                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        

A.  BASIS OF PRESENTATION:

The Boston Beer Company, Inc. (the "Company") is engaged in the business of
brewing and selling beer, ale and cider products throughout the United States
and select international markets. The accompanying consolidated balance sheet as
of June 27, 1998 and the results of its consolidated operations and consolidated
cash flows for the three and six months ended June 27, 1998 and June 28, 1997
have been prepared by the Company, without audit, in accordance with generally
accepted accounting principles for interim financial information and pursuant to
the rules and regulations of the Securities and Exchange Commission.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements
and should be read in conjunction with the audited financial statements included
in the Company's Annual Report on Form 10-K for the year ended December 27,
1997. In the opinion of the management of the Company, the Company's unaudited
consolidated financial position as of June 27, 1998 and the results of its
consolidated operations and consolidated cash flows for the interim periods
ended June 27, 1998 and June 28, 1997, reflect all adjustments (consisting only
of normal and recurring adjustments) necessary to present fairly the results of
the interim periods presented. The operating results for the interim periods
presented are not necessarily indicative of the results expected for the full
year.


B.  SHORT TERM INVESTMENTS:

securities backed by various agencies of the U.S. Government have a cost of

D.  INCOME TAXES:

The Company's effective tax rate decreased to 39.6% for the three months ended
June 27, 1998 from 43.7% for the three months ended June 28, 1997 and increased
to 49.1% for the six months ended June 27, 1998 from 43.7% for the six months
ended June 28, 1997. The changes in the Company's effective tax rate for both
the three and six month periods were influenced primarily by the accounting for
the marketable equity security described in Note B, as the Company does not
expect that it will be able to fully realize the tax benefit associated with the
disposition of the security. The following table reconciles the Company's
federal statutory rate to the effective rate:

TEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

The following is a discussion of the financial condition and results of
operations of the Company for the three and six-month periods ended June 27,
1998 as compared to the three and six-month period ended June 28, 1997. It
should be read in conjunction with the "Consolidated Financial Statements" of
the Company and related "Notes to the Financial Statements" included in this
Form 10-Q.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 27, 1998 COMPARED TO THREE MONTHS ENDED JUNE 28, 1997

SALES.  Volume decreased by 16.3% to 324,000 barrels in the three months ended
June 27, 1998 from 387,000 barrels in the three months ended June 28, 1997. This
decrease is mainly due to discontinued and decreased contract brewing
arrangements with other companies the Company had in its Cincinnati brewery.
This reduced volume accounted for approximately 53,000 barrels. Net sales
decreased by 6.6% to $46,530,000 in the three-month period ended June 27, 1998
from $49,838,000 in the three-month period ended June 28, 1997. The decrease in
net sales was attributable in part by increased spending in discounts and
allowances and in part by the Company's reduced volume.

GROSS PROFIT.  Gross profit decreased by 3.4% to $24,299,000 in the three months
ended June 27, 1998 from $25,167,000 in the three months ended June 28, 1997.
Offsetting the volume decline was a reduction in cost of sales to 47.8% of net
sales in the three months ended June 27, 1998 from 49.5% in the three months
ended June 28, 1997. This decrease is due to a favorable trend in raw material
and packaging costs.

ADVERTISING, PROMOTIONAL AND SELLING.  Advertising, promotional and selling
expenses decreased by 7.2% to $18,393,000 in the three months ended June 27,
1998 from $19,829,000 in the three months ended June 28, 1997. This decrease was
primarily attributable to a reduction in employee-related expenses, a reduction
in POS-related expenses and a decrease in promotional spending. Partially
offsetting this decrease was an increase in advertising expense. As a percentage
of net sales, total advertising, promotional and selling expenses decreased to
39.5% in the three months ended June 27, 1998 from 39.8% in the three months
ended June 28, 1997.

GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased by
3.8% to $3,214,000 in the three months ended June 27, 1998 from $3,097,000 in
the three months ended June 28, 1997. This increase was primarily due to an
increase in  depreciation, which reflects an increase in leasehold improvements,
legal and bad debt expense.  Partially offsetting these increases were cost
savings in employee and insurance related charges. As a percentage of net sales,
general and administrative expenses increased to 6.9% for the three months ended
June 27, 1998 from 6.2% for the three months ended June 28, 1997.

OPERATING INCOME.  Operating income increased by 20.1% to $2,692,000 in the
three months ended June 27, 1998 from $2,241,000 in the three months ended June
28, 1997. This increase was due mainly to reduced spending in promotional and
selling expenses.

OTHER INCOME (EXPENSE), NET:  Other income (expense) net, was $1,166,000 for the
three months ended June 27, 1998, versus $304,000 for the three months ended
June 28, 1997. This increase is due to the adjustment in the original write down
of the marketable security of $2,317,000 which took place in the first quarter
of 1998.  Following the first quarter write down, the Company disposed of the
security in the second quarter and recorded a gain of $882,000.

NET INCOME.  Net income increased by 62.5% to $2,332,000 in the three months
ended June 27, 1998 from $1,435,000 in the three months ended June 28, 1997. The
increase is primarily due to reductions in cost of sales, lower spending in
promotional and selling expenses and the $882,000 adjustment to offset the write
down of the marketable security. Income tax expense decreased to 39.6% of pretax
income or $1,526,000 for the three months ended June 27, 1998 from 43.7% of
pretax income or $1,110,000 for the three months ended June 28, 1997. This
decrease in the tax rate is caused primarily by the adjustment to the write down
of the marketable security.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS (CONTINUED)

SIX MONTHS ENDED JUNE 27, 1998 COMPARED TO SIX MONTHS ENDED JUNE 28, 1997

SALES.  Sales volume decreased by 5.1% to 634,000 barrels in the first six
months of 1998 from 668,000 barrels in the first six months of 1997. This
decrease is due to discontinued and decreased contract brewing arrangements with
other companies which the Company had at its Cincinnati brewery. This reduced
volume accounted for approximately 47,000 barrels.  Sales of the Company's core
products have increased 2.3% in the first six months of 1998, due in part to the
Company's introduction of White Ale in January of 1998. Despite the loss of
volume, net sales increased to $91,779,000 in the first six months of 1998 from
$91,693,000 in the first six months of 1997, as sales of products produced by
the Cincinnati brewery to others are made at prices much lower than those of the
Company's core products.

GROSS PROFIT.  Gross profit increased by 6.7% to $48,121,000 in the first six
months of 1998 from $45,115,000 in the first six months of 1997. Cost of sales
decreased to 47.6% of net sales in the first six months of 1998 from 50.8% of
net sales in the first six months of 1997. This decrease is due to a favorable
trend in raw material and packaging costs.

ADVERTISING, PROMOTIONAL AND SELLING.  Advertising, promotional, and selling
expenses decreased by 7.1% to $31,934,000 in the first six months of 1998 from
$34,387,000 in the first six months of 1997. This decrease was primarily
attributable to a reduction in employee-related expenses, a reduction in POS-
related expenses, and a decrease in promotional spending. Partially offsetting
this decrease was an increase in advertising expense. As a percentage of net
sales, total advertising, promotional, and selling expenses decreased to 34.8%
in the first six months of 1998 from 37.5% in the first six months of 1997.

GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased by
6.8% to $6,438,000 in the first six months of 1998 from $6,027,000 in the first
six months of 1997. This increase is due mainly to the inclusion of G & A
expenses of the Company's brewery in Cincinnati. The Company purchased the
brewery on March 1,1997; therefore, only four months of brewing operations are
reflected in the expense for the comparable 1997 period. Also adding to the
increase in G & A are increases in depreciation and legal fees. As a percentage
of net sales, general and administrative expenses increased to 7.0% in the first
six months of 1998 from 6.6% in the first six months of 1997.

OPERATING INCOME.  Operating income increased by 107% to $9,749,000 in the first
six months ended June 27,1998 from $4,701,000 in the first six months ended June
28, 1997. This increase was due to higher sales caused by the White Ale
introduction, savings in cost of sales and reduced spending in promotional and
selling expenses

OTHER INCOME (EXPENSE), NET:  Other income (expense) net, was ($1,094,000) in
the first six months of 1998 vs. $654,000 for the first six months of 1997. This
change is due to the loss on the sale of a marketable security of $1,435,000
offset somewhat by interest income.

NET INCOME.  Net income increased by 46.2% to $4,409,000 in the first six months
of 1998 compared to $3,015,000 in the first six months of 1997. The increase is
primarily due to increased sales volume, reductions in cost of sales, lower
spending in promotional and selling expenses offset by the loss on the sale of
the marketable security. Income tax expense increased to 49.1% of pretax income
or $4,246,000 for the six months ended June 27,1998 from 43.7% of pretax income
or $2,340,000 for the six months ended June 28, 1997. This increase in the tax
rate is caused by the loss on the sale of the marketable security which reduced
the profit before taxes for financial reporting but not for tax purposes, as the
Company does not expect that it will be able to fully realize the tax benefit
associated with the disposition of the security.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS  (CONTINUED)

LIQUIDITY AND CAPITAL RESOURCES

During the first six months of 1998, the Company recorded net income of
$4,409,000, while net cash generated by operating activities was $9,006,000.
This $4,597,000 difference is primarily due to the amortization of a long term
deferred contract incentive an increase in accrued expenses and depreciation and
the loss on the disposition of the marketable security, offset by an increase in
accounts receivable and reductions in accounts payable.

During the first six months of 1998, the Company used $4,909,000 in investing
activities. This reflects the purchase of $1,649,000 in government securities,
the purchase of $4,048,000 of fixed assets, consisting mainly of brewery and
packaging equipment at the Company's Cincinnati brewery and its contract
breweries, offset by the gain on the disposition of the marketable security of
$788,000.

During the first six months of 1998, the Company generated $149,000 from
financing activities, which primarily reflects proceeds from the sale of stock
under the employee purchase plan.

Assuming there is no significant change in the Company's business, the Company
believes that working capital of $58,589,000 as of June 27, 1998 (of which 71.2%
is in cash and equivalents and short term investments), in conjunction with
existing lines of credit, should be sufficient to meet the Company's operating,
capital and debt service requirements over the next few years.

YEAR 2000

Many computer systems experience problems handling dates beyond the year 1999.
Therefore, some computer hardware and software will need to be modified prior to
the year 2000 in order to remain functional. The Company is assessing both the
internal readiness of its systems as well the compliance of its vendors for the
handling of the year 2000. The Company expects to implement successfully the
systems and programming changes necessary to address year 2000 issues, and does
not believe that the cost of such actions will have a material effect on the
Company's results of operations or financial condition. There can be no
assurance, however, that there will not be a delay in, or increased costs
associated with, the implementation of such changes, and the Company's inability
to implement such changes could have an adverse effect on future results of
operations.

         Section 3.1  Annual Meeting
         ---------------------------

         The Annual Meeting of the Stockholders shall be held at 10 o'clock
A.M., Eastern Daylight Time, on the third Tuesday of April in each year, if not
a legal holiday, and, if a legal holiday, then on the next secular day
following, or at such other date and time within six months after the end of the
Corporation's fiscal year as shall be designated from time to time by the Board
of Directors, the Chairman of the Board of Directors or the President and stated
in the notice of the meeting.  Purposes for which an Annual Meeting is to be
held, additional to those prescribed by law and these By-Laws, may be specified
by the President or by the Directors.

         If such Annual Meeting has not been held as herein provided, a Special
Meeting of the Stockholders in lieu of the Annual Meeting may be held, and any
business transacted or elections held at such Special Meeting shall have the
same effect as if transacted or held at the Annual Meeting, and in such case all
references to these By-Laws, except in this Section 3.1, to the Annual Meeting
of the Stockholders shall be deemed to refer to such Special Meeting.  Any such
Special Meeting shall be called, and the purposes thereof shall be specified in
the Call, as provided in Section 3.2 of this Article 3.

         Section 3.2  Special Meetings
         -----------------------------

         A Special Meeting of the Stockholders may be called at any time by the
President, or by a majority of the Directors acting by vote or by written
instrument or instruments signed by them.  A Special Meeting of Stockholders
shall be called by the Clerk, or in the case of the death, absence, incapacity
or refusal of the Clerk, by any other officer, 

                                       5

<PAGE>
 
upon written application of one or more stockholders who hold at least one-tenth
part in interest of the stock entitled to vote at the meeting. Such Call shall
state the time, place, and purposes of the meeting.

         Section 3.3  Place of Meetings
         ------------------------------

         All meetings of the stockholders shall be held at the principal office
of the Corporation in Massachusetts, unless a different place within
Massachusetts or, if permitted by the Articles of Organization, elsewhere within
the United States is designated by the Chairman of the Board of Directors, the
President, or by a majority of the Directors acting by vote or by written
instrument or instruments signed by them.  Any adjourned session of any meeting
of the stockholders shall be held at such place within Massachusetts or, if
permitted by the Articles of Organization, elsewhere within the United States as
is designated in the vote of adjournment.

         Section 3.4  Notice of Meetings
         -------------------------------

         A written Notice of the place, date and hour of all meetings of
stockholders stating the purposes of the meeting shall be given at least seven
(7) calendar days before the meeting to each stockholder of the Corporation,
whether or not such stockholder is entitled to vote thereat, by leaving such
Notice with him or at his residence or usual place of business, or by mailing,
postage prepaid, and addressed to such stockholder at his address as it appears
in the records of the Corporation.  Such Notice shall be given by the Clerk, or
in the case of the death, absence, incapacity or refusal of the Clerk, by any
other officer or by a person designated either by the Clerk, the person or
persons calling the meeting or by the Board of Directors.  Whenever Notice of a
meeting is required to be given a stockholder under any provision of law, of the
Articles of Organization, or of these By-Laws, a written Waiver 

                                       6

<PAGE>
 
thereof, executed before or after the meeting by such stockholder or his
attorney thereunto authorized, and filed with the records of the meeting, shall
be deemed equivalent to such Notice.

         Section 3.5  Quorum
         -------------------

         At any meeting of the stockholders, a quorum for the election of any
Director or for the consideration of any question shall consist of a majority in
interest of all stock issued, outstanding and entitled to vote at such election
or upon such question, respectively, except that if two or more classes of stock
are entitled to vote as separate classes for the election of any Director or
upon any question, then in the case of each such class a quorum for the election
of any Director or for the consideration of such question shall consist of a
majority in interest of all stock of that class issued, outstanding and entitled
to vote thereon.  Stock owned by the Corporation, if any, except stock held
directly or indirectly by it in a fiduciary capacity, shall be disregarded in
determining any quorum.  Whether or not a quorum is present, any meeting may be
adjourned from time to time by a majority of the votes properly cast upon the
question, and the meeting may be held as adjourned without further notice.

         When a quorum for an election is present at any meeting, a plurality of
the votes properly cast for any office shall elect such office.  When a quorum
for the consideration of a question is present at any meeting, a majority of the
votes properly cast upon the question shall decide the question; except that if
two or more classes of stock are entitled to vote as separate classes upon such
question, then in the case of each such class a majority of the votes of such
class properly cast upon the question shall decide the vote of that class upon
the question; and except in any case where a larger vote is required by law or
by the Articles of Organization.

         Section 3.6  Action without Meeting
         -----------------------------------

         Any action required or permitted to be taken at any meeting of the
stockholders may be taken without a meeting if all stockholders entitled to vote
on the matter consent to the 

                                       7

<PAGE>
 
action in writing and the written Consents are filed with the records of the
meetings of stockholders. Such consents shall be treated for all purposes,
including without limitation for the purposes of Section 4.8 hereof as a vote at
a meeting.

         Section 3.7  Proxies and Voting
         -------------------------------

         Except as may otherwise be provided in the Articles of Organization,
stockholders entitled to vote shall have one vote for each share of stock
entitled to vote owned by them.  Stockholders entitled to vote may vote in
person or by proxy.  Except as otherwise provided by law, no proxy dated more
than six (6) months before the meeting named therein shall be valid and no proxy
shall be valid after the final adjournment of such meeting.  A proxy with
respect to stock held in the name of two or more persons shall be valid if
executed by any one of them unless at or prior to the exercise of the proxy the
Corporation receives specific written notice to the contrary from any one of
them.  A proxy purporting to be executed by or on behalf of a stockholder shall
be deemed valid unless challenged at or prior to its exercise and the burden of
proving invalidity shall rest on the challenger.  Proxies shall be filed with
the Clerk, or person performing the duties of the Clerk, at the meeting, or any
adjournment thereof, before being voted.

         The Corporation shall not, directly or indirectly, vote upon any share
of its own stock; but nothing herein shall be construed as limiting the right of
the Corporation to vote shares of stock held directly or indirectly by it in a
fiduciary capacity.

Common Stock (the "Class A Directors") and not fewer than five (5) nor more than
seven (7) Directors elected by the Corporation's Class B Common Stock (the

number of Class A Directors is then, or previously, elected. The Directors shall
be chosen at the Annual Meeting of the Stockholders by such stockholders as have
the right to vote thereon, in accordance with Section 4.8 of these By-Laws. Each
Director shall hold office until the next annual election of Directors and until

                    Indemnification of Directors and Others
                    ---------------------------------------

         Section 7.1  Definitions
         ------------------------

         For purposes of this Article 7:

          (a)  "Director - or - Officer" means any person who is serving or has
served as a Director, officer or employee of the Corporation appointed or
elected by the Board of Directors or the stockholders of the Corporation, or any
Director, officer or employee of the Corporation who is serving or has served at
the request of the Corporation as a Director, officer, trustee, principal,
partner, member of a committee, employee or other agent of any other
organization, or in any capacity with respect to any employee benefit plan of
the Corporation or any of its subsidiaries.

          (b)  "Proceeding" means any action, suit or proceeding, whether civil,
criminal, administrative or investigative, brought or threatened in or before
any court, tribunal, administrative or legislative body or agency, and any claim
which could be the subject of a Proceeding.

          (c)  "Expense" means any fine or penalty, and any liability fixed by a
judgment, order, decree or award in a Proceeding, any amount reasonably paid in
settlement of a Proceeding and any professional fees and other disbursements
reasonably incurred in connection with a Proceeding.  The term "Expense" shall
include any taxes or penalties imposed on a Director or Officer with respect to
any employee benefit plan of the Corporation or any of its subsidiaries.

         Section 7.2  Right to Indemnification
         -------------------------------------

         Except as limited by law or as provided in Sections 7.3 and 7.4 of this
Article 7, each Director or Officer (and his heirs and personal representatives)
shall be indemnified by the Corporation against any Expense incurred by him in
connection with each Proceeding in which he is involved as a result of his
serving or having served as a Director or Officer.

         Section 7.3  Indemnification not Available
         ------------------------------------------

         No indemnification shall be provided to a Director or Officer with
respect to a Proceeding as to which it shall have been adjudicated that he did
not act in good faith in the reasonable belief that his action was in the best
interests of the Corporation, or, to the extent that such Proceeding relates to
service with respect to an employee benefit plan, in the best interests of the
participants or beneficiaries of such employee benefit plan.

         Section 7.4  Compromise or Settlement
         -------------------------------------

         In the event that a Proceeding is disposed of by settlement or in the
event of any adjudication which, in the opinion of a majority of the
disinterested Directors (who may consult or defer to the opinion of the General
Counsel or outside counsel to be employed by the Corporation) or, if there are
no disinterested Directors, the General Counsel (who may consult or defer to the
opinion of outside counsel to be employed by the Corporation), does not make a
sufficient determination of conduct which could preclude or permit
indemnification in accordance with this section 7, the Director or Officer shall
be entitled to indemnification unless, as determined by a majority of the
disinterested Directors (who may consult or defer to the opinion of the General
Counsel or outside counsel to be employed by the Corporation) or, if there are
no disinterested directors, the General Counsel (who may consult or defer to the
opinion of outside counsel to be employed by the Corporation), such Director or
Officer's conduct was such as precludes indemnification under this Section 7.

         Section 7.5  Advances
         ---------------------

         The Corporation shall pay sums on account of indemnification in advance
of a final disposition of a Proceeding upon receipt of an undertaking by the
Director or Officer to repay such sums if it is subsequently established that he
is not entitled to indemnification pursuant to Sections 7.3 and 7.4 hereof,
which undertaking may be accepted without reference to the financial ability of
such person to make repayment.

indemnification existing independently of this Article 7.

         Section 7.7  Insurance
         ----------------------

         The provisions of this Article 7 shall not limit the power of the Board
of Directors to authorize the purchase and maintenance of insurance on behalf of
any Director or Officer against any liability incurred by him in any such
capacity, or arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability under this Article
7.

Articles of Organization and Amendments thereto may be issued, and any shares of
capital stock restored to the status of authorized but unissued stock may be
reissued, by vote of the Directors.  No stock shall be issued unless the cash,

be prescribed from time to time by the Directors or stockholders, stating the
number and the class and the designation of the series, if any, of the shares
held by him.  Such certificates shall be signed by the President or a Vice
President and by the Treasurer or an Assistant Treasurer.  Such signatures may
be facsimiles if the certificate is signed by a duly appointed transfer agent or
registrar, other than a Director, officer or employee of the Corporation.  In
case any officer who has signed or whose facsimile signature has been placed on
such certificate shall have ceased to be such officer before such certificate is
issued, it may be issued by the Corporation with the same effect as if he were
such officer at the time of its issue.

         Every certificate issued by the Corporation for shares of stock at a
time when such shares are subject to any restriction on transfer pursuant to the
Articles of Organization, the By-Laws, the Stockholder Rights Agreement dated
November __, 1995, entered into among the Corporation and all of the then
holders of Class A Common Stock and Class B Common Stock (the "Stockholder
Rights Agreement") or any other agreement to which the Corporation is a party
shall have the restriction noted conspicuously on the certificate and shall also
set forth on the face or back of the certificate either the full text of the
restriction, or a statement of the existence of such restriction and a statement
that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.  Every stock certificate
issued by the Corporation at a time when it is authorized to issue more than one
class or series of stock shall set forth upon the face or back of the
certificate either the full text of the preferences, voting powers,
qualifications and special and relative rights of the shares of each class and
series, if any, authorized to be issued, as set forth in the Articles of
Organization or, where applicable, any agreement, or a statement of the
existence of such preferences, powers, qualifications and rights and a statement
that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.

such conditions as the Directors may reasonably determine.

         Section 8.5  Transfers
         ----------------------

         Subject to the restrictions, if any, imposed by the Articles of
Organization, the By-Laws, the Stockholder Rights Agreement or any other
agreement to which the Corporation is a party, shares of stock shall be
transferred on the books of the Corporation only by the surrender to the
Corporation or its transfer agent of the certificate representing such shares
properly endorsed or accompanied by a written assignment of such shares or by a
written power of attorney to sell, assign or transfer such shares, properly
executed, with necessary transfer stamps affixed, and with such proof that the
endorsement, assignment or power of attorney is genuine and effective as the
Corporation or its transfer agent may reasonably require.  Except as may
otherwise be required by law, the Corporation shall be entitled to treat the
record holder of stock as shown on its books as the owner of such stock for all
purposes, including the payment of dividends and the right to vote with respect
thereto, regardless of any transfer, pledge or other disposition of such stock,
until the shares have been transferred on the books of the Corporation in
accordance with the requirements of these By-Laws.  It shall be the duty of each
stockholder to notify the Corporation of his post office address.

         Section 8.6  Record Date
         ------------------------

         The Directors may fix in advance a time, which shall be not more than
sixty (60) calendar days before the date of any meeting of stockholders or the
date for the payment of any dividend or the making of any distribution to
stockholders or the last day on which the consent or dissent of stockholders may
be effectively expressed for any purpose, as the record date for determining the
stockholders having the right to notice of and to vote at such meeting and any
adjournment thereof or the right to receive such dividend or distribution or the
right to give such consent or dissent, and in such case only stockholders of
record on such date shall

                                       21

have such right, notwithstanding any transfer of stock on the books of the
Corporation after the record date; or without fixing such record date the
Directors may for any such purposes close the transfer books for all or any part
