PART I. ITEM 1.
FINANCIAL STATEMENTS (CONTINUED)
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - STATE STREET CORPORATION
(UNAUDITED)
 
 
NOTE A--BASIS OF PRESENTATION
 
  State Street Corporation ("State Street" or the "Corporation") is a
financial services corporation that provides banking, global custody,
investment management, administration and securities processing services to
both U.S. and non-U.S. customers. State Street reports three lines of
business. Services for Institutional Investors include accounting, custody,
daily pricing, administration, foreign exchange, cash management and
information services to support institutional investors and for large
portfolios of investment assets. Investment Management provides an extensive
array of services for managing financial assets worldwide for both
institutional and individual investors as well as record keeping and
investment services for defined contribution plans. Commercial Lending
activities include loans and other credit services for regional middle-market
companies, selected industries nationwide, broker/dealers, leasing and
international trade finance.
 
  The consolidated financial statements include the accounts of State Street
and its subsidiaries, including its principal subsidiary, State Street Bank
and Trust Company ("State Street Bank"). The preparation of financial
statements requires management to make estimates and assumptions that affect
the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates. All significant intercompany
balances and transactions have been eliminated upon consolidation. The results
of operations of businesses purchased are included from the date of
acquisition. Investments in affiliates owned less than 50% are accounted for
by the equity method. Certain previously reported amounts have been
reclassified to conform to the current method of presentation.
 
  For the Consolidated Statement of Cash Flows, State Street has defined cash
equivalents as those amounts included in the Consolidated Statement of
Condition caption, "Cash and due from banks".
 
  Effective January 1, 1998, State Street adopted SFAS No. 130, "Reporting
Comprehensive Income" which establishes standards for reporting comprehensive
income. Disclosures required by SFAS No. 130 are presented in the Statement of
Changes in Stockholders' Equity and Footnote E to the Consolidated Financial
Statements.
 
  In 1997, SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information" was issued. This statement establishes standards for
reporting information about operating segments in annual and interim financial
statements. This statement is effective for annual periods beginning after
December 15, 1997, and for interim periods beginning after December 15, 1998.
State Street will adopt the new disclosures required by SFAS No. 131 for the
year ending December 31, 1998. State Street does not expect its current
disclosures to change significantly under SFAS No. 131.
 
  Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" was issued in March 1998. State Street
will adopt this standard effective January 1, 1999. Management is currently
evaluating the impact of this statement.
 
  On June 16, 1998, SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" was issued. This statements requires companies to record
the fair value of derivatives on the balance sheet as assets or liabilities,
measured at fair value. Fair market valuation adjustments for derivatives
meeting hedge criteria will be recorded in either comprehensive income or
earnings, depending on their classification. Derivatives used for trading
purposes will continue to be marked to market through earnings. This statement
is effective for fiscal years beginning after June 15, 1999. Management is
currently evaluating the impact of this statement.
 
  In the opinion of management, all adjustments consisting of normal recurring
accruals, which are necessary for a fair presentation of the financial
position of State Street and subsidiaries at June 30, 1998 and December 31,
1997, and its cash flows and consolidated results of its operations for the
three and six months ended June 30, 1998 and 1997, have been made. These
statements should be read in conjunction with the financial statements and
other information included in State Street's latest annual report on form 10-
K.

for-sale securities. During the six months ended June 30, 1997, there were
less than $1 million of gross gains and losses realized on the sales of $173
million of available-for-sale securities.
 
NOTE C--ALLOWANCE FOR LOAN LOSSES
 
  The allowance for loan losses is maintained at a level believed adequate by
management to absorb estimated probable credit losses. Management's periodic
evaluation of the adequacy of the allowance for loan losses is based on State
Street's past loan loss experience, known and inherent risks in the portfolio,
current economic conditions and adverse situations that may affect the
borrowers' ability to repay, timing of future payments, estimated value of any
underlying collateral, and the performance of individual credits in relation
to contract terms and other relevant factors. The provision for loan losses
charged to earnings is based upon management's judgment of the amount
necessary to maintain the allowance at a level adequate to absorb estimated
probable credit losses.
 
  Changes in the allowance for loan losses were as follows:

(1) The regulatory designation of "well capitalized" under prompt corrective
    action regulations is not applicable to bank holding companies (State
    Street). Regulation Y defines well capitalized for bank holding companies
    (State Street) for the purpose of determining eligibility for a
    streamlined review process for acquisition proposals. For such purposes,
    qualifying as well capitalized requires a minimum Tier 1 risk-based
    capital ratio of 6% and a minimum total risk-based capital ratio of 10%.
 
(2) Effective January 1, 1998, regulatory capital standards require the
    addition of market risk equivalent assets to total risk based assets.

(UNAUDITED)
 
 
NOTE K--COMMITMENTS AND CONTINGENT LIABILITIES
 
  State Street provides banking, global custody, investment management,
administration and securities processing services to both U.S. and Non U.S.
customers. Assets under custody and assets under management are held by State
Street in a fiduciary or custodial capacity and are not included in the
Consolidated Statement of Condition because such items are not assets of State
Street. Management conducts regular reviews of its responsibilities for these
services and considers the results in preparing its financial statements. In
the opinion of management, there are no contingent liabilities at June 30,
1998, that would have a material adverse effect on State Street's financial
position or results of operations.
 
  State Street is subject to pending and threatened legal actions that arise
in the normal course of business. In the opinion of management, after
discussion with counsel, these can be successfully defended or resolved
without a material adverse effect on State Street's financial position or
results of operations.
 
NOTE L--OFF-BALANCE SHEET FINANCIAL INSTRUMENTS, INCLUDING DERIVATIVES
 
  State Street uses various off-balance sheet financial instruments, including
derivatives, to satisfy the financing and risk management needs of customers,
to manage interest rate and currency risk and to conduct trading activities.
In general terms, derivative instruments are contracts or agreements whose
value can be derived from interest rates, currency exchange rates and/or other
financial indices. Derivative instruments include forwards, futures, swaps,
options and other instruments with similar characteristics. The use of these
instruments generate fee, interest or trading revenue. Associated with these
instruments are market and credit risks that could expose State Street to
potential losses. State Street uses derivative financial instruments in
trading and balance sheet management activities.
 
  A table which summarizes the contractual or notional amounts of significant
derivative financial instruments held or issued by State Street is as follows:

contracts in a payable position are shown in other liabilities.
 
  Credit-related financial instruments include commitments to extend credit,
standby letters of credit, letters of credit and indemnified securities lent.
The maximum credit risk associated with credit-related financial instruments
is measured by the contractual amounts of these instruments. A summary of the
contractual amount of State Street's credit-related, off-balance sheet
financial instruments is as follows:

  On behalf of its customers, State Street lends their securities to
creditworthy brokers and other institutions. In certain circumstances, State
Street may indemnify its customers for the fair market value of those
securities against a failure of the borrower to return such securities. State
Street requires the borrowers to provide collateral in an amount equal to or
in excess of 102% of the fair market value of the securities borrowed. The
borrowed securities are revalued daily to determine if additional collateral
is necessary. State Street held, as collateral, cash and U.S. Government
securities totaling $69 billion and $59 billion for indemnified securities on
loan at June 30, 1998 and December 31, 1997, respectively.
 
  Loan and letter-of-credit commitments are subject to the same credit
policies and reviews as loans on the balance sheet. Collateral, both the
amount and nature, is obtained based upon management's assessment of the
credit risk. Approximately 67% of the loan commitments expire in one year or
less from the date of issue. Since many of the extensions of credit are
expected to expire without being drawn upon, the total commitment amounts do
not necessarily represent future cash requirements.

                    INDEPENDENT ACCOUNTANTS' REVIEW REPORT
 
The Stockholders and Board of Directors
State Street Corporation
 
  We have reviewed the accompanying consolidated statement of condition of
State Street Corporation (State Street) as of June 30, 1998, and the related
consolidated statements of income for the three-month and six-month periods
ended June 30, 1998 and 1997, and the statements of cash flows and changes in
stockholders' equity for the six month periods ended June 30, 1998 and 1997.
These financial statements are the responsibility of State Street's
management.
 
  We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures
to financial data, and making inquiries of persons responsible for financial
and accounting matters. It is substantially less in scope than an audit
conducted in accordance with generally accepted auditing standards, which will
be performed for the full year with the objective of expressing an opinion
regarding the financial statements taken as a whole. Accordingly, we do not
express such an opinion.
 
  Based on our reviews, we are not aware of any material modifications that
should be made to the accompanying consolidated financial statements referred
to above for them to be in conformity with generally accepted accounting
principles.
 
  We have previously audited, in accordance with generally accepted auditing
standards, the consolidated statement of condition of State Street Corporation
as of December 31, 1997 (presented herein), and the related consolidated
statements of income, cash flows and changes in stockholders' equity for the
year then ended (not presented herein), and in our report dated January 13,
1998, we expressed an unqualified opinion on those consolidated financial
statements.

TOTAL REVENUE
 
  Total revenue for the quarter was $681 million, up $113 million, or 20%,
from a year ago, reflecting growth in all lines of business. Total revenue is
comprised of fee revenue and net interest revenue. For the six months ended
June 30, 1998, total revenue was $1.3 billion, up $226 million, or 21%, from
1997, due to growth in both fee revenue and net interest revenue.

FEE REVENUE
 
  Fee revenue, which comprised 72% of total revenue for the quarter, was $493
million, up 22% from a year ago.
 
  Fiduciary compensation, the largest component of fee revenue, is generated
by services for institutional investors and investment management. Fiduciary
compensation was $380 million for the quarter, up $72 million, or 23%, from a
year ago. This increase was driven by expanded and new customer relationships.
 
  Services for institutional investors, which include accounting, custody,
record-keeping and information services, reflected broad-based growth. Total
assets under custody at June 30, 1998 increased 31% from a year ago to $4.5
trillion. Using broad assumptions, management estimates that approximately 50%
of the increase was due to the impact of higher securities market values, and
50% was due to additional contributions to mutual funds, pension plans and
other portfolios and to new business.
 
  Revenue from mutual funds reflected new business from both existing
customers and new customers and asset growth. Total mutual fund assets under
custody at June 30, 1998 increased 35% with year-over-year growth in both U.S.
and non-U.S. assets. Revenue from servicing offshore funds and from mutual
fund administration reflected strong growth.
 
  Revenue from servicing U.S. pension plans increased primarily due to new
business reflecting growth in portfolio accounting and custody services and
securities lending services.
 
  Outside the United States, revenue growth was driven by additional business
from existing customers and from new customers. Assets under custody for non-
U.S. customers at June 30, 1998 increased 22% from a year ago.
 
  Revenue from investment management, delivered through State Street Global
Advisors, reflected growth across all services--investment management for
institutional investors, record-keeping and investment services for defined
contribution plans, and investment services for high-net-worth individuals.
Revenue from managing assets for institutional investors was driven primarily
by new relationships, additional contributions from existing customer equity
and higher securities values. Total assets managed increased 29% from a year
ago to $459 billion, with about 50% of this growth due to additional funding
from customers and new customers and the remainder due to increased market
values.
 
  Foreign exchange trading revenue was $67 million in the quarter, up $17
million from a year ago. The higher level of foreign exchange revenue is the
result of both new business worldwide and active currency markets. New
business is attributable to State Street's on-line research, trade execution
and trade confirmation services, which are encouraging existing customers to
expand relationships and attracting new customers. The volume of trades, as
measured in dollars, increased 24% from a year ago. Foreign exchange trading
revenue was down slightly from the first quarter of 1998 as major currencies
were less volatile.
 
  Servicing and processing fee revenue was $40 million in the quarter,
compared to $39 million a year ago. Excluding the impact of revenue from a
non-strategic business which was sold in the second quarter of 1997, servicing
and processing revenue in the quarter increased 17% from a year ago. This
increase was driven by maintenance and brokerage services and revenue from
software licensing.
 
  For the six months ended June 30, 1998, fee revenue was $956 million, up
$178 million, or 23% from a year ago. Fiduciary compensation increased $133
million, or 22%. Foreign exchange trading revenue increased $46 million, or
48%, due to new business and active currency markets.

NET INTEREST REVENUE
 
  Taxable equivalent net interest revenue for the second quarter was $192
million, up $25 million, or 15%, from a year ago due primarily to a $9
billion, or 30%, increase in average interest-earning assets. State Street
uses its balance sheet to support the needs of institutional investors. These
customers, in conjunction with their worldwide investment activities, made
increased use of securities sold under repurchase agreements and deposits,
which were invested primarily in low-risk assets by State Street. Strong
growth in average non-U.S. deposits, up $3.4 billion, or 28%, and securities
sold under repurchase agreements, up $3.2 billion, or 34%, contributed
importantly to the revenue increase.

- --------------------------------------------------------------------------------
 
  For the six months ended June 30, 1998, taxable equivalent net interest
revenue was $378 million, up $51 million, or 15%, from the same period in 1997
due to a $7.9 billion, or 27%, increase in average interest-earning assets.
The growth in average interest-earning assets was driven primarily by a $3.5
billion, or 31%, increase in non-U.S. deposits and a $2.4 billion, or 25%,
increase in securities sold under repurchase agreements.
 
OPERATING EXPENSES
 
  Operating expenses for the quarter were $507 million, up $88 million, or
21%, from the second quarter of 1997, supporting business expansion and
investments in capabilities and capacity for future growth, and reflecting
acquisitions. Salaries and employee benefits in the quarter were $294 million,
up $60 million, or 25%, due to increased staffing and acquisitions. The
increases in staffing and business growth also contributed to the 40% increase
in equipment expense, which was $53 million for the quarter, and the 20%
increase in occupancy expense, which was $35 million for the quarter.
 
  For the six-month period ended June 30, 1997, operating expenses were up
$171 million, or 21%, due primarily to increased salaries and employee
benefits costs.
 
Resolution 2000
 
 
  The approaching Year 2000 presents companies in all industries with a myriad
of challenges to ensure compliance of their systems and processes. These
challenges stem from a once-common programming standard using two-digit years
for date fields contained in computer programs and related data. Commencing in
1996, State Street assessed the impact of the upcoming Year 2000 on it
operations and has developed a comprehensive program, Resolution 2000, to
address the related issues. This program includes a review of information
technology, mainframe, midrange and desktop applications, facilities and third
party providers and a plan for necessary remediation and testing. Third
parties include depositories, clearing and settlement locations, business
partners, counterparties, customers and vendors/suppliers. In essence, the
plan covers all parties involved in products and services provided by State
Street.
 
  A central program management office, global compliance teams and a corporate
governance/oversight structure support State Street's Resolution 2000 program.
Program updates, progress reports and critical matters are regularly
communicated to senior management and the Board of Directors. State Street's
goal is to modify and complete internal testing of its core information
technology and critical business supported software applications for Year 2000
compliance by December 31, 1998. State Street also intends to have the
necessary infrastructure to support point-to-point testing with external
parties and have non-critical desktop applications and facility systems
remediated and tested by December 31, 1998.

PART I. ITEM 2
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
(CONTINUED)
 
  Formal communications have commenced with external parties, requesting from
them the status of their Year 2000 compliance relating to products, services
and critical information provided to State Street. For example, questionnaires
have been issued to subcustodians focusing on the adequacy of their compliance
programs and implementation plans, including testing with State Street.
Responses have been received from subcustodians and the scope of testing is
currently being assessed. In addition, ongoing assessments of Year 2000
compliance have been incorporated into the existing due diligence procedures
performed routinely by State Street personnel in connection with their daily
activities. Similar activities, where necessary, are taking place with all
other third party providers.
 
  State Street cannot control the success of each external party's Year 2000
compliance program. However, contingency plans will be established wherever
possible to minimize risks of third party compliance failure. The ultimate
goal of these activities is to have an uninterrupted flow of information
between State Street and third party providers in the Year 2000 and beyond.
 
  Management currently estimates the aggregate cost of the Resolution 2000
program will be less than $200 million for the five-year period 1996-2000.
These costs are expensed as incurred and include staff, equipment, consultants
and other expenses. Such costs are expected to be less than 2% of total
operating expenses for the five-year period.
 
 
 European Economic and Monetary Union
 
  State Street has developed and is currently implementing a plan to service
customer accounting and other needs relating to the adoption by certain
members of the European Economic and Monetary Union of a common currency, the
euro. Management estimates that the costs to State Street associated with the
phase in of and ultimate redenomination to the euro will not be material.
 
CREDIT QUALITY
 
  At June 30, 1998, total loans were $6.0 billion. In the second quarter, the
provision for loan losses charged against income was $4 million, up from $3
million a year ago. During the quarter, the allowance for loan losses
increased from $89 million to $93 million; net recoveries were less than $1
million, versus recoveries of $1 million in the year earlier period. During
the second quarter, non-performing loans increased from $4 million to $9
million.
 
TAXES
 
  Taxes in the quarter were $55 million, up from $44 million a year ago. The
effective tax rate was 33.8%, up from 32.5% in the second quarter of 1997.

 Services for Institutional Investors
 
  Services for institutional investors include accounting, custody, daily
pricing and information services for large portfolios of investment assets.
Customers include mutual funds and other collective investment funds,
corporate and public pension plans, corporations, investment managers, non-
profit organizations, unions, and other holders of investment assets.
Institutional investors are offered other State Street services, including
foreign exchange, cash management, securities lending, fund administration,
record keeping, credit services, and deposit and short-term investment
facilities. These services support institutional investors in developing and
executing their strategies, enhancing their returns, and evaluating and
managing risk. Revenue from this line of business comprised 72% of State
Street's total revenue for the six months ended June 30, 1998.
 
  Revenue for the six months ended June 30, 1998 increased to $954 million, up
$162 million or 20% from $792 million in 1997. The $162 million increase in
revenue resulted from increased cross-border investment activity, the
installation of new business and expanding relationships with customers, who
are growing and using more services. Fee revenue was up 23%. This reflected
strong growth in revenue from accounting, custody and other services for
mutual funds, U.S. pension plans, and customers outside the U.S. Foreign
exchange trading revenue was up substantially. Net interest revenue, up 15%,
reflected additional funding from customers in conjunction with their
worldwide investment activities.
 
  Operating expenses for the six months ended June 30, 1998 were $717 million,
19% higher than a year ago, due to business growth and investments for future
growth, and reflecting acquisitions. Operating profit was $237 million, an
increase of $46 million, or 24%, from a year ago and reflected strong revenue
growth.
 
 Investment Management
 
  State Street manages financial assets worldwide for both institutions and
individuals and provides related services, including participant record-
keeping for defined contribution plans. Investment management features a broad
array of services, including passive and active equity, money market, and
fixed income strategies. Revenue from this line of business comprised 19% of
State Street's total revenue for the first six months of 1998.
 
  Revenue grew 25% to $253 million for the six months ended June 30, 1998 due
to revenue growth across the product line. Operating expenses increased 31%
reflecting additional staff to support business growth and the acquisition of
the outstanding ownership of a joint venture previously accounted for using
the equity method. Operating profit was $40 million, unchanged from the six
months ended June 30, 1997.
 
 Commercial Lending
 
  Reported in this line of business are loans and other banking services for
regional middle-market companies, for companies in selected industries
nationwide, and for broker/dealers. Other credit services include leasing and
international trade finance. Revenue from this line of business comprised 9%
of State Street's total revenue for the first six months of 1998.
 
  Revenue grew to $118 million for the six months ended June 30, 1998, up 12%
from $105 million from a year ago, due primarily to 20% increase in loans.
Loans to New England businesses, specialty industries nationwide, leases, and
international trade finance all grew.
 
  Operating expenses increased 9% for the six months ended June 30, 1998,
supporting business growth. Operating profit was $67 million, an increase of
$9 million, or 16% from 1997.

PART I. ITEM 2.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
(CONTINUED)
 
 Capital and Liquidity
 
  State Street ensures it is well capitalized in order provide financial
flexibility which facilitates funding corporate growth and other business
needs and to support its customers.
 
 Capital
 
  As a state chartered bank and member of the Federal Reserve System, State
Street Bank, State Street's principal subsidiary, is regulated by the Federal
Reserve Board which has established guidelines for minimum capital ratios.
State Street has developed internal capital-adequacy policies to ensure that
the Bank meets or exceeds the level required for the "well capitalized"
category, the highest of the Federal Reserve Board's five capital categories.
State Street's capital management emphasizes risk exposure rather than simple
asset levels. At 12.4%, the Bank's Tier 1 risk-based capital ratio
significantly exceeds the regulatory minimum of 4%. See Note E to the
Consolidated Financial Statements for further information. State Street
purchased 210,000 shares of its stock during the second quarter of 1998. As of
June 30, 1998, the Board of Directors of State Street authorized the purchase
of an additional 2.5 million shares.
 
  In May 1998, State Street issued $150 million of 30 year floating rate
Capital Securities. See Note D to the Consolidated Financial statements for
further information.
 
 Liquidity
 
  The primary objective of State Street's liquidity management is to ensure
that it has sufficient funds to meet its commitments and business needs,
including accommodating the transaction and cash management requirements of
its customers. Liquidity is provided by State Street's access to global debt
markets, its ability to gather additional deposits from its customers,
maturing short-term assets, the sale of securities and payments of loans.
Customer deposits and other funds provide a multi-currency, geographically-
diverse source of liquidity.
 
  State Street maintains a large portfolio of liquid assets. At June 30, 1998,
State Street's liquid assets were 76% of total assets.
 
TRADING ACTIVITIES: FOREIGN EXCHANGE AND INTEREST RATE SENSITIVITY
 
  As part of its trading activities, the Corporation assumes positions in both
the foreign exchange and interest rate markets by buying and selling cash
instruments and using financial derivatives, including forward foreign
exchange contracts, foreign exchange and interest rate options, and interest
rate swaps. As of June 30, 1998, the notional amount of these derivative
instruments was $120.6 billion, of which $118.8 billion was foreign exchange
forward contracts. Long and short foreign exchange forward positions are
closely matched to minimize currency and interest rate risk. All foreign
exchange contracts are valued daily at current market rates.
 
  The corporation uses a variety of risk measurement and estimation techniques
including value at risk. Value at risk is an estimate of potential loss for a
given period of time within a stated statistical confidence interval. State
Street estimates value at risk daily for all material trading positions using
a methodology based on the distribution of historical market movements. The
Corporation has adopted standards for estimating value at risk, and maintains
capital for market risk, in accordance with the Federal Reserve's Capital
Adequacy Guidelines for market risk. Value at risk is estimated for a 99% one-
tail confidence interval and an assumed one-day holding period using an
historical observation period of one year. A 99% one-tail confidence interval
implies that daily trading losses should not exceed the estimated value at
risk more than 1% of the time, or approximately three days out of the year.
The methodology takes into account observed correlations between interest
rates and foreign exchange rates, and the resulting diversification benefits
provided from the mix of the corporation's trading positions.

PART I. ITEM 2.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
(CONTINUED)
 
  Like all quantitative measures, value at risk is subject to certain
limitations and assumptions inherent to the methodology. State Street's
methodology uses an assumption of normal distribution of market returns. The
estimate is calculated using static portfolios consisting of positions held at
the end of the trading day in Boston. Implicit in the estimate is the
assumption that no intraday action is taken by management during adverse
market movements. As a result, the methodology does not represent risk
associated with intraday changes in positions or intraday price volatility.
 
  The following table presents State Street's market risk for its trading
activities as measured by its value at risk methodology:
 
VALUE AT RISK FOR JUNE 30, 1998

- -------------------------------------------------------------------------------
 
  State Street compares actual daily profit and losses from trading activities
to estimated one-day value at risk. During the second quarter of 1998, State
Street did not experience any foreign exchange trading loss in excess of its
end of day value at risk estimate.
 
FACTORS AFFECTING FUTURE RESULTS
 
  From time to time, information provided by State Street, statements made by
its employees, or information included in its filings with the Securities and
Exchange Commission (including this Form 10-Q), may contain statements which
are not historic facts (so-called "forward looking statements"), including
statements about the Corporation's confidence and strategies and its
expectation about revenues and market growth, new technologies, services and
opportunities, and earnings. These statements may be identified by such
forward looking terminology as "expect", "look", "believe", "anticipate",
"may", "will", or similar statements or variations of such terms. These
forward-looking statements involve certain risks and uncertainties which could
cause actual results to differ materially. Factors that may cause such
differences include, but are not limited to, the factors discussed in this
section and elsewhere in this Form 10-Q. Each of these factors, and others,
are also discussed from time to time in the Corporation's other filings with
the Securities and Exchange Commission, including its report on Form 10-K.
 
  Cross-border investing. Cross-border investing by customers worldwide
benefits State Street's revenue. Future revenue may increase or decrease
depending upon the extent of cross-border investments made by customers or
future customers.
 
  Savings rate of individuals. State Street benefits from the savings of
individuals that are invested in mutual funds or defined contribution plans.
Changes in savings rates or investment styles may affect revenue.
 
  Value of worldwide financial markets. As worldwide financial markets
increase or decrease in value, State Street's opportunities to invest and
service financial assets may change. Since a portion of the Corporation's fees
are based on the value of assets under custody and management, fluctuations in
worldwide securities market valuations will affect revenue.
 
  Dynamics of markets served. Changes in markets served, including the growth
rate of U.S. mutual funds, the pace of debt issuance, outsourcing decisions,
and mergers, acquisitions and consolidations among customers and competitors
can affect revenue. In general, State Street benefits from an increase in the
volume of financial market transactions serviced.
 
  State Street provides services worldwide. Global and regional economic
factors and changes or potential changes in laws and regulations affecting the
Corporation's business, including changes in monetary policy, could also
affect results of operations.

PART I. ITEM 2.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
(CONTINUED)
 
  Interest rates. Market interest rate levels, the shape of the yield curve
and the direction of interest rate changes affect both net interest revenue
and fiduciary compensation from securities lending. In a stable rate
environment, State Street benefits from high interest rates, because it has a
larger amount of interest-earning assets than interest-bearing liabilities,
and from a steeper curve. All else being equal, in the short term State Street
benefits from falling interest rates and is negatively affected by rising
rates because interest-bearing liabilities re-price sooner than interest-
earning assets.
 
  Volatility of currency markets. The degree of volatility in foreign exchange
rates can affect the amount of foreign exchange trading revenue.
 
  Pace of pension reform. State Street expects to benefit from worldwide
pension reform that creates additional pools of assets that use custody and
related services and investment management services. The pace of pension
reform may affect the pace of revenue growth.
 
  Pricing/competition. Future prices the Corporation is able to obtain for its
products may increase or decrease from current levels depending upon demand
for its products, its competitors' activities, and the introduction of new
products into the marketplace.
 
  Pace of new business. The pace at which existing and new customers use
additional services and assign additional assets to State Street for
management or custody will affect future results.
 
  Business mix. Changes in business mix, including the mix of U.S. and non-
U.S. business, will affect future results.
 
  Rate of technological change. Technological change creates opportunities for
product differentiation and reduced costs, as well as the possibility of
increased expenses. State Street's financial performance depends in part on
its ability to develop and market net and innovative services and to adopt or
develop new technologies that differentiate State Street's products or provide
cost efficiencies.
 
  Year 2000 issues. The costs and projected completion date of State Street's
Resolution 2000 program are estimates. Factors that may cause material
differences in actual results include the availability and cost of systems and
personnel, non-compliance of third-party providers (including customers), and
similar uncertainties. State Street's businesses are substantially dependent
upon its data processing software and hardware systems and upon its ability to
process information on its customers' behalf. If the Corporation were unable
to process information as a result of the Year 2000 issues, despite State
Street's efforts and its contingency planning, such a failure could have a
materially adverse effect on State Street's business, as could Year 2000
problems experienced by others with whom the Corporation does business.
 
  Acquisitions and alliances. Acquisitions of complementary businesses and
technologies and strategic alliances are an active part of State Street's
overall business strategy, and the Corporation has completed several
acquisitions in recent years. However, there can be no assurance that
services, technologies, key personnel, and businesses of acquired companies
will be effectively assimilated into State Street's business or service
offerings or that alliances will be successful.

ITEM 5. OTHER INFORMATION
 
 Discretionary Voting Authority--Advance Notice Requirement
 
  Under the Federal proxy rules applicable to the solicitation of proxies for
the 1999 Annual Meeting of Stockholders, a stockholder who wishes to present a
proposal at the 1999 Annual Meeting for inclusion in the Company's proxy
materials for that meeting must submit the proposal to the Secretary of the
Company on or before November 10, 1998 for inclusion in the Company's proxy
materials. In addition, if a stockholder who wishes to present at the 1999
Annual Meeting a proposal that will not be included in the Company's proxy
materials fails to notify the Company by February 15, 1999 of the proposal,
then the proxies solicited by management with respect to the 1999 Annual
Meeting will confer discretionary voting authority with respect to the
stockholder's proposal, in the event it is properly brought before the Meeting
notwithstanding the requirements of the Company's By-laws, on the persons
selected by management to vote the proxies.
 
  Under the Company's By-laws, proposals of business and nominations for
directors--other than those to be included in the Company's proxy materials--
may be made by a stockholder of record entitled to vote at the Meeting if
notice is timely given under, and if the notice contains the information
required by, the By-laws. Except as noted below, to be timely under the By-
laws, a notice with respect to the 1999 Annual Meeting must be delivered to
the Secretary of the Company no earlier than January 15, 1999 and no later
than February 15, 1999, unless the date of the 1999 Annual Meeting is advanced
by more than 30 days or delayed by more than 60 days from the anniversary date
of the 1998 Annual Meeting, in which event the By-laws provide different
notice requirements. In the event the Board of Directors nominates a New
Nominee (as defined), a stockholder's notice shall be considered timely if
delivered not later than the 10th day following the date on which public
announcement (as defined) is first made of the election or nomination of such
New Nominee. This By-law advance notice requirement is in addition to the
notice requirement for discretionary proxies contained in the Federal proxy
rules.
