Thank you, Valter, and thank you, everyone, for joining us today for our 2014 first quarter earnings conference call. During the first quarter of 2014, overall revenue increased 12.2%, with the domestic increase of 13.1% and international at 11.6%. This revenue growth was driven by our Market Force acquisition and higher revenues from new contracts with India, Mexico and Japan, each with multinational Fortune 1000 companies.
Internationally, our gross profit outpaced our revenue growth by increasing 15.5%. Additionally, operating income internationally is over 100% increase. We are thrilled with our international performance and look for the part of our business to be an increasing contributor to our bottom line.
Unfortunately, in the 2014 first quarter, we experienced year-over-year margin pressure domestically. There continues to be a weakness within the retail sector, which has forced some our clients to allocate less of a budget for merchandising, marketing and assembly services. This has resulted in a different and unfavorable margin mix of business for the first quarter. I would remind our shareholders that we have maintained some of these client relationships for upwards of 25 years and they include some of the largest, well-known and globally recognized brands in the world. We recognize the trending of our domestic margins are experiencing and I, along with my management team, are focused on adjusting our existing mix of services and customers with higher margin as our strategy continues to evolve.
On the technology front, we are aggressively rolling out innovation to improve our in-store efficiencies including communications with both our field and clients. To lead this effort, we have appointed Panos Mastrogiannis as our Chief Information Officer and an Executive Officer in the company. Panos has been with SPAR since 1998 and has been a key driver in the evolution of our technology.
Some of our industry-leading IT capabilities include multilingual platforms with bilingual options for global customers that we could implement and enter into new markets and be fully operational in less than 30 days; GPS-enabled maps that show in-store execution in real-time, opportunity tracking systems, along with SPAR's flexibility to address challenges and avoid future problems; data collection capabilities with handheld computers, smartphones and tablets, along with SPAR to include pictures, signatures, GPS; and better supporting on shipment tracking, out-of-stocks, voids, returns and much more. And real-time executive summaries and dashboard that show actual date online and on mobile devices.
We are also delivering on sustainability and green [ph] initiatives, a part of which is powered by our proprietary end-to-end paperless merchandising process. We have our assisted our associates and JV partners automating their merchandising service processes from recruiting to reporting. Our capabilities include identifying and on-boarding qualified experienced merchandisers, deployment to the specific programs, providing client instructions for each specific initiative, executing the project, exceptional reporting, and timely and insightful customer analysis, all enabled at a paperless fashion via SPAR's proprietary platform. Customers can use the SPAR on-the-go application which compiles execution, maps, statistics, pictures and product data, all viewable and communicated through their smartphone or tablet device in real-time.
This sophisticated suite of applications includes efficiency, reduced cost and turnaround time, eliminates errors and aligns with our customers' sustainable and paperless strategies. We have invested years of time and resource against this effort, and I have personally traveled the world to visit with our current and prospective customers. All have been very receptive to this level of technology which is virtually unheard of in the industry. This effort is a differentiator for us and going to be a driving force in our ability to retain and grow our existing customer base, attract and onboard new customers and strategically grow with multinational companies.
We are in the process of executing the planned strategic management of our overall business with a focus on our customers, international businesses and our talent. With our customers and prospects, we are focusing on their objectives and challenges. We are working as a team and addressing the issues in the boardroom so that we can successfully implement a plan to execute in the field.
Internationally, we are working aggressively with our JV partners to build our multinational customer base, expand our services and geographic reach and leverage successful strategies across countries. Strategic management of our talent is focused on talent development, career pathing and professional planning to build, grow and retain the best team possible through the SPAR Group. I'm confident in our ability to implement these strategic plans and that they will result in a strong infrastructure that continually produces reliable and profitable results for both our clients and shareholders.
With that, I would now like to turn the call over to Jim Segreto, our CFO, who will provide greater detail on the numbers. Jim?
