Overview
We are a growing cancer genomics company transforming the development of next-generation therapies by providing more comprehensive molecular data about each patient's cancer and immune response. We designed our NeXT Platform to adapt to the complex and evolving understanding of cancer, providing our biopharmaceutical customers with information on all of the approximately 20,000 human genes, together with the immune system, in contrast to many cancer panels that cover roughly 50 to 500 genes. In parallel with the development of our platform technology, we have also provided population sequencing services under contract with theU.S. Department of Veterans Affairs (the "VA") Million Veteran Program (the "VA MVP"), which has enabled us to innovate, scale our operational infrastructure, and achieve greater efficiencies in our lab. We are also developing a complementary liquid biopsy assay that analyzes all of the approximately 20,000 human genes versus the more narrowly focused liquid biopsy assays that are currently available. By combining technological innovation, operational scale, and regulatory differentiation, our NeXT Platform is designed to help our customers obtain new insights into the mechanisms of response and resistance to therapy as well as new potential therapeutic targets. Our platform enhances the ability of biopharmaceutical companies to unlock the potential of conducting translational research in the clinic rather than with pre-clinical animal models or cancer cell lines. We also announced inJanuary 2020 a diagnostic based on our NeXT Platform that we envision being used initially by both leading clinical cancer centers as well as biopharmaceutical companies. We generated revenues of$65.2 million ,$37.8 million , and$9.4 million for the years endedDecember 31, 2019 , 2018, and 2017, respectively. In 2019, 67% of our revenues were generated from theU.S. Department of Veterans Affairs (the "VA") Million Veteran Program (the "VA MVP") as compared to 49% in 2018. Non-VA MVP revenues increased by 13% in 2019 compared to 2018. We also incurred net losses of$25.1 million ,$19.9 million and$23.6 million for the years endedDecember 31, 2019 , 2018, and 2017, respectively. As ofDecember 31, 2019 , we had$128.3 million in cash and cash equivalents, and short-term investments. From inception throughDecember 31, 2019 , we have funded our operations primarily through cash from operations, redeemable convertible preferred stock issuances, debt issuances, and proceeds from our initial public offering. We expect that our existing cash and cash equivalents, and short-term investments will provide sufficient funds to sustain operations through at least the next 12 months. We have based these estimates on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect.
Factors Affecting Our Performance
We believe there are several important factors that have impacted, and that we expect will continue to impact, our operating performance and results of operations, including:
• The continued development of the market for genomic-based tests. Our
performance depends on the willingness of biopharmaceutical customers to
continue to seek more comprehensive molecular information to develop more
efficacious cancer therapies. 59
--------------------------------------------------------------------------------
• Increasing adoption of our products and solutions by existing customers.
Our performance depends on our ability to retain and broaden adoption
with existing customers. Because our technology is novel, some customers
begin using our platform by initiating pilot studies involving a small
number of samples to gain experience with our service. As a result,
historically a significant portion of our revenues has come from existing
customers. We believe that our ability to convert initial pilots into
larger orders from existing customers has the potential to drive
substantial long-term revenue. We expect there may be some variation in
the number of samples they choose to test each quarter. • Adoption of our products and solutions by new customers. While new customers initially may not account for significant revenues, we believe that they have the potential to grow substantially over the long term as
they gain confidence in our service. Our ability to engage new customers
is critical to our long-term success. Our publications, posters and presentations at scientific conferences lead to engagement at the scientific level with potential customers who often make the initial decision to gain experience with our platform. Accessing these new customers through scientific engagement and marketing to gain initial buy-in is critical to our success and gives us the opportunity to demonstrate the utility of our platform.
• Our revenues and costs are affected by the volume of samples we receive
from customers from period to period. The timing and size of sample
shipments received after orders have been placed is variable. Since
sample shipments can be large, and are often received from a third party,
the timing of arrival can be difficult to predict over the short term.
Although our long-term performance is not affected, we do see
quarter-to-quarter volatility due to these factors. Samples arriving
later than expected may not be processed in the quarter proposed and
result in revenue the following quarter. Since many of our customers
request defined turnaround times, we employ project managers to coordinate and manage the complex process from sample receipt to sequencing and delivery of results.
• Investment in product innovation to support commercial growth. Investment
in research and development, including the development of new products is
critical to establish and maintain our leading position. In particular,
we have invested in NeoantigenID, a neoantigen characterization report,
ImmunogenomicsID, a broad biomarker report, and ImmunoID NeXT, our
universal cancer immunogenomics platform. We are also collaborating with
key opinion leaders from academic cancer centers, such asInova Health System , Stanford Medicine, and theParker Institute for Cancer Immunotherapy , to support the utility of our platform. We believe this
work is critical to gaining customer adoption and expect our investments
in these efforts to increase. We believe utility for our product may
result in additional expenditures to develop and market new products,
including a diagnostic or database.
• Leverage our operational infrastructure. We have invested significantly,
and will continue to invest, in our sample processing capabilities and commercial infrastructure. With our current operating model and infrastructure, we can increase our production and commercialize new
generations of our platform, but as our volumes continue to increase we
will ultimately need to invest in additional production capabilities. We
expect to grow our revenues and spread our costs over a larger volume of
services. In addition, we may invest significant amounts in infrastructure to support new products resulting from our research and development activities. In addition to the factors described above, as our headquarters and laboratory operations are located inSan Mateo County, California , our operations have been impacted by the ongoing COVID-19 pandemic. OnMarch 16, 2020 , the Health Officer of theCounty of San Mateo (the "Health Officer") issued a shelter-in-place order (the "San Mateo Order"), which directed all businesses to cease non-essential operations at physical locations in the county. TheSan Mateo Order also directed all individuals living in the county to shelter at their place of residence with limited exceptions. The intent of the San Mateo Order is to slow the spread of COVID-19 to the maximum extent possible. TheSan Mateo Order became effective onMarch 17, 2020 and will continue to be in effect throughApril 7, 2020 , or until it is extended, rescinded, superseded, or amended in writing by the Health Officer. Similar orders were issued in neighboring counties, includingSanta Clara County , such that the substantial majority of our employees are subject to a shelter-in-place order. While the SanMateo Order allows for continued operation of so-called Essential Businesses, which includes certain critical healthcare operations and services, to comply with the San Mateo Order, we are prioritizing the fulfillment of customer orders to those related to time-sensitive healthcare projects, such as in-process clinical trials, and will fulfill other customer orders to the extent we have the ability to do so with limited laboratory staffing. In addition, onMarch 19, 2020 , the Governor ofCalifornia and the State Public Health Officer and Director of theCalifornia Department of Public Health ordered all individuals living in theState of California to stay at their place of residence for an indefinite period of time (subject to certain exceptions to facilitate authorized necessary activities) to mitigate the impact of the COVID-19 pandemic (the "California Order" and, together with the San Mateo Order, the "Orders"). Other states inthe United States , includingMassachusetts andNew York , have followed suit by issuing orders with similar goals and restrictions. 60 -------------------------------------------------------------------------------- Beyond the immediate impact of the Orders to our operations, the ongoing COVID-19 pandemic, the Orders, and similar orders issued by other authorities to impose restrictions intended to mitigate the impact of the COVID-19 pandemic, may disrupt our supply chain, including our ability to acquire raw materials, disrupt customer demand, reduce our ability to receive customer samples on a normal basis, disrupt our customer and vendor relationships, divert management attention, and negatively impact employee productivity due to work-from-home policies. The scope and duration of such impact is highly uncertain. We are unable to predict or quantify the impact of any potential disruption to our supply chain, changes in consumer demand, or any other actions that may become necessary as events unfold.
Components of Operating Results
Revenues
We derive our revenues primarily from sequencing and data analysis services to support the development of next-generation cancer therapies and to support large scale genetic research programs. We support our customers by providing high-accuracy, validated genomic sequencing and advanced analytics. Many of these analytics are related to state-of-the-art biomarkers, including those relevant to immuno-oncology therapeutics such as checkpoint inhibitors. Our revenues are primarily generated through contracts with companies in the pharmaceutical industry, healthcare organizations, and government entities. Our ability to increase our revenues will depend on our ability to further penetrate this market. To do this, we are developing a growing set of additional state-of-the-art products, advancing our operational infrastructure, building our regulatory credentials and expanding our targeted marketing efforts. Unlike diagnostic or therapeutic companies, we have not to date sought reimbursement through traditional healthcare payors. We sell through a small direct sales force. We have one reportable segment from the sale of sequencing and data analysis services. Substantially all of our revenues to date have been derived from sales inthe United States . Costs and Expenses Costs of revenues Costs of revenues consist of production material costs, personnel costs (salaries, bonuses, benefits, and stock-based compensation), costs of consumables, laboratory supplies, depreciation and service maintenance on capitalized equipment, and information technology ("IT") and facility costs. We expect the costs of revenues to increase as our revenues grow, but the cost per unit of data delivered to decrease over time due to economies of scale we may gain as volume increases, automation initiatives, and other cost reductions.
Research and development expenses
Research and development expenses consist of costs incurred for the development of our products. These expenses consist primarily of payroll and personnel costs (salaries, bonuses, benefits, and stock-based compensation), costs of consumables, laboratory supplies, depreciation and service maintenance on capitalized equipment, and IT and facility costs. These expenses also include costs associated with our collaborations, which we expect to increase over time.
We expense our research and development expenses in the period in which they are incurred. We expect to increase our research and development expenses as we continue to develop new products.
Selling, general, and administrative expenses
Selling expenses consist of personnel costs, customer support expenses, direct marketing expenses, educational and promotional expenses, and market research. Our general and administrative expenses include costs for our executive, accounting, finance, legal, and human resources functions. These expenses consist of personnel costs, audit and legal expenses, consulting costs, and IT and facility costs. We expense all selling, general, and administrative expenses as incurred. We expect our selling expenses will continue to increase in absolute dollars, primarily driven by our efforts to expand our commercial capability and to expand our brand awareness and customer base through targeted marketing initiatives with an increased presence both within and outsidethe United States . We also expect general and administrative expenses will increase as we scale our operations. Interest Income 61
-------------------------------------------------------------------------------- Interest income consists primarily of interest earned on our cash and cash equivalents, and short-term investments. Interest income increased significantly in 2019 as a result of us investing proceeds from the IPO. We expect a continued higher level of interest income in 2020 for this reason.
Interest Expense
Interest expense primarily consists of cash and non-cash interest costs related to our term loan, convertible promissory notes, revolving loan, and growth capital loan. We record costs incurred in connection with the issuance of debt as a direct deduction from the debt liability. We amortize these costs over the term of our debt agreements as interest expense in our consolidated statements of operations. After the payoff of our growth capital loan inAugust 2019 , we no longer have any outstanding debt and have not incurred interest expense from that point forward. Loss on Debt Extinguishment We incurred loss on debt extinguishment in 2018 resulting from changes in the maturity dates of the convertible notes issued in 2017. We also incurred loss on debt extinguishment in 2019 upon the payoff of the growth capital loan. See Note 6 to our consolidated financial statements included elsewhere in this annual report. Other (Expense) Income, Net Other (expense) income, net consists of changes in the fair value of the compound derivative instrument, changes in fair value of convertible preferred stock warrant liability, and foreign currency exchange gains and losses. Future periods will not include changes in fair value of the compound derivative instrument, due to extinguishment of the related convertible notes, nor will future periods include changes in fair value of convertible preferred stock warrants, due to the conversion of such warrants to common stock warrants. See Notes 6 and 10 included elsewhere in this annual report for further discussion of these two items. We expect our foreign currency gains and losses to continue to fluctuate in the future due to changes in foreign currency exchange rates.

The cost components related to the increase in costs of revenues were an$11.7 million increase in production materials, a$2.2 million increase related to personnel costs including salaries, bonuses, benefits, and stock-based compensation expenses, a$1.6 million increase in depreciation and service maintenance on capitalized equipment, a$0.5 million increase in the consumption cost of consumables and laboratory supplies, a$0.9 million increase in IT and facility costs, and a$0.3 million increase in other costs.
Research and development
The increase in 2019 was primarily due to increased development activities for new product offerings, lab and automation development costs, and IT and facility costs. Research and development expenses increased due to an increase of$4.0 million in personnel-related expenses, including salaries, bonuses, benefits, and stock-based compensation expenses, a$2.8 million increase in laboratory and automation supplies consumed, a$1.2 million increase in depreciation, service maintenance on capitalized equipment, and cost of expensed equipment, and$0.2 million increase in other costs.
Selling, general and administrative
The increase in 2019 was due to a$7.3 million increase in personnel-related expenses including salaries, bonuses, benefits, and stock-based compensation expenses primarily related to increased headcount, a$3.0 million increase in professional services primarily related to public company-related costs (including corporate insurance, audit fees, and legal expenses), and a$0.5 million increase in other costs. 63

-------------------------------------------------------------------------------- From our inception throughDecember 31, 2019 , we have funded our operations primarily from$144.0 million in net proceeds from our initial public offering inJune 2019 and$89.6 million from issuance of redeemable convertible preferred stock, as well as cash from operations and debt financing. OnMarch 22, 2019 , we received$20.0 million in gross cash proceeds from a growth capital loan. As ofDecember 31, 2019 , we had cash and cash equivalents in the amount of$55.0 million . We have incurred net losses since our inception. We anticipate that our current cash and cash equivalents and marketable securities, together with cash provided by operating activities are sufficient to fund our near-term capital and operating needs for at least the next 12 months. We have based these future funding requirements on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. If our available cash balances, net proceeds from the offering and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements including because of lower demand for our services or other risks described in this annual report, we may seek to sell additional common or preferred equity or convertible debt securities, enter into an additional credit facility or another form of third-party funding or seek other debt financing. The sale of equity and convertible debt securities may result in dilution to our stockholders and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. The terms of debt securities issued or borrowings pursuant to a credit agreement could impose significant restrictions on our operations. Additional capital may not be available on reasonable terms, or at all. OnMarch 22, 2019 , we entered into a growth capital loan (the "Growth Capital Loan") with TriplePoint to provide for a$20.0 million growth capital loan facility and as ofJune 30, 2019 , had drawn down the full$20.0 million available under the facility. We used$5.1 million of the Growth Capital Loan to repay, in its entirety, all amounts outstanding under the Revolving Loan. Borrowings under the Growth Capital Loan bore interest at a floating rate of prime, plus 5.00%, for borrowings up to$15.0 million and the prime rate plus 6.50% for borrowings greater than$15.0 million . Under the agreement, we were required to make monthly interest-only payments throughApril 1, 2020 and required to make 36 equal monthly payments of principal, plus accrued interest, fromApril 1, 2020 throughMarch 1, 2023 , when all unpaid principal and interest was to become due and payable. The agreement allowed voluntary prepayment of all, but not part, of the outstanding principal at any time prior to the maturity date, subject to a prepayment fee of 1.00% of the outstanding balance if prepaid in months one through 12 of the loan term. In addition to the final payment, we paid an amount equal to 2.75% of each principal amount drawn under this growth capital loan facility. In connection with the Growth Capital Loan, we issued a warrant to purchase 65,502 shares of common stock to TriplePoint at an exercise price of$9.16 per share exercisable for seven years fromMarch 22, 2019 . We recorded the issuance-date fair value of the warrant of$0.6 million and fees paid to TriplePoint of$0.3 million as a debt discount, which was amortized over the term of the Growth Capital Loan using the effective interest method. Upon issuance, the Growth Capital Loan had an effective interest rate of 15.23% per year. Interest expense for the year endedDecember 31, 2019 was$1.0 million .
On
Our short-term investments portfolio is primarily invested in highly rated securities, with the primary objective of minimizing the potential risk of principal loss. Our investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer.
During 2019, cash used by operating activities of$18.1 million was a result of$25.1 million of net loss and the net negative change in operating assets and liabilities of$7.3 million , partially offset by non-cash negative adjustments to net income of$14.3 million .
Cash used by investing activities of
Cash provided by financing activities of$134.9 million during 2019 consisted primarily of$139.8 million of proceeds from initial public offering, net of underwriting discounts and commissions,$1.4 million of proceeds from issuance of common stock under employee stock plans, and net proceeds from the issuance of a Growth Capital Loan of$20.0 million , partially offset by cash used to repay a revolving loan and issue and repay the Growth Capital Loan of$26.3 million . 65

Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance withU.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and related disclosures. Our estimates are based on our historical experience and on various other factors that 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 that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if changes in the estimate that are reasonably possible could materially impact the financial statements. We believe that the assumptions and estimates associated with the accounting policies discussed below have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.
Revenue Recognition
Adoption of ASC Topic 606, "Revenue from Contracts with Customers"
OnJanuary 1, 2017 , we early adopted the new accounting standard ASC Topic 606 using the full retrospective method. Results for reporting periods beginning afterJanuary 1, 2017 , are presented under ASC Topic 606. The impact of adopting ASC Topic 606 was not material on our consolidated financial statements.
Revenue Recognition
We generate our revenues from selling sequencing and data analysis services. We agree to provide services to our customers through a contract, which may be in the form of a combination of a signed agreement, statement of work and/or a purchase order. Upon adoption of ASC Topic 606, we have evaluated the performance obligations contained in contracts with customers to determine whether any of the performance obligations are distinct, such that the customers can benefit from the obligations on their own, and whether the obligations can be separately identifiable from other obligations in the contract. For all of our contracts to date, the customer orders a specified quantity of a sequencing; therefore, the delivery of the ordered quantity per the purchase order is accounted for as one performance obligation. Our contracts include only one performance obligation-the delivery of the sequencing and data analysis services to the customer. Fees for our sequencing and data analysis services are predominantly based on a fixed price per sample. The fixed prices identified in the arrangements only change if a pricing amendment is agreed with a customer. In limited cases we provide our customers a discount if samples received are above a certain volume are purchased. In such cases, the discount applies prospectively. We have analyzed such discounts if they represent a material right provided to a customer. We have concluded that such discounts do not represent a material right provided to a customer since they are not deemed to be incremental to the pricing offered to the customer, or are not enforceable options to acquire additional goods. As a result, these discounts do not constitute a material right and do not meet the definition of a separate performance obligation. We do not offer retrospective discounts or rebates. Accordingly, all of 66 -------------------------------------------------------------------------------- the transaction price, net of any discounts, is allocated to one performance obligation. Therefore, upon delivery of the services, there are no remaining performance obligations. Contracts that contain multiple distinct performance obligations would require an allocation of the transaction price to each performance obligation based on a relative stand-alone selling price basis. Sometimes we deliver sequencing results in two or more batches; however, since the quantity delivered per batch of each individual test per sales order in these instances is in the same ratio as in the original sales order, allocating the transaction price on a relative stand-alone selling price basis would have no impact on the revenue recognized in any period presented. We recognize revenue when control of the promised services is transferred to our customers. Management applies judgment in evaluating when a customer obtains control of the promised service, which is when the sequencing and data analysis service results are delivered to customers, at an amount that reflects the consideration to which we expect to be entitled to in exchange for those services. Revenue is recorded net of sales or other transaction taxes collected from clients and remitted to taxing authorities. A customer contract liability will arise when we have received payments from its customers in advance, but has not yet provided genome and exome sequencing and data analysis services to a customer and satisfied its performance obligations. We record a customer contract liability for performance obligations outstanding related to payments received in advance for customer deposits. We expect to satisfy these remaining performance obligations and recognize the related revenues upon providing sequencing and data analysis services.
All of our revenues and trade receivables are generated from contracts with
customers and substantially all of our revenues are derived from
Payment Terms
Payment terms and conditions vary by contract and customer. Our standard payment terms are typically less than 90 days from the date of invoice. In instances where the timing of our revenue recognition differs from the timing of its invoicing, we have determined that our contracts do not include a significant financing component. The primary purposes of our invoicing terms are to provide customers with simplified and predictable ways of purchasing our services and provide payment protection for us.
Convertible Preferred Stock Warrants
We accounted for warrants to purchase shares of our redeemable convertible preferred stock as liabilities at their estimated fair value because the warrants may have obligated us to transfer assets to the holders at a future date upon a deemed liquidation event. The warrants were recorded at fair value upon issuance and were subject to remeasurement to fair value at each period end, with any fair value adjustments recognized in the consolidated statements of operations and comprehensive loss. We adjusted the warrant liability for changes in fair value until the conversion of redeemable convertible preferred stock into common stock.
Common Stock Warrants
Our common stock warrants are classified as equity as they meet all criteria for equity classification. The common stock warrants were recorded at fair value upon issuance, or conversion to common stock warrants in the case of our convertible preferred stock warrants, as additional paid-in-capital in the consolidated balance sheets. The common stock warrants are not subsequently remeasured.
Convertible Instruments
We evaluate and account for conversion options embedded in convertible instruments in accordance with ASC Topic 815, Derivatives and Hedging Activities. Applicable GAAP requires companies to bifurcate conversion options from their host instruments and account for them as freestanding derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not remeasured at fair value under other GAAP with changes in fair value reported in earnings as they occur, and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument.
Stock-Based Compensation
We account for stock-based compensation arrangements with employees, using a fair value-based method, for costs related to all stock-based payments including stock options and stock awards. Our determination of the fair value of stock options on the date of grant utilizes the Black-Scholes option-pricing model. 67 -------------------------------------------------------------------------------- The fair value of the option granted is recognized over the period during which an optionee is required to provide services in exchange for the option award, known as the requisite service period which usually is the vesting period, on a straight-line basis. Estimating the fair value of equity-settled awards as of the grant date using valuation models, such as the Black-Scholes option-pricing model, is affected by assumptions regarding a number of complex variables. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. These inputs are subjective and generally require significant analysis and judgment to develop.
• Expected Term-The expected term assumption represents the
weighted-average period that the stock-based awards are expected to be outstanding. We have elected to use the "simplified method" for estimating the expected term of the options, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option.
• Expected Volatility-For all stock options granted to date, the volatility
data was estimated based on a study of publicly traded industry peer companies. For purposes of identifying these peer companies, we considered the industry, stage of development, size, and financial leverage of potential comparable companies.
• Expected Dividend Yield-The Black-Scholes option-pricing valuation model
calls for a single expected dividend yield as an input. We currently have
no history or expectation of paying cash dividends on our common stock. • Risk-Free Interest Rate-The risk-free interest rate is based on the yield
available onU.S. Treasury zero-coupon issues similar in duration to the expected term of the equity-settled award. We estimated the fair value of the time-based employee stock options using the Black-Scholes option-pricing model based on the date of grant with the following assumptions: Common Stock Valuations The estimated fair value of the common stock underlying our stock options was determined at each grant date by our board of directors, with input from management. All options to purchase shares of our common stock are intended to be exercisable at a price per share not less than the per-share fair value of our common stock underlying those options on the date of grant. In the absence of a public trading market for our common stock prior to our IPO, on each grant date, we developed an estimate of the fair value of our common stock based on the information known to us on the date of grant, upon a review of any recent events and their potential impact on the estimated fair value per share of the common stock, and in part on input from an independent third-party valuation firm. As provided in Section 409A of theU.S. Internal Revenue Code of 1986, as amended (the "Code"), we generally relied on our valuations for up to 12 months unless we experienced a material event that would have affected the estimated fair value per common share. Our valuations of our common stock were determined in accordance with the guidelines outlined in theAmerican Institute of Certified Public Accountants Practice Aid , Valuation of Privately-Held-Company Equity Securities Issued as Compensation (the "Practice Aid"). The methodology to determine the fair value of our common stock included estimating the fair value of the enterprise using the "backsolve" method, which estimates the fair value of our company by reference to the value and preferences of our last round of financing, as well as our capitalization.
The assumptions used to determine the estimated fair value of our common stock were based on numerous objective and subjective factors, combined with management's judgment, including external market conditions affecting the pharmaceutical and biotechnology industry and trends within the industry:
• our stage of development;
• the rights, preferences, and privileges of our redeemable convertible
preferred stock relative to those of our common stock; • the prices at which we sold shares of our redeemable convertible preferred stock;
• our financial condition and operating results, including our levels of
available capital resources; • the progress of our research and development efforts, our stage of development, and business strategy; • equity market conditions affecting comparable public companies; and • general U.S. market conditions and the lack of marketability of our common stock. 68
-------------------------------------------------------------------------------- The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date. In accordance with the Practice Aid, we considered the following methods:
• Income approach. The income approach attempts to value an asset or
security by estimating the present value of the future economic benefits
it is expected to produce. These benefits can include earnings, cost savings, tax deductions, and disposition proceeds from the asset. An
indication of value may be developed in this approach by discounting
expected cash flows to their present value at a rate of return that incorporates the risk-free rate for the use of funds, the expected rate
of inflation over the asset's holding period, and the risks associated
with realizing the cash flows in the amounts and at the times projected.
The discount rate selected is typically based on rates of return available from alternative investments of similar type and quality as of the valuation date. The most commonly employed income approach to valuation is the discounted cash flow analysis. • Market Approach. The market approach attempts to value an asset or security by examining observable market values for similar assets or
securities. Sales and offering prices for comparable assets are adjusted
to reflect differences between the asset being valued and the comparable
assets, such as, location, time and terms of sale, utility, and physical
characteristics. When applied to the valuation of equity, the analysis
may include consideration of the financial condition and operating
performance of the company being valued relative to those of publicly
traded companies or to those of companies acquired in a single
transaction, which operate in the same or similar lines of business. • Cost Approach. The cost approach to valuation is based upon the concept of replacement cost as an indicator of value and the notion that an investor would pay no more for an asset than what it would cost to
replace the asset with one of equal utility. The cost approach estimates
value based upon the estimated cost of replacing or reproducing the asset, less adjustments for physical deterioration and functional obsolescence, if relevant. When applied to an enterprise, a type of cost
approach referred to as the Net Asset Method is sometimes employed. This
method measures the value of equity as the sum of the values of its
assets reduced by the sum of the values of its liabilities. The resulting
equity is reflective of a 100% ownership interest in the business. This approach is frequently used in valuing holding companies. Based on our early stage of development and other relevant factors, we considered all three approaches and chose to apply both income and market approaches in our analyses. We determined these approaches were the most appropriate methods for allocating our enterprise value to determine the estimated fair value of our common stock for valuations performed for periods up to our IPO. In determining the estimated fair value of our common stock, our board of directors also considered the fact that our stockholders could not freely trade our common stock in the public markets. Accordingly, we applied discounts to reflect the lack of marketability of our common stock based on the weighted-average expected time to liquidity. The estimated fair value of our common stock at each grant date reflected a non-marketability discount partially based on the anticipated likelihood and timing of a future liquidity event.
Following our IPO, our board of directors determines the fair value of our common stock based on the closing quoted market price of our common stock on the date of grant.
Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are determined based on differences between the financial statement reporting and tax bases of assets and liabilities and net operating loss and credit carryforwards and are measured using the enacted tax rates and laws that will be in effect when such items are expected to reverse. Deferred income tax assets are reduced, as necessary, by a valuation allowance when management determines it is more likely than not that some or all of the tax benefits will not be realized. We assess all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by relevant taxing authorities. Assessing an uncertain tax position begins with the initial determination of the position's sustainability and is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. We have elected to account for the tax on Global Intangible Low-Taxed Income, enacted as part of the Tax Cuts and Jobs Act as a component of tax expense in the period in which the tax is incurred.
JOBS Act Accounting Election
We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act (the "JOBS Act"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. 69
