General We discover and commercialize genetic tests that determine the risk of developing disease, assess the risk of disease progression, and guide treatment decisions across medical specialties where critical genetic insights can significantly improve patient care and lower healthcare costs. Since our founding in 1992, we have performed tests for approximately five million patients. Our mission and purpose is to advance health and well-being for all, empower individuals with vital genetic insights and enable healthcare providers to better detect, treat and prevent disease. We are currently developing and executing upon a strategic transformation plan that is focused on the following strategic priorities: (1) put patients and customers first; (2) build new tech-enabled commercial capabilities; (3) elevate core products to their full potential; and (4) create new avenues for growth. In connection with these strategic priorities, we are focusing our efforts on our Hereditary Cancer, Tumor Profiling, Prenatal and Pharmacogenomics products and, as described below, have divested certain non-core assets and businesses. We intend to execute on our transformation plan by prioritizing product innovation, research and technology initiatives, strategic collaborations and investments, and defining and deploying a customer-centric technology-enabled commercial model. We believe that by focusing on these strategic priorities, we will be able to reduce complexity and cost, improve our financial performance, build a more effective and cost-efficient sales model, and enhance our reimbursement and revenue cycle capabilities. In addition, we believe we can accelerate growth as we invest in innovation, research and partnerships, develop capabilities to support our sales team with new digital tools and add more direct-to-consumer engagement, and build commercial capabilities to support new products and acquisitions. Business Updates During the quarter endedSeptember 30, 2021 , we continued to see improvement in business fundamentals for our diagnostic products which have been affected by the COVID-19 pandemic. We have also made the following recent announcements: •OnSeptember 13, 2021 , we completed the sale of select operating assets and intellectual property, including the Vectra® test, from the Myriad Autoimmune business unit (the "Autoimmune Business Transaction") to Laboratory Corporation of America Holdings for cash consideration of$150.0 million .
•On
•OnAugust 2, 2021 , we launched a new version of the myRisk Hereditary Cancer Test which allows women of all ancestries to receive a personalized polygenic breast cancer risk assessment for the first time.

-------------------------------------------------------------------------------- Table of Contents The Cost of molecular diagnostic testing as a percentage of revenue decreased from 31.2% to 27.7% during the nine months endedSeptember 30, 2021 compared to the same period in the prior year. The decrease was primarily driven by the increase in revenue from higher test volumes during the period as the same period from the prior year was impacted by COVID-19; thus, costs decreased as a percentage of revenue as revenue from increases in test volumes outpaced personnel and materials costs to perform the tests. The cost of pharmaceutical and clinical services decreased compared to the same period in the prior year due to the sale ofMyriad RBM, Inc. that was completed onJuly 1, 2021 . Research and Development Expense Nine months ended September 30, (in millions) 2021 2020 Change R&D expense $ 61.4$ 54.7 $ 6.7 R&D expense as a % of total revenue 11.6 % 13.6 % Research and development expense for the nine months endedSeptember 30, 2021 increased compared to the same period in the prior year primarily due to increases in costs incurred in the current period as part of the Company's strategic transformation initiatives, increases in lab expenses, and increases in compensation costs as a result of employee bonus reductions in the prior period stemming from the significant impact of COVID-19 on the Company's financial results.

Table of Contents
Liquidity and Capital Resources Our primary sources of liquidity are our cash, cash equivalents and marketable investment securities, our cash flows from operations, our cash flows from investing activities, and, in certain circumstances as discussed below, amounts available for borrowing under our Amended Facility. Our capital deployment strategy focuses on use of resources in the key areas of research and development and acquisitions. We believe that investing organically through research and development and acquisitively to support business strategy provides the best return on invested capital. During the three months endedSeptember 30, 2021 , our liquidity increased$346.6 million from the combined proceeds from the sales ofMyriad RBM, Inc. and the Myriad Autoimmune business. The cash generated from these divestitures provides us with additional liquidity as we seek out strategic opportunities for capital deployment. We believe that our existing capital resources will be sufficient to meet our current and projected operating requirements for the foreseeable future. In addition, our capital resources and cash on hand may be used for acquisitions or other strategic investments. All remaining borrowings under our Amended Facility, which matures onJuly 31, 2023 , were repaid onJuly 30, 2021 using cash generated from our recent divestitures. Our available capital resources, however, may be consumed more rapidly than currently expected, and we may need or want to raise additional financing. We may not be able to secure such financing in a timely manner or on favorable terms, if at all. In addition, we are subject to financial covenants as part of our Amended Facility that could limit our ability to incur additional indebtedness. Without additional funds, we may be forced to delay, scale back or eliminate some of our sales and marketing efforts, research and development activities, or other operations, and potentially delay development of our diagnostic tests in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals could be adversely affected. The Amended Facility restricts our ability to make future borrowings if unrestricted cash, cash equivalents and marketable securities exceed$150.0 million , unless such borrowings are used in connection with certain permitted acquisitions. Unrestricted cash, cash equivalents and marketable securities totaled$413.6 million as ofSeptember 30, 2021 . Our revolving commitment amount is$250.0 million as ofSeptember 30, 2021 . As the Company's total unrestricted cash, cash equivalents, and marketable securities exceeded$150.0 million as ofSeptember 30, 2021 , we will be unable to make future borrowings unless related to a permitted acquisition. In addition, following the expiration of the waiver of the leverage ratio and interest coverage ratio covenants, which waiver is effective untilMarch 31, 2022 , our ability to borrow under the Amended Facility will be limited if we are unable to comply with those financial covenants. From time to time, we enter into purchase commitments or other agreements that may materially impact our liquidity position in future periods. InApril 2021 , a non-cancelable operating lease for our new corporate headquarters inSalt Lake City, Utah , commenced with a lease term of 15 years and total future lease payments of approximately$67.0 million as ofSeptember 30, 2021 . In addition, we have accrued$48.0 million for a potential settlement of the qui tam lawsuit againstCrescendo Bioscience, Inc. and the Company, which is included in accrued liabilities in our Condensed Consolidated Balance Sheet. 31 -------------------------------------------------------------------------------- Table of Contents Due to the continuing evolving global situation from the COVID-19 pandemic, including the emergence of the more highly transmissible Delta coronavirus variant and its impact on the ongoing recovery from the COVID-19 pandemic, it is not possible to predict whether unanticipated consequences of the pandemic are reasonably likely to materially affect our liquidity and capital resources in the future. Because of the specialized scientific nature of our business, we are highly dependent upon our ability to attract and retain qualified management, scientific, and technical personnel. Competition and compensation for such personnel and other qualified personnel rose as employment vacancies surged during the nine months endedSeptember 30, 2021 , and job applicants are often seeking a more flexible work arrangement over the long term as a condition of employment.President Biden's administration is in the process of implementing a mandate requiring companies with 100 or more employees to require full COVID-19 vaccination or regular testing for COVID-19 as a condition of employment. The mandate could increase already elevated employment vacancies. In addition, any future federal or state regulations that could require us to mandate full COVID-19 vaccinations for our employees, or any future decision on our part to voluntarily require our employees to receive a COVID-19 vaccine, could impact our ability to hire and retain employees. Loss of the services of or failure to recruit additional key management, scientific and technical personnel and other qualified personnel who are necessary to operate our business would adversely affect our research and development programs and molecular diagnostic business. Additionally, disruptions to our supply chain as a result of COVID-19 could cause shortages of critical materials required to conduct our business, which may have a material adverse effect on our business as a whole. In addition, inflation, led by supply constraints, federal stimulus funding, increases to household savings, and the sudden macroeconomic shift in activity levels arising from the loosening or removal of many government restrictions and the broader availability of COVID-19 vaccines, has had, and may continue to have, an impact on the labor costs we incur to attract and retain qualified personnel, costs to generate sales and produce diagnostic testing results, and costs of lab supplies. The following table represents the balances of cash, cash equivalents and marketable investment securities: September 30, December 31, (in millions) 2021 2020 Change Cash and cash equivalents$ 295.2 $ 117.0 $ 178.2 Marketable investment securities 70.9 33.7 37.2 Long-term marketable investment securities 47.5 21.0 26.5 Cash, cash equivalents and marketable investment securities$ 413.6
The increase in cash, cash equivalents, and marketable investment securities was primarily driven by$379.1 million in total cash consideration from the sale ofMyriad RBM, Inc. , select assets of the Myriad Autoimmune business unit, and the Myriad myPath, LLC laboratory, the receipt of an$89.6 million U.S. federal tax refund in the quarter endedMarch 31, 2021 , and proceeds of$90.0 million from the exercise of stock options, partially offset by$226.4 million in repayments of the Company's revolving credit facility during the nine months endedSeptember 30, 2021 and$10.5 million in transaction expenses related to the foregoing divestitures, as well as by cash used in operating activities as part of our normal course of business.
