Our team finished the year with strong momentum globally as we executed on plans fundamental to driving consistent growth. The 950+ Accuray team members around the world share a passion for helping to improve the lives of people diagnosed with cancer and our recent commercial momentum is evidence of what a common commitment can achieve. During the fourth quarter of fiscal 2015 our team generated strong order activity for both the CyberKnife® and TomoTherapy® Systems. The Company achieved its highest level of gross orders for any quarter since the acquisition of TomoTherapy in June 2011. We also set a new record for CyberKnife System gross orders in the fourth quarter. With respect to the full fiscal 2015, foreign currency exchange rates negatively impacted our turnaround path. For fiscal 2015 we grew total revenue and gross orders by 3 percent and 2 percent respectively, or 7 percent and 6 percent on a constant currency basis. Gross profit margin for the fiscal year was 38 percent or 40 percent on a constant currency basis. The Company’s adjusted EBITDA was $11.8 million or $23 million on a constant currency basis, which would have represented 77 percent growth. On a positive note, for the full fiscal year operating expenses increased by only 2 percent over fiscal 2014, demonstrating disciplined expense control. One of the more important drivers of orders in fiscal 2015 was the launch of the InCise™ MLC for the Cyberknife M6™ Series. The second half of fiscal 2015, the period during which the InCise MLC was launched, saw substantial improvement in orders compared to the first half of the year. Most importantly, 80 percent of the Q4 fiscal 2015 M6 Series orders included an MLC. Customers recognize the ability of the MLC-equipped CyberKnife M6 to deliver extremely precise radiosurgery and stereotactic body radiation therapy to more patients, in significantly less time than was previously possible with the CyberKnife System. We anticipate CyberKnife System orders will show continued momentum as prospective customers come to understand the vastly improved functionality and clinical capabilities the system can provide. During fiscal 2015, we continued to see market validation for our TomoTherapy System product line in its use as a mainstream radiation therapy solution. During the fourth quarter, approximately 48 percent of TomoTherapy System gross orders were placed by sites with single or dual vaults, which followed approximately 39 percent of gross orders being placed by this type of site during our fiscal third quarter. The TomoTherapy System, through significant improvements in treatment speed and overall throughput, is proving it can address customer requirements for clinical versatility, reliability and efficiency in treating a wide range of radiation oncology patients. As the TomoTherapy System continues to gain clinical recognition as a viable option as an all-purpose radiation therapy device, we believe we will continue to expand our penetration in single and dual vault accounts. We have reported throughout the year on our progress in expanding our commercial footprint in the China market, another key area of commercial focus for us. Of the 39 released class A licenses awarded by the Chinese National Health and Family Planning Commission (NHFPC) for the current quota period from 2013 to 2015, 34 licenses have gone to Accuray products; 20 of these licenses were awarded during fiscal 2015. While the NHFPC has not yet announced any plans related to the next phase of the class A radiotherapy procurement process, we believe there remains a significant growth opportunity for more advanced and technically capable radiotherapy devices based on the currently inadequate levels of served market capacity and strongly increasing patient demand. LOOKING FORWARD As we consider fiscal 2016 and what will continue to drive the Company’s transformation, I believe we now have a solid foundation on which to build. Clinicians value the CyberKnife® and TomoTherapy® Systems for their clinical precision, our ongoing investment in innovation that continues to drive expanded clinical applications for our products, and our vastly improved product reliability and performance. Significant scientific and technological innovations in radiation oncology treatments enable clinicians to better control tumors and provide long-term management of cancer with fewer side effects. Our partnerships with companies such as RaySearch Laboratories and MIM Software, and our ongoing internal R&D initiatives will help us advance our technology portfolio to ensure we continue to meet our customers’ needs. We expect installed base replacement sales or trade-ins to become a larger portion of our overall gross system orders mix going forward, with approximately 30 percent of our installed base reaching their likely replacement cycle over the next 36 months. Driving customer satisfaction, which is a key commercial priority, will be critical to retaining these existing accounts. To that end, we have focused on increasing higher customer satisfaction levels through improved product performance, reliability, and superior service and support. During fiscal 2016 we will continue our efforts to drive sales of our TomoTherapy® and CyberKnife® System while simultaneously evaluating investments in our product portfolio and market development activities. We remain encouraged by our current momentum in China with respect to the class A license category, but will look to expand our opportunities in China through participation in the much larger core product segment. We are proud of the many accomplishments we achieved during fiscal 2015, but we are also aware we have significant work ahead of us in order to create a meaningful change in our business moving forward. Successful execution of our fiscal 2016 plan could be a true inflection point for the company in terms of more consistent commercial momentum, operating profit and cash flow that will result in both business growth and increased shareholder value going forward. I’d like to take this opportunity to thank the global Accuray team for their contributions in fiscal 2015 and the Accuray Board of Directors for their significant guidance and support. Lastly, thank you, our shareholders, for your support in fiscal 2015 and your continued confidence moving forward.

BUSINESS The Company PART I Accuray Incorporated is a radiation oncology company that develops, manufactures, sells and supports precise, innovative treatment solutions which set the standard of radiation therapy care with the aim of helping patients live longer, better lives. Our innovative technologies, the CyberKnife(cid:4) and TomoTherapy(cid:4) Systems, are designed to deliver advanced treatments, including radiosurgery, stereotactic body radiation therapy, intensity modulated radiation therapy, or IMRT, image guided radiation therapy, or IGRT, and adaptive radiation therapy. The CyberKnife Systems and the TomoTherapy Systems are highly complementary, enabling customers to deliver the most precise treatments while minimizing side effects and maximizing patient comfort and care. Each of these systems serves separate patient populations treated by the same medical specialty, radiation oncology, with advanced capabilities. The CyberKnife Systems are fully robotic systems that deliver stereotactic radiosurgery, or SRS, and stereotactic body radiation therapy, or SBRT, and are used to treat multiple types of cancer and tumors throughout the body. The CyberKnife Systems automatically track, detect and correct for tumor and patient movement in real-time during the procedure, enabling delivery of precise, high dose radiation with sub-millimeter accuracy while patients breathe normally, without manual user intervention. Treatment with the CyberKnife Systems requires no anesthesia, and can be performed in one to five staged treatment sessions on an outpatient basis. In addition, the CyberKnife Systems are designed to minimize many of the risks and complications associated with other treatment options. The CyberKnife Systems are the only robotic radiosurgery systems available today which deliver such high precision treatments for intra- and extra-cranial disease sites throughout the body, including prostate, lung, brain, spine, liver, pancreas and kidney. The latest generation CyberKnife M6 Series System is available with the new InCiseTM multi-leaf collimator, or InCise MLC, the world’s first MLC to be available on a robotic platform. With the addition of the InCise MLC, clinicians can deliver the same precise radiosurgery treatments they have come to expect with the CyberKnife systems, while significantly reducing treatment times, for a wider range of tumor types, including larger and different kinds of tumors than were previously treated. Additional options include the fixed collimator, and the 3 iris collimator, giving clinicians a range of collimation forms to choose from to meet the needs of their patients. The TomoTherapy Systems represent the only radiation therapy platform specifically designed for image-guided intensity-modulated radiation therapy, or IG-IMRT. Based on a ring gantry, CT scanner platform, the TomoTherapy System provides continuous delivery of radiation from 360 degrees around the patient, or delivery from clinician-specified direct beam angles. These unique features, combined with daily 3D image guidance, enable physicians to deliver dose distributions which precisely conform to the shape of the patient’s tumor while minimizing dose to normal, healthy tissue, resulting in fewer side effects for patients. The TomoTherapy Systems are capable of treating all standard radiation therapy indications including breast, prostate, lung and head and neck cancers, in addition to complex treatments such as total marrow irradiation, while minimizing side effects, and enable efficient daily imaging to ensure the accuracy of the patient position before each treatment delivery. The latest generation TomoTherapy System is the Tomo H TM Series that includes the following options: TomoHelicalTM, TomoDirectTM, High Performance VoLo TM Planning and TomoEdge dynamic jaws. The system configuration depends on the options chosen by the customer. We also factory refurbish and sell multiple generations of CyberKnife and TomoTherapy Systems. We were incorporated in California in 1990 and commenced operations in 1992. We reincorporated in Delaware in 2007. Our principal offices are located at 1310 Chesapeake Terrace, Sunnyvale, CA 94089, and our telephone number is (408) 716-4600. Market Overview Despite significant improvements in cancer diagnosis and treatment, cancer rates continue to increase globally and are a leading cause of death. According to the International Agency for Research on Cancer, the specialized cancer agency of the World Health Organization, annual cancer rates around the world are projected to increase by over 56% to 22.0 million new cases in the year 2030 from 14.1 million cases in 2012. Cancers can be broadly divided into two groups: solid tumor cancers, which are characterized by the growth of malignant tumors within the body in areas such as the brain, lung, liver, breast or prostate, and hematological, or blood- borne cancers, such as leukemia. The American Cancer Society (ACS) estimates that solid tumor cancers will account for approximately 1.5 million, or approximately 91% of new cancer cases diagnosed annually, and will account for approximately 0.5 million cancer related deaths in the United States in 2015. Traditional methods for the treatment of solid tumor cancers include chemotherapy, surgery and radiation therapy. Currently, the most common type of radiation therapy is external beam radiation therapy, in which patients are treated with high-energy radiation generated by medical equipment external to the patient. Linear accelerators, commonly referred to as linacs, have been widely used for radiation therapy for over 30 years. Linacs represent the largest product segment within the global radiation therapy equipment market which was estimated to have a market size of approximately $3.5 billion in 2014, according to the November 2013 Radiation Therapy Equipment Report by Global Industry Analysts, Inc. increasing preference for non-surgical options is another major factor promoting radiotherapy. Approximately 60% of cancer patients worldwide will undergo some form of radiation therapy during the course of their treatment. While radiation therapy is widely available in the United States and Western Europe, many developing countries currently do not have a sufficient number of linacs to adequately treat their domestic cancer patient populations. We believe increasing demand for advanced medical treatments in many international markets and growth in cancer incidences worldwide will continue to drive demand for advanced linacs in the coming years. 4 Emerging markets are especially underequipped with external beam radiation therapy systems. According to publication in the International Journal of Radiation Oncology Biology and Physics in 2014, radiation therapy is required in more than half of the newly diagnosed cancer patients and of those cured, 40% are by radiotherapy alone or in combination with other modalities. It is estimated that by 2020, the low and middle income countries will need over 9,000 radiation therapy systems. China alone is estimated to have a shortfall of over 3,800 systems because of increasing cancer incidence and an aging population that is estimated to more than double by 2040. Radiation Therapy Radiation therapy is used to treat a wide range of cancer and tumor types by using high-energy radiation to destroy cancer cells and shrink or control the growth of tumors. Radiation therapy works by exposing clusters of cancer cells, or tumors, to a dose of high-energy radiation sufficient to cause cell death and prevent cells from multiplying. During external beam radiation therapy, the clinician’s goal is to target radiation delivery to the tumor as precisely as possible in order to maximize the radiation dose delivered to cancerous tissue and minimize the exposure of healthy tissue. Recent advances in radiation therapy technologies have allowed clinicians to further improve the ability to target the radiation dose more precisely at cancer cells while minimizing the exposure of healthy tissue. These advances include the following: Intensity modulated radiation therapy. modulating, the radiation beam intensity across the treatment area. This technique aims to conform the high dose region of the radiation beam more closely with the shape of the tumor, enabling the delivery of higher doses of radiation to tumors with a reduced impact on surrounding healthy tissue. Intensity modulated radiation therapy involves varying, or Image guided radiation therapy, or IGRT, involves delivering Image guided radiation therapy. radiation guided by images of the treatment area taken shortly before and/or during treatment using CT scan, x-ray, ultrasound or other imaging technologies. By combining imaging with radiation treatment, clinicians can adjust the patient’s position relative to the radiation source prior to each treatment to target the tumor more precisely. Radiosurgery and Stereotactic Body Radiation Therapy. Radiosurgery is a form of radiation therapy that uses precisely targeted radiation to destroy tumors. Radiosurgery is non-invasive; there is no cutting involved. It is commonly used by neurosurgeons to treat conditions within the brain and spine. Stereotactic body radiation therapy is a treatment that uses precisely targeted radiation, like radiosurgery, to destroy tumors located outside the brain and spine. Radiosurgery and stereotactic body radiation therapy typically involve the delivery of a single high dose radiation treatment or a few fractionated radiation treatments (usually up to five) to ablate (destroy) all tissue within the tumor. The ability to deliver high doses of radiation in a single or a few fractions is called hypofractionation, and can only be undertaken with systems that are able to target the tumor with extreme precision and avoid delivering dose to surrounding healthy tissue. To achieve the accuracy and precision required for both radiosurgery and SBRT, image guidance during treatment, the ability to adjust the aim of the beam in real-time and a wide range of beam angles are critical for treatment. Adaptive radiation therapy. Adaptive radiation therapy involves adjusting a patient’s radiation therapy plan during or between fractions to account for changes in the patient’s anatomy, the amount and location of the radiation received by the patient, and the size, shape and location of the tumor. While there is no widely accepted definition of adaptive radiation therapy, it has been characterized to include as little as an adjustment to the physical position of the patient relative to the radiation source prior to treatment, as occurs during IGRT, rather than an adjustment to the treatment plan. Our approach is based on the belief that adaptive radiation therapy requires 5 monitoring and adjustments to the treatment plan facilitated by both the regular acquisition of updated quantitative images showing the location, size, shape and density of the tumor, and verification of the radiation dose received by the patient throughout the entire course of treatment. Hypofractionation. Hypofractionation involves the delivery of higher doses of radiation in fewer fractions than are used in conventional radiation therapy. Higher doses of radiation have been shown to provide greater local control of the tumor. The advent of innovative technological features in radiation therapy treatment planning and delivery has enabled clinicians to maximize the radiation dose administered to tumors in the patient, improving local tumor control and, in some cases, improving patient survival rates. Additional benefits of hypofractionation include minimal side effects, fewer treatments and greater scheduling convenience for the patient. Hypofractionation is generally used to treat tumors that are small and located in specific, sensitive regions of the body, such as the head and neck, spinal cord, lung and prostate, where the very high intensity radiation involved in dose escalation increases the need for a radiation delivery system that is capable of locating tumors and delivering radiation with high precision. Despite advances in radiation therapy techniques, most commercially available radiation therapy systems from other manufacturers still present significant limitations that restrict clinicians’ ability to provide the most precise treatment possible. These limitations include: Limited versatility and precision. The C-arm configuration of traditional radiation therapy systems has a limited range and speed of motion due to its size and mechanical structure. C-arm linac architecture is limited to delivering radiation in a single plane (coplanar) thus limiting its radiation delivery capability for complex and advanced cases. Additionally, most previously existing MLCs, which modulate or shape the radiation beams, have mechanical limitations that reduce their beam-shaping ability and the speed at which they operate. These design elements limit the motion and dynamic range of IMRT intensities capable of being delivered by traditional radiation therapy systems and often make it challenging to achieve the precision needed to maximize dose to the tumor while avoiding damage to healthy tissue and minimizing side effects. These limited treatment angles reduce the ability to deliver precisely targeted radiation that minimizes exposure to healthy tissue. Such imprecision may prevent clinicians from treating tumors near sensitive anatomic structures, such as the eye or the spinal cord, or from re-treating patients in an area of the body that was previously exposed to radiation and may be unable to tolerate additional exposure. Limited ability to provide frequent, quantitative images. Precise radiation therapy requires frequent images that accurately depict the size, shape and location of the tumor. Many traditional radiation therapy systems use imaging technologies that are not generally used on a daily basis to generate a quantitative assessment of the patient’s and/or target volume’s position due to concerns about the additional radiation exposure. In addition, traditional radiation therapy systems measure the amount of radiation emitted by the device based on the system’s performance specifications. This calculation does not provide the clinician with data regarding the amount of radiation that was received by the patient or what tissue within the patient’s body received any particular amount of radiation. Since it is common for internal organs to shift and for the size of the tumor to change during the course of treatment, failure to obtain updated images and adapt the patient and/or plan throughout the course of treatment may result in a portion, or potentially all, of the radiation dose missing the tumor and instead being absorbed by healthy tissue. Failure to integrate multiple functions. The basic architecture for traditional radiation therapy systems pre-dates many recent advances that enable integrated imaging, treatment planning, dose verification or quality assurance capabilities necessary for more advanced treatment protocols. Some conventional systems subsequently have been adapted to include certain elements of this functionality by incorporating modular add-on devices to legacy linac designs. These separate 6 modular components can provide imaging, treatment planning, quality assurance procedures or post-treatment analysis functionality. However, this add-on architectural approach can have safety, accuracy, and workflow implications because of the manual methods used for checking proper system operation. Development of Radiosurgery Advanced radiation therapy systems designed to deliver radiosurgery or stereotactic body radiation therapy differ from traditional radiation therapy systems in that they are designed to deliver a very high cumulative dose of radiation, in a single or a small number of treatments precisely targeted at the tumor rather than at a region that consists of the tumor plus healthy tissue that surrounds the tumor area. The more accurate delivery of radiation allows higher doses to be delivered, increasing the probability of tumor cell death and better local control. In addition, radiosurgery can be administered to patients who have inoperable or surgically complex tumors, or who may prefer a clinically effective, non-surgical treatment option. Our Strategy Our goal is to develop equipment and technology that enable physicians to deliver precise, customized, leading-edge treatment solutions that help cancer patients live longer, better lives. We endeavor to achieve this goal by expanding the clinical options for healthcare providers, helping them offer the best radiation treatment for each patient and by providing patients with treatment tailored to their specific needs. Our vision is a future where the fear, pain and suffering of cancer are a thing of the past. We believe our current technologies and our future innovation can help to achieve this. Some of the key elements of our strategy include the following: Increase physician adoption and patient awareness to drive utilization. We are continually working to increase adoption and awareness of our systems and demonstrate their advantages over more traditional treatment methods. We hold and sponsor symposia and educational meetings and support clinical studies in an effort to demonstrate the clinical benefits of our systems. We regularly meet with clinicians to educate them on the expanded versatility that our systems offer in comparison to more traditional radiation therapy products or surgery. To support awareness of all of our product offerings, we assist our customers to increase patient awareness in their communities by providing them the tools for them to develop marketing and educational campaigns. Continue to expand the radiosurgery market. While radiosurgery has traditionally been used to treat brain tumors, the CyberKnife Systems received U.S. Food and Drug Administration, or FDA, clearance in 2001 to treat tumors anywhere in the body where radiation is indicated. Our system data demonstrate that over 55% of CyberKnife utilization is for cancers and tumors in the body in places other than the brain. There are now hundreds of peer-reviewed publications supporting use of CyberKnife in treatment of various cancer and tumor types. Continue to innovate through clinical development and collaboration. The clinical success of our products is largely the result of the collaborative partnerships we have developed over the last decade with clinicians, researchers and patients. We proactively seek out and rely on constructive feedback from system users to learn what is needed to enhance the technology. As a result of this collaborative process, we continually refine and upgrade our systems, thereby improving our competitive position in the radiation therapy and radiosurgery markets. Upgrades to our systems are designed to address customer needs in the areas of improving the ease of use and accuracy of treatment, decreasing treatment times, and improving utilization for specific types of tumors. Expand sales in international markets. We intend to continue to increase our sales and distribution capabilities outside of the United States to take advantage of the large international opportunity for 7 our products. We currently have regional offices in Morges, Switzerland, Hong Kong, China, Shanghai, China and Tokyo, Japan and direct sales staff in most countries in Western Europe, Japan, India and Canada. Combined with distributors in Eastern Europe, Russia, the Middle East, the Asia Pacific region and Latin America, our sales and distribution channels cover more than 92 countries. However, many of these countries are not highly developed at this time and therefore sales opportunities may be limited. We intend to increase our international revenue by focused additions of direct sales and marketing personnel in targeted areas to further penetrate our most promising international markets, and additional distributors where opportune. Strategic partnerships and joint ventures. We intend to pursue strategic partnerships and joint ventures we believe will allow us to complement our growth strategy, increase sales in our current markets and expand into adjacent markets, broaden our technology and intellectual property and strengthen our relationships with our customers. For example, in fiscal 2011, we completed the acquisition of TomoTherapy Inc., a creator of advanced radiation therapy solutions for cancer care. In July 2012, we completed the acquisition of Morphormics, Inc., a privately-held company based in North Carolina, which is a developer of medical imaging software systems, and in April 2015 we signed an agreement with MIM Software Inc. to further develop adaptive therapy software for TomoTherapy and CyberKnife Systems. Our Products Our suite of products includes the CyberKnife(cid:4) Systems and the TomoTherapy(cid:4) Systems. The CyberKnife Systems Our principal radiosurgery products are the CyberKnife Systems, a robotic full-body radiosurgery system designed to treat tumors anywhere in the body non-invasively, which include the CyberKnife M6 Series with configuration options of fixed collimators plus iris variable aperture collimator (FI), fixed collimators plus the InCise MLC (FM) and fixed collimators plus iris variable aperture collimator plus the InCise MLC (FIM). Using continual image guidance technology and computer controlled robotic mobility, the CyberKnife Systems are designed to deliver precise radiation from a wide array of beam angles and automatically track, detect and correct for tumor and patient movement in real-time throughout the treatment. This design is intended to enable the CyberKnife Systems to deliver high-dose radiation with precision, which minimizes damage to surrounding healthy tissue and eliminates the need for invasive head or body stabilization frames. Our patented image-guidance technology correlates low dose, real-time treatment X-rays with images previously taken with a CT scan of the tumor and surrounding tissue to direct each beam of radiation with increased precision versus treatments without this real-time feedback. This, in turn, enables delivery of a highly conformal, non-isocentric dose of radiation to the tumor, with minimal radiation delivered to surrounding healthy tissue. With its autonomous ability to track, detect and correct for even the slightest tumor and patient movement throughout the entire treatment, the CyberKnife System is intended to provide clinicians with an effective and accurate treatment. Our configurations of CyberKnife Systems include the following: The CyberKnife M6 Series with configurations of FI, FM and FIM. The M6 Series is FDA approved to be used with any of the following options: an iris collimator (I) or a multi-leaf collimator (M). With the InCise MLC, larger tumors previously thought untreatable with radiosurgery and SBRT are able to be treated efficiently and with unrivaled accuracy and tissue sparing. The InCise MLC and IMRT planning tools enable expansion of indications that can be treated with a CyberKnife to include many IMRT indications. The CyberKnife M6(cid:5) Series includes disease-specific tracking and treatment delivery solutions for brain, spine, lung and prostate tumors, treatment speed improvements, more 8 options to configure the treatment room, expanded number of nodes leading to more coverage and sparing of healthy tissue. CyberKnife VSI System. The CyberKnife VSI System comes with fixed collimators or an optional Iris collimator. The VSI System uses an intuitive planning process to enable clinicians to adapt treatment delivery to the distinct characteristics of each patient with continual image guidance. We believe the CyberKnife Systems offer clinicians and patients the following benefits: The only truly robotic system in the market. Combining the benefits of continual image guidance and non-isocentric, non-coplanar treatment delivery, the CyberKnife Systems precisely contour radiation delivery to spare healthy tissue while maintaining sub-millimeter accuracy, even for targets that move during treatment. The CyberKnife Systems are the clinical solution to choose when accuracy, flexibility, efficiency and patient comfort are essential. Treatment of inoperable or surgically complex tumors. The CyberKnife Systems may be used to target tumors that cannot be easily treated with traditional surgical techniques because of their location, number, size, shape or proximity to vital tissues or organs, or because of the age or health of the patient. The CyberKnife Systems’ intelligent robotics enable the precise targeting of a tumor, while at the same time minimizing damage to surrounding healthy tissue. Treatment of tumors throughout the body. The CyberKnife Systems have been cleared by the FDA to provide treatment planning and image-guided radiosurgery treatment for tumors anywhere in the body where radiation treatment is indicated. By comparison, traditional frame-based radiosurgery systems are generally limited to treating brain tumors and use cobalt 60 radioactive material, which decays over time and is difficult to replace. The CyberKnife Systems are being used for the treatment of primary and metastatic tumors outside the brain, including tumors on or near the spine and in the lung, liver, prostate, kidney and pancreas in addition to tumors in the brain, with the same sub-millimeter accuracy in every disease site. Real-time tracking of tumor movement. The CyberKnife Systems are designed to enable the treatment of tumors that change position because of respiration, tumor or patient movement during treatment. The CyberKnife Systems offer the following features which enhance image guided robotic radiation surgery: Synchrony(cid:4) Respiratory Tracking System, Xsight(cid:4) Lung Tracking System, Xsight(cid:4) Spine Tracking System, InTempo(cid:5) Adaptive Imaging System and Lung Optimized Treatment (optional). Significant patient benefits. The CyberKnife Systems maximize patient comfort. Patients may be treated with the CyberKnife Systems on an outpatient basis without anesthesia and without the risks and complications inherent in traditional surgery. Patients do not require substantial pre-treatment preparation, and typically there is little to no recovery time or hospital stay associated with CyberKnife Systems’ treatments. In addition, the CyberKnife Systems eliminate the need for an invasive rigid frame to be screwed into the patient’s skull or affixed to other parts of the body, or for artificial breath holding or gating instruments. Additional revenue generation through increased patient volumes. We believe clinical use of the CyberKnife Systems allows our customers to effectively treat patients where extreme precision and ability to account for motion are important, and patients who otherwise would not have been treated with radiation or who may not have been good candidates for surgery. Upgradeable modular design. The CyberKnife Systems have a modular design, which facilitates the implementation of upgrades that often do not require our customers to purchase an entirely new system to gain the benefits of new features. We continue to work to develop and offer new clinical capabilities enhancing ease of use, reducing treatment times, improving accuracy and improving patient access. The main components and options of the CyberKnife Systems include: the compact X-band 9 linear accelerator; robotic manipulator, the real-time image-guidance system with continuous target tracking and correction; X-ray sources; image detectors. Key features of these components include: Robotic manipulator arm. The robotic manipulator arm, with six-degrees-of-freedom range of movement, is designed to move around the patient to position the linac and direct the radiation with an extremely high level of precision and repeatability. The manipulator arm provides what we believe to be a unique method of positioning the linac to deliver doses of radiation from nearly any direction and position, without the limitations inherent in gantry-based systems, creating a non-isocentric composite dose pattern with a high level of conformance to the shape of each treated tumor. This flexibility enhances the ability to diversify beam trajectories and beam entrance and exit points, helping to minimize risks of radiation damage to healthy cells near the tumor. Furthermore, the rapid response time of the manipulator arm allows tracking of tumors that move with respiration. Real-time image-guidance system with continuous target tracking and correction. Without the need for clinician intervention or treatment interruption, the CyberKnife Systems’ real-time image-guided robotics are designed to enable continuous monitoring and correction for patient and tumor movements throughout each treatment as it is being delivered. X-ray sources. The low-energy X-ray sources generate the X-ray images that help determine the location of bony or other anatomic landmarks, or implanted fiducials, which are used for tracking throughout the entire treatment. Image detectors. The image detectors capture high-resolution anatomical images throughout the treatment. These live images are continually compared to the patient’s CT scan to determine real-time patient positioning. Based on this information, the robotic manipulator automatically corrects for detected movements. In addition to the main components listed above, we also offer the following components and options: Synchrony Respiratory Tracking System; Xsight Spine Tracking System; Xsight Lung Tracking System; Lung Optimized Treatment; RoboCouch(cid:4) Patient Positioning System; Xchange Robotic Collimator Changer; Iris Variable Aperture Collimator; 4D Treatment Optimization and Planning System; InTempo Adaptive Imaging System; MultiPlan(cid:4) Treatment Planning System; MultiPlan MD Suite; CyberKnife Data Management System; MultiPlan Quick Review; Radiosurgery DICOM Interface; Monte Carlo Dose Calculation; Sequential Optimization Treatment Planning; Robotic IMRTTM; AutoSegmentation; QuickPlan; PlanTouchTM; and the InCise MLC. Key features of these components are as follow: Synchrony Respiratory Tracking System. The CyberKnife Systems’ proprietary motion tracking system, the Synchrony Respiratory Tracking System, is the first and only technology to continuously synchronize beam delivery to the motion of the tumor in real time, enabling the delivery of highly conformal radiation beams while reducing healthy tissue exposure. It is used to continuously track tumors that move with respiration as beams are synchronized in real-time to tumor position while adapting to changes in breathing patterns. The Synchrony system provides what we believe is unsurpassed clinical accuracy of approximately 1.5 millimeters for tumors that move with respiration without the need for implanted fiducials. It makes it possible and practical for clinicians to deliver radiation dose with sub-millimeter precision, even for tumors that move with respiration. Iris Variable Aperture Collimator. The Iris Variable Aperture Collimator enables delivery of beams in 12 unique sizes with a single collimator, which significantly reduces treatment times and the total radiation dose delivered to the patient. 4D Treatment Optimization and Planning System. The 4D Treatment Optimization and Planning System is designed to optimize treatment by taking into account the movement of the tumor and the 10 movement and change in shape of the surrounding tissue, thereby minimizing margins and radiation exposure to healthy tissue. MultiPlan Treatment Planning System. The MultiPlan System enables physicians to generate high quality treatment plans for the CyberKnife Systems, through a comprehensive set of planning tools for image fusion, contouring, dose calculation and treatment plan review that can be remotely accessed by a secure connection from outside the clinic. The MultiPlan system uses input images from multiple modalities, including computed tomography, or CT, magnetic resonance imaging, or MRI, positron emission tomography, or PET, and 3D angiography. CyberKnife Data Management System. The results of a patient’s treatment delivery, such as dose delivered from each beam, each path and each fraction, and details about the images acquired and corrections applied are recorded and stored in the data management system and are recorded and stored in the data management system. Radiosurgery DICOM Interface. Data management systems, such as the CyberKnife Data Management System, utilize industry-standard interface protocols, such as DICOM, to export patient information to the OIS. The Radiosurgery DICOM Interface integrates the CyberKnife Systems with oncology departments’ Oncology Information System (OIS) electronic medical record to generate a comprehensive export of the radiosurgery treatment history. Monte Carlo Dose Calculation. Our optional Monte Carlo Dose Calculation software uses Monte Carlo simulation algorithms in treatment planning and dose calculation. Our Monte Carlo dose calculation algorithm can perform the necessary treatment planning calculations in a significantly shorter time frame as compared to conventional Monte Carlo dose calculation methods, thereby accelerating the treatment planning process. QuickPlan. Our QuickPlan(cid:4) technology enables a complete treatment plan to be generated automatically, and the results presented to the user for review. PlanTouch. PlanTouch(cid:5) is the first commercially available, fully integrated software application in radiation oncology that allows physicians to remotely review and approve patients’ radiation treatment plans on the iPad. InCise Multi-leaf Collimator. The InCise MLC is designed specifically for the CyberKnife M6 Series. It delivers the same precise SRS and SBRT treatments clinicians expect from the CyberKnife Systems, while significantly reducing treatment times. With the InCise MLC, the CyberKnife M6 Series can be used to treat larger and irregular tumors more efficiently. The InCise MLC was commercially launched in the US in the third fiscal quarter of 2015 and is currently available in certain approved markets outside of the US. The TomoTherapy Systems The TomoTherapy Systems include the new TomoTherapy H Series with configuration options of TomoH, TomoHD(cid:5) and TomoHDA(cid:5). The TomoTherapy Systems consist of fully integrated and versatile radiation therapy systems used by healthcare professionals in the treatment of a wide range of cancer types. We believe the TomoTherapy Systems offer clinicians and patients the following benefits: Versatile treatment capabilities. The TomoTherapy Systems’ ring gantry platform enables precise and efficient treatments with a high degree of dose conformity. The high-speed binary multi-leaf collimator, or MLC, is integrated with the linac and consists of 64 individual low leakage tungsten leaves that move across the beam to either block or allow the passage of radiation, effectively shaping the beam as it is emitted. The combination of the ring gantry and the high-speed MLC (which we refer to as TomoHelical) allow treatment to be delivered continuously in a 360-degree helical pattern around 11 the patient’s body. Additionally, the TomoDirectTM feature provides the TomoTherapy Systems added versatility to provide high quality, fixed angle beams for those cases suited to simple tangential beam radiation delivery. All TomoTherapy Systems enable an operator to provide non-isocentric three- dimensional conformal image-guided IMRT or stereotactic treatments within a typical cylindrical volume of 80 centimeters in diameter and up to 135 centimeters in length. This expansive treatment field allows large areas of the body to be treated in a single session and the treatment of widely distant tumors. The TomoTherapy Systems’ versatility, efficiency and precision offer clinicians an extensive range of effective treatment possibilities. Daily, quantitative imaging for better identification of tumors, dose verification and treatment planning. The TomoTherapy Systems offer integrated quantitative CT imaging capabilities, which depict the density of tumors and healthy tissue more accurately than traditional radiation therapy systems. Our integrated mega-voltage computed tomography, or MVCT, which we market as our CTrue(cid:5) imaging technology, uses a low-intensity, fan beam CT to collect quantitative images prior to each treatment. These images allow lung tissue, fat, muscle and bone to be clearly distinguished. In addition, because of the low radiation dose involved, the clinician can collect daily, quantitative images, which can be used to monitor changes in the patient’s internal anatomy and quickly adapt the plan if deemed clinically necessary. We believe daily, quantitative, relatively low dose images are essential to optimizing patient treatment by enabling clinicians to adapt the treatment plan in response to anatomical changes. Integrated treatment system for precise radiation delivery. We believe the integration of our CT imaging technology, treatment planning and helical delivery mode of radiation beams enables highly accurate and precise radiation delivery. Our adaptive software allows clinicians to establish at the time of treatment the contours of a tumor and any sensitive structures at risk. The TomoTherapy Systems use a highly efficient dose optimization algorithm to ensure the radiation beam conforms to the patient’s tumor and minimizes exposure to sensitive healthy tissue structures, providing a highly- targeted dose distribution. These features significantly benefit patients by increasing the radiation delivered to cancerous tissues while reducing damage to nearby healthy tissues and minimizing side effects. Efficient clinical workflow for Image Guided Radiation Therapy, or IGRT, and adaptive radiation therapy. The TomoTherapy Systems integrate into a single system all of the key elements for radiation therapy, including treatment planning, CT image-guided patient positioning, treatment delivery, quality assurance and adaptive planning. The imaging and treatment planning capabilities of many traditional systems are more modular or require cumbersome add-ons or separate treatment planning systems that result in clinicians taking more steps between scanning, planning and treatment of patients. Conversely, the integrated CT imaging and treatment features of the TomoTherapy Systems allow clinicians to scan, plan and treat cancer patients efficiently. Daily images can be easily accessed remotely, via our TomoPortal(cid:5) web-enabled interface, to verify patient positioning and collaboratively define patient treatment strategies. Taking advantage of this integration capability, our StatRT(cid:5) software allows the full radiation therapy process—CT scanning, treatment planning and treatment delivery—to be completed rapidly. Low barriers to installation and implementation. All external beam radiation systems must be housed in rooms which have special radiation shielding to capture any radiation not absorbed by the patient. The TomoTherapy Systems’ size and self-contained design allow customers to retrofit them into existing treatment rooms previously used for legacy radiation therapy systems and avoid, or reduce, the significant construction costs that can be associated with building new, larger treatment rooms, which are often required to install many other radiation therapy systems. With both imaging and radiation delivery capabilities in its ring gantry, the TomoTherapy Systems require less space than other linac systems, which use large moving arms to position the linac or incorporate adjacent imaging equipment used for treatment planning. In addition, because the TomoTherapy Systems have an integrated 12 radiation beam stop, which captures radiation that passes through the patient, they require less radiation shielding in treatment room walls as compared to the shielding required by a traditional system. We also preassemble, test and commission each TomoTherapy Systems at our manufacturing facility, and ship the system almost fully assembled. This assembly process typically allows radiation ‘‘beam on’’ within four days after delivery and first patient treatments to begin within 30 to 45 days after delivery. Platform for further technological advancements in adaptive radiation therapy. We believe the TomoTherapy Systems are uniquely positioned to enable truly adaptive radiation therapy because of their unique ability to provide daily, quantitative images, high speed delivery of radiation from fixed beam angles or helically from 360 degrees around the body and real-time verification of the dose received by the patient. We believe the combination of these design features and our integrated treatment planning and optimization software will allow us to continue to enhance the TomoTherapy Systems’ adaptive capabilities to enable clinicians to routinely and easily adjust a patient’s treatment as needed, thereby remaining true to the intent of the original treatment plan. In addition to the functionality listed above, the TomoTherapy Systems may be enhanced with the following product options: TomoDirect Treatment Mode; Planned Adaptive; OIS Connect(cid:5); TomoTherapy Remote Software Solutions (Remote Planning and TomoPortal); TomoQuality Assurance (TQATM) Package; VoLO Technology; TomoEdge Dynamic Jaws. Key features of these options are as follow: TomoDirect Treatment Mode. The TomoDirect mode is a discrete angle, non-rotational delivery mode for the TomoTherapy Systems that allows the user to create a treatment plan that defines up to twelve target-specific gantry angles. Treatment planning is completed rapidly by all beams for each target being delivered sequentially with the couch passing through the bore of the system at an appropriate speed for each gantry angle. The TomoDirect mode enables users to plan and treat routine cases with greater efficiency, while achieving the quality of TomoTherapy’s unique beamlet- based delivery. OIS Connect software option. The OIS Connect software option is a DICOM standard-based solution that provides the ability to interface a TomoTherapy Systems to a compatible OIS. Tomo Quality Assurance (TQA) package. The TQA application offers trending and reporting of many system and dosimetric parameters that allow physicists to monitor the performance of their TomoTherapy Systems. VoLO Technology. The VoLO Technology is a treatment planning system that leverages advanced graphics processing technology and a new calculation algorithm to increase clinical efficiency, throughput and flexibility in developing even the most complex radiation plans. This solution features high-speed parallel processing for both dose calculation and optimization, based on Graphics Processing Unit (GPU) technology. In addition, VoLO represents the first use of a new Non-Voxel Broad Beam (NVBB) calculation algorithm that takes advantage of both the GPU’s unparalleled speed and the TomoTherapy Systems unique beamlet radiation delivery system to develop dose distributions from the perspective of each beamlet (up to tens of thousands in any given plan) as they pass through the patient’s body. VoLO technology empowers clinicians to create highly customized treatment plans in less time, with greater flexibility to work interactively and in real time to efficiently develop the best IMRT treatment plans for even the most complex cases. TomoEdge Dynamic Jaws. TomoEdge is standard on the TomoTherapy HDA model and is also available on H and HD models. By dynamically varying the width of the collimator jaws during treatment delivery, dose to normal tissues immediately adjacent to the tumor is reduced, contributing to the minimization of radiation side effects. Additionally, overall irradiation time is 13 shortened because the jaws are allowed to open more broadly throughout much of the delivery. The resulting gains in treatment quality and speed expand the TomoTherapy Systems clinical and market reach within the conventional and stereotactic radiotherapy spaces. Sales and Marketing In the United States, while we primarily market to customers directly through our sales organization, we also market to customers through sales agents and group purchasing organizations. Outside the United States, we market to customers directly and through distributors. We have sales and service offices in many countries in Europe, Japan and other countries in Asia, Latin America, and throughout the world. In direct sales markets, we employ a combination of territory sales managers, training specialists and marketing managers. Territory sales managers and product specialists are responsible for selling the systems to hospitals and stand-alone treatment facilities. Our marketing managers help market our current products and work with our engineering group to identify and develop upgrades and enhancements for our suite of products. Our training specialists train radiation oncologists, surgeons, physicists, dosimetrists and radiation therapists. We market our products to radiation oncologists, neurosurgeons, general surgeons, oncology specialists and other referring physicians in hospitals and stand-alone treatment facilities. We intend to continue to increase our focus on marketing and education efforts to surgical specialists and oncologists responsible for treating tumors throughout the body. Our marketing activities also include efforts to inform and educate cancer patients about the benefits of the CyberKnife and TomoTherapy Systems. Under our standard distribution agreement, we generally appoint a distributor for a specific country. We typically also retain the right to distribute the CyberKnife and TomoTherapy Systems in such territories, though we remain bound by certain agreements entered into by TomoTherapy prior to our acquisition that did not retain such rights in certain jurisdictions. In most territories, our distributors generally provide the full range of service and sales capabilities, although we may provide installation and service support for certain distributors. Manufacturing We purchase major components for each of our products from outside suppliers, including the robotic manipulator, treatment couches, gantry, magnetrons and computers. We closely monitor supplier quality, delivery performance and conformance to product specifications, and we also expect suppliers to contribute to our efforts to improve our manufacturing cost and quality. Some of the components are obtained from single-source suppliers. These components include the gantry, couch, magnetron and solid state modulator for the TomoTherapy Systems and the robot, couch, magnetron and MLC for the CyberKnife Systems. In most cases, if a supplier was unable to deliver these components, we believe we would be able to find other sources for these components subject to any regulatory qualifications, if required. In the event of a disruption in any of these suppliers’ ability to deliver a component, we would need to secure a replacement supplier. Additionally, any disruption or interruption of the supply of key subsystems could result in increased costs and delays in deliveries of our treatment systems, which could adversely affect our reputation and results of operations. To help mitigate these risks, we negotiate long-term supply contracts or submit long-term orders and forecasts to our single-source suppliers with the goal that our demand can be satisfied and any capacity problem can be mitigated. 14 Currently, we manufacture our CyberKnife and TomoTherapy Systems in Madison, Wisconsin. At the end of the second fiscal quarter of 2015, we completed the transition of the production of our CyberKnife Systems from our Sunnyvale, California facility to our facility in Madison, Wisconsin, except for certain linear accelerator production which remains at our Sunnyvale, California facility. We manufacture the linac for our TomoTherapy Systems at our Chengdu, China facility. Our facilities employ state-of-the-art manufacturing techniques and equipment. The components manufactured at this facility are produced under an International Standard Organization, or ISO, 9001:2008 certified quality management systems. The completed medical devices designed, manufactured, installed, serviced and distributed at our Sunnyvale, Madison and Morges facilities under quality management systems which are compliant to the internationally recognized quality system standard for medical devices ISO, 13485:2003, and the Quality System regulations enforced by the FDA. We believe our manufacturing facilities will be adequate for our expected growth and foreseeable future demands for at least the next three years. The manufacturing processes at our facilities include fabrication, subassembly, assembly, system integration and final testing. Our manufacturing personnel consist of fabricators, assemblers and technicians supported by production engineers as well as planning and supply chain managers. Our quality assurance program includes various quality control measures from inspection of raw material, purchased parts and assemblies through on-line inspection. We have also incorporated lean manufacturing techniques to improve manufacturing flow and efficiency. Lean manufacturing techniques include reducing wasteful and extraneous activities, balancing assembly and test flow, as well as better utilizing production assets and resources. Intellectual Property The proprietary nature of, and protection for, our products, product components, processes and know-how are important to our business. We seek patent protection in the United States and internationally for our systems and other technology where available and when appropriate. We may also in-license the technology, inventions and improvements that we consider important to the development of our business. In addition, we also rely upon trade secrets, know-how, trademarks, copyright protection, as well as confidentiality agreements with employees, consultants and other third parties, to protect our proprietary rights and to develop and maintain our competitive position. As of June 30, 2015, we held exclusive field of use licenses or ownership of approximately 333 U.S. and foreign patents, and approximately 83 U.S. and foreign patent applications. These patents and applications cover various components and techniques incorporated into the CyberKnife and TomoTherapy Systems, or which may be incorporated into new technologies under current development, all of which we believe will allow us to maintain a competitive advantage in the field of radiation therapy systems. We cannot be certain that any patents will be issued from any of our pending patent applications, nor can we be certain that any of our existing patents or any patents that may be granted to us in the future will provide us with protection. We periodically monitor the activities of our competitors and other third parties with respect to their use of intellectual property. Research and Development Continued innovation is critical to our future success. Our current product development activities include projects expanding clinical applications, driving product differentiation, and continually improving the usability, interoperability, reliability, and performance of our products. We continue to seek to develop innovative technologies so that we can increase our sales. Some of our product improvements have been discussed above under the heading ‘‘Products.’’ 15 Research activities strive to enable new product development opportunities by developing new technologies and advancing areas of existing core technology such as next generation linac, adaptive therapy, patient imaging, motion management, or treatment planning capabilities. The modular design of our systems supports rapid development for new clinical capabilities and performance enhancements by generally allowing each subsystem to evolve within the overall platform design. Access to regular product upgrades protects customer investment in the system, facilitates the rapid adoption of new features and capabilities among existing installed base customers, and drives increasing value in our multiyear service plans. These upgrades will generally consist of software and hardware enhancements designed to increase the ease of use of our systems, improve the speed and accuracy of patient treatment and meet other customer needs. As of June 30, 2015, we had 190 employees in our research and development departments. Research and development expenses for the fiscal years ended June 30, 2015, 2014 and 2013 were $55.8 million, $53.7 million and $66.2 million, respectively. We anticipate research and development expenses for fiscal 2016 to be comparable to fiscal 2015. A key component of our research and development program is our collaboration with research programs at selected hospitals, cancer treatment centers, academic institutions and research institutions worldwide. Our agreements with these third-party collaborators generally require us to make milestone- based payments during the course of a particular project and often also require that we make up-front payments to fund initial activities. Generally, we obtain non-exclusive worldwide rights to commercialize results from the collaboration with an option to negotiate an exclusive license. For inventions resulting from the collaboration owned or exclusively licensed by Accuray, we generally grant a royalty-free license for the purpose of continuing the institution’s research and development, and from time to time, we also grant broader licenses. Our research collaboration programs include work on clinical protocols and hardware and software developments. We also work with suppliers to develop new components in order to increase the reliability and performance of our products and seek opportunities to acquire or invest in the research of other parties where we believe it is likely to benefit our existing or future products. Competition The medical device industry in general and the non-invasive cancer treatment field in particular are subject to intense and increasing competition and rapidly evolving technologies. Because our products often have long development and regulatory clearance and approval cycles, we must anticipate changes in the marketplace and the direction of technological innovation and customer demands. To compete successfully, we will need to continue to demonstrate the advantages of our products and technologies over well-established alternative procedures, products and technologies, and convince physicians and other healthcare decision makers of the advantages of our products and technologies. Traditional surgery and other forms of minimally invasive procedures, brachytherapy, chemotherapy and other drugs remain alternatives to the CyberKnife and TomoTherapy Systems. New product sales in this competitive market are primarily dominated by two companies: Elekta AB and Varian Medical Systems, Inc., or Varian. Some manufacturers of standard linac systems, including Varian and Elekta, have products that can be used in combination with body and/or head frame systems and image-guidance systems to perform both radiosurgical and radiotherapy procedures. Other companies that compete with Accuray include Mitsubishi Heavy Industries, BrainLAB AG, and ViewRay Inc. Furthermore, many government, academic and business entities are investing substantial resources in research and development of cancer treatments, including surgical approaches, radiation treatment, MRI-guided radiotherapy systems, proton therapy systems, drug treatment, gene therapy, and other approaches. Successful developments that result in new approaches for the treatment of cancer could reduce the attractiveness of our products or render them obsolete. 16 Our future success will depend in large part on our ability to establish and maintain a competitive position in current and future technologies. Rapid technological development may render the CyberKnife and TomoTherapy Systems and their technologies obsolete. Many of our competitors have or may have greater corporate, financial, operational, sales and marketing resources, and more experience in research and development than we have. We cannot assume that our competitors will not succeed in developing or marketing technologies or products that are more effective or commercially attractive than our products or that would render our technologies and products obsolete or less useful. We may not have the financial resources, technical expertise, marketing, distribution or support capabilities to compete successfully in the future. Our competitive position also depends, among other things, on: (cid:129) Widespread awareness, acceptance and adoption of our products by the radiation oncology and cancer therapy markets; (cid:129) Innovations that improve the effectiveness and productivity of our systems’ treatment processes and enable them to address emerging customer needs; (cid:129) Availability of reimbursement coverage from third-party payors (including insurance companies, governments, and/or others) for procedures performed using our systems; (cid:129) Published, peer-reviewed data supporting the efficacy and safety of our systems; (cid:129) Limiting the time required from proof of feasibility to routine production; (cid:129) Limiting the time period and cost of regulatory approvals or clearances; (cid:129) The manufacture and delivery of our products in sufficient volumes on time, and accurately predicting and controlling costs associated with manufacturing, installation, warranty and maintenance of the products; (cid:129) Our ability to attract and retain qualified personnel; (cid:129) The extent of our intellectual property protection or our ability to otherwise develop proprietary products and processes; (cid:129) Securing sufficient capital resources to expand both our continued research and development, and sales and marketing efforts; and (cid:129) Obtaining and maintaining any necessary United States or foreign regulatory approvals or clearances. Our customers’ equipment purchase considerations typically include reliability, treatment quality, service capabilities, patient throughput, price, payment terms and equipment supplier viability. We believe we compete favorably with our competitors on price and value based upon the technology offered by our treatment systems. We strive to provide a technologically superior product that covers substantially all aspects of radiation therapy to deliver precise treatments with high-quality clinical outcomes that meet or exceed customer expectations. In addition to competition from technologies performing similar functions as our treatment systems, competition also exists for the limited capital expenditure budgets of our customers. For example, our treatment systems may compete with other equipment required by a radiation therapy department for financing under the same capital expenditure budget, which is typically limited. A purchaser, such as a hospital or cancer treatment center, may be required to select between the two items of capital equipment. Our ability to compete may also be adversely affected when purchase decisions are based solely upon price, since our products are premium-priced systems due to their higher level of functionality and performance. 17 US Reimbursement In the United States, healthcare providers that purchase capital equipment such as the CyberKnife and TomoTherapy Systems generally rely on government and private third-party payors for reimbursement for the healthcare treatment and services they provide. Examples of these types of payors include Medicare, Medicaid, private health insurance plans, and health maintenance organizations, which reimburse all or a portion of the cost of treatment, as well as related healthcare services. Reimbursement involves three components: coverage, coding and payment. Coverage There are currently no national coverage determinations in place under Medicare for CyberKnife or TomoTherapy treatment. Coverage criteria for treatment with CyberKnife and TomoTherapy are outlined in local determinations or, in the absence of a formal policy, treatment is covered as long as it is considered reasonable and necessary. The most common indications covered by Medicare in local coverage determinations for robotic radiosurgery are primary and metastatic tumors in the brain, spine, lung, liver, kidney, pancreas, adrenal gland, prostate as well as other cancers that have failed previous treatment. Intensity Modulated Radiation Therapy is generally covered for cancers of the brain, spine, head and neck, prostate, thoracic, abdominal and retroperitoneal regions, other cancers (e.g. breast) meeting certain criteria, and tumors requiring re-irradiation or where dose tolerance may be exceeded with conventional treatment. Commercial payor policies vary with most covering radiosurgery for tumors in the brain, spine, lung, and increasingly prostate. Other indications such as renal, liver, and pancreatic cancers are also covered by some national and local commercial payors. IMRT and 3D Conformal are typically covered by commercial payors for the indications covered by Medicare. Coding The codes that are used to report radiosurgery treatment delivery in 2015 for the hospital outpatient department are Current Procedural Terminology (CPT) codes 77372 and 77373 for single fraction intracranial radiosurgery and single fraction extracranial/multi- session radiosurgery/stereotactic body radiation therapy. For single session cranial SRS, CMS proposes to retain in 2016 the Comprehensive APC (C-APC) it implemented in 2015 for several services delivered on the day of treatment, but will also allow for billing of some ancillary services that will be tracked for two years. For freestanding centers, Centers for Medicare and Medicaid Services (CMS) has retained the robotic radiosurgery Healthcare Common Procedural Codes (HCPCs) G codes that are currently regionally priced by Medicare Contractors and has not proposed prepacing them with the CPT codes 77372 and 77373, currently in use in the hospital outpatient setting. The nonrobotic SRS/SBRT codes 77372 and 77373 have also been maintained as payable codes in the freestanding site of service. In 2015, in the hospital outpatient department, the code historically used to bill for IMRT delivery, 77418, was replaced by two codes to designate simple and complex IMRT; CPT code 77385 for prostate, breast and physical compensator IMRT and 77386 for all other treatments. Prior to 2015, 3D Conformal treatment had typically been billed under multiple CPT codes; 77413 were used by hospitals to bill for TomoTherapy treatment. In 2015, the 3D conformal codes were replaced by codes to designate simple, intermediate and complex 3D-CRT. TomoTherapy is now reported under the complex 3D-CRT code 77413. These codes have been proposed for freestanding centers in 2016 where additional changes are proposed for other ancillary codes, including image guidance codes. We expect all valid delivery codes should be recognized by commercial payers. Other codes are used to report treatment planning, dosimetry, treatment management, and other procedures routinely performed for treating radiosurgery or radiotherapy patients. 18 Payment The majority of procedures using the CyberKnife and TomoTherapy Systems are performed in the hospital outpatient department. Medicare payment for CyberKnife and TomoTherapy procedures delivered in the hospital outpatient setting is developed by CMS, which calculates rates based on costs submitted by hospitals to perform outpatient procedures. Every year, CMS reviews hospital cost data for outpatient procedures, including radiosurgery and radiotherapy, makes adjustments to rates for the following year, and publishes national unadjusted averages for all procedures eligible for payment in this site of service. In 2016 (and 2017) CMS proposes to track, and pay separately, certain ancillary in addition to the comprehensive APC for single session radiosurgery. After two years we expect CMS will likely repackage all services in the C-APC. The changes proposed for 2016, if implemented, would result in an approximate 9% reduction in total technical services for single fraction intracranial SRS over 2015. For single fraction extracranial/multi session SRS/SBRT delivery code (77373), CMS proposes to reduce payment by 11% in 2016, however, changes in ancillary codes results in no significant changes in total payment to hospitals. Payment for treatment with CyberKnife and TomoTherapy Systems are also available in the freestanding center settings. In 2015 and proposed for 2016, the primary treatment delivery codes for robotic radiosurgery are carrier priced under Medicare and range from low payment to payment at parity with hospital outpatient departments to slightly above outpatient rates. TomoTherapy procedures are set by CMS and the American Medical Association nationally, with adjustments to account for geographic market variations. Coding changes proposed for simple and complex IMRT in 2016, if implemented, would result in significant changes in payment, with simple IMRT treatment delivery proposed to decrease 30%. Complex IMRT delivery is proposed to be reduced less significantly at 5%. Coding changes proposed for 3D-CRT would result in a slight increase in payment for treatment delivery of 6% over 2015. Additionally CMS has proposed to bundle the technical component for IMRT image guidance, though the professional component may still be separately paid. The total (technical and professional) is proposed to still be paid for 3D-CRT. Total technical and professional payment for image guidance delivered with 3D-CRT is proposed to increase significantly in 2016 (80%), however, CMS notes conflicting recommendations from the CPT panel and RUC on how to use and value this code. Therefore, the final policy for 2016 may change, which will have an impact on the total payment for 3D-CRT cases. Non robotic SRS/SBRT payment is proposed to increase in 2016 by 8%, primarily due to changes in practice and malpractice expense inputs. CMS has made other proposals including utilization assumptions for linear accelerators (from 50% in 2015 to 60% in 2016 and 70% in 2017) that we expect may have a negative impact on radiation therapy payment in the future. The federal government and Congress review and adjust rates annually, and from time to time consider various Medicare and other healthcare reform proposals that could significantly affect both private and public reimbursement for healthcare services, including radiotherapy and radiosurgery, in hospitals and free-standing clinics. In the past, we have seen our customers’ decision-making process complicated by the uncertainties surrounding reimbursement rates for radiotherapy and radiosurgery in the United States. State government reimbursement for services is determined pursuant to each state’s Medicaid plan, which is established by state law and regulations, subject to requirements of federal law and regulations. Foreign Reimbursement Internationally, reimbursement and healthcare payment systems vary from country to country and include single-payor, government-managed systems as well as systems in which private payors and government-managed systems exist side- by-side. In general, the process of obtaining coverage approvals has been slower outside of the United States. Our ability to achieve adoption of our 19 treatment systems, and significant sales volume in international markets, will depend in part on the availability of reimbursement for procedures performed using our products. Regulatory Matters Domestic Regulation Our products and software are medical devices subject to regulation by the FDA, as well as other regulatory bodies. FDA regulations govern the following activities that we perform and will continue to perform to ensure medical products distributed domestically or exported internationally are safe and effective for their intended uses: (cid:129) Product design and development; (cid:129) Document and purchasing controls; (cid:129) Production and process controls; (cid:129) Labeling and packaging controls; (cid:129) Product storage; (cid:129) Recordkeeping; (cid:129) Servicing; (cid:129) Corrective and preventive action and complaint handling; (cid:129) Pre-market clearance or approval; (cid:129) Advertising and promotion; and (cid:129) Product sales and distribution. FDA pre-market clearance and approval requirements. Unless an exemption applies, each medical device we wish to commercially distribute in the United States will require either 510(k) clearance or pre-market approval from the FDA. The FDA classifies medical devices into one of three classes. Devices deemed to pose lower risks are placed in either class I or II, which requires the manufacturer to submit to the FDA a pre-market notification requesting permission to commercially distribute the device, known as 510(k) clearance. Some low risk devices are exempted from this requirement. Devices deemed by the FDA to pose the greatest risks, such as life-sustaining, life-supporting or implantable devices, or devices deemed not substantially equivalent to a previously cleared 510(k) device, are placed in class III, requiring pre-market approval. All of our current products are class II devices requiring 510(k) clearances. 510(k) clearance pathway. When a 510(k) clearance is required, we must submit a pre-market notification demonstrating that our proposed device is substantially equivalent to a previously cleared and legally marketed 510(k) device or a device that was in commercial distribution before May 28, 1976 for which the FDA has not yet called for the submission of pre-market approval applications, or PMA. By regulation, the FDA is required to clear or deny a 510(k) pre-market notification within 90 days of submission of the application. Clearance generally takes longer as the FDA may require further information, including clinical data, to make a determination regarding substantial equivalence. In January 2002, we received 510(k) clearance for the TomoTherapy Hi-Art System intended to be used as an integrated system for the planning and delivery of IMRT for the treatment of cancer. In August 2008, we received 510(k) clearance for our TomoDirectTM System. In July 1999, we received 510(k) clearance for the CyberKnife System for use in the head and neck regions of the body. In August 2001, we received 510(k) clearance for the CyberKnife System to provide treatment planning and image guided stereotactic radiosurgery and precision radiotherapy for lesions, tumors and conditions anywhere in the body where radiation treatment is indicated. In April 20 2002, we received 510(k) clearance for the Synchrony Motion Tracking System as an option to the CyberKnife System, intended to enable dynamic image guided stereotactic radiosurgery and precision radiotherapy of lesions, tumors and conditions that move under influence of respiration. In October 2012, we received 510(k) clearance for the InCise MLC with clearance from the FDA on July 1, 2015. Pre-market approval (PMA) pathway. A PMA must be submitted to the FDA if the device is not eligible for the 510(k) clearance process. A PMA must be supported by extensive data, including but not limited to, technical, preclinical, clinical trials, manufacturing and labeling to demonstrate reasonable evidence of the device’s safety and efficacy to the FDA’s satisfaction. Currently, no device we have developed and commercialized has required pre-market approval. Product modifications. After a device receives 510(k) clearance or a PMA approval, any modification that could significantly affect its safety or effectiveness, or that would constitute a significant change in its intended use, will require a new clearance or approval. The FDA has issued draft guidance that, if finalized and implemented, will result in manufacturers needing to seek a significant number of new clearances for changes made to legally marketed devices. We have modified aspects of our CyberKnife and TomoTherapy families of products since receiving regulatory clearance, and we have applied for and obtained additional 510(k) clearances for these modifications when we determined such clearances were required. The FDA requires each manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If the FDA disagrees with our determination not to seek a new 510(k) clearance or PMA approval, the FDA may require us to seek 510(k) clearance or PMA approval. The FDA could also require us to cease marketing and distribution and/or recall the modified device until 510(k) clearance or pre-market approval is obtained. Also, in these circumstances, we may be subject to significant regulatory fines or penalties. During our fiscal year ended June 30, 2014, we submitted one 510(k) clearance notification for modifications made to the operation of the CyberKnife System and one 510(k) clearance notification for the TomoTherapy System. The CyberKnife submission was cleared on October 26, 2012 and the TomoTherapy submission was cleared on August 29, 2012. Pervasive and continuing regulation. After a device is placed on the market, numerous regulatory requirements apply. These include: (cid:129) Quality System Regulation, or QSR, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, documentation and other quality assurance procedures during product design and throughout the manufacturing process; (cid:129) Labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved or off-label uses; and (cid:129) Medical device reporting regulations, which require that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur. The FDA has broad post-market and regulatory enforcement powers. We are subject to unannounced inspections by the FDA and the Food and Drug Branch of the California Department of Health Services to determine our compliance with the QSR and other regulations, and these inspections may include the manufacturing facilities of some of our subcontractors. Our Sunnyvale facility, where we manufacture the CyberKnife Systems, was most recently inspected by the FDA in June 2015. The June 2015 inspection resulted in no observations. In addition, our Madison facility, where we manufacture the finished TomoTherapy and CyberKnife Systems, was most recently inspected by the FDA in July 2012. The July 2012 inspection resulted in no observations. We believe we are in 21 substantial compliance with the QSR. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include any of the following sanctions: (cid:129) Fines, injunctions, consent decrees and civil penalties; (cid:129) Recall or seizure of our products; (cid:129) Operating restrictions, partial suspension or total shutdown of production; (cid:129) Refusing our requests for 510(k) clearance or pre-market approval of new products or new intended uses; (cid:129) Withdrawing 510(k) clearance or pre-market approvals that are already granted; and (cid:129) Criminal prosecution. The FDA also has the authority to require us to repair, replace or refund the cost of any medical device that we have manufactured or distributed. If any of these events were to occur, they could have a material adverse effect on our business. Radiological health. Because our CyberKnife and TomoTherapy Systems contain both laser and X-ray components, and because we assemble these components during manufacturing and service activities, we are also regulated under the Electronic Product Radiation Control Provisions of the Federal Food, Drug, and Cosmetic Act. This law requires laser and X-ray products to comply with regulations and applicable performance standards, and manufacturers of these products to certify in product labeling and reports to the FDA that their products comply with all such standards. The law also requires manufacturers to file new product reports, and to file annual reports and maintain manufacturing, testing and sales records, and report product defects. Various warning labels must be affixed. Assemblers of diagnostic X-ray systems are also required to certify in reports to the FDA, equipment purchasers, and where applicable, to state agencies responsible for radiation protection, that diagnostic and/or therapeutic X-ray systems they assemble meet applicable requirements. Failure to comply with these requirements could result in enforcement action by the FDA, which can include injunctions, civil penalties, and the issuance of warning letters. Fraud and abuse laws. We are subject to various federal and state laws pertaining to healthcare fraud and abuse, including anti-kickback laws and physician self-referral laws. Violations of these laws are punishable by significant criminal and civil sanctions, including, in some instances, exclusion from participation in federal and state healthcare programs, including Medicare and Medicaid. Because of the far-reaching nature of these laws, there can be no assurance that we would not be required to alter one or more of our practices to be in compliance with these laws. Evolving interpretations of current laws, or the adoption of new federal or state laws or regulations could adversely affect many of the arrangements we have with customers and physicians. In addition, there can be no assurance that the occurrence of one or more violations of these laws or regulations would not result in a material adverse effect on our financial condition and results of operations. Anti-kickback laws. Our operations are subject to broad and changing federal and state anti-kickback laws. The Office of the Inspector General of the Department of Health and Human Services, or the OIG, is primarily responsible for enforcing the federal Anti-Kickback Statute and generally for identifying fraud and abuse activities affecting government programs. The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, offering or providing remuneration directly or indirectly to induce either the referral of an individual, or the furnishing, recommending, or arranging of a good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid. ‘‘Remuneration’’ has been broadly interpreted to include anything of value, including such items as gifts, discounts, the furnishing of supplies or equipment, credit arrangements, waiver of payments, and providing anything of value at less than fair market value. 22 Penalties for violating the federal Anti-Kickback Statute include criminal fines of up to $25,000 and/or imprisonment for up to five years for each violation, civil fines of up to $50,000 and possible exclusion from participation in federal healthcare programs such as Medicare and Medicaid. Many states have adopted prohibitions similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare services reimbursed by any source, not only by the Medicare and Medicaid programs, and do not include comparable exceptions. The OIG has issued safe harbor regulations which set forth certain activities and business relationships that are deemed safe from prosecution under the federal Anti-Kickback Statute. There are safe harbors for various types of arrangements, including, without limitation, certain investment interests, leases and personal services and management contracts. The failure of a particular activity to comply in all regards with the safe harbor regulations does not mean that the activity violates the federal Anti-Kickback Statute or that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy each applicable safe harbor may result in increased scrutiny by government enforcement authorities such as the OIG. The OIG has identified the following arrangements with purchasers and their agents as ones raising potential risk of violation of the federal Anti- Kickback Statute: (cid:129) Discount and free good arrangements that are not properly disclosed or accurately reported to federal healthcare programs; (cid:129) Product support services, including billing assistance, reimbursement consultation and other services specifically tied to support of the purchased product, offered in tandem with another service or program (such as a reimbursement guarantee) that confers a benefit to the purchaser; (cid:129) Educational grants conditioned in whole or in part on the purchase of equipment, or otherwise inappropriately influenced by sales and marketing considerations; (cid:129) Research funding arrangements, particularly post-marketing research activities, that are linked directly or indirectly to the purchase of products, or otherwise inappropriately influenced by sales and marketing considerations; and (cid:129) Other offers of remuneration to purchasers that are expressly or impliedly related to a sale or sales volume, such as ‘‘prebates’’ and ‘‘upfront payments,’’ other free or reduced-price goods or services, and payments to cover costs of ‘‘converting’’ from a competitor’s products, particularly where the selection criteria for such offers vary with the volume or value of business generated. We have a variety of financial relationships with physicians who are in a position to generate business for us. For example, physicians who own our stock also provide medical advisory and other consulting or collaboration services. Similarly, we have a variety of different types of arrangements with our customers. In the case of our former placement program, certain services and upgrades were provided without additional charge based on procedure volume. In the past, we have also provided loans to our customers. We also provide research or educational grants to customers to support customer studies related to, among other things, our CyberKnife and Tomotherapy Systems. If our past or present operations are found to be in violation of the federal Anti-Kickback Statute or similar government regulations to which we or our customers are subject, we or our officers may be subject to the applicable penalty associated with the violation, including significant civil and criminal penalties, damages, fines, imprisonment, and exclusion from the Medicare and Medicaid programs. The impact of any such violation may lead to curtailment or restructuring of our operations. Any penalties, damages, fines, or curtailment or restructuring of our operations could adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that some of these laws are open to a variety of interpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and 23 damage our reputation. If an enforcement action were to occur, our reputation and our business and financial condition could be harmed, even if we were to prevail or settle the action. Similarly, if the physicians or other providers or entities with which we do business are found to be non- compliant with applicable laws, they may be subject to sanctions, which could also have a negative impact on our business. Transparency laws. The Physician Payment Sunshine Act, or the Sunshine Act, which was enacted by Congress as part of the Patient Protection and Affordable Care Act on December 14, 2011, requires each applicable manufacturer, which includes medical device companies such as Accuray, to track and report to the federal government on an annual basis all payments and other transfers of value from such applicable manufacturer to U.S. licensed physicians and teaching hospitals as well as physician ownership of such applicable manufacturer’s equity, in each case subject to certain statutory exceptions. Such data will be made available by the government on a publicly searchable website. Failure to comply with the data collection and reporting obligations imposed by the Sunshine Act can result in civil monetary penalties ranging from $1,000 to $10,000 for each payment or other transfer of value that is not reported (up to a maximum of $150,000 per reporting period) and from $10,000 to $100,000 for each knowing failure to report (up to a maximum of $1 million per reporting period). In addition, we are subject to similar state and foreign laws related to the tracking and reporting of payments and other transfers of value to healthcare professionals. These laws require or will require that we implement the necessary and costly infrastructure to track and report such payments and transfers of value. Failure to comply with these new tracking and reporting laws could subject us to significant civil monetary penalties. Physician self-referral laws. We are also subject to federal and state physician self-referral laws. The federal Ethics in Patient Referrals Act of 1989, commonly known as the Stark Law, prohibits, subject to certain exceptions, physician referrals of Medicare and Medicaid patients to an entity providing certain ‘‘designated health services’’ if the physician or an immediate family member has any financial relationship with the entity. The Stark Law also prohibits the entity receiving the referral from billing any good or service furnished pursuant to an unlawful referral. In addition, in July 2008, CMS issued a final rule implementing significant amendments to the regulations under the Stark Law. The final rule, which was effective October 1, 2009, imposes additional limitations on the ability of physicians to refer patients to medical facilities in which the physician or an immediate family member has an ownership interest for treatment. Among other things, the rule provides that leases of equipment between physician owners that may refer patients and hospitals must be on a fixed rate, rather than a per use basis. Prior to enactment of the final rule, physician owned entities had increasingly become involved in the acquisition of medical technologies, including the CyberKnife System. In many cases, these entities entered into arrangements with hospitals that billed Medicare for the furnishing of medical services, and the physician owners were among the physicians who referred patients to the entity for services. The rule limits these arrangements and could require the restructuring of existing arrangements between physicians owned entities and hospitals and could discourage physicians from participating in the acquisition and ownership of medical technologies. The final rule also prohibits percentage-based compensation in equipment leases. As a result of the finalization of these regulations, some existing CyberKnife System operators have modified or restructured their corporate or organizational structures. In addition, certain customers that planned to open CyberKnife centers in the United States involving physician ownership have restructured their legal ownership structure. Certain entities were not able to establish viable models for CyberKnife System operation and therefore canceled their CyberKnife System purchase agreements. Accordingly, these regulations have resulted in cancellations of CyberKnife System purchase agreements and could also reduce the attractiveness of medical technology acquisitions, including CyberKnife System purchases, by physician-owned joint ventures or similar entities. As a result, these regulations have had, 24 and could continue to have, an adverse impact on our product sales and therefore on our business and results of operations. A person who engages in a scheme to circumvent the Stark Law’s referral prohibition may be fined up to $100,000 for each such arrangement or scheme. In addition, any person who presents or causes to be presented a claim to the Medicare or Medicaid programs in violations of the Stark Law is subject to civil monetary penalties of up to $15,000 per bill submission, an assessment of up to three times the amount claimed, and possible exclusion from federal healthcare programs such as Medicare and Medicaid. Various states have corollary laws to the Stark Law, including laws that require physicians to disclose any financial interest they may have with a healthcare provider to their patients when referring patients to that provider. Both the scope and exceptions for such laws vary from state to state. Federal False Claims Act. The federal False Claims Act prohibits the knowing filing or causing the filing of a false claim or the knowing use of false statements to obtain payment from the federal government. When an entity is determined to have violated the False Claims Act, it may be required to pay three times the actual damages sustained by the government, plus mandatory civil penalties of between $5,500 and $11,000 for each separate false claim. Suits filed under the False Claims Act, known as ‘‘qui tam’’ actions, can be brought by any individual on behalf of the government and such individuals, sometimes known as ‘‘relators’’ or, more commonly, as ‘‘whistleblowers,’’ may share in any amounts paid by the entity to the government in fines or settlement. In addition, certain states have enacted laws modeled after the federal False Claims Act. Qui tam actions have increased significantly in recent years, causing greater numbers of healthcare companies to have to defend a false claim action, pay fines or be excluded from Medicare, Medicaid or other federal or state healthcare programs as a result of an investigation arising out of such action. We have retained the services of a reimbursement consultant, for which we pay certain consulting fees, to provide us and facilities that have purchased a CyberKnife or TomoTherapy System, with general reimbursement advice. While we believe this will assist our customers in filing proper claims for reimbursement, and even though such consultants do not submit claims on behalf of our customers, the fact that we provide these consultant services could expose us to additional scrutiny and possible liability in the event one of our customers is investigated and determined to be in violation of any of these laws. HIPAA. The Health Insurance Portability and Accountability Act of 1996, or HIPAA, created two new federal crimes: healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private payors. A violation of this statute is a felony and may result in fines, imprisonment or exclusion from government sponsored programs. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. A violation of this statute is a felony and may result in fines or imprisonment. As a participant in the healthcare industry, we are also subject to extensive laws and regulations protecting the privacy and integrity of patient medical information, including privacy and security standards required under HIPAA. The HIPAA privacy standard was amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, enacted as part of the American Recovery and Reinvestment Act of 2009. HITECH significantly increases the civil money penalties for violations of patient privacy rights protected under HIPAA. Although we are not a covered entity under HIPAA, we have entered into agreements with certain covered entities under which we are considered to be a ‘‘business associate’’ under HIPAA. As a business associate, we are required to implement policies, procedures and reasonable and appropriate security measures to protect individually identifiable health information we receive from covered entities. Furthermore, as of February 2010, business associates are now directly subject to regulations under HIPAA, including a new enforcement scheme, criminal and civil penalties for certain violations, and inspection requirements. 25 Foreign Corrupt Practices Act. The United States and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry, including increased United States government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever the United States or another foreign governmental authority concludes that we are not in compliance with applicable laws or regulations, such governmental authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain or seize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees, and can recommend criminal prosecution to the Department of Justice. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of any device or product we manufacture or distribute. We are also potentially subject to the UK Bribery Act, which could also lead to the imposition of civil and criminal fines. Any of the foregoing actions could result in decreased sales as a result of negative publicity and product liability claims, and could have a material adverse effect on our financial condition, results of operations and prospects. International Regulation International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. The time required to obtain clearance or approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may be different. The primary regulatory environment in Europe is that of the European Union and the three additional member states of the European Economic Area, or EEA, which have adopted similar laws and regulations with respect to medical devices. The European Union has adopted numerous directives and the European Committee for Standardization has promulgated standards regulating the design, manufacture, clinical trials, labeling and adverse event reporting for medical devices. Devices that comply with the requirements of the relevant directive will be entitled to bear CE conformity marking, indicating that the device conforms to the essential requirements of the applicable directives and, accordingly, may be commercially distributed throughout the member states of the European Economic Area. The method of assessing conformity to applicable standards and directives depends on the type and class of the product, but normally involves a combination of self-assessment by the manufacturer and a third-party assessment by a notified body, an independent and neutral institution appointed by a European Union member state to conduct the conformity assessment. This relevant assessment may consist of an audit of the manufacturer’s quality system (currently ISO 13485), provisions of the Medical Devices Directive, and specific testing of the manufacturer’s device. In September 2002 and February 2005, Accuray’s and TomoTherapy’s facilities, respectively, were awarded the ISO 13485 certification, which replaces the ISO 9001 and EN 46001 standards, which have been subsequently maintained through periodic assessments, in accordance with the expiration dates of the standards, and we are currently authorized to affix the CE mark to our products, allowing us to sell our products throughout the European Economic Area. We are also currently subject to regulations in Japan. Under the Pharmaceutical Affairs Law in Japan, a pre-market approval necessary to sell, market and import a product, or Shonin, must be obtained from the Ministry of Health, Labor and Welfare, or MHLW, for our products. A Japanese distributor received the first government approval to market the CyberKnife System from MHLW in November 1996. In December 2003, we received approval from the MHLW to market the CyberKnife System in Japan for clinical applications in the head and neck, and a new distributor, Chiyoda Technology Corporation, was appointed to distribute the CyberKnife System. In June 2008, we received approval from the MHLW to market the CyberKnife System for treatments throughout the body where radiation treatment is indicated. On June 30, 2009, our subsidiary, Accuray Japan KK, became the 26 Marketing Authorization Holder in Japan, which allowed the Company to directly sell our products in Japan. In August 2010, we received Shonin approval from MHLW to market the CyberKnife G4 System to treat tumors non-invasively anywhere in the body, inclusive of head and neck. Hi- Art Co. Ltd., the original distributor for TomoTherapy in Japan, received the Shonin approval from the MHLW to market the TomoTherapy System for use as an integrated system for the planning and delivery of IMR for the treatment of cancer in January 2006. The Shonin was transferred to another distributor, Hitachi Medical Corporation in January 2009. During September 2011, Hitachi Medical Corporation received a Shonin approval for the marketing of the TomoHD model. In July 2012, we took over the Shonins and the service operations of the TomoTherapy Systems in Japan from Hitachi Medical Corporation. In March 2014, we received Shonin approval from MHLW for CyberKnife M6 Series as well as the InCise MLC. We are subject to additional regulations in other foreign countries, including, but not limited to, Canada, Taiwan, China, Korea, and Russia in order to sell our products. We intend that either we or our distributors will receive any necessary approvals or clearance prior to marketing our products in those international markets. State Certificate of Need Laws In some states, a certificate of need or similar regulatory approval is required prior to the acquisition of high-cost capital items or the provision of new services. These laws generally require appropriate state agency determination of public need and approval prior to the acquisition of such capital items or addition of new services. Certificate of need regulations may preclude our customers from acquiring one of our systems, and from performing stereotactic radiosurgery procedures using one of our systems. Several of our prospective customers currently are involved in appeals of certificate of need determinations. If these appeals are not resolved in favor of these prospective customers, they may be precluded from purchasing and/or performing services using one of our systems. Certificate of need laws are the subject of continuing legislative activity, and a significant increase in the number of states regulating the acquisition and use of one of our systems through certificate of need or similar programs could adversely affect us. Backlog For a discussion of the Company’s fiscal 2015 backlog, please refer to the section entitled ‘‘Backlog,’’ in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations. Employees As of June 30, 2015, we had 1,010 employees worldwide. None of the employees are represented by a labor union or covered by a collective bargaining agreement. We have never experienced any employment related work stoppages and we believe our relationship with our employees is good.

We operate in a rapidly changing environment that involves significant risks, a number of which are beyond our control. In addition to the other information contained in this Form 10-K, the following discussion highlights some of these risks and the possible impact of these factors on our business, financial condition and future results of operations. If any of the following risks actually occur, our business, financial condition or results of operations may be adversely impacted, causing the trading price of our common stock to decline. In addition, these risks and uncertainties may impact the ‘‘forward-looking’’ statements described elsewhere in this Form 10-K and in the documents incorporated herein by reference. They could affect our actual results of operations, causing them to differ materially from those expressed in ‘‘forward- looking’’ statements. Item 1A. RISK FACTORS Risks Related to Our Business If the CyberKnife or TomoTherapy Systems do not achieve widespread market acceptance, we will not be able to generate the revenue necessary to support our business. Achieving physician, patient, hospital administrator and third-party payor acceptance of the CyberKnife and TomoTherapy Systems as preferred methods of tumor treatment is crucial to our continued success. Physicians will not begin to use or increase the use of the CyberKnife or TomoTherapy Systems unless they determine, based on experience, clinical data and other factors, that the CyberKnife and TomoTherapy Systems are safe and effective alternatives to traditional treatment methods. We often need to educate physicians about the use of stereotactic radiosurgery, IGRT and adaptive radiation therapy, convince healthcare payors that the benefits of the CyberKnife and TomoTherapy Systems and their related treatment processes outweigh their costs and help train qualified physicians in the skilled use of these systems. In addition, we also must educate prospective customers regarding the entire functionality of our radiation therapy systems and their relative benefits compared to alternative products and treatment methods. We have expended and will continue to expend significant resources on marketing and educational efforts to create awareness of stereotactic radiosurgery and Robotic IMRT as well as adaptive radiation therapy and IGRT generally and to encourage the acceptance and adoption of our products for these technologies. We cannot be sure that our products will gain significant market acceptance among physicians, patients and healthcare payors, even if we spend significant time and expense on their education. In addition, the CyberKnife and TomoTherapy Systems are major capital purchases, and purchase decisions are greatly influenced by hospital administrators who are subject to increasing pressures to reduce costs. These and other factors, including the following, may affect the rate and level of market acceptance of each of the CyberKnife and TomoTherapy Systems: (cid:129) the CyberKnife and TomoTherapy Systems’ price relative to other products or competing treatments; (cid:129) our ability to develop new products and enhancements and receive regulatory clearances and approval, if required, to existing products in a timely manner; 28 (cid:129) increased scrutiny by state boards when evaluating certificates of need requested by purchasing institutions; (cid:129) perception by patients, physicians and other members of the healthcare community of the CyberKnife and TomoTherapy Systems’ safety, efficacy, efficiency and benefits compared to competing technologies or treatments; (cid:129) willingness of physicians to adopt new techniques and the ability of physicians to acquire the skills necessary to operate the CyberKnife and TomoTherapy Systems; (cid:129) extent of third-party coverage and reimbursement rates, particularly from Medicare, for procedures using the CyberKnife and TomoTherapy Systems; and (cid:129) development of new products and technologies by our competitors or new treatment alternatives. If the CyberKnife or TomoTherapy Systems are unable to achieve or maintain market acceptance, new orders and sales of our systems would be adversely affected, our revenue levels would decrease and our business would be harmed. We have a large accumulated deficit, may incur future losses and may be unable to achieve profitability. As of June 30, 2015, we had an accumulated deficit of $395.3 million. We may incur net losses in the future, particularly as we improve our selling and marketing activities. Our ability to achieve and sustain long-term profitability is largely dependent on our ability to successfully market and sell the CyberKnife and TomoTherapy Systems, control our costs, and effectively manage our growth. We cannot assure you that we will be able to achieve profitability. In the event we fail to achieve profitability, our stock price could decline. If we do not effectively manage our growth, our business may be significantly harmed. In order to implement our business strategy, we expect continued growth in our infrastructure requirements, particularly as we expand our manufacturing capacities and our sales and marketing capabilities. To manage our growth, we must expand our facilities, augment our management, operational and financial systems, hire and train additional qualified personnel, scale-up our manufacturing capacity and expand our marketing and distribution capabilities. Our manufacturing, assembly and installation process is complex and occurs over many months, and we must effectively scale this entire process to satisfy customer expectations and changes in demand. Further, to accommodate our growth and compete effectively, we will be required to improve our information systems. We cannot be certain that our personnel, systems, procedures and internal controls will be adequate to support our future operations. If we cannot manage our growth effectively, our business will suffer. Our ability to achieve profitability depends in part on maintaining or increasing our gross margins on product sales and services, which we may not be able to achieve. A number of factors may adversely impact our gross margins on product sales and services, including: (cid:129) lower than expected manufacturing yields of high cost components leading to increased manufacturing costs; (cid:129) low production volume which will result in high levels of overhead cost per unit of production; (cid:129) the timing of revenue recognition and revenue deferrals; (cid:129) increased material or labor costs; 29 (cid:129) increased service or warranty costs or the failure to reduce service or warranty costs; (cid:129) increased price competition; (cid:129) variation in the margins across products installed in a particular period; and (cid:129) how well we execute on our strategic and operating plans. If we are unable to maintain or increase our gross margins on product sales and service, our results of operations could be adversely impacted, we may not achieve profitability and our stock price could decline. Our operating results, including our orders, revenues and margins fluctuate and may be unpredictable, which may result in a decline in our stock price if such fluctuations result in a failure to meet the expectations of securities analysts or investors. We have experienced and expect in the future to experience fluctuations in our operating results, including gross orders, revenues and margins, from period to period. Drivers of orders include the introduction and timing of announcement of new products or product enhancements by us and our competitors, as well as changes or anticipated changes in third party reimbursement amounts or policies applicable to treatments using our products. The availability of economic stimulus packages or other government funding, or reductions thereof, may also affect timing of customer purchases. Our products have a high unit price and require significant capital expenditures by our customers. Accordingly, we experience long sales and implementation cycles, which is of greater concern during the current volatile economic environment where we have had customers delaying or cancelling orders. When orders are placed, installation, delivery or shipping, as applicable, is accomplished and the revenues recognized affect our quarterly results. Further, because of the high unit price of the CyberKnife and TomoTherapy Systems and the relatively small number of units sold or installed each quarter, each sale or installation of a CyberKnife or TomoTherapy System can represent a significant percentage of our net orders, backlog or revenue for a particular quarter. Once orders are received and booked into backlog, factors that may affect whether these orders become revenue (or are cancelled or deemed aged-out and reflected as a reduction in net orders) and the timing of revenue include: (cid:129) delays in the customer obtaining funding or financing; (cid:129) delays in construction at the customer site; or (cid:129) delays in the customer obtaining receipt of regulatory approvals such as certificates of need. Our operating results may also be affected by a number of other factors which are outside of our control, including: (cid:129) timing of when we are able to recognize revenue associated with sales of the CyberKnife and TomoTherapy Systems, which varies depending upon the terms of the applicable sales and service contracts; (cid:129) the proportion of revenue attributable to our legacy service plans; (cid:129) timing and level of expenditures associated with new product development activities; (cid:129) regulatory requirements in some states for a certificate of need prior to the installation of a radiation device; (cid:129) delays in shipment due, for example, to unanticipated construction delays at customer locations where our products are to be installed, cancellations by customers, natural disasters or labor disturbances; 30 (cid:129) delays in our manufacturing processes or unexpected manufacturing difficulties; (cid:129) the timing of the announcement, introduction and delivery of new products or product upgrades by us and by our competitors; (cid:129) timing and level of expenditures associated with expansion of sales and marketing activities such as trade shows and our overall operations; and (cid:129) how fluctuations in our gross margins and the factors that contribute to such fluctuations, as described in the Management’s Discussion and Analysis of Financial Condition and Results of Operations. Because many of our operating expenses are based on anticipated sales and a high percentage of these expenses are fixed for the short term, a small variation in the timing of revenue recognition can cause significant variations in operating results from quarter to quarter. Our overall gross margins are impacted by a number of factors described in our risk factor entitled Our ability to achieve profitability depends in part on maintaining or increasing our gross margins on product sales and service, which we may not be able to achieve. If our gross margins fall below the expectation of securities analysts and investors, the trading price of our common stock would almost certainly decline. We report on a quarterly and annual basis our orders and backlog. Unlike revenues, orders and backlog are not defined by GAAP, and are not within the scope of the audit conducted by our independent registered public accounting firm; therefore, investors should not interpret our orders or backlog in such a manner. Also, for the reasons set forth above, our orders and backlog cannot necessarily be relied upon as accurate predictors of future revenues. Order cancellation or significant delays in installation date will reduce our backlog and future revenues, and we cannot predict if or when orders will mature into revenues. Particularly high levels of cancellations or age-outs in one or more periods will make it difficult to compare our operating results. Our orders, backlog, revenues and net earnings in one or more future periods may fall below the expectations of securities analysts and investors, which could cause the trading price of our common stock to decline. If we encounter manufacturing problems, or if our manufacturing facilities do not continue to meet federal, state or foreign manufacturing standards, we may be required to temporarily cease all or part of our manufacturing operations, which would result in delays and lost revenue. The CyberKnife and TomoTherapy Systems are complex, and require the integration of a number of components from several sources of supply. We must manufacture and assemble these complex systems in commercial quantities in compliance with regulatory requirements and at an acceptable cost. Our linac components are extremely complex devices and require significant expertise to manufacture, and we may encounter difficulties in scaling up production of the CyberKnife or TomoTherapy Systems, including problems with quality control and assurance, component supply shortages, increased costs, shortages of qualified personnel, the long lead time required to develop additional radiation-shielded facilities for purposes of testing our products and/or difficulties associated with compliance with local, state, federal and foreign regulatory requirements. If our manufacturing capacity does not keep pace with product demand, we will not be able to fulfill orders in a timely manner, which in turn may have a negative effect on our financial results and overall business. Conversely, if demand for our products decreases, the fixed costs associated with excess manufacturing capacity may adversely affect our financial results. In October 2012, we introduced our new CyberKnife M6 Series Systems that have the option of fixed collimator, iris collimator, and/or multi-leaf collimator, or MLC. The initial supplier producing the MLC for our CyberKnife M6 Series Systems experienced low manufacturing yields and initially delivered only a small number of units. Our initial life-cycle testing revealed that the units did not have the durability that we, and our customers, expect in our products. As a result of these durability 31 concerns and the complexity of the MLC we conducted internal testing and evaluation of the MLC in the field, prior to commercially releasing the MLC to our customers. Despite the delay in the launch of the MLC upgrade, we continued to book orders and install the CyberKnife M6 Series Systems with fixed and iris collimators and now are in the process of fulfilling such orders as capacity permits. The occurrence of new manufacturing and supply issues related to the MLC for our CyberKnife System may adversely affect market acceptance of our CyberKnife M6 System and negatively impact our revenue and overall business. Our manufacturing processes and the manufacturing processes of our third-party suppliers are required to comply with the FDA’s Quality System Regulation, or QSR for any products imported into, or sold within, the USA. The QSR is a complex regulatory scheme that covers the methods and documentation of the design, testing, production process and controls, manufacturing, labeling, quality assurance, packaging, storage and shipping of our products. Furthermore, we are required to verify that our suppliers maintain facilities, procedures and operations that comply with our quality requirements. We are also subject to state licensing and other requirements and licenses applicable to manufacturers of medical devices, and we are required to comply with International Organization for Standardization, or ISO, quality system standards in order to produce products for sale in Europe and Canada, as well as various other foreign laws and regulations. Because our manufacturing processes include the production of diagnostic and therapeutic X-ray equipment and laser equipment, we are subject to the electronic product radiation control provisions of the Federal Food, Drug and Cosmetic Act, which requires that we file reports with the FDA, applicable states and our customers regarding the distribution, manufacturing and installation of these types of equipment. The FDA enforces the QSR and the electronic product radiation control provisions through periodic inspections, some of which may be unannounced. We have been, and anticipate in the future being subject to such inspections. FDA inspections usually occur every two to three years. During such inspections, the FDA may issue Inspectional Observations on Form FDA 483, listing instances where the manufacturer has failed to comply with applicable regulations and procedures, or warning letters. Our Sunnyvale facility, where we manufacture the CyberKnife Systems, was most recently inspected by the FDA in June 2015. The June 2015 inspection resulted in no observations. In addition, our Madison facility, where we manufacture the finished TomoTherapy and CyberKnife Systems, was most recently inspected by the FDA in July 2012. The July 2012 inspection resulted in no observations. If a manufacturer does not adequately address the observations, the FDA may take enforcement action against the manufacturer, including the imposition of fines, restriction of the ability to export product, total shutdown of production facilities and criminal prosecution. If we or a third-party supplier receive a Form FDA 483 with material or major observations that are not promptly corrected, fail to pass a QSR inspection, or fail to comply with these, ISO and other applicable regulatory requirements, our operations could be disrupted and our ability to generate sales could be delayed. Our failure to take prompt and satisfactory corrective action in response to an adverse inspection or our failure to comply with applicable standards could result in enforcement actions, including a public warning letter, a shutdown of our manufacturing operations, a recall of our products, civil or criminal penalties, or other sanctions, which would cause our sales and business to suffer. In addition, because some foreign regulatory approvals are based on approvals or clearances from the FDA, any failure to comply with FDA requirements may also disrupt our sales of products in other countries. We cannot assure you that the FDA or other governmental authorities would agree with our interpretation of applicable regulatory requirements or that we or our third-party suppliers have in all instances fully complied with all applicable requirements. If any of these events occurs, our reputation could be harmed, we could lose customers and there could be a material adverse effect on our business, financial condition and results of operations. If we cannot achieve the required level and quality of production, we may need to outsource production or rely on licensing and other arrangements with third parties who possess sufficient 32 manufacturing facilities and capabilities in compliance with regulatory requirements. Even if we could outsource needed production or enter into licensing or other third-party arrangements, this could reduce our gross margin and expose us to the risks inherent in relying on others. We also cannot assure you that our suppliers will deliver an adequate supply of required components on a timely basis or that they will adequately comply with the QSR. Failure to obtain these components on a timely basis would disrupt our manufacturing processes and increase our costs, which would harm our operating results. Our industry is subject to intense competition and rapid technological change, which may result in products or new tumor treatments that are superior to the CyberKnife and TomoTherapy Systems. If we are unable to anticipate or keep pace with changes in the marketplace and the direction of technological innovation and customer demands, our products may become obsolete or less useful and our operating results will suffer. The medical device industry in general and the non-invasive cancer treatment field in particular are subject to intense and increasing competition and rapidly evolving technologies. Because our products often have long development and government approval cycles, we must anticipate changes in the marketplace and the direction of technological innovation and customer demands. To compete successfully, we will need to continue to demonstrate the advantages of our products and technologies over well-established alternative procedures, products and technologies, and convince physicians and other healthcare decision makers of the advantages of our products and technologies. Traditional surgery and other forms of minimally invasive procedures, brachytherapy, chemotherapy or other drugs remain alternatives to the CyberKnife and TomoTherapy Systems. We consider the competition for the CyberKnife and TomoTherapy Systems to be existing radiation therapy systems, primarily using C-arm linacs, which are sold by large, well-capitalized companies with significantly greater market share and resources than we have. Several of these competitors are also able to leverage their fixed sales, service and other costs over multiple products or product lines. In particular, we compete with a number of existing radiation therapy equipment companies, including Varian Medical Systems, Inc., Elekta AB , Mitsubishi Heavy Industries, Ltd., BrainLAB AG and ViewRay Incorporated. Varian has been the leader in the external beam radiation therapy market for many years and has the majority market share for radiation therapy systems worldwide. In general, because of aging demographics and attractive market factors in oncology, we believe that new competitors will enter the radiosurgery and radiation therapy markets in the years ahead. The CyberKnife System has not typically been used to perform traditional radiation therapy and therefore competition has been limited with conventional medical linacs that perform traditional radiation therapy. However, the CyberKnife VSI System, which we introduced in November of 2009, may be used to perform Robotic IMRT, an advanced method of traditional radiation therapy, which products of Elekta and Varian are also capable of performing. The new CyberKnife M6 Series, which we introduced in October 2012, includes the option of an MLC which may further the use of the CyberKnife Systems to perform radiation therapy, when this feature is commercially available. In October 2012, Varian announced a new line of C-arm gantries, called the Edge systems, which Varian claims are specifically designed for radiosurgery to compete with our CyberKnife Systems. In addition, some manufacturers of conventional linac based radiation therapy systems, including Varian and Elekta, have products that can be used in combination with body and/or head frames and image guidance systems to perform both radiosurgical and radiotherapy procedures. Furthermore, many government, academic and business entities are investing substantial resources in research and development of cancer treatments, including surgical approaches, radiation treatment, MRI-guided radiotherapy systems, proton therapy systems, drug treatment, gene therapy (which is the treatment of disease by replacing, manipulating, or supplementing nonfunctional genes), and other approaches. Successful developments that result in new approaches for the treatment of cancer could reduce the attractiveness of our products or render them obsolete. 33 Our future success will depend in large part on our ability to establish and maintain a competitive position in current and future technologies. Rapid technological development may render the CyberKnife and TomoTherapy Systems and their technologies obsolete. Many of our competitors have or may have greater corporate, financial, operational, sales and marketing resources, and more experience and resources in research and development than we have. We cannot assure you that our competitors will not succeed in developing or marketing technologies or products that are more effective or commercially attractive than our products or that would render our technologies and products obsolete or less useful. We may not have the financial resources, technical expertise, marketing, distribution or support capabilities to compete successfully in the future. Our success will depend in large part on our ability to maintain a competitive position with our technologies. If we are unable to develop new products or enhance existing products, we may be unable to attract or retain customers. Our success depends on the successful development, regulatory clearance or approval, introduction and commercialization of new generations of products, treatment systems, and enhancements to and/or simplification of existing products. The CyberKnife and TomoTherapy Systems, which are currently our principal products, are technologically complex and must keep pace with, among other things, the products of our competitors. We are making significant investments in long-term growth initiatives. Such initiatives require significant capital commitments, involvement of senior management and other investments on our part, which we may be unable to recover. Our timeline for the development of new products or enhancements may not be achieved and price and profitability targets may not prove feasible. Commercialization of new products may prove challenging, and we may be required to invest more time and money than expected to successfully introduce them. Once introduced, new products may adversely impact orders and sales of our existing products, or make them less desirable or even obsolete. Compliance with regulations, competitive alternatives, and shifting market preferences may also impact the successful implementation of new products or enhancements. Our ability to successfully develop and introduce new products, treatment systems and product enhancements and simplifications, and the revenues and costs associated with these efforts, will be affected by our ability to: (cid:129) properly identify customer needs; (cid:129) prove feasibility of new products in a timely manner; (cid:129) educate physicians about the use of new products and procedures; (cid:129) comply with internal quality assurance systems and processes timely and efficiently; (cid:129) limit the timing and cost of obtaining regulatory approvals or clearances; (cid:129) accurately predict and control costs associated with inventory overruns caused by phase-in of new products and phase-out of old products; (cid:129) price new products competitively; (cid:129) manufacture and deliver our products in sufficient volumes on time, and accurately predict and control costs associated with manufacturing, installation, warranty and maintenance of the products; (cid:129) meet our product development plan and launch timelines; (cid:129) improve manufacturing yields of components; and (cid:129) manage customer demands for retrofits of both old and new products. 34 Even if customers accept new products or product enhancements, the revenues from these products may not be sufficient to offset the significant costs associated with making them available to customers. We cannot be sure that we will be able to successfully develop, obtain regulatory approval or clearance for, manufacture or introduce new products, treatment systems or enhancements, the roll-out of which involves compliance with complex quality assurance processes, including QSR. Failure to obtain regulatory approval or clearance for our products or to complete these processes in a timely and efficient manner could result in delays that could affect our ability to attract and retain customers, or could cause customers to delay or cancel orders, causing our backlog, revenues and operating results to suffer. We could become subject to product liability claims, product recalls, other field actions and warranty claims that could be expensive, divert management’s attention and harm our business. Our business exposes us to potential liability risks that are inherent in the manufacturing, marketing and sale of medical device products. We may be held liable if a CyberKnife or TomoTherapy System causes injury or death or is found otherwise unsuitable during usage. Our products incorporate sophisticated components and computer software. Complex software can contain errors, particularly when first introduced. In addition, new products or enhancements may contain undetected errors or performance problems that, despite testing, are discovered only after installation. Because our products are designed to be used to perform complex surgical and therapeutic procedures involving delivery of radiation to the body, defects, even if small, could result in a number of complications, some of which could be serious and could harm or kill patients. Any alleged weaknesses in physician training and services associated with our products may result in unsatisfactory patient outcomes and product liability lawsuits. It is also possible that defects in the design, manufacture or labeling of our products might necessitate a product recall or other field corrective action, which may result in warranty claims beyond our expectations and may harm our reputation and create adverse publicity. A product liability claim, regardless of its merit or eventual outcome, could result in significant legal defense costs. We may also be subject to claims for property damage or economic loss related to, or resulting from, any errors or defects in our products, or the installation, servicing and support of our products, or any professional services rendered in conjunction with our products. The coverage limits of our insurance policies may not be adequate to cover future claims. If sales of our products increase or we suffer future product liability claims, we may be unable to maintain product liability insurance in the future at satisfactory rates or with adequate amounts of coverage. A product liability claim, any product recalls or other field actions or excessive warranty claims, whether arising from defects in design or manufacture or labeling, could negatively affect our sales or require a change in the design, manufacturing process or the indications for which the CyberKnife or TomoTherapy Systems may be used, any of which could harm our reputation and business and result in a decline in revenue. In addition, if a product we designed or manufactured is defective, whether due to design or manufacturing, or labeling defects, improper use of the product or other reasons, we may be required to notify regulatory authorities and/or to recall the product, possibly at our expense. We have voluntarily conducted recalls and product corrections in the past, including one recall for the CyberKnife System in fiscal year 2014. Accuray initiated each of these recalls. While no serious adverse health consequences have been reported in connection with these recalls and the costs associated with each such recall were not material, we cannot ensure that the FDA will not require that we take additional actions to address problems that resulted in previous recalls. A required notification of a correction or removal to a regulatory authority or recall could result in an investigation by regulatory authorities of our products, which could in turn result in required recalls, restrictions on the sale of the products or other civil or criminal penalties. The adverse publicity resulting from any of these actions could cause customers to review and potentially terminate their relationships with us. These 35 investigations, corrections or recalls, especially if accompanied by unfavorable publicity, patient injury or termination of customer contracts, could result in incurring substantial costs, losing revenues and damaging our reputation, each of which would harm our business. Our reliance on single-source suppliers for critical components of the CyberKnife and TomoTherapy Systems could harm our ability to meet demand for our products in a timely and cost effective manner. We currently depend on single-source suppliers for some of the critical components necessary for the assembly of the CyberKnife and TomoTherapy Systems, including, with respect to the CyberKnife System, the robot and imaging detectors, and, with respect to the TomoTherapy Systems, the ring gantry, the solid state modulator, the radiation detector and the magnetron. If any single-source supplier was to cease delivering components to us or fail to provide the components to our specifications and on a timely basis, we might be required to find alternative sources for these components. In some cases, alternative suppliers may be located in the same geographic area as existing suppliers, and are thus subject to the same economic, political, and geographic factors that may affect existing suppliers to meet our demand. We may have difficulty or be unable to find alternative sources for these components. As a result, we may be unable to meet the demand for the CyberKnife or TomoTherapy Systems, which could harm our ability to generate revenue and damage our reputation. Even if we do find alternate suppliers, we will be required to qualify any such alternate suppliers and we would likely experience a lengthy delay in our manufacturing processes or a cessation in production, which would result in delays of shipment to end users. We cannot assure you that our single-source suppliers will be able or willing to meet our future demands. We generally do not maintain large volumes of inventory, which makes us even more susceptible to harm if a single-source supplier fails to deliver components on a timely basis. Furthermore, if we are required to change the manufacturer of a critical component of the CyberKnife or TomoTherapy Systems, we will be required to verify that the new manufacturer maintains facilities, procedures and operations that comply with our quality and applicable regulatory requirements and guidelines, which could further impede our ability to manufacture our products in a timely manner. If the change in manufacturer results in a significant change to the product, a new 510(k) clearance would be necessary, which would likely cause substantial delays. The disruption or termination of the supply of key components for the CyberKnife or TomoTherapy Systems could harm our ability to manufacture our products in a timely manner or within budget, harm our ability to generate revenue, lead to customer dissatisfaction and adversely affect our reputation and results of operations. We depend on key employees, the loss of whom would adversely affect our business. If we fail to attract and retain employees with the expertise required for our business, we may be unable to continue to grow our business. We are highly dependent on the members of our senior management, sales, marketing, operations and research and development staff. Our future success will depend in part on our ability to retain our key employees and to identify, hire and retain additional personnel. Competition for qualified personnel in the medical device industry is intense, and finding and retaining qualified personnel with experience in our industry is very difficult. We believe there are only a limited number of individuals with the requisite skills to serve in many of our key positions and we compete for key personnel with other medical equipment and software manufacturers and technology companies, as well as universities and research institutions. A significant portion of our compensation to our key employees is in the form of stock related grants. A prolonged depression in our stock price could make it difficult for us to retain our employees and recruit additional qualified personnel. We do not maintain, and do not currently intend to obtain, key employee life insurance on any of our personnel. If we fail to hire and retain personnel in key positions, we may be unable to continue to grow our business successfully. 36 Disruption of critical information systems could harm our business and financial condition. Information technology helps us operate more efficiently, interface with customers, maintain financial accuracy and efficiency, and accurately produce our financial statements. If we do not allocate and effectively manage the resources necessary to build, sustain and secure the proper technology infrastructure, we could be subject to transaction errors, processing inefficiencies, the loss of customers, business disruptions, or the loss of or damage to intellectual property through a security breach. In addition, we have moved some of our data and information to a cloud computing system, where applications and data are hosted, accessed and processed through a third-party provider over a broadband Internet connection. In a cloud computing environment, we could be subject to outages and security breaches by the third-party service provider. If our data management systems do not effectively collect, store, process and report relevant data for the operation of our business, whether due to equipment malfunction or constraints, software deficiencies, computer viruses, security breaches, catastrophic events or human error, our ability to effectively plan, forecast and execute our business plan and comply with applicable laws and regulations will be impaired, perhaps materially. Any such impairment could materially and adversely affect our financial condition, results of operations, cash flows and the timeliness with which we internally and externally report our operating results. Likewise, data privacy breaches by employees and others with permitted access to our systems may pose a risk that sensitive data may be exposed to unauthorized person or to the public. There can be no assurance that any efforts we make to prevent against such privacy breaches will prevent breakdowns or breaches in our systems that could adversely affect our business. Moreover, we manufacture and sell products that allow our customers to store confidential information about their patients. We do not have measures to secure our customers’ equipment or any information stored in our customers’ systems or at their locations, which is the responsibility of our customers. A breach of network security and systems or other events that cause the loss or public disclosure of, or access by third parties to, sensitive information stored by us or our customers could have serious negative consequences for our business, including possible fines, penalties and damages, reduced demand for our solutions, an unwillingness of our customers to use our solutions, harm to our reputation and brand, and time-consuming and expensive litigation, any of which could have an adverse effect on our financial results. If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results. As a result, current and potential stockholders could lose confidence in our financial reporting, which could have an adverse effect on our business and our stock price. Effective internal controls are necessary for us to provide reliable financial reports and to protect from fraudulent, illegal or unauthorized transactions. If we cannot maintain effective controls and provide reliable financial reports, our business and operating results could be harmed. A failure to implement and maintain effective internal control over financial reporting could result in a material misstatement of our financial statements or otherwise cause us to fail to meet our financial reporting obligations. This, in turn, could result in a loss of investor confidence in the accuracy and completeness of our financial reports, which could have an adverse effect on our business and operating results and our stock price, and we could be subject to stockholder litigation. We may have difficulties in determining the effectiveness of our internal controls due to our complex financial model. The complexity of our financial model contributes to our need for effective financial reporting systems and internal controls. We recognize revenue from a range of transactions including CyberKnife and TomoTherapy Systems sales and services. The CyberKnife and TomoTherapy Systems are complex products that contain both hardware and software elements. The complexity of the CyberKnife and 37 TomoTherapy Systems and of our financial model pertaining to revenue recognition requires us to process a broader range of financial transactions than would be required by a company with a less complex financial model. Accordingly, deficiencies or weaknesses in our internal controls would likely impact us more significantly than they would impact a company with a less complex financial model. If we were to find that our internal controls were deficient, and/or we would be required to amend or restate historical financial statements, this would likely have a negative impact on our stock price. If third-party payors do not provide sufficient coverage and reimbursement to healthcare providers for use of the CyberKnife and TomoTherapy Systems, demand for our products and our revenue could be adversely affected. Our customers rely significantly on reimbursement from public and private third-party payors for CyberKnife and TomoTherapy systems procedures. Our ability to commercialize our products successfully will depend in significant part on the extent to which public and private third-party payors provide adequate coverage and reimbursement for procedures that are performed with our products. Third-party payors, and in particular managed care organizations, challenge the prices charged for medical products and services and institute cost containment measures to control or significantly influence the purchase of medical products and services. If reimbursement policies or other cost containment measures are instituted in a manner that significantly reduces the coverage or payment for the procedures that are performed with our products, our existing customers may not continue using our products or may decrease their use of our products, and we may have difficulty obtaining new customers. Such actions would likely have a material adverse effect on our operating results. On October 31, 2014, the Centers for Medicare and Medicaid Services (CMS) issued the final rule for 2015 Medicare payment rates for hospital outpatient services, physicians, and services performed in the freestanding center setting. The final rule included certain proposals that impact reimbursement rates for radiation therapy services, such as changes to previous coding structures for IMRT and 3D conformal delivery and development of a comprehensive ambulatory payment classification for single fraction cranial radiosurgery. While these coding changes were implemented in 2015 they have resulted in no significant differences in reimbursement for services delivered with our products. CMS reviews reimbursement rates annually and may implement significant changes in future years, which could discourage existing and potential customers from purchasing or using our products. The safety and efficacy of our products for certain uses is not yet supported by long-term clinical data, and our products may therefore prove to be less safe and effective than initially thought. Although we believe that the CyberKnife and TomoTherapy Systems have advantages over competing products and technologies, we do not have sufficient clinical data demonstrating these advantages for all tumor indications. In addition, we have only limited five-year patient survival rate data, which is a common long-term measure of clinical effectiveness in cancer treatment. We also have limited clinical data directly comparing the effectiveness of the CyberKnife Systems to other competing systems. Future patient studies or clinical experience may indicate that treatment with the CyberKnife System does not improve patient survival or outcomes. Likewise, because the TomoTherapy Systems have only been on the market since 2003, we have limited complication or patient survival rate data with respect to treatment using the system. In addition, while the effectiveness of radiation therapy is well understood, there is a growing but still limited number of peer-reviewed medical journal publications regarding the efficacy of highly conformal treatment such as that delivered by the TomoTherapy System. If future patient studies or clinical experience do not support our beliefs that the TomoTherapy System offers a more advantageous treatment for a wide variety of cancer types, use of the system could fail to increase or could decrease, and our business would therefore be adversely affected. 38 Such results could reduce the rate of reimbursement by both public and private third-party payors for procedures that are performed with our products, slow the adoption of our products by physicians, significantly reduce our ability to achieve expected revenues and could prevent us from becoming profitable. In addition, if future results and experience indicate that our products cause unexpected or serious complications or other unforeseen negative effects, the FDA could rescind our clearances, our reputation with physicians, patients and others may suffer and we could be subject to significant legal liability. We rely on third parties to perform spare parts shipping and other logistics functions on our behalf. A failure or disruption at our logistics providers would adversely impact our business. Customer service is a critical element of our sales strategy. Third-party logistics providers store most of our spare parts inventory in depots around the world and perform a significant portion of our spare parts logistics and shipping activities. If any of our logistics providers terminates its relationship with us, suffers an interruption in its business, or experiences delays, disruptions or quality control problems in its operations, or we have to change and qualify alternative logistics providers for our spare parts, shipments of spare parts to our customers may be delayed and our reputation, business, financial condition and results of operations may be adversely affected. Third- parties may claim we are infringing their intellectual property, and we could suffer significant litigation or licensing expenses or be prevented from selling our product. The medical device industry is characterized by a substantial amount of litigation over patent and other intellectual property rights. In particular, the field of radiation treatment of cancer is well established and crowded with the intellectual property of competitors and others. We also expect that other participants will enter the field. A number of companies in our market, as well as universities and research institutions, have issued patents and have filed patent applications which relate to the use of radiation therapy and stereotactic radiosurgery to treat cancerous and benign tumors. Determining whether a product infringes a patent involves complex legal and factual issues, and the outcome of patent litigation actions is often uncertain. We have not conducted an extensive search of patents issued to third parties, and no assurance can be given that third-party patents containing claims covering our products, parts of our products, technology or methods do not exist, have not been filed, or could not be filed or issued. Because of the number of patents issued and patent applications filed in our technical areas or fields, our competitors or other third parties may assert that our products and the methods we employ in the use of our products are covered by United States or foreign patents held by them. In addition, because patent applications can take many years to issue and because publication schedules for pending applications vary by jurisdiction, there may be applications now pending of which we are unaware, and which may result in issued patents which our current or future products infringe. Also, because the claims of published patent applications can change between publication and patent grant, there may be published patent applications that may ultimately issue with claims that we infringe. There could also be existing patents that one or more of our products or parts may infringe and of which we are unaware. As the number of competitors in the market for less invasive cancer treatment alternatives grows, and as the number of patents issued in this area grows, the possibility of patent infringement claims against us increases. Regardless of the merit of infringement claims, they can be time-consuming, result in costly litigation and diversion of technical and management personnel. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise funds, if necessary, to continue our operations. 39 In the event that we become subject to a patent infringement or other intellectual property lawsuit and if the relevant patents or other intellectual property were upheld as valid and enforceable and we were found to infringe or violate the terms of a license to which we are a party, we could be prevented from selling our products unless we could obtain a license or were able to redesign the product to avoid infringement. Required licenses may not be made available to us on acceptable terms or at all. If we were unable to obtain a license or successfully redesign our system, we might be prevented from selling our system. If there is an allegation or determination that we have infringed the intellectual property rights of a competitor or other person, we may be required to pay damages, pay ongoing royalties or otherwise settle such matter upon terms that are unfavorable to us. In these circumstances, we may be unable to sell our products at competitive prices or at all, and our business and operating results could be harmed. We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers. As is common in the medical device industry, we employ individuals who were previously employed at other medical equipment or biotechnology companies, including our competitors or potential competitors. We may be subject to claims that we or those employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against claims of this nature, litigation could result in substantial costs and be a distraction to management. It is difficult and costly to protect our intellectual property and our proprietary technologies, and we may not be able to ensure their protection. Our success depends significantly on our ability to obtain, maintain and protect our proprietary rights to the technologies used in our products. Patents and other proprietary rights provide uncertain protections, and we may be unable to protect our intellectual property. For example, we may be unsuccessful in defending our patents and other proprietary rights against third-party challenges. As key patents expire, our ability to prevent competitors from copying our technology may be limited. In addition to patents, we rely on a combination of trade secrets, copyright and trademark laws, nondisclosure agreements and other contractual provisions and technical security measures to protect our intellectual property rights. These measures may not be adequate to safeguard the technology underlying our products. If these measures do not protect our rights adequately, third parties could use our technology, and our ability to compete in the market would be reduced. Although we have attempted to obtain patent coverage for our technology where available and appropriate, there are aspects of the technology for which patent coverage was never sought or never received. There are also countries in which we sell or intend to sell the CyberKnife or TomoTherapy Systems but have no patents or pending patent applications. Our ability to prevent others from making or selling duplicate or similar technologies will be impaired in those countries in which we have no patent protection. Although we have several issued patents in the United States and in foreign countries protecting aspects of the CyberKnife and TomoTherapy Systems, our pending United States and foreign patent applications may not issue, may issue only with limited coverage or may issue and be subsequently successfully challenged by others and held invalid or unenforceable. Similarly, our issued patents and those of our licensors may not provide us with any competitive advantages. Competitors may be able to design around our patents or develop products which provide outcomes comparable or superior to ours. Our patents may be held invalid or unenforceable as a result of legal challenges by third parties, and others may challenge the inventorship or ownership of our patents and pending patent applications. In addition, the laws of some foreign countries may not protect our intellectual property rights to the same extent as do the laws of the United States. In the event a competitor infringes upon our patent or other intellectual property rights, enforcing those rights 40 may be difficult and time consuming. Even if successful, litigation to enforce our intellectual property rights or to defend our patents against challenge could be expensive and time consuming and could divert our management’s attention from our core business. We may not have sufficient resources to enforce our intellectual property rights or to defend our patents against a challenge. In addition, we may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially valuable. Litigation also puts our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing. Additionally, we may provoke third parties to assert claims against us. We also license patent and other proprietary rights to aspects of our technology to third parties in fields where we currently do not operate as well as in fields where we currently do operate. Disputes with our licensees may arise regarding the scope and content of these licenses. Further, our ability to expand into additional fields with our technologies may be restricted by our existing licenses or licenses we may grant to third parties in the future. The policies we have in place to protect our trade secrets may not be effective in preventing misappropriation of our trade secrets by others. In addition, confidentiality agreements executed by our employees, consultants and advisors may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure. Litigating a trade secret claim is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge methods and know-how. If we are unable to protect our intellectual property rights, we may be unable to prevent competitors from using our own inventions and intellectual property to compete against us and our business may be harmed. Unfavorable results of legal proceedings could materially and adversely affect our financial condition. We are and may become a party to legal proceedings, claims and other legal matters in the ordinary course of business or otherwise. These legal proceedings, claims and other legal matters, regardless of merit, may be costly, time-consuming and require the attention of key management and other personnel. The outcomes of such matters are uncertain and difficult to predict. If any such matters are adjudicated against us, in whole or in part, we may be subject to substantial monetary damages, disgorgement of profits, and injunctions that prevent us from operating our business, any of which could materially and adversely affect our business and financial condition. We cannot guarantee that our insurance coverage will be sufficient to cover any damages awarded against us. If we are not able to meet the requirements of our license agreement with the Wisconsin Alumni Research Foundation, or WARF, we could lose access to the technologies licensed thereunder and be unable to manufacture, market or sell the TomoTherapy Systems. We license patents from WARF covering the multi-leaf collimator and other key technologies incorporated into the TomoTherapy Systems under a license agreement that requires us to pay royalties to WARF. In addition, the license agreement obligates us to pursue an agreed development plan and to submit periodic reports, and restricts our ability to take actions to defend the licensed patents. WARF has the right to unilaterally terminate the agreement if we do not meet certain minimum royalty obligations or satisfy other obligations related to our utilization of the technology. If WARF were to terminate the agreement or if we were to otherwise lose the ability to exploit the licensed patents, our competitive advantage would be reduced and we may not be able to find a source to replace the licensed technology. The license agreement reserves to WARF the initial right to defend or prosecute any claim arising with respect to the licensed technology. If WARF does not vigorously defend the patents, we may be required to engage in expensive patent litigation to enforce our rights, and any competitive advantage we have based on the licensed technology may be hampered. Any of these events could adversely affect our business, financial condition and results of operations. 41 International sales of our products account for a significant portion of our revenue, which exposes us to risks inherent in international operations. Our international sales, as a percentage of total revenue, have increased over the last five fiscal years. The percentage of our revenue derived from sales outside of the Americas region was 54% in 2015, 58% in 2014 and 55% in 2013. To accommodate our international sales, we have invested significant financial and management resources to develop an international infrastructure that will meet the needs of our customers. We anticipate that a significant portion of our revenue will continue to be derived from sales of our products in foreign markets and that the percentage of our overall revenue that is derived from these markets may continue to increase. This revenue and related operations will therefore continue to be subject to the risks associated with international operations, including: (cid:129) economic or political instability in foreign countries; (cid:129) import delays; (cid:129) changes in foreign regulatory laws governing, among other matters, the clearance, approval and sales of medical devices; (cid:129) the potential failure to comply with foreign regulatory requirements to sell and market our products; (cid:129) longer payment cycles associated with many customers outside the United States; (cid:129) adequate coverage and reimbursement for the CyberKnife and TomoTherapy treatment procedures outside the United States; (cid:129) failure of local laws to provide the same degree of protection against infringement of our intellectual property; (cid:129) protectionist laws and business practices that favor local competitors; (cid:129) the possibility that foreign countries may impose additional taxes, tariffs or other restrictions on foreign trade; (cid:129) risks relating to foreign currency, including fluctuations in foreign currency exchange rates possibly causing fewer sales due to the strengthening of the U.S. Dollar; and (cid:129) contractual provisions governed by foreign laws and various trade restrictions, including U.S. prohibitions and restrictions on exports of certain products and technologies to certain nations. Our inability to overcome these obstacles could harm our business, financial condition and operating results. Even if we are successful in managing these obstacles, our partners internationally are subject to these same risks and may not be able to manage these obstacles effectively. In addition, future imposition of, or significant increases in, the level of customs duties, export quotas, regulatory restrictions or trade restrictions could materially harm our business. We face risks related to the current global economic environment, which could delay or prevent our customers from obtaining financing to purchase the CyberKnife and TomoTherapy Systems and implement the required facilities, which would adversely affect our business, financial condition and results of operations. The state of the global economy continues to be uncertain. The current global economic conditions and uncertain credit markets and concerns regarding the availability of credit pose a risk that could impact consumer and customer demand for our products, as well as our ability to manage normal commercial relationships with our customers, suppliers and creditors, including financial institutions. If the current situation continues to deteriorate or does not improve, our business could be negatively 42 affected, including by reduced demand for our products resulting from a slow-down in the general economy, supplier or customer disruptions and/or temporary interruptions in our ability to conduct day-to-day transactions through our financial intermediaries involving the payment to or collection of funds from our customers, vendors and suppliers. For example, in the United States, some of our customers have been delayed in obtaining, or have not been able to obtain, necessary financing for their purchases of the CyberKnife or TomoTherapy Systems. In addition, some of our customers have been delayed in obtaining, or have not been able to obtain, necessary financing for the construction or renovation of facilities to house CyberKnife or TomoTherapy Systems, the cost of which can be substantial. These delays have in some instances led to our customers postponing the shipment and installation of previously ordered systems or cancelling their system orders, and may cause other customers to postpone their system installation or to cancel their agreements with us. An increase in delays and order cancellations of this nature would adversely affect our product sales, backlog and revenues, and therefore harm our business and results of operations. Because the majority of our product revenue is derived from sales of the CyberKnife and TomoTherapy Systems, and because we experience a long and variable sales and installation cycle, our quarterly results may be inconsistent from period to period. Our primary products are the CyberKnife and TomoTherapy Systems. We expect to generate substantially all of our revenue for the foreseeable future from sales of and service contracts for the CyberKnife and TomoTherapy Systems. The CyberKnife and TomoTherapy Systems have lengthy sales and purchase order cycles because they are major capital equipment items and require the approval of senior management at purchasing institutions. Selling our systems, from first contact with a potential customer to a complete order, generally spans six months to two years and involves personnel with multiple skills. The sales process in the United States typically begins with pre-selling activity followed by sales presentations and other sales related activities. After the customer has expressed an intention to purchase a CyberKnife or TomoTherapy System, we negotiate and enter into a definitive purchase contract with the customer. The negotiation of terms that are not standard for Accuray may require additional time and approvals. Typically, following the execution of the contract, the customer begins the building or renovation of a radiation-shielded facility to house the CyberKnife or TomoTherapy System, which together with the subsequent installation of the CyberKnife or TomoTherapy System, can take up to 24 months to complete. In order to construct this facility, the customer must typically obtain radiation device installation permits, which are granted by state and local government bodies, each of which may have different criteria for permit issuance. If a permit was denied for installation at a specific hospital or treatment center, our CyberKnife or TomoTherapy System could not be installed at that location. In addition, some of our customers are cancer centers or facilities that are new, and in these cases it may be necessary for the entire facility to be completed before the CyberKnife or TomoTherapy System can be installed, which can result in additional construction and installation delays. Our sales and installations of CyberKnife and TomoTherapy Systems tend to be heaviest during the third month of each fiscal quarter. Under our revenue recognition policy, we generally do not recognize revenue attributable to a CyberKnife or TomoTherapy System purchase until after installation has occurred, if we are responsible for providing installation, or delivery. For international sales through distributors, we typically recognize revenue when the system is shipped and we have evidence of a purchase commitment from the end user. Under our current forms of purchase and service contracts, we record a majority of the purchase price as revenue for a CyberKnife or TomoTherapy System upon installation or delivery of the system. Events beyond our control may delay installation and the satisfaction of contingencies required to receive cash inflows and recognize revenue, including delays in the customer obtaining funding or 43 financing, delays in construction at the customer site or delays in the customer obtaining receipt of regulatory approvals such as certificates of need. The long sales cycle, together with delays in the shipment and installation of CyberKnife and TomoTherapy Systems or customer cancellations, could adversely affect our cash flows and revenue, which would harm our results of operations and may result in significant fluctuations in our reporting of quarterly revenues. Because of these fluctuations, it is likely that in some future quarters, our operating results will fall below the expectations of securities analysts or investors. If that happens, the market price of our stock would likely decrease. These fluctuations also mean that you will not be able to rely upon our operating results in any particular period as an indication of future performance. We depend on third-party distributors to market and distribute our products in international markets. If our distributors fail to successfully market and distribute our products, our business will be materially harmed. We depend on a number of distributors in our international markets. We cannot control the efforts and resources our third-party distributors will devote to marketing the CyberKnife or TomoTherapy Systems. Our distributors may not be able to successfully market and sell the CyberKnife or TomoTherapy Systems, may not devote sufficient time and resources to support the marketing and selling efforts and may not market the CyberKnife or TomoTherapy Systems at prices that will permit the product to develop, achieve or sustain market acceptance. In some jurisdictions, we rely on our distributors to manage the regulatory process, and we are dependent on their ability to do so effectively. In addition, if a distributor is terminated by us or goes out of business, it may take us a period of time to locate an alternative distributor, to seek appropriate regulatory approvals and to train its personnel to market the CyberKnife or TomoTherapy Systems, and our ability to sell and service the CyberKnife or TomoTherapy Systems in the region formerly serviced by such terminated distributor could be materially and adversely affected. Any of these factors could materially and adversely affect our revenue from international markets, increase our costs in those markets or damage our reputation. If we are unable to attract additional international distributors, our international revenue may not grow. If our distributors experience difficulties, do not actively market the CyberKnife or TomoTherapy Systems or do not otherwise perform under our distribution agreements, our potential for revenue and gross margins from international markets may be dramatically reduced, and our business could be harmed. The high unit price of the CyberKnife and TomoTherapy Systems, as well as other factors, may contribute to substantial fluctuations in our operating results, which could adversely affect our stock price. Because of the high unit price of the CyberKnife and TomoTherapy Systems and the relatively small number of units installed each quarter, each installation of a CyberKnife or TomoTherapy System can represent a significant percentage of our revenue for a particular quarter. Therefore, if we do not install a CyberKnife or TomoTherapy System when anticipated, our operating results will vary significantly from our expectations. This is of particular concern in the current volatile economic environment, where we have had experiences with customers cancelling or postponing orders for our CyberKnife and TomoTherapy Systems and delaying any required build-outs. These fluctuations and other potential fluctuations mean that you should not rely upon our operating results in any particular period as an indication of future performance. In particular, in addition to the other risk factors described above and below, factors which may contribute to these fluctuations include: (cid:129) timing of when we are able to recognize revenue associated with sales of the CyberKnife and TomoTherapy Systems, which varies depending upon the terms of the applicable sales and service contracts; (cid:129) the proportion of revenue attributable to our legacy service plans; (cid:129) timing and level of expenditures associated with new product development activities; 44 (cid:129) regulatory requirements in some states for a certificate of need prior to the installation of a radiation device; (cid:129) delays in shipment due, for example, to unanticipated construction delays at customer locations where our products are to be installed, cancellations by customers, natural disasters or labor disturbances; (cid:129) delays in our manufacturing processes or unexpected manufacturing difficulties; (cid:129) timing of the announcement, introduction and delivery of new products or product upgrades by us and by our competitors; (cid:129) timing and level of expenditures associated with expansion of sales and marketing activities such as trade shows and our overall operations; and (cid:129) fluctuations in our gross margins and the factors that contribute to such fluctuations, as described in the Management’s Discussion and Analysis of Financial Condition and Results of Operations. These factors are difficult to forecast and may contribute to substantial fluctuations in our quarterly revenues and substantial variation from our projections, particularly during the periods in which our sales volume is low. These fluctuations may cause volatility in our stock price. As a strategy to assist our sales efforts, we may offer extended payment terms, which may potentially result in higher Days Sales Outstanding and greater payment defaults. We offer longer or extended payment terms for qualified customers in some circumstances. As of June 30, 2015, customer contracts with extended payment terms of more than one year amounted to less than 5% of our accounts receivable balance. While we qualify customers to whom we offer longer or extended payment terms, their financial positions may change adversely over the longer time period given for payment. This may result in an increase in payment defaults, which would affect our revenue, as we recognize revenue on such transactions on a cash basis. Our operations are vulnerable to interruption or loss due to natural disasters, epidemics, terrorist acts and other events beyond our control, which would adversely affect our business. We have facilities in countries around the world, including three manufacturing facilities, each of which is equipped to manufacture unique components of our products. The manufacturing facilities are located in Sunnyvale, California, Madison, Wisconsin and Chengdu, China. We do not maintain backup manufacturing facilities for all of our manufacturing facilities or for our IT facilities, so we depend on each of our current facilities for the continued operation of our business. In addition, we conduct a significant portion of other activities, including administration and data processing, at facilities located in the State of California which has experienced major earthquakes in the past, as well as other natural disasters. Chengdu, China, where one of our manufacturing facilities is located, has also experienced major earthquakes in the past. We do not carry earthquake insurance. Unexpected events at any of our facilities, including fires or explosions; natural disasters, such as hurricanes, floods, tornados and earthquakes; war or terrorist activities; unplanned outages; supply disruptions; and failures of equipment or systems, or the failure to take adequate steps to mitigate the likelihood or potential impact of such events, could significantly disrupt our operations, delay or prevent product manufacture and shipment for the time required to repair, rebuild or replace our manufacturing facilities, which could be lengthy, result in large expenses to repair or replace the facilities, and adversely affect our results of operation. 45 We may attempt to acquire new businesses, products or technologies, or enter into strategic collaborations or alliances, and if we are unable to successfully complete these acquisitions or to integrate acquired businesses, products, technologies or employees, we may fail to realize expected benefits or harm our existing business. Our success will depend, in part, on our ability to expand our product offerings and grow our business in response to changing technologies, customer demands and competitive pressures. In some circumstances, we may determine to do so through the acquisition of complementary businesses, products or technologies, or through collaborating with complementary businesses, rather than through internal development. The identification of suitable acquisition or alliance candidates can be difficult, time consuming and costly, and we may not be able to successfully complete identified acquisitions or alliances. Other companies may compete with us for these strategic opportunities. In addition, even if we successfully complete an acquisition or alliance, we may not be able to successfully integrate newly acquired organizations, products or technologies into our operations, and the process of integration could be expensive, time consuming and may strain our resources, and we may not realize the expected benefits of any acquisition, collaboration or strategic alliance. Furthermore, the products and technologies that we acquire or with respect to which we collaborate may not be successful, or may require significantly greater resources and investments than we originally anticipated. In addition, we may be unable to retain employees of acquired companies, or retain the acquired company’s customers, suppliers, distributors or other partners who are our competitors or who have close relationships with our competitors. Consequently, we may not achieve anticipated benefits of the acquisitions or alliances which could harm our existing business. In addition, future acquisitions or alliances could result in potentially dilutive issuances of equity securities or the incurrence of debt, contingent liabilities or expenses, or other charges such as in-process research and development, any of which could harm our business and affect our financial results or cause a reduction in the price of our common stock. Multiple factors may adversely affect our ability to fully utilize certain tax loss carryforwards. As of June 30, 2015, we had approximately $329.6 million and $157.5 million in federal and state net operating loss carry forwards, respectively, which expire in varying amounts beginning in 2019 for federal and 2016 for state purposes. In addition, as of June 30, 2015, we had federal and state research and development tax credit carryforwards of approximately $16.3 million and $16.5 million, respectively. The federal research credits will begin to expire in 2019, the California research credits have no expiration date, and the other state research credits will begin to expire in 2016. Utilization of our net operating loss and credit carry forwards is subject to annual limitation due to the application of the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions to us. However, none of the federal and state net operating loss carryforwards are expected to expire as a result of the ownership change limitation. Our results may be impacted by changes in foreign currency exchange rates. Currently, the majority of our international sales are denominated in U.S. Dollars. As a result, an increase in the value of the U.S. Dollar relative to foreign currencies could require us to reduce our sales price or make our products less competitive in international markets. We believe the strengthening of the U.S. Dollar has caused a potential delay in orders and we may continue to see our sales decline due to the strengthening of the U.S. Dollar. Also, if our international sales increase, we may enter into a greater number of transactions denominated in non-U.S. Dollars, which would expose us to foreign currency risks, including changes in currency exchange rates. If we are unable to address these risks and challenges effectively, our international operations may not be successful and our business would be materially harmed. 46 Changes in interpretation or application of generally accepted accounting principles may adversely affect our operating results. We prepare our financial statements to conform to United States Generally Accepted Accounting Principles. These principles are subject to interpretation by the Financial Accounting Standards Board, American Institute of Certified Public Accountants, the Public Company Accounting Oversight Board, the Securities and Exchange Commission and various other regulatory or accounting bodies. A change in interpretations of, or our application of, these principles can have a significant effect on our reported results and may even affect our reporting of transactions completed before a change is announced. Additionally, as we are required to adopt new accounting standards, our methods of accounting for certain items may change, which could cause our results of operations to fluctuate from period to period. For example, due to the significance of the software component in certain of our products, we are currently bound by the software revenue recognition rules for a portion of our business. Our liquidity could be adversely impacted by adverse conditions in the financial markets. At June 30, 2015, we had $79.6 million in cash and cash equivalents and $64.3 million in investments. The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of cash in our operating accounts and cash invested in money market funds. The investments are managed by third-party financial institutions and primarily consist of U.S. agency and corporate debt securities. To date, we have experienced no material realized losses on or lack of access to our invested cash, cash equivalents or investments; however, we can provide no assurances that access to our invested cash and cash equivalents will not be impacted by adverse conditions in the financial markets. At any point in time, we also have funds in our operating accounts that are with third-party financial institutions that exceed the Federal Deposit Insurance Corporation, or FDIC, insurance limits. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or become subject to other adverse conditions in the financial markets. To date, we have experienced no loss or lack of access to cash in our operating accounts. Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us from executing our growth strategy. While we believe that our existing cash, cash equivalents and investments will be sufficient to meet our anticipated cash needs for at least the next twelve months, the timing and amount of our working capital and capital expenditure requirements may vary significantly depending on numerous factors, including the other risk factors described above and below. If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity securities or debt securities or obtain other debt financing, which could be difficult or impossible in the current economic and capital markets environments. Our debt levels may impair our ability to obtain additional financing in the future. The sale of additional equity securities or convertible debt securities would result in additional dilution to our stockholders. We cannot assure that additional financing, if required, will be available in amounts or on terms acceptable to us, if at all. 47 Risks Related to the Regulation of our Products and Business Modifications, upgrades and future products related to the CyberKnife or TomoTherapy Systems or new indications may require new FDA 510(k) clearances or premarket approvals, and such modifications, or any defects in design, manufacture or labeling may require us to recall or cease marketing the CyberKnife or TomoTherapy Systems until approvals or clearances are obtained. The CyberKnife and TomoTherapy Systems are medical devices that are subject to extensive regulation in the United States by local, state and the federal government, including by the FDA. The FDA regulates virtually all aspects of a medical device’s design, development, testing manufacturing, labeling, storage, record keeping, adverse event reporting, sale, promotion, distribution and shipping. Before a new medical device, or a new intended use or indication of or claim for an existing product, can be marketed in the United States, it must first receive either premarket approval or 510(k) clearance from the FDA, unless an exemption exists. Either process can be expensive, lengthy and unpredictable. The FDA’s 510(k) clearance process generally takes from three to twelve months, but it can last longer. The process of obtaining premarket approval is much more costly and uncertain than the 510(k) clearance process and it generally takes from one to three years, or even longer, from the time the application is filed with the FDA. Despite the time, effort and cost, there can be no assurance that a particular device or a modification of a device will be approved or cleared by the FDA in a timely fashion, if at all. Even if we are granted regulatory clearances or approvals, they may include significant limitations on the indicated uses of the product, which may limit the market for those products, and how those products can be promoted. Medical devices may be marketed only for the indications for which they are approved or cleared. The FDA also may change its policies, adopt additional regulations, or revise existing regulations, each of which could prevent or delay premarket approval or 510(k) clearance of our device, or could impact our ability to market our currently cleared device. We are also subject to medical device reporting regulations which require us to report to the FDA if our products cause or contribute to a death or a serious injury, or malfunction in a way that would likely cause or contribute to a death or a serious injury. We also are subject to Quality System regulations. Our products are also subject to state regulations and various worldwide laws and regulations. A component of our strategy is to continue to upgrade the CyberKnife and TomoTherapy Systems. Upgrades previously released by us required 510(k) clearance before we were able to offer them for sale. We expect our future upgrades will similarly require 510(k) clearance; however, future upgrades may be subject to the substantially more time consuming data generation requirements and uncertain premarket approval or clearance process. If we were required to use the premarket approval process for future products or product modifications, it could delay or prevent release of the proposed products or modifications, which could harm our business. The FDA requires device manufacturers to make their own determination of whether or not a modification requires an approval or clearance; however, the FDA can review a manufacturer’s decision not to submit for additional approvals or clearances. Any modification to an FDA approved or cleared device that would significantly affect its safety or efficacy or that would constitute a major change in its intended use would require a new premarket approval or 510(k) clearance. The FDA has recently issued a draft guidance that, if finalized, will result in manufacturers needing to seek a significant number of new or additional clearances for changes made to legally marketed devices. We cannot assure you that the FDA will agree with our decisions not to seek approvals or clearances for particular device modifications or that we will be successful in obtaining premarket approvals or 510(k) clearances for modifications in a timely fashion, if at all. We have obtained 510(k) clearance for the CyberKnife Systems for the treatment of tumors anywhere in the body where radiation is indicated, and we have obtained 510(k) clearance for the TomoTherapy Systems to be used as integrated systems for the planning and delivery of IMRT for the 48 treatment of cancer. We have made modifications to the CyberKnife and TomoTherapy Systems in the past and may make additional modifications in the future that we believe do not or will not require additional approvals or clearances. If the FDA disagrees, based on new finalized guidance and requires us to obtain additional premarket approvals or 510(k) clearances for any modifications to the CyberKnife or TomoTherapy Systems and we fail to obtain such approvals or clearances or fail to secure approvals or clearances in a timely manner, we may be required to cease manufacturing and marketing the modified device or to recall such modified device until we obtain FDA approval or clearance and we may be subject to significant regulatory fines or penalties. The FDA and similar governmental authorities in other countries in which we market and sell our products have the authority to require the recall of our products in the event of material deficiencies or defects in design, manufacture or labeling. A government mandated recall, or a voluntary recall by us, could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling and user manuals. Any recall could divert management’s attention, cause us to incur significant expenses, generate negative publicity, harm our reputation with customers, negatively affect our future sales and business, require redesign of the CyberKnife or TomoTherapy Systems, and harm our operating results. In these circumstances, we may also be subject to significant enforcement action. If any of these events were to occur, our ability to introduce new or enhanced products in a timely manner would be adversely affected, which in turn would harm our future growth. We are subject to federal, state and foreign laws applicable to our business practices, the violation of which could result in substantial penalties and harm our business. Laws and ethical rules governing interactions with healthcare providers. The Medicare and Medicaid ‘‘anti-kickback’’ laws, and similar state laws, prohibit soliciting, offering, paying or accepting any payments or other remuneration that is intended to induce any individual or entity to either refer patients to or purchase, lease or order, or arrange for or recommend the purchase, lease or order of, healthcare products or services for which payment may be made under federal and state healthcare programs, such as Medicare and Medicaid. Such laws impact our sales, marketing and other promotional activities by reducing the types of financial arrangements we may have with our customers, potential customers, marketing consultants and other service providers. They particularly impact how we structure our sales offerings, including discount practices, customer support, product loans, education and training programs, physician consulting, research grants and other service arrangements. Many of these laws are broadly drafted and are open to a variety of interpretations, making it difficult to determine with any certainty whether certain arrangements violate such laws, even if statutory safe harbors are available. In addition to such anti-kickback laws, federal and state ‘‘false claims’’ laws generally prohibit the knowing filing or causing the filing of a false claim or the knowing use of false statements to obtain payment from government payors. Although we do not submit claims directly to payors, manufacturers can be held liable under these laws if they are deemed to ‘‘cause’’ the submission of false or fraudulent claims by providing inaccurate billing or coding information to customers, or through certain other activities, including promoting products for uses or indications that are not approved by the FDA. We are also subject to federal and state physician self-referral laws. The federal Ethics in Patient Referrals Act of 1989, commonly known as the Stark Law, prohibits, subject to certain exceptions, physician referrals of Medicare and Medicaid patients to an entity providing certain ‘‘designated health services’’ if the physician or an immediate family member has any financial relationship with the entity. The Stark Law also prohibits the entity receiving the referral from billing any good or service furnished pursuant to an unlawful referral. Various states have corollary laws to the Stark Law, including laws that require physicians to disclose any financial interest they may have with a healthcare provider to their patients when referring patients to that provider. Both the scope and exceptions for such laws vary from state to state. 49 If our past or present operations are found to be in violation of any of these ‘‘anti-kickback,’’ ‘‘false claims,’’ ‘‘self-referral’’ or other similar laws in foreign jurisdictions, we may be subject to the applicable penalty associated with the violation, which may include significant civil and criminal penalties, damages, fines, imprisonment and exclusion from healthcare programs. The impact of any such violations may lead to curtailment or restructuring of our operations, which could adversely affect our ability to operate our business and our financial results. Anti-corruption laws. We are also subject to laws regarding the conduct of business overseas, such as the U.S. Foreign Corrupt Practices Act, or FCPA, the U.K. Bribery Act of 2010, the Brazil Clean Companies Act, and other similar laws in foreign countries in which we operate. The FCPA prohibits the provision of illegal or improper inducements to foreign government officials in connection with the obtaining of business overseas. Becoming familiar with and implementing the infrastructure necessary to ensure that we and our distributors comply with such laws, rules and regulations and mitigate and protect against corruption risks could be quite costly, and there can be no assurance that any policies and procedures we do implement will protect us against liability under the FCPA or related laws for actions taken by our employees, executive officers, distributors, agents and other intermediaries with respect to our business. Violations of the FCPA or other similar laws by us or any of our employees, executive officers, distributors, agents or other intermediaries could subject us or the individuals involved to criminal or civil liability, cause a loss of reputation in the market, and materially harm our business. Laws protecting patient health information. There are a number of federal and state laws protecting the confidentiality of certain patient health information, including patient records, and restricting the use and disclosure of that protected information. In particular, the U.S. Department of Health and Human Services, or HHS, has promulgated patient privacy rules under the Health Insurance Portability and Accountability Act of 1996, or HIPAA. These privacy rules protect medical records and other personal health information of patients by limiting their use and disclosure, giving patients the right to access, amend and seek accounting of their own health information and limiting most uses and disclosures of health information to the minimum amount reasonably necessary to accomplish the intended purpose. The HIPAA privacy standard was amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, enacted as part of the American Recovery and Reinvestment Act of 2009. Although we are not a ‘‘covered entity’’ under HIPAA, we are considered a ‘‘business associate’’ of certain covered entities and, as such, we are directly subject to HIPAA, including its enforcement scheme and inspection requirements, and are required to implement policies, procedures as well as reasonable and appropriate physical, technical and administrative security measures to protect individually identifiable health information we receive from covered entities. Our failure to protect health information received from customers in compliance with HIPAA or other laws could subject us to civil and criminal liability to the government and civil liability to the covered entity, could result in adverse publicity, and could harm our business and impair our ability to attract new customers. Transparency laws. The Physician Payment Sunshine Act, or the Sunshine Act, which was enacted by Congress as part of the Patient Protection and Affordable Care Act on December 14, 2011, requires each applicable manufacturer, which includes medical device companies such as Accuray, to track and report to the federal government on an annual basis all payments and other transfers of value from such applicable manufacturer to U.S. licensed physicians and teaching hospitals as well as physician ownership of such applicable manufacturer’s equity, in each case subject to certain statutory exceptions. Such data will be made available by the government on a publicly searchable website. Failure to comply with the data collection and reporting obligations imposed by the Sunshine Act can result in civil monetary penalties ranging from $1,000 to $10,000 for each payment or other transfer of value that is not reported (up to a maximum of $150,000 per reporting period) and from $10,000 to $100,000 for each knowing failure to report (up to a maximum of $1 million per reporting period). In addition, we 50 are subject to similar state and foreign laws related to the tracking and reporting of payments and other transfers of value to healthcare professionals, the violation of which could, among other things, result in civil monetary penalties and adversely impact our reputation and business. Conflict Minerals. The Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules promulgated by the SEC under such act require companies, including Accuray, to disclose the existence in their products of certain metals, including tantalum, tin, gold, tungsten and their derivatives, that originate from the Democratic Republic of the Congo and adjoining countries. Under these rules, we are required to obtain sourcing data from suppliers, perform supply chain due diligence, and file annually with the SEC a specialized disclosure report on Form SD covering the prior calendar year. These requirements could adversely affect the sourcing, availability, and pricing of minerals used in the manufacture of components used in our products. We may also encounter customers who require that all of the components of our products be certified as conflict free. If we are not able to meet this requirement, such customers may choose not to purchase our products, which could adversely impact sales of our products, and impact our results of operation. In addition, we have incurred and expect to incur additional costs to comply with these disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. If we or our distributors do not obtain and maintain the necessary regulatory approvals in a specific country, we will not be able to market and sell our products in that country. To be able to market and sell our products in a specific country, we or our distributors must comply with applicable laws and regulations of that country. In jurisdictions where we rely on our distributors to manage the regulatory process, we are dependent on their ability to do so effectively. While the laws and regulations of some countries do not impose barriers to marketing and selling our products or only require notification, others require that we or our distributors obtain the approval of a specified regulatory body. These laws and regulations, including the requirements for approvals, and the time required for regulatory review vary from country to country. The governmental agencies regulating medical devices in some countries, for example, require that the user interface on medical device software be in the local language. We currently provide user guides and manuals, both paper copies and electronically, in the local language but only provide an English language version of the user interface. Obtaining regulatory approvals is expensive and time-consuming, and we cannot be certain that we or our distributors will receive regulatory approvals in each country in which we market or plan to market our products. If we modify our products, we or our distributors may need to apply for additional regulatory approvals before we are permitted to sell them. We may not continue to meet the quality and safety standards required to maintain the authorizations that we or our distributors have received. It can also be costly for us and our distributors to keep up with regulatory changes issued or mandated from time to time. If we change distributors, it may be time-consuming and disruptive to our business to transfer the required regulatory approvals, particularly if such approvals are maintained by our third-party distributors on our behalf. If we or our distributors are unable to maintain our authorizations, or fail to obtain appropriate authorizations in a particular country, we will no longer be able to sell our products in that country, and our ability to generate revenue will be materially adversely affected. Within the European Union, we are required under the Medical Device Directive to affix the Conformit´e Europ´eene, or CE, mark on our products in order to sell the products in member countries of the EU. This conformity to the applicable directives is done through self declaration and is verified by an independent certification body, called a Notified Body, before the CE mark can be placed on the device. Once the CE mark is affixed to the device, the Notified Body will regularly audit us to ensure that we remain in compliance with the applicable European laws or directives. CE marking demonstrates that our products comply with the laws and regulations required by the European Union countries to allow free movement of trade within those countries. If we cannot support our 51 performance claims and/or demonstrate or maintain compliance with the applicable European laws and directives, we lose our CE mark, which would prevent us from selling our products within the European Union. Under the Pharmaceutical Affairs Law in Japan, a pre-market approval necessary to sell, market and import a product, or Shonin, must be obtained from the Ministry of Health, Labor and Welfare, or MHLW, for our products. Before issuing approvals, MHLW examines the application in detail with regard to the quality, efficacy, and safety of the proposed medical device. The Shonin is granted once MHLW is content with the safety and effectiveness of the medical device. The time required for approval varies. A delay in approval could prevent us from selling our products in Japan, which could impact our ability to generate revenue and harm our business. In addition to laws and regulations regarding medical devices, we are subject to a variety of environmental laws and regulations regulating our operations, including those relating to the use, generation, handling, storage, transportation, treatment and disposal of hazardous materials, which laws impose compliance costs on our business and can also result in liability to us. For example, the recast Directive on Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, or the RoHS Directive, which began applying to medical devices in July 2014, bans placing new electrical and electronic equipment on the EU market containing more than certain specified levels of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl or PBB and polybrominated diphenyl ether. We believe that the RoHS Directive does not impose any restrictions on our products because our products are exempt as large scale fixed installations. The Notified Body which audits our compliance efforts has indicated that they share our view in this respect and that we are and will remain in compliance with the RoHS Directive because the RoHS Directive’s restrictions do not apply to our products. Nevertheless, there can be no guarantee that the EU will not challenge such determination and, accordingly, we intend to comply with the RoHS restrictions, whether or not they apply, and are in the process of updating the way our products are built with a view toward achieving such compliance gradually over time. Healthcare reform legislation could adversely affect demand for our products, our revenue and our financial condition. In March 2010, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 were signed into law. The Affordable Care Act provides for, among other things, a 2.3% excise tax on U.S. sales of medical devices, including our products, effective as of 2013. This tax burden may have a material, negative impact on our business, results of operations and cash flow. In addition, these two pieces of legislation include a large number of other health related provisions, including expanding Medicaid eligibility, requiring most individuals to have health insurance, establishing new regulations on health plans, establishing health insurance exchanges, requiring manufacturers to report payments or other transfers of value made to physicians and teaching hospitals, modifying certain payment systems to encourage more cost-effective care and a reduction of inefficiencies and waste and including new tools to address fraud and abuse. The laws also include a decrease in the annual rate of inflation for Medicare payments to hospitals and the establishment of an independent payment advisory board to suggest methods of reducing the rate of growth in Medicare spending. There continue to be many programs and requirements for which the details have not yet been fully established or consequences not fully understood, and it is unclear what the full impact of the legislation will be. In addition, since the adoption of the Affordable Care Act, other legislation designed to keep federal healthcare costs down has been proposed or passed. For example, under the sequestration required by the Budget Control Act of 2011, as amended by the American Taxpayer Relief Act of 2012, Medicare payments for all items and services under Parts A and B incurred on or after April 1, 2013 have been reduced by up to 2%. Future federal legislation may impose further limitations on the 52 coverage or amounts of reimbursement available for our products from governmental agencies or third- party payors. These limitations could have a negative impact on the demand for our products and services, and therefore on our financial position and results of operations. Future legislative or policy initiatives directed at reducing costs could be introduced at either the federal or state level. We cannot predict what healthcare reform legislation or regulations, if any, will be enacted in the United States or elsewhere, what impact any legislation or regulations related to the healthcare system that may be enacted or adopted in the future might have on our business, or the effect of ongoing uncertainty or public perception about these matters will have on the purchasing decisions of our customers. However, the implementation of new legislation and regulation may materially lower reimbursements for our products, materially reduce medical procedure volumes and significantly and adversely affect our business. Risks Related to Our Common Stock Our major stockholders own approximately 43.3% and directors and executive officers own approximately 1.3% of our outstanding common stock as of June 30, 2015, which could limit other stockholders’ ability to influence the outcome of key transactions, including changes of control. As of June 30, 2015, our current holders of 5% or more of our outstanding common stock held in the aggregate approximately 43% of our outstanding common stock, while our directors and executive officers held in the aggregate approximately 1% of our outstanding common stock. This concentration of ownership may delay, deter or prevent a change of control of our company and will make some transactions more difficult or impossible without the support of these stockholders. The price of our common stock is volatile and may continue to fluctuate significantly, which could lead to losses for stockholders. The trading prices of the stock of high-technology companies of our size can experience extreme price and volume fluctuations. These fluctuations often have been unrelated or out of proportion to the operating performance of these companies. Our stock price has experienced periods of volatility. Broad market fluctuations may also harm our stock price. Any negative change in the public’s perception of the prospects of companies that employ similar technology or sell into similar markets could also depress our stock price, regardless of our actual results. In addition to the other risk factors described above and below, factors affecting the trading price of our common stock include: (cid:129) regulatory developments related to manufacturing, marketing or sale of the CyberKnife or TomoTherapy Systems; (cid:129) political or social uncertainties; (cid:129) changes in product pricing policies; (cid:129) variations in our operating results, as well as costs and expenditures; (cid:129) announcements of technological innovations, new services or service enhancements, strategic alliances or significant agreements by us or by our competitors; (cid:129) recruitment or departure of key personnel; (cid:129) changes in earnings estimates by analysts or changes in accounting policies; and (cid:129) market conditions in our industry, the industries of our customers and the economy as a whole. 53 The sale of material amounts of common stock could encourage short sales by third parties and depress the price of our common stock. The downward pressure on our stock price caused by the sale of a significant number of shares of our common stock or the perception that such sales could occur by any of our significant stockholders could cause our stock price to decline, thus allowing short sellers of our stock an opportunity to take advantage of any decrease in the value of our stock. The presence of short sellers in our common stock may further depress the price of our common stock. Future issuances of shares of our common stock could dilute the ownership interests of our stockholders. Any issuance of equity securities could dilute the interests of our stockholders and could substantially decrease the trading price of our common stock. We may issue equity securities in the future for a number of reasons, including to finance our operations and business strategy (including in connection with acquisitions, strategic collaborations or other transactions), to adjust our ratio of debt to equity, to satisfy our obligations upon the exercise of outstanding options or for other reasons. In August 2011, we issued $100 million aggregate principal amount of our 3.75% Convertible Senior Notes due August 1, 2016 (the ‘‘3.75% Convertible Notes’’), and in February 2013, we issued $115 million aggregate principal amount of our 3.50% Convertible Senior Notes due February 1, 2018 (the ‘‘3.50% Convertible Notes’’). In April 2014, we issued approximately $70.3 million aggregate principal amount of our 3.50% Series A Convertible Senior Notes due February 1, 2018 (the ‘‘3.50% Series A Convertible Notes,’’ and collectively with the 3.75% Convertible Notes and the 3.50% Convertible Notes, the ‘‘Convertible Notes’’) and paid approximately $0.4 million in cash to refinance approximately $70.3 million aggregate principal amount of our 3.50% Convertible Notes. Following such transactions, approximately $44.7 million aggregate principal amount of the 3.50% Convertible Notes remained outstanding. To the extent we issue common stock upon conversion of the Convertible Notes, that conversion would dilute the ownership interests of our stockholders. Increased leverage as a result of the Convertible Notes offering may harm our financial condition and operating results. As of June 30, 2015, we had total consolidated long-term liabilities of approximately $224.3 million, including the liability component of the 3.75% Convertible Notes in the amount of $93.7 million, the 3.50% Convertible Notes in the amount of $44.7 million and the 3.50% Series A Convertible Notes of $64.5 million. In April 2014, we refinanced approximately $70.3 million aggregate principal amount of the 3.50% Convertible Notes held by certain investors (the ‘‘Participating Holders’’) with approximately $70.3 million aggregate principal amount of the 3.50% Series A Convertible Notes. In connection with such transactions, we also paid the Participating Holders approximately $0.4 million in cash. Our level of indebtedness could have important consequences to stockholders and note holders, because: (cid:129) it could affect our ability to satisfy our obligations under the Convertible Notes; (cid:129) a substantial portion of our cash flows from operations will have to be dedicated to interest and principal payments and may not be available for operations, working capital, capital expenditures, expansion, acquisitions or general corporate or other purposes; (cid:129) it may impair our ability to obtain additional financing in the future; (cid:129) it may limit our flexibility in planning for, or reacting to, changes in our business and industry; and 54 (cid:129) it may make us more vulnerable to downturns in our business, our industry or the economy in general. The conditional conversion features of the 3.75% Convertible Notes and the 3.50% Series A Convertible Notes, if triggered, may adversely affect our financial condition and operating results. In the event the conditional conversion features of the 3.75% Convertible Notes or the 3.50% Series A Convertible Notes are triggered, holders of the 3.75% Convertible Notes or the 3.50% Series A Convertible Notes, as applicable, will be entitled to convert such notes at any time during specified periods at their option. If one or more holders elect to convert such notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying solely cash in lieu of any fractional share), including if we have irrevocably elected full physical settlement upon conversion, we would be required to make cash payments to satisfy all or a portion of our conversion obligation based on the applicable conversion rate, which could adversely affect our liquidity. In addition, even if holders do not elect to convert such notes, if we have irrevocably elected net share settlement upon conversion we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of such notes as a current rather than long-term liability, which could result in a material reduction of our net working capital. The 3.50% Convertible Notes do not provide for such a conditional conversion feature. Provisions in the indenture for the Convertible Notes, our certificate of incorporation and our bylaws could discourage or prevent a takeover, even if an acquisition would be beneficial in the opinion of our stockholders. Provisions of our certificate of incorporation and bylaws could make it more difficult for a third- party to acquire us, even if doing so would be beneficial in the opinion of our stockholders. These provisions include: (cid:129) authorizing the issuance of ‘‘blank check’’ preferred stock that could be issued by our board of directors to increase the number of outstanding shares and thwart a takeover attempt; (cid:129) establishing a classified board of directors, which could discourage a takeover attempt; (cid:129) prohibiting cumulative voting in the election of directors, which would limit the ability of less than a majority of stockholders to elect director candidates; (cid:129) limiting the ability of stockholders to call special meetings of stockholders; (cid:129) prohibiting stockholder action by written consent and requiring that all stockholder actions be taken at a meeting of our stockholders; and (cid:129) establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings. In addition, Section 203 of the Delaware General Corporation Law may discourage, delay or prevent a change of control of our company. Generally, Section 203 prohibits stockholders who, alone or together with their affiliates and associates, own more than 15% of the subject company from engaging in certain business combinations for a period of three years following the date that the stockholder became an interested stockholder of such subject company without approval of the board or 662⁄3% of the independent stockholders. The existence of these provisions could adversely affect the voting power of holders of common stock and limit the price that investors might be willing to pay in the future for shares of our common stock. Furthermore, if a ‘‘fundamental change’’ (as such terms are defined in each the indentures of the Convertible Notes) occurs, holders of the Convertible Notes will have the right, at their option, to require us to repurchase all or a portion of their Convertible Notes. A ‘‘fundamental change’’ generally 55 occurs when there is a change in control of Accuray (acquisition of 50% or more of our voting stock, liquidation or sale of Accuray not for stock) or trading of our stock is terminated. In the event of a ‘‘make-whole fundamental change’’ (as such term is defined in each of the indentures for the Convertible Notes), we may also be required to increase the conversion rate applicable to the Convertible Notes surrendered for conversion in connection with such make-whole fundamental change. A ‘‘make-whole fundamental change’’ is generally a sale of Accuray not for stock in another publicly traded company. In addition, each of the indentures for the Convertible Notes prohibits us from engaging in certain mergers or acquisitions unless, among other things, the surviving entity assumes our obligations under the Convertible Notes. We have not paid dividends in the past and do not expect to pay dividends in the foreseeable future. We have never declared or paid cash dividends on our capital stock. We currently intend to retain all future earnings for the operation and expansion of our business and, therefore, do not anticipate declaring or paying cash dividends in the foreseeable future. The payment of dividends will be at the discretion of our board of directors and will depend on our results of operations, capital requirements, financial condition, prospects, contractual arrangements, and other factors our board of directors may deem relevant. If we do not pay dividends, a return on a stockholders’ investment will only occur if our stock price appreciates. Item 1B. UNRESOLVED STAFF COMMENTS None. Item 2. PROPERTIES Facilities We currently lease approximately 164,000 square feet of product development, manufacturing and administrative space in three buildings in Sunnyvale, California, as follows: (cid:129) A manufacturing building totaling approximately 50,000 square feet, which is leased to us until December 2018; and (cid:129) Two headquarters buildings that are approximately 74,000 square feet and 40,000 square feet, respectively, which are leased to us until December 2023. We have the right to renew the lease term of our headquarters office buildings for two five-year terms upon prior written notice and the fulfillment of certain conditions. Our wholly owned subsidiary, TomoTherapy leases approximately 153,000 square feet of product development, manufacturing and administrative space in three buildings in Madison, Wisconsin, as follows: (cid:129) An office building totaling approximately 61,000 square feet, which is leased to TomoTherapy until June 2018; (cid:129) A manufacturing facility totaling approximately 56,000 square feet, which is leased to TomoTherapy until April 2018; and (cid:129) A portion of an office building totaling approximately 36,000 square feet, which is leased to TomoTherapy until April 2019. Our wholly owned subsidiary, Accuray International Sarl, leases approximately 9,418 square feet of administrative space in Morges, Switzerland, which is leased to Accuray International until June 30, 2018. 56 In addition, our wholly-owned subsidiary, Accuray Accelerator Technology Company Limited, leases approximately 26,000 square feet of space in a manufacturing facility in Chengdu, China until July 2017. We, directly or through our subsidiaries, also maintain offices in: Pittsburgh, Pennsylvania; Durham, North Carolina; Switzerland; France; China; Hong Kong; Japan; Spain; India; Russia; Germany; Belgium; Brazil; and the United Arab Emirates. We believe our current facilities are adequate to meet our current needs, but additional space, including additional radiation shielded areas in which systems can be assembled and tested, may be required in the future to accommodate anticipated increases in manufacturing needs. Item 3. LEGAL PROCEEDINGS Refer to Note 8, Commitments and Contingencies, to the Consolidated Financial Statements for a description of certain legal proceedings currently pending against the Company. From time to time we are involved in legal proceedings arising in the ordinary course of our business. Item 4. MINE SAFETY DISCLOSURES Not applicable. 57 PART II Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Stock Information Our common stock is traded on the Nasdaq Global Select Market under the symbol ‘‘ARAY.’’ The high and low sale prices for each quarterly period during our fiscal years ended June 30, 2015 and 2014 are as follows: Year ended June 30, 2015 First Quarter . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Our Board of Directors intends to use any future earnings to support operations and reinvest in the growth and development of our business. There are no current plans to pay cash dividends to common stockholders in the foreseeable future. As of August 17, 2015, there were 190 registered stockholders of record of our common stock. Because many of our shares of common stock are held by brokers or other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial stockholders. During the year ended June 30, 2015, there were no sales of unregistered equity securities by the Company. In April 2014, the Company issued approximately $70.3 million aggregate principal amount of its 3.50% Series A Convertible Notes and paid approximately $0.4 million in cash to refinance approximately $70.3 million aggregate principal amount of its 3.50% Convertible Notes. None of the notes were registered. See the Company’s Current Report on Form 8- K filed on April 25, 2014 for a description of the new notes issued.

As a result, our results for the fiscal year ended June 30, 2011 include revenues, cost of revenues and operating expenses of TomoTherapy for the 20-day period from the acquisition date to the end of our fiscal year (June 30, 2011). Our results for the years ended June 30, 2015, 2014, 2013 and 2012 include revenues, cost of revenues and operating expenses of TomoTherapy for the full fiscal years. In addition, we made a number of purchase accounting adjustments to the recorded values of assets and liabilities acquired from TomoTherapy as of the acquisition date (June 10, 2011). (2) On December 21, 2012, we entered into a Purchase Agreement and Release with Compact Particle Acceleration Corporation, or CPAC, under which all the equity and debt investments held by us in CPAC were purchased by CPAC for a nominal consideration. As a result of the Purchase Agreement and Release, we concluded that we were no longer the primary beneficiary of CPAC, and therefore, deconsolidated CPAC as of December 21, 2012. The results of operations of CPAC, including the loss on deconsolidation of CPAC and the losses attributable to the non-controlling interest recorded for the years ended June 30, 2013, 2012 and 2011 have been reported as discontinued operations. Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS You should read the following discussion of our consolidated financial condition and results of operations in conjunction with the financial statements and the notes thereto included elsewhere in this report. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report on Form 10-K, particularly in ‘‘Risk Factors.’’ See ‘‘Special Note Regarding Forward-Looking Statements.’’ Overview Products and Markets Company We are a radiation oncology company that develops, manufactures, sells and supports precise, innovative treatment solutions which set the standard of care, with the aim of helping patients live longer, better lives. Our leading edge technologies, the CyberKnife(cid:4) and TomoTherapy Systems(cid:4), are designed to deliver advanced radiation therapy including radiosurgery, stereotactic body radiation therapy, intensity modulated radiation therapy, image guided radiation therapy and adaptive radiation therapy tailored to the specific needs of each patient. The CyberKnife and TomoTherapy Systems are complementary offerings serving separate patient populations treated by the same medical specialty, 61 radiation oncology, with advanced capabilities that offer increased treatment flexibility to meet the needs of an expanding patient population. The CyberKnife Systems are robotic systems designed to deliver radiosurgery treatments to cancer tumors anywhere in the body. The CyberKnife Systems are the only dedicated, full-body robotic radiosurgery systems on the market. Radiosurgery is an alternative to traditional surgery for tumors and is performed on an outpatient basis in one to five treatment sessions. It enables the treatment of patients who otherwise would not be treated with radiation, who may not be good candidates for surgery, or who desire non-surgical treatments. The use of radiosurgery with CyberKnife Systems to treat tumors throughout the body has grown significantly in recent years, but currently represents only a small portion of the patients who develop tumors treatable with CyberKnife Systems. A determination of when it may or may not be appropriate to use a CyberKnife System for treatment is at the discretion of the treating physician and depends on the specific patient. However, the CyberKnife Systems are generally not used to treat (1) very large tumors, which are considerably wider than the radiation beam that can be delivered by CyberKnife Systems, (2) diffuse wide-spread disease, as is often the case for late stage cancers, because they are not localized (though CyberKnife Systems might be used to treat a focal area of the disease) and (3) systemic diseases, like leukemia and lymphoma, which are not localized to an organ, but rather involve cells throughout the body. The addition of the multi-leaf collimator, or InCise MLC, now makes it faster and more efficient to treat a wider range of tumor types with the CyberKnife M6, including larger tumors and those with multiple sites of disease. Our CyberKnife M6 Series Systems have the option of: fixed collimator, iris collimator, and/or InCise MLC. The InCise MLC is designed specifically for the M6 Series. With the addition of the InCise MLC, clinicians can deliver the same precise radiosurgery treatments they have come to expect with the CyberKnife System, faster and for a wider range of tumor types. The InCise MLC was commercially launched in the third fiscal quarter of 2015. We believe the long term success of the CyberKnife Systems is dependent on a number of factors including the following: (cid:129) Continued adoption of our CyberKnife M6 Series Systems; (cid:129) Production and shipment of MLC that meets the standards that we, and our customers, expect in our products; (cid:129) Change in medical practice leading to utilization of stereotactic body radiosurgery more regularly as an alternative to surgery or other treatments; (cid:129) Greater awareness among doctors and patients of the benefits of radiosurgery with the CyberKnife Systems; (cid:129) Continued evolution in clinical studies demonstrating the safety, efficacy and other benefits of using the CyberKnife Systems to treat tumors in various parts of the body; (cid:129) Continued advances in technology that improve the quality of treatments and ease of use of the CyberKnife Systems; (cid:129) Improved access to radiosurgery with the CyberKnife Systems in various countries through regulatory approvals; (cid:129) Medical insurance reimbursement policies that cover CyberKnife System treatments; and (cid:129) Expansion of sales of CyberKnife Systems in countries throughout the world. The TomoTherapy Systems are advanced, fully integrated and versatile radiation therapy systems for the treatment of a wide range of cancer types. The TomoTherapy Systems are the only radiation 62 therapy systems designed for image-guided intensity-modulated radiation therapy (IG-IMRT). The TomoTherapy H Series Systems come in configurations of TomoHTM, TomoHDTM and TomoHDATM. Based on a CT scanner platform, the systems provide continuous delivery of radiation from 360 degrees around the patient, or delivery from clinician-specified beam angles. These unique features, combined with daily 3D image guidance, enable physicians to delivery highly accurate, individualized dose distributions which precisely conform to the shape of the patient’s tumor while minimizing dose to normal, healthy tissue, resulting in fewer side effects for patients. The TomoTherapy Systems are capable of treating all standard radiation therapy indications including breast, prostate, lung and head and neck cancers, in addition to complex treatments such as total marrow irradiation. Radiation therapy has been widely available and used in developed countries for decades, though many developing countries do not currently have a sufficient number of radiation therapy systems to adequately treat their domestic cancer patient populations. The number of radiation therapy systems in use and sold each year is currently many times larger than the number of radiosurgery systems. We believe the TomoTherapy Systems offer clinicians and patients significant benefits over other radiation therapy systems in the market. We believe our ability to capture more sales will be influenced by a number of factors including the following: (cid:129) Continued adoption of our TomoTherapy H Series Systems; (cid:129) Greater awareness among doctors and patients of the benefits of radiation therapy using TomoTherapy Systems; (cid:129) Advances in technology which improve the quality of treatments and ease of use of TomoTherapy Systems; (cid:129) Greater awareness among doctors of the now-established reliability of TomoTherapy Systems; and (cid:129) Expansion of TomoTherapy System sales in countries throughout the world. Sale of Our Products Generating revenue from the sale of our systems is a lengthy process. Selling our systems, from first contact with a potential customer to a signed sales contract that meets backlog criteria varies significantly and generally spans six months to two years. The time from receipt of a signed contract to revenue recognition is governed generally by the time required by the customer to build, renovate or prepare the treatment room for installation of the system. In the United States, we primarily market directly to customers, including hospitals and stand- alone treatment facilities, through our sales organization and we also market to customers through sales agents and group purchasing organizations. Outside the United States, we market to customers directly and through distributors and some sales agents. We have sales and service offices in many countries in Europe, Japan and other countries in Asia, South America, and throughout the world. Backlog For orders that cover both products and services, only the portion of the order that is recognizable as product revenue is reported as backlog. The portion of the order that is recognized as service revenue (for example, Post Contract Customer Support (PCS), installation, training and professional services) is not included in reported backlog. Product backlog totaled $375.0 million as of June 30, 2015. 63 In order for the product portion of a CyberKnife or TomoTherapy System sales agreement to be counted as backlog, it must meet the following criteria: (cid:129) The contract is signed and properly executed by both the customer and us. A customer purchase order that is signed and incorporates the terms of our contract quote will be considered equivalent to a signed and executed contract; (cid:129) The contract is non-contingent—it either has cleared all its contingencies or contains no contingencies when signed; (cid:129) We have received a minimum deposit or a letter of credit; the sale is a direct channel sale to a government entity, or the product has shipped to a customer with credit sufficient to cover the minimum deposit; (cid:129) The specific end customer site has been identified by the customer in the written contract or written amendment; (cid:129) For orders in our Latin America region, unless the system has already shipped and collection is reasonably assured, we request supporting evidence that the end customer has commenced construction to place our products if the site does not already exist; and (cid:129) Less than 2.5 years have passed since the contract met all the criteria above. Although our backlog includes only contractual agreements with our customers for the purchase of CyberKnife Systems, TomoTherapy Systems and related upgrades, we cannot provide assurance that we will convert backlog into recognized revenue due to factors outside our control. Our backlog is primarily impacted by three items: cancellations, age-outs and foreign currency fluctuations. Orders could be cancelled for reasons including, without limitation, changes in customers’ needs or financial condition, changes in government or health insurance reimbursement policies, changes to regulatory requirements, or other reasons. In addition to cancellations, after 2.5 years, if we have not been able to recognize revenue on a contract, we remove the revenue associated with the contract from backlog and the order is considered aged out. Contracts may age out for many reasons, including inability of the customer to pay, inability of the customer to adapt their facilities to accommodate our products in a timely manner, inability to timely obtain licenses necessary for customer facilities or operation of our equipment among other reasons for delays. Our backlog also includes amounts not denominated in U.S. Dollars and therefore fluctuations in the U.S. Dollar compared to other currencies will impact backlog. Generally, strengthening in the U.S. Dollar will negatively impact backlog. Gross orders are defined as the sum of new orders recorded during the period adjusted for any revisions to existing orders during the period. Net product orders are defined as gross product orders less cancellations, age-outs and foreign exchange adjustments.

Years ended June 30, 2015 2014 2013 $267,777 $188,997 $375,028 $263,352 $221,018 $364,742 $219,326 $171,659 $317,398 Gross orders increased by $4.4 million for the year ended June 30, 2015, as compared to the year ended June 30, 2014. Gross orders increased by $44.0 million for the year ended June 30, 2014, as compared to the year ended June 30, 2013. These increases were due to increased order volume year over year. In fiscal 2015, TomoTherapy System order volume increased 17% year over year and CyberKnife System order volume increased 12% year over year. In fiscal 2014, TomoTherapy System order volume increased 41% year over year and CyberKnife System order volume increased 10% year over year. 64 Net orders decreased by $32.0 million for the year ended June 30, 2015, as compared to the year ended June 30, 2014. Net orders increased by $49.4 million for the year ended June 30, 2014, as compared to the year ended June 30, 2013. Age-outs were $50.9 million, $38.3 million and $25.9 million in the years ended June 30, 2015, 2014 and 2013, respectively. Age-outs decreased significantly in the second half of fiscal 2015 from $36.0 million in the first half of fiscal 2015 as compared to $14.9 million in the second half of fiscal 2015. Currently, we expect to see year-over-year improvement in age-outs as a percentage of average backlog for fiscal 2016. Additionally, we expect age-outs in the first quarter of fiscal 2016 to be in a range of $20.0 million to $23.0 million as compared to the $17.8 million in age-outs recorded during the first quarter of fiscal 2015. Over the previous two fiscal years we have made changes to our order taking process, including increased oversight responsibility for and management of distributors and changes in timing as to when we enter some of our distributor orders into backlog. We believe these changes will improve the quality of backlog over time and reduce the level of age-outs when viewed as a percentage of backlog. Cancellations were $11.6 million, $4.1 million and $21.7 million in years ended June 30, 2015, 2014 and 2013, respectively. Cancellations are outside of our control and difficult to forecast; however, we continue to work closely with our customers to minimize this impact to our business. Additionally, both age-outs and cancellations exhibit significant variability on a quarter to quarter basis and we expect this will continue in fiscal 2016. In addition to age-outs and cancellations, order backlog was reduced due to foreign currency impacts of $16.3 million in the year ended June 30, 2015. This significant reduction due to foreign currency impacts is the result of having contracts based in several currencies such as Euro, Swiss Franc and Japanese Yen. When the U.S. Dollar strengthens, such as it did in fiscal year 2015, the result is a negative impact on the backlog. Conversely, order backlog was increased due to foreign currency impacts by $0.1 million and $0.7 million in the years ended June 30, 2014 and 2013, respectively due to a more stable U.S. Dollar.

Product net revenue increased primarily due to a higher number of units sold and product mix, partially offset by $7.5 million of foreign currency impacts due to the strengthening of the U.S Dollar. The number of units sold in fiscal 2015 increased by 4% as compared to fiscal 2014 driven by an increase in the number of CyberKnife Systems recognized into revenue, which was partially offset by a decrease in the number of TomoTherapy Systems recognized into revenue; however, as the CyberKnife Systems generally have a higher average selling price the overall net product revenue increased. In addition, product revenue upgrades increased by $3.0 million in fiscal 2015. Services net revenue increased by $5.3 million for the year ended June 30, 2015 as compared to the year ended June 30, 2014. The increase of $5.3 million was attributable to a net increase in our installed base and customer conversion to higher priced maintenance contracts (particularly the TomoTherapy Systems). This was partially offset by $6.7 million of foreign currency impacts due to the strengthening of the U.S. Dollar.

Product gross margin was 42% for the year ended June 30, 2015 as compared to 44% for the year ended June 30, 2014, representing a slight decrease of 2% also due to foreign currency impacts resulting from the strengthening of the U.S. Dollar. Services gross margin for the year ended June 30, 2015 was 35% as compared to 34% for the year ended June 30, 2014, representing a slight increase of 1% due mainly to continued revenue growth from the increase in installed base and contract mix accompanied by lower service part costs due to the continued increase in reliability of the TomoTherapy Systems all of which offset the foreign currency impacts resulting from the strengthening of the U.S. Dollar. Research and development expenses Research and development expenses were $55.8 million for the year ended June 30, 2015 as compared to $53.7 million for the year ended June 30, 2014, which represents an increase of $2.1 million, or 4%. The increase was primarily due to higher consulting fees associated with a development project that started in fiscal 2015 and resulted in an increase of $1.2 million compared to prior year. In addition, there was an increase of $1.2 million due to additional allocation and facilities expenses compared to prior year and an increase of $0.3 million in travel expenses as compared to prior year due to increased international travel. These increases were partially offset by decreased compensation expenses of $1.4 million driven by a $2.0 million reduction in incentive based compensation accrual expenses and a decrease of $0.7 million in contractor expenses; partially offset by 66 higher salaries of $0.8 million, an increase in recruiting and relocation fees of $0.1 million and increased stock-based compensation expenses of $0.5 million due to a higher number of grants. There were also increases due to $0.4 million in severance recorded in June 2015 related to terminations associated with departmental realignment. We anticipate that research and development expenses in fiscal 2016 will slightly increase compared with fiscal 2015 based on the current schedule of our development projects. Selling and marketing expenses Selling and marketing expenses for the year ended June 30, 2015 were $62.4 million as compared to $61.9 million for the year ended June 30, 2014, which represents an increase of $0.5 million, or 1%. The increase was partially attributable to a $2.8 million increase in compensation and compensation- related expenses, which consisted mainly of the increase in commission expense of $2.2 million due to higher sales, a $1.9 million increase in salaries and benefits expenses due to increases in personnel, and a $0.8 million increase in share-based compensation expense mainly due to an increase in grants of equity awards. These increases were partially offset by a decrease of $1.2 million in incentive based compensation accrual expenses and $0.9 million in decreased other compensation mainly related to decreased severance expenses in fiscal 2015 than those related to terminations in fiscal 2014. Consulting expenses also decreased $1.5 million due to significant marketing initiatives in fiscal 2014 with no similar projects in fiscal 2015. There were also decreases of $0.4 million in allocation expenses and $0.3 million in reduced sponsorships compared to prior year. We anticipate selling and marketing expenses in fiscal 2016 will be slightly down compared with fiscal 2015 due to increased expense control offset by increases in headcount. General and administrative expenses General and administrative expenses for the year ended June 30, 2015 were $46.4 million as compared to $45.3 million for the year ended June 30, 2014, which represents an increase of $1.1 million, or 2%. This increase was primarily related to higher legal expenses of $3.5 million due to ongoing defense and response to legal matters, primarily related to the Cowealth Medical matter described in Note 8 to the financial statements. In addition, there was increased stock-based compensation of $1.3 million due to increased grants. These increases were partially offset by reductions in incentive based compensation accrual expenses of $2.0 million as compared to prior year and a $1.0 million decrease in restructuring costs as compared to prior year. Additionally, consulting fees decreased $0.7 million due to fewer projects in fiscal 2015 as compared to fiscal 2014. We anticipate general and administrative expenses in fiscal 2016 will be slightly down compared with fiscal 2015 due to decreased legal fees and consulting expenses. Other expense, net Net other expense for the year ended June 30, 2015 was $18.6 million as compared to $14.2 million for the year ended June 30, 2014, which represents an increase of $4.4 million. This increase was primarily due to increased foreign currency losses of $2.5 million primarily due to a stronger U.S. Dollar in comparison to the Euro, Japanese Yen and the Swiss Franc. Additionally, non cash interest expense increased by $2.2 million due to the refinancing of our 3.50% Convertible Notes into 3.50% Series A Convertible Notes in the fourth quarter of fiscal 2014. 67 Provision for income taxes The provision for income taxes was lower in fiscal 2015 compared to fiscal 2014 mainly due to the activities in international locations—reduction of benefits related to uncertain tax positions and decreased foreign earnings. At June 30, 2015, we had federal and state net operating loss carryforwards of $329.6 million and $157.5 million, respectively. These federal and state net operating loss carryforwards are available to offset future taxable income, if any, in varying amounts and will begin to expire in 2019 for federal and 2016 for state purposes, respectively. Such net operating loss carryforwards include tax benefits from employee stock option exercises in excess of the share-based compensation expense that has been recognized for these awards. We will record approximately $3.9 million as a credit to additional paid-in capital if and when such excess benefits are ultimately realized. We also had federal and state research and development tax credit carryforwards of approximately $16.3 million and $16.5 million, respectively. If not utilized, the federal research credits will begin to expire in 2019, the California research credits have no expiration date and the other state research credits begin to expire in 2016. Realization of the deferred tax assets, among other factors, is dependent on our ability to generate sufficient taxable income prior to the expiration of the carryforwards. Due to the inconsistent history of net operating income as adjusted for permanent differences, we cannot conclude that the net domestic deferred tax assets will more likely than not be realized. Accordingly, we have recorded a full valuation allowance against our domestic net deferred tax assets. At June 30, 2015, there was no provision for U.S. income tax for undistributed earnings of our foreign subsidiaries as it is currently our intention to reinvest these earnings indefinitely in operations outside the U.S. The cumulative amount of such undistributed earnings upon which no U.S. income tax have been provided as of June 30, 2015 was $20.3 million. If repatriated, these earnings could result in a tax expense at the current U.S. Federal statutory tax rate of 35%, subject to available net operating losses and other factors. Subject to limitation, tax on undistributed earnings may also be reduced by foreign tax credits that may be generated in connection with the repatriation of earnings.

As a result of the Purchase Agreement and Release, we concluded that we were no longer the primary beneficiary of CPAC, and therefore, deconsolidated CPAC as of December 21, 2012. The results of operations of CPAC, including the loss on deconsolidation of CPAC and the losses attributable to the non-controlling interest recorded for the year ended June 30, 2013, has been reported as discontinued operations. Refer to Note 7, ‘‘Investment in CPAC’’ for further details. Net revenue Product net revenue increased by $36.2 million for the year ended June 30, 2014 as compared to the year ended June 30, 2013. Product net revenue increased primarily due to a higher number of units sold offset by product mix. The number of units sold in fiscal 2014 increased by 40% as compared to fiscal 2013. In addition, product revenue upgrades increased by $3.0 million in fiscal 2014. Services net revenue increased by $17.2 million for the year ended June 30, 2014 as compared to the year ended June 30, 2013. The increase of $13.2 million was attributable to a net increase in our installed base and customer conversion to higher priced maintenance contracts (particularly the TomoTherapy Systems). The remaining increase of $4.0 million was primarily due to an increase in installation, training and spare parts revenue due to the increased number of units installed.

Product gross margin for fiscal 2014 increased by 6 margin points as compared to fiscal 2013 mostly due to increased revenues reducing fixed costs per unit, reduction in charges for obsolete or excess inventory, and due to the favorable impact of a net reduction in backlog intangible asset amortization expense of $1.6 million resulting from the acquisition of TomoTherapy on June 10, 2011. Services gross margin for the year ended June 30, 2014 increased by 8 margin points primarily due to cost reductions associated with the increased reliability of the TomoTherapy Systems and continued revenue growth due to the increase in installed base and contract mix, partially offset by the increase in bonus expense. Research and development expenses Research and development expenses were $53.7 million for the year ended June 30, 2014 as compared to $66.2 million for the year ended June 30, 2013, which represents a decrease of $12.5 million, or 19%. The decrease was primarily due to lower compensation expense of $12.0 million resulting from the re-organization of the research and development function during the third quarter of fiscal 2013. Additionally, project related consulting costs decreased by $4.3 million due to the completion of various research and development projects. The decrease was offset by the higher bonus expense of $3.2 million and higher share-based compensation expense of $0.6 million. 69 Selling and marketing expenses Selling and marketing expenses for the year ended June 30, 2014 were $61.9 million as compared to $54.4 million for the year ended June 30, 2013, which represents an increase of $7.5 million, or 14%. The increase was partially attributable to a $8.0 million increase in compensation and compensation related expenses, which consisted mainly of the increase in commission expense of $2.9 million due to higher sales, a $2.0 million increase in bonus expense, a $2.1 million increase in payroll expense due to increases in personnel and a $0.9 million increase in share-based compensation expense mainly due to the increase in grants of equity awards and higher values per grant. Consulting expense increased by $0.5 million due to sales optimization initiatives. The increase was offset by lower trade show expense of $1.5 million, which was higher for the year ended June 30, 2013 due to the introduction of two new products at an industry trade show during fiscal 2013. General and administrative expenses General and administrative expenses for the year ended June 30, 2014 were $45.3 million as compared to $57.7 million for the year ended June 30, 2013, which represents a decrease of $12.4 million, or 21%. This decrease was partially attributable to $7.4 million of severance charges incurred in fiscal 2013 for the departure of our former Chief Executive Office, Chief Operating Officer and other employees, and $1.7 million related to lease acceleration and fixed asset disposal charges from vacating an office facility in fiscal 2013. The allowance for doubtful accounts expense decreased by $1.5 million in fiscal 2013 due to improved cash collections. In addition, payroll and contractual labor expenses decreased by $2.2 million and consulting, legal and accounting related expenses decreased by $2.5 million due to cost control initiatives. The decrease was offset by higher bonus expense of $2.4 million and higher share-based compensation expense of $1.1 million during the year ended June 30, 2014 as compared to the year ended June 30, 2013. Other income (expense), net Net other expense for the year ended June 30, 2014 was $14.2 million as compared to $13.1 million for the year ended June 30, 2013, which represents an increase of $1.1 million. In fiscal 2014, we recognized $14.3 million of interest expense related to our Convertible Notes, partially offset by interest income of $0.6 million from our available-for-sale investments and a $0.1 million gain from foreign currency exchange. We also incurred $0.6 million other expense in fiscal 2014 primarily related to the exchange of our 3.50% Convertible Notes to the 3.50% Series A Convertible Notes in April 2014. In fiscal 2013, we recognized net other expense of $13.1 million primarily due to $10.4 million of interest expense related to our Convertible Notes and $2.7 million of foreign currency losses primarily resulting from the depreciation of the Japanese Yen against the U.S. Dollar and the appreciation of the Euro against the U.S. Dollar. Provision for income taxes The provision for income taxes was lower in fiscal 2014 compared to fiscal 2013 mainly due to the activities in international locations—reduction of benefits related to uncertain tax positions offset by the increased foreign earnings. At June 30, 2014, we had federal and state net operating loss carryforwards of $320.5 million and $166.8 million, respectively. These federal and state net operating loss carryforwards are available to offset future taxable income, if any, in varying amounts and will begin to expire in 2019 for federal and 2015 for state purposes, respectively. Such net operating loss carryforwards include tax benefits from employee stock option exercises in excess of the share-based compensation expense that has been recognized for these awards. We will record approximately $3.9 million as a credit to additional paid-in capital if and when such excess benefits are ultimately realized. We also had federal and state research 70 and development tax credit carryforwards of approximately $16.1 million and $15.7 million, respectively. If not utilized, the federal research credits will begin to expire in 2019, the California research credits have no expiration date and the other state research credits begin to expire in 2015. Realization of the deferred tax assets, among other factors, is dependent on our ability to generate sufficient taxable income prior to the expiration of the carryforwards. Due to the inconsistent history of net operating income as adjusted for permanent differences, we cannot conclude that the net domestic deferred tax assets will more likely than not be realized. Accordingly, we have recorded a full valuation allowance against our domestic net deferred tax assets. At June 30, 2014, there was no provision for U.S. income tax for undistributed earnings of our foreign subsidiaries as it is currently our intention to reinvest these earnings indefinitely in operations outside the U.S. The cumulative amount of such undistributed earnings upon which no U.S. income tax have been provided as of June 30, 2014 was $14.7 million. If repatriated, these earnings could result in a tax expense at the current U.S. Federal statutory tax rate of 35%, subject to available net operating losses and other factors. Subject to limitation, tax on undistributed earnings may also be reduced by foreign tax credits that may be generated in connection with the repatriation of earnings. Loss from Discontinued Operations The results of operations of CPAC, including the loss on deconsolidation of CPAC and the losses attributable to the non-controlling interest recorded for the years ended June 30, 2013 and 2012 were disclosed as discontinued operations. Impairment of Indefinite Lived Intangible Assets In fiscal 2013, we incurred impairment charges of $12.2 million related to the write-down of our in-process research and development, or IPR&D, asset based on results of research and development work carried out by CPAC, then a variable interest entity consolidated by us. See Note 6, ‘‘Goodwill and Purchased Intangible Assets’’, to the consolidated financial statements for details. Loss from Deconsolidation of CPAC On December 21, 2012, we entered into a Purchase Agreement and Release with CPAC, under which all the equity and debt investments held by us in CPAC were purchased by CPAC for a nominal consideration. As a result of the Purchase Agreement, we concluded that we were no longer the primary beneficiary of CPAC, and therefore, deconsolidated CPAC as of that date. We recorded a loss of $3.4 million in the second quarter of fiscal 2013 due to the write-down of the carrying value of CPAC’s net liabilities, the write-off of the receivables from CPAC and the non-controlling interest in CPAC, net of cash consideration received. Share-based Compensation Expense In fiscal 2015, 2014 and 2013, we recorded share-based compensation expense of $13.9 million, $11.3 million and $8.2 million, respectively, related to awards under our incentive stock plans and restricted stock awards, or RSAs, assumed in connection with the acquisition of TomoTherapy. Share- based compensation expense was recorded net of estimated forfeitures (excludes share-based awards not expected to vest). As of June 30, 2015, we had approximately $19.4 million of unrecognized compensation expense, net of estimated forfeitures, related to unvested stock options, Employee Stock Purchase Plan, or ESPP shares, restricted stock units, or RSUs, market stock units, or MSUs, which we expect to recognize over a weighted average period from 0.6 to 2.2 years. 71 Liquidity and Capital Resources At June 30, 2015, we had $79.6 million in cash and cash equivalents and $64.3 million in investments. Cash from operations could be affected by various risks and uncertainties, including, but not limited to the risks included in Part I, Item 1A titled ‘‘Risk Factors.’’ Also refer to Note 13, ‘‘Debt’’ to the consolidated financial statements for discussion of the Convertible Notes. Based on our current business plan and revenue prospects, we believe that we will have sufficient cash resources and anticipated cash flows to fund our operations for at least the next 12 months. In addition, the undistributed earnings of our foreign subsidiaries at June 30, 2015 are considered to be indefinitely reinvested and unavailable for distribution in the form of dividends or otherwise. Accordingly, no provisions for U.S. income taxes have been provided thereon. We anticipate that we have adequate liquidity and capital resources and would not need to repatriate earnings. As of June 30, 2015, we had approximately $51.2 million of cash and cash equivalents at our foreign subsidiaries.

Net cash used in operating activities in fiscal 2015 was primarily related to: (cid:129) Net loss of $40.2 million; (cid:129) Net loss offset by non-cash items of $45.4 million related to depreciation of fixed assets, amortization of intangible assets, share-based compensation, amortization and accretion of discount and premium on investments, amortization of debt issuance costs, accretion of interest on long-term debt, loss on disposal of property and equipment, and provision for excess and obsolete inventory; (cid:129) Increase in restricted cash of $2.4 million due to a contractual guarantee requirement; (cid:129) Increase in accounts receivable of $8.3 million as a result of increased sales of $10.4 million offset by cash collections from customers in fiscal 2015; (cid:129) Increase in inventories of $21.1 million due to increase in purchases to support future sales and service needs; (cid:129) Decrease in prepaid expenses and other assets of $2.3 million primarily due to the reduction of prepaid taxes of $1.7 million primarily in foreign locations due to settlements, a reduction in debt related costs of $1.5 million due to continued amortization, and a decrease in prepaid commissions of $1.0 million due to the conversion of deferred revenue into revenue in fiscal 2015. These decreases were partially offset by increases in the prepaid benefits balance of $0.5 million due to the timing of payments, higher other prepaids due to additional vendor 72 advances of $0.8 million, and an increase in prepaid maintenance of $0.4 million due to several new software agreements; (cid:129) Decrease in accounts payable of $1.8 million due to lower billings as a result of timing; (cid:129) Decrease in accrued liabilities of $8.6 million primarily related to the bonus accrual reduction of $8.4 million due to bonus payments relating to fiscal 2014 made in the first fiscal quarter of 2015 offset by additional accrual for bonuses for the current fiscal year. Accrued payroll decreased $2.1 million due to the timing of the year-end payroll cut-off and sales tax payable decreased in the U.S. by $0.5 million due to process improvements in timely payments. Income tax payable also decreased by $1.5 due to the timing of filing and payments for fiscal 2014. These decreases were partially offset by an increase of $3.5 million in deferred rent due to a renegotiated lease agreement; (cid:129) Increase in customer advances of $0.6 million due to the payments received for the future revenue deliverables; and (cid:129) Increase in deferred revenue of $9.7 million due to the timing of customer billing and revenue recognition, and decrease in deferred cost of $7.8 million due to the timing of inventory transfer. Net cash provided by operating activities was $0.3 million in fiscal 2014 as compared to $66.2 million used in 2013. Net cash provided by operating activities in 2014 was primarily related to: (cid:129) Net loss of $35.4 million; (cid:129) Net loss offset by non-cash items of $42.9 million related to depreciation of fixed assets, amortization of intangible assets, share-based compensation, amortization and accretion of discount and premium on investments, amortization of debt issuance costs, accretion of interest on long-term debt, recovery of doubtful accounts receivable, loss on disposal of property and equipment, and provision for excess and obsolete inventory; (cid:129) Increase in accounts receivable of $14.8 million as a result of increased sales of $53.4 million offset by cash collections from customers in fiscal 2014; (cid:129) Increase in inventories of $8.3 million due to increase in purchases to support sales; (cid:129) Increase in prepaid expenses and other assets of $5.2 million primarily due to the increase in prepaid commissions balance of $2.8 million as a result of the increase in orders and prepaid taxes of $2.9 million mostly in foreign locations; (cid:129) Decrease in accounts payable of $1.1 million due to the timing of payments; (cid:129) Increase in accrued liabilities of $21.7 million primarily due to the increase in accrued bonus expense of $14.2 million, increase in other accrued compensation related expense of $6.0 million; (cid:129) Increase in customer advances of $1.7 million due to the payments received for the future revenue deliverables; and (cid:129) Increase in deferred revenue of $4.0 million due to the timing of customer billing and revenue recognition, and increase deferred cost of $4.9 million due to the timing of inventory transfer. Cash Flows From Investing Activities Net cash provided by investing activities was $3.7 million in fiscal 2015, which primarily consisted of sales and maturities of short-term investments of $121.3 million, offset by purchases of property and equipment of $10.4 million and purchases of investments of $107.2 million. 73 Net cash provided by investing activities was $8.5 million in fiscal 2014, which primarily consisted of sales and maturities of short-term investments of $64.6 million, offset by purchases of property and equipment of $11.9 million and purchases of investments of $44.2 million. Cash Flows From Financing Activities Net cash provided by financing activities during fiscal 2015 was $5.9 million, attributable to $6.6 million from proceeds from employee stock plans, partially offset by $0.7 million of taxes paid related to net share settlement of equity awards. Net cash provided by financing activities during fiscal 2014 was $8.4 million, attributable to $9.1 million from proceeds from employee stock plans, partially offset by $0.3 million of taxes paid related to net share settlement of equity awards and $0.4 million in payments to convertible note holders to refinance approximately $70.3 million aggregate principal amount of our 3.50% Convertible Notes. Operating Capital and Capital Expenditure Requirements Our future capital requirements depend on numerous factors. These factors include but are not limited to the following: (cid:129) Revenue generated by sales of our products and service plans; (cid:129) Costs associated with our sales and marketing initiatives and manufacturing activities; (cid:129) Facilities, equipment and IT systems required to support current and future operations; (cid:129) Rate of progress and cost of our research and development activities; (cid:129) Costs of obtaining and maintaining FDA and other regulatory clearances of our products; (cid:129) Effects of competing technological and market developments; (cid:129) Number and timing of acquisitions and other strategic transactions. We believe that our current cash, cash equivalents and investments will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least 12 months. If these sources of cash, cash equivalents and investments are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities or obtain additional credit facilities. The sale of additional equity or convertible debt securities could result in dilution to our stockholders. If additional funds are raised through the issuance of debt securities, these securities could have rights senior to those associated with our common stock and could contain covenants that would restrict our operations. Additional financing may not be available at all, or in amounts or on terms acceptable to us. If we are unable to obtain this additional financing, we may be required to reduce the scope of our planned product development and marketing efforts. 74 Contractual Obligations and Commitments The following is a schedule summarizing our obligations to make future payments under contractual obligations as of June 30, 2015: Payments due by period (in thousands) Total Less than 1 year 1 - 3 years 3 - 5 years More than 5 years Convertible Notes(1) . . . . . . . . . . . . . . . . . . . .

Our purchase commitments and obligations include all open purchase orders and contractual obligations in the ordinary course of business, including commitments with contract manufacturers and suppliers, for which we have not received the goods or services and acquisition and licensing of intellectual property. A majority of these purchase obligations are due within a year. Although open purchase orders are considered enforceable and legally binding, the terms generally allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to the delivery of goods or performance of services, and hence, have not been included in the table above. Off Balance Sheet Arrangements We do not have any off balance sheet arrangements. Critical Accounting Policies and Estimates The discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as revenue and expenses during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Actual results could therefore differ materially from those estimates if actual conditions differ from our assumptions. All of our significant accounting policies and methods used in the preparation of our consolidated financial statements are described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements. The methods, estimates and judgments that we use in applying our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain. Management believes the critical accounting policies and estimates are those related to revenue recognition, business combinations and assessment of recoverability of goodwill and intangible assets, valuation of inventories, share-based compensation expense, convertible notes, income taxes, allowance for doubtful accounts and loss contingencies. 75 Revenue Recognition We frequently enter into sales arrangements with customers that contain multiple elements or deliverables and we have to make a number of reasoned judgments with respect to elements of these sales arrangements, including how to allocate the proceeds received from an arrangement, whether there are multiple elements in the arrangement, whether any undelivered elements are essential to the functionality of the delivered elements and the appropriate timing of revenue recognition with respect to these arrangements. For sale arrangements that contain multiple elements, we allocate the arrangement consideration to each element based on the relative selling price method, whereby the relative selling price of each deliverable is determined using vendor specific objective evidence, or VSOE, of fair value, if it exists. VSOE of fair value for each element is based on our standard rates charged for the product or service when such product or service is sold separately or based upon the price established by the Company’s pricing committee when that product or service is not yet being sold separately. When we are not able to establish VSOE for all deliverables in an arrangement with multiple elements, which may be due to us infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history, we attempt to determine the selling price of each element based on third-party evidence of selling price, or TPE, as determined based on competitors’ prices for similar deliverables when sold separately. TPE typically is difficult to establish due to the proprietary differences of competitive products and difficulty in obtaining reliable competitive standalone pricing information. When we are not able to establish selling price using VSOE or TPE, we use our best estimate of selling price, or BESP, in the allocation of arrangement consideration. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. We determine BESP for a product or service by considering multiple factors including, but not limited to, pricing practices, internal costs, geographies and gross margin. The determination of BESP is made through annual analysis of our pricing practices and adjusted if necessary. Revenue recognition also depends on all or a combination of the following: timing of shipment, completion of installation, customer acceptance and the readiness of customers’ facilities. If shipments are not made on scheduled timelines, installation schedules are delayed or if the products are not accepted by the customer in a timely manner, our reported revenues may differ materially from expectations. Business Combinations and Assessment of Recoverability of Goodwill and Intangible Assets Our methodology for allocating the purchase price relating to business combinations is determined through established valuation techniques. The allocation of the purchase price to intangible assets requires us to make significant estimates and assumptions, including estimates of future cash flows expected to be generated by the acquired assets and appropriate discount rate for those cash flows. Goodwill represents the excess of the purchase price over the fair value of tangible and identified intangible net assets of businesses acquired. Goodwill is not amortized, but is evaluated for impairment on an annual basis and when impairment indicators are present. We have one operating segment and one reporting unit. Therefore, our consolidated net assets, including existing goodwill and other intangible assets, are considered to be the carrying value of the reporting unit. We estimate the fair value of the reporting unit based on the closing price of our common stock on the trading day closest to the annual review date multiplied by the outstanding shares on that date. If the carrying value of the reporting unit is in excess of its fair value, an impairment may exist, and we must perform the second step of the analysis, in which the implied fair value of the goodwill is compared to its carrying value to determine the impairment charge, if any. If the estimated fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and no further analysis is required. We make judgments about the recoverability of purchased intangible assets with finite lives whenever events or changes in circumstances indicate that impairment may exist. Recoverability of 76 purchased intangible assets with finite lives is measured by comparing the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. Impairment, if any, is measured as the amount by which the carrying value exceeds the fair value of the impaired asset. We review indefinite-lived intangible assets for impairment annually or whenever events or changes in circumstances indicate the carrying value may not be recoverable. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. Assumptions and estimates about future values and remaining useful lives of our purchased intangible assets are complex and subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends and internal factors such as changes in our business strategy and our internal forecasts. Valuation of Inventories The valuation of inventory requires us to estimate obsolete or excess inventory as well as damaged inventory. The determination of obsolete or excess inventory requires us to estimate the future demand for our products. We regularly review inventory quantities on hand and adjust for excess and obsolete inventory based primarily on historical usage rates and our estimates of product demand to support future sales and service. If our demand forecast for specific products is greater than actual demand and we fail to reduce purchasing and manufacturing output accordingly, we could be required to write off inventory beyond the current reserve, which would negatively impact our gross margin. Share-Based Compensation Expense We use the Black-Scholes option valuation model to estimate the fair value of stock options and ESPP shares. These valuation models require the input of highly subjective assumptions, the most significant of which is our estimates of expected volatility and the expected term of the award. Our expected volatility is derived from the historical volatilities of our common stock. Prior to the second quarter of fiscal 2013, our expected volatility was based on the historical volatilities of several unrelated public companies within industries related to our business. We estimate the expected term of stock option by taking the average of the vesting term and the contractual term of the option, as illustrated by the simplified method. We use the Monte-Carlo simulation model to estimate the fair value of Market Stock Units, or MSUs. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our share-based compensation expense could be materially different in the future. We recognize compensation cost for only those shares expected to vest over the requisite service period of the award. We estimate our forfeiture rate based on an analysis of our actual forfeitures and will continue to evaluate the appropriateness of the forfeiture rate based on recent forfeiture activity and expected future employee turnover. Changes in the estimated forfeiture rate can have a significant effect on reported share-based compensation expense, as the cumulative effect of adjusting the rate for all expense amortization is recognized in the period the forfeiture estimate is changed. Convertible Notes We account for convertible notes in accordance with ASC 470-20 Debt with Conversion and Other Options. ASC 470-20 clarifies the accounting for convertible debt instruments that may be settled in cash upon conversion, including partial cash settlement at our election. ASC 470-20 specifies that an issuer of such instruments should separately account for the liability and equity component of the conversion option. The amount recorded as debt is based on the fair value of the debt component as a 77 standalone instrument, determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to ours at the time of issuance. The difference between the debt recorded at inception and its principal amount is accreted to principal during the estimated life of the note. Income Taxes We determine our current and deferred tax provisions based on estimates and assumptions that could differ from the actual results reflected in our income tax returns filed during the subsequent year. We record adjustments based on filed returns when we have identified and finalized them, which is generally in the fourth quarter of the subsequent year for U.S. federal and state provisions. We have placed a full valuation allowance on all net U.S. deferred tax assets because realization of these tax benefits through future taxable income cannot be reasonably assured. We intend to maintain the valuation allowance until sufficient positive evidence exists to support the reversal of the valuation allowance. Any decision to reverse part or all of the valuation allowance would be based on our estimate of future profitability. If our estimate were to be wrong, we could be required to charge potentially significant amounts to income tax expense to establish a new valuation allowance. Our effective tax rate includes the impact of certain undistributed foreign earnings for which we have not provided U.S. taxes because we plan to reinvest such earnings indefinitely outside the United States. We plan foreign earnings remittance amounts based on projected cash flow needs as well as the working capital and long-term investment requirements of our foreign subsidiaries and our domestic operations. Material changes in our estimates of cash, working capital and long-term investment requirements in the various jurisdictions in which we do business could impact our effective tax rate. We are subject to income taxes in the United States and certain foreign countries, and we are subject to corporate income tax audits in some of these jurisdictions. We believe that our tax return positions are fully supported, but tax authorities are likely to challenge certain positions, which may not be fully sustained. However, our income tax expense includes amounts intended to satisfy income tax assessments that result from these challenges. Determining the income tax expense for these potential assessments and recording the related assets and liabilities requires management judgments and estimates. We evaluate our uncertain tax positions in accordance with the guidance for accounting for uncertainty in income taxes. We believe that our reserve for uncertain tax positions is adequate. We review our reserves quarterly, and we may adjust such reserves because of proposed assessments by tax authorities, changes in facts and circumstances, issuance of new regulations or new case law, previously unavailable information obtained during the course of an examination, negotiations between tax authorities of different countries concerning our transfer prices, or the expiration of statutes of limitations. Allowance for Doubtful Accounts We evaluate the creditworthiness of our customers prior to authorizing shipment for all major sale transactions. On a quarterly basis, we evaluate aged items in the accounts receivable aging report and provide an allowance in an amount we deem adequate for doubtful accounts. If our evaluation of our customers’ financial conditions does not reflect our future ability to collect outstanding receivables, additional provisions may be needed and our operating results could be negatively affected. Loss Contingencies As discussed in Note 8, Commitments and Contingencies, to the consolidated financial statements, we are involved in various lawsuits, claims and proceedings that arise in the ordinary course of business. We record a provision for a liability when we believe that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. We review these provisions at least quarterly and 78 adjust these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Litigation is inherently unpredictable and is subject to significant uncertainties, some of which are beyond our control. Should any of these estimates and assumptions change or prove to have been incorrect, we could incur significant charges related to legal matters which could have a material impact on our results of operations, financial position and cash flows. Item 7A. QUANTITATIVE & QUALITATIVE DISCLOSURES ABOUT MARKET RISK We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions. Foreign Currency Exchange Rate Risk A portion of our net sales are denominated in foreign currencies, most notably the Euro and the Japanese Yen. Future fluctuations in the value of the U.S. Dollar may affect the price competitiveness of our products outside the United States. For direct sales outside the United States, we sell in both U.S. Dollars and local currencies, which could expose us to additional foreign currency risks, including changes in currency exchange rates. Our operating expenses in countries outside the United States, are payable in foreign currencies and therefore expose us to currency risk. To the extent that management can predict the timing of payments under sales contracts or for operating expenses that are denominated in foreign currencies, we may engage in hedging transactions to mitigate such risks in the future. We expect the changes in the fair value of the intercompany receivables arising from fluctuations in foreign currency exchange rates to be materially offset by the changes in the fair value of the forward contracts. As of June 30, 2015, we had no open forward contracts and all open positions had been settled. The purpose of these forward contracts is to minimize the risk associated with foreign exchange rate fluctuations. We have developed a foreign exchange policy to govern our forward contracts. These foreign currency forward contracts do not qualify as cash flow hedges and all changes in fair value are reported in earnings as part of other income and expenses. We have not entered into any other types of derivative financial instruments for trading or speculative purpose. Our foreign currency forward contract valuation inputs are based on quoted prices and quoted pricing intervals from public data and do not involve management judgment. Interest Rate Risk We maintain an investment portfolio of various holdings, types, and maturities. These securities are generally classified as available for sale and consequently, are recorded on the balance sheet at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income. At any time, a sharp rise or decline in interest rates could have a material adverse impact on the fair value of our investment portfolio. Likewise, increases and decreases in interest rates could have a material impact on interest earnings for our portfolio. The following table presents the hypothetical change in fair values in the financial instruments we held at June 30, 2015 that are sensitive to changes in interest rates. The modeling technique used measures the change in fair values arising from selected potential changes in interest rates on our investment portfolio, which had a fair value of $64.3 million at June 30, 2015. Market changes reflect immediate hypothetical parallel shifts in the yield curve of plus or minus 100, 75, 50 and 25 basis points (in thousands). Change in interest rate Decrease in interest rates (cid:6)100 BPS (cid:6)75 BPS (cid:6)50 BPS (cid:6)25 BPS Increase in interest rates 25 BPS 50 BPS 75 BPS 100 BPS Unrealized gain (loss) . . . . $337 $297 $224 $120 $(121) $(242) $(364) $(486) 79 Equity Price Risk On August 1, 2011, we issued $100 million aggregate principal amount of 3.75% Convertible Notes. Upon conversion, we can settle the obligation by issuing our common stock, cash or a combination thereof at an initial conversion rate equal to 105.5548 shares of common stock per $1,000 principal amount of the 3.75% Convertible Notes, which is equivalent to a conversion price of approximately $9.47 per share of common stock, subject to adjustment. There is no equity price risk if the share price of our common stock is below $9.47 upon conversion of the 3.75% Convertible Notes. For every $1 that the share price of our common stock exceeds $9.47, we expect to issue an additional $10.6 million in cash or shares of our common stock, or a combination thereof, if all of the 3.75% Convertible Notes are converted. On April 24, 2014, we issued approximately $70.3 million aggregate principal amount of 3.50% Series A Convertible Notes. Upon conversion, we can settle the obligation by issuing our common stock, cash or a combination thereof at an initial conversion rate equal to 187.6877 shares of common stock per $1,000 principal amount of the 3.50% Series A Convertible Notes, which is equivalent to a conversion price of approximately $5.33 per share of common stock, subject to adjustment. There is no equity price risk if the share price of our common stock is below $5.33 upon conversion of the 3.50% Series A Convertible Notes. For every $1 that the share price of our common stock exceeds $5.33, we expect to issue an additional $13.2 million in cash or shares of our common stock, or a combination thereof, if all of the 3.50% Series A Convertible Notes are converted. 80 Item 8.

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Accuray Incorporated and subsidiaries as of June 30, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 2015 in conformity with accounting principles generally accepted in the United States of America. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of June 30, 2015, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated August 28, 2015 expressed an unqualified opinion. /s/ GRANT THORNTON LLP San Francisco, California August 28, 2015 82 Accuray Incorporated Consolidated Balance Sheets (in thousands, except share and per share amounts) June 30, 2015 June 30, 2014 Assets Current assets: Cash and cash equivalents . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Description of Business Organization Accuray Incorporated (together with its subsidiaries, the ‘‘Company’’ or ‘‘Accuray’’) is incorporated in Delaware. The Company designs, develops and sells advanced radiosurgery and radiation therapy systems for the treatment of tumors throughout the body. The Company conducts its business worldwide. The Company has its headquarters in Sunnyvale, California, with additional locations worldwide. 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with GAAP, pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and a variable interest entity, Compact Particle Acceleration Corporation, or CPAC until the deconsolidation of CPAC on December 21, 2012 (for further information, see Note 7, Investment in CPAC). All significant inter-company transactions and balances have been eliminated in consolidation. Discontinued Operations As a result of the deconsolidation of CPAC, the results of operations of CPAC, including the loss on deconsolidation of CPAC and the loss attributable to the non-controlling interest recorded for the year ended June 30, 2013 has been presented as discontinued operations. 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, liabilities, revenues, expenses, and related disclosures at the date of the financial statements. Key estimates and assumptions made by the Company relate to revenue recognition, business combinations and assessment of recoverability of goodwill and intangible assets, valuation of inventories, share-based compensation expense, convertible notes, income taxes, allowance for doubtful accounts and loss contingencies. Actual results could differ materially from those estimates. Foreign Currency The Company’s international subsidiaries use their local currencies as their functional currencies. For those subsidiaries, assets and liabilities are translated at exchange rates in effect at the balance sheet date and income and expense accounts at the average exchange rate. Resulting translation adjustments are excluded from the determination of net loss and are recorded in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Net foreign currency exchange transaction gains or losses are included as a component of other income (expense), net, in the Company’s consolidated statements of operations and comprehensive loss. Fair Value Measurements The carrying values of the Company’s financial instruments including cash equivalents, restricted cash, accounts receivable and accounts payable are approximately equal to their respective fair values 87 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) due to the relatively short-term nature of these instruments. Also refer to Note 4, Financial Instruments, for further details. Cash and Cash Equivalents The Company considers currency on hand, demand deposits, time deposits, and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash equivalents are held in various financial institutions in the United States and internationally. Investments The Company classifies all its investments as available-for-sale at the time of purchase since it is management’s intent that these investments be available for current operations, and as such, includes these investments as short-term investments on its balance sheets. These investments primarily consist of commercial paper and investment-grade agency and corporate debt securities with original maturities longer than three months. Short-term investments classified as available-for-sale are recorded at fair market value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are recorded in the consolidated statements of operations and comprehensive loss based on specific identification. Concentration of Credit Risk and Other Risks and Uncertainties The Company’s cash and cash equivalents are mainly deposited with several major financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. The Company has not experienced any losses in such accounts and believes that it is not exposed to any significant risk on these balances. The Company has placed its investments with high-credit quality issuers. The Company does not invest an amount exceeding 5% of its combined cash, cash equivalents and investments in the securities of any one obligor or maker, except for obligations of the United States government, obligations of United States government agencies and money market accounts. There were no customers that represented 10% or more of total net revenue for the years ended June 30, 2015, 2014 and 2013. At June 30, 2015, one customer accounted for 18% of accounts receivable. At June 30, 2014, one customer accounted for 13% of accounts receivable. Accounts receivable are typically not collateralized. The Company performs ongoing credit evaluations of its customers and maintains reserves for potential credit losses. Accounts receivable are deemed past due in accordance with the contractual terms of the agreement. Accounts are charged against the allowance for doubtful accounts once collection efforts are unsuccessful. Historically, such losses have been within management’s expectations. Single-source suppliers presently provide the Company with several components. In most cases, if a supplier was unable to deliver these components, the Company believes that it would be able to find other sources for these components subject to any regulatory qualifications, if required. 88 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) Restricted Cash Restricted cash primarily consists of certificates of deposit held as guarantees in connection with customer contracts and corporate leases as well as funds held as guarantees for Value-Added Tax, or VAT obligations in a foreign jurisdiction. Inventories Inventories are stated at the lower of cost (on a first-in, first-out basis) or market value. Excess and obsolete inventories are written down based on historical sales and forecasted demand, as judged by management. Revenue Recognition The Company’s revenue is primarily derived from sales of CyberKnife and TomoTherapy Systems and services, which include post-contract customer support or PCS, installation services, training and other professional services. The Company records its revenues net of any value added or sales tax. In all sales arrangements, the Company recognizes revenues when there is persuasive evidence of an arrangement, the fee is fixed or determinable, collection of the fee is reasonably assured and delivery has occurred. Payments received in advance of system shipment are recorded as customer advances and are recognized as revenue or deferred revenue upon product shipment or installation. The Company assesses the probability of collection based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The Company generally does not request collateral from its customers. If the Company determines that collection is not probable, the Company will defer the fee and recognize revenue upon receipt of cash. The Company frequently enters into sales arrangements that contain multiple elements or deliverables. For sale arrangements that contain multiple elements, the Company allocates the arrangement consideration to each element based on the relative selling price method, whereby the relative selling price of each deliverable is determined using vendor specific objective evidence, or VSOE of fair value, if it exists. VSOE of fair value for each element is based on the Company’s standard rates charged for the product or service when such product or service is sold separately or based upon the price established by the Company’s pricing committee when that product or service is not yet being sold separately. When the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements, which may be due to the Company infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history, the Company attempts to determine the selling price of each element based on third-party evidence of selling price, or TPE, as determined based on competitors’ prices for similar deliverables when sold separately. When the Company is not able to establish selling price using VSOE or TPE, the Company uses its best estimate of selling price, or BESP, in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The Company determines BESP for a product or service by considering multiple factors including, but not limited to, pricing practices, internal costs, geographies and gross margin. The determination of BESP is made through annual analysis of the Company’s pricing practices and adjusted if necessary. The Company has a limited number of software offerings which are not required to deliver its systems’ essential functionality and can be sold separately. The Company accounts for the separate sale 89 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) of its software products in accordance with the applicable guidance for software revenue recognition. The Company’s multiple-element arrangements may also include software deliverables that are subject to the software revenue recognition guidance; and in these cases, the revenue for these multiple- element arrangements is allocated to the software deliverable and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using VSOE, TPE or BESP. The Company regularly reviews VSOE, TPE and BESP for all of its products and services. As the Company’s go-to-market strategies and other factors change, the Company may modify its pricing practices in the future, which may impact the selling prices of systems and services as well as VSOE, TPE and BESP of systems and services. As a result, the Company’s future revenue recognition for multiple element arrangements could differ materially from that recorded in the current period. Product Revenue The majority of product revenue is generated from sales of CyberKnife and TomoTherapy systems. If the Company is responsible for installation, the Company recognizes revenue after installation and acceptance of the system. Otherwise, revenue is generally recognized upon delivery, assuming all other revenue recognition criteria are met. The Company could sell its systems with PCS contracts, installation services, training, and at times, professional services. PCS contracts provide planned and corrective maintenance services, software updates, bug fixes, as well as call-center support. The Company records revenues from sales of systems, product upgrades and accessories to distributors depending on the terms of the distribution agreement as well as terms and conditions executed for each sale, and once all revenue recognition criteria have been met. The Company’s agreements with customers and distributors for system sales generally do not contain product return rights. Certain distributor agreements include parts inventory buy-back provisions upon distributorship termination. The Company accrues an inventory buy-back liability when and if such distributorship termination is expected and the liability can be estimated. Service Revenue Service revenue is generated primarily from PCS (warranty period services and post warranty services), installation services, training, and professional services. PCS revenue is deferred and recognized over the service period. Installation service revenue is recognized concurrent with system revenue. Training revenues are recognized when services are performed, and professional service revenues that are not deemed essential to the functionality of the systems are recognized as such services are performed. Costs associated with service revenue are expensed when incurred, except when those costs are related to system upgrades where revenue recognition has been deferred. In those cases, the incremental costs are deferred and are recognized over the period of revenue recognition. Deferred Revenue and Deferred Cost of Revenue Deferred revenue consists of deferred product revenue and deferred service revenue. Deferred product revenue arises from timing differences between the shipment of product and satisfaction of all 90 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) revenue recognition criteria consistent with the Company’s revenue recognition policy. Deferred service revenue results from the advance payment for services to be delivered over a period of time, usually one year. Deferred cost of revenue consists of the direct costs associated with the manufacturing of units and direct service costs for which the revenue has been deferred in accordance with the Company’s revenue recognition policies. Deferred revenue and associated deferred cost of revenue expected to be realized within one year are classified as current liabilities and current assets, respectively. Customer Advances Customer advances represent payments made by customers in advance of product shipment. Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are depreciated on a straight-line basis over the remaining term of the lease or the estimated useful life of the asset, whichever is shorter. Machinery and equipment are depreciated over five years. Furniture and fixtures are depreciated over four years. Computer and office equipment and computer software are depreciated over three years. Repairs and maintenance costs, which are not considered improvements and do not extend the useful life of the property and equipment, are expensed as incurred. Software Capitalization Costs The Company capitalizes certain costs associated with obtaining or developing internal use software, including external direct costs of material and services. Software development costs relating to assets to be sold in the normal course of business are included in research and development and are expensed as incurred until technological feasibility is established. After technological feasibility is established, material software development costs are capitalized. The capitalized cost is then amortized on a straight-line basis over the estimated product life, or on the ratio of current revenues to total projected product revenue, whichever is greater. To date, the period between achieving technological feasibility, which the Company has defined as the establishment of a working model which typically occurs when the beta testing commences, and the general availability of such software has been short and software development costs qualifying for capitalization have been insignificant. Capitalized software costs are included in property, plant and equipment and amortized beginning when the software project is complete and the assets are ready for their intended use. Impairment of Long-Lived Assets The Company reviews long-lived assets, including intangible assets, property and equipment, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable using pretax undiscounted cash flows. Impairment, if any, is measured as the amount by which the carrying value of a long-lived asset exceeds its fair value. 91 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) Business Combinations The Company allocates the fair value of the purchase consideration of its acquisitions to the tangible assets, liabilities, and intangible assets acquired, including in-process research and development, or IPR&D, based on their estimated fair values. Goodwill represents the excess of acquisition cost over the fair value of tangible and identified intangible net assets of businesses acquired. Transaction costs and costs to restructure the acquired company are expensed as incurred. The operating results of the acquired company are reflected in the Company’s consolidated financial statements after the closing date of the merger or acquisition. Goodwill and Purchased Intangible Assets Goodwill is not amortized, but is evaluated for impairment on an annual basis and when impairment indicators are present. The Company has assessed that it has one operating segment and one reporting unit, and the consolidated net assets, including existing goodwill and other intangible assets, are considered to be the carrying value of the reporting unit. The Company estimates the fair value of the reporting unit based on the Company’s closing stock price on the trading day closest to the annual review date multiplied by the outstanding shares on that date. If the carrying value of the reporting unit is in excess of its fair value, an impairment may exist, and the Company must perform the second step of the analysis, in which the implied fair value of the goodwill is compared to its carrying value to determine the impairment charge, if any. If the estimated fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and no further analysis is required. There was no impairment of goodwill identified in the fiscal years ended June 30, 2015, 2014 and 2013. Purchased intangible assets other than goodwill, including developed technology and distributor license, are amortized on a straight-line basis over their estimated useful lives unless their lives are determined to be indefinite. Purchased intangible assets are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets which range from approximately one to six years. Acquisition-related expenses and restructuring costs are recognized separately from the business combination and are expensed as incurred. Shipping and Handling The Company’s billings for shipping and handling for product shipments to customers are included in cost of products. Shipping and handling costs incurred for inventory purchases are capitalized in inventory and expensed in cost of products. Advertising Expenses The Company expenses the costs of advertising and promoting its products and services as incurred. Advertising expenses were approximately $0.5 million, $0.6 million and $0.7 million for the years ended June 30, 2015, 2014 and 2013, respectively. 92 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) Research and Development Costs Costs related to research, design and development of products are charged to research and development expense as incurred. These costs include direct salaries, benefits, and other headcount related costs for research and development personnel; costs for materials used in research and development activities; costs for outside services and allocated portions of facilities and other corporate costs. The Company has entered into research and clinical study arrangements with selected hospitals, cancer treatment centers, academic institutions and research institutions worldwide. These agreements support the Company’s internal research and development capabilities. Share-Based Compensation The Company issues stock-based compensation awards to employees and directors in the form of stock options, restricted stock units (‘‘RSUs’’), performance stock units (‘‘PSUs’’), market stock units (‘‘MSUs’’) and employee stock purchase plan (‘‘ESPP’’) awards (collectively, ‘‘awards’’). The Company measures and recognizes compensation expense for all stock-based awards based on the awards’ fair value. Share-based compensation for RSUs and PSUs is measured based on the value of the Company’s common stock on the grant date. The Company uses the Monte-Carlo simulation model to estimate the fair value of MSUs. Share-based compensation for employee stock options and ESPP awards are measured on the date of grant using a Black-Scholes option pricing model. Awards vest either on a graded schedule or in a lump sum. The Company determines the fair value of each award as a single award and recognizes the expense on a straight-line basis over the service period of the award, which is generally the vesting period. The exercise price of stock options granted is equal to the fair market value of the Company’s common stock on the date of grant. Stock options expire ten years from the date of grant. Share-based compensation expense for stock options, RSUs, PSUs and the ESPP is based on awards ultimately expected to vest, and the expense is recorded net of estimated forfeitures. The Company recognizes expense for MSUs net of estimated forfeitures and does not adjust the expense for subsequent changes in the expected outcome of the market-based vesting conditions. Loss Contingencies The Company is involved in various lawsuits, claims and proceedings that arise in the ordinary course of business. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Net Loss Per Common Share Basic and diluted net loss per share is computed by dividing net loss attributable to stockholders by the weighted average number of common shares outstanding during the year. 93 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2.

The 3.75% Convertible Senior Notes due August 1, 2016 (the ‘‘3.75% Convertible Notes’’), the 3.50% Convertible Senior Notes due February 1, 2018 (the ‘‘3.50% Convertible Notes’’) and the 3.50% Series A Convertible Notes (the ‘‘3.50% Series A Convertible Notes’’) due February 1, 2018 are included in the calculation of diluted net income per share only if their inclusion is dilutive. For the years ended June 30, 2015, 2014 and 2013, the potentially dilutive shares under the Convertible Notes were excluded from the calculation of diluted net loss per share as their inclusion would have been anti-dilutive.

Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof in cash, the conversion shares underlying the outstanding principal amount of the 3.75% 94 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) Convertible Notes and 3.50% Series A Convertible Notes, totaling approximately 10.6 million shares and 13.2 million shares, respectively, were not included in the potentially diluted share count table above. The Company’s average stock price did not exceed the conversion price of the 3.75% Convertible Notes as of June 30, 2015, 2014 and 2013. The 2.9 million potentially dilutive shares of the 3.50% Series A Convertible Notes included in the table above represent the premium over the principal amount due to the higher average share price. The number of premium shares included in the Company’s diluted share count will vary with fluctuations in the Company’s share price. Higher actual share prices result in a greater number of premium shares. Income Taxes The Company is required to estimate its income taxes in each of the tax jurisdictions in which it operates prior to the completion and filing of tax returns for such periods. This process involves estimating actual current tax expense together with assessing temporary differences in the treatment of items for tax purposes versus financial accounting purposes that may create net deferred tax assets and liabilities. The Company accounts for income taxes under the asset and liability method, which requires, among other things, that deferred income taxes be provided for temporary differences between the tax bases of the Company’s assets and liabilities and their financial statement reported amounts. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses, research and development credit carryforwards, and other deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount the Company believes is more likely than not to be realized. Because of the uncertainty of the realization of the deferred tax assets, the Company has recorded a full valuation allowance against its domestic and certain foreign net deferred tax assets. The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations. Management regularly assesses the Company’s tax positions in light of legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which the Company does business. The Company anticipates that except for $0.4 million in uncertain tax positions that may be reduced related to the lapse of various statutes of limitation, there will be no material changes in uncertain tax positions in the next 12 months. Accumulated Other Comprehensive Income (Loss) The components of comprehensive loss consist of net loss, unrealized gains and losses on available-for-sale investments, changes in foreign currency exchange rate translation and net changes related to a defined benefit pension plan. The unrealized gains and losses on available-for-sale investments, changes in foreign currency exchange rate translation and net changes related to the defined benefit pension plan are excluded from earnings and reported as a component of stockholders’ equity. The foreign currency translation adjustment results from those subsidiaries not using the United States dollar as their functional currency since the majority of their economic activities are primarily denominated in their applicable local currency. Accordingly, all assets and liabilities related to these operations are translated at the current exchange rates at the end of each period. The resulting cumulative translation adjustments are recorded directly to the accumulated other comprehensive loss account in stockholders’ equity. Revenues and expenses are translated at average exchange rates in effect during the period. 95 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2.

The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP including identifying performance 96 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 2. Summary of Significant Accounting Policies (Continued) obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for the Company in its first quarter of fiscal 2018 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. On July 9, 2015, the FASB approved a one year deferral of the effective period. The standard will be effective for the Company for fiscal 2019, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet selected a transition method and is currently evaluating the impact of pending adoption of ASU 2014-09 on its consolidated financial statements and related disclosures. In July 2013, the Financial Accounting Standards Board (‘‘FASB’’) issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 requires that entities with an unrecognized tax benefit and a net operating loss carryforward or similar tax loss or tax credit carryforward in the same jurisdiction as the uncertain tax position present the unrecognized tax benefit as a reduction of the deferred tax asset for the loss or tax credit carryforward rather than as a liability, when the uncertain tax position would reduce the loss or tax credit carryforward under the tax law, thereby eliminating diversity in practice regarding this presentation issue. This new guidance is effective prospectively for annual reporting periods beginning on or after December 15, 2013, although retrospective application is permitted. The Company has implemented this guidance with no impact to the consolidated financial statements or related disclosures. 3.

Financial Instruments The Company considers all highly liquid investments held at major banks, certificates of deposit and other securities with original maturities of three months or less to be cash equivalents. The Company classifies all of its investments as available-for-sale at the time of purchase because it is management’s intent that these investments are available for current operations and includes these investments on its balance sheets as short-term investments. Investments with original maturities longer than three months include commercial paper and investment-grade agency and corporate debt securities. Investments classified as available-for-sale are recorded at fair market value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are recorded based on specific identification of each security’s cost basis. The Company defines fair value 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 on the measurement date. The fair value hierarchy contains three levels of inputs that may be used to measure fair value, as follows: Level 1—Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date. Level 2—Other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including: (cid:129) Quoted prices for similar assets or liabilities in active markets; (cid:129) Quoted prices for identical or similar assets in non-active markets; (cid:129) Inputs other than quoted prices that are observable for the asset or liability; and (cid:129) Inputs that are derived principally from or corroborated by other observable market data. Level 3—Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. 99 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 4.

Business Combinations Fiscal 2013 Acquisition On July 16, 2012, the Company acquired the remaining 90% of the outstanding shares of Morphormics, Inc., or Morphormics, a privately-held developer of medical imaging software based in North Carolina. This acquisition enables the Company to extend auto-contouring capabilities for both the CyberKnife and TomoTherapy systems to improve disease specific workflows. The Company previously held 10% of the outstanding shares of Morphormics, which had a carrying value of zero prior to the acquisition date and was valued at $0.7 million as of the acquisition date based on the fair value of the consideration paid. The acquisition was accounted for as a business combination, and accordingly, Morphormics’ results of operations were included in the consolidated financial statements from July 16, 2012. This transaction was not considered a material business combination, and Company did not incur significant severance or acquisition-related costs in connection with the transaction. 101 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 5.

During its first quarter of fiscal year 2014, the Company determined that certain of these liabilities related to unrecognized tax benefits were recorded in error. The Company evaluated the effects of this error on the financial statements and concluded that the error was not material to any prior annual or interim periods or the current period. In September of 2013, the Company reduced goodwill and accrued liabilities by $1.3 million to remove the liability recorded in error. In fiscal 2015 the Company performed its annual goodwill impairment test. Based on this analysis, the Company determined that there was no impairment to goodwill. The Company will continue to monitor its recorded goodwill for indicators of impairment. 102 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 6.

The Company did not identify any triggering events that would indicate potential impairment of its definite-lived intangible and long-lived assets as of June 30, 2015 and 2014. Amortization expense, excluding impairment charges related to purchased intangible assets was $7.9 million, $8.4 million and $10.4 million for the years ended June 30, 2015, 2014 and 2013, respectively.

Amount $ 7,953 7,568 43 $15,564 7. Investment in CPAC In April 2008, TomoTherapy established an affiliate, CPAC, to develop a compact proton therapy system for the treatment of cancer. Between the date of formation of CPAC through December 2012, the Company and TomoTherapy contributed both cash and intellectual property to CPAC, resulting in a combined equity interest of approximately 15.4% of the outstanding stock of CPAC and approximately 16.3% on a fully diluted basis. As of the Company’s acquisition of TomoTherapy on June 10, 2011, the Company determined that CPAC was a variable interest entity, as CPAC depended on the Company, TomoTherapy and other investors to fund its operations. Under the accounting standards for consolidating variable interest entities, the consolidating investor is the entity with the power to direct the activities of the venture that most significantly impact the venture’s economic performance and with the obligation to absorb losses or the right to receive benefits from the venture that could potentially be significant to the venture. Although the Company and its subsidiary held less than a 50% ownership interest in CPAC, it was determined that the Company met these two characteristics, and therefore, was the primary beneficiary of CPAC. The Company consolidated the results of operations of CPAC from June 10, 2011 to December 21, 2012. 103 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 7. Investment in CPAC (Continued) On December 21, 2012, the Company and CPAC entered into a Purchase Agreement and Release, or Purchase Agreement, which provided for all the equity and debt investments held by the Company in CPAC to be purchased by CPAC for a nominal consideration. In addition, the Company assigned all its rights to the Dielectric Wall Accelerator, or DWA technology licensed from Lawrence Livermore National Security, LLC to CPAC. As a result of the Purchase Agreement, the Company concluded that it was no longer the primary beneficiary of CPAC since it did not have any variable interest in CPAC. In the second quarter of fiscal 2013, the Company deconsolidated CPAC and recorded a loss of $3.4 million, resulting from the write-down of the carrying value of CPAC’s net liabilities, the write-off of receivables from CPAC and the non-controlling interest in CPAC, net of cash consideration received. The results of operations of CPAC, including the loss on deconsolidation of CPAC and the losses attributable to the non-controlling interest recorded for the year ended June 30, 2013has been presented as discontinued operations in the consolidated statements of operations and comprehensive loss. 8. Commitments and Contingencies Operating Lease Agreements and Long-term Debt The Company leases office and manufacturing space under non-cancelable operating leases with various expiration dates through December 2023. Rent expense was $8.0 million, $6.5 million and $8.7 million for the years ended June 30, 2015, 2014 and 2013, respectively. The terms of some of the facility leases provide for rental payments on a graduated scale. For these leases the Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid. The Company is also required to make semi-annual interest payments on the Convertible Notes. See Note 13, Debt, for details. Future minimum lease payments under non-cancelable operating lease agreements and long-term principal and interest on the Convertible Notes as of June 30, 2015 are as follows (in thousands): Year Ending June 30, 2016 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2017 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2018 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2019 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2020 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Commitments and Contingencies (Continued) The Company enters into standard indemnification agreements with its landlords and all superior mortgagees and their respective directors, officers’ agents, and employees in the ordinary course of business. Pursuant to these agreements, the Company will indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the landlords, in connection with any loss, accident, injury, or damage by any third-party with respect to the leased facilities. The term of these indemnification agreements is from the commencement of the lease agreements until termination of the lease agreements. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, historically the Company has not incurred claims or costs to defend lawsuits or settle claims related to these indemnification agreements. The Company has recorded no liability associated with its indemnification agreements as it is not aware of any pending or threatened actions that represent probable losses as of June 30, 2015. Royalty Agreement The Company has an exclusive license agreement with the Wisconsin Alumni Research Foundation, or WARF, to make, use, sell and otherwise distribute products under certain of WARF’s patents anywhere in the world. The Company is required to pay WARF a royalty for each TomoTherapy System sold that includes the licensed technology. The license agreement expires upon expiration of the patents and may be terminated earlier if the Company so elects. WARF has the right to terminate the license agreement if the Company does not meet the minimum royalty obligation of $0.3 million per year, or if the Company commits any breach of the license agreement’s covenants. The Company recorded royalty costs of $0.6 million, $0.7 million and $0.6 million for the years ended June 30, 2015, 2014 and 2013, respectively, which were recorded in cost of revenue or deferred cost of revenue. The Company had accrued liabilities of approximately $0.2 million and $0.1 million at June 30, 2015 and 2014, respectively, related to this agreement. Software License Indemnity Under the terms of the Company’s software license agreements with its customers, the Company agrees that in the event the software sold infringes upon any patent, copyright, trademark, or any other proprietary right of a third-party, it will indemnify its customer licensees against any loss, expense, or liability from any damages that may be awarded against its customer. The Company includes this infringement indemnification in all of its software license agreements and selected managed services arrangements. In the event the customer cannot use the software or service due to infringement and the Company cannot obtain the right to use, replace or modify the license or service in a commercially feasible manner so that it no longer infringes, then the Company may terminate the license and provide the customer a refund of the fees paid by the customer for the infringing license or service. The Company has not recorded any liability associated with this indemnification, as it is not aware of any pending or threatened actions that represent probable losses as of June 30, 2015. Litigation From time to time, the Company is involved in legal proceedings arising in the ordinary course of its business. The Company records a provision for a loss when it believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Currently, management believes the Company does not have any probable and estimable losses related to any current legal proceedings 105 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 8. Commitments and Contingencies (Continued) and claims. Although occasional adverse decisions or settlements may occur, except as described in the matters below, management does not believe that an adverse determination with respect to any of these claims would individually or in the aggregate materially and adversely affect the Company’s financial condition or operating results. For certain legal proceedings, management believes that there is a reasonable possibility that material losses may be incurred; however, the Company is unable to reasonably estimate a range of reasonably possible losses with respect to these matters. Litigation is inherently unpredictable and is subject to significant uncertainties, some of which are beyond the Company’s control. Should any of these estimates and assumptions change or prove to have been incorrect, the Company could incur significant charges related to legal matters that could have a material impact on its results of operations, financial position and cash flows. Rotary Systems On April 28, 2011, a former supplier to TomoTherapy, Rotary Systems Incorporated, (‘‘Rotary Systems’’), filed suit in Minnesota state court, Tenth Judicial District, Anoka County, against TomoTherapy alleging misappropriation of trade secrets, as well as several other counts alleging various theories of injury. Rotary Systems alleges TomoTherapy misappropriated Rotary Systems’ trade secrets pertaining to a component previously purchased from Rotary Systems, which component TomoTherapy now purchases from a different supplier. The suit alleges TomoTherapy improperly supplied the alleged trade secrets to its present supplier, Dynamic Sealing Technologies Inc. (also a named defendant in the suit). Rotary Systems has made an unspecified claim for damages of greater than $50,000. TomoTherapy moved to dismiss the case and, on August 29, 2011, the court granted the motion to dismiss with respect to all counts other than the count alleging misappropriation of trade secrets. On May 21, 2012, the court gave Rotary Systems sixty days to identify the alleged trade secrets with specificity or face dismissal of its claim with prejudice. The court held a hearing on September 20, 2012 to review Rotary Systems’ amended complaint. TomoTherapy filed a motion for summary judgment on the trade secret claim, the court ruled in favor of TomoTherapy on December 5, 2013, and Rotary Systems appealed. On December 22, 2014, the Minnesota Court of Appeals reversed the district court’s dismissal of Rotary Systems’ trade secrets claim and remanded it to the district court but affirmed the dismissal of Rotary Systems’ other claims. Sarif Biomedical Patent Litigation On January 28, 2013, Sarif Biomedical filed a patent infringement complaint against the Company in the U.S. District Court for the District of Delaware. The complaint alleges the Company’s CyberKnife System directly infringes U.S. Patent No. 5,755,725 and seeks unspecified monetary damages for the alleged infringement. Accuray filed an answer to the complaint in March 2013. The parties have exchanged initial discovery requests and responses. The court issued a scheduling order on April 29, 2014. Accuray made its first document production on May 30, 2014. On January 7, 2015, the parties entered into a written settlement agreement resolving the lawsuit. This settlement didn’t have a material impact on the results of operations for the three or nine months ended March 31, 2015. On January 13, 2015, the court entered an order dismissing the case and all claims with prejudice. Cowealth Medical On February 27, 2014, Cowealth Medical Holding Co., Ltd. (‘‘Cowealth’’), Accuray’s former distributor in China, submitted a request for binding arbitration with the International Chamber of 106 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 8. Commitments and Contingencies (Continued) Commerce International Court of Arbitration (‘‘ICC’’) alleging, among other matters, that Accuray breached its distributor agreement with Cowealth by wrongfully terminating Cowealth as its distributor and misappropriated certain of Cowealth’s confidential information. Cowealth is seeking damages of approximately $170.0 million and injunctive relief. Accuray has filed counterclaims for damages of approximately $35.0 million. Accuray’s answer and counterclaim were submitted to the ICC on May 12, 2014, and Cowealth served its reply on June 27, 2014. A hearing was held in Hong Kong between January 26, 2015 and February 6, 2015. The parties filed closing submissions and reply closing submissions in March 2015. The Company expects the arbitrator to render a decision sometime between October 2015 and February 2016. We are unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. 9. Stockholders’ Equity At June 30, 2015, the Company had 13.2 million and 21.6 million shares of common stock reserved for future issuance to the holders of the 3.75% Convertible Senior Notes and 3.50% Convertible Senior Notes (including Series A Convertible Senior Notes), respectively, and had 12.2 million shares of common stock reserved for issuance under the stock incentive plans and the employee stock purchase plan. 10. Stock Incentive Plan and Employee Stock Purchase Plan As of June 30, 2015, the Company had two outstanding stock incentive plans: the 2007 Stock Incentive Plan, or the 2007 Plan; and the 1998 Stock Incentive Plan, or the1998 Plan. The 2007 Plan permits the granting of stock options, restricted stock awards, or RSAs and restricted stock units, or RSUs. The vesting of RSUs under the 2007 Plan may be time-based (over the requisite service period), performance-based, or PSUs or market-based, or MSUs. Only employees of the Company are eligible to receive incentive stock options. Non-employees may be granted non-qualified options. Stock options granted under the 2007 Plan have an exercise price of at least 100% of the fair market value of the underlying stock on the grant date and no less than 85% of the fair value for non-qualified stock options. The stock options have 10 year contractual terms and generally become exercisable for 25% of the option shares one year from the date of grant and then ratably over the following 36 months. Time-based RSUs generally vest 25% of the share units covered by the grant on each of the first through fourth anniversaries of the date of the grant. However, certain of the outstanding RSUs vest 50% upon the first anniversary year of the grant date, and 50% upon the second anniversary year of the grant date. The Board of Directors has the discretion to use different vesting schedules. As of June 30, 2015, the 1998 Plan continued to remain in effect; however, the Company can no longer make equity awards under the plan. 107 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 10.

The amount capitalized for the year ended June 30, 2015 was immaterial. Stock Options The Company did not grant any stock options in the years ended June 30, 2015 and 2014. The Company used the Black-Scholes option pricing model to measure the fair value of stock options grants.

The total intrinsic value of options exercised in the years ended June 30, 2015, 2014 and 2013 was approximately $1.4 million, $3.8 million and $4.5 million, respectively. During the years ended June 30, 2015, 2014 and 2013, the Company recognized $1.1 million, $1.7 million and $2.9 million, respectively, of share-based compensation expense for stock options granted to employees. The weighted average fair value of options granted was $3.48 per share for the year ended June 30, 2013. Tax benefits from tax deductions for exercised options and disqualifying dispositions in excess of the deferred tax asset attributable to stock compensation costs for such options are credited to additional paid-in capital. Realized excess tax benefits related to stock options exercises was zero for each of the years ended June 30, 2015, 2014 and 2013. As of June 30, 2015, there was approximately $1.0 million of unrecognized compensation cost, net of estimated forfeitures, related to unvested stock options, which is expected to be recognized over a weighted average period of 1.26 years. 109 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 10.

The Company recognized $0.3 million of share-based compensation expense during the year ended June 30, 2013, related to RSAs assumed in connection with the acquisition of TomoTherapy. The expense recognized in fiscal 2015 and 2014 was immaterial. Performance Stock Units During fiscal 2012, the Compensation Committee approved the grant of 1.0 million PSUs to certain employees of the Company. The PSUs were cancelled in fiscal 2014 as it was determined that the Company did not achieve the requisite performance targets. The Compensation Committee approved the grant of 20,000, 70,000 and 36,000 PSUs to select employees of the Company in the years ended June 30, 2015, 2014 and 2013, respectively. Of these PSUs, 25,000, 25,000 and 18,000 vested in the years ended June 30, 2015, 2014 and 2013, respectively, due to the achievement of the requisite performance targets while zero, 38,000 and zero were cancelled in the years ended June 30, 2015, 2014 and 2013, respectively. The Company recognized $0.2 million and $0.1 million of share-based compensation expense, net of estimated forfeitures, related to PSUs during the years ended June 30, 2015 and 2014, respectively. The expense recognized during the year ended June 30, 2013 was immaterial. Market Stock Units The Compensation Committee approved the performance equity program, referred to as the market stock unit program, or MSU program, in October 2012. The Company’s MSU Program uses the Russell 2000 index as a performance benchmark and requires that the Company’s total stockholder return match or exceed that of the Russell 2000. Based on a sliding scale of how much the Company’s total stockholder return outperforms the Russell 2000 benchmark, the participating executives can earn up to a maximum of 150% of the target number of shares over two measurement periods. The Company uses a Monte-Carlo simulation to calculate the fair value of the award on the grant date. The Company recognized $3.4 million, $1.8 million and $0.3 million of share-based compensation expense, net of estimated forfeitures, related to MSUs during the years ended June 30, 2015, 2014 and 2013, respectively. The weighted average grant date fair value per share of MSUs was $6.64, $7.18 and $5.39 for the years ended June 30, 2015, 2014 and 2013, respectively. As of June 30, 2015, there was approximately $2.2 million of unrecognized compensation cost, net of estimated forfeitures, related to MSUs. There were no vested MSUs and 0.2 million MSUs cancelled in fiscal 2015 as the performance targets were not certified by the Compensation Committee. Subsequent to fiscal 2015 year-end, the 111 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 10. Stock Incentive Plan and Employee Stock Purchase Plan (Continued) Compensation Committee certified the achievement of the performance targets for 0.4 million shares related to the first tranche of the fiscal 2014 grants which achieved 132% of target. There were no vested MSUs and 0.2 million of MSUs were cancelled in fiscal 2014 as the performance targets were not achieved for the first measurement period. Assuming 100% performance target will be achieved, 0.6 million and 0.5 million of MSUs will vest by the end of fiscal 2016 and 2017, respectively. Employee Stock Purchase Plan Under the Company’s 2007 Employee Stock Purchase Plan, or ESPP, qualified employees are permitted to purchase the Company’s common stock at 85% of the lower of the fair market value of the common stock on the commencement date of each offering period or the fair market value on the specified purchase date. The ESPP is deemed compensatory and compensation costs are accounted for under ASC 718, Stock Compensation. Employees’ payroll deductions may not exceed 10% of their salaries. Employees may purchase up to 2,500 shares per period provided that the value of the shares purchased in any calendar year may not exceed $25,000, as calculated pursuant to the purchase plan. The Company estimates the fair value of ESPP shares at the date of grant using the Black-Scholes option pricing model.

For the years ended June 30, 2015, 2014 and 2013, the Company recognized $1.3 million, $1.3 million and $1.3 million, respectively, of compensation expense related to its ESPP. The Company issued 0.7 million shares under the ESPP in fiscal 2015 and 2014, respectively, at a weighted average price per share of $5.61 and $5.44, respectively. As of June 30, 2015, total unrecognized compensation cost related to the ESPP plan was $0.6 million, which the Company expects to recognize over a weighted average period of 0.6 years. 112 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 11.

It is not practicable to determine the income tax liability that might be incurred if these earnings were to be repatriated to the U.S. As of June 30, 2015 the Company had approximately $329.6 million and $157.5 million in federal and state net operating loss carryforwards, respectively. The federal and state carryforwards expire in varying amounts beginning in 2019 for federal and 2016 for state purposes. Such net operating loss carryforwards include excess tax benefits from employee stock option exercises which, in accordance with guidance for income tax accounting, have not been recorded within the Company’s deferred tax asset balances. The Company will record approximately $3.9 million as a credit to additional paid-in capital as and when such excess benefits are ultimately realized. In addition, as of June 30, 2015, the Company had federal and state research and development tax credits of approximately $16.3 million and $16.5 million, respectively. The federal research credits will begin to expire in 2019, the California research credits have no expiration date, and the other state research credits began to expire in 2016. Utilization of the Company’s net operating loss and credit carryforwards is subject to annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue 114 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 11. Income Taxes (Continued) Code and similar state provisions. The acquisition of TomoTherapy and the resulting Section 382 limitation should not result in the expiration of net operating losses or credits due to the Section 382 limitation. Based on the available objective evidence and history of losses, the Company has established a 100% valuation allowance against the combined domestic net deferred tax assets of Accuray and TomoTherapy due to uncertainty surrounding the realization of such deferred tax assets.

Management regularly assesses the Company’s tax positions in respect to legislative, bilateral tax treaty, regulatory and judicial developments in the countries in which the Company does business. The reduction in prior years tax positions primarily relates to lapses of applicable statutes of limitations. The Company anticipates that except for $0.4 million in uncertain tax positions that may be reduced related to the lapse of various statutes of limitation, there will be no material changes in uncertain tax positions in the next 12 months. As of June 30, 2015, the amount of gross unrecognized tax benefits was $17.0 million of which $10.5 million would affect the Company’s effective tax rate if realized. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of June 30, 2015 and 2014, the Company had approximately $0.9 million and $0.7 million, respectively, of accrued interest and penalties related to uncertain tax positions. The Company files income tax returns in the United States federal, various states and foreign jurisdictions. Due to attributes being carried forward and utilized during open years, the statute of limitations remains open for the U.S. federal jurisdiction and domestic states for tax years from 1999 and forward. The material foreign jurisdictions are France, Switzerland, and Japan, whose tax years remain open from 2011, 2009, and 2009, respectively. The Company is also subject to periodic examination of its income tax returns by the Internal Revenue Service (IRS) and other tax authorities, and in some cases the Company has received additional tax assessments which have not been significant. Currently, the Company is under audit by the German tax authorities which is not expected to have a material impact on the results of operations. 115 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 12.

Debt 3.75% Convertible Senior Notes due August 2016 On August 1, 2011, the Company issued the 3.75% Convertible Notes to certain qualified institutional buyers or QIBs. The 3.75% Convertible Notes were offered and sold to the QIBs pursuant to Rule 144A under the Securities Act of 1933, as amended or Rule 144A. The net proceeds from the $100 million offering, after deducting the initial purchaser’s discount and commission and the related offering costs, were approximately $96.1 million. The offering costs and the initial purchaser’s discount and commission (which are recorded in Other Assets) are both being amortized to interest expense using the effective interest method over five years. The 3.75% Convertible Notes bear interest at a rate of 3.75% per year, payable semi-annually in arrears in cash on February 1 and August 1 of each year, beginning on February 1, 2012. The 3.75% Convertible Notes will mature on August 1, 2016, unless earlier repurchased, redeemed or converted. The 3.75% Convertible Notes were issued under an Indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.75% Convertible Notes may convert their 3.75% Convertible Notes at any time on or after May 1, 2016 until the close of business on the business day immediately preceding the maturity date. Prior to May 1, 2016, holders of the 3.75% Convertible Notes may convert their 3.75% Convertible Notes only under the following circumstances: (1) during any calendar quarter after the calendar quarter ending September 30, 2011, and only during such calendar quarter, if the closing sale price of the Company’s common stock for each of 20 or more trading days in the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading-day period (such five consecutive trading-day period, the ‘‘Note Measurement Period’’) in which the trading price per $1,000 principal amount of 3.75% Convertible Notes for each trading day of that Note Measurement Period was equal to or less than 98% of the product of the closing sale price of shares of the Company’s common stock and the applicable conversion rate for such trading day; (3) if the Company calls any or all of the 3.75% Convertible Notes for redemption, at any time prior to the close of business on the business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate transactions as described in the Indenture. Upon conversion by holders of the 3.75% Convertible Notes, the Company will have the right to pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof, at the Company’s election. At any time on or prior to the 33rd business day immediately preceding the maturity date, the Company may irrevocably elect to (a) deliver solely shares of common stock of the Company in respect of the Company’s conversion 116 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 13. Debt (Continued) obligation or (b) pay cash up to the aggregate principal amount of the 3.75% Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 3.75% Convertible Notes being converted. The initial conversion rate is 105.5548 shares of the Company’s common stock per $1,000 principal amount of 3.75% Convertible Notes (which represents an initial conversion price of approximately $9.47 per share of the Company’s common stock). The conversion rate, and thus the conversion price, are subject to adjustment as further described below. Holders of the 3.75% Convertible Notes who convert their 3.75% Convertible Notes in connection with a ‘‘make-whole fundamental change,’’ as defined in the Indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, in the event of a ‘‘fundamental change,’’ as defined in the Indenture, holders of the 3.75% Convertible Notes may require the Company to purchase all or a portion of their 3.75% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of 3.75% Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. Prior to the maturity date, the Company may redeem for cash all or a portion of the 3.75% Convertible Notes if the closing sale price of its common stock exceeds 130% of the applicable conversion price (the initial conversion price is approximately $9.47 per share of common stock) of such 3.75% Convertible Notes for at least 20 trading days during any consecutive 30 trading-day period (including the last trading day of such period). In accordance with ASC 470-20, the Company separately accounts for the liability and equity conversion components of the 3.75% Convertible Notes. The principal amount of the liability component of the 3.75% Convertible Notes was $75.9 million as of the date of issuance based on the present value of its cash flows using a discount rate of 10%, our approximate borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. The carrying value of the equity conversion component was $24.1 million. A portion of the initial purchaser’s discount and commission and the offering costs totaling $0.9 million was allocated to the equity conversion component. The liability component is being accreted to the principal amount of the 3.75% Convertible Notes using the effective interest method over five years. 3.50% Convertible Senior Notes due February 2018 In February 2013, the Company issued $115.0 million aggregate principal amount of its 3.50% Convertible Notes to certain QIBs. The 3.50% Convertible Notes were offered and sold to the QIBs pursuant to Rule 144A. The net proceeds from the offering, after deducting the initial purchaser’s discount and commission and the related offering costs, were approximately $110.5 million. The offering costs and the initial purchaser’s discount and commission (which are recorded in Other Assets) are both being amortized to interest expense using the effective interest method over five years. The 3.50% Convertible Notes bear interest at a rate of 3.50% per year, payable semi-annually in arrears in cash on February 1 and August 1 of each year, which began on August 1, 2013. The 3.50% Convertible Notes will mature on February 1, 2018, unless earlier repurchased, redeemed or converted. In April 2014, through a series of transactions, the Company refinanced approximately $70.3 million aggregate principal amount of the 3.50% Convertible Notes with approximately 117 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 13. Debt (Continued) $70.3 million aggregate principal amount of the Company’s new 3.50% Series A Convertible Senior Notes due 2018 (the ‘‘3.50% Series A Convertible Notes’’). The 3.50% Convertible Notes were issued under an Indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.50% Convertible Notes may convert their 3.50% Convertible Notes at any time until the close of business on the business day immediately preceding the maturity date. The 3.50% Convertible Notes are convertible, as described below into common stock of the Company at an initial conversion rate equal to 187.6877 shares of common stock per $1,000 principal amount of the 3.50% Convertible Notes, which is equivalent to a conversion price of approximately $5.33 per share of common stock, subject to adjustment. Holders of the 3.50% Convertible Notes who convert their 3.50% Convertible Notes in connection with a ‘‘make-whole fundamental change’’, as defined in the Indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, in the event of a ‘‘fundamental change,’’ as defined in the Indenture, holders of the 3.50% Convertible Notes may require the Company to purchase all or a portion of their 3.50% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of 3.50% Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In accordance with guidance in ASC 470-20, Debt with Conversion and Other Options and ASC 815-15, Embedded Derivatives, the Company determined that the embedded conversion components of the 3.50% Convertible Note do not require bifurcation and separate accounting. The remaining $44.7 million principal amount of the 3.50% Convertible Note has been recorded in Long-term Debt on the consolidated balance sheet as of June 30, 2015. 3.50% Series A Convertible Senior Notes due February 2018 On April 17, 2014, the Company entered into note exchange agreements with certain holders (the ‘‘Participating Holders’’) of the 3.50% Convertible Notes to refinance approximately $70.3 million aggregate principal amount of the 3.50% Convertible Notes with approximately $70.3 million aggregate principal amount of the 3.50% Series A Convertible Notes. Pursuant to the note exchange agreements, the Company also paid the Participating Holders an aggregate of approximately $0.4 million in cash in connection with such transactions. The principal amount of 3.50% Convertible Notes refinanced for each $1,000 principal amount of the 3.50% Series A Convertible Notes was $1,000 and the amount in cash paid per $1,000 principal amount of such 3.50% Convertible Notes delivered was determined in individual negotiations between the Company and each Participating Holder. The Series A Convertible Notes have the same interest rate, maturity and other terms as the 3.50% Convertible Notes, except that the 3.50% Series A Convertible Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s option. The 3.50% Series A Convertible Notes were issued under an Indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.50% Series A Convertible Notes may convert their Securities at any time on or after November 1, 2017 until the close of business on the business day immediately preceding the maturity date. Prior to November 1, 2017, holders of the 3.50% Series A Convertible Notes may convert their Securities only under the following circumstances: (1) during any calendar quarter after the calendar quarter ending September 30, 2014, and only during such calendar quarter, if the closing sale price of the Company’s common stock for each of 20 or more trading days in the 30 consecutive trading days ending on the 118 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 13. Debt (Continued) last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading-day period (such five consecutive trading-day period, the ‘‘Note Measurement Period’’) in which the trading price per $1,000 principal amount of 3.50% Series A Convertible Notes for each trading day of that Securities Measurement Period was equal to or less than 98% of the product of the closing sale price of shares of the Company’s common stock and the applicable conversion rate for such trading day; or (3) upon the occurrence of specified corporate transactions as described in the Indenture. Upon conversion by holders of the 3.50% Series A Convertible Notes, the Company will have the right to pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof, at the Company’s election. At any time on or prior to the 17th business day immediately preceding the maturity date, the Company may irrevocably elect to (a) deliver solely shares of common stock of the Company in respect of the Company’s conversion obligation or (b) pay cash up to the aggregate principal amount of the 3.50% Series A Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of common stock of the Company or a combination thereof in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 3.50% Series A Convertible Notes being converted. The initial conversion rate is 187.6877 shares of the Company’s common stock per $1,000 principal amount of 3.50% Series A Convertible Notes (which represents an initial conversion price of approximately $5.33 per share of the Company’s common stock). The conversion rate, and thus the conversion price, are subject to adjustment as further described below. Holders of the 3.50% Series A Convertible Notes who convert their Notes in connection with a ‘‘make-whole fundamental change’’, as defined in the Indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, in the event of a ‘‘fundamental change,’’ as defined in the Indenture, holders of the 3.50% Series A Convertible Notes may require the Company to purchase all or a portion of their 3.50% Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 3.50% Series A Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In accordance with Accounting Standards Codification, or ASC 470-20, Debt with Conversion and Other Options, the Company separately accounts for the liability and equity conversion components of the 3.50% Series A Convertible Notes. The principal amount of the liability component of the 3.50% Series A Convertible Notes was $62.5 million as of the date of issuance based on the present value of its cash flows using a discount rate of 7%, our approximate borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. The carrying value of the equity conversion component was $7.9 million. In addition, the portion of the cash amount paid to the Participating Holders totaling $0.4 million was allocated to the debt discount with the remaining $47,000 to the equity component. The liability component is being accreted to the principal amount of the 3.50% Series A Convertible Notes using the effective interest method through the maturity in February 2018. 119 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 13.

Defined Benefit Pension Obligation The Company has established a defined pension plan for its employees in the Switzerland subsidiary. The plan provides benefits to employees upon retirement, death or disability. The Company uses June 30 as the year-end measurement date for this plan. The unfunded liability of $1.7 million was recognized in long-term other liabilities in the accompanying balance sheet as of June 30, 2015. Actuarial loss of $1.0 million was recognized in other comprehensive income (loss) in fiscal 2015. 120 Accuray Incorporated Notes to Consolidated Financial Statements (Continued) 16.

In the year ended June 30, 2013, the Company recorded restructuring charges of $9.1 million, included in general and administrative expenses in the consolidated statements of operations and comprehensive loss. Restructuring expenses during the year ended June 30, 2013 were comprised of the following: (cid:129) Lease termination charge of $1.4 million, net of estimated sub-lease income, for the remaining lease obligations on an office facility that the Company vacated, and a charge of $0.3 million related to the disposition of certain fixed assets and the write-down of leasehold improvements at this office facility. (cid:129) Severance-related charges of $7.4 million primarily related to the terminations of the Company’s former Chief Executive Officer and Chief Operating Officer and a 13% reduction in its worldwide headcount. 17.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. Item 9A. CONTROLS AND PROCEDURES (a) Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) as of June 30, 2015. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of the end of the period covered by our Annual Report on Form 10-K, our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. (b) Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. Under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, management conducted an evaluation of the effectiveness of our internal control over financial reporting based upon the guidelines established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (‘‘COSO’’) 2013. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of June 30, 2015, based upon the guidelines established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (‘‘COSO’’) 2013. Grant Thornton LLP, an independent registered public accounting firm, has audited the consolidated financial statements included in this Annual Report on Form 10-K and, as part of the audit, has issued a report, included in Item 8 of this Annual Report on Form 10-K, on the effectiveness of our internal control over financial reporting as of June 30, 2015. (c) Changes in Internal Control over Financial Reporting Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated any changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2015, and has concluded that there was no change during such quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. Inherent Limitations of Internal Controls Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a 122 risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Item 9B. OTHER INFORMATION None. 123 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors and Stockholders Accuray Incorporated We have audited the internal control over financial reporting of Accuray Incorporated (a Delaware Corporation) and subsidiaries (the ‘‘Company’’) as of June 30, 2015, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2015, based on criteria established in the 2013 Internal Control— Integrated Framework issued by COSO. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended June 30, 2015, and our report dated August 28, 2015 expressed an unqualified opinion on those financial statements. /s/ GRANT THORNTON LLP San Francisco, California August 28, 2015 124 PART III Item 10.
