                                     [ 11 ]


                  NOTES TO FINANCIAL STATEMENTS -- (unaudited)

      1. Significant  Accounting Policies -- Central Securities Corporation (the
"Corporation")  is  registered  under the  Investment  Company  Act of 1940,  as
amended, as a non-diversified,  closed-end  management  investment company.  The
following  is a summary  of the  significant  accounting  policies  consistently
followed by the Corporation in the preparation of its financial statements.  The
policies are in conformity with generally accepted accounting principles.

      Security Valuation -- Securities are valued at the last sale  or  official
        closing price or, if  unavailable,  at the closing bid price.  Corporate
        discount  notes and U.S.  Treasury  Bills are valued at amortized  cost,
        which  approximates  market value.  Securities for which no ready market
        exists,  including The Plymouth Rock Company, Inc. Class A Common Stock,
        are valued at estimated fair value by the Board of Directors.

      Federal  Income  Taxes  --  It  is  the  Corporation's  policy to meet 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 taxes have been accrued.

      Use  of  Estimates  --  The  preparation  of  the  financial statements in
        accordance  with  generally  accepted  accounting   principles  requires
        management  to make  estimates and  assumptions  that affect the amounts
        reported. Actual results could differ from those estimates.

      Other -- Security transactions are accounted for as of the trade date, and
        cost  of  securities  sold is  determined  by  specific  identification.
        Dividend income and  distributions  to stockholders  are recorded on the
        ex-dividend date. Interest income is accrued daily.

      New  Accounting  Pronouncements  --  In  September  2006,  the   Financial
        Accounting  Standards  Board issued  Statement 157 ("SFAS  157"),  "Fair
        Value  Measurements".  This Statement defines fair value,  establishes a
        framework  for  measuring  fair value in generally  accepted  accounting
        principles and expands disclosures about fair value  measurements.  SFAS
        157 will be effective at the beginning of the Corporation's  2008 fiscal
        year.  The  Corporation  is  currently  assessing  the  effect  of  this
        pronouncement on our financial statements.

        As of June  30,  2007,  the  Corporation  adopted  Financial  Accounting
        Standards Board Interpretation 48, "Accounting for Uncertainty in Income
        Taxes" ("FIN 48").  Management has determined that the implementation of
        FIN 48 had no impact in the financial statements.

      2. Common Stock -- The  Corporation  did not  repurchase any shares of its
Common Stock in the first six months of 2007.  It may from time to time purchase
Common Stock in such  amounts and at such prices as the Board of  Directors  may
deem advisable in the best interests of the stockholders. Purchases will only be
made at less than net asset value per share,  thereby  increasing  the net asset
value of shares held by the  remaining  stockholders.  Shares so acquired may be
held as treasury stock and available for optional stock distributions, or may be
retired.

      3. Investment  Transactions -- The aggregate cost of securities  purchased
and the aggregate  proceeds of securities  sold during the six months ended June
30, 2007,  excluding short-term  investments,  were $37,217,631 and $68,596,390,
respectively.

      As of June 30, 2007,  based on cost for Federal  income tax purposes,  the
aggregate gross unrealized appreciation and depreciation for all securities were
$396,764,568 and $4,382,532, respectively.

             NOTES TO FINANCIAL STATEMENTS -- continued (unaudited)

      4. Operating  Expenses -- The aggregate  remuneration  paid during the six
months ended June 30, 2007 to officers and  directors  amounted to $808,500,  of
which $71,000 was paid as fees to directors  who were not officers.  Benefits to
employees are provided through a profit sharing  retirement plan.  Contributions
to the plan are  made at the  discretion  of the  Board of  Directors,  and each
participant's  benefits vest after three years of employment.  No  contributions
were made to the plan for the six months ended June 30, 2007.

      5.  Affiliates  -- The Plymouth  Rock  Company,  Inc. and Neoware Inc. are
affiliates  as defined in the  Investment  Company  Act of 1940.  During the six
months ended June 30, 2007,  the  Corporation  received  dividends of $5,039,300
from affiliates and incurred a realized loss of $786,644 from the sale of shares
of an affiliate.  Unrealized  appreciation  related to  affiliates  increased by
$16,469,306 for the six months ended June 30, 2007 to $148,394,851.

      6. Restricted  Securities -- The Corporation  from time to time invests in
securities the resale of which is restricted.  On June 30, 2007 such investments
had an  aggregate  value  of  $149,406,285,  which  was  equal  to  22.0% of the
Corporation's net assets. Investments in restricted securities at June 30, 2007,
including acquisition dates and cost, were:



          Company                  Shares       Security        Date Acquired         Cost
-------------------------------    ------     ------------      -------------      ---------
                                                                       
Aerogroup International, Inc.      28,751     Common Stock         6/21/05          $ 17,200
The Plymouth Rock Company, Inc.    60,000     Class A Stock        12/15/82        1,500,000
The Plymouth Rock Company, Inc.    10,000     Class A Stock         6/9/84           699,986


      The  Corporation  does not have the  right to demand  registration  of the
restricted securities.  Unrealized appreciation related to restricted securities
increased by $15,112,490 for the six months ended June 30, 2007 to $147,189,453.

      7.  Operating  Lease  Commitment  -- The  Corporation  has entered into an
operating  lease for office space which  expires in 2014 and provides for future
minimum rental payments in the aggregate amount of  approximately  $2.5 million.
The lease agreement contains  escalation clauses relating to operating costs and
real property  taxes.  Future  minimum  rental  commitments  under the lease are
$314,241  per  year  through  2008,  $329,172  for 2009  and  $341,806  annually
thereafter.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

      TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF
        CENTRAL SECURITIES CORPORATION

            We  have   reviewed  the   accompanying   statement  of  assets  and
      liabilities, including the statement of investments, of Central Securities
      Corporation as of June 30, 2007, and the related statements of operations,
      changes  in net  assets,  cash  flows  and  financial  highlights  for the
      six-month period ended June 30, 2007.  These financial  statements are the
      responsibility of the management of Central Securities Corporation.

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

            We have previously audited, in accordance with standards established
      by the Public Company  Accounting  Oversight  Board (United  States),  the
      statement  of changes in net assets for the year ended  December  31, 2006
      and  financial  highlights  for each of the five years in the period ended
      December 31, 2006,  and in our report dated  January 24, 2007 we expressed
      an unqualified opinion on those financial statements.
