Dear Contract Owner:
An unprecedented combination of generally positive factors has helped the U.S.
economy enjoy a sustained period of relative stability and moderate growth in
which thousands of new jobs have been created every month, inflation remains
under control, and the investment climate -- at least until now -- has been
favorable. For example, the increased use of technology and other productivity
enhancements, as well as corporate restructuring and global competition, is
improving companies' balance sheets and helping control inflation. Meanwhile,
borrowing by corporations and governments continues to decline, while consumer
confidence is increasing, although consumer debt levels are still uncomfortably
high. While some lenders are beginning to tighten standards to address this
problem, consumer debt and personal bankruptcies continue to rise. Because of
this, plus slight declines in other indicators such as average hourly wages and
the corporate purchasing-managers index, we do not expect the rapid pace of
growth seen in the first quarter of 1997 to continue. While second-quarter
growth has slowed dramatically, we do expect the second half of the year to pick
up once again with real (inflation-adjusted) growth centering around 2 1/2%.
We have been surprised by the strength of the U.S. equity market in the
first half of 1997. Much of this is the result of continuing gains in corporate
earnings. Even as the current recovery enters its seventh year, more and more
U.S. companies have been exceeding MFS analysts' earnings estimates. In the
first quarter of 1997, for example, two-thirds of all companies met or exceeded
MFS analysts' expectations, a trend that could be an important indicator of the
U.S. equity market's future direction. However, while the near-term outlook for
profits is generally favorable, we believe equity valuations have risen to a
point where a cautious investment approach seems warranted.
In the fixed-income markets, we have been encouraged by the Federal Reserve
Board's decision to not raise short-term interest rates at its July meeting. But
we cannot rule out the possibility of future monetary tightening in the second
half of the year if, as we now expect, the economy strengthens in the second
half of 1997. Therefore, our risk/reward outlook for the fixed-income markets is
neutral, and we believe that fixed-income investors should think in terms of
earning the coupon income from their investments rather than seeking possible
gains from price appreciation.
Comments from the head of the MFS Total Return Series Team are presented on
the next page. We appreciate your support and welcome any questions or comments
you may have.

MFS TOTAL RETURN SERIES
For the six months ended June 30, 1997, the Series provided a total return of
11.38% (including the reinvestment of distributions). This compares to a 20.60%
return for the Standard & Poor's 500 Composite Index (the S&P 500), a popular,
unmanaged index of common stock total return performance, and to a 2.74% return
for the Lehman Brothers Government Corporate Bond Index, an unmanaged,
market-value-weighted index of U.S. Treasury and government-agency securities,
excluding mortgage-backed securities.
The pace of economic activity in the second quarter has slowed from the 5.9%
annual rate posted in the first quarter of 1997. However, the U.S. economy
remains firm, which should support corporate earnings growth. The rate of
unemployment remains low, ending June at 5% and, while inflation has not been a
problem in recent years, we are keeping a close eye out for any signs of an
increase.
We believe the continuing strength of the dollar should serve to dampen the
U.S. economy in the near future. Conversely, we feel that the rise in the
dollar's value over the past year should help improve the competitiveness of
many foreign corporations, which could serve to accelerate foreign economies.
Still, investors remain bullish on corporate America, and stock prices have
risen throughout most of the period.
Our allocations remain conservative. At the end of June, 58% of the
portfolio was invested in stocks, preferred stocks, and convertible bonds. We
generally consider a 60% stock weighting neutral and anything over 65%
aggressive. We have been maintaining this conservative equity posture for some
time because, in our view, equities are not cheap by historical standards.
Specifically, the yield on the S&P 500 is under 2%, which is close to an
all-time low.
In selecting stocks for the Series, we prefer to own companies in which we
anticipate stable earnings growth. We also like to pay a price for these
securities (as measured by price-to-earnings ratios, dividend yields, and
price-to-book ratios) that is below the average for the market. We have found
these characteristics in the financial services and industrial goods and
services sectors, both of which did well during the period. Both sectors have
reported solid earnings, while consolidation activity continues to boost values
of financial services stocks.
We continue to be underweighted in the technology and the consumer
nondurable goods sectors. While we feel there are many fine companies in both of
these sectors, we do not think their valuations have been compelling in recent
months.
The performance of aerospace and defense stocks has been disappointing, in
part because, after years of consolidation, the market is beginning to fear that
the industry is in for a period of slow growth. However, we still find this
sector attractive because we believe these companies can continue to produce
solid earnings over the long term. Another disappointment came in the utility
sector, where the pace of deregulation continues to pick up, bringing
uncertainty and placing lower values on the sector.
Looking ahead, we see a modest growth rate in the U.S. economy over the next
12 months. Over the near term, however, we believe the Federal Reserve Board
will keep a close watch on wage inflation and general economic activity and may
raise interest rates again should economic indicators suggest a
stronger-than-expected economy.
Our bond portfolio represents approximately 33% of the Series, with
two-thirds in corporates and one-third in Treasuries. The duration, or
interest-rate sensitivity, of the bond portfolio has been approximately 5.4
years over the period.
Given where equity valuations are today, we feel comfortable with our asset
allocation. However, should the stock market correct, we would be looking to buy
additional stocks.

PORTFOLIO MANAGERS' PROFILES
David M. Calabro, Vice President; Geoffrey L. Kurinsky, Senior Vice President;
Judith N. Lamb, Vice President; Lisa B. Nurme, Vice President; and Maura A.
Shaughnessy, Vice President, are the Series' portfolio managers. Mr. Calabro
is the head of this portfolio management team and a manager of the common
stock portion of the Series' portfolio. Mr. Calabro has been employed by MFS
since 1992. Mr. Kurinsky, the manager of the Series' fixed-income securities,
has been employed by MFS since 1987. Ms. Lamb, the manager of the Series'
convertible securities, has been employed by MFS since 1992. Ms. Nurme, a
manager of the common stock portion of the Series' portfolio, has been
employed by MFS since 1987. Ms. Shaughnessy, also a manager of the common
stock portion of the Series' portfolio, has been employed by MFS since 1991.
OBJECTIVES AND POLICIES
The Series' primary investment objective is to provide above-average income
consistent with the prudent employment of capital. Its secondary objective is to
provide a reasonable opportunity for growth of capital and income, since many
securities offering a better-than-average yield may also possess growth
potential.
Commencement of investment operations: January 3, 1995.

NOTES TO FINANCIAL STATEMENTS
(1) Business and Organization
MFS Total Return Series (the Series) is a diversified series of MFS(R) Variable
Insurance Trust (the Trust) which is comprised of the following 12 series:
MFS(R) Bond Series, MFS(R) Emerging Growth Series, MFS(R) Growth with Income
Series, MFS(R) High Income Series, MFS(R) Limited Maturity Series, MFS(R) Money
Market Series, MFS(R) Research Series, MFS(R) Strategic Fixed Income Series, MFS
Total Return Series, MFS(R) Utilities Series, MFS(R) Value Series, and MFS(R)
World Governments Series. The Trust is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended, as
an open-end management investment company.
The shareholders of each Series of the Trust are separate accounts of insurance
companies which offer variable annuity and/or life insurance products. As of
June 30, 1997, there were 24 shareholders in the Series.
(2) Significant Accounting Policies
General - The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Investments
in foreign securities are vulnerable to the effects of changes in the relative
values of the local currency and the U.S. dollar and to the effects of changes
in each country's legal, political, and economic environment.
Investment Valuations - Equity securities listed on securities exchanges or
reported through the NASDAQ system are reported at market value using last sale
prices. Unlisted equity securities or listed equity securities for which last
sale prices are not available are reported at market value using last quoted bid
prices. Debt securities (other than short-term obligations which mature in 60
days or less), including listed issues, are valued on the basis of valuations
furnished by dealers or by a pricing service with consideration to factors such
as institutional-size trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics, and other market
data, without exclusive reliance upon exchange or over-the-counter prices.
Short-term obligations, which mature in 60 days or less, are valued at amortized
cost, which approximates market value. Securities for which there are no such
quotations or valuations are valued at fair value as determined in good faith by
or at the direction of the Trustees.
Foreign Currency Translation - Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. Purchases and
sales of foreign investments, income, and expenses are converted into U.S.
dollars based upon currency exchange rates prevailing on the respective dates of
such transactions. Gains and losses attributable to foreign currency exchange
rates on sales of securities are recorded for financial statement purposes as
net realized gains and losses on investments. Gains and losses attributable to
foreign exchange rate movements on income and expenses are recorded for
financial statement purposes as foreign currency transaction gains and losses.
That portion of both realized and unrealized gains and losses on investments
that result from fluctuations in foreign currency exchange rates is not
separately disclosed.
Deferred Organization Expenses - Costs incurred by the Series in connection with
its organization have been deferred and are being amortized on a straight-line
basis over a five-year period beginning on the date of commencement of Series
operations.
Investment Transactions and Income - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
original issue discount are amortized or accreted for financial statement and
tax reporting purposes as required by federal income tax regulations. Dividend
income is recorded on the ex-dividend date for dividends received in cash.
Dividend and interest payments received in additional securities are recorded on
the ex-dividend or ex-interest date in an amount equal to the value of the
security on such date.
Fees Paid Indirectly - The Series' custody fee is calculated as a percentage of
the Series' average daily net assets. This fee is reduced according to an
expense offset arrangement with State Street Bank, the dividend disbursing
agent, which provides for partial reimbursement of custody fees based on a
formula developed to measure the value of cash deposited by the Series with the
custodian and with the dividend disbursing agent. This amount is shown as a
reduction of expenses on the Statement of Operations.
Tax Matters and Distributions - The Series' policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. The Series files a tax
return annually using tax accounting methods required under provisions of the
Code which may differ from generally accepted accounting principles, the basis
on which these financial statements are prepared. Accordingly, the amount of net
investment income and net realized gain reported on these financial statements
may differ from that reported on the Series' tax return and, consequently, the
character of distributions to shareholders reported in the financial highlights
may differ from that reported to shareholders on Form 1099-DIV. Distributions to
shareholders are recorded on the ex-dividend date. The Series distinguishes
between distributions on a tax basis and a financial reporting basis and
requires that only distributions in excess of tax basis earnings and profits are
reported in the financial statements as a tax return of capital. Differences in
the recognition or classification of income between the financial statements and
tax earnings and profits which result in temporary over-distributions for
financial statement purposes are classified as distributions in excess of net
investment income or accumulated net realized gains.
(3) Transactions with Affiliates
Investment Adviser - The Series has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate of
0.75% of average daily net assets. Under a temporary expense limitation
agreement with MFS, MFS has voluntarily agreed to pay all of the Series'
operating expenses, exclusive of management fees. The Series in turn will pay
MFS an expense reimbursement fee not greater than 0.25% of average daily net
assets. To the extent that the expense reimbursement fee exceeds the Series'
actual expenses, the excess will be applied to amounts paid by MFS in prior
years. At June 30, 1997, the aggregate unreimbursed expenses owed to MFS by the
Series amounted to $84,143 after net reimbursement in the current period.
Administrator - Effective March 1, 1997, the Series has an administrative
services agreement with MFS to provide the Series with certain financial, legal
and other administrative services. As a partial reimbursement for the cost of
providing these services, the Series pays MFS an administrative fee up to 0.015%
per annum of the Series average daily net assets, provided that the
administrative fee is not assessed on Series assets that exceed $3 billion.
The Series pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Series, all of whom receive
remuneration for their services to the Series from MFS. Certain officers and
Trustees of the Series are officers or directors of MFS and MFS Service Center,
Inc. (MFSC).
Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as a
percentage of the series' average daily net assets at an effective annual rate
of up to 0.035%.
(4) Portfolio Securities
Purchases and sales of investments, other than purchased option transactions and
short-term obligations, were as follows:

line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made to temporarily finance the repurchase of
Series shares. Interest is charged to each fund, based on its borrowings, at a
rate equal to the bank's base rate. In addition, a commitment fee, based on the
average daily unused portion of the line of credit, is allocated among the
participating funds at the end of each quarter. The commitment fee allocated to

INDEPENDENT AUDITORS' REPORT
To the Trustees of MFS Variable Insurance Trust and Shareholders of MFS Total
Return Series:
We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of MFS Total Return Series (the Series) (one of
the series constituting the MFS Variable Insurance Trust) as of June 30, 1997,
the related statement of operations for the six months then ended, the
statements of changes in net assets for the six months then ended and for the
year ended December 31, 1996, and financial highlights for the six months then
ended, the year ended December 31, 1996, and the period from January 3, 1995
(the commencement of investment operations) to December 31, 1995. These
financial statements and financial highlights are the responsibility of the
Series' 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 the securities owned at June
30, 1997 by correspondence with the custodian and brokers; where replies were
not received from brokers, we performed other auditing procedures. 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MFS Total Return
Series at June 30, 1997, the results of its operations, the changes in its net
assets, and its financial highlights for the respective periods in conformity
with generally accepted accounting principles.
