December 31, 2016 William Blair Funds 5
 

U.S. Growth Market Review and Outlook

 

The strength of U.S. equity market returns in 2016 masked some sharp but short-lived downdrafts during the year. This dynamic resulted in a style environment where both more defensive and more cyclical areas of the market exhibited leadership at different times over the course of the year.

 

In the first six weeks of 2016, the market declined precipitously, driven by concern that the U.S. could be headed into a recession given weakness in the manufacturing segment of the economy, falling oil prices and persistent headwinds from global economic growth challenges. In this environment, equity investors gravitated toward the perceived safety of high dividend yielding stocks (a dominant factor in the performance of larger cap indices during this period) and away from more speculative areas of the market such as biotechnology (a dominant factor in the performance of smaller-cap indices during this period). The mid-February market reversal, wherein leadership shifted to more cyclical companies, was spurred by further easing of monetary policy by foreign central banks and improving macroeconomic data points globally. From that point forward, with only a brief pause following the results of the Brexit vote, generally positive U.S. economic data carried the market higher.

 

While fourth quarter returns were positive overall, the market softened somewhat in October, likely due to anxiety ahead of the U.S. presidential election as a solid third quarter earnings season indicated health among U.S. corporations. The surprise election of Donald Trump, whose proposed policies of lower taxes, increased fiscal spending and looser regulations are generally perceived as reflationary and pro-U.S. growth, provided a tailwind for more economically sensitive areas of the market. At the same time, U.S. economic data surpassed expectations. U.S. retail sales, housing starts, unemployment claims and wages were all among positively trending data points. Accordingly, 10 year Treasury yields moved higher as investor confidence rose. With a backdrop of continued low unemployment, rising wages and inflation moving higher, the Federal Reserve, in what had become a widely anticipated move, raised the federal funds rate by 25 basis points in December.

 

The new administration will take office with the U.S. economy moving into the latter half of its eighth year of expansion and the Fed poised to enact further interest rate increases. In terms of Republican initiatives, lower regulatory burden, higher fiscal spending and lower taxes are generally considered to be favorable for economic growth. However, it remains to be seen how quickly the new administration’s proposed policies can be implemented. While more restrictive monetary policy in the U.S. could hinder economic growth, the Fed has thus far exhibited a cautious pace of rate increases relative to a more normalized cycle and global central bank policies remain stimulative. Conversely, Trump’s proposed policies reinforce already rising inflation, increasing the potential that the Fed could move too slowly in raising rates. Additional risks in the U.S. include potential geo-political missteps and trade ramifications from protectionist policies.

 

Absolute valuations moved up with the market during the year. For instance, the S&P 500 Index forward price-to-earnings multiple expand from 16.2 to 17.5 times earnings over the course of 2016. However, as of December 31, 2016, growth style indices were trading at only modest premiums to historical median levels. At the same time, relative to value indices, growth style indices were trading considerably below historical median premiums. Given this backdrop, our general view is that opportunity remains for U.S. growth equities. Further, the prospect of lower corporate taxes, repatriation of overseas cash, reduced regulations, and fiscal stimulus could lead to positive earnings revisions. Conversely, potentially offsetting factors include continued strength in the U.S. dollar and wage inflation.

 

As always, we believe broad investor focus on near-term events creates opportunities for investors such as ourselves who analyze companies over a long-term time horizon in an effort to achieve excess returns. We remain focused on identifying companies with durable growth drivers, independent of policy outcomes, whose stocks present compelling risk/reward opportunities.

 

6 Annual Report December 31, 2016
 

U.S. Value Market Review and Outlook

 

The domestic equity markets delivered positive returns in 2016, though there was a significant dispersion of returns between growth and value style indices. Following several years of outperformance by growth stock indices, value indices considerably outperformed during the year.

 

Investors experienced one of the worst starts to a new year on record for the domestic equity markets as investor sentiment during the first six weeks of 2016 seemed hysterically negative and recessionary fears ran rampant. Concerns over slowing U.S. and global growth, further weakening of commodities, strengthening of the U.S. dollar, and renewed fears of a slowdown in China pushed most equity markets into correction territory. The mid-February reversal was spurred by better domestic economic data helping to alleviate investor angst of an impending recession. Also, dovish comments by the Federal Reserve helped spark a risk-on rally from mid-February through the end of the third quarter, with a slight pause following the results of the Brexit vote. This rally was led by smaller, lower quality, and less expensive stocks.

 

The hard-charging domestic equity markets paused briefly in October after posting robust returns since the mid-February lows as U.S. economic expansion continued to progress, albeit at a slow and uneven pace. Similar to what transpired at the end of the second quarter following the surprising Brexit vote, market volatility spiked in early November heading into the U.S. presidential election. Better economic data and generally perceived reflationary and pro-growth policy initiatives, including increased fiscal spending, tax reform, and deregulation, helped push volatility back to near-historic lows and ultimately ignited a post-election rally that propelled the equity markets higher in the fourth quarter. The post-election rally was primarily driven by smaller cap stocks that are expected to be beneficiaries of the pro-growth initiatives of the newly elected president. The decision by OPEC ministers to cut oil production more than anticipated helped drive oil prices higher, further fueling the strong market returns during the fourth quarter.

 

With all of the post-election rhetoric focused on the protectionist, pro-growth initiatives of President-elect Trump and an improved U.S. economic outlook, domestic interest rates rose along with the U.S. dollar. With the backdrop of continued low unemployment, rising wages, and inflation appearing to perk up, the Federal Reserve raised the federal funds rate by 25 basis points in December.

 

The improvement in domestic economic data continues to support the view that U.S. economic expansion is progressing. With Donald Trump taking office early in 2017, the prospects for lower taxes, repatriation of overseas cash, increased fiscal spending, deregulation, and higher interest rates could lead to positive earnings revisions, further extending this market cycle. Some potential offsetting factors to these policy initiatives include continued strength of the U.S. dollar and wage inflation. Investor optimism is high for Trump’s pro-growth initiatives; however, there is the possibility for investor disappointment resulting from the gap between what is anticipated and actual policy results, which could lead to increased market volatility. Volatility continues to be at or near historic lows and we continue to anticipate higher volatility going forward given the uncertainty created by Brexit, concerns over a slowdown in China, policies and priorities of the newly elected U.S. president, and geopolitical tensions. There is a strong correlation between volatility and the performance of high quality companies, and higher volatility should benefit our strategy given our higher quality bias within the Funds.

 

While the Federal Reserve was able to squeeze in only one interest rate increase late in the year, we continue to believe that the Fed will be prudent with future rate increases and that the trajectory of interest rates will be lower than they would during a more normalized cycle. The beneficiaries of the universally accommodative monetary policy and ample liquidity during the current bull market have been the more highly leveraged companies. However, if interest rates rise faster than expected and lending standards continue to tighten, companies with conservative balance sheets and sufficient cash cushions, or those generating ample free cash flow should fare better than companies reliant on the capital markets to grow. This could provide a tailwind for our strategy as these higher quality companies with better balance sheets and solid cash flows should outperform under this scenario.

 

While we are cognizant of these macroeconomic variables, we are persistently seeking to identify attractive risk reward opportunities based on individual company fundamentals. From our bottom up perspective, we remain constructive on corporate earnings, albeit against a backdrop of lower revenue growth and increasing margin pressure from higher wages. As always, our focus remains on identifying quality companies at discount prices and corporate transformation opportunities, and we continue to find good ideas across all sectors. Given our investment approach, we believe the Funds are well-suited to withstand a variety of market scenarios and add value over the long-term.

  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

David C. Fording

 

 

John F. Jostrand

The William Blair Growth Fund (Class N shares) posted a 0.98% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell 3000® Growth Index (the “Index”), increased 7.39%.

 

Underperformance for 2016 versus the Index was due to a combination of style and stock-specific factors. From a style perspective, there were headwinds early in the year when investor preference for high dividend-yielding stocks dominated the market. While the preference for dividend yield was most pronounced at the beginning of the year, relative performance of high dividend-yielding stocks did not subside for the remainder of 2016 and high dividend-yielding stocks materially outperformed low dividend-yielding stocks in 2016. More economically-sensitive areas of the market also outperformed for the year, particularly in the third quarter and following the U.S. presidential election. The Fund tends to be significantly underweight high dividend- yielding and more economically-sensitive companies, preferring sustainable growth companies with substantial reinvestment opportunities that enable superior, durable long-term growth. From a stock-specific perspective, the largest detractor from the Fund’s relative performance was healthcare technology solutions provider Cerner after the company reported financial results below consensus expectations late in the year amid lower IT spending by hospitals, the company’s primary customers. Grocery retailer Kroger was a top detractor from relative performance for the year. The company experienced deflationary pressures on items such as milk, eggs and meat which negatively affected company earnings for much of 2016. However, fears of further deflation eased following the U.S. presidential election, and the stock was able to recover. Other top detractors from the Fund’s relative performance were Red Hat (Information Technology), BorgWarner (Consumer Discretionary) and Mead Johnson Nutrition (Consumer Staples). Top contributors for the year were rail operator Union Pacific and semiconductor manufacturer Texas Instruments. Union Pacific outperformed the Index mostly in the second half of 2016 due to improving trends in its underlying business. The stock performed particularly well following the election as investors gravitated to companies that would benefit the most from an improvement in the U.S. economy. Other top contributors to relative performance were Akamai Technologies (Information Technology), Vantiv (Information Technology) and NeuStar (Information Technology).

  The Large Cap Growth Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   



James S. Golan

 


David P. Ricci

The William Blair Large Cap Growth Fund (Class N shares) posted a 1.97% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell 1000® Growth Index (the “Index”), increased 7.08%.

 

Underperformance for 2016 versus the Index was primarily due to style headwinds. Headwinds were most pronounced early in the year when investor preference for high dividend-yielding stocks dominated the market. While this preference was concentrated mainly in January and February, relative performance of high dividend-yielding stocks did not subside for the remainder of 2016 and high dividend-yielding stocks materially outperformed low dividend-yielding stocks in 2016. Cheaper and more cyclical areas of the market also outperformed for the year, particularly following the U.S. presidential election. The Fund tends to be significantly underweight high dividend-yielding, low valuation and low growth companies, preferring companies with substantial reinvestment opportunities that enable superior, durable long-term growth. From a stock-specific perspective, the largest detractor from the Fund’s relative performance was grocery retailer Kroger. The company experienced deflationary pressures on items such as milk, eggs and meat which negatively affected company earnings for much of 2016. However, as stated above, fears of further deflation eased following the U.S. presidential election, and the stock was able to recover. Healthcare technology solutions provider Cerner was also a top detractor from the Fund’s relative performance for the year after reporting financial results below consensus expectations late in the year amid lower IT spending by hospitals, the company’s primary customers. Other top detractors were Apple (Information Technology), Red Hat (Information Technology) and Chipotle Mexican Grill (Consumer Discretionary). Top contributors to the Fund’s performance were rail operator Union Pacific and semiconductor manufacturer Texas Instruments. Union Pacific outperformed the Index mostly in the second half of 2016 due to improving trends in its underlying business. The stock performed particularly well following the election as investors gravitated to companies that would benefit the most from an improvement in the U.S. economy. Texas Instruments outperformed the Index for the year after several consecutive quarters in which it reported earnings that beat consensus expectations, primarily driven by continued improvement in operating margins. The Fund’s positions in IDEXX Laboratories and UnitedHealth Group were the primary drivers of positive stock selection effect in the Heath Care sector, and the Fund’s position in Schlumberger (Energy) was also a top contributor to the Fund’s performance.

  AN OVERVIEW FROM THE PORTFOLIO MANAGERS

Robert C. Lanphier, IV

 



David P. Ricci

The William Blair Mid Cap Growth Fund (Class N shares) posted a 0.23% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell Midcap® Growth Index (the “Index”), increased 7.33%.

 

Underperformance for 2016 versus the Index was due to a combination of style and stock-specific factors. From a style perspective, there were headwinds early in the year when investor preference for high dividend-yielding stocks dominated the market. While the preference for dividend yield was most pronounced at the beginning of the year, relative performance of high dividend-yielding stocks did not subside for the remainder of 2016 and high dividend-yielding stocks materially outperformed low dividend-yielding stocks in 2016. More economically-sensitive areas of the market also outperformed for the year, particularly in the third quarter and following the U.S. presidential election. The Fund tends to be significantly underweight high dividend yielding and more economically-sensitive companies, preferring sustainable growth companies with substantial reinvestment opportunities that enable superior, durable long-term growth. From a stock-specific perspective, the largest detractor from the Fund’s relative performance was apparel company Hanesbrands. The stock underperformed the Index for the year as issues related to inventory restocking and soft organic growth were exacerbated by concerns late in the year regarding risks related to international manufacturing. Drugmaker Perrigo was also a top detractor for the year. CEO turnover and weakness in its European consumer healthcare business were the primary causes for the stock lagging in 2016. Other top detractors from relative performance were Cerner (Health Care), Mead Johnson Nutrition (Consumer Staples) and Red Hat (Information Technology). Top contributors to relative performance for the year were trucking company Old Dominion Freight Line and aggregates producer Vulcan Materials. Old Dominion Freight Line outperformed the Index mainly due to better-than-expected earnings in the latter half of the year. Also, the stock outperformed the index as investors gravitated towards more economically-sensitive stocks. Vulcan Materials outperformed the Index after reporting strong volumes and pricing mid-year and amid investor optimism late in 2016 that infrastructure spending in the U.S will likely rise in the short to intermediate term. Other top contributors to the Fund’s relative performance were Akamai Technologies (Information Technology), Vantiv (Information Technology) and Align Technology (Health Care).

  The Mid Cap Value Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   



Chad M. Kilmer

 



Mark T. Leslie

 



David S. Mitchell

The William Blair Mid Cap Value Fund (Class N shares) posted a 14.49% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell Midcap® Value Index (the “Index”), increased 20.00%.

 

The Fund’s underperformance relative to the Index was driven by a combination of style factors and stock selection. The risk-on rally that began in mid-February continued on through the end of the year, led by smaller cap stocks and companies with slower growth. As such, our relative value style, which typically has a higher growth profile than the Index and an underweight to deep value stocks, was a headwind for the Fund. In addition, the worst performing stocks over the twelve months heading into the back half of 2016 rallied and the Fund’s lack of exposure to this segment was a headwind. At the sector level, Consumer Discretionary was the most significant detractor from the Fund’s relative performance due to stock selection within Specialized Consumer Services, Homebuilding, and Housewares & Specialties. Within the Real Estate sector, stock selection in Real Estate Services and Retail REITs contributed to the Fund’s underperformance. In general, REITs underperformed the rest of the market for the year due to the move up in interest rates during the back half of the year. The Industrials sector also detracted from the Fund’s relative performance during the year, mainly driven by the Fund’s lack of exposure to Airline stocks, which benefitted from better economic data and travel estimates given the pickup in business confidence. Broadly speaking, our higher quality bias and lack of exposure to the more cyclically exposed companies contributed to the Fund’s relative underperformance within Industrials as well. Financials was the most significant sector contributor to the Fund’s relative performance for the year due to stock selection within Property & Casualty Insurance. The Fund’s lack of exposure to Biotech and Pharmaceutical stocks contributed to the Fund’s outperformance within the Health Care sector during the period. With our focus on free cash flow and return on invested capital, most companies in these industries fail to meet our criteria. Looking specifically at stock selection, the Fund’s largest detractors from relative performance were Jones Lang LaSalle (Real Estate), Kroger (Consumer Staples), and H&R Block (Consumer Discretionary). Offsetting these detractors were our investments in Steel Dynamics (Materials), Patterson-UTI Energy (Energy), and Belden (Information Technology), which contributed to the Fund’s relative performance.

  AN OVERVIEW FROM THE PORTFOLIO MANAGERS

Robert C. Lanphier, IV

The William Blair Small-Mid Cap Growth Fund (Class N shares) posted a 6.45% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell 2500TM Growth Index (the “Index”), increased 9.73%.

 

Underperformance for 2016 versus the Index was mostly due to individual stock dynamics as style factors were largely offsetting. From a style perspective, the Fund’s typical larger market cap profile relative to the Index was a headwind to performance as the smaller end of the Fund’s capitalization range outperformed. Further, more economically-sensitive areas of the market outperformed for the year. This dynamic was a headwind to the Fund’s investment style as the Fund’s emphasis on companies with durable growth drivers typically results in a portfolio with less cyclicality than the Index. The impact of these style headwinds was most pronounced in the third quarter, during which the Fund underperformed by more than it did for the year as a whole. Mostly offsetting the aforementioned headwinds was a benefit from the Fund’s typical underweight to Biotechnology and Pharmaceuticals, which underperformed in 2016 following several years of strong returns. From a stock-specific perspective, Information Technology was an area of weakness for the year, including the Fund’s positions in Guidewire Software and Cvent. Given the stock’s higher valuation multiple and several sources of near-term business uncertainty, Guidewire Software underperformed. Other notable detractors from relative performance included Jones Lang LaSalle (Real Estate), Centene (Health Care) and Tractor Supply Company (Consumer Discretionary). Shares of Jones Lang LaSalle declined as investors began to fear a peak in earnings associated with extended strength in the commercial real estate market. Conversely, stock selection within the Health Care sector contributed positively to the Fund’s relative returns. IDEXX Laboratories and Align Technology were among the top Health Care sector contributors. Shares of IDEXX Laboratories advanced following the company’s successful transition to a direct selling model and an acceleration in organic growth. Other strong performing holdings included Old Dominion Freight Line (Industrials), Nu Skin Enterprises (Consumer Staples) and Diamondback Energy (Energy). Old Dominion Freight Line outperformed the Index due to better-than-expected earnings in the latter half of the year and as investors gravitated towards more economically-sensitive stocks.

December 31, 2016 William Blair Funds 23
 
  Small-Mid Cap Value Fund
   
  The Small-Mid Cap Value Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Chad M. Kilmer

 

 

Mark T. Leslie

 

 

David S. Mitchell

The William Blair Small-Mid Cap Value Fund (Class N shares) posted a 20.69% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell 2500™ Value Index (the “Index”), increased 25.20%.

 

The Fund’s underperformance relative to the Index was driven by a combination of style factors and stock selection. The risk-on rally that began in mid-February continued on through the end of the year, led by smaller cap, lower quality and higher beta stocks. As such, our relative value style, lower beta exposure, and underweight to the smallest market cap stocks in the universe, relative to the Index, were headwinds for the Fund. In addition, the worst performing stocks over the twelve months heading into the back half of 2016 rallied and the Fund’s lack of exposure to this segment was a headwind. At the sector level, Real Estate, specifically REITs, was the largest detractor from the Fund’s relative performance due to stock selection as REITs in general were pressured by the move up in interest rates during the back half of the year. Within REITs, an overweight to and stock selection within Retail REITs was the main driver of underperformance. While the Industrials sector represented a significant detractor from the Fund’s relative performance due to stock selection throughout most industries within the sector, our stock selection in the Aerospace & Defense industry was one of the largest contributors to relative performance in 2016. Broadly speaking, our higher quality bias and lack of exposure to the more cyclically exposed companies contributed to the Fund’s relative underperformance within Industrials as well. While the Fund’s cash position is a residual of our investment process, the robust market return for the year created a notable cash drag on relative performance. Information Technology was the most significant sector contributor to relative performance during the year due to strong stock selection within Semiconductors, where the Fund benefitted from the acquisition of portfolio holding Intersil earlier in the year. The Consumer Discretionary sector was another notable contributor to the Fund’s relative performance, mainly due to stock selection within Media and Hotels, Restaurants & Leisure. Looking specifically at stock selection, the Fund’s largest detractors from relative performance were Jones Lang LaSalle (Real Estate), Gulfport (Energy), and Integer (Health Care). Offsetting these detractors were investments in Inphi (Information Technology), Intersil (Information Technology), and Children’s Place (Consumer Discretionary), which contributed to the Fund’s relative performance.

December 31, 2016 William Blair Funds 27
 
  Small Cap Growth Fund
   
  The Small Cap Growth Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   


Michael P. Balkin

 


Karl W. Brewer

 


Ward D. Sexton

The William Blair Small Cap Growth Fund (Class N shares) posted an 18.89% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell 2000® Growth Index (the “Index”), increased 11.32%.

 

Significant outperformance in 2016 versus the Index was the result of both strong stock selection and style tailwinds for the Fund. From a style perspective, the Fund’s typical smaller market capitalization profile, relative to the Index, was a modest benefit while the Fund’s underweight allocations to Biotechnology and Pharmaceuticals provided a more significant tailwind as those industries underperformed in 2016. What had been a headwind to performance in prior years became a substantial tailwind in 2016 given the magnitude of our Biotechnology and Pharmaceuticals underweight, which has historically been driven by the relatively limited number of companies in those industries that satisfy our quality growth mandate. On a stock specific basis, selection was positive across several sectors, most notably in Health Care where ExamWorks, which was acquired in 2016, was the top contributor to the Fund’s relative performance. Other standout performers included Hudson Technologies (Industrials), Stillwater Mining Company (Materials), MaxLinear (Information Technology) and Xactly (Information Technology). Hudson Technologies outperformed after winning a large contract for new business and on optimism for continued strength in business fundamentals. Conversely, top detractors from relative performance during the year were Akorn (Health Care), Hortonworks (Information Technology), Virtu Financial (Financials), Air Methods Corporation (Health Care) and Guidewire Software (Information Technology). Akorn underperformed in part on investor concerns related to the restatement of the company’s financials while Hortonworks underperformed after announcing a dilutive secondary offering.

  AN OVERVIEW FROM THE PORTFOLIO MANAGERS

Mark T. Leslie

 

 

David S. Mitchell

The William Blair Small Cap Value Fund (Class N shares) posted a 26.19% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Russell 2000® Value Index (the “Index”), increased 31.74%.

 

The Fund’s underperformance relative to the Index was driven by a combination of style factors and stock selection. The risk-on rally that began in mid-February continued on through the end of the year, led by smaller cap, lower quality and higher beta stocks. As such, our larger market cap, higher quality biases and lower beta exposure were headwinds for the Fund. In addition, the worst performing stocks over the twelve months heading into the back half of 2016 rallied and the Fund’s lack of exposure to this segment was a headwind. At the sector level, Materials was the largest detractor from the Fund’s relative performance primarily due to a lack of exposure to Silver. An underweight to Steel, and stock selection within Steel, also detracted from relative performance. The Real Estate sector, specifically REITs, was another detractor from performance due to stock selection as REITs in general were pressured by the move up in interest rates during the back half of the year. While the Fund’s cash position is a residual of our investment process, the robust market return for the year created a notable cash drag on relative performance. Consumer Discretionary was the most significant sector contributor to the Fund’s relative performance during the year due to positive stock selection throughout the sector. The Energy sector was another notable contributor to relative performance, mainly due to stock selection within Oil, Gas & Consumable Fuels. Looking specifically at stock selection, the Fund’s largest detractors from relative performance were Integer (Health Care), Matson (Industrials), and TETRA Technologies (Energy). Offsetting these detractors were our investments in G&K Services (Industrials), Inphi (Information Technology), and Krispy Kreme Doughnuts (Consumer Discretionary), which contributed to the Fund’s relative performance.

Global Markets Review and Outlook

 

Global equities overcame repeated slumps in 2016 amid an environment of heightened political risk and fragile growth. Stock markets around the world sustained a swift and painful correction to start the year, driven by concerns about global growth and the plummeting oil price. China’s economic slowdown and ongoing rebalancing also weighed on sentiment, compounded by worries about the weaker renminbi and opaque government policy measures. These fears quickly abated, and markets rallied strongly off their February lows into mid-year, when the U.K. referendum on European Union membership came into focus.

 

Although Brexit-induced losses in late June were quickly recovered on expectations of prolonged central bank stimulus measures, the environment for equities remained tenuous heading into the second half of 2016, with uncertainty about the longer-term Brexit ramifications for U.K. and European economic activity. In addition to the surprise referendum outcome and its implications for growth, investors were confronted with renewed worries about systemic risk in the European banking system as Deutsche Bank’s share price retreated on news that the U.S. Department of Justice was seeking $14 billion to settle a mortgage-abuse case. Expectations that these concerns would give the Federal Open Market Committee more reason to delay interest rate normalization, or convince the European Central Bank to expand its stimulus measures, contributed to a risk-on environment during the third quarter, broadly propelling equities higher.

 

In what was perhaps the defining moment of 2016, Donald Trump’s election victory shifted the market’s focus from monetary policy to fiscal expansion, igniting a strong rally in reflationary assets through the end of the year. U.S. equities, the dollar and commodities were among the primary beneficiaries of expected infrastructure spending increases and tax cuts under the new administration, while rising inflation and interest rate expectations led to a sharp repricing of sovereign bond yields.

 

Emerging Markets equities outperformed Developed Markets in 2016, benefiting from reasonable valuations versus Developed Markets, stabilizing fund flows and currencies, moderating political risk, and the rebound in commodity prices. Despite stumbling in the fourth quarter on Trump-related worries about a stronger dollar, higher U.S. interest rates and protectionism, the MSCI Emerging Markets Index (net) gained 9.90% in USD terms for the year. Consistent with the market’s preference for low valuation stocks, previously out-of-favor countries and sectors rallied significantly during the year. Brazilian and Russian equities outperformed in this environment, gaining 66.10% and 56.95%, respectively, in USD terms, driven largely by currency appreciation. From a sector perspective within Emerging Markets, Energy and Materials gained 35.41% and 29.65%, respectively, leading other sectors by a wide margin.

 

The broadening global growth and inflationary backdrop contributed to the substantial outperformance of value-oriented stocks across regions, sectors, and market capitalizations in 2016. This trend accelerated after the U.S. Presidential election, to the detriment of not only growth-oriented companies, but those with higher quality attributes including balance sheet strength and low earnings volatility.

 

At our recent Global Market Outlook presentation to clients, we noted that financial markets have been correctly reacting to the global economic environment. Inflation has returned to pre-crisis levels in the U.S., while real growth has stabilized for the world economy overall – albeit at relatively low levels. This stabilization is remarkable because it comes on the back of two and a half years of a sharp and protracted deceleration in growth. Combined with sequentially rising inflation, this stabilization means nominal growth for the world as a whole is gradually increasing.

 

Now that inflation is becoming more apparent, we believe that re-pricing in the bond market has only just begun. Higher inflation also matters for equity returns. At a minimum, higher inflation implies higher interest rates, which influences the discount rate for future cash flows. In practical terms, we have already seen a sharp rotation toward “value” stocks, including cyclical sectors such as Industrials and Financials which had underperformed for several years before 2016, making them relatively “cheap” or “value-like”.

 

Valuation sensitivity has increased across geographies and sectors. Looking at the traditional discounted cash flow framework, the three main elements are suddenly working against investors with long-life assets: the terminal multiple is probably coming down; the cost of capital seems to be heading up; and free cash flows are under pressure from taxes and protectionism. In this environment, we have been adding to high-quality companies with a focus on lower valuations. Our preference remains for high-quality growth, but we believe the available opportunity set has expanded, and some of those companies are in cheaper areas of the market.

 

Despite near-term uncertainty surrounding how a Trump administration and Republican majority may actually govern, we expect a continuation of the recent reflationary market environment in 2017. From a global portfolio strategy perspective, we continue to expect higher nominal growth and have generally positioned toward companies with rising earnings prospects that we believe are not fairly reflected in valuations. In addition to the Industrials, Energy and Materials sectors, we continue to be constructive on Financials, supported by higher rates and steeper yield curves – which we believe are likely to persist.

 

Specific to Emerging Markets, several factors are supportive of our 2017 outlook. Valuations remain attractive, with Emerging Markets equities overall trading at a 25% discount to Developed Markets (based on forward P/E multiples), about one standard deviation below their long-term average. After stagnating over the last few years, Emerging Market corporate earnings are forecast to increase at a low double-digit pace this year. From an external balance perspective (the difference between exports of goods and services and imports of goods and services), Emerging Markets currencies have already depreciated and current account deficits have moderated.

 

Key risk factors for Emerging Markets that bear close monitoring are a strengthening U.S. dollar and acceleration in U.S. interest rate hikes, in addition to protectionist measures that impede global trade. China’s capital outflows and currency management policy, as well as the lingering effects of India’s demonetization on local economic activity, will also be important risk considerations for Emerging Markets investors in 2017.

  AN OVERVIEW FROM THE PORTFOLIO MANAGERS

Kenneth J. McAtamney

The William Blair Global Leaders Fund (Class N shares) posted a 0.62% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI All Country World IMI Index (net) (the “Index”), increased 8.36%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of low valuation market leadership. From a sector attribution perspective relative to the Index, stock selection in Materials, Real Estate, Healthcare and Industrials were significant detractors from the Fund’s relative performance for the year. These effects were mitigated by positive stock selection in Energy and the Fund’s underweight position to Consumer Staples. Within Materials, the Fund’s performance was hampered by a lack of exposure to Metals & Mining stocks, which rallied strongly on global growth recovery prospects and the market’s rotation into value orientated stocks. Chemicals holdings also detracted from the Fund’s relative performance in the Materials sector. Within the Real Estate sector, property developer China Overseas Land & Investment’s share price was hampered by concerns about policy tightening measures in Shanghai and other mainland cities. U.S.-based commercial real estate company Jones Lang LaSalle also detracted from relative performance, as weaker investment sales, elevated expenses and currency effects weighed on financial results. Within the Health Care sector, U.S. managed care provider Centene’s share price weakened amid policy uncertainty following the Republican party sweep in November. Partially offsetting these effects were positive contributions to the Fund’s performance from Oil & Gas holdings, including Canadian oil sands producer Suncor Energy, which reported solid financial results driven by higher production and operational improvements. U.S.-based shale driller EOG Resources also contributed to the Fund’s relative performance, bolstered by better than expected crude oil production results, as well as production growth guidance. From a geographic attribution perspective, the primary detractor from relative performance in 2016 was U.S. stock selection, as the Fund’s U.S. Financials, Information Technology and Real Estate holdings lagged. In contrast, stock selection in Japan was positive, supported by the outperformance of the Japanese Industrials, Information Technology and Financials sectors, relative to the Index.

AN OVERVIEW FROM THE PORTFOLIO MANAGERS

 

The William Blair International Leaders Fund (Class N shares) posted a 0.88% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI All Country World ex-U.S. IMI Index (net) (the “Index”), increased 4.41%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of low valuation market leadership. From a sector attribution perspective, stock selection in Financials, Materials, Real Estate and Consumer Staples were significant detractors from the Fund’s performance relative to the Index for the year. These effects were mitigated by positive stock selection in Healthcare and Consumer Discretionary, the Fund’s underweight position in Consumer Staples and overweight in Information Technology. Financials stock selection detracted from the Fund’s relative performance partially due to holdings in Intesa Sanpaolo (Italy) and Sumitomo Mitsui Financial Group (Japan), which declined on concerns about profitability amid the low interest rate environment. Within the Materials sector, the Fund’s performance was hampered by a lack of exposure to Metals & Mining stocks, which rallied strongly on global growth recovery prospects and the market’s rotation into value orientated stocks. Automobile catalyst chemical maker Johnson Matthey (U.K.) also detracted from the Fund’s performance, as the shares were hit by general Brexit-related concerns and the impact of weaker platinum prices on its metals refining business. Within the Real Estate sector, property developer China Overseas Land & Investment’s share price was weighed down by concerns about policy tightening measures in Shanghai and other mainland cities. Finally, within Consumer Staples, Wal-Mart de Mexico’s shares came under pressure in the second half of 2016 amid decelerating top line growth and general concerns about the impact of Donald Trump’s policies on the Mexican economy. Mitigating these negative effects were positive stock selection effects in the Healthcare sector, as Swiss biotechnology company Actelion benefited from positive sales trends in its pulmonary arterial hypertension (PAH) drugs Uptravi and Opsumit, in addition to news that the company was in merger talks with French pharmaceutical company Sanofi after Johnson & Johnson dropped its own takeover offer for Actelion. Regarding stock selection within the Consumer Discretionary sector, Japanese home furnishings retailer Nitori’s share price was supported by positive sales trends on a combination of new store openings, same-store sales growth and online sales growth. From a geographic attribution perspective, stock selection was weakest in Canada and Latin America for the year, partially mitigated by good stock selection in Japan and Emerging Asia.

  The International Equity Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

David Merjan

 

 

John C. Murphy

 

 

The William Blair International Equity Fund (Class N shares) posted a 0.27% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI World ex-U.S. Index (net) (the “Index”), increased 2.75%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of low valuation market leadership. From a sector attribution perspective, stock selection in Industrials, Financials and Consumer Staples were significant detractors from the Fund’s performance relative to the Index for the year. These effects were mitigated by positive stock selection in Energy and Real Estate, along with the Fund’s overweight position and stock selection in Information Technology. Within the Industrials sector, U.K. holdings were the primary detractor from the Fund’s relative performance during the year. British home improvement retailer Travis Perkins’s share price was hurt by Brexit concerns mid-year, followed by sluggish sales in the company’s plumbing and heating division during the third quarter. Within Financials, Japanese Commercial Bank Mitsubishi UFJ Financial Group detracted from the Fund’s performance during the first half of the year, amid concerns about the impact of the Bank of Japan’s (BOJ’s) negative interest rate policy on earnings. Stock selection within Consumer Staples, specifically the Fund’s position in Belgium-based brewing giant Anheuser-Busch Inbev which reported disappointing third quarter earnings results mainly due to its Brazil business, detracted from performance. Within Brazil, Anheuser-Busch Inbev attributed its difficulties to several factors including the continued challenging consumer environment, negative currency hedging impact, delayed price increases and higher marketing expenses. Offsetting these detractors were positive contributions to the Fund’s relative performance from North American Oil & Gas producers Enerplus and Canadian Natural Resources, which were supported by rising commodity prices and improving production growth outlooks. Specific to Enerplus, the prospect of a potential sale of the company’s Marcellus shale assets was viewed favorably, with expectations that the sale proceeds would be used for debt reduction or an earnings-accretive acquisition. Among the Fund’s Real Estate holdings, Japan-based REIT Nippon Prologis’s share price was bolstered by the BOJ’s negative interest rate policy, which was expected to support margins by ensuring a favorable spread between financing costs and rental yields. The company also reported better-than-expected financial results for the first half of 2016, benefiting from high occupancy levels and positive rental growth for its logistics facilities. From a geographic attribution perspective, the primary detractors from the Fund’s relative performance in 2016 were stock selection within Japan and an overweighting in the U.K. These effects were partially mitigated by positive stock selection in Canada, along with the Fund’s Emerging Markets exposure.

The William Blair Institutional International Equity Fund posted a 0.27% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI World ex-U.S. Index (net) (the “Index”), increased 2.75%.

  The International Growth Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Stephanie G. Braming

 

 

Simon Fennell

 

 

Jeffrey A. Urbina

The William Blair International Growth Fund (Class N shares) posted a 2.88% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI All Country World ex-U.S. IMI Index (net) (the “Index”), increased 4.41%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of low valuation market leadership. From a sector attribution perspective, stock selection in Financials, Materials and Real Estate were significant detractors from the Fund’s performance relative to the Index for the year. These effects were mitigated by positive stock selection in Healthcare, along with an overweight position in Information Technology and underweight positions in Real Estate and Utilities. Within Financials, stock selection in Banks and Insurance detracted from the Fund’s relative performance. Within Materials, the Fund’s performance was hampered by a lack of exposure to Metals & Mining stocks, which rallied strongly on global growth recovery prospects and the market’s rotation into value orientated stocks. Chemicals holdings also detracted from the Fund’s relative performance in the Materials sector. Within the Real Estate sector, U.K. REIT Derwent London, which owns, develops and refurbishes properties in central London, was negatively impacted by concerns of slowing demand for London office space due to Brexit. Property developer China Overseas Land & Investment’s share price was hampered by concerns about lending policy tightening measures in Shanghai and other mainland cities, despite the company’s strong revenue and operating profit growth trends. Within the Healthcare sector, Swiss biotechnology company Actelion benefited from positive sales trends in its pulmonary arterial hypertension (PAH) drugs Uptravi and Opsumit, in addition to news that the company was in merger talks with French pharmaceutical company Sanofi after Johnson & Johnson dropped its own takeover offer for Actelion. From a geographic attribution perspective, the primary detractors from the Fund’s relative performance in 2016 were stock selection within Japan, notably within Japanese Consumer Discretionary stocks, and the U.K., as the Fund’s U.K. Financials holdings lagged.

Performance cited represents past performance. Past performance does not guarantee future results and current performance may be lower or higher than the data quoted. Results shown are average annual total returns, which assume reinvestment of dividends and capital gains. Investment returns and principal will fluctuate and you may have a gain or loss when you sell shares. For the most current month-end performance information, please call 1-800-742-7272, or visit our Web site at www.williamblairfunds.com. Investing in smaller and medium capitalization companies involves special risks, including higher volatility and lower liquidity. Smaller and medium capitalization stocks are also more sensitive to purchase/sale transactions and changes in the issuer’s financial condition. International investing involves special risk considerations, including currency fluctuations, lower liquidity, economic and political risk. From time to time, the investment adviser may waive fees or reimburse expenses for the Fund. Without these waivers/reimbursements, performance would be lower. Class N shares are available to the general public without a sales load. Class I shares are available to certain institutional investors and advisory clients of William Blair Investment Management, LLC and William Blair & Company, L.L.C., without a sales load or distribution (12b-1) or service fees.

 

The performance highlights and graph presented above do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

  The Institutional International Growth Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Stephanie G. Braming

 

 

Simon Fennell

 

 

Jeffrey A. Urbina

The William Blair Institutional International Growth Fund posted a 2.40% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI All Country World ex-U.S. IMI Index (net) (the “Index”), increased 4.41%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of low valuation market leadership. From a sector attribution perspective, stock selection in Financials, Materials and Real Estate were significant detractors from the Fund’s performance relative to the Index for the year. These effects were mitigated by positive stock selection in Healthcare, along with an overweight position in Information Technology and underweight positions in Real Estate and Utilities. Within Financials, stock selection in Banks and Insurance detracted from the Fund’s relative performance. Within Materials, the Fund’s performance was hampered by a lack of exposure to Metals & Mining stocks, which rallied strongly on global growth recovery prospects and the market’s rotation into value orientated stocks. Chemicals holdings also detracted from the Fund’s relative performance in the Materials sector. Within the Real Estate sector, U.K. REIT Derwent London, which owns, develops and refurbishes properties in central London, was negatively impacted by concerns of slowing demand for London office space due to Brexit. Property developer China Overseas Land & Investment’s share price was hampered by concerns about policy tightening measures in Shanghai and other mainland cities, despite the company’s strong revenue and operating profit growth trends. Within the Healthcare sector, Swiss biotechnology company Actelion benefited from positive sales trends in its pulmonary arterial hypertension (PAH) drugs Uptravi and Opsumit, in addition to news that the company was in merger talks with French pharmaceutical company Sanofi after Johnson & Johnson dropped its own takeover offer for Actelion. From a geographic attribution perspective, the primary detractors from the Fund’s relative performance in 2016 were stock selection within Japan, notably within Japanese Consumer Discretionary stocks, and the U.K., as the Fund’s U.K. Financials holdings lagged.

66 Annual Report December 31, 2016
 
  International Small Cap Growth Fund
   
  The International Small Cap Growth Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Stephanie G. Braming

 

 

Andrew G. Flynn

The William Blair International Small Cap Growth Fund (Class N shares) posted a 4.60% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI All Country World ex-U.S. Small Cap Index (net) (the “Index”), increased 3.91%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of low valuation market leadership. From a sector attribution perspective, stock selection in Real Estate and Information Technology (IT) were the largest detractors from the Fund’s performance relative to the Index for the year. The Fund’s Real Estate stock selection was adversely impacted by holdings in U.K. Real Estate Investment Trusts, including Workspace Group and Big Yellow Group, both of which suffered from uncertainty surrounding Britain’s referendum on European Union membership and Brexit’s potentially detrimental impact on U.K. real estate activity. Within the IT sector, exposure to Electronic Equipment, Internet Software and Semiconductor companies weighed on the Fund’s relative performance. U.K.-based price comparison website Moneysupermarket.com was a primary detractor within the Internet Software industry, hampered by earnings downgrades following the Brexit vote and the announced departure of its CEO. Helping to offset these negative effects was the Fund’s positive stock selection in the Energy and Healthcare sectors, combined with its underweightings in Real Estate and IT. Within Energy, oil services company Canadian Energy Services was the primary contributor to the Fund’s performance, benefiting from analyst upgrades on an improving outlook for drilling activity. Within Healthcare, positive stock selection was supported by Japanese medical information services company M3, which benefited from strength in its medical portal division and improving profitability overseas. From a geographic attribution perspective, stock selection in Japan was the primary detractor from the Fund’s relative performance in 2016, mostly within the IT, Consumer Discretionary and Consumer Staples sectors. These negative effects were mitigated by favorable stock selection in Emerging Asia, as the Fund’s holdings in China and India outperformed.

Performance cited represents past performance. Past performance does not guarantee future results and current performance may be lower or higher than the data quoted. Results shown are average annual returns, which assume reinvestment of dividends and capital gains. Investment returns and principal will fluctuate and you may have a gain or loss when you sell shares. For the most current month-end performance information, please call 1-800-742-7272, or visit our Web site at www.williamblairfunds.com. From time to time, the investment adviser may waive fees or reimburse expenses for the Fund. Without these waivers/reimbursements, performance would be lower. Smaller capitalization stocks are also more sensitive to purchase/sale transactions and changes in the issuer’s financial condition.

72 Annual Report December 31, 2016
 
  Emerging Markets Leaders Fund
   
  The Emerging Markets Leaders Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Todd M. McClone

 

 

John C. Murphy

 

 

Jeffrey A. Urbina

The William Blair Emerging Markets Leaders Fund (Class N shares) posted a 1.42% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI Emerging Markets Index (net) (the “Index”), increased 11.19%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of significant low valuation market leadership. From a sector attribution perspective stock selection in Financials and Materials, an underweight to Energy, and an overweight to Consumer Staples were the primary detractors from the Fund’s performance relative to the Index for the year. Within Financials, the Fund’s Bank holdings did not keep pace with the Index, hampered partially by the position in Turkiye Garanti Bankasi, which stumbled on broader macroeconomic and political risk in Turkey. Mexican bank exposure, including Grupo Financiero Inbursa which was sold from the Fund in the second quarter due to slowing loan growth, and Grupo Financiero Banorte which weakened along with Mexican banks following Donald Trump’s election victory, also detracted from the Fund’s relative performance as a result of concerns about corporate credit quality and a potential increase in non-performing loans. Within Materials, the Fund’s lack of exposure to Metals & Mining stocks was a significant detractor from relative performance during the year. These effects more than offset the positive contributions from the Fund’s stock selection in the Industrials sector and its underweight positions in Healthcare, Telecommunication Services and Materials. From a geographic attribution perspective, stock selection within Russia and Brazil were the largest detractors from the Fund’s relative performance in 2016, driven by a lack of exposure to strong performing Index holdings in the Metals & Mining and Oil & Gas industries. These effects offset positive contributions from the Fund’s stock selection in Malaysia, the Philippines and Taiwan, along with its underweight to China and overweights to Thailand and Peru.

The William Blair Emerging Markets Growth Fund (Class N shares) posted a 1.49% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI Emerging Markets IMI Index (net) (the “Index”), increased 9.90%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of significant low valuation market leadership. From a sector attribution perspective, stock selection in Financials and Materials, an underweight to Energy, and an overweight to Consumer Staples were the primary detractors from the Fund’s performance relative to the Index for the year. Within Financials, the Fund’s Bank holdings did not keep pace with the Index, hampered partially by the position in Turkiye Garanti Bankasi which stumbled on broader macroeconomic and political risk in Turkey. Mexican bank exposure, including Grupo Financiero Inbursa which was sold from the Fund in the third quarter due to slowing loan growth, and Grupo Financiero Santander Mexico which weakened along with Mexican banks following Donald Trump’s election victory, also detracted from the Fund’s relative performance as a result of concerns about corporate credit quality and a potential increase in non-performing loans. Within Materials, the lack of exposure to Metals & Mining stocks was a significant detractor from the Fund’s performance during the year. These effects more than offset the positive contributions from the Fund’s stock selection in the Consumer Discretionary, Industrials, Telecommunication Services and Utilities sectors. India’s Tata Motors was a notable contributor within the Consumer Discretionary sector, bolstered by accelerating volume growth within its Jaguar division. Within Industrials, South African conglomerate Bidvest Group benefited from investors’ favorable reaction to the spin-off of the company’s food business. From a geographic attribution perspective, stock selection within Russia and Brazil were the largest detractors from the Fund’s relative performance in 2016, driven by a lack of exposure to strong performing Index holdings in the Metals & Mining and Oil & Gas Industries. These effects offset positive contributions from the Fund’s stock selection in India and Malaysia, along with underweights to China and Korea.

December 31, 2016 William Blair Funds 83
 
  Emerging Markets Small Cap Growth Fund
   
  The Emerging Markets Small Cap Growth Fund seeks long-term capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Todd M. McClone

 

 

Casey K. Preyss

The William Blair Emerging Markets Small Cap Growth Fund (Class N shares) posted a 5.33% decrease, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the MSCI Emerging Markets Small Cap Index (net) (the “Index”), increased 2.28%.

 

Adverse style effects broadly detracted from the Fund’s calendar year 2016 performance versus the Index. The Fund’s overweight to higher growth, higher valuation companies with relatively strong earnings trends was detrimental amid an environment of significant low valuation market leadership. From a sector attribution perspective, stock selection in Industrials, Materials, Real Estate and Utilities were the primary detractors from the Fund’s performance relative to the Index for the year. Within the Industrials sector, the Fund’s Airline holdings underperformed, including Mexican low-cost carrier Controladora Vuela Compania de Aviacion (“Volaris”), which declined significantly in November on concerns about President-elect Trump’s policies potentially hurting future travel demand. Panamanian airline Copa Holdings also detracted from the Fund’s performance due to share price weakness in the first half of 2016 amid poor operating conditions and a tough macroeconomic backdrop, and lingering concerns about the company’s impending write down of its Venezuelan cash balance. Within the Materials sector, the Fund’s lack of Metals & Mining exposure detracted from relative performance. In addition, stock selection in Chemicals detracted from performance, as Berger Paints India’s share price pulled back in November due to worries about a slowdown in consumer spending related to the Indian government’s abrupt removal of high denomination currency notes from circulation. From a geographic attribution perspective, stock selection in Korea, Taiwan and China were the primary detractors from the Fund’s relative performance in 2016, although partially mitigated by underweight positions in each country. These negative stock selection effects offset positive contributions from stock selection in India, Turkey, and the United Arab Emirates, in addition to the positive contributions from the Fund’s exposure to Pakistan and overweight in Brazil.

Performance cited represents past performance. Past performance does not guarantee future results and current performance may be lower or higher than the data quoted. Results shown are average annual returns, which assume reinvestment of dividends and capital gains. Investment returns and principal will fluctuate and you may have a gain or loss when you sell shares. For the most current month-end performance information, please call 1-800-742-7272, or visit our Web site at www.williamblairfunds.com. From time to time, the investment adviser may waive fees or reimburse expenses for the Fund. Without these waivers/reimbursements, performance would be lower.

December 31, 2016 William Blair Funds 89
 
Fixed Income Market Review and Outlook

 

The Bloomberg Barclays U.S. Aggregate Index (the “Index”) gained 2.65% during 2016, and interest rates rose in small magnitude across the yield curve. This perhaps-unspectacular headline masks the volatility experienced during the year. During the first six months of the year, interest rates plummeted to levels near historical lows and the Index gained 5.31%. During the last six months of the year, interest rates rose, the fourth quarter was the worst-performing calendar quarter for the Index in over 30 years, and the Index declined 2.53%.

 

The Federal Reserve did, in fact, raise the federal funds rate, although not at the pace predicted at the beginning of 2016. In January 2016, the Eurodollar futures market predicted four interest rate hikes during the calendar year. The Federal Open Market Committee (“FOMC”) did increase the target range of the federal funds rate once during the year by 0.25%, to a range of 0.50% -0.75%, at its December meeting. The FOMC cited strengthening labor market conditions that were supported by both the decline in the unemployment rate and an increase in wage inflation. However, the FOMC also stated that monetary policy remains accommodative to allow some further strengthening in labor market conditions, and that future increases in the federal funds rate are expected to be gradual. At the end of 2016, interest rates in the eurodollar futures market predicted three FOMC interest rate hikes during calendar year 2017.

 

The FOMC also stated that it will continue its practice of reinvesting principal payments from its holdings of Treasuries, agency debt, and agency mortgage-backed securities (“MBS”). These purchases influence longer-term interest rates and MBS risk spreads. While the FOMC is striking a hawkish tone on the direction of short-term rates, these purchases provide stable or downward pressure on longer-term interest rates. Meanwhile, the risk spreads of lower-coupon MBS that the FOMC is purchasing are lower than those of other MBS coupons that are being determined by more-traditional market forces.

 

Fixed-rate Treasuries underperformed the other major segments of the Index during the year. U.S. Treasury Inflation-Protected Securities (“TIPS”) outperformed fixed-rate Treasuries as market-implied inflation expectations rose. The MBS Index underperformed Treasuries after controlling for the effects of duration, but higher-coupon segments of the MBS market outperformed comparable-duration Treasuries. Corporate securities outperformed Treasuries on a duration-adjusted basis. High yield corporate bonds generated a robust gain of 17.13% during the year.

 

We believe that the FOMC will raise the federal funds rate gradually in 2017. The U.S. economy is growing; forecasters predict a real GDP growth rate of approximately 2.0% during 2016 and 2017. In addition, the U.S. labor market is adding jobs at a robust pace. Wage inflation increased throughout 2016, and estimates peg wage growth at 3.5% – 4.0% year-over-year, a level above the 2.5% upper bound of the FOMC’s target inflation range. Macroeconomic theory predicts that a robust labor market creates wage inflation, which in turn spurs broader inflation. We believe that the FOMC will raise the federal funds rate if market conditions remain normal and wage inflation takes hold.

 

TIPS have market-implied breakeven inflation rates slightly below the FOMC’s stated target range of 2.0% – 2.5%, and they are also below recent wage inflation estimates. We believe TIPS are an attractive alternative to fixed-rate Treasuries for mitigating the effects of rising rates driven by accelerating inflationary pressures.

 

We believe that spread sectors are poised to lead the market over the longer term. Corporate risk premiums are at levels above their longer-term averages, and risk premiums of higher-coupon segments of the agency MBS market remain attractive. In addition, we believe Treasuries are likely to struggle as the FOMC embarks on a tightening cycle.

 

We believe that higher-coupon segments (coupon rates of 5.0% and above for 30-year) of the agency MBS market offer compelling value. These segments of the agency MBS market offer attractive spreads and a defensive duration profile. The key risk of these securities is that the underlying borrowers are in-the-money to refinance their loan. We believe this risk can be mitigated by focusing on pools comprised of borrowers that do not have the economic incentive to refinance their loans (e.g., low-loan balance pools).

 

We believe that the corporate bond market remains attractive. Although fundamentals have deteriorated lately, risk spreads remain at attractive levels on a historical basis. We observed an increase in leverage among industrial companies over the past year as companies secured financing at low nominal yields in the robust new issue market for corporate bonds. We remain concerned about company-specific risks, including shareholder-friendly activities such as leveraged finance mergers and acquisitions, large share repurchases, and special dividends. Importantly, we do not believe the market will enter a period of excessive leveraged buyout activity.

 

90 Annual Report December 31, 2016
 
  Bond Fund
  The Bond Fund seeks to outperform the Bloomberg Barclays U.S. Aggregate Index by maximizing total return through a combination of income and capital appreciation.
   
  AN OVERVIEW FROM THE PORTFOLIO MANAGERS
   

 

Paul J. Sularz

 

 

Christopher T. Vincent

The William Blair Bond Fund (Class N shares) posted a 4.40% return, net of fees, for the year ended December 31, 2016. By comparison, the Fund’s benchmark, the Bloomberg Barclays U.S. Aggregate Index (the “Index”), returned 2.65%.

 

Multiple factors contributed to the Fund’s outperformance relative to the Index. Security selection among the Fund’s corporate bond holdings contributed to the Fund’s outperformance, specifically positions in bonds issued by ConocoPhillips, YUM! Brands, Petrobras, and Mexichem. Sector allocation also contributed to relative performance, as the Fund was underweight to fixed-rate Treasuries and overweight corporate bonds. The Fund experienced positive security selection results from its agency mortgage-backed securities holdings. Finally, the Fund held a position in U.S. Treasury Inflation-Protected Securities that was additive to performance.

 

Detracting from the Fund’s relative performance in 2016 were exposures to bonds issued by Embraer and Credit Suisse.

96 Annual Report December 31, 2016
 
 

Income Fund

  
 The Income Fund seeks a high level of current income with relative stability of principal.
  
 AN OVERVIEW FROM THE PORTFOLIO MANAGER
  

 

Christopher T. Vincent

 

The William Blair Income Fund (Class N shares) returned 2.44%, net of fees, for the year ended December 31, 2016. By comparison, the Fund’s benchmark, the Bloomberg Barclays Intermediate Government/Credit Bond Index (the “Index”), returned 2.08%.

 

Multiple factors contributed to the Fund’s outperformance relative to the Index. The Fund’s positions in agency mortgage-backed securities contributed to relative performance, as those positions performed well relative to comparable-duration securities in the Index. Security selection among the Fund’s corporate bond holdings contributed to the Fund’s outperformance, specifically positions in bonds issued by ConocoPhillips, Masco, JP Morgan, Synchrony Financial, BRF SA, and Fibria Cellulose. Finally, an allocation to U.S. Treasury Inflation-Protected Securities was additive to performance.

 

Factors that detracted from the Fund’s relative performance in 2016 included an underweight to corporate bonds and BBB-rated securities, relative to the Index, both of which performed well during the year. In addition, the Fund held positions in bonds issued by Seagate Technology and Embraer that detracted from relative performance.

 

Please refer to the Fixed Income Market Review and Outlook relating to the Fund on page 90 for additional information.

100 Annual Report December 31, 2016
 
 

Low Duration Fund

   
 

The Low Duration Fund seeks to maximize total return. Total return includes both income and capital appreciation.

   
 

AN OVERVIEW FROM THE PORTFOLIO MANAGERS

   

 

Paul J. Sularz

 

 

Christopher T. Vincent

The William Blair Low Duration Fund (Class N shares) returned 1.16%, net of fees, for the year ended December 31, 2016. By comparison, the Fund’s benchmark, the Bank of America Merrill Lynch 1-Year U.S. Treasury Note Index (the “Index”), returned 0.76%.

 

Multiple factors contributed to the Fund’s outperformance relative to the Index. The Fund is designed to assume slightly more interest rate risk than the risk-free rate, and the Fund’s interest rate exposures contributed to relative performance as shorter-term interest rates generated positive returns during the year. Fund holdings in agency mortgage-backed securities were a contributing source of performance. Finally, allocations to floating-rate asset-backed and investment-grade corporate securities had a positive impact on performance.

 

Factors that detracted from the Fund’s relative performance in 2016 included interest rate risk hedging and residual cash.

 

Please refer to the Fixed Income Market Review and Outlook relating to the Fund on page 90 for additional information.

Macro Allocation Fund

 

AN OVERVIEW FROM THE PORTFOLIO MANAGERS

   

 

Thomas Clarke

 

 

Brian D. Singer

The William Blair Macro Allocation Fund (Class N shares) posted a 2.01% increase, net of fees, for the twelve months ended December 31, 2016. By comparison, the Fund’s benchmark index, the Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index and the Long-Term Comparative Index (40% Bloomberg Barclays U.S. Aggregate Index, 30% MSCI All Country World Index (net) and 30% Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index), increased 0.33% and 3.68%, respectively.

 

The Fund had flat performance from its market strategy (i.e., equity and fixed income) and positive performance from its currency strategy. Detractors from the Fund’s market-oriented exposures included positioning within U.S. equities, which mostly resulted from the Fund’s preference for large cap equities over small cap equities, and short exposure to Japanese equities. Long exposure to European equities contributed to the Fund’s gains, particularly a preference for European financial sector equities in the second half of the year. The Fund also benefitted from long exposure to U.S. credit. Within currency, long exposures to emerging currencies were beneficial to the Fund’s performance, with strong performance coming from exposures to the Russian ruble, Brazilian real, and Indonesian rupiah. This was partially offset by a negative contribution from long exposure to the Mexican peso and Malaysian ringgit.

 

2016 was a year filled with geopolitical uncertainty and a year in which thematic influences (such as Populism) remained quite intense. Areas of geopolitical focus that warranted navigation included the UK as it wrestled with the Brexit vote and the second Spanish election, both taking place in late June. Additional areas of focus were the U.S. presidential election and the Italian referendum, both of which took place late in the year.

 

We feel compelled to remain relatively cautious in the domain of systematic (or beta-like) market risk, and to maintain lower risk exposures to attractive emerging markets currencies than would otherwise be the case due to our assessment that the forward-looking risk environment still remains somewhat elevated in general. However, we have begun to increase risk in the Fund’s portfolio in some places where shorter-term macro-thematic and geopolitical headwinds have abated.

 

The Fund’s market strategy remains moderately long in equities with exposures to Europe, U.K., and emerging markets, while also moving to a slightly long exposure in the U.S. The market strategy is also slightly short in fixed income securities, with long exposure to emerging markets debt offset by short exposure to European government bonds.

 

Within currencies, the Fund’s strategy remains long in emerging currencies and short in developed currencies, which is in line with fundamental valuation. The Fund’s long currency positions include the Colombian peso, Mexican peso, and Philippine peso, and the largest short positions are in the Swiss franc, New Zealand dollar, and Canadian dollar.

Notes to Financial Statements

 

(1) Organization

 

(a) Description of the Trust

 

William Blair Funds (the “Trust”) is a mutual fund registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust currently consists of the following twenty-two funds (the “Funds”), each with its own investment objective and policies. For each Fund, the number of shares authorized is unlimited.

Prior to July 1, 2015, William Blair & Company, L.L.C. (“WBC” or the “Distributor”) served as both the Trust’s investment adviser and the Trust’s principal underwriter and distributor. Effective July 1, 2015, WBC transferred the management agreement for the Trust to William Blair Investment Management, LLC (“WBIM”). There were no changes to the Funds’ portfolio management teams or principal investment strategies as a result of the transfer. Any reference to the “Adviser” prior to July 1, 2015 should be read to mean WBC; any reference to the “Adviser” subsequent to July 1, 2015 should be read to mean WBIM. WBC continues to serve as the principal underwriter and distributor of the Trust.

 

(b) Share Classes

 

Three different classes of shares currently exist: N, I and Institutional.

 

Class N shares are offered to the general public, either directly through the Trust’s distributor or through a select number of financial intermediaries. Class N shares are sold without any sales load, and carry an annual 12b-1 distribution fee (0.25% for the Domestic Equity, Global Equity, International Equity and Multi-Asset and Alternative Funds and 0.15% for the Fixed Income Funds), a sub-transfer agent fee that is not a fixed rate and may vary by Fund and class, and an annual shareholder administration fee (0.15% for Global Leaders, International Leaders, International Small Cap Growth, Emerging Markets Leaders, Emerging Markets Growth, Emerging Markets Small Cap Growth, Bond, Low Duration and Macro Allocation Funds). The shareholder administration fee is currently being waived. This waiver will not be removed without approval of the Board of Trustees.

 

Class I shares are offered to a limited group of investors. They do not carry any sales load or distribution fees and generally have lower ongoing expenses than Class N shares. Class I shares have a sub-transfer agent fee that is not a fixed rate and may vary by Fund and class, and an annual shareholder administration fee (0.15% for Global Leaders, International Leaders, International Small Cap Growth, Emerging Markets Leaders, Emerging Markets Growth, Emerging Markets Small Cap Growth, Bond, Low Duration and Macro Allocation Funds). The shareholder administration fee is currently being waived. This waiver will not be removed without approval of the Board of Trustees.

 

Institutional Class shares are offered to institutional investors, including but not limited to employee benefit plans, endowments, foundations, trusts and corporations, who are able to meet the share class’s high minimum investment requirement. The minimum initial investment required is $5 million. They do not carry any sales load, distribution fees or sub-transfer agents fees and generally have lower ongoing expenses than Class N and Class I shares.

 

130 Annual Report December 31, 2016
 

Sub-transfer agent fees: For Class N and Class I shares, the Funds may reimburse WBC for fees paid to intermediaries such as banks, broker-dealers, financial advisers or other financial institutions for sub-administration, sub-transfer agency and other services provided to investors whose shares of record are held in omnibus, other group accounts, retirement plans or accounts traded through registered securities clearing agents. These fees may vary based on, for example, the nature of services provided, but generally range up to 0.15% of the assets of the class serviced or maintained by the intermediary or up to $15 per sub-account maintained by the intermediary.

 

(c) Fund Objectives

 

The investment objectives of the Funds are as follows:

 

Domestic Equity Long-term capital appreciation.
Global Equity Long-term capital appreciation.
International Equity Long-term capital appreciation.
Fixed Income High level of current income with relative stability of principal.
  (Maximize total return-Low Duration).
Multi-Asset and Alternative Maximize long-term risk-adjusted total return.

 

(2) Significant Accounting Policies

 

The following is a summary of the Trust’s significant accounting policies in effect during the periods covered by the financial statements, which are in accordance with U.S. generally accepted accounting principles, which includes the accounting and reporting guidelines under Accounting Standards Topic 946, Financial Services—Investment Companies.

 

(a) Investment income and transactions

 

Investment income, realized and unrealized gains and losses, and certain Fund level expenses and expense reductions, if any, are allocated based on the relative net assets of each class, except for certain class specific expenses, which are charged directly to the appropriate class. Differences in class expenses may result in the payment of different per share dividends by class. All share classes of the Funds have equal rights with respect to voting, subject to class specific arrangements.

 

Dividend income and expense are recorded on the ex-dividend date, except for those dividends from certain foreign securities that are recorded when the information is available.

 

Interest income is recorded on an accrual basis, adjusted for amortization of premium or accretion of discount. Variable rate bonds and floating rate notes earn interest at coupon rates that fluctuate at specific time intervals. The interest rates shown in the Portfolio of Investments for the Bond, Income, Low Duration and Macro Allocation Funds were the rates in effect on December 31, 2016. Put bonds may be redeemed at the discretion of the holder on specified dates prior to maturity.

 

Premiums and discounts are amortized and accreted on a straight-line basis for short-term investments and on an effective interest method for long-term investments.

 

Paydown gains and losses on mortgage-backed and asset-backed securities are treated as an adjustment to interest income. For the year ended December 31, 2016, the Bond, Income and Low Duration Funds recognized a reduction of interest income and a corresponding decrease of net realized loss of $5,803, $1,027 and $2,014, respectively (in thousands). This reclassification had no effect on the net asset value or the net assets of the Funds.

 

December 31, 2016 William Blair Funds 131
 

The Funds do not isolate the portion of operations resulting from fluctuations in foreign currency exchange rates on investments from the fluctuations arising from changes in the value of securities held. Such currency fluctuations are included with the net realized and unrealized gain or loss from investments.

 

Reported net realized foreign currency gains or losses arise from disposition of foreign currency, the difference in the foreign exchange rates between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the ex-date or accrual date and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes (due to the changes in the exchange rate) in the value of foreign currency and other assets and liabilities denominated in foreign currencies held at year end.

 

Security and shareholder transactions are accounted for no later than one business day following the trade date. However, for financial reporting purposes, security and shareholder transactions are accounted for on the trade date of the last business day of the reporting period. Realized gains and losses from securities transactions are recognized on a specifically identified cost basis.

 

Awards from class action litigation may be recorded as a reduction of cost. If the Funds no longer own the applicable securities, the proceeds are recorded as realized gains.

 

(b) Share Valuation and Distributions to Shareholders

 

Shares are sold and redeemed on a continuous basis at net asset value. The net asset value per share is determined separately for each class by dividing the Fund’s net assets attributable to that class by the number of shares of the class outstanding as of the close of regular trading on the New York Stock Exchange (the “NYSE”), which is generally 4:00 p.m. Eastern time, on each day the NYSE is open.

 

Distributions from net investment income, if any, for all Equity and Multi-Asset and Alternative Funds are declared and paid at least annually. Distributions from net investment income for the Bond, Income and Low Duration Funds are declared daily and paid monthly. Capital gain distributions, if any, for all Funds, are declared and paid at least annually in December. Distributions payable to shareholders are recorded on the ex-dividend date.

 

(c) Foreign Currency Translation

 

The Funds may invest in securities denominated in foreign currencies. As such, assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts at the current exchange rate on the date of valuation. The values of foreign investments, open forward foreign currency contracts, and cash denominated in foreign currencies are translated into U.S. dollars using a spot market rate of exchange as of the time of the determination of each Fund’s Net Asset Value, typically 4:00 p.m. Eastern time on days when there is regular trading on the NYSE. Payables and receivables for securities transactions, dividends, interest income and tax reclaims are translated into U.S. dollars using a spot market rate of exchange as of 4:00 p.m. Eastern time. Settlement of purchases and sales and dividend and interest receipts are translated into U.S. dollars using a spot market rate of exchange as of 11:00 a.m. Eastern time.

 

(d) Income Taxes

 

Each Fund intends to comply with the provisions of Subchapter M of the Internal Revenue Code, as amended (the “Code”) available to regulated investment companies. Each Fund intends to make the requisite distributions of income and capital gains to its shareholders sufficient to relieve it from all, or substantially all, federal income and excise taxes. No provision for federal income and excise taxes has been made.

 

Certain Funds may be subject to foreign income taxes imposed on realized gains on securities of issuers from certain foreign countries. Such taxes, if applicable, are included within net realized gain (loss) on transactions from investments in securities on the Statement of Operations.

 

Management has evaluated all of the uncertain tax positions of the Funds and has determined that no liability is required to be recorded in the financial statements.

 

The statute of limitations on the Funds’ prior three years tax returns remain open and the returns are subject to examination.

 

132 Annual Report December 31, 2016
 

Adjustments to the cost of investments for tax purposes are due to the deferred loss associated with current and prior year wash sales, income recognition from investments in real estate investment trusts and partnerships, and the Funds’ election to mark-to-market their investments in Passive Foreign Investment Companies (“PFICs”). The cost of investments for federal income tax purposes and related gross unrealized appreciation (depreciation) and net unrealized appreciation/(depreciation) at December 31, 2016, were as follows (in thousands):

In addition, the Funds may periodically record reclassifications among certain capital accounts to reflect differences between financial reporting and income tax basis distributions. The reclassifications were reported in order to reflect the tax treatment for certain permanent differences that exist between income tax regulations and U.S. generally accepted accounting principles. The reclassifications generally relate to the tax treatment of net operating losses, Section 988 currency gains and losses, PFIC gains and losses, expiration of capital loss carryforward, paydown gains and losses, investments in real estate investment trusts and partnerships, redemptions in-kind, distribution reclassifications, income on derivatives, capital gain taxes, and utilization of earnings and profits distributed to shareholders on redemption of shares. These reclassifications have no impact on the net asset values of the Funds. Accordingly, at December 31, 2016, the following reclassifications were recorded (in thousands):

The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal income tax regulations that may differ from U.S. generally accepted accounting principles. As a result, net investment income or loss and net realized gain or loss for a reporting period may differ from the amount distributed during such period.

 

Distributions from net realized gains for book purposes may include short-term capital gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during 2016 and 2015 was as follows (in thousands):

As of December 31, 2016, the Funds may have unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any. Under current law, the Funds may carry forward net capital losses indefinitely to use to offset capital gains realized in future years. Previous law limited the carry forward of capital losses to the eight tax years following the year the capital loss was realized. If a Fund has capital losses that are subject to current law and also has capital losses subject to prior law, the losses realized under current law will be utilized to offset capital gains before any of the losses governed by prior law can be used. As a result of these ordering rules, capital losses realized under previous law may be more likely to expire unused. Capital losses realized under current law will carry forward retaining their classification as long-term or short-term losses; as compared to under prior law in which all capital losses were carried forward as short term capital losses.

 

The following table details the Funds’ available capital loss carryforwards as of December 31, 2016, the capital loss carryforwards utilized by the Funds in 2016, and the capital loss carryforwards that expired in 2016 (in thousands):

In order to meet certain excise tax distribution requirements, the Funds 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, the Funds are permitted for tax purposes to defer into their next fiscal year qualified late year losses. Qualified late year capital losses are any short term or long term capital losses incurred between November 1 and the end of their fiscal year, December 31, 2016. Qualified late year ordinary losses are comprised of losses related to foreign currency and PFICs incurred between November 1 and the end of their fiscal year, December 31, 2016.

(e) Repurchase Agreements

 

In a repurchase agreement, a Fund buys a security at one price and at the time of sale, the seller agrees to repurchase the security at a mutually agreed upon time and price (usually within seven days). The repurchase agreement thereby determines the yield during the purchaser’s holding period, while the seller’s obligation to repurchase is secured by the value of the underlying collateral. The Adviser monitors, on an ongoing basis, the value of the underlying collateral to ensure that the value always equals or exceeds the repurchase price plus accrued interest. Repurchase agreements may involve certain risks in the event of a default or insolvency of the other party to the agreement, including possible delays or restrictions upon a Fund’s ability to dispose of the underlying collateral. The risk to a Fund is limited to the ability of the seller to pay the agreed upon sum on the delivery date. In the event of default, a repurchase agreement provides that a Fund is entitled to sell the underlying collateral. The loss, if any, to a Fund will be the difference between the proceeds from the sale and the repurchase price. However, if bankruptcy proceedings are commenced with respect to the seller of the security, disposition of the collateral by the Fund may be delayed or limited. The Funds have master repurchase agreements which allow the Funds to offset amounts owed to a counterparty with amounts owed from the same counterparty, including any collateral, in the event the counterparty defaults. As of December 31, 2016, each Fund’s outstanding repurchase agreements, if any, and related collateral, are shown on the Fund’s Portfolio of Investments. Although no definitive creditworthiness criteria are used, the Adviser reviews the creditworthiness of the banks and non-bank dealers with which a Fund enters into repurchase agreements to evaluate those risks. A Fund may, for tax purposes, deem repurchase agreements collateralized by U.S. Government securities to be investments in U.S. Government securities.

 

(f) TBA Securities

 

The Fixed Income Funds may invest in mortgage pass-through securities eligible to be sold in the “to-be announced” market (“TBAs”). TBAs provide for the forward or delayed delivery of the underlying instrument with settlement up to 180 days. The term TBA comes from the fact that the specific mortgage-backed security that will be delivered to fulfill a TBA trade is not designated at the time the trade is made, but rather is generally announced 48 hours before the settlement date. When a Fund sells TBAs, it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold the securities. A Fund generally has the ability to close out a TBA obligation on or before the settlement date, rather than take delivery of the security.

 

(g) Securities Sold, Not Yet Purchased

 

A Fund may sell a security it does not own in anticipation of a decline in the fair value of that security. When a fund sells a security short, it must borrow the security sold short and deliver it to the broker through which it made the short sale. A gain, limited to the price at which the fund sold the security short, or a loss, unlimited in size, will be recognized upon the termination of the short sale. A fund is also subject to the risk that it may be unable to reacquire a security to terminate a short position except at a price substantially in excess of the price it sold the security short.

 

(h) Use of Estimates

 

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from those estimates.

 

(i) Indemnification

 

In the normal course of business, the Funds have entered into contracts in which the Funds agree to indemnify the other party or parties against various potential costs or liabilities. The Funds’ maximum exposure under these arrangements is unknown. No claim has been made for indemnification pursuant to any such agreement of the Funds.

 

(j) Redemption In-Kind

 

In accordance with the Trust’s prospectus, the Funds may distribute portfolio securities rather than cash as payment for a redemption of fund shares (in-kind redemption). For financial reporting purposes, the Fund recognizes a gain or loss on the transfer of securities depending on the value of those securities on the date of redemption. Gains and losses realized on in-kind redemptions may not be recognized for tax purposes and are reclassified from accumulated net realized gain (loss) to capital paid in excess of par value. During the year ended December 31, 2016, the Small-Mid Cap Growth and Institutional International Growth Funds redeemed in-kind fund share redemptions of $159,125 and $210,330 (in thousands), respectively, with securities rather than cash and recognized net realized gains of $52,031 and $23,687 (in thousands), respectively, on the securities distributed to shareholders.

(3) Valuation

 

(a) Investment Valuation

 

The value of domestic equity securities, including exchange-traded funds, is determined by valuing securities traded on national securities markets or in the over-the-counter markets at the last sale price or, if applicable, the official closing price or, in the absence of a recent sale on the date of determination, at the mean between the last reported bid and ask prices.

 

The value of foreign equity securities is generally determined based upon the last sale price on the foreign exchange or market on which it is primarily traded and in the currency of that market as of the close of the appropriate exchange or, if there have been no sales during that day, at the mean between the last reported bid and ask prices. The Board of Trustees has determined that the passage of time between when the foreign exchanges or markets close and when the Funds compute their net asset values could cause the value of foreign equity securities to no longer be representative or accurate and, as a result, may necessitate that such securities be fair valued. Accordingly, for foreign equity securities, the Funds may use an independent pricing service to fair value price the security as of the close of regular trading on the NYSE. As a result, a Fund’s value for a security may be different from the last sale price (or the mean between the last reported bid and ask prices). As of December 31, 2016, fair valuation estimates for foreign equity securities were not obtained.

 

Fixed income securities are generally valued using evaluated prices provided by an independent pricing service. The evaluated prices are formed using various market inputs that the pricing service believes accurately represent the market value of a security at a particular point in time. The pricing service determines evaluated prices for fixed income securities using inputs including, but not limited to, recent transaction prices, dealer quotes, transaction prices for securities with similar characteristics, collateral characteristics, credit quality, payment history, liquidity and market conditions.

 

Repurchase agreements are valued at cost, which approximates fair value.

 

Option contracts on securities, currencies and other financial instruments traded on one or more exchanges are valued at their most recent sale price on the exchange on which they are traded most extensively. Option contracts on foreign indices are valued at the settlement price. Futures contracts (and options and swaps thereon) are valued at the most recent settlement price on the exchange on which they are traded most extensively. Forward foreign currency contracts are valued on the basis of the value of the underlying currencies at the prevailing currency exchange rate as supplied by an independent pricing service.

 

Over-the-Counter (“OTC”) swap contracts are valued by an independent pricing service. Depending on the product and the terms of the transaction, the independent pricing service may use a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as issuer details, indices, spreads, interest rates, yield curves, dividends and exchange rates.

 

Centrally cleared swaps listed or settled on a multilateral or trade facility platform, such as a registered exchange, are valued at the daily settlement price determined by the respective exchange. For centrally cleared credit default swaps the clearing facility requires its members to provide actionable price levels across complete term structures. These levels along with external third-party prices are used to produce daily settlement prices.

 

Investments in other investment funds that are not exchange-traded funds are valued at the underlying fund’s ending net asset value on the date of valuation.

 

Securities, and other assets, for which a market price is not available or is deemed unreliable (e.g., securities affected by unusual or extraordinary events, such as natural disasters or securities affected by market or economic events, such as bankruptcy filings), or the value of which is affected by a significant valuation event, are valued at a fair value as determined in good faith by, or under the direction of, the Board of Trustees and in accordance with the Valuation Procedures approved by the Board of Trustees. The value of fair valued securities may be different from the last sale price (or the mean between the last reported bid and ask prices), and there is no guarantee that a fair valued security will be sold at the price at which a Fund is carrying the security.

 

As of December 31, 2016, there were securities held in the International Growth and Institutional International Growth Funds requiring fair valuation pursuant to the Valuation Procedures approved by the Board of Trustees.

 

(b) Fair Value Measurements

 

Fair value is defined as the price that a Fund would receive upon selling a security in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. Various inputs are used in determining the value of a Fund’s investments. A three-tier hierarchy of inputs is used to classify fair value measurements for disclosure purposes. The three-tier hierarchy of inputs is summarized in the three broad levels listed below:

 

138 Annual Report December 31, 2016
 
  Level 1—Quoted prices (unadjusted) in active markets for an identical security.
     
  Level 2—Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others. In addition, other observable inputs such as foreign exchange rates, benchmark securities indices and foreign futures contracts may be utilized in the valuation of certain foreign securities when significant events occur between the last sale on the foreign securities exchange and the time at which the net asset value of the Fund is calculated.
     
  Level 3—Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in pricing an investment, and would be based on the best information available.

 

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

 

A description of the valuation technique applied to the Funds’ major categories of assets and liabilities measured at fair value on a recurring basis as follows:

 

Exchange-Traded Securities

 

Securities traded on a national securities exchange (or reported on the NASDAQ national market), including exchange-traded funds, are stated at the last reported sales price on the day of valuation. Other securities traded in the over-the-counter market and listed securities for which no sale was reported on that date are stated at the mean between the last reported bid and ask prices. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy. Securities traded on inactive markets or valued by reference to similar instruments are generally categorized as Level 2 of the fair value hierarchy.

 

Fixed Income Securities

 

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, convertible preferred securities, asset-backed securities and non-U.S. bonds are generally valued using evaluated prices provided by an independent pricing service. The evaluated prices are formed using various market inputs that the pricing service believes accurately represent the fair value of a security at a particular point in time. The pricing service determines evaluated prices for fixed income securities using inputs including, but not limited to, recent transaction prices, dealer quotes, transaction prices for securities with similar characteristics, collateral characteristics, credit quality, payment history, liquidity and market conditions. Securities that use similar valuation techniques and observable inputs as described above are categorized as Level 2 of the fair value hierarchy.

 

Short-Term Investments

 

Repurchase agreements are valued at cost, which approximates fair value. These investments are categorized as Level 2 of the fair value hierarchy.

 

Derivative Instruments

 

Listed derivatives, such as certain options and futures contracts, that are actively traded are valued based on quoted prices from the exchange on which they are traded most extensively and are categorized as Level 1 of the fair value hierarchy. OTC derivative contracts include forward foreign currency contracts, swap and certain option contracts related to interest rates, foreign currencies, credit standing of reference entities, equity prices, or commodity prices. Depending on the product and the terms of the transaction, the fair value of OTC derivative products can be modeled taking into account the counterparties’ creditworthiness and using a series of techniques, including simulation models. Many pricing models do not entail material subjectivity because the methodologies employed do not necessitate significant judgments and the pricing inputs are observed from actively quoted markets, as is the case of forward foreign currency contracts and interest rate swaps. A substantial majority of OTC derivative products valued by a Fund using pricing models fall into this category and are categorized as Level 2 of the fair value hierarchy.

 

Any transfers between Level 1 and Level 2 are disclosed, effective as of the beginning of the period, in the following tables with the reasons for the transfers disclosed in a note to the tables, if applicable. Transfer amounts are based on end of period values.

Level 1 Common Stocks are exchange-traded securities with a quoted price. See Portfolio of Investments for Sector Classification.

 

The fair value estimates for the Level 3 securities in the International Growth and Institutional International Growth Funds were determined in good faith by the Pricing Committee, pursuant to the Valuation Procedures approved by the Board of Trustees. There were various factors considered in reaching this fair value determination, including, but not limited to, the following: the type of security, the extent of public trading of the security, information obtained from a broker-dealer for the security, analysis of the company’s performance and market trends that influence its performance. Level 3 securities represented 0.00% and 0.00% as a percentage of net assets in the International Growth and Institutional International Growth Funds, respectively. The change in net unrealized gain (loss) related to those securities held at December 31, 2016 is included in the change in net unrealized appreciation (depreciation) of investments on the Statements of Operations.

(b) Underwriting, Distribution Services, and Shareholder Administration Agreements

 

Pursuant to separate Underwriting and Distribution Agreements, WBC is the principal underwriter and distributor for the continuous offering of shares of the Trust and acts as agent of the Trust in the sale of its shares. The Underwriting Agreement provides that the Distributor will use its best efforts to distribute the Trust’s shares. The Distributor is not compensated under the Underwriting Agreement.

 

Each Fund, except the Institutional International Equity Fund and Institutional International Growth Fund, has a Distribution Agreement with WBC for distribution services to the Funds’ Class N shares. Each Fund pays WBC an annual fee, payable monthly, based on a specified percentage of its average daily net assets of Class N shares. The annual rate expressed as a percentage of average daily net assets for Class N is 0.25% for all Funds except the Bond, Income and Low Duration Funds, which is 0.15%. Pursuant to the Distribution Agreement, WBC enters into related selling group agreements with various firms at various rates for sales of the Funds’ Class N shares.

 

The Global Leaders, International Leaders, International Small Cap Growth, Emerging Markets Leaders, Emerging Markets Growth, Emerging Markets Small Cap Growth, Bond, Low Duration and Macro Allocation Funds have a Shareholder Administration Agreement with WBC to provide shareholder administration services to Class N and Class I shares. Class N and Class I shares of the Funds have agreed to pay an annual fee, payable monthly, of 0.15% of average daily net assets attributable to each class, respectively. Beginning in 2013, the SEC conducted a limited scope examination of a number of mutual fund sponsors, including WBC, regarding distribution and servicing of mutual fund shares through intermediaries. In November 2014, the SEC informed WBC that it had opened a non-public investigation with respect to shareholder administration fees paid by the applicable Funds. The investigation does not involve the investment management operations of the Funds. In December 2015, the SEC staff sent WBC a notification that staff intended to recommend an enforcement action against WBC to the SEC Commissioners (Wells Notice), and WBC has submitted a response. At this time, it is unclear whether or not the Commission will allow the matter to enter enforcement proceedings. While WBC believes that any possible claims made by the staff would be without merit, WBC cannot predict the outcome of any enforcement proceeding the SEC may choose to bring. The shareholder administration fee for each Fund is currently being waived by WBC. This waiver will not be removed without approval of the Board of Trustees.

(6) Financial Derivative Instruments

 

Each Fund may use derivative instruments to maintain liquidity, to provide hedging, or in anticipation of changes in the composition of its portfolio holdings or as otherwise provided in each Fund’s prospectus. Macro Allocation Fund may also use derivative instruments to obtain investment exposures. The derivative instruments held as of December 31, 2016, as disclosed in each Fund’s Portfolios of Investments, are representative of each Fund’s derivative instrument trading activity during the year ended December 31, 2016.

 

Derivative transactions carry counterparty risk as they are based on contracts between a Fund and the applicable counterparty. For exchange-traded or cleared derivative contracts, such counterparty risk is limited due to the role of the exchange or clearinghouse. OTC derivative contracts, however, are exposed to counterparty risk in the amount of unrealized gains, net of collateral held, for the duration of the contract.

 

Macro Allocation Fund is subject to certain netting arrangements through International Swaps and Derivatives Association, Inc. Master Agreements and Credit Support Annexes (“ISDAs”). The ISDAs maintain provisions for general obligations, representations, agreements, collateral and events of default or termination. The ISDAs cover certain OTC derivative securities entered into by Macro Allocation Fund with various counterparties and allow Macro Allocation Fund to close out and net its total exposure to a counterparty in the event of a default.

 

Futures Contracts

 

A futures contract provides for the future sale by one party and purchase by another party of a specified amount of a specific financial instrument for a specified price at a designated date, time and place. An index futures contract is an agreement pursuant to which the parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index futures contract was originally written. If the offsetting purchase price is less than the original sale price, a Fund realizes a gain; if it is more, a Fund realizes a loss. Conversely, if the offsetting sale price is more than the original purchase price, a Fund realizes a gain; if it is less, a Fund realizes a loss. The transaction costs must also be included in these calculations. There can be no assurance, however, that a Fund will be able to enter into an offsetting transaction with respect to a particular futures contract at a particular time. If a Fund is not able to enter into an offsetting transaction, a Fund will continue to be required to maintain the margin deposits on the futures contract.

 

Upon entering into a futures contract, a Fund is required to pledge to the broker an amount of cash, U.S. government securities, or other liquid assets equal to a certain percentage of the contract amount (“initial margin deposit”). Futures contracts are marked to market daily and an appropriate payable or receivable for the change in value (“variation margin”) is recorded by a Fund and a cash payment is either made to or received from the broker. Futures held through swaps are marked to market daily, however, a Fund does not make or receive cash payments to/from the broker. Gains or losses are recognized but not considered realized until the contracts expire or are closed and are included in the Statement of Operations.

 

Options

 

The purchase or sale of an option by a Fund involves the payment or receipt of a premium by the investor and the corresponding right or obligation, as the case may be, either to purchase or sell the underlying security, commodity, or other instrument for a specific price at a certain time or during a certain period. Purchasing options involves the risk that the underlying instrument will not change price in the manner expected, so the investor loses its premium. Writing options involves potentially greater risk because the investor is exposed to the extent of the actual price movement in the underlying security rather than only the amount of the premium paid (which could result in a potentially unlimited loss). OTC options also involve counterparty credit risk. Purchased options are shown as an asset on the Statement of Assets and Liabilities and are included in Investments in securities. Premiums received for written options are shown as a liability on the Statement of Assets and Liabilities. Realized gains and losses on the sale, expiration or assignment of an option are disclosed on the Statement of Operations.

Forward Foreign Currency Contracts

 

The Global Equity, International Equity and Multi-Asset and Alternative Funds may enter into forward foreign currency contracts. When entering into a forward foreign currency contract, a Fund agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. A Fund’s net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statement of Assets and Liabilities. Realized and unrealized gains and losses are included in the Statement of Operations. These instruments may involve market risk, credit risk, or both kinds of risks in excess of the amount recognized in the Statement of Assets and Liabilities. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from the price movements in currencies.

 

Swap Contracts

 

Swap agreements may include total return, interest rate, securities index, commodity, security, currency exchange rate, credit default index, volatility and variance swaps. Swap agreements typically are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to several years. Cleared swaps are transacted through futures commission merchants that are members of central clearing houses with the clearing house serving as a central counterparty similar to transactions in futures contracts. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount” (i.e., the change in the value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index). Swap agreements are subject to the risk that the counterparty to the swap will default on its obligation to pay a Fund and the risk that a Fund will not be able to meet its obligations to pay the counterparty to the swap. Swap agreements may also involve fees, commissions or other costs that may reduce a Fund’s gains from a swap agreement or may cause a Fund to lose money. To the extent permitted by its investment policies and restrictions, a Fund may invest in the following types of swaps:

 

Credit Default Swaps—A Fund may invest in credit default swaps as a means of “buying” credit protection (i.e., attempting to mitigate the risk of default or credit quality deterioration in some portion of a Fund’s holdings) or “selling” credit protection (i.e., attempting to gain exposure to an underlying issuer’s credit quality characteristics without directly investing in that issuer). A credit default swap is a contract between a buyer and a seller of protection against a pre-defined credit event (e.g., a ratings downgrade or default) on an underlying reference obligation, which may be a single debt instrument or baskets or indices of securities. A Fund may be a buyer or seller of a credit default swap. As a seller of protection on credit default swap agreements, a Fund will generally receive from the buyer of protection a fixed rate of income throughout the term of the swap provided that there is no credit event. A Fund adds leverage to its portfolio because the Fund is subject to investment exposure on the notional amount of the swap. The maximum potential amount of future payments that a Fund as a seller of protection could be required to make under a credit default swap agreement equals the notional amount of the agreement. Notional amounts of each individual credit default swap agreement outstanding as of period end for which a Fund is the seller of protection are disclosed in Portfolio of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by a Fund for the same referenced entity or entities. For credit default swap contracts on credit indices, the quoted market prices and resulting values serve as an indicator of the payment performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent deterioration of the referenced entities’ credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the swap.

 

Interest Rate Swap—A Fund may invest in interest rate swaps to gain or mitigate exposure to changes in interest rates. Interest rate swap agreements involve a commitment between parties to pay either a fixed interest rate or a floating interest rate based on a notional amount of principal. The parties make payments at predetermined intervals throughout the life of the swap. As a payer, a Fund would make the fixed payment and receive the floating payment. As a receiver, a Fund would make the floating payment and receive the fixed payment.

 

Total Return Swap—A Fund may invest in total return swaps to gain or mitigate exposure to an underlying security, or securities. Total return swap agreements may involve commitments to pay interest in exchange for the return on the underlying security, or securities. At maturity, a net cash flow is exchanged between the parties based on the total return of the underlying security, or securities, less a financing rate. As a receiver, a Fund would receive a payment for a positive return and would make a payment for a negative return. As a payer, a Fund would make a payment for a positive return and would receive a payment for a negative return.

Variance Swap—A Fund may invest in variance swaps in order to gain or mitigate its exposure to an underlying reference entity such as a broad based index. A variance swap is an agreement between two parties to exchange cash flows based on the measured variance of a reference entity. The payer agrees to exchange the fixed rate, or the variance strike price of the reference entity, to the receiver for the floating rate, or realized variance price of the reference entity. At the time the trade is originated, the agreed upon variance strike price is generally set so that the fair value of the swap is near zero. At maturity, a net cash flow is exchanged between the parties based on the difference between the final realized variance price of the swap and the variance strike price multiplied by the notional, or vega amount. As a receiver of the floating rate, a Fund would receive a payment if the final realized variance price is greater than the variance strike price and would make a payment if the final realized variance price is less than the variance strike price. As a payer of the floating rate, a Fund would receive a payment if the final realized variance price is less than the variance strike price and would make a payment if the final realized variance price is greater than the variance strike price.

184 Annual Report December 31, 2016
 

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 

To the Board of Trustees and Shareholders of William Blair Funds

 

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of the William Blair Funds (comprising, respectively, the Growth Fund, Large Cap Growth Fund, Mid Cap Growth Fund, Mid Cap Value Fund, Small-Mid Cap Growth Fund, Small-Mid Cap Value Fund, Small Cap Growth Fund, Small Cap Value Fund, Global Leaders Fund, International Leaders Fund, International Equity Fund, Institutional International Equity Fund, International Growth Fund, Institutional International Growth Fund, International Small Cap Growth Fund, Emerging Markets Leaders Fund, Emerging Markets Growth Fund, Emerging Markets Small Cap Growth Fund, Bond Fund, Income Fund, Low Duration Fund, and Macro Allocation Fund (collectively, the “Funds”)) as of December 31, 2016, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for the periods indicated therein. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

 

We conducted our audits 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Funds’ internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.

(1) Each Trustee serves until the election and qualification of a successor, or until death, resignation or retirement, or removal as provided in the Trust’s Declaration of Trust. Retirement for Non-Interested Trustees occurs no later than at the conclusion of the first regularly scheduled Board meeting of the calendar year that occurs after the earlier of (a) the Non-Interested Trustee’s 72nd birthday or (b) the 15th anniversary of the date that the Non-Interested Trustee became a member of the Board of Trustees. The Board of Trustees approved an exception to this retirement policy to defer the retirement of Mr. Seeley and Mr. Peterson until February 2018.
(2) Mr. Avedisian served as a member of the Board of Directors of Potbelly Corporation (“Potbelly”) from 2001 to 2015. In October 2013, Potbelly completed an underwritten initial public offering of its common stock (the “Offering”). William Blair served as a member of the underwriting syndicate. At the time of the Offering, Mr. Avedisian, through entities he owns or controls, indirectly beneficially owned 1,607,448 shares of Potbelly common stock and warrants to purchase 241,704 shares of common stock representing approximately 8.9% of the shares before the Offering. Mr. Avedisian disclaimed beneficial ownership of the shares except to the extent of his pecuniary interest therein. Potbelly sold 8,474,869 shares and certain stockholders, including two entities affiliated with William Blair, sold 150,131 shares in the Offering at a price to the public of $14.00 per share. Neither Mr. Avedisian nor the entities he owns or controls was a selling stockholder in the Offering. A portion of the net proceeds received by Potbelly from the Offering was used to pay a previously declared cash dividend, in an aggregate amount of approximately $49.9 million, on Potbelly common and preferred shares outstanding immediately prior to the closing of the Offering, which included the outstanding shares indirectly beneficially owned by Mr. Avedisian, William Blair and the two entities affiliated with William Blair.

190 Annual Report December 31, 2016
 

Useful Information About Your Report (Unaudited)

 

Please refer to this information when reviewing the Expense Example for each Fund.

 

Expense Example

 

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees, distribution (12b-1) fees (for Class N shares except for the Institutional International Growth Fund and the Institutional International Equity Fund), shareholder administration fees (for Class N and Class I shares of the Global Leaders Fund, the International Leaders Fund, the International Small Cap Growth Fund, the Emerging Markets Leaders Fund, the Emerging Markets Growth Fund, the Emerging Markets Small Cap Growth Fund, the Bond Fund, the Low Duration Fund and the Macro Allocation Fund) and other Fund expenses. The 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. To do so, compare the Fund’s 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from July 1, 2016 to December 31, 2016.

 

Actual Expenses

 

In each example, the first line for each share class in the table provides information about the actual account values and actual expenses. These expenses reflect the effect of any expense cap applicable to the share class during the period. Without this expense cap, the costs shown in the table would have been higher. 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 (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 the Period” to estimate the expenses you paid on your account during the period.

 

Hypothetical Example for Comparison Purposes

 

In each example, the second line for each share class in the table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. This 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 to other funds. To do so, compare 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 both examples are meant to highlight your ongoing costs only and do not reflect any transactional costs or account type fees, such as IRA administration fees. These fees are fully described in the prospectus. Therefore, the second line of each share class in the table is useful in comparing ongoing costs only and will not help you determine the relative costs of owning different funds. In addition, if these transactional costs or account fees were included, your costs would have been higher.

Item 2. Code of Ethics

 

As of the end of the period covered by this Form N-CSR, the Registrant has adopted a code of ethics that applies to its principal executive officer and principal financial officer. Such code of ethics is posted on the Registrant’s website: www.williamblairfunds.com. There were no amendments to or waivers of the code of ethics during the period covered by this report. 

 

Item 3. Audit Committee Financial Expert

 

The Registrant’s Board of Trustees has determined that the Registrant has at least one “audit committee financial expert” (as defined in Item 3 of Form N-CSR) serving on its Audit Committee. Mr. Phillip O. Peterson, the Registrant’s audit committee financial expert, is “independent” for purposes of Item 3 to Form N-CSR.

 

An “audit committee financial expert” is not an “expert” for any purpose, including for purposes of Section 11 of the Securities Act of 1933, as a result of being designated as an “audit committee financial expert.” Further, the designation of a person as an “audit committee financial expert” does not mean that the person has any greater duties, obligations, or liability than those imposed on the person without the “audit committee financial expert” designation. Similarly, the designation of a person as an “audit committee financial expert” does not affect the duties, obligations, or liability of any other member of the audit committee or Board of Trustees.

Pursuant to the Charter, the Audit Committee is also responsible for pre-approving any engagement of the principal accountant, including the fees and other compensation to be paid to the principal accountant, to provide non-audit services to the Registrant’s investment advisor (or any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the Registrant), if the engagement relates directly to the operations and financial reporting of the Registrant, to the extent required by Rule 2-01(c)(7) of Regulation S-X. The Chair of the Audit Committee may grant the pre-approval referenced above for non-prohibited and non-audit services.
