TTP and TPZ distribution policies

Tortoise Pipeline & Energy Fund, Inc. (“TTP”) and Tortoise Power and Energy Infrastructure Fund, Inc. (“TPZ”) are relying on exemptive relief permitting them to make long-term capital gain distributions throughout the year. Each of TTP and TPZ, with approval of its Board of Directors (the “Board”), has adopted a managed distribution policy (the “Policy”). Annual distribution amounts are expected to fall in the range of 7% to 10% of the average week-ending net asset value (“NAV”) per share for the prior fiscal semi-annual period. In accordance with its Policy, TTP distributes a fixed amount per common share, currently $0.59, each quarter to its common shareholders. TPZ distributes a fixed amount per common share, currently $0.105, each month to its common shareholders. These amounts are subject to change from time to time at the discretion of the Board. Although the level of distributions is independent of TTP’s and TPZ’s performance, TTP and TPZ expect such distributions to correlate with its performance over time. Each quarterly and monthly distribution to shareholders is expected to be at the fixed amount established by the Board, except for extraordinary distributions in light of TTP’s and TPZ’s performance for the entire calendar year and to enable TTP and TPZ to comply with the distribution requirements imposed by the Internal Revenue Code. The Board may amend, suspend or terminate the Policy without prior notice to shareholders if it deems such action to be in the best interests of TTP, TPZ and their respective shareholders. For example, the Board might take such action if the Policy had the effect of shrinking TTP’s or TPZ’s assets to a level that was determined to be detrimental to TTP or TPZ shareholders. The suspension or termination of the Policy could have the effect of creating a trading discount (if TTP’s or TPZ’s stock is trading at or above net asset value), widening an existing trading discount, or decreasing an existing premium. You should not draw any conclusions about TTP’s or TPZ’s investment performance from the amount of the distribution or from the terms of TTP’s or TPZ’s distribution policy. Each of TTP and TPZ estimates that it has distributed more than its income and net realized capital gains; therefore, a portion of your distribution may be a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in TTP or TPZ is paid back to you. A return of capital distribution does not necessarily reflect TTP’s or TPZ’s investment performance and should not be confused with “yield” or “income.” The amounts and sources of distributions reported are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon TTP’s and TPZ’s investment experience during their fiscal year and may be subject to changes based on tax regulations. TTP and TPZ will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

2024 Semi-Annual Report to closed-end fund stockholders

Dear stockholder,

The fiscal semi-annual period that included the start of 2024 for the energy sector was a good one. Overall performance was positive, and it offered a constructive supply and demand environment, capital allocation discipline, and negligible policy implications. While geopolitical turmoil continued in both Ukraine and Israel, the energy sector sustained flows from areas of supply to demand centers. The Organization of the Petroleum Exporting Countries Plus (OPEC+) remained constant in their goal to balance crude oil markets. And providing a boost to visibility on longer-term crude oil and natural gas demand, electric vehicle sales slowed, and artificial intelligence’s (AI) energy demand needs became clearer. The sector’s essentialness to global economic growth stayed ever apparent.

Energy and power infrastructure

The broad energy sector, as represented by the S&P Energy Select Sector Index®, returned 12.2% for the first half of the 2024 fiscal year. Energy company management teams by and large remain committed to returning cash flow to shareholders in the form of higher dividends and share buybacks, while maintaining strong balance sheets. Along those same lines, mergers and acquisitions (M&A), while elevated, remained disciplined in terms of price paid and the complementary nature of assets acquired. Further aiding the sector were constructive crude oil prices, gross domestic product (GDP) growth leading to more energy demand, softness in electric vehicle sales, and AI related data centers hunger for more energy. Less helpful for the sector were low natural gas prices due to warm winter weather and concerns about a slowing economy.

OPEC+ continued to balance global crude oil supply with demand by extending two million barrels per day (bpd) of production curtailments through September of 2024, before gradually phasing them out. This discipline led to modest oil inventory draws and a constructive crude oil price near $80 and $85 per barrel for West Texas Intermediate (WTI) and Brent at the end of May, respectively. That said, tensions in the Middle East stemming from the Israeli and Hamas conflict along with the war between Russia and Ukraine kept concerns about a supply shock top of mind. Oil transport was disrupted, yet oil continued to find a home even if routes were not the most efficient. Oil demand continued to grow due to a resilient global economy. Average 2024 demand growth over 2023 using forecasts from the International Energy Agency (IEA), Energy Information Administration (EIA) and OPEC is 1.5 million barrels per day (bpd), with 2025 levels also higher by over 1 million bpd. Over the longer-term, less optimism over electric vehicle (EV) penetration following slower sales in the U.S., Europe, and China is leading to a view that gasoline and diesel demand will not peak before 2030. Petrochemical and jet products that make up over 50% of crude oil demand have even firmer growth prospects over the next 20 years.

U.S. crude oil production growth carries on. According to the EIA, U.S. crude oil production rebounded in the second quarter to 13.2 million bpd from the first quarter when harsh winter weather reduced levels to 12.9 million bpd. For the year, the EIA forecasts crude oil production to be 2% better than 2023 levels, and to grow 4% in 2025, averaging 13.7 million bpd. The increased production is largely from the Permian basin, the source of nearly 50% of all domestic crude oil production. This growth is anticipated despite the lower rig count and fewer frac crews as producers are doing more with less.

Drilling laterals lengthened and completion times shortened again. The application of AI is even resulting in improved efficiencies. And aside from labor, oilfield service and material cost inflation are in the past.

U.S. natural gas production declined from 105.6 billion cubic feet per day (bcf/d) in the fourth quarter of 2023 to 100.4 bcf/d in the second quarter of 2024. The reason? Relatively mild winter weather reduced the need for natural gas to heat homes and offices, leaving supply well ahead of demand. Inventories ended the winter withdrawal season above the five-year high. Consequently, producers reduced production to better balance supply and demand. That action is part of the reason natural gas prices improved in May to average $2.40 per million British thermal units (mmbtu) from the March low of $1.58 per mmbtu. The EIA forecasts that second quarter production will be the trough for 2024, with volumes improving every quarter through year-end 2025. Weather will remain a factor, yet new U.S. liquified natural gas (LNG) export facilities are set to start coming on-line later this year that we expect to result in more supply to meet higher natural gas demand. In fact, more LNG export facilities will continue to come on-line in the U.S. through 2027, resulting in an almost doubling of U.S. LNG export capacity. We expect production to keep up with these adds. This increased LNG export will meet both new Asian demand tied to economic growth and European demand as the continent looks for more secure supplies in the face of Russia’s continuing war with Ukraine.

Natural gas liquids (NGLs) are a source of heat and the key components in making plastics. The U.S. is the world’s largest producer of NGLs with production just under 7 million bpd, and the largest exporter at 2.7 million bpd. A unique aspect of Permian basin oil production is that the percent of production that is NGLs increases over time as a well depletes over time. Consequently, NGL supply is sure to grow if crude oil production increases. We expect this increased production to nearly all be exported in part to meet Asia’s growing petrochemical demand.

The midstream energy sector, as represented by the Alerian Midstream Energy Index (AMNA), returned 12.2% for the semi-annual fiscal period, right on top of broader energy’s gain. Supporting the sector were good earnings reports relative to consensus, continued management discipline toward capital allocation and M&A, and benign policy implications from Washington. We think midstream’s growing free cash flow, low leverage, and attractive valuation provide a compelling investment backdrop.

Earnings for midstream companies over the past six months came in at the high end of expectations following strong volumes, the robust 13% inflation tariff escalator, and isolated marketing opportunities from wide price differentials, particularly between west Texas and the Gulf Coast. On capital allocation, healthy balance sheets were maintained with dividend growth and share buybacks remaining a management focus. Leverage targets are now generally between 3.0x to 4.0x earnings before interest, taxes, depreciation and amortization (EBITDA) with leverage being a full “turn” lower versus levels prior to 2020. Buybacks eclipsed $2.3 billion over the past six months and are on pace to exceed our annual buyback expectation of $4 billion. Most notable to capital returns was Cheniere Energy’s outsized share repurchase at over $1.5 billion during the past six months and Western Midstream’s 52% distribution boost. We expect free cash flow to increasingly be targeted at dividend growth and opportunistic share repurchases.

2024 Semi-Annual Report | May 31, 2024

Midstream companies remained active in M&A with two notable corporate transactions. First, Sunoco LP (SUN) agreed to acquire NuStar Energy (NS), a liquids pipeline company, in an all-stock transaction at a 24% premium. Then, EQT Corp (EQT), a large natural gas producer, entered an agreement to acquire Equitrans Midstream (ETRN), a natural gas pipeline and gathering company, in an all-stock transaction at an 18% premium. The commonality between the transactions was the all-equity nature and vertical integration as a rationale. We do not believe vertical integration will emerge as a trend, yet it bears watching. Midstream companies also looked to further boost their asset bases through bolt-on acquisitions from motivated private equity sellers, with three separate deals for Permian basin gathering and processing assets topping $4.5 billion in transaction value. Specifically, Energy Transfer agreed to acquire WTG Midstream, Kinetik bought Durango Midstream, and PSX tapped Pinnacle Midstream. Along with being accretive, the rationale for the Permian focus and synergy is the ability for the acquirors to more fully utilize existing infrastructure to transport increased volumes of natural gas and natural gas liquids to the demand and export center along the Gulf Coast. It was not all buying though. Companies also divested non-core assets, with Kinetik selling its interest in Gulf Coast Express and PSX dealing its position in Rockies Express. We believe complementary asset acquisitions combined with the pruning of non-core assets will continue through the remainder of the year and continue to serve investors well. Speaking of non-core assets, look for TC Energy to complete the announced spin-off of its liquids business, South Bow Corporation (SOBO), in the second half of this year.

The outsized buildout of datacenters to support AI is resulting in meaningful electricity growth in the U.S. after years of relatively stable demand. Further, data centers require a continuous and reliable power supply to ensure uninterrupted operations. We believe that renewables will play a role, yet neither solar nor wind are completely reliable. For that reason, we think natural gas is the best reliable supply source to meet this need because natural gas is relatively low cost, abundant domestically, and cleaner than coal. This idea continued to gain traction during the quarter with AI being mentioned countless times on energy conference calls. We estimate AI power demand growth could require an additional 7 to 16 bcf/d of U.S. natural gas production to meet electricity demand from data centers. We expect this to benefit all forms of natural gas infrastructure over the next five years. And over the more immediate time period, we believe Independent Power Producers (IPPs) will profit from their ability to enter into power supply contracts with data centers and to supply marginal power to data centers when regulated electric utility companies are unable to meet demand. During these time periods, IPPs benefit from outsized power prices.

While U.S. GDP growth improved 3.4% in the fourth quarter of 2023, with further gains to start 2024, some economic signals suggest that a recession is on the horizon. This may weigh on investor psyche until resolved. Regarding energy, while multiple recessions occurred i n the last 40 years, energy demand still increased in 38 out of the last 41 years (2008 and 2020 decreased). Following the 2020 recession, energy companies reduced capital expenditures and focused on reducing debt levels. We believe the energy sector, and specifically midstream, is prepared to deal with a potential recession. With the world remaining undersupplied energy over the longer-term, sector balance sheets now less levered, and management teams looking for share repurchase opportunities, we believe energy is well positioned should slower economic growth manifest.

High inflation persisted in early 2024, though moderated as mid-year approached. Whatever the level, midstream provided investors with inflation protection. Pipelines typically benefit from long-term contracts where tariffs increase based on inflation levels. Further, tariffs on regulated liquids pipelines include an inflation escalator based on the Producer Price Index. Federal Energy Regulatory Commission (FERC) indexing allowed for a tariff increase of over 13% beginning July 1, 2023, until June 30, 2024. We estimate the cumulative total allowable tariff increase since 2020 through year-end 2024 will exceed 26%.

On the policy front, the Department of Energy (DOE) announced a pause in its review of pending LNG export applications. The DOE wants to update its economic and environmental analysis that underpin this review, specifically how it assesses climate change. Importantly, the pause does not affect the projects that have already made a Final Investment Decision. The build-out of new LNG facilities through 2027 is unaffected. We expect that once the Presidential election is over in November, the DOE will lift its pause and continue its review of pending LNG export applications. Lastly, the Mountain Valley Pipeline (MVP) received all construction and operational permits and full authorization under the Fiscal Responsibility Act (FRA) last year. As a reminder, MVP is a 2 bcf/d pipeline transporting natural gas from the Marcellus shale into Virginia. After several years of delay, MVP entered operational service in June of 2024.

Sustainable infrastructure

The semi-annual period ending May 31, 2024, had financial markets experiencing notable shifts and uncertainties, shaped by fluctuating long-term interest rates and geopolitical tensions. Initially, from December to January, there was a pervasive sense of skepticism surrounding the growth potential of pure renewables and utilities due to devalued stock prices that seemingly discounted growth prospects too harshly. However, amidst these challenges, there remained optimism driven by compelling investment opportunities, particularly in sectors benefiting from decarbonization and electrification trends. These included renewables and utilities, which saw elevated power purchase agreement prices reflecting strong demand for cleaner energy sources in Europe and the U.S. As the period progressed, despite initial optimism, broader infrastructure sectors, including utilities, faced significant challenges, with Europe particularly impacted by weak economic conditions and oversupply concerns in energy markets. Conversely, the U.S. market showed resilience driven by robust demand from AI, data centers, and electric vehicles, bolstering the performance of U.S. utilities within portfolios. By March, sentiment began to improve as expectations of lower inflation and potential policy rate cuts emerged, although ongoing uncertainties around interest rates and energy prices continued to weigh on infrastructure valuations.

Through April and May, U.S. utilities emerged as standout performers fueled by increasing power demand, particularly from AI and data centers, highlighting the sector’s pivotal role in supporting technological advancements. Meanwhile, in Europe, despite lagging behind their U.S. counterparts, utilities and environmental services groups still delivered strong performances, buoyed by rising power prices and solid earnings reports. This period also witnessed significant corporate actions such as National Grid’s equity issuance to fund ambitious capex plans, indicative of continued investment in grid infrastructure to support electrification and renewables growth.

Looking ahead, amidst the persisting uncertainties in interest rates and energy prices, buying opportunities remain compelling, especially in sectors poised to benefit from ongoing electrification efforts and technological advancements. The portfolio strategy emphasizes utilities for their predictable earnings growth and the burgeoning demand from data centers and AI applications, which prioritize reliable and clean energy sources. Furthermore, ongoing M&A activity within the sector, fueled by substantial private equity investment, suggests potential for a re-rating of growth opportunities in listed infrastructure, underscoring the sector’s dynamic landscape and future prospects.

Waste transition

The second quarter of 2024 featured announcements detailing a resurgence in green and sustainable project finance activities, indicating continued support for energy and waste transition efforts, despite the unfavorable impacts of a high interest rate environment and a relatively soft macroeconomic environment.

Per Moody’s Investors Service, the global issuance of green, social, sustainability, and sustainability-linked bonds rose 36% in first quarter 2024 over the prior period in fourth quarter 2023. In particular, the global issuance of sustainability bonds nearly doubled over the prior quarter and increased 16% year-over-year. And, per the non-profit Climate Bonds Initiative, the global issuance of green bonds rose 43% in Q1 2024 over the prior period in Q4 2023 and is predicted to total $1 trillion for the full year in 2024. U.S. issuers typically account for the largest geographical share and represented slightly more than 14% of Q1 2024 global green bond issuance. While sustainability bonds and green bonds are typically issued on a public, rated basis, a similar trend in increased issuance has been anecdotally witnessed in the private, non-rated market as well.

In the waste-to-energy sector, there has been significant growth in recent years in the number of projects that convert waste feedstocks into renewable natural gas, or RNG. These RNG projects have been supported by a variety of incentives, including fuel credits provided by the federal Renewable Fuel Standard (RFS) and the California Low Carbon Fuel Standard (LCFS), and by investment tax credits via the Inflation Reduction Act. Because there is substantial growth potential for RNG, which provides a meaningful decarbonization of transportation fuels, there continue to be efforts to encourage more RNG production in the U.S. In May of 2024, the U.S. Senate introduced the Renewable Natural Gas Incentive Act, which if enacted into law would provide a $1 per gallon tax credit for RNG produced and sold as a transportation fuel. Such a per-gallon incentive would put RNG on a more level playing field with Renewable Diesel and Sustainable Aviation Fuel, which each already receive a similar per-gallon production incentive.

In the waste-to-value sector, there has been increased focus on eliminating PFAS, also known as “forever chemicals” and contained in plastic waste, as well as Extended Producer Responsibility laws, which have been primarily directed toward reducing plastic waste.

In April 2024, the U.S. Environmental Protection Agency (EPA) designated two types of PFAS chemicals as Hazardous Materials. The intent of such classification is to hold polluters accountable for the financial burden of removing or destroying PFAS. Initially, the EPA does not intend to pursue municipal landfills or municipal water utilities in its enforcement activities. However, the Hazardous Material classification is expected to result in an industry-wide effort to eliminate PFAS. While early in the cycle, these efforts are expected to bolster the construction of new facilities implementing high-temperature technologies such as gasification, pyrolysis, and incineration — each of which may also be utilized for waste-to-energy or waste-to-value purposes, in addition to PFAS destruction.

In May 2024, the state of Minnesota enacted an Extended Producer Responsibility (EPR) law for plastics packaging waste and boat-wrap waste. Under the law, brand manufacturers are required to pay for plastic recycling costs at an increasing rate over time - 50% of recycling costs beginning in 2029, 75% in 2030, and 90% in 2031. Minnesota is the fifth state to enact an EPR law for plastics packaging, joining California, Colorado, Maine, and Oregon. Although a primary goal of such EPR programs is to reduce the upfront amount of plastic waste generated, their implementation is also expected to result in the construction of new plastics recycling facilities near major metropolitan areas.

Social impact

Education

The public market for issuance of new K-12 charter school and private school revenue bonds year-to-date for 2024 saw similar numbers of bond issuances as the same period in 2023, but with a much higher par value. Through May, there were 35 new issues for $1,603,130,000 as compared to 36 issues for $835,188,000 for the period in 2023. The 2024 numbers include six specialty investor transactions for $129,965,000 versus nine transactions totaling $214,613,000 during the same period in 2023.1

The primary driver of this increase in par value was a greater number of large school portfolio transactions. If the market follows historical trends, Q3 and Q4 should see a significant increase in transactions volume and total par value issuance. While there were only 101 new issues representing $3.459 billion in par value in all of 2023, we believe that to be an outlier as par value for K-12 charter school and private school bonds increased every year from 2011 to 2021 and in 21 of 27 years since 1998.1 With steady municipal bond fund inflows year-to-date ($6.7 billion inflows for 2024 vs $1.4 billion outflows for the period in 2023)2 and the benchmark 30-year MMD daily rate far below 2023’s high of 4.57%, and Q4 2023’s average of 4.06%,3 Ecofin expects to see total par value of over $4.0 billion for K-12 charter school and private school revenue bond issuance in 2024.

During the period, the Equitable Facilities Fund published their report, “2022 Charter School Bond Default Study: Default and Loss Rates Continue to Decline”, which provided valuable bond default analysis based on data from every charter school bond issue ever completed as of December 31, 2022. Some key findings include:

Only “94 charter schools (or their affiliates), representing 99 transactions, or 4.3% of the entire portfolio of 2,298 transactions, have experienced a monetary default in which borrowers failed to make full and timely debt service payments promised at the time of issuance.”
“Primary causes for an obligor’s inability to make scheduled debt service payments were identified as: subpar academic results; financial stress; lower than expected enrollment; governance.”
A median recovery rate of 69.1% when “you combine the 59 foreclosure property sales with the refundings, bond exchanges, and those obligors which were able to overcome the default and make all debt service payments current again.”4

2024 Semi-Annual Report | May 31, 2024

In April, we saw the release of U.S. News & World Report (U.S. News) 2023-2024 rankings of the best public high schools in the country. Nineteen charter schools were recognized in the nation’s top 100 high schools, including the top two spots overall, Arizona’s BASIS Peoria (#1) and Indiana’s Signature School in Evansville (#2). This is particularly impressive when you consider that charter schools make up only about 8% of the nation’s public high schools.5

In addition to charter schools, other school choice options have exploded across the nation. By the end of 2023 seven states enacted new private school choice programs and 11 states expanded existing programs. This has resulted in access to private school choice programs for around 20 million students nationwide.6

Ten states now have universal or near-universal private school choice programs, meaning nearly 100% of their students are eligible to participate in their state’s program. These programs come in the form of education savings accounts, voucher programs or tax credits. Prior to 2023, only Arizona and West Virginia had universal eligibility, but they’ve now been joined by Arkansas, Florida, Indiana, Iowa, North Carolina, Ohio, Oklahoma, and Utah. With 30 states now providing some type of private school choice for families, it is clear that parents will continue to embrace these popular programs and continue to drive their expansion throughout the nation.6

Across the education universe, we continue to see an increase in both volume and credit quality of education investment opportunities through May 2024.

Senior Living

Senior living occupancy continues to improve since the lows of COVID and our senior population is one quarter closer to outpacing the current bed supply. In fact, within one year, the first baby boomer turns 80 years old.

In Q1 2024, the for-profit senior living sector recorded its eleventh quarter in a row of occupancy gains. Based on the past two years of absorption, primary market occupancy recovery should reach pre-pandemic levels in the second half of 20247. As of Q1 2024, primary market occupancy increased 0.5% to 85.6% occupied.

Non-profit senior living has fared better than their for-profit brethren since the pandemic hit. As of Q1 2024, non-profit entrance fee continuing care retirement communities (“CCRC’s”) were 90.6% occupied.

Occupancy recovery has been fueled by over four years of slowing construction starts. In fact, 2023 recorded the lowest primary market inventory growth since 2005, when NIC started recording the data. High interest rates, persistently elevated construction costs and tighter lending conditions will continue to propel occupancy in the months to come. In Q1 2024, primary market inventory growth continued its decline to a mere 1.4% assisted living units and 1.2% independent living units. Given the incredibly low units under construction, the market is setting up for a severe supply and demand imbalance just as the baby boomer population is knocking on the doorstep.

The stark reality is that given the current pace of new senior living development, our country will only supply 40% of the projected demand by 2030. That is an extraordinary shortfall which would require more than $275 billion of investment over the next few years to close the projected demand gap. To put that in context, based on a current development pace of 26,000 new units annually, the industry would need to be running at more than triple the pace to meet the future demand. 7

Anecdotally, NIC Map Vision recently published their Senior Housing Market Outlook, which highlighted the concerning need for significant senior housing growth to keep pace with the unprecedented baby boomer deluge projected in 2027. The timing couldn’t be better as, operationally, most communities have weathered the COVID storm and are showing rent growth and labor market normalization which has led to margin expansion for the first time in years.

From now until 2030, an average of 10,000 baby boomers will turn 65 every day.8 With the combination of increased population and a slow pace of new senior living inventory supply, we are bullish on the critical need to house and care for the impending “Silver Tsunami”.

Concluding thoughts

We continue to stand by our positive long-term outlook for the energy and power and sustainable infrastructure sectors. Opportunities for investing in education and senior living continue to expand for many reasons positioning the sectors well for continued growth.

Energy Infrastructure Corp. (TYG)

 

Fund description

TYG seeks a high level of total return with an emphasis on current distributions paid to stockholders. TYG invests primarily in equity securities in energy infrastructure companies. The fund is positioned to benefit from growing energy demand and accelerated efforts to reduce global CO2 emissions in energy production. Energy infrastructure companies generate, transport and distribute electricity, as well as process, store, distribute and market natural gas, natural gas liquids, refined products and crude oil.

Fund performance

Good earnings reports relative to consensus, continued management discipline toward capital allocation and mergers and acquisitions (M&A), and benign policy implications from Washington drove midstream sector performance higher. Further, midstream’s growing free cash flow, low leverage, inflation protection, and attractive valuation provided a compelling investment backdrop.

Fund structure and distribution policy

The fund is structured to qualify as a Regulated Investment Company (RIC) allowing it to pass-through to shareholders income and capital gains earned, thus avoiding double-taxation. To qualify as a RIC, the fund must meet specific income, diversification and distribution requirements. Regarding income, at least 90 percent of the fund’s gross income must be from dividends, interest and capital gains. The fund must meet quarterly diversification requirements including the requirement that at least 50 percent of the assets be in cash, cash equivalents or other securities with each single issuer of other securities not greater than 5 percent of total assets. No more than 25 percent of total assets can be invested in any one issuer other than government securities or other RIC’s. The fund must also distribute at least 90 percent of its investment company income. RIC’s are also subject to excise tax rules which require RIC’s to distribute approximately 98 percent of net income and net capital gains to avoid a 4 percent excise tax.

The fund has adopted a managed distribution policy (“MDP”). Annual distribution amounts are expected to fall in the range of 7% to 10% of the average week-ending net asset value (“NAV”) per share for the prior fiscal semi-annual period. Distribution amounts will be reset both up and down to provide a consistent return on trailing NAV. Under the MDP, distribution amounts will normally be reset in February and August, with no changes in distribution amounts in May and November.

Leverage

The fund’s leverage utilization increased $0.7 million during the six months ended May 31, 2024, compared to the six months ended November 30, 2023, and represented 20.5% of total assets at May 31, 2024. At year-end, the fund was in compliance with applicable coverage ratios, 74.4% of the leverage cost was fixed, the weighted-average maturity was 1.8 years and the weighted-average annual rate on leverage was 4.19%. These rates will vary in the future as a result of changing floating rates, utilization of the fund’s credit facility and as leverage matures or is redeemed. During the six month period ended May 31, 2024, $14.5 million of Senior Notes were paid in full upon maturity.

Please see the Financial Statements and Notes to Financial Statements for additional detail regarding critical accounting policies, results of operations, leverage, taxes and other important fund information.

2024 Semi-Annual Report | May 31, 2024

Tortoise

Midstream Energy Fund, Inc. (NTG)

 

Fund description

NTG seeks to provide stockholders with a high level of total return with an emphasis on current distributions. NTG invests primarily in midstream energy equities that own and operate a network of pipeline and energy related logistical infrastructure assets with an emphasis on those that transport, gather, process and store natural gas and natural gas liquids (NGLs). NTG targets midstream energy equities, including MLPs benefiting from U.S. natural gas production and consumption expansion, with minimal direct commodity exposure.

Fund performance

Good earnings reports relative to consensus, continued management discipline toward capital allocation and mergers and acquisitions (M&A), and benign policy implications from Washington drove midstream sector performance higher. Further, midstream’s growing free cash flow, low leverage, inflation protection, and attractive valuation provided a compelling investment backdrop. Both dividend growth and opportunistic share repurchases continued. Enthusiasm for artificial intelligence energy demand needs from a significant forecast for new data centers also aided the both the midstream and renewable and power infrastructure sector. The fund’s market-based and NAV-based returns for the fiscal period ending May 31, 2024, were 22.7% and 18.3%, respectively (including the reinvestment of distributions). The Tortoise MLP Index® returned 11.0% during the same period.

Quarterly distributions paid per share $0.7700
Distribution rate (as of 5/31/2024) 7.6%
Year-over-year distribution increase (decrease) 0.0%

2024 Semi-Annual Report | May 31, 2024

Tortoise

Energy Independence Fund, Inc. (NDP)

 

Fund description

NDP seeks a high level of total return with an emphasis on current distributions paid to stockholders. NDP invests primarily in equity securities of upstream North American energy companies that engage in the exploration and production of crude oil, condensate, natural gas and natural gas liquids that generally have a significant presence in North American oil and gas fields, including shale reservoirs.

Fund performance

Good earnings reports relative to consensus, continued management discipline toward capital allocation and mergers and acquisitions (M&A), and benign policy implications from Washington drove broader energy sector performance higher. Further, while geopolitical turmoil continued in both Ukraine and Israel, the energy sector sustained flows from areas of supply to demand centers. The Organization of the Petroleum Exporting Countries Plus (OPEC+) remained constant in their goal to balance crude oil markets. Both dividend growth and opportunistic share repurchases continued. Enthusiasm for artificial intelligence energy demand needs from a significant forecast for new data centers also specifically aided natural gas exposed areas of energy. The fund’s market-based and NAV-based returns for the fiscal period ending May 31, 2024, were 22.0% and 16.4%, respectively (including the reinvestment of distributions).

2024 mid-fiscal year summary  
Quarterly distributions paid per share $0.6300
Distribution rate (as of 5/31/2024) 7.4%
Year-over-year distribution increase (decrease) 0.0%
Cumulative distributions paid per share to stockholders since inception in July 2012 $18.5925
Market-based total return 21.99%
NAV-based total return 16.36%
Premium (discount) to NAV (as of 5/31/2024) (14.4)%

The fund utilizes a covered call strategy when appropriate, which seeks to generate income while reducing overall volatility. No covered calls were written during the period.

Fund structure and distribution policy

The fund is structured to qualify as a Regulated Investment Company (RIC) allowing it to pass-through to shareholders income and capital gains earned, thus avoiding double-taxation. To qualify as a RIC, the fund must meet specific income, diversification and distribution requirements. Regarding income, at least 90 percent of the fund’s gross income must be from dividends, interest and capital gains. The fund must meet quarterly diversification requirements including the requirement that at least 50 percent of the assets be in cash, cash equivalents or other securities with each single issuer of other securities not greater than 5 percent of total assets. No more than 25 percent of total assets can be invested in any one issuer other than government securities or other RIC’s. The fund must also distribute at least 90 percent of its investment company income. RIC’s are also subject to excise tax rules which require RIC’s to distribute approximately 98 percent of net income and net capital gains to avoid a 4 percent excise tax.

The fund has adopted a distribution policy which is included on the inside front cover of this report. To summarize, the fund has adopted a managed distribution policy (“MDP”). Annual distribution amounts are expected to fall in the range of 7% to 10% of the average week-ending net asset value (“NAV”) per share for the prior fiscal semi-annual period. Distribution amounts will be reset both up and down to provide a consistent return on trailing NAV. Under the MDP, distribution amounts will normally be reset in February and August, with no changes in distribution amounts in May and November. The fund may designate a portion of its distributions as capital gains and may also distribute additional capital gains in the last quarter of the year to meet annual excise distribution requirements. Distribution amounts are subject to change from time to time at the discretion of the Board.

Leverage

The fund’s leverage utilization increased $1.4 million, during the six months ended May 31, 2024 as compared to the six months ended November 30, 2023. The fund utilizes all floating rate leverage that had an interest rate of 6.33% and represented 13.3% of total assets at year-end. During the period, the fund maintained compliance with its applicable coverage ratios. The interest rate on the fund’s leverage will vary in the future along with changing floating rates.

Please see the Financial Statements and Notes to Financial Statements for additional detail regarding critical accounting policies, results of operations, leverage and other important fund information.

2024 Semi-Annual Report | May 31, 2024

Ecofin

Sustainable and Social Impact Term Fund (TEAF)

 

Fund description

The Ecofin Sustainable and Social Impact Term Fund (TEAF) seeks to provide a high level of total return with an emphasis on current distributions. TEAF provides investors access to a combination of public and direct investments in essential assets that are making an impact on clients and communities.

Fund Performance

TEAF generated positive performance in the first fiscal half of 2024, the period ranging from November 30 through May 31, with a NAV return of 4.76% and a market return of 2.06%. This compares to global infrastructure (measured by S&P Global Infrastructure Index) which returned 11.73%.

Listed sustainable infrastructure We still believe decarbonization and electrification trends have strong momentum. In Europe as well as in the U.S., power prices were rising, erasing early 2024 falls, and earnings results and guidance were in line with or nicely ahead of consensus expectations, helping to fuel share prices with valuations still relatively low. Additionally, GenAI and datacenters are still supporting the expectation for power demand growth.
Listed energy infrastructure Listed energy infrastructure investments have been positive drivers of performance in the TEAF portfolio. Greater visible demand for natural gas from data center driven artificial intelligence (AI) power needs aided the sector along with continued expectation of U.S. hydrocarbon growth across all energy commodities and the potential for growing exports.
Private social infrastructure closed six new investments during the period and had three realizations. Most of our private investments have performed positively generating stable cash flows in-line with our expectations during the period.
Private sustainable infrastructure investments have had mixed performance with some assets suffering from age related and interconnection issues which are all being worked on to reenergize. Other private sustainable assets continued to perform well and as expected during the quarter.

Most of TEAF’s social infrastructure assets have performed well and we expect that performance to continue to generate stable cash flows. We continue to progress on transitioning the portfolio to the targeted allocation of 60% direct investments. As of May 31, 2024, TEAF’s total direct investment commitments were approximately $108 million or approximately 49% of the portfolio.

Market Overview

Looking ahead to the rest of 2024, we continue to have a constructive outlook for the underlying assets in the TEAF portfolio. We expect that listed sustainable infrastructure equities, TEAF’s largest allocation, may see compelling investment opportunities with valuations at historic lows. Utilities in the portfolio should deliver predictable non-cyclical earnings growth. GenAI and data centers are supporting the expectation for power demand growth. We continue to see that decarbonisation and electrification trends have strong momentum with key drivers such as increasing renewables, manufacturing re-shoring and energy efficiency driving investment. Additionally, corporates and consumers will continue to replace carbon-emitting energy sources with renewables, ensuring renewables growth at a reasonable rate of return. We maintain a positive outlook for energy infrastructure equities through the rest of 2024 driven by favorable fundamentals and a focus on capital return to equity owners.

Listed Energy Infrastructure

Listed energy infrastructure were positive drivers of performance in the TEAF portfolio for the semi-annual fiscal period. Strong equity performance during the period derived from reported earnings at the high end of expectations, prudent allocation of free cash flow toward dividend growth and opportunistic share repurchases, disciplined M&A, and a robust 13% inflation tariff escalator. The energy infrastructure equities also benefitted from the continued expectation of U.S. hydrocarbon growth across all energy commodities and the potential for growing exports. M&A activity was characterized by bolt-on acquisitions from motivated private equity sellers on the asset side. Prices paid were compelling and deals indicated immediate synergies with complementary assets. Greater visible demand for natural gas from data center driven AI power needs also aided the sector. Overall, higher transport volumes, capital allocation favoring shareholders along with low leverage, and constructive energy supply and demand is leading to boosted confidence in energy infrastructure company growth. We think this environment will continue to be supportive of valuation into the remainder of 2024.

Listed Sustainable Infrastructure

From a macro perspective, in late 2023, sustainable infrastructure sectors initially saw some improvement, but by early 2024, utilities and broader infrastructure faced renewed challenges while tech-oriented sectors led market momentum. Expectations of rate cuts faded due to persistent inflation and robust U.S. growth, pushing 10-year bond yields back above 4%. Warm winter weather

and abundant supplies drove down natural gas and power prices in Europe, hindering power generator stocks. In contrast, the U.S. portfolio benefited from strong demand driven by AI, data centers, and EVs, bolstering its performance. March brought a rebound in sentiment and portfolio NAV, supported by hopes of easing inflation and recovering energy prices. Despite uncertainty over interest rates and energy costs, infrastructure valuations showed a modest recovery, though many remained disconnected from growth prospects. In April, despite rising interest rates and 10-year bond yields, listed infrastructure, led by utilities with attractive valuations and strong earnings reports, garnered attention amid a cautious market sentiment favoring defensive assets. The U.S. 10-year Treasury yield reached a year-to-date high of approximately 4.7%, although yield curves remained relatively flat. Regulated utilities and inflation-protected names performed well mid-month, buoyed by increasing recognition as beneficiaries of future data center and AI-driven power demands. American Electric Power highlighted accelerated datacenter opportunities contributing to growth in transmission capex and earnings. Notably, Brookfield’s monumental renewable energy agreement with Microsoft to deliver 10.5 gigawatts (GW) of carbon-free energy underscored the escalating demands from AI, cloud computing, and datacenters. In May, U.S. utilities continued to shine as renewed growth in power demand, particularly from AI-driven datacenters, boosted baseload power producers and transmission utilities in both the U.S. and Europe. Despite European utilities trailing their U.S. counterparts, the portfolio saw robust performances from integrated utilities and environmental services groups. In summary, we continue to look to identify high quality companies with growth prospects and to keep a balance in the portfolio in terms of risk profiles and are positive about the underlaying drivers for the space moving into the second half of fiscal year 2024.

Social Infrastructure

TEAF completed six direct investments in the social impact portfolio during the period.

Dublin Classical Academy (“Dublin”) is a new, public charter school in Dublin, Ohio, just outside of Columbus, slated to open in fall of 2024. The school will utilize the Hillsdale Classical Curriculum. It will serve 462 students in grades K-6 in its inaugural year, with a plan to grow by one grade each year until it reaches grades K-12. Only grades K-8 are contemplated in this phase of the project, with the building’s capacity at 700 students. The school’s charter is authorized by St. Aloysius, with an initial charter term of five years. Dublin’s chosen school site is in the northwest suburbs of Columbus, where there is only one school of choice within five miles, and it does not offer a classical curriculum. Dublin will be the first no-cost classical school in the area. The school board and leader/principal are highly experienced with deep ties to the community. The senior bond investment will be used to acquire, renovate, and equip an existing building, while also providing operating capital for the startup of the school.
Celebration Senior Living of Denison (“Celebration” or “Denison”), a not-for-profit corporation, is acquiring a stabilized senior living facility in Denison, Texas (north of Dallas). The facility has 82 units consisting of 66 assisted living units and 16 memory care units. The building was constructed in 2019 and is well-appointed and modern in design and finishes. Denison has been managed by Restoration Senior Living, LLC since opening in late 2019, which will continue to manage the community following the acquisition. The Manager also operates numerous other senior living communities in Texas, Louisiana, South Carolina, Georgia, and Florida, and has over 25 years of management experience. The investment will be used for subordinated secured bond financing which, combined with senior debt and deeply subordinated junior debt, will allow for the acquisition of the operating facility and funding of multiple reserve funds, including a working capital reserve, liquidity support fund, and a debt service reserve fund specific to these subordinated bonds. The liquidity support fund is further enhanced by personal guarantees.
Northeast Ohio Classical Academy (“NEOCA”) is a new, public charter school in Akron, Ohio, slated to open in fall of 2024. The school will utilize the Hillsdale Classical Curriculum. It will serve 350 students in grades K-5 in its inaugural year, with a plan to grow by one grade each year until it reaches grades K-12. Only grades K-7 are contemplated in this phase of the project, with the building’s capacity at 500 students. The school’s charter is authorized by St. Aloysius, with an initial charter term of five years. NEOCA’s chosen school site is in the very northwest corner of Akron, where there are no schools of choice within five miles. NEOCA will be the first no-cost classical school in the area. The school board and leader/principal are highly experienced with deep ties to the community. The senior secured bond investment will be used to acquire, renovate, and equip an existing building.
Jacaranda Trace Senior Living (“Jac Trace”), a not-for-profit corporation, is an existing Continuing Care Retirement Community (CCRC) located in Venice, FL with a total of 491 living units. There are 436 independent living, 19 assisted living, and 36 memory care units. Prior to this financing, 141 of the IL units were owned independently by the residents of those units. Since the current ownership acquired the property in 2022 (for which Ecofin provided subordinated bond financing), it has planned to acquire those independently-owned units as they become available. The company used existing cash on hand to acquire 6 villas for renovation and redeployment as part of its standard offering. Since acquisition, the property has continued to perform reasonably well, with occupancy near 90% and on track to meet all debt covenants. The investment will be used for subordinated secured bond financing which will allow for the acquisition of the six villas and the funding of a reserve fund specific to these subordinated bonds.

Belton Preparatory Academy is an existing charter school located in Belton, South Carolina that has been operating since 2018 in a temporary location while it seeks its permanent home. Belton Prep offers a classical education curriculum to an underserved population, with great success--as it was recognized as the top academic Title 1 school in the state of South Carolina. The school currently serves approximately 250 students in grades K-6, and will expand to serve K-8 while increasing enrollment over the next 4 years to reach nearly 700 students enrolled. The investment will be used to finish construction and equipping of the building, allowing the school to move in next Fall. This is the third and final scheduled investment.
Lastly, City View Charter School is an existing charter school located in in Hillsboro, Oregon (outside of Portland), looking to consolidate its operations from two leased facilities into a singular, permanent school campus by the end of 2023. The school has been in operation since 2004, and currently serves approximately 315 students in grades K-8. The school is the authorizer’s first and only charter school program. CVCS uses the Expeditionary Learning (“EL”) Education instructional learning model, a unique approach to hands-on, project-based education which has helped the school outperform its local school district as well as the state in ELL, Math, and Science. The demand for the program is evident, as the school has maintained an average waitlist of 280 students for the past 13 years. The senior secured bond investment will be used to acquire, renovate, and equip an existing building. The school expects to begin using a portion of the building immediately for its middle school, with the remaining students moving in once renovations are complete later in the school year.

Finally, the fund had three realizations in H1 2024.

The first realization was in November from a senior living project that raised additional equity to pay off a tranche of subordinated debt. The original investment was made in September 2020 to acquire an existing senior living facility as part of a capital stack that included senior bank debt and two tranches of subordinated bonds. The sponsor determined that the property would be better served with additional equity rather than the Series B subordinated debt which had a 16% coupon. In return for allowing the Series B debt to be paid off, the fund received all accrued and capitalized interest as well as a price of $103. The fund still holds Series A subordinated debt and received a consent fee for allowing the Series B payoff. The facility continues to perform as expected.
The second was in April from a waste-to-energy facility in North Carolina that was able to successfully complete construction and achieve commercial operations. In order to improve its cash flow and obtain additional capital for further expansion, the project obtained take-out and expansion financing. The investment was allowed to be called early at a price of $108.
The last realization, in April, was a charter school that had management and operations problems, ultimately resulting in the school having to sell the property to partially repay the investment.

Private Energy Infrastructure

No deals were completed in the private energy infrastructure portfolio during the period. We continue to have conviction behind greenfield LNG development projects in North America given the geopolitical landscape for natural gas and favorable pricing spread between domestic supply and the global markets. The fund also remains invested in MPL, a 15 million metric tonnes per annum (mmtpa) LNG development project focused on bringing Permian sourced gas to the west coast of Mexico and alleviating the additional transportation costs and time it takes to bring LNG to Asian markets while avoiding Panama Canal congestion.

Private Sustainable Infrastructure

TEAF did not invest in any additional private sustainable infrastructure projects during the period.

EF WWW Holdings (World Water Works) – TEAF’s investment in EF WWW Holdings, LLC, the debt funding of World Water Works Holdings, Inc., has continued to timely pay its annualized interest rate of 10.5% and report strong credit covenants. The company has exceeded its operating budget in every year since the investment, driven by strong backlog and revenue growth.

One Energy – As of April 4, 2024, One Energy will begin controlled restarts of its fleet of wind turbines. On January 22, 2024, a single blade fell from a wind turbine at one of the Company’s projects in Findlay, Ohio. No one was injured by the event and no part of the blade or debris field left the Company’s property. The fleet has not been operating while the Company conducted, with the aid of independent engineers and research institutions, a root cause assessment of the incident and a systematic evaluation of every turbine in its fleet.

The Company has determined that there was an abnormality with the bolted flange assembly that connects the blade to the hub. The issue was not caused by the blade, the internals of the bearing, or the blade bolts. The flange abnormality led to a higher than intended load transfer to the blade bolts which resulted in them fatiguing much faster than designed. The fatigue loads eventually led multiple bolts to have a cascading failure that resulted in the blade completely separating from the turbine and falling to the ground.

The Company has inspected every major bolted flange in each of its wind turbines as part of the investigation. Every single field-installed bolt has had, or will have, its torque rechecked before each turbine begins operating again.

One Energy will begin restarting the turbines in its fleet that do not have the abnormality. The Company is replacing every single blade bolt in the turbines that have or may have an abnormality. The Company is also correcting the abnormality in affected turbines. This 100% bolt replacement will restart the fatigue life of the bolts, and this correction in the flanges assemblies will ensure that the bolts are properly loaded going forward.

In conjunction with the independent engineers and research institutions’ support, the Company has developed new monitoring programs and testing programs that it plans to implement and share with the wind industry. These new methods will allow the Company to gain industry-leading insights into the real-time loads on its bolts and the conditions of its flanges going forward.

TEAF is an investor in One Energy’s 9.00% convertible preferred stock at the corporate/Holdco level. One Energy does not expect this event to have a material effect on its financial performance.

Solar Assets:

Renewable Holdco I, LLC Solar (DG Solar - Portfolio of 14 solar assets across 4 states: CO, FL, NJ and PR) – Energy production at various operating distributed generation (“DG”) solar assets in the Renewable Holdco I, LLC portfolio have underperformed expectations, primarily caused by inverter issues and certain communications equipment failures inherent in the age of the assets and have required corrective maintenance attention. Certain of the small rooftop projects in Puerto Rico within the Renewable Holdco I, LLC portfolio are expected to be reenergized in 2024 after experiencing downtime related to required corrective maintenance. Various third-party inspections and off taker approval are required for these to be reenergized. As such, Ecofin’s internal asset management team is taking an active role in monitoring efforts to restore full energy production and returning the portfolio to stable cash flow generation.

Renewable Holdco II, LLC Solar - (Portfolio of 2 solar projects in MA and CA) – Energy production at the operating DG solar assets in the Renewable Holdco II, LLC portfolio have continued to generate stable cash flow as expected.

Renewable Holdco, LLC (Blackstone Milk Street) – The final solar project under construction, held in Renewable Holdco, LLC, has continued to experience delays due to interconnection redesign, additional permitting and road construction caused by the utility and is expected to be ready for commissioning and commercial operation in H2 2024.

Saturn Solar Bermuda 1 – The construction note has continued to pay its annualized interest rate of 10.0% on time. The payments are supported by cash flow of the now operational solar project since the project completed construction and began full operations in November 2021. The note has remained in place as the owner of the solar facility is seeking to sell the solar project to a new long-term owner/operator.

Fund structure and distribution policy

The fund is structured to qualify as a Regulated Investment Company (RIC) allowing it to pass-through to shareholders income and capital gains earned, thus avoiding double-taxation. To qualify as a RIC, the fund must meet specific income, diversification and distribution requirements. Regarding income, at least 90 percent of the fund gross income must be from dividends, interest and capital gains. The fund must meet quarterly diversification requirements including the requirement that at least 50 percent of the assets be in cash, cash equivalents or other securities with each single issuer of other securities not greater than 5 percent of total assets. No more than 25 percent of total assets can be invested in any one issuer other than government securities or other RIC’s. The fund must also distribute at least 90 percent of its investment company income. RIC’s are also subject to excise tax rules which require RIC’s to distribute approximately 98 percent of net income and net capital gains to avoid a 4 percent excise tax.

The fund has adopted a distribution policy which is included on the inside front cover of this report. To summarize, the fund has adopted a managed distribution policy (“MDP”). Annual distribution amounts are expected to fall in the range of 6% to 8% of the average week-ending net asset value (“NAV”) per share for the prior fiscal semi-annual period. Distribution amounts will be reset both up and down to provide a consistent return on trailing NAV. Under the MDP, distribution amounts will normally be reset in February and August, with no changes in distribution amounts in May and November. The fund may designate a portion of its distributions as capital gains and may also distribute additional capital gains in the last quarter of the year to meet annual excise distribution requirements. Distribution amounts are subject to change from time to time at the discretion of the Board.

Leverage

The fund’s leverage utilization decreased $3.1 million during the six months ended May 31, 2024, as compared to six months ended November 30, 2023. The fund utilizes all floating rate leverage that had an interest rate of 6.33% and represented 9.4% of total assets at year-end. During the period, the fund maintained compliance with its applicable coverage ratios. The interest rate on the fund’s leverage will vary in the future along with changing floating rates.

Please see the Financial Statements and Notes to Financial Statements for additional detail regarding critical accounting policies, results of operations, leverage and other important fund information.

Notes to Financial Statements (unaudited)

May 31, 2024

1. General Organization

This report covers the following companies, each of which is listed on the New York Stock Exchange (“NYSE”): Tortoise Energy Infrastructure Corp. (“TYG”), Tortoise Midstream Energy Fund, Inc. (“NTG”), Tortoise Pipeline & Energy Fund, Inc. (“TTP”), Tortoise Energy Independence Fund, Inc. (“NDP”), Tortoise Power and Energy Infrastructure Fund, Inc. (“TPZ”), and Ecofin Sustainable and Social Impact Term Fund (“TEAF”). These companies are individually referred to as a “Fund” or by their respective NYSE symbols, or collectively as the “Funds”, and each is a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). Each of TYG, NTG, TTP, NDP and TEAF has a primary investment objective to seek a high level of total return with an emphasis on current distributions. TPZ has a primary investment objective to provide a high level of current income, with a secondary objective of capital appreciation.

2. Significant Accounting Policies

The Funds are investment companies and follow accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. These policies are in conformity with generally accepted accounting principles in the United States of America (“GAAP”).

A. Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and the amount of income and expenses during the period reported. Actual results could differ from those estimates.

B. Security Valuation

In general, and where applicable, the Funds use readily available market quotations based upon the last updated sales price from the principal market to determine fair value. The Funds primarily own securities that are listed on a securities exchange or are traded in the over-the-counter market. The Funds value those securities at their last sale price on that exchange or over-the-counter market on the valuation date. If the security is listed on more than one exchange, the Funds use the price from the exchange that it considers to be the principal exchange on which the security is traded. If there has been no sale on such exchange or over-the-counter market on such day, the security is valued at the mean between the last bid price and last ask price on such day. Securities listed on the NASDAQ are valued at the NASDAQ Official Closing Price, which may not necessarily represent the last sale price. These securities are categorized as Level 1 in the fair value hierarchy.

Restricted securities are subject to statutory or contractual restrictions on their public resale, which may make it more difficult to obtain a valuation and may limit a Fund’s ability to dispose of them. Investments in private placement securities and other securities for which market quotations are not readily available are valued in good faith by using fair value procedures. Such fair value procedures consider factors such as discounts to publicly traded issues, time until conversion date, securities with similar yields, quality, type of issue, coupon, duration and rating. If events occur that affect the value of a Fund’s portfolio securities before the net asset value has been calculated (a “significant event”), the portfolio securities so affected are generally priced using fair value procedures.

An equity security of a publicly traded company acquired in a private placement transaction without registration under the Securities Act of 1933, as amended (the “1933 Act”), is subject to restrictions on resale that can affect the security’s liquidity and fair value. If such a security is convertible into publicly traded common shares, the security generally will be valued at the common share market price adjusted by a percentage discount due to the restrictions and categorized as Level 2 in the fair value hierarchy. To the extent that such securities are convertible or otherwise become freely tradable within a time frame that may be reasonably determined, an amortization schedule may be used to determine the discount. If the security has characteristics that are dissimilar to the class of security that trades on the open market, the security will generally be valued and categorized as Level 3 in the fair value hierarchy.

Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity. Unobservable inputs reflect the Funds’ own beliefs about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). Unobservable inputs are developed based on the best information available in the circumstances, which might include the Fund’s own data. The Fund’s own data are adjusted if information is reasonably available without undue cost and effort that indicates that market participants would use different assumptions. Due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed.

Options (including options on futures contracts) and futures contracts are valued using readily available market quotations. Exchange-traded options are valued at the last reported sale price on any exchange on which they trade. If there are no sales reported on any exchange, exchange-traded options shall be valued at the mean between the last highest bid and last lowest asked prices obtained as of the closing of the exchanges on which the option is traded. Exchange-traded domestic futures contracts are valued at the last reported sale price on the Chicago Mercantile Exchange. Exchange-traded foreign futures contracts are valued at the last reported sale price on the primary foreign exchange on which they principally trade. The value of Flexible Exchange Options (FLEX Options) are determined (i) by an evaluated price as determined by a third-party valuation service; or (ii) by using a quotation provided by a broker-dealer.

2024 Semi-Annual Report | May 31, 2024

Notes to Financial Statements (unaudited) (continued)

The Funds generally value debt securities at evaluated prices obtained from an independent third-party valuation service that utilizes a pricing matrix based upon yield data for securities with similar characteristics, or based on a direct written broker-dealer quotation from a dealer who has made a market in the security. Debt securities with 60 days or less to maturity at time of purchase are valued on the basis of amortized cost, which approximates fair value. The securities are categorized as level 2 in the fair value hierarchy.

Interest rate swap contracts are valued by using industry-accepted models, which discount the estimated future cash flows based on a forward rate curve and the stated terms of the interest rate swap agreement by using interest rates currently available in the market, or based on dealer quotations, if available, and are categorized as Level 2 in the fair value hierarchy.

Various inputs are used in determining the fair value of the Funds’ investments and financial instruments. These inputs are summarized in the three broad levels listed below:

Level 1 — quoted prices in active markets for identical investments

Level 2 — other significant observable inputs (including quoted prices for similar investments, market corroborated inputs, etc.)

Level 3 — significant unobservable inputs (including a Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following tables provide the fair value measurements of applicable assets and liabilities by level within the fair value hierarchy as of May 31, 2024. These assets and liabilities are measured on a recurring basis.

TEAF owns units of preferred stock of One Energy Enterprises Inc. (“One Energy Pfd”) that were issued in a transaction that closed on April 12, 2023. One Energy Enterprises Inc. is a private company. The preferred stock carries a conversion option into common stock on and after the earlier to occur of (i) the closing of a DeSPAC, (ii) the consummation of an IPO or (iii) the effectiveness of a direct listing in which the Common Stock becomes listed on a national securities exchange (such date the “Initial Liquidity Date”). A discounted cash flow model prepared by an independent third party is being used to determine fair value of the One Energy Pfd security. Unobservable inputs used to determine the discount rate include a debt discount rate that generally reflects the credit worthiness of the company. An increase (decrease) in the debt discount rate would lead to a corresponding decrease (increase) in fair value of the preferred stock.

TEAF owns units of Mexico Pacific Limited LLC (“MPL”), which was issued in a private transaction that closed on October 23, 2019. As of November 30, 2023, the investment in MPL was valued at the most recent transaction price, which was a capital raise that closed on September 30, 2021, as the company is still in development with no day-to-day operations.

TEAF owns a private note in Saturn Solar Bermuda 1, Ltd (“Saturn”). Under the terms of the note, Saturn pays interest monthly at an annual rate of 10%. A discounted cash flows model is being utilized to determine fair value of the private note. Unobservable inputs used to determine the discount rate include a risk spread based on similar projects and an illiquidity spread due to the note being issued in the private market. An increase (decrease) in the risk spread or illiquidity spread would lead to a corresponding decrease (increase) in fair value of the note.

TEAF owns a note in EF WWW Holdings, LLC, for debt funding of World Water Works Holdings, Inc. Under the terms of the note, EF WWW Holdings pays interest monthly at an annual rate of 10.50%. A discounted cash flows model is being utilized to determine fair value of the private note. Unobservable inputs used to determine the discount rate include a risk spread based on similar projects and an illiquidity spread due to the note being issued in the private market. An increase (decrease) in the risk spread or illiquidity spread would lead to a corresponding decrease (increase) in fair value of the note.

TYG wholly-owns private investments in TK NYS Solar Holdco, LLC and TEAF wholly-owns private investments in Renewable Holdco, LLC, Renewable Holdco I, LLC, and Renewable Holdco II, LLC. Discounted cash flow models are being utilized to determine the fair value of these holdings. Unobservable inputs used within the discounted cash flow models include weighted average cost of capital. An increase (decrease) in the weighted average cost of capital would lead to a corresponding decrease (increase) in the fair value of the private investment.

TEAF owns a private corporate bond in Contour Propco. A discounted cash flows model is being utilized to determine fair value of the private bond. Unobservable inputs used to determine the discount rate include a risk spread based on similar projects and an illiquidity spread due to the bond being issued in the private market. An increase (decrease) in the risk spread or illiquidity spread would lead to a corresponding decrease (increase) in fair value of the bond.

TEAF owns a municipal bond in Ohio Public Finance Authority, 12.00%, 12/15/2053, Obligor Heart of America Classical Foundation, which was issued in a private transaction that closed on May 30, 2024. As of May 31, 2024, the investment in the private municipal bond was valued at the most recent transaction price, and thus held at cost.

The following tables summarize the fair value and significant unobservable inputs that each Fund used to value its portfolio investments categorized as Level 3 as of May 31, 2024:

C. Securities Transactions and Investment Income

Securities transactions are accounted for on the date the securities are purchased or sold (trade date). Realized gains and losses are reported on an identified cost basis. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts. Discounts and premiums on fixed income securities are amortized or accreted over the life of the respective securities using the effective interest method. Dividend income and distributions are recorded on the ex-dividend date. Distributions received from investments generally are comprised of ordinary income and return of capital. The Funds estimate the allocation of distributions between investment income and return of capital at the time such distributions are received based on historical information or regulatory filings. These estimates may subsequently be revised based on actual allocations received from the portfolio companies after their tax reporting periods are concluded, as the actual character of these distributions is not known until after the fiscal year-end of the Funds.

2024 Semi-Annual Report | May 31, 2024

Notes to Financial Statements (unaudited) (continued)

Subsequent to November 30, 2023, the Funds reallocated the amount of return of capital recognized for the period from December 1, 2022 through November 30, 2023 based on the 2023 tax reporting information received. The impact of this reclass is as follows:

   Estimated Return
of Capital %
  Revised Return
of Capital %
  Increase/(Decrease)
in Return of Capital
TYG   48%   51%  $814,394 
NTG   52%   57%  $855,789 
TTP   53%   51%  $(100,821)
NDP   32%   36%  $137,444 
TPZ   72%   69%  $(115,875)
TEAF   37%   37%  $(2,281)

In addition, the Funds may be subject to withholding taxes on foreign-sourced income. The Funds accrue such taxes when the related income is earned in accordance with the Funds’ understanding of the applicable country’s tax rules and rates.

D. Foreign Currency Translation

For foreign currency, investments in foreign securities, and other assets and liabilities denominated in a foreign currency, the Funds translate these amounts into U.S. dollars on the following basis: (i) market value of investment securities, assets and liabilities at the current rate of exchange on the valuation date, and (ii) purchases and sales of investment securities, income and expenses at the relevant rates of exchange on the respective dates of such transactions. The Funds do not isolate the portion of gains and losses on investments that is due to changes in the foreign exchange rates from that which is due to changes in market prices of securities.

E. Federal and State Income Taxation

The Funds each qualify as a regulated investment company (“RIC”) under the Internal Revenue Code (“IRC”). As a result, the Funds generally will not be subject to U.S. federal income tax on income and gains that they distribute each taxable year to stockholders if they meet certain minimum distribution requirements. However, TEAF’s taxable subsidiary, created to hold certain investments is generally subject to federal and state income taxes on its income. RICs are required to distribute substantially all of their income, in addition to meeting certain asset diversification requirements, and are subject to a 4% non-deductible U.S. federal excise tax on certain undistributed income unless the fund makes sufficient distributions to satisfy the excise tax avoidance requirement.

The Funds recognize the tax benefits of uncertain tax positions only when the position is “more likely than not” to be sustained upon examination by the tax authorities based on the technical merits of the tax position. The Funds’ policy is to record interest and penalties on uncertain tax positions as part of tax expense.

As of May 31, the Funds had no uncertain tax positions, and no penalties or interest was accrued. The Funds do not expect any change in their unrecognized tax positions in the next twelve months. The tax years ended November 30, 2020 through 2023 remain open to examination by federal and state tax authorities.

F. Distributions to Stockholders

Distributions to common stockholders are recorded on the ex-dividend date. The Funds may not declare or pay distributions to its common stockholders if it does not meet asset coverage ratios required under the 1940 Act or the rating agency guidelines for its debt and preferred stock following such distribution. The amount of any distributions will be determined by the Board of Directors. The character of distributions to common stockholders made during the year may differ from their ultimate characterization for federal income tax purposes.

As RICs, the Funds each intend to make cash distributions of its investment company taxable income and capital gains to common stockholders. In addition, on an annual basis, the Funds each may distribute additional capital gains in the last calendar quarter if necessary to meet minimum distribution requirements and thus avoid being subject to excise taxes. Distributions paid to stockholders in excess of investment company taxable income and net realized gains will be treated as return of capital to stockholders.

Distributions to mandatory redeemable preferred (“MRP”) stockholders are accrued daily based on applicable distribution rates for each series and paid periodically according to the terms of the agreements. The Funds may not declare or pay distributions to its preferred stockholders if it does not meet a 200% asset coverage ratio for its debt or the rating agency basic maintenance amount for the debt following such distribution. The character of distributions to preferred stockholders made during the year may differ from their ultimate characterization for federal income tax purposes.

Notes to Financial Statements (unaudited) (continued)

Distributions to stockholders for the year ended November 30, 2023 were characterized as follows:

   TYG  NTG  TTP  NDP  TPZ  TEAF
   Common  Preferred  Common  Preferred  Common  Preferred  Common  Common  Common
Qualified dividend income   40%    70%   46%   86%   22%   100%   30%   16%   31%
Ordinary dividend income   18%   30%   7%   14%               33%   2%
Return of capital   42%       47%       78%   0%   70%   51%   67%
Long-term capital gain                                    

* For Federal income tax purposes, distributions of short-term capital gains are included in qualified dividend income.

G. Offering and Debt Issuance Costs

Offering costs related to the issuance of common stock are charged to additional paid-in capital when the stock is issued. Debt issuance costs related to senior notes and MRP Stock are deferred and amortized over the period the debt or MRP Stock is outstanding.

There were no offering or debt issuance costs recorded during the period December 1, 2023 through May 31, 2024 for TYG, NTG, TTP, NDP, TPZ or TEAF.

H. Derivative Financial Instruments

The Funds have established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. The Funds do not hold or issue derivative financial instruments for speculative purposes. All derivative financial instruments are recorded at fair value with changes in fair value during the reporting period, and amounts accrued under the agreements, included as unrealized gains or losses in the accompanying Statements of Operations. Derivative instruments that are subject to an enforceable master netting arrangement allow a Fund and the counterparty to the instrument to offset any exposure to the other party with amounts owed to the other party. The fair value of derivative financial instruments in a loss position are offset against the fair value of derivative financial instruments in a gain position, with the net fair value appropriately reflected as an asset or liability within the accompanying Statements of Assets & Liabilities.

TYG, NTG, TTP, NDP and TEAF may seek to provide current income from gains earned through an option strategy that normally consists of writing (selling) call options on selected equity securities held in the portfolio (“covered calls”). The premium received on a written call option is initially recorded as a liability and subsequently adjusted to the then current fair value of the option written. Premiums received from writing call options that expire unexercised are recorded as a realized gain on the expiration date. Premiums received from writing call options that are exercised are added to the proceeds from the sale of the underlying security to calculate the realized gain (loss). If a written call option is repurchased prior to its exercise, the realized gain (loss) is the difference between the premium received and the amount paid to repurchase the option.

TEAF may enter into forward currency contracts, which represent agreements to exchange currencies on specific future dates at predetermined rates. TEAF uses forward currency contracts to manage exposure to changes in exchange rates. On a daily basis, TEAF’s investment adviser values forward currency contracts and records unrealized appreciation or depreciation for open forward currency contracts in the Statements of Assets & Liabilities. Realized gains or losses are recorded at the time the forward currency contracts are closed. TEAF did not enter into any forward currency contracts during the period ended May 31, 2024.

I. Indemnifications

Under each of the Funds’ organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds may enter into contracts that provide general indemnification to other parties. A Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Funds that have not yet occurred, and may not occur. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote.

J. Cash and Cash Equivalents

Cash and cash equivalents include short-term, liquid investments with an original maturity of three months or less and money market fund accounts.

2024 Semi-Annual Report | May 31, 2024

K. Recent Accounting and Regulatory Updates

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04 Reference Rate Reform (Topic 848); Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform. The guidance is applicable to contracts referencing London Interbank Offered Rate (“LIBOR”) or another reference rate that is expected to be discontinued due to reference rate reform. The original guidance and the scope clarification become effective upon issuance in March 2020 and January 2021, respectively. However, the guidance in ASC 848 is temporary in nature and generally cannot be applied to contract modifications that occur after December 31, 2022 or hedging relationships entered into or evaluated after that date. In December 2022, FASB deferred ASU 2022-04 and issued ASU 2022-06, Reference Rate Reform: Deferral of the Sunset Date of Topic 848, which extends the application of the amendments through December 31, 2024. Management is evaluating and believes it is unlikely the ASU’s adoption will have a significant impact on the Fund’s financial statements.

The FASB issued final guidance (ASU No. 2022-08) to clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered when measuring fair value. Recognizing a contractual restriction on the sale of an equity security as a separate unit of account is not permitted. The guidance applies to all entities that have investments in equity securities measured at fair value that are subject to contractual sale restrictions. Entities that hold equity securities subject to contractual sale restrictions are required to make additional disclosures. The guidance will be applied prospectively, with special transition provisions for entities that qualify as investment companies under ASC 946. For public business entities, the guidance is effective for fiscal years beginning after 15 December 2023, and interim periods within those fiscal years. Management is currently assessing the potential impact of the new guidance on the Funds’ financial statements.

3. Risks and Uncertainties

TYG, NTG, TTP, NDP and TPZ concentrate their investments in the energy sector. TEAF concentrates its investments in issuers operating in essential asset sectors. Funds that primarily invest in a particular sector may experience greater volatility than companies investing in a broad range of industry sectors. A Fund may, for defensive purposes, temporarily invest all or a significant portion of its assets in investment grade securities, short-term debt securities and cash or cash equivalents. To the extent a Fund uses this strategy, it may not achieve its investment objective.

4. Agreements

The Funds have each entered into an Investment Advisory Agreement with Tortoise Capital Advisors, L.L.C. (the “Adviser”). The Funds each pay the Adviser a fee based on the Fund’s average monthly total assets (including any assets attributable to leverage and excluding any net deferred tax asset) minus accrued liabilities (other than net deferred tax liability, debt entered into for purposes of leverage and the aggregate liquidation preference of outstanding preferred stock) (“Managed Assets”), in exchange for the investment advisory services provided. Average monthly Managed Assets is the sum of the daily Managed Assets for the month divided by the number of days in the month.

5. Income Taxes

TYG and NTG:

It is the intention of TYG and NTG to qualify as RICs under Subchapter M of the IRC and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements, except as discussed below.

For the period ending May 31, 2024, TYG and NTG have a net tax expense of $139,209 and $18,024 respectively, relating to prior periods in which they were C Corporations (TYG: $139,209; NTG: $18,024), and built-in gains taxes related to the conversion transaction (TYG: $0; NTG: $0). TYG and NTG are expected to be subject to federal income tax on any built-in gains recognized related to the conversion transaction (as described below) during its fiscal year ending November 30, 2024, but do not expect to be subject to excise tax during calendar year ending December 31, 2024.

Income taxes relating to prior periods in which TYG and NTG were subject to tax as C Corporations are being calculated by applying the federal rate plus a blended state income tax rate of approximately 23%.

As part of the conversion transaction, TYG and NTG may be subject to corporate level-tax on the net unrecognized built-in gains inherent on the conversion date recognized during the subsequent 5-year period which ends November 30, 2027 (“the recognition period”). The conversion transaction requires TYG and NTG to track built-in gains throughout the recognition period and potentially pay a corporate-level tax on any built-in gains recognized. During the recognition period, tax is imposed on the lesser of the net built-in gain recognized, the taxable income as if the Fund were a corporation or the net unrealized built-in gain at the conversion date. If the unrecognized built-in gains are recognized in the recognition period, the Funds calculate tax based on the lesser of these three calculations and utilize pre-conversion capital loss carryforwards, it is possible that the sale of the conversion property will not result in a current tax liability. Therefore, each year during the recognition period, TYG and NTG will determine if any of these built-in gains have been recognized, such gain is not offset by the capital loss carryforwards and calculate tax accordingly. If a tax liability is generated, TYG and NTG will record the current tax liability and current tax expense in the period in which it is incurred. After the recognition period has ended, any built-in gains recognized will no longer be subject to corporate-level tax.

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax purposes. The difference between the financial reporting basis and the tax basis of the investment in the MLP investments (i.e., the outside basis difference) may create a taxable temporary difference or a deductible temporary difference. In measuring and determining the character of the tax consequences of the outside basis differences in its MLP investments, the Funds consider the expected types of taxable or deductible amounts in future years and have concluded that the nature of the outside basis differences are capital in character because the Funds do not have the ability to control the MLPs’ investment, distribution, or allocation decisions and, therefore, expect to recover the outside basis differences upon disposal of the interests in the MLPs, which are considered capital assets in accordance with the tax law. The conversion transaction does not impose or trigger a sale of securities held by TYG or NTG as of the conversion date. TYG and NTG do not estimate or forecast future events, including the potential recharacterization of capital gains as ordinary income associated with selling MLP investments when evaluating their deferred income taxes. The sale of MLP unit typically results in the recognition of a capital gain or loss. In accordance with the tax law, a portion of any gain or loss recognized by the Funds may be recharacterized as ordinary income (“recapture”) to the extent attributable to assets of the MLP that give rise to depreciation recapture in the recognition period. Any such gain may exceed the net taxable gain realized on the sale and will be recognized regardless of whether there is a net taxable gain or loss on the sale of such unit. The Funds will record any current and deferred taxes as appropriate.

Components of TYG’s and NTG’s deferred tax assets and liabilities as of May 31, 2024 are as follows:

   TYG   NTG 
Deferred tax assets:          
Capital loss carryforwards  $17,636,498   $6,444,434 
    17,636,498    6,444,434 
Deferred tax liabilities:          
Net unrealized gain on investment securities   17,636,498    6,444,434 
    17,636,498    6,444,434 
Total net deferred tax liability (asset)  $   $ 

The amount and character of income and capital gain distributions to be paid, if any, are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. These differences are primarily due to return of capital distributions, book/tax differences from underlying investments and the timing of recognition of gains or losses on investments.

2024 Semi-Annual Report | May 31, 2024

Notes to Financial Statements (unaudited) (continued)

As of November 30,2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

   TYG   NTG 
Unrealized appreciation (depreciation)  $39,123,613   $24,096,912 
Capital loss carryforwards   (257,000,023)   (460,471,361)
Undistributed ordinary income        
Other temporary differences   (580,908)   (161,479)
Accumulated earnings (deficit)  $(218,457,318)  $(436,535,928)

As of November 30, 2023, for federal income tax purposes, TYG and NTG had capital loss carryforwards of approximately $257,000,000 and $461,000,000 respectively, which may be carried forward for 5 years. If not utilized, these capital losses will expire in the year ending November 30, 2025. Because of TYG and NTG’s intent to be subject to tax as a RIC, any temporary differences such as capital loss carryforwards from periods in which each fund was a C-Corporation must be further evaluated to determine what the expected future tax rate would be upon reversal. As such, TYG and NTG expect capital loss carryforwards of $84,592,032 and $32,854,042 respectively, to reverse at 21%, the tax rate applicable to built-in gains that were generated when the funds were C-Corporations. The remaining capital loss carryforwards are expected to reverse at 0%, the tax rate applicable to RICs.

As of May 31, 2024, TYG and NTG generated approximately $4,800,000 and $2,800,000 of capital loss carryforwards in the current year.

As of May 31, 2024, the aggregate cost of investments, aggregate gross unrealized appreciation and aggregate gross unrealized depreciation on a federal income tax basis were as follows:

   TYG   NTG 
Tax cost of investments  $438,068,009   $237,648,186 
Gross unrealized appreciation of investments  $146,843,097   $77,032,937 
Gross unrealized depreciation of investments   (31,157,282)   (10,613,225)
Net unrealized appreciation (depreciation) of investments  $115,685,815   $66,419,712 

TTP, NDP, TPZ and TEAF:

It is the intention of TTP, NDP, TPZ and TEAF to qualify as RICs under Subchapter M of the IRC and distribute all of its taxable income. Accordingly, no provision for federal income taxes is required in the financial statements. However, TEAF’s taxable subsidiary created to make and hold certain investments is generally subject to federal and state income taxes on its income.

As of May 31, 2024, TEAF consolidated the balance of a deferred tax expense of $0 related to the investment activities of its taxable subsidiary. Total income taxes are computed by applying the federal statutory rate plus a blended state income tax rate totaling 25.62%.

At May 31, 2024, a valuation allowance on deferred tax assets was necessary because TEAF believes it is not more likely than not that its able to realize its deferred tax assets through future taxable income. TEAF has recorded a valuation allowance of $2,306,101. Any adjustments to TEAF’s estimates of future taxable income will be made in the period such determination is made.

Total income tax expense for TEAF’s taxable subsidiary differs from the amount computed by applying the federal statutory income tax rate of 21% to net income for the period ended May 31, 2024, as follows:

Application of Statutory Income tax rate  $(859,384)        
State Income taxes, net of federal tax effect   (188,960)        
Permanent differences   4,597         
Other            
Change in valuation allowance   1,043,747         
Total income tax benefit  $         

The amount and character of income and capital gain distributions to be paid, if any, are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. The sale of a MLP unit results in the recognition of a capital gain or loss with a portion of any gain or loss recognized by the Funds subject to being treated as ordinary income to the extent attributable to assets of the MLP that give rise to depreciation recapture. Any such gain may exceed the net taxable gain realized on the sale and will be recognized regardless of whether there is a net taxable gain or loss on the sale of such unit. As such, net, ordinary gains recognized upon the sale of MLP units may change the character of distributions to shareholders. These differences are primarily due to return of capital distributions and book/tax differences from underlying investments.

As of November 30, 2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

   TTP   NDP   TPZ   TEAF 
Unrealized appreciation (depreciation)  $(42,908)  $19,617,973   $6,402,962   $(6,607,080)

Accumulated earnings (deficit)  $(95,843,087)  $(150,359,324)  $(3,497,191)  $(33,742,878)

(1) Primarily related to losses deferred under straddle regulations per IRC Sec. 1092.

As of November 30, 2023, TTP, NDP, TPZ and TEAF had short-term capital loss carryforwards of $16,580,238, $69,928,235, $202,707, and $22,613,457 respectively, and TTP, NDP, TPZ and TEAF had long-term capital loss carryforwards of $79,159,111, $100,049,062, $9,695,844, and 4,195,117 respectively, which may be carried forward for an unlimited period under the Regulated Investment Company Modernization Act of 2010. To the extent future net capital gains are realized, those gains will be offset by any unused capital loss carryforwards. Capital loss carryforwards will retain their character as either short-term or long-term capital losses. Thus, such losses must be used first to offset gains of the same character; for example, long-term loss carryforwards will first offset long-term gains, before they can be used to offset short-term gains.

As of May 31, 2024 TTP, NDP, TPZ and TEAF utilized (generated) approximately $(125,000), $180,000, $(1,145,000) and $832,000 of capital loss carryforwards in the current year.

In order to meet certain excise tax distribution requirements, TTP, NDP, TPZ and TEAF are required to measure and distribute annually net capital gains realized during a twelve month period ending October 31 and net investment income earned during a twelve month period ending December 31. In connection with this, TTP, NDP, TPZ and TEAF are permitted for tax purposes to defer into their next fiscal year, qualified late year losses. Qualified late year ordinary losses are any net ordinary losses incurred between January 1 and the end of their fiscal year, November 30, 2023. For the taxable year ended November 30, 2023, TTP, NDP, TPZ and TEAF do not plan to defer any losses.

As of May 31, 2024, the aggregate cost of investments, aggregate gross unrealized appreciation and aggregate gross unrealized depreciation on a federal income tax basis were as follows:

   TTP   NDP   TPZ   TEAF 
Tax cost of investments  $65,421,317   $44,739,557   $96,224,335   $223,525,996 
Gross unrealized appreciation of investments  $32,918,023   $31,612,850   $34,922,208   $20,763,672 
Gross unrealized depreciation of investments   (2,132,357)   (110,035)   (3,299,997)   (24,483,904)
Net unrealized appreciation (depreciation) of investments  $30,785,666   $31,502,815   $31,622,211   $(3,720,232)

9. Senior Notes

TYG, NTG and TTP each have issued private senior notes (collectively, the “Notes”), which are unsecured obligations and, upon liquidation, dissolution or winding up of a Fund, will rank: (1) senior to all of the Fund’s outstanding preferred shares, if any; (2) senior to all of the Fund’s outstanding common shares; (3) on parity with any unsecured creditors of the Fund and any unsecured senior securities representing indebtedness of the Fund and (4) junior to any secured creditors of the Fund. Holders of the Notes are entitled to receive periodic cash interest payments until maturity. The Notes are not listed on any exchange or automated quotation system.

The Notes are redeemable in certain circumstances at the option of a Fund, subject to payment of any applicable make-whole amounts or early redemption premiums. The Notes for a Fund are also subject to a mandatory redemption if the Fund fails to meet asset coverage ratios required under the 1940 Act or the rating agency guidelines if such failure is not waived or cured. At May 31, 2024, each of TYG, NTG and TTP were in compliance with asset coverage covenants and basic maintenance covenants for its senior notes.

Details of each Fund’s outstanding Notes, including estimated fair value, as of May 31, 2024 are included below. The estimated fair value of each series of fixed-rate Notes was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, plus either 1) the spread between the interest rate on recently issued debt and the U.S. Treasury rate with a similar maturity date or 2) if there has not been a recent debt issuance, the spread between the AAA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date plus the spread between the fixed rates of the Notes and the AAA corporate finance debt rate. The estimated fair value of floating rate Notes approximates the carrying amount because the interest rate fluctuates with changes in interest rates available in the current market. The estimated fair values in the following tables are Level 2 valuations within the fair value hierarchy.

10. Mandatory Redeemable Preferred Stock

TYG, NTG and TTP each have issued and outstanding MRP Stock at May 31, 2024. The MRP Stock has rights determined by the Board of Directors. Except as otherwise indicated in the Funds’ Charter or Bylaws, or as otherwise required by law, the holders of MRP Stock have voting rights equal to the holders of common stock (one vote per MRP share) and will vote together with the holders of shares of common stock as a single class except on matters affecting only the holders of preferred stock or the holders of common stock. The 1940 Act requires that the holders of any preferred stock (including MRP Stock), voting separately as a single class, have the right to elect at least two directors at all times.

Under the 1940 Act, a Fund may not declare dividends or make other distributions on shares of common stock or purchases of such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding MRP Stock would be less than 200%. The MRP Stock is also subject to a mandatory redemption if a Fund fails to meet an asset coverage ratio of at least 225% as determined in accordance with the 1940 Act or a rating agency basic maintenance amount if such failure is not waived or cured. At May 31, 2024, each of TYG, NTG and TTP were in compliance with asset coverage covenants and basic maintenance covenants for its MRP Stock.

Details of each Fund’s outstanding MRP Stock, including estimated fair value, as of May 31, 2024 is included below. The estimated fair value of each series of TYG, NTG and TTP MRP Stock was calculated for disclosure purposes by discounting future cash flows at a rate equal to the current U.S. Treasury rate with an equivalent maturity date, plus either 1) the spread between the interest rate on recently issued preferred stock and the U.S. Treasury rate with a similar maturity date or 2) if there has not been a recent preferred stock issuance, the spread between the AA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date plus the spread between the fixed rates of the MRP Stock and the AA corporate finance debt rate. The estimated fair values of each series of the TYG, NTG and TTP MRP Stock are Level 2 valuations within the fair value hierarchy.

TYG:

TYG has 65,000,000 shares of preferred stock authorized and 3,566,061 shares of MRP Stock outstanding at May 31, 2024. TYG’s MRP Stock has a liquidation value of $10.00 per share plus any accumulated but unpaid distributions, whether or not declared.

12. Derivative Financial Instruments

The Funds have adopted the disclosure provisions of FASB Accounting Standard Codification 815, Derivatives and Hedging (“ASC 815”). ASC 815 requires enhanced disclosures about the Funds’ use of and accounting for derivative instruments and the effect of derivative instruments on the Funds’ results of operations and financial position. Tabular disclosure regarding derivative fair value and gain/loss by contract type (e.g., interest rate contracts, foreign exchange contracts, credit contracts, etc.) is required and derivatives accounted for as hedging instruments under ASC 815 must be disclosed separately from those that do not qualify for hedge accounting. Even though the Funds may use derivatives in an attempt to achieve an economic hedge, the Funds’ derivatives are not accounted for as hedging instruments under ASC 815 because investment companies account for their derivatives at fair value and record any changes in fair value in current period earnings.

Forward Currency Contracts

TEAF may invest in derivative instruments for hedging or risk management purposes, and for short-term purposes such as maintaining market exposure pending investment of the proceeds of an offering or transitioning its portfolio between different asset classes. The Fund’s use of derivatives could enhance or decrease the cash available to the Fund for payment of distributions or interest, as the case may be. Derivatives can be illiquid, may disproportionately increase losses and have a potentially large negative impact on the Fund’s performance. Derivative transactions, including options on securities and securities indices and other transactions in which the Fund may engage (such as forward currency transactions, futures contracts and options thereon and total return swaps), may subject the Fund to increased risk of principal loss due to unexpected movements in stock prices, changes in stock volatility levels, interest rates and foreign currency exchange rates and imperfect correlations between the Fund’s securities holdings and indices upon which derivative transactions are based. The Fund also will be subject to credit risk with respect to the counterparties to any OTC derivatives contracts the Fund enters into.

As of May 31, 2024, TEAF held no forward currency contracts.

Interest Rate Swap Contracts

TYG may enter into interest rate swap contracts in an attempt to protect it from increasing interest expense on its leverage resulting from increasing interest rates. A decline in interest rates may result in a decline in the value of the swap contracts, which may result in a decline in the net assets of TYG. At the time the interest rate swap contracts reach their scheduled termination, there is a risk that TYG will not be able to obtain a replacement transaction, or that the terms of the replacement would not be as favorable as on the expiring transaction. In addition, if TYG is required to terminate any swap contract early due to a decline in net assets below a threshold amount or failing to maintain a required 300% asset coverage of the liquidation value of the outstanding debt, then TYG could be required to make a payment to the extent of any net unrealized depreciation of the terminated swaps, in addition to redeeming all or some of its outstanding debt. TYG segregates a portion of its assets as collateral for the amount of any net liability of its interest rate swap contracts.

TYG may be subject to credit risk on the interest rate swap contracts if the counterparty should fail to perform under the terms of the interest rate swap contracts. The amount of credit risk is limited to the net appreciation of the interest rate swap contracts, if any, as no collateral is pledged by the counterparty. In addition, if the counterparty to the interest rate swap contracts defaults, the Fund would incur a loss in the amount of the receivable and would not receive amounts due from the counterparty to offset the interest payments on the Fund’s leverage. As of May 31, 2024, TYG held no interest rate swap contracts.

Additional Information (unaudited) (continued)

Automatic Dividend Reinvestment

Each of NTG, TTP, NDP and TPZ have an Automatic Dividend Reinvestment Plan and TYG has an Automatic Dividend Reinvestment and Cash Purchase Plan (each, a “Plan”). Each Plan allows participating common stockholders to reinvest distributions, including dividends, capital gains and return of capital in additional shares of the Fund’s common stock and TYG’s Plan also allows registered holders of the TYG’s common stock to make optional cash investments, in accordance with TYG’s Plan, on a monthly basis.

If a stockholder’s shares are registered directly with the Fund or with a brokerage firm that participates in the Fund’s Plan, all distributions are automatically reinvested for stockholders by the Agent in additional shares of common stock of the Fund (unless a stockholder is ineligible or elects otherwise). Stockholders holding shares that participate in the Plan in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. Stockholders who elect not to participate in the Plan will receive all distributions payable in cash paid by check mailed directly to the stockholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by Computershare, as dividend paying agent. Distributions subject to tax (if any) are taxable whether or not shares are reinvested.

Any single investment pursuant to the cash purchase option under TYG’s Plan must be in an amount of at least $100 and may not exceed $5,000 per month unless a request for waiver has been granted. A request for waiver should be directed to TYG at 1-866-362-9331 and TYG has the sole discretion to grant any requested waiver. Optional cash investments may be delivered to the Agent by personal check, by automatic or electronic bank account transfer or by online access at www.computershare.com. TYG reserves the right to reject any purchase order. Stockholders who hold shares in street or other nominee name who want to participate in optional cash investments should contact their broker, bank or other nominee and follow their instructions. There is no obligation to make an optional cash investment at any time, and the amount of such investments may vary from time to time. Optional cash investments must be received by the Agent no later than two business days prior to the monthly investment date (the “payment date”) for purchase of common shares on the next succeeding purchase date under TYG’s Plan. Scheduled optional cash purchases may be cancelled or refunded upon a participant’s written request received by the Agent at least two business days prior to the purchase date. Participants will not be able to instruct the Agent to purchase common shares at a specific time or at a specific price.

If on the distribution payment date or, for TYG, the purchase date for optional cash investments, the net asset value per share of the common stock is equal to or less than the market price per share of common stock plus estimated brokerage commissions, the Fund will issue additional shares of common stock to participants. The number of shares will be determined by the greater of the net asset value per share or 95 percent of the market price. Otherwise, shares generally will be purchased on the open market by the Agent as soon as possible following the payment date or purchase date, but in no event later than 30 days after such date except as necessary to comply with applicable law. There are no brokerage charges with respect to shares issued directly by the Fund as a result of distributions payable either in shares or in cash or, for TYG, as a result of optional cash investments. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Agent’s open-market purchases in connection with the reinvestment of distributions or optional cash investments. If a participant elects to have the Agent sell part or all of his or her common stock and remit the proceeds, such participant will be charged a transaction fee of $15.00 plus his or her pro rata share of brokerage commissions on the shares sold.

Participation is completely voluntary. Stockholders may elect not to participate in the Plan, and participation may be terminated or resumed at any time without penalty, by giving notice in writing, by telephone or Internet to Computershare, the Plan Agent, at the address set forth below. Such termination will be effective with respect to a particular distribution if notice is received prior to such record date.

Additional information about the Plan may be obtained by writing to Computershare Trust Company, N.A, P.O. Box 30170, College Station, TX 77842-3170. You may also contact Computershare by phone at (800) 426-5523 or visit their Web site at www.computershare.com.
