican’
Energy’s appeal of the ICC’s action. The court subsequently reaffirmed its
      decision in a July 19, 2006, order in response to MidAmerican Energy’s petition
      for rehearing.





Effective
      January 1, 2005, SB 2525 became law in Illinois. That law allows MidAmerican
      Energy to continue its competitive gas sales in Illinois subject to ICC
      regulation. The ICC still must resolve the historical issues in the on-going
      purchase gas adjustment and related proceedings noted above.





On
      April 18, 2006, MidAmerican Energy filed with the ICC an offer to eliminate
      its monthly adjustment clause for recovery of fuel for electric generation
      and
      purchased power costs in Illinois beginning January 1, 2007, pending
      satisfactory resolution of fuel adjustment clause reconciliation issues. Under
      this proposal, which will not be formally filed until the conclusion of the
      current 2005 fuel adjustment clause reconciliation proceeding, base rates would
      be adjusted to include recoveries at average 2004/2005 cost levels. If approved
      by the ICC, the proposal would expose MidAmerican Energy to monthly market
      price
      changes for fuel and purchased power costs in Illinois, with rate case approval
      required for any base rate changes. Once the fuel adjustment clause is
      eliminated, MidAmerican Energy may not petition for its reinstatement for
      five years.

Transmission
      Developments





On
      July 22, 2005, MidAmerican Energy made a filing with the FERC requesting
      its approval to establish a transmission service coordinator (“TSC”). The TSC
      would be a third party administrator of various MidAmerican Energy Open Access
      Transmission Tariff (“OATT”) functions for transmission service. On
      December 16, 2005, the FERC issued an order conditionally accepting
      MidAmerican Energy’s request to establish a TSC. The order requires MidAmerican
      Energy to make modifications to the draft TSC agreement filed with the FERC
      as
      part of the request and to file a final executed TSC agreement with the FERC
      for
      its review prior to the agreement becoming effective. MidAmerican Energy has
      entered into a contract with a third party vendor to administer MidAmerican
      Energy’s OATT. MidAmerican Energy does not believe that the incremental costs
      will have a material impact on its results of operations, financial position
      or
      cash flows. On June 15, 2006, the FERC issued an order conditionally
      approving MidAmerican Energy’s selection of a third party vendor. MidAmerican
      Energy anticipates the TSC commencing operations on August 30, 2006. Under
      the contract, the vendor would provide its tariff administration and planning
      services for a three-year term.





Electric
      Market Developments





On
      July 13, 2004, the FERC issued an order requiring MidAmerican Energy to
      conduct a study to determine whether MidAmerican Energy or its affiliates
      possess generation market power. MidAmerican Energy is being required to show
      the absence of generation market power in order to be allowed to continue to
      sell wholesale electric power at market-based rates. The FERC order is intended
      to have MidAmerican Energy conform to what has become the FERC’s general
      practice for utilities given authorization to make wholesale market-based sales.
      Under this general practice, utilities authorized to make market-based electric
      sales must submit a new market power study to the FERC every three years.
      MidAmerican Energy filed the required study on October 29, 2004. On
      June 1, 2005, the FERC issued an order setting for investigation the
      reasonableness of MidAmerican Energy’s market-based rates within its control
      area. The order also terminated the previously established November 1,
      2004, refund date and instead required that market-based sales made by
      MidAmerican Energy within its control area beginning August 7, 2005, be
      subject to refund until the matter is resolved. The FERC also required
      MidAmerican Energy to file additional information by July 1, 2005, and
      August 1, 2005. In its August 1, 2005 filing, MidAmerican Energy filed
      a proposed cost-based sales tariff (“CBST”) applicable to sales made within its
      control area to replace its market-based sales tariff. On March 17, 2006,
      the FERC issued an order (“March 17 Order”) accepting MidAmerican Energy’s
      commitment not to make sales using market-based rates in its control area but
      rejected the proposed applicable tariff language. The FERC directed MidAmerican
      Energy to file revised tariff language by April 17, 2006. MidAmerican
      Energy made such filing together with a request for clarification, or in the
      alternative, rehearing (“Request for Clarification”) of the March 17 Order.
      MidAmerican Energy estimates that its maximum potential refund obligation is
      $17 million and its minimum potential refund obligation is $50,000 for the
      period August 7, 2005 through June 30, 2006. The actual refund will depend
      upon the FERC’s ruling on the Request for Clarification and the applicability of
      the CBST to certain sales made within the control area for delivery outside
      the
      control area. MidAmerican Energy does not believe at this time that the ultimate
      outcome of this issue will have a material impact on its results of operations,
      financial position or cash flows.





The
      Energy Policy Act of 2005





On
      August 8, 2005, the Energy Policy Act of 2005 (“Energy Policy Act”) was
      signed into law. That law potentially impacts many segments of the energy
      industry. A tax provision extended the federal production tax credit for new
      renewable electricity generation projects through December 31, 2007. In
      part as a result of that portion of the law, MidAmerican Energy began
      development efforts to add additional wind generation, as previously discussed
      under “Utility Construction Expenditures” above. The law also results in
      expanding FERC regulatory authority in areas such as electric system
      reliability, electric transmission expansion and pricing, regulation of utility
      holding companies, and enforcement authority to issue substantial civil
      penalties. The Energy Policy Act also repealed the Public Utility Holding
      Company Act of 1935 effective February 8, 2006. As a result of the repeal
      and a stock conversion, effective February 9, 2006, Berkshire Hathaway Inc.
      became the majority owner of voting securities of MidAmerican Energy Holdings.

**Environmental
      Matters**





MidAmerican
      Energy’s generating facilities are subject to applicable provisions of the Clean
      Air Act and related air quality standards promulgated by the United States
      Environmental Protection Agency (“EPA”). The Clean Air Act provides the
      framework for regulation of certain air emissions and permitting and monitoring
      associated with those emissions. MidAmerican Energy believes it is in material
      compliance with current air quality requirements.





The
      EPA
      has in recent years implemented and proposed more stringent national ambient
      air
      quality standards. Additionally, legislation is pending, and could be proposed
      in the future, that may impact MidAmerican Energy if enacted. MidAmerican Energy
      has implemented a planning process that forecasts the site-specific controls
      and
      actions that may be required to meet emissions reductions as promulgated by
      the
      EPA. The plan allows MidAmerican Energy to more effectively manage its
      expenditures required to comply with emissions standards. On April 1, 2006,
      MidAmerican Energy submitted to the IUB an updated plan, as required every
      two
      years by Iowa law, which increased its estimate of required expenditures.
      MidAmerican Energy currently estimates that the incremental capital expenditures
      for emission control equipment to comply with air quality requirements will
      total approximately $540 million for January 1, 2006, through
      December 31, 2015. Additionally, MidAmerican Energy expects to incur
      significant incremental operating costs in conjunction with the utilization
      of
      the emissions control equipment. Estimates of the environmental capital and
      operating requirements may change significantly at any time as a result of,
      among other factors, changes in related regulations, prices of products used
      to
      meet the requirements and management’s strategies for achieving compliance with
      the regulations.





Refer
      to
      Note (3)(a) of Notes to Consolidated Financial Statements for further discussion
      of air quality standards affecting MidAmerican Energy.





**Generating
      Capability**





On
      July 20, 2005, retail customer usage of electricity caused a new record
      hourly peak demand of 4,040 MW on MidAmerican Energy’s electric system, 105 MW
      greater than the previous record set in August 2003. MidAmerican Energy is
      interconnected with Iowa utilities and utilities in neighboring states.
      MidAmerican Energy is also a party to an electric generation reserve sharing
      pool and regional transmission group administered by the Mid-Continent Area
      Power Pool (“MAPP”). Each MAPP generation reserve participant is required to
      maintain for emergency purposes a net generating capability reserve of at least
      15% above its system peak demand on a 12-month rolling basis. MidAmerican
      Energy’s reserve margin at peak demand for 2005 was approximately
      26%.





MidAmerican
      Energy believes it has adequate electric capacity reserve through 2009,
      including capacity provided by the generating projects discussed above. However,
      significantly higher-than-normal temperatures during the cooling season could
      cause MidAmerican Energy’s reserve to fall below the 15% minimum. If MidAmerican
      Energy fails to maintain the required minimum reserve, significant penalties
      could be contractually imposed by the MAPP.





MidAmerican
      Energy is financially exposed to movements in energy prices since it does not
      recover its energy costs through an energy adjustment clause in Iowa. Although
      MidAmerican Energy believes it has sufficient generation under typical operating
      conditions for its retail electric needs, a loss of adequate generation by
      MidAmerican Energy requiring the purchase of replacement power at a time of
      high
      market prices could subject MidAmerican Energy to losses on its energy sales.





The
      transmission developments may also impact MidAmerican Energy’s wholesale
      electric purchases and sales. The FERC has proceedings underway which may
      influence the wholesale electric marketplace. Because of the uncertainties
      as to
      future regulatory policy governing transmission service and pricing, and
      regulation of wholesale electric sales, MidAmerican Energy is uncertain whether
      past wholesale costs and revenues will be representative of future wholesale
      costs and revenues.





All
      of
      the coal-fired generating stations operated by MidAmerican Energy are fueled
      by
      low-sulfur, western coal from the Powder River Basin. MidAmerican Energy’s coal
      supply portfolio includes multiple suppliers and mines under agreements of
      varying terms and quantities. MidAmerican Energy typically has one to two years
      of coal supply under contracts with fixed prices and regularly monitors the
      western coal market, looking for opportunities to enhance its coal supply
      portfolio. Operational delays in rail transportation out of the Powder River
      Basin during 2005 and 2006 have resulted in the reduction of coal inventories
      to
      suboptimum levels. MidAmerican Energy believes the transportation issues are
      temporary and that its coal inventories will be restored to preferred levels
      by
      late-2007. Additional information regarding MidAmerican Energy’s coal supply
      contracts is included in Note (4)(e) of Notes to Consolidated Financial
      Statements in Item 8 of its most recently filed Annual Report on Form
      10-K.

**New
      Accounting Pronouncements**





In
      July
      2006, the Financial Accounting Standards Board (“FASB”) issued FASB
      Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - an
      interpretation of FASB Statement No. 109” ** (“FIN
      48”) *.* FIN 48 clarifies the accounting for uncertainty in income taxes recognized
      in accordance with Statement of Financial Accounting Standards No. 109,
“Accounting for Income Taxes,” and 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 return. Guidance is also
      provided on de-recognition, classification, interest and penalties, accounting
      in interim periods, disclosure and transition. FIN 48 is effective for fiscal
      years beginning after December 15, 2006. MidAmerican Funding and
      MidAmerican Energy are currently evaluating the impact of adopting FIN 48 on
      their respective consolidated financial positions and results of
      operations.





**Other
      Matters**





On
      May 25, 2006, the membership of the International Brotherhood of Electrical
      Workers locals 109 and 499, comprising greater than 90% of MidAmerican Energy’s
      represented workforce, ratified a contract between MidAmerican Energy and the
      locals for a term extending through April 30, 2009.





**Critical
      Accounting Policies and Estimates**





MidAmerican
      Energy’s and MidAmerican Funding’s significant accounting policies are described
      in their respective Note (1) of Notes to Consolidated Financial Statements
      in
      Item 8 of their most recently filed Annual Report on Form 10-K. For a discussion
      of their critical accounting policies and estimates, see “Management’s
      Discussion and Analysis of Financial Condition and Results of Operations” in
      their most recently filed Annual Report on Form 10-K. MidAmerican Energy’s and
      MidAmerican Funding’s critical accounting policies have not changed materially
      since December 31, 2005.





**Item
      3.****Quantitative
      and Qualitative Disclosures About Market Risk.**





MidAmerican
      Energy is exposed to loss of net income, cash flows and asset values due to
      market risk, including: 1) changes in the market price of gas, electricity
      and
      fuel used in its regulated and nonregulated businesses, 2) variations in the
      severity of weather conditions from normal, and 3) changes in interest rates.
      To
      manage these exposures, MidAmerican Energy enters into various financial
      derivative instruments, including futures, swaps, options and forward physical
      contracts. Through the functioning of a risk oversight committee, senior
      management provides the overall direction, structure, conduct and control of
      MidAmerican Energy's risk management activities, including authorization and
      communication of risk management policies and procedures, the use of financial
      derivative instruments, strategic hedging program guidelines, appropriate market
      and credit risk limits, and appropriate systems for recording, monitoring and
      reporting the results of transactional and risk management activities.

**PART
      II - OTHER INFORMATION**





**Item
                1.**
            **Legal
                Proceedings.**





MidAmerican
      Energy was one of dozens of companies named as defendants in a January 20,
      2004 consolidated class action lawsuit filed in the United States District
      Court
      for the Southern District of New York. The suit alleged that the defendants
      have
      engaged in unlawful manipulation of the prices of natural gas futures and
      options contracts traded on the New York Mercantile Exchange during the period
      of January 1, 2000 to December 31, 2002. On September 9, 2005,
      MidAmerican Energy and counsel for the plaintiffs executed a stipulation and
      agreement of settlement, which upon final approval by the court following notice
      to all class members, MidAmerican Energy would be dismissed from the lawsuit.
      The court approved the settlement on a preliminary basis on February 8,
      2006, and signed its final judgment and order of dismissal on May 24, 2006.
      No appeal of the order was filed within the applicable appeal period and,
      accordingly, the matter is concluded. MidAmerican Energy’s obligation to the
      plaintiffs was an immaterial amount.





On
      December 28, 2004, an apparent gas explosion and fire resulted in three
      fatalities, one serious injury and property damage at a commercial building
      in
      Ramsey, Minnesota. According to the Minnesota Office of Pipeline Safety, an
      improper installation of a pipeline connection may have been a cause of the
      explosion and fire. A predecessor company to MidAmerican Energy provided gas
      service in Ramsey, Minnesota, at the time of the original installation in 1980.
      In 1993, a predecessor of CenterPoint Energy, Inc. (“CenterPoint”) acquired all
      of the Minnesota gas properties owned by the MidAmerican Energy predecessor
      company.





A s
      a
      result of the explosion and fire, MidAmerican Energy and CenterPoint have
      received settlement demands which total $15.5 million. MidAmerican Energy’s
      exposure, if any, to these demands are covered under its liability insurance
      coverage to which a $2.0 million retention applies. In addition, counsel
      for CenterPoint stated that a replacement program has been initiated for the
      purpose of locating and replacing all mechanical couplings in the former North
      Central Public Service Company properties located in Minnesota. Counsel for
      CenterPoint has represented that the value of the replacement claim may be
      in
      the range of $35-45 million.





Three
      lawsuits are currently on file related to this incident. On February 8,
      2006, MidAmerican Energy was served with a Third Party Complaint filed in U.S.
      District Court, District of Minnesota by CenterPoint Resources Corp. d/b/a
      CenterPoint Energy. The Third Party Complaint seeks contribution and indemnity
      on a wrongful death claim filed by the estate of Lorraine Melton, one of the
      decedents, and all sums associated with CenterPoint’s replacement program.
      CenterPoint Energy Resources Corp. has settled the wrongful death claim with
      the
      trustee for the estate in the Melton case, however, the Third Party action
      by
      CenterPoint Energy Resources Corp. against MidAmerican Energy remains.
      MidAmerican Energy was served with a second Third Party Complaint filed in
      U.S.
      District Court, District of Minnesota by CenterPoint seeking contribution and
      indemnity on a property damage and business interruption claim filed by Ramsey
      Premier Partners, LLC, and all sums associated with CenterPoint’s replacement
      program. MidAmerican Energy filed a motion for summary judgment in both of
      these
      cases on April 27, 2006. An additional complaint filed in Anoka County
      District Court, State of Minnesota, by the estate of Ann Talle seeking damages
      from MidAmerican Energy Holdings and other defendants, including CenterPoint,
      on
      a wrongful death claim arising from this incident was settled by CenterPoint
      during mediation in March 2006, and the court issued a Confidential Order
      Approving Settlement and Distribution of Proceeds on April 7, 2006.
      MidAmerican Energy intends to vigorously defend its position in these claims
      and
      believes their ultimate outcome will not have a material impact on its results
      of operations, financial position or cash flows.





Other
      than the litigation described above, MidAmerican Funding and its subsidiaries
      currently have no material legal proceedings. Information on MidAmerican
      Energy’s environmental matters is included in the “Environmental Matters”
section of MD&A in Item 2 of this Form 10-Q. Information regarding
      MidAmerican Energy’s regulatory matters is included in the “Utility Regulatory
