Overview

We are a clinical-stage biopharmaceutical company currently focused on developing differentiated therapies for patients with gastrointestinal, or GI, diseases. Our most advanced program, MET642, targets the farnesoid X receptor, or FXR, which is central to modulating GI and liver diseases.

Prior to February 2022, we were developing another FXR agonist, MET409, for the treatment of non-alcoholic steatohepatitis, or NASH, a liver disease characterized by excess liver fat, inflammation and fibrosis. While we believe these two compounds demonstrate potential for differentiated treatments in both monotherapy and combination treatment for NASH, given recent clinical outcomes of our programs relative to competing programs, reduced investor sentiment in NASH, and the significant resources required to pursue further development in NASH, we elected to discontinue future development of our FXR program in NASH while prioritizing our resources and efforts toward the development of MET642 for the treatment of Ulcerative Colitis, or UC, one of the two primary types of Inflammatory Bowel Disease, or IBD. We were also developing small molecule inhibitors of HSD17?13 for the treatment of NASH. HSD17?13 is a genetically validated target for advanced liver disease. In February 2022, our board of directors approved a corporate restructuring plan, or Restructuring Plan, that resulted in the reduction of approximately 50% of our workforce, primarily consisting of our research organization, which consequently resulted in the discontinued development of our hydroxysteroid dehydrogenase, or HSD, program. The Restructuring Plan was completed in April 2022.

We have engaged MTS Health Partners to act as our strategic financial advisor. We are evaluating and exploring a variety of strategic and financing alternatives focused on maximizing shareholder value, including, but not limited to, a merger, sale, or other business combination, a strategic partnership with one or more parties, or the licensing, sale or divestiture of our programs. Despite undertaking this process, we may not be successful in completing a transaction, and, even if a strategic transaction is completed, it ultimately may not deliver the anticipated benefits or enhance stockholder value.

We believe FXR plays a key role in the treatment of IBD, including UC. FXR is highly expressed by intestinal epithelial cells and plays a key role in healthy intestinal function by maintaining the epithelial barrier, reducing bacterial translocation into the intestinal wall and regulating the innate immune response. FXR-based therapies in IBD address multiple aspects of IBD pathogenesis without the immunosuppression inherent to other advanced-line therapies.

IBD is a significant global health issue and is thought to occur due to a maladaptive immune response to gut microbes. UC and Crohn's disease are the two primary types of IBD. Patients with IBD can suffer from abdominal pain and bloody diarrhea and also be at increased risk of colorectal cancer. The global incidence of IBD is increasing and as of 2015, it was estimated that there were 3.1 million people in the United States with IBD. Our first clinical investigation of FXR therapy in IBD will be focused on patients with UC.

We believe an oral, once-daily therapy with FXR agonists could be an attractive treatment option for UC patients that may prefer oral administration instead of injectable biologics that are cumbersome to administer chronically. In preclinical animal studies with our current and previous FXR agonist product candidates, we have observed statistically significant improvements in colon histology and at levels similar to that of a mouse antibody which targets IL-12/23. The IL-12/23 pathway is the target of current approved biologic therapies.

We have delayed clinical development efforts related to our planned Phase 2a proof-of-concept clinical trial of MET642 in UC until the completion of our review of strategic alternatives. The planned UC trial is currently designed as a 12-week randomized, double blind, placebo controlled, multi-center clinical trial evaluating the efficacy and safety of two dose levels of MET642, compared to placebo, over 12 weeks of treatment. Eligible patients will be randomized in a 1:1:1 ratio to receive MET642 (3 mg), MET642 (6 mg) or placebo. Each trial drug will be given once daily by oral administration. The trial is designed to enroll up to 165 patients in the United States and in Europe. An interim analysis is planned once 50% of the patients have completed treatment in the trial.

There may be changes to the design of the planned UC trial depending upon the outcome of our review and as part of the strategic alternatives being considered. These changes could result in further delays, significant increases to the cost of the planned UC trial, or the discontinuation of the planned UC trial.

To date, we have devoted substantially all of our resources to organizing and staffing our company, business, planning, raising capital, researching, discovering and developing our pipeline in FXR and other drug targets and general and administrative support for these operations. We do not have any products approved for sale and have not generated any product sales. We have funded our



                                       15

--------------------------------------------------------------------------------

operations primarily through the private placement of convertible preferred stock, the issuance of long-term debt, and the sale of common stock from our initial public offering, or IPO, and our at-the-market equity offering program, or ATM offering program. Through March 31, 2022, we have raised gross proceeds of approximately $124.8 million from the issuance of convertible preferred stock, $15.0 million under our K2 Loan Agreement (as defined below) and $107.7 million from the sale of common stock from our IPO and our ATM offering program. As of March 31, 2022 and December 31, 2021, we had cash, cash equivalents, and short-term investments of $62.7 million and $76.4 million, respectively.

We have incurred net losses since our inception. Our net losses were $12.9 million and $14.8 million for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, we had an accumulated deficit of $195.8 million. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and preclinical studies and our expenditures on other research and development activities. We expect our expenses and operating losses will increase as MET642 or any future product candidates advance through clinical trials, and as we expand our clinical, regulatory, quality and manufacturing capabilities, incur significant commercialization expenses for marketing, sales, manufacturing and distribution, if we obtain marketing approval for MET642 or any future product candidate, and incur additional costs associated with operating as a public company.

We do not expect to generate any revenues from product sales unless and until we successfully complete development and obtain regulatory approval for one or more product candidates, which will not be for many years, if ever. Accordingly, until such time as we can generate significant revenue from sales of MET642 or any future product candidate, if ever, we expect to finance our operations through a combination of equity offerings, debt financings, additional borrowings under the K2 Loan Agreement, strategic transactions, collaborations, and other similar arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements when needed would have a negative impact on our financial condition and could force us to delay, reduce or terminate our development programs or other operations, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Financial Operations Overview

Revenues

To date, we have not generated any revenues from the commercial sale of any products, and we do not expect to generate revenues from the commercial sale of any products for the foreseeable future, if ever.

Research and Development Expenses

To date, our research and development expenses have related primarily to discovery efforts and preclinical and clinical development of our product candidates. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received.

Research and development expenses include:


   •  salaries, payroll taxes, employee benefits and stock-based compensation
      charges for those individuals involved in research and development efforts;


   •  external research and development expenses incurred under agreements with
      contract research organizations, or CROs, investigative sites and
      consultants to conduct our preclinical, toxicology and clinical studies;


   •  costs related to manufacturing our product candidates for clinical trials
      and preclinical studies, including fees paid to third-party manufacturers;


  • laboratory supplies;


  • costs related to compliance with regulatory requirements; and


   •  facilities, depreciation and other allocated expenses, which include direct
      and allocated expenses for rent, maintenance of facilities, insurance,
      equipment and other supplies.

The following table summarizes our research and development expenses allocated by program for the three months ended March 31, 2022 and 2021 (in thousands):

                                      1,749         2,898
Total research and development expenses               $   6,680      $ 10,857

Unallocated expenses consist primarily of our internal personnel related costs, facility costs, and lab supplies.



                                       16

--------------------------------------------------------------------------------

Our Restructuring Plan, which we implemented in February 2022 and completed in April 2022, resulted in the reduction of approximately 50% of our workforce, primarily consisting of our research organization, and as a result, we will not incur research expenses for the foreseeable future. We expect our development expenses will fluctuate in the future as we review the development plan and timeline of our FXR program in IBD and as we evaluate strategic alternatives. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future clinical trials of MET642 or any future product candidate due to the inherently unpredictable nature of preclinical and clinical development. Clinical and preclinical development timelines, the probability of success and development costs can differ materially from expectations. We will need to raise substantial additional capital in the future. In addition, we cannot forecast whether MET642 or any future product candidate may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

Our development costs may vary significantly based on factors such as:


  • per patient trial costs;


  • the number and scope of preclinical studies;


  • the number of trials required for approval;


  • the number of sites included in the trials;


  • the countries in which the trials are conducted;


  • the length of time required to enroll eligible patients;


  • the number of patients that participate in the trials;


  • the number of doses that patients receive;


  • the drop-out or discontinuation rates of patients;


  • potential additional safety monitoring requested by regulatory agencies;


  • the duration of patient participation in the trials and follow-up;


  • the phase of development of the product candidate;


  • the efficacy and safety profile of the product candidate; and


   •  the extent to which we collaborate with biopharmaceutical companies for the
      development and potential commercialization of the product candidate.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation, for personnel in executive, finance, and other administrative functions. Other significant costs include facility-related costs, legal fees relating to intellectual property and corporate matters, professional fees for accounting and consulting services, and insurance. We anticipate that our general and administrative expenses will increase in the future to support our development and other commercial activities if MET642 or any future product candidate receives marketing approval.

Restructuring Charges

Restructuring charges consist primarily of (i) one-time payments relating to severance obligations and other customary employee benefits and the acceleration of the vesting of certain equity awards in connection with the staff reduction and (ii) third-party costs associated with the discontinuation of our HSD program. Refer to Note 9 in our unaudited condensed consolidated financial statements for further discussion.

Gain from Lease Termination and Asset Sale

Gain from lease termination and asset sale relates to the termination of the facility lease for our former corporate headquarters and the sale of personal property to Belharra Therapeutics, Inc., or Belharra. Refer to Note 3 in our unaudited condensed consolidated financial statements for further discussion.

Total Other Income (Expense)

Total other income (expense) consists primarily of interest income from our cash, cash equivalents, and short-term investments and interest expense under our K2 Loan Agreement.

Research and Development Expenses. Research and development expenses were $6.7 million and $10.9 million for the three months ended March 31, 2022 and 2021, respectively. The decrease in research and development expenses of $4.2 million when comparing the three months ended March 31, 2022 and 2021 was primarily due to decreases of $2.0 million in clinical trial expenses related to our FXR program, $0.9 million in preclinical studies and toxicology expenses, $0.8 million in personnel costs, including $0.4 million in non-cash stock-based compensation, $0.1 million in laboratory supplies expense, and $0.1 million of lower facilities and information technology expenses.

General and Administrative Expenses. General and administrative expenses were $5.5 million and $3.7 million for the three months ended March 31, 2022 and 2021, respectively. The increase in general and administrative expenses of $1.8 million when comparing the three months ended March 31, 2022 and 2021 was primarily due to increases of $1.4 million in personnel costs, including $0.9 million in non-cash stock-based compensation, $0.2 million in consulting, professional services, and other public company related expenses, and $0.1 million in higher facilities and information technology expenses.

Restructuring Charges. Restructuring charges were $0.9 million and none for the three months ended March 31, 2022 and 2021, respectively. The increase in restructuring charges of $0.9 million when comparing the three months ended March 31, 2022 and 2021 was primarily related to one-time payments of severance obligations and other customary employee benefits made in connection with the staff reduction resulting from the Restructuring Plan. Refer to Note 9 in our unaudited condensed consolidated financial statements for further discussion.

Gain from Lease Termination and Asset Sale. Gain from lease termination and asset sale was $0.5 million and none for the three months ended March 31, 2022 and 2021, respectively. The gain from lease termination and asset sale of $0.5 million during the three months ended March 31, 2022 was related to the termination of the facility lease for our former corporate headquarters and sale of personal property to Belharra. There was no such activity during the three months ended March 31, 2021. Refer to Note 3 in our unaudited condensed consolidated financial statements for further discussion.

Liquidity and Capital Resources

We have incurred net losses and negative cash flows from operations since our inception and anticipate we will continue to incur net losses for the foreseeable future. As of March 31, 2022 and December 31, 2021, we had cash, cash equivalents, and short-term investments of $62.7 million and $76.4 million respectively.

Cash Flows

The following table sets forth a summary of the net cash flow activity for each of the periods indicated (in thousands):

--------------------------------------------------------------------------------

Operating Activities

Net cash used in operating activities was $13.7 million and $12.2 million for the three months ended March 31, 2022 and 2021, respectively. The net cash used in operating activities during the three months ended March 31, 2022 was primarily due to our net loss of $12.9 million and $2.7 million from changes in operating assets and liabilities, adjusted for $1.9 million of non-cash charges. Non-cash charges for the three months ended March 31, 2022 primarily consisted of $2.0 million of stock-based compensation and $0.4 million in other non-cash charges, partially offset by a $0.5 million gain from lease termination and asset sale related to the termination of the facility lease for our former corporate headquarters.

Net cash used in operating activities was $12.2 million for the three months ended March 31, 2021 and was primarily due to our net loss of $14.8 million, adjusted for $2.0 million of non-cash charges and $0.6 million from changes in operating assets and liabilities. Non-cash charges for the three months ended March 31, 2021 primarily consisted of $1.5 million of stock-based compensation, $0.2 million of amortization on our right-of-use asset and $0.3 million in other non-cash charges.

Investing Activities

Net cash used in investing activities of $2.2 million for the three months ended March 31, 2022 was due primarily to purchases of short-term investments of $12.7 million, partially offset by sales and maturities of short-term investments of $10.5 million.

Net cash provided by investing activities of $6.6 million for the three months ended March 31, 2021 was due primarily to sales and maturities of short-term investments of $19.4 million, partially offset by purchases of short-term investments of $12.8 million.

Financing Activities

There was no cash provided by financing activities for the three months ended March 31, 2022.

Net cash provided by financing activities of $0.6 million for the three months ended March 31, 2021 was due primarily to proceeds from exercises of common stock options.

Loan Agreement

In August 2019, we borrowed $10.0 million in the first tranche under a loan and security agreement, or the K2 Loan Agreement, with K2 HealthVentures Equity Trust LLC, or K2, which was subsequently amended in March 2020 and October 2021. In October 2021, we amended the K2 Loan Agreement and thereby replaced and superseded the $10.0 million of existing term loan tranches with new term loan tranches that enable us to borrow up to an aggregate of $45.0 million upon the achievement of certain milestones. We have borrowed $15.0 million under the first tranche, or the 2021 Refinancing Term Loans, and currently have $20.0 million in term loan tranches available to us upon the achievement of certain milestones under the terms of the K2 Loan Agreement.

Term loans under the K2 Loan Agreement bear interest at a floating annual rate equal to the greater of (i) the prime rate used by lender plus 4.5% and (ii) 7.75%. The monthly payments on the 2021 Refinancing Term Loans are interest-only until July 1, 2023, and then subsequent to the interest-only period, the 2021 Refinancing Term Loans will be payable in equal monthly installments of principal plus accrued and unpaid interest, through April 1, 2025, the maturity date. We are required to make final fee payments equal to $0.5 million on September 1, 2023 and 5.75% of the aggregate original principal amount of the 2021 Refinancing Term Loans at the maturity date. We may elect to prepay all, but not less than all, of the 2021 Refinancing Term Loans prior to the maturity date, subject to a prepayment fee of up to 3.0% of the then outstanding principal balance. After repayment, no term loan amounts may be borrowed again.

Our obligations under the K2 Loan Agreement are secured by a security interest in substantially all of our assets, other than our intellectual property. The K2 Loan Agreement includes customary affirmative and negative covenants and also includes standard events of default, including an event of default based on the occurrence of a material adverse event, and a default under any agreement with a third party resulting in a right of such third party to accelerate the maturity of any debt in excess of $0.3 million. The negative covenants include, among others, restrictions on us transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying cash dividends or making other distributions, making investments, creating liens, selling assets and making any payment on subordinated debt, in each case subject to certain exceptions. Upon the occurrence and continuance of an event of default, the lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the K2 Loan Agreement. As of March 31, 2022, we were in compliance with all applicable covenants under the K2 Loan Agreement.

Sales Agreement

On October 4, 2021, we entered into a sales agreement, or the Sales Agreement, with SVB Leerink LLC, or SVB Leerink, to sell shares of common stock from time to time through our ATM offering program, under which SVB Leerink will act as our sales agent. We have no obligation to sell any shares of common stock under the Sales Agreement and may at any time suspend solicitation and offers under the Sales Agreement. SVB Leerink will be entitled to compensation in an amount of up to 3.0% of the gross proceeds of any shares of common stock sold under the Sales Agreement. A maximum of $50.0 million of shares of common stock may be sold under the Sales Agreement. We did not sell any shares of our common stock under the Sales Agreement during the three months



                                       19

--------------------------------------------------------------------------------

ended March 31, 2022. As of March 31, 2022, we may sell up to an additional $27.3 million of shares of our common stock under the Sales Agreement and pursuant to our ATM offering program.

Material Cash Requirements

Our material cash requirements from known contractual obligations have not changed materially since our Annual Report.

On March 11, 2022, we entered into an Agreement for Termination of Lease and Voluntary Surrender of Premises, or Lease Termination Agreement, with ARE-SD Region No. 30, LLC, or Landlord, to accelerate the termination of the operating lease for our former corporate headquarters, or our Corporate Lease. Under the terms of the Lease Termination Agreement, our Corporate Lease would terminate on the later of March 31, 2022 and the date that Landlord notifies us that it has executed a lease agreement with a third party for the premises. On March 31, 2022, or the Lease Termination Date, Landlord notified us that our Corporate Lease had been terminated pursuant to the terms of the Lease Termination Agreement. Since the Lease Termination Date, we have had no further obligations under our Corporate Lease and have transitioned to a fully remote work environment and no longer maintain a corporate headquarters. We believe that a fully remote work environment will be adequate to meet our needs for the immediate future, and that we will be able to obtain access to suitable physical office space in the future to the extent necessary.

We believe that our existing cash, cash equivalents and short-term investments will be sufficient to meet our material cash requirements through at least the next twelve months based on our current operating plans. We expect to finance our long-term cash requirements and obligations through a combination of existing cash and cash equivalents and equity offerings and debt financings, as well as business combinations, collaborations and other similar strategic alternatives. Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. We have based this estimate on assumptions that may prove to be wrong or change, and we could expend our capital resources sooner than we expect.

Our future cash requirements will depend on many factors, including:


   •  the scope, rate of progress and costs of our drug discovery, preclinical
      development activities, laboratory testing and clinical trials for MET642 or
      any future product candidate;


  • the number and scope of clinical programs we decide to pursue;


   •  the extent to which we collaborate with biopharmaceutical companies for the
      development and potential commercialization of MET642 or any future product
      candidates;


   •  the scope and costs of manufacturing for MET642 or any future product
      candidate and commercial manufacturing activities;


   •  the cost, timing and outcome of regulatory review of MET642 or any future
      product candidate;


   •  the costs of preparing, filing and prosecuting patent applications,
      maintaining and enforcing our intellectual property rights and defending
      intellectual property-related claims;


   •  the terms and timing of establishing and maintaining collaborations,
      licenses and other similar arrangements;


  • the terms and timing of any strategic transaction we may enter into;


   •  our efforts to enhance operational systems and our ability to attract, hire
      and retain qualified personnel, including personnel to support the
      development of MET642 or any future product candidate;


  • the costs associated with being a public company;


   •  the timing of any milestone and royalty payments to The Salk, or other
      future licensors;


   •  the extent to which we acquire or in-license other product candidates and
      technologies; and


   •  the cost associated with commercializing MET642 or any future product
      candidate, if they receive marketing approval.

Until such time, if ever, as we can generate substantial product revenues to support our cost structure, we expect to finance our operations through a combination of equity offerings, debt financings, strategic transactions, collaborations, and other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our common stock. If we are unable to raise additional sufficient capital when needed, we may be required to:


  • delay, reduce or eliminate our development programs or other operations;


   •  enter into strategic transactions or grant rights to develop and market
      product candidates that we would otherwise prefer to develop and market
      ourselves, or on terms that are less favorable than might otherwise be
      available;


   •  dispose of technology assets, or relinquish or license on unfavorable terms,
      our rights to technologies or any future product candidates that we
      otherwise would seek to develop or commercialize ourselves;


   •  pursue the sale of our company to a third party at a price that may result
      in a loss on investment for our stockholders; or


  • file for bankruptcy or cease operations altogether.

Any of these events could have a material adverse effect on our business, operating results and prospects.

Critical Accounting Estimates

Our management's discussion and analysis of our financial condition and results of operations are based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in our unaudited condensed consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and stock-based compensation. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 1 to our unaudited condensed consolidated financial statements appearing elsewhere in this Quarterly Report, we believe the following accounting policies and estimates to be most critical to the preparation of our unaudited condensed consolidated financial statements.

Accrued Expenses

We make estimates of our accrued research and development expenses for services performed by our vendors in connection with research and development activities for which we have not yet been invoiced. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost.

We make estimates of our accrued expenses as of each balance sheet date based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses include the costs incurred for services performed by our vendors in connection with research and development activities for which we have not yet been invoiced.

We base our expenses related to research and development activities on our estimates of the services received and efforts expended pursuant to quotes and contracts with vendors that conduct research and development on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made.

Although we do not expect our estimates to be materially different from amounts actually incurred, if our estimates of the status and timing of services performed differ from the actual status and timing of services performed, it could result in us reporting amounts that are too high or too low in any particular period. To date, there have been no material differences between our estimates of such expenses and the amounts actually incurred.

Stock-Based Compensation Expense

Stock-based compensation expense represents the cost of the grant date fair value of equity awards recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. We estimate the fair value of all stock option grants using the Black-Scholes option pricing model and recognize forfeitures as they occur. Estimating the fair value of equity 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 variables, including the fair value of the underlying common stock on the date of grant, the risk-free interest rate, the expected stock price volatility, the expected term of stock options, and the expected dividend yield. 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. See Note 7 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report for information concerning certain of the specific assumptions we used in applying the Black-Scholes option pricing model to determine the estimated fair value of our stock options granted the three months ended March 31, 2022 and 2021.
