INDEBTEDNESS | INDEBTEDNESS Revolving Credit Facility In May 2020, the Company entered into a revolving credit agreement with certain lenders, which provided a $500.0 million senior unsecured revolving credit facility (the "2020 Credit Facility") maturing in May 2023. On May 28, 2020, the Company amended the credit agreement for the 2020 Credit Facility (the "Credit Agreement") to permit the Company’s wholly owned subsidiary, Square Capital, LLC (“Square Capital”), to incur indebtedness in an aggregate principal amount of up to $500.0 million pursuant to the Paycheck Protection Program Liquidity Facility (“PPPLF”) authorized under the Federal Reserve Act of 1913. In connection with its convertible debt offerings in November 2020, the Company entered into a second amendment to the Credit Agreement on November 9, 2020 to permit convertible debt in an aggregate principal amount not to exceed $3.6 billion. On January, 28, 2021, the Company entered into a third amendment to the Credit Agreement to increase the amount of indebtedness that Square Capital is permitted to incur pursuant to the PPPLF from an aggregate principal amount of up to $500 million to an aggregate principal amount of up to $1.0 billion. The Credit Agreement also contains a financial covenant that requires the Company to maintain a quarterly minimum liquidity amount (consisting of the sum of Unrestricted cash and Cash Equivalents plus Marketable Securities, each as defined in the Credit Agreement) of at least $250.0 million, tested on a quarterly basis. The Company is obligated to pay customary fees for a credit facility of this size and type including an unused commitment fee of 0.15%. To date no funds have been drawn and no letters of credit have been issued under the 2020 Credit Facility. As of March 31, 2021, $500.0 million remained available for draw. The Company incurred $0.2 million and $0.1 million in unused commitment fees during the three months ended March 31, 2021 and 2020, respectively. As of March 31, 2021, the Company was in compliance with all financial covenants associated with the 2020 Credit Facility. Loans under the 2020 Credit Facility bear interest at the Company's option of (i) a base rate based on the highest of the prime rate, the federal funds rate plus 0.50%, and the adjusted LIBOR rate plus 1.00%, in each case, plus a margin ranging from 0.25% to 0.75% or (ii) an adjusted LIBOR rate plus a margin ranging from 1.25% to 1.75%. The Credit Agreement includes provisions allowing the Company to replace or update LIBOR with a replacement rate. The margin is determined based on the Company’s total leverage ratio, as defined in the Credit Agreement. The Credit Agreement also contains customary affirmative and negative covenants typical for a financing of this type that, among other things, restricts the Company and certain of its subsidiaries’ ability to incur additional indebtedness, create liens, merge or consolidate or make certain dispositions, pay dividends and make distributions, enter into restrictive agreements, enter into agreements with affiliates, and make certain investments and acquisitions. Paycheck Protection Program Liquidity Facility On June 2, 2020, Square Capital was approved to borrow under the PPPLF with the Federal Reserve Bank of San Francisco (“First PPPLF Agreement”) at an annual interest rate of 0.35%. The PPPLF extends credit to eligible financial institutions that have originated or purchased PPP loans. Advances under the PPPLF are non-recourse and are secured by a pledge of PPP loans held by Square Capital. The maturity date of any PPPLF loan will be the maturity date of the PPP loans pledged to secure such PPPLF loan. The maturity date of any PPPLF loan will be accelerated on and to the extent of (i) the date of any loan forgiveness reimbursement by the SBA for any PPP loan securing such PPPLF loan; or (ii) the date of purchase by the SBA from Square Capital of any PPP loan securing such PPPLF loan to realize on the SBA’s guarantee of such PPP loan. The maturity date of all PPPLF loans shall be accelerated upon the occurrence of certain events of default by Square Capital, including but not limited to the failure to comply with a requirement of the PPPLF agreement or any representation, warranty, or covenant of Square Capital under the PPPLF agreement being inaccurate on or as of the date it is deemed to be made or on any date on which an PPPLF loan remains outstanding. The Company can also at its option prepay the advances in full or in part without penalty. Square Capital also shall prepay PPPLF loans so that the amount of any PPPLF loans outstanding does not exceed the outstanding amount of PPP loans pledged to secure such PPPLF loans. On January 29, 2021, Square Capital entered into a second PPPLF agreement with the Federal Reserve Bank of San Francisco (“Second PPPLF Agreement”) to secure additional credit collateralized by loans from the subsequent rounds of the PPP program in an aggregate principal amount of up to $1.0 billion under both PPPLF agreements. As of March 31, 2021, $764.2 million of PPPLF advances were outstanding and collateralized by the same value of PPP loans. Convertible Senior Notes due in 2026 and 2027 On November 13, 2020, the Company issued an aggregate principal amount of $1.15 billion of convertible senior notes comprised of $575.0 million of convertible senior notes due 2026 ("2026 Notes") and $575.0 million of convertible senior notes due 2027 ("2027 Notes"). The 2026 Notes mature on May 1, 2026, unless earlier converted or repurchased, and bears a zero rate of interest. The 2027 Notes mature on November 1, 2027, unless earlier converted or repurchased, and bear interest at a rate of 0.25% payable semi-annually on May 1 and November 1 of each year. Both the 2026 Notes and 2027 Notes are convertible at an initial conversion rate of 3.3430 shares of the Company's Class A common stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $299.13 per share of Class A common stock. Holders may convert their relevant series of notes at any time prior to the close of business on the business day immediately preceding February 1, 2026 and August 1, 2027 for the 2026 Notes and 2027 Notes, respectively, only under the following circumstances: (1) during any calendar quarter, commencing after the calendar quarter ending on March 31, 2021 (and only during such calendar quarter), if the last reported sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the "measurement period") in which the trading price (as defined in the indenture governing the 2026 Notes and 2027 Notes) per $1,000 principal amount of 2026 Notes and 2027 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 Class A common stock and the conversion rate on each such trading day; (3) if the Company calls any or all of the 2026 Notes and 2027 Notes for redemption, such relevant series of notes called for redemption may be converted at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events, including certain distributions, the occurrence of a fundamental change (as defined in the indenture governing the 2026 Notes and 2027 Notes) or a transaction resulting in the Company’s Class A common stock converting into other securities or property or assets. In addition, upon occurrence of the specified corporate events prior to the maturity date, the Company would increase the conversion rate for a holder who elects to convert their relevant series of notes in connection with such an event in certain circumstances. On or after February 1, 2026 in the case of the 2026 Notes, and on or after August 1, 2027 in the case of the 2027 Notes, up until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder of the relevant series of notes may convert all or any portion of its 2026 Notes or 2027 Notes regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its Class A common stock, or a combination of cash and shares of its Class A common stock, at the Company’s election. The circumstances required to allow the holders to convert their 2026 Notes and 2027 Notes were not met during the three months ended March 31, 2021. On or after November 5, 2023 for the 2026 Notes, and on or after November 5, 2024 for the 2027 Notes, the Company may redeem all or a portion of each series of notes for cash at its option, if the last reported sale price of the Company's Class A common stock has been at least 130% of the conversion price for the relevant series of 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 the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2026 Notes and 2027 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. In accounting for the issuance of the 2026 Notes and 2027 Notes, prior to the adoption of ASU No. 2020-06, the Company separated the relevant series of notes 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 does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was $198.0 million and was determined by deducting the fair value of the liability component from the par value of the 2026 Notes and the 2027 Notes. The equity component was not re-measured as long as it continued to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount ("debt discount") was amortized to interest expense at an effective interest rate of 3.35% and 3.66% for the 2026 Notes and 2027 Notes, respectively. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the separation of the debt and equity components and accounted for the Notes wholly as debt. The Company also reversed the amortization of the debt discount, with a cumulative adjustment to retained earnings on the adoption date. Debt issuance costs related to the 2026 Notes and 2027 Notes were comprised of discounts and commissions payable to the initial purchasers of $17.5 million and third party offering costs of $1.0 million. Prior to the adoption of ASU No. 2020-06, the Company allocated the total amount incurred to the liability and equity components of the 2026 Notes and 2027 Notes based on their relative values. Issuance costs attributable to the liability component were $15.4 million and were amortized to interest expense using the effective interest method. Issuance costs attributable to the equity component were netted with the equity component in stockholders’ equity. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the allocation of the issuance costs to the equity component and accounted for the entire amount as debt issuance cost that will be amortized as interest expense at an effective interest rate of 0.49% and 0.30% for each of the respective terms of the 2026 Notes and 2027 Notes, respectively, with a cumulative adjustment to retained earnings on the adoption date. Upon adoption of ASU No. 2020-06, the difference between the estimated fair value and the carrying value upon conversion will be accounted for as a reduction to the related debt issuance costs, with the remainder recognized as additional paid in capital to reflect the par value of the shares issued. As of March 31, 2021, there has been no principal converted on either the 2026 Notes or 2027 Notes. As of March 31, 2021, the if-converted value of the 2026 Notes and 2027 Notes did not exceed the outstanding principal amount. Convertible Senior Notes due in 2025 On March 5, 2020, the Company issued an aggregate principal amount of $1.0 billion of convertible senior notes ("2025 Notes"). The 2025 Notes mature on March 1, 2025, unless earlier converted or repurchased, and bear interest at a rate of 0.1250% payable semi-annually on March 1 and September 1 of each year. The 2025 Notes are convertible at an initial conversion rate of 8.2641 shares of the Company's Class A common stock per $1,000 principal amount of 2025 Notes, which is equivalent to an initial conversion price of approximately $121.01 per share of Class A common stock. Holders may convert their 2025 Notes at any time prior to the close of business on the business day immediately preceding December 1, 2024 only under the following circumstances: (1) during any calendar quarter, commencing after the calendar quarter ending on June 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the "measurement period") in which the trading price (as defined in the indenture governing the 2025 Notes) per $1,000 principal amount of 2025 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 Class A common stock and the conversion rate on each such trading day; (3) if the Company calls any or all of the 2025 Notes for redemption, such 2025 Notes called for redemption may be converted at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events, including certain distributions, the occurrence of a fundamental change (as defined in the indenture governing the 2025 Notes) or a transaction resulting in the Company’s Class A common stock converting into other securities or property or assets. In addition, upon occurrence of the specified corporate events prior to the maturity date, the Company would increase the conversion rate for a holder who elects to convert their 2025 Notes in connection with such an event in certain circumstances. On or after December 1, 2024, up until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or any portion of its 2025 Notes regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its Class A common stock, or a combination of cash and shares of its Class A common stock, at the Company’s election. The Company may redeem for cash all or any part of the 2025 Notes, at its option, on or after March 5, 2023, if the last reported sale price of the Company's Class A common stock has been at least 130% of the conversion price for the 2025 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 the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2025 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. The circumstances to allow the holders to convert their 2025 Notes were met in the first quarter of 2021. In accounting for the issuance of the 2025 Notes, prior to the adoption of ASU No. 2020-06, the Company separated the 2025 Notes 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 does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was $154.6 million and was determined by deducting the fair value of the liability component from the par value of the 2025 Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount ("debt discount") is amortized to interest expense over the term of the 2025 Notes at an effective interest rate of 3.81% over the contractual terms of the 2025 Notes. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the separation of the debt and equity components and accounted for the 2025 Notes wholly as debt. The Company also reversed the amortization of the debt discount, with a cumulative adjustment to retained earnings on the adoption date. Debt issuance costs related to the 2025 Notes were comprised of discounts and commissions payable to the initial purchasers of $14.3 million and third party offering costs of $0.9 million. Prior to the adoption of ASU No. 2020-06, the Company allocated the total amount incurred to the liability and equity components of the 2025 Notes based on their relative values. Issuance costs attributable to the liability component were $12.8 million and will be amortized to interest expense using the effective interest method over the contractual term. Issuance costs attributable to the equity component were netted with the equity component in stockholders’ equity. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the allocation of the issuance costs to the equity component and accounted for the entire amount as debt issuance cost that will be amortized as interest expense over the remaining term at an effective interest rate of 0.43% for the 2025 Notes with a cumulative adjustment to retained earnings on the adoption date. Upon adoption of ASU No. 2020-06, the difference between the estimated fair value and the carrying value upon conversion will be accounted for as a reduction to the related debt issuance costs, with the remainder recognized as additional paid in capital to reflect the par value of the shares issued. As of March 31, 2021, there has been no principal converted on the 2025 Notes. As of March 31, 2021, the if-converted value of the 2025 Notes exceeded the outstanding principal amount by $876.4 million. Convertible Senior Notes due in 2023 On May 25, 2018, the Company issued an aggregate principal amount of $862.5 million of convertible senior notes ("2023 Notes"). The 2023 Notes mature on May 15, 2023, unless earlier converted or repurchased, and bear interest at a rate of 0.50% payable semi-annually on May 15 and November 15 of each year. The 2023 Notes are convertible at an initial conversion rate of 12.8456 shares of the Company's Class A common stock per $1,000 principal amount of 2023 Notes, which is equivalent to an initial conversion price of approximately $77.85 per share of Class A common stock. Holders may convert their 2023 Notes at any time prior to the close of business on the business day immediately preceding February 15, 2023 only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter), if the last reported sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the "measurement period") in which the trading price (as defined in the indenture governing the 2023 Notes) per $1,000 principal amount of 2023 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 Class A common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events, including certain distributions, the occurrence of a fundamental change (as defined in the indenture governing the 2023 Notes) or a transaction resulting in the Company’s Class A common stock converting into other securities or property or assets. On or after February 15, 2023, up until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or any portion of its 2023 Notes regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its Class A common stock, or a combination of cash and shares of its Class A common stock, at the Company’s election. The Company will reevaluate this policy from time to time as conversion notices are received from holders of the 2023 Notes. The circumstances to allow the holders to convert their 2023 Notes were met in the fourth quarter of 2020 and continued to be met through March 31, 2021. As of March 31, 2021, the aggregate principal amount of 2023 Notes converted by certain holders of the 2023 Notes was immaterial. In accounting for the issuance of the 2023 Notes, prior to the adoption of ASU No. 2020-06, the Company separated the 2023 Notes 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 does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was $155.3 million and was determined by deducting the fair value of the liability component from the par value of the 2023 Notes. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount ("debt discount") is amortized to interest expense over the term of the 2023 Notes at an effective interest rate of 4.69% over the contractual terms of the 2023 Notes. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the separation of the debt and equity components and accounted for the 2023 Notes wholly as debt. The Company also reversed the amortization of the debt discount, with a cumulative adjustment to retained earnings on the adoption date. Debt issuance costs related to the 2023 Notes comprised of discounts and commissions payable to the initial purchasers of $6.0 million and third party offering costs of $0.8 million. Prior to the adoption of ASU No. 2020-06, the Company allocated the total amount incurred to the liability and equity components of the 2023 Notes based on their relative values. Issuance costs attributable to the liability component were $5.6 million and will be amortized to interest expense using the effective interest method over the contractual term. Issuance costs attributable to the equity component were netted with the equity component in stockholders’ equity. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the allocation of the issuance costs to the equity component and accounted for the entire amount as debt issuance cost that will be amortized as interest expense over the remaining term at an effective interest rate of 0.66% for the 2023 Notes with a cumulative adjustment to retained earnings on the adoption date. Upon adoption of ASU No. 2020-06, the difference between the estimated fair value and the carrying value upon conversion will be accounted for as a reduction to the related debt issuance costs, with the remainder recognized as additional paid in capital to reflect the par value of the shares issued. As of March 31, 2021, there was an immaterial amount of principal converted on the 2023 Notes. As of March 31, 2021, the if-converted value of the 2023 Notes exceeded the outstanding principal amount by $1.7 billion. Convertible Senior Notes due in 2022 On March 6, 2017, the Company issued an aggregate principal amount of $440.0 million of convertible senior notes ("2022 Notes"). The 2022 Notes mature on March 1, 2022, unless earlier converted or repurchased, and bear interest at a rate of 0.375% payable semi-annually on March 1 and September 1 of each year. The 2022 Notes are convertible at an initial conversion rate of 43.5749 shares of the Company's Class A common stock per $1,000 principal amount of 2022 Notes, which is equivalent to an initial conversion price of approximately $22.95 per share of Class A common stock.

On or after December 1, 2021, up until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or any portion of its 2022 Notes regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its Class A common stock, or a combination of cash and shares of its Class A common stock, at the Company’s election. The circumstances required to allow the holders to convert their 2022 Notes were met in the fourth quarter of 2017 and continued to be met through March 31, 2021. As of March 31, 2021, certain holders of the 2022 Notes have converted an aggregate principal amount of $435.3 million of their Notes, of which $3.8 million was converted during the three months ended March 31, 2021. The Company has settled the conversions through a combination of $219.4 million in cash and issuance of 16.3 million shares of the Company's Class A common stock. The conversions during the three months ended March 31, 2021 were settled entirely in shares of the Company's Class A common stock. The Company will reevaluate this policy from time to time as conversion notices are received from holders of the 2022 Notes. In accounting for the issuance of the 2022 Notes, prior to the adoption of ASU No. 2020-06, the Company separated the 2022 Notes 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 does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was $86.2 million and was determined by deducting the fair value of the liability component from the par value of the 2022 Notes. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. The debt discount is amortized to interest expense over the term of the 2022 Notes at an effective interest rate of 5.34% over the contractual terms of the 2022 Notes. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the separation of the debt and equity components and accounted for the 2022 Notes wholly as debt.

Prior to the adoption of ASU No. 2020-06, the Company allocated the total amount incurred to the liability and equity components of the 2022 Notes based on their relative values. Issuance costs attributable to the liability component were $9.4 million and will be amortized to interest expense using the effective interest method over the contractual term. Issuance costs attributable to the equity component were netted with the equity component in stockholders’ equity. Upon adoption of ASU No. 2020-06 on January 1, 2021, the Company reversed the allocation of the issuance costs to the equity component and accounted for the entire amount as debt issuance cost that will be amortized as interest expense over the remaining term at an effective interest rate of 0.93% for the 2022 Notes with a cumulative adjustment to retained earnings on the adoption date. Prior to the adoption of ASU No. 2020-06, the debt component associated with the 2022 Notes that were converted was accounted for as an extinguishment of debt, with the Company recording loss on extinguishment as the difference between the estimated fair value and the carrying value of such 2022 Notes. The equity component associated with the 2022 Notes that were converted was accounted for as a reacquisition of equity upon the conversion of such 2022 Notes. Upon adoption of ASU No. 2020-06, the difference between the estimated fair value and the carrying value upon conversion was accounted for as a reduction to the related debt issuance costs, with the remainder recognized as additional paid in capital to reflect the par value of the shares issued. There no longer is a gain or loss on extinguishment of debt recognized upon conversion, as the debt is settled in equity. As of March 31, 2021, the if-converted value of the 2022 Notes exceeded the outstanding principal amount by $41.9 million. The net carrying amount of the Notes were as follows (in thousands): Principal outstanding Unamortized debt issuance costs Net carrying value March 31, 2021 2027 Notes $ 575,000 $ (8,790) $ 566,210 2026 Notes 575,000 (8,652) 566,348 2025 Notes 1,000,000 (11,918) 988,082 2023 Notes 862,500 (2,925) 859,575 2022 Notes 4,698 (24) 4,674 Total $ 3,017,198 $ (32,309) $ 2,984,889 As discussed above, upon the adoption of ASU No. 2020-06, the Company reversed the separation of the debt and equity components of the notes, and accounted for the Notes wholly as debt.
