•	changes in economic, industry, competition or weather conditions, as well as demographic trends, new technologies and various conservation, energy efficiency and distributed generation measures and programs, that could affect customer growth and usage, electricity and natural gas supply or MidAmerican Energy's ability to obtain long-term contracts with customers and suppliers;


•	a high degree of variance between actual and forecasted load or generation that could impact MidAmerican Energy's hedging strategy;


•	performance and availability of MidAmerican Energy's generating facilities, including the impacts of outages and repairs, transmission constraints, weather, including wind, and operating conditions;


•	changes in prices, availability and demand for wholesale electricity, coal, natural gas, other fuel sources and fuel transportation that could have a significant impact on generating capacity and energy costs;

•	risks relating to nuclear generation;


•	the impact of certain contracts used to mitigate or manage volume, price and interest rate risk, including increased collateral requirements, and changes in commodity prices, interest rates and other conditions that affect the fair value of certain contracts;

•	increases in employee healthcare costs, including the implementation of the Affordable Care Act;


•	the impact of investment performance and changes in interest rates, legislation, healthcare cost trends, mortality and morbidity on pension and other postretirement benefits expense and funding requirements;

•	the impact of new accounting guidance or changes in current accounting estimates and assumptions on MidAmerican Funding's or MidAmerican Energy's consolidated financial results;


•	the effects of catastrophic and other unforeseen events, which may be caused by factors beyond MidAmerican Energy's control or by a breakdown or failure of its operating assets, including storms, floods, fires, explosions, litigation, wars, terrorism and embargoes; and


•	other business or investment considerations that may be disclosed from time to time in MidAmerican Funding's or MidAmerican Energy's filings with the United States Securities and Exchange Commission or in other publicly disseminated written documents.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholder of

MidAmerican Energy Company

Des Moines, Iowa

We have reviewed the accompanying balance sheet of MidAmerican Energy Company (the "Company") as of ~~September~~June 30, ~~2014~~2015, and the related statements of operations and comprehensive income for the three-month and ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, and of changes in equity and cash flows for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014. 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 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 balance sheet and statement of capitalization (not presented herein) of MidAmerican Energy Company as of December 31, ~~2013~~2014, and the related statements of operations, comprehensive income, changes in equity and cash flows for the year then ended (not presented herein); and in our report dated ~~March 3~~February 27, ~~2014~~2015, we expressed an unqualified opinion on those financial statements. In our opinion, the information set forth in the accompanying balance sheet as of December 31, ~~2013~~2014 is fairly stated, in all material respects, in relation to the balance sheet from which it has been derived.

MIDAMERICAN ENERGY COMPANY

NOTES TO FINANCIAL STATEMENTS

(Unaudited)


(1)	General

MidAmerican Energy Company ("MidAmerican Energy") is a public utility with electric and natural gas operations and is the principal subsidiary of MHC Inc. ("MHC"). MHC is a holding company that conducts no business other than the ownership of its subsidiaries and related corporate services. MHC's nonregulated subsidiaries include Midwest Capital Group, Inc. and MEC Construction Services Co. MHC is the direct, wholly owned subsidiary of MidAmerican Funding, LLC ("MidAmerican Funding"), which is an Iowa limited liability company with Berkshire Hathaway Energy Company ("BHE") as its sole member. BHE is a consolidated subsidiary of Berkshire Hathaway Inc. ("Berkshire Hathaway").

The unaudited Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the unaudited Financial Statements as of ~~September~~June 30, ~~2014~~2015, and for the three- and ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014. The results of operations for the three- and ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015, are not necessarily indicative of the results to be expected for the full year.

The preparation of the unaudited Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Financial Statements. Note 2 of Notes to Financial Statements included in MidAmerican Energy's Annual Report on Form 10-K for the year ended December 31, ~~2013~~2014, describes the most significant accounting policies used in the preparation of the unaudited Financial Statements. There have been no significant changes in MidAmerican Energy's assumptions regarding significant accounting estimates and policies during the ~~nine~~six-month period ended ~~September~~June 30, ~~2014~~2015.

Utility Plant Depreciation Rates

Effective January 1, 2014, MidAmerican Energy revised depreciation rates for certain electric generating facilities based on the results of its 2013 Iowa electric retail rate case. The new depreciation rates reflect longer estimated useful lives for certain generating facilities. The effect of this change was to reduce depreciation and amortization expense by $50 million annually, or $13 million and $38 million for the three- and nine-month periods ended September 30, 2014, respectively, based on depreciable plant balances at the time of the change. In August 2013, MidAmerican Energy revised its depreciation rates for certain electric generating facilities based on the results of a new depreciation study. The new rates reflect longer estimated useful lives for wind-powered generating facilities placed in service in 2011 and 2012 and a lower accrual rate for the cost of removal regulatory liability related to coal-fueled generating facilities. The effect of this change was to reduce depreciation and amortization expense by $49 million annually, or $13 million and $37 million for the three- and nine-month periods ended September 30, 2014, respectively, based on depreciable plant balances at the time of the change.

In ~~May~~April ~~2014~~2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. ~~2014~~ 2015-0903, which ~~creates~~amends FASB Accounting Standards Codification ("ASC") ~~Topic~~Subtopic ~~606~~835-30, "~~Revenue~~Interest ~~from~~- ~~Contracts~~Imputation ~~with~~of ~~Customers" and supersedes ASC Topic 605, "Revenue Recognition~~Interest." The ~~guidance~~amendments ~~replaces~~in ~~industry-specific~~this guidance ~~and~~require ~~establishes a single five-step model to identify and recognize revenue. The core principle of the guidance is~~ that andebt ~~entity~~issuance ~~should~~costs ~~recognize~~related ~~revenue upon transfer of control of promised goods or services~~ to ~~customers~~a inrecognized andebt ~~amount~~liability ~~that reflects the consideration to which an entity expects to~~ be ~~entitled~~presented in ~~exchange for those goods or services.

This guidance is effective for interim and annual reporting periods beginning after December 15, ~~2016.~~2015, ~~Early~~with ~~application~~early isadoption ~~not~~ permitted. This guidance ~~may~~must be adopted retrospectively, orwherein ~~under~~the abalance ~~modified~~sheet ~~retrospective~~of ~~method~~each ~~where~~period ~~the~~presented ~~cumulative~~should ~~effect~~be isadjusted ~~recognized~~to atreflect the ~~date~~new ~~of initial application~~guidance. MidAmerican Energy is currently evaluating the impact of adopting this guidance on its Financial Statements and disclosures included within Notes to Financial Statements.

In May 2014, the FASB issued ASU No. 2014-09, which creates FASB ASC Topic 606, "Revenue from Contracts with Customers" and supersedes ASC Topic 605, "Revenue Recognition." The guidance replaces industry-specific guidance and establishes a single five-step model to identify and recognize revenue. The core principle of the guidance is that an entity should recognize revenue upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. Additionally, the guidance requires the entity to disclose further quantitative and qualitative information regarding the nature and amount of revenues arising from contracts with customers, as well as other information about the significant judgments and estimates used in recognizing revenues from contracts with customers. In July 2015, the FASB decided to defer the effective date one year to interim and annual reporting periods beginning after December 15, 2017. This guidance may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. MidAmerican Energy is currently evaluating the impact of adopting this guidance on its Financial Statements and disclosures included within Notes to Financial Statements.

In February 2013, the FASB issued ASU No. 2013-04, which amends FASB ASC Topic 405, "Liabilities." The amendments in this guidance require an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the amount the reporting entity agreed to pay plus any additional amounts the reporting entity expects to pay on behalf of its co-obligor. Additionally, the guidance requires the entity to disclose the nature and amount of the obligation, as well as other information about those obligations. MidAmerican Energy adopted this guidance on January 1, 2014. The adoption of this guidance did not have a material impact on MidAmerican Energy's disclosures included within Notes to Financial Statements.

(4) ~~Recent~~Income ~~Financing Transactions~~Taxes

In April 2014, MidAmerican Energy issued $150 million of its 2.40% First Mortgage Bonds due March 2019, $300 million of its 3.50% First Mortgage Bonds due October 2024 and $400 million of its 4.40% First Mortgage Bonds due October 2044. The net proceeds were used for the optional redemption in May 2014 of $350 million of MidAmerican Energy's 4.65% Senior Notes due October 2014 and for general corporate purposes.

(5) Income Taxes

A reconciliation of the federal statutory income tax rate to MidAmerican Energy's effective income tax rate applicable to income before income tax benefit is as follows:

Other, net	—		(1	)	—		(1	)
Effective income tax rate	(2852	)%	(4239	)%	(2642	)%	(3725	)%

Income tax credits relate primarily to production tax credits ~~earned~~from by MidAmerican Energy's wind-powered generating facilities. Federal renewable electricity production tax credits are earned as energy from qualifying wind-powered generating facilities is produced and sold and are based on a per-kilowatt hour rate pursuant to the applicable federal income tax law. Wind-powered generating facilities are eligible for the credits for 10 years from the date the qualifying generating facilities are placed in service.

Berkshire Hathaway includes BHE and subsidiaries in its United States federal income tax return. Consistent with established regulatory practice, MidAmerican Energy's provision for income taxes has been computed on a stand-alone basis, and substantially all of its currently payable or receivable income taxes are remitted to or received from BHE. MidAmerican Energy received net cash ~~receipts~~payments for income taxes from BHE totaling $~~150~~ 373 million and $17 86 million for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, respectively.

(65) Employee Benefit Plans

MidAmerican Energy sponsors a noncontributory defined benefit pension plan covering a majority of all employees of BHE and its domestic energy subsidiaries other than PacifiCorp and NV Energy, Inc. MidAmerican Energy also sponsors certain postretirement healthcare and life insurance benefits covering substantially all retired employees of BHE and its domestic energy subsidiaries other than PacifiCorp and NV Energy, Inc. ~~Net periodic benefit cost for the plans of MidAmerican Energy and the aforementioned affiliates included the following components (in millions):~~

MidAmerican Energy is principally exposed to electricity, natural gas, coal and fuel oil commodity price risk as it has an obligation to serve retail customer load in its regulated service territory. MidAmerican Energy also provides nonregulated retail electricity and natural gas services in competitive markets. MidAmerican Energy's load and generating facilities represent substantial underlying commodity positions. Exposures to commodity prices consist mainly of variations in the price of fuel required to generate electricity, wholesale electricity that is purchased and sold, and natural gas supply for retail customers. Commodity prices are subject to wide price swings as supply and demand are impacted by, among many other unpredictable items, weather; market liquidity; generating facility availability; customer usage; storage; and transmission and transportation constraints. Interest rate risk exists on variable-rate debt and future debt issuances. MidAmerican Energy does not engage in a material amount of proprietary trading activities.Activities

MidAmerican Energy is exposed to the impact of market fluctuations in commodity prices and interest rates. MidAmerican Energy is principally exposed to electricity, natural gas, coal and fuel oil commodity price risk as it has an obligation to serve retail customer load in its regulated service territory. MidAmerican Energy also provides nonregulated retail electricity and natural gas services in competitive markets, which creates contractual obligations to provide electric and natural gas services. MidAmerican Energy's load and generating facilities represent substantial underlying commodity positions. Exposures to commodity prices consist mainly of variations in the price of fuel required to generate electricity, wholesale electricity that is purchased and sold, and natural gas supply for retail customers. Commodity prices are subject to wide price swings as supply and demand are impacted by, among many other unpredictable items, weather; market liquidity; generating facility availability; customer usage; storage; and transmission and transportation constraints. Interest rate risk exists on variable-rate debt and future debt issuances. MidAmerican Energy does not engage in a material amount of proprietary trading activities.

MidAmerican Energy has established a risk management process that is designed to identify, assess, monitor, report, manage and mitigate each of the various types of risk involved in its business. To mitigate a portion of its commodity price risk, MidAmerican Energy uses commodity derivative contracts, which may include forwards, futures, options, swaps and other agreements, to effectively secure future supply or sell future production generally at fixed prices. MidAmerican Energy manages its interest rate risk by limiting its exposure to variable interest rates primarily through the issuance of fixed-rate long-term debt and by monitoring market changes in interest rates. Additionally, MidAmerican Energy may from time to time enter into interest rate derivative contracts, such as interest rate swaps or locks, to mitigate its exposure to interest rate risk. MidAmerican Energy does not hedge all of its commodity price and interest rate risks, thereby exposing the unhedged portion to changes in market prices.

There have been no significant changes in MidAmerican Energy's accounting policies related to derivatives. Refer to Note 87 for additional information on derivative contracts.

MidAmerican Energy analyzes the financial condition of each significant wholesale counterparty before entering into any transactions, establishes limits on the amount of unsecured credit to be extended to each counterparty and evaluates the appropriateness of unsecured credit limits on an ongoing basis. To mitigate exposure to the financial risks of wholesale counterparties, MidAmerican Energy enters into netting and collateral arrangements that may include margining and cross-product netting agreements and obtains third-party guarantees, letters of credit and cash deposits. Counterparties may be assessed fees for delayed payments. If required, MidAmerican Energy exercises rights under these arrangements, including calling on the counterparty's credit support arrangement.

MidAmerican Energy also has potential indirect credit exposure to other market participants in the regional transmission organization ("RTO") markets where it actively participates, including the Midcontinent Independent System Operator, Inc. and the PJM Interconnection, L.L.C.

Collateral and Contingent Features

In accordance with industry practice, certain wholesale derivative contracts contain credit support provisions that in part base MidAmerican Energy's collateral requirements on its credit ratings for senior unsecured debt as reported by one or more of the three recognized credit rating agencies. These derivative contracts may either specifically provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features") or provide the right for counterparties to demand "adequate assurance," or in some cases terminate the contract, in the event of a material adverse change in MidAmerican Energy's creditworthiness. These rights can vary by contract and by counterparty. As of ~~September~~June 30, ~~2014~~2015, MidAmerican Energy's credit ratings from the three recognized credit rating agencies were investment grade.

The 14aggregate fair value of MidAmerican Energy's derivative contracts in liability positions with specific credit-risk-related contingent features totaled $60 million and $52 million as of June 30, 2015 and December 31, 2014, respectively, for which MidAmerican Energy had posted collateral of $- million at each date. If all credit-risk-related contingent features for derivative contracts in liability positions had been triggered as of June 30, 2015 and December 31, 2014, MidAmerican Energy would have been required to post $52 million and $36 million, respectively, of additional collateral. MidAmerican Energy's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation, or other factors.

~~The~~ aggregate fair value of MidAmerican Energy's derivative contracts in liability positions with specific credit-risk-related contingent features totaled $33 million and $35 million as of September 30, 2014 and December 31, 2013, respectively, for which MidAmerican Energy had posted collateral of $- million. If all credit-risk-related contingent features for derivative contracts in liability positions had been triggered as of September 30, 2014 and December 31, 2013, MidAmerican Energy would have been required to post $15 million and $24 million, respectively, of additional collateral. MidAmerican Energy's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation, or other factors.13

(87) Fair Value Measurements

The carrying value of MidAmerican Energy's cash, certain cash equivalents, receivables, payables, accrued liabilities and short-term borrowings approximates fair value because of the short-term maturity of these instruments. MidAmerican Energy has various financial assets and liabilities that are measured at fair value on the Financial Statements using inputs from the three levels of the fair value hierarchy. A financial asset or liability classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows:


•	Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that MidAmerican Energy has the ability to access at the measurement date.

•

Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).


•	Level 3 — Unobservable inputs reflect MidAmerican Energy's judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. MidAmerican Energy develops these inputs based on the best information available, including its own data.

1615

Derivative contracts are recorded on the Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchases or normal sales and qualify for the exception afforded by GAAP. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which MidAmerican Energy transacts. When quoted prices for identical contracts are not available, MidAmerican Energy uses forward price curves. Forward price curves represent MidAmerican Energy's estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates. MidAmerican Energy bases its forward price curves upon market price quotations, when available, or internally developed and commercial models, with internal and external fundamental data inputs. Market price quotations are obtained from independent energy brokers, exchanges, direct communication with market participants and actual transactions executed by MidAmerican Energy. Market price quotations are generally readily obtainable for the applicable term of MidAmerican Energy's outstanding derivative contracts; therefore, MidAmerican Energy's forward price curves reflect observable market quotes. Market price quotations for certain electricity and natural gas trading hubs are not as readily obtainable due to the length of the contract. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, MidAmerican Energy uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of underlying forward commodity prices, interest rates, related volatility, counterparty creditworthiness and duration of contracts. Refer to Note 76 for further discussion regarding MidAmerican Energy's risk management and hedging activities.

MidAmerican Energy's investments in money market mutual funds and debt and equity securities are stated at fair value and are primarily accounted for as available-for-sale securities ~~and are stated at fair value~~. When available, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. In the absence of a quoted market price or net asset value of an identical security, the fair value is determined using pricing models or net asset values based on observable market inputs and quoted market prices of securities with similar characteristics. The fair value of MidAmerican Energy's investments in auction rate securities, where there is no current liquid market, is determined using pricing models based on available observable market data and MidAmerican Energy's judgment about the assumptions, including liquidity and nonperformance risks, which market participants would use when pricing the asset.

MidAmerican Energy's long-term debt is carried at cost on the Financial Statements. The fair value of MidAmerican Energy's long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying value of MidAmerican Energy's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates. The following table presents the carrying value and estimated fair value of MidAmerican Energy's long-term debt (in millions):

(109) Segment Information

MidAmerican Energy has identified three reportable segments: regulated electric, regulated gas and nonregulated energy. 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. 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 revenue by transporting gas owned by others through its distribution system. Pricing for regulated electric and regulated 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. The nonregulated energy segment derives most of its revenue from nonregulated retail electric and gas activities. Common operating costs, interest income, interest expense and income tax expense are allocated to each segment based on certain factors, which primarily relate to the nature of the cost.

(10) 19Transfer of Nonregulated Energy Operations

In the second quarter of 2015, MidAmerican Energy filed with the Iowa Utilities Board and Illinois Commerce Commission for approval to transfer the operations, assets and liabilities of its unregulated retail services business to a subsidiary of BHE. The transfer, which would include substantially all of the net assets of MidAmerican Energy's nonregulated energy reportable segment, would be made at MidAmerican Energy’s carrying value of the assets and liabilities, resulting in no gain or loss. The transaction would be accounted for as a dividend and is expected to occur in the first quarter of 2016.

The unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Consolidated Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the unaudited Consolidated Financial Statements as of ~~September~~June 30, ~~2014~~2015, and for the three- and ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014.

The preparation of the unaudited Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Consolidated Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Consolidated Financial Statements. Note 2 of Notes to Consolidated Financial Statements included in MidAmerican Funding's Annual Report on Form 10-K for the year ended December 31, ~~2013~~2014, describes the most significant accounting policies used in the preparation of the unaudited Consolidated Financial Statements.

(8) Fair Value Measurements

Refer to Note 8 of MidAmerican Energy's Notes to Financial Statements.

MidAmerican Funding's long-term debt is carried at cost on the Consolidated Financial Statements. The fair value of MidAmerican Funding's long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying value of MidAmerican Funding's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates. The following table presents the carrying value and estimated fair value of MidAmerican Funding's long-term debt (in millions):

(98) Commitments and Contingencies

MidAmerican Funding is party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. MidAmerican Funding does not believe that such normal and routine litigation will have a material impact on its consolidated financial results.

Refer to Note 98 of MidAmerican Energy's Notes to Financial Statements.

(109) Segment Information

MidAmerican Funding has identified three reportable segments: regulated electric, regulated gas and nonregulated energy. 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. 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 revenue by transporting gas owned by others through its distribution system. Pricing for regulated electric and regulated 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. The nonregulated energy segment derives most of its revenue from nonregulated retail electric and gas activities. Common operating costs, interest income, interest expense and income tax expense are allocated to each segment based on certain factors, which primarily relate to the nature of the cost. "Other" in the tables below consists of the nonregulated subsidiaries of MidAmerican Funding not engaged in the energy business and parent company interest expense.

The following tables provide information on a reportable segment basis (in millions):

Regulated gas revenue includes 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 directly affect gross margin or net income because regulated gas revenue reflects comparable fluctuations through the purchased gas adjustment clauses.

Effective January 1, 2014, MidAmerican Energy revised depreciation rates for certain electric generating facilities based on the results of its 2013 Iowa electric retail rate case. The new depreciation rates reflect longer estimated useful lives for certain generating facilities. The effect of this change was to reduce depreciation and amortization expense by $50 million annually based on depreciable plant balances at the time of the change. In August 2013, MidAmerican Energy revised its depreciation rates for certain electric generating facilities based on the results of a new depreciation study. The new rates reflect longer estimated useful lives for wind-powered generating facilities placed in service in 2011 and 2012 and a lower accrual rate for the cost of removal regulatory liability related to coal-fueled generating facilities. The effect of this change was to reduce depreciation and amortization expense by $49 million annually based on depreciable plant balances at the time of the change.

~~For~~ the third quarter of 2014 compared to 2013, nonregulated operating revenue and cost of sales increased due to higher prices and per-unit costs, respectively, for electric and gas sales and higher nonregulated electric sales volumes, partially offset by a decrease in nonregulated gas sales volumes. Nonregulated gross margin decreased due to a lower average margin per unit sold on nonregulated electric sales.32

For the ~~first~~second ~~nine~~quarter ~~months~~ of ~~2014~~2015 compared to ~~2013~~2014, nonregulated operating revenue and cost of sales increased ~~primarily~~ due to higher nonregulated electric volumes, prices and per-unit costs, ~~respectively,~~partially ~~for~~offset ~~gas~~by ~~and~~lower ~~electric~~prices, ~~sales.~~per-unit ~~The~~costs ~~impact~~and ofvolumes afor ~~decrease in~~ nonregulated gas ~~sales volumes was largely offset by an increase in nonregulated electric sales volumes~~activities.

~~MidAmerican~~For ~~Funding~~the first six months of 2015 compared to 2014, nonregulated operating revenue and cost of sales decreased due to lower prices and per-unit costs on lower gas volumes, partially offset by an increase in nonregulated electric volumes, prices and per-unit costs. Nonregulated gross margin decreased due to lower average margins per unit sold on nonregulated gas sales, lower nonregulated gas sales and lower income from the portion of margins on regulated gas wholesale sales that is retained by MidAmerican Energy, partially offset by higher nonregulated electric sales and average margins per unit sold.

MidAmerican Funding's nonregulated gross margin decreased $2 million and increased $13 million for the third quarter and first nine months of 2014 compared to 2013, respectively. In addition to the factors in MidAmerican Energy's discussion above, MidAmerican Funding's nonregulated gross margin for the first nine months of 2014 increased due to two construction projects in 2014 at a nonregulated utility construction subsidiary.

Nonregulated Other Operating Expenses

MidAmerican Funding -

Nonregulated other operating expenses of $33 million for the first nine months of 2014 increased $10 million compared to 2013 primarily due to expenses related to two construction projects in 2014 at a nonregulated utility construction subsidiary.

Non-Operating Income

MidAmerican Energy -

Allowance for equity funds ofdecreased $114 million for the ~~third~~second quarter of ~~2014~~2015 and $308 million for the first ~~nine~~six months of ~~2014~~2015 ~~increased $7 million and $18 million, respectively,~~ compared to ~~2013~~2014 primarily due to ~~higher~~lower construction work-in-progress balances related to the ~~construction~~installation of ~~wind-powered~~emissions control equipment at a number of MidAmerican Energy's jointly owned generating facilities. MidAmerican Energy's other, net decreased $3 million for the second quarter of 2015 and $1 million for the first six months of 2015 compared to 2014 primarily due to fluctuations in returns from corporate-owned life insurance policies.

MidAmerican 34Funding -

In addition to the fluctuations discussed for MidAmerican Energy, MidAmerican Funding's other, net for the first six months of 2015 reflects a $13 million pre-tax gain on the sale of an investment in a generating facility lease in 2015.

Income Tax Benefit

MidAmerican Energy -

MidAmerican Energy's income tax benefit ~~was~~increased $3736 million for the ~~third~~second quarter of ~~2014,~~2015 ~~a decrease of $6 million~~ compared to ~~$43 million for 2013~~2014, ~~with~~and anthe effective tax ~~rate~~rates ofwere (2852)% for ~~2014~~2015 and (4239)% for ~~2013~~2014. The ~~decrease~~increase in income tax benefit for the ~~third~~second quarter of ~~2014~~2015 was due to ~~higher~~an ~~pre-tax income, partially offset by a $2 million~~ increase in recognized production tax credits. ~~MidAmerican Energy's income tax benefit was $75 million for the first nine months of 2014, an increase of $2 million compared to $73 million for 2013, with an effective tax rate of (26)% for 2014~~ and ~~(37)% for 2013. The increase in income tax benefit for~~ the ~~first~~effects ~~nine months~~ of ~~2014 was due to an increase of $26 million in recognized production tax credits~~ratemaking, ~~substantially~~partially offset by ~~higher pre-tax income. The change in~~ the ~~effective~~impact ~~tax rates for the third quarter and first nine months~~ of ~~2014~~a ~~was primarily due to~~ higher pre-tax income~~, partially offset by the increase in recognized production tax credits~~.

Production tax credits are recognized in earnings for interim periods based on the application of an estimated annual effective tax rate to pretax earnings. Federal renewable electricity production tax credits are earned as energy from qualifying wind-powered generating facilities is produced and sold and are based on a per-kilowatt hour rate pursuant to the applicable federal income tax law. Production tax credits recognized in the second quarter of 2015 were $57 million, or $43 million higher than the second quarter of 2014, while production tax credits earned in the second quarter of 2015 were $48 million, or $3 million higher than the second quarter of 2014 primarily due to wind-powered generation placed in service in late 2014. Production tax credits recognized in the first six months of 2015 were $98 million, or $16 million higher than the first six months of 2014, while production tax credits earned in the first six months of 2015 were $107 million, or $7 million higher than the first six months of 2014 primarily due to wind-powered generation placed in service in late 2014. The difference between production tax credits recognized and earned of $9 million as of June 30, 2015 will be recorded in earnings over the remainder of 2015.

MidAmerican Funding -

MidAmerican Funding's income tax benefit ~~was~~increased $3936 million for the ~~third~~second quarter of ~~2014~~2015, ~~a decrease of $6 million compared to $45 million for 2013, with an effective tax rate of (30)% for 2014~~ and ~~(46)% for 2013.

The change in the income tax benefit ~~and effective tax rates~~ was ~~due~~ principally due to the factors discussed for MidAmerican Energy.

MidAmerican 35Funding's income tax benefit increased $24 million for the first six months of 2015, and the effective tax rates were (40)% for 2015 and (28)% for 2014. The change in the income tax benefit was principally due to the factors discussed for MidAmerican Energy, partially offset by income tax expense related to the gain on the sale of an investment in a generating facility lease in 2015.

Liquidity and Capital Resources

As of ~~September~~June 30, ~~2014~~2015, MidAmerican Energy's total net liquidity was $~~806~~712 million consisting of $~~396~~302 million of cash and cash equivalents and $605 million of ~~revolving~~ credit facilities reduced by $195 million of the ~~revolving~~ credit facilities reserved to support MidAmerican Energy's variable-rate tax-exempt bond obligations. As of ~~September~~June 30, ~~2014~~2015, MidAmerican Funding's total net liquidity was $~~811~~717 million, including $1 million of additional cash and cash equivalents and MHC Inc.'s $4 million ~~revolving~~ credit facility.

Operating Activities

MidAmerican Energy's net cash flows from operating activities for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, were $~~683~~753 million and $~~589~~400 million, respectively. MidAmerican Funding's net cash flows from operating activities for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, were $~~679~~746 million and $~~575~~396 million, respectively. The ~~increases~~changes in net cash flows were predominantly due to the timing of MidAmerican Energy's income tax cash flows with BHE, which ~~reflect~~totaled ~~the~~net ~~payment~~cash inreceipts ~~2013~~from BHE of $~~159~~ 373 million ofand ~~income~~$86 ~~tax~~million ~~liability~~for ~~generated~~the infirst ~~2012,~~six ~~and~~months ~~higher~~of ~~gross~~2015 ~~margins for regulated electric~~ and ~~regulated gas businesses~~2014, ~~partially~~respectively. ~~offset~~Income bytax ~~greater~~cash ~~collateral~~flows ~~requirements~~for ~~related~~2015 toreflect ~~derivative~~the ~~positions~~receipt ~~and~~of ~~higher~~$255 million ~~interest paid as a result~~ of ~~the~~income ~~issuance~~tax ofbenefits ~~long-term~~generated ~~debt~~ in ~~September 2013~~2014.

In December 2014, the Tax Increase Prevention Act of 2014 (the "Act") was signed into law, extending the 50% bonus depreciation for qualifying property purchased and placed in-service before January 1, 2015 and before January 1, 2016 for certain longer-lived assets. Production tax credits were extended for wind power and other forms of non-solar renewable energy projects that begin construction before the end of 2014. As a result of the Act, MidAmerican Energy's cash flows from operations have benefited in 2015 due to bonus depreciation on qualifying assets placed in-service and for production tax credits earned on qualifying projects.

Investing Activities

MidAmerican Energy's net cash flows from investing activities for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, were $(~~964~~430) million and $(~~588~~431) million, respectively. MidAmerican Funding's net cash flows from investing activities for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, were $(~~962~~417) million and $(~~588~~429) million, respectively. Net cash flows from investing activities consist almost entirely of utility construction expenditures, which ~~increased~~were ~~for~~relatively ~~2014~~unchanged ~~principally due to expenditures~~ for the ~~construction~~first ofsix ~~wind-powered~~months ~~generating facilities and Multi-Value transmission projects. As~~ of ~~September 30,~~2015 ~~2014,~~compared ~~MidAmerican~~to ~~Energy has placed in service 150 MW (nominal ratings) of additional wind-powered generation in~~ 2014. Purchases and proceeds related to available-for-sale securities primarily consist of activity within the Quad Cities Generating Station nuclear decommissioning trust. MidAmerican Funding received $13 million in 2015 related to the sale of an investment in a generating facility lease.

Financing Activities

MidAmerican Energy's net cash flows from financing activities for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014 were $~~483~~(50) million and $~~787~~484 million, respectively. MidAmerican Funding's net cash flows from financing activities for the ~~nine~~six-month periods ended ~~September~~June 30, ~~2014~~2015 and ~~2013~~2014, were $~~486~~(56) million and $~~801~~486 million, respectively. In 2015, MidAmerican Energy made repayments totaling $50 million through its commercial paper program. In April 2014, MidAmerican Energy issued $150 million of ~~its~~ 2.40% First Mortgage Bonds due March 2019, $300 million of ~~its~~ 3.50% First Mortgage Bonds due October 2024 and $400 million of ~~its~~ 4.40% First Mortgage Bonds due October 2044. The net proceeds were used for the optional redemption in May 2014 of $350 million of MidAmerican Energy's 4.65% Senior Notes due October 2014 and for general corporate purposes. ~~In January 2013,~~ MidAmerican ~~Energy~~Funding paid ~~common dividends of~~ $~~125~~6 million ~~to MHC Inc. and,~~ in ~~April 2013,~~2015 paid $28 million for the redemption of all outstanding shares of its preferred securities. In September 2013, MidAmerican Energy issued $350 million of its 2.40% First Mortgage Bonds due March 2019, $250 million of its 3.70% First Mortgage Bonds due September 2023 and ~~$350 million of its 4.80% First Mortgage Bonds due September 2043. MidAmerican Funding~~ received $32 million in 2014 ~~and paid $111 million in 2013~~ through its note payable with BHE.

Additionally, MidAmerican Energy has a $5 million unsecured credit facility for general corporate purposes.

MidAmerican Energy currently has an effective registration statement with the United States Securities and Exchange Commission to issue up to $800 million of long-term debt securities through November 12, 2016. Additionally, MidAmerican Energy has authorization from the FERC to issue through ~~December~~March 3031, ~~2015~~2017, long-term securities totaling up to $751.70 ~~million~~billion at interest rates not to exceed the applicable United States Treasury rate plus a spread of 175 basis points. MidAmerican Energy has ~~authorization~~authorizations from the Illinois Commerce Commission to issue up to an aggregate of $800 million of additional long-term debt securities, of which $50 million expires December 19, 2015, and $750 million expires December 9, 2016.

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. As of ~~September~~June 30, ~~2014~~2015, MidAmerican Energy's common equity ratio was 5052% computed on a basis consistent with its commitment.

Future Uses of Cash

MidAmerican Energy and MidAmerican Funding have available a variety of sources of liquidity and capital resources, both internal and external, including net cash flows from operating activities, public and private debt offerings, the issuance of commercial paper, the use of unsecured revolving credit facilities, and other sources. These sources are expected to provide funds required for current operations, capital expenditures, debt retirements and other capital requirements. The availability and terms under which MidAmerican Energy and MidAmerican Funding have access to external financing depends on a variety of factors, including their credit ratings, investors' judgment of risk and conditions in the overall capital markets, including the condition of the utility industry.

Utility Construction Expenditures

MidAmerican Energy's primary need for capital is utility construction expenditures. Capital expenditure needs are reviewed regularly by management and may change significantly as a result of these reviews, which may consider, among other factors, changes in environmental and other rules and regulations; impacts to customers' rates; outcomes of regulatory proceedings; changes in income tax laws; general business conditions; load projections; system reliability standards; the cost and efficiency of construction labor, equipment and materials; commodity prices; and the cost and availability of capital. Prudently incurred expenditures for compliance-related items such as pollution-control technologies, replacement generation, nuclear decommissioning and associated operating costs are generally incorporated into MidAmerican Energy's regulated retail rates.

MidAmerican Energy's ~~forecasted~~forecast utility construction expenditures, which exclude amounts for non-cash equity AFUDC and other non-cash items, are approximately $1.65 billion for ~~2014~~2015 and include:

• $~~792~~791 million for the construction of ~~1,006~~657 MW (nominal ratings) of wind-powered generating facilities expected to be placed in service in ~~2014~~2015, ~~and~~including 162 MW (nominal ratings) approved by the IUB in February 2015.

• $~~153~~166 million for ~~Multi-Value~~transmission ~~Projects~~MVP ~~approved~~investments. byMidAmerican Energy has approval from the Midcontinent Independent System Operator, Inc. for the construction of four MVPs located in Iowa and Illinois, which will add approximately 245 miles of 345 kV transmission line ~~located~~to inMidAmerican ~~Iowa~~Energy's ~~and~~transmission ~~Illinois~~system, with remaining expenditures predominantly in ~~2014 to~~ 2016.

• 37Remaining costs primarily relate to routine expenditures for distribution, generation, transmission and other infrastructure needed to serve existing and expected demand.

•In ~~$82~~April ~~million~~2015, MidAmerican Energy filed with the IUB an application for ~~emissions~~ratemaking ~~control~~principles ~~equipment,~~related ~~primarily~~to atthe ~~George~~construction ~~Neal~~of ~~Energy~~up ~~Center~~to ~~Units~~552 MW 3(nominal ratings) of additional wind-powered generating facilities expected to be placed in service by the end of 2016.

The cost cap ensures that as long as total costs are below the cap, ~~nitrogen~~the ~~oxides~~investment ~~and~~will ~~particulate~~be ~~matter~~deemed ~~emissions~~prudent in any future Iowa rate proceeding. MidAmerican Energy has requested IUB approval by the end of the third quarter of 2015.

• Remaining costs primarily relate to routine expenditures for transmission, distribution, generation and other infrastructure needed to serve existing and expected demand.

In October 2014, MidAmerican Energy filed with the IUB an application for ratemaking principles related to the construction of up to 162 MW (nominal ratings) of additional wind-powered generating facilities expected to be placed in service by the end of 2015. The filing, which is subject to IUB approval, establishes a cost cap of $279 million, including AFUDC, and provides for a fixed rate of return on equity of 11.75% over the proposed 30-year useful lives of those facilities in any future Iowa rate proceeding. The cost cap ensures that as long as total costs are below the cap, the investment will be deemed prudent in any future Iowa rate proceeding. MidAmerican Energy has requested IUB approval in early 2015.

Contractual Obligations

As of ~~September~~June 30, ~~2014~~2015, there have been no material changes outside the normal course of business in MidAmerican Energy's and MidAmerican Funding's contractual obligations from the information provided in Item 7 of their Annual Report on Form 10‑K for the year ended December 31, ~~2013, except for the following items. As discussed in "Financing Activities" above, MidAmerican Energy issued $850 million of first mortgage bonds in April~~ 2014 ~~and redeemed $350 million of senior notes in May 2014~~. In October 2014, MidAmerican Energy entered into a contract with Siemens Energy Inc. ("Siemens") for the servicing, maintenance and repair of a majority of MidAmerican Energy's wind turbines procured from Siemens, including turbines currently under construction and turbines currently under warranty once the coverage expires. MidAmerican Energy expects to have more than 950 Siemens wind turbines in service by the end of 2015 that will be covered by the contract through June 2024.

Regulatory Matters

In March 2014, the IUB issued an order approving, with modifications, a non-unanimous settlement agreement among MidAmerican Energy, the Iowa Office of Consumer Advocate and environmental parties. The IUB order allows MidAmerican Energy to increase its base rates over approximately three years and will result in equal annualized increases in revenues of $45 million, or 3.6% over 2012, effective August 2013 and again on January 1, 2015 and 2016, for a total annualized increase of $135 million when fully implemented. In addition to an increase in base rates, the order approves the implementation of two adjustment clauses. One clause relates to retail energy production costs such as fuel, fuel transportation and the impacts of the production tax credit. The second clause relates to certain electric transmission charges. The adjustment clauses provide for recovery of these costs from customers based on MidAmerican Energy's forecasted annual costs, with the variance between actual and forecasted costs to be recovered or credited in the following year. The order also equalizes rates among MidAmerican Energy's current three pricing zones over a ten-year period. Rate equalization adjustments are revenue-neutral for MidAmerican Energy. The parties to the settlement agreement also agree not to seek or support an increase or decrease in the final base rates to become effective prior to January 1, 2018, unless MidAmerican Energy projects its return on equity for 2015, 2016 or 2017 to be below 10%. The IUB order also approves a revenue sharing mechanism that shares with MidAmerican Energy's customers 80% of revenues related to equity returns above 11% and 100% of revenues related to equity returns above 14%. The customer portion of any sharing reduces rate base. In April 2014, a number of the industrial intervenors sought rehearing on certain issues in the IUB order. The IUB granted rehearing for the purpose of reconsideration and on July 10, 2014, issued an order on rehearing that affirmed all of the economic provisions of its March 2014 order. On July 31, 2014, the IUB issued an order authorizing MidAmerican Energy to implement the new base rates and adjustment clauses effective immediately.

In December 2013, MidAmerican Energy filed a request with the Illinois Commerce Commission ("ICC") for a $22 million, or 17%, annual increase in Illinois retail electric base rates. In addition to the increase in base rates, the filing contains a request for the creation of a new adjustment clause for recovery of certain electric transmission charges to be effective with the implementation of final approved rates. On November 7, 2014, the ICC issued an order approving a retail electric base rate increase for MidAmerican Energy's Illinois customers. The order authorizes MidAmerican Energy to increase rates by $16 million, or 10%, annually and to implement the new adjustment clause for the recovery of electric transmission charges. New rates and the adjustment clause are expected to go into effect by December 1, 2014.

Environmental Laws and Regulations

MidAmerican Energy is subject to federal, state and local laws and regulations regarding air and water quality, emissions performance standards, climate change, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact its current and future operations. In addition to imposing continuing compliance obligations, these laws and regulations provide regulators with the authority to levy substantial penalties for noncompliance including fines, injunctive relief and other sanctions. These laws and regulations are administered by the EPA and various state and local agencies. MidAmerican Energy believes it is in material compliance with all applicable laws and regulations, although many are subject to interpretation that may ultimately be resolved by the courts. Refer to "Liquidity and Capital Resources" for discussion of MidAmerican Energy's ~~forecasted~~forecast environmental-related capital expenditures. The discussion below contains material developments to those matters disclosed in Item 7 of MidAmerican Energy's and MidAmerican Funding's Annual Report on Form 10‑K for the year ended December 31, ~~2013~~2014.

Clean Air Act Regulations

~~The~~National ~~Clean~~Ambient Air ~~Act~~Quality is a federal law administered by the EPA that provides a framework for protecting and improving the nation's air quality and controlling sources of air emissions. The implementation of new standards is generally outlined in State Implementation Plans ("SIPs"), which are a collection of regulations, programs and policies to be followed. SIPs vary by state and are subject to public hearings and EPA approval. Some states may adopt additional or more stringent requirements than those implemented by the EPA.Standards

The Sierra Club filed a lawsuit against the EPA in August 2013 with respect to the one-hour sulfur dioxide standards and its failure to make certain attainment designations in a timely manner. In March 2015, the United States District Court for the Northern District of California ("Northern District of California") accepted as an enforceable order an agreement between the EPA and Sierra Club to resolve litigation concerning the deadline for completing the designations. The Northern District of California's order directed the EPA to complete designations in three phases: the first phase by July 2, 2016; the second phase by December 31, 2017; and the final phase by December 31, 2020. The first phase of the designations require the EPA to designate two groups of areas: 1) areas that have newly monitored violations of the 2020 sulfur dioxide standard; and 2) areas that contain any stationary source that, according to the EPA's data, either emitted more than 16,000 tons of sulfur dioxide in 2012 or emitted more than 2,600 tons of sulfur dioxide and had an emission rate of at least 0.45 lbs/sulfur dioxide per million British thermal unit in 2012 and, as of March 2, 2015, had not been announced for retirement. MidAmerican Energy's George Neal Unit 4 and the Ottumwa Generating Station (in which MidAmerican Energy has a majority ownership interest in, but does not operate), are included as units subject to the first phase of the designations, having emitted more than 2,600 tons of sulfur dioxide and having an emission rate of at least 0.45 lbs/sulfur dioxide per million British thermal unit in 2012. States may submit to the EPA updated recommendations and supporting information for the EPA to consider in making its determinations and Iowa intends to submit such updated and supporting information by the specified deadline of September 18, 2015. The EPA intends to promulgate final sulfur dioxide area designations no later than July 2, 2016.

~~MidAmerican~~ Energy plans to retire four coal-fueled generating units between 2015 and 2016 as the least-cost alternative to comply with MATS. These units are Walter Scott, Jr. Energy Center Units 1 and 2, and George Neal Energy Center Units 1 and 2. These units produced 2.0 million MWh of electricity, or 7% of MidAmerican Energy's owned generation production, during 2013. A fifth unit, Riverside Generating Station, will be limited to natural gas combustion by March 31, 2015.37

Incremental costs to install and maintain emissions control equipment at MidAmerican Energy's coal-fueled generating facilities and any requirement to shut down what have traditionally been low cost coal-fueled generating facilities will likely increase the cost of providing service to customers. In addition, numerous lawsuits were filed against the MATS in the D.C. Circuit. In April 2014, the D.C. Circuit upheld the MATS requirements.

Clean Air Interstate Rule, Clean Air Transport Rule and Cross-State Air Pollution Rule

The EPA promulgated the CAIR in March 2005 to reduce emissions of nitrogen oxides and sulfur dioxide, precursors of ozone and particulate matter, from down-wind sources. The CAIR required states in the eastern United States, including Iowa, to reduce emissions by implementing a plan based on a market-based cap-and-trade system, emissions reductions, or both. The CAIR created separate trading programs for nitrogen oxides and sulfur dioxide emissions credits. The nitrogen oxides and sulfur dioxide emissions reductions were planned to be accomplished in two phases, in 2009-2010 and 2015.

In July 2008, a three-judge panel of the D.C. Circuit issued a unanimous decision vacating the CAIR. In December 2008, the D.C. Circuit issued an opinion remanding, without vacating, the CAIR back to the EPA to conduct proceedings to fix the flaws in CAIR consistent with the D.C. Circuit's July 2008 ruling. In response to the court's ruling on CAIR, in July 2010, the EPA proposed the Clean Air Transport Rule ("Transport Rule"), which required electric generating units in 31 states and the District of Columbia to reduce emissions of nitrogen oxides and sulfur dioxide on a state-by-state basis in accordance with each state's modeled contribution to nonattainment of the ozone and fine particulate standards in downwind states.

In July 2011, the EPA issued the final Transport Rule, renamed the Cross-State Air Pollution Rule ("CSAPR"), to address interstate transport of sulfur dioxide and nitrogen oxides emissions in 27 eastern and Midwestern states. Upon full implementation in 2014, the CSAPR would have reduced total sulfur dioxide emissions by 73% and nitrogen oxides emissions by 54% at electric generating facilities in the 27-state region as compared to 2005 levels.

In December 2011, the D.C. Circuit issued a stay on the implementation of the CSAPR pending consideration of several petitions for review before the court, which were ultimately decided in August 2012, when the D.C. Circuit vacated the CSAPR in a 2-1 decision after it determined that the CSAPR exceeded the EPA's statutory authority. In a petition filed in October 2012, the EPA sought a full review of the CSAPR ruling by the entire D.C. Circuit. In January 2013, the D.C. Circuit denied the request. The case was appealed to the United States Supreme Court where oral arguments were heard in December 2013. The United States Supreme Court issued its decision April 29, 2014, upholding the 2011 CSAPR and reversing the D.C. Circuit's ruling, concluding that the EPA's allocation of emissions reductions in upwind states permissibly considered the cost-effectiveness of achieving downwind attainment and that the EPA has authority under the Clean Air Act to impose federal implementation plans immediately after disapproving state implementation plans. The United States Supreme Court remanded the case to the D.C. Circuit for further action. The D.C. Circuit's previous stay of the rule was lifted in October 2014 and the first phase of the rule may be implemented as early as January 2015.

MidAmerican Energy has installed emissions controls at some of its coal-fueled generating facilities to comply with the CSAPR and may purchase emissions allowances to meet a portion of its compliance obligations. The cost of these allowances is subject to market conditions at the time of purchase and historically has not been material. The full impact of the CSAPR cannot be determined until the rule is fully implemented. However, MidAmerican Energy believes that the controls installed to date are consistent with the reductions to be achieved from implementation of such a rule.

MidAmerican Energy operates natural gas-fueled generating facilities in Iowa, which are subject to the CSAPR. However, the provisions are not anticipated to have a material impact on MidAmerican Energy.

Climate Change

InGHG ~~June 2014,~~Performance the EPA released proposed regulations to address greenhouse gas emissions from existing fossil-fueled generating facilities, referred to as the Clean Power Plan, under Section 111(d) of the Clean Air Act. The EPA's proposal calculated state-specific emission rate targets to be achieved based on four building blocks that it determined were the "Best System of Emission Reduction." The four building blocks include: (a) a 6% heat rate improvement from coal-fueled generating facilities; (b) increased utilization of existing combined-cycle natural gas-fueled generating facilities to 70%; (c) increased deployment of renewable and non-carbon generating resources; and (d) increased energy efficiency. Under the EPA's proposal, states may utilize any measure to achieve the specified emission reduction goals, with an initial implementation period of 2020-2029 and the final goal to be achieved by 2030. When fully implemented, the proposal is expected to reduce carbon dioxide emissions in the power sector to 30% below 2005 levels by 2030. The EPA is taking comment on its proposal until December 1, 2014, and is scheduled to issue final rules in June 2015. States are required to submit implementation plans by June 2016, but they may request an extension to June 2017, or June 2018 if they plan to participate in a regional compliance program. The impacts of the proposal on MidAmerican Energy cannot be determined until the EPA finalizes the proposal and the states develop their implementation plans. MidAmerican Energy has historically pursued cost-effective projects, including plant efficiency improvements, increased diversification of its generating fleet to include deployment of renewable and lower carbon generating resources, and advancement of customer energy efficiency programs.Standards

Under 40the Clean Air Act, the EPA may establish emissions standards that reflect the degree of emissions reductions achievable through the best technology that has been demonstrated, taking into consideration the cost of achieving those reductions and any non-air quality health and environmental impact and energy requirements. The EPA entered into a settlement agreement with a number of parties, including certain state governments and environmental groups, in December 2010 to promulgate emissions standards covering GHG. In April 2012, the EPA proposed new source performance standards for new fossil-fueled generating facilities that would limit emissions of carbon dioxide to 1,000 pounds per MWh. As part of his Climate Action Plan, President Obama announced a national climate change strategy and issued a presidential memorandum requiring the EPA to issue a re-proposed GHG new source performance standard for fossil-fueled generating facilities by September 2013. The September 2013 GHG new source performance standards released by the EPA set different standards for coal-fueled and natural gas-fueled generating facilities. The proposed standard for natural gas-fueled generating facilities considered the size of the unit and the electricity sent to the grid from the unit. The proposed standards were published in the Federal Register January 8, 2014, and the public comment period closed in May 2014. On August 3, 2015, the EPA issued the final new source performance standards, establishing a standard of 1,000 pounds of carbon dioxide per MWh for large natural gas-fueled generating facilities and 1,400 pounds of carbon dioxide per MWh for new coal-fueled generating facilities with the "Best System of Emission Reduction" for coal-fueled generating facilities reflecting highly efficient supercritical pulverized coal facilities with partial carbon capture and sequestration or integrated gasification combined-cycle units that are co-fired with natural gas or pre-combustion slipstream capture of carbon dioxide. Any new fossil-fueled generating facilities constructed by MidAmerican Energy will be required to meet the GHG new source performance standards.

~~Water~~In ~~Quality~~June 2014, ~~Standards~~the EPA released proposed regulations to address GHG emissions from existing fossil-fueled generating facilities, referred to as the Clean Power Plan, under Section 111(d) of the Clean Air Act. The EPA's proposal calculated state-specific emission rate targets to be achieved based on four building blocks that it determined were the "Best System of Emission Reduction." The four building blocks include: (a) a 6% heat rate improvement from coal-fueled generating facilities; (b) increased utilization of existing combined-cycle natural gas-fueled generating facilities to 70%; (c) increased deployment of renewable and non-carbon generating resources; and (d) increased energy efficiency. Under this proposal, states could have utilized any measure to achieve the specified emission reduction goals, with an initial implementation period of 2020-2029 and the final goal to be achieved by 2030. When fully implemented, the proposal was expected to reduce carbon dioxide emissions in the power sector to 30% below 2005 levels by 2030. The final Clean Power Plan was released August 3, 2015 and changed the methodology upon which the Best System of Emission Reduction is based to include: (a) heat rate improvements; (b) increased utilization of existing combined-cycle natural gas-fueled generating facilities; and (c) increased deployment of new and incremental non-carbon generation placed in-service after 2012. The EPA also changed the compliance period to begin in 2022, with three interim periods of compliance and with the final goal to be achieved by 2030. Based on changes to the state emission reduction targets, which are now all between 771 pounds per MWh and 1,305 pounds per MWh, the Clean Power Plan, when fully implemented, is expected to reduce carbon dioxide emissions in the power sector to 32% below 2005 levels by 2030. The EPA also released on August 3, 2015, a draft federal plan as an option or backstop for states to utilize in the event they do not submit approvable state plans. The draft federal plan is expected to be open for a 90-day public comment period after publication in the Federal Register. States are required to submit initial implementation plans by September 2016, and may request an extension to September 2018. The impacts of the final rule or the federal plan on MidAmerican Energy cannot be determined until the states develop their implementation plans or the federal plan is finalized. MidAmerican Energy has historically pursued cost-effective projects, including plant efficiency improvements, increased diversification of its generating fleet to include deployment of renewable and lower carbon generating resources, and advancement of customer energy efficiency programs.

The ~~federal~~GHG ~~Water~~rules ~~Pollution Control Act ("Clean Water Act") establishes the framework for maintaining~~ and ~~improving~~MidAmerican ~~water~~Energy's ~~quality~~compliance inrequirements ~~the~~are ~~United~~subject ~~States through a program that regulates, among other things, discharges~~ to ~~and~~potential ~~withdrawals~~outcomes from ~~waterways.~~proceedings ~~The~~and ~~Clean~~litigation ~~Water~~challenging ~~Act requires that cooling water intake structures reflect~~ the "best technology available for minimizing adverse environmental impact" to aquatic organisms. In July 2004, the EPA established significant new technology-based performance standards for existing electricity generating facilities that take in more than 50 million gallons of water per day. These rules ~~were aimed at minimizing the adverse environmental impacts of cooling water intake structures by reducing the number of aquatic organisms lost as a result of water withdrawals~~. In response to a legal challenge to the rule, in January 2007, the United States Court of Appeals for the Second Circuit ("Second Circuit") remanded almost all aspects of the rule to the EPA, without addressing whether companies with cooling water intake structures were required to comply with these requirements. On appeal from the Second Circuit, in April 2009, the United States Supreme Court ruled that the EPA permissibly relied on a cost-benefit analysis in setting the national performance standards regarding "best technology available for minimizing adverse environmental impact" at cooling water intake structures and in providing for cost-benefit variances from those standards as part of the §316(b) Clean Water Act Phase II regulations. The United States Supreme Court remanded the case back to the Second Circuit to conduct further proceedings consistent with its opinion.

InCoal ~~March~~Combustion ~~2011,~~Byproduct the EPA released a proposed rule under §316(b) of the Clean Water Act to regulate cooling water intakes at existing facilities. The proposed rule establishes requirements for all power generating facilities that withdraw more than two million gallons per day, based on total design intake capacity, of water from waters of the United States and use at least 25% of the withdrawn water exclusively for cooling purposes. All of MidAmerican Energy's coal-fueled generating facilities, except Louisa, Ottumwa and Walter Scott, Jr. Unit 4, which have water cooling towers, withdraw more than two million gallons per day of water from waters of the United States for once-through cooling applications. The proposed rule includes impingement (i.e., when fish and other organisms are trapped against screens when water is drawn into a facility's cooling system) mortality standards to be met through average impingement mortality or intake velocity design criteria and entrainment (i.e., when organisms are drawn into the facility) standards to be determined on a case-by-case basis. The standards are required to be met as soon as possible after the effective date of the final rule, but no later than eight years thereafter. While the rule was required to be finalized by the EPA by July 2012, the deadline for finalizing the rule was extended to June 2013 and then again to January 2014. The final rule was released May 19, 2014, and allows facilities to choose one of seven options to reduce fish impingement. Facilities that withdraw at least 125 million gallons of water per day must conduct studies to help their permitting authority determine what site-specific controls, if any, would be required to reduce entrainment of aquatic organisms. MidAmerican Energy is assessing the options for compliance at its generating facilities impacted by the final rule and will complete impingement and entrainment studies. The costs of compliance with the cooling water intake structure rule cannot be determined until the prescribed studies are conducted. In the event that MidAmerican Energy's existing intake structures require modification, the costs are not anticipated to be significant to its financial statements.Disposal

In April 2014, the EPA and the United States Army Corps of Engineers issued a joint proposal to address "Waters of the United States" to clarify protection under the Clean Water Act for streams and wetlands. The proposed rule comes as a result of United States Supreme Court decisions in 2001 and 2006 that created confusion regarding jurisdictional waters that were subject to permitting under either nationwide or individual permitting requirements. As currently proposed, a variety of projects that otherwise would have qualified for streamlined permitting processes under nationwide or regional general permits will be required to undergo more lengthy and costly individual permit procedures based on an extension of waters that will be deemed jurisdictional. The public comment period has been extended on the proposal to November 14, 2014. Until the rule is finalized, MidAmerican Energy cannot determine whether projects that include construction and demolition will face more complex permitting issues, higher costs or increased requirements for compensatory mitigation.38

As 41defined by the final rule, MidAmerican Energy owns or operates seven surface impoundments and four landfills that contain coal combustion byproducts. MidAmerican Energy continues to assess the requirements of the final rule to determine required compliance activities and the associated costs.

Collateral and Contingent Features

Debt securities of MidAmerican Energy are rated by credit rating agencies. Assigned credit ratings are based on each rating agency's assessment of MidAmerican Energy's ability to, in general, meet the obligations of its issued debt securities. 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 ~~September~~June 30, ~~2014~~2015, MidAmerican Energy's credit ratings for its senior secured debt and its issuer credit ratings for senior unsecured debt from the three recognized credit rating agencies were investment grade.

MidAmerican Funding and MidAmerican Energy have no credit rating downgrade triggers that would accelerate the maturity dates of its outstanding debt, and a change in ratings is not an event of default under the applicable debt instruments. MidAmerican Energy's unsecured revolving credit facilities do not require the maintenance of a minimum credit rating level in order to draw upon ~~its~~their availability. However, commitment fees and interest rates under the credit facilities are tied to credit ratings and increase or decrease when the ratings change. A ratings downgrade could also increase the future cost of commercial paper, short- and long-term debt issuances or new credit facilities.

In accordance with industry practice, certain wholesale agreements, including derivative contracts, contain credit support provisions that in part base MidAmerican Energy's collateral requirements on its credit ratings for senior unsecured debt as reported by one or more of the three recognized credit rating agencies. These agreements may either specifically provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features") or provide the right for counterparties to demand "adequate assurance," or in some cases terminate the contract, in the event of a material adverse change in MidAmerican Energy's creditworthiness. These rights can vary by contract and by counterparty. If all credit-risk-related contingent features or adequate assurance provisions for these agreements had been triggered as of ~~September~~June 30, ~~2014~~2015, MidAmerican Energy would have been required to post $~~132~~203 million of additional collateral. MidAmerican Energy's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation, or other factors. Refer to Note 76 of Notes to Financial Statements in Item 1 of this Form 10-Q for a discussion of MidAmerican Energy's collateral requirements specific to its derivative contracts.

New Accounting Pronouncements

For a discussion of new accounting pronouncements affecting MidAmerican Energy and MidAmerican Funding, refer to Note 2 of Notes to Consolidated Financial Statements in Item 1 of this Form 10-Q.

Critical Accounting Estimates

Certain accounting measurements require management to make estimates and judgments concerning transactions that will be settled several years in the future. Amounts recognized on the ~~Consolidated~~ Financial Statements based on such estimates involve numerous assumptions subject to varying and potentially significant degrees of judgment and uncertainty and will likely change in the future as additional information becomes available. Estimates are used for, but not limited to, the accounting for the effects of certain types of regulation, derivatives, impairment of goodwill and long-lived assets, pension and other postretirement benefits, income taxes and revenue recognition - unbilled revenue. For additional discussion of MidAmerican Energy's and MidAmerican Funding's critical accounting estimates, see Item 7 of their Annual Report on Form 10-K for the year ended December 31, ~~2013~~2014. There have been no significant changes in MidAmerican Energy's and MidAmerican Funding's assumptions regarding critical accounting estimates since December 31, ~~2013~~2014.

Item 4.	Controls and Procedures

At the end of the period covered by this Quarterly Report on Form 10-Q, the Company (MidAmerican Energy or MidAmerican Funding, as applicable) carried out an evaluation, under the supervision and with the participation of the Company's management, including the Chief Executive Officer (principal executive officer) and the Chief Financial Officer (principal financial officer), of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended).

There has been no change in the Company's internal control over financial reporting during the quarter ended ~~September~~June 30, ~~2014~~2015, that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.
