Launch of State Street® SPDR® Portfolio Ultra Short T-Bill ETF (SPTU) Provides Investors with Low-Cost Access to Treasurys that Mature in a Year or Less
State Street Investment Management today announced the expansion of its low-cost State Street® SPDR® Portfolio ETF Suite with the launch of the State Street SPDR Portfolio Ultra Short T-Bill ETF (SPTU). The new fund offers investors access to the shorter end of the yield curve by providing exposure to US Treasury bills that have a remaining maturity greater than or equal to 1 month and less than 12 months. Priced at just five basis points, SPTU is one of the lowest-cost ETFs in the ultra-short Treasury bond fund category.1
With the addition of the State Street SPDR Portfolio Ultra Short T-Bill ETF, which seeks to track the performance of the ICE BofA US Treasury Bill Index, the State Street SPDR Portfolio US Treasury suite provides investors with exposure to a full spectrum of maturities across the yield curve. Funds in the low-cost State Street SPDR Portfolio Treasury suite include SPDR Portfolio Short Term Treasury ETF (SPTS), SPDR Portfolio Intermediate Term Treasury ETF (SPTI), SPDR Portfolio Long Term Treasury ETF (SPTL), and SPDR Portfolio Treasury ETF (SPTB).
“Whether it’s in response to changes in Federal Reserve policy, inflation expectations, economic forecasts, or liquidity needs, ETFs allow investors to fine-tune their fixed income allocations,” said Anna Paglia, chief business officer for State Street Investment Management. “The launch of SPTU provides clients with a low-cost, ultra-short term Treasury option designed to help them meet their income generation and risk mitigation goals and may serve as a flexible and efficient funding solution for some institutional investors, including as a potential collateral tool for certain derivatives market participants.”
Introduced in 2017 and with offerings priced as low as two basis points, the State Street SPDR Portfolio ETF suite is designed to provide investors with greater choice in low-cost ETFs. The suite provides exposure to US equity, international equity, and fixed income asset classes designed to help investors build a diversified core portfolio of stocks and bonds while keeping more of what they earn. Widely embraced by investors, State Street SPDR Portfolio ETFs have amassed more than $323 billion in assets.2
SPTU may serve as a cost-effective collateral tool for market participants. The fund is intended to qualify as a permitted investment by futures commission merchants (FCMs) and derivatives clearing organizations (DCOs) under CFTC Reg 1.25, as amended, and as eligible margin collateral for uncleared swaps transactions.3,4

Important Risk Information
Investing involves risk including the risk of loss of principal.
ETFs trade like stocks, are subject to investment risk, fluctuate in market value and may trade at prices above or below the ETFs net asset value. Brokerage commissions and ETF expenses will reduce returns.
While the shares of ETFs are tradable on secondary markets, they may not readily trade in all market conditions and may trade at significant discounts in periods of market stress.
The whole or any part of this work may not be reproduced, copied or transmitted or any of its contents disclosed to third parties without SSGA’s express written consent.

Third party data providers make no warranties or representations of any kind relating to the accuracy, completeness or timeliness of the data and have no liability for damages of any kind relating to the use of such data.
All information is from SSGA unless otherwise noted and has been obtained from sources believed to be reliable, but its accuracy is not guaranteed. There is no representation or warranty as to the current accuracy, reliability or completeness of, nor liability for, decisions based on such information and it should not be relied on as such.
The information provided does not constitute investment advice and it should not be relied on as such. It should not be considered a solicitation to buy or an offer to sell a security. It does not take into account any investor's particular investment objectives, strategies, tax status or investment horizon. You should consult your tax and financial advisor.
Market Risk: The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investing in markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.
Bonds generally present less short-term risk and volatility than stocks, but contain interest rate risk (as interest rates rise, bond prices usually fall); issuer default risk; issuer credit risk; liquidity risk; and inflation risk. These effects are usually pronounced for longer-term securities. Any fixed income security sold or redeemed prior to maturity may be subject to a substantial gain or loss.
US Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline.
Passively managed funds invest by sampling the index, holding a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. This may cause the fund to experience tracking errors relative to performance of the index. While the shares of ETFs are tradable on secondary markets, they may not readily trade in all market conditions and may trade at significant discounts in periods of market stress.
