The Invesco American Franchise and Invesco V.I. Core Equity subaccounts can invest up to 25% of its assets in foreign securities that involve risks not associated with investing solely in the United States.

The LargeCap S&P 500 Index Subaccount employs a "passive management"-or indexing-investment approach designed to track the performance of the Standard & Poor's 500 Index, a widely recognized benchmark of U.S. stock market performance that is dominated by the stocks of large U.S. companies. The Portfolio attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

The LargeCap S&P 500 Index Subaccount is invested in the stocks of the index it tracks. Performance of indexes reflects the unmanaged result for the market segment the selected stocks represent. There is no assurance an index based investment option will match the performance of the index tracked.

The Principal Variable Contracts LifeTime Accounts indirectly bear their pro rata share of the management fees incurred by the underlying funds in which this fund invests. Based on the asset allocation of the funds outlined in the prospectus dated May 1, 2021, the weighted average operating expenses of the underlying funds are: Principal LifeTime Strategic Income, 0.46%; Principal LifeTime 2010, 0.48%; Principal LifeTime 2020, 0.52%; Principal LifeTime 2030, 0.57%; Principal LifeTime 2040, 0.62%; Principal LifeTime 2050, 0.65%; Principal LifeTime 2060, 0.66%.

The Principal LifeTime Accounts, which are target-date accounts, invest in underlying Principal Funds. Each Principal LifeTime Account is managed toward a particular target (retirement) date, or the approximate date the participant or investor starts withdrawing money. As each Principal LifeTime Account approaches its target date, the investment mix becomes more conservative by increasing exposure to generally more conservative investment options and reducing exposure to typically more aggressive investment options. The asset allocation for each Principal LifeTime Account is regularly re-adjusted within a timeframe that extends 10-15 years beyond the target date, at which point it reaches its most conservative allocation. Princiapl LifeTime Accounts assume the value of the investor's account will be withdrawn gradually during retirement. Neither the principal nor the underlying assets of the Principal LifeTime Accounts are guaranteed at any time, including the target date. Investment risk remains at all times.

Please note, while floating rate securities may offer the potential for lower interest rate sensitivity, funds such as the Guggenheim Floating Rate Strategies, which invests in floating rate securities are subject to significant credit and valuation risk associated with the underlying loans in the portfolio.

The Guggenheim Investments Global Managed Futures Strategy's investment objective and principal investment strategies changed on July 11, 2011 and September 27, 2012. Prior to September 27, 2012, the Fund sought to achieve positive absolute returns using an investment methodology based primarily on the S&P DTI's systematic rules-based trend-following strategy. Prior to July 11, 2011, the Fund sought to provide investment results that matched, before fees and expenses, the performance of the S&P DTI. Therefore, the performance and average annual total returns shown for periods prior to July 11, 2011 may have differed had the Funds's current investment objective and principal investment strategy been in effect during those periods.

Effective 10/30/2013 the Guggenheim Investments Long Short Equity name was changed to Variable Insurance Long Short Equity Fund from Variable Insurance U.S. Long Short Momentum Fund and certain changes were made to the Fund's principal investment strategies. Prior to 5/28/2010, the fund did not employ a hedging model to achieve its objective; therefore, the performance and average annual total returns shown for periods prior to 5/28/2010 may have differed had the Fund's current investment strategy been in effect during those periods.

Guggenheim Investments Multi-Hedge Strategies -- "Short Sales Dividend and Interest Expense" is not a fee charged to the shareholder, and it is generally offset by an unrealized capital gain within the fund. "Short Sales Dividend and Interest Expense" is incurred when the Fund short sells a security to gain the inverse exposure necessary to meet its investment objective. The Fund must pay out the dividend rate on an equity security, the coupon rate of a fixed income security, and interest expense associated with either, to the lender and records these as an expense of the Fund and reflects these expenses in its financial statements. However, any such dividend or interest expense on a security sold short generally has the effect of reducing the market value of the shorted security-thus increasing the Fund's unrealized gain or reducing the Fund's unrealized loss on its short sale transaction. "Short Sales Dividend and Interest Expense" is not a fee charged to the shareholder by the advisor or other service provider. Rather it is more similar to the transaction costs or capital expenditures associated with the day-to-day management of any mutual fund. See prospectus for more information.

For the Columbia Limited Duration Credit and the BlackRock 60/40 Target Allocation ETF Divisions the bond values fluctuate in price so the value of your investment can go down depending on market conditions. Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments.

For the BlackRock 60/40 Target Allocation ETF the International investing involves special risks including, but not limited to currency fluctuations, illiquidity and volatility. These risks may be heightened for investments in emerging markets. Derivatives entail risks relating to liquidity, leverage and credit that may reduce returns and increase volatility.

Due to the EQ Advisors Trust 1290 VT Socially Responsible subaccount's social policy, it may experience greater volatility than investment options with a broader investment strategy.

EQ Advisors Trust 1290 VT SmartBeat Equity - A portfolio comprised of stocks intended to reduce exposure to uncompensated risk may not necessarily be less sensitive to a change in the broad market price level and may not accurately estimate the risk/return outcome of stocks. Portfolio investments may exhibit higher volatility than expected or underperform the markets. The portfolio's strategy may result in the portfolio underperforming the general securities markets, particularly during periods of strong positive market performance.

EQ Advisors Trust 1290 VT Convertible Securities - The value of a convertible security fluctuates in relation to changes in interest rates and the credit quality of the issuer and, in addition, fluctuates in relation to the underlying common stock. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer-specific risks that apply to the underlying common stock. A convertible security may be subject to redemption at the option of the issuer at a price established in the convertible security's governing instrument, which may be less than the current market price of the security.
