It hardly seems possible, but the first half of 1996 has drawn to a close. And
believe it or not, the Dow Jones Industrial Average -- the now-100-year-old
bellwether for the stock market -- stands some 500 points higher than it did in
January. A spectacular pace to be sure -- faster than the market's historical
average of 10% a year.
 
But make no mistake, the financial markets have been buffeted by more volatility
this year than they -- and we -- have experienced in some time.
 
Indeed, the relatively measured rise in the stock market averages masks some
rather abrupt corrections in many issues, especially in some of the more
unseasoned sectors of the market. The bond market, too, has proven to be
noticeably rambunctious these first six months, with long rates, widely expected
as the year began to move towards 5%, nudging instead above 7%.
 
Not so surprisingly, all of this commotion is leaving many folks in and around
the financial markets a bit unnerved. Considering how far the markets have come,
in a way, it's only natural to fear they may be "running out of gas". But,
remember, it wasn't that long ago, just over two years in fact, when similar
anxieties surrounded the financial markets -- when fears of the "big correction"
so dominated investor psychology.
 
Of course, the so-called conventional wisdom of that time proved to be not so
wise, and the prophets of doom proved to be not so insightful. Nevertheless, it
wasn't easy to hold the course in such a volatile market. But investors who did
stick to their plans throughout it all have more than likely been rewarded for
it. Handsomely perhaps. Our hats are off to all of you.
 
We're pleased the C.A.S.E. Reserve Variable Annuity could play a part. We remain
proud of the manner in which the C.A.S.E. Management, Inc., portfolio managers
have guided and are positioning funds in these remarkable times. Please take a
few minutes and review the personal comments from these professionals regarding
the C.A.S.E. Reserve Portfolios and just how they've been investing for them. We
invite you to evaluate these reports and review the data, including major equity
positions and industry weightings. All of this information is intended to
provide an insight into what has been some of the industry's finest performance.
 
As for the rest of 1996, we're really not interested in making predictions on
what will or will not happen. After all, in the short term, the markets are
unpredictable. But long term, they're inevitable. The secret to wealth
accumulation in the market in the past has been long-term investing and not
worrying about the interim peaks and troughs. History has shown that investors
often saw better results the longer they held their investment. We're in it for
the long term -- we are investors.
 
If it's true that success solicits success, then we're justified in our
optimistic outlook for this year and for years after that. The Portfolios of the
C.A.S.E. Reserve Variable Annuity are managed not only with long-term results in
mind but long-term relationships as well. Our highest priority remains the
safety of the funds you've entrusted to us. We respect your personal task of
financial planning and appreciate the opportunity to help.
 
                                                       Sincerely yours,
 
                                                       /s/ JOHN R. KENNEY

The C.A.S.E. Growth Portfolio commenced operations on May 1, 1995, and has just
completed its first full year of operations. Its investment objective is
preservation and growth of capital. This is achieved through investments in
common stocks of small-to-medium-sized companies. For the six-month period ended
June 30, 1996, the Portfolio posted a total return of 6.77%. By comparison, the
Standard & Poor's Index of 500 Common Stocks returned 10.10% and the Dow Jones
Industrial Average returned 11.70% for the same period.
 
Generally, our strategy is to invest in stocks of companies with
well-above-average management, solid balance sheets, below market price to
earnings ratios (on both a leading and a lagging basis), above market insider
and institutional buying, and earnings estimates that are being revised upwards.
While generally employing a buy-and-hold posture until fundamentals dictate a
change, the Portfolio may use short-term strategies to take advantage of
changing market conditions.
 
The stock market continues to be dominated by earnings as it reaches new highs.
In fact, of the two dozen fundamental methodologies used professionally to
evaluate investments, the leading factors governing price movement are earnings
related -- quarterly earnings surprise factors, projected earnings changes,
quarterly earnings per share growth, earnings projections, and insider activity
for 1996. As the economy continues to grow, our emphasis has switched to
companies more dependent on the domestic economy.
 
Our approach assumes a softer, slower paced market. In place of a broad-based
movement, certain areas of the economic structure appear better situated than
others. For example, our studies reflect that companies dependent on the
domestic economy have performed well. The economic sectors of technology, energy
and consumer spending are leading the performance race. We expect these trends
to continue through the summer.
 
Stocks that exhibit fundamentals of exceptional strength will ordinarily do
better than the market in good, as well as bad, times. The broad reach and
economic scope of our study disciplines lend themselves to investing in
selective economic periods, when volatility and uncertainty are present.
Therefore, our approach seems well suited to the period ahead.

The C.A.S.E. Growth & Income Portfolio commenced operations on May 1, 1995, and
has just completed its first full year of operations. Its objective is to seek
high current income and moderate growth through investments in well-priced,
well-managed, large, stable and growing companies. The Portfolio invests in
stocks of companies that pay dividends, have measurable growth rates, and have
demonstrated capital appreciation that exceeds the rate of inflation. For the
six-month period ended June 30, 1996, the Portfolio returned 8.07%. The Standard
& Poor's Index of 500 Common Stocks returned 10.10% for the same period.
 
Our research disciplines look for companies with strong balance sheets,
dependable cash flows, high profitability, favorable valuations, and a strong,
upward trend in earnings and dividend growth. By maintaining the value
discipline and investing in companies with growth potential, we believe this
offers an excellent core investment strategy for investors that desire to take a
defensive position. This strategy is intended to keep pace with the S&P 500, but
be less volatile. Its primary focus of growth is balanced with value and
preservation of capital.
 
By design, the C.A.S.E. Growth & Income Portfolio invests in companies with
price/earnings ratios that are nearly 25% less than the markets, on a 12-month
leading and 12-month lagging basis. These same companies exhibit year-over-year
earnings advancements above 10%. On a conservative value basis, their 10-year
comparatives are only 65% of the S&P 500. With its stocks displaying strong
fundamental underpinnings, and earnings growth rates double the market's, the
Portfolio appears well suited for the current investment climate and its stated
objective.

The C.A.S.E. Quality Growth Portfolio commenced operations on May 1, 1995, with
an objective to seek preservation and growth of capital. The Portfolio invests
primarily in common stocks of large, well-managed, well-priced companies with
defined markets and financial strategies. For the six-month period ended June
30, 1996, the Portfolio gained 4.94%. The Standard & Poor's Index of 500 Common
Stocks advanced 10.10% for the same period.
 
This Portfolio is well suited for those investors who are interested in
preservation of capital and maintaining a low-risk growth position in the
current market. Equities in general have rallied to a point where any bad news,
especially disappointing earnings, would be difficult to ignore. The current
economy, however, seems to be growing faster than most forecasters predicted
earlier this year. This has resulted in mixed performance within the market and
within most sectors. The C.A.S.E. Quality Growth Portfolio stresses quality of
earnings and companies exhibiting stability and solid growth potential.
 
As opposed to a broad-based movement, certain areas of the economic structure
appear more favorable than others. As a matter of policy, we resist any
temptation to time markets. Our sector and industry weightings reflect our best
judgment of the near- and long-term direction of our economy as a whole and the
stock market in particular. The portfolio composition stresses the markets'
strongest economic sectors in down markets, like manufacturing, consumer
products, finance and utilities, and offers better preservation of capital than
other strategies.
 
In terms of the strategic alignment, our price/earnings ratio (on both a
12-month leading and 12-month lagging basis) is more conservative than the
average Standard & Poor's 500 ratio. Our average stock is also revising its
earnings estimates upward and the year-over-year growth of sales and earnings
average is above 15%. Stocks that exhibit "above the market" fundamentals
ordinarily perform better than the general market.
 
The companies that were selected are broadly diversified, well managed, and
reflect balance sheets that provide a basis for future confidence. We monitor
two dozen of the industry's most advanced and reliable study disciplines. We
believe that if we hold fast to our discipline for uncovering companies with
above average characteristics and below market risk comparatives, we will
achieve reasonable returns in both good and bad market environments.

WRL SERIES FUND, INC.
NOTES TO FINANCIAL STATEMENTS
(UNAUDITED)
- --------------------------------------------------------------------------------
 
JUNE 30, 1996
 
NOTE 1 - ORGANIZATION AND SUMMARY OF
           SIGNIFICANT ACCOUNTING POLICIES
 
     The WRL Series Fund, Inc. (the "Fund") is a diversified, open-end,
investment management company registered under the Investment Company Act of
1940, as amended. The Fund was incorporated on August 21, 1985 as a Maryland
corporation and commenced operations on October 2, 1986.
 
     The Fund consists of a series of investment portfolios, including the
C.A.S.E. Growth Portfolio, the C.A.S.E. Growth & Income Portfolio, and the
C.A.S.E. Quality Growth Portfolio (the "Portfolios"). Shares of the Portfolios
are sold to the WRL Series Annuity Account (the "Annuity Account") of Western
Reserve Life Assurance Co. of Ohio ("WRL"), to fund benefits under the C.A.S.E.
Reserve Variable Annuity Contracts. The Separate Account contains three
investment options referred to as sub-accounts, each of which upon instructions
received from contract owners of C.A.S.E. Reserve Variable Annuity Contracts,
invests in a corresponding C.A.S.E. Portfolio.
 
     The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from these estimates.
 
A.  VALUATION OF INVESTMENTS
 
    Securities held by the Portfolios are valued at market value, except for
    short-term debt securities. Short-term debt securities maturing in 60 days
    or less are valued on the amortized cost basis, which approximates market
    value. Stocks are valued at the latest sale price on the last business day
    of the fiscal period as reported by the principal securities exchange on
    which the issue is traded or, if no sale is reported for a stock, the latest
    bid price is used. Bonds are valued using prices quoted by a major dealer in
    bonds which offers a pricing service. Certain pricing methodologies, such as
    matrix pricing of bonds, may involve the use of estimates and actual sales
    prices may differ. Securities for which quotations may not be readily
    available are valued as determined in good faith in accordance with
    procedures established by and under the general supervision of the Fund's
    Board of Directors.
 
    The value of foreign securities are translated into U.S. dollars using spot
    foreign exchange rates.
 
B.  SECURITY TRANSACTIONS AND INVESTMENT INCOME
 
    Security transactions are recorded on the trade date. Security gains and
    losses are calculated on the first-in, first-out basis for both tax and
    financial reporting purposes. Dividend income is recorded on the ex-dividend
    date, and interest income, including amortization of bond premium and
    accretion of discount, is accrued daily. Dividend income on foreign
    securities is recorded net of foreign tax withholdings.
 
    The accounting records of the Fund are maintained in U.S. dollars. For
    transactions denominated in a currency other than the U.S. dollar, purchases
    and sales of securities, income received, and expenses paid are translated
    into U.S. dollars at the foreign exchange spot rate on the date the
    transaction is recorded. Currency gain and loss is also calculated on
    payables and receivables that are denominated in foreign currencies. The
    payables and receivables are generally related to security transactions and
    income.
 
    The unrealized gain or loss on forward foreign currency contracts is due to
    the difference between the foreign exchange contract rate and the foreign
    exchange forward rate applicable to that contract at the end of the period.
    This gain or loss becomes realized when the contract is closed or settled.
 
    Futures contracts and options are valued based upon daily settlement prices
    with the fluctuations in value recorded as unrealized gains and losses.
    These gains and losses become realized when the position is closed. The
    risks associated with the use of options and futures contracts involve the
    possibilities of an illiquid market and an imperfect correlation between the
    value of the instrument and the underlying security.
 
C.  FEDERAL INCOME TAXES
 
    It is the Fund's policy to distribute substantially all of its taxable
    income and capital gains to its shareholders and otherwise qualify as a
    regulated investment company under the Internal Revenue Code. Pursuant to
    Code Section 4982(f), regulated investment companies serving as funding
    vehicles for life insurance company separate accounts are not subject to
    excise tax distribution requirements. Accordingly, no provision for Federal
    income taxes has been made.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
(UNAUDITED)
- --------------------------------------------------------------------------------
 
NOTE 1 - ORGANIZATION AND SUMMARY OF
           SIGNIFICANT ACCOUNTING
           POLICIES (CONTINUED)
 
    Income distributions and capital gain distributions are determined in
    accordance with income tax regulations, which may differ from generally
    accepted accounting principles. These differences are primarily due to
    differing treatments for such items as wash sales, foreign currency
    transactions, net operating losses and capital loss carryforwards.
 
D.  DIVIDENDS AND DISTRIBUTIONS
 
    Dividends of the Portfolios are declared and reinvested semi-annually, while
    capital gain distributions are declared and reinvested annually. Dividends
    and distributions of the Fund are generally paid to and reinvested by the
    Separate Account on the next business day after declaration.
 
E.  ORGANIZATION COSTS
 
    All costs incurred in connection with the formation of the Fund and its
    portfolios were paid by WRL.
 
NOTE 2 - INVESTMENT ADVISORY AND
           TRANSACTIONS WITH AFFILIATES
 
A.  INVESTMENT ADVISORY
 
    The Fund has entered into an annually renewable investment advisory
    agreement for the Portfolios with WRL as investment adviser. The Fund pays
    to WRL, and charges to each respective Portfolio, advisory fees each month
    at the following annual rate expressed as a percentage of the average daily
    net assets of the respective Portfolio:
 
<TABLE>
<CAPTION>
              PORTFOLIO            PERCENT OF ASSETS
    -----------------------------  -----------------
    <S>                            <C>
    C.A.S.E. Growth                        .80%
    C.A.S.E. Growth & Income               .80%
    C.A.S.E. Quality Growth                .80%
</TABLE>
 
    WRL has entered into a sub-advisory agreement with C.A.S.E. Management, Inc.
    Pursuant to the agreement, fifty percent of the advisory fee paid to WRL is
    due to C.A.S.E. Management, Inc.
 
    WRL currently voluntarily waives its advisory fees to the extent a
    portfolio's normal operating expenses exceed the percentage of net assets of
    the portfolio as listed below:
 
<TABLE>
<CAPTION>
              PORTFOLIO            PERCENT OF ASSETS

    <S>                            <C>
    C.A.S.E. Growth                       1.00%
    C.A.S.E. Growth & Income              1.50%
    C.A.S.E. Quality Growth               1.50%
</TABLE>
 
    The Portfolios are charged for expenses that specifically relate to their
    individual operations. All other operating expenses of the Fund that are not
    attributable to a specific portfolio are allocated based upon the
    proportionate number of policy and contract owners of the underlying
    sub-accounts. WRL directly incurs and pays these operating expenses relating
    to the Fund, which subsequently reimburses WRL. All normal operating
    expenses that exceed the established expense limit set forth above will be
    borne by WRL.
 
B.  AFFILIATES
 
    WRL is an indirect wholly-owned subsidiary of AEGON USA, Inc., which is an
    indirect wholly-owned subsidiary of AEGON nv, a Netherlands corporation.

</TABLE>
 
NOTE 4 - FEDERAL INCOME TAX MATTERS
 
     The income, expenses, gains and losses on security transactions attributed
to each Portfolio for accounting purposes are also attributed to that Portfolio
for federal income tax purposes. Gains and losses on forward currency contracts,
if applicable, are treated as ordinary income for federal income tax purposes
pursuant to Section 988 of the Internal Revenue Code.
 
     Each Portfolio has and will continue to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies, and
accordingly, has made or intends to make sufficient distributions of net
investment income and net realized gains, if any, to relieve it from all federal
and state income taxes and federal excise taxes.
 
     The net capital loss carryforwards noted below as of December 31, 1995, if
applicable, are available to offset future realized capital gains through the
periods listed. Each Portfolio will elect to treat the net capital losses
incurred in the two month period ended December 31, 1995, (Post-October Losses),
if applicable, as having been incurred in the following fiscal year. The
aggregate cost of investments and composition of unrealized appreciation and
depreciation for federal income tax purposes as of June 30, 1996 are as follows:

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 5 - FINANCIAL HIGHLIGHTS
 
     The Financial Highlights for each Portfolio contains a chart (the
"comparison chart") setting forth Average Annual Total Return ("total return")
and a comparison of the change in value of a $10,000 investment in that
Portfolio to one or more broad based market indices. In the comparison chart and
the total return set forth in "Financial Highlights", the total return and the
change in value of the Portfolio reflect the advisory fee and all other
Portfolio expenses and include reinvestment of dividends and capital gains; they
do not reflect the charges against the corresponding sub-accounts or the charges
and deductions under the applicable annuity contracts. Where a portfolio's
period from inception is less than one year, the total return shown is not
annualized. The indices referred to in the comparison charts are unmanaged and
are used as a general measure of market performance; with the exception of the
Wilshire 5000 Index, they assume reinvestment of dividends and capital gains and
all indices do not include any management or investment expenses.
 
     The ratio of expenses to average net assets in the financial highlights is
net of advisory fee waiver (see Note 2). The June 30, 1996 ratio is annualized,
along with the ratio of net investment income to average net assets. Without the
advisory fee waived by WRL, the ratio would be as follows:

JUNE 30, 1996
 
NOTE 1 - ORGANIZATION AND SUMMARY OF
           SIGNIFICANT ACCOUNTING POLICIES
 
     The WRL Series Annuity Account (the "Annuity Account") was established as a
variable accumulation deferred annuity separate account of Western Reserve Life
Assurance Co. of Ohio ("WRL") and is registered as a unit investment trust
("Trust") under the Investment Company Act of 1940, as amended.
 
     The Annuity Account holds assets that support the benefits under flexible
payment variable accumulation deferred annuity contracts (the "Contracts")
issued by WRL, including the C.A.S.E. Reserve Variable Annuity. The Annuity
Account equity transactions are accounted for using the appropriate effective
date at the corresponding accumulation unit value.
 
     The C.A.S.E. Reserve Variable Annuity investment options, referred to as
sub-accounts, are the C.A.S.E. Growth Sub-Account, the C.A.S.E. Growth & Income
Sub-Account, and the C.A.S.E. Quality Growth Sub-Account. Each sub-account
invests in the corresponding portfolio of the WRL Series Fund, Inc. (the
"Fund"), a registered management investment company under the Investment Company
Act of 1940, as amended. The investment manager for these three Portfolios is
C.A.S.E. Management, Inc.
 
     The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from these estimates.
 
     The following significant accounting policies, which are in conformity with
generally accepted accounting principles for unit investment trusts, have been
consistently used in preparation of the Trust's financial statements.
 
A.  VALUATION OF INVESTMENTS
 
    The investments in the Fund's shares are stated at the closing net asset
    value ("NAV") per share as determined by the Fund on June 30, 1996.
    Investment transactions are accounted for on the trade date, using the Fund
    NAV next determined after receipt of sale or redemption order without sales
    charges. Dividend income and capital gain distributions are recorded on the
    ex-dividend date. The cost of investments sold is determined on a first-in,
    first-out basis.
 
B.  FEDERAL INCOME TAXES
 
    The operations of the Annuity Account are a part of and are taxed with the
    total operations of WRL, which is taxed as a life insurance company under
    the Internal Revenue Code. Under current law, the investment income of the
    Annuity Account, including realized and unrealized capital gains, is not
    taxable to WRL. Accordingly, no provision for Federal income taxes has been
    made.
 
NOTE 2 - CHARGES AND DEDUCTIONS
 
     Charges are assessed by WRL in connection with issuance and administration
of the Contracts.
 
A.  CONTRACT CHARGES
 
    No deduction for sales expenses are made from the purchase payments. A
    contingent deferred sales charge may, however, be assessed against contract
    values when withdrawn or surrendered.
 
    On each anniversary through maturity date, WRL will deduct an annual
    contract charge as partial compensation for providing administrative
    services under the Contracts.
 
B.  SUB-ACCOUNT CHARGES
 
    A daily charge equal to an annual rate of 1.25% of average daily net assets
    is assessed to compensate WRL for assumption of mortality and expense risks
    and administrative services in connection with issuance and administration
    of the Contracts. This charge (not assessed at the individual contract
    level) effectively reduces the value of a unit outstanding during the year.
 
NOTE 3 - DIVIDENDS AND DISTRIBUTIONS
 
     Dividends of the Portfolios are declared and reinvested semiannually, while
capital gain distributions are declared and reinvested annually. Dividends and
distributions of the Fund are generally paid to and reinvested by the Annuity
Account the next business day after declaration.
