increased holidays and vacation days taken, duringwhich is usually highest in the fourth quarter of theeach calendar year. In addition, we experience an increase in directyear; and
increased costs of services and a corresponding decrease in gross profit in the first fiscal quarter of each year as a result of certain annual U.S. state and federal employment tax resets that occur at the beginning of each calendar year, which negatively impacts our gross profit and overall profitability in the first fiscal quarter of each calendar year.

The September 20162018 report published by Staffing Industry Analysts (“SIA”) stated that temporary technology staffing is expected to experience growth of 6%3% in 2017.2019. Digital transformation, as a general trend, is driving organizations across all industries to increase their technology investments as competition and the speed of change intensifies. Nontraditional competitors are also entering new end markets; thus, putting increased pressure on companies to invest in innovation and the evolution of their business models. We believe these secular drivers will transcend traditional cyclical patterns as our clients' business models adjust. At the primary drivers of this growthmacro level, demand is also being driven by an ever-changing and complex regulatory and employment law environment, which increases the continuing use of temporary staffing as a solution during uncertain economic cycles are the increasingly strict regulatory environment andoverall cost of employment both of whichfor many companies. These factors, among others, are driving the systemic use ofcontinuing to drive companies to look to temporary staffing particularly in project-based workproviders, such as technology, and the increasing demand for talent in areas like cybersecurity, cloud-based computing, data analytics and application development. The secular drivers of technology spend have remained intact with many companies now becoming increasingly dependent on the efficiencies provided by technology and the need for innovationKforce, to support business strategies and sustain relevancy in today’s rapidly changing marketplace.

Flex representedRevenue
Flex revenue represents approximately 96% of total Kforce revenues, respectively.revenue over the last three fiscal years. We provide our clients with qualified individuals (“consultants”) on a temporary basis when it is determined that they have the appropriate skills and experience and are the right match for our clients. We recruitutilize a diversified set of recruitment platforms and databases to identify consultants from the job boards, Kforce.com, social media networks and passive candidate marketing, where we identify individuals who are currently employed and not actively seeking another position.employment. These consultants can either be directly employed by Kforce, qualified independent contractors or foreign nationals sponsored by Kforce. Our success is dependent upon our internal employees’ (“associates”) ability to: (1) acknowledge, understand and participate in creating solutions for our clients’ needs; (2) determine and understand the experience and capabilities of the consultants being recruited; and (3) deliverensure excellence in delivering and managemanaging the client-consultant relationship to the satisfaction of both our clients and our consultants.relationship. We believe proper execution by our associates and our consultants directly impacts the longevity of the assignments, increases the likelihood of being able to generategenerating repeat business with our clients and fosters a better experience for our consultants, which has a direct correlation to their redeployment.

The key drivers of Flex revenuesrevenue are driven by the number of totalconsultant assignments and billable hours, billedthe bill rate per hour and, pre-established bill rates.to a limited extent, the amount of billable expenses incurred by Kforce. Our Flex gross profit is determined by deducting consultant pay,related costs of employment for consultants, including compensation, payroll taxes, certain fringe benefits and other relatedsubcontractor costs from Flex revenues.revenue. Associate commissions, relatedand field management compensation, payroll taxes and other compensation andfringe benefits as well as field management compensation are included in selling, general and administrative expenses (“SG&A”), along with other customary costs such as administrative and corporate compensation.costs. The Flex business model involves attempting to maximize the number of billable consultant hours and bill rates, while managing consultant pay rates and benefit costs, as well as compensation and benefits for our core associates. Flex revenues also includes revenues for our GS segment. These revenues involve providing longer-term contract services to the customer primarily on a time-and-materials basis.
Direct Hire Revenue
Our Direct Hire business is a significantly smaller, yet important, part of our business that involves locating qualified individuals (“candidates”) for permanent placement with our clients. Direct Hire revenue represents less than 4% of total revenue over the last three fiscal years; although it is a smaller portion of our business, it continues to be an important capability in ensuring that we can meet the talent needs of our clients through whatever means they prefer. We primarily perform theserecruit candidates using methods that are consistent with Flex consultants. Candidate searches are generally performed on a contingency basis; thus,basis (as opposed to a retained search), therefore fees are only earned if the candidates are ultimately hired by our clients. The typical fee structure is based upon a percentage of the placed individual’scandidate’s annual compensation in their first year of employment, which is known or can be estimated at the time of placement. We recruit candidates using methods that

Industry Overview
The specialtyprofessional staffing industry is made up of thousands of companies, most of which are small local firms providing limited service offerings to a relatively small local client base. Based on aA report published by SIA in 2016 regarding the largest staffing firms in the United States, we estimate2018 indicated that Kforce is one of the 10 largest publicly-traded specialty staffing firms in the U.S. According to a report published by the SIA in June 2016, 134 companies reported at least $100 million in U.S. staffing revenues in 2015 and these companies represented an estimated 56.8% of the total market.

Based upon previous economic cycles experienced by Kforce, we believe that times of sustained economic recovery generally stimulate demand for additional temporary workers in the U.S. workers and, conversely, an economic slowdown results in a contraction in demand for additional temporary workers in the U.S. workers. From an economic standpoint, temporary employment figures and trends are important indicators of staffing demand, which continued to be positive during 2016,2018, based on data published by the Bureau of Labor Statistics (“BLS”) and SIA. The penetration rate (the percentage of temporary staffing to total employment)employment (penetration rate) and unemployment rate was 2.1% and 3.9%, respectively, in December 20162018. Total non-farm employment was at 2.04%, a slight decline from the December 2015 high of 2.06%. While the health of the macro-employment picture was uncertain at times during 2016, it generally continuously improved, with the unemployment rate at 4.7%up 1.8% year-over-year as of December 2016,2018, and non-farm payroll expanding an average of approximately 180,000 jobs per month in 2016. Also,temporary help employment was up 3.3% year-over-year. In addition, the college-level unemployment rate, which we believe serves as a proxy for professional employment and therefore aligns well with the candidateconsultant and consultantcandidate population that Kforce most typically serves, was at 2.5%2.1% in December 2016.2018. Further, we believe that the unemployment rate in the specialties we serve, especially in certain technology skill sets, is lower than the published averages, which we believe speaks to the demand environment in which we are operating. Management believes that
According to a SIA in September 2018, the tepid growth in the overall U.S. economy seen through much of 2016, the recent change in administration, and the increasing costs and government regulation of employment may be driving a secular shift to an increased use of temporary staff as a percentage of total workforce as employers may be reluctant to increase permanent hiring. If the penetration rate of temporary staffing experiences growth in the coming months and years, we believe our Flex revenues may grow even in a relatively modest growth macro-economic environment. Kforce remains optimistic about the growth prospects of thetechnology temporary staffing industry the penetration rate, and in particular, our revenue portfolio; however, the economic environment includes considerable uncertaintyfinance and volatility and therefore no reliable predictions can be made about the general economy, the staffing industry as a whole, or specialty staffing in particular.
According to an industry forecast published by SIA in September 2016, the U.S.accounting temporary staffing industry generated estimated revenues of $103.7 billion in 2013, $109.2 billion in 2014 and $115.7 billion in 2015, and hasare expected to generate projected revenues of $120.0$32.0 billion and $8.5 billion, respectively, in 20162019 and $124.8 billion in 2017. Basedbased on these projected revenues, of $120.0 billion for the U.S. temporary staffing industry, this would put the Firm’s overallour current market share atis approximately 1%. Therefore, our3% and 4%, respectively. Our business strategies are sharply focused around expanding our share of the U.S. temporary staffing marketindustry and further penetrating our existing clients’ staffinghuman capital needs.
Business Strategies
Our primary goalsobjectives are to enhancedriving long-term shareholder value by achieving above-market revenue growth, as compared to our peers in the segments in which we are focused, making prudent investments to enhance efficiency and effectiveness within our operating model and efficiency and generating improvedsignificantly improving levels of operating profitability. We believe the following strategies will help us achieve our goals.objectives.
Invest in Revenue-GeneratingImproving Productivity of our Talent. We continuebelieve that it is critical to focus on providingprovide our talentassociates with the necessaryhigh quality tools to be more effectiveeffectively and efficient in performingefficiently perform their roles, and to better evaluate our business opportunities and allow us to elevateadvance the value we are bringingbring to our clients and candidates. This includes enhancingconsultants. We continue to enhance our sales methodologymethodologies and trainingprocesses in ways we believe will allow us to better evaluate and shape business opportunities with our clients as well as train our sales associates to engage in more strategic conversationson our consistent and shape solutions with our clients. Weuniform methodology.

During 2018, we completed the initial rolloutdeployment of a new time and expense application for our sales transformation initiative in the fourth quarter of 2016consultants and willclients as well as a new expense application for our associates. In addition, we continue to make progress on ensuring it is fully engrained within the Firm. We also expect to enhance our delivery methodology and training of our delivery associates. This includes our national delivery team, which focuses on quality and speed of delivery servicesenhancements to our clients with demands for high volume staffing. Additionally, the Firm expects to continue to selectively hirebusiness and allocate revenue-generating talent in markets, products, industries and clients that present us with the greatest opportunity for profitable revenue growth.
Enhanced Customer Focus. During 2016, Kforce consolidateddata intelligence capabilities as well as our sales and delivery organization under a single leader, our Chief Operations Officer, and certain revenue-enabling support functions were realigned in an effort to allow us to more effectively compete for business, particularly with our largest customers. We believe the new alignment, coupled with the rebalancing of our sales and delivery talent through a disproportionate investment in sales talent, will enable us to allocate additional sales talent to provide exceptional service to our largest customers with whom we have long-term relationships. In order to achieve greater penetration within each of our largest accounts, we work to foster an understanding of our clients’ human capital needs holistically while building a consultative partnership rather than a transactional client relationship.
We strive to differentiate ourselves by working closely with our clients to understand their needs and maximize their return on human capital. Finding the right match for both our clients and consultants is our ultimate priority. The placement of our highly skilled consultants requires operational and technical skill to effectively recruit and evaluate personnel, match them to client needs, and manage the resulting relationships. We believe the proper placements of consultants with the right clients will serve to balance the desire for optimal volume, rate, effort and duration of assignment, while ultimately maximizing the benefit for our clients, consultants and the Firm. In addition, Kforce’s ability to offer flexible staffing solutions, coupled with our permanent placement capability, offers the client a broad spectrum of specialty staffing services.

Leverage Technology Infrastructure. We have made significant progress toward a rollout of our new customer relationship management system. We also began investing in a new talent relationship management system which incorporatesthat we expect will better leverage our enhanced sales methodology to reinforce execution. This rollout is a major piecedelivery strategies and processes and improve our capabilities. These investments are part of a multi-year effort to replace and upgrade our technology tools to equip our talented associates with significantly improved capabilities to deliver exceptional service to our clients, enhanceconsultants and candidates and improve the productivity of our associates and accelerate associate ramp-up. Asthe scalability of our organization.
Enhancing our Client Relationships. We strive to differentiate ourselves by working collaboratively with our clients to better understand their business challenges and help them attain their organizational objectives. This collaboration focuses on building a consultative partnership rather than a transactional client relationship, which increases the intimacy with our clients and improves our ability to offer higher value and a broader array of services and support to our clients. To accomplish this, we look intoalign our revenue-generating talent with the future, we expectappropriate clients based on their experience with markets, products and industries.
We measure our success in building long-lasting relationships with our clients using staffing industry benchmarks and surveys conducted by a specialized, independent third-party provider. Our client ratings compare very favorably against staffing industry averages and give us helpful insights directly from our clients on how to continue improving our technology infrastructure and surrounding processes to generate additional operating leverage as we grow, enhance flexibility in meeting our clients' increasing needs and improve the effectiveness of our associates.
Retain our Great People. A significant focus of Kforce is on the retention of our tenured and top performing associates. We ended fiscal 2016 with a strong, streamlined management, revenue-generating, and revenue-enabling teams, which we believe will continue to enhance our ability to achieve future profitable growth.

We are focused on effective and efficient processes and effective consultant care processes, such as onboarding, frequenttools to find and ongoing communicationattract prospective consultants, matching them to a client assignment and programssupporting them during their tenure with Kforce. Our success in this regard would be expected to redeploy our consultants in a timely fashion.

Competition
We operate in a highly competitive and fragmented specialty staffing services industry withincomprised of large national and local staffing firms in each of our reporting segments. We face substantial competition from large national firms and local specialty staffing firms. The local firms are typically operator-owned, and each market generally has one or more significant competitors. We also face competition from national clerical and light industrial staffing firms, and national and regional accounting, consulting and advisory firms that also offer certain specialtyboth solutions and staffing services. WeHowever, we believe however, that our U.S. geographic presence, diversifiedconcentration of service offerings in areas of greatest demand (especially technology), national delivery teams, enhanced sales methodology, focus on consistent servicedelivery channels for foreign consultants, longevity of our brand and deliveryreputation in the market, along with our dedicated compliance and effective job order prioritizationregulatory infrastructure, all provide a competitive advantage, particularly withadvantage.
Many clients that have operations in multiple geographic markets. In addition, we believe that our service offerings are primarily concentrated in areas with significant growth opportunities in both the short and long term.
In addition, many companies utilize Managed Service Providers (“MSP”) or Vendor Management Organizations (“VMO”) for the management and purchaseprocurement of staffing services. Generally, MSPs and VMOs are organizations that standardize processes through the use of Vendor Management Systems (“VMS”), which are tools used to aggregate spend and measure supplier performance. VMSs can also be provided through independent providers. Typically, MSPs, VMOs and/or VMS providers charge staffing firms administrative fees ofranging from 1% to 4% of total service revenues, and these fees are usually recorded by staffing firms as a costrevenue. In addition, the aggregation of services thereby compressing profit margins. Whileby MSPs for their clients into a single program can result in significant buying power and, thus, pricing power. Therefore, the use of MSPs by our clients has, in certain instances, resulted in margin compression. Kforce does not currently provide MSP or VMO services directly to its clients,our clients; rather, our strategy ishas been to work with MSP, VMOMSPs, VMOs and VMS providers that enable us to best extend our Flex staffing services to current and prospective clients.
Kforce believesWe believe that the availabilityprincipal elements of competition in our industry are quality and qualityavailability of associates, candidates and consultants, level of service, effective monitoring of job performance, scope of geographic service and compliance orientationorientation. To attract consultants and price are the principal elements of competition in our industry. We believe that availability of quality associates, candidates, and consultants is especially important. In order to attract candidates and consultants, we place emphasis uponemphasize on our ability to provide competitive compensation and benefits, quality and varied assignments, scheduling flexibility and permanent placement opportunities, all of which are important to Kforce being the “Employeremployer of Choice.”choice. Because personnelindividuals pursue other employment opportunities on a regular basis, it is important that we respond to market conditions affecting these individuals and focus on our consultant carerelationship objectives. Additionally, in certain markets, and in response to economic softening, we have experienced significant pricing pressure as a result of our competitors’ pricing strategies. Although we believe we compete favorably with respect to these factors, we expect competition and pricing pressure to continue, which may result in us not being able to effectively compete or choosing to not participate in certain business that does not meet our profitability standard.

Regulatory Environment
Staffing firms are generally subject to one or more of the following types of government regulations: (1) regulation of the employer/employee relationship, between a firm and its staff, such as wage and hour regulations, tax withholding and reporting, immigration regulations, social security and other retirement, anti-discrimination, employee benefits and workers’ compensation regulations; (2) registration, licensing, recordkeeping and reporting requirements; (3) worker classification regulationsregulations; and (4) substantive limitations on their operations.
In providing staffing and solution services to the Federal Government, we must comply with complex laws and regulations relating to the formation, administration and performance of Federal Government contracts. These laws and regulations create compliance risk and affect how we do business with our federal agency clients, and may impose addedadditional costs on our business.
In the increasingly stringentBecause we operate in a complex regulatory environment, one of our top priorities is compliance. As we continue to evolve our infrastructure, compliance remains a primary focus. For more discussion of the potential impact that the regulatory environment could have on Kforce’s financial results, seerefer to Item 1A. Risk Factors below.Factors.
Operating Employees and Personnel
As of December 31, 2016,2018, Kforce employed nearly 2,800approximately 2,400 associates and had more than 11,80011,400 consultants on assignment providing flexible staffing services and solutions to our clients. Approximately 91%92% of the consultants are employed directly by Kforce (“Flexible Employees”);Kforce; the balanceother 8% consists of individuals who are employed by other entities (“Independent Contractors”) that provide their employees as subcontractors to Kforce for assignment to Kforce’s clients.qualified independent contractors. As the employer, Kforce is responsible for the employer’s share of applicable social security taxes (“FICA”), federal and state unemployment taxes, workers’ compensation insurance and other direct labor costs relating to our employees. We offer access to various health, life and disability insurance programs and other benefits for our employees. We have no collective bargaining agreements covering any of our employees, have never experienced any material labor disruption, and are unaware of any current efforts or plans to organize any of our employees.
Insurance
Kforce maintains a number of insurance policies including general liability, automobile liability, workers’ compensation and employers’ liability; each withliability, liability for certain foreign exposure, umbrella and excess liability, coverage. We also maintain workers’ compensation, fidelity,property, crime, fiduciary, directors and officers, employment practices liability, cybersecurity, professional liability and excess health insurance and employment practices liability policies.coverage. These policies provide coverage subject to their terms, conditions, limits of liability and deductibles, for certain liabilities that may arise from Kforce’s operations. There can be no assurance that any of the above policies will be adequate for our needs or that we will maintain all such policies in the future.

ItemITEM 1A.     Risk Factors.RISK FACTORS.
The U.S. professional staffing industry in which we operate is significantly affected by fluctuations in general economic and employment conditions.
Demand for staffing services is significantly affected by the general level of economic activity and employment in the U.S. Based upon previous economic cycles that Kforce has experienced, we believe that times of sustained economic recovery generally stimulate demand for additional U.S. temporary workers and, conversely, an economic slowdown results in a contraction in demand for additional U.S. temporary workers. Even without uncertainty and volatility, it is difficult for us to forecast future demand for our services due to the inherent difficulties in forecasting the strength of economic cycles, and the short-term nature of many of our agreements. As economic activity slows, companies may defer projects for which they utilize our services or reduce their use of temporary employees before laying off permanent employees. In addition, an economic downturn could result in a reduction in the temporary staffing penetration rate, an increase in the unemployment rate and a deceleration of growth in the segments in which we and our clients operate. We may also experience more competitive pricing pressures during periods of economic downturn. Any substantial economic downturn in the U.S. or global impact on the U.S. could have a material adverse effect on our business, financial condition, and results of operations.
Kforce faces significant employment-related legal risk.
Kforce employs people internally and in the workplaces of our clients. An inherent risk of such activity includes possible claims of or relating to discrimination and harassment claims;harassment; wrongful termination; violations of employment rights related to employment screening or privacy issues; classificationmisclassification of workers as employees or independent contractors; violations of wage and hour requirements;requirements and other labor laws; employment of illegal aliens; criminal activity; torts; breach of contract; failure to protect confidential personal information; intentional criminal misconduct; misuse or misappropriation of client intellectual property; employee benefits; or other claims. In some cases, we are contractually obligated to indemnify our clients against such risks. Such claims may result in negative publicity, injunctive relief, criminal investigations and/or charges, civil litigation, payment by Kforce of defense costs, monetary damages or fines that may be significant, discontinuation of client relationships or other material adverse effects on our business. To reduce our exposure, we maintain policies, procedures and guidelines to promote compliance with laws, rules, regulations and regulationsbest practices applicable to our business. Even claims without merit could cause us to incur significant expense or reputational harm. We also maintain insurance coverage for professional malpractice liability, fidelity, employment practices liability, and general liability in amounts and with deductibles that we believe are appropriate for our operations. However, the failure of any of our personnel to observe our policies and guidelines could result in negative publicity, injunctive relief, criminal investigation and/or charges, payments of monetary damages or fines, or other material adverse effects on our business. In addition, our insurance coverage may not cover all potential claims against us, may require us to meet a deductible or may not continue to be available to us at a reasonable cost. In this regard, we face various employment-related risks not covered by insurance, such as wage and hour laws and employment tax responsibility. U.S. Courtscourts in recent years have been receiving large numbers of wage and hour class action claims alleging misclassification of overtime-eligible workers and/or failure to pay overtime-eligible workers for all hours worked.
Kforce may be exposed to unforeseeable negative acts by our personnel that could have a material adverse effect on our business.
An inherent risk of employing people internally and in the workplace of other businesses is that many of these individuals have access to client information systems and confidential information. SuchThe risks of such activity includesinclude possible acts of errors and omissions; intentional misconduct; release, misuse or misappropriation of client intellectual property, confidential information, personally identifiable information, funds, or other property; cybersecurity breaches affecting our clients and/or us; or other acts. These risks are particularly significant in our government business. Such acts may result in negative publicity or other material adverse effects on our business. In addition, these occurrences may give rise to litigation, which could be time-consuming and expensive. To reduce our exposure, we maintain policies, procedures and insurance coverage for types and amounts we believe are appropriate in light of the aforementioned exposures. There can be no assurance that the corporate policies and practices we have in place to help reduce our exposure to these risks will be effective or that we will not experience losses as a result of these risks. In addition, our insurance coverage may not cover all potential claims against us, may require us to meet a deductible or may not continue to be available to us at a reasonable cost.
Kforce may not be able to recruit and retain qualified consultants and candidates.
Kforce depends upon the abilities of its staff to attract and retain consultants and candidates, particularly technical, professional, and cleared government services individuals, who possess the skills and experience necessary to meet the staffing requirements of our clients. We must continually evaluate and upgrade our methods of attracting qualified consultants and candidates to keep pace with changing client needs and emerging technologies. We expect significant competition for individuals with proven technical or professional skills for the foreseeable future. The U.S. professional staffing industry in which we operate is significantly affected by fluctuations in general economicsupply of available consultants and employment conditions.
Demand for staffing services is significantly affected by the general level of economic activity and employment in the U.S. Based upon previous economic cycles experienced by Kforce, we believe that times of sustainedcandidates has been constrained during this economic recovery, generally stimulate demand for additional U.S. workers and, conversely, an economic slowdown results in a contraction in demand for additional U.S. workers. Even without uncertainty and volatility, it is difficult for us to forecast future demand for our services due to the inherent difficulties in forecasting the strength of economic cycles, and the short-term nature of many of our agreements, other thanespecially in our GSTech segment. AsIf qualified individuals are not available to us in sufficient numbers and upon economic activity slows, companies may defer projects for which they utilize our services or reduce their use of temporary employees before laying off permanent employees. In addition, an economic downturn could result in a reduction in the temporary staffing penetration rate, an increase in the unemployment rate and a deceleration of growth in the segments in which we and our clients operate. We may also experience more competitive pricing pressures during periods of economic downturn. Since approximately 99% of our revenue is generated by operations in the U.S., any substantial economic downturn in the U.S. or global impact on the U.S.terms acceptable to us, it could have a material adverse effect on our business, financial condition,business.

Our failure to keep pace with technological change in our industry will potentially place us at a competitive disadvantage.
Our future success may depend on our ability to successfully keep pace with technological changes and results of operations.
Kforce may be adversely affected by government regulation of the staffing business and of the workplace.
advances occurring across our industry. Our business is subjectreliant on a variety of systems and technologies, including those that support candidate searching and matching, hiring and tracking, order management, billing, and client data analytics. Our success may depend on our ability to regulationkeep pace with rapid technological changes in the development and licensingimplementation of these services. If our systems become outdated, or if our investments in many states. There cantechnology fail to provide the expected results, then we may be no assurance thatunable to maintain our technological capabilities relative to our competitors and our business could be negatively affected.
Cybersecurity risks and cyber incidents could adversely affect our business and disrupt operations.
Cyberattacks or other breaches of network or information technology used by our associates and consultants, as well as risks associated with compliance on data privacy could adversely affect on our systems, services, operations and financial results. These attacks include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. While we will be ablehave policies, procedures and systems in place to continuedetect, prevent and deter cyberattacks or other breaches of our networks, techniques used to obtain all necessary licensesunauthorized access or approvalscause system interruption change frequently and may not immediately produce signs of intrusion. As a result, we may be unable to anticipate these incidents or that the cost of compliance willtechniques, timely discover them, or implement adequate preventative measures. We maintain cyber risk insurance, but this insurance may not provebe sufficient to be material. If we fail to comply, such failure could materially adversely affect Kforce’s financial results.
A large partcover all of our losses from any future breaches of our systems or information. Our information technology may not provide sufficient protection, and as a result we may lose significant information about us, our employees or clients. Other results of these incidents could include, but are not limited to, increased cybersecurity protection costs, litigation, regulatory penalties, monetary damages, and reputational damage adversely affecting client or investor confidence.
Declines in business entails employing individuals onor a temporary basis and placing such individuals in clients’ workplaces. Increased government regulationloss of the workplace or of the employer/employee relationshipour major client accounts could have a material adverse effect on Kforce. For example, changes to government regulations, including changes to statutory hourly wageour revenues and overtime regulations, could adversely affect the Firm’s results of operations by increasing its costs.financial results.

ReclassificationPart of our independent contractors by tax or regulatory authorities could materiallybusiness strategy includes enhancing our service offerings and adversely affect our business model and could requirerelationships with large consumers of temporary staffing, which is intended to enable us to payprofitably grow our revenues with these clients. However, it also creates the potential for concentrating a significant retroactive wages, taxesportion of our revenues among our largest clients and penalties.
We utilize individualsexposes us to provideincreased risks arising from decreases in the volume of business from, the pricing of business with, or the possible loss of business with these clients. Organizational changes occurring within those clients, or a deterioration of their financial condition or business prospects, could reduce their need for our services in connection with our business as third-party independent contractors rather than our direct employees. There is a heightened state and federal scrutiny of independent contractor relationships, which could adversely affect us given that we utilize independent contractors to perform our services. An adverse determination of the independent contractor status of these subcontracted personnel could result in a substantial tax or other liabilities to us.significant decrease in the revenues we derive from those clients and could have a material adverse effect on our financial results.
Our collection, use and retention of personally identifiable information of our associates and consultants create risks that may harm our business.
In the ordinary course of our business, we collect and retain personal information of our associates and consultants and their dependents including, without limitation, full names, social security numbers, addresses, birth dates, and payroll-related information. We use commercially available information security technologies to protect such information in digital format. We also use security and business controls to limit access to such information.information and continually monitor our systems for potential breaches. However, employeesas our reliance on technology has increased so have the risks posed to our systems, both internal and those managed by third party service providers. It is possible that the controls in place will not be able to prevent the improper disclosure of personally identifiable information of our associates and consultants in the event of a computer virus, system breach or cyberattack, particularly in light of the increasing sophistication of perpetrators. Employees or third parties (including third parties with substantially greater resources than our own; for example,own, e.g. foreign governments) may be able to circumvent theseour security measures and acquire or misuse such information, resulting in breaches of privacy andbreaches, errors in the storage, use or transmission of such information.information, and an interruption to our operations. Privacy breaches may require notification and other remedies, which can be costly, and which may have other serious adverse consequences for our business, including regulatory penalties and fines, claims for breach of contract, claims for damages, adverse publicity, reduced demand for our services by clients and/or Flex employment consultants, harm to our reputation, and regulatory oversight by state or federal agencies.
The possession and use of personal information and data in conducting our business subjects us to legislative and regulatory burdens. We may be required to incur significant expenses to comply with mandatory privacy and security standards and protocols imposed by law, regulation, industry standards or contractual obligations.
Kforce may be adversely affected by government regulation of the staffing business and of the workplace.
Our business is subject to regulation and licensing in many states. There can be no assurance that we will be able to continue to obtain all necessary licenses or approvals or that the cost of compliance will not prove to be material. If we fail to comply, such failure could materially adversely affect Kforce’s financial results.

A large part of our business entails employing individuals on a temporary basis and placing such individuals in clients’ workplaces. Increased government regulation of the workplace or of the employer/employee relationship could have a material adverse effect on Kforce. For example, changes to government regulations, including changes to statutory hourly wage and overtime regulations, could adversely affect the Firm’s results of operations by increasing its costs. Due to the substantial number of state and local jurisdictions in which we operate and the widening disparity among state and local laws, there also is a risk that we may be unaware of, or unable to adequately monitor, actual or proposed changes in, or the interpretation of, the laws or governmental regulations of such states and localities. Any delay in our compliance with changes in such laws or governmental regulations could result in potential fines, penalties, or other sanctions for non-compliance.
Reclassification of our independent contractors by tax or regulatory authorities could materially and adversely affect our business model and could require us to pay significant retroactive wages, taxes and penalties.
We utilize individuals to provide services in connection with our business as qualified third-party independent contractors rather than our direct employees. Heightened state and federal scrutiny of independent contractor relationships could adversely affect us given that we utilize independent contractors to perform our services. An adverse determination related to the independent contractor status of these subcontracted personnel could result in a substantial tax or other liabilities to us.
Significant increases in wages or payroll-related costs could adversely affect Kforce’s business.
Significant increases in wages or the effective rates of any payroll-related costs could have a material adverse effect on Kforce. Kforce is required to pay a number of federal, state, and local payroll and related costs or provide certain benefits such as paid time off, sick leave, unemployment taxes, workers’ compensation and insurance premiums and claims, FICA, and Medicare, among others, related to our employees. Costs could also increase as a result of health care reforms or the possible imposition of additional requirements and restrictions related to the placement of personnel. We may not be able to increase the fees charged to our clients in a timely manner or in a sufficient amount to cover these potential cost increases.
Kforce may be adversely affected by immigration restrictions.restrictions and reform.
Our Tech businesssegment utilizes a significant number of foreign nationals employed by us on work visas, primarily under the H-1B visa classification. The H-1B visa classification that enables U.S. employers to hire qualified foreign nationals is subject to legislative and administrative changes, as well as changes in the application of standards and enforcement. Immigration laws and regulations can be significantly affected by political developments and levels of economic activity. Current and future restrictions on the availability of such visas could restrain our ability to employ the skilled professionals we need to meet our clients’ needs, which could have a material adverse effect on our business. The U.S. Citizenship and Immigration Service (“USCIS”) continues to closely scrutinize companies seeking to sponsor, renew or transfer H-1B status, including Kforce and Kforce’s subcontractors and has issued internal guidance to its field offices that appears to narrow the eligibility criteria for H-1B status in the context of staffing services. In addition to USCIS restrictions, certain aspects of the H-1B program are also subject to regulation and review by the U.S. Department of Labor and U.S. Department of State, which have recently increased enforcement activities in the program. A narrow interpretation and vigorousVigorous enforcement and/or legislative or executive action relating to immigration including legislation intended to reform existing immigration law or actions by executive order, could adversely affect our ability to obtain foreign national labor and/recruit or renew existingretain foreign national consultants, on assignment, and couldconsequently, reduce our supply of skilled consultants and candidates and subject us to fines, penalties and sanctions. There can be no assurance that we will be able to keepsanctions, or replace all foreign nationals currently on assignment, or continue to hire foreign national talent at the same rates asresult in the past.
Kforce may not be able to recruitincreased labor and retain qualified candidates and consultants.
Kforce depends upon the abilities of its staff to attract and retain candidates and consultants, particularly technical, professional, and cleared government services individuals, who possess the skills and experience necessary to meet the staffing requirements of our clients. We must continually evaluate and upgrade our base of available qualified candidates and consultants to keep pace with changing client needs and emerging technologies. We expect significant competition for individuals with proven technical or professional skills for the foreseeable future. The supply of available candidates and consultants has been constrained for the past few years. If qualified individuals are not available to us in sufficient numbers and upon economic terms acceptable to us, it could have a material adverse effect on our business.

compliance costs.
Kforce’s success depends upon retaining the services of its management team and key operating employees.
Kforce is highly dependent on its management team and expects that continued success will depend largely upon their efforts, expertise and abilities. The loss of the services of any key executive for any reason could have a material adverse effect uponon Kforce. Success also depends upon our ability to identify, develop,To attract and retain qualified operating employees; particularlyexecutives and other key employees (particularly management, client servicing, and consultant and candidate recruiting employees.employees) in a competitive marketplace, we must provide a competitive compensation package, including cash-based and equity-based compensation. Kforce expends significant resources in the recruiting and training of its employees, as the pool of available applicants for these positions is limited. The loss of someor any sustained attrition of our key operating employees could have a material adverse effect on our business, including our ability to establish and maintain client, consultant and candidate, professional and technical relationships.
Kforce maintains debt which exposes us to interest rate risk and contains restrictive covenants that could trigger prepayment of obligations or additional costs.
We have a credit facility consisting of a revolving line of credit of up to $170 million. Borrowings under the credit facility are secured by substantially all of the assets of the Firm, including the Firm’s corporate headquarters.
Adverse changes in credit markets, including increases in interest rates, could increase our cost of borrowing and/or make it more difficult to refinance our existing indebtedness. We may reduce our exposure to rising interest rates by entering into interest rate hedging arrangements, although those arrangements may result in us incurring higher interest expenses than we would incur without the arrangements. If interest rates increase in the absence of such arrangements, we will need to dedicate more of our cash flow from operations to make payments on our debt.
Kforce is subject to certain affirmative and negative covenants under the credit facility. Our failure to comply with such restrictive covenants could result in an event of default, which, if not cured or waived, could result in Kforce being required to repay the outstanding balance before the due date. We may not be able to repay our debt or if forced to refinance on terms not acceptable to us could have a material adverse affect on our results of operations and financial condition.
Declines in business or a loss of our major customer accounts could have a material adverse effect on our revenues and financial results.
Part of our business strategy includes enhancing our service offerings to our largest client accounts. This strategy is intended to enable us to profitably grow our revenues from our major customer accounts, however, it also concentrates a significant portion of our revenues among our largest clients and exposes us to increased risks arising from decreases in the volume of business from, or the possible loss of, those major customer accounts. Organizational changes occurring within those customers, or a deterioration of their financial condition or business prospects, could reduce their need for our services and result in a significant decrease in the revenues we derive from those customers and could have a material adverse effect on our financial results.
Kforce’s temporary staffing business could be adversely impacted by health care reform.
The Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010, and the rules and regulations thereunder (the “PPACA”), imposes mandatesrequirements and restrictions, including, but not limited to, guaranteed coverage requirements, prohibitions on individualssome annual and employers, requiring most individualsall lifetime limits on amounts paid on behalf of or to have health insurance. The PPACA assesses penaltiesour employees, increased restrictions on large employers that do not offer healthrescinding coverage, establishment of minimum requirements, the establishment of state insurance meeting certain coverage, value, or affordability standards to all full-time employees as defined under the PPACA.exchanges and essential benefit packages, and greater limitations on product pricing. Because the regulations governing the PPACA’s employer mandate are subject to interpretation, it is possible that Kforce may incur liability in the form of penalties, fines, or damages if the health plans we offer are subsequently found not to meet minimum essential coverage, affordability or minimum value standards, or if our method for determining eligibility for coverage is found inadequate or our clients seek indemnification for health care claims resulting from consultants working on client assignments. The cost of any such penalties, fines or damages could have a material adverse effect on Kforce’s financial and operating results.
New business initiatives and strategic changes may divert management’s attention from normal business operations, which could adversely affect our performance.
New business initiatives and strategic changes in the composition of our business mix can be a diversion to our management’s attention from other business concerns and disruptive to our operations, which could cause our business and results of operations to suffer materially. Acquisitions and new business initiatives could involve significant unanticipated challenges and risks, including the possibility that: they may not advance our business strategy; we may not realize our anticipated return on our investment; we may lose key personnel; we may retain unforeseen liabilities; we may experience difficulty in implementing initiatives or integrating acquired operations; or management's attention may be diverted from our other businesses. These events could cause material harm to our business, operating results, or financial condition.
Kforce maintains debt that exposes us to interest rate risk and contains restrictive covenants that could trigger prepayment of obligations or additional costs.
We have a credit facility consisting of a revolving line of credit of up to $300.0 million, subject to certain limitations. Borrowings under the credit facility are secured by substantially all of the tangible and intangible assets of the Firm, excluding the Firm’s corporate headquarters and certain other designated executed collateral.
Adverse changes in credit markets, including increases in interest rates, could increase our cost of borrowing and/or make it more difficult to refinance our existing indebtedness, if necessary. We have reduced our exposure to rising interest rates by entering into an interest rate hedging arrangement, although this and other arrangements may result in us incurring higher interest expenses than we would have otherwise incurred. If interest rates increase in the absence of such arrangements though, we would need to dedicate more of our cash flow from operations to service our debt.
Kforce is subject to certain affirmative and negative covenants under our credit facility. Our failure to comply with such restrictive covenants could result in an event of default, which, if not cured or waived, could result in Kforce being required to repay the outstanding balance before the due date. If this occurs, we may not be able to repay our debt or we may be forced to refinance on terms not acceptable to us, which could have a material adverse effect on our results of operations and financial condition.
Kforce depends on the proper functioning of its information systems.
Kforce is dependent on the proper functioning of information systems in operating our business. Critical information systems are used in every aspect of Kforce’s daily operations, most significantly, in the identification and matching of staffing resources to client assignments and in the client billing and consultant or vendor payment functions. Kforce’s information systems may not perform as anticipated and are vulnerable to damage or interruption including natural disasters, fire or casualty theft, technical failures, terrorist acts, cybersecurity breaches, power outages, telecommunications failures, physical or software intrusions, computer viruses, employee errors and similar events. Our corporate headquarters and data center are located in a hurricane-prone area although we have disaster recovery systems for some key information systems, such as billing and payroll, but not for all such key systems. Failure or interruption of our critical information systems may require significant additional capital and management resources to resolve, which could materially adversely affect our business. Additionally, many of our information technology systems and networks are cloud-based or managed by third parties, whose future performance and reliability we cannot control. The risk of a cyberattack or security breach on a third party carries the same risks to Kforce as those associated with our internal systems.  We seek to reduce these risks by performing vendor due diligence procedures prior to engaging with any third party vendor who will have access to sensitive data. Additionally, we require audits of the relevant third parties’ information technology processes on an annual basis. However, there can be no assurance that such parties will not experience cybersecurity breaches that could adversely affect our employees, customers and businesses or that our audit or diligence processes will successfully deter or prevent such breach.

Delays in collecting our trade accounts receivable could adversely affect our business.
We generate a significant amount of trade accounts receivable from our clients. Delays in payments owed to us could have a material adverse effect on our financial condition and cash flows generated by our business. Factors that could cause a delay include business failures, turmoil in the financial and credit markets, sluggish or recessionary U.S. economic conditions, our exposure to clients in high-risk sectors such as the financial services industry, declines in the credit worthiness of our clients, extension in payment terms with our clients and declines in the business of our clients.
Adverse results in tax audits or interpretations of tax laws could adversely impact our business.
Kforce is subject to periodic federal, state and local tax audits for various tax years. We also need to comply with new, evolving or revised tax laws and regulations. The Tax Cuts and Jobs Act enacted in December 2017 continues to require significant interpretation; as additional regulatory guidance is issued and we continue to analyze the application of the new law, we may be required to refine our estimates, which could materially affect our tax obligations and effective tax rate. Although Kforce attempts to comply with all taxing authority regulations, adverse findings or assessments made by taxing authorities as the result of an audit could have a material adverse effect on Kforce.
Due to inherent limitations, there can be no assurance that our system of disclosure and internal controls and procedures will be successful in preventing all errors and fraud, or in making all material information known in a timely manner to management.
Our management, including our CEO and CFO, does not expect that our disclosure controls and internal controls will prevent all errors and fraud. A control system, regardless of how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. 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, within Kforce have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control.
The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations, misstatements due to error or fraud may occur and not be detected.
We are exposed to intangible asset risk which could result in future impairment.
We regularly review our intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. We test goodwill and indefinite-lived intangible assets for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying value of the intangible assets may not be recoverable, include: macroeconomic conditions; industry and market considerations; increases in labor or other costs that have a negative effect on earnings and cash flows; negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; and other relevant entity-specific events, such as changes in key personnel, strategy, or customers,clients, and sustained decreases in share price. We may be required to record a charge in our financial statements, which could be material, during the period in which we determine an impairment of our acquired intangible assets has occurred, negatively impacting our financial results.

Significant legal actions could subject Kforce to substantial uninsured liabilities.
Professional service providers are subject to legal actions alleging malpractice, breach of contract and other legal theories. These actions may involve large claims and significant defense costs. We may also be subject to claims alleging violations of federal or state labor laws. In addition, we may be subject to claims related to torts, intentional acts, or crimes committed by our permanent employees or temporary staffing personnel. In some instances, we are contractually obligated to indemnify clients against such risks. A failure to observe the applicable standard of care, relevant Kforce or client policies and guidelines, or applicable federal, state, local or foreign laws, rules, and regulations could result in negative publicity, payment of fines, significant damage awards, or settlement expense. To reduce our exposure, we maintain insurance coverage for professional malpractice liability, fidelity, employment practices liability and general liability, in amounts and with deductibles that we believe are appropriate for our operations. Our insurance coverage, however, may not cover all claims against us or continue to be available to us at a reasonable cost.
Delays or defaults in collecting our trade accounts receivable could adversely affect our business.
We generate a significant amount of trade accounts receivable from our customers. Delays or defaults in payments owed to us could have a material adverse effect on our financial condition and results of operations. Factors that could cause a delay or default include business failures, turmoil in the financial and credit markets, sluggish or recessionary U.S. economic conditions, our exposure to customers in high-risk sectors such as the financial services industry, declines in the credit worthiness of our customers, and declines in the business of our customers.
Kforce depends on the proper functioning of its information systems.
Kforce is dependent on the proper functioning of information systems in operating its business. Critical information systems are used in every aspect of Kforce’s daily operations, most significantly, in the identification and matching of staffing resources to client assignments and in the customer billing and consultant or vendor payment functions. Kforce’s information systems are vulnerable to natural disasters (our headquarters and leased data center are located in a hurricane-prone area), fire or casualty theft, technical failures, terrorist acts, cybersecurity breaches, power loss, telecommunications failures, physical or software intrusions, computer viruses, and similar events. We have disaster recovery systems for some key information systems, such as billing and payroll, but not for all such key systems. If our critical information systems fail or are otherwise unavailable, we would have to accomplish these functions manually, which could prove difficult or impossible, causing a material adverse effect on our business. Many of our information technology systems and networks are cloud-based or managed by third parties, whose future performance and reliability we cannot control.
Cybersecurity risks and cyber incidents could adversely affect our business and disrupt operations.
Cyber attacks or other breaches of network or information technology used by our associates and consultants, as well as risks associated with compliance on data privacy could have an adverse effect on our systems, services, operations and financial results. These attacks include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. While we have policies, procedures and systems in place to detect, prevent and deter cyber attacks or other breaches of our networks, techniques used to obtain unauthorized access or cause system interruption change frequently and may not immediately produce signs of intrusion. As a result, we may be unable to anticipate these incidents or techniques, timely discover them, or implement adequate preventative measures. Our information technology may not provide sufficient protection, and as a result we may lose significant information about us or our employees or customers. Other results of these incidents could include, but are not limited to, increased cybersecurity protection costs, litigation and reputational damage adversely affecting customer or investor confidence.
Significant increases in payroll-related costs could adversely affect Kforce’s business.
Kforce is required to pay a number of federal, state, and local payroll and related costs or provide certain benefits such as paid time off, sick leave, unemployment taxes, workers’ compensation and insurance premiums and claims, FICA, and Medicare, among others, related to our employees. Significant increases in the effective rates of any payroll-related costs would likely have a material adverse effect on Kforce. Costs could also increase as a result of health care reforms or the possible imposition of additional requirements and restrictions related to the placement of personnel. We may not be able to increase the fees charged to our clients in a timely manner or in a sufficient amount to cover these potential cost increases.

Adverse results in tax audits could result in significant cash expenditures or exposure to unforeseen liabilities.
Kforce is subject to periodic federal, state, and local tax audits for various tax years. Although Kforce attempts to comply with all taxing authority regulations, adverse findings or assessments made by taxing authorities as the result of an audit could have a material adverse effect on Kforce.
Due to inherent limitations, there can be no assurance that our system of disclosure and internal controls and procedures will be successful in preventing all errors and fraud, or in making all material information known in a timely manner to management.
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 designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. 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, within Kforce have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control.
The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations, misstatements due to error or fraud may occur and not be detected.
Our business is dependent upon maintaining our reputation, our relationships and our performance.
The reputation and relationships that we have established and currently maintain with our customersclients are important to maintaining existing business and identifying new business. If our reputation or relationships were damaged, it could have a material adverse effectmaterially adversely affect on our operations. In addition, if our performance does not meet our customers’clients’ expectations, our revenues and operating results could be materially harmed.
Agreements may be terminated by clients and consultants at will and the termination of a significant number of such agreements could adversely affect our revenues.
Our agreements do not provide for exclusive use of our services, and clients are free to place orders with our competitors. Each consultant’s relationship with us is terminable at will. If clients terminate a significant number of our agreements and we are unable to generate new contracts, or a significant number of our consultants cease performing services for 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.

Kforce’s current market share may decrease as a result of limited barriers to entry for new competitors and discontinuation of clients outsourcing their staffing needs.
We face significant competition in the markets we serve, and there are limited barriers to entry for new competitors. The competition among staffing services firms is intense. Kforce competes for potential clients with providers of outsourcing services, systems integrators, computer systems consultants, temporary personnel agencies, search firms, and other providers of staffing services. Some of our competitors possess substantially greater resources than we do. From time to time, we experience significant pressure from our clients to reduce price levels. During these periods, we may face increased competitive pricing pressures and may not be able to recruit the personnel necessary to fulfill our clients’ needs. We also face the risk that certain of our current and prospective clients will decide to provide similar services internally, particularly if regulatory burdens are reduced.

Vendor management services are considered a competitor and increasing use by our clients could affect our relationships.
Increasingly, many clients and potential clients are retaining third parties to provide vendor management services. The third party, or vendor management company, is responsible for retaining companies that will provide temporary information technology personnel to the client. This results in Kforce contracting with such third parties and not directly with the end customer. This change can weaken Kforce’s relationship with its clients, which may make it more difficult to maintain and expand our business with existing customers. In addition, the agreements with vendor management companies are frequently structured as subcontracting agreements, with the vendor management company entering into a services agreement directly with the end customer. As a result, in the event of a bankruptcy of a vendor management company, Kforce’s ability to collect its outstanding receivables and continue to provide services could be adversely affected.
Kforce’s stock price may be volatile.
The market price of our stock has fluctuated substantially in the past and could fluctuate substantially in the future, based on a variety of factors, including our operating results, changes in general conditions in the economy, the financial markets, the staffing industry, or other developments affecting us, our clients, or our competitors; some of which may be unrelated to our performance.
In addition, the stock market in general, especially The NASDAQ Global Select Market (“NASDAQ”) tier, along with market prices for staffing companies, has experienced volatility that has often been unrelated to the operating performance of these companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating results.
Among other things, volatility in our stock price could mean that investors will not be able to sell their shares at or above the prices they pay. The volatility also could impair our ability in the future to offer common stock as a source of additional capital or as consideration in the acquisition of other businesses.
Provisions in Kforce’s articles and bylaws and under Florida law may have certain anti-takeover effects.
Kforce’s articles of incorporation and bylaws and Florida law contain provisions that may have the effect of inhibiting a non-negotiated merger or other business combination. In particular, our articles of incorporation provide for a staggered boardBoard of directorsDirectors (“Board”) and permit the removal of directors only for cause. Additionally, the Board may issue up to 15 million shares of preferred stock, and fix the rights and preferences thereof, without a further vote of the shareholders. In addition, certain of our officers and managers have employment agreements containing certain provisions that call for substantial payments to be made to such employees in certain circumstances after a change in control. Certain of these provisions may discourage a future acquisition of Kforce, including an acquisition in which shareholders might otherwise receive a premium for their shares. As a result, shareholders who might desire to participate in such a transaction may not have the opportunity to do so. Moreover, the existence of these provisions could have a negative effect onnegatively impact the market price of our common stock.

RISKS RELATED TO OUR GOVERNMENT BUSINESS
Our GS segment is substantially dedicated to contracting with and serving U.S. Federal Government agencies (the “Government Business”). In addition, Kforce supplies services to the Federal Government which poses additional risks to those mentioned previously. Federal contractors, including Kforce, face a number of risks, including but not limited to the following:

Our failure to comply with complex federal procurement laws and regulations could cause us to lose business, incur additional costs and subject us to a variety of penalties, including suspension and debarment from doing businesscontracting with the Federal Government.
We must comply with complex laws and regulations relating to the formation, administration, and performance of Federal Government contracts. These laws and regulations create compliance risk, affect how we do business with our federal agency clients, and may impose added costs on our business. If a government review, audit or investigation uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, harm to our reputation, suspension of payments, fines, and suspension or debarment from doing businesscontracting with Federal Government agencies.
The Federal Government also may reform its procurement practices or adopt new contracting rules and regulations, including cost accounting standards, thatwhich could be costly to satisfy or that could impact our ability to obtain new contracts. A failure to comply with all applicable laws and regulations could result in contract termination, price or fee reductions, or suspension or debarment from contracting with Federal Government agencies; each of which could lead to a material reduction in our revenues, cash flows and operating results.
Unfavorable government audit results could force us to refund previously recognized revenues and could subject us to a variety of penalties and sanctions.
Federal agencies can audit and review our performance on contracts, pricing practices, cost structure, incurred cost submissions and compliance with applicable laws, regulations, and standards. An audit of our work, including an audit of work performed by companies Kforce has acquired or may acquire, or subcontractors we have hired or may hire, could force us to refund previously recognized revenues.
If a government audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines, and suspension or debarment from doing business with Federal Government agencies. In addition, we could suffer serious harm to our reputation if allegations of impropriety were made against us, whether or not true.
We are dependent upon the ability of government agencies to administratively manage our contracts.
After we are awarded a contract and the contract is funded by the Federal Government, we are still dependent upon the ability of the relevant agency to administratively manage our contract. We can be adversely impacted by delays in the start-up of already awarded and funded projects, including delays due to shortages of acquisition and contracting personnel within the Federal Government agencies.
Changes in the spending policies or budget priorities of the Federal Government including the failure by Congress to approve budgets, raise the U.S. debt ceiling or avoid sequestration on a timely basis for the federal agencies we support could delay, reduce or stop federal spending and cause us to lose revenue or impair our intangible assets.
Changes in Federal Government fiscal or spending policies could materially adversely affect our Government Business; in particular, our business could be materially adversely affected by decreases in Federal Government spending. In addition, on an annual basis, Congress must approve, and the President must sign the appropriation bills that govern spending by each of the federal agencies we support. If Congress is unable to agree on budget priorities and is unable to appropriate funds or pass the annual budget on a timely basis, as has been the case in recent years,or a prolonged government shutdown were to occur (as happened recently), there may be delays, reductions or cessations of funding for our services and solutions. In addition, from time to time it has been necessary for Congress to raise the U.S. debt ceiling in order to allow for borrowing necessary to fund government operations. If that becomes necessary again and Congress fails to raise the debt ceiling on a timely basis, there may be delays, reductions or cessations of funding for our services and solutions. Furthermore, legislatively mandated cuts in federal programs, known as sequestration, could result in delays, reductions or cessation of funding for our services and solutions.

Unfavorable government audit results could force us to refund previously recognized revenue and could subject us to a variety of penalties and sanctions.
Federal agencies can audit and review our performance on contracts, pricing practices, cost structure, incurred cost submissions and compliance with applicable laws, regulations, and standards. An audit of our work, including an audit of work performed by companies Kforce has acquired or may acquire, or subcontractors we have hired or may hire, could force us to refund previously recognized revenues.
If a government audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines, and suspension or debarment from doing business with Federal Government agencies. In addition, we could suffer serious harm to our reputation if allegations of impropriety were made against us, regardless of the veracity.
We are dependent upon the ability of government agencies to administratively manage our contracts.
After we are awarded a contract and the contract is funded by the Federal Government, we are still dependent upon the ability of the relevant agency to administratively manage our contract. We can be adversely impacted by delays in the start-up of already awarded and funded projects, including delays due to shortages of acquisition and contracting personnel within the Federal Government agencies.
Competition is intense in the Government Business.
There is often intense competition to win federal agency contracts. The competitive bidding process entails substantial costs and management time to prepare bids and proposals for contracts that may not be awarded to us or may be split among competitors. Even when a contract is awarded to us, we may encounter significant expenses, delays, contract modifications or bid protests from competitors. If we are unable to successfully compete for new business or win competitions to maintain existing business, our operations could be materially adversely affected. Many of our competitors are larger and have greater resources, larger client bases and greater brand recognition than we do. Our larger competitors also may be able to provide clients with different or greater capabilities or benefits than we can provide.

Loss of our General Services Administration (“GSA”) Schedules or other contracting vehicles could impair our ability to win new business.
GSA Schedules constitute a significant percentage of revenues from our federal agency clients. If we were to lose one or more of these Schedules or other contracting vehicles, we could lose revenues and our operating results could be materially adversely affected. These Schedules or contracts typically have an initial term with multiple options that may be exercised by our government agency clients to extend the contract for successive periods of one or more years. We can provide no assurance that our clients will exercise these options.
Our failure to obtain and maintain necessary security clearances may limit our ability to perform classified work for government clients, which could cause us to lose business.
Some government contracts require us to maintain facility security clearances and require some of our employees to maintain individual security clearances. If our employees lose or are unable to timely obtain security clearances, or we lose a facility clearance, a government agency client may terminate the contract or decide not to renew it upon its expiration.
Our employees may engage in misconduct or other improper activities, which could harm our business.
Like all government contractors, we are exposed to the risk that employee fraud or other misconduct could occur. Misconduct by our employees could include intentional failures to comply with Federal Government procurement regulations, engaging in unauthorized activities, seeking reimbursement for improper expenses, or falsifying time records. Employee misconduct could also involve the improper use of our clients’ sensitive or classified information, which could result in regulatory sanctions against us and serious harm to our reputation. It is not always possible to deter employee misconduct, and precautions to prevent and detect this activity may not be effective in controlling such risks or losses, which could materially adversely affect our business.
Security breaches in sensitive government information systems could result in the loss of our clients and cause negative publicity.
Many of the systems we develop, install, and maintain involve managing and protecting information used in intelligence, national security, and other sensitive or classified government functions. A security breach in one of these systems could cause serious harm to our business, damage our reputation, and prevent us from being eligible for further work on sensitive or classified systems for Federal Government clients. We could incur losses from such a security breach that could exceed the policy limits under our insurance. Damage to our reputation or limitations on our eligibility for additional work resulting from a security breach in one of our systems could materially reduce our revenues.
Our employees may engage in misconduct or other improper activities, which could harm our business.
Like all government contractors, we are exposed to the risk that employee fraud or other misconduct could occur. Misconduct by our employees could include intentional or unintentional failures to comply with Federal Government procurement regulations, engaging in unauthorized activities, seeking reimbursement for improper expenses, or falsifying time records. Employee misconduct could also involve the improper use of our clients’ sensitive or classified information, which could result in regulatory sanctions against us and serious harm to our reputation. It is not always possible to deter employee misconduct, and precautions to prevent and detect this activity may not be effective in controlling such risks or losses, which could materially adversely affect our business.
Our failure to obtain and maintain necessary security clearances may limit our ability to perform classified work for government clients, which could cause us to lose business.
Some government contracts require us to maintain facility security clearances and require some of our employees to maintain individual security clearances. If our employees lose or are unable to timely obtain security clearances, or we lose a facility clearance, a government agency client may terminate the contract or decide not to renew it upon its expiration.
We are the prime contractor on many of our contracts and if our subcontractors fail to appropriately perform their obligations, our performance and our ability to win future contracts could be harmed.
For many of our contracts where we are the prime contractor, we involve subcontractors, which we rely on to perform a portion of the services that we must provide to our customers.clients. There is a risk that we may have disputes with our subcontractors, including disputes regarding the quality and timeliness of work performed or customerclient concerns about the subcontractor’s performance. In addition, the contracting parties on which we rely may be affected by changes in the economic environment and constraints on available financing to meet their performance requirements or provide needed supplies on a timely basis. A failure by one or more of those contracting parties to provide the agreed-upon supplies or perform the agreed-upon services on a timely basis may affect our ability to perform our obligations.

We are the subcontractor on many of our contracts and if we, or the applicable prime contractors, fail to appropriately perform our and their obligations, our financial condition may be harmed.
For many of our contracts, we are a subcontractor; therefore, we rely on the applicable prime contractor to secure contracts when they are put up for bid for a renewal or a new contract.  There is a risk that the applicable prime contractor is unable to secure such bids for a number of reasons, including the prime contractor’s quality and timeliness of services, financial condition, and relationships with the Federal Government.  In addition, there are risks that we are unable to provide such subcontractor services with the quality and timeliness demanded by the prime contractor or the ultimate end-client.  Any failure by the applicable prime contractor to secure contracts or by us to perform adequately could materially adversely affect our business.

On May 27, 2010, we acquiredWe own our corporate headquarters in Tampa, Florida, which is approximately 128,000 square feet of space. Borrowings under Kforce’s credit facility are secured by substantially all of the assets of the Firm, including the Firm’s corporate headquarters. In addition, as of December 31, 2016,2018, we leased approximately 340,000325,000 square feet of total office space for our 61in approximately 60 field offices which are located throughout the U.S., with lease terms ranging from three to five-yearsseven years, although a limited number of leases contain short-term renewal provisions that range from month-to-month to one year. We also lease an office in Manila, Philippines, which is approximately 17,000 square feet of space.
Although additional field offices may be established based on the requirements of our operations, we believe that our facilities are adequate for our current needs, and we do not expect to materially expand or contract our facilities in the foreseeable future.
ItemITEM 3.     Legal Proceedings.LEGAL PROCEEDINGS.
We are involved in legal proceedings, claims and administrative matters that arise in the ordinary course of our business. We have made accruals with respect to certain of these matters, where appropriate, that are reflected in our consolidated financial statements but are not, individually or in the aggregate, considered material. For other matters for which an accrual has not been made, we have not yet determined that a loss is probable, or the amount of loss cannot be reasonably estimated. While the ultimate outcome of the matters cannot be determined, we currently do not expect that these proceedings and claims, individually or in the aggregate, will have a material effect on our financial position, results of operations, or cash flows. The outcome of any litigation is inherently uncertain, however, and if decided adversely to us, or if we determine that settlement of particular litigation is appropriate, we may be subject to liability that could have a material adverse effect on our financial position, results of operations, or cash flows. Kforce maintains liability insurance in amounts and with such coverage and deductibles as management believes is reasonable. The principal liability risks that Kforce insures against are workers’ compensation, personal injury, bodily injury, property damage, directors’ and officers’ liability, errors and omissions, cyber liability, employment practices liability and fidelity losses. There can be no assurance that Kforce’s liability insurance will cover all events or that the limits of coverage will be sufficient to fully cover all liabilities. Accordingly, we disclose matters below for which a material loss is reasonably possible.
On August 25, 2016, Kforce Flexible Solutions LLC (along with co-defendant BMO Harris Bank) was served with a complaint brought in the Northern District of Illinois, U.S. District Court, Eastern District of Illinois. Shepard v. BMO Harris Bank N.A. et al., Case No.: 1:16-cv-08288. The plaintiff purports to bring claims on her own behalf and on behalf of putative class of telephone-dedicated workers for alleged violations of the Fair Labor Standards Act, the Illinois Minimum Wage Law, and the Illinois Wage Payment and Collection Act based upon the defendants’ purported failure to pay her and other class members all earned regular and overtime pay for all time worked. More specifically, the plaintiff alleges that class employees were required to perform unpaid work before and after the start and end times of their shifts. She seeks unpaid back regular and overtime wages, liquidated damages, statutory penalties, and attorney fees and costs. We are vigorously defending each of the plaintiff’s claims. At this stage in the litigation it is not feasible to predict the outcome of this matter or reasonably estimate a range of loss, should a loss occur, from this proceeding; however, based on our current knowledge, we believe that the final outcome of this matter is unlikely to have a material adverse effect on our business, consolidated financial position, results of operations, or cash flows.

EXECUTIVE SUMMARY
The following is an executive summary of what Kforce believes are 2016 highlights for 2018, which should be considered in the context of the additional discussions herein and in conjunction with the consolidated financial statements and notes thereto.
Net service revenues remained stable at $1.32Revenue increased 4.4% to $1.42 billion in 20162018 from $1.36 billion in 2017. Revenue increased 9.1% and 2015. Net service revenues decreased 1.4%9.7% for Tech and increased 3.6%GS, respectively, and 1.3%decreased 9.3% for FA and GS, respectively.FA.

Flex gross profit margin decreased 3040 basis points to 28.2%26.8% in 20162018 from 28.5%27.2% in 2015.2017. Flex gross profit margin decreasedincreased 10 basis points for Tech, 30 basis points for FA and 170decreased 10 basis points and 430 basis points for GS. These margin decreases were primarilyTech and GS, respectively. Our GS business is operating in a result of higher benefit costscost competitive environment and, as such, has experienced reduced profitability in each of our segments, lower margins on some of GS recompete wins and spread compression in Tech Flex due to an increase in revenue concentration within our large client portfolio where certain of these clients have, in many cases, narrowed the number of vendor partners that they are looking to do business with and are leveraging volume-based rebates in exchange for this increased concentration of business.its more recently awarded contracts.

The 90120 basis point increasedecrease was primarily driven by approximately $6.0 million, or 50 basis points, in severance costs that were recorded during 2016 associated with realignment activities focused on further streamlining our organization and $2.2 million, or 20 basis points, in costs associated with our sales transformation activities. In addition, we have made targeted investments in information technology as well as our revenue-generating talent during 2016, which has negatively impacted SG&Aincreased leverage as a percentageresult of revenue.enhancements to our performance-based compensation plans; improved associate productivity; reduced costs as a result of previous realignment activities; and a continued focus on expense discipline.
Net income for the year ended December 31, 2016 decreased 23.5%2018 increased 74.2% to $32.8$58.0 million from $42.8$33.3 million in 2015 primarily driven by the aforementioned $6.0 million in severance costs ($3.5 million after-tax), $2.2 million in costs associated with the investment in refining our sales methodology, messaging2017 and process ($1.2 million after-tax), and reduction in our gross profit of $5.6 million ($3.3 million after-tax) as well as certain tax adjustments of $1.7 million during 2016.
Diluteddiluted earnings per share for the year ended December 31, 2016 decreased2018 increased to $1.25$2.30 from $1.52$1.30 per share in 20152017, primarily driven by the aforementioned factors noted above as well as the reduction in our effective tax rate due to the net income description above.enactment of the TCJA.
During 2016,2018, Kforce repurchased 2.3 million553 thousand shares of common stock on the open market at a total cost of approximately $44.0$15.7 million. On October 26, 2018, the Board approved an increase in our stock repurchase authorization bringing the then available authorization to $100.0 million.
In the second half of 2018, the Board approved a 50% increase to the quarterly dividend, bringing it to $0.18 per share, up from $0.12 per share in the first half of 2018. The Firm declared and paid dividends totaling $0.48$0.60 per share during the year ended December 31, 2016,2018, resulting in a total cash payout of $12.4$14.9 million.

Cash provided by operating activities was $87.7 million during the year ended December 31, 2018 compared to $29.3 million for 2017 primarily driven by the returndue to increasing levels of capital toprofitability and improved collections of our shareholders in the form of dividends and common stock repurchases, which aggregated $56.4 million, but was also impacted by lower than anticipated operating cash flows in the fourth quarter as a result of the transition of certain back office processes from Manila to Tampa.accounts receivable.




RESULTS OF OPERATIONS
Based upon previous economic cycles experienced by Kforce,
In 2018, we believe that times of sustained economic recovery generally stimulate demand for additional U.S. workers and, conversely, an economic slowdown results in a contraction in demand for additional U.S. workers. From an economic standpoint, temporary employment figures and trends are important indicators of staffing demand, which continued to be positive during 2016, based on data published by the Bureau of Labor Statistics (“BLS”) and SIA. The penetration rate (the percentage of temporary staffing to total employment) in December 2016 was at 2.04%, a slight decline from the December 2015 high of 2.06%. While the health of the macro-employment picture was uncertain at times during 2016, it generally continuously improved, with the unemployment rate at 4.7% as of December 2016, and non-farm payroll expanding an average of approximately 180,000 jobs per month in 2016. Also, the college-level unemployment rate, which we believe serves as a proxy for professional employment and therefore aligns with the candidate and consultant population that Kforce serves, was at 2.5% in December 2016. Further, we believe that the unemployment rate in the specialties we serve, especially in certain technology skill sets, is lower than the published averages, which we believe speaks to the demand environment in which we are operating. Management believes that the tepid growth in the overall U.S. economy seen through much of 2016, the recent change in administration, and the increasing costs and government regulation of employment may be driving a secular shift to an increased use of temporary staff as a percentage of total workforce as employers may be reluctant to increase permanent hiring. If the penetration rate of temporary staffing experiences growth in the coming months and years, we believe our Flex revenues may grow even in a relatively modest growth macro-economic environment. Kforce remains optimistic about the growth prospects of the temporary staffing industry, the penetration rate, and in particular, our revenue portfolio; however, the economic environment includes considerable uncertainty and volatility and therefore no reliable predictions can be made about the general economy, the staffing industry as a whole, or specialty staffing in particular.
We continued to evolve and make progress on our strategic initiatives including: (1) enhancing our sales methodology and training
Implementing new and upgrading existing technologies that we believe will allow us to more effectively and efficiently serve our clients, consultants and candidates and improve the scalability of our organization. We completed the deployment of a new time and expense application for our consultants and clients as well as a new expense application for our associates. In addition, we continue to make enhancements to our business and data intelligence capabilities as well as our customer relationship management system. We expect these initiatives to benefit us in 2019 and beyond.
Improving our alignment of revenue-generating talent to the markets, products, industries and clients that present the greatest opportunity for profitable revenue growth.
Executing a Kforce brand refresh to reinforce our core values with a consistent message and identity.

We believe that the proper alignment and balance of our combined revenue-generating talent and revenue-enabling talent are keys to our future growth and profitability. We also believe that our portfolio of service offerings, which are almost exclusively in the U.S. and are focused in Tech and FA (which we anticipate to be areas of expected growth), are a key contributor to our long-term financial stability.

Flex Revenues.Revenue. The primarykey drivers of Flex revenuesrevenue are the number of consultantconsultants on assignment and billable hours, worked, the consultant bill rate per hour and, to a limited extent, the amount of billable expenses incurred by Kforce.
Flex revenuesrevenue for our largest segment, Tech, decreased 1.2%increased 9.4% during the year ended December 31, 20162018 as compared to 20152017 and increased 6.1%2.8% in 20152017 from 2014. Our year-over-year decrease in 2016 was due to a decline experienced in connection with several large clients after certain significant organizational changes occurred within a number of these clients in mid-2015 causing them to decrease their spending with the Firm (we had experienced revenue growth with these large clients in the first half of 2015). Despite this overall decrease, we experienced a reacceleration of year-over-year growth beginning in Q4 2016 within our overall Tech Flex business on a billing day basis as well as our Top 25 client portfolio, which suggests that the impact related to the shift in spend with certain large clients was temporary in nature.2016. We believe that broad-basedthe secular drivers to the demand inof technology staffing such as cloud-computing, data analytics, mobility, e-commerce, machine learning and cybersecurity will continue asspend remain intact with many companies are becoming increasingly dependent uponon the efficiencies provided by technology investmentsand the need for innovation to support business strategies and sustain relevancy in today’s rapidly changing marketplace. We believeOur belief in the strength in the demand environment within Tech Flex has not changed; thus, we are well positionedexpected continued growth in 2019 in this space. We expect Tech Flex revenues to grow year-over-year in 2017 due to the market strength, the opportunities we see with our clients and the investments in revenue-generating resources that we intend to allocate to growing priority client accounts.segment.
Our FA segment experienced an increasea decrease in Flex revenuesrevenue of 4.4%9.9% during the year ended December 31, 20162018 as compared to 20152017 and increased 18.0%3.6% in 20152017 from 2014. Due2016. The year-over-year decrease in 2018 from 2017 was primarily due to the high year-over-year growthreduced volume of lower bill rate inassignments as we begin to shift our focus towards higher skillset opportunities. In 2019, we expect FA Flex during 2015 we expected our 2016 year-over-year growth raterevenue to slow against this challenging comparison. We have continued to diversify our FA service offerings outside of what may be viewed as more traditional finance and accounting roles. The opportunities we have seen include larger volume projects in centralized functions such as benefits and other service and administrative functions. The Firm believes the FA segment will continue to achieve year-over-year growth in 2017.remain stable or slightly decrease year-over-year.

Our GS segment experienced an increase in net service revenuesFlex revenue of 1.3%6.5% during the year ended December 31, 20162018 as compared to 20152017 and decreased 0.7%increased 11.9% in 20152017 from 2014.2016. The 2016 year-over-year growthincrease in 2018 from 2017 was drivenpowered by high growth in servicethe first half of 2018, primarily a result of two new prime contract wins secured in the third quarter of 2017. Flex revenue for GS was lower than our expectations in the second half of 2018 due to anticipated new business awards not materializing as quickly as anticipated and billable headcount attrition on lower margin contracts. In October 2018, GS was awarded a subcontract having an estimated contract value of $150 million to $200 million. In November 2018, the award to the prime contractor was protested by two unsuccessful bidders. On February 21, 2019, we received notification that the protest was sustained and, as such, are working with the prime contractor to determine appropriate next steps. We expect revenues as well as strength in our product-based business. While the business continuesGS segment to operategrow in 2019 on a challenging and evolving procurement and contracting environment, the Firm believesyear-over-year basis.

These key drivers were impacted by the sale of Global’s assets, which occurred in the third quarter of 2017. During 2017, Global contributed approximately 4% of the total hours billed but only 1% of the revenue for Tech Flex. The volume previously contributed by Global has been replaced by organic growth in the remainder of our portfolio at significantly higher bill rates.

Total gross profit percentage decreased 50 basis points for the year ended December 31, 2018 as compared to 2017.
The 30 basis point decrease for Tech was due to a lower mix of Direct Hire revenue and a slight decline in Flex gross profit percentage.
The 60 basis point increase for FA was due to a higher mix of Direct Hire revenue and a slight increase in Flex gross profit percentage.
The 300 basis point decrease for GS was due to a large decrease in Flex gross profit, offset by a higher mix of Product revenue to Flex revenue.

The 40 basis point decrease in Flex gross profit percentage of 30 basis points in 2016 from 2015for the year ended December 31, 2018 as compared to 2017 was due primarily to an increase in benefit costs in each of our segments. Additionally, ourdriven by the decrease for GS. Tech and FA remained fairly stable year-over-year. GS segment realized lower margins on some of its recompete wins and a lower mix of higher margin business. Furthermore, during 2016 we experienced an increase in the revenue concentration within our large client portfolio in Tech Flex, which resulted in a reduction in the Flex gross profit percentage,margin decreased 430 basis points primarily due to compression in bill and spread compression withinpay spreads as well as higher benefit costs. GS business is operating in a cost competitive environment and, as such, has experienced reduced profitability in certain of these clients that have, in many cases, narrowed the number of vendor partners that they are looking to do business with and are leveraging volume-based rebates in exchange for this increased concentration of business. A continued focus for Kforce is optimizing the spread between bill rates and pay rates by providing our associates with tools, economic knowledge and defined programs to drive improvement in the effectiveness of our pricing strategy around the staffing services we provide and the clients that we serve.

Our effective tax rate for 2018 was positively impacted by the TCJA. For the year ended December 31, 2017, our effective tax rate was 48.1%, which was unfavorably impacted by the revaluation of our net deferred tax assets as a result of the TCJA. For the year ended December 31, 2016, our effective tax rate was 41.4%. Kforce’s effective rate during 2016, which was negativelyunfavorably impacted by certain one-time non-cash adjustments. For the year ended December 31, 2015, our effective rate was 40.3%. The 2015 effective rate was unfavorably impacted by a change in the overall mix of income in the various state jurisdictions and the increase in particular uncertain tax positions. For the year ended December 31, 2014, income tax expense as a percentage of income from continuing operations before income taxes was 38.7%.
Income from Discontinued Operations, Net of Income Taxes. Discontinued operations for the year ended December 31, 2014 include the consolidated income and expenses for HIM. During the three months ended September 30, 2014, Kforce completed the sale of HIM resulting in a pre-tax gain of $94.3 million. Included in the determination of the pre-tax gain is approximately $4.9 million of goodwill for HIM and transaction expenses totaling approximately $11.0 million, which primarily included legal fees, stock-based compensation related to acceleration of restricted stock due to change in control provisions, commissions and transaction bonuses. Income tax expense as a percentage of income from discontinued operations, before income taxes, for the year ended December 31, 2014 was 40.6%.
Non-GAAP Financial Measures
Adjusted EBITDA. “Adjusted EBITDA”, a non-GAAP financial measure, which is defined by Kforce as net income before income from discontinued operations, net of income taxes, depreciation and amortization, stock-based compensation expense, interest expense, net and income tax expense, and is based on the definition in our credit facility and is a key metric in our covenant calculations, as described in Note 8 - “Credit Facility” in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report. Adjusted EBITDA should not be considered a measure of financial performance under GAAP. Items excluded from Adjusted EBITDA are significant components in understanding and assessing our past and future financial performance, and this presentation should not be construed as an inference by us that our future results will be unaffected by those items excluded from Adjusted EBITDA. Adjusted EBITDA is a key measure used by management to assess our operations including our ability to generate cash flows and our ability to repay our debt obligations and management believes it provides a good metric of our core profitability in comparing our performance to our competitors. Consequently, management believes it is useful information to investors. The measure should not be considered in isolation or as an alternative to net income, cash flows or other financial statement information presented in the consolidated financial statements as indicators of financial performance or liquidity. The measure is not determined in accordance with GAAP and is thus susceptible to varying calculations. Also, Adjusted EBITDA, as presented, may not be comparable to similarly titled measures of other companies.
In addition, although we excluded amortization of stock-based compensation expense (which we expect to continue to incur in the future) because it is a non-cash expense, the associated stock issued may result in an increase in our outstanding shares of stock, which may result in the dilution of our stockholder ownership interest. We suggest that you evaluate these items and the potential risks of excluding such items when analyzing our financial position.

Free Cash Flow. “Free Cash Flow”, a non-GAAP financial measure, is defined by Kforce as net cash provided by (used in) operating activities determined in accordance with GAAP, less capital expenditures. Management believes this provides an additional way of viewing our liquidity that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our cash flows and is useful information to investors as it provides a measure of the amount of cash generated from the business that can be used for strategic opportunities including investing in our business, making acquisitions, repurchasing common stock or paying dividends. Free cash flow has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures.
Therefore, we believe it is important to view free cash flow as a complement to our Consolidated Statements of Cash Flows.

Adjusted EBITDA. “Adjusted EBITDA”, a non-GAAP financial measure, is defined by Kforce as net income before depreciation and amortization, stock-based compensation expense, interest expense, net and income tax expense. Adjusted EBITDA should not be considered a measure of financial performance under GAAP. Items excluded from Adjusted EBITDA are significant components in understanding and assessing our past and future financial performance, and this presentation should not be construed as an inference by us that our future results will be unaffected by those items excluded from Adjusted EBITDA. Adjusted EBITDA is a key measure used by management to assess our operations including our ability to generate cash flows and our ability to repay our debt obligations. Management believes it is useful information to investors as it provides a good metric of our core profitability in comparing our performance to our competitors, as well as our performance over different time periods. The measure should not be considered in isolation or as an alternative to net income, cash flows or other financial statement information presented in the consolidated financial statements as indicators of financial performance or liquidity. The measure is not determined in accordance with GAAP and is susceptible to varying calculations, and as presented, may not be comparable to similarly titled measures of other companies.
In addition, although we excluded amortization of stock-based compensation expense because it is a non-cash expense, we expect to continue to incur stock-based compensation in the future and the associated stock issued may result in an increase in our outstanding shares of stock, which may result in the dilution of our shareholder ownership interest. We suggest that you evaluate these items and the potential risks of excluding such items when analyzing our financial position.

LIQUIDITY AND CAPITAL RESOURCES
To meet our capital and liquidity requirements, we primarily rely on operating cash flow, as well as borrowings under our existing credit facility.Credit Facility. At December 31, 2016,2018, Kforce had $140.2$158.1 million in working capital compared to $126.8$161.7 million at December 31, 2015.2017.
The accompanying Consolidated Statements of Cash Flows for each of the years ended December 31, 2016, 2015 and 2014 in Item 8. Financial Statements and Supplementary Data provide a more detailed description of our cash flows. Currently, Kforce is
We are principally focused on achieving thean appropriate balance in the followingof cash flow across several areas of cash flow: (1) achievingopportunity such as: generating positive cash flow from operating activities; (2) returning capital to our shareholders through our quarterly dividends and common stock repurchase program; (3) maintaining an appropriate outstanding balance onleverage under our credit facility; (4)Credit Facility; investing in our infrastructure to allow sustainable growth via capital expenditures; and (5) havingmaintaining sufficient liquidity to complete acquisitions or other strategic investments.

Operating Activities
Our largest source of operating cash flows is the collection of trade receivables and our largest use of operating cash flows is the payment of our consultant and associate compensation. When comparing cash flows from operating activities, the increase in cash provided by operating activities during the year ended December 31, 2018, as compared to 2017 was primarily due to increased levels of profitability and improved collections of our accounts receivable as well as $11.0 million related to the decreased effective tax rate as a result of the enactment of the TCJA and the receipt of a $6.8 million income tax refund. The decrease in cash provided by operating activities during the year ended December 31, 2017 as compared to 2016 was primarily due to an increase in accounts receivable, which was primarily driven by the revenue growth in our business, the timing of collections and continued pressure from certain larger clients for extended payment terms.
Investing Activities
Capital expenditures for the possibilityyears ended December 31, 2018, 2017 and 2016, which exclude equipment acquired under capital leases, were $5.2 million, $5.8 million and $12.4 million, respectively. We continually review our portfolio of completingbusinesses and their operations in comparison to our internal strategic and performance objectives. As part of this review, we may acquire other businesses and further invest in, fully divest and/or sell parts of our current businesses.
Financing Activities
The increase in cash used for financing activities in 2018 compared to 2017 was primarily driven by a reduction in our Credit Facility balance as well as an acquisition orincrease in cash used for an unexpected necessary expense.common stock repurchases and dividends. 
The decrease in cash used for financing activities in 2017 as compared to 2016 was primarily due to a reduction in our Credit Facility balance, offset by fewer common stock repurchases in 2017 than 2016.

During the years ended December 31, 2018, 2017 and 2016, Kforce declared and paid dividends of $14.9 million ($0.60 per share), $12.1 million ($0.48 per share), and $12.4 million ($0.48 per share), respectively. During the year ended December 31, 2018, the Board approved a 50% increase to our quarterly dividend, bringing the payout to $0.18 per share in the second half of 2018, as compared to a quarterly dividend of $0.12 per share for the first half of 2018. During the years ended December 31, 2017 and 2016, Kforce declared and paid a quarterly dividend of $0.12 per share for all shares outstanding. The declaration, payment and amount of future dividends are discretionary and will be subject to determination by Kforce’s Board each quarter following its review of, among other things, the Firm’s current and expected financial performance as well as the ability to pay dividends under applicable law.
We believe that existing cash and cash equivalents, cash flow from operations and available borrowings under our credit facilityCredit Facility will be adequate to meet the capital expenditure and working capital requirements of our operations for at least the next 12 months. However, a material deterioration in the economic environment or market conditions, among other things, could negatively impact operating results and liquidity, as well as the ability of our lenders to fund borrowings.
Actual results could also differ materially from those indicated as a result of a number of factors, including the use of currently available resources for possiblepotential acquisitions and possible additional stock repurchases.

Credit Facility
On May 25, 2017, the Firm entered into a credit agreement with Wells Fargo Bank, National Association, as administrative agent, Wells Fargo Securities, LLC, as lead arranger and bookrunner, Bank of America, N.A., as syndication agent, Regions Bank and BMO Harris Bank, N.A., as co-documentation agents, and the lenders referred to therein (the “Credit Facility”). Under the Credit Facility, the Firm has a maximum borrowing capacity of $300.0 million, which may, subject to certain conditions and the participation of the lenders, be increased up to an aggregate additional amount of $150.0 million (the “Commitment”), which is available to the Firm in the form of revolving credit loans, swingline loans and letters of credit. Letters of credit and swingline loans under the Credit Facility are subject to sublimits of $10.0 million. The following table presentsmaturity date of the Credit Facility is May 25, 2022. Borrowings under the Credit Facility are secured by substantially all of the tangible and intangible assets of the Firm, excluding the Firm’s corporate headquarters and certain other designated executed collateral. As of December 31, 2018, $71.8 million was outstanding and $225.0 million was available, subject to the covenants described below and as of December 31, 2017, $116.5 million was outstanding.
The Firm is subject to certain affirmative and negative covenants including (but not limited to), the maintenance of a summaryfixed charge coverage ratio of no less than 1.25 to 1.00 and the maintenance of a total leverage ratio of no greater than 3.25 to 1.00. The numerator in the fixed charge coverage ratio is defined pursuant to the Credit Facility as earnings before interest expense, income taxes, depreciation and amortization, stock-based compensation expense and other permitted items pursuant to our Credit Facility (disclosed as “Consolidated EBITDA”), less cash paid for capital expenditures, income taxes and dividends. The denominator is defined as Kforce’s fixed charges such as interest expense and principal payments paid or payable on outstanding debt other than borrowings under the Credit Facility. The total leverage ratio is defined pursuant to the Credit Facility as total indebtedness divided by Consolidated EBITDA. Our ability to make distributions or repurchases of equity securities could be limited if an event of default has occurred. Furthermore, our ability to repurchase equity securities could be limited if: (a) the total leverage ratio is greater than 2.75 to 1.00; and (b) the Firm’s availability, inclusive of unrestricted cash, is less than $25.0 million. At December 31, 2018, Kforce was not limited in making distributions and executing repurchases of our net cash flows from operating, investing and financing activities (in thousands):

Discontinued Operations
As was previously discussed, Kforce divested of HIM during 2014. The accompanying Consolidated Statements of Cash Flows have been presented on a combined basis (continuing operations and discontinued operations) for the year ended December 31, 2014. Cash flows provided by discontinued operations for all prior periods were provided by operating activities and were not materialequity securities. Refer to the capital resources of Kforce. In addition, the absence of cash flows from discontinued operations is not expected to have a significant effect on the future liquidity, financial position, or capital resources of Kforce.
Operating Activities
Our largest source of operating cash flows is the collection of trade receivables and our largest use of operating cash flows is the payment of our employee and consultant populations’ compensation, which includes base salary, commissions and bonuses. When comparing cash flows from operating activities, the decrease in cash provided by operating activities during the year ended December 31, 2016 as compared to 2015 is primarily a result of lower earnings due to large cash usages related to severance costs associated with realignment activities focused on further streamlining our organization, costs associated with the investment in refining our sales methodology, and investments in information technology and our revenue-generating talent, as well as transitioning certain back office functions from our Manila location to our Tampa headquarters in the fourth quarter, which impacted the timing in collections of accounts receivable. The increase in cash provided by operating activities during the year ended December 31, 2015 as compared to 2014 is primarily a result of improved timing of collections of accounts receivable as well as growth in our profitability.
Investing Activities
Capital expenditures for the years ended December 31, 2016, 2015 and 2014, which exclude equipment acquired under capital leases, were $12.4 million, $8.3 million and $6.0 million, respectively. Proceeds from the divestiture of HIM were $117.9 million during the year ended December 31, 2014.
We expect to continue selectively investing in our infrastructure in order to support the expected future growth in our business. We believe that we have sufficient cash and availability under the credit facility to make any expected necessary capital expenditures in the foreseeable future. In addition, we continually review our portfolio of businesses and their operations in comparison to our internal strategic and performance objectives. As part of this review, we may acquire other businesses and further invest in, fully divest and/or sell parts of our current businesses.

Under the credit facility, Kforce is subject to certain affirmative and negative covenants including, but not limited to, a fixed charge coverage ratio, which is only applicable in the event that the Firm’s availability under the credit facility falls below the greater of (a) 10% of the aggregate amount of the commitment of all of the lenders under the credit facility and (b) $11 million. The numerator in the fixed charge coverage ratio is defined pursuant to the credit facility as earnings before interest expense, income taxes, depreciation and amortization, including the amortization of stock-based compensation expense (disclosed as “Adjusted EBITDA”), less cash paid for capital expenditures. The denominator is defined as Kforce’s fixed charges such as interest expense, principal payments paid or payable on outstanding debt other than borrowings under the credit facility, income taxes payable, and certain other payments. This financial covenant, if applicable, requires that the numerator be equal to or greater than the denominator.
Our ability to repurchase equity securities could be limited if the Firm’s availability is less than the greater of (a) 15.0% of the aggregate amount of the commitment of all lenders under the credit facility or (b) $15.0 million. Also, our ability to make distributions could be limited if the Firm’s availability is less than the greater of (a) 12.5% of the aggregate amount of the commitment of all lenders under the credit facility and (b) $20.6 million.

Off-Balance Sheet Arrangements
Kforce provides letters of credit to certain vendors in lieu of cash deposits. At December 31, 2016,2018, Kforce had letters of credit outstanding for workers’ compensation and other insurance coverage totaling $3.1$2.8 million, and for facility lease deposits totaling $0.4$0.3 million.

CRITICAL ACCOUNTING ESTIMATES
Our significant accounting policies are discussed in Note 1 – “Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report. Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”).GAAP. In connection with the preparation of our consolidated financial statements, we are required to make assumptions and estimates about future events, and apply judgments that affect the reported amount of assets, liabilities, revenues, expenses and the related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our consolidated financial statements are prepared. On a regular basis, management reviews the accounting policies, estimates, assumptions and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material.
Our significant accounting policies are discussed in Note 1 – “Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report. Management believes that the following accounting estimates are the most critical to aid in fully understanding and evaluating our reported financial results, and they require management’s most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain.

Allowance for Doubtful Accounts, Fallouts and Other Accounts Receivable Reserves
See Note 1 – “Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report, for a complete discussion of our policies related to determining our allowance for doubtful accounts, fallouts and other accounts receivable reserves.
Kforce performs an ongoing analysis of factors including recent write-off and delinquency trends, a specific analysis of significant receivable balances that are past due, the concentration of accounts receivable among clients and higher-risk sectors, and the current state of the U.S. economy, in establishing its allowance for doubtful accounts.
Kforce estimates its allowance for Direct Hire fallouts based on our historical experience with the actual occurrence of fallouts.
Kforce estimates its reserve for future revenue adjustments (e.g. bill rate adjustments, time card adjustments, early pay discounts) based on our historical experience.
We have not made any material changes in the accounting methodology used to establish our allowance for doubtful accounts, fallouts and other accounts receivable reserves. As of December 31, 2016 and 2015, these allowances were 1.0% and 1.1% as a percentage of gross accounts receivable, respectively.
We do not believe there is a reasonable likelihood that there will be a material change in the future estimates or assumptions we use to calculate our allowance for doubtful accounts, fallouts and other accounts receivable reserves. However, if our estimates regarding estimated accounts receivable losses are inaccurate, we may be exposed to losses or gains that could be material. A 10% change in accounts receivable reserved at December 31, 2016, would have impacted our net income for 2016 by approximately $0.1 million.
We have not made any material changes in our accounting methodologies used from the prior years.

Goodwill Impairment
We evaluate goodwill for impairment annually or more frequently whenever events or circumstances indicate that the fair value of a reporting unit is below its carrying value. We monitor the existence of potential impairment indicators throughout the year. See Note 5 – “Goodwill and Other Intangible Assets in the Notes to Consolidated Financial Statements, included in Item 8.

Accounting for Income Taxes
Our consolidated effective income tax rate is influenced by tax planning opportunities available to us in the various jurisdictions in which we conduct business. Significant judgment is required in determining our effective tax rate and in evaluating our tax positions, including those that may be uncertain.
We are also required to exercise judgment with respect to the realization of our net deferred tax assets. Management evaluates all positive and negative evidence and exercises judgment regarding past and future events to determine if it is more likely than not that all or some portion of the deferred tax assets may not be realized. If appropriate, a valuation allowance is recorded against deferred tax assets to offset future tax benefits that may not be realized.
Refer to Note 5 – “Income Taxes” in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report for a complete discussion of the components of Kforce’s income tax expense, as well as the temporary differences that exist as of December 31, 2018.
Self-Insured Liabilities
We are self-insured for certain losses related to health insurance and workers’ compensation claims that are below insurable limits. However, we obtain third-party insurance coverage to limit our exposure to claims in excess of insurable limits. When estimating our self-insured liabilities, we consider a number of factors, including historical claims experience, plan structure, internal claims management activities, demographic factors and severity factors. Periodically, management reviews its assumptions to determine the adequacy of our self-insured liabilities.
Our self-insured liabilities contain uncertainties because management is required to make assumptions and to apply judgment to estimate the ultimate total cost to settle reported claims and claims incurred but not reported (“IBNR”) as of the balance sheet date.
Defined Benefit Pension Plan
The SERP is a defined benefit pension plan that benefits certain named executive officers. The SERP was not funded as of December 31, 2018 or 2017. When estimating the obligation for our pension benefit plan, management is required to make certain assumptions and to apply judgment with respect to determining an appropriate discount rate, bonus percentage assumptions and expected effect of future compensation increases for the participants in the plan.
Refer to Note 9 – “Employee Benefit Plans” in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report for a complete discussion of the terms of this plan.
Goodwill Impairment
Goodwill is tested at the reporting unit level which is generally an operating segment, or one level below the operating segment level, where a business operates and for which discrete financial information is available and reviewed by segment management. We evaluate goodwill for impairment annually or more frequently whenever events or circumstances indicate that the fair value of a reporting unit is below its carrying value. We monitor the existence of potential impairment indicators throughout the year. It is our policy to conduct impairment testing based on our current business strategy in light of present industry and economic conditions, as well as future expectations.
When performing a quantitative assessment, we determine the fair value of our reporting units using widely accepted valuation techniques, including the discounted cash flow, guideline transaction and guideline company methods. These types of analyses contain uncertainties because they require management to make significant assumptions and judgments including: (1) an appropriate rate to discount the expected future cash flows; (2) the inherent risk in achieving forecasted operating results; (3) long-term growth rates; (4) expectations for future economic cycles; (5) market comparable companies and appropriate adjustments thereto; and (6) market multiples. When performing a qualitative assessment, we assess qualitative factors to determine whether the existence of events or circumstances indicated that it was more likely than not that the fair value of the reporting unit was less than its carrying amount.
For all of our segments (Tech, FA and GS) reporting units, Kforce assessed the qualitative factors of each reporting unit to determine if it was more likely than not that the fair value of the reporting unit was less than its carrying amount. Based on the qualitative assessments, management determined that it was not more likely than not that the fair values of the reporting units were less than the carrying values. A deterioration in any of the assumptions could result in an impairment charge in the future.
See Note 6 – “Goodwill and Other Intangible Assets in the Notes to Consolidated Financial Statements, included in Item 8. Financial Statements and Supplementary Data of this report for a complete discussion of the valuation methodologies employed.

The carrying value of goodwill as of December 31, 2016 by reporting unit was approximately $17.0 million, $8.0 million and $20.9 million for our Tech, FA and GS reporting units, respectively.
We determine the fair value of our reporting units using widely accepted valuation techniques, including the discounted cash flow, guideline transaction method and guideline company method. These types of analyses contain uncertainties because they require management to make significant assumptions and judgments including: (1) an appropriate rate to discount the expected future cash flows; (2) the inherent risk in achieving forecasted operating results; (3) long-term growth rates; (4) expectations for future economic cycles; (5) market comparable companies and appropriate adjustments thereto; and (6) market multiples.

It is our policy to conduct impairment testing based on our current business strategy in light of present industry and economic conditions, as well as future expectations.
For our Tech and FA reporting units, Kforce assessed the qualitative factors of each reporting unit to determine if it was more likely than not that the fair value of the reporting unit was less than its carrying amount. Based upon the qualitative assessments, it was determined that it was not more likely than not that the fair values of the reporting units were less than the carrying values.

For our GS reporting unit, however, a quantitative step one impairment assessment was performed as of December 31, 2016. We compared the carrying value of the GS reporting unit to its estimated fair value noting that the fair value exceeded carrying value by over 100%. As a result, no goodwill impairment charges were recognized during the year ended December 31, 2016.

Although the valuation of the business supported its carrying value in 2016, a deterioration in any of the assumptions could result in an additional impairment charge in the future.

Our liabilities for health insurance and workers’ compensation claims as of December 31, 2016 were $2.8 million and $1.3 million, respectively.
Our self-insured liabilities contain uncertainties because management is required to make assumptions and to apply judgment to estimate the ultimate total cost to settle reported claims and claims incurred but not reported (“IBNR”) as of the balance sheet date.
We have not made any material changes in the accounting methodologies used to establish our self-insured liabilities during 2016 and 2015.
We do not believe there is a reasonable likelihood that there will be a material change in the estimates or assumptions we use to calculate our self-insured liabilities. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to losses or gains that could be material.
A 10% change in our self-insured liabilities related to health insurance and workers’ compensation as of December 31, 2016 would have impacted our net income for 2016 by approximately $0.2 million.

KFORCE INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared in conformity with U.S. GAAP and the rules of the SEC.
Principles of Consolidation
The consolidated financial statements include the accounts of Kforce Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. References in this document to “the Registrant,” “Kforce,” “the Company,” “we,” “the Firm,” “management,” “our” or “us” refer to Kforce Inc. and its subsidiaries, except where the context indicates otherwise.
Use of Estimates
The preparation of consolidated financial statements in conformity with GAAP 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. The most important of these estimates and assumptions relate to the following: allowance for doubtful accounts, fallouts and other accounts receivable reserves; accounting for goodwill and identifiable intangible assets and any related impairment;accounts; income taxes; self-insured liabilities for workers’ compensation and health insurance; obligations for pension plans and accounting for income taxes.goodwill and any related impairment. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates.
Revenue Recognition
Kforce considers amountsAll of our revenue and trade receivables are generated from contracts with customers and substantially all of our revenues are derived from U.S. domestic operations. The following section describes the accounting policies that we believe have significant judgment, or changes in judgment, as a result of adopting Topic 606.
Revenue is recognized when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to be earned once evidenceentitled to in exchange for those goods or services. Revenue is recorded net of an arrangement has been obtained, delivery has occurred, fees are fixedsales or determinable,other transaction taxes collected from clients and collectability is reasonably assured. Kforce’s primary sourcesremitted to taxing authorities.
For substantially all of our revenue transactions, we have determined that gross reporting of revenues are Flexas a principal versus net as an agent is the appropriate accounting treatment because Kforce: (i) is primarily responsible for fulfilling the promise to provide the specified good or service to the customer, (ii) has discretion in selecting and Direct Hire.assigning the temporary workers to particular jobs and establishing the bill rate, and (iii) bears the risk and rewards of the transaction, including credit risk if the customer fails to pay for services performed.
Flex revenues areRevenue
Flex revenue is recognized over time as thetemporary staffing services are provided by Kforce’s consultants. Kforce records revenuesour consultants at the contractually established bill rates, net of credits, discounts, rebates and revenue-related reserves. Revenues include reimbursementsapplicable variable consideration. Reimbursements of travel and out-of-pocket expenses (“("billable expenses”expenses") withare also recorded within Flex revenue when incurred and the equivalent amountsamount of expense is recorded in directDirect costs in the Consolidated Statements of services.Operations and Comprehensive Income.
Certain temporary staffing services are provided under time-and-material and fixed-price arrangements. For time-and-materials contracts, we recognize revenue in the amount of consideration to which we have the right to invoice when it corresponds directly to the services transferred to the customer satisfied over time. For fixed-price contracts, which are most frequently utilized in our GS segment, revenue is recognized over time using the input method based on costs incurred as a proportion of estimated total costs. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Management uses significant judgments when estimating the total labor hours expected to complete the contract performance obligation.
Direct Hire revenues areRevenue
Direct Hire revenue is recognized by Kforceat the agreed upon rate at the point in time when employment candidates accept offersthe performance obligation is considered complete. Our policy requires the following criteria to be met in order for the performance obligation to be considered complete: (i) the candidate accepted the position; (ii) the candidate resigned from their current employer; and (iii) the agreed upon start date falls within the following month. Since the client has accepted the candidate and can direct the use of permanent employment and are scheduledobtains the significant risk and rewards of the placement, we consider this point as the transfer of control to commence employment within 30 days. Kforce records revenuesour client.
Product Revenue
Revenue for our product business, which accounts for approximately 1% of total revenue for each of the years ended December 31, 2018, 2017 and 2016, is recognized after the transfer of control to the customer, which typically occurs upon delivery.

Variable Consideration
Transaction prices for Flex revenue include variable consideration, such as customer rebates and discounts. Management evaluates the facts and circumstances of each contract to estimate the variable consideration using the most likely amount method which utilizes management’s expectation of the volume of services to be provided over the applicable period. Direct Hire revenue is recorded net of an estimated reserve fora fallout reserve. Direct Hire fallouts which is based on Kforce’s historical fallout experience. Fallouts occur when a candidate does not remain employed with the client through the respective contingency period which is typically(typically 90 days or less.less). Management uses the expected value method to estimate the fallout reserve based on a combination of past experience and current trends. Variable consideration reduces revenue, but may be constrained to the extent that it is probable a significant reversal will not occur. These balances are recorded in Accounts payable and other accrued liabilities in the Consolidated Balance Sheets.
Under Topic 605, the Direct Hire fallout reserve was recorded as a Trade receivables allowance and under Topic 606, it is recorded within Accounts payable and other accrued liabilities in the Consolidated Balance Sheets. As of December 31, 2018 and 2017, the Direct Hire fallout reserve was $0.6 million and $0.5 million, respectively.
Payment Terms
Our GS segment generates its revenues under contracts thatpayment terms and conditions vary by arrangement, although terms are in general, greater in durationtypically less than our other segments and which can often span several years, inclusive of renewal periods. Our GS segment does not generate any Direct Hire revenues. Our GS segment, which represents approximately 7% of total revenues, generates revenues under90 days. Generally, the following contract arrangements.
Revenues for time-and-materials contracts, which accounts for approximately 62% of this segment’s revenue, are recognized based on contractually established billing rates attiming between the time services are provided.
Revenues for fixed-price contracts are recognized on the basissatisfaction of the estimated percentage-of-completion. Approximately 22%performance obligation and the payment is not significant and we do not currently have any significant financing components.
Unsatisfied Performance Obligations
We do not disclose the value of this segment’s revenues are recognized under this method. Progress towards completionunsatisfied performance obligations for contracts if either the original expected length is typically measured based on costs incurred as a proportion of estimated total costsone year or other measures of progress when applicable. Profit in a given periodless or if revenue is reported at the expected profit margin to be achieved on the overall contract.
Revenues for the product-based business, which accounts for approximately 16% of this segment’s revenues, are recognized at the timeamount to which we have the right to invoice for services performed.
Contract Balances
We record accounts receivable when our right to consideration becomes unconditional. Other than our trade receivable balance, we do not have any material contract assets as of delivery.January 1, 2018 and December 31, 2018.
Kforce collects sales tax for various taxing authoritiesWe record a contract liability when we receive consideration from a customer prior to transferring goods or services to the customer or if we have an unconditional right and it is our policyservices have been performed. We recognize the contract liability as revenue after we have transferred control of the goods or services to record these amounts on a net basis; thus, sales tax amountsthe customer. Contract liabilities are recorded within Accounts payable and other accrued liabilities if expected to be recognized in less than one year and Other long-term liabilities, if over one year, in the Consolidated Balance Sheets. We do not included in net service revenues.have any material contract liabilities as of January 1, 2018 and December 31, 2018.

Direct CostsCost of Services
Direct costs of services are composed of all related costs of employment for its consultants, including payroll wages,compensation, payroll taxes, payroll-related insurance and certain fringe benefits as well asand subcontractor costs. Direct costs of services exclude depreciation and amortization expense (except for the product business), which is presented on a separate line in the accompanying Consolidated Statements of Operations and Comprehensive Income.
Associate and field management compensation, payroll taxes and fringe benefits are included in selling, general and administrative expenses (“SG&A”), along with other customary costs such as administrative and corporate costs.
Commissions
Our associates make placements and earn commissions as a percentage of revenues (forgross profit for Flex or Direct Hire revenues) or gross profit (for Flex revenues)revenues pursuant to a calendar-year-basis commission plan. The amount of associate commissions paid as a percentage of revenues or gross profit increases as volume increases. Kforce accrues commissions for revenues or gross profitCommissions are accrued at a percentagean amount equal to the percent of total expected commissions payable to total revenuesrevenue or gross profit for the year,commission-plan period, as applicable. We generally expense sales commissions and any other incremental costs of obtaining a contract as incurred because the amortization period is typically less than one year.
Stock-Based Compensation

First, tax positions are recognized if the weight of available evidence indicates thatwhen it is more likely than not that the position will be sustained upon examination, including resolutionresolutions of any related appeals or litigation processes, if any. Second, tax positions are measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement. Kforceprocesses.

Cash and Cash Equivalents
Kforce classifies allAll highly liquid investments with an original initial maturity dates of three months or less at the time of purchase are classified as cash equivalents. Cash and cash equivalents consist of cash on hand with banks, either in commercial accounts or overnight interest-bearing money market accounts and at times may exceed federally insured limits. Cash and cash equivalents are stated at cost, which approximates fair value due tobecause of the short durationshort-term nature of their maturities.these instruments.
Accounts ReceivableTrade Receivables and Accounts ReceivableRelated Reserves
Kforce records accounts receivable at the invoiced amount. Kforce establishes its reservesTrade receivables are recorded net of allowance for expected credit losses, fallouts, early payment discounts and revenue adjustments based on past experience and estimates of potential future activity. Specific to ourdoubtful accounts. The allowance for doubtful accounts which comprises a majority of our accounts receivable reserves, Kforce performs an ongoing analysis ofis determined based on factors including recent write-off and delinquency trends, a specific analysis of significant receivable balances that are past due, the concentration of accounts receivabletrade receivables among clients and higher-risk sectors, and the current state of the U.S. economy. Trade receivables are written off by Kforce after all reasonable collection efforts have been exhausted. AccountsTrade accounts receivable reserves as a percentage of gross accounts receivabletrade receivables was 1.0% and 1.1% as ofat December 31, 20162018 and December 31, 2015, respectively.

Fixed Assets
Fixed assets are carried at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The cost of leasehold improvements is amortized using the straight-line method over the shorterlesser of the estimated useful lives of the assets or the terms of the related leases, which generally range from three to five years.leases. Upon sale or disposition of our fixed assets, the cost and accumulated depreciation are removed and any resulting gain or loss, net of proceeds, is reflected within SG&A in the Consolidated Statements of Operations and Comprehensive Income.
Leases
Leases for our field offices, which are located throughout the U.S., range from three to five-yearseven-year terms, although a limited number of leases contain short-term renewal provisions that range from month-to-month to one year.
For leases that contain escalations of the minimum rent, we recognize the related rent expense on a straight-line basis over the lease term. We record any difference between the straight-line rent amounts and amounts payable under the leases as a deferred rent liability in Accounts payable and other accrued liabilities or Other long-term liabilities, as appropriate.appropriate, in the Consolidated Balance Sheets.
The Company records incentives provided by landlords for leasehold improvements in Accounts payable and other accrued liabilities or Other long-term liabilities, as appropriate, in the Consolidated Balance Sheets and records a corresponding reduction in rent expense on a straight-line basis over the lease term.

Goodwill and Other Intangible Assets
Goodwill
Management has determined that the reporting units for the goodwill analysis is consistent with our reporting segments. We evaluate goodwill for impairment either through a qualitative or quantitative approach annually, or more frequently if an event occurs or circumstances change that indicate the carrying value of a reporting unit may not be recoverable. In testing for goodwill impairment,If we may elect to utilizeperform a qualitativequantitative assessment to evaluate whether it is more likely than not that indicates the fair valuecarrying amount of a reporting unit is less thanexceeds its carrying amount. If our qualitative assessment indicates that the fair value may be impaired or if we elect not to utilize a qualitative assessment for the evaluation, we perform a two-step impairment test. Under the two-step analysis method, the recoverability of goodwill is measured at the reporting unit level, which Kforce has determined to be consistent with its reporting segments, by comparing the reporting unit’s carrying amount, including goodwill, to the fair market value, ofan impairment loss is recognized to reduce the reporting unit.carrying amount to its fair market value. Kforce determines the fair market value of itseach reporting unitsunit based on a weighting of the present value of projected future cash flows (the “income approach”) and the use of comparative market approaches under both the guideline company method and guideline transaction method (collectively, the “market approach”). Fair market value using the income approach is based on Kforce’s estimated future cash flows on a discounted basis. The market approach compares each of Kforce’s reporting unitsunit to other comparable companies based on valuation multiples derived from operational and transactional data to arrive at a fair value. Factors requiring significant judgment include, among others, the assumptions related to discount rates, forecasted operating results, long-term growth rates, the determination of comparable companies, and market multiples. Changes in economic orand operating conditions or changes in Kforce’s business strategies that occur after the annual impairment analysis and whichmay impact these assumptions mayand result in a future goodwill impairment charge, which could be material to Kforce’sour consolidated financial statements.
Other Intangible Assets
Identifiable intangible assets arising from certain of Kforce’s acquisitions include non-compete and employment agreements, contractual relationships, customerclient contracts, technology, and a trade name andGS’s Data Confidence trademark. Our trade names and trademarks, and derivatives thereof, andincluding GS’s Data Confidence trademark, are important to our business. Our primary trade namesbusiness and trademark are registered with the U.S. Patent and Trademark Office.
For definite-lived intangible assets, amortization is computed using the straight-line method over the period of expected benefit, which ranges from one to fifteen years. The impairment evaluation for indefinite-lived intangible assets which for Kforce consists of a trademark and trade name, is conducted on an annual basis or more frequently if events or changes in circumstances indicate that an asset may be impaired.
Impairment of Long-Lived Assets
Kforce reviews long-livedLong-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of long-lived assets is measured by a comparison of the carrying amount of the asset group to the future undiscounted net cash flows expected to be generated by those assets. If such assets are considered to be impaired, the impairment charge recognized is the amount by whichan analysis indicates the carrying amountsamount of thethese long-lived assets exceedexceeds the fair value, ofan impairment loss is recognized to reduce the assets,carrying amount to its fair market value, as determined based on the present value of projected future cash flows.

Capitalized Software
Kforce purchases, develops and implements software to enhance the performance of our technology infrastructure. Direct internal costs, such as payroll and payroll-related costs, and external costs incurred during the development stage are capitalized and classified as capitalized software. Capitalized software development costs and the associated accumulated amortization are classified as Other assets, net in the accompanying Consolidated Balance Sheets; amortizationSheets. Amortization is computed using the straight-line method over the estimated useful lives of the software, which range from one to seven years.
Workers’ Compensation
Kforce retains the economic burden for the first $250 thousand per occurrence in workers’ compensation claims except: (1) in states that require participation in state-operated insurance funds and (2) for Kforce Government Solutions, Inc. which is fully insured for workers’ compensation claims. Workers’ compensation includes ongoing health care and indemnity coverage for claims and may be paid over numerous years following the date of injury. Workers’ compensation expense includes insurance premiums paid, claims administration fees charged by Kforce’s workers’ compensation administrator, premiums paid to state-operated insurance funds and an estimate for Kforce’s liability for IBNR claims and for the ongoing development of existing claims.
KforceManagement estimates its workers’ compensation liability based upon historical claims experience, actuarially determined loss development factors, and qualitative considerations such as claims management activities.
Health Insurance
Except for certain fully insured health insurance lines of coverage, Kforce retains the risk of loss for each health insurance plan participant up to $350 thousand in claims annually. Additionally, for all claim amounts exceeding $350 thousand, Kforce retains the risk of loss up to an aggregate annual loss of those claims of $450$700 thousand. For its partially self-insured lines of coverage, health insurance costs are accrued using estimates to approximate the liability for reported claims and IBNR claims, which are primarily based upon an evaluation of historical claims experience, actuarially-determined completion factors and a qualitative review of our health insurance exposure including the extent of outstanding claims and expected changes in health insurance costs.
Accounting for
Defined Benefit Pension BenefitsPlan
Kforce recognizes theThe unfunded status of its defined benefit pension plansplan is recorded as a liability in its Consolidated Balance Sheets. Because our plans areplan is unfunded as of December 31, 2016,2018, actuarial gains and losses may arise as a result of the actuarial experience of the plans,plan, as well as changes in actuarial assumptions in measuring the associated obligation as of year-end, or an interim date if any re-measurement is necessary. The net after-tax impact of unrecognized actuarial gains and losses related to our defined benefit pensions planspension plan is recorded in accumulatedAccumulated other comprehensive income (loss) in our consolidated financial statements.
Amortization of a net unrecognized gain or loss in accumulated other comprehensive income (loss) is included as a component of net periodic benefit cost if, as of the beginning of the year, that net gain or loss exceeds 10% of the projected benefit obligation. If amortization is required, the minimum amortization shall be that excess divided by the average remaining service period of active plan participants. The interest cost component of the net periodic benefit cost is included in Other expense, net in the Consolidated Statements of Operations and Comprehensive Income.
Earnings per Share
Basic earnings per share is computed as earningsnet income divided by the weighted average number of common shares outstanding (“WASO”) during the period. WASO excludes unvested shares of restricted stock. Diluted earnings per common share is computed by dividing the earnings attributable to common shareholdersnet income by diluted WASO. Diluted WASO includes the dilutive effect of stock options and other potentially dilutive securities such as unvested shares of restricted stock using the treasury stock method, except where the effect of including potential common shares would be anti-dilutive.
For the years ended December 31, 2016, 20152018, 2017 and 2014,2016, there were 175513 thousand, 280364 thousand, and 216175 thousand common stock equivalents, respectively, included in the diluted WASO. For the years ended December 31, 2018, 2017 and 2016, 2015there were nil, 527 thousand and 2014, there was an insignificant amount32 thousand, respectively, of anti-dilutive common stock equivalents.

Treasury Stock
Kforce’sThe Board may authorize share repurchases of Kforce’sour common stock. Shares repurchased under Board authorizations are held in treasury for general corporate purposes, including issuances under the 2009 Employee Stock Purchase Plan. Treasury shares are accounted for under the cost method and reported as a reduction of stockholders’ equity in the accompanying consolidated financial statements.
Derivative Instrument
Our interest rate swap derivative instrument has been designated as a cash flow hedge and is recorded at fair value on the Consolidated Balance Sheets. The effective portion of the gain or loss on the derivative instrument is recorded as a component of Accumulated other comprehensive income (loss), net of tax, and reclassified into earnings when the hedged item affects earnings and into the line item of the hedged item. Any ineffective portion of the gain or loss is recognized immediately into Other expense, net on the Consolidated Statements of Operations and Comprehensive Income. Cash flows from the derivative instrument are classified in the Consolidated Statements of Cash Flows in the same category as the hedged item.
Fair Value Measurements
Kforce usesFair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The fair value measurementshierarchy uses a framework which requires categorizing assets and liabilities into one of three levels based on the inputs used in areasvaluing the asset or liability.
Level 1 inputs are unadjusted, quoted market prices in active markets for identical assets or liabilities.
Level 2 inputs are observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.
Level 3 inputs include unobservable inputs that are supported by little, infrequent or no market activity and reflect management’s own assumptions about inputs used in pricing the asset or liability.
Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
Fair value measurements include, but are not limited to: the impairment testing of goodwill, other intangible assets and intangible andother long-lived assets; stock-based compensation arrangements;compensation; the interest rate swap and a contingent consideration liability. The carrying values of cash and cash equivalents, accounts receivable,trade receivables, other current assets and accounts payable and other current assets andaccrued liabilities approximate fair value because of the short-term nature of these instruments. Using available market information and appropriate valuation methodologies, KforceManagement has determined the estimated fair value measurements; however, considerable judgment is required in interpreting data to develop the estimates of fair value.

New Accounting Standards
In January 2017, the FASB issued authoritative guidance simplifying the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under this guidance, an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance is to be applied for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The guidance requires companies to apply the requirements prospectively. Kforce is currently evaluating the impact on the consolidated financial statements.
In December 2016, the FASB issued authoritative guidance clarifying language when accounting for internal-use software licensed from third parties that is within the scope of Subtopic 350-40. According to the clarifying language, internal-use software licensed from third parties shall be accounted for as the acquisition of an intangible asset. The guidance is to be applied for annual periods beginning after December 15, 2016 and interim periods within those annual periods, and early adoption is permitted. Kforce elected not to adopt this standard early. The guidance requires companies to apply the requirements prospectively or retrospectively. Upon adoption, Kforce anticipates retrospectively applying a change in the classification of internal-use software licensed from third parties from other assets to intangible assets on the consolidated balance sheet.
In August 2016, the FASB issued authoritative guidance clarifying eight cash flow classification issues that are not currently addressed or unclear under current GAAP and thereby reducing the current and potential future diversity in practice. The guidance is to be applied for annual periods beginning after December 15, 2017 and interim periods within those annual periods, and early adoption is permitted. The guidance requires companies to apply the requirements retrospectively, unless it is impracticable to apply the requirements retrospectively at which the requirements should be applied prospectively as of the earliest date practicable. Kforce elected not to adopt this standard early. Kforce does not anticipate that this guidance will have an impact on its consolidated financial statements as the cash flow classification issues are either not applicable or we are currently accounting for them in accordance with the clarified guidance.
In March 2016, the FASB issued authoritative guidance regarding the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is to be applied for annual periods beginning after December 15, 2016 and interim periods within those annual periods, and early adoption is permitted. The guidance requires companies to apply the requirements retrospectively, modified retrospectively, or prospectively depending on the amendment(s) applied. Kforce elected not to adopt this standard early. Upon adoption, Kforce anticipates a prospective impact to our income tax expense line within our consolidated statements of operations and comprehensive income, the amount of which will depend on the vesting activity in any given period and Kforce’s stock price on the vesting date. Additionally, we expect a retrospective change in the presentation of excess tax benefits from a financing to operating activity within our consolidated statements of cash flows. Kforce elected to change its policy regarding forfeitures and to account for forfeitures when they occur as opposed to applying an estimate to simplify our internal accounting practices. This change will be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption.

In February 2016, the FASB issued authoritative guidance regarding the accounting for leases. The guidance is to be applied for annual periods beginning after December 15, 2018 and interim periods within those annual periods, and early adoption is permitted. The guidance requires companies to apply the requirements retrospectively to all prior periods presented, including interim periods. Kforce elected not to adopt this standard early. Kforce is currently evaluating the impact on the consolidated financial statements.
In November 2015, the FASB issued authoritative guidance requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This guidance is to be applied for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and early adoption is permitted. Kforce elected not to adopt this standard early. Kforce anticipates a change to the presentation of the deferred tax liabilities and assets on the consolidated balance sheets upon adoption.Recently Adopted Accounting Standards
In May 2014, the FASB issued authoritative guidance regarding revenue from contracts with customers, which specifies that revenue should be recognized when control of the promised goods or services areis transferred to our customers inat an amount that reflects the consideration to which the company expectswe expect to be entitled to in exchange for those goods or services. Topic 606 is effective for annual and interim reporting periods beginning after December 15, 2017. We adopted Topic 606 using the modified retrospective transition method for all contracts that were not completed as of January 1, 2018. The cumulative impact of adopting Topic 606 was recorded as a reduction to the opening balance of retained earnings of $0.2 million, net of tax, as of January 1, 2018 with the offset recorded as a contract liability. The adjustment is related to a change in the revenue recognition pattern for the performance obligations under certain GS contracts including standard warranty revenues related to our product business and a contract that provides our customer with a material right to a future discount. As of and for the year ended December 31, 2018, the consolidated financial statements were not materially impacted as a result of the application of Topic 606 compared to Topic 605. The comparative information continues to be reported under the accounting standards in effect for the period presented. 
Accounting Standards Not Yet Adopted
In August 2015,2018, the FASB issued authoritative guidance deferringregarding customer's accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. These amendments align the effective daterequirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software, and defer these costs over the noncancelable term of the new revenue standard by one year for all entities. The one-year deferral resultscloud computing arrangements plus any option renewal periods that are reasonably certain to be exercised. This amendment also requires entities to present cash flows, capitalized costs and amortization expense in the same financial statement line items as the service costs incurred for such hosting arrangements. The guidance beingis effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 20172019 with retrospective application or prospective to all implementation costs incurred after the date of adoption. We plan to early adopt this standard in the first quarter of 2019 and entitiesexpect certain presentation changes, which are not permittedexpected to adoptbe material to the standard earlier than the original effective date. Since May 2014,consolidated financial statements.
In August 2018, the FASB has issued additional and amended authoritative guidance regarding revenuechanges to the disclosure requirement for defined benefit plans including additions and deletions to certain disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. The guidance is effective for fiscal periods beginning after December 15, 2020. The adoption of this guidance will modify our disclosures and is not expected to have a material effect on our consolidated financial statements.
In August 2018, the FASB issued authoritative guidance regarding changes to the disclosure requirements for fair value measurement. The amendments on changes in unrealized gains and losses, the weighted average and range of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The guidance is effective for fiscal periods beginning after December 15, 2019. The adoption of this guidance will modify our disclosures and is not expected to have a material effect on our consolidated financial statements.
In February 2018, the FASB issued authoritative guidance regarding the reclassification of certain stranded tax effects from contracts with customers in orderaccumulated other comprehensive income to clarify and improve the understandingretained earnings as a result of the implementation guidance.change in tax rates related to the Tax Cuts and Jobs Act. The guidance permitsis effective for fiscal periods beginning after December 15, 2018 and should be applied either in the period of adoption or retrospectively. Kforce will adopt this standard using the period of adoption method with an adjustment of approximately $168 thousand to retained earnings on January 1, 2019.
In August 2017, the FASB issued authoritative guidance targeting improvements to accounting for hedging activities by simplifying the rules around hedge accounting and improving the disclosure requirements. The guidance is effective for annual periods beginning after December 15, 2018. The hedge accounting guidance should be implemented using a modified retrospective approach for any hedges that exist on the date of adoption, while the presentation and disclosure requirements must be applied prospectively. Kforce will adopt this standard in the first quarter of 2019; it will modify our disclosures but is not expected to have a material effect on our consolidated financial statements.
In June 2016, the FASB issued authoritative guidance on accounting for credit losses on financial instruments, including trade receivables. The guidance requires the application of a current expected credit loss model, which measures credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts. The guidance is effective for annual periods beginning after December 15, 2019. The guidance requires companies to either apply the requirements retrospectivelyusing a modified retrospective approach. We are currently evaluating the potential impact on our consolidated financial statements, especially with respect to all priorour disclosures.

In February 2016, the FASB issued authoritative guidance regarding the accounting for leases, and has since issued subsequent updates to the initial guidance. The amended guidance requires the recognition of assets and liabilities for operating leases with terms longer than 12 months. The guidance is effective for annual periods presented, or apply the requirementsbeginning after December 15, 2018. We will adopt this standard in the yearfirst quarter of 2019 utilizing the optional transition method in the period of adoption through a cumulative adjustment.without retrospective application to comparative periods. We have selected the modified retrospective transition method. Basedanticipate recording approximately $17.6 million and $21.0 million in right-of-use assets and lease liabilities, respectively, on our preliminary assessment, we believe thatconsolidated balance sheets on January 1, 2019. We will take advantage of the timingpackage of our revenue recognition will not be impacted for at least 95% of our revenues. The remainder of our revenues are derived from GS fixed-price contracts. We are reviewing these contracts in order to determine if there may be any change to the timing. Additionally, we anticipate a changepractical expedients permitted in the classification of bad debt expense from SG&A to net service revenues. We are continuing to evaluate other items that may impact our revenue transaction prices. Furthermore, we do anticipate an increase innew standard as well as the level of disclosure around our arrangementspractical expedients for short term leases and resulting revenue recognition.not separating lease and nonlease components.
2. Discontinued OperationsReportable Segments
Effective August 3, 2014,Kforce’s reportable segments are as follows: (1) Tech; (2) FA; and (3) GS. Historically, and for the year ended December 31, 2018, Kforce sold to RCM Acquisition, Inc. (the “Purchaser”), underhas generated only sales and gross profit information on a Stock Purchase Agreement (the “SPA”) dated August 4, 2014, allsegment basis. We do not report total assets or income from continuing operations separately by segment as our operations are largely combined.
For the years ended December 31, 2017 and 2016, our Tech segment included the results of the issued and outstanding stock of KHI,operations for Global, a wholly-owned subsidiary oflocated in Manila, Philippines. During the year ended December 31, 2017, Kforce Inc. and operator of the former HIM reporting segment, for a total cash purchase price of $119.0 million plus a post-closing working capital adjustment of $96 thousand.
In connection withcompleted the sale Kforce entered into a Transition Services Agreement (the “TSA”) withof Global’s assets. This sale did not meet the Purchaser to provide certain post-closing transitional services for a period not to exceed 12 months. Services provided bydefinition of discontinued operations. Kforce under the TSA ceased during the three months ended September 30, 2015. The fees for the services under the TSA were generally equivalent to Kforce’s cost.
In accordance with and defined within the SPA, Kforce was obligated to indemnify the Purchaser for certain losses, as defined, in excess of $1.19 million, although this deductible does not apply to certain specified losses. Kforce’s obligations under the indemnification provisions of the SPA, with the exception of certain items, ceased 12 months from the closing date and were limited to an aggregate of $8.925 million, although these time and monetary caps do not apply to certain specified losses. While it cannot be certain, Kforce believes any material exposure under the indemnification provisions is remote, particularly given that the 12-month time period for general indemnification claims has now passed and, as a result, Kforce has not recorded a liability as$3.3 million gain on sale of December 31, 2015.
The total financial results of HIM have been presented as discontinued operationsGlobal’s assets, which was recorded in Selling, general and administrative expenses within the accompanying Consolidated Statements of Operations and Comprehensive Income.

GS Flex revenue includes 41.9% and 34.3% of revenue recognized from discontinued operations included a gain, net of transaction costs, on the sale of HIM of $94.3 million pretax, or $56.1 million after tax. The transaction costs primarily included legal fees, stock-based compensation related to the acceleration of restricted stock, commissions and transaction bonuses in the form of cash and common stock, which, in the aggregate, totaled $11.0 million. Stock-based compensation related to acceleration of restricted stock was approximately $0.6 million and transaction bonuses was approximately $1.8 million, or 92 thousand shares of common stock. Kforce utilized the proceeds from the sale of HIM initially to pay down the outstanding borrowings under our credit facility and ultimately to repurchase shares of common stock.

5. Income Taxes
The Tax Cuts and Jobs Act was enacted in December 2017, which reduced the U.S. federal corporate tax rate from 35.0% to 21.0% effective January 1, 2018. As a result, we revalued our net deferred income tax assets and recorded $5.4 million of additional Income tax expense in the Consolidated Statement of Operations and $6.3 million, respectively.

The 2018 effective tax rate was favorably impacted by the TCJA. The 2017 effective tax rate was unfavorably impacted due to the revaluation of our net deferred tax assets as a result of TCJA. The 2016 effective tax rate was unfavorably impacted by certain one-time non-cash adjustments. The 2015 rate was unfavorably impacted by a change in the overall mix of income in the various state jurisdictions and the increase in particular uncertain tax positions.

At December 31, 2016,2018, Kforce had approximately $5.6$3.4 million of state tax net operating losses (“NOLs”) which will be carried forward to be offset against future state taxable income. The state tax NOLs expire in varying amounts through 2033.2037.
In evaluating the realizability of Kforce’s deferred tax assets, management assesses whether it is more likely than not that some portion, or all, of the deferred tax assets, will be realized. Management considers, among other things, the ability to generate future taxable income (including reversals of deferred tax liabilities) during the periods in which the related temporary differences will become deductible. The valuation allowance includes a foreign tax credit, which we expect may not be realizable as a result of reduction in our foreign income.
Kforce is periodically subject to IRS audits, as well as state and other local income tax audits for various tax years. During 2018, the IRS commenced an audit for the tax year ended December 31, 2016. No adjustments have been proposed to date. During 2018, the Company also received a notice of examination by the North Carolina Department of Revenue for the years ended December 31, 2016, 2015 and 2015, there were no on-going IRS examinations.2014. No adjustments have been proposed to date. The Company has not received a notice of examination by any other jurisdictions for any other tax year open under statute. Although Kforce has not experienced any material liabilities in the past due to income tax audits, Kforce can make no assurances concerning any future income tax audits.

Kforce and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states. Kforce Global Solutions, Inc. files income tax returns in the Philippines. With a few exceptions, Kforce is no longer subject to federal, state, local, or non-U.S. income tax examinations by tax authorities for years before 2012.2016.

There was no impairment expense related to goodwill for each of the years ended December 31, 2016, 20152018, 2017 and 2014, respectively.2016.
Throughout 2016,2018, we considered the qualitative and quantitative factors associated with each of our reporting units and determined that there was no indication that the carrying values of any of our reporting units were likely impaired.
For ourManagement performed its annual impairment assessment of the carrying value of goodwill for our Technology and Finance and Accounting reporting units as of December 31, 2016 and 2015,2018. For each of our reporting units, we assessed qualitative factors to determine whether the existence of events or circumstances indicated that it was more likely than not that the fair value of the reporting units was less than its carrying amount. We concluded that it was more likely than not that the fair value of these reporting units was more than their carrying amounts.amounts at December 31, 2018.

For our annual impairment assessment ofKforce performed a quantitative analysis for each reporting unit and compared the carrying value of goodwill for our Government Solutions reporting uniteach to the respective estimated fair values as of December 31, 2016 and 2015, we compared its carrying value to the estimated fair value based on a weighting of the income approach and market approaches (“step one”).2017. Discounted cash flows, which serve as the primary basis for the income approach, were based on a discrete financial forecast which was developed by management for planning purposes.management. Cash flows beyond the discrete forecast period of five years were estimated using a terminal value calculation, which incorporated historical and forecasted financial trends and also considered long-term earnings growth rates for publicly-traded peer companies, as well as the risk-free rate of return. The discrete financial forecast includes certain adjustments of costs that Kforce believes a market participant buyer, such as a large government contractor, would incur to operate the Government Solutions reporting unit. The market approaches consistapproach consists of: (1) the guideline company method and (2) the guideline transaction method. The guideline company method applies pricing multiples derived from publicly-traded guideline companies that are comparable to the reporting unit to determine its value. The guideline transaction method applies pricing multiples derived from recently completed acquisitions that we believe are reasonably comparable to the reporting unit to determine fair value. Our assessment indicated thatKforce concluded there were no indications of impairment for its reporting units for the fair value of the Government Solutions reporting unit exceeded its carrying value.year ended December 31, 2017.

8. Credit Facility
On September 20, 2011, Kforce entered into a Third Amended and Restated Credit Agreement, with a syndicate led by Bank of America, N.A. This was amended on March 30, 2012 through the execution of a Consent and First Amendment, on December 27, 2013 through the execution of a Second Amendment and Joinder, and further amended on December 23, 2014 through the execution of a Third Amendment (as amended to date, the “Credit Facility”) resulting in a maximum borrowing capacity of $170.0 million, as well as an accordion option of $50.0 million. The maximum borrowings available to Kforce under the Credit Facility, absent Kforce exercising all or a portion of the accordion, are limited to: (a) a revolving Credit Facility of up to $170.0 million and (b) a $15.0 million sub-limit included in the Credit Facility for letters of credit.
Available borrowings under the Credit Facility are limited to 85% of the net amount of eligible accounts receivable (billed and unbilled), plus 80% of the net amount of eligible employee placement accounts, plus 80% of the appraised market value of the Firm’s corporate headquarters reduced each subsequent quarter by an amount equal to 1/80th of the initial amount, minus certain minimum availability reserves.
Borrowings under the Credit Facility are secured by substantially all of the assets of the Firm, including the Firm’s corporate headquarters property.
Outstanding borrowings under the revolving Credit Facility bear interest at a rate of: (a) LIBOR plus an applicable margin based on various factors; or (b) the higher of (1) the prime rate, (2) the federal funds rate plus 0.50% or (3) LIBOR plus 1.25%. Fluctuations in the ratio of unbilled to billed receivables could result in material changes to availability from time to time. Letters of credit issued under the Credit Facility require Kforce to pay a fronting fee equal to 0.125% of the amount of each letter of credit issued, plus a per annum fee equal to the applicable margin for LIBOR loans based on the total letters of credit outstanding. To the extent that Kforce has unused availability under the Credit Facility, an unused line fee is required to be paid on a monthly basis equal to: (a) if the average daily aggregate revolver outstanding are less than 35% of the amount of the commitments, 0.35% or (b) if the average daily aggregate revolver outstanding are greater than 35% of the amount of the commitments, 0.25% times the amount by which the maximum revolver amount exceeded the sum of the average daily aggregate revolver outstanding, during the immediately preceding month or shorter period if calculated for the first month hereafter or on the termination date.
Under the Credit Facility, Kforce is subject to certain affirmative and negative covenants including, but not limited to, a fixed charge coverage ratio, which is only applicable in the event that the Firm’s availability under the Credit Facility falls below the greater of (a) 10% of the aggregate amount of the commitment of all of the lenders under the Credit Facility and (b) $11 million. The numerator in the fixed charge coverage ratio is defined pursuant to the Credit Facility as earnings before interest expense, income taxes, depreciation and amortization, including the amortization of stock-based compensation expense (disclosed as “Adjusted EBITDA”), less cash paid for capital expenditures. The denominator is defined as Kforce’s fixed charges such as interest expense, principal payments paid or payable on outstanding debt other than borrowings under the Credit Facility, income taxes payable, and certain other payments. This financial covenant, if applicable, requires that the numerator be equal to or greater than the denominator.
Our ability to repurchase equity securities could be limited if the Firm’s availability is less than the greater of (a) 15.0% of the aggregate amount of the commitment of all lenders under the Credit Facility or (b) $15.0 million. Also, our ability to make distributions could be limited if the Firm’s availability is less than the greater of (a) 12.5% of the aggregate amount of the commitment of all lenders under the Credit Facility and (b) $20.6 million. Since Kforce had availability under the Credit Facility of $41.4 million as of December 31, 2016, the fixed charge coverage ratio covenant was not applicable nor was Kforce limited in making distributions or executing repurchases of its equity securities. Kforce believes that it will be able to maintain these minimum availability requirements; however, in the event that Kforce is unable to do so, Kforce could fail the fixed charge coverage ratio, which would constitute an event of default, or we could be limited in our ability to make distributions or repurchase equity securities. The Credit Facility expires December 23, 2019.
As of December 31, 2016 and 2015, $111.5 million and $80.5 million was outstanding under the Credit Facility, respectively. As of February 22, 2017, $117.2 million was outstanding and $35.7 million was available under the Credit Facility.
9. Employee Benefit Plans
401(k) Savings Plans
The Firm maintains various qualified defined contribution 401(k) retirement savings plans for eligible employees. Assets of these plans are held in trust for the sole benefit of employees and/or their beneficiaries. Employer matching contributions are discretionary and are funded annually as approved by Kforce’sthe Board.

Kforce accrued matching 401(k) contributions of $1.5$1.8 million and $1.4$1.6 million as of December 31, 20162018 and 2015,2017, respectively. The plans held a combined 201146 thousand and 218167 thousand shares of Kforce’s common stock as of December 31, 20162018 and 2015,2017, respectively.
Employee Stock Purchase Plan
Kforce’s employee stock purchase plan allows all eligible employees to enroll each quarter to purchase Kforce’s common stock at a 5% discount from its market price on the last day of the quarter. Kforce issued 3419 thousand, 2625 thousand, and 3534 thousand shares of common stock at an average purchase price of $19.37, $22.61$28.93, $20.65, and $19.76$19.37 per share during the years ended December 31, 2016, 20152018, 2017 and 2014,2016, respectively. All shares purchased under the employee stock purchase plan were settled using Kforce’s treasury stock.
Deferred Compensation Plans
The Firm maintains various non-qualified deferred compensation plans, pursuant to which eligible management and highly compensated key employees, as defined by IRS regulations, may elect to defer all or part of their compensation to later years. These amounts are classified in Accounts payable and other accrued liabilities if payable within the next year or in Other long-term liabilities if payable after the next year, upon retirement or termination of employment in the accompanying Consolidated Balance Sheets. At December 31, 20162018 and 2015,2017, amounts related to the deferred compensation plans included in Accounts payable and other accrued liabilities related to the deferred compensation plans totaled $2.7were $1.8 million and $2.3$2.9 million, respectively. Amountsrespectively, and $28.9 million was included in Other long-term liabilities related to the deferred compensation plans totaled $27.5 million and $24.2 million as ofat December 31, 20162018 and 2015, respectively.2017 in the Consolidated Balance Sheets. For the years ended December 31, 20162018, 2017 and 2015,2016, we recognized compensation expense for the plans of $876 thousand, $722 thousand and $881 thousand, and $401 thousand, respectively. For the year ended December 31, 2014, we recognized compensation income from continuing operations for the plans of $187 thousand.
Kforce maintains a Rabbi Trust and holds life insurance policies on certain individuals to assist in the funding of the deferred compensation liability. If necessary, employee distributions are funded through proceeds from the sale of assets held within ourthe Rabbi Trust. The balance of the assets within the Rabbi Trust, including the cash surrender value of the Company-owned life insurance policies, was $27.3$29.1 million and $25.5$31.4 million as of December 31, 20162018 and 2015,2017, respectively, and is recorded in Other assets, net in the accompanying Consolidated Balance Sheets. As of December 31, 2016,2018, the life insurance policies had a cumulative face value of $213.1 million. Kforce had no realized gains or losses attributable to investments in trading securities for the years ended December 31, 2016, 20152018, 2017 and 2014.2016.
Supplemental Executive Retirement Plan
Kforce maintains a SERP for the benefit of certain executive officers. The primary goals of the SERP are to create an additional wealth accumulation opportunity, restore lost qualified pension benefits due to government limitations and retain our covered executive officers. The SERP is a non-qualified benefit plan and does not include elective deferrals of covered executive officers’ compensation.

Normal retirement age under the SERP is defined as age 65; however, certain conditions allow for early retirement as early as age 55 or upon a change in control. Vesting under the plan is defined as 100% upon a participant’s attainment of age 55 and 10 years of service and 0% prior to a participant’s attainment of age 55 and 10 years of service. Full vesting also occurs if a participant with five years or more of service is involuntarily terminated by Kforce without cause or upon death, disability or a change in control. The SERP will be funded entirely by Kforce, and benefits are taxable to the covered executive officer upon receipt and will be deductible by Kforce when paid. Benefits payable under the SERP upon the occurrence of a qualifying distribution event, as defined, are targeted at 45% of the covered executive officers’ average salary and bonus, as defined, from the three years in which the covered executive officer earned the highest salary and bonus during the last 10 years of employment, which is subject to adjustment for retirement prior to the normal retirement age and the participant’s vesting percentage. The benefits under the SERP are reduced for a participant that has not reached age 62 with 10 years of service or age 55 with 25 years of service with a percentage reduction up to the normal retirement age.
Benefits under the SERP are based on the lump sum present value but may be paid over the life of the covered executive officer or 10-year annuity, as elected by the covered executive officer upon commencement of participation in the SERP. None of the benefits earned pursuant to the SERP are attributable to services provided prior to the effective date of the plan. For purposes of the measurement of the benefit obligation as of December 31, 2016,2018, Kforce has assumed that all participants will elect to take the lump sum present value option based on historical trends.

Actuarial Assumptions
Due to the SERP being unfunded as of December 31, 20162018 and 2015,2017, it is not necessary for Kforce to determine the expected long-term rate of return on plan assets. The following table presents the weighted average actuarial assumptions used to determine the actuarial present value of projected benefit obligations at:
 DECEMBER 31,
 2018 2017
Discount rate4.00% 3.25%
Rate of future compensation increase2.90% 2.90%
 DECEMBER 31,
 2016 2015
Discount rate4.00% 4.00%
Rate of future compensation increase3.60% 4.00%

The following table presents the weighted average actuarial assumptions used to determine net periodic benefit cost for the years ended:
 DECEMBER 31,
 2018 2017 2016
Discount rate3.25% 4.00% 4.00%
Rate of future compensation increase2.90% 3.60% 4.00%
 DECEMBER 31,
 2016 2015 2014
Discount rate4.00% 3.75% 3.75%
Rate of future compensation increase4.00% 4.00% 4.00%

The discount rate was determined using the Moody’s Aa long-term corporate bond yield as of the measurement date with a maturity commensurate with the expected payout of the SERP obligation. This rate is also compared against the Citigroup Pension Discount Curve and Liability Index to ensure the rate used is reasonable and may be adjusted accordingly. This index is widely used by companies throughout the U.S. and is considered to be one of the preferred standards for establishing a discount rate.
The assumed rate of future compensation increases is based on a combination of factors, including the historical compensation increases for its covered executive officers and future target compensation levels for its covered executive officers taking into account the covered executive officers’ assumed retirement date.
The periodic benefit cost is based on actuarial assumptions that are reviewed on an annual basis; however, Kforcemanagement monitors these assumptions on a periodic basis to ensure that they accurately reflect current expectations of the cost of providing retirement benefits.

Consistent with the SERP, nonelenders, be increased up to an aggregate additional amount of the benefits earned were attributable to services provided prior$150.0 million (the “Commitment”), which is available to the effectiveFirm in the form of revolving credit loans, swingline loans, and letters of credit. Letters of credit and swingline loans under the Credit Facility are subject to sublimits of $10.0 million. The maturity date of the plan.Credit Facility is May 25, 2022. Borrowings under the Credit Facility are secured by substantially all of the tangible and intangible assets of the Firm, excluding the Firm’s corporate headquarters and certain other designated executed collateral.
DuringRevolving credit loans under the year endedCredit Facility bears interest at a rate equal to: (a) the Base Rate (as described below) plus the Applicable Margin (as described below); or (b) the LIBOR Rate plus the Applicable Margin. Swingline loans under the Credit Facility bears interest at a rate equal to the Base Rate plus the Applicable Margin. The Base Rate is the highest of: (i) the Wells Fargo Bank, National Association prime rate; (ii) the federal funds rate plus 0.50%; or (iii) one-month LIBOR plus 1.00%, and the LIBOR Rate is reserve-adjusted LIBOR for the applicable interest period, but not less than zero. The Applicable Margin is based on the Firm’s total leverage ratio. The Applicable Margin for Base Rate loans ranges from 0.25% to 0.75% and the Applicable Margin for LIBOR Rate loans ranges from 1.25% to 1.75%. The Firm will pay a quarterly non-refundable commitment fee equal to the Applicable Margin on the average daily unused portion of the Commitment (swingline loans do not constitute usage for this purpose). The Applicable Margin for the commitment fee is based on the Firm’s total leverage ratio and ranges between 0.20% and 0.35%.

The Firm is subject to certain affirmative and negative covenants including (but not limited to), the maintenance of a fixed charge coverage ratio of no less than 1.25 to 1.00 and the maintenance of a total leverage ratio of no greater than 3.25 to 1.00. The numerator in the fixed charge coverage ratio is defined pursuant to the Credit Facility as earnings before interest expense, income taxes, depreciation and amortization, stock-based compensation expense and other permitted items pursuant to our Credit Facility (disclosed as “Consolidated EBITDA”), less cash paid for capital expenditures, income taxes and dividends. The denominator is defined as Kforce’s fixed charges such as interest expense and principal payments paid or payable on outstanding debt other than borrowings under the Credit Facility. The total leverage ratio is defined pursuant to the Credit Facility as total indebtedness divided by Consolidated EBITDA. Our ability to make distributions or repurchases of equity securities could be limited if an event of default has occurred. Furthermore, our ability to repurchase equity securities could be limited if: (a) the total leverage ratio is greater than 2.75 to 1.00; and (b) the Firm’s availability, inclusive of unrestricted cash, is less than $25.0 million. At December 31, 2014,2018, Kforce terminatedwas not limited in making distributions and executing repurchases of our equity securities.
As of December 31, 2018 and 2017, $71.8 million and $116.5 million was outstanding, respectively. Kforce had $3.2 million of outstanding letters of credit at December 31, 2018 and 2017 which, pursuant to the Company’s SERHPCredit Facility, reduces the availability.
11. Derivative Instrument and settled all future benefit obligations by making lump sum payments totaling approximately $3.9Hedging Activity
Kforce is exposed to interest rate risk as a result of our corporate borrowing activities. The Firm uses an interest rate swap derivative as a risk management tool to mitigate the potential impact of rising interest rates on variable rate debt.
On April 21, 2017, Kforce entered into a forward-starting interest rate swap agreement with Wells Fargo Bank, N.A. The Swap rate is 1.81%, which is added to our interest rate margin to determine the fixed rate that the Firm will pay to the counterparty during the term of the Swap based on the notional amount of the Swap. The Swap was effective May 31, 2017 and matures April 29, 2022. The notional amount of the Swap is $65.0 million which resulted infor the first three years and decreases to $25.0 million for years four and five.
The Swap has been designated as a net settlement losscash flow hedge and was effective as of $0.7 million recorded in Selling, general and administrative expensesDecember 31, 2018. The change in the correspondingfair value of the Swap was recorded as a component of Accumulated other comprehensive income (loss), net of tax, in the Consolidated Statements of Operations and Comprehensive Income. The termination effectively removed Kforce’s related post-retirement benefit obligation.

10.12. Fair Value Measurements
There were no transfers into or outKforce’s interest rate swap is measured at fair value using readily observable inputs, such as the LIBOR interest rate, which are considered to be Level 2 inputs. Refer to Note 11 - “Derivative Instrument and Hedging Activity” in the Notes to the Consolidated Financial Statements, included in this report for a complete discussion of Level 1, 2 or 3 assets or liabilities during the years ended December 31, 2016 and 2015.Firm’s derivative instrument.

Kforce’s financial statements include aOur contingent consideration liability relatedrelates to a non-significant business acquisition of a business within our Government SolutionsGS reporting segment, which is measured on a recurring basis and is recorded at fair value determined using the discounted cash flow method. The inputs used to calculate the fair value of the contingent consideration liability are considered to be Level 3 inputs due to the lack of relevant market activity and significant management judgment. An increase in future cash flows may result in a higher estimated fair value while a decrease in future cash flows may result in a lower estimated fair value of the contingent consideration liability. Remeasurements to fair value are recorded in Other expense, net within the Consolidated Statements of Operations and Comprehensive Income. For the years ended December 31, 20162018 and 2015,2017, approximately $42$4 thousand and $565 thousand of income, and $321 thousand of expense, respectively, was recognized due to the remeasurement of our contingent consideration liability. The contingent consideration liability is recorded in Other long-term liabilities within the Consolidated Balance Sheets and the estimated fair value as of December 31, 20162018 and 20152017 was $756$187 thousand and $798$191 thousand, respectively.
Certain assets, in specific circumstances, are measured at fair value on a non-recurring basis utilizing Level 3 inputs such as goodwill, other intangible assets and other long-lived assets. For these assets, measurement at fair value in periods subsequent to their initial recognition would be applicable if one or more of these assets were determined to be impaired.

The following table sets forth by level, within the fair value hierarchy, estimated fair values on a recurring basis at December 31, 2018 and 2017 were as follows (in thousands):

11.13. Stock Incentive Plans
On April 19, 2016,18, 2017, the Kforce shareholders approved the 20162017 Stock Incentive Plan (“20162017 Plan”). The 20162017 Plan allows for the issuance of stock options, stock appreciation rights, restricted stock awards (including restricted stock awards (“RSAs”) and restricted stock units (“RSUs”)) and other stock-based awards. The aggregate number of shares of common stock that are subject to awards under the 20162017 Plan is approximately 1.63.0 million shares. The 20162017 Plan terminates on April 19, 2026.18, 2027. Prior to the effective date of the 20162017 Plan, the Company granted stock awards to eligible participants under our 2016 Stock Incentive Plan and 2013 Stock Incentive Plan (“2013 Plan”) and 2006 Stock Incentive Plan (“2006 Plan”(collectively the “Prior Plans”). As of the effective date of the 2016 Plan, noNo additional awards may be granted pursuant to the 2013 Plan and 2006 Plan;Prior Plans; however, awards outstanding as of the effective date will continue to vest in accordance with the terms of the 2013 PlanPrior Plans.
In March 2016, the FASB issued authoritative guidance regarding the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liability, and 2006 Plan, respectively.classification in the statement of cash flows. This guidance was effective for us on January 1, 2017. An entity is allowed to make a policy election as to whether it will include an estimate for awards expected to be forfeited or whether it will account for forfeitures as incurred. The Firm elected to change its policy on accounting for forfeitures and to recognize as incurred. This policy election was applied using a modified retrospective approach with a cumulative-effect adjustment to retained earnings as of the effective date. The impact to the beginning balance of retained earnings was $0.5 million, which is net of taxes of $0.3 million, on January 1, 2017.

Restricted Stock
Restricted stock (including RSAs and RSUs) are granted to executives and management either: (1) for awards related to Kforce’s annual long-term incentive (“LTI”) compensation program, or (2) as part of a compensation package and in order to retain directors, executives and management. The LTI award amounts are generally based on total shareholder return performance goals, which are established by Kforce’s Compensation Committee during the first quarter of the year of performance.goals. The LTI restricted stock granted during the year ended December 31, 20162018 will vest ratably over a period of five years, with equal vesting annually.between three to four years. Other restricted stock granted during the year ended December 31, 20162018 will vest ratably over a period of between one to ten years, with equal vesting annually.
During the three months ended March 31, 2014, the Firm modified all awards containing a performance-acceleration feature that were granted during the three months ended December 31, 2013, as follows: (1) eliminated the performance-acceleration feature and (2) changed the time-based vesting term to five years, with equal vesting annually. The total number of restricted shares impacted by this modification was 268 thousand, excluding already forfeited shares, and the number of employees impacted was 87. The total incremental compensation cost resulting from the modification was $109 thousand, which will be amortized on a straight-line basis over the requisite service period of the modified awards.years.
RSAs contain the same voting rights as other common stock as well as the right to forfeitable dividends in the form of additional RSAs at the same rate as the cash dividend on common stock and containing the same vesting provisions as the underlying award. RSUs contain no voting rights, but have the right to forfeitable dividend equivalents in the form of additional RSUs at the same rate as the cash dividend on common stock and containing the same vesting provisions as the underlying award. The distribution of shares of common stock for each RSU, issued under the 2016 Plan pursuant to the terms of the Kforce Inc. Director’s Restricted Stock Unit Deferral Plan, can be deferred to a date later than the vesting date if an appropriate election was made. In the event of such deferral, vested RSUs have the right to dividend equivalents.

(1)The increase in shares granted during the year ended December 31, 2016 as compared to 2015 and 2014 was due to a change in the grant date practice for our annual LTI awards. For greater clarity, Kforce has historically granted these annual awards on the first business day of the year following the end of the performance period; however, for the performance period ending December 31, 2016 and thereafter, the grant date was shifted to the last day of the performance period. This administrative change resulted in two annual grants being made during the year ended December 31, 2016 (a grant on January 4, 2016 for the performance period ending December 31, 2015 and a grant on December 31, 2016 for the performance period ending December 31, 2016).

(2)The increase in shares vested during the year ended December 31, 2017 was due to a shift in the vesting date of our outstanding annual LTI awards from January 2, 2018 and January 4, 2018 to December 31, 2017 as a tax planning strategy.
The fair market value of restricted stock is determined based on the closing stock price of Kforce’s common stock at the date of grant, and is amortized on a straight-line basis over the requisite service period.
As of December 31, 2016,2018, total unrecognized stock-based compensation expense related to restricted stock was $27.5$29.6 million, which will be recognized over a weighted average remaining period of 4.43.9 years.

Purchase Commitments
Kforce has various commitments to purchase goods and services in the ordinary course of business; thesebusiness. These commitments are primarily related to software and online application licenses and hosting. As of December 31, 2016,2018, these purchase commitments amounted to approximately $14.6$16.3 million and are expected to be paid as follows: $7.4 million in 2017; $4.2 million in 2018; $2.6$10.6 million in 2019; $0.4$3.2 million in 2020; $2.2 million in 2021; and nil$0.3 million in 2021.2022.

Litigation
We are involved in legal proceedings, claims and administrative matters that arise in the ordinary course of our business. We have made accruals with respect to certain of these matters, where appropriate, that are reflected in our consolidated financial statements but are not, individually or in the aggregate, considered material. For other matters for which an accrual has not been made, we have not yet determined that a loss is probable, or the amount of loss cannot be reasonably estimated. While the ultimate outcome of the matters cannot be determined, we currently do not expect that these proceedings and claims, individually or in the aggregate, will have a material effect on our financial position, results of operations, or cash flows. The outcome of any litigation is inherently uncertain, however, and if decided adversely to us, or if we determine that settlement of particular litigation is appropriate, we may be subject to liability that could have a material adverse effect on our financial position, results of operations, or cash flows. Kforce maintains liability insurance in amounts and with such coverage and deductibles as management believes is reasonable. The principal liability risks that Kforce insures against are workers’ compensation, personal injury, bodily injury, property damage, directors’ and officers’ liability, errors and omissions, cyber liability, employment practices liability and fidelity losses. There can be no assurance that Kforce’s liability insurance will cover all events or that the limits of coverage will be sufficient to fully cover all liabilities. Accordingly, we disclose matters below for which a materialLegal costs incurred in connection with loss is reasonably possible.

On August 25, 2016, Kforce Flexible Solutions LLC (along with co-defendant BMO Harris Bank) was served with a complaint brought in the Northern District of Illinois, U.S. District Court, Eastern District of Illinois. Shepard v. BMO Harris Bank N.A. et al., Case No.: 1:16-cv-08288. The plaintiff purports to bring claims on her own behalf and on behalf of putative class of telephone-dedicated workers for alleged violations of the Fair Labor Standards Act, the Illinois Minimum Wage Law, and the Illinois Wage Payment and Collection Act based upon the defendants’ purported failure to pay her and other class members all earned regular and overtime pay for all time worked. More specifically, the plaintiff alleges that class employees were required to perform unpaid work before and after the start and end times of their shifts. She seeks unpaid back regular and overtime wages, liquidated damages, statutory penalties, and attorney fees and costs. Wecontingencies are vigorously defending each of the plaintiff’s claims. At this stage in the litigation it is not feasible to predict the outcome of this matter or reasonably estimate a range of loss, should a loss occur, from this proceeding; however, based on our current knowledge, we believe that the final outcome of this matter is unlikely to have a material adverse effect on our business, consolidated financial position, results of operations, or cash flows.
Income Tax Audits
Kforce is periodically subject to IRS audits,expensed as well as state and other local income tax audits for various tax years. During 2016 and 2015, there were no on-going IRS examinations. Although Kforce has not experienced any material liabilities in the past due to income tax audits, Kforce can make no assurances concerning any future income tax audits.incurred.
Employment Agreements
Kforce has entered into employment agreements with certain executives that provide for minimum compensation, salary and continuation of certain benefits for a six-month to a three-year period after their employment ends under certain circumstances. Certain of the agreements also provide for a severance payment ofranging from one to three times annual salary and one-half to three times average annual bonus if such an agreement is terminated without good cause by Kforce or for good reason by the executive. These agreements containexecutive subject to certain post-employment restrictive covenants. Kforce’s liability atAt December 31, 20162018, our liability would be approximately $43.6$32.6 million if, following a change in control, all of the executives under contract were terminated without good cause by the employer or if the executives resigned for good reason and $17.6$14.1 million if, in the absence of a change in control, all of the executives under contract were terminated by Kforce without good cause or if the executives resigned for good reason.
Kforce has not recorded any liability related to the employment agreements as no events have occurred that would require payment under the agreements.
13. Reportable Segments
Kforce’s reportable segments are as follows: (1) Tech; (2) FA; and (3) GS. This determination is supported by, among other factors: the existence of individuals responsible for the operations of each segment and who also report directly to our chief operating decision maker (“CODM”), the nature of the segment’s operations and information presented to Kforce’s Board and our CODM. Kforce also reports Flex and Direct Hire revenues separately by segment, which has been incorporated into the table below. The following information for the year ended December 31, 2014 has been updated to reflect the disposition of HIM, for which all revenues and gross profit associated with the discontinued operations have been recorded within Income from discontinued operations, net of taxes, in the accompanying Consolidated Statements of Operations and Comprehensive Income.
Historically, and for the year ended December 31, 2016, Kforce has generated only sales and gross profit information on a segment basis. Substantially all operations and long-lived assets are located in the U.S. We do not report total assets or income from continuing operations separately by segment as our operations are largely combined.

CONTROLS AND PROCEDURES.
Evaluation of Disclosure Controls and Procedures
We carried out an evaluation required by Rules 13a-15 and 15d-15 under the Exchange Act (the “Evaluation”), as of the end of the period covered by this report, under the supervision and with the participation of our CEO and CFO, of the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15 and 15d-15 under the Exchange Act (“Disclosure Controls”). Based on the Evaluation, our CEO and CFO concluded that the design and operation of our Disclosure Controls were effective as of December 31, 20162018 to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is: (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to management, including the principal executive officer and the principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Controls
There has not been any change in our internal controls over financial reporting identified in connection with the Evaluation that occurred during the quarter ended December 31, 20162018 that has materially affected, or is reasonably likely to materially affect, those controls.
Inherent Limitations of Internal Control Over Financial Reporting
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.
CEO and CFO Certifications
Exhibits 31.1 and 31.2 are the Certifications of the CEO and the CFO, respectively. The Certifications are required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002 (the “Section 302 Certifications”). This Item of this report, which you are currently reading, is the information concerning the Evaluation referred to in the Section 302 Certifications and this information should be read in conjunction with the Section 302 Certifications for a more complete understanding of the topics presented.

Management Report on Internal Control Over Financial Reporting
The management of Kforce is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) of the Exchange Act. Kforce’s internal control system was designed to provide reasonable assurance to Kforce’s management and the Board of Directors regarding the preparation and fair presentation of published financial statements.
All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.
Under the supervision and with the participation of the CEO and the CFO, Kforce’s management assessed the effectiveness of Kforce’s internal control over financial reporting as of December 31, 2016.2018. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013). Based on our assessment we believe that, as of December 31, 2016,2018, Kforce’s internal control over financial reporting is effective based on those criteria.
Kforce’s independent registered public accounting firm, Deloitte & Touche LLP, has issued an audit report on our internal control over financial reporting, which is presented in Item 8. Financial Statements and Supplementary Data.
