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 March 31, 2015, and the related statements of operations, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2015 and 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, 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 February 27, 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, 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 March 31, 2015, and for the three-month periods ended March 31, 2015 and 2014. The results of operations for the three-month period ended March 31, 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, 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 three-month period ended March 31, 2015.


(2)	New Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-03, which amends FASB Accounting Standards Codification ("ASC") Subtopic 835-30, "Interest - Imputation of Interest." The amendments in this guidance require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability instead of as an asset. This guidance is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. This guidance must be adopted retrospectively, wherein the balance sheet of each period presented should be adjusted to reflect the new 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. This guidance is effective for interim and annual reporting periods beginning after December 15, 2016. Early application is not permitted. 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.


(3)	Components of Accumulated Other Comprehensive Income (Loss), Net

The following table shows the change in accumulated other comprehensive income (loss), net ("AOCI") by each component of other comprehensive income, net of applicable income taxes (in millions):



	Unrealized			Unrealized			Accumulated
	Losses on			(Losses) Gains			Other
	Available-For-Sale			on Cash Flow			Comprehensive
	Securities			Hedges			(Loss) Income, Net

Balance, December 31, 2013	$	(4	)	$	(7	)	$	(11	)
Other comprehensive income	1			14			15
Balance, March 31, 2014	$	(3	)	$	7		$	4

Balance, December 31, 2014	$	(3	)	$	(20	)	$	(23	)
Other comprehensive income	—			2			2
Balance, March 31, 2015	$	(3	)	$	(18	)	$	(21	)

For information regarding cash flow hedge reclassifications from AOCI to net income in their entirety, refer to Note 6.


(4)	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:



	Three-Month Periods
	Ended March 31,
	2015		2014

Federal statutory income tax rate	35	%	35	%
Income tax credits	(57	)	(54	)
State income tax, net of federal income tax benefit	4		2
Effects of ratemaking	(10	)	(5	)
Other, net	(1	)	(1	)
Effective income tax rate	(29	)%	(23	)%

Income tax credits relate primarily to production tax credits earned 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. For the three-month periods ended March 31, 2015 and 2014, MidAmerican Energy did not have any cash transactions for income taxes with BHE.


(5)	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):



	Three-Month Periods
	Ended March 31,
	2015			2014
Pension:
Service cost	$	3		$	3
Interest cost	8			9
Expected return on plan assets	(11		)	(11		)
Net amortization	—			1
Net periodic benefit cost	$	—		$	2

Other postretirement:
Service cost	$	2		$	1
Interest cost	2			2
Expected return on plan assets	(4		)	(3		)
Net amortization	(1		)	(1		)
Net periodic benefit cost (benefit)	$	(1	)	$	(1	)

Employer contributions to the pension and other postretirement benefit plans are expected to be $8 million and $1 million, respectively, during 2015. As of March 31, 2015, $2 million and $- million of contributions had been made to the pension and other postretirement benefit plans, respectively.


(6)	Risk Management and Hedging 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 7 for additional information on derivative contracts.

The following table, which reflects master netting arrangements and excludes contracts that have been designated as normal under the normal purchases or normal sales exception afforded by GAAP, summarizes the fair value of MidAmerican Energy's derivative contracts, on a gross basis, and reconciles those amounts to the amounts presented on a net basis on the Balance Sheets (in millions):

Designated as Hedging Contracts

MidAmerican Energy uses commodity derivative contracts accounted for as cash flow hedges to hedge electricity and natural gas commodity prices for delivery to nonregulated customers. The following table reconciles the beginning and ending balances of MidAmerican Energy's accumulated other comprehensive (income) loss (pre-tax) and summarizes pre-tax gains and losses on commodity derivative contracts designated and qualifying as cash flow hedges recognized in other comprehensive income ("OCI"), as well as amounts reclassified to earnings (in millions):

Ending balance	$	30		$	(13	)

Realized gains and losses on hedges and hedge ineffectiveness are recognized in income as nonregulated operating revenue or nonregulated cost of sales depending upon the nature of the item being hedged. For the three-month periods ended March 31, 2015 and 2014, hedge ineffectiveness was a pre-tax gain of $1 million and $- million, respectively. As of March 31, 2015, MidAmerican Energy had cash flow hedges with expiration dates extending through December 2019, and $16 million of pre-tax net unrealized losses are forecasted to be reclassified from AOCI into earnings over the next twelve months as contracts settle.

Credit Risk

MidAmerican Energy is exposed to counterparty credit risk associated with wholesale energy supply and marketing activities with other utilities, energy marketing companies, financial institutions and other market participants. Additionally, MidAmerican Energy participates in the regional transmission organization ("RTO") markets and has indirect credit exposure related to other participants, although RTO credit policies are designed to limit exposure to credit losses from individual participants. Credit risk may be concentrated to the extent MidAmerican Energy's counterparties have similar economic, industry or other characteristics and due to direct or indirect relationships among the counterparties. Before entering into a transaction, MidAmerican Energy analyzes the financial condition of each significant wholesale counterparty, 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 further mitigate wholesale counterparty credit risk, 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. If required, MidAmerican Energy exercises rights under these arrangements, including calling on the counterparty's credit support arrangement.

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 March 31, 2015, MidAmerican Energy's credit ratings from the three recognized credit rating agencies were investment grade.

The aggregate fair value of MidAmerican Energy's derivative contracts in liability positions with specific credit-risk-related contingent features totaled $39 million and $52 million as of March 31, 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 March 31, 2015 and December 31, 2014, MidAmerican Energy would have been required to post $31 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.


(7)	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.

The following table presents MidAmerican Energy's assets and liabilities recognized on the Balance Sheets and measured at fair value on a recurring basis (in millions):

(2)	Amounts are included in cash and cash equivalents and investments and nonregulated property, net on the Balance Sheets. The fair value of these money market mutual funds approximates cost.

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 6 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 accounted for as available-for-sale securities. 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.

The following table reconciles the beginning and ending balances of MidAmerican Energy's assets and liabilities measured at fair value on a recurring basis using significant Level 3 inputs (in millions):

For commodity derivatives held as of March 31, 2015 and 2014, net unrealized gains (losses) included in earnings for the three-month periods ended March 31, 2015 and 2014, totaled $3 million and $(1) million, respectively.

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):

Environmental Laws and Regulations


(9)	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.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)


(1)	General

MidAmerican Funding, LLC ("MidAmerican Funding") 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"). MidAmerican Funding's direct, wholly owned subsidiary is MHC Inc. ("MHC"), which constitutes substantially all of MidAmerican Funding's assets, liabilities and business activities except those related to MidAmerican Funding's long-term debt securities. MHC conducts no business other than the ownership of its subsidiaries and related corporate services. MHC's principal subsidiary is MidAmerican Energy Company ("MidAmerican Energy"), a public utility with electric and natural gas operations. Direct, wholly owned nonregulated subsidiaries of MHC are Midwest Capital Group, Inc. and MEC Construction Services Co.

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 March 31, 2015, and for the three-month periods ended March 31, 2015 and 2014. The results of operations for the three-month period ended March 31, 2015, are not necessarily indicative of the results to be expected for the full year.

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, 2014, describes the most significant accounting policies used in the preparation of the unaudited Consolidated Financial Statements. There have been no significant changes in MidAmerican Funding's assumptions regarding significant accounting estimates and policies during the three-month period ended March 31, 2015.

Other, net	(1	)	(1	)
Effective income tax rate	(22	)%	(24	)%

Berkshire Hathaway includes BHE and subsidiaries in its United States federal income tax return. Consistent with established regulatory practice, MidAmerican Funding's and MidAmerican Energy's provisions for income taxes have been computed on a stand-alone basis, and substantially all of their currently payable or receivable income taxes are remitted to or received from BHE. For the three-month periods ended March 31, 2015 and 2014, MidAmerican Funding did not have any cash transactions for income taxes with BHE.


(5)	Employee Benefit Plans

Refer to Note 5 of MidAmerican Energy's Notes to Financial Statements.


(6)	Risk Management and Hedging Activities

Refer to Note 6 of MidAmerican Energy's Notes to Financial Statements.


(7)	Fair Value Measurements

Refer to Note 7 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):



	As of March 31, 2015				As of December 31, 2014
	Carrying Value		Fair Value		Carrying Value		Fair Value

Long-term debt	$	4,385	$	5,094	$	4,381	$	5,012


(8)	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 8 of MidAmerican Energy's Notes to Financial Statements.

(9) 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.

Results of Operations for the First Quarter of 2015 and 2014

Overview

MidAmerican Energy -

MidAmerican Energy's net income for the first quarter of 2015 was $94 million, a decrease of $63 million, or 40%, compared to 2014 due to changes in regulated electric retail rate structure in Iowa related to seasonal pricing, partially offset by higher retail rates, lower natural gas margins from colder than normal winter temperatures in 2014, greater depreciation and amortization expense from utility plant additions, a decrease in federal income tax benefits from lower recognized production tax credits, higher maintenance costs related to wind-powered generating facilities, higher interest on long-term debt primarily from the issuance of first mortgage bonds in April 2014, net of the effect of a related debt retirement in May 2014, and lower AFUDC, partially offset by higher electric transmission revenue from MidAmerican Energy's Multi-Value Projects ("MVPs").

MidAmerican Funding -

MidAmerican Funding's net income for the first quarter of 2015 was $99 million, a decrease of $56 million, or 36%, compared to 2014. In addition to the changes in MidAmerican Energy's earnings discussed above, MidAmerican Funding recognized an $8 million after-tax gain on the sale of an investment in a generating facility lease in the first quarter of 2015.

(2)	All or some of the renewable energy attributes associated with generation from these generating facilities may be: (a) used in future years to comply with renewable portfolio standards or other regulatory requirements or (b) sold to third parties in the form of renewable energy credits or other environmental commodities.

Electric gross margin for the first quarter of 2015 was unchanged compared to 2014 due to higher MVP transmission revenue of $5 million, lower wholesale gross margin of $4 million and lower retail gross margin of $1 million. MidAmerican Energy's MVP revenue is expected to increase as the projects are constructed over the next two years. Wholesale gross margin decreased due to a lower average margin per megawatt hour sold. Wholesale includes sales of electricity principally to markets operated by regional transmission organizations. Retail gross margin decreased due to $17 million from lower electric retail rates and $8 million from lower sales volumes for weather-sensitive customers in 2015 due to colder than normal winter temperatures in 2014, offset by $15 million from higher recoveries through adjustment clauses, including DSM, $6 million from lower generation costs for retail and $3 million primarily from greater industrial sales volumes and customer growth. The decrease in electric rates reflects changes in Iowa rate structure related to seasonal pricing that were effective with the implementation of final Iowa base rates in August 2014 and result in a greater differential between higher rates from June to September and lower rates in the remaining months, partially offset by higher retail rates of $45 million annually, effective January 2015, for the second step of the 2014 Iowa rate increase and $16 million annually in Illinois, effective December 2014.

Regulated Gas Gross Margin

A comparison of key operating results related to regulated gas gross margin is as follows:



	First Quarter
	2015		2014		Change
Gross margin (in millions):
Operating revenue	$	295	$	511	$	(216	)	(42)	%

Combined retail and wholesale average cost of natural gas per Dth sold	$	3.93	$	7.73	$	(3.80	)	(49)	%

Heating degree days	3,448		3,954		(506		)	(13)	%

Regulated gas gross margin for the first quarter of 2015 decreased $8 million compared to 2014 due to lower retail sales volumes in 2015 primarily as a result of colder than normal winter temperatures in 2014. 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. For the first quarter of 2015, MidAmerican Energy's combined retail and wholesale average per-unit cost of gas sold decreased 49%, resulting in a decrease of $194 million in gas revenue and cost of gas sold compared to 2014. Additionally, the decrease in total sales volumes compared to 2014 decreased revenue and cost of gas sold for the first quarter of 2014.

Regulated Operating Costs and Expenses

Other operating expenses of $117 million for the first quarter of 2015 increased $8 million compared to 2014 due to $10 million of higher DSM program costs, which are matched by increases in regulated electric and gas revenue and $2 million of higher transmission operations costs, partially offset by a decrease in pension and postretirement costs and other operations costs.

Maintenance expense of $49 million for the first quarter of 2015 increased $5 million compared to 2014 due to higher wind-powered generating facility maintenance costs.

Depreciation and amortization expense of $100 million for the first quarter of 2015 increased $15 million compared to 2014 due to utility plant additions, including 511 MW (nominal ratings) of wind-powered generating facilities.

Nonregulated Gross Margin

MidAmerican Energy -



	First Quarter
	2015		2014		Change
Gross margin (in millions):
Nonregulated operating revenue	$	225	$	264	$	(39	)	(15	)%
Nonregulated cost of sales	212		241		(29		)	(12	)
Nonregulated gross margin	$	13	$	23	$	(10	)	(43	)

Nonregulated electric sales (GWh)	2,474		2,234		240			11	%

Nonregulated gas sales (000's Dth)	10,272		11,390		(1,118		)	(10	)%

For the first quarter of 2015 compared to 2014, nonregulated operating revenue and cost of sales decreased due to lower prices and per-unit costs, respectively, on lower gas volumes, partially offset by an increase in nonregulated electric volumes. Nonregulated gross margin decreased due to lower average margins per unit sold on nonregulated electric and 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.

Non-Operating Income

MidAmerican Energy -

Allowance for equity funds of $5 million for the first quarter of 2015 decreased $4 million compared to 2014 primarily due to lower construction work-in-progress balances related to the installation of emissions control equipment at a number of MidAmerican Energy's jointly owned generating facilities.

MidAmerican Funding -

MidAmerican Funding's other, net of $17 million for the first quarter of 2015 increased $12 million compared to 2014 primarily due to a $13 million pre-tax gain on the sale of an investment in a generating facility lease in 2015.

Fixed Charges

MidAmerican Energy -

Interest on long-term debt of $44 million for the first quarter of 2015 increased $4 million compared to 2014 due to higher interest expense from the issuance of first mortgage bonds totaling $850 million in April 2014, partially offset by a decrease in interest expense from the redemption of $350 million of 4.65% senior notes in May 2014.

Allowance for borrowed funds of $2 million for the first quarter of 2015 decreased $2 million compared to 2014 primarily due to lower construction work-in-progress balances related to the installation of emissions control equipment at a number of MidAmerican Energy's jointly owned generating facilities.

Income Tax Benefit

MidAmerican Energy -

MidAmerican Energy's income tax benefit was $21 million for the first quarter of 2015, a decrease of $8 million compared to $29 million for 2014, with an effective tax rate of (29)% for 2015 and (23)% for 2014. The decrease in income tax benefit for the first quarter of 2015 was due to a decrease in recognized production tax credits, partially offset by the impact of a lower pre-tax income.

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 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. Production tax credits recognized in the first quarter of 2015 were $41 million, or $27 million lower than the first quarter of 2014, while production tax credits earned in the first quarter of 2015 were $58 million, or $4 million higher than the first quarter of 2014 primarily due to wind-powered generation placed in service in late 2014. The difference between production tax credits recognized and earned of $17 million as of March 31, 2015 will be recorded in earnings over the remainder of 2015.

MidAmerican Funding -

MidAmerican Funding's income tax benefit was $18 million for the first quarter of 2015, a decrease of $12 million compared to $30 million for 2014, with an effective tax rate of (22)% for 2015 and (24)% for 2014. The change in the income tax benefit and effective tax rates was due principally 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 March 31, 2015, MidAmerican Energy's total net liquidity was $345 million consisting of $605 million of credit facilities reduced by $195 million of the credit facilities reserved to support MidAmerican Energy's variable-rate tax-exempt bond obligations and $65 million of short-term debt. As of March 31, 2015, MidAmerican Funding's total net liquidity was $350 million, including $1 million of additional cash and cash equivalents and MHC Inc.'s $4 million credit facility.

Operating Activities

MidAmerican Energy's net cash flows from operating activities for the three-month periods ended March 31, 2015 and 2014, were $206 million and $96 million, respectively. MidAmerican Funding's net cash flows from operating activities for the three-month periods ended March 31, 2015 and 2014, were $197 million and $92 million, respectively. The increases were predominantly due to the impact of receivables and payables, largely attributable to the fluctuation in the cost of natural gas, and lower collateral requirements related to derivative positions.

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 timing of the Act and MidAmerican Energy's income tax cash flows with BHE, MidAmerican Energy had a federal income tax receivable of $327 million as of March 31, 2015, which is expected to benefit cash flows from operations in 2015. The timing of MidAmerican Energy's income tax cash flows from period to period can be significantly affected by the estimated federal income tax payment methods and assumptions for each payment date.

Investing Activities

MidAmerican Energy's net cash flows from investing activities for the three-month periods ended March 31, 2015 and 2014, were $(250) million and $(177) million, respectively. MidAmerican Funding's net cash flows from investing activities for the three-month periods ended March 31, 2015 and 2014, were $(237) million and $(174) million, respectively. Net cash flows from investing activities consist almost entirely of utility construction expenditures, which increased for 2015 principally due to expenditures for the construction of wind-powered generating facilities and transmission MVPs. Purchases and proceeds related to available-for-sale securities primarily consist of activity within the Quad Cities Generating Station nuclear decommissioning trust.

Financing Activities

MidAmerican Energy's net cash flows from financing activities for the three-month periods ended March 31, 2015 and 2014 were $15 million and $- million, respectively. MidAmerican Funding's net cash flows from financing activities for the three-month periods ended March 31, 2015 and 2014, were $11 million and $2 million, respectively. In 2015, MidAmerican Energy received $15 million through its commercial paper program. MidAmerican Funding paid $4 million in 2015 and received $2 million in 2014 through its note payable with BHE.

Debt Authorizations and Related Matters

MidAmerican Energy has authority from the FERC to issue through June 30, 2016, commercial paper and bank notes aggregating $605 million at interest rates not to exceed the applicable London Interbank Offered Rate ("LIBOR") plus a spread of up to 400 basis points. MidAmerican Energy has a $600 million unsecured credit facility expiring in March 2018. MidAmerican Energy may request that the banks extend the credit facility up to two years. The credit facility, which supports MidAmerican Energy's commercial paper program and its variable-rate tax-exempt bond obligations and provides for the issuance of letters of credit, has a variable interest rate based on LIBOR or a base rate, at MidAmerican Energy's option, plus a spread that varies based on MidAmerican Energy's credit ratings for senior unsecured long-term debt securities. 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 March 31, 2017, long-term securities totaling up to $1.70 billion at interest rates not to exceed the applicable United States Treasury rate plus a spread of 175 basis points. MidAmerican Energy has 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 March 31, 2015, MidAmerican Energy's common equity ratio was 51% 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 forecast utility construction expenditures, which exclude amounts for non-cash equity AFUDC and other non-cash items, are approximately $1.5 billion for 2015 and include:


•	$799 million for the construction of 657 MW (nominal ratings) of wind-powered generating facilities expected to be placed in service in 2015, including 162 MW (nominal ratings) approved by the IUB in February 2015.


•	$168 million for transmission MVPs investments. MidAmerican 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 to MidAmerican Energy's transmission system, with remaining expenditures predominantly in 2015 and 2016.


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

In April 2015, MidAmerican Energy filed with the IUB an application for ratemaking principles related to the construction of up to 552 MW (nominal ratings) of additional wind-powered generating facilities expected to be placed in service by the end of 2016. The filing, which is subject to IUB approval, establishes a cost cap of $903 million, including AFUDC, and provides for a fixed rate of return on equity of 11.5% 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 by the end of the third quarter of 2015.

Contractual Obligations

As of March 31, 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, 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 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, 2014.

Clean Air Act Regulations

National Ambient Air Quality 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.

Mercury and Air Toxics Standards

Numerous lawsuits have been filed in the United States Court of Appeals for the District of Columbia Circuit ("D.C. Circuit") challenging the Mercury and Air Toxics Standards ("MATS"). In April 2014, the D.C. Circuit upheld the MATS requirements. In November 2014, the United States Supreme Court agreed to hear the MATS appeal on the limited issue of whether the EPA unreasonably refused to consider costs in determining whether it is appropriate to regulate hazardous air pollutants emitted by electric utilities. Oral argument in the case was held before the United States Supreme Court in March 2015, and a decision is expected by the end of June 2015. The outcome of the United States Supreme Court's decision is uncertain and until the court renders its decision or otherwise implements a stay of the MATS requirements, MidAmerican Energy is proceeding to fulfill its legal obligations to comply with the MATS, including retiring the Walter Scott, Jr. Energy Center Units 1 and 2 coal-fueled generating facilities and ceasing the utilization of coal at the Riverside Generating Station.

Coal Combustion Byproduct Disposal

In May 2010, the EPA released a proposed rule to regulate the management and disposal of coal combustion byproducts, presenting two alternatives to regulation under the Resource Conservation and Recovery Act ("RCRA"). The public comment period closed in November 2010. The final rule was released by the EPA on December 19, 2014, was published in the Federal Register on April 17, 2015 and will be effective on October 14, 2015. The final rule regulates coal combustion byproducts as non-hazardous waste under RCRA Subtitle D and establishes minimum nationwide standards for the disposal of coal combustion residuals. Under the final rule, surface impoundments and landfills utilized for coal combustion byproducts may need to be closed unless they can meet the more stringent regulatory requirements.

As defined by the final rule, MidAmerican Energy owns or operates seven surface impoundments and four landfills that contain coal combustion byproducts. MidAmerican Energy is assessing 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 March 31, 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 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 March 31, 2015, MidAmerican Energy would have been required to post $232 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 6 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 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, 2014. There have been no significant changes in MidAmerican Energy's and MidAmerican Funding's assumptions regarding critical accounting estimates since December 31, 2014.

There has been no change in the Company's internal control over financial reporting during the quarter ended March 31, 2015, that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.
