Thank you, Jason, and good morning, everyone. Since our operating data is already known, I'll quickly go through the important items for the quarter, discuss our outlook for 2019, and then return the call over to Jono for some closing remarks before we open it up to Q&A.
So beginning on Slide 3. Despite market headwinds, we demonstrated positive organic growth during the quarter. Our global AUM was $54 billion at the end of the year. However, with net inflows and the market rebound in January, current AUM is over $58 billion, recovering much of the fourth quarter decline. Like all asset managers had this quarter, we experienced negative market movement of over $5 billion. Continued political and economic uncertainty in Europe, growth concerns in Japan and a broader risk loss sentiment drove further outflows from HEDJ and DXJ. However, as this chart in the middle reflects, the rest of our franchise exhibited solid and diversified growth. We saw the benefits of our April acquisition of ETF Securities as commodity flows were strongest amidst the global equity market sell off. And we also saw robust demand for our fixed income ETFs, where momentum continues to build. And as you can see in the chart on the right, our geographical diversification efforts are paying off, with inflows in Europe and Canada more than offsetting the DXJ and HEDJ-driven U.S. outflows.
Digging a little deeper into our U.S. segment flow highlights on Slide 4. We continue to see the breadth of -- the benefits of flow breadth and depth from our strategic initiatives around Advisor Solutions, investments in technology and new distribution channels and partnerships. The number of funds with creations on a daily basis remains above historical levels, and the percentage of our assets in core funds continues to grow, generating inflows for the 13th straight quarter.
At the fund level, we saw positive demand in our floating rate treasury fund, USFR, which generated inflows of $790 million in the quarter, with growth continuing into 2019. USFR has grown from just under $1 million at the start of 2018 to $2 billion today, reflecting client demand due to rising short-term rates, a flattening yield curve and increased volatility of riskier assets. Despite the substantial equity market selloff, our domestic equity and emerging market equity funds generated solid inflows, with domestic equities recording the strongest flow quarter in 2 years led by our large cash strategies, DGRW and DLN. While AUM was pressured due to market volatility, flows into our core funds were positive for the 13th straight quarter, totaling $1.2 billion in the fourth quarter, the best results in at least 4 years.
Now let's take a closer look at our international segment flows on Slide 5. The gold star this quarter goes to our international segment, which generated inflows led by our gold products, as commodity shifted into favor and the funds we acquired from ETF Securities exhibited market leadership. Gold inflows totaled $667 million across the complex, representing 27% market share of Europe-listed gold flows compared to our AUM market share of 25%. We also had positive flows into our oil ETPs as the price of oil fell. Our usage had inflows of $223 million, also driven by demand for our broad-based commodity EPS. Our Canadian-listed products generated inflows of $85 million, driven by the launch of our core+ bond fund and flows into our quality dividend growth EPS. For the year, we generated over $300 million of Canada-listed EPS flows.
Now let's turn to the financial results on Slide 6. Revenues were just under $68 million for the quarter, reflecting lower average AUM due to the significant pressure on global asset prices as all asset managers experienced. On a GAAP basis, we had a net loss of $12 million, which included several nonoperating charges. First, the increase in the price of gold led to an after-tax noncash charge of $5.4 million for our future gold commitment payments. Second, we wrote off the accounting value of the option we have to purchase the rest of AdvisorEngine as we let the option expire. In the context of the challenging market backdrop at the end of the year, we didn't feel it was prudent to exercise the option at this time, but we remain their largest shareholder. We have a great relationship with AdvisorEngine and are excited about our growth prospects with them.
We also wrote down the carrying value of our intangible asset in GCC and ownership in Pieces Technologies. We also incurred $1.5 million of severance and other charges as part of our previously announced cost-reduction initiatives. And finally, we incurred $800,000 of acquisition-related costs. Adjusting for these items, we are in $10 million or $0.06 a share in the quarter. The adjusted tax rate in the quarter was 23%. As we look forward, we still expect a blended tax rate of roughly 26% to 27%. The lower rate in the fourth quarter reflected the benefit of tax windfalls from the exercise of low price stock options. Please see the appendix of this presentation, where we disclosed additional information on the tax effect of stock-based compensation on our projected tax expense in the first quarter.
Turning to the U.S. segment on the next slide. Gross margins were 80.2%, down sequentially, reflecting lower average U.S.-listed AUM in the quarter, negative mix shift, recent product launches and some seasonal charges associated with the annual rebalances of our EPS. Adjusted operating margins for the U.S. segment were 23.7%, reflecting the lower revenue and gross margin. Total U.S. segment expenses, excluding acquisition and severance-related costs, increased 4% sequentially to $34.9 million, primarily by higher marketing and sales expenses, which typically pick up in the fourth quarter. The compensation ratio for the full year was 27.4%, the low end of the 27% to 29% guidance range after adjusting for the severance costs.
Turning to Slide 8. Let's take a look at the financial results of our international segment. Gross margins were 69.1%, down sequentially, reflecting the higher costs due to timing of certain expenses. Adjusted operating margins for this segment were 18%, reflecting the decline in gross margins and modest growth in discretionary spending. Total international segment expenses, excluding acquisition-related costs, increased 7% sequentially to $18.1 million, as we [ continue to experience ] the scale benefits of the ETF Securities transaction and invest for accelerated growth in the region.
Now let's turn to our 2019 expense outlook on Slide 9. We are updating some of the guidance metrics. First, beginning with compensation. Previously, we guided this line item as a percent of revenue. However, as we have experienced volatility in our flows and revenues can lead to this line item being very difficult to model. To allow you to better model this expense going forward, we are disclosing a dollar range that reflects the minimum levels of compensation to run our business at a high end if we meet certain internal targets. We expect compensation expense in the U.S. to range between $53 million and $63 million, and $17 million to $19 million for our non-U.S. business. There could be upside to this -- high end of this range if our results exceed our internal targets. We will give you updated guidance if we believe we are trending towards that. Based on our current AUM and asset mix, we expect gross margins for our U.S. business to be between 80% and 81%, and 70% to 72% for our non-U.S. business. Both of these are near-term guidance numbers, and we'll update these if we experience a change.
You have heard us talk about the benefits of entering into preferred or exclusive relationships with third-party platforms. As we continue to build out these relationships, we expect that line item to be approximately 3.5% of revenues in the U.S.
Given the market backdrop, we are holding all of our other expenses flat to annualized second half numbers, which already take into account our previously announced cost-reduction initiatives. Our priority and focus is to make the right investments to grow our business to maximize value to our shareholders, while at the same time, managing our cost base. As our business scales, we will see upside in our margins with operating leverage across compensation, fund costs and discretionary items. We have proven before we can achieve amongst the highest margins, and we can achieve those again. It's all about scaling our AUM.
Now it's my pleasure to turn the call over to Jono.
