                                      [11]


                  NOTES TO FINANCIAL STATEMENTS -- (unaudited)

      1. Significant  Accounting Policies -- 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 U.S. generally
accepted accounting principles.

      Security  Valuation --  Securities  are valued at the last or closing sale
         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 U.S. 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  date  the
         securities  are  purchased  or  sold,  and cost of  securities  sold is
         determined   by   specific   identification.    Dividend   income   and
         distributions to stockholders are recorded on the ex-dividend date.

      2.  Common  Stock -- The  Corporation  repurchased  546,800  shares of its
Common  Stock in the first six months of 2006 at an average  price of $24.69 per
share,  representing an average discount from net asset value of 13.41%.  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,  available for
optional stock distributions, or maybe retired.

      3. Investment  Transactions -- The aggregate cost of securities  purchased
and the aggregate  proceeds of securities  sold during the six months ended June
30, 2006,  excluding short-term  investments,  were $44,532,787 and $50,042,805,
respectively.

      As of June 30, 2006,  based on cost for Federal  income tax purposes,  the
aggregate gross unrealized appreciation and depreciation for all securities were
$328,565,140 and $6,348,574, respectively.

      4. Operating  Expenses -- The aggregate  remuneration  paid during the six
months ended June 30, 2006 to officers and  directors  amounted to $551,750,  of
which $69,250 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. No contributions were made to the
plan for the six months ended June 30, 2006.

             NOTES TO FINANCIAL STATEMENTS -- continued (unaudited)

      5.  Affiliates  -- The  Plymouth  Rock  Company,  Inc. is an  affiliate as
defined in the Investment  Company Act of 1940. During the six months ended June
30, 2006, the Corporation  received  dividends of $4,185,300 from affiliates and
earned a realized  gain of  $4,059,424  from the sale of shares of an affiliate.
Unrealized  appreciation  related to affiliates  increased by $6,504,363 for the
six months ended June 30, 2006 to $116,800,014.

      6. Restricted  Securities -- The Corporation  from time to time invests in
securities the resale of which is restricted.  On June 30, 2006 such investments
had an  aggregate  value  of  $119,862,530,  which  was  equal  to  20.0% of the
Corporation's net assets. Investments in restricted securities at June 30, 2006,
including acquisition dates and cost, were:



       Company                       Shares            Security        Date Purchased        Cost

Aerogroup International, Inc.        28,751           Common Stock        6/21/05         $ 17,200
The Plymouth Rock                    70,000           Class A Common     12/15/82        1,500,000

      The  Corporation  does not have the  right to demand  registration  of the
restricted securities.  Unrealized appreciation related to restricted securities
increased by $10,717,645 for the six months ended June 30, 2006 to $117,645,344.

      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  $2.8 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 for 2006 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, 2006, and the related statements of operations,  changes in net assets,
cash flows and  financial  highlights  for the  six-month  period ended June 30,
2006.  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,  2005 and  financial
highlights for each of the five years in the period ended December 31, 2005, and
in our report  dated  January 27, 2006 we expressed  an  unqualified  opinion on
those financial statements.

                                                                        KPMG LLP

of managing their  investment.  Stockholders  wishing  certificates  may request
