THE PARNASSUS INCOME FUND
PROSPECTUS-MAY 1, 1996
    

The  Parnassus  Income Fund (the "Fund") is a "no load,"  diversified,  open-end
series  management  investment  company  managed by Parnassus  Investments  (the
"Adviser").  The  Adviser  chooses  the Fund's  investments  for all  portfolios
according to social  standards  described in this  Prospectus.  In general,  the
Adviser will choose investments that it believes will have a
positive social impact.
   

The Fund has three portfolios. The Balanced Portfolio invests in both stocks and
bonds and its investment objective is both current income and capital gains. The
Fixed-Income  Portfolio  invests  primarily  in  bonds  and  other  fixed-income
investments and its investment  objective is current income and  preservation of
capital. The California Tax-Exempt Portfolio (for California residents only) has
as its  investment  objective a high level of current income exempt from federal
and  California   personal  income  taxes  consistent  with  prudent  investment
management.  This Prospectus  provides you with the basic information you should
know  before  investing  in the Fund.  You should read it and keep it for future
reference.  A Statement of Additional  Information  dated May 1, 1996 containing
additional  information  about the Fund has been filed with the  Securities  and
Exchange  Commission and is  incorporated by reference in this Prospectus in its
entirety.  You may  obtain a copy of the  Statement  of  Additional  Information
without charge by calling the Fund at (800) 999-3505.

FUND EXPENSES
The following table  illustrates all expenses and fees that a shareholder of the
Fund will incur.

Management  Fees  (after  fee  waiver)        0%      0%             0%

Otherexpenses(after expense  reimbursement)  0.72%     0.90%        0.50%
Total Fund Operating Expense                 0.72%*    0.90%*       0.50%*
    

The purpose of this table is to assist the investor in understanding the various
costs  and  expenses  that a  shareholder  in the Fund  will  bear  directly  or
indirectly. The following example illustrates the expenses that you would pay on
a $1000  investment  over various time periods  assuming (1) a 5% annual rate of
return and (2) redemption at the end of each time period.  As noted in the table
above, the Fund charges no redemption fees of any kind.
   

                                  One Year   Three Year  Five Years  Ten Years
Balanced Portfolio                  $7          $23          $40      $89
Fixed-income Portfolio               9           29           50       111
California Tax-Exempt Portfolio      5           16           28       63

The  expenses  shown above are  cumulative--#not  ones you pay every  year.  For
example,  the $89 figure for ten years with the  Balanced  Portfolio  is not the
annual expense,  but the total cumulative expenses a shareholder would have paid
for the  entire  ten-year  period.  This  example  should  not be  considered  a
representation of past or future expenses or performance. Actual expenses may be
greater  or less  than  those  shown.  From  time to time,  the Fund may  direct
brokerage commissions to firms that may pay certain expenses of the Fund subject
to "best  execution."  This is done only when brokerage costs are reasonable and
the Fund  determines  that the  reduction of expenses is in the best interest of
the  shareholders.  See  page B-7 of the SAI for more  information.  Since  this
happens on an  irregular  basis,  the  effect on the  expense  ratios  cannot be
calculated with any degree of certainty.  * The Fund will  compensate  Parnassus
Investments for its services as Transfer Agent and Accounting  Agent in the form
of fixed fees,  which are not based upon a percentage  of the average net assets
of the Fund.  The Adviser has agreed to reduce its  management fee to the extent
necessary  to limit  total  operating  expenses  to 1.25% of net  assets for the
Balanced  Portfolio and 1.00% of net assets for the  Fixed-Income and California
Tax-Exempt  Portfolios.  For 1995,  Parnassus  Investments  reduced its fees and
reimbursed  expenses  so that the  expense  ratios  were even  lower  than these
limits.  Had there been no expense  reimbursement  or fee waiver,  total expense
ratios for the Balanced, Fixed-Income and California Tax-Exempt Portfolios would
have been 1.54%, 1.63% and 1.19% respectively.

seven-month  period  ended  December 31,  1992;  therefore,  the actual ratio of
expenses to average net assets for each portfolio was 0%. Note: This information
is taken from audited  financial  statements  that were  published in the Fund's
annual reports and was audited by Deloitte & Touche llp.
    


THE LEGEND OF MT. PARNASSUS
Parnassus is a mountain in central  Greece whose twin peaks rise more than 8,000
feet above sea level. A dense forest covers the slopes of Mt. Parnassus, but the
summit is rocky and, most of the time,  covered with snow.  The mountain plays a
prominent role in Greek mythology because on its southern slope, overlooking the
Gulf of Corinth, lies Delphi, site of the famous oracle.
  Originally, the oracle belonged to Gaia, the earth goddess.  Later,  Mother 
Earth was worshipped  under the name  Delphyne and she  controlled  the oracle 
along with her serpent-son, Python, and her  priestess-daughters who controlled
the rites.  Eventually,  theGreek god, Apollo,  took over the site, doing away
with Python, but keeping the priestesses. 
  The most "Greek" of the gods, Apollo represented enlightenment and
civilization and presided over the establishment of cities.  Identified with the
development  of Greek codes of law,  Apollo was also the god of light,  a master
musician and a skilled archer.  Legend has it that Python,  an enormous  serpent
raised  in the  caves of Mt.  Parnassus,  controlled  the site of  Delphi.  When


                                       4
<PAGE>

Apollo,  representing  civilization,  challenged Python,  representing  anarchy,
there was a heroic struggle, but the god finally killed the dragon by shooting a
hundred  arrows into its body. 
 There were many oracles in ancient  Greece,  but only the one at Delphi 
achieved  a record of  reliability.  Apollo's  temple at Delphi soon became an
enormous  storehouse of treasures that were gifts of those who had consulted 
the oracle.  The oracle  communicated  through the voice of a priestess who
spoke while in a trance.  The priests of Delphi,  who  interpreted
the sayings of the priestess, obtained a great deal of knowledge and information
from  talking to the people who came from all over the Greek world to consult at
the shrine of Apollo. Quite often, the oracle went against the prevailing wisdom
of the time and frequently, the proud were humbled and the lowly were justified.

INVESTMENT OBJECTIVE AND POLICIES
SOCIAL POLICY
The Adviser will look for certain  social  policies in the companies in which it
invests.  These social  policies  are: (1) treating  employees  fairly (2) sound
environmental protection policies (3) a good equal employment opportunity policy
(4) quality products and services (5) sensitivity to the communities  where they
operate  and (6)  ethical  business  practices.  Obviously,  no company  will be
perfect  in all  categories,  but the  Adviser  will make  value  judgements  in
deciding which companies best meet the criteria.  The Adviser will also consider
social  factors  other  than  these  six  (as  discussed  under  the  investment
objectives of each of the three  portfolios).
 Although the Fund will  emphasize positive  reasons for investing in a company,
our  operating  policies call for excluding companies that manufacture alcohol
or tobacco products or are involved with  gambling.  The Fund also  screens out
weapons  contractors  and those that generate  electricity  from nuclear power. 
 The social criteria of the Parnassus Income Fund limit the  availability of 
investment  opportunities.  However,  the Trustees and the Adviser believe that
there are sufficient investments available that can meet the Fund's social 
criteria and still provide a competitive rate of return.

BALANCED PORTFOLIO
The primary  objective of the Balanced  Portfolio is current  income and capital
preservation.  Capital appreciation is a secondary objective.  The Fund will try
to  achieve  this   objective  by  investing  in  a  diversified   portfolio  of
fixed-income  and equity  securities.  There is no  predetermined  allocation of
assets  for the  Balanced  Portfolio.  The  Adviser  will  determine  the mix of
investments  depending  upon  its  view  of  the  economic  outlook  and  market
conditions. This portfolio will, however, maintain at least 25% of its assets in
fixed-income  securities at all times.
 The Balanced Portfolio may invest in both common and preferred  stocks as well
as  securities  that are  convertible  into these  instruments.  A common stock
issue selected for this portfolio,  however,


                                       5
<PAGE>

must pay a dividend at least equal to that paid by the average  stock in the S&P
500.  Issuers of equity  securities must meet the social criteria stated in this
prospectus.  The  Balanced  Portfolio  will  have  the  same  criteria  for  its
fixed-income  investments as the Fixed-income  Portfolio.  For details,  see the
description of the Fixed-income Portfolio below. The Balanced Portfolio may also
invest up to 10% of its assets in community development loan funds such as those
that provide  financing for small business and low and moderate  income housing.
The Fund will not make loans to a project  itself,  but rather will invest money
in an intermediary community loan fund. With projects having a strong,  positive
social  impact,  this portfolio may lend money at below market  interest  rates.
Generally speaking,  there will be no secondary market for these loans and thus,
there will be no  liquidity  for these  investments.  Although the Fund may make
concessions  on interest  rate and  liquidity,  no  concessions  will be made on
standards of  creditworthiness.  In general,  the Fund will work with  community
organizations that have had a successful record in making these kinds of loans.

RISK FACTORS
As with all investments,  there are a number of risk factors associated with the
Balanced Portfolio. The equity portion of the Balanced Portfolio poses a risk in
that an individual  enterprise may fall on hard times and operate with little or
no  profits;  this would  depress  the price of its stock.  There are also risks
associated  with the economic  cycle (e.g. a recession)  as well as market risks
that might  sharply  reduce the  valuation of all stocks or stocks in a specific
industry.  Since the  Balanced  Portfolio  will invest only in stocks that pay a
dividend,  the equity portion of the portfolio will be invested in larger,  more
mature companies.  These companies tend to be safer and less volatile than those
companies that don't pay a dividend.  With preferred  stock and  higher-yielding
common stocks such as utilities,  a major risk will be increased  interest rates
that will decrease the market value of the securities in question.  For a fuller
description  of  interest  rate  risk,  see  the  Risk  Factors   section  under
Fixed-income  Portfolio.  The  discussion  of risk  factors in that section also
applies to the fixed- income portion of the Balanced  Portfolio.  There are also
special risks  involved with community  development  loans which may comprise as
much as 10% of this  portfolio.  These loans do not have liquidity and community
loan  funds  don't  have  the  same  kind of  financial  resources  as do  large
commercial  enterprises.  Moreover,  there is no publicly available track record
for  community  loan funds so it is hard to assess the history of these kinds of
loans. In fact, one of the social  objectives of the Parnassus Income Fund is to
establish a publicly available track record for community development loans.

FIXED-INCOME PORTFOLIO
The  investment  objective  of the  Fixed-income  Portfolio  is a high  level of
current income consistent with safety and capital preservation. The Adviser will
try to achieve this  objective by investing in a diversified  portfolio of bonds
and other fixed-income  instruments that are rated investment grade. "Investment
grade" means receiving a rating within the four highest categories as determined
by  a   nationally-recognized   rating  service  such  as  Standard  and  Poor's
Corporation

                                       6
<PAGE>

or Moody's Investors Service. Securities in the lowest of these four
categories  are  considered  investment  grade,  but they  may have  speculative
elements  about them. The  Fixed-Income  Portfolio will have at least 65% of its
net assets in securities rated "A" or better.  See the Appendix in the Statement
of Additional Information for a description of bond ratings.  Obligations issued
or guaranteed by the United States Government, its agencies or instrumentalities
need  not  have  a  rating.  The  fixed-income   securities  may  be  long-term,
intermediate-term or short-term or any combination thereof,  depending on market
conditions.  They may also have floating or variable interest rates.  Securities
in this Portfolio may include preferred stock,  convertible  preferred stock and
convertible  bonds.  The  Fixed-income  Portfolio will invest only in investment
grade securities. We will not invest in "high-yield" or "junk" bonds. Because of
this  emphasis  on  quality  and  safety,  the  yield  may  not be as high as it
otherwise might be. One of the social  objectives of this portfolio is long-term
support for housing. In this regard, the Fund expects that a substantial portion
of the  Fixed-income  Portfolio  will be invested in  obligations of the Federal
Home Loan Mortgage  Corporation  (FHLMC or "Freddie Mac"),  the Federal National
Mortgage Association (FNMA or "Fannie Mae") and the Government National Mortgage
Association  (GNMA or "Ginnie  Mae").  Other  fixed-income  securities  that the
Adviser may choose from that have a positive  social impact include  obligations
of the Student Loan  Marketing  Association  (higher  education) and the Federal
Farm Credit System (family  farms).  This Portfolio may also invest up to 10% of
its assets in community  development loan funds. See the section on the Balanced
Portfolio for details.

RISK FACTORS
The Adviser  anticipates  that the  Fixed-income  Portfolio's  average  weighted
maturity  will be  between  5 and 20  years.  Because  of this  relatively  long
maturity,  the value of this  portfolio  will vary  inversely  with  changes  in
interest  rates. As interest rates go up, the net asset value (NAV) will go down
and as  interest  rates  drop,  the  NAV  of  this  Portfolio  will  go up.  The
Fixed-income  Portfolio is intended for  investors  who can accept the fact that
there  will be  principal  fluctuations.  The NAV of the  Portfolio  may also be
affected  by things  other than  interest  rates such as credit risk and general
market factors.


CALIFORNIA TAX-EXEMPT PORTFOLIO
The investment  objective of the California  Tax-Exempt  Portfolio is to provide
high current income exempt from both federal and California  personal income tax
while  choosing a portfolio that will have a positive  social and  environmental
impact.  The Adviser will pursue this  objective  by investing in a  diversified
portfolio of tax-exempt,  investment grade securities issued by California state
and local  governments  and by other public  authorities.  This Portfolio is for
California  residents  only.  David  Pogran  is the  portfolio  manager  for the
California Tax-Exempt Portfolio. 
The two principal  classifications of municipal bonds are "general obligation"
and "revenue" bonds. General obligation bonds are backed by the  taxing  power 


                                       7
<PAGE>

of the  issuer and  considered  the safest  type of municipal bond.  Revenue
bonds are backed by the revenue from a specific project and may be backed by the
credit and security of a private user.  Investments  in revenue  bonds have more
potential  risk.  While  interest on private  activity revenue bonds may be tax-
exempt, it may be treated as a tax preference item for taxpayers  subject to the
alternative  minimum tax. The  California  Tax-Exempt Portfolio will minimize
its investment in such bonds and no more than 20% of the Portfolio's  assets 
will be  invested in bonds whose  income is treated as a tax preference  item
under the federal  alternative  minimum tax. The  Portfolio may also  purchase 
a right to sell a security held by the Fund back to the issuer of the  security 
or another  party at an agreed  upon  price at any time  during a stated  period
or on a certain  date.  These  rights are  referred to as "demand features" or 
"puts." The Portfolio  may also purchase  floating or variable rate obligations 
(including  participations)  as well as variable  rate demand notes (VRDNs) 
which  feature  interest  rates  that  float  with an index and a "put" feature.
 For  temporary  purposes,  the  Portfolio  may invest up to 10% of its assets 
in no-load,  open-end  investment  companies  which invest in  tax-exempt
securities  with  maturities  of less than one year ("tax  exempt  money  market
funds")  but the  Portfolio  will put no more than 5% of its assets into any one
fund.  Normally,  the Portfolio will have all its assets  invested in tax-exempt
securities,  but may  temporarily  invest in  short-term  taxable  money  market
instruments.  Temporary  investments  will be limited to  obligations  issued or
guaranteed by the United States Government,  its agencies or  instrumentalities,
prime   commercial   paper  or   deposits   with   federally-insured   financial
institutions. 
 The California  Tax-Exempt Portfolio will contain only investment
grade securities, i.e. those that have been rated at the time of purchase in one
of the four highest  categories  by Moody's,  Standard & Poor's  Corporation  or
Fitch  Investors  Service,  or if  unrated,  being  similar in  quality,  in the
Adviser's opinion, to the top four categories.  These are considered "investment
grade"  securities  although  bonds in the fourth highest  category  ("Baa") are
regarded as having an adequate capacity to pay principal and interest,  but with
greater  vulnerability  to  adverse  economic  conditions;  they  also have some
speculative  characteristics.  (An  Appendix  to  the  Statement  of  Additional
Information contains a description of the ratings of Moody's, Fitch and Standard
& Poor's.)  The  Portfolio  will not invest more than 20% of its total assets in
securities rated in the fourth highest category.  If the rating on an issue held
by the Portfolio falls below investment  grade after purchase,  the Adviser will
consider such an event in its evaluation of a specific security, but it will not
necessarily  result in an automatic sale of that security.  The Portfolio  does,
however, have an operating policy that no more than 5% of its assets may consist
of securities  which were rated  investment  grade at the time of purchase,  but
subsequently  drop below  investment  grade.  Because the California  Tax-Exempt
Portfolio will emphasize  safety and avoid junk bonds and other securities below
investment  grade,  the  yield  may  not be as high as it  otherwise  might  be.
Examples of activities which the Trustees have determined have a positive social
and environmental  impact include financing for schools,  libraries,  hospitals,
mass transit,  low and moderate income housing,  pollution  control  facilities,
renewable energy resources,  energy conservation projects,  park development and
open  space  acquisition.  The  Portfolio  will not  finance  activities  with a


                                       8
<PAGE>

negative  social or  environmental  impact as determined by the Trustees and the
Adviser. 
 Examples of activities with a negative social or environmental  impact
include generating  electricity from nuclear power,  constructing  freeways when
mass transit is more  appropriate and building  large-scale  dams or other water
projects that encourage  waste. For all activities not listed above, the Adviser
will make a  determination  on a  case-by-case  basis as to  whether  or not the
activity  in  question  has a positive  social and  environmental  impact.  
 Some municipal  securities (usually ndustrial development  bonds)are  issued to
finance  privately-operated  sports facilities,  convention  centers,  airports,
parking structures,  factories or commercial developments.  In these situations,
the Adviser will make decisions on a  case-by-case  basis as to the social value
of the project in question. For example, the Adviser would probably refrain from
investing in securities that financed a fast-food operation,  but probably would
invest in an issue used to construct a plant that provided  substantial benefits
to the local community and had no negative  environmental  consequences.  In the
case of a project  benefiting a specific  company,  the Portfolio will apply the
social criteria listed under the "Social Policy" heading in this Prospectus.  In
the case of a sports  facility,  it might have  positive  benefits such as jobs,
community pride, economic development and family activities.  On the other hand,
a new sports facility might have negative environmental  consequences or put too
much  demand  on  community  financial  resources  for the  benefit  of a sports
franchise  owner to the detriment of more  important  community  needs.  Another
important  consideration  in a sports  stadium  might be whether  it  encouraged
public  transit  or caused  more  traffic  jams.  In all cases  such as a sports
facility  where the  Trustees  have not  determined  whether an  activity  has a
positive or negative  social/environmental  impact, the Adviser will balance all
the relevant  factors and make a  determination  if a given  security  meets the
Fund's social criteria.  As a fundamental policy, with respect to 75% of its net
assets, the California  Tax-Exempt Portfolio will not purchase a security if, as
a  result  of the  investment,  more  than  5% of  its  assets  would  be in the
securities of any single issuer. (For this purpose, each political  subdivision,
agency or  instrumentality  and each multi-state  agency which issues industrial
development bonds on behalf of a private entity,  will be regarded as a separate
issuer  for  determining  the  diversification  of  the  California   Tax-Exempt
Portfolio).  Under normal  circumstances,  the California  Tax-Exempt  Portfolio
intends to invest 100% of its assets in California municipal  obligations.  As a
matter of fundamental  investment policy, the Portfolio will invest at least 80%
of its assets in municipal obligations,  the interest on which will be free from
federal income taxation . As an operating  policy,  the Portfolio will invest at
least 65 % of its  assets in  California  municipal  obligations.  Usually,  the
Portfolio  will  substantially  exceed  these  minimum  requirements,   but  the
Portfolio  does intend to invest up to 20% of assets in private  activity  bonds
that may be subject to the federal alternative minimum tax.
   

RISK FACTORS
Since the California  Tax-Exempt  Portfolio will invest  primarily in California
municipal securities, there are special risks involved because of recent changes
in the State  constitution and other laws that raise questions about the ability
of State and municipal  issuers to obtain  sufficient  revenue to pay their bond
obligations.   California  voters  have  approved  an  amendment  to  the  State
constitution  known as  Proposition  13 which  limits ad  valorem  taxes on real
property and restricts the ability of taxing  entities to increase real property
taxes. In addition,  another  constitutional  amendment,  popularly known as the
Gann Initiative, limits increases in revenue appropriations. Federal legislative
proposals have threatened the tax-exempt status or use of municipal  securities.
Recently,  there has also been an  overall  decrease  in tax  revenue  which has
caused the State of California  difficulty  in balancing the budget.  On July 6,
1992,  Moody's  Investors  Service lowered its ratings on  California's  general
obligation  bonds  from  Aa1  to Aa and on  July  15,  1992  Standard  &  Poor's
Corporation  lowered its ratings on such debt from AA to A+. In  announcing  the
downgrade,  each rating organization cited California's continued weak financial
position  and failure to enact a new fiscal year budget when due and  criticized
the State's  widespread use of registered  warrants,  a form of IOU, to meet its
normal and recurring payment  obligations.  In 1994,  continuing budget deficits
resulted in Moody's lowering  California's  credit rating to A1 and Standard and
Poor's lowering the State's rating to A. The Portfolio will invest in securities
with maturities of more than one year and the average maturity of all securities
will  usually be five  years or more.  If the  Adviser  determines  that  market
conditions  warrant a shorter average  maturity,  the Portfolio will be adjusted
accordingly. Since the value of debt obligations typically varies inversely with
changes in interest rates,  the net asset value per share (NAV) of the Portfolio
will also  fluctuate  in this manner.  As interest  rates go up, the NAV will go
down and as interest rates drop,  the NAV will go up. The California  Tax-Exempt
Portfolio is intended for  investors  who can accept the fact that there will be
principal  fluctuations.  (See the  Statement of  Additional  Information  for a
further  discussion  of risk  factors  involved  with  investing  in  California
tax-exempt securities.)
    

OTHER INVESTMENT POLICIES
Under  normal  circumstances,  each  portfolio  of the Fund will have its assets
invested according to its stated investment  objective.  However,  for temporary
defensive  purposes or pending the  investment  of the proceeds of sales of Fund
shares or  portfolio  securities,  all or part of the assets may be  invested in
money market instruments or in repurchase agreements.  In these situations,  the
Fund's portfolios will not be following their investment objectives.  Repurchase
agreements  involve the purchase by the Fund of debt securities and their resale
at an  agreed-upon  price.  In order to minimize  risk, the Fund will enter into
repurchase  agreements  only with recognized  securities  dealers and banks that
present  minimal  credit  risk and, in all  instances,  the  agreements  will be
collateralized  by U.S.  Government  securities  with a value equal to the total
repurchase price.  Repurchase agreements are always for periods of less than one
year and no more than 5% of a  portfolio's  assets may be invested in repurchase
agreements.  The Fund is subject to certain  investment  restrictions  which are
fundamental  policies that cannot be changed without the approval of the holders
of a majority of the Fund's outstanding  voting securities.  An operating policy
of the Fund or a Portfolio  is one that can be changed by the Board of Trustees.
Each  investment  policy  set forth in this  Prospectus  is  fundamental  unless
specifically  described as an operating policy. The investment objective of each
portfolio is a  fundamental  policy as are  restrictions  that provide that each
portfolio  may not (i) with respect to 75% of a portfolio's  net assets,  invest
more than 5% of the  value of its net  assets in  securities  of any one  issuer
(other than  obligations  issued or guaranteed by the United States  Government,
its agencies or  instrumentalities);  (ii) with respect to 75% of a  portfolio's
net assets,  purchase more than 10% of the outstanding  voting  securities or of
any class of securities  of any issuer;  (iii) invest more than 25% of the value
of its total assets in securities of issuers in any one industry; or (iv) borrow
money  except  from banks for  temporary  or  emergency  purposes in amounts not
exceeding  10% of each  portfolio's  total  assets.  (A  portfolio  may not make
additional investments while any borrowings are outstanding.) It is possible for
the Fund to make  limited  investments  in the  securities  of other  investment
companies.  See the Statement of Additional  Information for more details on the
Fund's investment  restrictions.  An operating (although not fundamental) policy
of the Fund is that it should not make an investment if,  thereafter,  more than
15% of a portfolio's net assets would be illiquid. If the Fund finds itself with
more than 15% of a  portfolio's  net assets so invested,  it will take action to
bring the  portfolio's  illiquid  assets below 15%.  Illiquid assets include (i)
those which are  restricted,  i.e.  those which  cannot be freely sold for legal
reasons  (which  the Fund does not  expect to own);  (ii)  fixed  time  deposits
subject to withdrawal  penalties  (other than  overnight time  deposits);  (iii)
repurchase  agreements  having a  maturity  of more than  seven  days;  and (iv)
investments for which market quotations are not readily available.  However, the
15% limit does not include  obligations  which are payable at  principal  amount
plus accrued interest within seven days after purchase.

PERFORMANCE INFORMATION
YIELD OF PORTFOLIOS
From time to time, the Balanced,  the Fixed-income and the California Tax-Exempt
Portfolios may advertise their yields including  current yield,  effective yield
and tax  equivalent  yield.  Current yield refers to the income  generated by an
investment over a specific time period which is then annualized (i.e. the amount
of income  generated  during a seven-day  period is assumed to be generated each
week over a  52-week  period  and is shown as a  percentage  of the  principal).
Effective  yield is calculated in a similar  manner,  but when  annualized,  the
income earned from the investment is assumed to be reinvested.  Effective  yield
differs from current yield because of the  compounding  effect of  reinvestment.
The California Tax-Exempt Portfolio may also advertise its tax equivalent yield.
The Portfolio  calculates  this by taking the tax-exempt  current (or effective)
yield and  dividing it by one minus the maximum  income tax rate for  California
residents (both federal and state) and adding it to that portion (if any) of the
Portfolio's yield that is not tax-exempt.  TOTAL RETURN The Balanced  Portfolio,
the  Fixed-income  Portfolio and the California  Tax- Exempt  Portfolio may each
advertise "total return." Total return refers to the total change in value of an
investment in the portfolio  over a specific time period.  It differs from yield
in that yield  figures  measure  only the income  component  of the  Portfolio's
investments  while total return measures both income and any change in principal
(net asset  value).  For more  information  on how we calculate  yield and total
return,  please see the  Statement of  Additional  Information.  Total return is
historical  in nature and is not intended to indicate  future  performance.  The
Fund will quote total return for the most recent one-year period and the average
annual  total  return  will be  quoted  for the most  recent  five and  ten-year
periods, or for the life of the Portfolio, if shorter.


   
COMPARISON OF FUND PORTFOLIOS

THE ADVISER
Parnassus  Investments  (the  "Adviser"),  One  Market-Steuart  Tower #1600, San
Francisco,  California  94105 acts as investment  adviser to the Fund subject to
the  control  of the  Fund's  Board of  Trustees,  and as such,  supervises  and
arranges the purchase and sale of securities held in the Fund's portfolios.  The
Adviser has been the investment manager of the Parnassus
Fund since 1985 and the Parnassus Income Fund since 1992.
For its  services,  the  Fund,  under  an  Investment  Advisory  Agreement  (the
"Agreement") be-tween the Fund and the Adviser, pays the Adviser a fee, computed
and payable at the end of each month,  at the following  annual  percentages  of
each portfolio's average daily net assets; the Balanced Portfolio,  0.75% of the
first $30  million,  0.70% of the next $70 million and 0.65% of the amount above
$100  million.  For the  Fixed-income  Portfolio and the  California  Tax-Exempt
Portfolio,  the fee is 0.50% of the first $200  million,  0.45% of the next $200
million  and 0.40% of the amount  above $400  million.  In  addition  to the fee
payable to the Adviser,  the Fund is  responsible  for its  operating  expenses,
including:  (i) interest and taxes; (ii) brokerage commissions;  (iii) insurance
premiums;  (iv)  compensation  and  expenses  of its  Trustees  other than those
affiliated  with the  Adviser;  (v)  legal  and  audit  expenses;  (vi) fees and
expenses of the Fund's custodian,  transfer agent and accounting services agent;
(vii) expenses incident to the issuance of its shares, including issuance on the
payment of or  reinvestment of dividends;  (viii) fees and expenses  incident to
the  registration  under  federal  or state  securities  laws of the Fund or its
shares; (ix) expenses of preparing, printing and mailing reports and notices and
proxy material to shareholders of the Fund; (x) all other expenses incidental to
holding  meetings of the Fund's  shareholders;  (xi) dues or  assessments  of or
contributions to the Investment Company  Institute,  the Social Investment Forum
or any  successor;  (xii) such  nonrecurring  expenses  as may arise,  including
litigation  affecting the Fund and the legal obligations which the Fund may have
to  indemnify  its officers and Trustees  with respect  thereto.  In  allocating
brokerage  transactions,  the  investment  advisory  agreement  states  that the
Adviser may consider research provided by brokerage firms or whether those firms
sold  shares  of the  Fund.  See page  B-11 of the SAI for more  information  on
directed brokerage.


HOW TO PURCHASE SHARES
DIRECT PURCHASE OF SHARES
To purchase  shares,  an investor should complete and mail the application  form
along with a check  payable to The  Parnassus  Income Fund. It should be sent to
the Fund at the following address.

The Parnassus Income Fund
One Market-Steuart Tower #1600
San Francisco, California 94105
    

                                       10

An  initial  investment  must be at least  $2,000  except for  certain  employee
benefit plans or tax  qualified  retirement  plans (e.g.  IRA, SEP) which have a
$500 minimum. Subsequent investments for all accounts must be at least $50. With
subsequent  investments,  shareholders  should  write the name and number of the
account  on the  check.  Checks do not need to be  certified,  but are  accepted
subject  to  collection  and must be drawn in United  States  dollars  on United
States banks.  If received  before 1:00 p.m. San Francisco  time, the investment
will be processed at the net asset value  calculated on the same business day it
is received.  If the investment is received after 1:00 p.m. San Francisco  time,
it will be processed the next business day.

OTHER INFORMATION
The Fund also offers  additional  services to investors  including plans for the
systematic  investment  and  withdrawal  of money as well as IRA and SEP  plans.
Information  about these plans is available  from the  Distributor.  The minimum
initial investment in the Fund is $2,000 and the minimum  subsequent  investment
is $50, except for retirement plans, and Parnassus Automatic Investment Accounts
(PAIP) which have a $500 minimum.  The distributor  reserves the right to reject
any order. There is no sales charge for any portfolio of the Fund, but investors
may be  charged a  transaction  or other fee in  connection  with  purchases  or
redemptions of Fund shares on their behalf by an investment adviser, a brokerage
firm  or  other  financial   institution.  
 PURCHASES  VIA  PARNASSUS  AUTOMATIC INVESTMENT  PLAN (PAIP)  After making an
initial investment to open an account($500 minimum), a shareholder may purchase 
additional shares ($50 minimum) via the Parnassus Automatic Investment Plan 
PAIP). On a monthly or quarterly basis, your money will automatically be
transferred from your bank account to your Fund account on the day of your
choice (3rd or 18th day of the month).  You can elect this option by filling out
the PAIP section on the new account form. For further information,  call  the 
und and ask for the  free  brochure  called  "Automatic Investing and Dollar
Cost Averaging.
" NET ASSET VALUE The Fund's net asset value per share is determined at
4:00 p.m.  Eastern time on each day that the New York Stock  Exchange is open 
for trading  ("business  day") and on any other day that there is a  sufficient 
degree of  trading  in  investments  held by the Fund to affect the net asset 
value. The net asset value may not be determined on any day that there are no 
transactions  in shares of the Fund.  The net asset value per share is the value
of the Fund's assets,  less its  liabilities,  divided by the  number of  shares
of the Fund  outstanding.  The value of the  Fund's  portfolio securities will
be the market value of such securities.  However, securities and other assets
for which market quotations are not readily available are valued at
their fair value as  determined  in good faith by the Adviser  under  procedures
established  by and under the  general  supervision  and  responsibility  of the
Fund's  Board of  Trustees.  See the  Statement of  Additional  Information  for
details.

HOW TO REDEEM SHARES
You may sell or redeem  your Fund shares by offering  them for  "repurchase"  or
"redemption"  directly to the Fund. To sell your shares to the Fund (that is, to
redeem  your  shares),  you  must  send  your  instructions  to the  Fund at One
Market-Steuart Tower #1600, San Francisco, California 94105. Your shares will be
redeemed at the net asset  value next  determined  after  receipt by the Fund of
your  instructions  in proper form.  Give your  account  number and indicate the
number of shares you wish to redeem.  All owners of the account must sign unless
the account  application  form states that only one  signature is necessary  for
redemptions.  All redemption checks must be sent to the address of record on the
account.  The Fund must have a  change-of-address  on file for 30 days before we
send redemption or distribution checks to the new address. Otherwise, we require
a signature  guarantee  or the check must be sent to the old  address.  The Fund
usually requires additional  documents when shares are registered in the name of
a corporation,  agent or fiduciary or if you are a surviving joint owner. In the
case of a corporation,  we usually require a corporate  resolution signed by the
secretary.  In the  case of an  agent  or  fiduciary,  we  usually  re-quire  an
authorizing document. In the case of a surviving joint owner, we usually require
a copy of the death certificate.  Contact the Fund by phone at (800) 999-3505 if
you have any questions about requirements for redeeming your shares. If the Fund
has received payment for the shares you wish to redeem and you have provided the
instructions  and any other  documents  needed in  correct  form,  the Fund will
promptly send you a check for the proceeds from the sale.  Ordinarily,  the Fund
must send you a check  within  seven days unless the New York Stock  Exchange is
closed for days other than weekends or holidays. However, payment may be delayed
for any shares  purchased by check for a reasonable  time (not to exceed 15 days
from the date of such  purchase)  necessary  for the Fund to determine  that the
purchase  check  will  be  honored.  Exchange  Privileges.  The  proceeds  of  a
redemption of shares from a portfolio of the Fund can be used to purchase shares
of another  portfolio of the Fund.  The proceeds of a redemption  of shares from
the Fund can also be used to purchase  shares of the Parnassus  Fund,  but if no
sales charge was paid on the shares being  redeemed from the Income Fund,  those
shares  will be  subject  to a sales  charge  when  they are  invested  into the
Parnassus  Fund. If shares are redeemed from the Parnassus  Fund and invested in
the Income Fund,  there will be no  additional  sales charge if those shares are
transferred  back into the Parnassus Fund. There is no limit on the number of or
dollar amount of  exchanges.  The Fund reserves the right to modify or eliminate
this exchange  privilege in the future. The exchange privilege is only available
in states  where the  exchange  may be legally  made.  The exchange of shares is
treated  as a sale and an  exchanging  shareholder  may,  therefore,  realize  a
taxable  gain or  loss.  Telephone  Transfers.  Shareholders  who  elect  to use
telephone transfer  privileges must so indicate on the account application form.
The telephone  transfer  privilege allows a shareholder to effect exchanges from
the Fund into an identically  registered account in another one of the Parnassus
Funds (e.g. The Parnassus Fund). Neither the Fund nor Parnassus Investments will
be liable  for  following  instructions  communicated  by  telephone  reasonably


                                       15
<PAGE>

believed  to be  genuine;  a  loss  to  the  shareholder  may  result  due to an
unauthorized transaction. The Fund and the transfer agent will employ reasonable
procedures to confirm that  instructions  communicated by telephone are genuine.
Procedures  may include one or more of the  following:  recording  all telephone
calls requesting telephone exchanges, verifying authorization and requiring some
form of personal  identification prior to acting upon instructions and sending a
statement  each  time a  telephone  exchange  is made.  The  Fund and  Parnassus
Investments  may be liable  for any losses due to  un-authorized  or  fraudulent
instructions  only if such  reasonable  procedures are not followed.  Of course,
shareholders are not obligated in any way to authorize  telephone  transfers and
may choose to make all exchanges in writing.  The telephone  exchange  privilege
may be modified or  discontinued  by the Fund at any time upon 60 days'  written
notice to shareholders. Redemption of Small Accounts. The Trustees may, in order
to reduce the expenses of the Fund,  redeem all of the shares of any shareholder
whose account is worth less than $1,000 as a result of a redemption  order. This
will be done at the net asset  value  determined  as of the close of business on
the business day  preceding the sending of such notice of  redemption.  The Fund
will give  shareholders  whose shares are being  redeemed 60 days' prior written
notice in which to purchase sufficient shares to avoid such redemption.

                                    


DIVIDENDS AND TAXES
The Balanced  Portfolio normally declares and pays dividends from net investment
income ("income dividends") on a quarterly basis. The Fixed-income Portfolio and
the California Tax Exempt Portfolio normally declare and pay income dividends on
a  monthly  basis.  Dividends  from  long-term  capital  gains  ("capital  gains
dividends") are paid once a year (usually in mid-December) for all portfolios of
the  Fund.  Shareholders  can  have  dividends  paid in  additional  shares  and
reinvested or paid out in cash. If an investor  purchases shares just before the
dividend  date, he or she will be taxed on the  distribution  even though it's a
return of capital.

TAXATION OF THE FUND
By paying out  substantially all its net investment income (among other things),
the  Fund  believes  it  qualifies  as  a  regulated  investment  company  under
Subchapter  M of the  Internal  Revenue  Code.  The Fund  intends to continue to
qualify  and, if so, it will not pay income  taxes on either its net  investment
income or on its capital gains.  Instead,  each  shareholder will be responsible
for his or her own taxes.

TAXATION OF SHAREHOLDERS
For the Balanced  Portfolio and the Fixed-income  Portfolio,  all dividends from
net investment  income together with  distribution  of short-term  capital gains
(collectively,  "income  dividends")  will be  taxable  as  ordinary  income  to
shareholders  even though paid in additional  shares.  Any net long-term capital
gains  ("capital  gains   dividends")  are  taxable  as  such  to  shareholders.
Tax-exempt  shareholders,  of course,  will not be  required to pay taxes on any
amount  paid to them.  (This  includes  IRAs and other  tax-deferred  retirement
accounts.)  Annually,  shareholders  will receive on Form 1099 the dollar amount
and tax status of all  dividends  received.  Under the Interest and Dividend Tax
Compliance Act of 1983, the Fund may be required to impose backup withholding at
a rate of 20% from any  income  dividend  and  capital  gain  distribution  upon
payment  of  redemption   proceeds.   Shareholders   can  eliminate  any  backup
withholding  requirements  by complying with  provisions of that Act relating to
the  furnishing  and  certification  of  taxpayer   identification  numbers  and
reporting of  dividends.  To the extent that income  dividends  are derived from
qualifying dividends paid by domestic corporations whose shares are owned by the
Fund, such dividends, in the hands of the Fund's corporate shareholders, will be
eligible for the 70% dividends  received  deduction.  Individuals do not qualify
for this deduction--#only corporations.

CALIFORNIA TAX-EXEMPT PORTFOLIO
This Portfolio is for California residents only. Dividends derived from interest
on state and local obligations constitute  "exempt-interest"  dividends on which
shareholders  are not  subject to federal  income tax. To the extent that income
dividends are derived from earnings  attributable to California  state and local
obligations,  they will be exempt from federal and  California  personal  income
tax. Such dividends may be subject to California  franchise  taxes and corporate
income  taxes if received  by a  corporation  subject to such  taxes.  Dividends
attributable to interest on certain  private  activity bonds issued after August
7, 1986 must be included in federal  alternative  minimum taxable income for the
purpose of determining  liability (if any) for the alternative minimum tax (AMT)
for individuals and for  corporations for taxable years beginning after December
31,  1986.  Dividends  derived from taxable  interest and any  distributions  of
short-term  capital  gains are  taxable  to  shareholders  as  ordinary  income.
Distributions of long-term capital gains, if any, are taxable to shareholders as
a long-term  capital gain  regardless  of how long their shares of the Portfolio
have been held except  that  losses on certain  shares held less than six months
will be  treated as  long-term  capital  losses to the  extent of the  long-term
capital  gains  dividends  received on such shares.  The  Portfolio  will notify
shareholders  each  January  as to the  federal  and  California  tax  status of
dividends paid during the previous calendar year.

GENERAL INFORMATION
The Fund was organized as a Massachusetts  business trust on August 8,1990.  The
Declaration  of Trust  provides  the  Trustees  will not be liable for errors of
judgement  or mistakes of fact or law, but nothing in the  Declaration  of Trust
protects a Trustee  against any liability to which he or she would  otherwise be
subject  by reason of  willful  misfeasance,  bad  faith,  gross  negligence  or
reckless  disregard of the duties  involved in the conduct of his or her office.
Shareholders  are entitled to one vote for each full share held (and  fractional
votes for  fractional  shares) and may vote in the  election of Trustees  and on
other matters  submitted to meetings of shareholders.  In matters  pertaining to
only one series of the Trust (i.e. one  Portfolio),  only holders of that series
are entitled to vote, so matters that require the approval of outstanding shares
must be  approved  by the  holders of a  majority  of each  series  that will be
affected by the matter.  On issues related to the Fund as a whole,  specifically
including  election  of  Trustees  and  ratification  of  the  Fund's  principal
underwriter and selection of the Fund's independent public accountants,  holders
of all series will vote. It is not contemplated  that regular annual meetings of
shareholders  will be held.  The  Declaration  of Trust provides that the Fund's
shareholders  have the right,  upon the  declaration  in writing or vote of more
than two-thirds of its  outstanding  shares,  to remove a Trustee.  The Trustees
will call a meeting of  shareholders  to vote on the  removal of a Trustee  upon
written request of the record holders of ten percent of its shares. In addition,
ten  shareholders  holding  the lesser of $25,000  worth or one  percent of Fund
shares may advise the  Trustees in writing  that they wish to  communicate  with
other  shareholders for the purpose of requesting a meeting to remove a Trustee.
The Trustees will then, if requested by the applicant,  mail at the  applicants'
expense the applicant's  communication to all other  shareholders.  No amendment
may be made to the  Declaration  of Trust  without the  affirmative  vote of the
holders of more than 50% of our  outstanding  shares,  or upon  liquidation  and
distribution of its assets,  if approved by the vote of the holders of more than
50% of our  outstanding  shares.  If not so  terminated,  the Fund will continue
indefinitely.  Deloitte & Touche llp, 50 Fremont Street, San Francisco, CA 94105
has been selected as the Fund's independent auditors.  Union Bank of California,
475 Sansome Street, San Francisco,  CA 94111, has been selected as the custodian
of the Fund's  assets.  Shareholder  inquiries  should be  directed to the Fund.
Parnassus Investments, One Market-Steuart Tower #1600, San Francisco, California
94105,  is the Fund's  transfer agent and accounting  agent.  As transfer agent,
Parnassus  Investments  receives  a fee of  $2.30  per  account  per  month.  As
accounting  agent,  Parnassus  Investments  receives a fee of $50,000  per year.
Jerome L. Dodson,  the Fund's  President,  is the sole  stockholder of Parnassus
Investments.

Investment Objectives and Policies

         The main  investment  objective of the Fund is to provide  shareholders
with current  income by investing in securities  that have a positive  impact on
society.  The Fund  offers  investors a choice of three  portfolios:  a Balanced
Portfolio, a Fixed-Income  Portfolio and a California Tax-Exempt Portfolio.  The
Fund's Prospectus describes its strategy with respect to the composition of each
portfolio.

Investment Restrictions

         The Fund has adopted the following  restrictions  (in addition to those
indicated in the  Prospectus) as  fundamental  policies which may not be changed
without  the  approval  of  the  holders  of a  "majority"  (as  defined  in the
Investment Company Act of 1940) of the Fund's outstanding  shares. A vote of the
holders of a "majority" (as so defined) of the Fund's outstanding shares means a
vote  of the  holders  of the  lesser  of (i)  67%  of  the  shares  present  or
represented  by proxy at a meeting  at which  more  than 50% of the  outstanding
shares are represented or (ii) more than 50% of the outstanding shares.

The Fund may not:

         (1)With respect to 75% of its total net assets, purchase the securities
of any one issuer other than obligations of the U.S. Government, its agencies or
instrumentalities,  if as a result:  (i) more than 5% of a portfolio's total net
assets (taken at current value) would then be invested in securities of a single
issuer or (ii) a portfolio  would hold more than 10% of any class of  securities
of an issuer (taking all common stock issues as a single class) or more than 10%
of the outstanding voting securities of an issuer.

         (2)Purchase any security if as a result any portfolio would have 25% or
more of its net  assets  (at  current  value)  would  be  invested  in a  single
industry.

         (3)Purchase  securities  on  margin  (but  the  Fund  may  obtain  such
short-term credits as may be necessary for the clearance of transactions).

         (4)Make short sales of securities, purchase on margin or purchase puts,
calls, straddles or spreads.

         (5)Issue  senior  securities,  borrow money or pledge its assets except
that each  portfolio may borrow from a bank for temporary or emergency  purposes
in amounts not  exceeding  10% (taken at the lower of cost or current  value) of
its net assets  (not  including  the amount  borrowed)  and pledge its assets to
secure such borrowings.  The portfolio will not make additional  purchases while
any borrowings are outstanding.



                                       


         B-2


                                       
<PAGE>

         (6)Invest in securities of any issuer if, to the knowledge of the Fund,
any officer or Trustee of the Fund or officer or  director  of the Adviser  owns
more than one-half of 1% of the  outstanding  securities of such issuer and such
officers and Trustees who own more than one-half of 1% own in the aggregate more
than 5% of the outstanding securities of such issuer.

(7)Buy or sell commodities or commodity contracts including futures contracts or
real estate, real estate limited  partnerships or other interests in real estate
although it may purchase and sell  securities of companies  which invest or deal
in real estate.

(8)Act  as  underwriter  except  to the  extent  that  in  connection  with  the
disposition of portfolio securities, it may be deemed to be an underwriter under
certain  federal  securities  laws.  (9)Make  investments  for  the  purpose  of
exercising a controlling influence over the management or policies of a company,
except that the Fund may seek to influence the social  policies of the companies
it invests in.

(10)     Participate on a joint or joint and several basis in any trading
         account in securities.

(11)Purchase any security restricted as to disposition under federal
securities laws.

(12)Invest in securities of other  registered  investment  companies except that
each  portfolio may invest up to 10% of its assets  (taken at current  value) in
money  market  funds,  but no more than 5% of its  assets in any one fund and no
portfolio may own more than 3% of the outstanding voting shares of any one fund.
The Adviser will waive its  management  fee on any portion of the Fund's  assets
that are invested in another registered  investment  company.  This restriction,
however,  does  not  apply  to a  transaction  that  is  a  part  of  a  merger,
consolidation or other acquisition.

(13)Invest in interests in oil, gas or other mineral  exploration or development
programs or in oil, gas or other  mineral  leases  although it may invest in the
common stocks of companies which invest in or sponsor such programs.

(14)Invest  more  than  5% of the  Balanced  Portfolio  or  more  than 5% of the
Fixed-Income   Portfolio  in  foreign  securities.   The  California  Tax-Exempt
Portfolio may not invest in foreign securities or currencies.

(15)Purchase  warrants, if as a result, a Portfolio would then have more than 5%
of its total assets  (taken at current  value)  invested in  warrants.  Included
within that amount,  but not to exceed 2% of the value of a Portfolio's  assets,
may be  warrants  which are not  listed on the New York  Stock  Exchange  or the
American Stock Exchange.

         (16)Make loans except through  repurchase  agreements.  Each portfolio,
though, may invest no more than 5% of its assets in repurchase  agreements.  The
Balanced Portfolio and the Fixed-Income  Portfolio,  however, may lend up to 10%
of  each  Portfolio's  assets  to  community  loan  funds  as  described  in the
Prospectus.  The Fund will not make  loans  directly  to a project  itself,  but
rather will invest in an intermediary community loan fund.

         (17)Invest more than 5% of the assets of any one portfolio in the
securities of unseasoned issuers (i.e. those with less than three
years of continuous operation).

Repurchase Agreements

         The Fund may purchase the  following  securities  subject to repurchase
agreements: certificates of deposit, certain bankers' acceptances and securities
which are direct  obligations of, or that are fully  guaranteed as to principal,
by the United States or any agency or  instrumentality  of the United States.  A
repurchase  transaction  occurs when at the time the Fund  purchases a security,
the  Fund  also  resells  it to the  vendor  (normally  a  commercial  bank or a
broker-dealer) and must deliver the security (and/or securities  substituted for
them under the repurchase agreement) to the vendor on an agreed-upon date in the
future. Such securities,  including any securities so substituted,  are referred
to as the "Resold Securities". The Adviser will consider the creditworthiness of
any vendor of repurchase  agreements and continuously  monitor the collateral so
that it never falls below the resale price. The resale price is in excess of the
purchase price in that it reflects an agreed-upon market interest rate effective
for the period of time during  which the Fund's  money is invested in the Resold
Securities.  The  majority  of  these  transactions  run from day to day and the
delivery  pursuant to the resale typically will occur within one to five days of
the purchase. The Fund's risk is limited to the ability of the vendor to pay the
agreed-upon sum upon the delivery date.

      If there is a default,  the Resold Securities  constitute security for the
repurchase obligation and will be promptly sold by the Fund. However,  there may
be delays and costs in establishing  the Fund's rights to the collateral and the
value of the collateral may decline.  The Fund will bear the risk of loss in the
event that the other party to the transaction defaults on its obligation and the
Fund is  delayed  or  prevented  from  exercising  its right to  dispose  of the
underlying securities,  including the risk of a possible decline in the value of
the  underlying  securities  during the period in which the Fund seeks to assert
its rights.

     Repurchase  agreements can be considered as loans  "collateralized"  by the
Resold  Securities  (such  agreements being defined as "loans" in the 1940 Act.)
The  return  on  such  "collateral"  may be  more or less  than  that  from  the
repurchase  agreement.  The  Resold  Securities  will be marked to market  every
business  day so that the  value of the  "collateral"  is at least  equal to the
value of the loan  including the accrued  interest  earned  thereon.  All Resold
Securities  will be held by the Fund's  custodian  either  directly or through a
securities depository.

     SPECIAL RISK FACTORS AFFECTING CALIFORNIA MUNICIPAL SECURITIES

         Changes  in  California  could  adversely  affect  the  market  values,
marketability  (the ability to sell or buy), or result in a default on municipal
securities issued in the State. The economic  condition of the State affects tax
revenues and could have an adverse effect on municipal obligations. What follows
is a discussion of some of the more important legal and financial  trends.  This
discussion  is  based  on  information  drawn  from  official  prospectuses  and
statements of the State of California.

Limitations on Taxes and Appropriations

         Some  municipal  securities  held in the portfolio may depend wholly or
partially  on property  taxes as a revenue  source for  payment of interest  and
principal.  Article XIIIA,  popularly known as Proposition 13, limits ad valorem
property taxes (property taxes based on the property's value) to 1% of full cash
value of the property and limits  increases in assessments to 2% per year except
in the case of new  construction  or a change in ownership.  However,  if voters
approve a bond  issue,  property  taxes may be raised  above the 1% level to pay
debt service on that bond.

         In 1986,  voters  approved  Proposition  62 which  imposed  limits on a
locality's  raising or levying  general  taxes.  Although major portions of this
initiative  were initially  overturned in court in November 1995, the California
Supreme Court made a ruling supporting Proposition 62.

         Article  XIIIB  (known as the Gann  Initiative),  enacted in 1979 via a
voter  initiative,  subjects  State and  local  governments  to annual  spending
limitations.  These limitations are adjusted annually to reflect changes in cost
of living and  population  and only apply to the  appropriation  of "proceeds of
taxes."  Spendable  funds exempted from these  appropriation  limits include the
proceeds of bond issues and revenue from user fees. Debt service on bonds issued
prior to January 1, 1979 or subsequently  authorized by voters is not subject to
these limitations.

         Article  XIIIB's  appropriation  limitations  did  not  constrain  most
California  governmental  entities  until the mid and late  1980's  when many of
these entities  approached their Article XIIIB spending  limits.  The passage of
Proposition 111 in 1990 allowed for greater increases in appropriation levels.

         In November 1988, voters approved Proposition 98, a combined initiative
constitutional  amendment and statute  guaranteeing minimum State funding for K-
12 school  districts  and  community  college  districts at a level equal to the
greater of (a) the same  percentage of general fund  revenues as the  percentage
appropriated   to  such  districts  in  1986-87  or  (b)  the  amount   actually
appropriated to such districts from the general fund in the previous fiscal year
adjusted for growth in enrollment and changes in cost of living.

         In June 1990,  California voters approved Proposition 111 which allowed
for some  increase in  appropriation  levels,  but provided that one-half of all
revenues  in excess of the  state's  appropriation  limit must be  allocated  to
public schools and community colleges. Since Proposition 98 and 111 allocated

B-5


                                       22
<PAGE>

a minimum funding level to schools,  this could potentially reduce the resources
available  for other State  programs  and put  pressure on issuers of  municipal
obligations.

         Proposition 13, the Gann Initiative, Proposition 98 and Proposition 111
were adopted as measures that qualified for the ballot  pursuant to California's
initiative  process.   Other  initiatives  or  similar  measures  affecting  the
availability of revenue to pay California municipal obligations could be adopted
in the future.
   

State Financial Condition

         State General Fund  revenues are  principally  derived from  California
personal  income tax (44% of total  revenues),  sales tax (35%),  corporate  tax
(12%) and the gross premium tax on insurance  (3%). All of these revenue sources
have been  negatively  affected  during the  recession  that ended in 1993.  The
resulting  revenue  shortfall  has been a key factor in the  recurring  problems
California has experienced balancing its annual budgets.  Growth in expenditures
compounded the revenue shortfall problem.

         As of June 30, 1995, the state's deficit was estimated at $350 million.
The deficit was reduced over the previous twelve months as the economic recovery
that began in 1993 produced higher tax revenues.  The Governor's budget proposal
plans to eliminate the accumulated deficit by June 30, 1996.

         If the  revenue  assumptions  of the current  budget are not met,  more
negotiation on reducing  expenditures or increasing  revenues could be needed to
balance the budget and eliminate the accumulated deficit.

         Since the passage of Proposition 13, property tax revenues  received by
local  governments  have  dropped  by over  50%.  In  response,  the  California
Legislature has provided  substantial  additional revenue for local governments.
Because  of  budgetary  pressure  and  limits on  allocations  of tax  revenues,
California's  state government has been shifting program  responsibilities  from
the state to county  and city  governments.  To date,  most  changes  in program
responsibilities  from the state to local  governments  have been  balanced with
increases  in  funding.  However,  cuts in state  aid that are not  balanced  by
funding  increases could hurt financially  stressed local  government  entities,
particularly   counties.   Certain  California   municipal   securities  may  be
obligations  of  issuers  which  rely in  whole or in part on  California  state
revenues for payment of these obligations. The proportion of the State's general
fund that  will be  distributed  in the  future to  counties,  cities  and their
various entities, is unclear.
    

Revenues of Health Care Institutions

         Certain California  tax-exempt  securities may be obligations which are
payable solely from the revenues of health care  institutions.  Certain measures
taken under federal or California  law to reduce health care costs may adversely
affect revenues of health care institutions and, consequently,  payment on those
municipal obligations.

                                       23
<PAGE>

Revenues Secured by Deeds of Trust

         Some  California  municipal  securities  may be  obligations  which are
secured in whole or in part by a mortgage or deed of trust on real property.  An
example  would be bonds  issued to  finance  low and  moderate  income  housing.
Because of  provisions  of  California  law, the  effective  minimum  period for
foreclosing  on a mortgage  could be in excess of seven  months from the time of
initial  default.  This delay could disrupt the flow of revenue  available to an
issuer for  payment of debt  service if such  defaults  occur with  respect to a
substantial  number of mortgages or deeds of trust.  Other aspects of California
law could further delay  foreclosure  proceedings  in the event of a default and
disrupt payments on municipal obligations.

Assessment Bonds (Mello-Roos Bonds)

         Typically,  these  bonds  are  secured  by land  undeveloped  as of the
issuance.  The  plan is for the  land  to be  developed  using  funds  from  the
issuance.  Declining  real estate values or a drop in real estate sales activity
can result in canceled or delayed development along with increased default risk.
The special  assessments  or taxes  securing  these  bonds are not the  personal
liability of the owner of the property assessed,  so the lien on the property is
the only security for these bonds.  Furthermore,  in the event of delinquency in
payment of assessments or taxes on the  properties  involved,  the issuer is not
required to make payments on the bonds,  except in some instances where there is
a reserve account for bond payments.

Redevelopment Agency Debt

         "Tax Allocation" bonds issued by redevelopment agencies can be affected
by property tax  limitations  because these bonds are secured by the increase in
assessed valuation expected after a redevelopment  project is completed.  Should
the project not be  completed,  perhaps  because of a natural  disaster  like an
earthquake,  there could be no increase in assessed  property  values to pay off
the bonds. Moody's and S&P stopped rating tax allocation bonds after the passage
of Articles XIIIA and XIIIB,  and since have only resumed rating  selected bonds
of this nature.

Seismic Activity

         California is a geologically  active area subject to  earthquakes.  Any
California  municipal  security  could be adversely  affected by a  catastrophic
earthquake.  For  example,  a project  might not be completed or might suffer an
interruption  in  revenue-generating  capacity,  or property  values  might drop
resulting in reduced tax assessments.

         The October  1989 Loma Prieta  earthquake  resulted in an  estimated $2
billion  reduction in personal income statewide and was offset by reconstruction
activity. The Federal Government provided $3.5 billion in earthquake aid and the
State  Legislature  passed a temporary  sales tax  increase  to fund  earthquake
relief. The earthquake did not materially affect the California economy.

                                       24
<PAGE>

     The  January  1994  Northridge  (Los  Angeles)   earthquake  caused  an
estimated $20 billion or more in property damage.  The state's share of the loss
after  federal aid and  insurance is estimated  at $1.9  billion.  Costs will be
covered from the state's general fund and borrowing from the federal government.
The state's ability to pay principal and interest on its bonds was not affected.
Although isolated instances of damage to some bond-financed facilities occurred,
reserves and insurance  should be sufficient to ensure  payment of principal and
interest according to all the major credit rating agencies.  No credit rating on
any bond in the  earthquake  area was changed as a consequence of the Northridge
earthquake.

Orange County Default

         In  December  of  1994,   Orange  County  declared   bankruptcy   after
discovering that its Treasurer had invested in risky derivative securities which
caused enormous losses to the county's investment fund.  Estimates of the losses
approximate  $1.7 billion.  This bankruptcy  disturbed the California  municipal
bond  market and the market  value of  uninsured  Orange  County  bonds  dropped
sharply. Because the portfolio held no uninsured Orange County bonds, it was not
substantially   affected  by  the  Orange  County  bankruptcy.   However,  other
California  municipalities  may  mismanage  their  investment  funds and, in the
future,  they may also suffer losses which might have an effect on the Portfolio
in that the market value of some municipal securities might drop substantially.

the Adviser or the Distributor annual fees of $1500 in addition to reimbursement
for certain out-of-pocket expenses.

*"Interested" Trustee as defined in the 1940 Act.

CONTROL PERSONS

         As of March 31, 1996, no  shareholder  owned more than 5% of the voting
securities  of  the  Balanced  or  Fixed-Income  Portfolios  of  the  Fund.  One
fiduciary,  however, Charles Schwab & Co., did own 6.39% of the voting shares of
the Balanced  Portfolio.  This account,  though,  represented many shareholders.
MIFLA & Co., a trust,  owned 7.22% of the voting  securities  of the  California
Tax-Exempt  Portfolio.  Trustees and Officers of the Parnassus Income Fund owned
less than 1% of the  outstanding  securities of the Balanced  Portfolio,  of the
Fixed-Income Portfolio and of the California Tax-Exempt Portfolio.

PERFORMANCE ADVERTISING

         From time to time,  the Fund may quote the relative  performance of one
or more of its Portfolios in sales literature or  advertisements  in newspapers,
magazines or other publications. The source for these quotations will be

B-9


                                       26
<PAGE>

Lipper  Analytical  Services,   Morningstar  Mutual  Fund  Values,  Wiesenberger
Investment  Companies,  Schabacker  Investment  Management,  Barron's,  Money or
Forbes.  The Fund will either  quote our  relative  performance  compared to all
funds followed by the source or the relative performance compared to other funds
in the same category.  Each portfolio of the Fund may advertise  "total return."
The Fund calculates  total return by taking the total number of shares purchased
with a hypothetical  $1000  investment,  adding all additional  shares purchased
within the period  with  reinvested  dividends,  calculating  the value of those
shares at the end of the period and  dividing  the result by the  initial  $1000
investment.  For periods of more than one year, the  cumulative  total return is
then  adjusted  for the  number of years,  taking  compounding  into  account to
calculate average annual total return during that period.


         Total return is computed according to the following formula:

                                                                  n
P(1 + T) = ERV


where P = a hypothetical  initial payment of $1000, T = total return, n = number
of  years  and  ERV =  ending  redeemable  value.  Total  return  is  historical
information and is not intended to indicate future performance.

Yield of Balanced, Fixed-Income and California Tax-Exempt Portfolios

         The Balanced,  Fixed-Income  and California  Tax-Exempt  Portfolios may
also advertise  their yield from time to time.  Yield  quotations are historical
and are not intended to indicate future  performance.  Yield quotations refer to
the aggregate imputed  yield-to-maturity of each of the Portfolio's  investments
based on the market value as of the last day of a given  thirty-day or one-month
period less  accrued  expenses  (net of  reimbursements)  divided by the average
daily number of outstanding  shares entitled to receive  dividends times the net
asset value on the last day of the period, compounded on a "bond equivalent," or
semiannual basis. The yield is computed according to the following formula:
                                                                            6
Yield = 2 [(a-b + 1)  - 1]
                                       cd

where a = dividends  and interest  earned  during the period using the aggregate
imputed  yield to  maturity  for each of the  Portfolio's  investments  as noted
above:  b = expenses  accrued  for the period  (net of  reimbursement);  c = the
average daily number of shares  outstanding during the period that were entitled
to receive  dividends;  and d = the net asset value per share on the last day of
the period.

Effective Yield

         The Portfolio may also quote a tax equivalent yield which  demonstrates
the taxable yield necessary to produce an after-tax yield equivalent to that

B-10


                                       28
<PAGE>

of a fund which  invests in  tax-exempt  obligations.  Such yield is computed by
dividing  that  portion of our yield  (computed  as  indicated  above)  which is
tax-exempt  by one minus the highest  applicable  income tax rate and adding the
product to that portion of our yield that is not tax-exempt.

THE ADVISER

         Parnassus Investments acts as the Fund's investment adviser.  Under its
contract with the Fund,  the Adviser acts as  investment  adviser and subject to
the supervision of the Board of Trustees, directs the investments of the Fund in
accordance with its investment objective,  policies and limitations. The Adviser
also provides the Fund with all necessary  office  facilities  and personnel for
servicing the Fund's  investments and pays the salaries and fees of all officers
and all  Trustees of the Fund who are  "interested  persons"  and all  personnel
performing research relating to research and investment activities.  The Adviser
also  provides the  management  and  administrative  services  necessary for the
operation  of the Fund  including  supervising  relations  with  the  custodian,
transfer agent, independent accountants and attorneys. The Adviser also prepares
all  shareholder  communications,  maintains the Fund's  records,  registers the
Fund's shares under state and federal laws and does the staff work for the Board
of Trustees. Jerome L. Dodson owns all the outstanding stock of the Adviser and,
thus, can be considered the "control person" of the Adviser.

         For its services, the Fund, under an Investment Advisory Agreement (the
"Agreement") between the Fund and the Adviser,  pays the Adviser a fee, computed
and payable at the end of each month,  at the following  annual  percentages  of
each portfolio's average daily net assets: the Balanced Portfolio,  0.75% of the
first $30  million,  0.70% of the next $70 million and 0.65% of the amount above
$100  million.  For the  Fixed-Income  Portfolio and the  California  Tax-Exempt
Portfolio,  the fee is 0.50% of the first $200  million,  0.45% of the next $200
million and 0.40% of the amount above $400 million.

         The Agreement provides that the Adviser shall not be liable to the Fund
for any loss  sustained  by reason of the  purchase,  sale or  retention  of any
security,  whether or not such purchase, sale or retention shall have been based
upon its own investigation and research or upon  investigation and research made
by any  other  individual,  firm  or  corporation,  if  such  purchase,  sale or
retention  shall have been made and such other  individual,  firm or corporation
shall  have been  selected  in good  faith.  Nothing  contained  therein  shall,
however,  be construed to protect the Adviser  against any liability to the Fund
or its  security  holders by reason of willful  misfeasance,  bad faith or gross
negligence  in the  performance  of its  duties,  or by reason  of its  reckless
disregard of its obligations and duties under this agreement.

Portfolio Transactions and Brokerage

         The Agreement  states that in connection with its duties to arrange for
the purchase  and the sale of  securities  held in the  portfolio of the Fund by
placing  purchase  and sale orders for the Fund,  the Adviser  shall select such
broker-dealers  ("brokers") as shall, in the Adviser's judgement,  implement the
policy of the Fund to achieve "best execution", i.e. prompt and efficient

B-11


                                       27
<PAGE>

execution at the most favorable securities price. In making such selection,  the
Adviser is authorized in the  Agreement to consider the  reliability,  integrity
and  financial  condition  of the  broker.  The  Adviser is also  authorized  to
consider whether the broker provides  brokerage and/or research  services to the
Fund  and/or  other  accounts  of the  Adviser.  The  Agreement  states that the
commissions  paid to such brokers may be higher than  another  broker would have
charged if a good faith determination is made by the Adviser that the commission
is  reasonable in relation to the services  provided,  viewed in terms of either
that particular transaction or the Adviser's overall  responsibilities as to the
accounts as to which it  exercises  investment  discretion  and that the Adviser
shall use its judgement in determining  that the amount of commissions  paid are
reasonable in relation to the value of brokerage and research  services provided
and need not place or attempt to place specific dollar value on such services or
on the portion of commission rates reflecting such services.

         The Agreement  provides that to  demonstrate  that such  determinations
were in good faith and to show the overall  reasonableness  of commissions paid,
the  Adviser  shall be  prepared  to show  that  commissions  paid  were (i) for
purposes contemplated by the Agreement;  (ii) not allocated or paid for products
or services  which were  readily and  customarily  available  and offered to the
public on a commercial basis; and (iii) within a reasonable range as compared to
the rates charged by qualified brokers to other institutional  investors as such
rates may become known from available  information.  The Fund  recognizes in the
Agreement that, on any particular  transaction,  a higher than usual  commission
may be paid due to the difficulty of the transaction in question. The Adviser is
also  authorized in the  Agreement to consider  sales of shares of the Parnassus
Funds as a factor in the selection of brokers to execute brokerage and principal
transactions, subject to the requirements of "best execution", as defined above.

         The research services discussed above may be in written form or through
direct  contact with  individuals  and may include  information as to particular
companies and securities as well as market,  economic or institutional areas and
information assisting the Fund in the valuation of its investments. The research
which the Adviser receives for the Fund's brokerage commissions,  whether or not
useful to the Fund may be useful to the Adviser in managing  the accounts of the
Adviser's  other  advisory  clients.  Similarly,  the research  received for the
commissions of such accounts may be useful to the Fund.

         The  Adviser  may also use  brokerage  commissions  to  reduce  certain
expenses of the Fund subject to "best  execution." For example,  the Adviser may
enter into an agreement  to have a brokerage  firm pay part or all of the Fund's
custodian  fee since this  benefits  the  Fund's  shareholders.  Similarly,  the
Adviser may use brokerage  commissions to acquire computer software and hardware
(including  peripherals)  for use  with  the  Fund's  transfer  agent  and  fund
accounting work if such use benefits fund shareholders by reducing expenses.  If
a certain  piece of  equipment  is used for both Fund  purposes and for non-Fund
purposes by the Adviser (e.g. marketing),  the Adviser will allocate the cost on
a pro rata basis.  Recognizing  the  inherent  conflicts  in such an  allocation
process, the Adviser will exercise its best judgement in fairly apportioning the
costs.

         In the  over-the-counter  market,  securities are generally traded on a
"net" basis with dealers  acting as principal  for their own accounts  without a
stated  commission  although the price of the security usually includes a profit
to the dealer.  Money market instruments usually trade on a "net" basis as well.
On occasion,  certain money market instruments may be purchased directly from an
issuer in which case no  commissions  or  discounts  are paid.  In  underwritten
offerings, securities are purchased at a fixed price which includes an amount of
compensation  to the  underwriter,  generally  referred to as the  underwriter's
concession or discount.

         During  1993,  1994 and 1995,  the  Balanced  Portfolio  paid  $11,165,
$19,908 and $10,983 respectively in brokerage commissions. Of these amounts, the
following  was paid in  conjunction  with  research  services:  $11,165 in 1993,
$19,908 in 1994 and $10,983 in 1995. Neither the Fixed-Income  Portfolio nor the
California  Tax-Exempt  Portfolio paid  commissions in 1993,  1994 or 1995 since
these  portfolios buy their securities on a "net" basis that includes the dealer
mark-up.

NET ASSET VALUE

         In determining the net asset value of the Fund's shares,  common stocks
and bonds that are listed on  national  securities  exchanges  are valued at the
last sale price on the exchange on which each stock is principally  traded as of
the close of the New York Stock  Exchange  (which is currently  4:00 pm New York
time) or, in the absence of recorded sales, at the average of readily  available
closing bid and asked prices on such  exchanges.  Securities  traded on the NASD
National  Market  System are also valued at the last  recorded  sale price as of
4:00 pm New York time.  Other  unlisted  securities are valued at the quoted bid
prices in the  over-the-counter  market.  Securities  and other assets for which
market  quotations  are not readily  available are valued at their fair value as
determined  in good faith by the Adviser  under  procedures  established  by and
under  the  general  supervision  and  responsibility  of the  Fund's  Board  of
Trustees. Short-term investments which mature in less than 60 days are valued at
amortized  cost (unless the Board of Trustees  determines  that this method does
not represent fair value) if their  original  maturity was 60 days or less or by
amortizing the value as of the 61st day prior to maturity if their original term
to maturity exceeded 60 days.

SHAREHOLDER SERVICES

Systematic Withdrawal Plan

         A Systematic Withdrawal Plan (the "Plan") is available for shareholders
having shares of the Fund with a minimum value of $10,000. The plan provides for
monthly checks in an amount not less than $100 or quarterly  checks in an amount
not less than $200.

         Dividends and capital gains distributions on shares held under the Plan
are invested in additional full and fractional shares at net asset value.
Withdrawal payments should not be considered as dividends, yield or income. If

B-13


                                       30
<PAGE>

periodic withdrawals  continuously exceed reinvested dividends and capital gains
distributions,  the shareholder's  original  investment will be  correspondingly
reduced and ultimately exhausted.

         Furthermore, each withdrawal constitutes a redemption of shares and any
gain or loss  realized  must be  recognized  for  federal  income tax  purposes.
Although the shareholder  may invest $10,000 or more in a Systematic  Withdrawal
Plan,  withdrawals  made  concurrently  with purchases of additional  shares are
inadvisable  because  of  the  sales  charges  applicable  to  the  purchase  of
additional shares.

Tax-Sheltered Retirement Plans

         Through the  Distributor,  retirement  plans are available:  Individual
Retirement  Accounts  (IRAs)  and  Simplified  Employee  Pension  Plans  (SEPs).
Adoption  of such plans  should be on advice of legal  counsel  or tax  adviser.
Retirement  accounts  have  a  minimum  initial  investment  of  $500  and  each
subsequent  investment must be at least $50. For further  information  regarding
plan administration,  custodial fees and other details, investors should contact
the Distributor.

GENERAL

         The Fund's  Declaration of Trust permits the Fund to issue an unlimited
number of full and  fractional  shares of  beneficial  interest and to divide or
combine  the  shares to a greater  or lesser  number of shares  without  thereby
changing  the  proportionate   beneficial  interest  in  the  Fund.  Each  share
represents an interest in the Fund proportionately equal to the interest of each
other share.  Certificates representing shares will not be issued. Instead, each
shareholder  will receive an annual  statement and an additional  statement each
time there is a transaction in the account. These statements will be evidence of
ownership. Upon the Fund's liquidation, all shareholders would share pro rata in
the net assets available for distribution to shareholders. If additional classes
designated as "Series"  were created,  shares of each class would be entitled to
vote as a class only to the extent  required  by the  Investment  Company Act of
1940 or as  permitted  by the  Trustees.  Operating  expenses  will be allocated
fairly  among the  classes,  generally on the basis of relative net asset value.
This paragraph applies to all three portfolios.

         The Declaration of Trust contains an express  disclaimer of shareholder
liability  for  its  acts  or  obligations  and  requires  that  notice  of such
disclaimer be given in each agreement,  obligation or instrument entered into or
executed by the Fund or its  Trustees.  The  Declaration  of Trust  provides for
indemnification and reimbursement of expenses out of the Fund's property for any
shareholder held personally liable for its obligations. The Declaration of Trust
also provides that the Fund shall, upon request, assume the defense of any claim
made against any  shareholder  for any act or obligation of the Fund and satisfy
any judgement thereon.  Thus, while Massachusetts law permits a shareholder of a
trust  such as this to be held  personally  liable  as a partner  under  certain
circumstances,  the risk of a shareholder incurring financial loss on account of
shareholder liability is highly unlikely and is limited to

B-14


                                       31
<PAGE>

the relatively remote circumstances in which the Fund would be unable to meet
its obligations.

         The Declaration of Trust further provides that the Trustees will not be
liable for errors of  judgement  or mistakes of fact or law,  but nothing in the
Declaration of Trust protects a Trustee against any liability to which he or she
would otherwise be subject by reason of willful  misfeasance,  bad faith,  gross
negligence  or reckless  disregard of the duties  involved in the conduct of his
office.

APPENDIX

CORPORATE BOND RATINGS


Moody's Investors Service

         Aaa: Best quality.  These bonds carry the smallest degree of investment
risk  and are  generally  referred  to as  "gilt-edge".  Interest  payments  are
protected  by a large or by an  exceptionally  stable  margin and  principal  is
secure. While the various protective elements are likely to change, such changes
as can be  visualized  are most  unlikely  to impair  the  fundamentally  strong
position of such issues.

         Aa: High quality by all  standards.  Together with the Aaa group,  they
comprise what are generally known as high-grade bonds. They are rated lower than
the best  bonds  because  margins  of  protection  may not be as large as in Aaa
securities,  fluctuations of protective elements may be of greater amplitude, or
there may be other  elements  present  which  make the  long-term  risks  appear
somewhat greater than in Aaa securities.

         A: Upper-medium-grade obligations. Factors giving security to principal
and interest are considered adequate, but elements may be present which
suggest a susceptibility to impairment sometime in the future.

         Baa:  Medium-grade  obligations;  neither highly protected,  nor poorly
secured.  Interest  payments  and  principal  security  appear  adequate for the
present,   but   certain   protective   elements   may  be  lacking  or  may  be
characteristically  unreliable  over any great  length of time.  Such bonds lack
outstanding   investment   characteristics   and,  in  fact,  have   speculative
characteristics as well.

         Ba: Bonds which are rated Ba are judged to have  speculative  elements;
their future  cannot be  considered  as  well-assured.  Often the  protection of
interest  and  principal  payments  may be very  moderate,  and thereby not well
safeguarded  during  both good and bad times  over the  future.  Uncertainty  of
position characterizes bonds in this class.

         B:  Bonds  which  are rated B  generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.

Standard & Poor's Corporation:

         AAA: Highest grade obligations. They possess the ultimate degree of
protection as to principal and interest. Marketwise, they move with interest
rates and hence provide the maximum safety on all counts.

         AA: High-grade obligations. In the majority of instances, they differ
from AAA issues only in a small degree. Here, too, prices move with the long-
term money market.

B-16


                                       33
<PAGE>

         A: Upper-medium grade. They have considerable  investment strength, but
are not  entirely  free from  adverse  effects of changes in economic  and trade
conditions.  Interest and  principal  are regarded as safe.  They  predominantly
reflect money rates in their market behavior but, to some extent,  also economic
conditions.

         BBB: Medium-grade;  borderline between definitely sound obligations and
those where the  speculative  element  begins to  predominate.  These bonds have
adequate  asset  coverage and normally are protected by  satisfactory  earnings.
Their  susceptibility  to  changing  conditions,  particularly  to  depressions,
necessitates  constant  watching.  Marketwise,  the bonds are more responsive to
business and trade  conditions than to interest rates.  This group is the lowest
which qualifies for commercial bank investment.

         BB, B, CCC, CC: Debt rated BB, B, CCC, and CC is regarded,  on balance,
as predominantly  speculative with respect to capacity to pay interest and repay
principal in accordance  with the terms of the  obligation.  MOTA  indicates the
lowest degree of  speculation  and CC the highest degree of  speculation.  While
such debt will likely have some quality and  protective  characteristics,  these
are  outweighed  by large  uncertainties  of major  risk  exposures  to  adverse
conditions.


 MUNICIPAL BOND RATINGS

Moody's Investors Service:

         Aaa:  Municipal  bonds which are rated Aaa are judged to be of the best
quality.  They carry the smallest  degree of  investment  risk and are generally
referred to as "gilt edge." Interest  payments are protected by a large or by an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

         Aa:  Municipal bonds which are rated Aa are judged to be a high quality
by all standards.  Together with the Aaa group, they comprise what are generally
known as high grade  bonds.  They are rated  lower  than the best bonds  because
margins of protection may not be as large or fluctuation of protective  elements
may be of greater  amplitude or there may be other  elements  present which make
the long-term risks appear somewhat larger than in Aaa securities.

         A: Municipal bonds which are rated A possess many favorable  investment
attributes and are to be considered as upper medium grade  obligations.  Factors
giving security to principal and interest are considered adequate,  but elements
may be present which  suggest a  susceptibility  to  impairment  sometime in the
future.

         Baa: Bonds which are rated Baa are considered as medium grade
obligations; i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present, but
certain protective elements may be lacking or may be characteristically

B-17


                                       34
<PAGE>

unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and, in fact, have speculative characteristics as well.

         Conditional  Rating:  Bonds  for which the  security  depends  upon the
completion  of  some  act  or  the  fulfillment  of  some  condition  are  rated
conditionally.  These  are bonds  secured  by (a)  earnings  of  projects  under
construction,  (b) earnings of projects unseasoned in operation experience,  (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches.  Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

         Rating Refinements:  Moody's may apply numerical modifiers,  1, 2 and 3
in each generic  rating  classification  from Aa through B in its municipal bond
rating  system.  The modifier 1 indicates  that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-ranking;  and
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.

Standard & Poor's Corporation

         AAA:  Municipal  bonds rated AAA are highest  grade  obligations.  They
possess the ultimate  degree of protection as to principal and interest.  In the
market, they move with interest rates and, hence,  provide the maximum safety on
all counts.

         AA:  Municipal  bonds rated AA also qualify as  high-grade  obligations
and, in the majority of instances, differ from AAA issues only in small degree.
Here, too, prices move with the long-term money market.

         A:  Municipal  bonds rated A are regarded as upper medium  grade.  They
have  considerable  investment  strength but are not entirely  free from adverse
effects of changes in economic and trade conditions.  Interest and principal are
regarded  as safe.  They  predominantly  reflect  money  rates  in their  market
behavior, but also to some extent, economic conditions.

         BBB: Bonds rated BBB are regarded as having an adequate capacity to pay
principal  and  interest.  Whereas they  normally  exhibit  adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

         Provisional  Ratings:  The  letter  "p"  indicates  that the  rating is
provisional.  A  provisional  rating  assumes the  successful  completion of the
project being  financed by the bonds being rated and  indicates  that payment of
debt service  requirements is largely or entirely  dependent upon the successful
and timely completion of the project being financed by the bonds being rated and
indicates  that  payment of debt  service  requirements  is largely or  entirely
dependent upon the successful and timely completion of the project. This rating,
however,  while  addressing  credit  quality  subsequent  to  completion  of the
project, makes no comment on the likelihood of, or the risk of default

B-18


                                       35
<PAGE>

upon failure of, such completion. The investor should exercise his own judgement
with respect to such likelihood and risk.

Note: The S&P ratings may be modified by the addition of a plus (+) or minus (-)
sign to show relative standing within the major rating categories.

Fitch Investor's Service

         AAA:  Bonds and notes  rated AAA are  regarded  as being of the highest
quality,  with the obligor having an  extraordinary  ability to pay interest and
repay  principal  which is unlikely to be  affected  by  reasonably  foreseeable
events.

         AA: Bonds and notes rated AA are regarded as high quality  obligations.
The obligor's ability to pay interest and repay principal is strong,  but may be
more vulnerable to adverse changes in economic conditions and circumstances than
bonds and notes with higher ratings.

         A: Bonds and notes rated A are regarded as being of good  quality.  The
obligor's ability to pay interest and repay principal is strong, but may be more
vulnerable to adverse  changes in economic  conditions  and  circumstances  than
bonds and notes with higher ratings.

         BBB:  Bonds and notes rated BBB are  regarded as being of  satisfactory
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however, are more likely to weaken this ability than bonds with higher ratings.

Note:  Fitch  ratings may be modified by the addition of a plus (+) or minus (-)
sign to show relative  standing  within the major rating  categories.  These are
refinements more closely reflecting strengths and weaknesses,  and are not to be
used as trend indicators.

Item 27.Indemnification

         Under the provisions of the Fund's  Declaration  of Trust,  the Fund is
permitted to indemnify its present or former Trustees,  officers,  employees and
certain other agents against liability  incurred in such capacity except that no
indemnification  may be paid to protect such a person from  liability  resulting
from willful  misfeasance,  bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of his or her office  ("disabling  conduct").
Indemnification  therefore  requires a determination that the indemnitee had not
engaged in  disabling  conduct.  The required  determination  may be made by the
final  decision  of the court or other  body  before  which the  proceeding  was
brought or,  lacking such a decision,  by the  reasonable  determination  of the
Fund's  Trustees,  based upon a review of the facts that is made by (a) the vote
of a majority of a quorum of Trustees who are neither  "interested  persons" nor
parties  to the  proceeding  or (b) an  independent  legal  counsel in a written
opinion.

         Insofar as  indemnification  for liability arising under the Securities
Act of 1933 may be permitted to Trustees,  officers and  controlling  persons of
the  registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a Trustee,  officer or controlling  person of the registrant


                                       38
<PAGE>

in the successful defense of any action, suit or proceeding) is asserted by such
Trustee,  officer or controlling  person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction  the  question  of whether  such  indemnification  by it is against
public  policy  as  expressed  in the Act  and  will be  governed  by the  final
adjudication of such issue.

                  Exhibit 16


Calculation of Parnassus Income Fund Total Return

SEC  regulations  provide for  calculating  the one,  five and ten year  average
annual total return figures for the Fund. However, the Parnassus Income Fund has
only been  operating  for three years and four months so we  calculate  only the
one-year and life-of-the-fund  average annual total returns. The Fund calculates
its average annual total return  quotations for the periods ended on the date of
the most recent balance sheet included in the registration  statement by finding
the average  annual  compounded  rates of return  that would  equate the initial
amount  invested  to the ending  redeemable  value  according  to the  following
formula:

P(1+T)n = ERV

Where:   P        =        a hypothetical initial payment of $1,000

         T        =        average annual total return

         n        =        number of years

         ERV      =ending redeemable value of a hypothetical $1,000
payment made at the beginning of the periods (or
fractional portion thereof);

These calculations incorporate the following assumptions:

1. The maximum sales load (or other charges  deducted from payments) is deducted
from the initial $1,000 payment.

2. All  dividends  and  distributions  by the Fund are  reinvested  at the price
stated in the prospectus on the reinvestment dates during the period,  i.e., any
sales load charged upon reinvestment of dividends would be reflected.

3. All recurring fees, if any, charged to all shareholder accounts are
included.

4. The ending  redeemable value assumes a complete  redemption at the end of the
year periods and the deduction of all  nonrecurring  charges deducted at the end
of each period.
