Item 7.01  Regulation FD Disclosure.

     As previously disclosed by MidAmerican Energy Holdings Company (the
"Company"), on May 23, 2005, the Company entered into a Stock Purchase
Agreement, as amended on March 21, 2006 (the "Stock Purchase Agreement") with
Scottish Power plc and its wholly-owned subsidiary, PacifiCorp Holdings, Inc.
("PHI"), pursuant to which the Company acquired 100% of the common stock of
PHI's direct subsidiary, PacifiCorp, for a cash purchase price of approximately
$5.1 billion (the "PacifiCorp Acquisition") on March 21, 2006.

     Also, as previously disclosed by the Company, in connection with the
PacifiCorp Acquisition, immediately prior to the closing thereof on March 21,
2006, Berkshire Hathaway Inc. ("Berkshire Hathaway"), the Company's majority
shareholder, invested approximately $5.07 billion and certain other of the
Company's existing shareholders and related companies invested approximately
$35.5 million in the Company's common stock in order to provide equity funding
for that acquisition (the "New Equity Investment"). Berkshire Hathaway has
granted the Company the right to repurchase up to $1.7 billion of the Company's
common stock issued to Berkshire Hathaway as part of the New Equity Investment
at any time prior to June 30, 2006 at the same price at which such stock was
issued.

     On March 17, 2006, the Company disclosed that, on such date, it had
commenced an offering of $3.25 billion in aggregate principal amount of
unsecured senior bonds due 2036 (the "Bonds"). On March 21, 2006, the Company
entered into a purchase agreement (the "Bond Purchase Agreement") with the
initial purchasers of the Bonds. Attached as an exhibit to the Bond Purchase
Agreement is a term sheet (the "Pricing Term Sheet") reflecting, among other
things, the pricing terms of the Bonds, as well as certain additional
information not contained or addressed in the confidential preliminary offering
memorandum, dated March 17, 2006 (the "Preliminary Offering Memorandum"),
prepared and distributed by the Company to qualified potential offerees of the
Bonds. The Pricing Term Sheet may contain certain material non-public
information relating to price of the Bonds, the scheduled closing of each of the
PacifiCorp Acquisition and the purchase and sale of the Bonds, and the effect of
the reduction of the offering amount from $3.25 billion to $1.7 billion on the
pro forma financial statements and other information previously disclosed by the
Company.

     As set forth in the Pricing Term Sheet, the purchase and sale of the Bonds
is scheduled to occur on March 24, 2006. In addition, the Company has determined
to issue $1.7 billion (rather than $3.25 billion) in aggregate principal amount
of the Bonds. The Bonds were issued at an offering price of 99.957% and will
accrue interest at a rate of 6.125% of per annum, as agreed upon by the Company
and the initial purchasers of the Bonds, and will mature on April 1, 2036. As a
result of the reduction in size of the Bond offering from $3.25 billion to $1.7
billion, the Company will not pre-fund its $1.55 billion of senior notes
maturing in 2007 and 2008, as contemplated by the Preliminary Offering
Memorandum. The principal pro forma effects of this reduction in the size of the
offering are that the Company's unaudited pro forma condensed combined
consolidated total assets and total liabilities, respectively, as of December
31, 2005, will be approximately $34,368.3 million (a reduction of approximately
$1,569.0 million from the pro forma information contained in the Preliminary
Offering Memorandum) and $27,339.2 million (a reduction of $1,569.0 million from
such pro forma information), respectively, and its unaudited pro forma condensed
combined consolidated income from continuing operations for the twelve month
period ended December 31, 2005 will be approximately

                                       2



$796.1 million (an increase of approximately $7.4 million from the pro forma
information contained in the Preliminary Offering Memorandum), as a result of
lower interest expense partially offset by lower interest income, net of taxes.

     The Company intends to use the entire gross proceeds from the sale of the
Bonds to repurchase from Berkshire Hathaway a portion of the Company's common
stock issued to it as part of the New Equity Investment.

     This Current Report on Form 8-K and the statements contained herein
(including the exhibits hereto) do not, and shall not be deemed to, constitute
an offer to sell or buy or a solicitation of an offer to sell or buy any
securities of the Company (including, without limitation, the Bonds). The Bonds
have not been registered under the Securities Act of 1933 as amended (the
"Securities Act"), or any state securities laws, and unless so registered, may
not be offered or sold except pursuant to an exemption from the registration
requirements of the Securities Act and applicable state laws. The Bonds are
being sold only to "Qualified Institutional Buyers" under Rule 144A and to
non-U. S. persons in offshore transactions under Regulation S. Any offers of the
Bonds will be made exclusively by means of a private offering memorandum
(including the Preliminary Offering Memorandum).

business or investment considerations that may be disclosed from time to time in
our SEC filings or in other publicly disseminated written documents.

     Further details of the potential risks and uncertainties affecting the
Company are described in the "Risk Factors" contained in Exhibit 20.1 to the

as a result of new information, future events or otherwise. The foregoing review
of factors should not be construed as exclusive.
