                             PRESIDENT'S MESSAGE

         We are pleased to present the 1996 semi-annual report of the
         NACo Variable Account.

         Equity investments provided a respectable return for the first
         half of 1996 with the major market indices holding comfortably
         in double digits. Fixed-income investments, however, did not
         perform as well with the average bond fund showing slightly
         negative performance for the period. This was due to rising
         interest rates and lingering inflation fears.

         The U.S. economy showed signs of increasing strength during
         the first half of the year. The question remains: will growth
         fall back to the perceived inflation-free path by itself or
         will the Federal Reserve have to step in and enforce
         moderation? Recent economic statistics, such as the July
         unemployment report, point in the direction of some
         moderation. Also, fierce competition in all consumer-goods
         markets make inflationary price increases very difficult. One
         way or the other, we expect slower economic growth in the near
         future.

         Financial assets will remain the preferred individual
         investment option because they will continue providing
         security, liquidity, and income and growth.

         We appreciate your confidence in the Nationwide Insurance
         Enterprise and in our life and annuity products. You have our
         assurance that your personal satisfaction with our products
         and service is our highest priority.



                                            /s/ JOSEPH J. GASPER

                                                Joseph J. Gasper, President

How to Read the Semi-Annual Report


This Semi-Annual Report is sent to all customers who own a Nationwide annuity
with all or some of the funds in the NACo Variable Account (the Account). The
Account is a separate account trust which offers investment options in
twenty-eight mutual funds from sixteen mutual fund houses.

The Semi-Annual Report has three major financial sections.

STATEMENT OF ASSETS, LIABILITIES AND CONTRACT OWNERS' EQUITY

This statement, beginning on page 8, lists all the funds in the Account, the
number of shares owned, the amount paid for the shares (i.e., cost) and their
market value on June 30, 1996. The funds are presented in alphabetical order.
The market value of the assets change as the underlying mutual fund shares
change in value. As contract owners make exchanges between the funds, the number
of shares in each fund increases and decreases. When money is deposited
(withdrawn) by contract owners, shares of the mutual funds are bought (sold) by
the Account. The total market value of the funds is equal to the Total
investments.

Accounts receivable, if applicable, is an asset of the Account for money market
fund shares or reinvested dividend shares added to the contract owners'
accounts, but not yet added to Total investments. Total investments plus
Accounts receivable equals Total assets.

Accounts payable, if applicable, is a liability of the Account for money market
fund shares deducted from the contract owners' accounts, but not yet deducted
from Total investments.

Total assets minus Accounts payable equals Contract owners' equity. For a
summary of Contract owners' equity by fund series turn to page 10.

STATEMENTS OF OPERATIONS AND CHANGES IN CONTRACT OWNERS' EQUITY

These statements, found on page 14, show the activity in the Account from
January 1 to June 30, 1996, 1995 and 1994.

The Investment activity section shows the changes in unrealized gain or loss of
the mutual funds in the Account, realized gain or loss as shares of the funds
are bought and sold, and dividends and capital gains earnings from the
underlying mutual funds. The Equity transactions section illustrates the
purchase payments received by the Account as new contracts are sold, existing
contract owners deposit additional funds, money is withdrawn, contracts are
canceled and annuity benefits are paid.

Expenses are the charges associated with the contract. Note 2 on page 16
outlines these charges.

Net change in contract owners' equity equals Investment activity plus Equity
transactions minus Expenses.

The Contract owners' equity at the beginning of the period plus the Net change
in contract owners' equity equals the Contract owners' equity at the end of the
period. Contract owners' equity at the end of the calendar year will equal the
Contract owners' equity at the beginning of the next year.

SCHEDULES OF CHANGES IN UNIT VALUE

As a contract owner, you invest in the mutual funds offered in your annuity
contract. However, you do not buy shares of the mutual fund. Instead, the
Account buys shares of the fund and you in turn purchase units of the Account.
The number of units you own will not change unless you contribute to or withdraw
money from your account. The value of your contract can change based on the
value of the units you own. For example, if you purchase 100 units at $10 per
unit, the value of your contract is $1,000. If the value of the units increases
to $12 per unit, your contract value increases to $1,200. Therefore, to
determine the value of your account, multiply the number of units of each fund
you own by the fund's unit value.

The Schedules of Changes in Unit Value, beginning on page 18, show you the unit
value at the beginning of the period and at the end of the period. The
percentage increase (decrease) in unit value shows how it changed in value. This
is computed by subtracting the beginning unit value from the ending unit value
and dividing the difference by the beginning unit value. This can be used as a
measure of the performance of the funds over the three semi-annual periods
reported.

As you review the following pages of the Semi-Annual Report, the Notes to
Financial Statements, beginning on page 15, will also help explain and clarify
the various statements and schedules.

      The contract owners' equity is affected by the investment results of each
fund, equity transactions by contract owners and certain expenses (see note 2).
The accompanying financial statements include only contract owners' purchase
payments pertaining to the variable portions of their contracts and exclude any
purchase payments for fixed dollar benefits, the latter being included in the
accounts of the Company.

   (c) Security Valuation, Transactions and Related Investment Income

      The market value of the underlying mutual funds is based on the closing
net asset value per share at June 30, 1996. The cost of investments sold is
determined on the specific identification basis. Investment transactions are
accounted for on the trade date (date the order to buy or sell is executed) and
dividend income is recorded on the ex-dividend date.

   (d) Federal Income Taxes

Operations of the NACoVA form a part of, and are taxed with, operations of the
Company, which is taxed as a life insurance company under the Internal Revenue
Code. The assets in this account are held pursuant to contracts with entities
which are exempt from federal income tax. Because of this exemption, no taxes
need be provided for investment income or realized and unrealized capital gains.
Annuity payouts and withdrawal payments are taxable as wages when received by
the participants.

   (e) Use of Estimates in the Preparation of Financial Statements

      The preparation of financial statements in conformity with generally
accepted accounting principles may require management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities, if any, 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.

(2) EXPENSES

      No deduction for a sales charge is made from the purchase payments for
these contracts. However, if an owner terminates the contract and directs the
Company to withdraw all or part of the contract value held in the Account for
less than sixteen (16) years, the Company will, with certain exceptions, assess
a contingent deferred sales charge by deducting an amount from each participants
account. This charge will be equal to not more than 4% in the first year,
declining to 1% in the fifteenth year, of the lesser of all purchase payments
made on behalf of a participant prior to the date of withdrawal, or the amount
withdrawn. No sales charges are deducted on redemptions used to purchase units
in the fixed investment options of the Company. Sales charges may be reduced or
eliminated upon negotiated conversion of the contracts to other investment
programs offered by the Company or its affiliates.

      The following charges are deducted by the Company: A mortality risk
charge, an expense risk charge and an administration charge which are assessed
through the daily unit value calculation. The morality risk charge and the
expense risk charge are equal to an annual rate of 0.10% and 0.40% respectively.
Beginning May 1, 1996, the administration charge was based upon the aggregate
balance of assets held under the Contract by each Member County, as follows:

                I               Up to $10                 .45%
               II            Over $10 to $25              .40%
               III           Over $25 to $50              .30%
               IV               Over $50                  .20%
</TABLE>

The administration charge is determined using the December 31 asset balance and
is effective at the next expense tier on the following May 1.

      Contract owners may negotiate an exchange privilege with the Company. The
exchange privilege provides for transfers of units among the various investment
options for each participant's account. The number of transfers allowed, and any
administrative charges associated therewith, are subject to negotiation between
the contract owner and the Company.

(3) SCHEDULE I

      Schedule I presents the components of the change in the unit values, which
are the basis for contract owners' equity. This schedule is presented in the
following format:

            o  Beginning unit value - Jan. 1

            o  Reinvested capital gains and dividends
               (This amount reflects the increase in the unit value due to
               capital gains and dividend distributions from the underlying 
               mutual funds.)

            o  Unrealized gain (loss)
               (This amount reflects the increase (decrease) in the unit value
               resulting from the market appreciation (depreciation) of the 
               underlying mutual funds.)

            o  Contract charges
               (This amount reflects the decrease in the unit value due to the
               mortality risk charge, expense risk charge and administration 
               charge discussed in note 2.)

            o  Ending unit value - June 30

            o  Percentage increase (decrease) in unit value.
