Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM FOR THE PERIOD AND WHAT IMPACTED ITS PERFORMANCE? Management's Discussion of Fund Performance The Alerian MLP ETF delivered a total return of 25.74% for the twelve-month period ended November 30, 2024. This compares to the Alerian MLP Infrastructure Index (the "Underlying Index"), which increased 22.40% on a price-return basis and 31.89% on a total-return basis. The difference in performance between the Fund and its Underlying Index is primarily attributable to the Fund's operating expenses and the tax impact of the Fund's C-Corporation structure, including the accrual of approximately $465.9 million in income tax expense during the period. Pipeline Transportation | Natural Gas was the best-performing subsector and benefitted from an improving multi-year outlook for US natural gas demand driven by liquefied natural gas (LNG) exports and power generation. Gathering & Processing and Pipeline Transportation | Petroleum also performed well. All subsectors saw positive total returns during the period. Liquefaction, which only includes Cheniere Energy Partners (CQP), was the worst-performing subsector as global prices for LNG remained well below 2022 highs and CQP lowered the variable component of its distribution paid in May 2024.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM FOR THE PERIOD AND WHAT IMPACTED ITS PERFORMANCE? Management's Discussion of Fund Performance The Alerian Energy Infrastructure ETF delivered a total return of 50.02% for the twelve-month period ended November 30, 2024. This compares to the Fund's Underlying Index, which increased 42.55% on a price-return basis and 51.22% on a total-return basis. Energy infrastructure companies broadly saw strong performance in the period, including noticeable gains following the election. The best-performing subsector in the portfolio was Pipeline Transportation | Natural Gas, followed by Gathering & Processing. These subsectors have benefitted from a strengthening multi-year outlook for North American natural gas demand. Energy infrastructure companies will play a critical role in transporting natural gas to demand centers, while also helping facilitate the production growth required to meet new demand. All subsectors saw double-digit percentage total returns during the period. ENFR: Index Performance Attribution as of the end of the Period.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM FOR THE PERIOD AND WHAT IMPACTED ITS PERFORMANCE? ●REIT share prices enjoyed a strong recovery for the fiscal year ending November 30, 2024, as the S&P United States REIT Index was up 28.64% for the period, outpacing most other sectors of the market. The Fund was up 27.28% for the fiscal year, net of all fees and expenses, slightly lagging the benchmark. Key drivers of the strong absolute performance were a combination of overly discounted valuations at the beginning of the year, investor rotation out of large cap technology stocks into more value-oriented areas including REITs, and the beginning of monetary easing and a decline in short-term interest rates. ●The Fund benefited from broad-based contribution to total returns from its portfolio holdings, with the largest contributors to the Fund's total returns coming from holdings in the healthcare, storage and industrial property sectors. Key positive contributors to excess returns included stock selection in the lodging and office sectors. Within the broader lodging category, the portfolio was underweight the lagging hotel sub-sector and overweight the outperforming gaming sub-sector. ●The largest detractors of relative returns were the Fund's overweight position in the underperforming single-family rental property sector, stock selection and allocation within healthcare and its property subsectors, and an underweight position in outperforming specialty REITs, specifically those focused on technology and data storage. ●Earnings growth has been one of the primary drivers of investment performance for the REIT universe this year as sectors and individual companies with high actual and expected growth rates have generated strong total returns. The best examples of this trend include companies in the senior housing and specialty REIT sectors. ●The underperforming property sectors for the year have generally been those experiencing a deceleration in earnings growth. The industrial and single-family rental sectors have been two of the weakest performing sectors for the year, as both have seen declining growth in earnings and net operating income from previously high levels. Despite the recent slowdown, these sectors should benefit from favorable, long-term secular fundamentals and do well over the long term. The hotel and cold storage sectors have also suffered from weakening demand and operating results but may be poised for a recovery as both are trading at discounted valuations that could provide the potential for favorable returns should business recover.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM FOR THE PERIOD AND WHAT IMPACTED ITS PERFORMANCE? The ALPS Intermediate Municipal ETF (the "Fund") produced a total return of 5.46% for the twelve-month period ending November 30, 2024. In comparison, its benchmark, the Bloomberg Municipal Bond 1-15 Year Blend Index, had a return of 3.83% over the period. Throughout the measurement period, changing investor expectations regarding inflation and monetary policy drove significant market volatility. For the twelve-month period, 10-year maturity municipal yields increased 15 basis points, the 5-year maturity remained unchanged and short maturity yields declined by 15 basis points. The Fed's tightening cycle officially ended in September when they reduced their policy rate by 50 basis points. Although core measures of inflation remain moderately above the Fed's target of 2%, they have fallen substantially. This gave the Fed confidence to ease rates to help support the labor market. The credit-sensitive portions of the Municipal market performed very strongly. Relative to Triple-A rated securities, Triple-B rated bonds and Municipal High Yield outperformed by 300 basis points and 700 basis points, respectively during the year. A core element of the Fund's strategy is to focus on smaller areas of the market and own securities that are structurally more complex. This has allowed us to enhance the risk-adjusted return of the Fund. To help preserve Fund liquidity, we focus on high quality securities in these areas. Against this backdrop, the Fund outperformed its benchmark by 1.63%. Despite the Fund's low exposure to Triple B rated bonds and no high yield positions, it still performed well relative to its benchmark and its peers. The Fund's significant holdings of State Housing Finance Authorities, Prepaid Natural Gas, and Airports were large contributors to performance. Also enhancing returns were the Fund's positions in zero-coupon bonds and floating rate notes.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM FOR THE PERIOD AND WHAT IMPACTED ITS PERFORMANCE? Top contributors to relative performance: Asset allocation, specifically an overweight allocation to corporate credit—generically including investment grade, high yield, and preferred securities—benefited from tightening risk asset spreads throughout the period. Security selection across investment grade and high yield credit allocations. Agency mortgage security selection, with a relative overweight allocation to high-coupon mortgage-backed securities, which outperformed during the period. Top detractors from relative performance: Yield curve positioning with U.S. Treasuries, with an overweight allocation to the short and long duration areas of the market and a relative underweight to the belly of the yield curve, which outperformed. Underweight asset allocation to Agency mortgages during the period, which outperformed the broader index. Allocations to longer duration Single A rated corporates, which underperformed compared to the broader investment grade corporate universe.
