The Global ex US Core Fixed Income ETF seeks its investment objective by investing primarily in a universe of foreign debt securities. The Portfolio may invest in obligations issued or guaranteed by foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, money market funds, and obligations of supranational organizations. At the present time, the Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries. However, the Advisor may invest in issuers located in other countries as well, which may include emerging markets. The Advisor selects the Portfolio’s foreign country and currency compositions based on an evaluation of various factors, including, but not limited to, relative interest rates and exchange rates.

The Portfolio may invest in fixed income securities considered investment grade at the time of purchase (e.g., rated AAA to BBB- by S&P Global Ratings ("S&P") or Fitch Ratings Ltd. ("Fitch") or Aaa to Baa3 by Moody's Investor's Service, Inc. ("Moody's")). The Portfolio may invest with an emphasis on fixed income securities rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody's. The Portfolio will be managed with a view to capturing expected credit premiums and expected term premiums. The term "expected credit premium" means the expected incremental return on investment for holding obligations considered to have greater credit risk than direct obligations of the U.S. Treasury, and "expected term premium" means the expected relative return on investment for holding securities having longer-term maturities as compared to shorter-term maturities. In managing the Portfolio, the Advisor will increase or decrease investment exposure to intermediate-term securities depending on the expected term premium and also increase or decrease investment exposure to lower-rated investment grade securities (i.e., those rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody’s) depending on the expected credit premium.

The Portfolio intends to invest its assets to gain exposure to at least three different countries, excluding the United States. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities.

Generally, the Portfolio will purchase fixed income securities that mature within twenty years from the date of settlement. Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater than, and no less than one year below, the weighted average duration of the Bloomberg Global Aggregate ex-USD Bond Index (Hedged to USD), which was approximately 7.16 years as of December 31, 2023. From time to time, the Portfolio may deviate from this duration range when the Advisor determines it to be appropriate under the circumstances. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

Because many of the Portfolio’s investments may be denominated in foreign currencies, the Portfolio may enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio's total return. The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure, including adjustments based on actual or expected cash inflows to or outflows from the Portfolio.

The Portfolio may lend its portfolio securities to generate additional income.

The Portfolio is an actively managed exchange-traded fund and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than such index funds.
