         Solid asset management expertise and quality investment choices are
among the key reasons that investors choose the Nationwide Family of Funds. In
1999, we expanded our ability to deliver both.
         Amidst continued strong momentum in our mutual fund asset management
business and growing demands from investors for mutual funds and other financial
products, Nationwide Financial announced, in February 1999, the formation of a
new asset management company, Villanova Capital.
          Villanova Capital combines the solid mutual fund investment management
capabilities previously available through Nationwide Advisory Services with the
stable value investment expertise provided by another Nationwide Financial
Company, Morley Financial Services, Inc. These two organizations come together
to form a $22 billion asset management stronghold, uniquely positioned for
future growth.
         We expect to achieve that future growth through selected acquisitions
of small- to mid-sized institutional investment firms. In addition, we
anticipate hiring key portfolio managers with strong performance records.
Finally, we have already made significant progress in building a leadership team
that includes business and industry experts from top U.S. financial
organizations.
         Our shareholders, in turn, can expect to see increased portfolio
management capabilities, expanded investment choice, and technologically
innovative tools and support services.

YEAR IN REVIEW

         Stock mutual funds in the Nationwide Family finished the 12-month
period ended October 31, 1999, trailing their respective benchmarks. These
disappointing returns came amidst continued momentum in the stock market, which
was bolstered by an improved global economic outlook. U.S. equities, as measured
by the unmanaged Wilshire 5000 Index (a widely followed indicator of broad stock
market trends), surged +26.9%. The unmanaged S&P 500 Index (an indicator of
trends among large "blue-chip" stocks) climbed +25.7%.
         Select stocks held by our equity funds turned in spectacular
performances. However, their strong individual showings did not outweigh an
across-the-board tendency by our managers to avoid unproven technology issues.
         In an environment in which a few "hot" technology stocks (particularly
internet companies that, in many cases, have no reportable earnings) have
dominated the market, our equity managers have chosen to tune out the "hype,"
focusing instead on companies with sustainable competitive performance records.
This was a conscious decision that we believe will benefit our investors in the
long run.
         In the bond market, a precipitous rise in interest rates resulted in
the weakest performance witnessed by investors since 1994. For the 12 months
ended October 31, 1999, the Lehman Brothers Aggregate Bond Index (a widely
followed indicator of broad bond market trends) inched up just +0.53%.
         Fixed income funds in the Nationwide Family stayed within tight range
(150 basis points) of their benchmarks. However, both the funds and their
respective benchmarks produced negative absolute returns.

PORTFOLIO MANAGEMENT
         As we start the new fiscal year, we will keep a strong focus on
investment quality. Our tenured team of fund managers will continue to seek
competitive performance in all asset categories--emphasizing the importance of
delivering what we promise to investors. We intend to stay true to each fund's
stated objective and strategy, focusing our efforts on achieving above-market
performance without subjecting our investors to unnecessary risks.
         Our existing team of managers has built a solid foundation upon which
we will continue to build our investment management capabilities. For example,
Chuck Bath, 14-year manager of our flagship Nationwide Fund, has achieved his
solid long-term performance record without straying from his strategy of
buying--and holding--high-quality companies with proven track records.

INVESTMENT CHOICE
         Investors desire choice. They also demand solutions. Over the past 12
months, we have focused on delivering both. The Prestige Advisor Series,
introduced in November 1998, offers investors the opportunity to choose from
among five mutual
<PAGE>   3

funds: three U.S. stock funds, an international stock fund, and a balanced fund.
Each of these funds is sub-advised by a nationally recognized institutional
money manager that was selected and is monitored by Villanova Capital. In 2000,
we plan to further expand our menu to include specialty portfolios offering
exposure to specific market sectors or industries--in the U.S. and abroad.
         We're also committed to expanding our market reach. Two of our funds,
our flagship Nationwide Fund and the Nationwide Growth Fund, are now available
through advisors that use fund supermarkets sponsored by Fidelity Investments
Institutional Brokerage Group, TD Waterhouse Institutional Services, and Charles
Schwab Institutional OneSource. We expect to continue to expand our external
distribution capabilities to make it even easier and more convenient for
investors to gain access to our funds.

INNOVATIVE TOOLS AND SERVICES
         As we enhance our asset management capabilities and product offerings,
we recognize the importance of communicating our progress to our investors as
well as to the Nationwide representatives and other financial advisors who guide
them in making sound investment decisions. We understand the value of clear,
candid information that is easy to access and regularly updated. Our goal is to
make it easy for advisors and investors to learn about our products and how they
fit within an overall financial plan.
         As we move into 2000, our investors can expect to see innovative tools
designed to provide them with compelling examinations of investment topics,
including global economic trends, market and industry sectors, and portfolio
management strategies. These tools will be easily accessible via our website
(www.nationwidefunds.com) or by calling us toll-free.

THE YEAR AHEAD
         Villanova Capital enters the year 2000 as a new organization poised for
growth--in our investment management capabilities, in our product offerings, and
in the tools that we provide to our investors and their advisors. As we look
ahead, we are not starting on a new mission. Rather, we are continuing to build
on the solid investment management franchise that has delivered strong returns
to our investors for decades.

MID CAP GROWTH FUND

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

         The total return for the Nationwide Mid Cap Growth Fund (Class D) for
the 12-month period ended October 31, 1999, was 13.31%*, compared to 21.07% for
the S&P MidCap 400 Index.

         During the fall of 1998, investors took pains to reduce or avoid risk
in their portfolios, leading to large declines in financial and technology
stocks. As the fiscal year began last November, the Federal Reserve was
preparing its third interest rate decrease. This liquidity boost served to shore
up investor confidence, and the stock market took off.

         One trend that has solidly emerged over the past 12 months, despite
subsequent interest rate increases, is the investor's greater appetite for risk.
The dramatic increases in technology stocks, particularly internet issues that
in many cases have never earned a profit, are evidence of this trend. Increased
risk-tolerance can also be seen through the extraordinary price performance of
many initial public offerings. Such offerings have proven to be a difficult way
to earn money over the long term, but the short-term performances have been
nothing short of astonishing.

         The Mid Cap Growth Fund benefited from certain of the above trends
during the year. Our largest holding, Advent Software, gained more than 150%
over the 12-month period. Advent makes investment management software to
automate and integrate operations for asset managers. After a decline last fall
with other technology stocks, Advent rocketed back with stellar sales growth and
exciting new product momentum. Despite paring back our position for
diversification purposes, the stock remained nearly 9% of the portfolio. Other
names that delivered excellent returns included many of the
semiconductor-related companies, such as Microchip Technology, KLA-Tencor and
Cognex. Each of these stocks rose between 90%-150% during the year following
their declines during the fall of 1998.

         One sector that was particularly challenging for the Mid Cap Growth
Fund was health care. Among the companies that disappointed were Covance and
Quintiles, both contract research organizations. Both stocks were sold after
price drops that followed disappointing revenue and earnings news. Manor Care
was also a disappointment. This nursing home operator faced challenges in the
new Medicare reimbursement regulations. While these challenges impacted their
operations significantly in 1999, I believe the company is adjusting and will be
able to return to the growth track in coming years.

         I plan to continue looking for high-quality growth companies for the
portfolio. This emphasis on quality may mean that investors in the Fund pass up
some of the more speculative types of gains that appear to be occurring in the
market. However, this strategy is intended to reduce some volatility if
investors' appetites for risk decrease dramatically.

    B) 12b-1 fee. Had Class A or B been in existence for the time periods
    presented, the Fund's performance for such classes would have been lower as
    a result of the additional expenses.
 ** These returns do not reflect the effects of a sales charge.

    declines to 0% after 6 years.

GROWTH FUND

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

     The total return for the Nationwide Growth Fund (Class D) for the 12-month
period ended October 31, 1999, was 17.07%*, compared to a return of 25.67% for
the S&P 500 Index.

     During the 1999 fiscal year, the best performing stocks in the Growth Fund
tended to be technology companies. Microsoft, Intel, MCI Worldcom, and BMC
software all provided returns in excess of the S&P 500 during the period. Intel,
Home Depot and Bed Bath and Beyond were added to the Fund during a period of
weakness that developed in growth stocks during the summer. All were strong
performers for the entire 12-month period. Also, while financial stocks have
been weak for most of 1999, two of the Fund's large holdings, Axa Financial and
American International Group, had competitive returns when considering the
entire 12-month period.

     The main sources of weakness in the Fund came from two areas. The first was
in drug stocks, which performed poorly all year, both due to fear of rising
interest rates, and fear of possible federal health care reform. However, the
drug stocks in our portfolio have strong future product development, prominent
franchising position, and patent protection. The other area of weakness came
from a handful of stocks that suffered earnings disappointments and subsequent
severe price declines. In some cases, such as with Newell and Covance, these
disappointments casted doubt on the long-term fundamental outlooks of the
companies. In those instances, the Fund sold the stock. In other instances-for
example, Avon, Ceridian, and Cardinal Health-it still looks as though the
long-term fundamentals are intact and the short-term market reaction has been
too extreme, and we have held those positions.

     The Fund's strategy continues to concentrate on adding high-quality growth
stocks and selling issues that are less well positioned. These buys have been
predominantly in the large-cap area, with some additions in mid cap when
opportunities have arisen. It is discouraging that some of the recent additions
under this strategy, such as Ceridian and Cardinal Health, had short-term
earnings disappointments. However, these additions were made with long-term
results in mind, and as long as the fundamentals remain sound, this strategy
should prove effective.

All figures showing the effect of a sales charge reflect the maximum charge
possible, because it has the most dramatic effect on performance data.

   * These returns represent performance achieved prior to the creation of the
     class (5/11/98), excluding the effect of the 0.25% (Class A) or 1.00%
     (Class B) 12b-1 fee. Had Class A or B been in existence for the time
     periods presented, the Fund's performance for such classes would have been
     lower as a result of the additional expenses.

NATIONWIDE FUND

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

         The total return for the Nationwide Fund (Class D) for the 12-month
period ended October 31, 1999, was 10.27%*, compared to 25.67% for the S&P 500
Index.

         The Nationwide Fund underperformed the S&P 500 due to the relatively
weak performance of both pharmaceutical and financial stocks. These areas were
hurt during the year due to increasing earnings growth in other sectors of the
market as well as rising interest rates.

         Warner-Lambert and Schering-Plough, the Fund's two largest holdings,
continue to achieve impressive, steady growth from their drug portfolios. I am
confident this consistent growth will continue in the future, and therefore I am
comfortable with these large positions. Also, in early November (after fiscal
year end), Warner-Lambert announced a definitive agreement to merge with
American Home Products ("AHP"). Within hours of that announcement, Pfizer made
an unsolicited bid for Warner-Lambert. Both AHP and Pfizer are holdings in the
Fund, and I am optimistic that either scenario will be beneficial for both
companies going forward. It is also likely that these announcements will lead to
other positive combinations within the pharmaceutical industry.

         Other large positions in the Fund are Wells Fargo and Mellon Bank.
These two unique financial service franchises are well positioned to continue to
outperform their industry peers. Although the financial services sector has been
weak, the passage of the new financial services legislation along with a
leveling-off of interest rates should once again allow these stocks to lead the
market.

         World class consumer products companies Black & Decker and Quaker Oats
have shown consistent sales and earnings growth over the past couple of years
but continue to lag the overall market due to a general lack of interest in
consumer products companies.

         The largest new holding in the portfolio is Pharmacia & Upjohn. This
company was formed a few years ago through the merger of Pharmacia AB and The
Upjohn Corp. After a few challenging years and a couple of significant
management changes, this company now appears well positioned for consistent
growth over the next three to five years. Although the company's new drug
pipeline contains no blockbusters, it does look quite promising with two
potential new drugs addressing sizable market opportunities.

         The Fund's outstanding performer during the year was Tiffany & Co. The
stock more than tripled from its lows last October and is now roughly 3% of the
Fund's assets. I feel the company possesses a superior franchise with a
favorable long-term outlook.

         As I have been doing during recent years, I continue to concentrate
portfolio holdings in high-quality names. The market has not differentiated
significantly between such quality companies and higher-risk businesses. I
continue to feel that the market is not sufficiently weighing the risks inherent
in many technology industries. This has become most evident in the internet
sector where many companies with completely unproven business models command
incredibly high, premium valuations. I intend to avoid these situations and
concentrate on high-quality companies with proven track records that are selling
at reasonable prices.

BOND FUND

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

         The total return for the Nationwide Bond Fund (Class D) for the
12-month period ended October 31, 1999, was -1.24%*, compared to -0.66% return
for the Lehman Brothers Government/Corporate Bond Index.

         These poor returns were caused by sharply higher interest rates as the
U.S. economy's continued strength led to an improving world economy. Despite
negative absolute returns, performance for the fund was competitive with the
benchmark over the trailing 12 months. The 30-year Treasury is now yielding
6.16%, up from 5.15% a year ago, while the two-year Treasury has increased to
5.78% from just 4.12%.

         Last year the Federal Reserve aggressively eased interest rates to head
off a liquidity crisis from pulling the U.S. into a recession, stabilize U.S.
markets, and block potential worldwide economic problems. Almost everyone
believed significant slowing of the economy was the best case for 1999. Instead,
economic growth actually accelerated in the U.S., and the widening trade deficit
has pulled the world economy along. Growth has averaged more than 4%, and even
Japan seems on the road to recovery. Many economists now believe multiple
increases in the funds rate, to 6% or higher, are likely some time in 2000.

         With corporate bond spreads at the widest levels of the decade a year
ago, I would have expected corporates to have performed exceptionally well as
the economy steamed ahead and profit growth was superb. But they did not.
Corporate spreads tightened for about six months, but when the Federal Reserve
moved to a tightening bias, they reversed course and began widening. As year
2000 concerns mounted, fears of heavy corporate supply further pushed spreads
all the way back to the levels of last year.

         I believe the combination of interest rates near their highs of the
last few years and spreads at the widest of the decade has set the bond market
and the Nationwide Bond Fund up for good returns next year almost regardless of
what happens. If the Federal Reserve is successful in slowing the economy,
interest rates will decline. But a recession is unlikely with the rest of the
world on the mend. If the economy does not slow, rates will probably drift
higher, but not nearly to the same extent as last year. Therefore, the bond
market is already priced for a couple of tightening moves. With an improving
world economy, corporate profits should remain strong and spreads are likely to
tighten, especially once we get into the new year and Y2K fears are behind us.

All figures showing the effect of a sales charge reflect the maximum charge
possible, because it has the most dramatic effect on performance data.

 * These returns represent performance achieved prior to the creation of the
   class (5/11/98), excluding the effect of the 0.25% (Class A) or 0.85% (Class
   B) 12b-1 fee. Had Class A or B been in existence for the time periods
   presented, the Fund's performance for such classes would have been lower as a
   result of the additional expenses.
** These returns do not reflect the effects of a sales charge.
 1 A 4.50% front-end sales charge was deducted.
 2 A 5.00% contingent deferred sales charge (CDSC) was deducted. The CDSC
   declines to 0% after 6 years.

NATIONWIDE(R) MUTUAL FUNDS

TAX-FREE INCOME FUND

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

         The total return for the Nationwide Tax-Free Income Fund (Class D) for
the 12-month period ended October 31, 1999 was -3.21%*, compared to -1.78% for
the Lehman Brothers Municipal Bond Index.

         Yields were higher across the yield curve and the bond markets in
general produced negative returns. By maintaining a longer duration than the
index over the past year, the Fund underperformed the index as interest rates
trended higher. Rising interest rates coupled with weakened demand from its two
major institutional purchasers, property and casualty insurance companies and
municipal bond mutual funds, created a volatile period for the municipal bond
market.

         Municipal bond demand was strongest from individuals, while the demand
from the institutional buyers was relatively anemic. The fixed income markets
had a continuing positive tone in the aftermath of the Federal Reserve's
announcement that it was reassuming a neutral policy stance after having
increased rates 25 basis points in June and again in August. However,
institutional selling pressure began to pick up during the month of August, as
the property and casualty insurance companies began to seek higher returns from
taxable bonds. Since the profitability results were uniformly disappointing for
property and casualty companies, demand for municipal bonds remained soft.
Municipal bond mutual funds also witnessed weakened demand from individuals
since April, when they began to seek higher returns through direct purchase of
municipal bonds. This also resulted in increased fund redemption. Bond funds
used this weakened environment to lock in losses through tax swapping. In this
instance, funds focused on swapping out of bonds with short calls and lower
coupons into new issues with strong call protection. As September rolled around,
the market continued to struggle in the face of heavier new issue supply and
continued reduced demand from the key institutional sectors. However, at the end
of October, the markets received positive economic data that calmed inflationary
fears and reflected slower growth in the economy. As a result, investors began
to return to the municipal bond market and prices began to increase.

         Municipal bond investors should continue with caution as we expect to
see reduced demand from investors until municipal bonds become cheap enough to
represent relative value as an investment option. Municipal bonds generally
become compelling as an asset class when their price as a percentage of
Treasuries is more than 95% on the long end of the yield curve. Historically,
investors who purchase municipal bonds when this relationship occurs are
rewarded in the future. Fund management will maintain a long-term view, continue
to monitor market developments and make appropriate adjustments in portfolio
holdings as needed. The Nationwide Tax-Free Income Fund has a duration of 8.0
years, while the benchmark, the Lehman Brothers Municipal Bond Index, has a
duration of 7.2 years.

LONG-TERM U.S. GOVERNMENT
BOND FUND
MANAGEMENT DISCUSSION OF FUND PERFORMANCE

         The total return for the Nationwide Long-Term U.S. Government Bond Fund
(Class D) for the 12 month period ended October 31, 1999, was -2.39%*, compared
to -1.20% for the Merrill Lynch Government Master Index.
         The last 12 months have been difficult for bond investors. By
maintaining a longer duration than the index over the past year, the Fund
performed the index as interest rates trended higher. The Federal Reserve's
decision to tighten was initially characterized as reversing the 1998 easing
policy to contain the Asian crisis. Further tightening was done to prevent
potential inflation as the U.S. economy continued to exhibit strength. Yields on
long-term Treasuries have risen by 1.00%-1.50% over the period.
         The rising interest rate environment has obscured the fundamental value
available in the U.S. Government market. From a historical perspective, the
current yields available are attractive. For example, 10-year Agency bonds can
be purchased at an additional yield of 0.70% above Treasuries, which is nearly
double the level at which identical bonds could be purchased in July 1998.
         Although it has been a difficult period for long-term investors, the
correction appears close to ending. Even if the Federal Reserve was to raise
rates one or two more times, the long end of the yield can perform well since
inflation expectations would diminish. The Fund maintains its exposure in this
longer maturity part of the yield curve market with nearly 50% of assets
invested here.
         When I become convinced the correction in interest rates is over, I
plan to deploy the remaining cash reserves and sell the short duration
mortgage-backed positions in favor of intermediate positions. The combination of
these moves should allow for shareholders to benefit from future decreases in
interest rates.

         The Fund continues to be invested in sectors of the Government Agency
and mortgage-backed markets perceived to be undervalued. Approximately 20% of
portfolio assets are invested in the mortgage-backed market, 49% is invested in
Government Agencies, and 25% in U.S. Treasuries.

INTERMEDIATE U.S. GOVERNMENT
BOND FUND
MANAGEMENT DISCUSSION OF FUND PERFORMANCE

           The total return for the Nationwide Intermediate U.S. Government Bond
Fund (Class D) for the 12 month period ended October 31, 1999, was -0.93%*,
compared to -1.20% for the Merrill Lynch Government Master Index.
           The last 12 months have been difficult for bond investors. By
maintaining a shorter duration than the index over the past year, the Fund
outperformed the index as interest rates trended higher. The Federal Reserve's
decision to tighten was initially characterized as reversing the 1998 easing
policy to contain the Asian crisis. Further tightening was done to prevent
potential inflation as the U.S. economy continued to exhibit strength. Bonds
have been especially hard hit across the entire yield curve and intermediate
bonds were not spared, as the five-year Treasury yields have risen nearly 1.75%
over the period.
           The rising interest rate environment has obscured the fundamental
value available in the U.S. Government market. From a historical perspective,
the current yields available are attractive. For example, 10-year Agency bonds
can be purchased at a yield of 0.70% above Treasuries, which is nearly double
the level the identical bonds could be purchased in July 1998.
           During the past year I have focused on improving the overall quality
of the portfolio. Mortgage holdings with better risk/reward profiles have been
added, and I have swapped into larger Agency issues to improve the liquidity of
the portfolio. The U.S. Treasury position has been increased from 8% to 34% of
holdings. The Treasury holdings are intermediate duration callable issues, with
yields that approach those available on Agencies and long-duration 20-year
Treasuries. The 20-year part of the U.S. Treasury curve yields approximately
0.40% more than the 30-year issues and has performed well in the flattening
yield curve environment.
           The Fund is currently maintaining its exposure to the bond market by
investing in a barbell of short and longer maturities. A switch to a portfolio
with an intermediate exposure is expected soon to take advantage of an
environment of stable or falling interest rates.

MONEY MARKET FUND

MANAGEMENT DISCUSSION OF FUND

           The total return for the Nationwide Money Fund Prime Shares for the
12-month period ended October 31, 1999, was 4.61%, compared to 2.63% for the
Consumer Price Index.
           The fiscal year began in November 1998 as the Federal Reserve reduced
the Federal Funds rate, the interest rate banks charge depository institutions
for loans, to 4.75% from 5.00%. The Federal Reserve increased the rate back to
5.00% on June 30, 1999, and to 5.25% on August 24, 1999. Officials at the
Federal Reserve are concerned that demand may be increasing too rapidly relative
to the supply of labor and other resources. They are also concerned about the
U.S. trade deficit and the rise in equity markets.
           In this volatile economic environment, the Fund has maintained an
average maturity below 45 days. This enabled it to earn competitive returns for
investors as interest rates trended higher during the second half of the fiscal
year.
           Extra emphasis is being placed on liquidity going into the new year.
While we don't expect an exodus of shareholders or computer malfunctions, the
Fund is only investing in issues that have a strong secondary market.
           All investments are in compliance with Rule 2a-7, Investment Company
Act of 1940. This rule governs the investment decisions of registered money
market mutual funds. Eligible investments must have two ratings in the highest
rating category from nationally recognized securities rating organizations:
Moody's Investors Services, Inc., Standard & Poor's Corporation, Duff & Phelps,
Fitch IBCA, Inc., or Thompson Bank Watch.
           A determination of minimal credit risk for all approved issuers is
made prior to investment for the Fund. The maximum investment in a single issuer
is 5% of fund assets and the maximum industry concentration is 25% of fund
assets.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nationwide Mutual Funds ("NMF" or the "Trust"), formerly known as Nationwide
Investing Foundation III, is an open-end management investment company. NMF was
created under the laws of Ohio as an Ohio business trust pursuant to a
Declaration of Trust dated as of October 31, 1997, as amended as of November 5,
1999, and is registered under the Investment Company Act of 1940, as amended.
The Trust offers shares in fifteen separate series, or mutual funds, each with
its own investment objectives. This report contains the financial statements and
financial highlights of the eight series (the "Funds") listed below.

- -  Nationwide Mid Cap Growth Fund
- -  Nationwide Growth Fund
- -  Nationwide Fund
     (together referred to as the "Stock Funds")
- -  Nationwide Bond Fund
- -  Nationwide Tax-Free Income Fund
- -  Nationwide Long-Term U.S. Government Bond Fund
- -  Nationwide Intermediate U.S. Government Bond Fund
     (together referred to as the "Bond Funds")
- -  Nationwide Money Market Fund
     (referred to as the "Money Market Fund")


The Stock and Bond Funds currently offer Class A, B, and D Shares. Class A
Shares are purchased with a front-end sales load and a 0.25% 12b-1 fee. Class B
Shares are subject to a contingent deferred sales charge ("CDSC") on redemption
and a 1.00% 12b-1 fee for the Stock Funds and an 0.85% 12b-1 fee for the Bond
Funds. Class D Shares are purchased with a front-end sales load but no 12b-1 fee
and are only offered to certain investors. The Money Market Fund cur- rently
offers two classes of shares called Prime and Class R Shares. The Class R Shares
were first offered to the public on January 4, 1999, and the existing shares of
the Money Market Fund were renamed Prime Shares. The Prime Shares have no sales
charge, or 12b-1 fee, but do have a 0-10% administrative servicing fee. Class R
Shares are purchased with no sales charge but do have a 0.15% 12b-1 fee, which
is currently being waived, and a 0.25% administrative servic- ing fee.

(a) SECURITY VALUATION

    (1) Mid Cap Growth, Growth, Fund, Bond, Tax-Free Income, Long-Term and
        Intermediate U.S. Government Bond Funds:

        Securities traded on a national securities exchange are valued at the
        last quoted sale price as provided by an independent pricing agent.
        Securities traded in the over-the- counter (OTC) market are valued at
        the last quoted sale price, or if there is no sale price, the last
        quoted bid price as provided by an independent pricing agent. U.S
        Government securities are valued at the last quoted bid price as
        provided by an independent pricing agent. All other debt securities are
        valued by a combination of daily quotes and matrix evaluations.

    (2) Money Market Fund:

        Securities are valued at amortized cost, which approximates market
        value, in accordance with Rule 2a-7 of the Investment Company Act of
        1940, as amended.

    (3) All Funds:

        The value of a repurchase agreement generally equals the purchase price
        paid by the Fund (cost) plus the interest accrued to date. The seller,
        under the repurchase agreement, is required to maintain the market value
        of the underlying collateral at not less than the value of the
        repurchase agreement. Securities subject to repurchase agreements are
        held by the Federal Reserve/Treasury book-entry system or by the Fund's
        custodian or an approved sub-custodian.

        Securities for which reliable market quotations are not available or for
        which an independent pricing agent does not provide a value or provides
        a value that does not represent fair value in the judgement of the
        Fund's investment adviser are valued in accordance with procedures
        authorized by the Trust's Board of Trustees.

(b) SECURITY TRANSACTIONS AND INVESTMENT INCOME

    Security transactions are recorded on the trade date. Dividend income is
    recorded on the ex-dividend date. Interest income is recorded on an accrual
    basis and may include, where applicable, the pro rata amortization of
    premium or discount.

(c) FEDERAL INCOME TAXES

    Each Funds' policy is to qualify as a regulated investment com- pany under
    the Internal Revenue Code and to distribute all tax- able income to
    shareholders. Therefore no provision has been made for federal income taxes
    as it is the intention of the Funds to continue such qualification. To the
    extent net realized gains are offset through the application of a capital
    loss carryover, they will not be distributed to shareholders and will be
    retained by the applicable Fund. Withholding taxes have been paid or
    provided for in accordance with the applicable tax rates and rules.

    As of October 31, 1999, the Bond and Tax-Free Income Funds had net capital
    loss carry forwards in the amounts of $7,241,215 and $1,065,849,
    respectively. If unused, the Bond Fund carry forwards will expire within 3
    to 8 years and the Tax- Free Income Fund carry forwards will expire within 5
    to 8 years.

(d) DIVIDENDS TO SHAREHOLDERS

    (1) Mid Cap Growth, Growth, and Fund:

        Dividend income, if any, is declared and paid quarterly and is recorded
        on the ex-dividend date.

    (2) Bond, Tax-Free Income, Long-Term and Intermediate U.S. Government Bond,
        and Money Market:

        Dividend income is declared and recorded daily and paid monthly.

    (3) All Funds

        Distributable net realized capital gains, if any, are declared and
        distributed at least annually.

        Dividends and distributions to shareholders are determined in accordance
        with federal income tax regulations, which may differ from generally
        accepted accounting principles. These "book/tax" differences are
        considered either permanent or temporary in nature. In accordance with
        AICPA (American Institute of Certified Public Accountants) Statement of
        Position 93-2, permanent differences are reclassified within the capital
        accounts based on their nature for federal income tax purposes;
        temporary differences do not require reclassification. Dividends and
        distributions that exceed net investment income and net realized gains
        for financial reporting purposes but not for tax purposes are reported
        as dividends in excess of net investment income and net realized gains.
        To the extent distributions exceed current and accumulated earnings and
        profits for federal income tax purposes, they are reported as
        distributions of paid-in-capital. These reclassifications have no effect
        upon the net asset value of the respective Funds.

        Accordingly, as of October 31, 1999, undistributed net investment
        income, undistributed net realized gains and capital paid in excess of

Money Market          (1,822)       222,236      (220,414)

(e) EXPENSES

    General expenses of the Trust, not directly attributable to a series or to
    any class of shares, are allocated to the Funds based upon each Fund's
    relative average net assets or some other appropriate basis, as approved by
    the Trust's Board of Trustees. Once these expenses are allocated to a Fund,
    they are sub- allocated to the classes based on total settled shares
    outstanding of each class for the Bond and Money Market Funds, and total
    shares outstanding of each class for the Stock Funds.

    Direct expenses of a Fund are allocated to that Fund and sub- allocated to
    the classes by the methods mentioned above.

    Direct expenses of a class are allocated to that class unless otherwise
    directed by the Trust's Board of Trustees. During the year ended October 31,
    1999, no expenses were otherwise directed.Distribution and administrative
    servicing fees are borne by the specific class of shares to which they
    apply.

(f) USE OF ESTIMATES

    The preparation of financial statements, in conformity with generally
    accepted accounting principles, requires management to make estimates and
    assumptions. These estimates 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 period. Actual results could differ from those
    estimates.

    distributed to share holders for each of the respective Funds.

(b) The transfer of all assets, subject to liabilities, of the NIF Money Market
    Fund to a series of NMF which bears the same name, in exchange for shares of
    the new series in NMF (now known as the Prime Shares), which were
    distributed to the shareholders of the NIF Money Market Fund.

(c) The transfer of all assets, subject to liabilities, of the NIF II U.S.
    Government Income Fund to a series of NMF which bears the name Nationwide
    Intermediate U.S. Government Bond Fund, in exchange for Class D shares of
    Nationwide Intermediate U.S. Government Bond Fund, which were distributed to
    shareholders of the NIF II U.S. Government Income Fund.

(d) The transfer of all assets, subject to liabilities, of the FHIT Cash Reserve
    Fund to a series of NMF (now known as the Prime Shares) which bears the name
    Nationwide Money Market Fund, in exchange for shares of the Nationwide
    Market Fund, which were distributed to shareholders of the FHIT Cash Reserve
    Fund.

(e) The transfer of all assets, subject to liabilities, of the FHIT Growth Fund
    to a series of NMF which bears the name Nationwide Mid Cap Growth Fund, in
    exchange for Class D Shares of the Nationwide Mid Cap Growth Fund, which
    were distributed to shareholders of the FHIT Growth Fund.

(f) The transfer of all assets, subject to liabilities, of the FHIT U.S.
    Government Bond Fund to a series of NMF which bears the name Nationwide
    Long-Term U.S. Government Bond Fund, in exchange for Class D Shares of the

6. YEAR 2000 (UNAUDITED)

VMF, VSA and NAS have developed and implemented a plan to address issues related
to the Year 2000. The problem relates to many existing computer systems using
only two digits to identify a year in a date field. These systems were designed
and developed without considering the impact of the upcoming change in the
century. If not corrected, many computer systems could fail or create erroneous
results when processing information dated after December 31, 1999. VMF, VSA and
NAS have completed an inventory and assessment of all computer systems and have
implemented a plan to renovate or replace all applications that were identified
as not Year 2000 compliant. VMF, VSA and NAS have also tested each application
for its Year 2000 Compliance.

Systems supporting the Fund's infrastructure, such as telecommunica- tions,
voice and networks, have also been tested, renovated or replaced, and are
compliant. VMF's, VSA's and NAS' assessment of Year 2000 issues has also
included non-information technology systems with embedded computer chips.

In addition to resolving internal Year 2000 readiness issues, VMF, VSA and NAS
are surveying significant external organizations (business part- ners) to assess
if they will be Year 2000 compliant. VMF, VSA and NAS continue their efforts to
identify external risk factors and have developed contingency plans as part of
its ongoing risk-management strategy.

7. FEDERAL INCOME TAX INFORMATION (UNAUDITED)

For corporate shareholders, 100% of the Growth Fund and 100% of the Fund income
dividends and short-term capital gain distributions in the fiscal year ended
October 31, 1999, qualify for the corporate dividend received deduction.

All of the distributions paid by the Tax-Free Income Fund during the fiscal year
ended October 31, 1999, are exempt from federal income tax.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

THE BOARD OF TRUSTEES AND SHAREHOLDERS
NATIONWIDE MUTUAL FUNDS

    We have audited the accompanying statements of assets and liabilities of the
Nationwide Mutual Funds (comprised of Nationwide Mid Cap Growth Fund, Nationwide
Growth Fund, Nationwide Fund, Nationwide Bond Fund, Nationwide Tax-Free Income
Fund, Nationwide Long-Term U.S. Government Bond Fund, Nationwide Intermediate
U.S. Government Bond Fund, and Nationwide Money Market Fund) (collectively, the
Funds), including the statements of investments, as of October 31, 1999, and the
related statements of operations for the year then ended, the statement of
changes in net assets for the years in the two-year period then ended, and the
financial highlights for each of the periods indicated herein. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
October 31, 1999, by correspondence with custodians and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, 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 the
Funds as of October 31, 1999, the results of their operations for the year then
ended, the changes in their net assets for the years in the two-year period then
ended, and financial highlights for the periods indicated herein, in conformity
with generally accepted accounting principles.
