Analyst · Jefferies
Thank you, Jason, and good morning, everyone. Most of our operating data is already known, so I'll quickly go through the important items for the quarter, discuss recent flow diversification trends, and provide some guidance on how we're thinking about 2018. I'll then turn the call over to Kurt MacAlpine, our Global Head of Distribution for comments around some key initiatives, before Jono will make some closing remarks and we open the call to Q&A.
Beginning on Slide 3, our U.S. AUM grew to $46.8 billion at the end of the fourth quarter, primarily due to positive market movement. The U.S. dollar's continued decline versus the euro drove significant outflows from HEDJ that largely offset flows in our other ETF categories, as the middle chart shows. The chart on the right reflects our flows x HEDJ and DXJ, which total $1.1 billion for the quarter.
The strongest quarterly result in 5 years and that strength has continued through January.
Turning to the next slide, we can dig into where we are seeing flow strength. During the quarter, we saw a continued strong demand for our U.S. -- for our non-U.S. small cap strategies which had aggregate inflows of $435 million.
Our suite of domestic fixed income ETF had their strongest quarter ever with $179 million of inflows driven by AGGY, which continues to build an impressive performance track record versus passive benchmarks and the most sophisticated active managers.
During the fourth quarter, the dollar/yen was fairly stable and sentiment briefly improved towards Japan. WisdomTree took a $0.94 out of every dollar that went into the currency hedged Japan theme. This illustrates that the flow challenges we had with DXJ and HEDJ are market sentiment driven and when sentiment turns, we lead the flows given our competitive strength in the currency hedge category. This quarter also showed diversified record flows, with 48 different funds generating inflows.
11 of our ETFs, across a broad range of strategies producing greater than $50 million of inflows and 10 funds generating record quarterly inflows.
We believe the momentum and diversification we are now experiencing is a direct result of the investments we've made over the last several quarters around solutions, technology and new distribution channels, which is part of the strategy we laid out a year ago, which I would like to discuss on the next slide.
We have taken active steps to diversify and grow our asset base. This includes investing in new distribution channels, like the relationship we recently announced with TD. Harnessing big data to make our distribution efforts more targeted. Investing in technology initiatives like our digital tool, which helps advisers build portfolios, optimizing WisdomTree ETFs and lastly, building out an adviser solutions program platform to deepen our relationship with advisers.
These initiatives rolled out in the quarter and we have -- and they have one end goal, to increase flows into our ETFs and we are now seeing the results of these actions starting to take form.
As you can see in the top chart on this slide, the net flow breadth has accelerated in the past several months. We are seeing a significant increase in the number of funds with creations on a daily basis. Over the past 2 years on average, we saw 2 to 3 funds create on a daily basis. That has recently increased to nearly 5 funds in the fourth quarter and 8 funds so far in January. In addition, a record 48 U.S. listed ETFs generated net inflows for the quarter, reflecting a combination of core strategic funds as well as more tactical exposures.
These flows have translated into greater AUM in our core strategic funds, which you can see in the chart on the bottom of this slide. These core strategic funds generated more than $4 billion in net inflows over the past 2 years, representing a 15% annualized organic growth rate, including $820 million of inflows during the fourth quarter.
These core strategic funds now make up 52% of our AUM versus 35% 2 years ago. We are very encouraged by these signs of accelerated and diversified flows and will continue to focus our efforts on initiatives that we believe are driving it.
Now turning to our financial results on Page 7.
Revenues increased 19% from the fourth quarter of last year to $61.4 million. Net income was $200,000 for the quarter, or $5.2 million adjusted for 2 unusual items.
During the quarter, we incurred $4.5 million of adviser fees, associated with our announced acquisition of ETF Securities, and our loan and option agreement with AdvisorEngine. We also incurred a $400,000 charge to write-down the value of our deferred tax assets as a result of the new tax reform rules.
The elevated tax rate in the quarter reflected the nondeductibility of the transaction cost and our international segment losses as well as the write-down of our deferred tax asset.
We also had some specific events occur in the fourth quarter which drove up compensation expense.
The first relates to incentive compensation. We typically award incentive compensation in a mix of cash and stock, which vests over 3 years. The cash portion of the incentive compensation is recorded as an expense in the current year and the stock portion is recognized as an expense over the 3-year vesting period.
In the fourth quarter, we made a determination to change the weighting more towards cash, so we would incur less stock-based compensation expense in future periods. This change resulted in a higher expense in the fourth quarter than what we had initially planned, but it also reduced charges in future periods. This change did not result in a higher total bonus to employees, just in how we record the bonus expense.
Second, in the quarter, we increased the incentive compensation pool to recognize the achievement of key milestones involving several important strategic initiatives, as well as the hiring of a key executive. And lastly, because of the tax reform rules, we accelerated the vesting of certain stock awards, originally scheduled to vest in January, in order for the company to maximize the tax deductibility of the award. Now I'd like to turn our thoughts to 2018 guidance on the next slide.
This is the guidance for our existing business and does not include the ETF Securities transaction. Starting with our U.S. Business segment and walking down the expense line items on our income statements, starting with compensation. We expect compensation to be in the range of 27% to 29% of U.S. revenues, which is down from 32% in 2017. For fund operating cost, we give guidance as gross margin. Historically, gross margin included fund operating cost and third-party revenue sharing. Given the success of our relationships with key distribution platforms, like TD and Schwab and our marketing arrangement with the Compass Group, we are no longer including third-party sharing as part of gross margin, since it's really a distribution-related cost. Therefore, gross margins going forward will only include adviser fee revenues, less fund operating cost, so it's more accurate to model.
We expect the revised gross margin to be 84% in the near term. Third-party sharing costs are approximately 2.6% of revenues today, and we expect it to range between 2.6% and 3% of revenues each quarter, depending upon the growth of AUM with our distribution partners.
We will continue to give updated guidance on both gross margin and third-party sharing each quarter. We also expect a nominal increase in other overhead costs. To maintain our competitive position and leadership in the fast-growing ETF industry, it is important to make continued investments in our business to drive long-term growth. We expect to invest $3 million to $5 million this year on strategic growth initiatives, which will focus on expanding our distribution capabilities, specifically around adviser solutions.
Continuing to build our technology initiatives, focused on distribution and adviser-oriented technology through our investment in AdvisorEngine. In addition, we will continue to invest in product and brand awareness as well as launching 6 to 8 new ETFs in 2018. We believe this amount balances the need to make the right focused strategic investments and manage our cost base.
Turning now overseas. Our International segment losses are improving and we expect them to have $7 million to $10 million of losses in 2018.
Again, this is prior to the ETF Securities transaction, which will immediately make our International segment profitable. Our U.S. tax rate will be 28% and 33% on a consolidated basis, because of the nondeductibility of our foreign losses. After the ETF Securities transaction, our consolidated tax rate is expected to be approximately 30%.
Now I'd like to give you an update on the ETF Securities transaction. The integration process is going well and is well on its way and we are proceeding to a close, which is expected sometime at the end of the first quarter.
We will give updated guidance of the business on our next earnings call, but in the meantime, we are on target with our previously announced synergies and their contribution of approximately $19 million of net income in 2018.
Their AUM has increased since we announced the deal and now stands at $18.2 billion.
Now an update on our results so far this quarter. As of yesterday, our U.S. AUM is up to approximately $48 billion driven by continued market strength, while DXJ and HEDJ have waited on net inflows, quarter-to-date we've seen a continuation of the strong flow diversity with nearly $800 million of inflows in January, excluding those 2 funds.
One of the strongest months in the firms' history.
Now I'd like to turn the call over to Kurt MacAlpine, our Global Head of Distribution to discuss several of the key drivers beyond -- behind the improved flow diversity and momentum.
