                      ANNUAL REPORT
                      JULY 31, 1998
<PAGE>
 
Dear Fellow Shareholders,
 
   We are pleased to report that for the 12 months ended July 31, 1998, the
Domini Institutional Social Equity Fund rose 22.74%, while the Standard &
Poor's 500 rose 19.34%./1/
 
   As a socially responsible index fund, our fund attempts to reflect the per-
formance of the market for U.S. equities that a social investor might invest
in. During the past 12 months, our portfolio benefited from several broad mar-
ket trends, but most importantly from an investing public seeking companies
with greater earnings predictability as the fiscal crisis in the Pacific Rim
began to be felt by our own markets. We also benefited from our avoidance of
tobacco stocks and emphasis on companies that produce consumer goods. These
past 12 months have been volatile and difficult for investors, as compared to
the prior fiscal year. Nonetheless, both the market and our fund enjoyed total
returns to qualify this as another prosperous year.
 
   Each year our annual report to shareholders provides me with an opportunity
to review both new trends in the field of socially responsible investing, and
our response to them. This year we will be profiling several smaller companies
with particularly innovative policies. We choose to share these stories with
you as a means of communicating an important emerging facet of socially re-
sponsible investing--the search for leaders.
 
   Increasingly, socially responsible investing is being recognized for its
vital role as a strategic building block in the larger, corporate accountabil-
ity debate. Using our investment dollars, we build the research infrastructure
that continuously evaluates and reevaluates the impact of corporate behavior
on society. As shareholders, we own many of the mightiest companies on the
planet and we maintain a regular dialogue with them in order to produce a com-
prehensive benefit not only for ourselves, but for all stakeholders. These
stakeholders include customers, communities, suppliers and the natural envi-
ronment in which we live.
 
   Over the past several years a dynamic new voice has been raised that high-
lights an additional role for social investors to play. Our shareholders,
along with other socially responsible investors and, perhaps most importantly,
corporations, are seeking models in companies that in some way provide ex-
traordinary examples of what a corporation can do. Many American companies can
point with pride to the forward looking policies they have initiated, creating
value for their stakeholders while also enhancing their corporate missions and
even their bottom lines. But it is in smaller companies that the dramatic im-
pact of model corporate behavior can best be seen.
 
   It is my own belief that a just and sustainable economic system can and
must exist if my children's children are to be allowed to age with grace. Re-
sponsible management teams will
<PAGE>
 
continuously find ways to improve, but models help us all to recognize what
can be done. We are pleased to share with you some particularly interesting
programs some of our portfolio's smaller companies have in place.
 
   The year ending July 31, 1998 was an exciting one for the Domini Institu-
tional Social Equity Fund. Our shareholders continued to tell friends and fam-
ilies about us in record numbers. Our message, one of increased corporate re-
sponsibility, has continued to spread. Your validation of our recommendation
to create a new management company has allowed us to move to a whole new level
of shareholder servicing, outreach and advocacy. Thank you for your decision
to become a member of the Domini Institutional Social Equity Fund family. We
look forward to serving you throughout the years ahead.
 
   Very truly yours,

/1/The performance information quoted represents past performance and is not
   indicative of future results. Average annual total return for the Domini
   Institutional Social Equity Fund for the five year period and the period
   since inception (6/3/91) as of July 31, 1998 was 23.07% and 19.03%,
   respectively. Average annual total return for the S&P 500 for the five year
   period and the period since the Fund's inception (6/3/91) as of July 31,
   1998 was 22.89% and 18.80%, respectively. The S&P 500 Index is an unmanaged
   index used to portray the pattern of common stock movement based on the
   average performance of 500 widely held common stocks and does not pay
   expenses. An investment cannot be made directly in an index. Return and
   principal value of an investment will fluctuate so that an investor's
   shares, when redeemed, may be worth more or less than their original cost.

  All the companies whose stock is held in the Domini Social Index Portfolio
("DSIP") meet multiple standards for corporate accountability. We avoid compa-
nies in the business of manufacturing alcohol and tobacco products as well as
those that provide gambling services or equipment. We seek to avoid companies
that sell weapons or are in the nuclear power industry. In addition, we evalu-
ate a company's social profile by weighing both strengths and weakness in the
areas of community impact, employee relations, the environment, product safety
and usefulness, non-U.S. operations and diversity.
 
  The following sampling of some of the smaller companies in our portfolio
highlights some impressive achievements in the areas of community impact, em-
ployee relations, the environment, diversity and product safety and useful-
ness.
 
COMMUNITY
 
  We seek companies with innovative and generous charitable giving programs
with a particular emphasis on programs promoting economic and social justice.
In evaluating the level of a firm's generosity, we look for companies that
have consistently given over 1.5% of trailing three-year net earnings before
taxes to charity, or have otherwise been notably generous in their giving.
 
  GRACO, INC. manufactures and markets a wide range of fluid handling products
for the industrial and commercial markets, including specialized pumps, regu-
lators, valves, atomizing devices, and painting and cleaning equipment. In
Fiscal Year ("FY") 1997, the company donated 2.44% ($1,300,000) of trailing
three-year net earnings before taxes (NEBT) to charity. Graco has a stated
goal of contributing 5% of U.S. pretax profits in cash and in-kind giving to
charity each year, focusing on human services in communities where the company
has facilities. In the mid-1970s, David Koch, Graco's former CEO, and a cur-
rent member of Graco's Board, was instrumental in creating the Minnesota 5%
Club. Corporations that join the club pledge to contribute 5% of pretax prof-
its to charity each year. The 5% club was one of the first of its kind in the
U.S. and has served as a model for similar organizations in other cities and
states. As of July 31, 1998, Graco, Inc. represented .014% of the DSIP.
 
  OSHKOSH B'GOSH manufactures and markets children's clothing and work apparel
for adults. In FY 1996, the company donated 2.4% ($340,000) of average trail-
ing three-year net earnings before taxes (NEBT) to charity. In FY 1997, the
company made $350,000 in cash gifts to charity. Oshkosh B'Gosh's charitable
giving program focuses on children. In February 1998, the company told Kinder,
Lydenberg, Domini & Co. ("KLD") that in FY 1997 it supported the Boys and
Girls Club, the Child Welfare League of America, and Kids in Distressed Situa-
tions (KIDS). The company's CEO Doug Hyde is a past president of KIDS. The
company also told KLD that it donated approximately 25,000 garments to chari-
table organizations, including KIDS. As of July 31, 1998, Oshkosh B'Gosh rep-
resented .008% of the DSIP.
 
  UNITED AMERICAN HEALTHCARE CORPORATION provides management and consulting
services, primarily to health maintenance organizations (HMOs) owned by the
company in Michigan, Tennessee, and Florida. In Michigan and Tennessee its op-
erations are known primarily as Omnicare Health Care. In Florida the firm op-
erates Ultramedix Healthcare Systems and United American of Florida. The com-
pany primarily serves Medicaid recipients and was among the companies that pi-
oneered the development of cost control and management for Medicaid services.
One of the firm's fundamental business strategies is to reduce health care
costs by providing preventative and home health care services to the economi-
cally disadvantaged. As of November 1997, four of the company's five senior
line executives were African Americans, including the CEO.
 
  The firm has endowed the United American Healthcare Foundation, established
to encourage minorities to enter the medical profession. In FY 1995, 1996, and
1997 the company contributed $150,000 to
 
                                       3
<PAGE>
 
the foundation. At several universities around the country, including Wayne
State and Morehouse, the Foundation has funded five full four-year scholar-
ships for minority students hoping to become doctors or registered nurses.
United American is also a strong supporter of African American art. For its
corporate headquarters, through 1996, it had purchased approximately $250,000
in art by contemporary African American artists. In the past, the firm has
sponsored numerous volunteer programs in inner city Detroit and donates to
other charities including the March of Dimes, the American Red Cross, and the
Detroit Institute of Art. As of July 31, 1998, United American Healthcare Cor-
poration represented .001% of the DSIP.
 
  WHOLE FOODS MARKET, INC. owns and operates natural foods supermarkets in 17
states, operating under the names Whole Foods Market, Fresh Fields, Bread and
Circus, and Wellspring Grocery. In FY 1995, the company donated approximately
8.11% ($790,000) of trailing three-year net earnings before taxes (NEBT) to
charity. This figure is up from $500,000 the previous year, due largely to the
company's increase in net income since 1993. In 1997, the company reported
that it donated approximately $1 million in combined cash and in-kind dona-
tions. The company has a policy to contribute a minimum of 5% of after-tax
earnings in cash and goods to charity each year. Charitable contributions are
made primarily at the store level so that they can directly benefit local com-
munity groups that make up the store's customer base. The company offers 20
hours of paid time-off per year for community service. Whole Foods has a "five
percent day" program whereby its stores designate a nonprofit organization to
receive 5% of the net sales of that day. Organizations supported include the
AIDS Action Committee, American Indian Family, Foundation for Children with
AIDS, Habitat for Humanity, National Museum of Women in Arts, New England Ani-
mal Action, Rainforest Action Network, and the Boston Coalition for Gay, Les-
bian, Bisexual & Transgendered Youth. Whole Foods is part of Chefs Collabora-
tive 2000, a national network of well-know chefs working to pro-
mote sustainable food choices. As part of the network, the company hosted a
tasting and demonstration series, proceeds of which will help make a video to
educate children regarding food, culture, and sustainable food choices. The
company's payroll deduction plan includes Environmental Fund of Texas, Another
Way, International Services Agencies, Black United Fund of Texas, United Way,
and others. As of July 31, 1998, Whole Foods Market, Inc. represented .029% of
the DSIP.
 
 
EMPLOYEE RELATIONS
 
  We seek companies with a commitment to worker involvement/ownership through
employee stock ownership, cash profit sharing and employee participation in
management decision-making. We also look for companies with histories of fair
labor negotiations and strong retirement benefits.
 
  BALDOR ELECTRIC COMPANY manufactures and markets electric motors and indus-
trial control systems, including electronic servo drives which can be pro-
grammed to control robotics and machine tools, and other products such as in-
dustrial grinders, buffers, and dental polishing lathes. In 1996 the board of
directors voted to expand the company's employee stock option grant program to
include all employees, not just salaried employees. Options were distributed
under the plan in 1997. The number of options granted each employee was based
on years of service. A March 1995 Forbes article commented that "Baldor is one
of those companies that do several things very well." In the article, chairman
Roland Boreham attributes Baldor's success to its employee training and qual-
ity programs. At the company's 1994 annual meeting, CEO R. L. Qualls stated
the company's goal is to provide one hour of training per week per employee.
Since 1992 the firm has spent an average of $677 per employee ($2 million) an-
nually for employee education and training. For employees lacking basic liter-
acy and math skills, Baldor provides education opportunities. Its goal is to
achieve 8th-grade-level skills for all its employees. In January 1998, Baldor
was included on Fortune magazine's
 
                                       4

list of "The 100 Best Companies to Work for in America." A 1992 Fortune maga-
zine article reported that in 1991, rather than lay off workers in a difficult
period of recession, the company went to four-day workweeks for seven weeks.
One of Baldor's plants was among those profiled in 1995 by the Department of
Labor's Best Practices Clearinghouse. The company's retirement program is
funded through a profit sharing plan that contributes 12% of Baldor's pretax
earnings to all participants based on compensation. In addition, the employees
may contribute to a 401(k) savings plan through which the firm matches 25% up
to 4% of compensation. As of March 1998, employees owned 10% of the company's
stock through the profit sharing and savings plans. As of July 31, 1998,
Baldor Electric Co. represented .016% of the DSIP.
 
  HANNAFORD BROS. CO. owns and operates supermarkets in New England under the
names Shop 'n Save and Hannaford Food and Drug Superstores. It also operates
the Wilson's Supermarkets chain of stores in Virginia, North Carolina, and
South Carolina, and a trucking and food distribution subsidiary. As of 1996,
the company distributed profits annually to executives and a substantial num-
ber of full time employees. This program pays out regularly and approximately
1,000 of its employees are eligible for the plan. At its retail stores, the
company has also instituted gainsharing programs, where a portion of costs
saved due to employee suggestions are passed on to employees. In 1990 the com-
pany pioneered a new team management philosophy whereby 120 employees work in
five teams virtually without management supervision. The firm has begun simi-
lar experiments at several of its retail supermarkets. Its new store in Con-
cord, New Hampshire, is run entirely by self-directed teams. The company of-
fers a variety of employee-involvement programs, as well as a "Customer
Counts" program that aims at promoting better customer service. Hannaford re-
cently began offering certain items in bulk quantities at its retail stores,
items priced at club store levels. Hannaford has an
associate referral program called "BreadWinner,"
which rewards employees for referring qualified candidates who are eventually
hired. In August 1996, the company stopped selling eggs from a large egg
producer in Maine, when it learned that the producer was facing a $3.6 million
OSHA fine for worker safety violations. As of July 31, 1998, Hannaford Bros.
Co. represented .037% of the DSIP.
 
  LUBY'S CAFETERIAS, INC. owns and operates 232 cafeterias in the southern
United States. Luby's has a cash profit sharing program available to all em-
ployees over the age of 21 and with at least one year of service. The firm's
contributions to this program are contingent on whether the company meets cer-
tain minimum net income standards. In FY 1997 and 1996, the company distrib-
uted $1.5 million and $5.1 million, respectively, under this plan. All compen-
sation for managers is based on profit. Although the company does not pay its
store managers a salary, it does guarantee a minimum salary. This program ena-
bles Luby's managers to earn far more than the industry's average wage: on av-
erage, in excess of $100,000 per year. The company reports that at some stores
bonuses tied to store performance extend down to hourly employees. The
company's notably autonomous restaurant managers set their own menus and are
responsible for hiring and training of employees. The company has a reputation
for promoting from within. Most of the company's senior management team was
drawn from its restaurant managers. In 1995 the company reported that it hired
169 employees from its management training program. The program is approxi-
mately three months long. One week is spent in class-room training at corpo-
rate headquarters and the remainder of the time in cafeterias. In 1995 the
firm created a series of "satellite" training schools at several cafeterias.
In 1996 it launched a program called Career 2000 to improve its management
training and human resources initiatives. The average Luby's manager has
worked for the company for 15 years. Of its 190 cafeteria managers in 1995,
156 had been with the company for at least ten years. As of July 31, 1998,
Luby's Cafeterias, Inc. represented .006% of the DSIP.

  NORTHWEST NATURAL GAS CO. (NNG) is principally engaged in the distribution
of natural gas (90% of FY 1996 revenues), a fuel with significant environmen-
tal advantages over oil and coal, to western Oregon, including the metropoli-
tan Portland area. The company also has investments in alternative energy pro-
jects, including wind, solar and hydroelectric power. NNG and the union repre-
senting its employees enjoy a uniquely stable and innovative relationship. In
March 1997, the union and the company agreed to a new collective bargaining
agreement, to last for seven years. Under the agreement, no regular employee
who was employed prior to April 1997 will be laid off, and benefits will be
maintained at the April 1997 level. The agreement continues a "joint accord"
partnership that began in 1989 and was renewed in 1992, which obligates labor
and management to create more flexible work rules, a more efficient workplace,
and to improve customer service. The company's last major strike was in 1977.
In 1989, the union negotiated Key Goals, a gainsharing plan for all bargaining
and nonbargaining employees (the firm now has a separate plan for nonbargain-
ing employees, based solely on profitability). Since 1995, the plan has had
five goal areas: profitability-utility earnings per share; customer satisfac-
tion based on survey results; return on new residential customers; productiv-
ity in serving customers; and market share. Each year the company reviews its
performance against set benchmarks within each of the goal areas and deter-
mines the award to be given to all employees. In 1996, all employees received
the maximum award of 5.5% of their base compensation. In 1997, all employees
received an award equal to almost 3% of their base compensation, representing
a total award of $2.76 million. In February 1998, the company told KLD that
the lower award was due to decreased profitability, which it attributed to
warmer weather.
 
  The company was profiled in 1995 by the Department of Labor's Best Practices
Clearinghouse. The company has union representation at the monthly executive
staff meeting, and union members constitute two thirds of the company's labor
relations team (LRT), which monitors employee issues on a daily basis. The
LRT, executives, and middle management representatives meet once a month to
discuss employee issues and share information on company activities. The min-
utes from these meetings are distributed to all employees within two days.
Data on company finances, customers, and general operations are shared with
employees. Information on the company's key goals, which measure customer sat-
isfaction, increased productivity, cost control, capital construction, and the
amount of earnings per share is shared with all employee work groups once a
month. NNG's CEO and president visits each of the company worksites once a
year to answer employee questions. The company also has a bimonthly newsletter
in which management answers anonymous questions submitted by employees. Em-
ployee teams from the LRT were involved in establishing the performance ap-
praisal system. In some of the company's departments all levels of employees
are allowed to participate in the interviewing of potential employees. For
substantially all of its employees, the company has a defined benefit pension
plan. In addition, its retirement options include a 401(k) savings plan
through which the firm matches in cash 50% of employee contributions up to 4%
of base compensation. As of July 31, 1998, Northwest Natural Gas Co. repre-
sented .013% of the DSIP.
 
ENVIRONMENT
 
  We seek companies that show respect for the natural environment. This may be
demonstrated by the product or service the firm provides or exhibited through
in-house recycling or pollution-prevention programs, gifts to conservation
groups, or other ways of conducting day-to-day business.
 
  W.H. BRADY CO. develops, manufactures and markets industrial identification
and safety products, and specialty coated materials. The company's industrial
and facility identification products include pipe and valve markers, wire
markers, computer printable labels, informational signs, and automatic
identifica-

tion and data collection systems. Safety and regulatory products include
safety signs, lockout/tagout products to meet OSHA regulations, and traffic
control products. The company also manufactures tapes for the data storage,
semiconductor, and audio/video industries. Katherine M. Hudson serves as the
company's president and chief executive officer.
 
  The company has taken steps to reduce emissions of volatile organic com-
pounds (VOCs) from its adhesive operations. It has reformulated some adhesives
to a water base and installed incineration equipment to burn other emissions,
destroying 96% to 99% of VOCs. In 1997 the company reported that it had re-
duced air emissions by 50% since 1990, and that 90% of its U.S. facilities use
the more environmentally friendly ultra-violet ink technologies rather than
solvent-based systems. Brady's generation of hazardous wastes was down by 30%
and of water-borne wastes by 80% from 1990 to 1993, while during the same pe-
riod its sales increased by 30%. As of July 31, 1998, W.H. Brady Co. repre-
sented .007% of the DSIP.
 
  CARAUSTAR INDUSTRIES, INC. is a manufacturer of paperboard products such as
tubes, cores, and composite containers, folding cartons, gypsum wallboard fac-
ing paper, specialty and paperboard products, injection-molded and extruded
plastics, and paperstock. The company's paper products are made from fiber re-
covered from recycled paper. The company has been recovering fiber from waste
paper since the 1930s. Recycled paper is its sole source of fiber. Caraustar
uses approximately 600,000 tons of waste paper per year. The company operates
a program through which it sells, leases, or furnishes baling machines to
small companies to bale their own paperstock for collection by the company. In
1997 Caraustar reported that it had not been named as a potentially responsi-
ble party for any hazardous waste sites or any Superfund sites. In 1997 the
company told KLD that it had no accrued liabilities for environmental
remediation. As of July 31, 1998, Caraustar Industries, Inc. represented .013%
of the DSIP.
  ENERGEN CORPORATION distributes natural gas in central and northern Alabama
through its Alagasco subsidiary. The company is also involved in natural gas
and oil exploration and production, primarily in Alabama, Louisiana, Texas,
and the Gulf of Mexico through its Taurus Exploration subsidiary. Taurus also
produces natural gas from coal-bed methane. Energen reports that since 1985,
it has acquired 22 municipal natural gas systems. The company derived 94% of
its FY 1997 revenues from natural gas, a fuel with significant environmental
advantages over oil and coal. The company has a fleet of compressed natural
gas (CNG) fueled vehicles. Through a joint venture with Sonat Ventures, Inc.,
the company will supply CNG to refueling stations and finance vehicle conver-
sion. The first station opened in Birmingham, Alabama, in December 1993. As of
July 31, 1998, Energen Corporation represented .010% of the DSIP.
 
  MODINE MANUFACTURING COMPANY manufactures heat transfer equipment, primarily
radiators for cars, trucks, and other vehicles, vehicular condensors and evap-
orators, oil coolers, charge air coolers, heating and cooling equipment for
buildings, and miscellaneous related products. The company's charge-air cool-
ers for large trucks cool air as it enters an engine's cylinders, helping fuel
to burn more efficiently and reducing emissions. The design of Modine's con-
denser in its automobile air conditioners reduces the amount of refrigerant
chlorofluorocarbons (CFCs) needed by 40%. It can also be used with new gases
that contain no CFCs. In 1996 the company began producing latent-heat batter-
ies which quickly warm engine fluids, reducing vehicle emissions produced
while running an engine to warm the motor. Between 1988 and 1994, the company
achieved an 83% reduction in emissions of toxic chemicals covered by the EPA's
voluntary "33/50" toxics reduction program, exceeding the EPA's 50% goal. As
of April 1996, the company had eliminated the use of 1,1,1, trichlorethane at
all its plants. As of January 1994, several plants had also eliminated the use
of naphtha, xylene, and toluene. The company has also reduced its emissions of
volatile organic compounds (VOCs)
 
                                       7
<PAGE>
 
by using powder paints that are applied electrostatically. In its aluminum
manufacturing, the firm uses the Nocolok technology licensed from Alcoa, which
reduces hazardous emissions to virtually zero. In 1991 Modine established a
waste minimization program, setting a company-wide goal of a 65% reduction by
1995. In March 1996, the company reported reductions of over 65% through cal-
endar year 1995. It also reported plans to improve its tracking of wastes
based on degree of toxicity. The company established similar programs at its
facilities in Canada and Mexico in 1996. In 1997 the company reported that it
regularly monitors and audits its facilities for environmental performance. In
addition, all its facilities have their own unique environmental programs with
commitments to one-and five-year goals. As of July 31, 1998, Modine Manufac-
turing Company represented .020% of the DSIP.
 
  THOMAS INDUSTRIES, INC. manufactures and markets lighting products, and com-
pressors and vacuum pumps. The company developed and manufactures a special-
ized pump used in vapor-recovery systems for gasoline fumes at pumping sta-
tions. The firm's compressors are used in vehicle emissions testing equipment
and other air quality measurement devices, as well as in freon recovery. The
company also makes leak detectors for monitoring underground fuel storage
tanks. Thomas participates in the EPA's Green Lights program to develop and
promote energy efficient lighting. The company is a manufacturer of energy ef-
ficient fixtures and controls, including a lighting system with sensors that
reduce light levels when an area is not in use. In cooperation with the U.S.
Department of Energy, Thomas publishes efficacy ratings and comparative yearly
lighting energy costs in its catalogue. Thomas has initiated reduction of its
use of toxic chemicals, including the elimination of ozone-depleting sub-
stances, from all its manufacturing facilities. The company publishes luminare
ratings regarding the energy efficiency of its lighting products. As of July
31, 1998, Thomas Industries, Inc. represented .005% of the DSIP.

ration's printed circuit fabrication operations. Deborah Coleman has served as
the company's CEO since it spun off from Tektronix as an independent company
in June 1994. Ms. Coleman has a history of success in the computer business.
In 1987 Apple Computer appointed her the
youngest chief financial officer in the Fortune 500. In 1992, after eleven
years at Apple, Ms. Coleman left to become vice president of materials opera-
tions at Tektronix where she served for two years before becoming CEO of
Merix. Two women serve among the company's four senior line executives. In ad-
dition to Ms. Coleman, Terri Timberland is vice president for human resources

goals, assists in recruiting, and monitors progress of Merix's diversity edu-
cation programs. In FY 1996, 25% of the company's officials and managers were

PRODUCT
 
  We seek companies that provide high quality products and are industry lead-
ers in research and development.
 
  DIONEX CORPORATION manufactures and markets analytical instruments includ-
ing: chromatography systems used to identify the components of chemical mix-
tures; bioseparation products; and supercritical fluid separations systems.
The company also makes automation systems for chemical analysis. Ion chroma-
tography (IC) accounts for the majority of the company's revenues. IC has a
wide range of environmental applications, including analysis of water quality,

  SCHOLASTIC CORPORATION publishes and distributes children's books, classroom
and professional magazines, and other educational materials including video
and software in the United States. It also markets similar products abroad. It
sells its products in elementary and secondary schools primarily through book
clubs, book fairs, and library sales. In the mid-1990's Scholastic introduced
several core-curriculum products, including reading, science, mathematics, and
preschool programs. Scholastic widely distributes its Credo and Editorial
Platform, which guides much of its editorial policy. This policy stresses the
values of citizenship, democracy, and freedom from prejudice. Many of the
company's publications are
explicitly multicultural. Its CD/ROM literacy program WiggleWorks and its pre-
school and kindergarten instructional program Scholastic Early Childhood Work-
shop are offered in bilingual English/Spanish versions. Its Action classroom
magazine is targeted to at-risk students. In 1995 the company introduced Lit-
eracy Place, a core-curriculum reading program to help children develop their
reading and learning skills. Literacy Place also has a Spanish program, called
Scholastic Solares for bilingual students. As of July 31, 1998, Scholastic
Corporation represented .014% of the DSIP.
 
  SPARTAN MOTORS, INC. designs, manufactures, and markets custom heavy-duty
chassis used for motor homes, fire trucks, school buses, transit buses, and
specialty vehicles. Spartan is aggressively innovative in its product design.
In recent years it has brought to market a motor home chassis with a rear-
mounted diesel engine which offered substantial cost savings over previous
models. In 1997 the company introduced an independent front suspension system
for its motor home chassis which allows better wheel control and handling.
Spartan has also made several notable innovations in fire engine design, in-
cluding an enclosed cab with safety advantages and a cab that, because it
lacks the traditional partition between the front and back seats, facilitates
communications among the firemen. In 1994 the firm initiated research and de-
velopment of a low-floor bus chassis that would meet the standards of the
American with Disabilities Act and eliminate the need for mechanically powered
wheelchair lifts. In 1996 Spartan introduced the first rear exit door school
bus chassis. In 1995 the company introduced a school bus with a rear-engine
design that improves the sight line of the driver and features a quieter motor
that facilitates communication with the passengers. All these features address
safety issues for school bus drivers. In 1994 the company introduced a 24-hour
emergency road service program for its recreational vehicle customers. In 1995
the company increased its quality control staff and introduced new work rules
that allow quality control personnel to halt production if a quality issue

arises. As of July 31, 1998, Spartan Motors, Inc. represented .001% of the

  HUFFY CORPORATION manufactures and markets leisure products, including bi-
cycles, garden tools, basketball equipment, and juvenile products. It also
provides inventory, assembly, repair, and merchandising services for retail
stores. Huffy conducts its business through six companies: Huffy Sports, Huffy
Service First, Washington Inventory Service, Gerry Baby Products, Huffy Bicyc-
les, and True Temper Hardware. The company markets primarily in the U.S. Since
the mid-1980s, the company has instituted a variety of Deming-style quality-
control initiatives. Quality control has become the responsibility of teams of
employees. To assure that quality standards are met, employees have the right
to shut down the manufacturing line at the company's Celina, Ohio, plant. In
1995 the company introduced the country's first 100% postconsumer recycled
aluminum bicycle. Three Huffy Metaloid bicycle models were introduced for the
juvenile market. Huffy Sports Company also introduced a basketball backboard
made out of 100% postconsumer materials. As of July 31, 1998, Huffy Corpora-
tion represented .003% of the DSIP.
 
  LAWSON PRODUCTS, INC. distributes maintenance, repair, and replacement parts
and products, including fasteners and fitting parts such as screws, nuts, and
rivets; industrial supplies, such as hoses, lubricants, cleansers, files, and
drills; and automotive and equipment maintenance parts, such as wiring, con-
nectors, exhaust, and other automotive parts. The firm has implemented a for-
mal "quality of service" program throughout its organization. It trains agents
to provide customer education on the proper use and maintenance of its prod-
ucts. It does not manufacture the products it distributes, but maintains
strict quality control standards for its suppliers. The company's commitment
to quality control leads it to purchase primarily from domestic suppliers.
This practice allowed it to avoid an influx of counterfeit fasteners from the
Far East in the late 1980s. The company competes primarily on service, rather
than on price. The company reports that it ships virtually all products within
24-hours of receiving the orders. In January 1996, the company was awarded the
ISO 9002 certification for its Des Plaines facility in Illinois. The ISO is an
international standards organization. The 9000 certification series addresses
quality management issues. As of July 31, 1998, Lawson Products, Inc. repre-
sented .004% of the DSIP.

/1/ The performance information in this chart represents past performance. The
investment return and principal value of an investment will fluctuate so that
an investor's shares, when redeemed, may be worth more or less than their
original cost. The S&P 500 is an unmanaged index used to portray the pattern
of common stock movement based on the average performance of 500 widely held
common stocks. The index does not pay expenses.
/2/ The Domini Institutional Social Equity Fund, which commenced operations on
May 30, 1996 invests all of its assets in the Domini Social Index Portfolio
which has the same investment objections as the Fund. Performance prior to
commencement of operations is the performance of the Domini Social Index Port-
folio adjusted for expenses of the Fund.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES. Domini Social Index Port-
folio (the "Index Portfolio") is registered under the Investment Company Act
of 1940 (the "Act") as a no-load, diversified, open-end management investment
company which was organized as a trust under the laws of the State of New York
on June 7, 1989. The Index Portfolio intends to correlate its investment port-
folio as closely as is practicable with the Domini 400 Social Index (the "In-
dex"), which is a common stock index developed and maintained by Kinder,
Lydenberg, Domini & Co., Inc. ("KLD"). The Declaration of Trust permits the
Trustees to issue an unlimited number of beneficial interests in the Index
Portfolio. The Index Portfolio commenced operations upon effectiveness on Au-
gust 10, 1990 and began investment operations on June 3, 1991.
 
  The preparation of financial statements in conformity with generally ac-
cepted accounting principles requires management to make estimates and assump-
tions that affect the reported amounts of assets and liabilities and disclo-
sure of contingent assets and liabilities at the date of the financial state-
ments and the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates. The following is a
summary of the Index Portfolio's significant accounting policies.
 
  (A) VALUATION OF INVESTMENTS: The Index Portfolio values securities at the
last reported sale price, or at the last reported bid price if no sales are
reported.
 
  (B) DIVIDEND INCOME: Dividend income is reported on the ex-dividend date.
 
  (C) FEDERAL TAXES: The Index Portfolio will be treated as a partnership for
U.S. federal income tax purposes and is therefore not subject to U.S. federal
income tax. As such, each investor in the Index Portfolio will be taxed on its
share of the Index Portfolio's ordinary income and capital gains. It is in-
tended that the Portfolio will be managed in such a way that an investor will
be able to satisfy the requirements of the Internal Revenue Code applicable to
regulated investment companies.
 
  (D) OTHER: Investment transactions are accounted for on the trade date.
Gains and losses are determined on the basis of identified cost.
 
2. TRANSACTIONS WITH AFFILIATES.
 
  (A) MANAGER. Domini Social Investments LLC ("DSIL" or the "Manager") is reg-
istered as an investment adviser under the Investment Advisers Act of 1940.
The services provided by the Manager consist of investment supervisory servic-
es, overall operational support and administrative services. The administra-
tive services include the provision of general office facilities and supervis-
ing the overall administration of the Index Portfolio. For its services under
the Management Agreement, the Manager receives from the Index Portfolio a fee
accrued daily and paid monthly at an annual rate equal to 0.20% of the Index
Portfolio's average daily net assets, subject to reduction to the extent nec-
essary to keep the aggregate annual operating expenses of the Index Portfolio
(excluding brokerage fees and commissions, interest, taxes and other extraor-
dinary expenses) at no greater than 0.20% of the average daily net assets of
the Index Portfolio through October 22, 1998 (the contract anniversary date).

  (B) SUBMANAGER. Mellon Equity provides investment submanagement services to
the Index Portfolio on a day-to-day basis pursuant to a Submanagement Agree-
ment with DSIL. Mellon Equity does not determine the composition of the Domini
Social Index. Under the Submanagement Agreement, DSIL pays Mellon Equity an
investment submanagement fee equal, on an annual basis, to 0.10% of the aver-
age daily net assets of the Portfolio.
 
  (C) PRIOR ADVISORY, MANAGEMENT, SPONSORSHIP AND ADMINISTRATIVE
AGREEMENTS. Prior to October 22, 1997, pursuant to an investment advisory
agreement, KLD served as investment adviser to the Index Portfolio and fur-

                         Independent Auditors' Report
 
The Board of Trustees and Investors
Domini Social Index Portfolio:
 
  We have audited the accompanying statement of assets and liabilities, in-
cluding the portfolio of investments, of Domini Social Index Portfolio (the
"Portfolio") as of July 31, 1998, and the related statement of operations for
the year then ended, and the statements of changes in net assets for each of
the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended. These financial state-
ments and financial highlights are the responsibility of the Portfolio's man-
agement. Our responsibility is to express an opinion on these financial state-
ments and financial highlights based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of July 31, 1998 by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reason-
able basis for our opinion.
 
  In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Domini Social Index Portfolio as of July 31, 1998, the results of its opera-
tions for the year then ended, changes in its net assets for each of the years
in the two-year period then ended, and financial highlights for each of the
years in the five-year period then ended, in conformity with generally ac-
cepted accounting principles.

DOMINI INSTITUTIONAL SOCIAL EQUITY FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1998
- -------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES. Domini Institutional Social Equity Fund
(the "Fund") is a series of Domini Institutional Trust and is registered as an
open-end management investment company under the Investment Company Act of
1940. The Fund invests substantially all of its assets in the Domini Social
Index Portfolio (the "Portfolio"), an open-end, diversified management invest-
ment company having the same investment objective as the Fund. The value of
such investment reflects the Fund's proportionate interest in the net assets
of the Portfolio (approximately 18.1% at July 31, 1998). The financial state-
ments of the Portfolio are included elsewhere in this report and should be
read in conjunction with the Fund's financial statements. The Fund commenced
operations on May 30, 1996.
 
  The preparation of financial statements in conformity with generally ac-
cepted accounting principles requires management to make estimates and assump-
tions that affect the reported amounts of assets and liabilities and disclo-
sure of contingent assets and liabilities at the date of the financial state-
ments and the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates. The following is a
summary of the Fund's significant accounting policies.
 
  A. VALUATION OF INVESTMENTS. Valuation of securities by the Portfolio is
discussed in Note 1 of the Portfolio's Notes to Financial Statements which are
included elsewhere in this report.
 
  B. INVESTMENT INCOME AND DIVIDENDS TO SHAREHOLDERS. The Fund earns income
daily, net of Portfolio expenses, on its investments in the Portfolio. Divi-
dends to shareholders are declared and paid quarterly from net investment in-
come. Distributions to shareholders of net realized capital gains, if any, are
made annually.
 
  C. FEDERAL TAXES. The Fund's policy is to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies and to dis-
tribute substantially all of its taxable income, including net realized gains,
if any, within the prescribed time periods. Accordingly, no provision for fed-
eral income or excise tax is necessary.
 
  D. OTHER. All net investment income and realized and unrealized gains and
losses of the Portfolio are allocated daily pro rata among the Fund and the
other investors in the Portfolio.
 
2. TRANSACTIONS WITH AFFILIATES.
 
  A. MANAGER. The Index Portfolio has retained Domini Social Investments LLC
("DSIL" or the Manager) to serve as investment manager and administrator. The
services provided by DSIL consist of investment supervisory services, overall
operational support and administrative services, including the provision of
general office facilities and supervising the overall administration of the
Portfolio. For its services under the Management Agreement, the Manager re-
ceives from the Portfolio a fee accrued daily and paid monthly at an annual
rate equal to 0.20% of the Index Portfolio's average daily net assets, subject
to a reduction to the extent necessary to keep the aggregate annual operating
expenses of the Index Portfolio (excluding brokerage fees and commissions, in-
terest, taxes, and other extraordinary expenses) at no greater than 0.20% of
the average daily net assets of the Index Portfolio through October 22, 1998.
 
  B. SUBMANAGER. Mellon Equity provides investment submanagement services to
the Portfolio on a day-to-day basis pursuant to a Submanagement Agreement with
DSIL. Mellon Equity does not

determine the composition of the Domini Social Index. Under the Submanagement
Agreement, DSIL pays Mellon Equity an investment submanagement fee equal on an
annual basis to 0.10% of the average daily net assets of the Portfolio.
 
  C. SPONSOR. Pursuant to a Sponsorship Agreement, DSIL provides the Fund with
the administrative personnel and services necessary to operate the Fund. In
addition to general administrative services and facilities for the Fund simi-
lar to those provided by DSIL to the Index Portfolio under the Management
Agreement, DSIL answers questions from the general public and the media re-
garding the composition of the Domini Social Index and the securities holdings
of the Index Portfolio. For these services and facilities, DSIL receives fees
computed and paid monthly from the Fund at an annual rate equal to 0.25% of

The Board of Trustees and Shareholders
Domini Institutional Social Equity Fund:
 
  We have audited the accompanying statement of assets and liabilities of Do-
mini Institutional Social Equity Fund as of July 31, 1998, and the related
statement of operations for the year then ended, and the statements of changes
in net assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years in the two-year period then ended
and for the period from May 30, 1996 (commencement of operations) to July 31,
1996. These financial statements and financial highlights are the responsibil-
ity of the Fund management. Our responsibility is to express an opinion on
these financial statements and financial highlights based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. An audit also includes assessing the ac-
counting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.
 
  In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Domini Institutional Social Equity Fund as of July 31, 1998, the results of
its operations for the year then ended, changes in its net assets for each of
the years in the two-year period then ended, and financial highlights for each
of the years in the two-year period then ended and for the period from May 30,
1996 (commencement of operations) to July 31, 1996, in conformity with gener-
ally accepted accounting principles.
