| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • Tax-Exempt municipal bonds yields followed US Treasury yields in a fairly volatile year for rates as the market attempted to predict future inflation rates, the speed and timing of the Federal Reserve cutting Federal Funds rates, and whether or not the economy would fall into recession or sustain positive growth. • Yields on the Bloomberg AAA municipal 10 year rose 77 basis points (bps) during September-October, fell 138 basis points during November-December, rose 83 basis points January-April, and then rallied 78 basis points May-August to end the volatile fiscal year at lower yields. • California municipal bonds posted strong returns for the fiscal year ending August 31, 2024. Though we saw substantial rate volatility, at fiscal year-end rates were lower across the municipal bond curve driving price appreciation in addition to the coupon income. • The Green CA Tax-free Income Fund returns trailed the benchmark index due primarily to the Fund having a shorter duration than the benchmark during the period which results in less price appreciation when yields fall. |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • It was a volatile year for US Treasury yields based on changing market sentiments predicting the future inflation rate, the speed and timing of the Federal Reserve FOMC cutting Federal Funds rates, and whether or not the economy would fall into recession or sustain positive growth. • The first two month of the fiscal year, rates continued a trend toward higher rates, with the 10 year bond starting the year at 4.11% and reaching the year’s high of 4.99% in mid-October. November and December saw a strong rally with the 10 year bond falling to 3.80% in the last week of December. January to April yields once again moved higher, hitting 4.71% in the last week of May. May through August saw yields trend lower, going as low as 3.79% on August 2 and ending the fiscal year at 3.90% • Anticipating falling interest rates, the fund started the year with slightly longer duration than the Bloomberg US Treasury Index, 6.08 vs 5.95, and moved relatively longer throughout the year to end at 7.23 vs 5.97 for the Index. • The fund was positioned as a ‘barbell’, with more exposure to the long and short end of the curve which provided a higher current yield than the Index and duration exposure for price appreciation if yields dropped. • Though the entire yield curve did drop, the belly of the curve at 5 and 7 years dropped significantly more, 55 and 41 basis points respectively versus 12 and 2 basis points respectively on the 20 and 30 year bonds. • Though the shorter dated bond valuations aren’t as sensitive to interest rate moves as longer dated bonds, the much larger move in the belly of the curve where the fund was underweight led to underperformance of the fund vs the Index. |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • It was a volatile year for US Treasury yields based on changing market sentiments predicting the future inflation rate, the speed and timing of the Federal Reserve FOMC cutting Federal Funds rates, and whether or not the economy would fall into recession or sustain positive growth. • The first two month of the fiscal year, rates continued a trend toward higher rates, with the 10 year bond starting the year at 4.11% and reaching the year’s high of 4.99% in mid-October. November and December saw a strong rally with the 10 year bond falling to 3.80% in the last week of December. January to April yields once again moved higher, hitting 4.71% in the last week of May. May through August saw yields trend lower, going as low as 3.79% on August 2 and ending the fiscal year at 3.90% • Anticipating falling interest rates, the fund started the year with slightly longer duration than the Bloomberg US Treasury Index, 6.08 vs 5.95, and moved relatively longer throughout the year to end at 7.23 vs 5.97 for the Index. • The fund was positioned as a ‘barbell’, with more exposure to the long and short end of the curve which provided a higher current yield than the Index and duration exposure for price appreciation if yields dropped. • Though the entire yield curve did drop, the belly of the curve at 5 and 7 years dropped significantly more, 55 and 41 basis points respectively versus 12 and 2 basis points respectively on the 20 and 30 year bonds. • Though the shorter dated bond valuations aren’t as sensitive to interest rate moves as longer dated bonds, the much larger move in the belly of the curve where the fund was underweight led to underperformance of the fund vs the Index. |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • For the fiscal year ended August 31, 2024, inflation decreased from 3.7% year-over-year (“YoY”) to 2.5% YoY, trending towards the Fed’s long term inflation targets. This set up an environment that was generally favorable to equities as the Fed ended its rate hiking regime and market expectations shifted towards a rate cutting regime. The fund had a correlation of 1.00 against its benchmark, the S&P 500 Index, according to Bloomberg, LLC. • The Information Technology GICS sector contributed the most to the fund’s total return, gaining over 38%. Within this sector, the Semiconductors & Semiconductor Equipment industry drove most of the returns, gaining over 81% for the year. Additionally, the Financials sector was the second largest contributor, returning over 35% for the period, led by the Financial Services industry which returned over 28%. • Contrarily, the GICS Energy sector, for which the only industry exposure was in the Energy industry, returned less than 6% for the year. Additionally, the Materials industry, within the Materials sector, returned less than 16%. There was no GICS sector, which in aggregate, detracted from the fund’s total return. • In terms of specific stock holdings, Nvidia, Microsoft, Apple, and Meta were the top four contributors to the total return of the fund, gaining over 141%, 28%, 22%, and 76% respectively.

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • For the fiscal year ending August 31, 2024 inflation decreased from 3.7% year-over-year (“YoY”) to 2.5% YoY, trending towards the Fed’s long term inflation targets. This set up an environment that was generally favorable to equities as the Fed ended its rate hiking regime and market expectations shifted towards a rate cutting regime. The fund had a correlation of 1.00 against its benchmark, the S&P MidCap 400 Index, according to Bloomberg, LLC. • The Financials GICS sector contributed the most to the fund’s total return, gaining over 30%. Within this sector, the Financial Services industry drove most of the returns, gaining over 29% for the year. Additionally, the Industrials sector was the second largest contributor returning over 18% for the period, led by the Capital Goods industry which returned over 20%. • Contrarily, the GICS Energy sector, for which the only industry exposure was in the Energy industry, detracted from performance with a loss of less than 1% for the year. Additionally, the Communication Services Sector also detracted from performance with a loss of less than 1% for the year, led by the Media & Entertainment industry, which lost over 1%. • In terms of specific stock holdings, Super Micro Computer, Vistra Corp, Deckers Outdoor, and GoDaddy were the top four contributors to the total return of the fund, gaining over 231%, 166%, 71%, and 84% respectively.

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • Performance from Key Holdings: Significant contributions from top performers like NVIDIA (NVDA), AbbVie (ABBV), and Amazon (AMZN) positively impacted the Fund's overall performance, as these stocks demonstrated substantial price appreciation. • Use of Covered Call Strategy: The Fund's strategy of writing covered calls on high-quality equities, such as Apple (AAPL) and Microsoft (MSFT), generated premium cash flow that helped mitigate volatility and enhance overall returns, especially during periods of market fluctuation. • Sector Weighting Adjustments: The Fund's strategic sector allocations—particularly in technology, healthcare, and consumer discretionary—aligned well with market trends, contributing to performance compared to the CBOE S&P 500 BuyWrite Index (BXM). • Market Dynamics and Economic Factors: Macro factors, including rising interest rates and inflation concerns, affected investor sentiment. The Fund's focus on equities with robust fundamentals and free cash flow allowed it to perform well amid economic uncertainty. • Diversification Across Strong Companies: The Fund's diversified holdings, including high-growth companies like Broadcom (AVGO) and Intuit (INTU), reduced risk and contributed positively to performance, contrasting with the underperformance of other positions like PayPal (PYPL) and Disney (DIS). |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • Performance from Key Holdings: Significant contributions from top performers like NVIDIA (NVDA), AbbVie (ABBV), and Amazon (AMZN) positively impacted the Fund's overall performance, as these stocks demonstrated substantial price appreciation. • Use of Covered Call Strategy: The Fund's strategy of writing covered calls on high-quality equities, such as Apple (AAPL) and Microsoft (MSFT), generated premium cash flow that helped mitigate volatility and enhance overall returns, especially during periods of market fluctuation. • Sector Weighting Adjustments: The Fund's strategic sector allocations—particularly in technology, healthcare, and consumer discretionary—aligned well with market trends, contributing to performance compared to the CBOE S&P 500 BuyWrite Index (BXM). • Market Dynamics and Economic Factors: Macro factors, including rising interest rates and inflation concerns, affected investor sentiment. The Fund's focus on equities with robust fundamentals and free cash flow allowed it to perform well amid economic uncertainty. • Diversification Across Strong Companies: The Fund's diversified holdings, including high-growth companies like Broadcom (AVGO) and Intuit (INTU), reduced risk and contributed positively to performance, contrasting with the underperformance of other positions like PayPal (PYPL) and Disney (DIS). |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • For the fiscal year ending August 31, 2024 inflation decreased from 3.7% year-over-year (“YoY”) to 2.5% YoY, trending towards the Fed’s long term inflation targets. This set up an environment that was generally favorable to equities as the Fed ended its rate hiking regime and market expectations shifted towards a rate cutting regime. The fund had a correlation of 1.00 against its benchmark, the Nasdaq-100 Index, according to Bloomberg, LLC. • The Information Technology GICS sector contributed the most to the fund’s total return, gaining over 34%. Within this sector, the Semiconductors & Semiconductor Equipment industry drove most of the returns, gaining over 58% for the year. Additionally, the Communication Services sector was the second largest contributor, returning over 33% for the period, led by the Media & Entertainment industry which returned over 32%. • Contrarily, the GICS Real Estate sector, for which the only industry exposure was in the Real Estate management & Development industry, was the only sector that detracted from the fund’s performance with a loss of more than 5% for the year. Additionally, the Materials industry within the Materials sector contributed the least to the fund’s performance with a gain of less than 3%. • In terms of specific stock holdings, Nvidia, Meta, Broadcom, and Microsoft were the top four contributors to the total return of the fund, gaining over 141%, 76%, 79%, and 28% respectively. Conversely, the top four detractors were Tesla, Intel, Comcast, and Cisco, which lost over 17%, 36%, 12%, and 9% respectively for the fund’s fiscal year. |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • For the fiscal year ending August 31, 2024 inflation decreased from 3.7% year-over-year (“YoY”) to 2.5% YoY, trending towards the Fed’s long term inflation targets. This set up an environment that was generally favorable to equities as the Fed ended its rate hiking regime and market expectations shifted towards a rate cutting regime. The fund had a correlation of 1.00 against its benchmark, the Nasdaq-100 Index, according to Bloomberg, LLC. • The Information Technology GICS sector contributed the most to the fund’s total return, gaining over 34%. Within this sector, the Semiconductors & Semiconductor Equipment industry drove most of the returns, gaining over 58% for the year. Additionally, the Communication Services sector was the second largest contributor, returning over 33% for the period, led by the Media & Entertainment industry which returned over 32%. • Contrarily, the GICS Real Estate sector, for which the only industry exposure was in the Real Estate management & Development industry, was the only sector that detracted from the fund’s performance with a loss of more than 5% for the year. Additionally, the Materials industry within the Materials sector contributed the least to the fund’s performance with a gain of less than 3%. • In terms of specific stock holdings, Nvidia, Meta, Broadcom, and Microsoft were the top four contributors to the total return of the fund, gaining over 141%, 76%, 79%, and 28% respectively. Conversely, the top four detractors were Tesla, Intel, Comcast, and Cisco, which lost over 17%, 36%, 12%, and 9% respectively for the fund’s fiscal year. |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? • For the fiscal year ending August 31, 2024 inflation decreased from 3.7% year-over-year (“YoY”) to 2.5% YoY, trending towards the Fed’s long term inflation targets. This set up an environment that was generally favorable to equities as the Fed ended its rate hiking regime and market expectations shifted towards a rate cutting regime. The fund had a correlation of 1.00 against its benchmark, the Nasdaq-100 Index, according to Bloomberg, LLC. • The Information Technology GICS sector contributed the most to the fund’s total return, gaining over 34%. Within this sector, the Semiconductors & Semiconductor Equipment industry drove most of the returns, gaining over 58% for the year. Additionally, the Communication Services sector was the second largest contributor, returning over 33% for the period, led by the Media & Entertainment industry which returned over 32%. • Contrarily, the GICS Real Estate sector, for which the only industry exposure was in the Real Estate management & Development industry, was the only sector that detracted from the fund’s performance with a loss of more than 5% for the year. Additionally, the Materials industry within the Materials sector contributed the least to the fund’s performance with a gain of less than 3%. • In terms of specific stock holdings, Nvidia, Meta, Broadcom, and Microsoft were the top four contributors to the total return of the fund, gaining over 141%, 76%, 79%, and 28% respectively. Conversely, the top four detractors were Tesla, Intel, Comcast, and Cisco, which lost over 17%, 36%, 12%, and 9% respectively for the fund’s fiscal year. |

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? Mid-cap stock performed well over the time period, delivering an 18.7% return, largely driven by Tech stocks and the euphoria over the promise of Artificial Intelligence. Sustainability stocks were out of favor during this time period, resulting in a low return of 2.75% in NEXTX largely attributed to high interest rates and regulatory uncertainty with the 2024 election. Focusing on industrials and utilities, the hype around data centers and the energy demand required has not yet materialized in corporate earnings and stock prices, resulting in fund under performance relative the MSCI ACWI benchmark.

| Factors Affecting Performance [Text Block] | What affected the Fund's performance this period? Mid-cap stock performed well over the time period, delivering an 18.7% return, largely driven by Tech stocks and the euphoria over the promise of Artificial Intelligence. Sustainability stocks were out of favor during this time period, resulting in a low return of 2.75% in NEXTX largely attributed to high interest rates and regulatory uncertainty with the 2024 election. Focusing on industrials and utilities, the hype around data centers and the energy demand required has not yet materialized in corporate earnings and stock prices, resulting in fund under performance relative the S&P 1500 Index benchmark. Other sectors are also innovating in the field of sustainability, such as consumer products having more recycled content, water and environmental services and climate action. |
