Chairman's Letter




Dear PIMCO Funds Shareholder:


The financial markets generated outstanding returns for investors in 1997. For
the one-year period ended December 31, 1997, the stock market, as measured by
the Standard & Poor's 500 Index of stocks, rose 33.4%. The overall bond market,
as measured by the Lehman Aggregate Bond Index, posted a 9.7% return.

Positive Market Conditions.  The last twelve months have been an exciting time
for investors, as the value of many investment portfolios grew substantially.
However, the stock market provided more than its share of nervous moments. In
March, the overall stock market fell nearly 10%, based on unfounded fears of
rising inflation. Then, in reaction to the escalating financial crisis in
Southeast Asia, the Dow Jones Industrial Average fell 554 points on October
27th. But, as we have seen on so many occasions in recent years, investors
viewed the market declines as buying opportunities, and stock prices rebounded
sharply.

As we anticipated, bond yields fluctuated in a fairly narrow range in 1997. We
expect this trend to persist, should long-term interest rates remain between 5
and 7% through the year 2000. Given this environment, we believe bonds will
continue to post relatively strong returns in the coming years.

Looking Ahead.  As we head into 1998, there are signs that the financial markets
could provide solid, but less spectacular returns. We are in the midst of an
economy that has grown at a steady pace, but not so fast that it has triggered
an increase in inflation. This phenomenon has been a major factor in the stock
and bond markets' ascent during the past several years.

However, it is highly unlikely that we will see a repeat of the recent dramatic
stock market gains. Historically, from 1926-1997, stocks have posted an annual
11% return, yet for the three-year period ended December 31, 1997, stocks have
risen 31% annually. As a result, going forward it will be important to
adequately diversify and maintain realistic expectations about your investments.

On the next page, you will find a more complete review of the stock and bond
markets, followed by a recent interview with David Breed, from the management
team of PIMCO Capital Appreciation and Mid Cap Growth Funds. We have also
provided an overview of Fund performance for the six-month period ended December
31, 1997, including specific market commentary.

As always, we appreciate the trust you have placed in us, and we will continue
to work hard to help you meet your investing needs. If you have any questions
regarding your investment, please contact your account manager or one of our
representatives at 1-800-927-4648, or visit our website at www.pimcofunds.com.



Sincerely,



/s/ William D. Cvengros

Market Review



The Stock Market

A Record-Breaking year

All told, 1997 was another outstanding year in the equity market. For the first
time in its history, the overall stock market posted annual back-to-back-to-back
20%+ returns. During that three-year period the market rose 125%--its best
cumulative performance since the 1933-1935 period.

Despite the largest single-day point drop in the Dow, stocks rebounded and
posted outstanding results in 1997.

     1997 was largely known as the year of large-cap stocks, specifically the
largest 50 companies. For much of the year investors flocked to these highly
liquid, household names, as they looked for solace amid market volatility. The
exception occurred during the third quarter of 1997, as small- and mid-cap
stocks led the pack due to concerns that large-cap stocks were becoming
overvalued. However, when the Asian currency crisis escalated in the fourth
quarter, large-cap stocks were again the best performers, in particular stocks
of companies with minimal reliance on overseas business.

     Aside from the historic bull run, the other noteworthy news has been
the market's volatility. During 1997, the market rose or fell more than one
percent from the previous day 32% of the time. That was more than double the
1996 level and triple that of 1995. Based on current market conditions there is
little indication that this volatility will subside in the near future.

     The question on the minds of many investors is how much longer can the
stock market's ascent continue? When the bull market began in October 1990, the
Dow Jones Industrial Average stood at 2365. In July 1997, the Dow eclipsed 8000
and ended the year at 7908. During that seven year period the stock market has
only had one correction of over 10%--another record.

     As we look ahead, we remain cautiously optimistic about the prospects for
the stock market. The optimism lies in the fact that the current environment is
positive and corporate profits, especially in companies with minimal exposure to
Asian markets, are generally healthy. However, if the Asian situation
intensifies and leads to disappointing corporate earnings, we could see a
reversal of fortune. Therefore, it's important for investors to ensure that
their portfolios are adequately diversified, and to maintain a long-term outlook
during periods of market volatility.


The Bond Market

A Strong Rebound Takes Place

In our report to shareholders six months ago, we stated that "the prospects for
the bond market are bright." At the time, our optimism may have looked like
wishful thinking. In March, the Federal Reserve Board had raised interest rates
1/4 of a percentage point as a preemptive strike against inflation. This caused
long-term interest rates to surge above 7.1% by the end of the first quarter of
1997.

After surging in early 1997 interest rates fell dramatically--causing bond
prices to rise.

                                     6.154
                                     6.156
                                     6.114
                                     6.034
                                     6.055

     However, our forecast was correct, as the bond market shook off its early-
year losses and rebounded dramatically. By the end of 1997, long-term interest
rates had plunged to 5.9%. Virtually every sector of the bond market
participated in the rally, led by high yield bonds.

     There were several factors that contributed to the bond market's rebound,
including the strong U.S. dollar, signs of a slowing U.S. economy due to the
Asian financial crisis, low inflation, and a subsequent reduced threat of a
Federal Reserve interest rate hike. In addition, the volatility in the stock
market caused many investors to reallocate assets into bonds. This led to
positive supply-and-demand considerations for bonds.

     Looking ahead, we believe that interest rates will continue to fall, but
not at the pace we have experienced in the past few months. Should the economy
experience a few quarters of sluggish 1% growth, the yield on long-term
Treasuries could drop to 5.5%. This would lead to strong returns in the bond
market, especially relative to the low inflationary environment we anticipate
going forward.

     In terms of specific sectors of the market, we foresee attractive
opportunities in lower-coupon mortgage securities, provided that long-term
interest rates do not fall below 5.5%. Emerging market debt in selective
countries might also become attractive in 1998.

Despite the increased volatility in the stock market due to the crisis in
Southeast Asia, the mutual funds managed by PIMCO Advisors' Cadence Capital
Management continue to post outstanding results. While past performance is no
guarantee of future results, both the PIMCO Capital Appreciation and Mid Cap
Growth Funds have outperformed their respective indices over the 1-, 3-, 5-year
and since inception periods ended December 31, 1997. We spoke with David Breed,
Chief Investment Officer at Cadence, for an update on the Funds.


Q:   What's the secret behind your Funds' outstanding performance records?

A:   First, we follow a "growth-at-a-reasonable-price" investment strategy. In
     other words, we look for strong growth companies, but we won't pay through
     the nose to get them. Second, as primarily an institutional manager we
     strictly adhere to our investment strategy. We simply will not jeopardize
     our portfolios by following the latest hot industry or investment trend.


Q:   Can you briefly describe your investment process?

A:   Our investment strategy begins with taking a universe of roughly 4,000
     stocks, and applying a systematic stock selection process. This helps us
     rank each security by growth and price considerations, such as expected
     earnings per share growth and price-to-earnings ratio. We then conduct
     fundamental research to select about 400 companies we believe can sustain
     their growth rates.


Q:   When do you sell a stock?

A:   Our decision to sell a stock is as disciplined as our decision to buy a
     stock. To ensure adequate diversification we automatically trim holdings
     that grow to more than 2% of a fund's portfolio. In addition, we
     continually monitor and analyze our portfolios for holdings that we think
     should be sold. We consider selling a stock when it shows declining
     earnings expectations or announces a negative earnings surprise. A stock is
     also sold when it reaches an excessive relative valuation, a practice that
     has won praise from Morningstar for its tax efficiency.


Q:   Can you explain how selling certain stocks results in tax efficiency?

A:   We help to offset realized capital gains by quickly selling off holdings
     that are underperforming. This reduces the amount of taxable capital gains
     distributions, and has helped to improve our funds' after-tax return
     potential.


Q:   How are you positioning the Capital Appreciation Fund given the high
     valuations in the large-cap market?

A:   We have a smaller market capitalization in the Fund relative to its
     benchmark, the S&P 500 Index. We have done this in reaction to the high
     prices of many large-cap stocks, and our belief that there is risk to the
     earnings of larger multinational corporations as a result of the crisis in
     Southeast Asia. We believe a more domestically-oriented portfolio that is
     not heavily weighted in multinationals will perform relatively well in a
     market that is affected by overseas turbulence.


Q:   What is your outlook for the mid-cap market and the Mid Cap Growth Fund?

A:   Generally, mid-caps are not as exposed to the Asian crisis as larger-cap
     stocks. This is especially true among the large multinational companies
     that rely on foreign sales to boost their earnings. In addition, as a
     whole, mid-caps are well-positioned to participate in the ongoing
     acquisition wave, which we expect to be prevalent in 1998 as companies look
     for ways to boost their earnings in the aftermath of Southeast Asia.


Q:   What sets Cadence Capital Management apart from other investment managers?

A:   Our "blended" approach of investing in growth stocks that are reasonably
     priced differentiates us from many of our peers. And given the high
     valuations in many sectors of the stock market, we believe this strategy
     will be particularly beneficial in the coming year.


The views of Mr. Breed are not indicative of any future performance of any PIMCO
Fund. Refer to pages 6 and 7 for more complete performance information on the
Capital Appreciation and Mid Cap Growth Funds.

Past performance is not an indication of future results. The line graph above
assumes the investment of $5,000,000 on 6/1/93, the Fund's Institutional Class
inception, compared to the Morgan Stanley Capital International (MSCI) Emerging
Markets Free Index, an unmanaged market index. The performance of the
Administrative Class (shown above) reflects the payment of a service fee in an
amount not to exceed 0.25% on an annualized basis. The Administrative Class
commenced operations on 11/1/94. The performance since inception (shown above)
begins 11/1/94. The Fund may invest in foreign securities which involve
potentially higher risks including foreign currency fluctuations and political
or economic uncertainty.

- --------------------------------------------------------------------------------
PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . For the six-month semiannual period, Institutional Class shares of the
  Emerging Markets Fund declined 16.12%, while Administrative Class shares fell
  16.27%. Although absolute returns were negative, relative performance was
  strong. The Fund led the average return of offerings with the same objective
  (as measured by the Lipper Emerging Markets Fund Average) which fell 19.10%,
  and widely outpaced the negative 24.91% return of its performance benchmark,
  the MSCI Emerging Markets Index.

 . The past six months were historically poor for emerging market countries. The
  economic crisis in Southeast Asia, led by the collapse of the Korean won and
  the Thai baht, dragged down all of emerging Asia, as foreign debt became
  increasingly hard to service from local resources. The Fund had no weighting
  in Korea for the entire fourth quarter, which helped it outperform much of the
  competition.

 . The Fund's best performers were located outside of Asia, including Eastern
  Europe. One winner was Matav, the largest telecommunications service provider
  in Hungary, which posted solid returns. Matav is currently unrolling a
  nationwide support system for integrated billing and call collection that is
  expected to lower administrative costs and enhance productivity.

 . While most Asian markets still look weak, the manager believes there will be
  investment opportunities in the region going forward. Collapsed currencies
  make Asian goods highly competitive in world markets. In addition, there has
  been a rise in consumer expectations stemming from higher educational levels
  and real income growth in the region over the past 15 years. Finally, at the
  most basic economic level, there is always demand for food, building
  materials, transportation, and other everyday needs. Well run companies that
  operate in these sectors will recover.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . For the six months ended December 31, 1997, the International Developed Fund
  posted a negative 7.09% return for Institutional Class shares, and a negative
  7.17% for Administrative Class shares. However, these returns were better than
  the 8.36% decline in the return of the MSCI EAFE Index, the Fund's benchmark.

 . For the period, international markets produced mixed returns. Most European
  markets had relatively strong results, while Asian markets, harmed by the
  growing currency crisis, declined severely. The Fund benefited from
  underweighting many of those falling markets, including Japan, while
  emphasizing some countries that performed particularly well, such as
  Switzerland.

 . Recent winning holdings included Lloyds TSB Group PLC, a U.K.-based banking
  and financial services holding company. Its stock price rose on news that Bank
  of New York and Beneficial Corp. will acquire one of Lloyd's business lines.
  Another success was Societe Generale, a banking and financial services company
  headquartered in Paris. Management continued to make great progress in
  improving the company's financial strength, as evidenced by its higher-than-
  expected commission growth from both capital markets and the retail network.

 . As a whole, the weakness in Asia has taken the luster off of international
  stock prices. As a result, these markets have become more fairly valued
  compared to the United States. Therefore, the Fund's manager believes that
  exposure to international stocks continues to make sense for investors looking
  to diversify their portfolios.

Past performance is not an indication of future results. The line graph above
assumes the investment of $5,000,000 on 4/1/91, the first full month following
the Fund's Institutional Class inception on 3/8/91, compared to the S&P 500
Index, an unmanaged market index. The performance of the Administrative Class
(shown above) reflects the payment of a service fee in an amount not to exceed
0.25% on an annualized basis. The Administrative Class commenced operations on
7/31/96.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . The Capital Appreciation Fund posted outstanding results for the six-month
  period ended December 31, 1997, with returns of 16.17% for Institutional Class
  shares, and 16.02% for Administrative Class shares. These results solidly
  bested the 10.58% return of the S&P 500 Index, and the 8.94% average return of
  funds with the same objective (as measured by the Lipper Capital Appreciation
  Fund Average).

 . The Fund benefited from its large exposure to the retail sector, particularly
  through its holdings in the supermarket industry where technological and
  logistical upgrades have led to higher profits at many supermarkets. One
  example of this trend was the Fund's top holding, retail supermarket chain
  Kroger. The company has improved its operating and financial performance and
  has made good progress toward reducing its debt.

 . Another winner for the Fund was Carnival Corp., which announced its sixth
  dividend increase in seven years. This positive news stemmed from continued
  heavy consumer demand and strong pricing activity. The company also unveiled
  plans to expand its fleet over the next three years with seven new ships.

 . One factor that hindered the Fund's performance in the fourth quarter was its
  overweighted position in the energy sector. Falling oil prices at the end of
  1997 resulted in declining stock prices for oil and natural gas drilling
  companies, including Fund holding Nabors Industries, Inc.

Past performance is not an indication of future results. The line graph above
assumes the investment of $5,000,000 on 9/1/91, the first full month following
the Fund's Institutional Class inception on 8/26/91, compared to the S&P Mid-Cap
Index, an unmanaged market index. The performance of the Administrative Class
(shown above) reflects the payment of a service fee in an amount not to exceed
0.25% on an annualized basis. The Administrative Class commenced operations on
11/30/94.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------


 .    The Mid Cap Growth Fund posted excellent results for the semiannual period
     ended December 31, 1997, with returns of 17.83% and 17.72%, respectively,
     for Institutional and Administrative Class shares. These results edged the
     17.05% return of the S&P Mid-Cap Index and significantly led the 10.56%
     average return of funds with the same objective (as measured by the Lipper
     Mid-Cap Fund Average).

 .    Financial services represented the Fund's largest weighting and top
     performing sector during the period. Strong results were aided by the
     acquisition trend within the banking industry, as evidenced by the
     performance of one of the Fund's largest holdings, Cullen/Frost Bankers,
     Inc., which purchased Harrisburg Bancshares, Inc., a smaller competitor.

 .    Returns were also helped by the strong performance of milk and food
     distributor Dean Foods. The company announced a restructuring plan in 1996
     following several quarters of underperformance. Since then, it has
     consistently beaten analysts' earnings estimates.

 .    Detracting from Fund performance, especially during the fourth quarter, was
     its overweighted position in the energy sector. Falling oil prices at the
     end of 1997 resulted in declining stock prices for oil and natural gas
     drilling companies. The sell-off in oil stemmed from concerns about a
     possible oversupply and decreasing demand in Southeast Asia.

                                                       1997 Semiannual Report 7

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . Investors in the Micro Cap Growth Fund enjoyed very strong performance
  results over the six months ended December 31, 1997. The Fund's
  Institutional Class shares returned 20.99% while Administrative Class
  shares rose 20.85%. These returns easily surpassed the Russell 2000 Index
  and the average micro cap fund (as measured by the Lipper Micro-Cap Fund
  Average) which increased 11.04% and 16.57%, respectively.
  
 . The Fund's overweight position in financial services companies boosted
  performance. These firms benefited from low interest rates, reasonable
  stock price multiples and an active market for mergers and acquisitions. A
  leading holding for the Fund was Abington Bancorp, Inc.
  
 . While representing a relatively small proportion of the Fund's investment
  portfolio, the health care sector also posted strong gains. Driving much of
  the group's favorable relative performance were Osteotech, Inc. and
  Sheridan Healthcare, Inc.
  
 . The Fund also held a significant stake in consumer discretionary stocks
  which delivered mixed returns overall. While holdings such as Pillowtex
  Corp., Movado Group, Inc. and Virco Manufacturing Corp. were significant
  contributors, disappointing earnings growth prompted the manager to trim
  the Fund's position in this sector by selling less successful names like
  American Woodmark Corp. and Chattem, Inc.

Past performance is not an indication of future results. The line graph above
assumes the investment of $5,000,000 on 2/1/91, the first full month following
the Fund's Institutional Class inception on 1/17/91, compared to the Russell
2000 Index, an unmanaged market index. The performance of the Administrative
Class (shown above) reflects the payment of a service fee in an amount not to
exceed 0.25% on an annualized basis. The Administrative Class commenced
operations on 9/27/95.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . Small Cap Growth Fund shareholders experienced favorable returns over the
  semiannual period ended December 31, 1997, a period in which Institutional
  and Administrative Class shares returned 13.20% and 13.03%, respectively.
  These results bested the 11.04% return of the Russell 2000 Index of
  small-cap stocks, as well as the 10.55% average return of funds with the
  same objective (the Lipper Small-Cap Fund Average).
  
 . Stocks in defensive sectors, such as financial services and utilities
  provided the strongest relative returns in 1997's second half. In addition,
  highly liquid, stable growth stocks were rewarded, as demonstrated by the
  double-digit returns of health care and consumer staples.
  
 . The Fund's largest sector position was financial services. During the
  latter half of the year, companies in this sector benefited from low
  interest rates, reasonable price multiples and industry consolidation.
  Successful holdings included Associated Banc-Corp, Colonial BancGroup, Inc.
  and Protective Life Corp. Consumer discretionary stocks also contributed to
  performance. Several holdings in this sector saw significant price gains,
  including food and general merchandise food store chain Fred Meyer, Inc.;
  furniture maker Ethan Allen Interiors, Inc.; and home furnishings specialty
  store Pier 1 Imports, Inc.
  
 . Detracting from relative returns were holdings in the energy sector. The
  poor performance in this sector can be attributed to energy prices falling
  quickly at the end of the year on fears that a significant economic
  slowdown in Asia will reduce global demand for energy, allowing supply to
  build up, and depressing energy prices.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . The latter six months of 1997 saw the Core Equity Fund's Institutional and
  Administrative Class shares return a solid 11.29% and 11.17%, respectively. In
  comparison, the S&P 500 Index returned a lesser 10.58%, and the Fund also
  outperformed the 9.15% average return of funds with the same investment
  objective (as measured by the Lipper Growth Fund Average).

 . The Fund maintained its large exposure to the healthcare sector during the
  period, as the world's aging population continued to accelerate demand for
  certain prescription medicines and healthcare services. HBO & Company, a
  provider of computerized information systems to the healthcare sector and the
  Fund's top holding, illustrated the healthcare industry's good fortunes, as it
  posted excellent results during the fourth quarter.

 . AT&T Corp., which outperformed all other stocks in the Dow Jones Industrial
  Average during the latter half of 1997, also boosted performance. AT&T's
  success was attributed to the company's new Chief Executive Officer, Michael
  Armstrong, who is moving swiftly to reverse AT&T's profit decline.

 . Although the healthcare sector in general stood out as a solid performer, one
  particular stock in this industry hampered results. Oxford Health Plans, Inc.,
  one of the nation's largest HMOs, surprised investors when it announced that
  earnings would fall significantly short of expectations due to higher medical
  costs. Oxford's shares lost nearly half of their value as a result of this
  news.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . The Mid Cap Equity Fund's Institutional Class shares posted disappointing
  results for the semiannual period ended December 31, 1997. The Fund's 8.52%
  return lagged both the 17.05% advance of the S&P Mid-Cap Index, and the
  average mid-cap fund, which posted a 10.56% return (as measured by the Lipper
  Mid-Cap Fund Average).

 . The finance sector was the best performing industry for the Fund during the
  second half of 1997, with several factors adding to favorable results. Most
  important was the declining interest rate environment, as the yield on the 30-
  year Treasury bond decreased from 6.4% to 5.9%. Financial sector stocks also
  received a boost from a very favorable merger and acquisition trend. Dime
  Bancorp, Inc. benefited from this trend through its acquisition of North
  American Mortgage Co., which was warmly received by analysts and investors.

 . Fred Meyer, Inc., a multi-product retail chain, was another Fund holding that
  performed well through acquisition. Its stock traded higher on announced plans
  to buy Quality Food Centers, Inc. and Ralph's Grocery Co. The combination will
  create one of the largest supermarket companies in the United States.

 . Less positive for performance was the Fund's overweighted exposure to the
  technology sector, which performed poorly as a result of the Southeast Asian
  currency crisis. Many technology stocks declined as the market quickly
  concluded that 1998 growth in global technology spending would be negatively
  impacted due to lower sales in Asian countries.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . The Equity Income Fund delivered strong performance for the six months ended
  December 31, 1997. Specifically, the Fund's Institutional and Administrative
  Class shares returned 14.13% and 14.01%, respectively. These returns handily
  outperformed the S&P 500 Index return of 10.58%, and the 11.07% average return
  of funds with the same objective (as measured by the Lipper Equity Income Fund
  Average).

 . During the third quarter of 1997, the stock market as a whole did very well.
  Effective stock selection further enhanced performance, most notably from
  holdings in the finance and consumer staples sectors. Examples of stocks that
  buoyed returns during the period were Bankers Trust, Bear Stearns, Chase
  Manhattan and Maytag.

 . In the turbulent fourth quarter, the Asian crisis caused investors to quickly
  reassess the short-term prospects for many sectors of the marketplace. During
  this period, Fund performance was boosted by successful sector selection,
  including an overweighted position in the utility sector and an underweighted
  allocation to technology stocks. In particular, the Fund benefited from
  holdings such as Southern New England Telecommunications, which was subject to
  takeover rumors. PG&E Corp., PNC Bank Corp., RJR Nabisco and Supervalu also
  performed well.

 . On the downside, Fund performance was hurt somewhat by holdings such as
  Capstead Mortgage and Phelps Dodge. In addition, the Fund suffered from the
  continuing lag of value versus growth stocks.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . Like many of its competitors, the PIMCO Value Fund had trouble keeping up with
  the more growth-oriented S&P 500 Index for the six months ended December 31,
  1997. During this period the Fund's Institutional Class shares returned
  10.17%, outperforming the 9.87% average return of funds with the same
  objective (as measured by the Lipper Growth and Income Fund Average), but
  narrowly trailing the S&P 500 Index return of 10.58%.

 . The Fund posted strong third quarter 1997 results. Much of this success was
  due to better broad market performance. Earlier in 1997, the stock market's
  advancers were clustered among the largest stocks in the S&P 500 Index. But,
  during the third quarter, a wider distribution of stocks performed well.

 . Among the Fund's better performers was Adobe Systems, Inc., which reported
  better-than-expected earnings based on strong sales of its desktop publishing
  software, and plans for a share buyback.

 . The fourth quarter saw investors return to large-cap, highly liquid stocks as
  mounting Asian financial turmoil caused earnings fears. Overall, stock
  selection was fairly neutral during these three months, with the exception of
  some significant losses in the health care and consumer staples sector; in
  particular, Foundation Health and IBP hurt performance. Fortunately, the
  Fund's policy of wide diversification prevented any single holding or sector
  from causing extensive damage.

- --------------------------------------------------------------------------------
PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . Shareholders of the Small Cap Value Fund experienced very strong returns over
  the six months ended December 31, 1997, a period in which Institutional and
  Administrative Class shares returned 17.57% and 17.35%, respectively. These
  results compare very favorably to the 11.04% return of the Fund's benchmark
  (the Russell 2000 Index) and the 10.55% average return of funds with the same
  objective (the Lipper Small-Cap Fund Average).

 . Much of the Fund's success can be traced to the third quarter of 1997. While
  the majority of the market's gains have been contained to large-cap stocks,
  the third quarter saw a small-cap stock surge. The Fund benefited heavily from
  this rally, posting a 15% return for the quarter.

 . Financial services holdings were strong contributors, as takeovers in the
  banking and brokerage industries drove up stock prices. Also benefiting from
  merger activity was the Fund's position in Computer Data Systems, Inc. This
  provider of information technology solutions saw its share price surge on the
  announced takeover plan of Affiliated Computer Service, Inc.

 . The fourth quarter saw Asian financial woes frighten U.S. investors into a
  flight back to size and liquidity. As a result, the Russell 2000 Index fell
  3.4% during the fourth quarter. However, the Fund generated a positive return
  during the period largely because most of the damage in the small-cap market
  was done to growth-versus more value-oriented stocks. Value sectors that
  boosted relative returns included utilities and building related stocks.

Past performance is not an indication of future results. The line graph above
assumes the investment of $5,000,000 on 1/1/92, the first full month following
the Fund's Institutional Class inception on 12/30/91, compared to the S&P 500
Index, an unmanaged market index. The performance of the Administrative Class
(shown above) reflects the payment of a service fee in an amount not to exceed
0.25% on an annual basis. The Administrative Class commenced operations on
8/21/97.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

 . The Enhanced Equity Fund delivered above-index results for the six-month
  period ended December 31, 1997, with returns of 11.29% for Institutional Class
  shares versus 10.58% for the S&P 500 Index and 9.87% for funds with the same
  investment objective (as measured by the Lipper Growth & Income Fund Average).

 . Positives for the Fund included holdings in the airline and utilities sectors
  which posted significant gains. The airline industry's efforts to trim costs
  and maintain favorable pricing paid off, as the stocks of the entire group
  were strong. The Fund's utility stocks also performed well, as the steady drop
  in the yield on the 30-year Treasury bond fueled demand for interest-sensitive
  stocks. The perception that utilities have less downside volatility than other
  stocks also helped them gain favor among cautious investors.

 . Other top performing sectors for the Fund were healthcare, shelter, and
  retail. In addition, throughout 1997 the Fund's financial services stocks were
  strong performers. Mergers, solid profit growth, and declining interest rates
  propelled many banks and securities brokers.

 . One area that hurt the Fund's performance was its exposure to the technology
  sector. These stocks declined due to signs of weakening demand for products in
  overseas markets resulting from the economic crisis in Asia. A modest above-
  index exposure to technology, combined with weak stock selection, further
  dragged down the Fund's returns.

Past performance is not an indication of future results. The line graph above
assumes the investment of $5,000,000 on 7/1/92, the first full month following
the Fund's Institutional Class inception on 6/25/92, compared to a static 60/40
blend of the Standard and Poor's 500 Index and the Lehman Brothers Aggregate
Bond Index, and the Lipper Balanced Index, each an unmanaged market index. The
Fund may invest in foreign securities which involve potentially higher risks
including foreign currency fluctuations and political or economic uncertainty.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------


 .    The Balanced Fund turned in solid results for the six-month period ended
     December 31, 1997, posting a 10.22% return which was significantly higher
     than the 7.89% average return of funds with the same objective (as measured
     by the Lipper Balanced Fund Average).

 .    The Fund's manager maintained an allocation mix of 60% stocks and 40% bonds
     and looked to add value relative to its Lipper benchmark by actively
     managing both its equity and fixed income components.

 .    Contributing to favorable stock performance was PNC Bank Corp. which
     advanced on positive market response to efforts to expand its business mix
     and exercise more disciplined risk management. PG&E Corp., a holding
     company that markets energy services, was another stock success story. As
     the Asian economic crisis unfolded, investors were attracted to the
     domestically-based earnings of the company.

 .    Favorable fixed income returns were paced by an above-index duration rating
     which benefited performance as yields declined. The Fund's significant
     allocation to mortgage-backed securities was also a plus as the yield
     advantage of low-coupon mortgages led the sector to outperform comparable
     duration Treasuries.

 .    Less positive for Fund performance was an overweighted position in energy
     stocks which, outside of PG&E Corp., generally underperformed the market,
     and several holdings in the consumer staples sector also lagged the market.

Notes to Financial Statements

December 31, 1997 (Unaudited)


1. Organization 

PIMCO Funds: Multi-Manager Series (the "Trust"), formerly known as PIMCO Funds:
Equity Advisors Series, was established as a Massachusetts business trust on
August 24, 1990. The Trust is registered under the Investment Company Act of
1940, as amended, as an open-end management investment company. The Trust
currently consists of twenty two separate investment funds (the "Funds"): the
Equity Income Fund; the Renaissance Fund; the Small Cap Value Fund; the Value
Fund; the Capital Appreciation Fund; the Mid Cap Growth Fund; the Micro Cap
Growth Fund; the Small Cap Growth Fund; the Core Equity Fund; the Mid Cap Equity
Fund; the Innovation Fund; the Enhanced Equity Fund; the Emerging Markets Fund;
the International Fund; the International Developed Fund; the Target Fund; the
Tax Exempt Fund; the Growth Fund; the Opportunity Fund; the Precious Metals
Fund; the Structured Emerging Markets Fund; and the Balanced Fund. The
Structured Emerging Markets Fund had not commenced operations as of December 31,
1997. As used in the financial statements, "Institutional Classes" refers to the
Institutional and Administrative Classes and "Retail Classes" refers to the A,
B, and C Classes of the Trust.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently
followed by the Trust in preparation of its financial statements. These policies
are in conformity with generally accepted accounting principles. The preparation
of financial statements in accordance with generally accepted accounting
principles requires management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results
could differ from those estimates.

Security Valuation. Portfolio securities and other financial instruments for
which market quotations are readily available are stated at market value. Market
value is determined on the basis of last reported sales prices, or if no sales
are reported, as is the case for most securities traded over-the-counter, the
mean between representative bid and asked quotations obtained from a quotation
reporting system or from established market makers. Foreign currency amounts are
converted to U.S. dollars using foreign exchange quotations received from
independent dealers. Short-term investments having a maturity of 60 days or less
are valued at amortized cost, which approximates market value. Certain fixed
income securities for which daily market quotations are not readily available
may be valued, pursuant to guidelines established by the Board of Trustees, with
reference to fixed income securities whose prices are more readily obtainable.

Securities Transactions and Investment Income. Securities transactions are
recorded as of the trade date. Securities purchased or sold on a when-issued or
delayed-delivery basis may be settled a month or more after the trade date.
Realized gains and losses from securities sold are recorded on the identified
cost basis. Dividend income is recorded on the ex-dividend date, except certain
dividends from foreign securities where the ex-dividend date may have passed,
are recorded as soon as the Fund is informed of the ex-dividend date. Interest
income, adjusted for the accretion of discounts and amortization of premiums, is
recorded on the accrual basis.

Dividends and Distributions to Shareholders. Dividends from net investment
income, if any, are declared and paid quarterly to shareholders of record by the
Equity Income, Value and Balanced Funds. Dividends from net investment income,
if any, are declared and paid at least annually to shareholders of record by the
other Funds. Net long-term capital gains earned by a Fund, if any, will be
distributed no less frequently than once each year. Foreign exchange gains or
losses on investments and the income generated from such investments, arising
from fluctuations of exchange rates of the non-dollar denominated investments
relative to the U.S. dollar, are reported to shareholders as income in
accordance with the provisions of the Internal Revenue Code.


                                                      1997 Semiannual Report  55
<PAGE>
 
Notes to Financial Statements (Cont.)

December 31, 1997 (Unaudited)


     Income dividends and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles. These differences are primarily due to differing
treatments for such items as wash sales, foreign currency transactions, net
operating losses and capital loss carryforwards. Certain amounts have been
reclassified between undistributed net investment income, accumulated
undistributed net realized gains or losses and paid in capital to more
appropriately conform financial accounting and tax characterizations of dividend
distributions.

Multiclass Operations. Each class offered by the Trust has equal rights as to
assets and voting privileges. Income, non-class specific expenses, and realized
and unrealized capital gains and losses are allocated to each class of shares
based on the relative net assets of each class.

Federal Income Taxes. Each Fund intends to qualify as a regulated investment
company and distribute all of its taxable income and net realized gains, if
applicable, to shareholders. Accordingly, no provision for Federal income taxes
has been made.

Foreign Taxes on Dividends. Dividend income in the statement of operations is
shown net of foreign taxes withheld on dividends from foreign securities.
Foreign taxes withheld were as follows: Emerging Markets Fund - $15,422;
International Developed Fund - $34,634; Mid Cap Growth Fund - $2,380;
Renaissance Fund - $22,966; Equity Income Fund - $6,396; Value Fund - $15,793;
Small Cap Value Fund - $1,166; Enhanced Equity Fund - $1,468; and Balanced Fund
- - $1,657.

Futures and Options. Certain Funds are authorized to enter into futures
contracts and options. A Fund may use futures contracts to manage its exposure
to the stock and bond markets or change in interest rates and currency values,
or for gaining exposure to markets. The primary risks associated with the use of
futures contracts and options are imperfect correlation between the change in
market value of the securities held by a Fund and the prices of futures
contracts and options, the possibility of an illiquid market, and the inability
of the counterparty to meet the terms of the contract. Futures contracts and
purchased options are valued based upon their quoted daily settlement prices.
The premium received for a written option is recorded as an asset with an equal
liability which is marked to market based on the option's quoted daily
settlement price. Fluctuations in the value of such instruments are recorded as
unrealized appreciation (depreciation) until terminated, at which time realized
gains and losses are recognized.

Forward Currency Transactions. Certain Funds are authorized to enter into
forward foreign exchange contracts for the purpose of hedging against foreign
exchange risk arising from the Fund's investment or anticipated investment in
securities denominated in foreign currencies. A Fund may also enter into these
contracts for purposes of increasing exposure to a foreign currency or to shift
exposure to foreign currency fluctuations from one country to another. All
commitments are marked to market daily at the applicable translation rates and
any resulting unrealized gains or losses are recorded. Realized gains or losses
are recorded at the time the forward contract matures or by delivery of the
currency. Risks may arise upon entering these contracts from the potential
inability of counterparties to meet the terms of their contracts and from
unanticipated movements in the value of a foreign currency relative to the U.S.
dollar. The following foreign forward currency contracts were outstanding at
December 31, 1997 (amounts in thousands):

         For assets and liabilities other than investments in securities, net
realized and unrealized gains and losses from foreign currency transactions
arise from changes in currency exchange rates.

Repurchase Agreements. Each Fund may engage in repurchase transactions. Under
the terms of a typical repurchase agreement, the Fund takes possession of an
underlying debt obligation subject to an obligation of the seller to repurchase,
and the Fund to resell, the obligation at an agreed-upon price and time. The
market value of the collateral must be equal at all times to the total amount of
the repurchase obligations, including interest. Generally, in the event of
counterparty default, the Fund has the right to use the collateral to offset
losses incurred.

3. Fees, Expenses, and Related Party Transactions

Investment Advisory Fee. PIMCO Advisors L.P. ("PIMCO Advisors") serves as
investment advisor to the Trust, pursuant to an Investment Advisory Agreement.
PIMCO Advisors receives from the Trust a fee based on an annual percentage of
the average daily net assets of each Fund as follows: 0.57% for the Core Equity
Fund; 0.60% for the International Developed, Renaissance and Small Cap Value
Funds; 0.63% for the Mid Cap Equity Fund; 0.85% for the Emerging Markets Fund;
1.00% for the Small Cap Growth Fund; 1.25% for the Micro Cap Growth Fund; and
0.45% for all other Funds. Each of the Funds also has a sub-advisor which, under
the supervision of PIMCO Advisors, directs the investments of the Fund's assets.
Other than the sub-advisor of the Precious Metals Fund, all of the sub-advisors
are affiliates of PIMCO Advisors. The advisory fees received by PIMCO Advisors
are paid in all or in part to each of the sub-advisors in accordance with the
portfolio management agreements.

Administration Fee. PIMCO provides administrative services to the Trust for
which it receives from each Fund a monthly administrative fee based on each
share class's average daily net assets. The Administration Fee for the
Institutional Classes is charged at the annual rate of 0.50% for the Emerging
Markets and International Developed Funds and 0.25% for all other Funds. The
Administration Fee for the Retail Classes is charged at the annual rate of 0.65%
for the Emerging Markets and International Developed Funds and 0.40% for all
other Funds.

Distribution and Servicing Fees. PIMCO Funds Distributors LLC ("PFD"), formerly
PIMCO Funds Distribution Company, a wholly-owned subsidiary of PIMCO Advisors
L.P., serves as the distributor of the Trust's shares.

         The Trust is permitted to reimburse out of the Administrative Class
assets of each Fund offering Administrative Class shares, an amount up to 0.25%
on an annual basis of the average daily net assets of that class, financial
intermediaries that provide services in connection with the distribution of
shares or administration of plans or programs that use Fund shares as their
funding medium. The effective rate paid to PFD was 0.25% during the current
fiscal year.

         Pursuant to the Distribution and Servicing Plans adopted by the Retail
Classes of the Trust, the Trust compensates PFD for services provided and
expenses incurred in connection with assistance rendered in the sale of shares
and services rendered to shareholders and for maintenance of shareholder
accounts of the Retail Classes. The Trust paid PFD distribution and servicing
fees at an effective rate as set forth below (calculated as a percentage of
average daily net assets attributable to each class):

                              Distribution Fee (%)             Servicing Fee (%)

may include certain other expenses as permitted by the Trust's Multiple Class
Plan adopted pursuant to Rule 18f-3 under the Investment Company Act of 1940 and
subject to review and approval by the Trustees. The ratio of expenses to average
net assets per share class, as disclosed in Financial Highlights, may differ

certain of the funds of PIMCO Advisors Funds ("PAF"), an affiliated management
investment company, into the Trust. The reorganization occurred on January 17,
1997. In conjunction with the reorganization, the name of the Trust was changed
to "PIMCO Funds: Multi-Manager Series" from "PIMCO Funds: Equity Advisors
Series." Certain PAF funds were acquired intact and became new Funds of the
Trust. Two Funds of the Trust, the NFJ Diversified Low P/E and the Cadence Mid
Cap Growth Funds, were combined with funds acquired from PAF.

         Also, as part of the reorganization, the NFJ Diversified Low P/E Fund
and the Blairlogie International Active Fund were renamed Value Fund and
International Developed Fund, respectively, to more accurately describe the
investment style.

         Each Acquiring Fund, as listed below, acquired the assets and certain
liabilities of the Acquired Fund, also listed below, in a tax-free exchange for
shares of the Acquiring Fund, pursuant to a plan of reorganization approved by
the Acquired Fund's shareholders (amounts in thousands):
