DEAR SHAREHOLDER:
 
  The SunAmerica Balanced Assets, Blue Chip Growth, and Growth and Income
Funds each significantly outperformed its respective Lipper category average
for the six months ended March 31, 1998 on a cumulative basis. Given the
market volatility over the semi-annual period, the Funds' active yet
disciplined management--particularly through effective stock selection, sector
allocation, and focused investing within identified themes--was key to these
strong performance results. The small- and mid-cap growth arenas were
particularly hard hit by the effects of the Asian financial crises that began
to spread in the fourth quarter of 1997. Thus, as might be expected, both the
Small Company Growth and Mid-Cap Growth Funds' performance was hampered.
 
MARKET ACTIVITY
 
  The six months ending March 31, 1998 marked the turbulent end to the third
consecutive year of better than 20% gains for the Dow Jones Industrial
Average. In the fall of 1997, the problems of Southeast Asia that emerged late
summer spread to Northern Asia and exacerbated the longstanding economic
problems in Japan. The reverberations were felt quite literally around the
world. The U.S. equity markets had to digest the uncertainty of Asia,
Washington D.C.'s public relations difficulties, and earnings expectations
that were still too high. Even with increased volatility, however, the basic
underpinnings of the markets remained in place.
 
  The overall strength of the U.S. economy in spite of Asian economic
turbulence perhaps the most surprising aspect of the first quarter of 1998.
Wall Street's patience was rewarded, as the major equity indices produced
double-digit performance in the quarter even though expected growth in
corporate profits plunged to its lowest level since the 1990-91 recession.
Still, strong investor demand and heavy merger and acquisition activity
benefited the equity markets. Supported by sustained strong U.S. economic
conditions, few signs of inflation, and stable interest rates, all segments of
the stock market rallied robustly during the first calendar quarter.
 
  LARGE CAPITALIZATION STOCKS. Overall, the S&P 500 Index advanced by a solid
17.22% for the semi-annual period, and the large-cap companies led the equity
market. Short-term volatility, however, plagued the bull market throughout.
Major contributors to this volatility were the rippling effects of weakening
currencies, failing economies, and uncertain markets in Southeast Asia, which,
in turn, led to the Dow Jones' largest single one day point loss on October
27, 1997. The Far East turmoil turned equity investors to more value-oriented
stocks. As the new year began and the limited effect that the Asian problems
might have on the U.S. became clear, investors grew more confident with the
co-existence of low inflation, reasonably good GDP growth, low unemployment,
and low interest rates. The intact sound fundamentals also supported the
market's rise to record levels and a return to favor of growth-oriented
stocks.
 
  MID CAPITALIZATION STOCKS. Overall, the six months ended March 31, 1998 were
a period of significant volatility for the high growth mid-cap sector. As the
period began, mid-cap growth stocks had just experienced five months of 30%
plus performance, and stock were somewhat extended. At the same time, these
stocks came under pressure from the spreading effects of the Asian financial
crises. U.S. investors sought to lock in gains and to discount the expected
negative impact these crises would have on the earnings growth of companies
with significant exposure to Asia--especially the technology stocks. By the
 
                                       1

start of the new year, expectations for fourth quarter earnings results and
first quarter earnings estimates were low. But as the quarter progressed,
investor sentiment toward mid-cap growth stock improved.
 
  The impact of the Asian crisis was not as bad as many had feared. The
earnings growth of many companies with international exposure was sustained
despite the overseas scare and those companies that were more negatively
effected had managed lowered expectations. The result was rising prices and,
in turn, improved performance in February and March. Relative valuation levels
of these stocks had been dramatically reduced, reaching levels even cheaper
than they were in April 1997, at which point they were at seven year lows. For
the quarter as a whole, mid-cap growth stock participated with the other
segments of the stock market in a robust rally. For the six months ending
March 31, 1998, the S&P 400 MidCap Index, which often represents mid-cap
stocks, advanced by 11.94%.
 
  SMALL CAPITALIZATION STOCKS. Market activity for the small-cap sector, and
the positive and negative factors affecting these stocks, were virtually
identical to that of the mid-cap sector for the semi-annual period. At the
start of the period, small cap growth stocks had just experienced five months
during which they had outperformed both the mid-cap and large cap segments of
the market, and growth had outperformed value within the small cap sector. The
effects of the Asian financial crises, including investors' search for
perceived "safe havens" and liquidity, hit the small cap sector hard. However,
like the mid-cap sector, the first quarter of 1998 was much improved. Fears of
the impact of the Asian crisis somewhat subsided; earnings growth continued to
be strong; relative valuations approached record lows; and stable to rising
overall levels for all equity markets helped settle investors' desire for
"safe havens" and more liquid names. Sentiment surrounding small cap stocks
was boosted, and the sector rallied robustly in February and March. The
Russell 2000 Index, which often represents small stocks, produced a return of
6.37% for the six months ending March 31, 1998.
 
INVESTMENT REVIEW
 
  For the six months ending March 31, 1998, each of the SunAmerica Equity
Funds' portfolio managers focused on reducing the total number of names in
each portfolio--while staying broadly diversified--in order to enhance our
ability to monitor company activity. Each portfolio manager also continued to
use a top-down, long-term, thematic investment approach to seek high quality
growth stocks that produce consistent, double-digit earnings in any type of
economic environment. Some of these themes, or secular trends, are:
 
  * Consolidation Synergy and Asset Gathering The stocks that fit these
   themes are primarily financial services companies, including regional and
   money center banks benefiting from industry restructuring as well as
   brokerage firms benefiting from intra-industry consolidation and from the
   strong liquidity coming into the equity markets. Although the movement of
   interest rates generates risk with these stocks, these companies'
   fundamentals are solid, growth is consistent, returns on earnings and
   efficiency ratios are improving, and we believe the lines separating the
   various financial services will continue to blur. The well-publicized
   consolidations of recent months have served as icing on the cake, so to
   speak.
 
  * The Telecommunications Revolution In the larger cap Funds, our emphasis
   is on equipment companies, such as Lucent Technology and Motorola. In the
   small and mid cap Funds, our emphasis is on those companies that may
   benefit from the deregulation trend in this sector, both in the U.S. and
   internationally. For example, we see value and improving fundamentals in
   the competitive local exchange carriers which are now able to compete with
   the regional Bell operating companies.

  * Demand for Technology and The Burgeoning Internet Technology stocks are
   still comparatively volatile due to the softness in Asia, and thus the
   Funds are taking a conservative position in this sector. In the larger cap
   Funds, our emphasis is on market leaders, such as Intel, Microsoft, Dell,
   and Compaq. In the smaller cap Funds, we are invested in select technology
   stocks whose revenue streams are derived largely within the U.S. Those
   companies providing ancillary services to the growing Internet community,
   such as billing, outsourcing, and security, may also be attractive.
 
  * Graying of America The larger cap Funds are focusing on the large drug
   companies within the health care sector, where we continue to see
   consistent double-digit earnings coming from new pharmaceutical products
   and unit by volume. Health care device companies seem attractive in the
   small cap sector.
 
  * Shift to a Service-Based Economy Several consumer-oriented companies have
   made great productivity enhancements, overcoming their overstorage
   problems of the last several years. The result is better returns on
   earnings and accelerating growth rates. Certain specialty vendors with
   innovative strategies, such as Home Depot and the Gap, remain attractively
   valued to the large cap Funds. Certain cruise lines, educational services
   companies, and companies addressing the Year 2000 Problem may be
   attractive within the small cap sector.
 
  * Reliance on Natural Resources The larger cap Funds added to their energy
   positions over the period, as we believe underlying fundamentals are
   improving, demand for oil and gas has the potential to increase from
   current low levels, and industry consolidation is resulting in better
   management and generation of cash flow. The smaller cap Funds reduced
   their holdings here, as the smaller oil service and equipment companies
   were impacted by the crisis in Asia more than their larger brethren.
 
  THE BALANCED ASSETS FUND ranked in the top decile of its Lipper category
average for the six months ending March 31, 1998. Equity securities comprised
68.6% of this portfolio's assets on March 31st; fixed income securities
comprised 30.2%, most of which was in U.S. Treasuries, which did particularly
well as a "flight to quality" following the Asian crisis benefited these
securities. Holding 104 names at the end of the period, the Fund's largest
allocations were to financial services, banks, pharmaceuticals and
telecommunications.
 
  THE BLUE CHIP GROWTH FUND held 85 names as of March 31, 1998, with its
largest concentrations in financial services, banks, telecommunications, and
pharmaceuticals. It held 2.2% in cash at period end. The Fund outperformed its
Lipper category average for the six months ending March 31, 1998.
 
  THE MID-CAP GROWTH FUND stayed true to its long-standing growth-oriented
investment style through both the difficult fourth quarter and the more
positive first quarter. The Fund outperformed its Lipper category average in
the rally month of March. However, for the six months ending March 31, 1998,
the Fund underperformed. As of March 31, the Fund held 102 names, with its
largest allocations to the software, telecommunications, energy services, and
broadcasting & media sectors. This Fund is currently undergoing a transition,
under new management by portfolio managers from both the large and small
capitalization teams.
 
  THE SMALL COMPANY GROWTH FUND'S relative performance was hampered by its
growth-oriented investment style during the first half of the period and
likewise helped by it in the second half. Following the
 
                                       3

jmarket correction in October, the Fund sold a number of its holdings with
Asian exposure and significantly increased its allocation to cash. Slowly, we
began re-allocating assets, primarily to domestically-oriented software,
telecommunications, broadcast & media, business services, and bank stocks.
However, the Fund did not participate fully in the market's first quarter
relief rally. As of March 1, 1998, the Fund is under the management of Donna
Calder. By the end of the period, she reduced the number of holdings to 125
and decreased the Fund's cash holding to 4.9% of portfolio assets.
 
  THE GROWTH AND INCOME FUND is under new management within the large
capitalization team. The Fund's objective and strategy remains the same,
however, we intend to reduce the number of names, which at the end of the
period stood at 135. We also intend to lower the Fund's exposure to REITs and
increase its exposure to the financial services and energy sectors. For the
six months ending March 31, 1998, the Fund outperformed its Lipper category
average.
 
MANAGER OUTLOOK
 
  Our outlook for the equity markets remains very positive for several
reasons. First, we remain in a moderate growth, low inflationary, low interest
rate environment. Second, increased competition from Asian imports will most
likely force corporate America to be cognizant of costs and margin erosion,
and thus we believe the earnings on an operating basis will be between 5%-7%
in 1998--still quite strong given that we are in the 8th year of expansion. We
may even see a return to double-digit profits in 1999, as corporations benefit
from the formation of EMU, a slightly most positive situation in Asia, and
forced Year 2000 technology spending. Third, liquidity, which is currently
driving the market, remains strong. It has, however, taken on new forms. Not
only is the individual investor continuing to put money into the market at a
rapid pace, but corporations also are flush with cash, which we see being put
to use in the form of stock repurchases and increased merger and acquisition
activity. International investors are also increasing their exposure to U.S.
markets.
 
  On the other hand, a speculative fear of action by the Federal Reserve Board
is likely to hang over the markets; we expect volatility to increase; another
shoe dropping from the Asian situation may yet occur; and we would not be
surprised to see a 5%-7% market correction--though short-lived--in the near
future. Still a pause may be welcome, as longer-term fundamentals suggest that
the bull market is far from over. We believe that the equity markets will end
1998 above their current lofty levels.
 
  We value your ongoing support of the SunAmerica Equity Funds and look
forward to serving your investment needs in the years ahead with pro-active
management and capital appreciation consistent with each Fund's objective.

  SunAmerica Mid-Cap Growth Fund ("Mid-Cap Growth Fund"), SunAmerica Small
  Company Growth Fund ("Small Company Growth Fund"), and SunAmerica Growth
  and Income Fund ("Growth and Income Fund"). The Funds are considered to be
  separate entities for financial and tax reporting purposes. The investment
  objective for each of the Funds is as follows:
 
  Balanced Assets seeks to conserve principal by maintaining at all times a
  balanced portfolio of stocks and bonds.
  Blue Chip Growth seeks capital appreciation by investing primarily in
  equity securities of companies with large market capitalizations.
  Mid-Cap Growth seeks capital appreciation by investing primarily in equity
  securities of medium-sized companies.
  Small Company Growth seeks capital appreciation by investing primarily in
  equity securities of small capitalization growth companies.
  Growth and Income seeks capital appreciation and current income by
  investing primarily in common stocks.
 
  Each Fund currently offers Class A and Class B shares. Small Company Growth
  Fund and Growth and Income Fund also offer Class C shares and Balanced
  Assets Fund and Small Company Growth Fund offer Class Z shares, exclusively
  for sale to employees participating in the SunAmerica profit sharing and
  retirement plan. Class A shares are offered at net asset value per share
  plus an initial sales charge. Class B and Class C shares are offered
  without an initial sales charge, although a declining contingent deferred
  sales charge may be imposed on redemptions made within six years of
  purchase of Class B shares and within one year of purchase of Class C
  shares. Class Z shares are offered at net asset value. Any purchases of
  Class A shares in excess of $1,000,000 will be subject to a contingent
  deferred sales charge on redemptions made within one year of purchase.
  Class B shares of each Fund will convert automatically to Class A shares on
  the first business day of the month after seven years from the issuance of
  such Class B shares and at such time will be subject to the lower
  distribution fee applicable to Class A shares. Each class of shares bears
  the same voting, dividend, liquidation and other rights and conditions.
  Class A, Class B and Class C shares each make distribution and account
  maintenance and service fee payments under the distribution plans pursuant
  to Rule 12b-1 under the Investment Company Act of 1940 (the "1940 Act"),
  except that Class B and Class C shares are subject to higher distribution
  fee rates. There are no distribution or service fee payments applicable to
  Class Z.

Note 2. Significant Accounting Policies
 
  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 these estimates. The
  following is a summary of the significant accounting policies followed by
  the Funds in the preparation of their financial statements:
 
  SECURITY VALUATIONS: Securities that are actively traded in the over-the-
  counter market, including listed securities for which the primary market is
  believed by the Adviser to be over-the-counter, are valued at the quoted
  bid price provided by principal market makers. Securities listed on the New
  York Stock Exchange ("NYSE") or other national securities exchanges, are
  valued on the basis of the last sale price on the exchange on which they
  are primarily traded. If there is no sale on that day, then securities are
  valued at the closing bid price on the NYSE or other primary exchange for
  that day. However, if the last sale price on the NYSE is different than the
  last sale price on any other exchange, the NYSE price is used. Securities
  that are traded on foreign exchanges are ordinarily valued at the last
  quoted sales price available before the time when the assets are valued. If
  a security's price is available from more than one foreign exchange, a Fund
  uses the exchange that is the primary market for the security. Options
  traded on national securities exchanges are valued as of the close of the
  exchange on which they are traded. Futures and options traded on
  commodities exchanges are valued at their last sale price as of the close
  of such exchange. The Funds may make use of a pricing service in the
  determination of their net asset values. Securities for which market
  quotations are not readily available and other assets are valued at fair
  value as determined pursuant to procedures adopted in good faith by the
  Trustees. Short-term investments which mature in less than 60 days are
  valued at amortized cost, if their original maturity was 60 days or less,
  or by amortizing their value on the 61st day prior to maturity, if their
  original term to maturity exceeded 60 days.
 
  REPURCHASE AGREEMENTS: The Funds, along with other affiliated registered
  investment companies, transfer uninvested cash balances into a single joint
  account, the daily aggregate balance of which is invested in one or more
  repurchase agreements collateralized by U.S. Treasury or federal agency
  obligations. The Funds' custodian takes possession of the collateral
  pledged for investments in repurchase agreements. The underlying collateral
  is valued daily on a mark to market basis to ensure that the value,
  including accrued interest, is at least equal to the repurchase price. In
  the event of default of the obligation to repurchase, a Fund has the right
  to liquidate the collateral and apply the proceeds in satisfaction of the
  obligation. If the seller defaults and the value of the collateral declines
  or if bankruptcy proceedings are commenced with respect to the seller of
  the security, realization of the collateral by the Fund may be delayed or
  limited.
 
  As of March 31, 1998, Balanced Assets Fund, Blue Chip Growth Fund, Mid-Cap
  Growth Fund, Small Company Growth Fund and Growth and Income Fund had a
  0.9%, 2.7%, 1.1%, 13.1%, and 4.0% undivided interest, respectively, which
  represented $890,000, $2,624,000, $1,037,000, $12,775,000, and $3,892,000,
  respectively, in principal amount in a joint repurchase agreement with
  PaineWebber Group, Inc. As of such date, the repurchase agreement in the
  joint account and the collateral therefor were as follows:

 NOTES TO FINANCIAL STATEMENTS -- March 31, 1998 (unaudited) -- (continued)

  PaineWebber Group, Inc. Repurchase Agreement 5.75% dated 3/31/98, in the
  principal amount of $97,641,000 repurchase price $97,656,595 due 4/01/98
  collateralized by $50,000,000 U.S. Treasury Note 6.375% due 1/15/99, and
  $47,885,000 U.S. Treasury Note 6.25% due 6/30/98; approximate aggregate
  value $99,682,537.
 
  SECURITIES TRANSACTIONS, INVESTMENT INCOME, EXPENSES, DIVIDENDS AND
  DISTRIBUTIONS TO SHAREHOLDERS: As customary in the mutual fund industry,
  securities transactions are recorded on a trade date basis. Realized gains
  and losses on sales of investments are calculated on the identified cost
  basis. Interest income is recorded on the accrual basis; dividend income is
  recorded on the ex-dividend date. Funds investing in foreign securities may
  be subject to taxes imposed by countries in which they invest. Such taxes
  are generally based on either income or gains earned or repatriated. The
  Equity Funds, except for the Growth and Income Fund, do not amortize
  premiums or accrete discounts except for original issue discounts and on
  interest only securities for which amortization is required for federal
  income tax purposes.
 
  Net investment income, other than class specific expenses and realized and
  unrealized gains and losses, is allocated daily to each class of shares
  based upon the relative net asset value of outstanding shares (or the value
  of the dividend-eligible shares, as appropriate) of each class of shares at
  the beginning of the day (after adjusting for the current capital shares
  activity of the respective class).
 
  Expenses common to all Funds, not directly related to individual Funds, are
  allocated among the Equity Funds based upon their relative net asset value
  or other appropriate methods.
 
  The Funds issue and redeem their shares, invest in securities and
  distribute dividends from net investment income and net realized gains
  which are paid in cash or are reinvested at the discretion of shareholders.
  These activities are reported in the Statement of Changes in Net Assets.
 
  Dividends from net investment income, if any, are paid semiannually, except
  for Balanced Assets Fund and Growth and Income Fund, which pay quarterly.
  Capital gain distributions, if any, are paid at least annually.
 
  The Funds record dividends and distributions to their shareholders on the
  ex-dividend date. The amount of dividends and distributions from net
  investment income and net realized capital gains are determined and
  presented in accordance with federal income tax regulations, which may
  differ from generally accepted accounting principles. These "book/tax"
  differences are either considered temporary or permanent in nature. To the
  extent these differences are permanent in nature, such amounts are
  reclassified within the capital accounts based on their federal tax-basis
  treatment; temporary differences do not require reclassification. Net
  investment income/loss, net realized gain/loss, and net assets were not
  affected.

  For the year ended September 30, 1997, the following reclassifications
  arising from book/tax differences were primarily the result of

  FOREIGN CURRENCY TRANSLATION: The books and records of the Funds are
  maintained in U.S. dollars. Assets and liabilities denominated in foreign
  currencies are translated into U.S. dollars at the mean of the quoted bid
  and asked prices of such currencies against the U.S. dollar.
 
  The Funds do not isolate that portion of the results of operations arising
  as a result of changes in the foreign exchange rates from the changes in
  the market prices of securities held at fiscal year-end. Similarly, the
  Funds do not isolate the effect of changes in foreign exchange rates from
  the changes in the market prices of portfolio securities sold during the
  year.
 
  Realized foreign exchange gains and losses on other assets and liabilities
  and change in unrealized foreign exchange gains and losses on other assets
  and liabilities include foreign exchange gains and losses from currency
  gains or losses between the trade and settlement dates of securities
  transactions, the difference between the amounts of interest, dividends and
  foreign withholding taxes recorded on the Fund's books and the U.S. dollar
  equivalent amounts actually received or paid and changes in the unrealized
  foreign exchange gains and losses relating to other assets and liabilities
  arising as a result of changes in the exchange rate.
 
  ORGANIZATIONAL EXPENSES: Costs incurred by SAAMCo in connection with the
  organization of Growth and Income Fund amounted to $1,383. These costs are
  being amortized on a straight line basis by the Fund over a period not to
  exceed 60 months from the date the Fund commenced operations.
 
Note 3. Investment Advisory and Management Agreement, Distribution Agreement
      and Service Agreement
 
  The Trust, on behalf of each Fund, has an Investment Advisory and
  Management Agreement (the "Agreement") with SAAMCo. Under the Agreement,
  SAAMCo provides continuous supervision of a Fund's portfolio and
  administers its corporate affairs, subject to general review by the
  Trustees. In connection therewith, SAAMCo furnishes the Funds with office
  facilities, maintains certain of the Funds' books and records, and pays the
  salaries and expenses of all personnel, including officers of the Funds who
  are employees of SAAMCo and its affiliates. The investment advisory and
  management fee to SAAMCo with respect to each Fund is computed daily and
  payable monthly, at an annual rate of .75% of a Fund's average daily net
  assets up to $350 million, .70% of the next $350 million, and .65%
  thereafter. For the six months ended March 31, 1998, SAAMCo earned fees in
  the amounts stated on the Statement of Operations.

  The Trust, on behalf of each Fund, has a Distribution Agreement with
  SunAmerica Capital Services, Inc. ("SACS"), an indirect wholly-owned
  subsidiary of SunAmerica Inc. Each Fund has adopted a Distribution Plan
  (the "Plan") in accordance with the provisions of Rule 12b-1 under the 1940
  Act. Rule 12b-1 permits an investment company directly or indirectly to pay
  expenses associated with the distribution of its shares ("distribution
  expenses") in accordance with a plan adopted by the investment company's
  board of trustees and approved by its shareholders. Pursuant to such rule,
  the Trustees and the shareholders of each class of shares of each Fund have
  adopted Distribution Plans hereinafter referred to as the "Class A Plan",
  "Class B Plan" and "Class C Plan". In adopting the Distribution Plans, the
  Trustees determined that there was a reasonable likelihood that each such
  Plan would benefit the Trust and the shareholders of the respective class.
  The sales charge and distribution fees of a particular class will not be
  used to subsidize the sale of shares of any other class.
 
  Under the Class A Plan, Class B Plan and Class C Plan, the Distributor
  receives payments from a Fund at an annual rate of up to 0.10%, 0.75% and
  0.75%, respectively, of average daily net assets of such Fund's Class to
  compensate the Distributor and certain securities firms for providing sales
  and promotional activities for distributing that class of shares. The
  distribution costs for which the Distributor may be reimbursed out of such
  distribution fees include fees paid to broker-dealers that have sold Fund
  shares, commissions and other expenses such as those incurred for sales
  literature, prospectus printing and distribution and compensation to
  wholesalers. It is possible that in any given year the amount paid to the
  Distributor under each Class' Plan may exceed the Distributor's
  distribution costs as described above. The Distribution Plans provide that
  each class of shares of each Fund may also pay the Distributor an account
  maintenance and service fee up to an annual rate of 0.25% of the aggregate
  average daily net assets of such class of shares for payments to broker-
  dealers for providing continuing account maintenance. Accordingly, for the
  six months ended March 31, 1998, SACS received fees (see Statement of
  Operations) based upon the aforementioned rates.
 
  SACS receives sales charges on each Fund's Class A shares, portions of
  which are reallowed to affiliated broker-dealers and non-affiliated broker-
  dealers. SACS also receives the proceeds of contingent deferred sales
  charges paid by investors in connection with certain redemptions of each
  Fund's Class B and Class C shares. SACS has advised the Funds that for the
  six months ended March 31, 1998 the proceeds received from sales (and paid
  out to affiliated and non-affiliated broker-dealers) and redemptions are as
  follows:

Note 7. Commitments and Contingencies
 
  The SunAmerica family of mutual funds may borrow up to $75,000,000 under an
  uncommitted line of credit with State Street Bank and Trust Company, the

  Plan (the "Retirement Plan") effective January 1, 1993 for the unaffiliated
  Trustees. The Retirement Plan provides generally that if an unaffiliated
  Trustee who has at least 10 years of consecutive service as a Disinterested
  Trustee of any of the SunAmerica mutual funds (an "Eligible Trustee")
  retires after reaching age 60 but before age 70 or dies while a Trustee,
  such person will be eligible to receive a retirement or death benefit from
  each SunAmerica mutual fund with respect to which he or she is an Eligible
  Trustee. As of each birthday, prior to the 70th birthday, but in no event
  for a period greater than 10 years, each Eligible Trustee will be credited
  with an amount equal to 50% of his or her regular fees (excluding committee
  fees) for services as a Disinterested Trustee of each SunAmerica mutual
  fund for the calendar year in which such birthday
