EATON VANCE APRIL 2018 TIMELY THINKING Why fight the Fed and the market? The case for loans as rates rise. SUMMARY The recent federal tax cuts and budget agreement represent major stimulative fiscal measures, coming at a time of strong growth. Payson F. Swaffield, CFA Chief Income Investment Officer Eaton Vance Management Investors continue to anticipate relatively tame inflation, despite the stimulus, and the stagflation potential of tariffs and a possible trade war. Floating-rate loans have benefited from the rising-rate market, and have the potential to gain further if the Fed and the market s fed funds forecasts pan out. Eaton Vance Management research has demonstrated that active floating-rate loan managers on average have outperformed the passive ETF approach, since the largest ETF began in 2011. At Eaton Vance, we value independent thinking. In our experience, clients benefit from a range of distinctive, strongly argued perspectives. That s why we encourage our independent investment teams and strategists to share their views on pressing issues even when they run counter to conventional wisdom or the opinions of other investment managers.

APRIL 2018 TIMELY THINKING THE CASE FOR LOANS AS RATES RISE 2 The first quarter might be summarized as the first time in quite a while that U.S. fiscal policy began to eclipse monetary policy as the main driver of the markets. The big question is whether the market is correctly assessing the landmark fiscal events of the quarter in terms of growth and inflationary impact. The fiscal measures include a $1.5 trillion federal tax-cut and a $1.3 trillion program that boosts federal spending by $300 billion over the first two years. Both are clearly stimulative, and potential drivers of growth and inflation. (The inflationary impact of the tax cuts has been the subject of debate. The supply-side perspective holds that the tax cuts will spark capital investment and productivity gains, increasing aggregate supply and dampening inflationary pressure. The contrary view is that stimulating an economy that is already near full capacity will fuel inflation.) We also saw President Trump introduce tariffs on aluminum and steel for selected countries. Trade wars have the potential to be contractionary in terms of economic impact, yet they can also be inflationary due to increased prices stemming from the tariffs. Of course, to the extent tariffs and trade wars fail to materialize, the case for growthdriven inflation gets stronger, as noted above. Real rates rise The bond market responded to this by pushing up the yield on the 10-year U.S. Treasury note by 33 basis points (bps) to 2.74% over the quarter (Exhibit A). This increase was roughly half what we had been anticipating for all of 2018. Besides the magnitude of the rise, what s surprising is that most of the increase reflected a rise in the real rate the difference between the nominal rate and inflation expectations. The 10-year break-even rate the level of inflation predicted by the pricing of U.S. TIPS barely budged, starting the quarter at 1.98% and ending at 2.06%. As a result, the 10-year real rate increased by 25 bps to 68 bps. Exhibit A 10-year U.S. Treasury yields rose, mostly due to the real rate component. 12/29/2017 3/31/2018 Change Nominal 2.41% 2.74% 0.33% Breakeven 1.98% 2.06% 0.08% Real 0.43% 0.68% 0.25% Sources: Bloomberg LLC and Eaton Vance, as of March 31, 2018. The entire yield curve told a similar story. Rates moved up across the curve in a modest flattening manner, with the difference between 10-year and 2-year Treasurys declining six bps to 47 bps. Investors weren t demanding a greater term premium at the end of the quarter than they were at the start. In other words, the bond market is expecting moderate growth with relatively tame inflation. The U.S. Federal Reserve and the market were also on the same page in terms of expected fed funds rate increases for the year, with a range of 2.00% to 2.25% expected in November 2018, based on the Fed's most recent dot plot and futures. This is unusual in recent years the market has been more skeptical of rate hikes than the Fed. The fiscal stimulus is coming at a time when global growth is still strong. Purchasing Managers' Indexes (PMI) remain above 50 in the U.S., eurozone and China, indicating economic expansion, though recent readings have ticked down in the eurozone and China. Exhibit B shows the growth in U.S. PMI and nonfarm payrolls for the past 15 months employment continues to increase, which so far has helped mitigate inflationary pressure.

If the market and the Fed are correct, an investment with a floating-rate feature has the potential to move up with short-term rates. If the Fed and the market have underestimated future inflation, as we believe to be the case, the floating-rate asset becomes even more valuable relative to fixed-income alternatives. Floating-rate loans (bank loans) may be the most widely recognized example of a floating-rate asset class. In the early stages of a rising-rate market, loans have already outperformed other fixed-income sectors. Exhibit C shows that loans are the only U.S. fixed-income sector with positive total return in the first quarter, based on the S&P/LSTA Leveraged Loan Index. The total return of 1.45% for loans was almost three points greater than the Bloomberg Barclays U.S. Aggregate Index. This is in contrast to last year, before the impact of Fed tightening activity was fully reflected, when loans were fourth among U.S. sectors. 62 61 60 59 58 57 56 55 54 53 52 Exhibit C Rising rates have pushed floating-rate bank loans to the lead of U.S. fixed-income sectors.

APRIL 2018 TIMELY THINKING THE CASE FOR LOANS AS RATES RISE 4 The active edge Importantly, investors considering an allocation to bank loans have the choice of doing so through actively managed open-end mutual funds or passively managed ETFs. Eaton Vance Management (EVM) is conducting research on the relative performance of active, open-end, fixed-income mutual funds compared with fixed-income index ETFs. Below we discuss the findings as they pertain to floatingrate loans. The research can provide an important context for investors making this choice. Exhibit D compares the rolling, three-year weighted average performance of open-end mutual funds in Morningstar s bank loan category with the largest bank loan ETF PowerShares Senior Loan Portfolio (BKLN), which represents 65% of overall loan ETF assets as of December 31, 2017 1. The comparison shows 46 rolling three-year periods starting with BKLN s inception in March 2011 through December 31, 2017. Active managers in the open-end funds outperformed BKLN in 43 of the 46 periods, by an average of 77 basis points per year. The EVM analysis further determined that the key component of the outperformance by actively managed loan funds was that they were benchmarked to a broad index, like the S&P/LSTA Leveraged Loan Index (the Broad Index), which had 962 issuers as of December 31, 2017, versus the relatively narrow index used by BKLN the S&P/LSTA Leveraged Loan 100 Index (the Narrow Index). And the Narrow Index, which contains the largest, most liquid 100 issuers in the loan market, consistently underperformed the Broad Index. Using the Narrow Index allowed BKLN to better track its benchmark, which means it can have lower volatility relative to the Narrow Index. However, the ETF lost the Exhibit D Active, open-end loan funds have outperformed the largest loan ETF 93% of the time. Exhibit E The largest loan ETF has underperformed its own benchmark, and the broad index.

Compares the average annual total returns of Morningstar open-end floating-rate loan universe, asset weighted, with the market-price return of shares of the PowerShares Senior Loan Portfolio (BKLN) ETF, for 46 monthly rolling 3-year periods that start with the March 2011 inception date of BKLN. The comparison uses returns on the lowest-expense-ratio share class, because that share class represents the majority of funds in the Morningstar category on an asset-weighted basis. Results may vary if other share classes with higher expense ratios are used. The ETF benchmark is the S&P/ LSTA Leveraged Loan 100 Index. Past performance is no guarantee of future results. See end of report for important information. 1 The analysis focused on BKLN as the dominant ETF in Morningstar s floating-rate loan category, rather than an average of the ETFs in that category to avoid the complexities of having different ETF benchmarks in the mix. Our results should be considered illustrative rather than a definitive comparison between loan open-end funds and ETFs.

The results are seen in Exhibit E, in which BKLN underperforms not just the broad S&P/LSTA Leveraged Loan Index, but also its own narrow benchmark (due to ETF expenses). In summary, since inception in 2011, BKLN has underperformed the average active loan manager, and failed to provide investors with the return potential offered by the broad asset class. The first quarter of 2018 saw fiscal stimulus on an already strong U.S. economy, rising rates across the yield curve and a modest change in inflation expectations. In our view those expectations may not have fully adjusted to the impact of these government actions. We believe this is a favorable environment for floating-rate assets, and for floating-rate loans in particular. Based on our research, active managers are better positioned than passive index managers to capture the full potential of the loan asset class for investors.

The secondary market for loans is a private, unregulated interdealer or inter-bank resale market. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede a Strategy s ability to buy or sell loans and may negatively impact the transaction price. It may take longer than seven days for transactions in loans to settle. It is unclear whether U.S. federal securities law protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. There can be no assurance that the liquidation of collateral securing a loan will satisfy the issuer s obligation in the event of nonpayment or that collateral can be readily liquidated. Investments in income securities may be affected by changes in the creditworthiness of the issuer and are subject to the risk of nonpayment of principal and interest. The value of income securities also may decline because of real or perceived concerns about the issuer's ability to make principal and interest payments. Investments rated below investment grade (typically referred to as "junk") are generally subject to greater price volatility and illiquidity than higher-rated investments. As interest rates rise, the value of certain income investments is likely to decline. Bank loans are subject to prepayment risk. Investments in foreign instruments or currencies can involve greater risk and volatility than U.S. investments because of adverse market, economic, political, regulatory, geopolitical or other conditions. Changes in the value of investments entered for hedging purposes may not match those of the position being hedged.

Unlike mutual funds, ETF shares trade on an exchange and are not individually redeemable from the fund. ETF shares are bought and sold at market-determined prices, which may vary throughout the trading day and may be higher or lower than net asset value (NAV). Lower minimums may apply to ETF trades than mutual fund purchases. Index ETFs typically have lower fees than actively managed mutual funds. ETFs utilizing in-kind redemptions may pay out lower capital gains distributions than similar mutual funds, reducing or deferring shareholder taxes. Eaton Vance does not provide tax or legal advice.
