PERMIAN BASIN ROYALTY TRUST
 NOTES TO CONDENSED FINANCIAL STATEMENTS (UNAUDITED)
 1.
    
    BASIS OF ACCOUNTING
 The Permian Basin Royalty Trust (Trust) was established as of November 1, 1980. The net
overriding royalties conveyed to the Trust include: (1) a 75% net overriding royalty carved out
of Southland Royalty Companys fee mineral interests in the Waddell Ranch in Crane County, Texas
(the Waddell Ranch properties); and (2) a 95% net overriding royalty carved out of Southland
Royalty Companys major producing royalty interests in Texas (the Texas Royalty properties).
The net overriding royalty for the Texas Royalty properties is subject to the provisions of the
lease agreements under which such royalties were created. The financial statements of the Trust
are prepared on the following basis:
 
    
    Royalty income recorded for a month is the amount computed and paid to Bank of America,
N.A. (Trustee) as Trustee for the Trust by the interest owners: Burlington Resources Oil
& Gas Company LP (BROG), a subsidiary of ConocoPhillips for the Waddell Ranch properties
and Riverhill Energy Corporation (Riverhill Energy), formerly a wholly owned subsidiary
of Riverhill Capital Corporation (Riverhill Capital) and formerly an affiliate of Coastal
Management Corporation (CMC), for the Texas Royalty properties. Schlumberger Technology
Corporation (STC) currently conducts all field, technical and accounting operations on
behalf of BROG with regard to the Waddell Ranch properties. Riverhill Energy currently
conducts the accounting operations for the Texas Royalty properties. Royalty income
consists of the amounts received by the owners of the interest burdened by the net
overriding royalty interests (Royalties) from the sale of production less accrued
production costs, development and drilling costs, applicable taxes, operating charges, and
other costs and deductions multiplied by 75% in the case of the Waddell Ranch properties
and 95% in the case of the Texas Royalty properties.As was previously reported, in February 1997, BROG sold its interest in the Texas Royalty
properties to Riverhill Energy.The Trustee has been advised that in the first quarter of 1998, STC acquired all of the
shares of stock of Riverhill Capital. Prior to such acquisition by STC, CMC and Riverhill
Energy were wholly owned subsidiaries of Riverhill Capital. The Trustee has further been
advised that in connection with STCs acquisition of Riverhill Capital, the shareholders of
Riverhill Capital acquired ownership of all of the shares of stock of Riverhill Energy.
Thus, the ownership in the Texas Royalty properties referenced above remained in Riverhill
Energy, the stock ownership of which was acquired by the former shareholders of Riverhill
Capital.In 2007 the Bank of America private wealth management group officially became known as U.S.
Trust, Bank of America Private Wealth Management. The legal entity that serves as Trustee
of the Trust did not change, and references in this Form 10-Q to U.S.

##### Table of Contents



Trust, Bank of America
Private Wealth Management shall describe the legal entity Bank of America, N.A.
 
    
    Trust expenses recorded are based on liabilities paid and cash reserves established out
of cash received or borrowed funds for liabilities and contingencies.
    
    Distributions to Unit holders are recorded when declared by the Trustee.
    
    Royalty income is computed separately for each of the conveyances under which the
Royalties were conveyed to the Trust. If monthly costs exceed revenues for any conveyance
(excess costs), such excess costs cannot reduce royalty income from other conveyances,
but is carried forward with accrued interest to be recovered from future net proceeds of
that conveyance.
 The financial statements of the Trust differ from financial statements prepared in
accordance with accounting principles generally accepted in the United States of America
(GAAP) because revenues are not accrued in the month of production and certain cash
reserves may be established for contingencies which would not be accrued in financial
statements prepared in accordance with GAAP. Amortization of the Royalties calculated on a
unit-of-production basis is charged directly to trust corpus. This comprehensive basis of
accounting other than GAAP corresponds to the accounting permitted for royalty trusts by the
U.S. Securities and Exchange Commission as specified by Staff Accounting Bulletin Topic
12:E, Financial Statements of Royalty Trusts.

    FEDERAL INCOME TAXES
 For Federal income tax purposes, the Trust constitutes a fixed investment trust which is taxed
as a grantor trust. A grantor trust is not subject to tax at the trust level. The Unit holders
are considered to own the Trusts income and principal as though no trust were in existence.
The income of the Trust is deemed to have been received or accrued by each Unit holder at the
time such income is received or accrued by the Trust and not when distributed by the Trust.
 11




---



##### Table of Contents



The Royalties constitute economic interests in oil and gas properties for Federal income tax
purposes. Unit holders must report their share of the revenues from the Royalties as ordinary
income from oil and gas royalties and are entitled to claim depletion with respect to such
income.
 The Trust has on file technical advice memoranda confirming the tax treatment described above.
 The classification of the Trusts income for purposes of the passive loss rules may be important
to a Unit holder. Royalty income generally is treated as portfolio income and does not offset
passive losses.
 Some Trust Units are held by middlemen, as such term is broadly defined in U.S. Treasury
Regulations (and includes custodians, nominees, certain joint owners, and brokers holding an
interest for a custodian in street name, collectively referred to herein as middlemen).
Therefore, the Trustee considers the Trust to be a widely held fixed investment trust (WHFIT)
for U.S. federal income tax purposes. U.S. Trust, Bank of America Private Wealth Management,
901 Main Street, 17th Floor, Dallas, Texas 75202, telephone number (214) 209-2400, is the
representative of the Trust that will provide tax information in accordance with applicable U.S.
Treasury Regulations governing the information reporting requirements of the Trust as a WHFIT.
Tax information is also posted by the Trustee at www.pbt-permianbasintrust.com.
Notwithstanding the foregoing, the middlemen holding Trust Units on behalf of Unit holders, and
not the Trustee of the Trust, are solely responsible for complying with the information
reporting requirements under the U.S. Treasury Regulations with respect to such Trust Units,
including the issuance of IRS Forms 1099 and certain written tax statements. Unit holders whose
Trust Units are held by middlemen should consult with such middlemen regarding the information
that will be reported to them by the middlemen with respect to the Trust Units.
 Unit holders should consult their tax advisors regarding Trust tax compliance matters.
 3.
    
    STATE TAX CONSIDERATIONS
 All revenues from the Trust are from sources within Texas, which has no individual income tax.
However, Texas imposes a margin tax on generally all entity types providing limited liability
protection at a rate of 1% on gross revenues less certain deductions, as specifically set forth
in the Texas margin tax statute. Entities subject to tax generally include trusts unless
otherwise exempt. Trusts that receive at least 90% of their Federal gross income from
designated passive sources, including royalties from mineral properties and other non-operated
mineral interest income, and do not receive more than 10% of their income from operating an
active trade or business, generally are exempt from the Texas margin tax as passive entities.
The Trust should be exempt from Texas margin tax as a passive entity. Since the Trust should
be exempt from Texas margin tax at the Trust level as a passive entity, each Unit holder that is
considered a taxable entity under the Texas margin tax will generally be required to include its
portion of Trust revenues in its own Texas margin tax computation. This revenue is sourced to
Texas under provisions of the Texas Administrative Code that provide such income is sourced
according to the principal place of business of the Trust, which is Texas.

    SUBSEQUENT EVENTS
 Subsequent to June 30, 2009, the Trust declared a distribution of .074511 per unit on July 21,
2009 payable on August 14, 2009, to Unit holders of record on
July 31, 2009. Subsequent events have been evaluated through
August 10, 2009, the date
of issuance of these
condensed financial statements.
