Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks to provide a high level of current income. The Fund is an actively managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in below-investment grade (commonly known as "junk" or “high yield”) fixed income securities, such as bonds and bank loans. It invests in U.S. treasury securities, investment grade bank loans (also known as senior floating rate interests), and preferred securities. The Fund's investments outperformed the Bloomberg U.S. Corporate High Yield 2% Issuer Capped Index ("Index") in the year ending June 30, 2026. The outperformance was driven by positive contribution from issuer selection more than offsetting negative contribution from sector allocation. By issuer, the top contributors included overweight positions in Consolidated Energy Finance SA, Viasat Inc, Park River Holdings Inc, and iHeartCommunications Inc, as well as an underweight position in CSC Holdings LLC. The top detractors included overweight positions in Vibrantz Technologies Inc, LABL Inc, Mercer International Inc, Kronos Acquisition Holdings Inc, and McAfee Corp. Sector allocation provided a modest negative contribution to overall performance as underweight allocations to the insurance and technology sectors were more than offset by underweight allocations to the communications and energy sectors. By quality, the outperformance was driven by positive security selection within BB rated and B rated securities, as well as an underweight allocation to CC rated securities.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks to provide long-term growth of capital. The Fund invests primarily in equity securities of U.S. companies with any market capitalization, but it has a greater exposure to large market capitalization companies than small or medium market capitalization companies. Although there is no restriction on the size of the companies in which the Fund invests, most of the Fund's investments typically include companies with a market capitalization range over $10 billion. Lam Research Corporation (LRCX) contributed to relative performance as the company beat expectations multiple times in the year which was driven by a continued recovery in NAND memory and sustained demand out of China. The company also raised guidance for their wafer fabrication equipment (WFE) outlook to $140 which helped boost the stock. Western Digital Corporation (WDC) benefited from continued margin expansion as customers increasingly adopted high-density drives and new HAMR data storage technologies. GE Vernova Inc. (GEV) aided results as its backlog continued to grow and diversify, reaching 100 gigawatts of contracted gas power capacity across 90 customers in 24 countries. An underweight to Micron Technology, Inc. (MU) detracted from relative performance. Republic Services, Inc. (RSG) is the second largest regulated waste company in North America by market capitalization and revenue. The Fund values RSG’s minimal exposure to recycling and focus on scaling its environmental and hazardous waste assets. RSG detracted from relative results despite growing free cash flow as the company anticipates a 1% revenue decline in 2026 from organic volume decreases. Not owning Intel Corporation (INTC) detracted from relative results as shares rallied over the past year.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of companies with large market capitalizations that, in the opinion of Principal Global Investors, LLC (“PGI”), the Fund’s investment advisor, display characteristics of a “blue chip” company. Over the year, lack of exposure to consumer staples, utilities, and materials contributed to relative performance versus the Russell 1000 Growth Index (“Index"). Amphenol was a top contributor, serving as a critical supplier to the electronics ecosystem by providing cables, sensors, and antennas used in applications ranging from mobile devices to AI data centers. Global hotel company Hilton also contributed to performance, supported by continued execution and the addition of hundreds of properties to its portfolio over the past year. Company selection in information technology and financials detracted from performance. In technology, Microsoft was the largest detractor as the company navigated a period of elevated capital expenditures tied to the rollout of AI Copilot across its platform. A lower allocation to technology hardware businesses also detracted from performance relative to the Index, particularly given continued investor enthusiasm for AI-related infrastructure. Netflix detracted following two unsuccessful acquisition bids and the announcement that its founder is stepping down from the Board. Commercial real estate data and analytics company CoStar also detracted from performance, as it continued to navigate a period of elevated investment in its homes.com business.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities. The Fund invests primarily in foreign equity securities, including emerging market securities. It invests in equity securities of small, medium, and large market capitalization companies. For the year ending June 30, 2026, the Fund's investments underperformed the benchmark, the MSCI ACWI ex USA Index (“Index”). Stock selection contributed positively in South Korea and the Netherlands, as well as within the information technology sector. These gains were more than offset by weaker results in the United Kingdom and Japan and by unfavorable stock selection within the communication services sector. Overweight positions in information technology companies Samsung Electronics and ASML Holding, European financial institutions Erste Group Bank and AIB Group, and Canadian energy producer Suncor Energy were among the most significant contributors to performance during the year. Conversely, performance was negatively impacted by overweight positions in Japanese video game company Nintendo, South Korean semiconductor manufacturer SK Hynix, and UK-based gaming and betting operator Entain plc. Portfolio construction remains primarily driven by bottom-up stock selection, with a focus on identifying company-specific opportunities that we believe can generate attractive long-term risk-adjusted returns.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks to provide current income and, as a secondary objective, capital appreciation. The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in investment-grade corporate bonds and other fixed income securities. "Investment grade" securities are rated BBB- or higher by S&P Global Ratings ("S&P Global") or Baa3 or higher by Moody's Investors Service, Inc. ("Moody's"). During the 12 months ending June 30, 2026, the Fund’s investments outperformed the Bloomberg U.S. Corporate Investment Grade Index (“Index”). Outperformance was driven by favorable security selection, particularly within the banking, technology, capital goods, consumer non-cyclical and energy sectors. This was offset in part by security selection in the transportation and real estate investment trusts (“REITs”) sectors. Moreover, sector allocation slightly detracted from relative performance as an overweight allocation to financials and an underweight to industrials was a drag on performance. Conversely, an overweight allocation to utilities contributed positively to relative performance. Finally, duration and yield curve positioning had a negative impact, with the Fund’s duration position slightly longer than that of the Index, on average. To that end, the Fund utilized derivatives to manage overall duration and key rate exposure relative to the Index.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks long-term growth of capital. Under normal circumstances, the Fund primarily invests in equity securities. For security selection and portfolio construction, Principal Global Investors, LLC (“PGI”) uses a proprietary quantitative model designed to identify equity securities in the S&P 500 Growth Index ("Index") that exhibit growth characteristics, including higher quality, growth potential, and pricing power. The Fund’s investments underperformed the Index over the year. Seven of the eleven sectors in the Index posted positive returns, led by industrials and information technology. Utilities and materials lagged during the year. Sandisk Corp., Micron Technology Inc., and Applied Materials Inc. outperformed within the Index, while Intuit Inc., Fiserv Inc., and Boston Scientific Corp. underperformed. High beta and high momentum stocks outperformed during the year, while high quality stocks underperformed. The Fund’s positioning in Applied Materials Inc., Palo Alto Networks Inc., and NetApp Inc. contributed to performance. Positioning in Intuit Inc., Salesforce Inc., and Boston Scientific Corp. detracted from performance. The Fund’s factor exposure to investment quality contributed to performance, while exposure to low momentum, low beta, and smaller size detracted from performance. Underweight allocations to consumer staples and utilities, along with stock selection within energy, contributed to performance. Selection in information technology, healthcare, and financials detracted.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks total return and income. Under normal circumstances, the Fund invests at least 80% of its net assets in securities of companies principally engaged in the real estate industry. It invests primarily in equity securities, including those of small companies. U.S. real estate securities navigated a volatile macro environment defined by shifting rate expectations, geopolitical shocks, and a powerful artificial intelligence-driven equity rally. U.S. senior housing stocks were the key contributor to performance with these stocks demonstrating continued strong earnings growth and guidance upgrades supported by firming occupancy, improving pricing power, and accretive acquisitions. Data center selection also contributed, particularly, a network dense colocation operator which outperformed strongly. Performance was partially offset by the position in towers which lagged on concerns of weak earnings outlook and slowing carrier capital expenditure.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks to provide current income. Under normal circumstances, the Fund invests at least 80% of its net assets in preferred securities and other income-producing securities. The preferred securities in which the Fund invests include, but are not limited to, preferred stock, certain depositary receipts, and various types of junior subordinated debt. The Fund invests significantly in securities that, at the time of issuance, are eligible to pay dividends that qualify for favorable U.S. federal income tax treatment, such as dividends treated as “qualified dividend income” (“QDI”). The Fund also invests in derivative instruments for hedging and income generation purposes. During the 12 months ending June 30, 2026, the 5-year U.S. Treasury note yield rose 49 basis points (“bps”) to a yield-to-worst (“YTW”) of 4.28%. Bond investor anxieties rose from fears of another trade war, uncertainty increased over the ongoing annual fiscal deficit, and a war with Iran spiked oil prices and reignited inflation fears. Despite rising U.S. Treasury yields, both the average price of the Fund’s investments and the YTW of the Fund’s investments increased. Credit spreads within the portfolio tightened to an option adjusted spread of +191 bps. Within the Fund’s benchmark, the ICE BofA 7% Constrained DRD Eligible Preferred Securities Index (“Index”), security average price declined, YTW rose, and credit spreads tightened to an option adjusted spread of +118 bps. The Fund was overweight in contingent convertible capital securities (“CoCos”) and overweight in limited recourse capital notes of Canadian banks which contributed to the excess return of the Fund compared to the Index. The Fund was underweight in $1000 par U.S. bank preferred securities and underweight in $25 par preferred stock which detracted from the performance of the Fund compared to the Index. The Fund’s income outpaced the Index for the year. Overall, the rising rate market conditions detracted from the Fund’s performance compared to the Index and tighter spreads contributed to the Fund’s performance compared to the Index.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks to provide current income. Under normal circumstances, the Fund invests at least 80% of its net assets in preferred securities. Examples of preferred securities include preferred stock, certain depositary receipts, and various types of junior subordinated debt (such debt generally includes the contractual ability to defer payment of interest without accelerating an immediate default event). It concentrates its investments (invests more than 25% of its net assets) in securities in one or more industries within the financial services sector. During the 12 months ending June 30, 2026, the 5-year U.S. Treasury note yield rose 49 basis points (“bps”) to a yield-to-worst (“YTW”) of 4.28%. Bond investor anxieties rose from fears of another trade war, uncertainty increased over the ongoing annual fiscal deficit, and a war with Iran spiked oil prices and reignited inflation fears. Despite rising U.S. Treasury yields, both the average price of the Fund’s investments and the YTW of the Fund’s investments increased. Credit spreads within the portfolio tightened to an option adjusted spread of +169 bps. The Fund’s benchmark, the ICE BofA U.S. Investment Grade Institutional Capital Securities Index (“Index”), also experienced an increase in security average price and YTW, along with tightening credit spreads, although to a lesser extent than the Fund. The Fund was overweight in $1000 par U.S. bank preferred securities and overweight in limited recourse capital notes of Canadian banks which contributed to the excess return of the Fund compared to the Index. The Fund was underweight in corporate hybrids and underweight in insurance hybrids which detracted from the Fund’s performance compared to the Index. The Fund’s income lagged the Index for the year, but this was more than offset by the Fund’s lower duration and better spread performance. Overall, the rising rate market conditions detracted from the Fund’s performance compared to the Index and tighter spreads contributed to the Fund’s performance compared to the Index.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of U.S. companies with very large ("mega") market capitalizations. For this Fund, companies with mega capitalizations are those with market capitalizations in the top 50th percentile of the S&P 500 Index ("Index") at time of purchase. The Fund’s investments underperformed the Index over the year. All eleven sectors in the Index posted positive returns, led by information technology and energy. Financials and consumer staples lagged during the year. Sandisk Corp., Western Digital Corp., and Micron Technology Inc. outperformed within the Index, while Trade Desk Inc., Fiserv Inc., and Gartner Inc. underperformed. High beta and high momentum stocks outperformed during the year, while high quality stocks underperformed. The Fund’s positioning in Micron Technology Inc., Johnson & Johnson, and Exxon Mobil Corp. contributed to performance. Positioning in Netflix Inc., Mastercard Inc., and Costco Wholesale Corp. detracted from performance. The Fund’s factor exposure to size and high momentum contributed to performance, while exposure to high quality and low beta detracted from performance.

The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of U.S. companies with small market capitalizations. For this Fund, companies with small market capitalizations are those with market capitalizations within the range of companies comprising the Russell 2000 Index ("Index"). The Fund’s investments underperformed the Index over the year. All eleven sectors within the Index posted positive returns, led by information technology and healthcare, while consumer staples and utilities lagged. Erasca Inc., Terns Pharmaceuticals Inc., and Bloom Energy Corp. outperformed within the Index, while Trinseo PLC, zSpace Inc., and Sleep Number Corp. underperformed. High beta and high momentum stocks outperformed during the year, while high quality stocks underperformed. The Fund’s positioning in TTM Technologies Inc., Argan Inc., and DigitalOcean Holdings Inc. contributed to performance. Positioning in Dave Inc., Root Inc., and American Eagle Outfitters Inc. detracted from performance. The Fund’s factor exposure to high momentum and earnings yield contributed to performance. Exposure towards high quality and low beta, along with exposure away from book yield, detracted from performance. Stock selection within industrials, energy, and real estate contributed to performance, while selection in healthcare, information technology, and financials detracted.

Factors Affecting Performance [Text Block]

Management's Discussion of Fund Performance

The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of value companies. For this Fund, value companies are those (i) with market capitalizations within the range of companies comprising the S&P 500 Index and (ii) included within the S&P 500 Value Index ("Index"). Principal Global Investors, LLC ("PGI") uses a proprietary quantitative model designed to identify equity securities of mid- to large-capitalization companies in the S&P 500 Index that exhibit higher degrees of shareholder yield (meaning how much money a company distributes to shareholders through dividends and share repurchases). The Fund’s investments underperformed the Index over the year. Ten of the eleven sectors in the Index posted positive returns, led by information technology and energy. Communication services and consumer discretionary lagged during the year. Western Digital Corp., Seagate Technology Holdings PLC, and Intel Corp. outperformed within the Index, while Charter Communications Inc., CoStar Group Inc., and Intuit Inc. underperformed. High beta and high momentum stocks outperformed during the year, while high quality stocks underperformed. The Fund’s positioning in Caterpillar Inc., Dell Technologies Inc., and Invesco Ltd. contributed to performance. Positioning in Intuit Corp., Accenture PLC, and Salesforce Inc. detracted from performance. The Fund’s factor exposure to value oriented factors contributed to performance, while exposure to smaller size, lower momentum, and higher quality detracted from performance. Stock selection within consumer discretionary, financials, and healthcare contributed to performance. Selection in information technology, consumer staples, and industrials detracted from performance.
