We took a monumental step forward in our company’s growth with the acquisition of Apex Systems, a mid-level IT staffing company that perfectly complements the existing high-end IT offerings of our technology division, Oxford Global Resources. With this acquisition, combined with our organic growth, we exceeded our goal of $1 billion in revenues, and $100 million in EBITDA, and became one of the largest publicly traded professional staffing companies in the world. Tested CircumstancesAs I reflect on 2012 and all that our company accomplished during the year, I can’t help but look back to the recent economic tailspin when the future of many businesses was uncertain. The strength of our business was also tested during this time; however, despite the wavering economy, our service offerings – Technology, Healthcare, and Life Sciences – were able to withstand and deliver strong performances. With our disciplined management, diversified business model, and hardworking employees, we maintained our market share and have since grown to become a perennial leader in the staffing industry.Proven performanceWe ended 2012 with best-in-class results, outperforming our competitors. As a company, we surpassed our financial estimates; hired more than 300 new sales, recruiting and support personnel; paid down our debt faster than expected; and dramatically reduced our capital costs.Below are several highlights from 2012:• Achieved full-year revenues of $1,239.7 million, compared to $597.3 million in 2011 – an increase of 107.6 percent.• Achieved full-year net income of $42.7 million, compared to $24.3 million in 2011.• Acquired Apex Systems, a $791 million IT staffing firm with a nationwide presence in 53 markets.• Achieved a 2012 high of $20.63 per share surpassing our 2011 high of $11.74.• Transferred our stock listing to the New York Stock Exchange.• Commemorated 20 years as a publicly traded company.Our outstanding 2012 results continue to demonstrate the soundness of our business model that is based on diversification in the clients and industries we serve and our focus on providing skilled professionals with in-demand math and science skill sets.Thriving into the futureOver the past few years we’ve seen a strong trajectory in our company’s growth, and I am confident that the fields we serve will remain central to our national and global economies and continue to provide long-term value to our shareholders. To keep at the forefront of our industry, it’s also important for us to continually evaluate our business to see how we can maximize our efficiencies, capitalize on our service offerings, and best position ourselves in the marketplace. With the assistance of an outside consulting firm, our Board of Directors and executive committee are currently working on a new five-year strategic plan that will greatly enhance our opportunities for success.Thank you for your ongoing interest in On Assignment, and I look forward to continuing to report back to you industry-leading results.Sincerely, Peter T. Dameris President and Chief Executive OfficerTo Our Valued ShareholdersTechnology This service offering provides staffing for IT and engineering consultants, project teams, and strategic outsourcing services for mission-critical projects.

Business Overview and History PART I On Assignment, Inc. (NYSE: ASGN), is a leading global provider of highly skilled, hard-to-find professionals in the growing life sciences, healthcare, and technology sectors, where quality people are the key to success. The Company goes beyond matching résumés with job descriptions to match people they know into positions they understand, for contract, contract-to-hire, and direct hire assignments. Our business currently consists of five operating segments: Apex, Oxford (formerly IT and Engineering), Life Sciences, Healthcare and Physician. We were incorporated on December 30, 1985, and thereafter commenced operation of our Lab Support line of business (now included in our Life Sciences operating segment), our first contract staffing line of business. Expansion within the Life Sciences segment and into other industries has primarily been achieved through acquisitions, and utilizing our experience and unique approach in servicing our clients and contract professionals. Since 1985, we have acquired more than 10 companies. On May 15, 2012, we acquired Apex Systems, Inc. (Apex), a privately-owned provider of information technology staffing and services headquartered in Richmond, Virginia. Apex is in its own operating segment, within the Technology sector. On February 28, 2011, we acquired Warphi N.V. (Valesta), a privately-owned provider of specialized clinical research staffing headquartered in Belgium. Valesta is included in the Life Sciences operating segment. On July 31, 2011, we acquired HealthCare Partners, Inc. (HCP), a privately-owned provider of physician staffing headquartered in Atlanta, Georgia. HCP is included in our Physician operating segment. On April 16, 2010, we acquired The Cambridge Group Ltd., a Connecticut-based privately-owned firm specializing in clinical research, IT, and physician staffing services and accordingly, is included in each of our Life Sciences, Oxford and Physician operating segments. On July 19, 2010, the Company acquired Sharpstream Holdings Limited, a London-based privately-owned provider of executive search services in the life sciences sector and is included in our Life Sciences operating segment. Sharpstream provides search services across Europe, Asia, and the United States. Financial information regarding our operating segments and our domestic and international revenues is included under “Financial Statements and Supplementary Data” in Part II, Item 8 of this Annual Report on Form 10-K. Our principal executive office is located at 26745 Malibu Hills Road, Calabasas, California 91301 and our telephone number is (818) 878-7900. We have approximately 130 branch offices in 34 states within the United States and in seven foreign countries. Industry and Market Dynamics The U.S. employment projections published by the U.S. Bureau of Labor Statistics as of February 2012 estimates that total employment for the next decade will grow by 20.5 million jobs, or 14 percent, between 2010 and 2020. By comparison, under the previous estimate for the 2008 to 2018 period, total employment was projected to grow by 10 percent. The increase in projected growth from the prior period is largely due to the relatively lower starting base in 2010, compared to employment levels in 2008. Within the employment industries, the U.S. Bureau of Labor Statistics, according to such projections, estimates that employment growth in the healthcare and social assistance sector will add the most jobs, followed by the professional and business services sector. The Staffing Industry Analysts: Staffing Industry Insight (dated September 2012), an independent staffing industry publication, estimates that total staffing industry revenues were $127 billion in 2012 and are forecasted to be $134 billion in 2013, in each case, up from $117 billion in 2011. The biggest industry segment, contract labor, is forecasted to grow at an annual rate of 6 percent in 2013 with revenues of $105 billion, while permanent placement is forecasted to grow by 6 percent in 2013 with revenues of $16 billion. Within the contract help segment, professional staffing is expected to grow at an annual rate of 7 percent in 2013 to revenues of $56 billion. The temporary staffing (or contract labor) industry is historically cyclical and typically has a strong correlation to employment and GDP growth. We anticipate that our healthcare, life sciences and technology clients will increase their use of outsourced labor through professional staffing firms to meet the need for increases in capacity of their workforce. By using outsourced labor, these end users will benefit from cost structure advantages, improved flexibility to fluctuating demand in business and access to greater expertise. Sales and Fulfillment Our strategy is to serve the needs of our targeted industries by effectively understanding and matching client staffing needs with qualified contract professionals. In contrast to the mass market approach generally used for contract office/clerical and light industrial personnel, we believe effective assignments of contract healthcare, life science, physician and technology professionals require the people involved in making assignments to have significant knowledge of the client’s industry and the ability to assess the specific needs of the client as well as the contract professionals’ qualifications. We believe that face-to-face selling in many circumstances is significantly more effective than the telephonic solicitation of clients, a tactic favored by many of our competitors. We believe our strategy of using industry professionals to develop professional relationships provides us with a competitive advantage in our industry which is recognized by our clients. 5 Our corporate offices are organized to perform many functions that allow staffing consultants and recruiters to focus more effectively on business development and the assignment of contract professionals. These functions include the recruiting and hiring of staffing consultants, recruiters and support staff, as well as ongoing training, coaching and administrative support. Our corporate offices also select, open and maintain branch offices. Clients During the year ended December 31, 2012, we provided contract professionals to approximately 6,511 clients. In 2012, we had no single customer that represented five percent or more of our revenues. All contract assignments, regardless of their planned length, may be terminated with limited notice by the client or the contract professional. The duration of agreements with clients are generally dictated by the contract. Usually, contracts with clients may be terminated with 30 days notice by us or by the clients and, oftentimes, assignments may be terminated with less than one week’s notice. The Contract Professional Contract professionals often work with a number of staffing companies and develop relationships or loyalty based on a variety of factors, including competitive salaries and benefits, availability and diversity of assignments, quality and duration of assignments and responsiveness to requests for placement. Contract professionals seeking traveling positions are also interested in the quality of travel and housing accommodations as well as the quality of the clinical experience while on assignment. Each contract professional’s employment or independent contractor’s relationship with us is terminable at will. A locum tenens physician may generally terminate his or her contract for non-emergency reasons upon 30 or 60 days notice. Hourly wage or contract rates for our contract professionals are established based on their specific skills and whether or not the assignment involves travel away from the professional’s primary residence. Our staffing consultants are our employees or are subcontracted from other corporate entities. For our consultant employees, we pay the related costs of employment including social security taxes, federal and state unemployment taxes, workers’ compensation insurance and other similar costs. After achieving minimum service periods and hours worked, we also provide our contract professional employees with paid holidays and allow participation in our 401(k) Retirement Savings Plan. Strategy We remain committed to growing our operations in the technology, healthcare and life sciences sectors that we currently serve, primarily through supporting our core service offerings and growing our newer service lines of business. In February of 2013, we sold our Nurse Travel business. This decision was based on the relatively small size of the travel nursing market which had contracted significantly more than other healthcare staffing markets during the recession, the fact that its gross margins were significantly lower than the gross margins in our other businesses and the difficulty we believed we would have achieving a reasonable scale. We will continue to look at acquisition opportunities which supplement our internal growth. In 2012, we acquired all of the outstanding shares of Apex Systems, Inc., a privately-owned provider of information technology staffing and services headquartered in Richmond, Virginia. In 2012, we continued to focus on increasing market share in each of our segments, maintaining or increasing our gross margins, expanding our service offerings and controlling our operating costs. We have increased interaction between our segments so that they can share best practices. As part of our initiative to improve our sales capabilities, field operations, and back office processing efficiency, we continue to make strategic investments enhancing our primary business systems. Our front office system (RecruitMax) supports all domestic and foreign Lab Support locations along with our Allied Healthcare operations. Deployment for these platforms began in 2004 and was principally completed in 2008. The RecruitMax application interfaces with the existing enterprise-wide information system, PeopleSoft, used in all of our domestic lines of business and provides additional functionality, including applicant tracking and search tools, customer and candidate contact management and sales management tools. Our next major front office development initiative supporting the Oxford segment is currently underway. Apex uses Bullhorn for its front office system. We continue to extend the use and capabilities of PeopleSoft in domestic and European operations. The Physician staffing segment was migrated to the PeopleSoft platform in 2011. Our ongoing plan is to deploy a common front-office system integrated with the PeopleSoft platform wherever efficiencies can be realized. We improved our pay-bill processing efficiencies by deploying an on-line time collection system. This secure web-based application is a self-service tool that captures time by assignment and allows our customers to provide an electronic approval. This particular extension of PeopleSoft has been fully operational at the Oxford unit for over three years and the roll-out continues for other business segments. Life Sciences and Allied Healthcare largely completed this deployment in 2012. Customer adoption has been very good and we are planning a number of enhancements for meeting unique customer needs throughout 2013. Moderate investments are planned to keep our wide area network and computing platform running with high availability hardware. All primary business operates from a secure data center. 6 We will continue to invest in leasehold improvements as we expand, relocate, and rationalize our branch facilities and leverage favorable commercial real estate terms for cost savings. We believe these improvements should continue to increase the productivity of our staffing consultants and streamline corporate operations. During 2012, we substantially added to the number of recruiters and sales personnel employed by the company. Over the course of the year, the average number of recruiters and sales personnel employed by the company increased 94.0 percent, primarily related to the acquisition of Apex. In 2013, we anticipate that the markets we serve will improve with the economy. We have made small investments in enhancing our permanent placement capabilities and we will continue to invest in our existing businesses to support growth. In addition, we will continue to review acquisition opportunities that may enable us to leverage our current infrastructure and capabilities, increase our service offerings and expand our geographic reach. In late 2012, we engaged a third party to assist and facilitate the development of a new strategic plan. This is similar to the process we completed in 2010. The objectives of that plan were met with the acquisition of Apex. We anticipate that the process will be completed in the middle of 2013. Competition Some of our competitors are larger than us and have substantially greater financial and marketing resources than we do. We also compete with privately-owned temporary staffing companies on a regional and local basis. Frequently, the strongest competition in a particular market is a privately-held local company with established relationships. These companies oftentimes are extremely competitive on pricing. While their pricing strategies are not necessarily sustainable, they can be problematic for us in the short-term. The principal competitive factors in attracting qualified candidates for temporary employment or engagements are salaries, contract rates and benefits, availability and variety of assignments, quality and duration of assignments and responsiveness to requests for placement. We believe that many people seeking temporary employment or engagements through us are also pursuing employment through other means, including other temporary staffing. Therefore, the speed at which we place prospective contract professionals and the availability of appropriate assignments are important factors in our ability to complete assignments of qualified candidates. In addition to having high quality contract professionals to assign in a timely manner, the principal competitive factors in obtaining and retaining clients in the temporary staffing industry are properly assessing the clients’ specific job requirements, the appropriateness of the contract professional assigned to the client, the price of services and the monitoring of client satisfaction. Although we believe we compete favorably with respect to these factors, we expect competition to continue to increase. Operating Segments Apex Our Apex segment, a leading provider of information technology staffing and services, has back-office activities based in Richmond, Virginia with 53 branch offices nationwide supporting our sales, recruiting and field activities. Apex segment revenues for 2012 were $508.7 million and represented 41.0 percent of our total revenues. Apex segment revenues were $791.0 million on a pro forma basis, as if the acquisition had occurred at the beginning of the year. The Staffing Industry Analysts: Staffing Industry Insight (dated September 2012), estimates that the IT staffing market will increase eight percent in 2013. Demand is driven by a shortage of IT professionals with specialized skills. Additionally, the demand for project-based work has created an ideal climate to boost the segment. Our Apex segment provides mission-critical IT operations professionals for contract, contract-to-hire and permanent placement positions to Fortune 1000 and mid-market clients across the United States, and offers consulting services for other select project-based needs. Apex provides staffing and services support for companies from all major industries, including financial services, business services, consumer and industrials, technology, healthcare, government services, and communications. Apex's Consulting Services group is growing to meet the increasing demands of the marketplace. The Consulting Services group supplements Apex's technical staffing solutions by providing deliverable-based services to also help organizations drive better business performance. Apex's consulting services offerings include managed processes, such as support service centers and centers of excellence; managed projects, such as software development, mobile applications, migration services, and consulting; and managed implementations, such as Enterprise Resource Planning and Electronic Health Records. Candidate quality is Apex's priority. Apex's proactive approach and thorough screening process is central to the business. Based upon the customer's requirements, Apex's skill-based recruiters will source candidates utilizing several tools, such as a pipeline of pre-screened candidates, Apex's applicant tracking system with over 1.7 million candidates nationwide, referrals, open houses/networking, social networking, and diversity-based technical communities. Apex segment's professionals include mission-critical daily IT operations professionals across 13 primary skill disciplines that cover the entire IT project life-cycle. This includes skill disciplines within infrastructure, application development, project management, and healthcare IT. These contract professionals encompass a wide variety of backgrounds and levels of experience within information technology. Specialized skills and training are typically dictated by recent technological advancements and trends impacting demand across the enterprise. Such specialization includes healthcare IT, Java, Microsoft, cloud computing, mobile development, and enterprise resource planning. 7 Contract professionals assigned to clients are generally our employees, although clients provide on-the-job supervisors to control and direct professionals and approve hours worked. Apex is responsible for many of the activities typically handled by the client's human resources department. Apex's clients range from the large financial services companies and government contractors to local hospitals seeking support for Internal Classification of Diseases conversions. Assignments in our Apex segment typically vary from four to 12 months, although they can be longer. Apex's competition include TEKsystems, Robert Half International (RHI), Kforce, and Insight Global. Oxford (formerly IT and Engineering) Our Oxford segment (formerly the IT and Engineering segment) is based in Beverly, Massachusetts where all of the segment’s back- office activities are located. Oxford combines international reach with local depth, serving clients through a network of recruiting centers in North America and Europe, and branch offices in major metropolitan markets across the United States. Oxford segment revenues for 2012 were $345.4 million and represented 27.9 percent of our total revenues. The Staffing Industry Analysts: Staffing Industry Insight (dated September 2012) estimates that the IT staffing market will increase eight percent in 2013. Demand in our Oxford business segment is driven by a shortage of IT and engineering professionals with specialized skills that organizations need quickly but cannot find on their own. Additionally, the push for adoption of health information technology and compliance with FDA regulations is accelerating demand for Oxford's services. Oxford assigns highly qualified professionals in select IT and engineering technical disciplines which include enterprise resource planning, business intelligence, customer relationship management, supply chain management, database administration, application development, IT infrastructure, and healthcare applications. Oxford's engineering specialties include hardware, software, mechanical and electrical, as well as validation, regulatory compliance, and quality assurance. Assignments are highly diversified across the client base, averaging fewer than two contract assignments per client. The segment serves the market in two separate operating formats. The first operating format, Oxford International, consists of nine sales and recruiting centers in the U.S. and one in Cork, Ireland that pro-actively recruit skilled IT and engineering professionals and fulfill client needs for temporary consultants and permanent employees across North America and Europe. The right candidates for these assignments often reside in locations that are remote from the client work-site and will travel away from their homes to perform the assignments. The second operating format, Oxford and Associates, consists of 14 branch offices across the United States that recruit technology professionals local to their metropolitan market to fulfill needs for local clients. In each of these formats, we employ both client- oriented sales people and recruiters. Because our Oxford segment concentrates in select disciplines within the IT and engineering markets, our sales people and recruiters specialize in a given discipline. Our competitive advantage comes from our ability to respond very quickly with high quality candidates to a client's request, thus Oxford's tagline “The Right Talent. Right Now.®” Oxford’s professionals are experts in specific information technology and engineering disciplines. Typically, they have a great deal of knowledge and experience in a fairly narrow field which makes them uniquely qualified to fill a given assignment. Contract professionals assigned to clients are generally our employees. Clients provide on-the-job supervisors for these professionals, control and direct their work, and approve all hours worked. Oxford is responsible for many of the activities typically handled by the client’s human resources department, as well as billing, payroll, and related financial activities. In our Oxford segment, we supply services to clients in a wide range of industries. Our clients range from large companies that may, for example, be installing new enterprise-wide computer systems and have a need for a subject matter expert with a specific technical and industry-specific experience, to mid-sized medical device manufacturers who needs specialized mechanical engineers. Assignments in our Oxford segment typically have a term of approximately five months. Oxford’s competition includes local and regional specialty staffing companies as well as large IT consulting firms like Accenture, Inc. and International Business Machines Corporation (IBM), and international staffing firms such as Aerotek and Robert Half International, Inc. Life Sciences Our Life Sciences segment includes our domestic and international life science staffing businesses, which operate from local branch offices in the United States, United Kingdom, Netherlands, Belgium, Canada, Spain and China. At December 31, 2012, we had 48 Life Sciences segment branch offices, of which 13 share office space with our Healthcare segment. Life Sciences segment revenues for 2012 were $162.8 million and represented 13.1 percent of our total revenues. The Staffing Industry Analysts: Staffing Industry Insight (dated September 2012), states that the life sciences professional staffing market will grow by seven percent in 2013. Demand for staffing in our Life Sciences segment is driven primarily by clients with research and development projects across a wide array of industries. We provide locally-based, contract and permanent life science professionals to clients in the biotechnology, pharmaceutical, food and beverage, personal care, chemical, medical device, automotive, municipal, education and environmental industries. We have developed a tailored approach to the assignment-making process that utilizes staffing consultants. Unlike traditional approaches that tend to be focused on telephonic solicitation, our Life Sciences staffing consultants are experienced professionals who work 8 in our branch office network to enable face-to-face meetings with clients and contract professionals. Most of our staffing consultants are either focused on sales and business development or on fulfillment. Sales and business development staffing consultants meet with clients’ managers to understand client needs, formulate position descriptions and assess workplace environments. Fulfillment staffing consultants meet with candidates to assess their qualifications and interests and place these contract professionals on quality assignments with clients. Our Life Sciences segment’s professionals include chemists, clinical research associates, clinical lab assistants, engineers, biologists, biochemists, microbiologists, molecular biologists, biostatisticians, drug safety specialists, SAS programmers, medical writers, food scientists, regulatory affairs specialists, lab assistants and other skilled scientific professionals. These contract professionals range from individuals with bachelor’s and/or master’s degrees and considerable experience to technicians with limited chemistry or biology backgrounds and lab experience. Contract professionals assigned to clients are generally our employees, although clients provide on-the-job supervisors for these professionals. Therefore, clients control and direct the work of contract professionals and approve hours worked, while we are responsible for many of the activities typically handled by the client’s human resources department. Our primary contacts with our clients are a mix of end users and process facilitators. End users consist of lab directors, managers and department heads. Facilitators consist of human resource managers, procurement departments and administrators. Facilitators are more price sensitive than end users who typically are more focused on technical capabilities. Assignments in our Life Sciences segment vary from three to 12 months. We believe our Life Sciences segment is one of the few nationwide temporary staffing providers specializing exclusively in the placement of life science professionals. Although other nationwide temporary staffing companies compete with us with respect to scientific, clinical laboratory, medical billing and collection personnel, many of these companies focus on office/clerical and light and heavy industrial personnel, which account for a significant portion of the overall contract staffing market. These competitors include Manpower, Inc., Kelly Services, Inc., Adecco SA, Yoh Company and the Allegis Group. Healthcare Our Healthcare segment includes our Allied Healthcare and Nurse Travel lines of business. Allied Healthcare operates from various locations throughout the United States. At December 31, 2012, we had 22 Allied Healthcare branch offices in the United States, of which 13 share office space with the Life Sciences segment. Nurse Travel operates from our locations in Cincinnati, Ohio, Tupelo, Mississippi and San Diego, California. Healthcare segment revenues for 2012 were $120.1 million and represented 9.7 percent of our total revenues. We sold Nurse Travel, which was not deemed core to our operations, in February 2013 for $31.0 million in cash. Nurse Travel revenues were $62.2 million or approximately 5 percent of our total revenues. The Staffing Industry Analysts: Staffing Industry Insight (dated September 2012), estimates that the healthcare staffing market will grow by 8 percent in 2013. The combination of healthcare clients facing shortages of operations-critical staff that limit their ability to generate revenues and increased demand for health services and advances in life science and medical technology is expected to create significant demand for workers with specialized science and medical skills. Also influencing the demand for these workers is the departure of mature professionals from the ranks of full-time employment as they retire, reduced hours worked and the pursuit of other career opportunities. Our Healthcare segment provides locally-based and traveling contract professionals to healthcare clients, including hospitals, integrated delivery systems, imaging centers, clinics, physician offices, reference laboratories, universities, managed care organizations, rehabilitation facilities, long-term care facilities and third-party administrators. In doing so, we address healthcare occupations that require “high demand and highly-skilled” staff, such as operating room nurses and health information professionals who are essential to hospitals' ability to care for patients and maintain business and revenues. Our Allied Healthcare line of business has developed a tailored approach to the assignment-making process that utilizes staffing consultants. Staffing consultants are experienced professionals who work in our branch offices and personally meet with clients and contract professionals. Our staffing consultants are typically either focused primarily on sales and business development or on fulfillment. Sales and business development staffing consultants meet with clients to understand their staffing needs, formulate position descriptions and assess workplace environments. Fulfillment staffing consultants meet with candidates to assess their qualifications and interests and place these contract professionals on quality assignments with clients. Our Healthcare segment’s contract professionals include nurses, specialty nurses, health information management professionals, dialysis technicians, surgical technicians, imaging technicians, x-ray technicians, medical technologists, medical assistants, pharmacists, pharmacy technicians, respiratory therapists, phlebotomists, coders, billers, claims processors and collections staff, and dental professionals - including dental assistants, hygienists and dentists and rehabilitation therapists. The nurses and contract professionals we assign to our clients are usually our employees, although clients provide on-the-job supervisors for these nurses and professionals. Therefore, clients control and direct the work of nurses and approve hours worked, while we are responsible for many of the activities typically handled by the client’s human resources department. In our Healthcare segment, we serve a diverse collection of healthcare clients, as mentioned above. Assignments in our Healthcare segment typically have a term of two to 13 weeks. Our Nurse Travel sales, account management, and recruiting functions align with traditional nurse travel companies with an added emphasis on rapid response fulfillment. We employ regional sales directors and account managers to identify and sell a variety of nurse 9 staffing solutions to healthcare clients nationally. Our recruiters seek the most experienced, highly skilled nurses and place them on assignments as contract professionals with healthcare providers. The critical nature of these occupations to drive revenue motivates clients to respond to our ability to rapidly fill open positions with experienced nurses. In the Nurse Travel line of business, our competitors include AMN Healthcare Services, Inc., Cross Country, Inc. and several privately-held companies. In the Allied Healthcare line of business, our competitors include Cross Country, Inc., AMN Healthcare Services, Inc., Kforce Inc. and the Allegis Group. Physician Our Physician segment is the leading provider of physician staffing, known as locum tenens coverage, and permanent physician search services. The majority of our recruiters are located in Salt Lake City, Utah and Atlanta, Georgia. The Physician segment revenues for 2012 were $102.7 million and represented 8.3 percent of our total revenues. The Staffing Industry Analysts: Staffing Industry Insight (dated September 2012), states that the physician staffing market will increase nine percent in 2013. An ongoing shortage of physicians and potential impacts of healthcare reform could fuel future growth. Our Physician staffing business places physicians in a wide range of specialties throughout the United States, as well as Australia and New Zealand, under the brand VISTA, placing them in hospitals, community-based practices and federal, state and local facilities. We provide short and long-term locum tenens services and full-service physician search and consulting services. The physician staffing market requires a high degree of specialized knowledge about credentialing and qualifications, as well as unique insurance requirements that make it more difficult to replicate than certain other types of staffing markets. Our Physician segment operates out of two primary recruitment centers with several branch offices. The sales and fulfillment functions at our Physician segment are similar to those of our competitors. Vista's client sales specialists are organized by geographic territories so that a single individual can handle a client’s physician staffing needs for all disciplines. Vista's recruiters and schedulers are organized by physician specialty and identify physician candidates with the skills, experience and availability to meet our clients’ needs. In addition, we have four branch locations that also carry out recruiting functions. The physicians in our Physician segment come from 33 different specialties including emergency medicine, psychiatry, anesthesiology, radiology, family practice, surgical specialties, internal medicine, pediatrics, obstetrics and gynecology. The physicians we place at clients are independent contractors. Clients assign shifts and approve hours worked, while we are responsible for issuing payments to the physicians for services rendered to our clients. Clients in our Physician segment include hospitals, doctors’ practice groups, large healthcare systems and government agencies. We are called on to supply temporary and permanent doctors because of the difficulty that healthcare providers have finding qualified practitioners. Assignments in our Physician segment typically have a term of two to six weeks. Like our Healthcare segment, our Physician segment competes in the healthcare market, serving hospitals, doctors’ practice groups and private healthcare systems and government administrated healthcare agencies. Our competitors include CHG Healthcare Services, TeamHealth, Inc., Cross Country, Inc. and AMN Healthcare Services, Inc., along with several other privately-held companies providing locum tenens services. Seasonality Demand for our staffing services historically has been lower during the first and fourth quarters due to fewer business days resulting from client shutdowns, adverse weather conditions and a decline in the number of contract professionals willing to work during the holidays. As is common in the staffing industry, we run special incentive programs to keep our contract professionals, particularly nurses, working through the holidays. Demand for our staffing services usually increases in the second and third quarters of the year. In addition, our cost of services typically increases in the first quarter primarily due to the reset of payroll taxes. Employees At December 31, 2012, we employed approximately 2,500 full-time regular employees, including staffing consultants, regional sales directors, account managers, recruiters and corporate office employees. During 2012, we employed approximately 30,850 contract professionals and 1,180 locum tenens physicians. Government Regulation The healthcare industry is subject to extensive and complex federal and state laws and regulations related to professional licensure, certification, conduct of operations, payment for services, payment for referrals and insurance. Our operations are subject to additional state and local regulations that require temporary staffing companies placing healthcare personnel to be licensed or separately registered to an extent beyond that required by temporary staffing companies that only place non-healthcare personnel. To date, we have not experienced any material difficulties in complying with such regulations and obtaining required licensure. 10 Some states require state licensure with associated fees for businesses that employ and/or assign certain healthcare personnel at hospitals and other healthcare facilities. We are currently licensed in all the states that require such licenses. In addition, many of the contract healthcare professionals that we employ are required to be individually licensed and/or certified under applicable state laws. We take reasonable steps to ensure that our contract professionals possess all current licenses and certifications required for each placement. We provide state mandated workers’ compensation insurance, unemployment insurance and professional liability insurance for our contract professionals who are employees and our regular employees. We provide medical malpractice insurance for the non-physician placements through On Assignment Healthcare Staffing. We provide separate medical malpractice insurance coverage for our locum tenens physicians placed through VISTA. These expenses have a direct effect on our cost of services, margins and likelihood of achieving or maintaining profitability. For a further discussion of government regulation associated with our business, see “Risk Factors” within Item 1A of Part I of this Form 10-K.

Item 1A. Risk Factors Our business is subject to a number of risks including, but not limited to, the following: Global market and economic developments could adversely affect our business, financial condition and results of operations. Demand for the contract staffing services that we provide is significantly affected by global market and economic conditions. As economic activity slows, particularly any negative effect on healthcare, research and development and quality control and capital spending, many clients or potential clients reduce their use of and reliance upon contract professionals. During periods of reduced economic activity, we may also be subject to increased competition for market share and pricing pressure. As a result, a recession or periods of reduced economic activity could harm our business and results of operations. Economic conditions remain uncertain. Concerns continue about the systemic impact of energy costs, geopolitical issues, low consumer confidence, high unemployment and underemployment, and the global housing and mortgage markets. As a result of these market conditions, the cost and availability of credit has been and may continue to be adversely affected by illiquid credit markets and wider credit spreads. Continued turbulence in the U.S. and international markets and economies may adversely affect our liquidity and financial condition, as well as the liquidity and financial condition of our lenders and clients. This could impact our ability to draw on all, or a substantial portion, of our credit facilities, refinance maturing liabilities and access the capital markets to meet liquidity needs, as well as expose us to risks in collecting our accounts receivable. If we are not able to remain competitive in obtaining and retaining temporary staffing clients, our future growth will suffer. Agreements may be terminated by clients and contract professionals at will and the termination of a significant number of such agreements would adversely affect our revenues and results of operations. The contract staffing industry is highly competitive and fragmented with limited barriers to entry. We compete in national, regional and local markets with full-service agencies, and in regional and local markets with specialized contract staffing agencies. Many of these companies have significantly greater marketing and financial resources than we do. The success of our business depends upon our ability to continually secure new orders from clients and to fill those orders with our contract professionals. Our agreements do not provide for exclusive use of our services, and clients are free to place orders with our competitors. Each contract professional’s employment or independent contractor’s relationship with us is terminable at will. If clients terminate a significant number of our staffing agreements or assignments and we are unable to generate new contract staffing orders to replace lost revenues or a significant number of our contract professionals terminate their employment with us and we are unable to find suitable replacements, the growth of our business could be adversely affected and our revenues and results of operations could be harmed. As a result, it is imperative to our business that we maintain positive relationships with our clients and contract professionals. To the extent that competitors seek to gain or retain market share by reducing prices or increasing marketing expenditures, we could lose revenues and our margins could decline, which could seriously harm our operating results and cause the trading price of our stock to decline. As we expand into new geographic markets, our success will depend in part on our ability to gain market share from competitors. We expect competition for clients to increase in the future, and the success and growth of our business depends on our ability to remain competitive. In addition, we continue to participate in an increasing number of third party contracts as a subcontractor and that requires us to participate in vendor management contracts, which may subject us to greater risks or lower margins. If Apex is unable to sustain its rate of growth, the growth prospects and future results of On Assignment are likely to be adversely affected. Over the past eight years, Apex has undergone revenue and earnings growth. This growth has come from Apex's focus on information technology staffing, increased market share with existing clients, addition of new clients, national presence and infrastructure that promotes high operating leverage. There is no assurance that Apex will be able to continue this pace of growth in the future. Such growth also could be negatively affected by many factors, including future technology industry conditions, the effects of integration with the Company's business or macroeconomic events. If Apex's growth rate slows, or if it fails to grow at the pace anticipated by the Company, the growth prospects and future results of the Company are likely to be adversely affected. 13 Fluctuation in patient occupancy rates at client facilities could adversely affect demand for services of our Healthcare and Physician segments and our results of operations. Client demand for our Healthcare and Physician segment services is significantly impacted by changes in patient occupancy rates at our hospital and healthcare clients’ facilities. Increases in occupancy often result in increased client need for contract professionals before full-time employees can be hired. During periods of decreased occupancy, however, hospitals and other healthcare facilities typically reduce their use of contract professionals before laying off their regular, full-time employees. During periods of decreased occupancy, we may experience increased competition to service clients, including pricing pressure. Occupancy at certain healthcare clients’ facilities also fluctuates due to the seasonality of some elective procedures and patients declining elective procedures. Periods of decreased occupancy at client healthcare facilities could materially adversely affect our results of operations. If we cannot attract, develop and retain qualified and skilled sales and recruiting staff, our business growth will suffer. A key component of our ability to grow our business is our ability to attract, develop and retain qualified and skilled sales and recruiting staff, particularly persons with industry experience. The available pool of qualified staffing consultant candidates is limited, and further constrained by the industry practice of entering into non-compete agreements with these employees, which may restrict their ability to accept employment with other staffing firms, including us. We cannot assure that we will be able to recruit, develop and retain qualified sales and recruiting staff in sufficient numbers, or that our staffing consultants will achieve productivity levels sufficient to enable growth of our business. Failure to attract and retain productive sales and recruiting staff could adversely affect our business, financial condition and results of operations. If we are unable to attract and retain qualified contract professionals, our business could be negatively impacted. Our business is substantially dependent upon our ability to attract and retain contract professionals who possess the skills, experience, and licenses, as required, to meet the specified requirements of our clients. We compete for such contract professionals with other temporary staffing companies and with our clients and potential clients. There can be no assurance that qualified healthcare, nursing, life sciences, physician, IT and engineering professionals will be available to us in adequate numbers to staff our operating segments. Moreover, our contract professionals are often hired to become regular employees of our clients. Attracting and retaining contract professionals depends on several factors, including our ability to provide contract professionals with desirable assignments and competitive benefits and wages. The cost of attracting and retaining contract professionals may be higher than we anticipate and, as a result, if we are unable to pass these costs on to our clients, our likelihood of achieving or maintaining profitability could decline. In periods of high unemployment, contract professionals frequently opt for full-time employment directly with clients and, due to a large pool of available candidates, clients are able to directly hire and recruit qualified candidates without the involvement of staffing agencies. If we are unable to attract and retain a sufficient number of contract professionals to meet client demand, we may be required to forgo staffing and revenue opportunities, which may hurt the growth of our business. Reclassification of our independent contractors by tax authorities could materially and adversely affect our business model and could require us to pay significant retroactive wages, taxes and penalties. We consider our locum tenens physicians to be independent contractors rather than employees. As such, we do not withhold or pay income or other employment related taxes, or provide workers’ compensation insurance for them. Our classification of locum tenens physicians as independent contractors is consistent with general industry standard, but can nonetheless be challenged by the contractors themselves or by relevant taxing authorities. If federal or state taxing authorities determine that locums tenens physicians engaged as independent contractors are employees, our business model for that segment would be materially and adversely affected. Although we believe we qualify for safe harbor under the provisions of Section 530 of the Revenue Act of 1978, Pub. L. No. 95-600, and any similar applicable state laws, we could incur significant liability for past wages, taxes, penalties and other employment benefits if we could not so qualify. In addition, many states have laws that prohibit non-physician owned companies from employing physicians. If our independent contractor physicians are classified as employees, we could be found in violation of such state laws, which could subject us to liability in those states and thereby negatively impact our profitability. Our costs of providing travel and housing for traveling contract professionals may be higher than we anticipate and, as a result, our margins could decline. If our travel and housing costs, including the costs of airline tickets, rental cars, apartments and rental furniture for our traveling contract professionals exceed the levels we anticipate, and we are unable to pass such increases on to our clients, our margins may decline. To the extent the length of our apartment leases exceed the terms of our staffing contracts, we bear the risk that we will be obligated to pay rent for housing we do not use. If we cannot source a sufficient number of appropriate short-term leases in regional markets, or if, for any reason, we are unable to efficiently utilize the apartments we do lease, we may be required to pay rent for unutilized or underutilized housing. Effective management of travel costs will be necessary to prevent a decrease in gross profit and gross and operating margins. Future changes in reimbursement trends could hamper our Healthcare and Physician segments clients’ ability to pay us, which would harm our financial results. Many of our Healthcare and Physician segments’ clients are reimbursed under the federal Medicare program and state Medicaid programs for the services they provide. In recent years, federal and state governments have made significant changes in these programs that 14 have reduced reimbursement rates. In addition, insurance companies and managed care organizations seek to control costs by requiring that healthcare providers, such as hospitals, discount their services in exchange for exclusive or preferred participation in their benefit plans. Future federal and state legislation or evolving commercial reimbursement trends may further reduce, or change conditions for, our clients’ reimbursement. Limitations on reimbursement could reduce our clients’ cash flows, thereby hampering their ability to pay us. If our insurance costs increase significantly, these incremental costs could negatively affect our financial results. The costs related to obtaining and maintaining workers’ compensation insurance, medical malpractice insurance, professional and general liability insurance and health insurance for our contract professionals have been increasing. If the cost of carrying this insurance continues to increase significantly, this may reduce our gross and operating margins and affect our financial results. We may be subject to increases in payroll-related costs and unemployment insurance taxes, resulting in lower margins. We currently pay federal, state and local payroll costs and taxes for our corporate employees and contract professional employees. If we are subject to significant increases in costs associated with payroll and unemployment taxes, we may not be able to increase client bill rates to cover the additional expense and this may reduce our gross and operating margins and affect our financial results. Significant legal actions and claims could subject us to substantial uninsured liabilities, result in damage to our business reputation, discontinuation of our client relationships and adversely affect our recruitment and retention efforts. In recent years, we have been subject to an increasing number of legal actions alleging malpractice, vicarious liability, intentional torts, negligent hiring, discrimination, sexual harassment, retroactive entitlement to employee benefits, violation of wage and hour requirements, or related legal theories. We may be subject to liability in such cases even if the contribution to the alleged injury was minimal. Many of these actions involve large claims and significant defense costs. In addition, we may be subject to claims related to torts or crimes committed by our corporate employees or contract professionals. In most instances, we are required to indemnify clients against some or all of these risks. A failure of any of our corporate employees or contract professionals to observe our policies and guidelines intended to reduce these risks; relevant client policies and guidelines or applicable federal, state or local laws, rules and regulations could result in negative publicity, payment of fines or other damages. We may be subject to possible claims by our clients related to errors and omissions, misuse of proprietary information, breach of confidentiality, discrimination and harassment, theft and other criminal activity, malpractice and other claims stemming from the improper activities or alleged activities of our contract professionals. To protect ourselves from the cost of these types of claims, we maintain workers’ compensation, medical malpractice, errors and omissions, employment practices and general liability insurance coverage in amounts and with deductibles that we believe are appropriate for our operations. Our coverage includes a large retention amount, and our insurance coverage may not cover all claims against us or continue to be available to us at a reasonable cost. If we are unable to maintain adequate insurance coverage, we may be exposed to substantial liabilities. Claims raised by clients stemming from the improper actions of our contract professionals, even if without merit, could cause us to incur significant expense associated with the costs or damages related to such claims. Further, such claims by clients could damage our business reputation and result in the discontinuation of client relationships. Any associated negative publicity could adversely affect our ability to attract and retain qualified contract professionals in the future. We operate in a regulated industry and changes in regulations or violations of regulations may result in increased costs or sanctions that could reduce our revenues and profitability. Our organization is subject to extensive and complex federal and state laws and regulations including but not limited to laws and regulations related to professional licensure, payroll tax, conduct of operations, payment for services and payment for referrals. If we fail to comply with the laws and regulations that are directly applicable to our business, we could suffer civil and/or criminal penalties or be subject to injunctions or cease and desist orders. Extensive and complex laws that apply to our hospital and healthcare facility clients, including laws related to Medicare, Medicaid and other federal and state healthcare programs, could indirectly affect the demand or the prices paid for our services. For example, our hospital and healthcare facility clients could suffer civil and/or criminal penalties and/or be excluded from participating in Medicare, Medicaid and other healthcare programs if they fail to comply with the laws and regulations applicable to their businesses. In addition, our hospital and healthcare facility clients could receive reduced reimbursements or be excluded from coverage because of a change in the rates or conditions set by federal or state governments. In turn, violations of or changes to these laws and regulations that adversely affect our hospital and healthcare facility clients could also adversely affect the prices that these clients are willing or able to pay for our services. U.S. healthcare legislation could negatively impact our results of operations. In March 2010, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively, the Acts) were signed into U.S. law. The Acts represent comprehensive healthcare reform legislation that, in addition to other provisions, will require that we provide healthcare coverage to our temporary employees in the United States or incur penalties. Although our intent is to bill these costs to our customers, there can be no assurance that we will be able to increase client bill rates in a sufficient amount to cover the increased costs. This may reduce our gross and operating margins and negatively impact our financial results. Additionally, since significant provisions of the Acts will not become effective until 2014, possible future changes to the Acts could significantly impact any 15 estimates we develop during that period. While we are unable at this time to estimate the net impact of the Acts, we believe the net financial impact on our results of operations could be significant. We may not successfully make or integrate acquisitions, which could harm our business and growth. As part of our growth strategy, we intend to opportunistically pursue selected acquisitions. We compete with other companies in the professional staffing and consulting industries for acquisition opportunities, and we cannot assure that we will be able to affect future acquisitions on commercially reasonable terms or at all. To the extent we enter into acquisition transactions in the future, we may experience: • • • • • • • • • • delays in realizing or a failure to realize the benefits, cost savings and synergies that we anticipate; difficulties or higher-than-anticipated costs associated with integrating any acquired companies into our businesses; attrition of key personnel from acquired businesses; diversion of management’s attention from other business concerns; inability to maintain the business relationships and reputation of the acquired companies; difficulties in integrating the acquired companies into our information systems, controls, policies and procedures; additional risks relating to the businesses or industry of the acquired companies that are different from ours; unexpected liabilities, costs or charges; unforeseen operating difficulties that require significant financial and managerial resources that would otherwise be available for the ongoing development or expansion of our existing operations; and impairment related to goodwill and other identifiable intangible assets acquired To undertake more transactions, additional financing may be necessary and, if used, would result in additional debt, dilution of outstanding equity, or both. We may face unexpected contingent liabilities arising from these or future acquisitions that could harm our business. Impairment of goodwill or identifiable intangible assets could materially impact future results of operations. We have approximately $498.4 million in goodwill and $263.8 million in identifiable intangible assets at December 31, 2012. As part of the testing of goodwill impairment, Accounting Standards Codification Topic 350, Intangibles - Goodwill and Other, requires the Company to estimate the fair value of its reporting units on at least an annual basis and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment tests consist of comparing the fair value of a reporting unit with its carrying amount including goodwill. We determine the fair value of each reporting unit based upon a weighted average calculation using the fair value derived from a discounted cash flow analysis and a market approach analysis. Discounted cash flows are developed for each reporting unit based on assumptions including revenue growth expectations, gross margins, operating expense projections, working capital, capital expense requirements and tax rates. The multi-year financial forecasts for each reporting unit used in the cash flow models considered several key business drivers such as new product lines, historical performance and industry and economic trends, among other considerations. The market approach considers multiples of financial metrics, primarily EBITDA, based on trading multiples of a group of guideline public companies in the staffing industry, which multiples are then applied to the corresponding financial metrics of our reporting units to derive an indication of fair value. There are inherent uncertainties related to the factors, and management's judgment in applying these factors. At October 31, 2012, we performed our annual goodwill impairment test and concluded that there was no impairment. Future declines in our market capitalization or any other impairment indicators subsequent to the balance sheet date could be an early indication that remaining goodwill may become impaired in the future. Although a future impairment of goodwill and indefinite lived identifiable intangible assets would not affect our cash flow, it would negatively impact our operating results. Intangible assets with indefinite lives consist of trademarks. We test trademarks for impairment on an annual basis, on October 31. In order to test the trademarks for impairment, we determine the fair value of the trademarks and compare such amount to its carrying value. We determine the fair value of the trademarks using a projected discounted cash flow analysis based on the relief-from-royalty approach. The principal factors used in the discounted cash flow analysis requiring judgment are projected net sales, discount rate, royalty rate and terminal value assumption. The royalty rate used in the analysis is based on transactions that have occurred in our industry. Intangible assets having finite lives are amortized over their useful lives and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Customer relations are amortized using an accelerated method. Contractor relations and non- compete agreements are amortized using the straight-line method. We did not have any impairment of indefinite lived or finite lived intangibles in 2012. We are subject to business risks associated with international operations, which could make our international operations significantly more costly. During 2012, we had international sales in all countries in the European Union, in Canada, New Zealand and Australia. In 2012, our international operations comprised approximately 6.3 percent of total sales compared with 11.4 percent and 7.0 percent in 2011 and 2010, respectively. We have limited experience in marketing, selling and supporting our services outside of North America. Operations in certain markets are subject to risks inherent in international business activities, including: • • • fluctuations in currency exchange rates; complicated work permit requirements; varying economic and political conditions; 16 • • • • seasonal reductions in business activity during the summer months in Europe and Asia; overlapping or differing tax structures; difficulties collecting accounts receivable; and regulations concerning pay rates, benefits, vacation, union membership, redundancy payments and the termination of employment. Our inability to effectively manage our international operations could result in increased costs and adversely affect our results of operations. Adverse results in tax examinations could subject us to unforeseen liabilities and impact our financial results. We are subject to periodic tax audits. Adverse findings or assessments made by taxing authorities as the result of an audit could have an adverse effect on our financial results, if we are unable to sustain our position with the relevant jurisdiction. If our information systems do not function in a cost effective manner, our business will be harmed. The operation of our business is dependent on the proper functioning of our information systems. In 2012, we continued to upgrade our information technology systems, including our PeopleSoft and Recruitmax Technology enterprise-wide information systems used in daily operations to identify and match staffing resources and client assignments, track regulatory credentialing, manage scheduling, and perform billing and accounts receivable functions. If the systems fail to perform reliably or otherwise do not meet our expectations, or if we fail to successfully complete the implementation of other modules of the systems, we could experience business interruptions that could result in deferred or lost sales. Our information systems are vulnerable to fire, storm, flood, power loss, telecommunications failures, physical or software break-ins, viruses, security breaches and similar events. Our network infrastructure is currently located at our facility in Salt Lake City, Utah. As a result, any system failure or service outage at this primary facility could result in a loss of service for the duration of the failure of the outage. Our location in Southern California is susceptible to earthquakes and has experienced power shortages and outages in the past, which could result in system failures or outages. If our information systems fail or are otherwise unavailable, these functions would have to be accomplished manually, which could impact our ability to respond to business opportunities quickly, to pay our staff in a timely fashion and to bill for services efficiently. The loss of key members of our senior management team could adversely affect the execution of our business strategy and our financial results. We believe that the successful execution of our business strategy and our ability to build upon the significant recent investments in our business and acquisitions of new businesses depends on the continued employment of key members of our senior management team. If any members of our senior management team become unable or unwilling to continue in their present positions, our financial results and our business could be materially adversely affected. Failure of internal controls may leave us susceptible to errors and fraud. Our management, including our CEO and CFO, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable assurance that the objectives of the control system are met. Furthermore, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, would be detected. Failure to comply with restrictive covenants under our debt instruments could trigger prepayment obligations or additional costs. Our failure to comply with restrictive covenants under our credit facilities and other debt instruments could result in an event of default, which, if not cured or waived, could result in the requirement to repay such borrowings before their due date. Some covenants are tied to our operating results and thus may be breached if we do not perform as expected. The lenders may require fees and expenses to be paid or other changes to terms in connection with waivers or amendments. If we are forced to refinance these borrowings on less favorable terms, our results of operations and financial condition could be adversely affected by increased costs and/or rates. The trading price of our common stock has experienced significant fluctuations, which could make it difficult for us to access the public markets for financing or use our common stock as consideration in a strategic transaction. In 2012, the trading price of our common stock experienced significant fluctuations, ranging from a high of $20.93 to a low of $10.65. The closing price of our common stock on the NYSE was $24.85 on March 8, 2013. Our common stock may continue to fluctuate widely as a result of a large number of factors, many of which are beyond our control, including: • • • • • • • period to period fluctuations in our financial results or those of our competitors; failure to meet previously announced guidance or analysts’ expectations of our quarterly results; announcements by us or our competitors of acquisitions, significant contracts, commercial relationships or capital commitments; commencement of, or involvement in, litigation; any major change in our board or management; changes in government regulations, including those related to Medicare and Medicaid reimbursement policies; recommendations by securities analysts or changes in earnings estimates; 17 • • • • • • announcements about our earnings that are not in line with analyst expectations; the volume of shares of common stock available for public sale; announcements by our competitors of their earnings that are not in line with analyst expectations; sales of stock by us or by our shareholders; short sales, hedging and other derivative transactions in shares of our common stock; and general economic conditions, slow or negative growth of unrelated markets and other external factors. The stock market has experienced extreme price and volume fluctuations that have affected the trading prices of the common stock of many companies involved in the temporary staffing industry. As a result of these fluctuations, we may encounter difficulty should we determine to access the public markets for financing or use our common stock as consideration in a strategic transaction. Our results of operations may vary from quarter to quarter as a result of a number of factors, which may make it difficult to evaluate our business and could cause instability in the trading price of our common stock. Factors that may cause our quarterly results to fluctuate include: • • • the level of demand for our temporary staffing services and the efficiency with which we source and assign our contract professionals and support our staffing consultants in the execution of their duties; changes in our pricing policies or those of our competitors; and our ability to control costs and manage our accounts receivable balances. Most temporary staffing companies experience seasonal declines in demand during the first and fourth quarters, as a result of fewer business days and the reduced number of contract professionals willing to work during the holidays. Historically, we have experienced variability in the duration and depth of these seasonal declines, which in turn have materially affected our quarterly results of operations and made period-to-period comparisons of our financial and operating performance difficult. If our operating results are below the expectations of public market analysts or investors in a given quarter, the trading price of our common stock could decline. Future sales of our common stock and the future exercise of options may cause the market price of our common stock to decline and may result in substantial dilution. We cannot predict what effect, if any, future sales of our common stock, or the availability of our common stock for sale will have on the market price of our common stock. Sales of substantial amounts of our common stock in the public market by management or us, or the perception that such sales could occur, could adversely affect the market price of our common stock and may make it more difficult for you to sell your common stock at a time and price which you may deem appropriate. We have adopted anti-takeover measures that could prevent a change in our control. We adopted a shareholder rights plan that has certain anti-takeover effects and will cause substantial dilution to a person or group that attempts to acquire us in a manner or on terms that have not been approved by our board of directors. This plan could delay or impede the removal of incumbent directors and could make more difficult a merger, tender offer or proxy contest involving us, even if such events could be beneficial, in the short-term, to the interests of our shareholders. In addition, such provisions could limit the price that some investors might be willing to pay in the future for shares of our common stock. Our certificate of incorporation and bylaws contain provisions that limit liability and provide for indemnification of our directors and officers, and provide that our stockholders can take action only at a duly called meeting of stockholders. These provisions and others also may have the effect of deterring hostile takeovers or delaying changes in control or management. Provisions in our corporate documents and Delaware law may delay or prevent a change in control that our stockholders consider favorable. Provisions in our certificate of incorporation and bylaws could have the effect of delaying or preventing a change of control or changes in our management. These provisions include the following: • Our board of directors has the right to elect directors to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors. • Our stockholders may not act by written consent. In addition, a holder or holders controlling a majority of our capital stock would not be able to take certain actions without holding a stockholder’s meeting, and only stockholders owning at least 50 percent of our entire voting stock must request in writing in order to call a special meeting of stockholders (which is in addition to the authority held by our board of directors to call a special stockholder meeting). Stockholders must provide advance notice to nominate individuals for election to the board of directors or to propose matters that can be acted upon at a stockholders’ meeting. These provisions may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company. • Our board of directors may issue, without stockholder approval, up to one million shares of undesignated or “blank check” preferred stock. The ability to issue undesignated or “blank check” preferred stock makes it possible for our board of directors to issue preferred • 18 stock with voting or other rights or preferences that could impede the success of any attempt or make it more difficult for a third party to acquire us. As a Delaware corporation, we are also subject to certain Delaware anti-takeover provisions, including Section 203 of the Delaware General Corporation Law. Under these provisions, a corporation may not engage in a business combination with any large stockholders who hold 15 percent or more of our outstanding voting capital stock in a merger or business combination unless the holder has held the stock for 3 years, the board of directors has expressly approved the merger or business transaction or at least two-thirds of the outstanding voting capital stock not owned by such large stockholder approve the merger or the transaction. These provisions of Delaware law may have the effect of delaying, deferring or preventing a change of control, and may discourage bids for our common stock at a premium over its market price. In addition, our board of directors could rely on these provisions of Delaware law to discourage, prevent or delay an acquisition of us. Item 1B. Unresolved Staff Comments Not applicable. Item 2. Properties As of December 31, 2012, we leased approximately 37,200 square feet of office space through November 2021 for our field support and corporate headquarters in Calabasas, California. Additionally, we leased 16,600 square feet of office space through February 2016 for our field support offices in Blue Ash, Ohio. As of December 31, 2012, we leased approximately 56,000 square feet of office space through December 2016 at our VISTA headquarters in Salt Lake City, Utah; 48,300 square feet of office space through December 2015 at our Oxford headquarters in Beverly, Massachusetts; and 21,700 square feet of office space through March 2017 at our Apex headquarters in Richmond, Virginia. In addition, as of December 31, 2012, we lease approximately 670,000 square feet of total office space in approximately 130 branch office locations in the United States, United Kingdom, Netherlands, Belgium, Ireland, Spain, China and Canada. A branch office typically occupies space ranging from approximately 1,000 to 5,000 square feet with lease terms that typically range from six months to five years. Item 3. Legal Proceedings We are involved in various legal proceedings, claims and litigation arising in the ordinary course of business. However, based on the facts currently available, we do not believe that the disposition of matters that are pending or asserted will have a material effect on our financial position, results of operations or cash flows. Item 4. Mine Safety Disclosures Not applicable. 19 PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Price Range of Common Stock Our common stock is listed on the New York Stock Exchange, or NYSE, under the symbol ASGN. Prior to August 31, 2012, our common stock was listed on the NASDAQ Global Select Market, or Nasdaq. The following table sets forth the range of high and low sales prices as reported on the Nasdaq and the NYSE, as applicable for each quarterly period within the two most recent fiscal years. At March 8, 2013, we had approximately 70 holders of record, approximately 8,700 beneficial owners of our common stock and 53,084,637 shares outstanding. Year Ended December 31, 2012 First Quarter Second Quarter Third Quarter Fourth Quarter Year Ended December 31, 2011 First Quarter Second Quarter Third Quarter Fourth Quarter Price Range of Common Stock High Low $ $ $ $ $ $ $ $ 18.25 19.37 20.93 20.74 10.87 11.67 11.25 11.94 $ $ $ $ $ $ $ $ 10.65 14.48 14.50 18.00 7.77 8.06 6.27 6.68 Since inception, we have not declared or paid any cash dividends on our common stock, and we currently plan to retain all earnings to support the development and expansion of our business and we have no present intention of paying any dividends on our common stock in the foreseeable future. However, the board of directors periodically reviews our dividend policy to determine whether the declaration of dividends is appropriate. Terms of our senior credit facility restrict our ability to pay dividends of more than $2.5 million in total over the term of the agreement. Stock Performance Graph The following graph compares the performance of On Assignment’s common stock price during the period from December 31, 2007 to December 31, 2012 with the composite prices of companies listed on the NYSE, the NASDAQ and of companies included in the SIC Code No. 736—Personnel Supply Services Companies Index.

Apex revenues for the year ended December 31, 2012 were $508.7 million or 41.0 percent of total revenues. Apex was acquired on May 15, 2012 and is reported in the Apex segment. Oxford segment revenues increased $78.6 million, or 29.5 percent, comprised of a 23.5 percent increase in the average number of contract professionals on assignment, a 4.7 percent increase in average bill rate and a $1.1 million increase in conversion and permanent 23 placement revenue. Revenues for Oxford's Healthcare IT line of business increased by approximately 119 percent, the Engineering - Regulatory and Compliance line of business increased by approximately 39 percent, while the remaining lines of business grew by approximately 17 percent. Due to the limited availability of senior IT and engineering consultants, the demand for our services have increased. We have continued to focus on diversifying this segment across clients and industries and have selectively added staffing consultants necessary for current and future growth. In their September report Staffing Industry Analysts say the US IT Staffing market “will attain an all-time high of $24.9 billion in 2013”. Life Sciences segment revenues increased $7.5 million, or 4.8 percent, comprised of a 5.0 percent increase in the average number of contract professionals on assignment and a 0.5 percent increase in the average bill rate, which was slightly offset by a $0.8 million decrease in conversion and permanent placement revenue. The increase was achieved despite the termination in early 2012 of a low-margin account that generated approximately $3.1 million in revenue in 2011. The year-over-year increase in revenues was attributable to inclusion of a full year's operating results from Valesta, which was acquired on February 28, 2011 and increased demand from our other service offerings as our clients end markets improved. In 2012, Valesta accounted for $24.5 million in revenues up from $20.4 million in 2011. Healthcare segment (comprised of our Nurse Travel and Allied Healthcare lines of business) revenues increased $25.5 million, or 27.0 percent. Nurse Travel revenues were $62.2 million, up $12.5 million year-over-year primarily due to higher revenues from staffing services supporting customers experiencing labor disruptions ($13.5 million in revenues during the year ended December 31, 2012 and $7.1 million in 2011). The average number of nurses on assignment increased 14.1 percent, which was slightly offset by a 1.3 percent decrease in the average bill rate. Allied Healthcare revenues were $57.9 million, up $13.0 million, or 28.8 percent. The average number of contract professionals on assignment increased 23.4 percent, the average bill rate increased 2.0 percent, and conversion and permanent placement revenue increased $0.3 million. The increase in revenues was attributable to improved economic trends in the healthcare sector, which resulted in a higher number of contract professionals on assignment, open orders and average bill rates. The Allied Healthcare operating environment continued to demonstrate signs of improvement as economic trends in our end markets showed signs of stabilization and growth as evidenced by year- over-year growth in the number of clients and contractors on billing, average bill rate and billable hours. Although the Healthcare segment remains soft, we continue to see signs of improvement in demand for contract professionals. Physician segment revenues increased $22.1 million, or 27.4 percent. The increase in Physician segment revenues was attributable to inclusion of a full year's operating results from HCP, which was acquired on July 31, 2011 and a $7.8 million increase in our legacy physician business. HCP accounted for $25.5 million in revenues in 2012 up from $11.2 million in 2011. The increase in legacy physician revenues was due to a 4.3 percent increase in the average number of physicians placed and working, a 4.8 percent increase in average bill rate and a $0.6 million increase in direct hire and conversation fee revenues. Gross Profit and Gross Margins Gross Profit by segment (in thousands): Apex Oxford (formerly IT and Engineering) Life Sciences Healthcare Physician Year Ended December 31, 2012 2011 Gross Profit Gross Margin Gross Profit Gross Margin $ 140,669 27.7% $ 122,043 55,874 34,282 31,455 35.3% 34.3% 28.5% 30.6% — 94,967 52,643 26,637 25,858 $ 384,323 31.0% $ 200,105 —% 35.6% 33.9% 28.2% 32.1% 33.5% The year-over-year gross profit increase was primarily due to higher revenues, which was partially offset by a 250 basis point contraction in consolidated gross margin. The decrease in gross margin was primarily attributable to the inclusion of Apex, which has a lower gross margin than our other segments. Oxford segment gross profit increased $27.1 million, or 28.5 percent, primarily due to a $78.6 million, or 29.5 percent increase in revenues, which was partially offset by a 26 basis point contraction in gross margin. The contraction in gross margin was primarily due to increases in consultant payroll taxes and benefits offset by a $1.1 million increase in direct hire and conversion fee revenue. Life Sciences segment gross profit increased $3.2 million, or 6.1 percent. The increase in gross profit was primarily due to a 4.8 percent increase in revenues and a 43 basis point expansion in gross margin. The expansion in gross margin was due to a 1.9 percent increase in bill/pay spread, which was partially offset by an increase in travel related expense, an increase in payroll taxes related to higher European payroll tax rates for Valesta employees, and a $0.8 million decrease in direct hire and conversion fee revenue. Healthcare segment gross profit increased $7.6 million, or 28.7 percent. The increase in gross profit was due to a 27.0 percent increase in revenues and a 38 basis point expansion in gross margin. Within this segment, Allied Healthcare gross profit increased 28.8 percent, while gross margin was flat. Nurse Travel gross profit increased 28.6 percent and gross margin increased 66 basis points. The expansion in gross 24 margin was primarily due to a $6.4 million increase in revenues from labor disruption in 2012 which have higher gross margin than other Nurse Travel revenues. Physician segment gross profit increased $5.6 million, or 21.6 percent. The increase in gross profit was due to a $22.1 million, or 27.4 percent increase in revenues, partially offset by a 145 basis point contraction in gross margin. The contraction in gross margin was primarily due to a 7.7 percent decrease in bill/pay spread in part related to a greater concentration of government work at HCP, which has a lower gross margin than the legacy Physician business. The Physician segment also experienced an increase in non-billable expenses, which was partially offset by a $0.5 million favorable actuarial adjustment to our medical malpractice insurance expense. Selling, General and Administrative Expenses. Selling, general and administrative (SG&A) expenses include field operating expenses, such as costs associated with our network of staffing consultants and branch offices for each of our five segments, including staffing consultant compensation, rent, other office expenses, marketing and recruiting expenses for our contract professionals. SG&A expenses also include our corporate and branch office support expenses, such as the salaries of corporate operations and support personnel, recruiting and training expenses for field staff, marketing staff expenses, expenses related to being a publicly-traded company and other general and administrative expenses. For the year ended December 31, 2012, SG&A expenses increased $120.2 million, or 78.4 percent, to $273.5 million from $153.4 million in 2011. The increase in SG&A expenses was primarily due to (i) $88.6 million of SG&A expenses from Apex, which was acquired on May 15, 2012, (ii) $10.6 million in acquisition costs primarily related to the recent acquisition of Apex, and (iii) $20.8 million, or 18.1 percent increase, in compensation and benefits excluding Apex. The increase in compensation and benefits was due to a $9.0 million increase in compensation expenses primarily as a result of headcount additions to support anticipated higher growth in certain segments and increased headcount related to the Valesta and HCP acquisitions, and an $11.8 million increase in bonuses and commissions as a result of increased revenue and the attainment of incentive compensation targets. Total SG&A expenses as a percentage of revenues decreased to 22.1 percent for 2012 compared with 25.7 percent in 2011. Excluding acquisition-related costs of $10.6 million, total SG&A expenses as a percentage of revenues was 21.2 percent for 2012. Amortization of Intangible Assets. Amortization of intangible assets was $18.0 million compared with $2.3 million in 2011. The $15.7 million increase was due to amortization related to $104.8 million of identifiable intangible assets acquired related to the Apex acquisition in May 2012. Apex's customer relationships were valued at $92.1 million and are being amortized using an accelerated method. Interest Expense. Interest expense was $17.8 million compared with $2.9 million in the same period in 2011. This increase was primarily due to higher debt outstanding for the new senior secured credit agreement closed in May 2012 to fund the cash portion of the acquisition of Apex. Provision for Income Taxes. The provision for income taxes was $32.3 million compared with $17.2 million for the same period in the prior year. The annual effective tax rate was 43.1 percent for 2012 and 41.4 percent for 2011. The increase in the annual effective tax rate in 2012 relates to the addition of Apex and their higher non-deductible expenses as well as valuation allowances on deferred tax assets of certain of our foreign subsidiaries. RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2011 COMPARED WITH THE YEAR ENDED DECEMBER 31, 2010 Revenues by segment (in thousands): Oxford (formerly IT and Engineering) Life Sciences Healthcare Physician Year Ended December 31, Change 2011 2010 $ % $ $ 266,742 $ 178,688 $ 155,324 94,598 80,617 109,495 76,287 73,595 88,054 45,829 18,311 7,022 597,281 $ 438,065 $ 159,216 49.3% 41.9% 24.0% 9.5% 36.3% Revenues increased $159.2 million, or 36.3 percent, mainly due to growth in all four segments which was partially due to our acquisitions of Cambridge, Sharpstream, Valesta and HCP. Cambridge and Sharpstream were acquired in 2010, Valesta was acquired during the first quarter of 2011 and HCP was acquired on July 31, 2011. Cambridge is reported under the Life Sciences, Oxford and Physician segments; Sharpstream and Valesta are reported under the Life Sciences segment and HCP is reported under the Physician segment. Consolidated revenues for the year ended December 31, 2011 included $48.1 million related to our Cambridge, Sharpstream, Valesta and HCP acquisitions compared with $9.9 million related to the Cambridge and Sharpstream acquisitions in 2010. Oxford segment revenues increased $88.1 million, or 49.3 percent, comprised of a 41.0 percent increase in the average number of contract professionals on assignment and a 5.8 percent increase in average bill rate. The increase in revenue was also due to a $0.9 million, or 46.4 percent increase in direct hire and conversion fee revenues. Oxford segment revenues for the year ended December 31, 2011 included $4.3 million in revenue from our Cambridge acquisition in April 2010, compared with $2.2 million in 2010. Because many of our placements 25 involve capital projects, we believe that one of the reasons the demand for our services has increased with the progressing economic recovery is that more companies have increased their capital spending. Life Sciences segment revenues increased $45.8 million, or 41.9 percent, comprised of a $42.4 million increase in staffing revenues and a $3.4 million, or 46.7 percent increase in direct hire and conversion fees. The increase in staffing revenues resulted from a 29.1 percent increase in the average number of contract professionals on assignment and a 7.8 percent increase in average bill rate. The year-over-year increase in revenues was primarily attributable to increased demand for our service offerings as our clients’ end markets have improved in 2011 with the progressing economic recovery and an increase in revenues of $24.8 million from the business acquired in 2010 and 2011. Revenues for our Healthcare segment (comprised of our Nurse Travel and Allied Healthcare lines of business) increased $18.3 million, or 24.0 percent. The increase in revenues in the Healthcare segment was attributable to improved economic trends in the healthcare sector, which contributed to the increase in the number of contract professionals on assignment, open orders and average bill rates and supporting customers who were undergoing system conversions. Although the Healthcare segment was soft, we continued to see signs of improvement in demand. Nurse Travel revenues increased $12.9 million, or 35.1 percent, to $49.6 million, comprised of a 29.5 percent increase in the average number of nurses on assignment and a 2.0 percent increase in the average bill rate. Revenues related to staffing resulting from labor disruptions at customer sites included $7.1 million in 2011 and $5.0 million in 2010. Allied Healthcare revenues increased $5.4 million, or 13.7 percent, to $45.0 million, comprised of a 5.9 percent increase in average number of contract professionals on assignment and a 2.5 percent increase in the average bill rate. The Allied Healthcare operating environment continued to demonstrate signs of improvement as economic trends in our end markets showed signs of stabilization and growth as evidenced by year-over-year growth in the number of contractors and clients on billing, average bill rate, permanent placement activity and billable hours. Physician segment revenues increased $7.0 million, or 9.5 percent, comprised of a 16.5 percent increase in the average number of physicians on assignment, a 1.9 percent decrease in average bill rate and a $0.3 million, or 8.5 percent decrease in direct hire and conversion fees revenue Physician segment revenues for year ended December 31, 2011 included $11.4 million related to our HCP and Cambridge acquisitions. The legacy physician staffing business decreased year over year. We attribute this to continued uncertainty related to healthcare reform, fewer physicians deciding to retire, current economic conditions and high unemployment which have reduced the number of elective procedures and lowered patient census at client facilities. Gross Profit and Gross Margins Gross Profit by segment (in thousands): Oxford (formerly IT and Engineering) Life Sciences Healthcare Physician Year Ended December 31, 2011 2010 Gross Profit Gross Margin Gross Profit Gross Margin $ 94,967 52,643 26,637 25,858 35.6% $ 33.9% 28.2% 32.1% 64,775 37,776 23,058 23,847 $ 200,105 33.5% $ 149,456 36.3% 34.5% 30.2% 32.4% 34.1% The year-over-year gross profit increase was primarily due to higher revenues, which was partially offset by a 62 basis point contraction in consolidated gross margin. The contraction in gross margin was primarily due to margin contraction in the Healthcare and Oxford segments. Oxford segment gross profit increased $30.2 million, or 46.6 percent, primarily due to an $88.1 million, or 49.3 percent, increase in revenues, partially offset by a 65 basis point contraction in gross margin. The contraction in gross margin was in part due to a $4.7 million, or 35.2 percent, increase in other employee expenses, and a benefit in 2010 from employment tax credits related to the HIRE Act, which expired on December 31, 2010, partially offset by a $0.9 million increase in direct hire and conversion fee revenues and a 5.0 percent increase in bill/ pay spread. Life Sciences segment gross profit increased $14.9 million, or 39.4 percent. The increase in gross profit was primarily due to a 41.9 percent increase in revenues, offset by a 61 basis point contraction in gross margin. The contraction in gross margin was mainly due to a benefit in 2010 from employment tax credits related to the HIRE Act, which expired on December 31, 2010, higher European payroll tax rates and holiday pay related to Valesta employees and an increase in unemployment insurance expenses. This contraction was partially offset by a $3.4 million increase in direct hire and conversion fee revenues mainly from our Sharpstream acquisition and an 11.4 percent increase in bill/pay spread. Healthcare segment gross profit increased $3.6 million, or 15.5 percent. The increase in gross profit was due to a 24.0 percent increase in revenues, partially offset by a 207 basis point contraction in gross margin. The contraction in gross margin was mainly due to an abnormally high gross margin in Nurse Travel in 2010, related to supporting a customer with labor disruptions when we did not have to have nurses travel. and thus the related costs, a $1.8 million increase in travel related expenses, a $1.9 million increase in other employee expenses, and a $0.7 million increase in unemployment insurance expense. The contraction in gross margin was partially offset by an 8.1 percent 26 increase in bill/pay spread. Within this segment, Allied Healthcare gross profit increased 11.0 percent while gross margin decreased 77 basis points and Nurse Travel gross profit increased 21.3 percent while gross margin decreased 283 basis points. Physician segment gross profit increased $2.0 million, or 8.4 percent. The increase in gross profit was due to a $7.0 million, or 9.5 percent, increase in revenues, partially offset by a 32 basis point contraction in gross margin. The contraction in gross margin was primarily due to a 7.0 percent decrease in bill/pay spread, in part a result of the acquisition of HCP which has a higher concentration of lower gross margin government business, and a $0.3 million, or 8.5 percent, decrease in direct hire revenue and conversion fee revenues, partially offset by a $1.5 million decrease in medical malpractice insurance expense primarily due to favorable claims development. Selling, General and Administrative Expenses. For the year ended December 31, 2011, SG&A expenses increased $24.9 million, or 19.0 percent, to $155.7 million in 2011. The increase in SG&A expenses was primarily due to a $20.1 million, or 21.1 percent, increase in compensation and benefits. The increase in compensation and benefits was due to (i) an $11.7 million increase in compensation expenses primarily as a result of increased headcount related to the Cambridge, Sharpstream, Valesta and HCP acquisitions and headcount additions to support anticipated high growth in certain segments, (ii) an $8.4 million increase in bonuses and commissions as a result of increased revenue and the anticipated attainment of incentive compensation targets, and (iii) a $0.5 million increase in acquisition costs primarily related to the recent acquisitions. Additionally, non-compensation and benefits related SG&A expenses increased $2.9 million as a result of the Valesta and HCP acquisitions which were both completed in 2011. This increase in SG&A expenses was partially offset by a $1.9 million gain related to the settlements of the Cambridge earn-out and Sharpstream earn-out. Total SG&A expenses as a percentage of revenues decreased to 26.1 percent for the year ended December 31, 2011 compared with 29.9 percent in the same period in 2010. Impairment of Goodwill. We recognized a goodwill impairment charge of $15.4 million related to Nurse Travel during 2010. The goodwill impairment charge for Nurse Travel was a result of the decreased fair value of the reporting unit due to lowered growth expectations in the later years because of uncertainty regarding the timing of the recovery of the Nurse Travel industry. Interest Expense. Interest expense was $3.0 million for the year ended December 31, 2011 compared with $8.3 million in 2010. This decrease was related to the $2.8 million write-off of unamortized capitalized loan costs in 2010, related to the old borrowing facility that was paid in full in December 2010, as well as lower interest rates in 2011. Provision for Income Taxes. The provision for income taxes was $17.2 million for the year ended December 31, 2011 compared with $5.0 million in 2010. The annual effective tax rate was 41.4 percent for the year ended December 31, 2011 and 47.4 percent in 2010 excluding the impact of the goodwill impairment charge. The decrease in the tax rate in 2011 was primarily related to the year-over-year increase in income before income taxes for 2011 while permanent differences increased, but not as much as the increase to the income before income taxes, which lowered the annual effective rate. Refer to Note 9 - Income Taxes for detailed information reconciling the statutory tax rate to the effective tax rate. Liquidity and Capital Resources Our working capital at December 31, 2012 was $175.0 million and our cash and cash equivalents were $27.5 million, of which $8.0 million was held in foreign countries. Cash held in foreign countries is not available to fund domestic operations unless repatriated, which would require the accrual and payment of taxes. We do not intend to repatriate cash held in foreign countries. Our operating cash flows have been our primary source of liquidity and historically have been sufficient to fund our working capital and capital expenditure needs. Our working capital requirements consist primarily of the financing of accounts receivable, payroll expenses and the periodic payments of principal and interest on our loans. Net cash provided by operating activities was $40.7 million for 2012 compared with $23.4 million for 2011. Cash provided by operating activities in 2012 was primarily driven by income from operations offset by an increase working capital (excluding cash) related to the high growth of the business. Cash provided by operating activities in 2011 was primarily driven by income from operations, an increase in accrued payroll and contract professional pay, offset by an increase in accounts receivable. Net cash used in investing activities was $363.0 million during 2012 compared with $41.1 million during 2011. Cash paid for acquisitions was $347.7 million and capital expenditures for information technology projects, leasehold improvements and various property and equipment purchases increased $5.9 million to $14.4 million in 2012. We estimate that capital expenditures for 2013 will be approximately $16.0 million. Net cash provided by financing activities was $331.9 million for 2012, compared with $17.5 million provided by financing activities in 2011. During 2012, principal payments of long-term debt were $173.2 million, versus $20.5 million paid down during 2011. Proceeds from new borrowings on the term loan and line of credit were $513.0 million and $40.5 million in 2012 and 2011, respectively. Under terms of the credit facility, the term loan facility is repayable at the minimum rate of $2.5 million per quarter and we are required to reduce the term loan by up to 50 percent of our excess cash flow based on leverage ratios, as defined by the agreement for each year end over the next seven years. We are required to maintain certain financial covenants, including a maximum leverage ratio. Our leverage ratio (consolidated funded debt to trailing 12 months EBITDA) is currently limited to no more than 4.25 to 1.00 and reduces over time to 3.00 to1.00. As of December 31, 2012, the leverage ratio was approximately 2.73 to 1.00 and we were in compliance with all such covenants. Additionally, the agreement, which is secured by substantially all of our assets, provides for certain limitations on our ability to, 27 among other things, incur additional debt, offer loans, and declare dividends. As of December 31, 2012, we had $72.2 million of borrowing available under our credit facility. We continue to make progress on enhancements to our front-office and back-office information systems. These enhancements include the consolidation of back-office systems across all corporate functions, as well as enhancements to and broader application of our front-office software across all lines of business. We believe that our working capital as of December 31, 2012, our credit facility and expected operating cash flows will be sufficient to fund future requirements of our debt repayment obligations, accounts payable and related payroll expenses, as well as capital expenditure initiatives for the next twelve months. Commitments and Contingencies We lease space for our corporate and branch offices. Rent expense was $14.1 million in 2012, $8.6 million in 2011 and $8.4 million in 2010. The following table sets forth, on an aggregate basis, at December 31, 2012, the amounts of specified contractual cash obligations required to be paid in the periods shown (in thousands): 2013 2014 2015 2016 2017 Thereafter Total Long-term debt obligations $ 10,000 $ 10,000 $ 10,000 $ 10,000 $ 52,500 $ 334,088 $ 426,588 Operating lease obligations Related party leases 13,545 1,266 11,117 1,299 9,210 1,168 6,386 694 3,588 175 6,764 — 50,610 4,602 Total $ 24,811 $ 22,416 $ 20,378 $ 17,080 $ 56,263 $ 340,852 $ 481,800 For additional information about these contractual cash obligations, see Note 8 - Commitments and Contingencies to our Consolidated Financial Statements appearing in Part II, Item 8 of this report. Interest payments related to our bank debt are not set forth in the table above. We have large retention policies for our workers' compensation and medical malpractice exposures. In connection with this program, we pay a base premium plus actual losses incurred up to certain levels and are insured for losses greater than certain levels per occurrence and in the aggregate. The workers' compensation and medical malpractice loss reserves liability is determined based on claims filed and claims incurred but not yet reported. We account for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates, differences in estimates and actual payments for claims are recognized in the period that the estimates changed or payments were made. The workers' compensation and medical malpractice loss reserves liability was $10.3 million and $10.4 million at December 31, 2012 and 2011, respectively. Additionally, we have unused stand-by letters of credit outstanding to secure obligations for workers’ compensation claims with various insurance carriers. The unused stand-by letters of credit at December 31, 2012 and 2011 were $2.8 million and $2.4 million, respectively. As of December 31, 2012 and 2011, we have an income tax reserve in other long-term liabilities related to our uncertain tax positions of $0.4 million and $0.3 million, respectively. We are involved in various other legal proceedings, claims and litigation arising in the ordinary course of business. However, based on the facts currently available, we do not believe that the disposition of matters that are pending or asserted will have a material effect on our consolidated financial statements. We are subject to earn-out obligations entered into in connection with acquisitions. If the acquired businesses meet predetermined targets, we are obligated to make additional cash payments in accordance with the terms of such earn-out obligations. At December 31, 2012, the Company has potential future earn-out obligations of approximately $9.1 million through 2013. Off-Balance Sheet Arrangements As of December 31, 2012, the Company had no significant off-balance sheet arrangements other than operating leases and unused stand-by letters of credit outstanding. Accounting Standards Updates See Note 1 - Summary of Significant Accounting Policies, to the Consolidated Financial Statements in Part II, Item 8 of this report for a discussion of new accounting pronouncements. 28 Critical Accounting Policies Our accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements in Part II, Item 8 of this report. We prepare our financial statements in conformity with accounting principles generally accepted in the United States, which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates. We consider the following policies to be most critical in understanding the judgments that are involved in preparing our financial statements and the uncertainties that could impact our results of operations, financial condition and cash flows. Allowance for Doubtful Accounts and Billing Adjustments. We estimate an allowance for doubtful accounts, as well as an allowance for billing adjustments related to trade receivables based on our analysis of historical collection and adjustment experience. We apply bad debt percentages based on experience to the outstanding accounts receivable balances at the end of the period, as well as analyze specific reserves as needed. Impaired receivables, or portions thereof, are charged off when deemed uncollectible. If we experience a significant change in collections or billing adjustment experience, our estimates of the recoverability of accounts receivable could change by a material amount. Workers’ Compensation and Medical Malpractice Loss Reserves. We carry retention policies for our workers’ compensation and medical malpractice exposures. In connection with these programs, we pay a base premium plus actual losses incurred, not to exceed certain stop-loss limits. We are insured for losses above these limits, both per occurrence and in the aggregate. The workers' compensation and medical malpractice loss reserves are based upon an actuarial report obtained from a third party and determined based on claims filed and claims incurred but not reported. We account for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates and differences in estimates and actual payments for claims are recognized in the period that the estimates changed or the payments were made. Contingencies. We record an estimated loss from a loss contingency when information available prior to issuance of our financial statements indicates it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements, and the amount of the loss can be reasonably estimated. Accounting for contingencies, such as legal settlements, workers’ compensation matters and medical malpractice insurance matters, requires us to use our judgment. While we believe that our accruals for these matters are adequate, if the actual loss from a loss contingency is significantly different than the estimated loss, results of operations may be over or understated. Income taxes. We account for income taxes using the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. We make a comprehensive review of our uncertain tax positions regularly. In this regard, an uncertain tax position represents our expected treatment of a tax position taken in a filed return, or planned to be taken in a future tax return or claim that has not been reflected in measuring income tax expense for financial reporting purposes. In general, until these positions are sustained by the taxing authorities or statutes expire for the year that the position was taken, we do not recognize the tax benefits resulting from such positions and report the tax effects as a liability for uncertain tax positions in our consolidated balance sheets. Goodwill and Identifiable Intangible Assets. Goodwill and intangible assets with indefinite lives are tested for impairment on an annual basis as of October 31, and for goodwill whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount and for indefinite lived intangibles, if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. During the quarter ended December 31, 2012, we changed the date of the annual impairment test for goodwill from December 31 to October 31. The change is preferable because it alleviates constraints on accounting resources during the year-end reporting process and better aligns the timing of the assessment with our planning and forecasting process, which occurs primarily in the third quarter. The resulting change in accounting principle related to changing the annual goodwill impairment test date did not delay, accelerate or avoid an impairment charge. Due to significant judgments and estimates that are utilized in the goodwill impairment analysis, we determined it was impracticable to objectively determine, without the use of hindsight, projected cash flows and related valuation estimates as of each October 31 for periods prior to October 31, 2012. As such, we have prospectively applied the change in the annual goodwill impairment test date from October 31, 2012. Intangible assets with indefinite lives consist of trademarks. We test trademarks for impairment on an annual basis, on October 31. In order to test the trademarks for impairment, we determine the fair value of the trademarks and compare such amount to its carrying value. We determine the fair value of the trademarks using a projected discounted cash flow analysis based on the relief-from-royalty approach. The principal factors used in the discounted cash flow analysis requiring judgment are projected net sales, discount rate, royalty rate and terminal value assumption. The royalty rate used in the analysis is based on transactions that have occurred in our industry. Intangible assets having finite lives are amortized over their useful lives and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Customer relations are amortized using an accelerated method. Contractor relations and non- 29 compete agreements are amortized using the straight-line method. Other than the goodwill impairment in 2010 discussed below, we did not have any impairment of indefinite lived or finite lived intangibles in 2012, 2011, or 2010. Goodwill is tested for impairment using a two-step process in which the first step compares the fair value of a reporting unit, which is generally an operating segment or one level below the operating segment level which is a business and for which discrete financial information is available and reviewed by segment management, to the reporting unit's carrying value. We determine the fair value of each reporting unit based upon a weighted average calculation using the fair value derived from a discounted cash flow analysis and a market approach analysis. Discounted cash flows are developed for each reporting unit based on assumptions including revenue growth expectations, gross margins, operating expense projections, working capital, capital expense requirements and tax rates. The multi-year financial forecasts for each reporting unit used in the cash flow models considered several key business drivers such as new product lines, historical performance and industry and economic trends, among other considerations. The market approach considers multiples of financial metrics, primarily EBITDA, based on trading multiples of a group of guideline public companies in the staffing industry, which multiples are then applied to the corresponding financial metrics of our reporting units to derive an indication of fair value. If after performing the first step of the goodwill impairment test, the fair value of the reporting unit does not exceed its carrying value, we perform a second step of the goodwill impairment test for that reporting unit. The second step measures the amount of goodwill impairment by comparing the implied fair value of the respective reporting unit goodwill with the carrying value of that goodwill. The implied fair value of goodwill is determined under the same approach utilized to estimate the amount of goodwill recognized in a business combination. This approach requires we allocate the fair value of the respective reporting unit as calculated in the first step of the goodwill impairment test to the reporting unit assets, including identifiable intangible assets, which typically includes tradenames, staffing databases and customer relationships, and reporting unit liabilities, based on the estimated fair values of such assets and liabilities, with any excess reporting unit fair value representing the implied fair value of goodwill for that reporting unit. The reporting unit goodwill impairment loss, if any, is measured as the amount by which the carrying value of goodwill exceeds the implied fair value of goodwill calculated in the second step of the goodwill impairment test. The principal factors used in the discounted cash flow analysis requiring judgment are the projected results of operations, discount rate, and terminal value assumptions. The discount rate is determined using the weighted average cost of capital (WACC). The WACC takes into account the relative weights of each component of an average market participant's capital structure (equity and debt). It also considers our risk-free rate of return, equity market risk premium, beta and size premium adjustment. A range of discount rates are utilized across the reporting units based on the entity size of each reporting unit. The terminal value assumptions are applied subsequent to the tenth year of the discounted cash flow model. We performed step one goodwill impairment tests for each reporting unit as of October 31, 2012 as this is our new annual impairment test date. No impairment charge was recorded for any of the reporting units as of October 31, 2012. The fair value of all reporting units exceeded their respective carrying values by approximately 21 percent or more. The discount rate used in the cash flow analysis ranged between approximately 13 to 15 percent. Based upon the annual goodwill impairment test in 2011, there was no goodwill impairment charge. We recognized a goodwill impairment charge of $15.4 million in the fourth quarter of 2010. Goodwill for the Company's impaired reporting unit, Nurse Travel, with a carrying amount of $15.4 million was written down to the implied fair value of $0 resulting in an impairment charge of $15.4 million. The discounted cash flows and the resulting fair value estimates of our reporting units are sensitive to changes in assumptions. An increase of less than eight percent in the discount rate of a reporting unit could cause the fair value of certain significant reporting units to be below their carrying value. Changes in the timing of the recovery and the impact on our operations and costs may also affect the sensitivity of the projections including achieving future cost savings resulting from initiatives which contemplate further synergies from system and operational improvements in infrastructure and field support which were included in our forecasts. Ultimately, future changes in these assumptions may impact the estimated fair value of a reporting unit and cause the fair value of the reporting unit to be below its carrying value, which would require a step two analysis and may result in impairment of goodwill. Due to the many variables inherent in the estimation of a reporting unit's fair value and the relative size of recorded goodwill, changes in assumptions may have a material effect on the results of our impairment analysis. Downward revisions of our forecasts, extended delays in the economic recovery, or a sustained decline of our stock price resulting in market capitalization significantly below book value could lead to an impairment of goodwill or intangible assets with indefinite lives in future periods. Impairment or Disposal of Long-Lived Assets. We evaluate long-lived assets, other than goodwill and identifiable intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss is recognized when the sum of the undiscounted future cash flows is less than the carrying amount of the asset, in which case a write-down is recorded to reduce the related asset to its estimated fair value. There was no impairment of long-lived assets as of December 31, 2012, 2011 or 2010. Business Combinations. The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. We determine the estimated fair values after review and consideration of relevant information including discounted cash flows, quoted market prices and estimates made by management. Accordingly, these can be affected by contract performance and other factors over time, which may cause final amounts to 30 differ materially from original estimates. We adjust the preliminary purchase price allocation, as necessary, up to one year after the acquisition closing date if we obtain more information regarding asset valuations and liabilities assumed. Goodwill acquired in business combinations is assigned to the reporting unit(s) expected to benefit from the combination as of the acquisition date. Acquisition related costs are recognized separately from the acquisition and are expensed as incurred. Stock-Based Compensation. We record compensation expense for restricted stock awards and stock units based on the fair market value of the awards on the date of grant. Market-based awards, which are based on achievement of targets indexed to our share price, are valued using a Monte Carlo simulation model. Compensation expense for performance-based awards is measured based on the amount of shares ultimately expected to vest, estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. We account for stock options granted and ESPP shares based on an estimated fair market value using a Black-Scholes option valuation model. This methodology requires the use of subjective assumptions, including expected stock price volatility and the estimated life of each award. The fair value of equity-based compensation awards less the estimated forfeitures is amortized over the service period of the award. Item 7A. Quantitative and Qualitative Disclosures about Market Risk We are exposed to certain market risks arising from transactions in the normal course of business, principally risks associated with foreign currency fluctuations and interest rates. We are exposed to foreign currency risk from the translation of foreign operations into U.S. dollars. Based on the relative size and nature of our foreign operations, we do not believe that a ten percent change in the value of foreign currencies relative to the U.S. dollar would have a material impact on our financial statements. Our primary exposure to market risk is interest rate risk associated with our debt instruments. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further description of our debt instruments. On February 18, 2011, we entered into an interest rate swap agreement to hedge a portion of our interest rate exposure on our senior secured credit agreement. The swap has a notional amount of $25.0 million and fixes a portion of our base borrowing rate, which is a floating rate based on a LIBOR swap rate that resets periodically. Effective August 8, 2012, the Company entered into three interest rate cap agreements to hedge a portion of its interest rate exposure on its senior secured debt (collectively referred to as the Interest Rate Caps). Under the terms of the Interest Rate Caps, the one month LIBOR rate will not exceed 3.0 percent. From a practical standpoint, the interest rate in the hedged portion of the debt is limited to a maximum of 3.0 percent plus the Eurodollar applicable margin. The total initial notional amount was $223.1 million and is scheduled to decline over the term of the Interest Rate Caps. Each of the Interest Rate Caps terminates on August 10, 2015. As of December 31, 2012, we had $426.6 million outstanding under the senior secured credit agreement, $401.6 million of which bears interest at variable-rates. We have the option to determine the variable interest rate as the Eurodollar rate or the base rate (which is the highest of the bank’s prime rate, one-half of 1.0 percent in excess of the overnight federal funds rate, and 1.0 percent in excess of the one- month Eurodollar rate), plus in each case, an applicable margin. Excluding the effect of our interest rate swap agreement and interest rate caps, a hypothetical 1.0 percent change in interest rates on variable rate debt would have resulted in interest expense fluctuating approximately $4.3 million based on $426.6 million of debt outstanding for any twelve month period. Including the effect of our interest rate swap agreement and interest rate cap agreements, a 1.0 percent change in interest rates on variable debt would have resulted in interest expense fluctuating approximately $4.0 million based on $401.6 million of debt outstanding for any twelve month period. We have not entered into any market risk sensitive instruments for trading purposes. 31 Item 8. Financial Statements and Supplementary Data REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of On Assignment, Inc. Calabasas, California We have audited the accompanying consolidated balance sheets of On Assignment, Inc. and subsidiaries (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of operations and comprehensive income (loss), stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2012. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of On Assignment, Inc. and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. As discussed in Note 4 to the consolidated financial statements, on May 15, 2012, the Company acquired all the outstanding shares of Apex Systems, Inc. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 18, 2013 expressed an unqualified opinion on the Company's internal control over financial reporting. /s/ Deloitte & Touche LLP Los Angeles, California March 18, 2013 32 ON ASSIGNMENT, INC.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Summary of Significant Accounting Policies. Principles of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition. Revenues from contract assignments, net of sales adjustments and discounts, are recognized when earned, based on hours worked by the Company’s contract professionals on a weekly basis. Conversion and direct hire fees are recognized when employment candidates begin permanent employment. The Company records a sales allowance against consolidated revenues, which is an estimate based on historical billing adjustment experience. The sales allowance is recorded as a reduction to revenues and an increase to the allowance for billing adjustments. The billing adjustment reserve includes an allowance for fallouts. Fallouts are direct hire and conversion fees that do not complete the contingency period, which is typically 90 days or less. The Company includes reimbursed expenses, in revenues and the associated amounts of reimbursable expenses in cost of services. The Company records revenues on a gross basis as a principal or on a net basis as an agent depending on the arrangement. The key indicators as to whether it acts as a principal or an agent are whether the Company (i) has the direct contractual relationships with its customers, (ii) bears the risks and rewards of the transactions, and (iii) has the discretion to select the contract professionals and establish their price. Income Taxes. Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. The Company makes a comprehensive review of its uncertain tax positions regularly. An uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed return, or planned to be taken in a future tax return or claim that has not been reflected in measuring income tax expense for financial reporting purposes. In general, until these positions are sustained by the taxing authorities or statutes expire for the year that the position was taken, the Company does not recognize the tax benefits resulting from such positions and reports the tax effects as a liability for uncertain tax positions. Foreign Currency Translation. The functional currency of the Company’s foreign operations is their local currency, and as such, their assets and liabilities are translated into U.S. dollars at the rate of exchange in effect on the balance sheet date. Revenue and expenses are translated at the average rates of exchange prevailing during each monthly period. The related translation adjustments are recorded as cumulative foreign currency translation adjustments in accumulated other comprehensive income as a separate component of stockholders’ equity. Gains and losses resulting from foreign currency transactions, which are not material, are included in Selling, general and administrative (SG&A) expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss). Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity of three months or less on the date of purchase to be cash equivalents. Allowance for Doubtful Accounts and Billing Adjustments. The Company estimates an allowance for doubtful accounts and an allowance for billing adjustments related to trade receivables based on an analysis of historical collection and billing adjustment experience. The Company applies bad debt percentages based on experience to the outstanding accounts receivable balances at the end of the period, as well as analyzes specific reserves as needed. Impaired receivables, or portions thereof, are written-off when deemed uncollectible. Property and Equipment. Property and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets, generally three to five years. Leasehold improvements are amortized over the shorter of the life of the related asset or the remaining term of the lease. Costs associated with customized internal-use software systems that have reached the application development stage and meet recoverability tests are capitalized. Such capitalized costs include external direct costs utilized in developing or obtaining the applications and payroll and payroll-related expenses for employees who are directly associated with the application development. Goodwill and Identifiable Intangible Assets. Goodwill and intangible assets with indefinite lives are tested for impairment on an annual basis as of October 31, and for goodwill whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount and for indefinite lived intangibles, if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. 38 During the quarter ended December 31, 2012, the Company changed the date of the annual impairment test for goodwill from December 31 to October 31. The change is preferable because it alleviates constraints on accounting resources during the year-end financial statement close and reporting process and better aligns the timing of the assessment with our planning and forecasting process, which occurs primarily in the third quarter. The change in accounting principle related to the annual goodwill impairment test date did not delay, accelerate or avoid an impairment charge. Due to significant judgments and estimates that are utilized in the goodwill impairment analysis, the Company determined it was impracticable to objectively determine, without the use of hindsight, projected cash flows and related valuation estimates as of each October 31 for periods prior to October 31, 2012. As such, the Company has prospectively applied the change in the annual goodwill impairment test date from October 31, 2012. Intangible assets with indefinite lives consist of trademarks. The Company tests trademarks for impairment on an annual basis, on October 31. In order to test the trademarks for impairment, the Company determines the fair value of the trademarks and compares such amount to its carrying value. The fair value of the trademarks is determined using a projected discounted cash flow analysis based on the relief-from-royalty approach. The principal factors used in the discounted cash flow analysis requiring judgment are projected net sales, discount rate, royalty rate and terminal value assumption. The royalty rate used in the analysis is based on transactions that have occurred in our industry. Intangible assets having finite lives are amortized over their useful lives and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Customer relations are amortized using an accelerated method. Contractor relations and non-compete agreements are amortized using the straight-line method. Other than the goodwill impairment in 2010 discussed below, we did not have any impairment of indefinite lived or finite lived intangibles in 2012, 2011, or 2010. Goodwill is tested for impairment using a two-step process in which the first step compares the fair value of a reporting unit, which is generally an operating segment or one level below the operating segment level, which is a business and for which discrete financial information is available and reviewed by segment management, to the reporting unit's carrying value. The second step measures the amount of impairment by comparing the implied fair value of the respective reporting unit's goodwill with the carrying value of that goodwill. The goodwill impairment loss is measured by the amount the carrying value of goodwill exceeds the implied fair value of goodwill. The Company performed the step one goodwill impairment tests for each reporting unit as of October 31, 2012 as this is the annual impairment test date. No impairment charge was recorded for any of the reporting units as of October 31, 2012. Based upon the annual goodwill impairment test in 2011, there was no goodwill impairment charge. The Company recognized a goodwill impairment charge of $15.4 million in the fourth quarter of 2010. Goodwill for the Company's impaired reporting unit, Nurse Travel, with a carrying amount of $15.4 million was written down to the implied fair value of $0 resulting in an impairment charge of $15.4 million. Impairment or Disposal of Long-Lived Assets. The Company evaluates long-lived assets, other than goodwill and identifiable intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss is recognized when the sum of the undiscounted future cash flows is less than the carrying amount of the asset, in which case a write-down is recorded to reduce the related asset to its estimated fair value. Workers’ Compensation and Medical Malpractice Loss Reserves. The Company carries retention policies for its workers’ compensation liability and medical malpractice liability exposures. In connection with these programs, the Company pays a base premium plus actual losses incurred, not to exceed certain stop-loss limits. The Company is insured for losses above these limits, both per occurrence and in the aggregate. The workers' compensation and medical malpractice loss reserves are based upon an actuarial report obtained from a third party and determined based on claims filed and claims incurred but not reported. The Company accounts for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates and differences in estimates and actual payments for claims are recognized in the period that the estimates changed or the payments were made. Contingencies. The Company records an estimated loss from a loss contingency when information available prior to issuance of its financial statements indicates it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements, and the amount of the loss can be reasonably estimated. Accounting for contingencies, such as legal settlements, workers’ compensation matters and medical malpractice insurance matters, requires the Company to use judgment. Business Combinations. The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. The Company determines the estimated fair values after review and consideration of relevant information including discounted cash flows, quoted market prices and estimates made by management. Accordingly, these can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates. The Company adjusts the preliminary purchase price allocation, as necessary, up to one year after the acquisition closing date if it obtains more information regarding asset valuations and liabilities assumed. Goodwill acquired in business combinations is assigned to the reporting unit(s) expected to benefit from the combination as of the acquisition date. Acquisition related costs are recognized separately from the acquisition and are expensed as incurred. Stock-Based Compensation. The Company records compensation expense for restricted stock awards and stock units based on the fair market value of the awards on the date of grant. Market-based awards, which are based on achievement of targets indexed to the Company’s share price, are valued using a Monte Carlo simulation model. Compensation expense for performance-based awards is measured based on the amount of shares ultimately expected to vest, estimated at each reporting date based on management’s expectations regarding the relevant 39 performance criteria. The Company accounts for stock options granted and ESPP shares based on an estimated fair market value using a Black-Scholes option valuation model. This methodology requires the use of subjective assumptions including expected stock price volatility and the estimated life of each award. The fair value of equity-based compensation awards less the estimated forfeitures is amortized over the vesting period of the award. Concentration of Credit Risk. Financial instruments that potentially subject the Company to credit risks consist primarily of cash, cash equivalents and trade receivables. The Company places its cash and cash equivalents in low risk investments with quality credit institutions and limits the amount of credit exposure with any single institution above FDIC insured limits. Concentration of credit risk with respect to accounts receivable is limited because of the large number of geographically dispersed customers, thus spreading the trade credit risk. The Company performs ongoing credit evaluations to identify risks and maintains an allowance to address these risks. Derivative Instruments. The Company utilizes derivative financial instruments to manage interest rate risk. The Company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. Advertising Costs. Advertising costs, which are expensed as incurred, were $5.3 million in 2012, $3.2 million in 2011, and $3.1 million in 2010. 2. Accounting Standards Updates. In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (ASU 2013-02). Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income (AOCI) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective for us on January 1, 2013. In July 2012, the FASB issued Accounting Standards Update No. 2012-02, Intangibles-Goodwill and Other (Topic 350) — Testing Indefinite-Lived Intangible Assets for Impairment (ASU 2012-02), allowing entities the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. If the qualitative assessment indicates it is more-likely-than-not that the fair value of an indefinite lived intangible asset is less than its carrying amount, the quantitative impairment test is required. Otherwise, no testing is required. ASU 2012-02 is effective for the Company in the period beginning January 1, 2013. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. In December 2011, the FASB issued FASB ASU No. 2011-11, Balance Sheet (Topic 210)—Disclosures about Offsetting Assets and Liabilities. ASU 2011-11 requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Entities are required to disclose both gross and net information about these instruments. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. In September 2011, the FASB issued ASU No. 2011-08, Testing Goodwill for Impairment (Topic 350) — Intangibles—Goodwill and Other (ASU 2011-08), to allow entities to use a qualitative approach to test goodwill for impairment. ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If so, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two step goodwill impairment test is not required. ASU 2011-08 was effective for the Company in the first quarter of fiscal 2012 and earlier adoption was permitted. The adoption of ASU 2011-08 did not have a material impact on the consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income (Topic 220) — Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 was effective for the Company in the first quarter of fiscal 2012 and was applied retrospectively. In December 2011, the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05, which defers certain aspects of ASU 2011-05 related to the presentation of reclassification adjustments. The adoption of ASU 2011-05 only impacted the presentation of the consolidated financial statements. In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820) — Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. ASU 2011-04 became effective for the Company in the first quarter of fiscal 2012; see Note 14 - Fair Value Measurements for required disclosures. 40 3. Property and Equipment. Property and equipment at December 31, 2012 and 2011 consisted of the following (in thousands): Furniture, fixtures and equipment Computers and related equipment Computer software Leasehold improvements Work-in-progress Less -- accumulated depreciation and amortization 2012 2011 $ 6,891 $ 6,918 32,871 5,417 9,937 62,034 (35,172) 5,776 5,414 27,306 4,633 4,751 47,880 (29,823) $ 26,862 $ 18,057 Depreciation and amortization expense related to property and equipment was $6.7 million in 2012, $6.5 million in 2011 and $5.9 million in 2010. The Company has capitalized costs related to its various technology initiatives. The net book value of the property and equipment related to software development was $12.1 million as of December 31, 2012 and $8.5 million as of December 31, 2011, which includes work- in-progress of $7.5 million and $3.9 million, respectively. 4. Acquisitions. On May 15, 2012, the Company acquired all of the outstanding shares of Apex Systems, Inc., a privately-owned provider of information technology staffing headquartered in Richmond, Virginia. The primary reason for the acquisition was to expand the Company's information technology staffing services. The purchase price totaled approximately $610.8 million, comprised of $385.0 million paid in cash at closing, $0.3 million paid in the third quarter related to the net working capital adjustments, and 14.3 million shares of common stock of the Company issued to the holders of shares of common stock and options to purchase common stock of Apex immediately prior to the effective time of the merger. Acquisition costs related to this transaction totaled approximately $9.8 million and were expensed in 2012. Goodwill and the identifiable intangible assets are deductible for tax purposes. The results of operations of Apex have been combined with those of the Company since the acquisition date. Apex revenues and net loss included in the Statement of Operations for the year-ended December 31, 2012 were $508.7 million and $(7.3) million, respectively. On July 31, 2011, the Company acquired all of the outstanding shares of HealthCare Partners, Inc. (HCP), a privately-owned provider of physician staffing headquartered in Atlanta, Georgia. The primary reasons for the acquisition were to expand the Physician segment business operations geographic coverage and to leverage the Company’s infrastructure. The purchase price for HCP was approximately $19.1 million comprised of $15.7 million in cash paid at closing and potential future earn-out consideration of $3.4 million (the maximum earn-out opportunity is capped at $3.7 million) based on estimated financial performance of HCP through 2013. Acquisition costs of approximately $57,000 were expensed in 2011. The Company discontinued the use of the HCP tradename during 2012. Goodwill is deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date. On February 28, 2011, the Company acquired all of the outstanding shares of Warphi N.V. and its subsidiaries (collectively, Valesta), a privately-owned provider of specialized clinical research staffing headquartered in Belgium. The primary reasons for the acquisition were to expand the Life Sciences business operations and to leverage the Company’s infrastructure. The purchase price for Valesta totaled $23.7 million, comprised of $16.8 million in cash paid at closing and potential future earn-out consideration of $6.9 million (the maximum earn-out is capped at a Euro value of €5.0 million or approximately $6.6 million at December 31, 2012 exchange rates) based on estimated financial performance of Valesta through 2013. Acquisition costs of approximately $0.4 million were expensed in 2011. Goodwill is not deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date. On July 19, 2010, the Company acquired all of the outstanding shares of Sharpstream Holdings Limited (Sharpstream), a privately- owned provider of search services for executives to middle managers in the life sciences sector. The primary reasons for the Sharpstream acquisition were to expand our Life Sciences business operations, further expand our global presence and to leverage the Company’s infrastructure. The purchase price totaled $8.6 million, comprised of $7.2 million in cash paid at closing, plus potential future earn-out consideration of up to $1.4 million. Acquisition costs of $0.1 million related to the purchase were expensed in 2010. Goodwill is not deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date. On April 16, 2010, the Company acquired all of the outstanding shares of The Cambridge Group Ltd. and Cambridge Contract Staffing Group, Inc. (Cambridge), a Connecticut-based privately-held provider of specialized staffing services. The primary reasons for the Cambridge acquisition were to expand our Life Sciences, Oxford, and Physician business operations and to leverage the Company’s infrastructure. The purchase price totaled $7.6 million, comprised of $5.3 million in cash paid at closing, plus potential future earn-out 41 consideration of up to $2.3 million. Acquisition costs of $0.1 million related to the purchase were expensed in 2010. Goodwill is not deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date. Assets and liabilities of the acquired companies were recorded at their estimated fair values at the dates of acquisition. The excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired has been allocated to goodwill. The fair value assigned to identifiable intangible assets was determined primarily by using a discounted cash flow method. The Company's allocation for the purchase price for Apex, except for the pre-acquisition contingencies and income taxes related to the acquisition, have been finalized. Any material measurement period adjustments will be recorded retrospectively to the acquisition date. During 2012, the Company adjusted Valesta's purchase price allocation. The adjustment was to correct the tax impact of the amortization of identifiable intangible assets. The adjustment was not material and had no impact on the consolidated statements of operations and comprehensive income (loss); accordingly it was not presented retrospectively. The fair value of earn-out obligations was based on the present value of the expected future payments to be made to the sellers of the acquired businesses in accordance with the respective purchase agreements. See Note - 14 Fair Value Measurements for further information regarding the fair value of earn-outs and the level 3 rollforward disclosure. The following tables summarize (in thousands) the purchase price allocations for the acquisitions of Apex, which is subject to finalization during the measurement period and HCP and Valesta: 2012 Acquisition 2011 Acquisitions Apex HCP Valesta Total Current assets Property and equipment Goodwill Identifiable intangible assets Other Total assets acquired Current liabilities Other Total liabilities assumed Total purchase price $ 169,844 $ 3,950 $ 902 266,788 251,555 494 689,583 77,905 850 78,755 123 14,398 1,784 13 20,268 1,070 49 1,119 $ $ $ $ 6,332 299 17,911 5,679 26 30,247 4,774 1,814 6,588 $ 10,282 422 32,309 7,463 39 50,515 5,844 1,863 7,707 $ $ 610,828 $ 19,149 $ 23,659 $ 42,808 $ $ $ The following table summarizes (in thousands) the allocation of the purchase price among the identifiable intangible assets for the acquisition of Apex, HCP and Valesta: Contractor relations Customer relations Non-compete agreements Trademarks Useful life 2 – 5 years 2 – 10 years 2 – 7 years indefinite Identifiable Intangible Asset Value 2012 Acquisition Apex HCP 2011 Acquisitions Valesta Total $ $ 10,589 92,147 2,076 146,743 251,555 $ $ 814 950 20 — 1,784 $ $ 266 2,395 440 2,578 5,679 $ $ 1,080 3,345 460 2,578 7,463 The summary below (in thousands, except for per share data) presents pro forma consolidated results of operations for the years ended December 31, 2012 and 2011 as if the acquisitions of HCP and Valesta occurred on January 1, 2010, and the acquisition of Apex occurred on January 1, 2011. The acquisitions in 2010 were not material to the Company, therefore pro forma information related to these acquisitions has not been presented. The pro forma financial information gives effect to certain adjustments, including: the amortization of intangible assets and interest expense on acquisition-related debt, changes in the management fees, and increased number of common shares as a result of the acquisition. Acquisition-related costs are assumed to have occurred at the beginning of the year prior to acquisition. The pro forma financial information is not necessarily indicative of the operating results that would have occurred if the acquisition had been consummated as of the date indicated, nor are they necessarily indicative of future operating results. 42 Revenues Operating income Net income Basic earnings per share Diluted earnings per share Weighted average number of shares outstanding Weighted average number of shares and dilutive shares outstanding $ $ $ $ $ 2012 2011 (unaudited) $ $ $ $ $ 1,521,982 121,565 55,615 1.07 1.05 52,103 53,190 1,316,165 68,608 26,109 0.51 0.50 51,180 52,062 5. Long-Term Debt. Long-term debt at December 31, 2012 and 2011 consisted of the following (in thousands): 2012 2011 New Senior Secured Debt -- $100 million term A loan facility, due May 2017 $ 92,500 $ $365 million term B loan facility, due May 2019 $75 million revolving credit facility, due May 2017 Old Senior Secured Debt (repaid May 2012) -- $75 million revolving credit facility $50 million term loan facility 334,088 — — — $ 426,588 $ — — — 43,000 43,750 86,750 On May 15, 2012, in connection with the Apex acquisition, the Company entered into a new senior secured credit agreement. The new credit agreement consists of (i) a $100.0 million, five-year term loan A facility, (ii) a $365.0 million, seven-year term loan B facility and (iii) a $75.0 million, five-year revolving loan facility with a $15.0 million sublimit for letters of credit. The new credit agreement also provides the ability to increase the loan facilities for up to $75.0 million in additional principal amount of revolving or term B loans, subject to receipt of lender commitments and satisfaction of specified conditions. Borrowings under the new credit agreement bear interest at a variable rate based upon, at the Company’s option, either the Eurodollar rate or the base rate, plus in each case, an applicable margin. The applicable margin for Eurodollar rate loans for the revolving loans and the term A loans ranges, based on the applicable leverage ratio, from 2.75 percent to 3.25 percent per annum and the applicable margin for base rate loans ranges, based on the applicable leverage ratio, from 1.75 percent to 2.25 percent per annum. The applicable margin for Eurodollar rate loans for the term B loans is 3.75 percent per annum and the applicable margin for base rate loans is 2.75 percent per annum. The Company is required to pay a commitment fee equal to 0.50 percent per annum on the undrawn portion available under the revolving loan facility if its leverage ratio is greater than or equal to 3.00 to 1.00, a commitment fee equal to 0.40 percent per annum if its leverage ratio is less than 3.00 to 1.00 but greater than or equal to 2.00 to 1.00 and a commitment fee equal to 0.30 percent per annum if its leverage ratio is less than 2.00 to 1.00. Additionally, the Company is required to pay variable per annum fees equal to the applicable margin for Eurodollar rate loans in respect of outstanding letters of credit. At December 31, 2012, borrowings on the term A loan bore interest at 3.2 percent, and borrowings on the term B loan bore interest at 5.0 percent. The weighted average interest rate at December 31, 2012 was 4.6 percent. The Company is required to make quarterly amortization payments on the term loan A facility in the amount of $2.5 million. The Company is also required to make mandatory prepayments of loans under the new credit agreement, subject to specified exceptions, from excess cash flows and with the proceeds of asset sales, debt issuances and specified other events. The Company’s obligations under the new credit agreement are guaranteed by substantially all of its direct and indirect domestic subsidiaries. The obligations under the new credit agreement and the guarantees are secured by a lien on substantially all of the Company’s tangible and intangible property and by a pledge of all of the equity interests in its direct and indirect domestic subsidiaries. The new credit agreement also places limits on the Company’s and its subsidiaries’ ability to incur liens, incur additional indebtedness, make loans and investments, engage in mergers and acquisitions, engage in asset sales, declare dividends or redeem or repurchase capital stock, alter the business conducted by the Company and its subsidiaries, transact with affiliates, prepay, redeem or purchase subordinated debt and amend or otherwise alter debt agreements. The Company's leverage ratio (consolidated funded debt to trailing 12 months earnings before interest, taxes, depreciation and amortization (EBITDA)) is currently limited to no more than 4.25 to 1.00 and reduces over time to 3.00 to 1.00. As of December 31, 2012, the leverage ratio was approximately 2.73 to 1.00. A failure to comply with these 43 covenants could permit the lenders under the new credit agreement to declare all amounts borrowed under the new credit agreement, together with accrued interest and fees, to be immediately due and payable. As of December 31, 2012 and 2011, the Company was in compliance with all of its debt covenants. As of December 31, 2012, the Company had $72.2 million of borrowing available under our credit facility. 6. Goodwill and Other Identifiable Intangible Assets. The changes in the carrying amount of goodwill for the years ended December 31, 2012 and 2011 are as follows (in thousands): Apex Oxford Life Sciences Healthcare Physician Total Balance as of December 31, 2010 Gross goodwill Accumulated impairment $ Valesta acquisition (see Note 4) HCP acquisition (see Note 4) Translation adjustment Balance as of December 31, 2011 Gross goodwill Accumulated impairment Apex acquisition (see Note 4) Acquisition accounting Translation adjustment Balance as of December 31, 2012 Gross goodwill Accumulated impairment — $ — — — — — — — — 266,788 — — 266,788 — $ 149,483 — 149,483 — — — 149,483 — 149,483 — — — 149,483 — 12,561 — 12,561 16,097 — (990) 27,668 — 27,668 — 1,814 529 30,011 — $ 122,230 (121,717 ) $ 513 — — — 122,230 (121,717) 513 — — — 122,230 (121,717) $ 37,163 — 37,163 — 14,407 — 51,570 — 51,570 — (9) — 51,561 — 321,437 (121,717) 199,720 16,097 14,407 (990) 350,951 (121,717) 229,234 266,788 1,805 529 620,073 (121,717) $ 266,788 $ 149,483 $ 30,011 $ 513 $ 51,561 $ 498,356 Subsequent to the issuance of the Company's annual report on Form 10-K for the year ended December 31, 2011, the Company identified an error of $1.8 million to record deferred tax liabilities and a corresponding increase in goodwill related to Valesta's intangible assets. The Company considers this an immaterial adjustment and has corrected the goodwill and deferred tax liabilities as of December 31, 2012 reflecting the adjustment in the accompanying consolidated balance sheets, the adjustments in the non-cash supplemental disclosures in the consolidated statements of cash flows and related footnote disclosures. This adjustment has no effect on the Company's consolidated statements of operations and comprehensive income (loss). As of December 31, 2012 and December 31, 2011, the Company had the following acquired intangible assets (in thousands): 2012 2011 Estimated Useful Life Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount Subject to amortization: Customer relations Contractor relations 3 months – 10 years 2 - 7 years Non-compete agreements 2 - 7 years Not subject to amortization: Trademarks Goodwill Total 37,871 2,986 144,142 171,852 498,356 $ 103,285 $ 23,338 $ 79,947 $ 11,077 $ 7,891 $ 27,754 1,062 52,154 10,117 1,924 91,988 27,276 899 39,252 25,599 604 34,094 3,186 1,677 295 5,158 — — 171,852 498,356 25,048 229,234 — — 25,048 229,234 $ 814,350 $ 52,154 $ 762,196 $ 293,534 $ 34,094 $ 259,440 44 Amortization expense for intangible assets with finite lives was $18.0 million in 2012, $2.3 million in 2011 and $2.1 million in 2010.

Goodwill and intangible assets with indefinite lives are reviewed for impairment on an annual basis as of October 31 and whenever certain events or changes in circumstances occur. No impairment charge was recorded for any of the reporting units as of October 31, 2012. Based upon the annual goodwill impairment test in 2011, there was no goodwill impairment charge. The Company recognized a goodwill impairment charge of $15.4 million in the fourth quarter of 2010. Goodwill for the Company's impaired reporting unit, Nurse Travel, with a carrying amount of $15.4 million was written down to the implied fair value of $0 resulting in an impairment charge of $15.4 million. 7. 401(k) Retirement Savings Plan, Deferred Compensation Plan and Change in Control Severance Plan. Under the Company’s 401(k) Retirement Savings Plan, which covers eligible employees of On Assignment and its wholly-owned subsidiaries, Assignment Ready Inc., On Assignment Staffing Services, Inc., VISTA, and Oxford, eligible employees may elect to have a portion of their salary deferred and contributed to the plans. The amount of salary deferred, up to certain limits set by the IRS, is not subject to federal and state income tax at the time of deferral, but together with any earnings on deferred amounts, is subject to taxation upon distribution. The plan covers all eligible employees and permits matching or other discretionary contributions at the Company’s discretion. Eligible employees may enroll once they complete three months of service prior to the next quarterly offering. Apex sponsors a 401(k) plan for the benefit of all eligible Apex employees. Employees are eligible to participate after 12 months of service, 1000 hours of work, and attaining the age of 18. Under the terms of the plan, employees are entitled to contribute a portion of their total compensation, within limitations established by the Internal Revenue Code. The Company pledged to make contributions to the 401(k) plans of $3.7 million in 2012 and made contributions of $1.1 million and $0.4 million in 2011 and 2010, respectively. Effective January 1, 1998, the Company implemented the On Assignment, Inc. Deferred Compensation Plan. On September 4, 2008, effective as of January 1, 2008, the Company amended the On Assignment Deferred Compensation Plan and adopted a new plan, called the On Assignment Deferred Compensation Plan – Effective January 1, 2008, applicable to deferrals made on or after January 1, 2005 (referred to herein as the 2008 Deferred Compensation Plan). On April 20, 2011, the Company’s Board of Directors authorized and directed the termination of the 1998 Deferred Compensation Plan and the 2008 Deferred Compensation Plan (collectively referred to as the Plans), effective May 2, 2011. The deferred compensation liability under the deferred compensation plans was approximately $1.9 million at December 31, 2011. Life insurance policies were maintained as a funding source to the plans, under which the Company is the sole owner and beneficiary of such insurance. At December 31, 2011, the cash surrender value of these life insurance policies was $2.1 million, reflected in other current assets in the accompanying Consolidated Balance Sheets. As a result of the termination, the Company received $1.5 million related to the cash surrender value of the life insurance proceeds, which were maintained as a funding source to the deferred compensation plans, and in June 2012, distributed $1.2 million to plan participants according to the terms of the Plans. As a result of the merger with Apex, the Company assumed a long-term incentive program, which began in 2010, that provides for a total award of up to $10.0 million to eligible employees, based on the attainment by Apex of stipulated revenues and EBITDA goals during a three year performance period. The Company determined that it was probable that the revenue and EBITDA goals for Apex would be reached in 2012 and the Company accrued approximately $7.9 million at May 15, 2012 (the effective date of the acquisition), and $10.0 million at December 31, 2012, which are included in deferred compensation in the Consolidated Balance Sheet. The Company adopted the On Assignment, Inc. Change in Control Severance Plan (the CIC Plan) to provide severance benefits for officers and certain other employees who are terminated following an acquisition of the Company. This CIC Plan was adopted as of February 12, 2004 and amended and restated on December 11, 2008. Under the CIC Plan, eligible employees with titles of vice president or higher who are involuntarily terminated within eighteen months after a change in control, as defined in the CIC Plan will be entitled to (i) a payment equal to the employee's annual salary plus the employee's target bonus, payable in a lump sum, and (ii) a lump sum payment representing the cost of continuation of health and welfare benefits, under the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA). Severance pay under the CIC Plan varies depending on the eligible employee's length of service and position with the Company. The Company entered into an Amended and Restated Executive Change of Control Agreement with the Chief Executive Officer on December 11, 2008, primarily for the purpose of causing his previous agreement to meet the requirements of Code Section 409A. This agreement supersedes the CIC Plan and provides, in the event of an involuntary termination occurring within six months and ten days following a change of control of the Company, that the Chief Executive Officer is entitled to the benefits including salary and bonus payments, continuation of 45 health and welfare benefits and car allowance, cash payments equal to insurance premiums and retirement and deferred compensation contributions, and payment for outplacement services. Additionally, under the arrangements, immediately prior to a change of control, all outstanding Company stock options, restricted stock and stock units held by the Chief Executive Officer will become fully vested (and, in the case of options, remain exercisable for an extended period), subject to any express limitations contained in the Chief Executive Officer's employment agreement. In addition, the agreement entitles the Chief Executive Officer to tax gross-up payments in the event that any payments are subject to “golden parachute” excise taxes under IRS Code Section 280G. The Company entered into an Executive Change of Control Agreement with the Chief Financial Officer on September 1, 2012. This agreement supersedes the CIC Plan and provides, in the event of an involuntary termination occurring within six months and ten days following a change of control of the Company, for benefits including salary and bonus payments, car allowance, healthcare coverage, cash payment equal to premiums for life insurance and disability insurance, and payment for outplacement services. Immediately prior to a change of control, all outstanding Company stock options, restricted stock and stock units held by the officer will become fully vested (and, in the case of options, remain exercisable for an extended period). The agreement provides that the Chief Financial Officer with a best pay cap reduction for any excess parachute payments under Code Section 280G unless he would receive a greater after-tax benefit without the reduction and after paying the related excise tax. 8. Commitments and Contingencies. The Company leases its facilities and certain office equipment under operating leases, which expire at various dates through 2022. Certain leases contain rent escalations and/or renewal options. Rent expense for all significant leases is recognized on a straight-line basis. The balance of the deferred rent liability reflected in other current liabilities in the accompanying Consolidated Balance Sheets was $0.3 million at December 31, 2012 and 2011 and the balance reflected in other long-term liabilities was $3.8 million and $2.1 million, at December 31, 2012 and 2011 respectively. The following is a summary of specified contractual cash obligation payments by the Company as of December 31, 2012 (in thousands): 2013 2014 2015 2016 2017 Thereafter Total Long-Term Debt Operating Leases Related Party Leases Total $ 10,000 $ 13,545 $ 1,266 $ 10,000 10,000 10,000 52,500 334,088 11,117 9,210 6,386 3,588 6,764 1,299 1,168 694 175 — $ 426,588 $ 50,610 $ 4,602 $ 24,811 22,416 20,378 17,080 56,263 340,852 481,800 Rent expense, which is included in SG&A expenses, was $14.1 million for 2012, $8.6 million for 2011, and $8.4 million for 2010. As discussed in Note 1, the Company carries large retention policies for its workers’ compensation liability and its medical malpractice exposures. The workers' compensation and medical malpractice loss reserves are based upon an actuarial report obtained from a third party and determined based on claims filed and claims incurred but not reported. The Company accounts for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates, differences in estimates and actual payments for claims are recognized in the period that the estimates changed or the payments were made. The workers' compensation and medical malpractice loss reserves were approximately $10.3 million and $10.4 million at December 31, 2012 and 2011, respectively. Additionally, the Company has unused stand-by letters of credit outstanding to secure obligations for workers’ compensation claims with various insurance carriers. The unused stand-by letters of credit at December 31, 2012 and December 31, 2011 were $2.8 million and $2.4 million, respectively. The Company is subject to earn-out obligations entered into in connection with certain of its acquisitions. If the acquired businesses meet predetermined financial targets, the Company is obligated to make additional cash payments in accordance with the terms of such earn- out obligations. As of December 31, 2012, the Company has potential future earn-out obligations of approximately $9.1 million through 2013. The Company has entered into various non-cancelable operating leases, primarily related to its facilities and certain office equipment used in the ordinary course of business. As a result of the Apex acquisition, the Company leases two properties owned by related parties. At December 31, 2012 and 2011, the Company has an income tax reserve in other long-term liabilities related to uncertain tax positions of $0.4 million and $0.3 million, respectively. 46 Legal Proceedings The Company is involved in various legal proceedings, claims and litigation arising in the ordinary course of business. However, based on the facts currently available, the Company does not believe that the disposition of matters that are pending or asserted will have a material effect on its consolidated financial statements. 9. Income Taxes. The provision (benefit) for income taxes consists of the following (in thousands): Current: Federal State Foreign Deferred: Federal State Foreign Change in valuation allowance Year Ended December 31, 2012 2011 2010 $ 20,849 $ 9,814 $ 1,748 3,353 2,645 26,847 5,467 565 (822) 5,210 246 1,447 1,465 12,726 3,759 488 (261) 3,986 454 $ 32,303 $ 17,166 $ 522 412 2,682 2,271 — (212) 2,059 215 4,956 Income (loss) before income taxes consists of the following (in thousands): United States Foreign Year Ended December 31, 2012 2011 2010 $ $ 72,184 2,772 74,956 $ $ 37,405 4,058 41,463 $ $ (6,071) 1,130 (4,941) 47 The components of deferred tax assets (liabilities) are as follows (in thousands): Deferred income tax assets (liabilities): Current: Allowance for doubtful accounts Employee related accruals State taxes Workers’ compensation and medical malpractice loss reserves Prepaid insurance Other Non-current: Intangibles Depreciation expense Stock-based compensation Net operating loss carryforwards Other Valuation allowance Total net deferred income tax liability December 31, 2012 December 31, 2011 $ 1,150 $ 3,419 1,064 4,683 (631) 462 10,147 (23,662) (4,449) 2,852 1,191 1,975 (22,093) (916) $ (12,862) $ 1,007 2,923 534 4,277 (319) 849 9,271 (15,559) (3,867) 3,428 1,054 758 (14,186) (670) (5,585) The reconciliation between the amount computed by applying the U.S. federal statutory tax rate of 35.0 percent for 2012, 35.0 percent for 2011, and 34.0 percent for 2010 to income before income taxes and the income tax provision is as follows (in thousands): Income tax provision at the statutory rate State income taxes, net of federal benefit Impairment of goodwill Permanent difference – disallowed meals and entertainment expenses Permanent difference – settlement of earn-out Valuation allowance related to foreign jurisdictions Income tax contingency Foreign tax rate differential Other Year Ended December 31, 2012 2011 2010 $ 26,235 $ 14,512 $ (1,680) 2,952 — 1,822 — 246 276 14 758 1,527 — 1,093 (445) 454 (91) (222) 338 460 5,236 614 — 215 (16) (181) 308 $ 32,303 $ 17,166 $ 4,956 As of December 31, 2012, the Company had no federal net operating losses, state net operating losses of approximately $9.5 million and foreign net operating losses of approximately $3.1 million. The state net operating losses can be carried forward up to 20 years and begin expiring in 2013. The foreign net operating losses in the United Kingdom can be carried forward indefinitely and the net operating losses in Spain can be carried forward up to 18 years beginning from the first period of profits. The Company has recorded a valuation allowance of approximately $0.9 million and $0.7 million at December 31, 2012 and December 31, 2011, respectively, related to net operating loss carryforwards. At December 31, 2012, the Company had accumulated net foreign earnings of $13.0 million. The Company did not provide deferred taxes on the excess of the financial reporting over the tax basis in its investment in foreign subsidiaries since the Company intends to permanently reinvest the undistributed earnings of its foreign subsidiaries. The determination of additional deferred taxes that have not been provided is not practicable. The Company had gross deferred tax assets of $17.7 million and $14.4 million and gross deferred tax liabilities of $30.5 million and $19.9 million at December 31, 2012 and 2011, respectively. 48 The Company receives a tax deduction for stock-based awards upon exercise of a non-qualified stock options or as the result of disqualifying dispositions made by directors, officers and employees. A disqualifying disposition occurs when stock acquired through the exercise of incentive stock options or the Employee Stock Purchase Plan is disposed of prior to the required holding period. The Company also receives a tax deduction upon the vesting of restricted stock units or restricted stock awards. The Company received tax deductions of $22.8 million and $7.5 million, respectively, from stock-based awards in 2012 and 2011. As of December 31, 2012, the Company had $0.4 million of gross unrecognized tax benefits, which includes penalties and interest, all of which was carried in other long-term liabilities. If the Company’s positions are sustained by the taxing authority in favor of the Company, the entire $0.4 million would reduce the Company’s effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The amount of interest and penalties recognized in the financial statements is not significant. The following is a reconciliation of the total amounts of unrecognized tax benefits (in thousands): Unrecognized Tax Benefit beginning of year Gross decreases - tax positions in prior year Reductions for tax positions as a result of a lapse of the applicable statute of limitations Gross increases - tax positions in prior year Unrecognized Tax Benefit end of year Year Ended December 31, 2012 2011 2010 251 $ 358 $ (34) — 159 376 — (107) — $ 251 $ 397 (39) — — 358 $ $ The Company believes that there will be no significant increases or decreases to unrecognized tax benefits within the next twelve months. The Company is subject to taxation in the United States and various states and foreign jurisdictions. The IRS has examined and concluded all tax matters for years through 2009. 10. Earnings per Share. Basic earnings per share are computed based upon the weighted average number of shares outstanding and diluted earnings per share are computed based upon the weighted average number of shares and dilutive share equivalents (consisting of incentive stock options, non- qualified stock options, restricted stock units, restricted stock awards and employee stock purchase plan contributions) outstanding during the periods using the treasury stock method. The following is a reconciliation of the shares used to compute basic and diluted earnings per share (in thousands): Weighted average number of common shares Dilutive effect of stock-based awards Number of shares used to compute diluted earnings per share Year Ended December 31, 2012 2011 2010 46,739 1,087 47,826 36,876 882 37,758 36,429 — 36,429 The following table presents the weighted average share equivalents outstanding during each period that were excluded from the computation of diluted earnings per share because the exercise price for these options was greater than the average market price of the Company’s shares of common stock during the respective periods. Also excluded from the computation of diluted earnings per share were other share equivalents that became anti-dilutive when applying the treasury stock method. Anti-dilutive common share equivalents outstanding 11. Stock-based Compensation: Incentive Award Plan and Employee Stock Purchase Plan. Year Ended December 31, 2012 2011 2010 83 1,039 1,339 The Company believes that stock-based compensation better aligns the interests of its employees and directors with those of its shareholders versus exclusively providing cash-based compensation. Stock-based compensation provides incentives to retain and motivate executive officers and key employees responsible for driving Company performance and maintaining important relationships that contribute to the growth of the Company. 49 Compensation expense charged to operations related to stock-based compensation was $9.7 million, $6.9 million, and $7.7 million for each of the years ended December 31, 2012, 2011 and 2010, respectively, and is included in the Consolidated Statements of Operations and Comprehensive Income (Loss) in SG&A expenses. The Company has recognized an income tax benefit of $3.5 million, $2.5 million, and $2.9 million for the years ended December 31, 2012, 2011 and 2010, respectively in the consolidated statements of operations for stock-based compensation arrangements. Effective June 3, 2010, shareholders of the Company approved the adoption of the On Assignment, Inc. 2010 Incentive Award Plan (the 2010 Plan), which replaced the Company’s Restated 1987 Stock Option Plan (the 1987 Plan). The 2010 Plan permits the grant of stock options, including incentive stock options, nonqualified stock options, restricted stock awards (RSAs), dividend equivalent rights, stock payments, deferred stock, restricted stock units (RSUs), performance shares and other incentive awards, stock appreciation rights and cash awards to its employees, directors and consultants for up to 2,184,983 shares of common stock, which included 884,983 shares that remained available for issuance under the 1987 Plan as of June 3, 2010. The 2010 Plan allows for stock option awards to be granted with an exercise price equal to the closing market price of the Company’s stock at the date of grant. Stock option awards generally vest over four years of continuous service with the Company and generally have ten-year contractual terms. RSUs and RSAs generally vest over a three year continuous service period, though individual award vesting terms vary within these parameters. Certain stock option awards and RSUs and RSAs provide for accelerated vesting in the event of a change in control (see Note 7). Options or awards that are canceled or forfeited are added back to the pool of shares available for issuance under the 2010 Plan. As of December 31, 2012, there were 1,502,481 shares available for issuance under the 2010 Plan. The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model that incorporates assumptions disclosed in the table below. Expected volatility is based on historical volatility of the underlying stock for a period consistent with the expected lives of the stock options as the Company believes this is a reasonable representation of future volatility. Additionally, the Company analyzes historical stock option exercise behavior and vesting patterns for RSUs and RSAs in order to estimate employee turnover rates (i.e. forfeiture rates). The forfeiture rate, set by management, is used to estimate the number of options and awards that will eventually vest and the associated impact on stock-based compensation expense. The expected life, or term, of options granted is derived from historical exercise behavior and represents the period of time that stock option awards are expected to be outstanding. The Company has selected a risk- free rate based on the implied yield available on U.S. Treasury Securities with a maturity equivalent to the options’ expected term. For RSUs and RSAs, the Company records compensation expense based on the fair market value of the awards on the grant date. The preceding paragraphs describe the general terms of most stock-based incentive awards granted by the Company. However, the Company has granted a discrete set of stock-based awards to its Chief Executive Officer (CEO) and other corporate officers that differ from those generally stated terms. The grant-date fair-value of these awards, which was determined by applying certain provisions of the stock compensation guidance relative to performance-based and market-based awards, is generally being expensed over the vesting term. The impact of these awards is reflected in the detailed RSU and RSA disclosures below. All awards are subject to the officer’s continued employment through such vesting dates, however, the vesting of certain awards will accelerate upon the occurrence of a change in control of the Company and/or upon certain qualifying terminations of employment. 2012 Employment Inducement Incentive Award Plan Effective May 15, 2012 (amended and restated as of December 13, 2012), the Board of Directors adopted the 2012 Employment Inducement Incentive Award Plan (2012 Inducement Award Plan). The 2012 Inducement Award Plan includes terms similar to the 2010 Plan and allows for grants of stock to employees as employment inducement awards pursuant to NYSE rules. CEO Awards The Company granted discrete stock-based awards to its CEO as follows: (i) a market based award in 2010 with a grant date fair market value of $0.5 million. The award was expensed over a service period of 2.6 years and the number of shares were determined by dividing $0.5 million by the closing price of the Company stock on February 1, 2013, contingent upon the achievement of defined market targets, which were met, (ii) a performance based award on March 8, 2011, which had a grant date fair market value of $1.0 million and was expensed over a service period of 9.9 months, the financial performance objectives were met by the Company during the twelve month period ending December 31, 2011 and 24,654 shares vested on December 31, 2012 and the remaining number of shares will be determined by dividing $0.5 million by the closing price of the Company’s stock on February 1, 2014, and (iii) a performance based award on March 23, 2012, which had a grant date fair market value of $1.5 million and was expensed over a service period of 9.3 months, the financial performance objectives were met by the Company during the twelve month period ending December 31, 2012 and 24,654 shares vested on December 31, 2012 and the remaining number of shares will be determined by dividing $0.5 million by the closing price of the Company’s stock on each of February 1, 2014 and February 1, 2015. The Company classifies these awards as liability awards until the number of shares is determined. The liability of $2.0 million related to these awards is included in other accrued expenses and other long-term liabilities in the accompanying Consolidated Balance Sheets as of December 31, 2012. On December 31, 2012, the CEO was awarded 39,448 RSUs with a grant date fair market value of $0.8 million, contingent upon the Company meeting certain financial performance objectives based on adjusted EBITDA approved by the Compensation Committee over the twelve-month period ending December 31, 2013 and continued employment through January 1, 2014. 50 On March 5, 2012, the CEO was awarded 45,372 RSUs with a grant date fair market value of $0.6 million, of which 22,686 shares vested on December 31, 2012 and the remaining 22,686 shares will vest on January 4, 2014. As of December 31, 2012, the performance targets had been fully achieved and certified by the Compensation Committee of the Board of Directors. On March 8, 2011, the CEO was awarded 58,754 RSUs with a grant date fair market value of $0.6 million, which vested in two equal components of $0.3 million on January 1, 2012 and December 31, 2012. As of December 31, 2011, the performance targets had been fully achieved and certified by the Compensation Committee. On March 17, 2010, the CEO was granted 67,568 RSUs, with a grant-date fair value of $0.5 million, of which 33,784 RSUs vested on February 1, 2011 and 33,784 RSUs vested on February 1, 2012. As of December 31, 2011, the performance targets had been fully achieved and certified by the Compensation Committee and the grant-date fair value was expensed over the respective vesting periods for each of the two components. On November 4, 2009, the Company entered into an employment agreement with the CEO that provided for three annual stock award grants with grant-date values of $0.8 million each, based on performance objectives for 2010 through 2012 that vested on February 1, 2011, January 1, 2012, and December 31, 2012, respectively, contingent upon achieving positive adjusted EBITDA, which were met for each of the respective periods. The grant-date fair value of the RSUs are expensed over the vesting term, based on an estimate of the percentage achievement of the applicable performance targets. All awards were subject to the CEO’s continued employment through applicable vesting dates. All awards may vest on an accelerated basis in part or in full upon the occurrence of certain events. Other Executive Officer Awards The Company records stock-based compensation expense over the vesting period of the awards based on the probability that the performance objectives will be met and that the executives will maintain their employment through the respective vesting dates. In the first quarter of 2012, the Company granted RSUs to certain executive officers with an aggregate grant-date fair value of $1.7 million. Of the $1.7 million, $0.9 million will vest in three equal annual increments subject to continued employment on each succeeding grant-date anniversary. The remaining $0.8 million vested on December 31, 2012, as certain performance objectives approved by the Compensation Committee were attained and certified by the Compensation Committee. On May 15, 2012, the Company granted RSUs to certain executive officers in conjunction with the acquisition of Apex. The aggregate grant-date fair value of these grants was $0.8 million. Of the $0.8 million, $0.6 million will vest in three equal annual increments subject to continued employment on each succeeding grant-date anniversary. The remaining $0.2 million will vest on May 31, 2013, subject to continued employment, Apex attaining certain performance objectives and certification by the Compensation Committee. In the first quarter of 2011, the Company granted RSUs to certain executive officers with an aggregate grant-date fair value of $1.6 million Of the $1.6 million, $0.9 million will vest in three annual increments subject to continued employment on each succeeding grant-date anniversary. The remaining $0.7 million vested on January 3, 2012, as certain performance objectives approved by the Compensation Committee were attained and certified by the Compensation Committee. In the first quarter of 2010, the Company granted RSUs to certain executive officers with an aggregate grant-date fair value of $1.2 million. Sixty percent of the total RSU awards will vest in three annual increments subject to continued employment on each succeeding grant-date anniversary. Forty percent of the awards will vest in three consecutive annual installments contingent upon the officer attaining certain performance objectives certified by the Compensation Committee. Accordingly, the Company records stock-based compensation expense over the vesting period of these awards based on the probability that the performance objectives will be met and that the executives will maintain their employment through the respective vesting dates.

There were no non-employee director stock options outstanding as of December 31, 2012. The weighted-average grant-date fair value of options granted during the years ended December 31, 2012, 2011 and 2010 was $10.34, $5.04, and $3.80 per option, respectively. The total intrinsic value of options exercised during the years ended December 31, 2012, 2011 and 2010 was $9.7 million, $1.3 million, and $0.2 million. As of December 31, 2012 there was unrecognized compensation expense of $1.5 million related to unvested stock options based on options that are expected to vest. The unrecognized compensation expense is expected to be recognized over a weighted-average period of 2.65 years. Restricted Stock Units and Restricted Stock Awards A summary of the status of the Company’s unvested RSUs and RSAs as of December 31, 2012 and changes during the year then ended are presented below: Unvested RSUs and RSAs outstanding at January 1, 2012 Granted Market value share count adjustment for liability awards Vested Forfeited Unvested RSUs and RSAs outstanding at December 31, 2012 Unvested and expected to vest RSUs and RSAs outstanding at December 31, 2012 52 Weighted Average Grant-Date Fair Value Per Unit / Award Restricted Stock Units / Awards 1,208,166 $ 1,168,172 (84,858) (865,833) (34,813) 1,390,834 1,149,735 $ $ 8.99 16.94 20.28 10.04 9.67 14.31 14.50 The number of shares vested in the table above includes 345,181 shares surrendered by the employees to the Company for payment of minimum tax withholding obligations. Shares of stock withheld for purposes of satisfying minimum tax withholding obligations are again available for issuance under the Plan. The table above includes 760,788 RSUs with an aggregate grant-date fair value of $12.3 million granted on May 15, 2012 to certain Apex employees. The grants generally vest 25 percent on the first anniversary of the grant date and in 12 quarterly installments thereafter, subject to continued employment. Additionally, the table above includes 42,392 RSUs that were awarded to non-employee directors on September 1, 2012, of which 21,196 shares vested immediately upon issuance and the remaining shares will vest on September 1, 2013. The weighted average grant-date fair value of these awards was $16.51. There was unrecognized compensation expense of $210,000 as of December 31, 2012 related to these RSUs that will be recorded over the remaining term of eight months. In December 2012, the Company converted certain RSUs for six executive officers to RSAs and accelerated the vesting of those awards. The original vesting dates for these awards were in January 2013. The awards were accelerated in order to provide an opportunity to accelerate the application of taxes applicable to all or a portion of the equity awards and thereby provide each executive with the certainty of known 2012 tax consequences. There was no incremental compensation cost as a result of this acceleration. The weighted-average grant-date fair value of RSUs and RSAs granted during the years ended December 31, 2012, 2011 and 2010 was $16.01, $9.18 and $7.26 per award, respectively. The total intrinsic value of RSUs and RSAs vested during the years ended December 31, 2012, 2011 and 2010 was $13.7 million, $6.4 million and $3.7 million, respectively. As of December 31, 2012, there was unrecognized compensation expense of $12.8 million related to unvested RSUs and RSAs based on awards that are expected to vest. The unrecognized compensation expense is expected to be recognized over a weighted-average period of 2.6 years. Employee Stock Purchase Plan Effective June 3, 2010, the date of shareholder approval of the On Assignment 2010 Employee Stock Purchase Plan (the ESPP), the Company reinstated the employee stock purchase program for issuance of up to 3,500,000 shares of common stock with the first offering periods. The ESPP allows eligible employees to purchase common stock of the Company, through payroll deductions, at 85 percent of the lower of the market price on the first day or the last day of semi-annual purchase periods. The ESPP is intended to qualify as an “employee stock purchase plan” under IRS Code Section 423. Eligible employees may contribute up to a certain percentage set by the plan administrator of their eligible earnings toward the purchase of the stock (subject to certain IRS limitations). In accordance with the ESPP, shares of common stock are transferred to participating employees at the conclusion of each six month enrollment period, which now end on the last business day of the month in March and September each year. The Company issued 154,934 and 187,036 shares of common stock in 2012 and 2011, respectively, under the ESPP. In 2010, no shares were issued under the ESPP. Compensation expense of shares purchased under the ESPP is measured based on a Black-Scholes option-pricing model. The model accounts for the discount from market value and applies an expected life in line with each six month purchase period. The weighted average fair value of stock purchased under the ESPP was $3.53 and $2.10 for the years ended December 31, 2012 and 2011, respectively. The stock- based compensation expense related to the ESPP was $0.8 million in 2012, $0.4 million in 2011 and $0.1 million in 2010. 12. Business Segments. The Company has five reportable segments: Apex, Oxford (formerly IT and Engineering), Life Sciences, Healthcare and Physician. The Apex segment provides mission-critical IT operations professionals for contract, contract-to-hire and permanent placement positions to Fortune 1000 and mid-market clients across the United States, and offers consulting services for other select project-based needs. Apex provides staffing and services support for companies from all major industries, including financial services, business services, consumer and industrials, technology, healthcare, government services, and communications. The Oxford segment provides high-end contract and direct placement services of information technology and engineering professionals with expertise in specialized information technology; software and hardware engineering; and mechanical, electrical, validation and telecommunications engineering fields. The Life Sciences segment provides contract, contract-to-permanent and direct placement services of laboratory and scientific professionals to the biotechnology, pharmaceutical, food and beverage, medical device, personal care, chemical and environmental industries. These contract staffing specialties include chemists, clinical research associates, clinical lab assistants, engineers, biologists, biochemists, microbiologists, molecular biologists, food scientists, regulatory affairs specialists, lab assistants and other skilled scientific professionals. The Healthcare segment includes the combined results of the Nurse Travel and Allied Healthcare lines of business. The lines of business have been aggregated into the Healthcare segment based on similar economic characteristics, end-market customers and 53 management personnel. The Healthcare segment provides contract, contract-to-permanent and direct placement of professionals from a number of healthcare, medical financial and allied occupations. These contract staffing specialties include nurses, specialty nurses, respiratory therapists, surgical technicians, imaging technicians, x-ray technicians, medical technologists, phlebotomists, coders, billers, claims processors and collections staff. The Physician segment provides contract and direct placement physicians to healthcare organizations. The Physician segment works with nearly all medical specialties, placing locum tenens physicians in hospitals, community-based practices, and federal, state and local facilities. The Company’s management evaluates the performance of each segment primarily based on revenues, gross profit and operating income. The information in the following table is derived directly from the segments’ internal financial reporting used for corporate management purposes.

Derivative Instruments. December 31, 2012 2011 2010 $ $ 40,062 2,006 42,068 $ $ 19,078 1,033 20,111 $ $ 19,826 754 20,580 The Company utilizes derivative financial instruments to manage interest rate risk. The Company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company’s derivative instruments are recorded at their fair value, and are included in other long-term assets, other long-term liabilities and other liabilities in the Consolidated Balance Sheets. Effective August 8, 2012, the Company entered into three interest rate cap agreements to hedge a portion of its interest rate exposure on its senior secured debt (collectively referred to as the Interest Rate Caps). Under the terms of the Interest Rate Caps, the one month LIBOR rate will not exceed 3.0 percent. From a practical standpoint, the interest rate in the hedged portion of the debt is limited to a maximum of 3.0 percent plus the Eurodollar applicable margin. The total initial notional amount was $223.1 million and is scheduled to decline over the term of the Interest Rate Caps. Each of the Interest Rate Caps terminates on August 10, 2015. On February 18, 2011, the Company entered into an interest rate swap agreement to hedge a portion of its interest rate exposure on its senior secured debt (the Interest Rate Swap). The Interest Rate Swap has a notional amount of $25.0 million and fixes a portion of the Company’s base borrowing rate, which is a floating rate based on a LIBOR swap rate that resets periodically. The Interest Rate Caps and the Interest Rate Swap were designated as hedging instruments for accounting purposes and are accounted for as a cash flow hedges. The effective portion of unrealized losses on cash flow hedges are included in accumulated other comprehensive income until the periodic interest settlements occur, at which time they will be recorded as interest expense in the Consolidated Statements of Operations and Comprehensive Income. The Company expects to reclassify losses of $0.4 million (pretax) from accumulated other comprehensive income to interest expense in the Consolidated Statements of Operation within the next twelve months. 55 As a result of the use of derivative instruments, the Company is exposed to risk that the counterparties will fail to meet their contractual obligations. To mitigate the counterparty credit risk, the Company only enters into contracts with carefully selected major financial institutions based upon their credit ratings and other factors, and continually assess the creditworthiness of counterparties. As of December 31, 2012, the counterparty to the interest rate contracts had investment grade ratings and has performed in accordance with their contractual obligations. The fair values of derivative instruments in the Consolidated Balance Sheets as of December 31, 2012 and 2011 are as follows (in thousands): Derivative designated as hedging instrument under ASC 815 Balance Sheet Classification 2012 2011 Interest rate contracts Interest rate contracts Interest rate contracts Other long-term assets Other liabilities Other long-term liabilities $ $ 69 $ (362) (55) (348) $ — (310) (298) (608) The following tables reflect the effect of derivative instruments on the Consolidated Statements of Operations and Comprehensive Income (Loss) for the years ended December 31, 2012, 2011 and 2010 (in thousands): Derivatives in Cash Flow Hedging Relationships Amount of Gain/Loss Recognized in Accumulated Other Comprehensive Income on Derivative 2012 2011 2010 Interest rate contracts $ (21) $ (380) $ — Location of Gain/Loss Reclassified from Accumulated Other Comprehensive Income into Income Amount of Gain/Loss Reclassified from Accumulated Other Comprehensive Income into Income Interest rate contracts Interest expense 14. Fair Value Measurements. 2012 2011 2010 $ 369 $ 310 $ — The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. The recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value based on their short-term nature. Long-term debt recorded in the Company’s Consolidated Balance Sheets at December 31, 2012 was $426.6 million. The fair value of the long-term debt was determined using the quoted price technique, based on Level 2 inputs including the yields of comparable companies with similar credit characteristics, was $430.0 million. The interest rate swap and interest rate caps are measured using the income approach. The fair value reflects the estimated amounts that the Company would pay or receive based on the present value of the expected cash flows derived from market rates and prices. As such, these derivative instruments are classified within Level 2. The Company has obligations, to be paid in cash, to the former owners of Valesta and HCP, if certain future financial goals are met. The fair value of this contingent consideration is determined using an expected present value technique. Expected cash flows are determined using the probability - weighted average of possible outcomes that would occur should certain financial metrics be reached. There is no market data available to use in valuing the contingent consideration, therefore, the Company developed its own assumptions related to the future financial performance of the businesses to evaluate the fair value of these liabilities. As such, the contingent consideration is classified within Level 3. In connection with estimating the fair value of the contingent consideration, the Company develops various scenarios (base case, downside case, and upside case) and weights each according to the probability of occurrence. The probabilities range from 10 percent to 80 percent, with the most significant weighting given to the base case at 80 percent. These scenarios are developed based on the expected financial performance of the acquired companies, with revenue growth rates being a primary input to the calculation. These revenue growth 56 rates range from (4.0) percent to 16.1 percent. An increase or decrease in the probability of achievement of any of these scenarios could result in a significant increase or decrease to the estimated fair value. The fair value is reviewed on a quarterly basis based on most recent financial performance of the most recent fiscal quarter. An analysis is performed at the end of each fiscal quarter to compare actual results to forecasted financial performance. If performance has deviated from projected levels, the valuation is updated for the latest information available. The significant assumptions that may materially affect the fair value are developed in conjunction with the guidance of the division presidents, division vice presidents, and chief financial officer to ensure that the most accurate and latest financial projections are used and compared with the most recent financial results in the fair value measurement. The liabilities for the contingent consideration were established at the time of the acquisition and are evaluated at each reporting period. The current liability is included in the Consolidated Balance Sheets in the current portion of accrued earn-outs and the non-current portion is included in accrued earn-outs. Fair value adjustments are included in the Consolidated Statements of Operations and Comprehensive Income in S&GA expenses. The assets and liabilities measured at fair value on a recurring basis are as follows (in thousands): As of December 31, 2012 Fair Value Measurements Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Interest rate contracts Contingent consideration to be paid in cash for the acquisitions $ $ — $ — $ (348 ) $ — $ — $ (7,577 ) $ (348) (7,577) As of December 31, 2011 Fair Value Measurements Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Interest rate contracts Contingent consideration to be paid in cash for the acquisitions $ $ — $ — $ (608 ) $ — $ — $ (9,856 ) $ (608) (9,856) Reconciliations of liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) are as follows (in thousands): Contingent consideration for acquisitions -- Balance at beginning of year Additions for acquisitions Payments on contingent consideration Settlements of contingent consideration Fair value adjustments Foreign currency translation adjustment Year Ended December 31, 2012 2011 $ (9,856 ) $ — 1,198 — 1,215 (134) (3,700 ) (10,346 ) 1,731 1,369 640 450 Balance at end of year $ (7,577 ) $ (9,856 ) Certain assets and liabilities, such as goodwill, are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). For 2012, no fair value adjustments were required for non- financial assets or liabilities. 57 15. Subsequent Event. On February 12, 2013, the Company sold its Nurse Travel Division, included in the Healthcare segment, for $31.0 million in cash. The Nurse Travel Division was not deemed to be a core offering and represented approximately five percent of revenues in 2012. The Company has agreed to provide certain back office services during a transitional period. 16. Unaudited Quarterly Results. The following tables present unaudited quarterly financial information during the years ended December 31, 2012 and 2011. In the opinion of the Company’s management, the quarterly information contains all adjustments, consisting only of normal recurring accruals, necessary for a fair presentation thereof. The operating results for any quarter are not necessarily indicative of the results for any future periods. Subsequent to the issuance of the Company's quarterly report on Form 10-Q for the second quarter of 2012, the Company identified an immaterial classification error of $0.5 million related to certain vendor fees paid by Apex Systems, Inc., which we acquired in May 2012 (see Note 4 - Acquisitions). Such fees should have been recorded as revenues, rather than in costs of services. The Company considers this an immaterial reclassification and has presented the revenues and cost of services for the year ended December 31, 2012 reflecting the reclassification in the pro forma revenues in Note 4 - Acquisitions, and revenues in the table below. The Company will present the corrected results for the three and six months ended June 30, 2012 in future filings. This reclassification has no effect on the Company's consolidated balance sheets or consolidated statement of cash flows.

Calabasas, California We have audited the internal control over financial reporting of On Assignment, Inc. and subsidiaries (the “Company”) as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management's Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Apex Systems, Inc., which was acquired on May 15, 2012 and whose financial statements constitute 47% and 59% of net and total assets, respectively, 41% of revenues, and -17% of net income of the consolidated financial statement amounts as of and for the year ended December 31, 2012. Accordingly, our audit did not include the internal control over financial reporting at Apex Systems, Inc. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2012 of the Company and our report dated March 18, 2013 expressed an unqualified opinion on those financial statements and financial statement schedule and included an explanatory paragraph regarding the acquisition of Apex Systems, Inc. /s/ Deloitte & Touche LLP Los Angeles, California March 18, 2013 59 Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure Not applicable. Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures As of the end of the period covered by this report, the Company’s management carried out an evaluation, under the supervision and with the participation of our Principal Executive Officer and Principal Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934). Based on this evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that our disclosure controls and procedures are effective as of the end of the period covered by this report. The term “disclosure controls and procedures” means controls and other procedures of the Company that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. “Disclosure controls and procedures” include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management’s Report on Internal Control Over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Securities Exchange Act of 1934) for the Company. The term “internal control over financial reporting” is defined as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: • • • Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; Provide reasonable assurance that the transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and Provide reasonable assurance regarding prevention of timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate. Management, under the supervision and with the participation of our Principal Executive Officer and Principal Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2012. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control- Integrated Framework. Based on our assessment and those criteria, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2012. Our independent registered public accounting firm, Deloitte & Touche LLP, has included an attestation report on our internal control over financial reporting, which is included above. For purposes of conducting its 2012 evaluation of the effectiveness of the Company's internal control over financial reporting, management has excluded the acquisition of Apex, completed on May 15, 2012, whose financial statements constitute 47 percent and 59 percent of net and total assets, respectively, 41.0 percent of revenues, and -17.0 percent of net income, of the consolidated financial statement amounts as of and for the year ended December 31, 2012. Refer to Note 4 in Part II, Item 8 of this report for further discussion of the acquisitions and their impact on the Company's Consolidated Financial Statements. Changes in Internal Controls There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s fourth quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
