1 A basis point is equal to 1/100th of 1% and is used to express small changes in interest rates, yields, and financial indices.
2 The federal funds rate is the target interest rate set by the Federal Open Market Committee. This target is the rate at which commercial banks borrow and lend their excess reserves to each other overnight.
3 Quantitative tightening is a monetary policy strategy where a central bank reduces the size of its balance sheet—typically by selling government bonds or letting them mature—thereby decreasing liquidity in the financial system.
4 Duration is a measure of the sensitivity of an investment’s price to nominal interest-rate movement.
5 The Secured Overnight Financing Rate (SOFR) reflects the cost of overnight borrowing using U.S. Treasury bonds as collateral. It's a risk-free rate based on actual market transactions.
6 The Consumer Price Index is a measure of change in consumer prices as determined by the US Bureau of Labor Statistics.
7 Owners’ equivalent rent is the amount of rent that would have to be paid in order to substitute a currently owned house as a rental property.
8 Treasury Inflation-Protected Securities are Treasury bonds that are adjusted to eliminate the effects of inflation on interest and principal payments, as measured by the CPI.
9 The BIS 50% Rule restricts US exports to any company that is 50% or more owned by a sanctioned entity, even if that company itself isn’t explicitly listed.
10 The Exchange Stabilization Fund is a US Treasury reserve account used to manage currency stability and respond to financial crises, giving the Treasury flexibility to intervene in foreign exchange markets and support global financial stability without needing Congressional approval.
11 A swap line is an agreement between two central banks to exchange currencies, allowing one to access foreign currency liquidity, typically US dollars, to stabilize markets and support domestic financial institutions during times of stress.
12 Business development companies are publicly traded investment firms that provide financing to small and mid-sized private companies, often through direct lending, and offer retail investors access to private credit markets with higher yield potential and higher risk.
13 Interval funds are a type of closed-end fund that allows investors to buy shares anytime but only permit redemptions at set intervals, such as quarterly, rather than daily.
14 Total return is the actual rate of return of an investment over a given evaluation period, including interest, capital gains, dividends, and distributions realized during that time.
15 Go-anywhere strategies are benchmark-agnostic and can invest across sectors, credit qualities, currencies, and countries without preset limits, unlike core-bond-plus strategies, which allow flexibility but impose caps on below-IG, non-US, or sector-specific exposures.
16 Core/core plus strategies typically invest in a baseline of IG bonds such as government, corporate, and securitized debt. Core-plus funds can take that baseline and add additional sectors such as corporate high-yield, emerging-market debt, or non-US currency exposures to enhance returns.

18 Spreads are the difference in yields between two fixed-income securities with the same maturity but originating from different investment sectors.
19 Leveraged loans are loans made to companies with below-IG credit ratings, typically carrying higher interest rates and secured by collateral to compensate for their greater default risk.
20 Subordinated structures are debt or securities that rank below senior obligations in repayment priority, meaning they carry higher risk because they are paid only after senior claims in the event of default.
Important Risks: Investing involves risk, including the possible loss of principal. • Fixed income security risks include credit, liquidity, call, duration, and interest-rate risk. As interest rates rise, bond prices generally fall. • Investments in high-yield (“junk”) bonds involve greater risk of price volatility, illiquidity, and default than higher-rated debt securities. • Mortgage-related and asset-backed securities’ risks include credit, interest-rate, prepayment, and extension risk. The value of the underlying real estate of real estate related securities may go down due to various factors, including but not limited to strength of the economy, amount of new construction, laws and regulations, costs of real estate, availability of mortgages, and changes in interest rates. • Loans can be difficult to value and less liquid than other types of debt instruments; they are also subject to nonpayment, collateral, bankruptcy, default, extension, prepayment and insolvency risks. • Foreign investments may be more volatile and less liquid than US investments and are subject to the risk of currency fluctuations and adverse political, economic and regulatory developments. These risks may be greater, and include additional risks, for investments in emerging markets. • The risks associated with mortgage-related and asset-backed securities as well as collateralized loan obligations (CLOs) include credit, interest-rate, prepayment, liquidity, default, and extension risk.
