SA American Century Inflation Protection Portfolio Investment Risks - SA American Century Inflation Protection Portfolio
Mar. 31, 2025
Bonds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Bonds Risk. The Portfolio invests significantly in bonds. As with any fund that invests significantly in bonds, the value of your investment in the Portfolio may go up or down in response to changes in interest rates or defaults (or even the potential for future default) by bond issuers. To the extent the Portfolio is invested in bonds, movements in the bond market generally may affect its performance. In addition, individual bonds selected for the Portfolio may underperform the market generally. Fixed income securities may be subject to volatility due to changes in interest rates.
Inflation Indexed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Inflation-Indexed Securities Risk. Inflation-indexed securities are debt instruments whose principal is indexed to an official or designated measure of inflation, such as the Consumer Price Index in the United States. Inflation-indexed securities issued by a foreign government or foreign corporation are adjusted to reflect a comparable inflation index, calculated by that government. Inflation-indexed securities are sensitive to changes in the real interest rate, which is the nominal interest rate minus the expected rate of inflation. The price of an inflation-indexed security will increase if real interest rates decline, and decrease if real interest rates increase. If the interest rate rises for reasons other than inflation, the value of such instruments can be negatively impacted. Interest income will vary depending on changes to the principal amount of the security. For U.S. tax purposes, both interest payments and inflation adjustments to principal are treated as interest income subject to taxation when received or accrued, and inflation adjustments to principal are subject to taxation when the adjustment is made and not when the instrument matures.Repayment of the original principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-protected bonds (“TIPS”), even during a period of deflation. However, the current market value of a fixed income security is not guaranteed, and will fluctuate. Inflation-indexed securities, other than TIPS, may not provide a similar guarantee and may be supported only by the credit of the issuing entity. If a guarantee of principal is not provided, the adjusted principal value of the fixed income security repaid at maturity may be less than the original principal.Inflation-indexed securities issued by corporations may be similar to TIPS, but are subject to the risk of the corporation’s inability to meet principal and interest payments on the obligation and may also be subject to price volatility due to such factors as interest rate sensitivity, market perception of the credit-worthiness of the issuer and general market liquidity. There are many different types of corporate bonds, and each bond issue has specific terms.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk. Fixed income securities may be subject to volatility due to changes in interest rates. The value of fixed-income securities may decline when interest rates go up or increase when interest rates go down. The interest earned on fixed-income securities may decline when interest rates go down or increase when interest rates go up. Duration is a measure of interest rate risk that indicates how price-sensitive a bond is to changes in interest rates. Longer-term and lower coupon bonds tend to be more sensitive to changes in interest rates. For example, a bond with a duration of three years will decrease in value by approximately 3% if interest rates increase by 1%. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility, and could negatively impact the Portfolio’s performance. Any future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.
US Government Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] U.S. Government Obligations Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government and generally have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. A downgrade of the ratings of U.S. Government debt obligations, or concerns about the U.S. Government’s credit quality in general, could have a substantial negative effect on the U.S. and global economies. In addition, although the U.S. Government has honored its credit obligations, there remains a possibility that the U.S. could default on its obligations. The consequences of such an unprecedented event are impossible to predict, but it is likely that a default by the U.S. would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Portfolio’s investments.
Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Investment Risk. The Portfolio’s investments in the securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the Portfolio invests may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the Portfolio’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability and other conditions or events (including, for example, military confrontations, war, terrorism, sanctions, disease/virus, outbreaks and epidemics). Lack of relevant data and reliable public information may also affect the value of these securities. The risks of foreign investments are heightened when investing in issuers in emerging market countries.
Mortgage and Asset Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. The characteristics of these mortgage-backed and asset-backed securities differ from traditional fixed-income securities. Mortgage-backed securities are subject to prepayment risk (described below) and “extension risk.” Extension risk is the risk that, when interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities. These securities also are subject to risk of default on the underlying mortgage, particularly during periods of economic downturn.
CDOs Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] CDOs Risk. The risks of an investment in a CDO depend largely on the quality and type of the collateral securities and the class of the CDO in which the Portfolio invests. In addition to being subject to the risks of securitized instruments generally, CDOs are also subject to additional risks, such as illiquidity risk; the risk that distributions from collateral securities will not be adequate to make interest or other payments; and the risk that the collateral may default, decline in value or be downgraded.
Prepayment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Prepayment Risk. Prepayment risk is the possibility that the principal of the loans underlying mortgage-backed or other pass-through or fixed income securities may be prepaid at any time. As a general rule, prepayments increase during a period of falling interest rates and decrease during a period of rising interest rates. This can reduce the returns of a Portfolio because the Portfolio will have to reinvest that money at the lower prevailing interest rates. In periods of increasing interest rates, the occurrence of prepayments generally declines, with the effect that the securities subject to prepayment risk held by a Portfolio may exhibit price characteristics of longer-term debt securities.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. A derivative is any financial instrument whose value is based on, and determined by, another security, index, rate or benchmark (i.e., stock options, futures, caps, floors, etc.). To the extent a derivative contract is used to hedge another position in the Portfolio, the Portfolio will be exposed to the risks associated with hedging described below. To the extent an option, futures contract, swap, or other derivative is used with the goal of enhancing return, rather than as a hedge, the Portfolio will be directly exposed to the risks of the contract. Unfavorable changes in the value of the underlying security, index, rate or benchmark may cause sudden losses. Gains or losses from the Portfolio’s use of derivatives may be substantially greater than the amount of the Portfolio’s investment. Certain derivatives have the potential for unlimited loss. Derivatives are also associated with various other risks, including market risk, leverage risk, hedging risk, counterparty risk, valuation risk, regulatory risk, illiquidity risk and interest rate fluctuations risk. The primary risks associated with the Portfolio’s use of derivatives are market risk, counterparty risk and hedging risk.
Hedging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Hedging Risk. While hedging strategies can be very useful and inexpensive ways of reducing risk, they are sometimes ineffective due to unexpected changes in the market or exchange rates. Hedging also involves the risk that changes in the value of the related security will not match those of the instruments being hedged as expected, in which case any losses on the instruments being hedged may not be reduced. For gross currency hedges, there is an additional risk, to the extent that these transactions create exposure to currencies in which the Portfolio’s securities (or other positions) are not denominated.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Risk. Credit risk applies to most fixed income securities, but is generally not a factor for obligations backed by the “full faith and credit” of the U.S. Government. The Portfolio could lose money if the issuer of a fixed income security is unable or perceived to be unable to pay interest or to repay principal when it becomes due.
Settlement Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Settlement Risk. Investments purchased on an extended-settlement basis, such as when-issued, forward commitment or delayed-delivery transactions, involve a risk of loss if the value of the security to be purchased declines before the settlement date. Conversely, the sale of securities on an extended-settlement basis involves the risk that the value of the securities sold may increase before the settlement date.
Illiquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Illiquidity Risk. An illiquid investment is any investment that the Portfolio reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Illiquidity risk exists when particular investments are difficult to sell. Although most of the Portfolio’s investments must be liquid at the time of investment, investments may lack liquidity after purchase by the Portfolio, particularly during periods of market turmoil. When the Portfolio holds illiquid investments, its investments may be harder to value, especially in changing markets, and if the Portfolio is forced to sell these investments to meet redemption requests or for other cash needs, the Portfolio may suffer a loss. In addition, when there is illiquidity in the market for certain investments, the Portfolio, due to limitations on illiquid investments, may be unable to achieve its desired level of exposure to a certain sector. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities at or near their perceived value. In such a market, the value of such securities and the Portfolio’s share price may fall dramatically.
Inflation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Inflation Risk. The market price of the Portfolio’s debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Portfolio. Debt securities that pay a fixed rather than variable interest rate are especially vulnerable to inflation risk because interest rates on variable rate debt securities may increase as inflation increases. The Portfolio may be subject to inflation risk because no more than 55% of the Portfolio’s assets may be invested in securities issued by the same entity, such as the U.S. Treasury, due to the Internal Revenue Code provisions governing insurance product funds. Because the number of inflation-indexed debt securities issued by other entities is limited, the Portfolio may have a substantial position in non-inflation-indexed securities. To the extent that this is the case, that portion of the portfolio will not be automatically protected from inflation.
Affiliated Fund Rebalancing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Affiliated Fund Rebalancing Risk. The Portfolio may be an investment option for other mutual funds for which SunAmerica Asset Management, LLC (“SunAmerica”) serves as investment adviser that are managed as “funds of funds.” From time to time, the Portfolio may experience relatively large redemptions or investments due to the rebalancing of a fund of funds. In the event of such redemptions or investments, the Portfolio could be required to sell securities or to invest cash at a time when it is not advantageous to do so.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. The Portfolio is subject to management risk because it is an actively-managed investment portfolio. The Portfolio’s portfolio managers apply investment techniques and risk analyses in making investment decisions, but there can be no guarantee that these decisions or the individual securities selected by the portfolio managers will produce the desired results.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The Portfolio’s share price or the market as a whole can decline for many reasons or be adversely affected by a number of factors, including, without limitation: weakness in the broad market, a particular industry, or specific holdings; adverse social, political, regulatory or economic developments in the United States or abroad; changes in investor psychology; technological disruptions; heavy institutional selling; military confrontations, war, terrorism, sanctions and other armed conflicts; trade wars and similar conflicts; disease/virus outbreaks and epidemics; recessions; taxation and international tax treaties; currency, interest rates and price fluctuations; and other conditions or events. In addition, the adviser’s or a subadviser’s assessment of securities held in the Portfolio may prove incorrect, resulting in losses or poor performance even in a rising market.
Issuer Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Issuer Risk. The value of a security may decline for a number of reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] If the value of the assets of the Portfolio goes down, you could lose money.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] Shares of the Portfolio are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation.
