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 distribution policy (the “Policy”) with the purpose of distributing over the course of each year, through periodic distributions as nearly equal as practicable and any required special distributions, an amount closely approximating the total taxable income of TTP and TPZ during such year and, if so determined by the Board, all or a portion of the return of capital paid by portfolio companies to TTP and TPZ during such year. In accordance with its Policy, TTP distributes a fixed amount per common share, currently $0.16, each quarter to its common shareholders. TPZ distributes a fixed amount per common share, currently $0.05, 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 the remainder of 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.

2021 Semi-Annual Report to closed-end fund stockholders

Dear stockholder

The first half of the 2021 fiscal year started off strong. As many parts of the world are reopening, travel is picking up and with it energy demand. This translated into a significant recovery for energy infrastructure companies. The new administration and continued focus on ESG initiatives is driving positive fundamental momentum for renewable energy companies, despite a pullback in the first half of the fiscal year. Things have been returning to pre-COVID normal for schools with most expecting in-person learning in the fall and senior living facilities appear to be rebounding from the low of the pandemic. We think there will be compelling opportunities across all of these essential assets for investors as the year unfolds.

Energy and power infrastructure

The broader energy sector, as represented by the S&P Energy Select Sector^®Index, finished the semiannual period ending May 31, 2021 in significant positive territory, returning 45.48%. Energy markets and commodity prices experienced a significant turnaround propelled by the vaccine-driven rally since last November. As positive cases decline and mobility increases, global oil demand could exceed pre-pandemic levels over the next 12 months, a far-fetched thought one year ago.

There continues to be encouraging news around mobility and the economic reopening. According to Morgan Stanley, the mobility data in Israel, which is leading the world in vaccinations on a percentage basis, suggests demand for gasoline and diesel was up to 107% of its 2019 level. In the U.S., total refined product demand surged higher than the corresponding week in 2019. While a slower recovery should be expected in jet fuel, more Americans are traveling, with American Airlines announcing that April ticket sales hit 90% of pre-pandemic levels.

The Organization of Petroleum Exporting Countries (OPEC) and their Non-OPEC partners (OPEC+) continued deep production cuts with a clear goal of balancing the global crude oil market. Overall adherence to the production cut agreement remained strong in the first half of 2021 leading to inventory draws. The global crude oil market remains in deficit, supported by the OPEC+ crude oil production cut agreement, and inventory draws are expected to continue throughout 2021 driven by increased demand as the world economy re-opens.

U.S. crude oil production stabilized to start 2021. Through the first five months of 2021, U.S. crude oil production averaged 10.9 million barrels per day (b/d). This was a welcome change from the volatile 2020, which witnessed U.S. crude oil production fall from a record 13.1 million b/d in March 2020 to 10.3 million b/d in September 2020¹. For the remainder of 2021, the Energy Information Administration (EIA) forecasts that U.S. crude oil production will average 11.1 million b/d².

The COVID-19 pandemic accelerated U.S. producer capital discipline as investors focused on higher free cash flow (FCF) generation and return of capital to shareholders. In 2021, private producers started to increase activity levels yet public exploration & production companies’ (E&Ps) capital discipline remains with a growing portion of FCF going to shareholders through fixed dividends, variable dividends, and share buybacks. This was highlighted by EOG’s $1 per share special dividend and Devon Energy’s higher-than-expected variable dividend. EOG and Devon Energy were the first of public exploration and production companies to use fixed plus variable distribution model.

The natural gas market, like the crude oil market, tightened during the first half of the 2021 fiscal year. A cold winter in Europe and Asia led to a surge in demand resulting in liquefied natural gas (LNG) exports from the U.S. rapidly increasing to offset the global demand. There were other signs of healthy and rebounding demand. According to the EIA, in May 2021, natural gas storage was below its five-year average while at the same time LNG exports were above 11 billion cubic feet per day (Bcf/d), near all-time highs. Production growth is expected to remain concentrated in the highest quality basins, the Marcellus and Haynesville, and in the Permian Basin driven by associated natural gas. On the infrastructure side, we expect further opportunities down the road, particularly for LNG incumbents. Longer term, we believe natural gas continues to be a predominant bridge fuel to reduce global CO₂emissions, along with renewables, as both take market share from coal.

Midstream energy performance was strong during the first half of the 2021 fiscal year with the Tortoise North American Pipeline Index^SMreturning 31.11% and the Tortoise MLP Index^®returning 42.46%. GDP estimates are rising, which should lead to increased energy demand and volumes flowing through pipelines. The market also became more focused on inflation, which historically is a positive for the energy sector and midstream stocks.

A couple of themes stood out for midstream businesses throughout the first half of the fiscal year. The 2021 first quarter earnings reporting period was one of the strongest for the group in recent memory. The two main drivers were the benefits from Texas winter storm Uri and increased revisions of 2021 estimated EBITDA driven by higher volume expectations due to the economy reopening. Midstream companies generated approximately $4 billion in additional EBITDA from the Texas winter storm Uri as they supplied the market with much needed natural gas and power as prices spiked, with Kinder Morgan and Energy Transfer being the biggest beneficiaries. 2021 EBITDA expectations were also revised higher based on increasing activity through the second half of the year. Volumes are being driven primarily by increased drilling activity from private producers with public E&Ps showing capital restraint. On the cost side, companies kept capital expenditures lower and are using the excess cash flow to reduce debt with stock buybacks as a secondary and growing consideration. Fifteen midstream companies now maintain active buyback programs and MPLX led purchases during the first quarter, buying back $155 million of stock.

As free cash flow generation continues to ramp, we expect earnings and distribution announcements will further highlight the stability of the midstream business model. Midstream FCF is expected to rise over the next several years to produce a FCF yield 10%-15% compared to S&P 500 FCF yield of 5%. Even with a tremendous run-up in valuations the midstream sector is still trading at a discount relative to its history. We believe the forthcoming FCF and share buybacks tailwinds can drive sustainable outperformance for the midstream sector.

2021 Semi-Annual Report | May 31, 2021

With inflation increasing during the first half of the fiscal year, many investors began to look towards midstream as an asset class with inflation protection. Pipelines typically have long-term contracts with inflation protection from regulated tariff escalators. For example, tariffs on regulated liquid pipelines often include an inflation escalator. This allows increases in-line with the change in the Producer Price Index (PPI), offering some protection from inflation. In May 2021, the PPI rose 0.8%, according to the U.S. Bureau of Labor Statistics. Even if May PPI levels were held flat through year end, the 2021 PPI would increase by 6.5%, which with the 0.78% added would amount to an annual tariff increase of over 7%.

The first half of the fiscal year also saw a presidential transition which added uncertainty to the regulatory environment. In terms of key regulatory announcements, the Biden administration made several announcements at the beginning of his presidency which resulted in more “bark than bite”. Those announcements included rejoining the Paris Climate Accord, issuing a temporary pause on leasing on federal lands and revoking the permit of the Keystone XL Pipeline.

However, it is what the administration hasn’t done in its first months into the presidency which leads to a more constructive political and regulatory environment moving forward. The Army Corps of Engineers, an arm of the executive branch, deferred to the district court judge in regard to shutting down the Dakota Access Pipeline. Ultimately, the judge allowed the pipeline to continue to operate while its environmental impact statement is completed. Further, the Biden administration continues to allow drilling on federal lands, a much-discussed issue preceding the election. Finally, in response to the Colonial Pipeline cyberattack in May, U.S. Energy Secretary Jennifer Granholm talked about not relying too long on alternate truck or rail transport and that “Pipe is the best way to go.”³

The predominant theme around Biden’s energy plan is to address climate change and create substantial job opportunities for Americans. Climate change and related opportunities for the overall economy was one of the four pillars of the convention platform, integrated into an overall vision of revitalization of America. We are keeping a close eye on policy guidelines. The tight margin in both houses of congress likely forces legislation using the reconciliation process, which we expect tilts legislation towards tax credit policy rather than more restrictive, comprehensive climate policies.

Under President Biden’s infrastructure bill, the initial plan calls for 10 pilot projects targeting currently hard-to-abate sectors such as steel, cement, and chemicals. Traditional companies are calling for regulatory support including the expansion of Section 45Q tax credit. In fact, Exxon Mobil Corporation announced the largest proposed carbon capture sequestration project at approximately $100 billion. An expansion of these tax credits could make carbon capture adoption more widespread. Provided the necessary incentives, carbon capture, utilization and storage (CCUS) could grow 10x by 2030 and become a $1.0 trillion market by 2050. We believe the administration is taking a holistic view of this energy transition with the understanding that fossil fuels remain critical to the economy for decades.

The change in sentiment continued, with energy companies shifting from resisting energy transition to participating in the energy transition to start 2021. Some European oil majors openly discussed a shifting view and path forward around renewable energy. Engine No. 1, a small hedge fund, instigated an activist campaign on how ExxonMobil was approaching energy transition and ended up with three of its board of directors nominees elected to Exxon’s board. Some midstream companies formed sustainable development groups, and formal carbon reduction targets were established. This process should enhance environmental transparency by quantifying estimated greenhouse gas emissions from wellhead to cargo delivery point.

Carbon capture and hydrogen remain among the most discussed energy technologies energy companies can utilize to partake in the energy transition. Carbon capture was in the news with Exxon proposing a series of projects along the Gulf Coast which could total over $100 billion in investments. Carbon can either be captured directly from the atmosphere or in higher concentrations directly from point sources, such as industrial exhaust. We believe existing U.S. CO₂pipeline infrastructure is critical to accommodate carbon volumes, and more infrastructure will need to be built or repurposed to transport the captured carbon. Pipeline infrastructure could also be repurposed to transport hydrogen. Hydrogen transportation, including blending 5-10% of hydrogen into the methane stream presents opportunities for existing pipeline infrastructure or creates new large-scale infrastructure opportunities. As the world demands more energy and less carbon, we encourage midstream companies to view energy transition opportunistically.

Within the downstream portion of the energy value chain, optimism towards the refining sector has been increasing as the pace of domestic demand recovery has been leading to tighter supply/demand balances relative to the 2019 baseline considering capacity closures. Permanent refinery closures have helped and continue to help balance the market from a supply and demand perspective. From a U.S. refined product standpoint, gasoline and diesel are near pre-COVID levels while a slower recovery is expected in jet fuel. As U.S. energy demand recovers in 2021, U.S. refinery utilization and throughput should return to more normalized levels.

Natural gas liquids, unlike the refining sector proved resilient despite challenges faced during the COVID-19 pandemic. Strength in LPGs (liquid petroleum gases) has been notable, where demand is driven by global population growth and improvements in living standards in Asia, notably in China and India.

Sustainable infrastructure

Renewable energy

The first half of the fiscal period was turbulent for renewable energy due to a reflation rotation and concerns about inflationary impacts on renewable project returns along with more aggressive bidding for renewable project sites by oil and gas companies. We saw meaningful equity price corrections across many of the ‘champions’ of the broader space, following a banner year in 2020.

Tortoise	3

Many of the headwinds impacting the first fiscal quarter continued into the second fiscal quarter, particularly the reflation trade, which delivered stark underperformance of structural growth versus value cyclicals, and the continuing underperformance of pure-play renewables stocks. An additional headwind that grew in significance during the second quarter was strength in commodity and freight pricing which threatened to squeeze renewable equipment supplier margins and renewable developer returns. Many of the pricing framework agreements for renewable equipment had already been set, as well as some power purchase agreements for renewable developers. The ability to pass through higher raw material costs is likely to be challenging.

Ongoing strength in polysilicon, steel and copper prices added to the string of uncertainties surrounding the renewable equipment and renewable developers that investors contemplated during the first half of the year. Given the fact that in many regions renewable power purchase agreements are already attractively priced relative to prevailing spot and forward electricity prices, renewable developers should have the ability to enforce pricing power and to defend new project returns by stabilising and/or increasing power purchase agreement pricing for new renewables projects.

From a macro perspective, inflationary impulses may peak around the middle of this year. Moving into the second half of 2021 and beyond, a normalization of inflation should result in less individual factor leadership (such as cyclical and value which dominated the first half) and provide a more benign backdrop for stock picking. There are policy drivers due in the second half of this year which should re-focus attention on the energy transition: the European Commission is expected to release new emissions reduction targets for various industries in July; US infrastructure stimulus is on the agenda for H2 (and should include various tax credits and incentives for renewable technologies such as wind, solar and battery storage and incentives for electric vehicles as well as building efficiency); and the COP26 climate summit in November should encourage more ambitious decarbonization targets from governments and corporates.

Waste transition

During the first half of 2021, fuel credit prices improved. In fact, Renewable Identification Number (RIN) fuel credits under the Renewable Fuel Standards (RFS) are trading near all-time highs in the 13-year history of the federal program. The pricing strength is a result of increased demand with limited supply. The D3 RINs, which are created from the production of cellosic biofuels from methane, offer a good example of price behavior. In January 2020, D3 RIN credits were trading around $0.80, but reached $3.08 in June 2021, higher by nearly four times.

With regard to recycling efforts that support waste-to-value projects, the most notable legislative effort in recent years has been the movement to pass Extended Producer Responsibility (EPR) laws. These EPR laws require manufacturers to support the recycling of products and to incorporate more recycled content into products. EPR bills passed both the Maine and Oregon legislatures, awaiting only their respective governor’s signature to become law. Similar efforts in other states such as California and New York surfaced, and at the federal level with the U.S. House of Representatives.

Social impact

Education

Demand for high-yield K-12 charter public school and private school bonds for the first half of 2021 was exceptional with 83 offerings versus 70 during the same period in 2020. More significantly, the value of those bonds issued jumped more than 42% to $2,031,014,463.⁴Based on this, it is highly likely that high-yield K-12 charter school and private school bond issuance for 2021 will exceed the previous high for annual issuance of $4.19 billion.⁵

Another positive trend observed was a steady increase in schools reopening for in-person learning. To start the year, only 31.7% of U.S. K-12 students had the option of full-time, in-person learning with virtual-only instruction required for 53.4% of students. By the end of the school year, full-time, in-person learning was available to 69.7% of U.S. K-12 students with 2.1% restricted to virtual-only instruction.⁶Barring a significant resurgence in COVID-19 infections, we believe nearly all U.S. school districts will offer full-time, in-person instruction options for the Fall 2021 school year.

February 2021 saw the release of new research by the Thomas B. Fordham Institute that offers new evidence refuting one of the most significant claims made by opponents of charter public schools. That charter schools “take money away” from students in “public” schools has become one of the most prolific and effective arguments used both to prevent the growth of new charter schools and even to push for the elimination of existing, high-performing charter schools. In their report, “Victims or Robbers? Charter Schools and District Finances,” researchers at the Fordham Institute found: “In most states, an increase in the percentage of students attending independent charter schools was associated with an increase in host districts’ local revenue per pupil, and in some states, it was also associated with an increase in state and/or federal revenue per pupil.”⁷This while acknowledging the fallacy of the arguments since Charter Schools are by definition Public Schools.

Finally, new data released by the National Center on Education Statistics in June indicated that total public school enrollment in the US for 2020-2021 decreased by approximately 3%, or 1.5 million students, as compared to the 2019-2020 school year. Previously, U.S. Public School enrollment increased nearly every year since 2000, and in no year has it decreased by more than 1%.⁸While no definitive data is yet available, anecdotal reports suggest the pandemic generated significant increases in the number of parents homeschooling children or placing them into private schools. We expect to see the return of public school enrollment growth for the 2021-2022 school year in conjunction with the reopening of schools for full-time, in-person instruction. Given the widely reported frustration with many school districts and large urban school districts in particular, we believe charter schools are well positioned to benefit from that enrollment growth.

Senior Living

In the second quarter of 2021, the senior living sector happily established a “bottom” in occupancy deterioration since the pandemic began and began its rebound. As evidence of the rebound, NIC’s weekly executive survey of operators across the

(unaudited)

2021 Semi-Annual Report | May 31, 2021

nation through June 13, 2021 included the following highlights; (1) nine out of 10 organizations reported an increase in lead volume since the beginning of the year, (2) almost two-thirds of assisted living respondents reported the pace of move-ins has accelerated in the past 30 days and (3) 71% of assisted living organizations reported upward changes in occupancy⁹. While there’s clearly ground to cover, it’s revitalizing to see the sector making strides to get back to pre-pandemic levels.

Just as operations picked up, assisted living construction starts slowed. Nationally, the percentage of units under construction as a percentage of inventory sits at 5.4% at the end of the first quarter 2021. In December 2019, pre-COVID, that figure was 7.3%, down from an all-time high of 10% in late 2017⁹. Clearly this trend suggests less supply pressure on occupancy in the months ahead. Additionally, many developer partners view this as the time to capitalize on the “first mover’s advantage” given more than 70% of last year’s projects were put on hold, driving a flurry of capital markets activity to start the year¹⁰.

In June 2021, the University of Chicago and NIC released a study which examined COVID-19’s impact on senior housing in 2020. Two main takeaways from the study were; (1) lower acuity settings saw dramatically lower rates of COVID-related deaths and (2) continuing care retirement communities (CCRC’s) had half the COVID mortality rates by comparison to non-CCRC’s. Statistically, 67% of independent living, 64% of assisted living and 61% of memory care saw no COVID-19 related deaths which is staggering given the doomsday headlines of 2020⁹.

Statistically, through the first quarter of 2021, nationwide occupancy for independent living and assisted living decreased to 81.8% and 75.5%, respectively. Occupancy decreased for independent and assisted living, 7.9% and 9.7%, respectively since the pandemic began⁹. It’s worth noting, primary markets witnessed a higher rate of decline than the secondary markets we typically invest in. Moreover, many senior living communities experienced a particularly tough 2020 holiday season before vaccinations were made available to our communities. As mentioned, many of our senior living operators feel like the 2020 holidays were the lowest point operationally and the industry is poised to recover.

Clearly it will not happen overnight, but we are optimistic the senior living community is ready to rebound to pre-COVID occupancy levels in short order.

Concluding thoughts

As people continue to receive vaccinations and the economy opens due to increased mobility, we see positive momentum across the essential assets in which we invest. Increased travel is positive for energy demand that impacts the entire energy value chain. In the social impact segment, charter schools have been gearing up for in-person classes in the fall and senior living facilities have continued to normalize operations. Renewable energy stocks slowed down during the first half of the fiscal year with a few headwinds, but mostly pulling back from an extremely strong 2020. We are optimistic about essential assets and our funds for the remainder of 2021 and beyond.

2021 Semi-Annual Report | May 31, 2021

Fund structure and distribution policy

The fund is structured as a corporation and is subject to federal and state income tax on its taxable income. The fund has adopted a distribution policy in which the Board of Directors considers many factors in determining distributions to stockholders, including NAV performance and distributable cash flow (DCF). The fund’s Board of Directors reviews the distribution rate at least quarterly, and may adjust the quarterly distribution throughout the year. Although the level of distributions is independent of the funds’ performance in the short term, the fund expects such distributions to correlate with its performance over time.

Distributable cash flow and distributions

DCF is distributions received from investments less expenses. The total distributions received from investments include the amount received as cash distributions from investments, paid-in-kind distributions, and dividend and interest payments. Income also includes the premiums received from sales of covered call options, net of amounts paid to buy back out-of-the-money options. The total expenses include current or anticipated operating expenses, leverage costs and current income taxes. Current income taxes include taxes paid on net investment income, in addition to foreign taxes, if any. Taxes incurred from realized gains on the sale of investments, expected tax benefits and deferred taxes are not included in DCF.

For the six months ended May 31, 2021, income from investments decreased approximately 7.0% as compared to the six months ended November 30, 2020, primarily due to lower distributions from investments within the fund’s portfolio. Operating expenses, consisting primarily of fund advisory fees, increased approximately 17.0% during the period due primarily to higher asset-based fees. Overall leverage costs decreased approximately 2.5% as compared to the six months ended November 30, 2020 due to lower interest rates during the period. As a result of the changes in income and expenses, DCF decreased approximately 12.1% as compared to the six months ended November 30, 2020. The fund paid cumulative distributions of $0.655 per share during the six months ended May 31, 2021, an increase of approximately 9.2% from the distributions paid during the six months ended November 30, 2020. The fund has paid cumulative distributions to stockholders of $145.65 per share since its inception in February 2004.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between distributions received from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: the Statement of Operations, in conformity with U.S. generally accepted accounting principles (GAAP), recognizes distribution income from MLPs and other investments on their ex-dates, whereas the DCF calculation may reflect distribution income on their pay dates; GAAP recognizes that a significant portion of the cash distributions received from MLPs and other investments are characterized as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital (net of any distributions deemed to be return of principal); and distributions received from investments in the DCF calculation include the value of dividends paid-in-kind (additional stock or MLP units), whereas such amounts may not be included as income for GAAP purposes and includes distributions related to direct investments when the purchase price is reduced in lieu of receiving cash distributions. Net premiums on options written (premiums received less amounts paid to buy back out-of-the-money options) with expiration dates during the fiscal quarter are included in the DCF calculation, whereas GAAP recognizes the net effect of options written as realized and unrealized gains (losses). Income for DCF purposes is reduced by amortizing the cost of certain investments that may not have a residual value after a known time period and by distributions received from investments deemed to be return of principal. The treatment of expenses in the DCF calculation also differs from what is reported in the Statement of Operations. In addition to the total operating expenses, including fee waiver, as disclosed in the Statement of Operations, the DCF calculation reflects interest expense, realized and unrealized gains (losses) on interest rate swap settlements, distributions to preferred stockholders, other recurring leverage expenses, as well as taxes paid on net investment income.

“Net Investment Income (Loss), before Income Taxes” on the Statement of Operations is adjusted as follows to reconcile to DCF for YTD and 2nd quarter 2021 (in thousands):

	YTD 2021			2nd Qtr 2021
Net Investment Loss,
before Income Taxes	$	(3,320	)	$	(1,892	)

Leverage

The fund’s leverage utilization decreased $2.3 million during the six months ended May 31, 2021, compared to the six months ended November 30, 2020, and represented 26.2% of total assets at May 31, 2021. At quarter-end, the fund was in compliance with applicable coverage ratios, 80.3% of the leverage cost was fixed, the weighted-average maturity was 2.1 years and the weighted-average annual rate on leverage was 3.48%. These rates will vary in the future as a result of changing floating rates, utilization of the fund’s credit facility and as leverage and swaps mature or are redeemed.

Income taxes

As of May 31, 2021, the fund’s deferred tax asset was zero. The fund had capital loss carryforwards of $446.8 million for federal income tax purposes, which can be used to offset future capital gains. To the extent that the fund has taxable income, it will owe federal and state income taxes. Tax payments can be funded from investment earnings, fund assets, or borrowings.

Fund structure and distribution policy

Distributable cash flow and distributions

DCF is distributions received from investments less expenses. The total distributions received from investments include the amount received as cash distributions from MLPs, paid-in-kind distributions, and dividend and interest payments. Income also includes the premiums received from sales of covered call options, net of amounts paid to buy back out-of-the-money options. The total expenses include current or anticipated operating expenses, leverage costs and current income taxes. Current income taxes include taxes paid on net investment income in addition to foreign taxes, if any. Taxes incurred from realized gains on the sale of investments, expected tax benefits and deferred taxes are not included in DCF.

For the six months ended May 31, 2021, income from investments decreased approximately 6.5% as compared to the six months ended November 30, 2020, primarily due to lower distributions from investments within the fund’s portfolio. Operating expenses, consisting primarily of fund advisory fees, increased approximately 7.9% during the period primarily due to higher asset-based fees. Leverage costs decreased approximately 29.1% as compared to the six months ended November 30, 2020 due to lower interest rates during the period. As a result of the changes in income and expenses, DCF decreased approximately 5.2% as compared to the six months ended November 30, 2020. The fund paid cumulative distributions of $0.690 per share during the six months ended May 31, 2021, an increase of approximately 11.3% from the distributions paid during the six months ended November 30, 2020. The fund has paid cumulative distributions to stockholders of $158.26 per share since its inception in July 2010.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between distributions received from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: the Statement of Operations, in conformity with U.S. generally accepted accounting principles (GAAP), recognizes distribution income from MLPs, common stock and other investments on their ex-dates, whereas the DCF calculation may reflect distribution income on their pay dates; GAAP recognizes that a significant portion of the cash distributions received from MLPs, common stock and other investments are characterized as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital; and distributions received from investments in the DCF calculation include the value of dividends paid-in-kind (additional stock or MLP units), whereas such amounts may not be included as income for GAAP purposes, and includes distributions related to direct investments when the purchase price is reduced in lieu of receiving cash distributions. Net premiums on options written (premiums received less amounts paid to buy back out-of-the-money options) with expiration dates during the fiscal quarter are included in the DCF calculation, whereas GAAP recognizes the net effect of options written as realized and unrealized gains (losses). The treatment of expenses in the DCF calculation also differs from what is reported in the Statement of Operations. In addition to the total operating expenses, including fee waiver, as disclosed in the Statement of Operations, the DCF calculation reflects interest expense, distributions to preferred stockholders, other recurring leverage expenses, as well as taxes paid on net investment income.

Leverage

The fund’s leverage utilization increased approximately $3.2 million during the six months ended May 31, 2021, compared to the six months ended November 30, 2020, and represented 25.0% of total assets at May 31, 2021. At quarter-end, the fund was in compliance with applicable coverage ratios, 27% of the leverage cost was fixed, the weighted-average maturity was 1.0 years and the weighted-average annual rate on leverage was 2.38%. 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 quarter, $8.2 million of Senior Notes and $0.5 million of preferred stock were paid in full upon maturity.

Income taxes

As of May 31, 2021, the fund’s deferred tax asset was zero. The fund had capital loss carryforwards of $566.0 million for federal income tax purposes, which can be used to offset future capital gains. To the extent that the fund has taxable income, it will owe federal and state income taxes. Tax payments can be funded from investment earnings, fund assets, or borrowings.

2021 Semi-Annual Report | May 31, 2021

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 intends to distribute an amount closely approximating the total taxable income for the year and, if so determined by the Board, distribute all or a portion of the return of capital paid by portfolio companies during the year. The fund may designate a portion of its distributions as capital gains and may also distribute additional capital gains in the last calendar 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. Although the level of distributions is independent of the funds’ performance in the short term, the fund expects such distributions to correlate with its performance over time.

Distributable cash flow and distributions

Distributable cash flow (DCF) is income from investments less expenses. Income from investments includes the amount received as cash or paid-in-kind distributions from common stock, master limited partnerships (MLPs), affiliates of MLPs, and pipeline and other energy companies in which the fund invests, and dividend payments on short-term investments. Income also includes the premiums received from sales of covered call options, net of amounts paid to buy back out-of-the-money options. The total expenses include current or anticipated operating expenses and leverage costs.

For the six months ended May 31, 2021, income from investments decreased approximately 0.9% as compared to the six months ended November 30, 2020, primarily due to lower distributions from investments within the fund’s portfolio. Operating expenses, consisting primarily of fund advisory fees, increased approximately 4.1% during the period primarily due to higher asset-based fees. Leverage costs decreased approximately 9.9% as compared to the six months ended November 30, 2020 due to lower interest rates during the period. As a result of the changes in income and expenses, DCF increased approximately 0.5% as compared to six months ended November 30, 2020. The fund had net realized gains on investments of approximately $2.2 million during the six months ended May 31, 2021. The fund paid cumulative distributions of $0.320 per share during the six months ended May 31, 2021, no change from the distributions paid during the six months ended November 30, 2020. The fund has paid cumulative distributions to stockholders of $54.39 per share since its inception in October 2011.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between income from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: (1) the Statement of Operations, in conformity with U.S. generally accepted accounting principles (GAAP), recognizes distributions and dividend income from MLPs, common stock and other investments on their ex-dates, whereas the DCF calculation may reflect distributions and dividend income on their pay dates; (2) GAAP recognizes that a significant portion of the cash distributions received from MLPs, common stock and other investments are characterized as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital; (3) income from investments in the DCF calculation includes the value of dividends paid-in-kind (additional stock or units), whereas such amounts may not be included as income for GAAP purposes; and (4) net premiums on options written (premiums received less amounts paid to buy back out-of-the-money options) with expiration dates during the fiscal quarter are included in the DCF calculation, whereas GAAP recognizes the net effect of options written as realized and unrealized gains (losses).

“Net Investment Income (Loss)” on the Statement of Operations is adjusted as follows to reconcile to DCF for YTD and 2nd quarter 2021 (in thousands):

	YTD 2021			2nd Qtr 2021
Net Investment Loss	$	(367	)	$	(204	)
Adjustments to reconcile to DCF:
Distributions characterized as
return of capital (ROC)		1,829			907
Other		10			4
DCF	$	1,472		$	707

Leverage

The fund’s leverage utilization was substantially unchanged during the six months ended May 31, 2021, compared to the six months ended November 30, 2020, and represented 23.3% of total assets at May 31, 2021. At quarter-end, the fund was in compliance with applicable coverage ratios, 100% of the leverage cost was fixed, the weighted-average maturity was 2.0 years and the weighted-average annual rate on leverage was 4.94%. 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.

2021 Semi-Annual Report | May 31, 2021

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

There continues to be encouraging news around mobility and the economic reopening. In the U.S., total refined product demand surged higher than the corresponding week in 2019. While a slower recovery should be expected in jet fuel, more Americans are traveling, and American Airlines announced that April ticket sales hit 90% of pre-pandemic levels. The Organization of Petroleum Exporting Countries (OPEC) and their Non-OPEC partners (OPEC+) have continued deep production cuts with a clear goal of balancing the global crude oil market. Overall adherence to the production cut agreement has remained strong in the first half of 2021 leading to inventory draws. The global crude oil market remains in deficit, supported by the OPEC+ crude oil production cut agreement, and expected inventory draws are expected to continue throughout 2021 driven by increased demand as the world economy re-opens. The fund’s market-based and NAV-based returns for the fiscal period ending May 31, 2021 were 57.4% and 40.5%, respectively (including the reinvestment of distributions).

Energy Independence Fund, Inc. (NDP) (continued)

Fund structure and distribution policy

The fund has adopted a distribution policy which intends to distribute an amount closely approximating the total taxable income for the year and, if so determined by the Board, distribute all or a portion of the return of capital paid by portfolio companies during the year. The fund may designate a portion of its distributions as capital gains and may also distribute additional capital gains in the last calendar 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. Although the level of distributions is independent of the funds’ performance in the short term, the fund expects such distributions to correlate with its performance over time.

Distributable cash flow and distributions

Distributable cash flow (DCF) is income from investments less expenses. Income from investments includes the amount received as cash or paid-in-kind distributions from investments and dividend payments on short-term investments. Income also includes the premiums received from sales of covered call options, net of amounts paid to buy back out-of-the-money options. The total expenses include current or anticipated operating expenses and leverage costs.

For the six months ended May 31, 2021, income from investments decreased approximately 1.6% as compared to the six months ended November 30, 2020, primarily due to lower distributions from investments within the fund’s portfolio. Operating expenses, consisting primarily of fund advisory fees, increased approximately 19.7% during the period primarily due to higher asset-based fees. Total leverage costs increased approximately 24.1% as compared to the six months ended November 30, 2020 due to higher interest rates during the period. As a result of the changes in income and expenses, DCF decreased approximately 24.1% as compared to the six months ended November 30, 2020.

The fund announced the temporary suspension of distributions during the 2nd quarter of 2020 and did not pay any distributions during the period through 2nd quarter of 2021. The fund has paid cumulative distributions to stockholders of $96.90 per share since its inception in July 2012.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between income from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: (1) the Statement of Operations, in conformity with U.S. generally accepted accounting principles (GAAP), recognizes distributions and dividend income from MLPs, common stock and other investments on their ex-dates, whereas the DCF calculation may reflect distributions and dividend income on their pay dates; (2) GAAP recognizes that a significant portion of the cash distributions received from MLPs, common stock and other investments are characterized as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital; (3) income from investments in the DCF calculation includes the value of dividends paid-in-kind (additional stock or units), whereas such amounts may not be included as income for GAAP purposes; and (4) net premiums on options written (premiums received less amounts paid to buy back out-of-the-money options) with expiration dates during fiscal quarter are included in the DCF calculation, whereas GAAP recognizes the net effect of options written as realized and unrealized gains (losses).

“Net Investment Income (Loss)” on the Statement of Operations is adjusted as follows to reconcile to DCF for YTD and 2nd quarter 2021 (in thousands):

	YTD 2021			2nd Qtr 2021
Net Investment Income (loss)	$	(9	)	$	7
Adjustments to reconcile to DCF:
Distributions characterized as
return of capital		295			136
DCF	$	286		$	143

Leverage

The fund’s leverage utilization decreased $0.8 million during the six months ended May 31, 2021, as compared to the six months ended November 30, 2020. The fund utilizes all floating rate leverage that had an interest rate of 1.19% and represented 7.7% 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.

2021 Semi-Annual Report | May 31, 2021

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.

Distributable cash flow and distributions

Distributable cash flow (DCF) is income from investments less expenses. Income from investments includes the accrued interest from corporate bonds, cash distributions and paid-in-kind distributions from master limited partnerships (MLPs) and other equity investments and dividends earned from short-term investments. The total expenses include current or anticipated operating expenses and leverage costs.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between income from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: (1) U.S. generally accepted accounting principles (GAAP), recognizes distribution income from MLPs, common stock and other investments on their ex-dates, whereas the DCF calculation may reflect distribution income on their pay dates; (2) GAAP recognizes that a significant portion of the cash distributions received from MLPs, common stock and other investments are characterized as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital; (3) income from investments in the DCF calculation includes the value of dividends paid-in-kind (additional stock or units), whereas such amounts may not be included as income for GAAP purposes; and (4) amortization of premium or discount for all securities is calculated using the yield to worst methodology for GAAP purposes while yield to call is used in calculating amortization for long-dated hybrid securities in the DCF calculation. The treatment of expenses in the DCF calculation also differs from what is reported in the Statement of Operations. In addition to the total operating expenses, including fee waiver, as disclosed in the Statement of Operations, the DCF calculation reflects interest expense and realized and unrealized gains (losses) on interest rate swap settlements as leverage costs.

“Net Investment Income (Loss)” on the Statement of Operations is adjusted as follows to reconcile to DCF for YTD and 2nd quarter 2021 (in thousands):

	YTD 2021		2nd Qtr 2021
Net Investment Income	$	759	$	332
Adjustments to reconcile to DCF:
Distributions characterized as
return of capital		1,699		862
DCF	$	2,458	$	1,194

Leverage

The fund’s leverage utilization was substantially unchanged during the six months ended May 31, 2021, compared to the six months ended November 30, 2020, and represented 18.6% of total assets at May 31, 2021. During the period, the fund maintained compliance with its applicable coverage ratios. At year-end, including the impact of interest rate swaps, approximately 100% of the leverage cost was fixed, the weighted-average maturity was 2.7 years and the weighted-average annual rate on leverage was 3.33%. These rates will vary in the future as a result of changing floating rates and as swaps mature or are redeemed.

Essential Assets Income Term Fund (TEAF)

Fund description

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 strong positive NAV performance in the first fiscal half of 2021. Energy infrastructure companies performed extremely well during the period, driven by a solid fundamental outlook and strengthening commodity prices. Listed sustainable infrastructure companies performance softened a bit relative to most of 2020, but generated modest gains during the period. TEAF’s private energy and social infrastructure sleeves also showed solid returns during the quarter.

We continue to hold a constructive outlook for the underlying assets in the TEAF portfolio looking into the second half of 2021. Listed energy infrastructure companies are expected to benefit from recovering energy demand, as well as constructive commodity prices in the second half of 2021. We expect to see robust free cash flow generation from our portfolio of listed energy infrastructure companies that will be supportive of return of capital to investors over the coming months. Listed sustainable infrastructure companies continue to face headwinds in the form of increasing input costs that could impact margins and growth in the near-term, however we continue to hold a positive view as valuations have become increasingly more attractive as the sector has lagged broader equity markets in recent months. Additionally, the secular tailwinds of de-carbonization and renewable generation build out have continued to strengthen increasing our conviction of the sector in the long-term. The portfolio of operating solar assets continued to perform well and as expected during the quarter. One project, that is mechanically complete, has experienced a minor delay in the interconnection with the local utility delaying in-service of the asset by a few months. We now expect that project to be online in the fall of 2021 at which point all assets will be fully operational.

We continue to progress on transitioning the portfolio to the targeted allocation of 60% direct investments. As of May 31, 2021, TEAF’s total direct investment commitments were approximately $126 million or approximately 50% of the portfolio. As previously mentioned, we have completed the fund’s allocation to direct sustainable and energy infrastructure investments. We expect to reach the targeted allocation for direct investments in the second half of 2021.

Listed Energy Infrastructure

●	Listed energy infrastructure equities were the strongest driver of performance in the TEAF portfolio during the first half of 2021
●	Positive equity performance during the period was driven by a solid recovery in global energy demand resulting from the rollout of COVID-19 vaccines, increased mobility trends and strong commodity prices
●	Crude oil prices rebounded strongly in the period as OPEC remains accommodative of global energy markets while demand for end products recover
●	Global LNG prices strengthened notably during the period due to rebounding demand and low inventory levels in North America and Europe
●	Free cash flow generation in the sector is expected to accelerate due to lower capital expenditures and stable earnings providing valuation support

Listed Sustainable Infrastructure

●	The six-month period was dominated by significant mean reversion on names which had performed well in 2020. Pure renewables companies as well as renewable-driven utilities were severely hit at the beginning of calendar year 2021 as investors turned their attention to the effects of inflationary pressure on returns and steepening yield curves.
●	Equity market flows switched out of long-duration defensive business models into more cyclical sectors. Clean energy and utilities’ performance stood at the bottom-end of MSCI World’s sectors.
●	In such context, TEAF’s sustainable listed infrastructure sleeve performed relatively well due to good diversification of risk across sub-segments. Commodity strength supported waste-to-energy while cyclical infrastructure holdings benefited from the re-opening trade through exposure to airports and toll roads.
●	Yield curves started to flatten towards the end of the 6-month period, leading to some gradual recovery in some regulated utilities names in the portfolio. Further easing of long-term interest rates as well as the positive impact of rising power and carbon prices on clean power generators bodes well for listed sustainable infrastructure in the second half of the year.

Essential Assets Income Term Fund (TEAF) (continued)

Social Infrastructure

●	TEAF completed two direct investments in the Social Infrastructure portfolio during the period
●	In March 2021, TEAF completed a debt investment in Clearwater at Glendora. Clearwater at Glendora will use the proceeds to construct a new, 117-unit Assisted Living and Memory Care facility in Glendora, California to meet the underserved needs for senior care in the specific submarket near the Los Angeles metropolitan area. The Developer and Manager is an experienced regional player in the senior living space. When complete, Clearwater at Glendora will offer a mix of studio, 1-bedroom and 2-bedroom units with amenities that provide for a high-end, luxury feel with prices that are comparable to other facilities in the area.
●	In April 2021, TEAF closed a debt investment in Dynamic BC Holding, a bioenergy engineering, construction and development firm. The funding will partially finance a waste-to-energy anaerobic digester facility near Green Bay, Wisconsin that will source manure from local dairy farms, which will be converted into renewable natural gas. The project will generate environmentally-friendly renewable natural gas and provide a sustainable method of recycling manure into fertilizer, thus reducing surface and groundwater pollution coming from nitrates, phosphorous and sediment runoff in the area.

Private Energy Infrastructure

●	No deals were completed in the Private Energy Infrastructure portfolio during the period

Private Sustainable Infrastructure

●	TEAF did not invest in any additional private sustainable infrastructure projects during the 6 month period as the fund previously reached its targeted allocation.
●	Operating assets held at TEAF continue to operate as expected with stable cash flow generation profiles driven by long-term contracts with highly-rated counterparties
●	TEAF expects the last solar project under construction in the portfolio to come online in fall 2021

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.

Distributable cash flow and distributions

DCF is income from investments less expenses. Income from investments includes the accrued interest from bonds, the amount received as cash or paid-in-kind distributions from investments and dividend payments on short-term investments. Income also includes the premiums received from sales of covered call options, net of amounts paid to buy back out-of-the-money options. The total expenses include current or anticipated operating expenses and leverage costs.

For the six months ended May 31, 2021, income from investments increased approximately 0.8% as compared to the six months ended November 30, 2020, primarily due to greater distributions from investments within the fund’s portfolio. Operating expenses, consisting primarily of fund advisory fees, increased approximately 2.3% during the period primarily due to higher asset-based fees. Total leverage costs decreased approximately 1.9% as compared to the six months ended November 30, 2020, primarily due to lower interest rates. As a result of the changes in income and expenses, DCF increased approximately 0.4% as compared to the six months ended November 30, 2020. The fund had net realized gains on investments of approximately $8.6 million during the six months ended May 31, 2021.

The fund paid monthly distributions of $0.075 per share during 2nd quarter 2021, no change from the prior quarter and the distributions paid in the 2nd quarter 2020. The fund’s Board of Directors has declared monthly distributions of $0.075 per share to be paid during 3rd quarter 2021. The fund has paid cumulative distributions to stockholders of $2.3105 per share since its inception in March 2019.

“Net Investment Income (Loss)” on the Statement of Operations is adjusted as follows to reconcile to DCF for YTD and 2nd quarter 2021 (in thousands):

	YTD 2021			2nd Qtr 2021
Net Investment Income (Loss),
before income taxes	$	3,137		$	788
Adjustments to reconcile to DCF:
Distributions characterized as
return of capital		2,434			2,030
Net premiums on options written		1,844			946
Amortization on certain investments		(670	)		(315	)
DCF	$	6,745		$	3,449

Leverage

The fund’s leverage utilization decreased $12.4 million during the six months ended May 31, 2021, as compared to the six months ended November 30, 2020. The fund utilizes all floating rate leverage that had an interest rate of 0.89% and represented 11.7% of total assets at quarter-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.

Notes to Financial Statements (unaudited)

May 31, 2021

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”) (formerly Tortoise MLP Fund, Inc.), Tortoise Pipeline & Energy Fund, Inc. (“TTP”), Tortoise Energy Independence Fund, Inc. (“NDP”), Tortoise Power and Energy Infrastructure Fund, Inc. (“TPZ”), and Tortoise Essential Assets Income 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 follow accounting and reporting guidance applicable to investment companies under U.S. generally accepted accounting principles (“GAAP”).

A. Use of Estimates
The preparation of financial statements in conformity with 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.

2021 Semi-Annual Report | May 31, 2021

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.

The Funds may invest in early-stage companies via private investments in public equity (“PIPE”) which are issued by a company in the secondary market as a means of raising capital. In connection with PIPE investments, the Fund may enter into unfunded commitments. Funding of the commitments is subject to various contingencies and are recognized as a financial instrument when the contingencies have been met. Funds are obligated to fund these commitments when the contingencies are met and therefore, the Funds must have cash sufficient to cover its obligation. As of May 31, 2021, TYG, NTG, TTP, NDP, TPZ and TEAF had unfunded commitments of $4,640,713, $1,843,878, $373,209, $201,600, $585,345 and $639,939, respectively, which consist of Private Investment in Public Entity (PIPE) agreements with sponsors of Special Purpose Acquisition Companies (SPAC).

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, 2021. These assets and liabilities are measured on a recurring basis.

TYG, NTG, TTP, TPZ and TEAF own units of preferred stock of Altus Midstream Company (“ALTM Pfd”) that were issued in a private placement transaction that closed on June 12, 2019. The preferred stock carries a conversion option into common stock after the 7th anniversary of issuance (June 12, 2026) with a conversion rate determined as the quotient of Altus’ common unit price divided by a 6% discount to the prior 20-Day Volume Weighted Average Price (“VWAP”). Alternately, Altus can force conversion into common stock at a value determined by a minimum rate of return: before 5 years: greater of 1.3x Multiple on Invested Capital (“MOIC”) or 11.5% Internal Rate of Return (“IRR”), and after 5 years: greater of 1.3x MOIC or 13.75% IRR. A discounted cash flow model prepared by an independent third party is being used to determine fair value of the level 3 ALTM Pfd securities. 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 preferred stock of Enterprise Products Partners L.P. (“EPD Pfd”) that were issued in a transaction that closed on September 30, 2020. The preferred stock carries a conversion option into common stock after the 5th anniversary of the Closing Date (September 30, 2025) with a conversion rate determined as the quotient equal to 100% of the Stated Series A Liquidation Preference plus accrued and unpaid distributions up to the applicable conversion date, divided by a 7.50% discount to the prior 5-Day VWAP of EPD’s common unit price. The issuer has an option to force conversion before the 2nd anniversary at 110%, after the 2nd anniversary and prior to the 4th anniversary at 107%, thereafter, prior to the 5th anniversary at 103%, thereafter, prior to the 6th anniversary at 101% and any time on or after the 6th anniversary at par. A discounted cash flow model prepared by an independent third party is being used to determine fair value of the EPD 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 May 31, 2021, the investment in MPL was valued at the most recent transaction price as the company is still in development with no day to day operations.

TEAF owns a construction note in Saturn Solar Bermuda 1, Ltd (“Saturn”). Under the terms of the note, Saturn pays interest monthly at an annual rate of 9%. A discounted cash flows model is being utilized to determine fair value of the construction 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.

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, 2021:

Assets at Fair Value	TYG		NTG		TTP		NDP		TPZ		TEAF

2021 Semi-Annual Report | May 31, 2021

Notes to Financial Statements (unaudited) (continued)

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. 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.

Subsequent to November 30, 2020, the Funds reallocated the amount of return of capital recognized for the period from December 1, 2018 through November 30, 2020 based on the 2020 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	87%	87%	$	58,631
NTG	86%	86%	$	166,249
TTP	62%	63%	$	71,482
NDP	34%	35%	$	10,735
TPZ	76%	78%	$	93,453
TEAF	64%	64%	$	51,439

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.

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
Each of TYG and NTG, as corporations, are obligated to pay federal and state income tax on its taxable income. Currently, the federal income tax rate for corporations is 21%.

TTP, NDP, TPZ and TEAF each qualify as a regulated investment company (“RIC”) under the Internal Revenue Code (“IRC”). As a result, TTP, NDP, TPZ and TEAF 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 invest in master limited partnerships (“MLPs”), which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, each Fund reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Funds’ tax expense or benefit, if applicable, is included in the Statements of Operations based on the component of income or gains (losses) to which such expense or benefit relates. For TYG and NTG, deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset will not be realized.

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, 2021, 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 on the following dates remain open to examination by federal and state tax authorities:

TYG — November 30, 2017 through 2020
NTG — November 30, 2017 through 2020
TTP, NDP and TPZ — November 30, 2017 through 2020
TEAF — November 30, 2019 through 2020

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, TTP, NDP, TPZ and TEAF each intend to make cash distributions of its investment company taxable income and capital gains to common stockholders. In addition, on an annual basis, TTP, NDP, TPZ and TEAF 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.

For tax purposes, distributions to stockholders for the year ended November 30, 2020 were characterized as follows:

	TYG		NTG		TTP		NDP	TPZ		TEAF
	Common	Preferred	Common	Preferred	Common	Preferred	Common	Common		Common
Qualified dividend income	—	—	—	—	—	—	—		8%		19%
Ordinary dividend income	—	—	—	—	—	—	—		49%		39%
Return of capital	100%	100%	100%	100%	100%	100%	100%		43%		42%
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, 2020 through May 31, 2021 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 utilizes interest rate swap contracts in an attempt to manage interest rate risk. Cash settlements under the terms of the interest rate swap contracts and the termination of such contracts are recorded as realized gains or losses in the accompanying Statements of Operations.

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.

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.

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 ASU is effective as of March 12, 2020 and generally can be applied through December 31, 2022. Management is evaluating the underlying securities referencing LIBOR or another reference rate that is expected to be discontinued as a reference rate over the period of time the ASU is effective.

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.

As of the date these financial statements were issued, the outbreak of the novel coronavirus (“COVID-19”) in many countries continues to adversely impact global commercial activity, and has contributed to significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving, and as cases of the virus have continued to be identified in additional countries, many countries have reacted by instituting quarantines and restrictions on travel. Such measures, as well as the general uncertainty surrounding the dangers and impact of COVID-19, are creating significant disruption in supply chains and economic activity. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID- 19. Nevertheless, COVID-19 presents material uncertainty and risk with respect to our and our portfolio companies performance and financial results.

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. Accrued liabilities are expenses incurred in the normal course of each Fund’s operations. Waived fees are not subject to recapture by the Adviser. The annual fee rates paid to the Adviser as of May 31, 2021 are as follows:

TYG — 0.95% up to $2,500,000,000, 0.90% between $2,500,000,000 and $3,500,000,000, and 0.85% above $3,500,000,000.
NTG — 0.95%.
TTP — 1.10%.
NDP — 1.10%.
TPZ — 0.95%.
TEAF — 1.35%.

U.S. Bancorp Fund Services, LLC d/b/a U.S. Bank Global Fund Services serves as each Fund’s administrator. Each Fund pays the administrator a monthly fee computed at an annual rate of 0.04% of the first $1,000,000,000 of the Fund’s Managed Assets, 0.01% on the next $500,000,000 of Managed Assets and 0.005% on the balance of the Fund’s Managed Assets.

U.S. Bank, N.A. serves as the Funds’ custodian. Each Fund pays the custodian a monthly fee computed at an annual rate of 0.004% of the Fund’s U.S. Dollar-denominated assets and 0.015% of the Fund’s Canadian Dollar-denominated assets, plus portfolio transaction fees.

5. Income Taxes

TYG and NTG:

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. Components of TYG’s and NTG’s deferred tax assets and liabilities as of May 31, 2021 are as follows:

	TYG			NTG
Deferred tax assets:
Net operating loss carryforwards	$	4,859,395		$	5,013,288
Capital loss carryforwards		103,786,710			130,281,998
Less: Valuation Allowance		(43,190,528	)		(107,737,427	)
		65,455,577			27,557,859
Deferred tax liabilities:
Basis reduction of investments		60,720,338			20,936,345
Net unrealized gain on investment securities		4,735,239			6,621,514
		65,455,577			27,557,859
Total net deferred tax liability (asset)	$	—		$	—

At May 31, 2021, a valuation allowance on deferred tax assets was necessary because each of TYG and NTG believe that it is not more likely than not that there is an ability to realize its deferred tax assets through future taxable income. TYG and NTG have recorded valuation allowances of $43,190,528 and $107,737,427 respectively. Any adjustments to TYG’s or NTG’s estimates of future taxable income will be made in the period such determination is made.

Total income tax expense for each of TYG and NTG differs from the amount computed by applying the federal statutory income tax rate of 21% to net investment loss and net realized and unrealized gains (losses) on investments for the period ended May 31, 2021, as follows:

	TYG			NTG
Application of statutory income tax rate	$	27,232,607		$	15,209,560

Total income tax expense (benefit)	$	11,389,112		$	7,180,283

Total income taxes are being calculated by applying the federal rate plus a blended state income tax rate.

For the period ended May 31, 2021, the components of income tax expense for TYG and NTG include the following:

	TYG		NTG

As of November 30, 2020, TYG and NTG had capital loss carryforwards of approximately $626,000,000 and $573,000,000 respectively.
TYG carried back approximately $171,000,000 of capital losses to the prior three years. Capital losses not carried back can be carried forward for 5 years. If not utilized, TYG’s capital losses will expire in the year ending November 30, 2025 and NTG’s capital losses will expire in the years ending November 30, 2024 and 2025. For corporations, capital losses can only be used to offset capital gains and cannot be used to offset ordinary income.

Notes to Financial Statements (unaudited) (continued)

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, 2021, TEAF consolidated the balance of a deferred tax expense of $245,022 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 27.98%.

At May 31, 2021, a valuation allowance on deferred tax assets was not deemed necessary because TEAF believes it is more likely than not that its able to realize its deferred tax assets through future taxable income. 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, 2021, as follows:

Application of Statutory Income tax rate	$	131,435
State Income taxes, net of federal tax effect		43,687
Permanent differences		69,900
Total income tax expense	$	245,022

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 from underlying investments, wash sales, straddles, swaps, differences in the timing of recognition of gains or losses on investments and distributions in excess of current earnings. These reclassifications have no impact on net assets or results of operations. Permanent book and tax basis differences, if any, may result in reclassifications of undistributed (accumulated) net investment income (loss), undistributed (accumulated) net realized gain (loss) and additional paid-in capital.

As of November 30, 2020, the components of accumulated earnings (deficit) on a tax basis were as follows

	TTP				NDP			TPZ			TEAF
Unrealized appreciation (depreciation)	$	(40,475,971	)		$	(12,167,134	)	$	(17,907,931	)	$	6,430,703
Capital loss carryforwards		(96,906,032	)			(179,586,271	)		(17,039,588	)		(49,088,137	)
Undistributed ordinary income		—				—			—			—
Other temporary differences		(82,989	)	⁽¹⁾		—			(8,817	)		(1,340,491	)	⁽²⁾
Accumulated earnings (deficit)	$	(137,464,992	)		$	(191,753,405	)	$	(34,956,336	)	$	(43,997,925	)

(1)	Primarily related to losses deferred under straddle regulations per IRC Sec. 1092 and dividends payable.
(2)	Primarily related to expenses of TEAF’s taxable subsidiary and losses deferred under straddle regulations per IRC Sec. 1092.

As of November 30, 2020, TTP, NDP, TPZ and TEAF had short-term capital loss carryforwards of approximately $17,780,000, $72,050,000, $2,600,000 and $49,100,000 respectively, and TTP, NDP and TPZ had long-term capital loss carryforwards of approximately $79,120,000, $107,600,000, $14,600,000 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.

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, 2020. For the taxable year ended November 30, 2020, TTP, NDP, TPZ and TEAF do not plan to defer any losses.

As of May 31, 2021, 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			TTP			NDP			TPZ			TEAF
Tax cost of investments	$	262,445,492		$	161,208,367		$	81,795,500		$	45,790,007		$	113,865,552		$	242,246,764

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, 2021, 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, 2021 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, 2021. 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, 2021, 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, 2021 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 3,230,000 shares of MRP Stock outstanding at May 31, 2021. TYG’s MRP Stock has a liquidation value of $10.00 per share plus any accumulated but unpaid distributions, whether or not declared. Holders of the MRP D Stock and MRP E Stock are entitled to receive cash interest payments semi-annually at a fixed rate until maturity. The TYG MRP Stock is not listed on any exchange or automated quotation system.

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 invests 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.

Interest Rate Swap Contracts
TYG has entered 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 is exposed 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.

The average notional amount of all open swap agreements for TYG for the period from December 1, 2020 through May 31, 2021 was $10,000,000, respectively.

The following table presents TYG’s interest rate swap contract, which is subject to a netting agreement, on a gross and a net basis at May 31, 2021:

2021 Semi-Annual Report | May 31, 2021

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.
