Thank you, Gavriel. I'd like to welcome all of you to our conference call, and thank you for joining us today. Having just joined Allot, I have been meeting with people in the company and bringing myself up to speed. I can share with you that I'm impressed with much of what I see. Most notably, the quality and professionalism of the people. I look forward to working with the team and taking the company to the next level.
As you may know, there have been a number of important changes over the past few months. Yigal Jacoby, a co-founder of Allot, took over as Chairman of the Board as of November 10, 2016. Alberto Sessa took over as CFO on January 1, and I joined the team as CEO on February 1.
These changes provide a refresh at the top and enables Allot to execute on the strategy ahead with renewed vigor and focus. Andrei Elefant who will remain with us in a strategic role succeeded in shifting the company's strategy towards the security market. We expect this global growing market to account for an increasing portion of our revenue mix in the coming years.
I believe a significant part of the role of the new management team will be to improve on the company's execution and to realize its full potential. I would now like to share with you some of my initial observations and discuss why I believe Allot is such an interesting company with great long-term growth potential.
As the telecom world continues to evolve, the need to manage the application layer in communication grows with it. This means that as pure connectivity is increasingly commoditized, the need to identify the users and their applications at a high level of granularity increases.
As we all know, network intelligence and traffic control are the core of Allot's business for years, and these enable us to provide and support a growing number of services that are required by cellular and fixed-line operators as well as large enterprises.
Our ability to gather real-time network intelligence on very broad data pipes of Terabits per second allows us to offer services such as consumer security on cellular networks, prevention of distributed denial of service attacks as well as network analytics, traffic shaping, application-based charging and others.
Some of the legacy services, such as traffic shaping have not grown, but still, make up a significant portion of our revenue. Other services, such as consumer security on cellular networks are projected to grow significantly over the next few years, and this is where I see an important growth engine for Allot.
Allot has developed a platform that encompasses both high-capacity, real-time network intelligence and all the applications I mentioned in a single integrated product. This capability and product line are an excellent fit for both the current and developing needs of the telecom markets.
Allot enjoys a large global and installed base with thousands of customers, including hundreds of operators, some of which are top tier. Additionally, our strategic partnership with McAfee, a leading global networking and network security company, with whom we are building a joint product offering, presents a significant opportunity. I believe that the combination of the right products and technology, focused on the right markets together with our large customer base and the people in the company are the foundation on which we will build Allot's future growth.
In the coming quarters, I hope to further elaborate on my long-term vision and execution plans for Allot, with a goal towards solid growth by 2018.
Now, let's move to the results of the fourth quarter of last year. The company reported fourth quarter revenue slightly ahead of guidance at $23.5 million and operating income of $1.8 million for the quarter. For the full year of 2016, revenues were $90.5 million and operating income was $0.4 million.
Value-added services were 42% of booking during Q4, with security representing 42% of total value-added services bookings. The number of large deals in the fourth quarter was 19. 10 of them came from mobile operators, 7 from fixed line service providers, and 2 from a cloud operator. Out of the total, 2 deals were from new customers. Five of these deals were over $1 million each.
Looking ahead, we anticipate revenues in the $80 million to $84 million range for 2017, with the second half of 2017 stronger than the first half. My goal for 2017 is to bring the book-to-bill ratio to above 1, and position the company for a return to solid growth in 2018.
I further expect that quarterly operating expenses in 2017 will be at a slightly higher average rate than in the fourth quarter of 2016, while total OpEx for 2017 should be below the OpEx for 2016. We intend to closely monitor these expenses going forward.
And now, Alberto will take you through the financials, and then I will sum up.
