           Letter to Shareholders

DEAR SHAREHOLDER:

Overall, U.S. equity investors endured increased volatility for the year ended May 31, 2016, as the year was marked by two significant drawdowns. The S&P 500 Index, a widely followed barometer of the U.S. equity market, returned 1.7% during the prior twelve months. During this period, the U.S. equity market experienced its first correction in four years in August, losing just over 10% of its value in a little more than a week. While those losses were almost entirely recovered by the end of the year, 2016 began on a sharply lower path before recovering yet again. Small-cap investors were less fortunate, with a (6.0)% return for the small cap Russell 2000^® Index for the fiscal year. Investors had to process the first rate increase from the U.S. Federal Reserve (+0.25%) in nearly six years, a continued slowing of growth in China and the implications for global economic growth and the impact of commodity prices falling to lows not seen since 2009. During the year, there was significant dispersion in performance across sectors, with utilities and telecommunication services returning 15% and 12%, respectively, while companies within the materials and energy sectors fell (5)% and (10)%, respectively. Meanwhile, international stocks fell during the prior year, returning (11.4)%, as measured by the MSCI All Country World Index ex USA (in U.S. Dollar terms). International investment returns in U.S. Dollar terms were hampered again by the strengthening in the U.S. Dollar that continued into early 2016.

The Barclays U.S. Aggregate Bond Index, a broad U.S. bond market benchmark, returned 3.0% for the fiscal year ended May 31, 2016. Interest rates and credit spreads gyrated during 2015 and early 2016, at times putting some pressure on bond prices. Investors’ appetite for risk declined sharply during the second half of 2015 and early 2016, before rebounding significantly as oil prices recovered, reflected in the (0.8)% decline in the Barclays U.S. Corporate High Yield Index.

Our foremost goal at AMG Funds is to provide investment solutions that help our shareholders successfully reach their long-term investment goals. By partnering with AMG’s affiliated investment boutiques, AMG Funds provides access to a distinctive array of actively-managed, return-oriented investment strategies. Additionally, we oversee and distribute a number of complementary open-architecture mutual funds subadvised by unaffiliated investment managers. We thank you for your continued confidence and investment in AMG Funds. You can rest assured that under all market conditions our team is focused on delivering excellent investment management services for your benefit.

Respectfully,

Jeffery Cerutti

President

About Your Fund’s Expenses

As a shareholder of a Fund, you may incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on $1,000 invested at the beginning of the period and held for the entire period as indicated below.

ACTUAL EXPENSES

The first line of the following table provides information about the actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed annual rate of return of 5% before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds by comparing this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

AMG Managers Cadence Capital Appreciation Fund

Portfolio Manager’s Comments (unaudited)

For the fiscal year ended May 31, 2016, the AMG Managers Cadence Capital Appreciation Fund (Institutional Class) (the “Fund”) returned (1.7)%, lagging its benchmark, the Russell 1000^® Growth Index, which returned 1.6%.   PERFORMANCE SUMMARY Investors experienced a volatile ride during the fiscal year ended May 31, 2016. While the S&P 500, the Russell 1000^® and the Russell 1000^® Growth Indices all ended the fiscal year at essentially the same price levels as they started, each index experienced drawdowns of 10% to nearly 14% on two occasions during the year. By the market’s close on May 31st, the S&P 500 had a total return of +1.7%, the Russell 1000^®, +0.8%; and the Russell 1000^® Growth, +1.6%, with dividends accounting for much of each index’s 12-month total return. From the perspective of investment style, the Russell 1000^® Growth returned +1.6% versus the Russell 1000^® Value’s (0.1)% total return. Large-cap stocks led mid- and small-cap stocks, as the Russell Midcap^® index declined (2.0)%, and the Russell 2000^® fell (6.0)%.   The Fund’s holdings in information technology, consumer staples and financials contributed positively both to absolute and relative performance, while consumer discretionary, health care and energy detracted. The Fund averaged 28.1% in information technology, essentially in line with technology’s 27.8% average weight in the Russell 1000^® Growth Index, but achieved average gains of 11.7% that exceeded the +2.4% return for the sector. Within the sector, software and services represented nearly 21% of the portfolio, and achieved average gains of 23%. The Fund was modestly underweight consumer staples, averaging 9.4% versus the sector’s 11.2% weighting in the index. The Fund had average total returns of 15.9% in consumer staples, outperforming the sector’s 11.8% return of the benchmark. The Fund’s positions in consumer discretionary, health care and energy detracted from performance, with stock selection accounting for most of the fiscal year’s overall shortfall versus the Russell 1000^® Growth Index. Consumer discretionary was the Fund’s second largest sector weighting at 19.7% versus the index’s 21.0%. However, the Fund’s holdings lagged the sector performance, accounting for -217 basis points of shortfall relative to the benchmark. Within health care, the Fund’s pharmaceuticals and biotechnology holdings averaged 10.2% of the portfolio — slightly under the index’s 11.0% weighting — but declined an average 23.1% versus (11.3)% for the index, detracting 150 basis points from relative performance.   THE YEAR IN REVIEW   Macroeconomic issues dominated the fiscal-year performance of stocks and, by extension, essentially all asset classes and markets. Throughout the year, debate centered on the health of China’s economy and its banking system. While it was widely recognized that China’s growth was decelerating, would the slowdown become something more pernicious — a hard landing —that might spread to its trading partners and global neighbors? The market behavior of oil prices and essentially all industrial commodities, the strengthening Dollar, widening credit spreads and similar market-based risk indicators signaled that it might. Central bankers responded with accommodative monetary policies, including negative interest rates, to preempt the threat of cascading deflation and its economic consequences. This spilled onto U.S. shores, as the U.S Federal Reserve (the “Fed”) maintained its zero-interest-rate policy throughout the summer of 2015 and into mid-December to sidestep unintended deflationary policy actions that might undermine budding global growth.   While no one can state with absolute certainty what triggered the abrupt reversal on February 12, 2016, stock prices across the globe changed course, along with crude oil prices, industrial commodities, credit spreads and other indicators of recovering global economic health. From its highs of around $60 per barrel at the June 1, 2015, start of the fiscal year, West Texas Intermediate crude oil collapsed by nearly 57% to $26 by mid-February, 2016. Since then, oil has rallied by over 90% to around $50 a barrel¹. While not to the same extent, many industrial commodities have also recovered since mid-February, suggesting that the risks of global recession have lessened considerably. Similarly, economically-sensitive value stocks began to outperform the growth stocks that had been leading the market.   OUTLOOK   Volatile markets with sector leadership that rotates almost monthly may be the most difficult for investment managers to navigate. We believe that the U.S. economy will continue to improve, absent an unexpected economic or geopolitical shock from China or the Euro Zone. Recent data suggest the Fed, as well as other central banks, are hesitant to raise interest rates any time soon, although this seems to change like the weather in New England. While we make no attempt to forecast the behavior of investors or policy makers, our investment approach seeks to identify companies with improving business fundamentals and attractive relative valuations, wherever in the market they may be found. Consistent implementation of this philosophy and approach is the key to our long-term investment success. Thank you for your continued trust.   This commentary reflects the viewpoints of the Cadence Capital Management, LLC. as of May 31, 2016 and is not intended as a forecast or guarantee of future results.   ¹Source: Dow Jones & Co

CUMULATIVE TOTAL RETURN PERFORMANCE

AMG Managers Cadence Capital Appreciation Fund’s cumulative total return is based on the daily change in net asset value (NAV), and assumes that all dividends and distributions were reinvested. This graph compares a hypothetical $10,000 investment made in AMG Managers Cadence Capital Appreciation Fund’s Institutional Class on May 31, 2006, compared to a $10,000 investment made in the Russell 1000^® Growth Index for the same time period. The graph and table do not reflect the deduction of taxes that a shareholder would pay on a Fund distribution or redemption of shares. The listed returns for the Fund are net of expenses and the returns for the index exclude expenses. Total returns would have been lower had certain expenses not been reduced.

The table below shows the average annual total returns for the AMG Managers Cadence Capital Appreciation Fund and the Russell 1000^® Growth Index for the same time periods ended May 31, 2016.

Average Annual Total Returns1	One Year			Five Years			Ten Years
AMG Managers Cadence Capital Appreciation Fund 2,3,4,5
Investor Class		(1.98	)%		8.52	%		4.60	%
Service Class		(1.97	)%		8.65	%		4.74	%
Institutional Class		(1.67	)%		8.93	%		5.01	%
Russell 1000® Growth Index 6		1.61	%		12.11	%		8.78	%

The performance data shown represents past performance. Past performance is not a guarantee of future results. Current performance may be lower or higher than the performance data quoted. The investment return and principal value of an investment in the Fund will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost.

Investors should carefully consider the Fund’s investment objectives, risks, charges, and expenses before investing. For performance information through the most recent month end, current net asset values per share for the Fund and other information, please call (800) 835-3879 or visit our website at www.amgfunds.com for a free prospectus. Read it carefully before investing or sending money.

¹  Total return equals income yield plus share price change and assumes reinvestment of all dividends and capital gain distributions. Returns are net of fees and may reflect offsets of Fund expenses as described in the prospectus. No adjustment has been made for taxes payable by shareholders on their reinvested dividends and capital gain distributions. Returns for periods greater than one year are annualized. The listed returns on the Fund are net of expenses and based on the published NAV as of May 31, 2016. All returns are in U.S. dollars ($).

²  From time to time, the Fund’s advisor has waived its fees and/or absorbed Fund expenses, which has resulted in higher returns.

³  The Fund invests in growth stocks, which may be more sensitive to market movements because their prices tend to reflect future investor expectations rather than just current profits. Growth stocks may underperform value stocks during given periods.

⁴  The Fund invests in large-capitalization companies that may underperform other stock funds (such as funds that focus on small- and medium-capitalization companies) when stocks of large-capitalization companies are out of favor.

⁵  The Fund is subject to special risk considerations similar to those associated with the direct ownership of real estate. Real estate valuations may be subject to factors such as changing general and local economic, financial, competitive, and environmental conditions.

⁶  The Russell 1000^® Growth Index is a market capitalization weighted index that measures the performance of those Russell 1000 companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, the Russell 1000^® Growth Index is unmanaged, is not available for investment and does not incur expenses.

AMG Managers Cadence Mid Cap Fund

Portfolio Manager’s Comments (unaudited)

For the fiscal year ended May 31, 2016, the AMG Managers Cadence Mid Cap Fund (Institutional Class) (the “Fund”) returned (6.3)%, lagging its benchmark, the Russell Midcap^® Growth Index, which returned (3.7)%.   PERFORMANCE SUMMARY   Investors experienced a volatile ride during the fiscal year ended May 31, 2016. While the large-cap dominated S&P 500, Russell 1000^® and the Russell 1000^® Growth Indices all ended the fiscal year at essentially the same price levels as they started, it was not the same experience for investors in mid- and small-cap stocks. The Russell Midcap^® Index returned (2.0)%, while the Russell Midcap^® Growth was off 3.7% over this period. To underscore the month-to-month volatility, the Russell Midcap^® Growth Index failed to achieve positive returns for more than two sequential months before reversing and erasing any gains. At one point in mid-February, the index was off nearly 20% from its June 1, 2015, level. From the perspective of investment style, growth and value mirrored investor sentiment and rotated leadership until mid-February, when stocks began their latest leg up.   The Fund’s holdings in financials and consumer staples contributed positively both to absolute and relative performance, while health care and consumer discretionary detracted. The Fund averaged 12.5% in financials, modestly above the sector’s 11.8% average weight in the Russell Midcap^® Growth Index, but achieved average gains of 11.4%, exceeding the 1.4% return for the sector. The combination of positive security selection and weighting decisions added 99 basis points of positive attribution. Within financials, the Fund’s real estate holdings drove performance, gaining 26.0% and contributing 86 of the sector’s 99 basis points of relative return. Consumer staples holdings were strong performers during the fiscal year, as investors sought the safety of this defensive growth sector. Our staples holdings constituted 13.2% of the fund compared with 8.1% of the index, an overweighting of 5.1%, the largest in the portfolio. Food, beverage and tobacco stocks — constituting 9.3% of the Fund — were the sector leaders, gaining an average of 11.9% and adding 57 basis points to relative performance.   Health care and consumer discretionary offset the positive attribution of financials and staples. Health care stocks averaged 13.8% of the Fund and declined an average 21.1% over the period, subtracting 226 basis points of relative return. Consumer discretionary represented 22.8% of the Fund — the largest absolute position, but an underweight of 1.8% compared with the benchmark. The Fund’s holdings declined 13.3%, underperforming the sector’s (6.7)% return and detracting 154 basis points from relative return.   THE YEAR IN REVIEW   Macroeconomic issues dominated the fiscal-year performance of stocks and, by extension, essentially all asset classes and markets. Throughout the year, debate centered on the health of China’s economy and its banking system. While it was widely recognized that China’s growth was decelerating, would the slowdown become something more pernicious — a hard landing —that might spread to its trading partners and global neighbors? The market behavior of oil prices and essentially all industrial commodities, the strengthening Dollar, widening credit spreads and similar market-based risk indicators signaled that it might. Central bankers responded with accommodative monetary policies, including negative interest rates, to preempt the threat of cascading deflation and its economic consequences. This spilled onto U.S. shores, as the U.S. Federal Reserve (the “Fed”) maintained its zero-interest-rate policy throughout the summer of 2015 and into mid-December to sidestep unintended deflationary policy actions that might undermine budding global growth.   While no one can state with absolute certainty what triggered the abrupt reversal on February 12, 2016, stock prices across the globe changed course, along with crude oil prices, industrial commodities, credit spreads and other indicators of recovering global economic health. From its highs of around $60 per barrel at the June 1, 2015, start of the fiscal year, West Texas Intermediate crude oil collapsed by nearly 57% to $26 by mid-February, 2016. Since then, oil has rallied by over 90% to around $50 a barrel¹. While not to the same extent, many industrial commodities have also recovered since mid-February, suggesting that the risks of global recession have lessened considerably. Similarly, economically-sensitive value stocks began to outperform the growth stocks that had been leading the market.   OUTLOOK   Volatile markets with sector leadership that rotates almost monthly may be the most difficult for investment managers to navigate. We believe that the U.S. economy will continue to improve, absent an unexpected economic or geopolitical shock from China or the Euro Zone. Recent data suggest the Fed, as well as other central banks, are hesitant to raise interest rates any time soon, although this seems to change like the weather in New England. While we make no attempt to forecast the behavior of investors or policy makers, our investment approach seeks to identify companies with improving business fundamentals and attractive relative valuations, wherever in the market they may be found. Consistent implementation of this philosophy and approach is the key to our long-term investment success.

CUMULATIVE TOTAL RETURN PERFORMANCE (continued)

AMG Managers Cadence Mid Cap Fund’s cumulative total return is based on the daily change in net asset value (NAV), and assumes that all dividends and distributions were reinvested. This graph compares a hypothetical $10,000 investment made in AMG Managers Cadence Mid Cap Fund’s Institutional Class on May 31, 2006, compared to a $10,000 investment made in the Russell Midcap^® Growth Index for the same time period. The graph and table do not reflect the deduction of taxes that a shareholder would pay on a Fund distribution or redemption of shares. The listed returns for the Fund are net of expenses and the returns for the index exclude expenses. Total returns would have been lower had certain expenses not been reduced.

The table below shows the average annual total returns for the AMG Managers Cadence Mid Cap Fund and the Russell Midcap^® Growth Index for the same time periods ended May 31, 2016.

	One	Five	Ten
Average Annual Total Returns 1	Year	Years	Years
AMG Managers Cadence Mid Cap Fund 2,3,4,5
Investor Class	(6.64)%	6.94%	5.13%
Service Class	(6.50)%	7.10%	5.29%

The performance data shown represents past performance. Past performance is not a guarantee of future results. Current performance may be lower or higher than the performance data quoted. The investment return and principal value of an investment in the Fund will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost.

¹    Total return equals income yield plus share price change and assumes reinvestment of all dividends and capital gain distributions. Returns are net of fees and may reflect offsets of Fund expenses as described in the prospectus. No adjustment has been made for taxes payable by shareholders on their reinvested dividends and capital gain distributions. Returns for periods greater than one year are annualized. The listed returns on the Fund are net of expenses and based on the published NAV as of May 31, 2016. All returns are in U.S. dollars ($).

²    From time to time, the Fund’s advisor has waived its fees and/or absorbed Fund expenses, which has resulted in higher returns.

³    The Fund invests in growth stocks, which may be more sensitive to market movements because their prices tend to reflect future investor expectations rather than just current profits. Growth stocks may underperform value stocks during given periods.

⁴    The Fund is subject to risks associated with investments in mid-capitalization companies such as erratic earnings patterns, competitive conditions, limited earnings history, and a reliance on one or a limited number of products.

⁵    The Fund is subject to special risk considerations similar to those associated with the direct ownership of real estate. Real estate valuations may be subject to factors such as changing general and local economic, financial, competitive, and environmental conditions.

⁶    The Russell Midcap^® Growth Index measures the performance of the Russell Midcap companies with higher price-to-book ratios and higher forecasted growth values. The stocks are also members of the Russell 1000^® Growth Index. Unlike the Fund, the Index is unmanaged, is not available for investment, and does not incur expenses.

AMG Managers Cadence Emerging Companies Fund

Portfolio Manager’s Comments (unaudited)

For the fiscal year ended May 31, 2016, the AMG Managers Cadence Emerging Companies Fund (Institutional Class) (the “Fund”) returned 3.2%, outperforming its benchmark, the Russell Microcap^® Growth Index, which returned (14.6)%.   PERFORMANCE SUMMARY Investors experienced a volatile ride during the fiscal year ended May 31, 2016. While the large-cap dominated S&P 500, Russell 1000^® and the Russell 1000^® Growth Indices all ended the fiscal year at essentially the same price levels as they started, it was not the same experience for investors in small and micro-cap growth stocks. The Russell 2000^® Index returned (6.0)%, the Russell 2000^® Growth was off 9.1% and the Russell Microcap^® Growth Index dropped (14.6)% over this period. Month-to-month volatility was heightened, with the Microcap Growth Index off 17.3% in 3Q15 and down 19.9% between December 2015 and February 2016. From the perspective of investment style, growth and value mirrored investor sentiment and rotated leadership until mid-February, when stocks began their latest leg up.   The Fund’s positioning in the health care and information technology sectors were the primary drivers of the Fund’s outperformance for the fiscal year. In addition, every sector except energy contributed to positive relative performance. Health care, the largest sector in the Russell Microcap^® Growth Index at 39.1%, contributed 10.5% of the Fund’s total outperformance. Two industry groups constitute the sector: pharmaceuticals and biotechnology, which represented 28.2% of the index, and equipment and services, with 11.0%. Biotechnology’s nearly 2.5 years of market leadership reversed during the fiscal year. While our holdings were not immune to the selloff in the pharmaceuticals and biotechnology group, the Fund’s holdings were down an average of 17.1% versus the group’s (30.2)% decline in the Index. The Fund was also underweight the group: 14% compared with 28%, which also contributed to outperformance. The Fund’s holdings and positioning in health care equipment and services also contributed to relative performance. The portfolio achieved average gains of 10.5% versus the (13.8)% loss in the index, and the portfolio was overweight the group by 4.7% on average during the period. Information technology also contributed to relative performance, with average gains of 12.1% compared with (5.34)% for the benchmark. The Fund’s holdings in software and services, semiconductors and semi cap equipment and tech hardware all made positive contributions to relative performance.   THE YEAR IN REVIEW Macroeconomic issues dominated the fiscal-year performance of stocks and, by extension, essentially all asset classes and markets. Throughout the year, debate centered on the health of China’s economy and its banking system.

The table below shows the average annual total returns for the AMG Managers Cadence Emerging Companies Fund and the Russell Microcap^® Growth Index and the Russell 2000^® Growth Index for the same time periods ended May 31, 2016.

The performance data shown represents past performance. Past performance is not a guarantee of future results. Current performance may be lower or higher than the performance data quoted. The investment return and principal value of an investment in the Fund will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost.

Investors should carefully consider the Fund’s investment objectives, risks, charges and expenses before investing. For performance information through the most recent month end, current net asset values per share for the Fund and other information, please call (800) 835-3879 or visit our website at www.amgfunds.com for a free prospectus.

¹    Total return equals income yield plus share price change and assumes reinvestment of all dividends and capital gain distributions. Returns are net of fees and may reflect offsets of Fund expenses as described in the prospectus. No adjustment has been made for taxes payable by shareholders on their reinvested dividends and capital gain distributions. Returns for periods greater than one year are annualized. The listed returns on the Fund are net of expenses and based on the published NAV as of May 31, 2016. All returns are in U.S. dollars ($).

² From time to time, the Fund’s advisor has waived its fees and/or absorbed Fund expenses, which has resulted in higher returns.

³ The Fund invests in growth stocks, which may be more sensitive to market movements because their prices tend to reflect future investor expectations rather than just current profits. Growth stocks may underperform value stocks during given periods.

⁴ The Fund is subject to risks associated with investments in small-capitalization companies such as erratic earnings patterns, competitive conditions, limited earnings history, and a reliance on one or a limited number of products.

⁵ The Fund is subject to special risk considerations similar to those associated with the direct ownership of real estate. Real estate valuations may be subject to factors such as changing general and local economic, financial, competitive, and environmental conditions.

⁶ The Fund is subject to the special risks associated with investments in micro-cap companies, such as relatively short earnings history, competitive conditions, less publicly available corporate information and reliance on a limited number of products.

⁷ The Russell Microcap^® Growth Index measures the performance of the micro-cap growth segment of the U.S. equity market. It includes those Russell Microcap Index companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, the Index is unmanaged, is not available for investment, and does not incur expenses.

⁸ The Russell 2000^® Growth Index measures the performance of the Russell 2000 companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, the Index is unmanaged, is not available for investment, and does not incur expenses.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

AMG Funds III (the “Trust”) is an open-end management investment company, organized as a Massachusetts business trust and registered under the Investment Company Act of 1940, as amended (the “1940 Act”). Currently, the Trust consists of a number of different funds, each having distinct investment management objectives, strategies, risks, and policies. Included in this report are: AMG Managers Cadence Capital Appreciation Fund (“Capital Appreciation”), AMG Managers Cadence Mid Cap Fund (“Mid Cap”) and AMG Managers Cadence Emerging Companies Fund (“Emerging Companies”), each a “Fund” and collectively the “Funds.”

Capital Appreciation and Mid Cap offer Investor Class shares, Service Class shares and Institutional Class shares. Emerging Companies offers Service Class shares and Institutional Class shares. Each class represents an interest in the same assets of the Fund. Although all share classes generally have identical voting rights, each share class votes separately when required by law. Different share classes may pay different distribution amounts to the extent the net asset value per share and/or the expenses of such share classes differ. Each share class has its own expense structure. Please refer to a current prospectus for additional information on each share class.

The Funds’ financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates and such differences could be material. The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements:

a. VALUATION OF INVESTMENTS

Equity securities traded on a national securities exchange or reported on the NASDAQ national market system (“NMS”) are valued at the last quoted sales price on the primary exchange or, if applicable, the NASDAQ official closing price or the official closing price of the relevant exchange or, lacking any sales, at the last quoted bid price or the mean between the last quoted bid and ask prices (the “exchange mean price”). Equity securities traded in the over-the-counter market (other than NMS securities) are valued at the exchange mean price. Foreign equity securities (securities principally traded in markets other than U.S. markets) are valued at the official closing price on the primary exchange or, for markets that either do not offer an official closing price or where the official closing price may not be representative of the overall market, the last quoted sale price.

Fixed income securities purchased with a remaining maturity of 60 days or less are valued at amortized cost, provided that the amortized cost value is approximately the same as the fair value of the security valued without the use of amortized cost. Investments in other open-end regulated investment companies are valued at their end of day net asset value per share.

The Funds’ portfolio investments are generally valued based on independent market quotations or prices or, if none, “evaluative” or other market based valuations provided by third-party pricing services approved by the Board of Trustees of the Trust (the “Board”). Under certain circumstances, the value of certain Fund portfolio investments (including derivatives) may be based on an evaluation of fair value, pursuant to procedures established by and under the general supervision of the Board. The Valuation Committee, which is comprised of the Independent Trustees of the Board, and the Pricing Committee, which is comprised of representatives from AMG Funds LLC (the “Investment Manager”) are the committees appointed by the Board to make fair value determinations. Each Fund may use the fair value of a portfolio investment to calculate its net asset value (“NAV”) in the event that the market quotation, price or market based valuation for the portfolio investment is not readily available or otherwise not determinable pursuant to the Board’s valuation procedures, if the Investment Manager or the Pricing Committee believes the quotation, price or market based valuation to be unreliable, or in certain other circumstances. When determining the fair value of an investment, the Pricing Committee and, if required under the Trust’s securities valuation procedures, the Valuation Committee, seeks to determine the price that the Fund might reasonably expect to receive from current sale of that portfolio investment in an arms-length transaction. Fair value determinations shall be based upon consideration of all available facts and information, including, but not limited to (i) attributes specific to the investment; (ii) fundamental and analytical data relating to the investment; and (iii) the value of other comparable securities or relevant financial instruments, including derivative securities, traded on other markets or among dealers.

The values assigned to fair value portfolio investments are based on available information and do not necessarily represent amounts that might ultimately be realized in the future, since such amounts depend on future developments inherent in long-term investments. Because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and the differences could be material. The Board will be presented with a quarterly report showing as of the most recent quarter end, all outstanding securities fair valued by the Fund, including a comparison with the prior quarter end and the percentage of the Fund that the security represents at each quarter end.

With respect to foreign equity securities and certain foreign fixed income securities, the Board has adopted a policy that securities held in a Fund that can be fair valued by the applicable fair value pricing service are fair valued on each business day provided that each individual price exceeds a pre-established confidence level.

31

Notes to Financial Statements (continued)

U.S. GAAP defines fair value as the price that a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP also establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Funds. Unobservable inputs reflect the Funds’ own assumptions about the assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation.

The three-tier hierarchy of inputs is summarized below:

Level 1 – inputs are quoted prices in active markets for identical investments (e.g., equity securities, open-end investment companies)

Level 2 – other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs) (e.g., debt securities, government securities, foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, fair valued securities with observable inputs)

Level 3 – inputs are significant unobservable inputs (including the Fund’s own assumptions used to determine the fair value of investments) (e.g., fair valued securities with unobservable inputs)

Changes in inputs or methodologies used for valuing investments may result in a transfer in or out of levels within the fair value hierarchy. The inputs or methodologies used for valuing investments may not necessarily be an indication of the risk associated with investing in those investments. Transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period.

b. SECURITY TRANSACTIONS

Security transactions are accounted for as of trade date. Realized gains and losses on securities sold are determined on the basis of identified cost.

c. INVESTMENT INCOME AND EXPENSES

Dividend income is recorded on the ex-dividend date. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned. Dividend and interest income on foreign securities is recorded gross of any withholding tax. Non-cash dividends included in dividend income, if any, are reported at the fair market value of the securities received. Distributions received in excess of income from return of capital including real estate investment trusts (REITs) are recorded as a reduction of the cost of the related investment and/or as a realized gain. If the Funds no longer own the

applicable securities, any distributions received in excess of income are recorded as an adjustment to realized gain. Other income and expenses are recorded on an accrual basis. Expenses that cannot be directly attributed to a Fund are apportioned among the Funds in the Trust and other trusts within the AMG Funds family of mutual funds (collectively the “AMG Funds family”) and other affiliated funds based upon their relative average net assets or number of shareholders. Investment income, realized and unrealized gains and losses, the common expenses of each Fund, and certain Fund level expense reductions, if any, are allocated on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of each Fund.

The following Funds had certain portfolio trades directed to various brokers, under a brokerage recapture program, which paid a portion of such Fund’s expenses. For the fiscal year ended May 31, 2016, the amount by which the Fund’s expenses were reduced and the impact on the expense ratios, if any, were as follows: Capital Appreciation, Mid Cap and Emerging Companies were $3,680, $497 and $61, respectively, which were less than 1% of average net assets.

The Funds have a “balance credit” arrangement with The Bank of New York Mellon (“BNYM”), the Funds’ custodian, whereby each Fund is credited with an interest factor equal to 0.75% below the effective 90-day T-Bill rate for account balances left uninvested overnight. If the T-Bill rate falls below 0.75%, no credits will be earned. These credits serve to reduce custodian expenses that would otherwise be charged to each Fund. For the fiscal year ended May 31, 2016, the Funds’ custodian expense was not reduced.

Overdraft fees are computed at 1% above the effective Federal Funds rate on the day of the overdraft. For the fiscal year ended May 31, 2016, overdraft fees for Capital Appreciation, Mid Cap and Emerging Companies equaled $190, $362 and $30, respectively.

d. DIVIDEND AND DISTRIBUTIONS

Fund distributions resulting from either net investment income or realized net capital gains, if any, will normally be declared and paid at least annually in December, as described in the Funds’ prospectus. Distributions to shareholders are recorded on the ex-dividend date. Distributions are determined in accordance with federal income tax regulations, which may differ from net investment income and net realized capital gains for financial statement purposes (U.S. GAAP). Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Permanent book and tax basis differences, if any, relating to shareholder distributions will result in reclassifications to paid-in capital. Temporary differences arise when certain items of income, expense and gain or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. The permanent differences are primarily due to net operating losses. The temporary differences are due to differing treatments for losses deferred due to excise tax regulations and wash sales.

32

Notes to Financial Statements (continued)

The tax character of distributions paid during the fiscal years ended May 31, 2016 and May 31, 2015 were as follows:

	Capital Appreciation				Mid Cap
Distributions paid from:	2016		2015		2016		2015
Ordinary income	$	735,315	$	895,408	$	114,082	$	12,618
Short-term capital gains		—		—		4,872,791		14,271,502
Long-term capital gains		—		—		9,883,605		23,913,479
Return of capital		—		—		—		—
Totals	$	735,315	$	895,408	$	14,870,478	$	38,197,599

As of May 31, 2016, the components of distributable earnings (excluding unrealized appreciation/depreciation) on a tax basis consisted of:

	Capital Appreciation			Mid Cap		Emerging Companies
Capital loss carryforward		$(56,959,547	)		—		$(19,011,334	)
Undistributed ordinary income		286,341			$1,006,762		—
Undistributed short-term capital gains		—			—		—
Undistributed long-term capital gains		—			1,026,688		—
Late year loss deferral		(447,297	)		—		(462,246	)

e. FEDERAL TAXES

Each Fund intends to comply with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, and to distribute substantially all of its taxable income and gains to its shareholders and to meet certain diversification and income requirements with respect to investment companies. Therefore, no provision for federal income or excise tax is included in the accompanying financial statements.

Additionally, based on each Fund’s understanding of the tax rules and rates related to income, gains and transactions for the foreign jurisdictions in which it invests, each Fund will provide for foreign taxes, and where appropriate, deferred foreign taxes.

Management has analyzed the Funds’ tax positions taken on federal income tax returns as of May 31, 2016 and for all open tax years (generally, the three prior taxable years), and has concluded that no provision for federal income tax is required in the Funds’ financial statements. Additionally, management is not aware of any tax position for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next twelve months.

Net capital losses incurred in taxable years beginning after the enactment of the Regulated Investment Company Modernization Act of 2010, may be carried forward for an unlimited time period. Such losses will be required to be utilized prior to any loss carryovers incurred in pre-enactment taxable years, which generally expire eight years following the close of the taxable year in which they were incurred. As a result of this ordering rule, pre-enactment capital loss carryovers may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward retain their tax character as either short-

term or long-term capital losses, unlike pre-enactment losses which are considered all short-term.

f. CAPITAL LOSS CARRYOVERS AND DEFERRALS

As of May 31, 2016, the following Funds had accumulated net realized capital loss carryovers from securities transactions for federal income tax purposes as shown in the following chart. These amounts may be used to offset future realized capital gains, if any, through the expiration dates listed or in the case of post-enactment losses, for an unlimited time period.

	Capital Loss
	Carryover Amounts
					Expires
Fund	Short-Term		Long-Term		May 31,
Capital Appreciation
(Pre-Enactment)	$	56,959,547		—		2018
Mid Cap
(Post-Enactment)		—		—		—
Emerging Companies
(Pre-Enactment)	$	19,011,334		—		2018

For the fiscal year ended May 31, 2016, the following Funds utilized capital loss carryovers in the amount of:

	Capital Loss Carryovers Utilized
	Short-Term		Long-Term
Capital Appreciation		$7,946,144		—
Mid Cap		—		—
Emerging Companies		3,460,711		—

As of May 31, 2016, Mid Cap had no accumulated net realized capital loss carryovers from securities transactions for federal income tax purposes. Should the Fund incur net capital losses for the fiscal year ended May 31, 2017, such amounts may be used to offset future capital gains, for an unlimited time period.

g. CAPITAL STOCK

The Trust’s Declaration of Trust authorizes for each Fund the issuance of an unlimited number of shares of beneficial interest, without par value. Each Fund records sales and repurchases of its capital stock on the trade date. The cost of securities contributed to the Funds in connection with the issuance of shares is based on the valuation of those securities in accordance with the Funds’ policy on investment valuation.

Transactions by these shareholders may have a material impact on their respective Funds.

h. REPURCHASE AGREEMENTS AND JOINT REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements for temporary cash management purposes provided that the value of the underlying collateral, including accrued interest, will equal or exceed the value of the repurchase agreement during the term of the agreement. The underlying collateral for all repurchase agreements is held in safekeeping by the Fund’s custodian or at the Federal Reserve Bank. If the seller defaults and the value of the collateral declines, or if bankruptcy proceedings commence with respect to the seller of the security, realization of the collateral by the Funds may be delayed or limited.

Additionally, the Funds may enter into joint repurchase agreements for reinvestment of cash collateral on securities lending transactions under the securities lending program offered by BNYM (the “Program”), provided that the value of the underlying collateral, including accrued interest, will equal or exceed the value of the joint repurchase agreement during the term of the agreement. The Funds participate on a pro rata basis with other clients of BNYM in its share of the underlying collateral under such joint repurchase agreements and in its share of proceeds from any repurchase or other disposition of the underlying collateral. The underlying collateral for joint repurchase agreements is held in safekeeping by the Fund’s custodian or at the Federal Reserve Bank. If the seller defaults and the value of the collateral declines, or if bankruptcy proceedings commence with respect to the seller of the security, realization of the collateral by the Funds may be delayed or limited. Pursuant to the Program, the Funds are indemnified for such losses by BNYM.

At May 31, 2016, the market value of repurchase agreements or joint repurchase agreements outstanding for Capital Appreciation, Mid Cap and Emerging Companies were $1,492,668, $7,232,771 and $1,590,055, respectively.

2. AGREEMENTS AND TRANSACTIONS WITH AFFILIATES

For each of the Funds, the Trust has entered into an investment advisory agreement under which the Investment Manager, a subsidiary and the U.S. retail distribution arm of Affiliated Managers Group, Inc. (“AMG”), serves as investment manager to the Funds and is responsible for the Funds’ overall administration and operations. The Investment Manager selects one or more subadvisors for the Funds (subject to Board approval) and monitors each subadvisor’s investment performance, security holdings and investment strategies. Each Fund’s investment portfolio is managed by one or more portfolio managers who serve pursuant to a subadvisory agreement with the Investment Manager.

Investment management fees are paid directly by the Funds to the Investment Manager based on average daily net assets. For the fiscal year ended May 31, 2016, the Funds’ investment management fees were paid at the following annual rate of each Fund’s average daily net assets:

Capital Appreciation	0.45%
Mid Cap	0.45%
Emerging Companies	1.25%

The Investment Manager has contractually agreed, through at least October 1, 2016, to waive management fees (but not below zero) and/or reimburse Fund expenses in order to limit total annual Fund operating expenses after fee waiver and expense reimbursements (exclusive of taxes, interest (including interest incurred in connection with bank and custody overdrafts), shareholder servicing fees, distribution and service (12b-1) fees, brokerage commissions and other transaction costs, acquired fund fees and expenses and extraordinary expenses) of Capital Appreciation, Mid Cap and Emerging Companies to 0.72%, 0.72% and 1.42%, respectively, of each Fund’s average daily net assets subject to later reimbursement by the Funds in certain circumstances. The contractual expense limitation may only be terminated in the event the Investment Manager or a successor ceases to be the investment manager of the Fund or a successor fund, by mutual agreement between the Investment Manager and the AMG Funds’ Board of Trustees, or in the event of each Fund’s liquidation unless the Fund is reorganized or is a party to a merger in which the surviving entity is successor to the accounting and performance information of the Fund.

35

Notes to Financial Statements (continued)

Each Fund is obligated to repay the Investment Manager such amounts waived, paid, or reimbursed in future years provided that the repayment occurs within thirty-six (36) months after the waiver or reimbursement and that such repayment would not cause the Fund’s total annual operating expenses after fee waiver and respective expense reimbursements in any such future year to exceed that Fund’s contractual expense limitation amount.

For the fiscal year ended May 31, 2016, each Fund’s expiration of reimbursement are as follows:

	Capital				Emerging
Expiration Date	Appreciation		Mid Cap		Companies
Less than 1 year		$182,232		$191,090		$110,604
Within 2 years		138,134		152,818		108,830
Within 3 years		138,122		147,630		126,216
Total Amount Subject to Reimbursement		$458,488		$491,538		$345,650

The Funds are distributed by AMG Distributors, Inc. (the “Distributor”), a wholly-owned subsidiary of the Investment Manager. The Distributor serves as the distributor and underwriter for each Fund and is a registered broker-dealer and member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Shares of each Fund will be continuously offered and will be sold directly to prospective purchasers and through brokers, dealers or other financial intermediaries who have executed selling agreements with the Distributor. Subject to the compensation arrangement discussed below, generally the Distributor bears all or a portion of the expenses of providing services pursuant to the distribution agreement, including the payment of the expenses relating to the distribution of prospectuses for sales purposes and any advertising or sales literature.

The Trust has adopted a distribution and service plan (the “Plan”) with respect to the Investor Class shares, in accordance with the requirements of Rule 12b-1 under the 1940 Act and the requirements of the applicable rules of FINRA regarding asset-based sales charges. Pursuant to the Plan, each Fund may make payments to the Distributor for its expenditures in financing any activity primarily intended to result in the sale of each Fund’s Investor class shares and for maintenance and personal service provided to existing shareholders of that class. The Plan authorizes payments to the Distributor up to 0.25% annually of each Fund’s daily net assets attributable to the Investor Class shares.

For each of the Investor and Service Classes, the Board has approved reimbursement payments to the Investment Manager for shareholder servicing expenses (“shareholder servicing fees”) incurred. Shareholder servicing fees include payments to third parties such as a bank, broker-dealer, trust company or other financial intermediaries who provide shareholder recordkeeping, account servicing and other services. The Investor and Service Class shares may reimburse the Investment Manager for the actual amount incurred up to a maximum annual rate of each Class’s average daily net assets as shown in the table below.

The impact on the annualized expense ratios for the fiscal year ended May 31, 2016, were as follows:

	Maximum		Actual
Fund	Amount Allowed		Amount Incurred
Capital Appreciation
Investor Class		0.15%		0.05%
Service Class		0.25%		0.24%
Mid Cap
Investor Class		0.15%		0.14%
Service Class		0.25%		0.25%
Emerging Companies
Service Class		0.25%		0.23%

During the fiscal year ended May 31, 2016, the Investor Class of Capital Appreciation and Mid Cap received a one-time shareholder servicing credit of $49,390 and $3,727, respectively.

The Board provides supervision of the affairs of the Trust, other trusts within the AMG Funds family and other affiliated funds. The Trustees of the Trust who are not affiliated with an Investment Manager receive an annual retainer and per meeting fees for regular, special and telephonic meetings, and they are reimbursed for out-of-pocket expenses incurred while carrying out their duties as Board members. The Chairman of the Board and the Audit Committee Chair receive additional annual retainers. Certain Trustees and Officers of the Funds are Officers and/or Directors of the Investment Manager, AMG and/or the Distributor.

The Securities and Exchange Commission has granted an exemptive order that permits the Funds to lend and borrow money for certain temporary purposes directly to and from other eligible Funds in the AMG Funds family. Participation in this interfund lending program is voluntary for both the borrowing and lending funds, and an interfund loan is only made if it benefits each participating Fund. The Investment Manager administers the program according to procedures approved by the Board, and the Board monitors the operation of the program. An interfund loan must comply with certain conditions set out in the exemptive order, which are designed to assure fairness and protect all participating Funds. For the fiscal year ended May 31, 2016, the following Funds borrowed from other Funds in the AMG Funds family: Capital Appreciation borrowed varying amounts not exceeding $6,009,731 for 12 days paying interest of $1,062, Mid Cap borrowed varying amounts not exceeding $2,553,825 for 13 days paying interest of $475 and Emerging Companies borrowed $2,091,295 for four days paying interest of $208. The interest amount is included in the Statement of Operations as miscellaneous expense. The Funds did not lend to other Funds in the AMG Funds Family during the fiscal year ended May 31, 2016. At May 31, 2016, the Funds had no interfund loans outstanding.

Emerging Companies		57,634,665		57,193,802

The Funds had no purchases or sales of U.S. Government obligations during the fiscal year ended May 31, 2016.

4. PORTFOLIO SECURITIES LOANED

The Funds participate in the Program providing for the lending of securities to qualified brokers. Securities lending income includes earnings of such temporary cash investments, plus or minus any rebate to a borrower. These earnings (after any rebate) are then divided between BNYM, as a fee for its services under the Program, and the Funds, according to agreed-upon rates. Collateral on all securities loaned is accepted in cash and is maintained at a minimum level of 102% (105% in the case of certain foreign securities) of the market value, plus interest, if applicable, of investments on loan. It is the Funds’ policy to obtain additional collateral from or return excess collateral to the borrower by the end of the next business day, following the valuation date of the securities loaned. Therefore, the value of the collateral held may be temporarily less than the value of the securities on loan. Lending securities entails a risk of loss to the Funds if and to the extent that the market value of the securities loaned were to increase and the borrower did not increase the collateral accordingly, and the borrower fails to return the securities. Under the terms of the Program, the Funds are indemnified for such losses by BNYM. Cash collateral is held in a separate omnibus account managed by BNYM, who is authorized to exclusively enter into joint overnight government repurchase agreements. BNYM bears the risk of any deficiency in the amount of the cash collateral available for return to the borrower due to any loss on the collateral invested.

At May 31, 2016, the value of the securities loaned and cash collateral received, were as follows.

	Securities		Cash Collateral
Fund	Loaned		Received
Capital Appreciation	$	1,464,324		$1,492,668
Mid Cap		7,027,917		7,232,771
Emerging Companies		1,566,065		1,590,055

5. COMMITMENTS AND CONTINGENCIES

Under the Trust’s organizational documents, its trustees and officers are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Funds may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnifications. The maximum exposure to the Funds under these arrangements is unknown, as this would involve future claims that may be made against a Fund that have not yet occurred. However, based on experience, the Funds had no prior claims or losses and expect the risks of loss to be remote.

6. MASTER NETTING AGREEMENTS

The Funds may enter into master netting agreements with their counterparties for the securities lending program and repurchase agreements, which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate net exposure to the defaulting party or request additional collateral. For financial reporting purposes, the Funds do not offset financial assets and financial liabilities that are subject to master netting agreements in the Statement of Assets and Liabilities. For securities lending transactions, see Note 4.

Report of Independent Registered Public Accounting Firm

TO THE BOARD OF TRUSTEES OF AMG FUNDS III AND THE SHAREHOLDERS OF THE AMG MANAGERS CADENCE CAPITAL APPRECIATION FUND, AMG MANAGERS CADENCE MID CAP FUND AND AMG MANAGERS CADENCE EMERGING COMPANIES FUND:

In our opinion, the accompanying statements of assets and liabilities, including the schedules of portfolio investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of AMG Managers Cadence Capital Appreciation Fund, AMG Managers Cadence Mid Cap Fund and AMG Managers Cadence Emerging Companies Fund (the “Funds”) at May 31, 2016, and the results of their operations, the changes in their net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at May 31, 2016 by correspondence with the custodian and brokers, and the application of alternative auditing procedures where securities purchased had not been received, provide a reasonable basis for our opinion.

Item 2.  CODE OF ETHICS

Registrant has adopted a Code of Ethics. See attached Exhibit (a)(1).

Item 3.  AUDIT COMMITTEE FINANCIAL EXPERT

Registrant’s Board of Trustees has determined that independent Trustee Mr. Steven J. Paggioli qualifies as the Audit Committee Financial expert. Mr. Paggioli is “independent” as such term is defined in Form N-CSR.

Item 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES

(a)       Audit Fees

The aggregate fees billed by the Funds’ independent registered public accounting firm, PricewaterhouseCoopers LLP (“PwC”), to the Funds for the Funds’ two most recent fiscal years for professional services rendered for audits of annual financial statements, or services that are normally provided in connection with statutory and regulatory filings or engagements (“Audit Fees”) were as follows:

	Fiscal 2016	Fiscal 2015
AMG Managers Cadence Capital Appreciation Fund	$23,257	$22,770
AMG Managers Cadence Emerging Companies Fund	$23,347	$17,407
AMG Managers Cadence Mid-Cap Fund	$25,390	$24,265

(b)       Audit-Related Fees

There were no fees billed by PwC to the Funds in its two recent fiscal years for services rendered for assurance and related services that are reasonably related to the performance of the audit or review of the Fund’s financial statements, but are not reported as Audit Fees (“Audit-Related Fees”).

For the Funds’ two most recent fiscal years, there were no Audit-Related Fees billed by PwC for engagements related directly to the operations and financial reporting of one or more Funds by a Fund Service Provider. A Fund Service Provider is (a) any investment adviser to the Fund (not including any Subadvisor whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) or (b) any entity that provides ongoing services to the Fund and is controlling, controlled by or under common control with a Fund investment adviser described in (a).

(c)      Tax Fees

The aggregate fees billed by PwC to the Funds for the two most recent fiscal years for professional services rendered for tax compliance, tax advice, and tax planning (“Tax Fees”) were as follows:

	Fiscal 2016	Fiscal 2015
AMG Managers Cadence Capital Appreciation Fund	$7,225	$6,985
AMG Managers Cadence Emerging Companies Fund	$7,225	$6,985
AMG Managers Cadence Mid Cap Fund	$7, 225	$6,985

For the Funds’ two most recent fiscal years, Tax Fees billed by PwC for engagements by Fund Service Providers that related directly to the operations and financial reporting of the Funds were $0 for fiscal 2016 and $0 for fiscal 2015, respectively.

The services for which Tax Fees were charged comprise all services performed by professional staff in PwC’s tax division except those services related to the audit. Typically, this category would include fees for tax compliance, tax planning, and tax advice. Tax compliance, tax advice, and tax planning services include preparation of original and amended tax returns, claims for refund and tax payment-planning services, assistance with tax audits and appeals, tax advice related to mergers and acquisitions and requests for rulings or technical advice from taxing authorities.

(d)       All Other Fees

There were no other fees billed by PwC to the Funds for all other non-audit services (“Other Fees”) during the Funds’ two most recent fiscal years. During the same period, there were no Other Fees billed by PwC for engagements by Fund Service Providers that related directly to the operations and financial reporting of the Funds.

(e)(1) According to policies adopted by the Audit Committee, services provided by PwC to the Funds must be pre-approved by the Audit Committee. On an annual basis, the Audit Committee reviews and pre-approves various types of services that PwC may perform for the Funds without specific approval of each engagement, subject to specified budget limitations. As contemplated by the Sarbanes-Oxley Act of 2002 and related SEC rules, the Audit Committee also pre-approves non-audit services provided by PwC to any Fund Service Provider for any engagement that relates directly to the operations and financial reporting of the Funds. Any engagement that is not already pre-approved or that will exceed a pre-approved budget must be submitted to the Audit Committee for pre-approval. The Chairman of the Audit Committee is authorized on behalf of the Board of Trustees and the Audit Committee to approve the engagement of PwC to perform non-audit services subject to certain conditions, including notification to the Audit Committee of such pre-approval not later than the next meeting of the Audit Committee following the date of such pre-approval.

(e)(2) None.

(f) Not applicable.

(g) The aggregate fees billed by PwC in 2016 and 2015 for non-audit services rendered to the Funds and Fund Service Providers were $87,675 and $116,523, respectively. For the fiscal year ended May 31, 2016, this amount reflects the amounts disclosed above in Item 4(b),(c),(d), plus $66,000 in fees billed to the Fund Service Providers for non-audit services that did not relate directly to the operations and financial reporting of the Funds. For the fiscal year ended May 31, 2015, this amount reflects the amounts disclosed above in Item 4(b),(c),(d), plus $95,568 in fees billed to the Fund Service Providers for non-audit services that did not relate directly to the operations and financial reporting of the Funds.

(h) The Trust’s Audit Committee has considered whether the provision of non-audit services by registrant’s independent registered public accounting firm to the registrant’s investment advisor, and any entity controlling, controlled, or under common control with the investment advisor that provided ongoing services to the registrant that were not pre-approved by the Committee (because such services did not relate directly to the operations and financial reporting of the registrant) was compatible with maintaining the independence of the independent registered public accounting firm.

Item 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

Not applicable.

Item 6. SCHEDULE OF INVESTMENTS

The schedule of investments in unaffiliated issuers as of the close of the reporting period is included as part of the shareholder report contained in Item 1 hereof.

Item 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES

Not applicable.

Item 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES

Not applicable.

Item 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT COMPANIES AND AFFILIATED PURCHASERS

Not applicable.

Item 10.         SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

Not applicable.

Item 11.         CONTROLS AND PROCEDURES

(a)             The Registrant’s principal executive and principal financial officers have concluded, based on their evaluation of the registrant’s disclosure controls and procedures as of a date within 90 days of the filing of this report, that the Registrant’s disclosure controls and procedures are reasonably designed to ensure that information required to be disclosed by the Registrant on Form N-CSR is recorded, processed, summarized and reported within the required time periods and that information required to be disclosed by the registrant in the reports that it files or submits on Form N-CSR is accumulated and communicated to the Registrant’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

(b)             There were no changes in the Registrant’s internal control over financial reporting during the Registrant’s fourth fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to affect, the internal control over financial reporting.
