NOTE 1 - DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business

Square, Inc. (together with its subsidiaries, Square or the Company) creates tools that help sellers start, run, and grow their businesses. Square enables sellers to accept card payments and also provides reporting and analytics, next-day settlement, and chargeback protection. Square's point-of-sale software and other business services help sellers manage inventory, locations, and employees; access financing; engage customers; and grow sales. Square Cash is an easy way for businesses and individuals to send and receive money, and Caviar is a food ordering service for restaurants. Square was founded in 2009 and is headquartered in San Francisco, with offices in the United States, Canada, Japan, Australia, Ireland, and the United Kingdom.

Basis of Presentation

The accompanying interim condensed consolidated financial statements of the Company are unaudited. These interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) and the applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The  December 31, 2016 condensed consolidated balance sheet was derived from the audited financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

The accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company's consolidated financial position, results of operations, comprehensive loss, and cash flows for the interim periods. All intercompany transactions and balances have been eliminated in consolidation. The interim results for the  three and six months ended  June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending  December 31, 2017 , or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures About Market Risk," and the Consolidated Financial Statements and notes thereto included in Items 7, 7A, and 8, respectively, in the Company's Annual Report on Form 10-K for the year ended  December 31, 2016 .

Reclassifications and other adjustments

As a result of the Company's adoption of Accounting Standards Update (ASU) No. 2016-18,  Restricted Cash, on January 1, 2017, the Company reclassified changes in restricted cash balances from investing activities in the statement of cash flows to changes in cash, cash equivalents and restricted cash. For the six months ended June 30, 2016 , $8.5 million was reclassified from cash outflows from investing activities to changes in cash, cash equivalents and restricted cash.

The presentation of changes in customer funds in the statement of cash flows for the six months ended June 30, 2016 has also been revised for the correction of an immaterial error that was identified during the fourth quarter of 2016 whereby the Company had previously misclassified and reported certain customer funds as cash and cash equivalents rather than classifying these customer funds as a component of current assets impacting operating activities. The effect of the revision was to decrease the amount of net cash used in operating activities for the six months ended June 30, 2016 by $3.2 million and increase cash and cash equivalents as of June 30, 2016 by that same amount. Net cash provided by operating activities for the year ended December 31, 2016 and cash and cash equivalents as of December 31, 2016 were not misstated.

The Company has reclassified certain prior period balances to conform to the current period presentation. In particular the Company has combined the Customer funds obligation and Customers payable into a single caption called Customer payable on the consolidated balance sheet. This classification change was made because both accounts reflect customer amounts that are held by Square that are obligations to the customer.

Use of Estimates

The preparation of the Company's consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as related disclosure of contingent assets and liabilities. Actual results could differ from the Company's estimates. To the extent that there are material differences between these estimates and actual results, the Company's financial condition or operating results will be materially affected. The Company bases its estimates on past experience and other assumptions that the Company believes are reasonable under the circumstances, and the Company evaluates these estimates on an ongoing basis.

Significant estimates, judgments, and assumptions in these consolidated financial statements include, but are not limited to, those related to revenue recognition, accrued transaction losses, valuation of the debt component of convertible senior notes, valuation of loans held for sale, goodwill and intangible assets, income and other taxes, and share-based compensation.

Concentration of Credit Risk

For the three and six months ended  June 30, 2017 , the Company had no customer that accounted for greater than 10% of total net revenue. For the three and six months ended  June 30, 2016 , the Company had no customer other than Starbucks that accounted for greater than 10% of total net revenue. During the fourth quarter of 2016, Starbucks completed its previously announced transition to another payments solution provider. Accordingly, the Company does not expect transaction-based revenue from Starbucks in the future.

The Company had three third-party processors that represented approximately 44% , 42% , and 10% of settlements receivable as of June 30, 2017 . The same three parties represented approximately 52% , 35% , and 10% of settlements receivable as of December 31, 2016 .

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, marketable securities, settlements receivables, customer funds, and loans held for sale. The associated risk of concentration for cash and cash equivalents and restricted cash is mitigated by banking with creditworthy institutions. At certain times, amounts on deposit exceed federal deposit insurance limits. The associated risk of concentration for marketable securities is mitigated by holding a diversified portfolio of highly rated investments. Settlements receivable are amounts due from well-established payment processing companies and normally take one or two business days to settle which mitigates the associated risk of concentration. The associated risk of concentration for loans held for sale is partially mitigated by credit evaluations that are performed prior to facilitating the offering of loans and ongoing performance monitoring of the Company's loan customers.

Significant Accounting Policies

Except for the adoption of ASU 2016-18, Restricted Cash, described above, there have been no material changes to the Company's significant accounting policies during the  six months ended  June 30, 2017 , as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 .

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09,  Revenue from Contracts with Customers , and issued subsequent amendments to the initial guidance within ASU 2015-04, ASU 2016-08, ASU 2016-10, ASU 2016-12, and ASU 2016-20. The new guidance will replace all current U.S. GAAP guidance on this topic and eliminate all industry specific guidance. The core principal of this new guidance is that revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration for which the Company expects to be entitled in exchange for those goods or services. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company does not plan to early adopt the guidance. The guidance can be adopted either through the full retrospective approach which requires restatement of all periods presented or through a modified retrospective approach which requires a cumulative effect adjustment as of the date of adoption. The modified retrospective approach also requires additional disclosures, during the year of adoption, of the impact of the new guidance to each of the financial statements line items and qualitative explanation of the significant changes between the reported results under the new revenue guidance and the previous revenue guidance. The Company plans to apply the modified retrospective approach in the year of adoption of this guidance and is currently assessing the impact that the adoption of the guidance will have on the consolidated financial statements and

related disclosures. The Company is also assessing any financial reporting system changes that would be necessary to implement the new guidance.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, as part of its simplification initiative. The current guidance requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less a normal profit margin. Under the new guidance, inventory is measured at the lower of cost and net realizable value, which would eliminate the other two options that currently exist for market replacement cost and net realizable value less a normal profit margin. The amendment is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with early adoption permitted. The Company adopted this new guidance on January 1, 2017, and it did not have any effect on the consolidated financial statements and related disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance is intended to improve the recognition, measurement, presentation, and disclosure of financial instruments. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted with certain restrictions. The Company is currently evaluating the impact this new guidance may have on the consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases , which will require, among other items, lessees to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The Company does not plan to early adopt this guidance. The Company's operating leases primarily comprise of office spaces, with the most significant leases relating to corporate headquarters in San Francisco and an office in New York. Based on the Company's initial assessment of its current leases and potential, the Company does not anticipate the adoption of this guidance to have a material impact on its operating results. The Company will continue to evaluate the impact of recording right to use assets and related liabilities on its consolidated balance sheets.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting ,

which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with early adoption permitted. The Company adopted this new guidance on January 1, 2017. As part of the adoption, the Company elected to account for forfeitures as they occur. As this guidance requires a modified retrospective approach when eliminating the forfeiture rate, the Company recorded an adjustment of $ 0.7 million to increase accumulated deficit and additional paid-in capital as of January 1, 2017. With respect to classification of excess tax benefits on the Statement of Cash Flows, the Company has elected to apply this guidance on a prospective basis. Thus, the prior periods have not been adjusted. The remaining areas of simplification in this guidance did not have an impact on the consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments , which requires measurement and recognition of expected credit losses for financial assets held. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this new guidance may have on the consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. This guidance addresses several cash flow issues with the objective of reducing the existing diversity in practice. Specific issues addressed in this guidance include, but are not limited to, debt prepayment or extinguishment costs, contingent consideration payments made after a business combination and application of the predominance principle. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The amendments should be applied retrospectively. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements and related disclosures.

In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other Than Inventory , which amends existing guidance on the recognition of current and deferred income tax impacts for intra-entity asset transfers other than inventory. The current guidance requires companies to defer the income tax effects of intercompany transfers of all assets, until the asset has been sold to an outside party whereas the new guidance will not allow the deferral of income tax effects of

intercompany transfers of assets except for inventory. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The amendments in this guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact this new guidance may have on the consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash , which provides guidance on the classification of restricted cash to be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts on the statement of cash flows. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company early adopted this guidance on January 1, 2017, and adjusted its condensed consolidated statements of cash flow for each of the periods presented.

In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business . The amendment seeks to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, intangible assets and consolidation. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The amendments should be applied prospectively on or after the effective dates. The Company is currently evaluating the impact this new guidance may have on the consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment . This guidance modified the concept of impairment assessment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. This standard should be adopted when the Company performs its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted. The amendments should be applied on a prospective basis. The Company does not expect the adoption of this guidance to have a material the impact on the consolidated financial statements and related disclosures.

In March 2017, the FASB issued ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities, which amends the amortization period for certain purchased callable debt securities held at a premium, shortening such period to the earliest call date. This standard is effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The amendments in this guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact this new guidance may have on the consolidated financial statements and related disclosures.

In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting, which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The amendments should be applied on a prospective basis. The Company is currently evaluating the impact this new guidance may have on the consolidated financial statements and related disclosures.

NOTE 2 - RESTRICTED CASH

As of both June 30, 2017  and  December 31, 2016 , restricted cash of $22.1 million is related to pledged cash deposited into savings accounts at the financial institutions that process the Company's sellers' payment transactions and as collateral pursuant to an agreement with the originating bank for the Company's loan product. The Company uses the restricted cash to secure letters of credit with the financial institution to provide collateral for cash flow timing differences in the processing of these payments and loans. The Company has recorded this amount as a current asset on the condensed consolidated balance sheets due to the short-term nature of these cash flow timing differences and that there is no minimum time frame during which the cash must remain restricted.

As of both June 30, 2017  and  December 31, 2016 , the remaining restricted cash of $14.6 million is primarily related to cash deposited into money market funds that is used as collateral pursuant to multi-year lease agreements entered into in 2012 and 2014 (see Note 15 ). The Company has recorded this amount as a non-current asset on the condensed consolidated balance sheets as the terms of the related leases extend beyond one year.

NOTE 3 - FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company measures its cash equivalents and short-term and long-term investments at fair value. The Company classifies its cash equivalents and short-term and long-term investments within Level 1 or Level 2 of the fair value hierarchy because the Company values these investments using quoted market prices or alternative pricing sources and models utilizing market observable inputs.

The Company's financial assets and liabilities that are measured at fair value on a recurring basis are classified as follows (in thousands):

The carrying amounts of certain financial instruments, including cash equivalents, settlements receivable, customer funds, accounts payable, customers payable, and settlements payable, approximate their fair values due to their short-term nature.

The Company estimates the fair value of its convertible senior notes based on their last actively traded prices (Level 1) or market observable inputs (Level 2). The estimated fair value and carrying value of the convertible senior notes were as follows (in thousands):

Loans held for sale are recorded at the lower of cost or fair value. To determine the fair value of loans, the Company utilizes industry-standard valuation modeling, such as discounted cash flow models, applied to the loans held for sale, to arrive at an estimate of fair value.

A summary of loans disclosed at fair value on a recurring basis is as follows (in thousands):

If applicable, the Company will recognize transfers into and out of levels within the fair value hierarchy at the end of the reporting period in which the actual event or change in circumstance occurs. During the three and six months ended June 30, 2017 and 2016 , the Company did not have any transfers in or out of Level 1, Level 2, or Level 3 assets or liabilities.

NOTE 4 - INVESTMENTS

The Company determines the appropriate classification of its investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its marketable securities as available-for-sale.

The Company's short-term and long-term investments as of  June 30, 2017  are as follows (in thousands):

The Company's short-term and long-term investments as of  December 31, 2016  are as follows (in thousands):

For the periods presented, gains or losses realized on the sale of investments were not material. Investments are reviewed periodically to identify possible other-than-temporary impairments. As the Company has the ability and intent to hold these investments with unrealized losses until a recovery of fair value, or for a reasonable period of time sufficient for the recovery of fair value, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired for any of the periods presented.

The contractual maturities of the Company's short-term and long-term investments as of  June 30, 2017  are as follows (in thousands):

NOTE 5 - PROPERTY AND EQUIPMENT, NET

Depreciation and amortization expense on property and equipment was  $7.2 million and $14.5 million for the three and six months ended June 30, 2017 , respectively. Depreciation and amortization expense on property and equipment was  $6.9 million and $13.3 million for the three and six months ended June 30, 2016 , respectively.

NOTE 6 - GOODWILL

Goodwill is recorded when the consideration paid for an acquisition of a business exceeds the fair value of identifiable net tangible and intangible assets acquired. As of June 30, 2017 and December 31, 2016 , goodwill was $58.0 million and $57.2 million , respectively.

The Company performs a goodwill impairment test annually on December 31 and more frequently if events and circumstances indicate that the asset might be impaired. For the periods presented, the Company had recorded no impairment charges.

NOTE 7 - ACQUIRED INTANGIBLE ASSETS

The following table presents the detail of acquired intangible assets as of the periods presented (in thousands):

The weighted average amortization periods for acquired patents, acquired technology, and customer intangible assets are approximately 13 years , four years , and nine years , respectively.

NOTE 10 - INDEBTEDNESS

Revolving Credit Facility

In November 2015 , the Company entered into a revolving credit agreement with certain lenders, which extinguished the prior revolving credit agreement and provided for a $375.0 million revolving secured credit facility maturing in November 2020 . This revolving credit agreement is secured by certain tangible and intangible assets.

Loans under the 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 an adjusted LIBOR rate for a one-month interest period, in each case plus a margin ranging from 0.00% to 1.00% , or (ii) an adjusted LIBOR rate plus a margin ranging from 1.00% to 2.00% . This margin is determined based on the Company's total leverage ratio for the preceding four fiscal quarters. The Company is obligated to pay other customary fees for a credit facility of this size and type including an annual administrative agent fee of $0.1 million and an unused commitment fee of 0.15% . To date no funds have been drawn under the credit facility, with $375.0 million remaining available. The Company paid $0.1 million and $0.3 million in unused commitment fees during the three and six months ended June 30, 2017 and 2016 , respectively. As of June 30, 2017 , the Company was in compliance with all financial covenants associated with this credit facility.

Convertible Senior Notes

On March 6, 2017, the Company issued an aggregate principal amount of $ 400.0 million  of convertible senior notes (Notes) and an additional 10% or $ 40.0 million pursuant to the exercise in full of the option to the initial purchasers to cover over-allotments. The 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 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 Notes, which is equivalent to an initial conversion price of approximately $ 22.95  per share of Class A common stock. Holders may convert their Notes at any time prior to the close of business on the business day immediately preceding December 1, 2021 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2017 (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 Notes) per $1,000 principal amount of 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 Notes) or a transaction resulting in the Company's Class A common stock converting into other securities or property or assets.  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 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. It is the Company's current intent and policy to settle conversions through combination settlement with a specified dollar amount of $ 1,000 per $ 1,000 principal amount of notes.

In accounting for the issuance of the Notes, the Company separated the 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 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 Notes at an effective interest rate of 5.34% over the contractual terms of the Notes.

Debt issuance costs related to the Notes comprised of discounts and commissions payable to the initial purchasers of $ 11.0 million and third party offering costs of $ 0.8 million . The Company allocated the total amount incurred to the liability and equity components of the 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.

Convertible Note Hedge and Warrant Transactions

In connection with the offering of the Notes, the Company entered into convertible note hedge transactions with certain financial institutions (Counterparties) whereby the Company has the option to purchase a total of approximately 19.2 million shares of its Class A common stock at a price of approximately $ 22.95 per share. The total cost of the convertible note hedge transactions was $ 92.1 million . In addition, the Company sold warrants to the Counterparties whereby the Counterparties have the option to purchase a total of approximately 19.2 million shares of the Company's Class A common stock at a price of

approximately $ 31.18 per share. The Company received $ 57.2 million in cash proceeds from the sale of these warrants. Taken together, the purchase of the convertible note hedges and sale of the warrants are intended to offset any actual dilution from the conversion of the Notes and to effectively increase the overall conversion price from approximately $ 22.95 per share to approximately $ 31.18 per share. As these instruments are considered indexed to the Company's own stock and are considered equity classified, the convertible note hedges and warrants are recorded in stockholders' equity, are not accounted for as derivatives and are not remeasured each reporting period. The net costs incurred in connection with the convertible note hedge and warrant transactions were recorded as a reduction to additional paid-in capital on the condensed consolidated balance sheets.

NOTE 11 - ACCRUED TRANSACTION LOSSES

The Company is exposed to transaction losses due to chargebacks as a result of fraud or uncollectibility.

NOTE 12 - INCOME TAXES

The Company recorded an income tax expense of $0.5 million and $1.0 million for the three and six months ended June 30, 2017 , respectively, compared to income tax expense of $0.3 million and $0.7 million for the three and six months ended June 30, 2016 , respectively. The income tax expense recorded for the three and six months ended June 30, 2017 and June 30, 2016 was primarily due to state and foreign income tax expense.

The Company's effective tax rate was (3.0)% and (3.3)% for the three and six months ended June 30, 2017 , respectively, compared to an effective tax rate of (1.2)% and (0.5)% for the three and six months ended June 30, 2016 , respectively. The difference between the effective tax rate and the federal statutory tax rate for the three and six months ended June 30, 2017 and June 30, 2016 primarily relates to the valuation allowance on the Company's deferred tax assets.

The Company's effective tax rate may be subject to fluctuation during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as the mix of forecasted pre-tax earnings in the various jurisdictions in which the Company operates, valuation allowances against deferred tax assets, the recognition and de-recognition of tax benefits related to uncertain tax positions, and changes in or the interpretation of tax laws in jurisdictions where the Company conducts business.

As of June 30, 2017 , the Company retains a full valuation allowance on its deferred tax assets in the U.S. and certain foreign jurisdictions. The realization of the Company's deferred tax assets depends primarily on its ability to generate taxable income in future periods. The amount of deferred tax assets considered realizable in future periods may change as management continues to reassess the underlying factors it uses in estimating future taxable income.

The tax provision for the three and six months ended June 30, 2017 and June 30, 2016 , was calculated on a jurisdiction basis. The Company estimated the foreign income tax provision using the effective income tax rate expected to be applicable for the full year.

NOTE 13 - STOCKHOLDERS' EQUITY

The changes in total stockholders' equity were as follows (in thousands):

Warrants

On February 24, 2017, the Company and Starbucks entered into a Warrant Cancellation and Payment Agreement pursuant to which the Company paid Starbucks cash consideration of approximately $ 54.8 million in return for the termination of the Warrant to Purchase Stock dated August 7, 2012, as amended, that provided Starbucks with the right to purchase an aggregate of 9,456,955 shares of the Company's common stock.

In conjunction with the Notes offering, the Company sold warrants whereby the Counterparties have the option to purchase a total of approximately 19.2 million shares of the Company's Class A common stock at a price of $ 31.18 per share. The Company received $ 57.2 million in cash proceeds from the sale of these warrants. See Note 10 , Indebtedness , for more details on this transaction.

Stock Plans

The Company maintains two share-based employee compensation plans: the 2009 Stock Plan (2009 Plan) and the 2015 Equity Incentive Plan (2015 Plan). The 2015 Plan serves as the successor to the 2009 Plan. The 2015 Plan became effective as of November 17, 2015. Outstanding awards under the 2009 Plan continue to be subject to the terms and conditions of the 2009 Plan. Since November 17, 2015, no additional securities have been nor will be in the future issued under the 2009 Plan.

Under the 2015 Plan, shares of the Company's Class A common stock are reserved for the issuance of incentive and nonstatutory stock options, restricted stock awards, restricted stock units (RSUs), performance shares, and stock bonuses to qualified employees, directors, and consultants. The shares may be granted at a price per share not less than the fair market value at the date of grant. Initially, 30,000,000 shares were reserved under the 2015 Plan, and any shares subject to options or other similar awards granted under the 2009 Plan that expire, are forfeited, are repurchased by the Company, or otherwise terminate unexercised, will become available under the 2015 Plan. The number of shares available for issuance under the 2015 Plan will be increased on the first day of each fiscal year, in an amount equal to the least of (i) 40,000,000 shares, (ii) 5% of the outstanding shares on the last day of the immediately preceding fiscal year, or (iii) such number of shares determined by the Company's board of directors. As of June 30, 2017 , the total number of shares subject to stock options and RSUs outstanding under the 2015 Plan was 25,989,237 , and 47,378,192 shares were available for future issuance. As of June 30, 2017 , the total number of shares subject to stock options and RSUs outstanding under the 2009 Plan was 52,709,658 .

A summary of stock option activity for the six months ended June 30, 2017 is as follows (in thousands, except share and per share data):

Share-Based Compensation

The fair value of stock options and employee stock purchase plan rights are estimated on the date of grant using the Black-Scholes-Merton option valuation model.

The fair value of stock options granted was estimated using the following weighted-average assumptions:

As a result of the Company's adoption of ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting , the Company elected to account for forfeitures as they occur. As this guidance requires a modified retrospective approach when eliminating the forfeiture rate, the Company recorded an adjustment of $ 0.7 million to increase accumulated deficit and additional paid-in capital as of January 1, 2017.

The following table summarizes the effects of share-based compensation on the Company's condensed consolidated statements of operations (in thousands):

The Company recorded $1.2 million and $3.0 million of share-based compensation expense related to the Company's 2015 Employee Stock Purchase Plan during the three and six months ended  June 30, 2017 , respectively, compared to $1.5 million and $3.0 million for the three and six months ended June 30, 2016 , respectively, which are included in the table above.

The Company capitalized $0.7 million and $1.2 million of share-based compensation expense related to capitalized software costs during the three and six months ended  June 30, 2017 , respectively, compared to $0.9 million for both the three and six months ended June 30, 2016 .

As of June 30, 2017 , there was $386.0 million of total unrecognized compensation cost related to outstanding stock options that is expected to be recognized over a weighted-average period of 2.93 years .

NOTE 14 - LOSS PER SHARE

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted loss per share is the same as basic loss per share for all years presented because the effects of potentially dilutive items were anti-dilutive given the Company's net loss.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

The following potential common shares were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented (in thousands):

Additionally, since the Company expects to settle the principal amount of its outstanding Notes in cash, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread will have a dilutive impact on diluted net income per share of common stock when the average market price of the Company's common stock for a given period exceeds the conversion price of $ 22.95 per share for the Notes, which has not occurred as of June 30, 2017.

NOTE 15 - COMMITMENTS AND CONTINGENCIES

Operating and Capital Leases
