Bond Market Index Account
Objective:
The Account seeks to provide current income.
Fees and Expenses of the Account
This table describes the fees and expenses that you may pay if you buy and hold
shares of the Account. These fees and expenses do not reflect the fees and
expenses of any variable insurance contract that may invest in the Account and
would be higher if they did.
Annual Account Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Example
This Example is intended to help you compare the cost of investing in the
Account with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Account for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Account's operating expenses remain the same. If separate account expenses and
contract level expenses were included, expenses would be higher. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

Portfolio Turnover
The Account pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs. These costs, which are not reflected in
annual Account operating expenses or in the example, affect the Account's
performance. This is a new Account and does not yet have a portfolio turnover
rate to disclose.
Principal Investment Strategies
Under normal circumstances, the Account invests at least 80% of its net assets
in debt securities held by the Barclays Capital U.S. Aggregate Bond Index (the
"Index") at the time of purchase. The Index is composed of investment grade,
fixed rate debt issues, including government, corporate, asset-backed, and
mortgage-backed securities, with maturities of one year or more. The Account
employs a passive investment approach designed to attempt to track the
performance of the Index. The Account may actively trade portfolio securities.
Under normal circumstances, the Account maintains an average portfolio duration
that is in line with the duration of the Barclays Capital U.S. Aggregate Bond
Index, which as of December 31, 2011 was 5.01 years.
Principal Risks
The Account may be an appropriate investment for investors interested in
investing in a fixed-income mutual fund and preferring a passive, rather than
active, management style.

The value of your investment in the Account changes with the value of the
Account's investments. Many factors affect that value, and it is possible to
lose money by investing in the Account. An investment in the Account is not a
deposit of a bank and is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. The principal risks of
investing in the Account, in alphabetical order, are:

Active Trading Risk. Actively trading portfolio securities may accelerate
realization of taxable gains and losses, lower fund performance and may result
in high portfolio turnover rates and increased brokerage costs.
  
Fixed-Income Securities Risk. Fixed-income securities are subject to interest
rate risk and credit quality risk. The market value of fixed-income securities
generally declines when interest rates rise, and an issuer of fixed-income
securities could default on its payment obligations.

Index Fund Investment Risk. More likely than not, an index fund will not provide
investment performance that matches the index performance due to cashflows and
the fees and expenses of the fund.

Portfolio Duration Risk. Portfolio duration is a measure of the expected life of
a fixed-income security and its sensitivity to changes in interest rates. The
longer a fund's average portfolio duration, the more sensitive the fund will be
to changes in interest rates.

Prepayment Risk. Unscheduled prepayments on mortgage-backed and asset-backed
securities may have to be reinvested at lower rates. A reduction in prepayments
may increase the effective maturities of these securities, exposing them to the
risk of decline in market value over time (extension risk).

Real Estate Securities Risk. Real estate securities are subject to the risks
associated with direct ownership of real estate, including declines in value,
adverse economic conditions, increases in expenses, regulatory changes and
environmental problems.

Risk of Being an Underlying Fund. An underlying fund of a fund of funds may
experience relatively large redemptions or investments as the fund of funds
periodically reallocates or rebalances its assets. These transactions may cause
the underlying fund to sell portfolio securities to meet such redemptions, or to
invest cash from such investments, at times it would not otherwise do so, and
may as a result increase transaction costs and adversely affect underlying fund
performance.

U.S. Government Securities Risk. Yields available from U.S. government
securities are generally lower than yields from many other fixed-income
securities.

U.S. Government Sponsored Securities Risk. Securities issued by U.S.
government-sponsored or -chartered enterprises such as the Federal Home Loan
Mortgage Corporation, the Federal National Mortgage Association, and the Federal
Home Loan Banks are not issued or guaranteed by the U.S. Treasury.
Performance
No performance is shown because the Account has not yet had a calendar year of
performance. The Account's performance will be benchmarked against the Barclays
Capital U.S. Aggregate Bond Index.
