Holding Characteristics

Portfolio characteristic data are based on unaudited net assets.


The portfolio is actively managed, and current holdings may be different.


Average Effective Maturity: Average effective maturity is a weighted average of maturity of the bonds held in a portfolio, taking into account any prepayments, puts, and adjustable coupons which may shorten the maturity. Longer-maturity funds are generally considered more interest-rate sensitive than shorter maturity funds.

Important Performance Information Disclosures

The information contained in this section pertains to the Funds which comprise the MFS® Variable Insurance Trust. Shares of each applicable Fund are offered at NAV and are available solely as an underlying investment option for variable life insurance and variable annuity products issued or administered by life insurance companies. These insurance companies actually own the shares of the applicable Funds. You do not buy, sell or exchange shares of the Funds--you choose investment options through your variable annuity contract or variable life insurance policy. The insurance company then invests in the shares of the Fund according to the investment options you've chosen. Returns do not reflect fees and expenses of any variable annuity contract or variable life insurance policy, and would be lower if they did. Please refer to specific performance reporting from the issuing insurance company for returns that reflect such charges.

Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the series' performance results would be less favorable. All results assume the reinvestment of dividends and capital gains. The performance is as of the date shown; it may not include the series' entire investment portfolio and is subject to change.

Initial Class shares have no sales charge.

e Gross Expense Ratio: The Gross Expense Ratio is the fund's total operating expense ratio from the fund's most recent prospectus.

e Net Expense Ratio: The Net Expense Ratio reflects the reduction of expenses from fee waivers and reimbursements. Elimination of these reductions will result in higher expenses and lower performance. These reductions will continue until at least the Earliest Waiver End Date.

The returns for the series shown do not reflect the deduction of expenses associated with variable products, such as mortality and expense risk charges, separate account charges, and sales charges imposed by insurance company separate accounts. Such expenses would reduce the overall returns shown. Please refer to the variable product's annual report for performance that reflects the deduction of the fees and charges imposed by insurance company separate accounts.

Withdrawals of earnings and other taxable amounts are subject to income tax and, if made prior to age 59 ½, may be subject to an additional 10% federal tax penalty. Early withdrawals reduce the death benefit.

No representation is made, and no assurance can be given, that any investment's results will be comparable to the investment results of any other product with similar investment objectives and policies, including products with the same investment professional or manager. Differences in portfolio size, investments held, contract and portfolio expenses, and other factors can be expected to affect performance.

Definitions

Alpha: Alpha is a measure of the portfolio's risk-adjusted performance. When compared to the portfolio's beta, a positive alpha indicates better-than-expected portfolio performance and a negative alpha worse-than-expected portfolio performance.

Beta: Beta is a measure of the volatility of a portfolio relative to the overall market. A beta less than 1.0 indicates lower risk than the market; a beta greater than 1.0 indicates higher risk than the market. It is most reliable as a risk measure when the return fluctuations of the portfolio are highly correlated with the return fluctuations of the index chosen to represent the market.

Information Ratio: Information ratio is a measure of consistency in excess return. The annualized excess return over a benchmark divided by the annualized standard deviation of excess return.

R-squared: R2 represents the percentage of the portfolio's movements that can be explained by the general movements of the market. Index portfolios will tend to have values very close to 100.

Sharpe Ratio: The Sharpe Ratio is a risk-adjusted measure calculated to determine reward per unit of risk. It uses a standard deviation and excess return. The higher the Sharpe Ratio, the better the portfolio's historical risk-adjusted performance.

Standard Deviation: Standard deviation is an indicator of the portfolio's total return volatility, which is based on a minimum of 36 monthly returns. The larger the portfolio's standard deviation, the greater the portfolio's volatility.

Tracking Error: Tracking error is the active risk of the portfolio that measures the dispersion of the portfolio's return minus the benchmark's annualized return.

Treynor Ratio: Treynor Ratio is a risk adjusted measure of performance. It is the ratio of the annualized excess return of the portfolio over the risk free rate for a given period divided by the Beta of the portfolio versus its benchmark for the same period. It measures the amount of excess return over the risk free rate earned per unit of systematic risk (beta) assumed.

Upside / Downside Capture %: The upside and downside capture is a measure of how well a manager was able to replicate or improve on phases of positive benchmark returns, and how badly the manager was affected by phases of negative benchmark returns. To calculate the up capture, we first form new series from the manager and benchmark series by dropping all time periods where the benchmark return is zero or negative. The up capture is then the quotient of the annualized return of the resulting manager series, divided by the annualized return of the resulting benchmark series. The down capture is calculated analogously.

Before purchasing any variable product, consider the objectives, risks, charges, and expenses associated with the underlying investment option(s) and those of the product itself. For a prospectus, or summary prospectus if available, containing this and other information, contact your investment or insurance professional. Read the prospectus carefully before you invest.
