On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers. The terms of the 2026 Notes are governed by an Indenture, or the Indenture, by and between Alarm.com Holdings, Inc. and U.S. Bank National Association, as trustee. The 2026 Notes are senior unsecured obligations that do not bear regular interest and the principal amount of the 2026 Notes will not accrete. The 2026 Notes may bear special interest under specified circumstances related to our failure to comply with our reporting obligations under the Indenture. Special interest, if any, will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2021. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs.

We may not redeem the 2026 Notes prior to January 20, 2024. We may redeem for cash, all or any portion of the 2026 Notes, at our option, on or after January 20, 2024, at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, if the last reported sale price of our common stock has been at least 130% of the conversion price for the 2026 Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. No sinking fund is provided for the 2026 Notes.

The 2026 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding August 15, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the 2026 Notes on each applicable trading day; (2) during the 5 business day period immediately after any 10 consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2026 Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the 2026 Notes on each such trading day; (3) if we call any or all of the 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the 2026 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events as set forth in the Indenture.

regardless of the foregoing conditions. Upon conversion, we may satisfy our conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is our current intent to settle the principal amount of the 2026 Notes with cash. The initial conversion rate for the 2026 Notes is 6.7939 shares of our common stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of $147.19 per share of our common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture. In addition, following certain corporate events that occur prior to the maturity date of the 2026 Notes or if we deliver a notice of redemption in respect of the 2026 Notes, we will, under certain circumstances, increase the conversion rate of the 2026 Notes for a holder who elects to convert its 2026 Notes (or any portion thereof) in connection with such a corporate event or convert its 2026 Notes called (or deemed called) for redemption during the related redemption period (as defined in the Indenture), as the case may be.

If we undergo a fundamental change (as defined in the Indenture), subject to certain exceptions and except as described in the Indenture, holders may require us to repurchase for cash all or any portion of their 2026 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

We used some of the proceeds to repay the $110.0 million outstanding principal balance under our credit facility and also used some of the proceeds to pay accrued interest, fees and expenses related to our credit facility (see the section titled "2017 Facility" below). We are using the remaining net proceeds from the issuance of the 2026 Notes for working capital and other general corporate purposes, which may include acquisitions or strategic investments in complementary businesses or technologies.

As discussed in Note 2, we adopted ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity" effective January 1, 2022, using a modified retrospective adoption method. Prior to the adoption of the standard, the 2026 Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that did not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2026 Notes. The equity component was recorded in additional paid-in capital and was not remeasured as it continued to meet the conditions for equity classification. The debt discount for conversion option, debt issuance costs and net carrying amount of the equity component was $77.2 million, $2.4 million and $74.8 million, respectively, as of December 31, 2021. The excess of the principal amount of the liability component over its carrying amount was amortized to interest expense over the contractual term of the 2026 Notes at an effective interest rate of 4.0%.

Prior to the adoption of ASU 2020-06, the difference between the book and tax treatment of the debt discount and debt issuance costs of the 2026 Notes resulted in a difference between the carrying amount and tax basis of the 2026 Notes. This taxable temporary difference resulted in the recognition of a $18.3 million net deferred tax liability which was recorded as an adjustment to additional paid-in capital during the three months ended March 31, 2021.

Upon adoption of ASU 2020-06 on January 1, 2022, we recombined the liability and equity components of the 2026 Notes assuming that the instrument was accounted for as only a liability from inception to the date of adoption. We also recombined the liability and equity components of the debt issuance costs. The issuance costs are presented as a deduction from the outstanding principal balance of the 2026 Notes and are amortized to interest expense using the effective interest method over the contractual term of the 2026 Notes at a rate of 0.6%.

As of December 31, 2022 and 2021, the fair value of our 2026 Notes was $411.5 million and $452.5 million, respectively. The fair value was determined based on the quoted price of the 2026 Notes in an inactive market on the last traded day of the quarter and has been classified as Level 2 in the fair value hierarchy. Based on the closing price of our common stock of $49.48 on the last trading day of the quarter, the if-converted value of the 2026 Notes did not exceed the principal amount of $500.0 million as of December 31, 2022.

On October 6, 2017, we entered into a $125.0 million senior secured revolving credit facility, or the 2017 Facility, with Silicon Valley Bank, or SVB, as administrative agent, PNC Bank, National Association, as documentation agent, and a syndicate of lenders. Upon entry into the 2017 Facility, we borrowed $72.0 million, which was used to repay the previously outstanding balance under our previous credit facility. The 2017 Facility was set to mature in October 2022 and included an option to further increase the borrowing capacity to $175.0 million with the consent of the lenders. Costs incurred in connection with the 2017 Facility were capitalized and were being amortized as interest expense over the term of the 2017 Facility. The 2017 Facility was secured by substantially all of our assets, including our intellectual property. On March 25, 2020, we borrowed $50.0 million under the 2017 Facility as a precautionary measure in order to provide financial flexibility in light of current uncertainty in the financial markets resulting from the COVID-19 pandemic. On January 20, 2021, we repaid the entire outstanding principal balance of $110.0 million of the 2017 Facility with proceeds from the 2026 Notes. The 2017 Facility was terminated on January 20, 2021 and we recognized an extinguishment loss of $0.2 million in other (expense) / income, net in our consolidated statements of operations during the year ended December 31, 2021 for previously capitalized debt issuance costs related to the 2017 Facility that were unamortized at the time of the termination of the 2017 Facility. There were no amounts outstanding under the 2017 Facility as of December 31, 2022 and 2021 as a result of the termination of the 2017 Facility on January 20, 2021.

The outstanding principal balance on the 2017 Facility accrued interest at a rate equal to, at our option, either (1) LIBOR, plus an applicable margin based on our consolidated leverage ratio, or (2) the highest of (a) the Wall Street Journal prime rate, (b) the Federal Funds rate plus 0.50%, or (c) LIBOR plus 1.00% plus an applicable margin based on our consolidated leverage ratio. During 2021, until the termination of the 2017 Facility on January 20, 2021, we elected for the outstanding principal balance to accrue interest at LIBOR plus 1.50%, LIBOR plus 1.75%, LIBOR plus 2.00%, and LIBOR plus 2.50% when our consolidated leverage ratio is less than 1.00:1.00, greater than or equal to 1.00:1.00 but less than 2.00:1.00, greater than or equal to 2.00:1.00 but less than 3.00:1.00 and greater than or equal to 3.00:1.00, respectively. The 2017 Facility also carried an unused line commitment fee of 0.20%.

We have various agreements that may obligate us to indemnify the other party to the agreement with respect to certain matters. Generally, these indemnification provisions are included in contracts arising in the normal course of business. Although we cannot predict the maximum potential amount of future payments that may become due under these indemnification agreements, we do not believe any potential liability that might arise from such indemnity provisions is probable or material.

On June 2, 2015, Vivint, Inc., or Vivint, filed a lawsuit against us in U.S. District Court, District of Utah, alleging that our technology directly and indirectly infringes six patents that Vivint purchased. Vivint is seeking permanent injunctions, enhanced damages and attorneys' fees. We answered the complaint on July 23, 2015. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. In 2017 and 2019, the U.S. Patent Trial and Appeal Board, or PTAB, issued final written decisions in inter partes reviews finding all or some of the claims in five of the asserted patents unpatentable. These decisions were affirmed on appeal. Discovery closed on October 29, 2021. Vivint has moved for partial summary judgment and Alarm.com has moved for summary judgment; both motions are pending decision. Vivint has also moved to assert previously abandoned claims from two of the patents in a new proceeding. We have opposed the motion. No trial date has been set.

Should Vivint prevail in proving Alarm.com infringes one or more of its patent claims, we could be required to pay damages of Vivint’s lost profits and/or a reasonable royalty for sales of our solution. Since all remaining patent claims in the litigation have expired, Vivint shall not be entitled to injunctive relief as a remedy in this matter. While we believe we have valid defenses to Vivint’s claims, any of these outcomes could result in a material adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

Further related to Vivint, on October 27, 2022, we filed a demand for arbitration of a dispute arising under the Patent Cross License Agreement between Alarm.com and Vivint executed in November 2013. Vivint has stopped paying license fees to Alarm.com under the agreement. Vivint has paid the required license fees to Alarm.com since the agreement was executed in November 2013. Alarm.com disputes Vivint's refusal of payment and is seeking continued payments of license fees in the arbitration, as well as interest and declaratory relief. There can be no assurance that Alarm.com will be successful in the arbitration proceedings. As a result of Vivint’s refusal to pay license fees under the agreement, which began during the fourth quarter of 2022, SaaS and license revenue and total revenue will decrease by approximately $6.0 million on a quarterly basis. We also believe that quarterly earnings and cash flow will be impacted by the aforementioned $6.0 million estimate, plus additional legal fees.

We also filed a lawsuit against Vivint on January 4, 2023 in U.S. District Court, Eastern District of Texas, alleging that Vivint infringes 15 of our patents. The case is docketed as No. 2:23-CV-0004-JRG-RSP (E.D. Tex.). We are seeking compensatory and enhanced damages, a permanent injunction and other relief. Vivint’s response to the complaint is due February 27, 2023.

On January 10, 2022, EcoFactor, Inc., or EcoFactor, filed a lawsuit against us in U.S. District Court, District of Oregon, alleging Alarm.com’s products and services directly and indirectly infringe five U.S. patents owned by EcoFactor. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. We moved to dismiss the case for failure to state a claim on March 28, 2022. EcoFactor had previously asserted two of the same patents against us in an October 2019 complaint with the U.S. International Trade Commission, or ITC. In July 2021, the ITC found in favor of Alarm.com. EcoFactor appealed the decision but withdrew its appeal in December 2021. Two of the other three asserted patents are currently in ex parte reexamination proceedings at the PTO, and all claims of the third were found unpatentable by the PTAB in inter partes review on April 18, 2022. Also on April 18, 2022, the district court stayed the case at the request of the parties pending the disposition of other proceedings involving the asserted patents, including the reexamination proceedings.

Should EcoFactor prevail in its lawsuit we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to EcoFactor’s claims, the outcome of these legal claims cannot be predicted with certainty and any of these outcomes could result in an adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

On July 22, 2021, Causam Enterprises, Inc., or Causam, filed a lawsuit against us in U.S. District Court, Western District of Texas, alleging that Alarm.com’s smart thermostats infringe four U.S. patents owned by Causam. Causam is seeking preliminary and permanent injunctions, enhanced damages and attorneys’ fees. We have not yet responded to the complaint. On September 3, 2021, the court issued an order staying the lawsuit until the ITC investigation described below is finally resolved.

On July 28, 2021, Causam filed a complaint with the ITC naming Alarm.com Incorporated, Alarm.com Holdings, Inc., and EnergyHub, Inc., among others, as proposed respondents. The complaint alleges infringement of the same four patents Causam asserted in district court. Causam is seeking a permanent limited exclusion order and permanent cease and desist order. On August 27, 2021, the ITC instituted an investigation into Causam’s allegations naming Alarm.com Incorporated, Alarm.com Holdings, Inc., EnergyHub Inc. and others as respondents. We answered the complaint on October 4, 2021. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. An evidentiary hearing in the investigation was held from June 28, 2022 through July 1, 2022. On February 16, 2023, the ITC issued a final decision in favor of Alarm.com and EnergyHub. Causam has until April 17, 2023 to file an appeal of the decision in federal court.

Should Causam prevail in its district court lawsuit we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to Causam’s claims, the outcome of these legal claims cannot be predicted with certainty, and any of these outcomes could result in an adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

On February 25, 2021, Vivint filed a lawsuit against ADT LLC a/k/a ADT LLC of Delaware d/b/a ADT Security Services in U.S. District Court, District of Utah, alleging that ADT Pulse, Control, and Blue each infringe one or more patents owned by Vivint. Vivint is seeking damages and attorneys’ fees. Vivint filed a second amended complaint on March 8, 2022. ADT answered the second amended complaint on March 22, 2022, asserted defenses based on non-infringement and invalidity of all five asserted patents and counterclaimed for declaratory judgement of invalidity of all five asserted patents. Two of the asserted patents are under inter partes review at the PTAB. On June 17, 2022, the court entered an order staying the case in view of the pending proceedings before the PTAB, with the exception of certain discovery of source code.

Should Vivint prevail on the claims that one or more elements of ADT’s products infringe, we could be required to indemnify ADT for damages in the form of a reasonable royalty or ADT could be enjoined from making, using and selling our solution if a license or other right to continue selling our technology is not made available or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. The outcome of these legal claims cannot be predicted with certainty. We believe there are valid defenses to the claims made by Vivint. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

Further, on November 4, 2022 and January 13, 2023, IOT Innovations LLC sued our service provider Monitronics International, Inc. d/b/a Brinks in U.S. District Court, Eastern District of Texas, alleging patent infringement of certain products and services sold by Monitronics. Monitronics filed a Motion to Dismiss the first-filed case on January 24, 2023. The cases are in the preliminary stages and the extent of Alarm.com’s indemnify obligations to Monitronics has not yet been determined, however should IOT Innovations prevail on the claims that one or more elements of Monitronics’ products or services infringe, we could be required to indemnify Monitronics for damages in the form of a reasonable royalty or Monitronics could be enjoined from making, using and selling our solution if a license or other right to continue selling our technology is not made available or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. The outcome of these legal claims cannot be predicted with certainty. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

Other than the preceding matters, we are not a party to any lawsuit or proceeding that, in the opinion of management, is reasonably possible or probable of having a material adverse effect on our financial position, results of operations or cash flows. We reserve for contingent liabilities based on ASC 450, "Contingencies," when it is determined that a liability, inclusive of defense costs, is probable and reasonably estimable. Litigation is subject to many factors that are difficult to predict, so there can be no assurance that, in the event of a material unfavorable result in one or more claims, we will not incur material costs.
