The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

parable index, because its average maturity (even though I short-ened it by one
year, as it became clear that interest rates were trending upward) remained
longer than the average maturity of the index. At year-end, the average matu-
rity of the Fund was 4.6 years and the index's was 3.6 years.
    I expect 2000 will offer more of the same, at least in the first half. We
believe the Fed will raise short-term interest rates in February from 5.50% to
6.00% and then desist. I've positioned the Fund for this likelihood. With its
somewhat longer average maturity, it may suffer more from a rate hike, but it
should do better in the stable interest-rate environment I expect to follow.
    The risk to this scenario is that the economy continues to boom, the stock
market continues to soar, and the Fed, fretting about inflation in general and
equity assets in particular, would try to deflate the stock market with a
string of rate increases. Bond investors would suffer from this medicine.
    This concludes my time as your portfolio manager. As my successor, Naomi
Urata will closely monitor the bond market and work to position the Fund to
make the best of the situation, whether rates are rising or falling.

    Interest rates continued to rise into year-end on fears the Federal
Reserve would raise rates again to contain a too-strong economy, con-
sumer spending, and buoyant stock markets. To further complicate mat-
ters, the global economy is on a fast mend, with international trade ex-
pected to increase. These factors are not comforting to a market which
reacts strongly to fears of inflation and excessive economic growth. I
believe the same themes will carry over into the new year.
    The SAFECO GNMA Fund finished the year ahead of its peers, but our higher
sensitivity to interest rates kept us behind the Merrill Lynch GNMA Index. The
SAFECO Fund and its peers were longer than the index, and longer bonds fared
poorly in the rising rate environment. For exam-ple, in the fourth quarter, 30-
year pass-through GNMAs

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

barely broke even, returning 0.44%. 15-year pass-throughs did marginally better
at 0.48%, while the 5- and 7-year balloons generated 0.72%.
    As rising rates cause the duration (sensitivity to interest rates) of mort-
gage-backed securities to lengthen, I actively shortened the Fund's average ma-
turity, especially in the last half of the year. The bulk of my trading in-
volved selling the longest assets, and defensive swaps. These were the right
moves; I just needed more of them.
    In the fourth quarter, Y2K concerns ruled Wall Street, and I consolidated a
number of smaller CMO positions, while there was a strong bid, with larger,
more liquid positions.
    At December 31, the Fund's average life and duration were 9.6 years and 4.8
years, compared to 8.6 years and 4.5 years for the GNMA indices. The Fund's
slightly longer average life and duration is due to its emphasis, about 69% of
net assets, on 30-year pass-throughs. The balance is invested in well-struc-
tured, intermediate- maturity CMOs.
    During the first quarter, I will be looking for more defensive strategies
and possibly allocating some of the assets into 1-year pass-throughs and 7-year
balloons, as well as more overlooked sectors that appear cheap.

    High-yield bonds proved to be the best fixed-income investment in
1999. (The Merrill Lynch High-Yield Index returned 2.51%.) The SAFECO
High-Yield Bond Fund proved to be a great choice for high-yield invest-
ors. For the year and quarter ended December 31, 1999, the Fund
outperformed its benchmark index.
    The year itself ended on a high note, with the best returns coming in the
fourth quarter. Fewer-than-expected new issues and stable cash flows lent a
positive technical tone to the market, and nearly all the Fund's holdings
showed some price increase. Cable and telecommunication issues such as
Bresnan, Metromedia Fiber, Psinet, and Rhythms NetConnections were the best
performers. 21st Century Telecom also rose significantly in price on the news
that RCN Corp. was acquiring the company. I used the

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

   I bought preferred stock in CSC Holdings, the parent company of

well-rated company.
   In addition to being overweighted in cable and telecommunication issues,
our large exposure to single-B-rated paper helped us outperform. That rating
category turned in the best performance in the high-yield market.
   The 30-day yield on the Fund climbed to end the year at 9.47%, while the
modified duration (sensitivity to interest rates) declined to 5.2 years. I
will continue to emphasize higher yields and lower interest-rate sensitivity
in order to minimize volatility in the Fund. I do expect volatility in the
market. Robust economic growth and tight labor markets make increases in the
Fed funds likely, and both the equity and bond markets traded off early in
2000 in anticipation of Fed action.

                           [PHOTO OF MICHAEL HUGHES]

    While the performance of the Managed Bond Fund continued to improve
to virtually mirror the Lehman Gov't./Corp. Index for the fourth quar-
ter, the annual performance, regrettably, trailed the benchmark. And the
absolute performance of both ventured back into negative territory.
    1999 was the worst year for the bond market since 1994, and the only other
year to post a negative annual return since 1973. Most of the Fund's
underperformance in the year occurred during the first half of 1999 -- when I
was optimistic. I thought economic growth would slow, inflation would remain
low and bonds would be stable, and had positioned the portfolio accordingly.
Consequently, the duration (sensitivity to changes in interest rates) of the
portfolio was too high.

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

    The strength of the global economic recovery fueled domestic
demand and added to our own economic growth. A reversal of the
late 1998 flight to quality (demand for the safety of U.S. Trea-
suries) caused a sharp increase in yields and volatility in the
market. Finally, even though actual inflation fell, fears of in-
flation caused the market to act as though inflation were rising.
    About halfway through the year, in order to soften the blow of increasing
economic growth and higher interest rates, I reduced the portfolio's duration
and increased its yield. As a result, our relative and absolute performance im-
proved.
    I intend to maintain the Fund's defensive posture until we have concrete
signs that higher interest rates are finally slowing the economy. In the
meantime, I see robust growth prompting the Federal Reserve to "tap on the
brakes" with a couple of rate increases. This should result in slightly higher
interest rates, a flatter or possibly inverted yield curve and, finally, a
slower economy.

    The rise in interest rates continued during the fourth quarter, mak-
ing 1999 the worst year in the bond market since 1994, and ending it on
a negative note for long-term tax-exempt investors.
    According to the Bond Buyer 40 Yield-to-Maturity Index, 30-year tax-
exempt yields at the beginning of 1999 were 5.17%. They ended the second quar-
ter at 5.54%, the third at 5.89%, and the year at 6.22%, over 1% higher than
where they began. Inflation concerns were behind the rise in yields.
    When rates rise, bond values fall. And the longer SAFECO Municipal Bond
Funds typically fall farther when rates rise for the same reasons they climb
higher when rates are dropping: Our strategy is to stay fully invested in long-
term bonds and to favor discounts. There is no arguing: longer bonds--though
more volatile--yield more than shorter ones. And, discount bonds--though more
volatile--offer greater appreciation potential. For investors who prefer a more
stable investment, SAFECO offers an intermediate-term municipal bond fund.
    At the beginning of 1999, long-term tax-exempt bonds were yielding 100% of
the yield on 30-year Treasury bonds. At mid-year, this ratio had dropped to 90%,
as munis strongly outperformed Treasuries during the spring. In mid-August,
munis cheapened; their yields climbed from 92% to 98% of Treasury yields. The
markets generally tracked each other in the fourth quarter, and the year ended
with the ratio at 96%, still historically cheap for tax-exempt bonds.
    Although there has been no evidence of increasing inflation (the nemesis of
fixed-income investors), the bond markets are still fixated on the Federal Re-
serve and its program of slowing the economy through interest rate increases.
Until there is hard evidence of the slower growth that many economists are
forecasting, it seems the Fed will continue its tight money policy, making a
bond market rally difficult. When that day of relief arrives, we expect it to
be dramatic and extensive since all possible bad news seems to be priced into
today's bond market.

    In the negative environment of 1999, the California Tax-Free Income
Fund with its long (25.5-year) average-weighted maturity fared poorly.
    Our core strategy of staying fully invested in long-term bonds
(which are more sensitive to changes in interest rates) produced below-
average returns as interest rates rose, just as it has produced superior
results when rates dropped. Over the longer term, the California Fund still
looks good. For the five years ended December 31, 1999, it was in the top
quartile of its category, ranking 17 out of 78 comparable funds, according to
Lipper, Inc. (For the ten years it is 14 of 37 funds, while it was 104 of 107
for the shorter one-year period.)
    As the California economy rebounded from its slump of a few years ago, the
normal premium

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

for California tax-exempt bonds (the 10-15 basis-point advantage over national
names) returned and was evidenced throughout 1999.
    The primary activity in the California Fund during 1999 was tax swapping
(simultaneously buying and selling similar bonds to realize losses for tax rea-
sons). I was able to offset all gains for the year as well as carry forward ad-
ditional losses to use in years to come. I hope to use them, and do additional
tax swaps, in 2000. I also sold many of the advance-refunded bonds that we had
accumulated in recent years.
    The Fund is positioned for a dramatic rebound should rates decline.

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

right call or advance refunding. When the bonds to be retired are not (or not
yet) callable, creative investment bankers offer to purchase them at a price
set by the issuer or determined by the holders in competition (a "Dutch
auction").
    The Fund sold bonds having a face value of $17,525,000 at prices signifi-
cantly above market levels to three issuers. The Long Island Power Authority
and Lower Colorado Power Authority conducted Dutch auction tenders, and the
Daughters of Charity National Health System offered to purchase two issues held
by the Fund at a fixed price. Facing deregulation, electric utilities are re-
structuring their balance sheets to become more competitive, while tenders for
hospital bonds were associated with consolidation.

penses or cash flow. For the year, the Fund was 26 of 133 intermediate-

was 17 of 97 similar funds.)

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

endure the rising rates better than its fellow funds.
    The municipal market, which always grinds to a halt at the end of the year,
did so earlier than usual, as many firms wanted to wrap things up early in case
Y2K complications made closing transactions difficult. The tone of the market
did nothing to encourage these firms to stay active until the ball dropped at
midnight.
    The SAFECO Intermediate-Term Municipal Bond Fund was also quiet during the
latest quarter. We saw little to interest us in the market, and we did no trad-
ing. We still intend to continue very slowly extending the average maturity of
the Fund (it was 5.8 years at year-end), but will take our time, looking for
opportunities to take advantage of changes in the market as they occur.

    The Fund generally underperforms its benchmark index and peers dur-
ing periods of rising rates, just as it outperforms in bull markets. The
year 1999 was no exception. The Insured Municipal Bond Fund performed

The performance graph compares a hypothetical $10,000 investment in the Fund to
a hypothetical investment in a relevant market index. The index is unmanaged and
includes no operating expenses or transaction costs. Past performance is not
predictive of future results. Principal value may fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.

AA continue to offer only two to five basis points additional yield compared to
similar insured bonds. This means there is very little incentive for buyers of
investment-grade bonds to settle for anything less than AAA-rated insured
bonds. The exception is hospital revenue bonds. The spread between insured and
uninsured hospital bonds, particularly those rated BBB, has increased.
    Most of the activity in the Insured Municipal Bond Fund during 1999 was tax
swapping, that is, I took advantage of lower prices by simultaneously purchas-
ing and selling similar bonds. Thus, the Fund maintained its positions while
realizing losses to offset current and future taxable gains. I plan to continue
to realize losses, and I hope to use them against gains, in 2000.

   The SAFECO Money Market Fund outpaced the average taxable money mar-
ket fund for the fourth quarter and the year 1999. The 12-month return
on the Fund was significantly higher than the 2.7% yearly increase in
the Consumer Price Index as well.
   Our above-average performance is mostly attributable to shortening the av-
erage maturity of the Fund and holding "floaters." (See discussion below.)
   Facing the risk that the Fed might raise short-term interest rates, I sig-
nificantly shortened the average maturity of the Fund from a high of 88 days
in April to 43 days at year-end. Indeed, the Fed raised rates three times dur-
ing the year from 4.75% to 5.50%, most recently in November. Being shorter
than the 53-day maturity of the average money fund reported by IBC Financial
Data has enabled me to capture higher rates a bit sooner than my peers. For
example, three-month commercial paper rates rose from a low of 4.73% in April
to 5.75% at year-end. Very close to Y2K, I was able to reinvest in commercial
paper at yields in the 6% range.
   I bought several corporate floaters that change yields as rates rise. The
Fund also owns several taxable municipal seven-day floaters that are even more
sen-sitive to rate changes, and yield 10 to 25 basis points higher than
similarly rated 30-day commercial paper. At year-end, rates on our taxable
municipals spiked as high as 7.85%, albeit only for a week. These investments
are particularly favorable in a Fedtightening environment, as they capture any
rate in-creases within seven days.
   As the economy continues at a strong pace with low unemploy-

ment and hints of rising inflation, the Fed is likely to raise rates again. In
anticipation, the market has already priced 0.5% of tightening into short-term
rates. I will maintain a short average maturity until I see signs that rates
have stabilized, and will continue to seek yield while working to maintain
safety in volatile market conditions.

    The SAFECO Tax-Free Money Market Fund began the last quarter of 1999
with a seven-day average yield of 3.05% and ended it yielding 3.80%. For
the year, the Fund compared well, outperforming its peers.
    The market, which was characterized by rising rates was friendly to
our portfolio with its heavy weighting in very short securities. Vari-
able rate demand options, or VRDOs, made up 71% of our portfolio at year end,
and their short maturity allows us to capture higher rates sooner than our
peers.
       The fourth quarter was quieter than the third in the tax-exempt
money market. We experienced some calls in the longer portion of our portfolio,
with little new-issuance activity. That is reflected in the make-up of our Fund.
At year-end, 71% of the

Fund was invested in variable rate demand option bonds (VRDOs), 26% in put
bonds, and 3% in notes. We held no commercial paper as of that date. These
figures represent an increase in VRDOs, and a decrease in both put bonds and
commercial paper.
    So what does the future have in store for the SAFECO Tax-Free Money Market
Fund? I plan to bring the percentage of VRDOs down to about two-thirds of the
Fund, as is our norm, with corresponding increases in the longer money market
products, such as put bonds, notes and commercial paper. January is always a
tight month in terms of supply, and a strong month in terms of demand as the
market is normally flush with cash from coupon payments and maturing paper to
be reinvested, and very few places to put it. After that supply/demand imbal-
ance is resolved, and Y2K fears have fully subsided, normal issuance and re-
marketing activity will resume and we should return to our usual portfolio
structure.

                         NOTES TO FINANCIAL STATEMENTS

1.  GENERAL
    This financial report is on 11 of the SAFECO Mutual Funds. Each Fund is a
series of one of the following trusts listed below. Each trust is registered
under the Investment Company Act of 1940, as amended, as a diversified, open-
end management investment company.
    SAFECO Taxable Bond Trust
      SAFECO Intermediate-Term U.S. Treasury Fund
      SAFECO GNMA Fund
      SAFECO High-Yield Bond Fund
    SAFECO Managed Bond Trust
      SAFECO Managed Bond Fund
    SAFECO Tax-Exempt Bond Trust
      SAFECO California Tax-Free Income Fund
      SAFECO Municipal Bond Fund
      SAFECO Washington State Municipal Bond Fund
      SAFECO Intermediate-Term Municipal Bond Fund
      SAFECO Insured Municipal Bond Fund
    SAFECO Money Market Trust
      SAFECO Money Market Fund
      SAFECO Tax-Free Money Market Fund
    Effective September 30, 1996, the Intermediate-Term U.S. Treasury, Managed
Bond, California Tax-Free Income, Municipal Bond, Washington State Municipal
Bond, and Money Market Funds began issuing two classes of shares - Class A and
Class B shares. Effective January 31, 1997, the High-Yield Bond Fund also began
issuing Class A and Class B shares. Unlike the no-load class of shares (which
are sold directly to the shareholder with no associated sales and distribution
charges), these classes of shares are sold by financial advisors to sharehold-
ers and have associated sales and distribution charges. Each class of shares
represents an interest in the net assets of the fund.
    In connection with issuing Class A and Class B shares, all of the above
mentioned funds (except the Money Market Fund) adopted a Plan of Distribution
("the Plan"). Under the Plan, Class A and Class B shares pay a service fee to
the distributor, SAFECO Securities Corp., for selling its shares at the annual
rate of .25% of the average daily net assets of the

                                     - 64 -

                         NOTES TO FINANCIAL STATEMENTS

Advisor Class. Class B shares also pay the distributor a distribution fee at
the annual rate of .75% of the average daily net assets of the Class B shares.
    Under the Plan, the distributor uses the service fees primarily to compen-
sate persons selling Class A and Class B shares for providing ongoing services
and the maintenance of shareholder accounts. The distributor uses the distribu-
tion fees primarily to offset the commissions it pays to financial advisors for
selling Class B shares.
    Subsequent Event. On January 18, 2000, the Board of Trustees voted to liq-
uidate and dissolve the SAFECO Washington State Municipal Bond Fund on March
31, 2000. Current shareholders may sell their shares or continue to hold them
until the liquidation date, when the then-current value of their investment
will be returned to them.

2. SIGNIFICANT ACCOUNTING POLICIES

    The following is a summary of significant accounting policies consistently
followed by the Funds in the preparation of their financial statements. The
policies are in conformity with generally accepted accounting principles.
    Security Valuation. Bonds are stated on the basis of valuations provided by
a pricing service, which uses information with respect to transactions in
bonds, quotations from bond dealers, market transactions in comparable securi-
ties and various relationships between securities in determining value. When
valuations are not readily available, securities are valued at fair value as
determined in good faith by the Board of Trustees. Investments in equity secu-
rities are valued at the last reported sales price, unless there are no trans-
actions in which case they are valued at the last reported bid price. Invest-
ments in the money market funds consist of short-term securities maturing
within thirteen months from the date of purchase. Securities in the Tax-Free
Money Market Fund with maturities of more than thirteen months have floating
rates and/or demand features which qualify them as short-term securities. Secu-
rities purchased at par are valued at cost. All other securities in the money
market funds are valued at amortized cost, which approximates market value.
Other temporary investments purchased at par are valued at cost.

                         NOTES TO FINANCIAL STATEMENTS

    Security Transactions. Security transactions are recorded on the trade
date. The cost of the portfolios is the same for financial statement and Fed-
eral income tax purposes. Realized gains and losses from security transactions
are determined using the identified cost basis.
    Securities Purchased on a When-Issued Basis. Securities purchased on a
when-issued or delayed basis may be settled a month or more after the trade
date. The securities purchased are carried in the portfolio at market and are
subject to market fluctuation during this period. These securities begin earn-
ing interest on the settlement date. As commitments to purchase when-issued
securities become fixed, the Funds segregate liquid assets in an amount equal
to the total obligation.
    Income Recognition. Bond premiums and original issue discounts are amor-
tized to either call or maturity dates. In the Tax-Exempt Bond Trust, market
discount on bonds purchased after April 30, 1993 is recorded as taxable income
at disposition. Interest is accrued on bonds and temporary investments daily.
The Managed Bond Fund has elected to amortize premiums on securities purchased
above par value. The funds in the Taxable Bond Trust have not elected to amor-
tize premiums on securities purchased above par value.
    Dividends and Distributions to Shareholders. Net investment income is de-
clared as a dividend to shareholders of record as of the close of each busi-
ness day and payment is made as of the last business day of each month. Net
gains realized from security transactions, if any, are normally distributed to
shareholders at the end of December.
    Income dividends and capital gain distributions are determined in accor-
dance with income tax regulation which may differ from generally accepted ac-
counting principles. These differences are primarily due to differing treat-
ments for wash sale deferrals. Accumulated net investment income and realized
gain/loss may include temporary financial reporting and tax basis differences
which will reverse in subsequent year.
    Federal Income and Excise Taxes. Each Fund intends to comply with the re-
quirements of the Internal Revenue Code applicable to regulated investment
companies by distributing substantially all taxable income to their sharehold-
ers in a manner which results in no tax to the Funds. Therefore, no Federal
income or excise tax provision is required. In addi-

tion, the Tax-Exempt Bond Trust and the Tax-Free Money Market Fund intend to
satisfy conditions which will enable them to pay dividends which, for share-
holders, are exempt from Federal income taxes. Any portion of dividends repre-
senting net short-term capital gains, however, is not exempt and is treated as
taxable dividends for Federal income tax purposes.
    Estimates. The preparation of financial statements in conformity with gen-
erally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the report-
ing period. Actual results could differ from those estimates.

               Report of ERNST & YOUNG LLP, Independent Auditors

To the Board of Trustees and Shareholders of the SAFECO Taxable Bond Trust,
SAFECO Managed Bond Trust, SAFECO Tax-Exempt Bond Trust, and SAFECO Money Mar-
ket Trust

    We have audited the accompanying statements of assets and liabilities, in-
cluding the portfolios of investments, of the SAFECO Taxable Bond Trust (com-
prising, respectively, the SAFECO Intermediate-Term U.S. Treasury Fund, the
SAFECO GNMA Fund, and the SAFECO High-Yield Bond Fund), the SAFECO Managed
Bond Trust (comprising the Managed Bond Fund), the SAFECO Tax-Exempt Bond
Trust (comprising, respectively, the SAFECO California Tax-Free Income Fund,
the SAFECO Municipal Bond Fund, the SAFECO Washington State Municipal Bond
Fund, the SAFECO Intermediate-Term Municipal Bond Fund, and the SAFECO Insured
Municipal Bond Fund), and the SAFECO Money Market Trust (comprising, respec-
tively, the SAFECO Money Market Fund and SAFECO Tax-Free Money Market Fund) as
of December 31, 1999, and the related statements of operations for the year
then ended, the statements of changes in net assets and the financial high-
lights for each of the periods indicated therein. These financial statements
and financial highlights are the responsibility of the Trusts' management. Our
responsibility is to express an opinion on these financial statements and fi-
nancial highlights based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and per-
form the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An au-
dit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements and financial highlights. Our proce-
dures included confirmation of securities owned as of December 31, 1999, by
correspondence with the custodian and brokers. An audit also includes assess-
ing the accounting principles used and significant estimates made by manage-
ment, as well as evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
each of the respective funds constituting the SAFECO Taxable

erally accepted in the United States.

Year 2000 Readiness (Unaudited)

    All Year 2000 readiness work was completed prior to December 31, 1999. The
Funds have experienced no disruption in their operations or service levels, and
do not expect to incur any future disruptions or expense in connection with the
year 2000 issue.

Shareholder Meeting (Unaudited)

    A joint special meeting of the Funds' shareholders was held on March 30,
1999, at which time the shareholders voted to approve changes to the Funds'
fundamental investment policies and approved an amended and restated investment
advisory contract, including a change in the fee structure. Shareholders
elected the Board of Trustees and ratified the selection of Ernst & Young LLP
as independent auditors. The results of that meeting are presented below.
