HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
HARTFORD LIFE AND ANNUITY INSURANCE COMPANY SEPARATE ACCOUNT SIX
SUPPLEMENT DATED NOVEMBER 12, 1998
TO
PROSPECTUS DATED MAY 1, 1998
On or about November 10, 1998, Hartford Life and Annuity Insurance Company
("Hartford") and several other applicants filed an application with the
Securities and Exchange Commission seeking an order approving the substitution
of shares of certain investment portfolios of One Group Investment Trust ("One
Group Trust") for shares of certain investment portfolios of Pegasus Variable
Funds ("Pegasus Trust") currently held by various subaccounts of Hartford Life
and Annuity Insurance Company Separate Account Six (the "Account"). To the
extent required by law, approvals of such substitutions will also be obtained
from the state insurance regulators in certain jurisdictions. The effect of the
proposed share substitutions would be to replace certain portfolios of Pegasus
Trust with those of One Group Trust as investment options under the Contracts as
described in your May 1, 1998 prospectus.
More particularly, Hartford proposes to substitute: (1) shares of One Group
Trust's Bond Fund for shares of Pegasus Trust's Bond Fund, (2) shares of One
Group Trust's Value Growth Fund for shares of Pegasus Trust's Growth and Value
Fund, (3) shares of One Group Trust's Mid Cap Opportunities Fund for shares of
Pegasus Trust's Mid Cap Opportunity Fund, (4) shares of One Group Trust's Large
Company Growth Fund for shares of Pegasus Trust's Growth Fund, and (5) shares of
One Group Trust's Mid-Cap Value Fund for shares of Pegasus Trust's Intrinsic
Value Fund.
The investment objectives of One Group Trust's Bond Fund, Value Growth Fund,
Mid-Cap Opportunities Fund, Large Company Growth Fund and Mid-Cap Value Fund are
summarized below.
One Group Trust's Value Growth Fund seeks long-term capital growth and
growth of income and secondarily, a moderate level of current income. The
Fund seeks to achieve its objectives by investing primarily equity
securities. For this purpose, equity securities include common stocks and
debt securities and preferred stock that are convertible into common stock.
The Fund invests in securities of overlooked or undervalued companies that
have the potential to produce above-average earnings growth over time. The
Fund follows a multi-style strategy in that it invests in securities of both
value and growth oriented companies of varying levels of capitalization.
One Group Trust's Large Company Growth Fund seeks long-term capital
appreciation and growth of income by investing primarily in equity
securities (as defined for the Value Growth Fund) of large well-established
companies. The weighted average market capitalization of such companies
normally exceeds the median market capitalization of the Standard & Poor's
500 Composite Stock Price Index. The Fund normally invests at least 65% of
its total assets in such equity securities. The remainder of the Fund's
total assets are invested in nonconvertible fixed-income securities, options
and future contracts, repurchase agreements, and securities issued by the
U.S. government and its agencies and instrumentalities.
One Group Trust's Bond Fund seeks to earn a high level of current income and
total return by investing primarily in a diversified portfolio of debt
securities of various maturities. At least 65% of the Fund's total assets is
invested in bonds and at least 80% in debt securities of all types with
varying maturities. Generally debt securities acquired by the Fund are rated
investment grade but the Fund may invest up to 5% of its net assets in debt
securities rated below investment grade. The Fund also may invest in
convertible securities, preferred stock and loan participations. The fund
normally maintains a weighted average maturity of between six to twelve
years, although it may shorten this maturity for temporary defensive
purposes.
One Group Trust's Mid Cap Opportunities Fund seeks long term capital growth
by investing primarily in equity securities (as defined for the Value Growth
Fund) of companies with market capitalizations of between $500 million and
$5 billion. Normally the Fund invests at least 80% of its total assets in
common and preferred stock, rights, warrants, securities convertible into
common stock, and other equity securities. The Fund may invest up to 25% of
its total assets in equity securities of foreign issuers and up to 20% of
its total assets in investment grade debt securities, U.S. government
securities, cash and cash equivalents. The Fund may hold up to 5% of its
total assets in convertible debt securities rated lower than investment
grade.
One Group Trust's Mid Cap Value Fund seeks capital appreciation with a
secondary goal of obtaining income by investing primarily in equity
securities (as defined for the Value Growth Fund). Under normal market
conditions, at least 80% of the Fund's total assets are invested in equity
securities having market capitalizations of $500 million to $5 billion.
Generally, the Fund invests in equity securities of companies with
below-average price/earnings and price/book value ratios. The Fund also
considers a company's financial soundness and earnings prospects. The Fund
generally will sell a security if its investment adviser considers that the
issuer's fundamental business prospects are declining or its ability to pay
dividends is impaired.
