MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

     The total return for Sequoia Fund was 8.34% for 2006, including the
reinvestment of dividends. This compares with the 15.80% return of the S&P 500.
As it has been for many years, our investment philosophy is to make concentrated
commitments of capital in a limited number of companies that have superior
long-term economic prospects and that sell at what we believe are attractive
prices. Because Sequoia is deliberately not representative of the overall
market, in any given year or years the performance of the Fund will often vary
significantly from that of the broad market indices.

     We are less concerned with the annual returns from each of the stocks we
own than with their returns over time. We have a similar attitude towards
earnings: we pay much more heed to earnings growth over a number of years rather
than over a single year, much less a quarter.

     The table below shows the twelve month stock total return for the Fund's
major positions at the beginning of 2006:

                           % OF ASSETS    TOTAL   % OF ASSETS
POSITION                     12/31/05    RETURN     12/31/06

Berkshire Hathaway            33.8%       24.1%      27.0%
Progressive Corp.             17.4%      -16.9%      14.3%
Mohawk Industries              8.0%      -13.9%       6.8%

                              ====                   ====

     The largest reasons for our underperformance versus the S&P 500 were the
significant stock price declines at two of our largest holdings, Progressive
Corp. and Mohawk Industries.

     We believed that Progressive's stock price at the beginning of 2006 was
justified by its historical record and long-term prospects together with its
exceptional management. Although we worried that Progressive's profit margins
were unsustainably high, we were confident the company would gradually reduce
prices and grow policies and revenue at satisfactory levels. We did not expect
that over the course of 2006 Progressive's revenue growth would decelerate to
zero and policies-in-force would begin to decline. Nor did we expect margins to
expand and earnings per share to grow 20%. Yet, that is what happened, although
we do not believe it was management's goal to harvest extra earnings in 2006 at
the expense of the future growth rate.

     For most of its history, Progressive's aim has been to earn at least a 4%
operating margin and grow as fast as possible. In 2006, it earned a 14% margin.
This windfall occurred largely because of a number of structural changes that
cumulatively have significantly reduced the frequency of automobile accidents.

     When Progressive tested lower rates in recent years, it found little
elasticity of demand. Therefore, at the risk of holding a pricing umbrella over
less efficient competitors, the company opted to preserve higher margins.
Although it anticipated that such pricing would reduce growth, it did not
contemplate that the growth would cease altogether.

     Looking ahead, Progressive may be forced to cut rates more aggressively to
attract policyholders, as more surgical price cuts have not worked. This almost
certainly will lead to lower profits for shareholders.

     Progressive is an outstanding company that currently faces two great
challenges: 1) increasing retention or policy lives through a number of
measures; and 2) improving both its brand proposition and its marketing and
advertising. Fortunately, management embraces change and the company could not
have a better change agent than CEO Glenn Renwick.

     Mohawk Industries' stock price fell 14% in 2006. Reported earnings rose 17%
for the year, reflecting earnings accretion from the purchase of Unilin, a large
European-based laminate flooring manufacturer, in late 2005. Absent the
acquisition of Unilin, net income would have been flattish as lower interest
expense from debt pay-down would have offset a modest decline in operating
profits at Mohawk's business units. The decline in operating income reflected
high oil prices, which increased the cost of the raw materials used to make
flooring products, and a slump in both new home construction and home
remodeling, which reduced demand for residential flooring. In this difficult
environment, Mohawk successfully managed operating costs and the acquisition of
Unilin. It also dramatically reduced the debt taken on to make the acquisition.

     We do not know how long the housing slump will last, or how long raw
materials prices will remain high. We do know Mohawk has been passing on raw

<Page>

materials price increases for some time, which speaks to its position in the
marketplace. At the end of 2006, Mohawk sold for less than 12 times forward
earnings estimates, which strikes us as an attractive price for a business that
has grown its earnings at a 17% compound average annual rate the last five
years.

     Berkshire Hathaway enjoyed a terrific year, though it received more than a
little help from Mother Nature. After two years which saw multiple hurricanes
wreak havoc on the Gulf Coast, writers of "supercat" reinsurance raised premiums
significantly, then saw no major storms hit the U.S. mainland in 2006. This
fortuitous circumstance helped Berkshire more than double its reported earnings
per share through the first nine months of the year. As a major writer of
"supercat" reinsurance, there will be years when Berkshire gets lucky, like
2006, and years when it pays out billions of dollars in claims, like 2004 and
2005. A prudent forecast for 2007 would include a more normalized level of
catastrophe claims, and thus a lower level of earnings in the reinsurance
business.

     Berkshire's good performance was not simply a matter of good weather. GEICO
is knocking the cover off the ball. The company's fantastic advertising,
together with its very aggressive entry into New Jersey, are driving very
satisfactory growth. Gen Re posted its best results in many years in 2006.
NetJets showed improved results. Most pleasingly, through the first three
quarters of the year Berkshire invested $14 billion in stock investments and
acquisitions of private companies. The favorable economics of these investments
gives us confidence that they will produce a very satisfactory return.

     Based on Berkshire's 2006 performance, our decision to reduce our ownership
position during the year could be second-guessed. It remains our single largest
investment but, given Mr. Buffett's age and our level of concentration, we felt
it prudent to reduce our exposure. We expect Mr. Buffett will continue to do a
masterful job deploying Berkshire's vast capital and we intend to benefit from
that performance over many years.

     TJX reported a fine year that highlighted the inherent strength of its
off-price business model. The company saw its earnings per share, absent
one-time charges, grow by more than 20%. In recent years, TJX had committed a
succession of gaffes, including the failed launch of a dot com business and the
rapid expansion of several unproven start-up concepts. Finally, in late 2005 the
board of directors tapped chairman of the board and founder Ben Cammarata to
return as interim CEO. Cammarata achieved almost immediate results by
re-focusing TJX on its core businesses, TJ Maxx, Marshall's and Winners, the TJ
Maxx of Canada. He replaced a number of senior managers and closed stores that
had little potential for earning a satisfactory return. Perhaps most importantly
he lured long-time executive Carol Meyrowitz, who had left the business earlier
in 2005, back to the company.

     Meyrowitz, a respected apparel merchant, was instrumental in the turnaround
and recently was appointed CEO. She should have a stronger supporting cast of
senior managers than existed 18 months ago. We trimmed TJX in 2006 after the
stock rose during the year, but it remains a large position and we are
encouraged by the changes made over the past five quarters.

     Other major holdings such as Brown & Brown, Expeditors, Fastenal, Idexx
Labs, O'Reilly, Porsche and Walgreen turned in strong earnings years, with all
of them growing net income at double-digit rates. Porsche shares rose 80% in
U.S. dollars. The stock price performance of the other six companies was more
mixed, but their earnings performance was on target. We are optimistic about the
prospects for solid earnings growth at all seven businesses in 2007 and beyond.

     We are pleased to report that we made a number of new investments in
high-quality businesses in 2006. Our largest new investment was Bed, Bath &
Beyond. This unusual company -- management rarely speaks to Wall Street, does
not belong to any industry trade groups and otherwise keeps its own counsel --
was founded in the early 1970s and today is a very successful purveyor of
kitchen, bath and home decor items. It is distinguished from its competitors by
its breadth of product offering and superior financial returns. The company has
a terrific balance sheet with an enormous amount of cash on hand and no debt.

     Other new investments by the Fund in 2006 included Target, Lowe's, Knight
Transportation, MasterCard and Apollo Group. During the year, the Fund sold its
holdings in Gtech and IGT.

     At the end of the year, Sequoia was 94.3% invested in stocks, compared to
95.2% a year earlier. In both years, the remainder of the Fund's assets was held
in cash and cash equivalents.

     The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

     Please note that the expenses shown in the table are meant to highlight
your ongoing costs only and will not help you determine the relative total costs
of owning different funds.

                               SEQUOIA FUND, INC.
                          NOTES TO FINANCIAL STATEMENTS

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

     Sequoia Fund, Inc. (the "Fund") is registered under the Investment Company
Act of 1940, as amended, as a non-diversified, open-end management investment
company. The investment objective of the Fund is growth of capital from
investments primarily in common stocks and securities convertible into or
exchangeable for common stock. The following is a summary of significant
accounting policies, consistently followed by the Fund in the preparation of its
financial statements.

A.   VALUATION OF INVESTMENTS: Investments are carried at market value or at
     fair value as determined by the Board of Directors. Securities traded on a
     national securities exchange or on a foreign exchange are valued at the
     last reported sales price on the principal exchange on which the security
     is listed on the last business day of the period; securities traded in the
     over-the-counter market are valued in accordance with NASDAQ Official
     Closing Price on the last business day of the period; listed securities and
     securities traded in the over-the-counter market for which no sale was
     reported on that date are valued at the mean between the last reported bid
     and asked prices; U.S. Treasury Bills with remaining maturities of 60 days
     or less are valued at their amortized cost. U.S. Treasury Bills that when
     purchased have a remaining maturity in excess of sixty days are stated at
     their discounted value based upon the mean between the bid and asked
     discount rates until the sixtieth day prior to maturity, at which point
     they are valued at amortized cost.

     FOREIGN CURRENCIES: Investment securities and other assets and liabilities
     denominated in foreign currencies are translated into U.S. dollar amounts
     at the date of valuation. Purchases and sales of foreign portfolio
     securities are translated into U.S. dollars at the rates of exchange
     prevailing when such securities are acquired or sold. Income and expenses
     are translated into U.S. dollars at the rates of exchange prevailing when
     accrued. The Fund does not isolate that portion of the results of
     operations resulting from changes in foreign exchange rates on investments
     from the fluctuations arising from changes in market prices of securities
     held. Such fluctuations are included with the net realized and unrealized
     gain or loss from investments. Reported net realized foreign exchange gains
     or losses arise from the sales of foreign currencies, currency gains or
     losses realized between the trade and settlement dates on securities
     transactions, and the difference between the amounts of dividends,
     interest, and foreign withholding taxes recorded on the Fund's books and
     the U.S. dollar equivalent of the amounts actually received or paid. Net
     unrealized foreign exchange gains and losses arise from changes in the fair
     values of assets and liabilities, other than investments in securities at
     fiscal period end, resulting from changes in exchange rates.

B.   ACCOUNTING FOR INVESTMENTS: Investment transactions are accounted for on
     the trade date and dividend income is recorded on the ex-dividend date.
     Interest income is accrued as earned. Premiums and discounts on fixed
     income securities are amortized over the life of the respective security.
     The net realized gain or loss on security transactions is determined for
     accounting and tax purposes on the specific identification basis.

C.   FEDERAL INCOME TAXES: It is the Fund's policy to comply with the
     requirements of the Internal Revenue Code applicable to regulated
     investment companies and to distribute all of its taxable income to its
     stockholders. Therefore, no federal income tax provision is required.

D.   USE OF ESTIMATES: The preparation of financial statements in conformity
     with accounting principles generally accepted in the United States 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 increases and decreases in net assets from operations during the
     reporting period. Actual results could differ from those estimates.

E.   GENERAL: Dividends and distributions to shareholders are recorded by the
     Fund on the ex-dividend date.

NOTE 2--INVESTMENT ADVISORY CONTRACTS AND PAYMENTS TO INTERESTED PERSONS:

     The Fund retains Ruane, Cunniff & Goldfarb Inc. as its investment adviser.
Ruane, Cunniff & Goldfarb Inc. (the "Investment Adviser") provides the Fund with
investment advice, administrative services and facilities.

     Under the terms of the Advisory Agreement, the Investment Adviser receives
a management fee equal to 1% per annum of the Fund's average daily net asset
values. This percentage will not increase or decrease in relation to increases
or decreases in the net asset value of the Fund. Under the Advisory Agreement,
the Investment Adviser is obligated to reimburse the Fund for the amount, if
any, by which the operating expenses of the Fund (including the investment
advisory fee) in any year exceed the sum of 1-1/2% of the average daily net
asset values of the Fund during such year up to a maximum of $30,000,000, plus
1% of the average daily net asset values in excess of $30,000,000. The expenses
incurred by the Fund exceeded the percentage limitation during the year ended
December 31, 2006 and the Investment Adviser reimbursed the Fund $1,102,000.
Such reimbursement is not subject to recoupment by the Investment Adviser.

     For the year ended December 31, 2006, there were no amounts accrued or paid
to interested persons, including officers and directors, other than advisory
fees of $35,499,566 to Ruane, Cunniff & Goldfarb Inc. and brokerage commissions
of $974,717 to Ruane, Cunniff & Goldfarb LLC., the Fund's distributor. Certain
officers of the Fund are also officers of the Investment Adviser and the Fund's
distributor. Ruane, Cunniff & Goldfarb LLC received no compensation from the
Fund on the sale of the Fund's capital shares during the year ended December 31,
2006.

NOTE 3--PORTFOLIO TRANSACTIONS:

     The aggregate cost of purchases and the proceeds from the sales of
securities, excluding U.S. government obligations, for the year ended December
31, 2006 were $460,370,370 and $775,697,004, respectively. Included in proceeds
of sales is $83,884,949 representing the value of securities distributed as
in-kind payment of redemptions, resulting in realized gains of $73,394,058.

     At December 31, 2006 the aggregate gross unrealized appreciation and
depreciation of securities for federal income tax purposes were $2,029,724,548
and $12,958,957, respectively.

NOTE 5--DISTRIBUTIONS TO SHAREHOLDERS:

     Distributions to shareholders are determined in accordance with federal tax
regulations and may differ from those determined for financial statement
purposes. To the extent these differences are permanent such amounts are
reclassified within the capital accounts based on federal tax regulations.
During the year ended December 31, 2006 permanent differences primarily due to a
net investment loss not deductible for tax purposes and realized gains on
redemptions in kind not recognized for tax purposes resulted in a net decrease
in net accumulated investment loss of $16,445,199 and undistributed net realized
gains of $75,594,555 with a corresponding increase in paid in surplus of
$59,149,356. These reclassifications had no effect on net assets.

     The tax character of distributions paid during 2006 and 2005 was as
follows:

                                                         2006           2005
                                                     ------------   ------------
Distributions paid from:
Ordinary income                                      $         --   $         --
Long-term capital gains                               340,945,549    245,091,727
                                                     ------------   ------------

                                                     ============   ============

     As of December 31, 2006, the components of distributable earnings on a tax
basis were as follows:

Undistributed long-term gain                                      $  126,058,241
Unrealized appreciation                                            2,016,765,591
                                                                  --------------
                                                                  $2,142,823,832
                                                                  ==============

NOTE 6--DIRECTORS FEES AND EXPENSES:

     Directors who are not deemed "interested persons" receive fees of $6,000
per quarter and $2,500 for each meeting attended, and are reimbursed for travel
and other out-of-pocket disbursements incurred in connection with attending
directors meetings. The total of such fees and expenses paid by the Fund to
these directors for the year ended December 31, 2006 was $242,010.

NOTE 7--NEW ACCOUNTING PRONOUNCEMENTS:

     In June 2006, the Financial Accounting Standards Board issued
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an
Interpretation of FASB Statement No. 109" (the "Interpretation"). The
Interpretation establishes a minimum threshold for financial statement
recognition of the benefit of positions taken in filing tax returns and requires
certain expanded tax disclosures. The Interpretation is effective for fiscal
years beginning after December 15, 2006, and is to be applied to all open tax
years as of the date of effectiveness. Management has not yet determined the
implication of the Interpretation to the Fund and its impact on the Fund's
financial statements.

     In addition, in September 2006, Statement of Financial Accounting Standards
No. 157, "Fair Value Measurements" (SFAS 157), was issued and is effective for
fiscal years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management has not yet determined the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
Sequoia Fund, Inc.

     In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Sequoia Fund, Inc. (the "Fund") at
December 31, 2006, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended and
the financial highlights for each of the five years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America. These financial statements and financial highlights (hereafter referred
to as "financial statements") are the responsibility of the Fund's management.
Our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements in
accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2006 by
correspondence with the custodian, provide a reasonable basis for our opinion.

ITEM 2.  CODE OF ETHICS.

As of the end of the period covered by this report, the registrant has adopted a
code of ethics, as defined in Item 2 of Form N-CSR, applicable to its principal
executive officer, principal financial officer, principal accounting officer or
controller, or persons performing similar functions. A copy of this code of
ethics is filed as an exhibit to this Form N-CSR, and also made available on the
Fund's website at: http://www.sequoiafund.com/code_of_ethics.htm. During the
period covered by this report, no substantive amendments were approved or
waivers were granted to the code of ethics.

ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant's Board of Directors has determined that the registrant does not
have an audit committee financial expert serving on its audit committee. The
registrant's Board of Directors has determined that, based on the background and
extensive experience of each of the members of the audit committee in the
financial services industry, a designated audit committee financial expert is
unnecessary. The members of the audit committee are well-known and respected
members of the investment management industry and the registrant is satisfied
that their collective knowledge and experience is sufficient for them to perform
their duties as audit committee members.

ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) - (d) Aggregate fees billed to the registrant for the last two fiscal year
for professional services rendered by the registrant's independent auditor were
as follows:

                             -----------------             -----------------
Audit Fees                        $49,000                       $45,000
Audit-Related Fees                   n/a                           n/a
Tax Fees                           $8,000                        $4,500
Other Fees                           n/a                            n/a

Audit fees include amounts related to the audit of the registrant's annual
financial statements and services normally provided by the auditor in connection
with statutory and regulatory filings. Tax fees include amounts related to tax
compliance and tax advice.


(e)(1) The registrant's audit committee has the responsibility to pre-approve
all audit and non-audit services provided to the registrant by its independent
auditor in advance at regularly scheduled audit committee meetings. The
registrant's audit committee also has the responsibility to pre-approve all
non-audit services provided by the registrant's independent auditor to the
registrant's investment adviser and any entity controlling, controlled by, or
under common control with the investment adviser that provides ongoing services
to the registrant, if the engagement relates directly to the operations and
financial reporting of the registrant, in advance at regularly scheduled audit
committee meetings.

(e)(2) No services included in (b)-(d) were approved pursuant to paragraph
(c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) The aggregate fees billed for the most recent fiscal year and the preceding
fiscal year by the registrant's independent auditor for non-audit services
rendered to the registrant, its investment adviser, and any entity controlling,
controlled by, or under common control with the investment adviser that provides
ongoing services to the registrant were $58,300 and $75,000, respectively.

(h) The registrant's audit committee has considered the provision of non-audit
services that were rendered to its investment adviser and any entity
controlling, controlled by, or under common control with the investment adviser
that provides ongoing services to the registrant and that were not pre-approved
and determined that those services are compatible with maintaining the
independent auditor's independence.

ITEM 5.  AUDIT COMMITTEE OF LISTED REGISTRANTS.

Not applicable.

ITEM 6.  SCHEDULE OF INVESTMENTS - INCLUDED IN ITEM 1, REPORTS TO STOCKHOLDERS

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END

officer have concluded that as of a date within 90 days of the filing of this
report there were no significant deficiencies in the design or operation of the
disclosure controls and procedures of the registrant which would have adversely
affected the ability of the registrant to record, process, summarize and report
the subject matter contained in this report.

(b) There were no significant changes in the registrant's internal controls
or in other factors that could significantly affect these controls subsequent to

of 2002 and required by Rule 30a-2(b) under the Investment Company Act, is
attached.
