Shareholder Letter

January 14, 2020

Dear Shareholders,

During the fourth quarter of 2019, the Osterweis Strategic Income Fund (the Fund) generated a total return of 0.50%, compared to 0.18% for the Bloomberg Barclays U.S. Aggregate Bond Index (BC Agg). The Fund’s annualized total returns over the one-year, five-year and ten-year periods ending December 31, 2019 were 5.35%, 4.04% and 5.05%, respectively, compared to 8.72%, 3.05% and 3.75% for the BC Agg over the same periods.

The performance data quoted above represent past performance. Past performance does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance of the Fund may be lower or higher than the performance quoted. Performance data current to the most recent month end may be obtained by calling (866) 236-0050. An investment should not be made solely on the basis of returns. The Fund’s gross expense ratio was 0.85% as of March 31, 2019.

The fourth quarter capped off a strong year for both equities and fixed income. Accommodative Federal Reserve policy combined with benign economic conditions pushed asset prices higher across the board in 2019. Although most sectors delivered favorable returns, there were material differences in investor preferences in high yield versus investment grade. Within high yield there was a significant flight to quality, as the ICE BofA BB Index outperformed all other sectors of the high yield market. On the other hand, within investment grade there was a stretch for yield, as the ICE BofA BBB Index performed best.

Following the sustained rally in high yield, the market is now priced nearly to perfection, which is a bit too optimistic in our view. We expect to see more differentiation between issuers in 2020 as well as a reversion to more normal spreads between lower and higher quality cohorts. As such, we believe lower rated and some non-benchmark bonds will likely perform better.

Given the low absolute yield levels, we are selectively investing in credits that we expect to rebound in 2020 if economic prospects continue to improve. We are still focusing on the front end of the curve, as global central banks are beginning to reconsider their negative interest rate policies. Interest rate risk in investment grade and longer duration bonds remains near historic highs and we would rather not increase our exposure at this time.

Thank you for your continued support.

Mutual fund investing involves risk. Principal loss is possible.

The Osterweis Strategic Income Fund may invest in debt securities that are un-rated or rated below investment grade. Lower-rated securities may present an increased possibility of default, price volatility or illiquidity compared to higher-rated securities. The Fund may invest in foreign and emerging market securities, which involve greater volatility and political, economic and currency risks and differences in accounting methods. These risks may increase for emerging markets. Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities. Small- and mid-capitalization companies tend to have limited liquidity and greater price volatility than large-capitalization companies. Higher turnover rates may result in increased transaction costs, which could impact performance. From time to time, the Fund may have concentrated positions in one or more sectors subjecting the Fund to sector emphasis risk. The Fund may invest in municipal securities which are subject to the risk of default.

While the fund is no-load, management fees and other expenses still apply. Please refer to the prospectus for more information.
