LIBOR -	London Interbank Offered Rate
SOFR -	Secured Overnight Financing Rate
PRIME -	United States Federal Reserve Overnight Rate
1	Security is fair valued under the Board of Trustees and is categorized as a Level 3 security.  Significant unobservable inputs were used to determine fair value.
2	Variable rate security; rate shown is the rate in effect on December 31, 2022.
3	Bank loans generally pay interest at rates which are periodically determined by reference to a base lending rate plus a premium. All loans carry a variable rate of interest. These base lending rates are generally (i) the Prime Rate offered by one or more major United States banks, (ii) the lending rate offered by one or more European banks such as the London Interbank Offered Rate (“LIBOR”) or (iii) the Certificate of Deposit rate. Bank Loans, while exempt from registration, under the Securities Act of 1933, contain certain restrictions on resale and cannot be sold publicly. Floating rate bank loans often require prepayments from excess cash flow or permit the borrower to repay at its election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy.
4	The Money Market Deposit Account (the “MMDA”) is a short-term investment vehicle in which the Fund holds cash balances. The MMDA will bear interest at a variable rate that is determined based on conditions and may change daily and by any amount. The rate shown is as of December 31, 2022.
5	Security is in default.

Summary of Fair Value Disclosure at December 31, 2022 (Unaudited)

The Osterweis Short Duration Fund (the "Fund"), utilizes various methods to measure the fair value of its investments on a recurring basis.  U.S. GAAP establishes a hierarchy that prioritizes inputs to valuation methods.  The three levels of inputs are:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities that the Fund has the ability to access.

• Level 2 — Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.  These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

• Level 3 — Unobservable inputs for the asset or liability, to the extent relevant observable inputs are not available; representing the Fund’s own assumptions about the assumptions a market participant would use in valuing the asset or liability, and would be based on the best information available.

The following is a summary of the inputs used to value the Fund's investments as of December 31, 2022:
