 1. ORGANIZATION AND BUSINESS
 
     Keynote Series Account ("Keynote") is a separate investment account
established on December 16, 1987 by The Mutual Life Insurance Company of New
York ("MONY") under the laws of the State of New York.
 
     Keynote operates as a unit investment trust under the Investment Company
Act of 1940, as amended (the "1940 Act"). Keynote holds assets that are
segregated from all of MONY's other assets and, at present, is used as an
investment vehicle under certain tax-deferred annuity contracts issued by MONY
to fund retirement plans maintained by certain not-for-profit and other
organizations ("Group Plans"). MONY is the legal holder of the assets in
Keynote.
 
     There are currently seven subaccounts within Keynote which are available to
contractholders of Group Plans. Six of the subaccounts invest in a corresponding
portfolio of Diversified Investors Portfolios (the "Portfolios") and the seventh
subaccount invests in Calvert Social Balanced Portfolio (formerly, Calvert
Responsibly Invested Balanced Portfolio), a series of Calvert Variable Series,
Inc. (formerly, Acacia Capital Corporation), ("Calvert" and collectively, the
"Funds"). The respective financial statements of the Funds are contained
elsewhere in this report.
 
     At June 30, 1998, each of the subaccounts' investment in the corresponding
Portfolios was as follows:

</TABLE>
 
 2. SIGNIFICANT ACCOUNTING POLICIES
 
  A. Investments:
 
     The investment by Keynote in the Portfolios reflects Keynote's
proportionate interest in the net assets of each of the Portfolios. The
investment in shares of Calvert is stated at net asset value. The Keynote
subaccount which invests in Calvert records its security transactions at the
prior day's ending net asset value per share. Valuation of the securities held
in each of the Portfolios is discussed in Note 2A of the Portfolios' Notes to
Financial Statements which are included elsewhere in this report. A description
of the portfolio valuation for Calvert can be found in Note A of its financial
statements contained elsewhere in this report.
 
  B. Investment Income:
 
          Each Keynote subaccount earns income, net of expenses, daily on its
     investment in the corresponding Portfolio. All of the net investment income
     and realized and unrealized gains and losses from the security transactions
     of the corresponding Portfolios are allocated pro rata among the investors
     at the time of such determination. Dividend income is recorded on the
     ex-dividend date. Realized gains and losses from investments sold are
     determined on the basis of identified cost.
 
  C. Federal Income Taxes:
 
     The operations of Keynote form a part of, and are taxed with, the
operations of MONY. MONY does not expect, based upon current tax law, to incur
any income tax upon the earnings or realized capital gains

  C. Federal Income Taxes (Continued):

attributed to Keynote. Based upon this expectation, no charges are currently
being deducted from Keynote for federal income tax purposes.
 
  D. Other:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 3. FEES AND TRANSACTIONS WITH AFFILIATES
 
     Daily charges to Keynote for mortality and expense risks assumed by MONY
are computed at an annual rate of 0.90%; however, MONY reserves the right to
charge maximum fees of 1.25% upon notice.
 
     MONY has voluntarily undertaken to waive expenses of the Money Market
Subaccount, to the extent necessary, to limit all expenses (other than mortality
and expense risk charges) to 0.10% of average net assets. MONY reserves the
right to raise this limit upon notice.
 
 4. GROUP PLAN ASSUMPTIONS
 
     On December 31, 1993, MONY entered into an agreement with AUSA Life
Insurance Company, Inc. ("AUSA"), a wholly owned subsidiary of AEGON, USA,
pursuant to which the Group Plans may be transferred through assumption
reinsurance to AUSA. Subject to receipt of any necessary state insurance
department approvals and authorizations, each Group Plan contractholder receives
materials relating to this assumption. The assumption reinsurance of any Group
Plan to AUSA will result in the transfer of the applicable assets out of Keynote
and into a corresponding separate account of AUSA. Assets transferred to AUSA
pursuant to this assumption reinsurance transaction for the year ended December
31, 1997, were as follows:

                              SECOND QUARTER 1998
 
                               ECONOMIC OVERVIEW
 
     After recording a 5.4% growth rate in the first quarter, it appears as
though economic activity is subsiding. The slowdown is largely attributable to a
decrease in inventory accumulation and deceleration in the manufacturing sector
due to export weakness. Export weakness is primarily a result of a strong dollar
relative to other major currencies and the Asian meltdown.
 
     Despite early indications of a potential economic retracing, the consumer
remains upbeat. The Consumer Confidence Index remains at secular highs with a
strong labor market providing the major underpinning.
 
     The inflation picture remains in check, with the Consumer, and Producer
Price Indices under control. The question remains whether the tightness in the
labor market will ultimately result in businesses raising prices. Other
prevalent counter-forces are keeping this in question.
 
     The Federal Reserve has maintained its neutral policy, and kept the Fed
Funds Rate, at 5.5%. We do not anticipate a change in policy unless economic
fundamentals deteriorate.
 
                               FINANCIAL MARKETS
 
     During the second quarter, bonds posted positive results, while stocks were
mixed.
 
     Large capitalization stocks, as measured by the S&P 500 Index, returned
3.3% for the quarter, while the small capitalization stocks, as measured by the
Russell 2000 Index, continued their relative under-performance, falling 4.7%.
Over the past year, the S&P 500 outpaced the Russell 2000 by 13.8%. Small and
mid-cap stocks have fallen to their lowest levels in almost eight years relative
to the S&P 500. The equity advance has been focused on large cap stocks, a
pattern that is typical in a maturing bull market.
 
     There was also a divergence of performance among large cap equity styles.
Growth stocks (Russell 1000 Growth Index) returned 4.5%. Value stocks, (Russell
1000 Value Index) returned 0.5%.
 
     The growth sector was helped by technology, health care and consumer
discretionary stocks, while the value sector was hurt by the utility, industrial
and basic industry sectors.
 
     International equity stocks as measured by the MSCI GDP EAFE Index returned
3.99% for the quarter. This result was buoyed by strong returns among European
bourses, with soaring economies in Germany and France. Troubled Asian markets
continued to post negative returns.
 
     The bond market, as measured by the Lehman Brothers Government/Corporate
Index, returned 2.6% during the second quarter. The bond market was boosted by
US Treasury performance, as the interest rate on the 30-year US Treasury fell to
all time lows and closed at 5.62%.
 
     Corporate bonds under-performed their Government counterparts, as troubles
in Asia and Russia, and decelerating corporate earnings detracted from returns.
 
                                    OUTLOOK
 
     Our outlook with respect to the economy and financial markets has not
changed from the first quarter. We believe that economic growth will slow over
the next few quarters, with a continued widening in the trade deficit, and a
slowdown in job and income growth. We continue to believe that the Federal
Reserve will leave interest rates unchanged for the foreseeable future.
 
     As a result, we are reducing the top-end of the expected interest rate
range on the 30-year Treasury to 6.15% from 6.35%, and keeping the low end at
5.5%.
 
     Stock valuation levels remain high relative to the projected earnings
growth rates. Analysts continue to reduce earnings estimates. As a result, we
continue to remain cautious on stocks. We continue to favor the large
capitalization stocks over small capitalization stocks; value over growth.

                     SECOND QUARTER 1998 FUND COMMENTARIES
 
                                  MONEY MARKET
 
     The yield curve flattened significantly in the second quarter, particularly
in the term area two years and longer. Interest rates on the long bond dropped
30 basis at the end of the second quarter. The short end also rallied, albeit
modestly, as evidenced by the three month T-bill's four basis point drop in
yield from 5.13% at 3/31/98 to 5.09% at quarter end. With the Fed having
formally adopted a tightening bias during the second quarter, expectations are
that the Fed's next move will be an upward adjustment in the Fed Funds rate.
However, market sentiment on the timing of such a move is that the Fed is at
least several months away from carrying out a tightening The average maturity of
the portfolio will be extended selectively to capitalize on opportunities where
the portfolio will be rewarded for duration extention. Such opportunities have
become increasingly available toward the end of the second quarter as the yield
curve for short-term securities retreated from its long prevalent inverted
shape.
 
     The portfolio continues to be invested in high quality short-term
instruments, principally commerical paper. Our investment strategy is to
emphasize purchases of 30-90 day maturities to provide flexibility to respond to
any changes in the market place without sacrificing current income.
 
                               HIGH QUALITY BOND
 
     Several factors contributed to the portfolio's favorable performance during
the second quarter. First, the income component of total return offset the lower
prices resulting from spread widening. Second, the duration of the account was
slightly longer than that of the index. Since Treasury yields trended lower,
this resulted in slightly better performance for assets with longer maturities.
 
     The "flight to quality" theme was recurrent throughout the period as news
regarding economic problems in Asia caused investors to periodically seek the
safety of US Treasuries. The combination of earnings uncertainty and increased
issuance caused spreads to widen up to 10 basis points in the corporate sector.
We were modestly active in this sector, purchasing a five year Ford Global note
at +54 basis points versus the comparable Treasury. We lengthened duration and
added yield by swapping into an Associates Corp. note with a longer maturity.
 
     In general, spreads on asset backed securities widened modestly. We
purchased a Sears credit card securitization at a spread of 45 basis points
versus the comparable Treasury. We added Navistar and Compass Bank to the
portfolio at a spread of +43 and +53 basis points, respectively.
 
     We continue to find value in selected agency, domestic corporate, and asset
backed sectors.
 
                            INTERMEDIATE GOVERNMENT
 
     US Treasuries were the best performing sector in the bond market last
quarter, as international investors pulled capital from the troubled and
volatile Asian markets and moved to the safe haven of government securities.
Longer maturity bonds were favored, resulting in a very flat yield curve. By
quarter-end there was only a marginal increase in return for securities maturing
further in the future. The bond markets are now priced so as to expect no
Federal Reserve action to either raise or lower interest rates in the
foreseeable future.
 
     This neutral outlook contrasts somewhat with the minutes of the May meeting
of the Fed, which reflected a "close call" on the decision to raise rates in
order to cool off a steaming domestic economy and nip an increase in inflation.
We see the economy cooling somewhat over the summer, especially in export
businesses, before picking up again in the fall. The portfolio remains
positioned defensively, slightly short of target duration, both in deference to
the Fed bias, as well as the absence of incremental yield in longer maturity
securities. It also holds a small position in Inflation Protected Treasury
securities.
 
                                        9
<PAGE>   14
 
                           GOVERNMENT/CORPORATE BOND
 
     The significant event in the bond market during the second quarter was the
re-emergence of Asian financial turbulence and its effect of driving global
investors to the safety of US Treasury securities. The focus this time was on
Japan, caught in a seeming never-ending recession and facing an attach on the
once almighty yen. The risk is that their economic downturn would continue to
spread, letting the air out of the worldwide economic growth. As a result, bond
prices rose and interest rates, especially for longer maturity Treasury
securities fell near recent record lows.
 
     With a flight to quality of US Treasuries, virtually all other sectors of
the bond market lagged in performance. Corporate spreads -- incremental risk
premium paid to holders of corporate bonds -- increased by 10-15 basis points to
the widest levels in three years. As a result, corporate securities in the
portfolio under-performed.
 
     Our belief is that, while slowed slightly, the US economy will not be
seriously impaired by overseas weakness. Corporate profits on the whole should
remain strong and longer-term the bias is towards somewhat higher interest
rates. Thus the portfolio remains over-weighted in corporate bonds, with a
slightly shorter than benchmark duration.
 
                                HIGH YIELD BOND
 
     Second quarter market dynamics reflected a shift from the trends of the
prior twelve months. Elevated equity and treasury market volatility, plus a
heavy new issue calendar, led to spread widening in the high yield market.
BB-rated issues outperformed single B-paper during the period as new issuance
was heavily concentrated among B's. Returns consisted entirely of income during
the quarter, as prices eroded slightly with the rise in market yields.
Nevertheless, high yield credit quality remained excellent, and shows no sign of
deterioration. The second quarter can thus be best described as one in which
market technicals overwhelmed otherwise positive fundamentals.
 
     We remain constructive on the outlook for the US economy. We continue to
believe that Asian economic weakness will keep global commodity prices low and
US economic activity at a moderate, sustainable level. Consequently,
inflationary pressures should remain subdued. The portfolio remains biased
toward single B issues with the balance in BB's. Core positions were established
in Aurora Foods (B1), a producer of branded foods such as Log Cabin Syrup and
Duncan Hines Cakes; P&L Coal (BA3), the nation's largest operation of coal
mines, and Octel (B+), the world's largest manufacturer of lead additives for
gasoline. We trimmed our already below market weightings in energy and autos,
given the state of energy prices and the GM strike, respectively.
 
                                    BALANCED
 
     The equity market continued its strong gains in the second quarter.
However, investors steered away from stocks that could be vulnerable to weaker
growth in Asia. With lower interest rates and oil prices buoying consumer
spending, domestic-oriented cyclicals such as autos and retailers were strong
performers, along with traditional growth sectors such as technology and health
care. There are building signs that US growth is about to slow, so over the
balance of the year there could continue to be downward pressure on earnings
estimates. The good news is that in such an environment, Federal Reserve policy
would be expected to remain in an accommodative posture, which historically has
been favorable for the financial markets.
 
     The best performing stocks in the portfolio all took significant corporate
actions consistent with our restructuring theme. These included News
Corporation, Hoechst, and Philips Electronics. On the downside, the concerns
about building economic weakness negatively impacted Case and IMC Global.
 
     The portfolio is currently allocated near its benchmark of 60% equity and
40% fixed income. The allocation balances the positives from accommodative Fed
policy with the negative trend in general earnings expectations.

                                 EQUITY INCOME
 
     The major investment event of the second quarter was the resurgence of the
problems in Asia, this time centered on Japan. As happened last fall, the dollar
strengthened, projections for US economic growth and inflation were lowered and
US economic growth and inflation were lowered and US interest rates rose as
foreign investors sought a safe haven.
 
     Investors also sought the safety in large cap growth stocks and in
technology stocks, many of which the portfolio cannot own due to little or no
dividend yield. To compound the problem, cyclicals, energy and telephone
stocks -- all high yield, value names -- sold off, creating a very difficult
quarter for income oriented funds.
 
     The current outlook is for slowing economic growth. While commodity
inflation is very low, wage costs are beginning to rise. It is not easy to pass
on cost increases today and profit margins are coming under pressure creating
earnings uncertainty.
 
     The market environment is thus becoming more risky with valuations high and
earnings growth questionable. Portfolio strategy emphasizes defensive sectors
which have lagged the market as investors moved into growth stocks.
International oils, natural gas, electric and telephone utilities, retailers and
selected financial and health care names are the main emphasis.
 
                                  EQUITY VALUE
 
     The second quarter was difficult from a performance standpoint for the
large cap value style. The market in effect became two-tiered, with large cap
growth significantly outperforming all other stocks and driving the S&P 500
performance in the process. The best performing sector was technology, followed
by consumer cyclicals and health care. The worst performing sectors were
transportation, communications and basic materials.
 
     The most attractively valued sectors in the market are cyclically oriented
and economically sensitive ones such as basic materials, capital goods, energy
and consumer cyclicals. The first three sectors have been impacted by the
Pacific Rim/Japanese economic crisis, and at current levels, there would appear
to be little downside left. Our portfolio is heavily invested in these areas
based on the valuations and fundamentals. Purchases during the quarter include
3M, Dana Corp. and General Mills. Significant sales included Chrysler and Sears.
We have also increased our exposure in communications with the purchase of AT&T.
 
     The financial sector markedly impacted performance and we added Banc One to
our holdings. Utilities contributed and health care was also positive, but
lagged a bit because of underweighting. Energy and capital goods were the
biggest detractors. We are overweighted in both because of attractive valuations
and strong fundamentals, but the growth stocks within these sectors were the
best performers.
 
     Going forward, our portfolio would clearly benefit from ongoing economic
strength and a rebound in commodity prices. We will continue to avoid the
overvalued sectors of the market and focus on areas where the fundamentals and
valuations are more solid.
 
                                GROWTH & INCOME
 
     During the second quarter, the portfolio was well positioned to benefit
from the large cap equity sector's general out-performance. The portfolio was
over-weighted in all three of the top performing sectors -- consumer cyclicals,
technology and health care. Perhaps more importantly, the portfolio benefited
from good stock selection, particularly in the technology and healthcare
sectors.
 
     Significant performance came from the technology sector with strong returns
from Microsoft and BMC Software. The portfolio's low exposure to the
semiconductor and related equipment industries continued to be the correct
decision as these stocks under-performed.
 
                                       11
<PAGE>   16
 
     The only significant negative impact on performance came in the consumer
services industry, where Cendant Corp. shares fell sharply after the company
announced an accounting problem in one of its divisions.
 
     We added stocks in the banking and the medical distribution industries, as
well as adding exposure to the networking industry. We further reduced holdings
from the already under-weighted energy sector.
 
     Our strategy continues to focus on earnings growth from domestic sources,
such as retail, computer software and new drug introductions. We remain cautious
of exposure to Asian economies and to earnings derived from commodity cyclicals,
which are demonstrating little pricing power in this low-inflation economy.
 
                                 EQUITY GROWTH
 
     The portfolio turned in solid results for the second quarter aided by
strong performance from the multinational consumer, and health care sectors.
Stock selection in the technology sector also added significant value to the
portfolio.
 
     Select technology stocks -- America Online (+54%), Cisco (+35%) and Nokia
(+35%) all contributed to performance. The portfolio also purchased Hewlett
Packard and made an additional commitment to Intel.
 
     Health care was also a major positive, with significant contributions to
performance by Warner Lambert, and Eli Lilly, which rebounded after a
disappointing Evista launch. We remain committed to our overweight in health
care but continue to rotate into names that have either a better pipeline,
superior positioning, or more attractive relative valuations. We have been
buying American Home Products/Monsanto in advance of the merger, as well as
Amgen.
 
     To fund purchases, the portfolio trimmed Eli Lilly and Smithkline Beecham.
Phillip Morris was also sold due to the continued uncertainty over litigation
and the proposed settlement. Cendant and Pioneer Hi-Bred were sold on the
announcement that they would restate earnings due to accounting irregularities,
and on valuation, respectively.
 
     Our outlook remains cautious for the market as a whole, although more
positive for our style of high quality growth management. We continue to believe
that earnings in the US are slowing driven by ongoing margin pressure and the
Asia crisis.
 
                                 SPECIAL EQUITY
 
     In the second quarter, small companies continued to under-perform large
companies. The culprit remains a flight to safety by investors, worried about
financial disarray in Asia and Russia, and the direction of interest rates.
 
     While generally a difficult quarter, performance bright spots could be
found in the service, consumer, telecommunications and financial sectors.
 
     Stocks which added value include Nokia, Metzler Group, Chancellor Media,
Centennial Cellular, Fingerhut, Duane Reade, and several takeover stocks
including PMT Service, NSS Bancorp and Xtra Corp. Specific stocks which
detracted from performance include DT Industries, Amplicon, and Cendant. Stocks
impacted by Asian weakness faired poorly as well.
 
     Our long-term outlook remains positive for the small cap sector. However,
we believe that the balance of the year is likely to be volatile. The portfolio
continues to focus on growth stocks with domestic exposure and earnings
predictability. On the value side, we expect increased investment attractively
priced, faster growing small cap companies.
 
                                       12
<PAGE>   17
 
                               AGGRESSIVE EQUITY
 
     The pullback that we anticipated at the end of the first quarter finally
came to fruition. We believe that positive, although more moderate, returns are
likely going forward. Prospects remain good for sustained economic growth,
steady to lower bond yields and low inflation, along with steady corporate
profits.
 
     We continue to be quite positive on the prospects for quality growth
stocks. Companies that are able to provide above average earnings growth will
likely to continue to attract investors. As a result, the portfolio continues to
hold technology companies like Dell Computer, Cisco Systems, Microsoft and
Compuware; drug/medical device companies like Schering-Plough, Pfizer,
Bristol-Myers, and Boston Scientific; service companies like America Online and
Home Depot; financial companies including American Express and AIG.
 
     During the second quarter, the portfolio reduced its holdings from 38 names
to the current 33 names. The reduction was designed to take advantage of the
consolidation in the market. The funds were reallocated into current positions
that present good values at reduced prices, including increased positions in
Home Depot, American Express, AIG and Gap Stores.
 
     As we transition into the third quarter, the impact of Asia on our economy
in terms of interest rates and corporate profits will be determined. We remain
confident that second quarter earnings for our stocks will be solid. The key
will be to remain well-diversified in companies that can deliver consistent and
stable earnings growth in an otherwise turbulent global environment.
 
                              INTERNATIONAL EQUITY
 
     The international equity markets again endured volatility, as the first
quarter's recovery in Asia dramatically reversed in the second quarter. Hong
Kong's equity market fell nearly 27%, with other Asian countries following suit.
Japan ended down 4.5% as their banking reform package was met with skepticism.
 
     Enthusiasm in Europe continued, as many stock markets posted record highs.
The core EMU markets, France, Germany and Belgium, as well as Finland were among
the best performers.
 
     The portfolio benefited from stock selection in Finland, Germany and
Canada. The most notable Finnish holdings were Nokia and UPM-Kymmene. German
stocks -- Mannesmann, Deutsche Telekom and SAP AG -- continue to add value to
the portfolio.
 
     Exposure to Asia hurt performance, as well as underweighted positions in
France and Germany.
 
     Going forward, we do not see Asian markets turning around soon. However, as
bottom-up investors, we seek to invest in world class companies and look for
opportunities to buy stocks at favorable prices.

1.  ORGANIZATION AND BUSINESS
 
     Diversified Investors Portfolios (the "Series Portfolio"), a series trust
organized on September 1, 1993, under the laws of the State of New York, is
composed of thirteen different series that are, in effect, separate investment
funds: the Money Market Series, the High Quality Bond Series, the Intermediate
Government Bond Series, the Government/Corporate Bond Series, the Balanced
Series, the Equity Income Series, the Equity Value Series, the Growth & Income
Series, the Equity Growth Series, the Special Equity Series, the Aggressive
Equity Series, the High-Yield Bond Series, and the International Equity Series
(each a "Series"). The Declaration of Trust permits the Board of Trustees to
issue an unlimited number of beneficial interests in each Series. Investors in a
Series (e.g., investment companies, insurance company separate accounts and
common and commingled trust funds) will each be liable for all obligations of
that Series (and of no other Series).
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
     A.  SECURITY VALUATION
 
          Short-term securities having remaining maturities of 60 days or less
     are valued at amortized cost which approximates value. The amortized cost
     of a security is determined by valuing it at original cost and thereafter
     amortizing any discount or premium at a constant rate until maturity.
     Equity securities are valued at the last sale price on the exchange on
     which they are primarily traded or at the bid price on the Nasdaq system
     for unlisted national market issues, or at the last quoted bid price for
     securities not reported on the Nasdaq system. Bonds are valued at the last
     available price provided by an independent pricing service for securities
     traded on a national securities exchange. Bonds that are listed on a
     national securities exchange but are not traded and bonds that are
     regularly traded in the over-the-counter market are valued at the mean of
     the last available bid and asked prices by an independent pricing service.
     All other securities will be valued at their fair value as determined by
     the Board of Trustees.
 
     B.  REPURCHASE AGREEMENTS
 
          Each Series, along with other affiliated entities of the investment
     advisor, may enter into repurchase agreements with financial institutions
     deemed to be creditworthy by the Series investment advisor, subject to the
     seller's agreement to repurchase and the Series agreement to resell such
     securities at a mutually agreed upon price. Securities purchased subject to
     repurchase agreements are segregated at the custodian, and pursuant to the
     terms of the repurchase agreement must have an aggregate market value
     greater than or equal to 102% and 105% of domestic and international
     securities, respectively, of the repurchase price plus accrued interest at
     all times. If the value of the underlying securities falls below the value
     of the repurchase price plus accrued interest, the Series will require the
     seller to deposit additional collateral by the next business day. If the
     request for additional collateral is not met or the seller defaults on its
     repurchase obligation, the Series maintains the right to sell the
     underlying securities at market value and may claim any resulting loss
     against the seller. However, in the event of default or bankruptcy by the
     seller, realization and/or retention of the collateral may be subject to
     legal proceedings.
 
     C.  FOREIGN CURRENCY TRANSLATION
 
          The accounting records of the International Equity Series are
     maintained in U.S. dollars. The market values of foreign securities,
     currency holdings and other assets and liabilities are translated to U.S.
     dollars based on the prevailing exchange rates each business day. Income
     and expenses denominated in foreign currencies are translated at prevailing
     exchange rates when accrued or incurred. The Series does not isolate
     realized gains and losses attributable to changes in exchange rates from
     gains and losses that arise from changes in the market value of
     investments. Such fluctuations are included with net realized and
     unrealized gains or losses on investments. Net realized gains and losses on
     foreign currency

2.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     transactions represent net exchange gains and losses on disposition of
     foreign currencies and foreign currency forward contracts, and the
     difference between the amount of investment income receivable and foreign
     withholding taxes receivable recorded on the Series' books and the U.S.
     dollar equivalent of amounts actually received or paid. Net unrealized
     foreign exchange gains and losses arise from changes in the value of assets
     and liabilities other than investments in securities at fiscal year end and
     foreign currency forward contracts, resulting from changes in the exchange
     rates.
 
     D.  FOREIGN CURRENCY FORWARD CONTRACTS
 
          Each Series may enter into foreign currency forward contracts and
     forward cross currency contracts in connection with settling planned
     purchases or sales of securities or to hedge the currency exposure
     associated with some or all of the Series' portfolio securities. A foreign
     currency forward contract is an agreement between two parties to buy and
     sell a currency at a set price on a future date. The market value of a
     foreign currency forward contract fluctuates with changes in forward
     currency exchange rates. Foreign currency forward contracts are marked to
     market daily and the change in value is recorded by the Series as an
     unrealized gain or loss. When a foreign currency forward contract is
     extinguished, through delivery or offset by entering into another foreign
     currency forward contract, the Series records a realized gain or loss equal
     to the difference between the value of the contract at the time it was
     opened and the value of the contract at the time it was extinguished or
     offset. These contracts may involve market risk in excess of the unrealized
     gain or loss reflected in the Series' Statement of Assets and Liabilities
     and Statement of Operations. In addition, the Series could be exposed to
     risk if the counterparties are unable to meet the terms of the contracts or
     if the value of the currency changes unfavorably to the U.S. dollar.
 
     E.  OPTIONS
 
          Each Series, with the exception of the Money Market Series, may
     purchase and write (sell) call and put options on securities indices for
     the purpose of protecting against an anticipated decline in the value of
     the securities held by that Series. Index options are marked to market
     daily and the change in value is recorded by the Series as an unrealized
     gain or loss. A realized gain or loss equal to the difference between the
     exercise price and the value of the index is recorded by the Series upon
     cash settlement of the option. The use of index options may expose the
     Series to the risk that trading in such options may be interrupted if
     trading in certain securities included in the index is interrupted or the
     value of the securities in the index may not move in direct correlation
     with the movements of the Series portfolio. In addition, there is the risk
     the Series may not be able to enter into a closing transaction because of
     an illiquid secondary market.
 
     F.  FEDERAL INCOME TAXES
 
          It is the Series' policy to comply with the applicable provisions of
     the Internal Revenue Code. Therefore, no federal income tax provision is
     required.
 
     G.  SECURITY TRANSACTIONS AND INVESTMENT INCOME
 
          Security transactions are accounted for on a trade date basis (the
     date the order to buy or sell is executed). Dividend income is recorded on
     the ex-dividend date. Interest income is recorded on the accrual basis and
     includes amortization of premium and discount on investments. Realized
     gains and losses from securities transactions are recorded on the
     identified cost basis.
 
          All of the net investment income and realized and unrealized gains and
     losses from security transactions are determined on each valuation day and
     allocated pro rata among the investors in a Series at the time of such
     determination.

2.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     H.  OPERATING EXPENSES
 
          The Series Portfolio accounts separately for the assets, liabilities
     and operations of each Series. Expenses directly attributable to a Series
     are charged to that Series, while expenses attributable to all Series are
     allocated among them.
 
     I.  OTHER
 
          The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities at
     the date of the financial statements and the reported amounts of revenues
     and expenses during the reporting period. Actual results could differ from
     those estimates.

be delivered or transferred by the member firms no later than the close of
business on the next business day. As with other extensions of credit, the
Series may bear the risk of delay in recovery or even loss of rights in the
collateral should the borrower of the securities fail financially. The Series
