      REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors and Stockholders
SEI HOLDINGS, INC.
(f/k/a CRT Holdings, Inc.)
(f/k/a USAS Digital, Inc.)
A Development Stage Enterprise
Jupiter, Florida

We have reviewed the accompanying balance sheets of SEI Holdings, Inc. (f/k/a
CRT Holdings, Inc.), (f/k/a USAS Digital, Inc.) a Development Stage Enterprise,
as of August 31, 2007, and the related statements of operations, for three month
periods ended August 31, 2007 and 2006 and Inception, December 8, 2003 through
August 31, 2007, the statement of changes in stockholders' equity from June 1,
2005 through August 31, 2007 and the statement of cash flows for the three month
periods ended August 31, 2007 and 2006 and Inception, December 8, 2003 through
August 31, 2007. These financial statements are the responsibility of the
company's management.

We conducted our review in accordance with the standards established by 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 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 review, we are not aware of any material modifications that should
be made to the accompanying interim financial statements for them to be in
conformity with U.S. generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

NOTE A - HISTORY AND DESCRIPTION OF BUSINESS

Pursuant to SEC Staff Legal Bulletin No. 4, eCom decided to spin off USAS
Digital into an independent company in the belief that the independent company,
with a distinct business, would be better able to obtain necessary funding and
develop their business plans.

On December 1, 2003, the Board of Directors of eCom eCom.com, Inc., approved
the spin-off of USAS Digital.

USAS Digital, Inc. (the "Company") was incorporated in the State of Florida on
December 8, 2003 as a wholly owned subsidiary of eCom eCom.com, Inc.

eCom eCom.com, Inc. spun off USAS Digital, Inc. on June 4, 2004. USAS Digital,
Inc. changed its name to CRT Holdings, Inc. on November 30, 2005. On October 1,
2007 CRT Holdings, Inc. changed its name to SEI Holdings, Inc.

The Company's main office is located at 1016 Clemons Street, Suite 302, Jupiter,
Florida 33477, and the telephone number is (561) 745-6789.

The Company does not have any off-balance sheet arrangements.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION, USE OF ESTIMATES
The Company maintains its accounts on the accrual basis of accounting. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

REVENUE RECOGNITION
Product revenue is recognized when the product is shipped. Service revenue is
recognized when the service is complete. Dividends from investments are
recognized when declared payable by the underlying investment. Capital gains
and losses are recorded on the date of the sale of the investment.

CASH
Cash consists of deposits in banks and other financial institutions having
original maturities of less than ninety days.

ALLOWANCE FOR DOUBTFUL ACCOUNTS
It is the policy of management to review the outstanding accounts receivable at
each year end, as well as the bad debt write-offs experienced in the past, in
order to establish an allowance for doubtful accounts for uncollectible
amounts.

NOTES TO FINANCIAL STATEMENTS

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

DEPRECIATION
Property and equipment is recorded at cost and depreciated over the estimated
useful lives of the related assets. Depreciation will be computed using the
straight-line method.

AMORTIZATION
The accounting for a recognized intangible asset acquired after June 30, 2001
is based on its useful life to the Company. If an intangible asset has a finite
life, but the precise length of that life is not known, that intangible asset
shall be amortized over management's best estimate of its useful life. An
intangible asset with a indefinite useful life is not amortized. The useful life
to an entity is the period over which the asset is expected to contribute
directly or indirectly to the future cash flows of that entity.

RECLASSIFICATION
Certain reclassifications have been made to the prior years financial
statements in order for them to be in conformity with the current years
presentation.

NOTE C - LOANS RECEIVABLE RELATED COMPANY

The loan receivable from a related party, is non-interest bearing,
non-collateralized and due on demand.

NOTE D - PROPERTY AND EQUIPMENT

Equipment is recorded at cost and is being depreciated over its estimated
useful life of seven years. Accumulated depreciation through August 31, 2007 and
2006 is $431 and $575.

Depreciation expense for the three month periods ended August 31, 2006 and 2005
is $59 and $59, respectively, and is included in the cost of sales.

NOTE E - PREPAID EXPENSES

The Company has prepaid expenses at August 31, 2007 and May 31, 2007 in the
amounts of $8 and $8 which consist of domain name registration fess.

NOTE F - CHANGE OF COMMON SHARES AUTHORIZED

The company changed the number of common shares authorized from 100 million to
300 million with the State of Florida on November 30, 2005. The par value of the
common stock remains at $0.01 per share. The financial statements presented have
been restated to reflect this change.

NOTE G - SHAREHOLDER LOANS PAYABLE

The Loans Payable in the amounts of $1,127 and $1,127 at August 31, 2007 and
May 31, 2007, respectively, are non-interest bearing, non-collateralized and due
on demand.

The Shareholder Loans Payable at August 31, 2007 in the amount of $49 were non-
interest bearing, non-collateralized and due on demand.

NOTE H - DEVELOPMENT STAGE ENTERPRISE

The Company has been and is currently in the development stage. It is the
intention of management to merge or acquire a company engaged in an energy type
of business.

NOTE I - INCOME TAXES

No provision for federal and state income taxes has been recorded because the
Company has incurred net operating losses since inception. The Company's net
operating loss carryforward as of August 31, 2007 totals approximately $300,000.
These carry forwards, which will be available to offset future taxable income,
expire beginning in 2024.

The Company accounts for income taxes in accordance with FASB Statement No.
109, Accounting for Income Taxes (FASB 109). Under FASB 109, income taxes are
provided for the tax effects of transactions reported in the financial
statements and consist of taxes currently due plus deferred taxes related to
certain income and expenses recognized in different periods for financial and
income tax reporting purposes. Deferred tax assets and liabilities represent
the future tax return consequences of those differences, which will either be
taxable or deductible when the assets and liabilities are recovered or settled.
Deferred taxes also are recognized for operating losses and tax credits that are
available to offset future taxable income and income taxes, respectively.  A
Valuation allowance is provided if it is more likely than not that some or all
of the deferred tax asset will not be realized.  See Note K.

NOTE J - STOCKHOLDERS' EQUITY

The computation of diluted loss per share for the three months ended August 31,
2007 does not include shares from potentially dilutive securities as the
assumption of conversion or exercise of these would have an anti-dilutive effect
on loss per share. In accordance with generally accepted accounting principles,
diluted loss per share is calculated using the same number of potential common
shares as used in the computation of loss per share before extraordinary items.

NOTE K - DEFERRED TAX ASSET

Deferred income taxes are provided for temporary differences between the
financial reporting and income tax basis of the Company's assets and
liabilities. Temporary differences, net operating loss carry forwards and
valuation allowances comprising the net deferred taxes on the balance sheets are
as follows:                                            AUGUST 31, 2006

                                                       ================
The Company does not believe that the realization of the related net deferred
tax asset meets the criteria required by generally accepted accounting
principles and, accordingly, the deferred income tax asset arising from such
loss carry forward has been fully reserved.

NOTE L - RELATED PARTY TRANSACTIONS

The Company has loans payable due to related company entities. eCom eCom.com,
Inc. is owed $228 for funds advanced to the Company for its operations. Diamond
Energy Partners, Inc. (f/k/a AAB National Company) is owed $300. Click to
Raffle.com is owed $800.

The Company is allocated certain expenses such as rent, travel and office &
administrative that are paid on behalf of the Company by American Capital
Holdings, Inc., a company that is related to the Company by mutual stockholders
and Directors. The total of expenses allocated to the Company in the three
months ended August 31, 2007 is $15,785. A portion or all of the liabilities
payable to American Capital are converted to common stock and paid in capital at
the end of each reporting period.

NOTE M - RECENT ACCOUNTING PRONOUNCEMENTS

The FASB issued SFAS No. 150, Accounting for Certain Financial Instruments with
Characteristics of both Liabilities and Equity, and is effective for financial
instruments entered into after May 31, 2003.  This Statement establishes
standards for how an issuer classifies and measures in its statement of
financial position certain financial instruments with characteristics of both
liabilities and equity.  It requires that an issuer classify a financial
instrument that is within its scope as a liability because that financial
instrument embodies an obligation of the issuer.

Statement of Financial Accounting Standards No. 151, Inventory Costs, is an
amendment of ARB No. 43, Chapter 4 and is effective for inventory costs incurred
during fiscal years beginning after June 15, 2005.  This statement amends ARB
43, Chapter 4, to clarify that abnormal amounts of idle facility expense,

freight, handling costs, and wasted materials (spoilage) should be recognized as
current-period charges.  In addition, this Statement requires that allocation of
fixed production overheads to the costs of conversion be based on the normal
capacity of the production facilities.

Statement of Financial Accounting Standards No. 152, Accounting for Real Estate
Time-Sharing Transactions, is an amendment of FASB Statements No. 66 and 67.

Statement of Financial Accounting Standards No. 153, Exchanges of Nonmonetary
Assets, was issued in December 2004.  The guidance in APB No. 29, Accounting for
Nonmonetary Transactions, is based on the principle that exchanges of
nonmonetary assets should be measured based on the fair value of the assets
exchanged.  The guidance in that Opinion, however, included certain exceptions
to that principle.  This Statement amends Opinion 29 to eliminate the exception
for nonmonetary exchanges of similar productive assets and replaces it with a
general exception for exchanges of nonmonetary assets that do not have
commercial substance.  A nonmonetary exchange has commercial substance if the
future cash flows of the entity are expected to change significantly as a result
of the exchange.

Statement of Financial Accounting Standards No. 154, Accounting Changes and
Error Corrections, was issued in May 2005.  This Statement requires
retrospective application to prior periods' financial statements of changes in
accounting principle, unless it is impracticable to determine either the
period-specific effects or the cumulative effect of the change.  When it is
impracticable to determine the period-specific effects of an accounting change
on one or more individual prior periods presented, this Statement requires that
the new accounting principle be applied to the balances of assets and
liabilities as of the beginning of the earliest period for which retrospective
application is practicable and that a corresponding adjustment be made to the
opening balance of retained earnings (or other appropriate components of equity
or net assets in the statement of financial position) for that period rather
than being reported in an income statement.  When it is impracticable to
determine the cumulative effect of applying a change in accounting principle to
all prior periods, this Statement requires that the new accounting principle be
applied as if it were adopted prospectively from the earliest date practicable.
This Statement requires that retrospective application of a change in accounting
principle be limited to the direct effects of the change.  Indirect effects of a
change in accounting principle, such as a change in nondiscretionary
profit-sharing payments resulting from an accounting change, should be
recognized in the period of the accounting change.  This Statement also requires
that a change in depreciation, amortization, or depletion method for long-lived,
nonfinancial assets be accounted for as a change in accounting estimate by a
change in accounting principle.  This Statement carries forward without change
the guidance contained in Opinion 20 for reporting the correction of an error in
previously issued financial statements and a change in accounting estimate.
This Statement also carries forward the guidance in Opinion 20 requiring
justification of a change in accounting principle on the basis of preferability.

Statement of Financial Accounting Standards No. 155, Accounting for Certain
Hybrid Financial Instruments, was issued in February 2006.  This Statement
permits fair value remeasurement for any hybrid financial instrument that
contains an embedded derivative that otherwise would require bifurcation;
clarifies which interest-only strips and principle-only strips are not subject
to the requirements of Statement 133; establishes a requirement to evaluate
interests in securitized financial assets to identify interests that are
freestanding derivatives or that are hybrid financial instruments that contain
an embedded derivative requiring bifurcation; clarifies that concentrations of
credit risk in the form of subordination are not embedded derivatives, and
amends Statement 140 to eliminate the prohibition on a qualifying special-
purpose entity from holding a derivative financial instrument that pertains to a
beneficial interest other than another derivative financial instrument.

Statement of Financial Accounting Standards No. 156, Accounting for Servicing of
Financial Assets, was issued in March 2006.  This Statement requires an entity
to recognize a servicing asset, a contract to service financial assets under
which the estimated future revenues from contractually specified servicing fees,
late charges, and other ancillary revenues are expected to more than adequately
compensate the servicer for performing the servicing, or servicing liability, a
contract to service financial assets under which the estimated future revenues
from contractually specified servicing fees, late charges, and other ancillary
revenues are not expected to adequately compensate the servicer for performing
the servicing, each time it undertakes an obligation to service a financial
asset by entering into a servicing contract.

SFAS No's. 150, 151, 152, 153, 154, 155 and 156 were adopted by the company and
did not have a material effect on the Company's financial position or results of
operations.

NOTE N - NAME CHANGE

October 1, 2007 CRT Holding, Inc. changed its name to SEI Holdings, INC. to

Certain statements in this report and elsewhere (such as in other filings by the
Company with the Securities and Exchange Commission ("SEC"), press releases,
presentations by the Company of its management and oral statements) may
constitute "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995.  Words such as "expects,"
"anticipates," "intends," "plans," "believes," "seeks," "estimates," and
"should," and variations of these words and similar expressions, are intended to
identify these forward-looking statements.  The company's actual results
could differ materially from those anticipated in these forward-looking
statements.  Factors that might cause or contribute to such differences include,
among others, failure to complete a merger or acquisition with a privately owned
operating business that is generating substantial revenues, success of the
Company's business operations, failure to obtain sufficient capital to fund
those operations, and failure to meet the qualifications for listing of the
Company's stock on a major stock exchange.  The Company undertakes no obligation
to publicly release the result of any revisions to these forward-looking
statements, which may be made to reflect events or circumstances after the date
hereof or to reflect the occurrence of unanticipated events.

ITEM 2.  MANAGEMENT'S DISCUSSION AND COMPARISON OF RESULTS OF OPERATIONS
         (CONTINUED)

History of Spin-Off Company:

On December 1, 2003, the Board of Directors of eCom approved the spin-off of
the Company.

On June 4, 2004, the Board of Directors of eCom readopted a resolution to
spinoff the Company and authorized whatever action necessary to complete this
process including acquisitions and mergers. In this regard, the board included
instructions for the distribution of stock by its Transfer Agent, Florida
Atlantic Stock Transfer (FAST), to the shareholders when the share certificates
were properly exercised and costs relating to the issuance of these shares were
paid in full. Notwithstanding the foregoing, eCom eCom was not able to pay FAST
the amounts required to send out the stock certificates to the shareholders,
and therefore,  the shares were not issued. Due to eCom's financial condition,
eCom was unable to effectuate the spinoffs. In connection with the spinoffs,
eCom owned all outstanding and issued shares of common stock of the Company. By
spinning off the Company, eCom distributed the common stock of the Company to
eCom's shareholders in proportion to the shares held in eCom as the relevant
record date.

On November 29, 2004, an involuntary petition was filed against eCom eCom.com,
Inc. under Chapter 11 Title 11, of the United States Bankruptcy Code.
Thereafter, an order for relief was entered by the United States Bankruptcy
Court on May 16, 2005. On June 2, 2005, the shares of the Spin-Off Company were
distributed to eCom shareholders of record, as of May 27, 2005. Subsequent
thereto, eCom caused a registration statement on Form 10-SB to be filed for the
Company.

On July 18, 2005, the Company received a letter from the Securities and
Exchange Commission asking it to provide legal analysis for the "spin-off"
share issuance. A copy of this letter is enclosed herein as Exhibit No. 99.1.

In an effort to give the SEC an answer regarding their request for detailed
clarification as to the legal analysis of the spin-off companies and to comply
with the request to withdraw each of the above referenced spin-off companies'
Form 10SBG12, on August 15, 2005 each spin-off company withdrew their
respective July 8, 2005 Form 10SBG12 filings.  On August 15, 2005 Barney A.
Richmond filed a reply with the SEC regarding their July 18, 2005
correspondence.  A copy of Mr. Richmond's legal analysis is enclosed as Exhibit

ITEM 2.  MANAGEMENT'S DISCUSSION AND COMPARISON OF RESULTS OF OPERATIONS
         (CONTINUED)

The Company has had no recent revenues or earnings from operations. The Company
will sustain operating expenses without corresponding revenues. This will
result in the Company incurring net operating losses until the Company can
realize profits from the business ventures it intends to acquire.

It is the intention of the Company to perform a merger or acquisition with a
privately owned operating business that is generating substantial revenues.
After a merger or acquisition has occurred, the Company will then file its Form
10-SB and SB-2.

Upon effectiveness of the Registration Statement, the Company intends to apply
to have its common stock listed for trading on the American Stock Exchange.
There is currently no public market for the Company's common stock, until such
time as the Company's Registration Statement under the Securities Act of 1933
and the Securities and Exchange Commission has been declared effective.

On June 22, 2007, the United States Securities & Exchange Commission ("SEC"),
via SEC File No. S7-11-07 and through Release No. 33-8813, issued proposed
revisions to Rule 144 and Rule 145 to Shorten Holding Period for Affiliates and
Non-Affiliates from Two (2) Years To Six (6) Months To Facilitate Capital
Raising For Smaller Companies. Comments from the public were due by September 4,
2007.

By waiting on clarification as to the outcome of the new SEC proposed 144 Rule,
if adopted, would reduce eighteen (18) months off the time that the 144
restriction may be removed; and would save significant SEC registration fee
costs for each company.  If this proposed rule is adopted by the SEC, 144
Private Placement shares will be automatically eligible for resale in six (6)
months.

As a result, the company is seeking to raise Three Hundred Thousand ($300,000)
U.S. Dollars through the issuance of a ten percent (10%) promissory note to be
used to fund general corporate operations, including pursuing merger and
acquisition opportunities.  For each $25,000 purchased, the promissory note
holder will receive ten percent (10%) interest, payable monthly plus one
hundred thousand (100,000) $.01 cent warrants in the company.

Repayment of the promissory note will come from the following intended sources:
1.   If the SEC 144 Six (6) Month Rule is adopted, the Company plans to
immediately prepare a SEC 506 Regulation D Private Placement 144 Equity
Offering.  The proceeds of this proposed 506 Regulation D Private Placement
will be used to repay this credit facility.

2.  If the SEC 144 Six (6) Month Rule is not adopted, the Company plans to
prepare a SEC 506 Regulation D Private Placement 144 Equity Offerings in
accordance with the existing two (2) year SEC 144 Rule.  Upon completion of
these offerings, several of the above described Companies would file SB-2 or

ITEM 2.  MANAGEMENT'S DISCUSSION AND COMPARISON OF RESULTS OF OPERATIONS
         (CONTINUED)

S-3 Registration Statements to register common shares for resale. The proceeds
of this proposed 506 Regulation D Private Placement will be used to repay this
credit facility.

The success of the Company's proposed plan of operation will depend primarily
on the success of the Company's business operations and the realization of the
business' perceived potential. The funding of this proposed plan will require
significant capital. There can be no assurance that the Company will be
successful or profitable if the Company is unable to raise the funds to provide
this capital, or to otherwise locate the required capital for the operations of
the business.

If, for any reason, the Company does not meet the qualifications for listing on
a major stock exchange, the Company's securities may be traded in the over-the-
counter ("OTC") market. The OTC market differs from national and regional stock
exchanges in that it (1) is not sited in a single location but operates through
communication of bids, offers and confirmations between broker-dealers and (2)
securities admitted to quotation are offered by one or more broker-dealers
rather than the "specialist" common to stock exchanges.

RESULTS OF OPERATIONS
---------------------
Comparison of the three months ended August 31, 2007
with the three months ended August 31, 2006
-------------------------------------------------------------------
Revenue for the three month periods ended August 31, 2007 and August 31, 2006
was $0.

Cost of sales, which includes depreciation expense, was $59 for both three month
periods.

Operating expenses for the three months ended August 31, 2007 totaled $(36,450)
compared to $(47,225) for the three months ended August 31, 2006.  These charges
consisted of general and administrative expenses which declined from the prior
year period because costs associated with bringing the Company current with
certain administrative requirements, including SEC filings, were greater during
the prior year time period.

As a result of the incurrence of the administrative expenses and depreciation
expense without the realization of revenues, the net loss for the three
months ended August 31, 2007 was $(38,840) versus a net loss of $(47,680)
recorded in the three months ended August 31, 2006.

Liquidity and Capital Resources
---------------------------------------
Currently there is no trading market for the Company's common stock, and there
can be no assurance that any trading market will ever develop or, if such a
market does develop, that it will continue.  As noted above, upon effectiveness

of a Registration Statement, the Company intends to apply to have its common
stock listed for trading on the American Stock Exchange. If, for any reason, the
Company does not meet the qualifications for listing on a major stock exchange,
the Company's securities may be traded in the over-the-counter ("OTC") market.

The Company continues to be reliant on the private sale of its restricted common
stock plus loans from stockholders and other related parties in order to fund
its operations.


ITEM 3. CONTROLS AND PROCEDURES

EVALUATION OF THE COMPANY'S DISCLOSURE CONTROLS AND INTERNAL CONTROLS:

Within the 90 days prior to the date of this Quarterly Report on Form 10-QSB,
the Company evaluated the effectiveness of the design and operation of its
'disclosure controls and procedures' ("Disclosure Controls"). This
'evaluation' ("Controls Evaluation") was done under the supervision and with the
participation of management, including the Chief Executive Officer/Chairman
("CEO") and Chief Financial Officer ("CFO"). As a result of this review, the
Company adopted guidelines concerning disclosure controls and the establishment
of a disclosure control committee made up of senior management.

LIMITATIONS ON THE EFFECTIVENESS OF CONTROLS:

The Company's management, including the CEO/CHAIRMAN and CFO, does not expect
that its Disclosure Controls or its 'internal controls and procedures for
financial reporting' ("Internal Controls") will prevent all error and all fraud.
Control system, no matter how well conceived and managed, can provide only
reasonable assurance that the objectives of the control system are met. The
design of a control system must reflect the fact that there are resource
constraints, and the benefits of controls must be considered relative to their
costs. Because of the inherent limitations in all control systems, no evaluation
of controls can provide absolute assurance that all control issues
and instances of fraud, if any, within the Company have been detected. These
inherent limitations include the realities that judgments in decision-making can
be faulty, and that breakdowns can occur because of simple error or mistake.

Additionally, controls can be circumvented by the individual acts of some
persons, by collusion of two or more people, or by management override of the
control. The design of any system of controls also is based in part upon certain
assumptions about the likelihood of future events, and there can be no assurance
that any design will succeed in achieving its stated goals under all potential
future conditions; over time, control may become inadequate because of changes
in conditions, or the degree of compliance with the policies or procedures may
deteriorate. Because of the inherent limitations in a cost-effective control
system, misstatements due to error or fraud may occur and not be detected.

CONCLUSIONS:

Based upon the Controls Evaluation, the CEO/Chairman and CFO have concluded
that, subject to the limitations noted above, the Disclosure Controls are
effective to timely alert management to material information relating to the
Company during the period when its periodic reports are being prepared.

In accordance with SEC requirements, the CEO/Chairman and CFO note that, since
the date of the Controls Evaluation to the date of this Quarterly Report, there
have been no significant changes in Internal Controls or in other factors that
could significantly affect Internal Controls, including any corrective actions
with regard to significant deficiencies and material weaknesses.
