On October 7, 2020, the Company completed the issuance and sale of $750 million aggregate principal amount of its 4.625% senior notes due 2030 (the“4.625% Senior Notes”) in a private placement offering exempt from the registration requirements of the Securities Act of 1933. The Company received proceeds of $742.7 million after deducting the initial purchasers’ discounts, commissions and offering expenses. The net proceeds were used to redeem all of its outstanding 6.0% Senior Notes due in 2025 and, remaining net proceeds were available for general corporate purposes which may include acquisitions and the repurchase or redemption of other outstanding indebtedness.

The 4.625% Senior Notes bear interest at a rate of 4.625% per annum, payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2021. The 4.625% Senior Notes mature on October 15, 2030, and are senior unsecured obligations of the Company which are guaranteed, jointly and severally, on an unsecured basis by certain of the Company’s existing and future domestic direct and indirect wholly-owned subsidiaries (collectively, the “Guarantors”). If the Company or any of its restricted subsidiaries acquires or creates a domestic restricted subsidiary, other than an Insignificant Subsidiary (as defined in the indenture pursuant to which the 4.625% Senior Notes were issued (the “Indenture”)), after the issue date, or any Insignificant Subsidiary ceases to fit within the definition of Insignificant Subsidiary, such restricted subsidiary is required to unconditionally guarantee, jointly and severally, on an unsecured basis, the Company’s obligations under the 4.625% Senior Notes.

The Company may redeem some or all of the 4.625% Senior Notes at any time on or after October 15, 2025 at specified redemption prices plus accrued and unpaid interest, if any, to, but excluding the redemption date. Before October 15, 2023, and following certain equity offerings, the Company also may redeem up to 40% of the 4.625% Senior Notes at a price equal to 104.625% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding the redemption date. The Company may make such redemption only if, after such redemption, at least 50% of the aggregate principal amount of the 4.625% Senior Notes remains outstanding. In addition, at any time prior to October 15, 2025, the Company may redeem some or all of the 4.625% Senior Notes at a price equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus an applicable “make-whole” premium.

The Indenture contains covenants that restrict the Company’s ability to (i) pay dividends or make distributions on the Company’s common stock or repurchase the Company’s capital stock; (ii) make certain restricted payments; (iii) create liens or enter into sale and leaseback transactions; (iv) enter into transactions with affiliates; (v) merge or consolidate with another company; and (vi) transfer and sell assets. These covenants contain certain exceptions. Restricted payments are applicable only if the Company and subsidiaries designated as restricted subsidiaries have a net leverage ratio of greater than 3.5 to 1.0. In addition, if such net leverage ratio is in excess of 3.5 to 1.0, the restriction on restricted payments is subject to various exceptions, including the total aggregate amount not exceeding the greater of (A) $250 million and (B) 50.0% of EBITDA for the most recently ended four fiscal quarter period ended immediately prior to such date for which internal financial statements are available. The Company is in compliance with its debt covenants as of September 30, 2021.

On September 24, 2021, the Company announced the commencement of a cash tender offer for up to a maximum aggregate amount of $90.0 million of its 4.625% Senior Notes. Accordingly, as of September 30, 2021, the Company has classified $83.3 million of its 4.625% Senior Notes as short-term on its Condensed Consolidated Balance Sheet as of September 30, 2021.The remainder of the 4.625% Senior Notes are presented as long-term debt, net of deferred issuance costs, on the Condensed Consolidated Balance Sheet as of September 30, 2021.

On June 10, 2014, the Company issued $402.5 million aggregate principal amount of 3.25% convertible senior notes due June 15, 2029 (the “3.25% Convertible Notes”). The 3.25% Convertible Notes bore interest at a rate of 3.25% per annum, payable semiannually in arrears on June 15 and December 15 of each year. Beginning with the six-month interest period commencing on June 15, 2021, the Company had to pay contingent interest on the 3.25% Convertible Notes during any six-month interest period if the trading price per $1,000 principal amount of the 3.25% Convertible Notes for each of the five trading days immediately preceding the first day of such interest period equaled or exceeded $1,300. Any contingent interest payable on the 3.25% Convertible Notes would have been in addition to the regular interest payable on the 3.25% Convertible Notes.

In connection with the spin-off of Consensus, the Company called its 3.25% Convertible Notes for redemption and on August 2, 2021, the Company redeemed in full all of its outstanding 3.25% Convertible Notes. During the three and nine months ended September 30, 2021, the Company satisfied its conversion obligation by paying the principal of $399.6 million and $402.4 million, respectively, in cash and issued 3,031,817 and 3,050,850 shares of the Company’s common stock. respectively (see Note 13 - Stockholders’ Equity).

The 3.25% Convertible Notes were carried at face value less any unamortized debt discount and debt issuance costs. The fair value of the 3.25% Convertible Notes at each balance sheet date was determined based on recent quoted market prices or dealer quotes for the 3.25% Convertible Notes, which are Level 1 inputs (see Note 7 - Fair Value Measurements). If such information was not available, the fair value was determined using cash-flow models of the scheduled payments discounted at market interest rates for comparable debt without the conversion feature. As of September 30, 2021 and December 31, 2020, the estimated fair value of the 3.25% Convertible Notes was approximately zero and $593.1 million, respectively.

On November 15, 2019, the Company issued $550.0 million aggregate principal amount of 1.75% convertible senior notes due November 1, 2026 (the “1.75% Convertible Notes”). the Company received proceeds of $537.1 million in cash, net of purchasers’ discounts and commissions and other debt issuance costs. A portion of the net proceeds were used to pay off all amounts outstanding under the then-existing Credit Facility. The 1.75% Convertible Notes bear interest at a rate of 1.75% per annum, payable semiannually in arrears on May 1 and November 1 of each year, beginning on May 1, 2020. The 1.75% Convertible Notes will mature on November 1, 2026, unless earlier converted or repurchased.

Holders may surrender their 1.75% Convertible Notes for conversion at any time prior to the close of business on the business day immediately preceding July 1, 2026 only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on March 31, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding the calendar quarter is greater than 130% of the applicable conversion price of the 1.75% Convertible Notes on each such applicable trading day; (ii) during the five business day period following any 10 consecutive trading day period in which the trading price per $1,000 principal amount of 1.75% Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the applicable conversion rate on each such trading day; or (iii) upon the occurrence of specified corporate events. On or after July 1, 2026, and prior to the close of business on the business day immediately preceding the maturity date, holders may convert all or any portion of their notes at any time, regardless of the foregoing circumstances. The Company will settle conversions of the 1.75% Convertible Notes by paying or delivering, as the case may be, cash, shares of the Company’s common stock or a combination thereof at the Company’s election. The Company currently intends to satisfy its conversion obligation by paying and delivering a combination of cash

and shares of the Company’s common stock. Holders of the notes will have the right to require the Company to repurchase for cash all or any portion of their notes upon the occurrence of certain corporate events, subject to certain conditions. During the third quarter of 2021 and the fourth quarter of 2020, the last reported sale price of the Company’s common stock did not meet the conversion price threshold requirements of the 1.75% Convertible Notes. Therefore, the net carrying amount of the 1.75% Convertible Notes is classified as long-term debt on the Condensed Consolidated Balance Sheets.

As of September 30, 2021, the conversion rate is 7.9864 shares of the Company’s common stock for each $1,000 principal amount of 1.75% Convertible Notes, which represents an conversion price of approximately $125.21 per share of the Company’s common stock. The conversion rate is subject to adjustment for certain events as set forth in the indenture governing the 1.75% Convertible Notes, but will not be adjusted for accrued interest. In addition, upon the occurrence of a “Make-Whole Fundamental Change” (as defined in the 1.75% Convertible Note Indenture), the Company will increase the conversion rate for a holder that elects to convert its 1.75% Convertible Notes in connection with such a corporate event in certain circumstances.

The 1.75% Convertible Notes are the Company’s general senior unsecured obligations and rank: (i) senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 1.75% Convertible Notes; (ii) equal in right of payment to the Company’s existing and future indebtedness that is not so subordinated, including its existing 3.25% Convertible Notes due 2029; (iii) effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and (iv) structurally junior to all existing and future indebtedness and other liabilities incurred by the Company’s subsidiaries, including the then-existing 6.0% Senior Notes due 2025.

In accordance with ASC 470-20, Debt with Conversion and Other Options, convertible debt that can be settled for cash is required to be separated into the liability and equity component at issuance, with each component assigned a value. The value assigned to the liability component is the effective fair value, as of the issuance date, of similar debt without the conversion feature. The difference between the cash proceeds and estimated fair value of the liability component, representing the value of the conversion premium assigned to the equity component, is recorded as a debt discount on the issuance date. This debt discount is amortized to interest expense using the effective interest method over the period from the issuance date through the maturity date of November 1, 2026.

The Company estimated the borrowing rates of similar debt without the conversion feature at origination to be 5.5% for the 1.75% Convertible Notes and determined the debt discount to be $118.9 million. As a result, a conversion premium after tax of $88.1 million (net of $2.8 million of the deferred issuance costs) are recorded in additional paid-in capital. The aggregate debt discount is amortized as interest expense over the period from the issuance date through the maturity date of November 1, 2026, which management believes is the expected life of the 1.75% Convertible Notes using an interest rate of 5.5%. As of September 30, 2021, the remaining period over which the unamortized debt discount will be amortized is 5.1 years.

In connection with the issuance of the 1.75% Convertible Notes, the Company incurred $12.9 million of deferred issuance costs, which primarily consisted of the underwriters’ discount, legal and other professional service fees. Of the total deferred issuance costs incurred, $10.1 million of such deferred issuance costs were attributable to the liability component and are recorded within other assets and are being amortized to interest expense through the maturity date. The remaining $2.8 million of the deferred issuance costs were netted with the equity component in additional paid-in capital at the issuance date. As of September 30, 2021, the unamortized deferred issuance costs were $8.0 million.

The 1.75% Convertible Notes are carried at face value less any unamortized debt discount and issuance costs. The fair value of the 1.75% Convertible Notes at each balance sheet date is determined based on recent quoted market prices or dealer quotes for the 1.75% Convertible Notes, which are Level 1 inputs (see Note 7 - Fair Value Measurements). If such information is not available, the fair value is determined using cash-flow models of the scheduled payments discounted at market interest rates for comparable debt without the conversion feature. As of September 30, 2021 and December 31, 2020, the estimated fair value of the 1.75% Convertible Notes was approximately $692.9 million and $569.7 million, respectively.

On April 7, 2021, the Company entered into a $100.0 million Credit Agreement (the “Credit Agreement”). Subject to customary conditions, the Company may, from time to time, request increases in the commitments under the Credit Agreement in an aggregate amount up to $250.0 million, for a total aggregate commitment of up to $350.0 million. The final maturity of the Credit Facility will occur on April 7, 2026.

On June 2, 2021, June 21, 2021, August 20, 2021 and September 16, 2021, the Company entered into First, Second, Third and Fourth Amendments (together the “Amendments”) to the Credit Agreement. The Amendments (i) provided for the issuance of a senior secured term loan under the Credit Agreement, in an aggregate principal amount of $485.0 million (the “Bridge Loan Facility”), (ii) permitted the spin-off of the Company’s cloud fax business into a new publicly traded company, and (iii) provided for certain other changes to the Credit Agreement.

The Bridge Loan Facility bore interest at a rate per annum equal to (i) initially upon funding of the loan, either a base rate plus 2.00%, or a LIBOR rate plus 3.00%, (ii) from six months after the funding date of the Bridge Loan Facility until twelve months after the funding date of the Bridge Loan Facility, either a base rate plus 2.50%, or a LIBOR rate plus 3.50%, and (iii) from twelve months after the funding date of the Bridge Loan Facility until repayment of the Bridge Loan Facility, either a base rate plus 3.00% or a LIBOR rate plus 4.00%. The Bridge Loan Facility was to mature on the date that is 364 days after the funding date of the Bridge Loan Facility, with two automatic extensions, each for an additional three months, if SEC approval of the spin-off transaction was still outstanding. As of September 30, 2021, the Company had drawn on the full amount of the Bridge Loan Facility with $485.0 million outstanding. The proceeds of the Bridge Loan Facility were used to redeem the Company’s 3.25% Convertible Notes. As of September 30, 2021, the estimated fair value of the Bridge Loan Facility was $485.0 million. Refer to Note 18 - Subsequent Events for information on the extinguishment of the Bridge Loan subsequent to September 30, 2021 in connection with the spin-off of the cloud fax business.

The Company was required to pay a funding fee of 0.50% of the aggregate principal amount of Bridge Loan Facility made on the funding date thereof, as well as a duration fee of 0.25% of the aggregate principal amount of outstanding Bridge Loans on the sixth month anniversary of the funding of the Bridge Loans, and a fee of 0.50% of the aggregate principal amount of outstanding Bridge Loans on each of the nine-month, twelve-month and fifteen-month anniversaries of the funding of the Bridge Loans.
