Thank you, Juan Ramón, and good morning, everyone.
Before I get into the details on our fourth quarter performance and guidance for 2018, I will provide a few comments on the results for full year 2017. This year, we delivered operational revenue growth above the market, grew adjusted net income faster than revenue and almost doubled our operating cash flow. Reported revenue for full year 2017 was $5.3 billion with operational revenue growth of 8%. Of this 8%, 3.5% came from our dermatology portfolio, 3.5% came from Simparica and other new products and the remainder of growth came from price and volume. Our product rationalization initiative had an unfavorable impact of 1% on volume for the year.
Adjusted net income for full year 2017 was $1.2 billion and grew 21% operationally. Adjusted net income continues to grow faster than revenue driven by the continued impact of our operational efficiency initiative and a lower adjusted effective tax rate. Our performance this year, again, reaffirms our ability to execute on the financial targets that we said in May of 2015 when we provided long-term guidance through to 2017.
With the results that we are reporting today, both our top and bottom line in 2017, beat the goal outlined nearly 3 years ago. For the full year, we've performed well across all the species and key markets where we compete. The diversity and durability of our existing portfolio, our market-leading commercial and manufacturing capabilities and the innovations we bring to the marketplace have allowed us to outpace the animal health industry market growth for the last 5 years.
Our income growth and our increased discipline on the balance sheet have enabled us to almost double our operating cash flow in 2017. This was the result of lower cash outlays for termination benefits and stand-up costs, increased profitability and inventory improvements. In 2017, we reduced our months on hand of inventory by more than a month. We have more work to do in this area but are pleased with the progress in 2017.
Turning now to quarterly results. Q4 2017 was an exceptional quarter, with top line growth coming from new products in our companion animal portfolio and strong livestock performance in our U.S. and International businesses. Our product rationalization initiative had no material impact on our growth this quarter and will not have an impact on our revenue growth going forward. Total company revenue in the fourth quarter grew 13% operationally, excluding the favorable 1% impact from foreign exchange. Our key dermatology products, Apoquel and Cytopoint, once again surpassed the $100 million marketing revenue with sales in the quarter reaching $125 million and $428 million for the full year 2017. Sales of Simparica were $18 million in the quarter, growing 102% over the same period in the prior year. Fish products also contributed to growth with sales of $39 million, growing 44% operationally versus the same quarter last year. Our recently introduced PD vaccine in Norway was the primary driver of growth as it continues to gain share and help increase the penetration of other related vaccines in our portfolio.
Now let's discuss segment revenue. Our International revenue grew 13% operationally in the fourth quarter, with companion animal operational growth of 18% and livestock growth of 11%. The International segment continues to drive growth across multiple dimensions with growth coming from our dermatology portfolio; new products, such as Simparica, our PCV combo vaccine and our PD vaccine; and volume and price from our in-line portfolio.
Turning to some key market highlights in the quarter. In Brazil, we grew 13% operationally, driven by the strength of both our livestock and companion animal businesses. In cattle, investments in our field force have led to increased penetration and coverage in key regions within the market while favorable export market conditions also continued to contribute to growth. In swine, increased sales of IMPROVAC, or Vivax as it's called in Brazil, were driven by higher usage and greater penetration with larger customers. The higher companion animal revenue in Brazil benefited from the continued growth of Simparic through the increased promotional activity and higher veterinary clinic penetration.
In Japan, we experienced operational revenue growth of 27% in the quarter. Growth came from Apoquel as a result of the timing of distributor purchases last year and the additional market penetration we achieved as well as the launch of premium injectable products for livestock.
France grew 23% operationally over the same period last year due to a timing impact related to our price changes and new products to both -- across both companion animal and livestock.
China grew 13% operationally on a continuing strength of the companion animal business, driven by increasing medicalization of pets. Our swine business once again showed modest growth this quarter due to softening pork prices, which we have expected and discussed on recent earnings calls. Our optimistic outlook and long-term view of the market remain unchanged as we continue to invest in our local operations there.
To summarize, a very strong quarter for our International segment with growth across the diversified portfolio, including all of our core species and key markets, favorable market conditions, strategic investments in our portfolio and a focus on execution, are all helping to drive consistent commercial results.
Turning to the U.S. Revenue grew 13% in the fourth quarter. Companion animal grew 15% while livestock grew 11%. Companion animal sales in the quarter were driven primarily by key dermatology products, Simparica and a number of other recently launched products. U.S. dermatology sales for Apoquel and Cytopoint were $86 million for the quarter and exhibited substantial growth over the same quarter in the prior year. While we did see a small decline on a sequential quarter basis, Q1 and Q4 are impacted by seasonality with the warmer spring and summer months experiencing peak activity. Simparica grew over the same quarter last year as DTC investment and field force efforts led to higher clinic penetration in both key corporate accounts and smaller clinics. Additional contributions to companion animal growth came from a number of line extensions to our Vanguard vaccine franchise, DIROBAN, a recently launched product for the treatment of heartworm and CLAVAMOX chewable, a trusted antibiotic in a new easy-to-administer tablet.
Our U.S. livestock business saw a return to growth in the fourth quarter, with sales increasing 11%, thanks to the performance of our cattle and poultry businesses. During the fourth quarter, growth in cattle products was driven by increased sales of premium products, which was supported by a greater risk of disease outbreak and incidents due to the weather as well as the timing of promotional activities in 2016. Our beef cattle business also benefited from higher numbers of animals moving through feedlots than in the comparable 2016 period. Our livestock business continued to be impacted by the Veterinary Feed Directive, or VFD, with another $10 million hit to revenue in the quarter. For the full year 2017, the VFD had about a $40 million impact on revenue. In poultry, there's a weather's portfolio of alternatives to antibiotics and medicated feed additives continue to be the primary driver of growth as certain producers expand their "No Antibiotics Ever" labels. The weather works with customers to provide the necessary product and technical assistance that can help them switch over whenever they choose.
Now moving on to the rest of the P&L. I will quickly cover a few key line items and then move on to our guidance for 2018. Adjusted gross margin of 68.9% increased 450 basis points in the quarter on a reported basis and reflects the benefit of cost improvements in our manufacturing network as well as the reduction of inventory waste charges versus the same quarter last year. Operating expenses in total grew at 2% operationally versus the same period last year, which was significantly lower than the operational revenue growth of 13% as we benefited from the final stages of our operational efficiency initiatives. The adjusted effective tax rate for the quarter was approximately 27.6%. This is higher than the rate in the comparable 2016 period due to the favorable impact of certain one-time discrete items that we experienced in the same quarter last year. Our reported effective tax rate of 43.5% reflects the provisional net tax charge of $212 million in the fourth quarter, which is the result of the recently enacted tax legislation in the U.S. Adjusted net income for the quarter grew 37% operationally through a combination of strong revenue growth and margin expansion and cost improvements in manufacturing and leveraging our global scale and infrastructure. Adjusted diluted EPS grew 39% operationally in the quarter versus the same period in 2016.
Turning now to guidance for the full year 2018. A table of our guidance is included in both our press release and the presentation slides provided for this earnings call. Please note that our guidance for 2018 reflects foreign exchange rates as of early February.
Building off a strong 2017, we see another year of operational revenue growth above the long-term trend we see in the industry overall. Our projected reported revenue range for 2018 is $5.675 billion to $5.8 billion. This represents operational revenue growth of between 5% and 7% over our full year results in 2017. Foreign exchange is expected to add an additional 2% for this revenue growth.
We continue to expect more balanced performance across companion animal and livestock in 2018. Livestock growth is expected to reflect improved conditions in the U.S. and a relatively similar performance in 2017 in our International segment. While companion animal continue to grow faster than livestock, its growth rate will moderate as our dermatology portfolio and other new products grow off a larger base in 2018.
Our adjusted cost of sales as a percentage of revenue is expected to be approximately 32% in 2018, an improvement of around 100 basis points over 2017 and driven by manufacturing cost reductions, price increases and favorable product mix. We expect SG&A for the year to be between $1.37 billion and $1.42 billion. Similar to revenue, foreign exchange is expected to increase these expenses approximately 2% on a reported basis. We will continue to fund our DTC programs for Apoquel and Simparica in the U.S. These programs have been successful, and we expect they will continue to help our sales teams drive market expansion in dermatology and market share in parasiticide.
As our diagnostics pipeline continues to advance, we are beginning to fund additional investments in commercial capabilities in both the U.S. and International to be prepared to offer our customers these products with the level of service and support we offer them on our other portfolios.
We expect R&D expenses to be between $400 million and $420 million, a step-up in the level of spending we have had in prior year. Over the course of 2017, we made a number of decisions to either expand investments or accelerate investments where we saw the opportunity to do so in areas such as monoclonal antibodies and key emerging markets.
The increase in adjusted interest expense and other income deductions reflects the incremental interest expense associated with our recent debt offering.
For the full year 2018, the company expects its adjusted effective tax rate to be in the range of 21% to 22%. The decrease versus prior year is primarily the result of the tax changes enacted in the U.S. in December. The target range for adjusted net income for the full year 2018 is between $1.45 billion and $1.52 billion, representing an operational growth rate of 20% to 26%. Growth here includes the favorable impact of continued operating margin expansion and a lower adjusted effective tax rate. Our guidance for adjusted diluted EPS is between $2.96 and $3.10 for the full year.
Turning to capital allocation. Our priorities remain the same, investment in our own business and internal R&D programs, then external business development opportunity and finally, returning excess capital to the shareholders. With the impact of the recent tax law changes, we'll have greater flexibility to execute on these priorities. I would also point out that given the level of investments we have discussed in manufacturing facility, you should expense capital expenditures in 2018 to be approximately $100 million higher than the $224 million we reported in 2017. In terms of returning excess capital to shareholders, we increased our dividend by 20% for Q1 2018 and had share repurchases of $500 million in 2017. It's worth mentioning that we still have $1 billion left on our current share repurchase program.
To wrap up, we had strong performance in 2017 and see those fundamental business and market drivers continuing into 2018. We have the capital and cash flow generation to invest in growth opportunities across the animal health industry. And we have the talent and capabilities to maintain our market leadership in this attractive market and create more value for our customers and shareholders.
With that, I'll hand things over to the operator to open the line for your questions. Operator?
