C000238594 Investment Objective and Strategy
U.S. LargeCap S&P 500 Index Buffer October Account describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Principal Variable Contracts Funds Inc.
Investment objective
The Fund seeks to provide investors with returns (before fees and expenses) based on the S&P 500 Price Return Index (the Index), while seeking to provide a buffer against the first 10% (prior to taking into account any fees and expenses of the Fund) of Index losses, over a twelve-month period beginning on October 1 and ending on September30.
Principal investment strategy
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in exchange-traded funds (ETFs) and options that reference the S&P 500 Price Return Index (the Index). The Index represents U.S. equities with risk/return characteristics of the large cap universe. As of March 31, 2026, the market capitalization range of the Index was between approximately $5.3 billion and $4.2 trillion. The Index is distinct from the S&P 500 Total Return Index in that it only tracks the performance of the stock prices of the companies included in the Index and does not include returns from dividends paid by the companies included in the Index. The Fund's strategies may result in the active and frequent trading of the Fund's portfolio securities.
The Funds investment advisor, Principal Global Investors, LLC (PGI), employs a defined outcome strategy that uses options to seek to achieve exposure to the Index while mitigating the first 10% decline in the Index (the Buffer) over a 12-month period beginning on the first day of each October (the Specified Date). The one-year period following the Specified Date is referred to as the Outcome Period. Subject to certain limitations described in more detail below, the Fund generally seeks to maintain net costs from its use of options approximately equal to its anticipated receipt of dividends as determined at the beginning of the Outcome Period. Intra-period cash flows are managed to target and maintain the return pattern determined at the beginning of the Outcome Period. Accordingly, changes in the amounts of dividends paid by companies underlying the Index and changes in the value of companies underlying the Index can cause performance to be lower than the performance of the Index.
At the beginning of each Outcome Period, the Fund will purchase ETFs and call options that reference the Index and a put option at-the-money for the purpose of providing downside protection. The Fund will sell (write) put options on the Index or an ETF that tracks the Index with a strike price approximately 10% lower than the closing value of the Index or an ETF that tracks the Index at the beginning of the Outcome Period. The Fund will sell (write) call options on the Index or an ETF that tracks the Index with a strike price approximately 10% higher than the closing value of the Index or an ETF that tracks the Index at the beginning of the Outcome Period. As the seller of these options, the Fund receives a premium from the buyer of the options. The Fund expects to write the call options on one or more of the ETFs owned by the Fund or the Index to the extent necessary to maintain its net costs from the purchase and sale of options approximately equal to its anticipated receipt of dividends, as determined at the beginning of the Outcome Period, but it will do so only to the extent that the written call options on each respective ETF or the Index have an aggregate notional value less than or equal to the market value of the respective ETF or the Index owned by the Fund.
The Fund will generally not seek to offset the costs of call options purchased. The Funds returns are generally expected to appreciate to a similar extent as the Index for the first 10% of the Index gains. The prices of the call options and put options sold and purchased by the Fund, in addition to the Funds direct investments in underlying ETFs, will determine the Funds exposure to the Index during the Outcome Period. Intra-period cash flows are managed to target and maintain the return pattern determined at the beginning of the Outcome Period. An option gives the purchaser of the option the right to purchase (for a call option) or sell (for a put option) the underlying asset (or deliver cash equal to the value of an underlying index) at a specified price (the strike price). If the underlying asset declines in value, the value of a put option will generally increase (and the value of a call option will generally decrease and may end up worthless), and in the event the underlying asset appreciates in value, the value of a put option will generally decrease and may end up worthless (and the value of a call option will generally increase).
Due to the cost of the options used by the Fund, the correlation of the Funds performance to that of the Index is expected to be less than if the Fund invested directly in the Index without using options, and could be substantially less. This means that if the Index experiences gains for an Outcome Period, the Fund may not realize gains to the same extent, as illustrated in the second hypothetical graphical illustration below. The Funds strategy is to seek to protect investors from a decline of up to 10% in the performance of the Index over the Outcome Period. The Fund is not designed to protect against declines of more than 10% in the level of the Index, and there can be no guarantee that the Fund will be successful in implementing its strategy to buffer against the first 10% of Index losses.
The Fund, and therefore investors, will bear all losses exceeding 10%. In addition, because the outcome is calculated before taking into account the Funds expenses, Fund performance over an Outcome Period will be exposed to losses beyond the Buffer in the amount of such Fund expenses. The Fund may underperform the Index due to the cost of the Buffer protection. The Fund will invest in exchange-traded FLexible EXchange Options (FLEX Options), which are customized exchange-traded option contracts available through the Chicago Board Option Exchange (Cboe) that are guaranteed for settlement by The Options Clearing Corporation (OCC). FLEX Options provide investors with the ability to customize exercise prices, exercise styles, and expiration dates. All FLEX Options in the Fund are European-style options (i.e., they can only be exercised at the expiration date of the option) based on the Index or an ETF that tracks the Index and have an expiration date that is the last day of the Outcome Period.
The hypothetical graphical illustrations provided below are designed to illustrate the hypothetical outcomes of the Buffer strategy based upon hypothetical performance of the Index for a shareholder that holds shares for the entirety of an Outcome Period. The illustrations assume that the Fund will write call options with an aggregate notional amount equal to 50% of the market value of the ETFs and purchased call options. There is no guarantee that the Fund will be successful in its attempt to provide such outcomes for an Outcome Period, and the actual aggregate notional amount of written call options could be significantly different depending upon changes in the amounts of dividends paid by companies underlying the Index, changes in the value of companies underlying the index, and the relative prices of the options used by the Fund.
The returns that the Fund seeks to provide do not include the costs associated with purchasing shares of the Fund and the expenses incurred by the Fund. The Buffer is designed to have its full effect only for investors who continually hold Fund shares for an entire Outcome Period. The Fund is designed to seek to achieve the results described above for investments made on the first day of the Outcome Period and held until the last day of the Outcome Period. Investments made on any other day may differ significantly, positively or negatively, from the results described above. The Funds operations are intended to be continuous. It will not terminate and distribute its assets at the conclusion of each Outcome Period. On the Specified Date, another Outcome Period will commence, and the Fund will invest in a new set of FLEX Options.
The Fund will not concentrate (i.e., invest more than 25% of its assets) its investments in a particular industry except to the extent the Index is so concentrated. As of March 31, 2026, the Index was not concentrated in any industry.
