Accounting Standards and Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include Castlight and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. In the opinion of management, the information herein reflects all adjustments, consisting only of normal recurring adjustments except as otherwise noted, considered necessary for a fair statement of results of operations, financial position, stockholders’ equity and cash flows. The results for the interim periods presented are not necessarily indicative of the results expected for any future period. The following information should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018

Other than described below, there have been no changes to our significant accounting policies described in our Annual Report that have had a material impact on our consolidated financial statements and related notes.
Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. These estimates include, but are not limited to the determination of:

Variable consideration included in the transaction price of the Company’s contracts with customers;
The standalone selling price of the performance obligations in the Company’s contracts with customers;
Assumptions used in the valuation of certain equity awards;
The amortization period for deferred commissions and deferred professional services costs; and
Assumptions used in the calculation of right-of-use (“ROU”) assets and lease liabilities for operating leases, including lease terms and the Company’s incremental borrowing rate.

Actual results could differ from those estimates, and such differences could be material to the Company’s consolidated financial position and results of operations.

Summary of Significant Accounting Policies

Leases

The Company determines if an arrangement is a lease and its classification at lease inception. Operating lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the lease commencement date to compute the present value of lease payments when the implicit rate is not readily determinable. ROU assets are measured at lease inception based on the initial measurement of the lease liability, plus any prepaid lease amounts, less any lease incentives. The Company does not recognize ROU assets or lease liabilities for leases with a term of 12 months or less. Lease terms do not include options to extend or terminate the lease unless it is reasonably certain that the option will be exercised. Generally, lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company's lease agreements have both lease and non-lease components. The Company has elected to account for the non-lease components of its leases as part of their related lease components.

Concentrations of Risk and Significant Customers

No single direct customer accounted for more than 10% of total revenue during the three and six months ended June 30, 2019 or more than 10% of accounts receivable as of June 30, 2019. Castlight had one channel partner that represented approximately 26% and 25% of total revenue during the three and six months ended June 30, 2019, respectively, and approximately 37% of accounts receivable as of June 30, 2019.

Recently Adopted Accounting Pronouncements

Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases, and subsequent amendments ("ASC 842") using the modified retrospective method, and chose to apply the provisions at the beginning of the period of adoption. The guidance requires lessees to put all leases that have a term of more than one year on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-of-use ("ROU") asset for the right to use the underlying asset for the lease term. 

As a result of the adoption of ASC 842 as of January 1, 2019, reporting periods beginning on and after January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue to be reported in accordance with prior accounting guidance under ASC 840. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 an operating lease ROU asset of approximately $17.3 million and an operating lease liability of approximately $20.7 million. The difference between the operating lease ROU asset and lease liability resulted from the reclass of the deferred rent liability to the operating lease ROU asset. The standard did not materially impact the Company’s condensed consolidated statement of operations and had no impact on the cash flows. See Note 10 - Leases for more information on leases.

Recently Issued Accounting Pronouncements
    
The Company considers the applicability and impact of all ASUs issued by the FASB. The Company determined that the ASUs issued by the FASB during the six months ended June 30, 2019 are either not applicable or are expected to have minimal impact on the Company's condensed consolidated financial results.

The Company sells to customers based in the United States through direct sales and indirect channels. Indirect channel revenue represented approximately 27% and 10% of the Company’s total revenue for the three months ended June 30, 2019 and 2018, respectively. Indirect channel revenue represented approximately 27% and 10% of the Company’s total revenue for the six months ended June 30, 2019 and 2018, respectively.

Deferred revenue as of June 30, 2019 and December 31, 2018 was $21.5 million and $21.2 million, respectively. Contract assets as of June 30, 2019 and December 31, 2018 were $1.2 million and $1.0 million, respectively.

$11.3 million and $16.5 million of revenue was recognized during the three months ended June 30, 2019 and 2018, respectively, that was included in the Company’s deferred revenue balances at the beginning of the respective periods. $16.0 million and $22.6 million of revenue was recognized during the six months ended June 30, 2019 and 2018, respectively, that was included in the Company’s deferred revenue balances at the beginning of the respective periods.

The Company recorded favorable cumulative catch-up adjustments to revenue of $0.5 million during the three months ended June 30, 2019 and unfavorable cumulative catch-up adjustments to revenue of $0.8 million during the three months ended June 30, 2018, arising from changes in estimates of transaction price. The Company recorded favorable cumulative catch-up adjustments to revenue of $1.9 million during the six months ended June 30, 2019 and unfavorable cumulative catch-up adjustments to revenue of $0.6 million during the six months ended June 30, 2018, arising from changes in estimates of transaction price.

The aggregate balance of remaining performance obligations from non-cancelable contracts with customers as of June 30, 2019 was $127.3 million. The Company expects to recognize approximately 70% of this balance over the next 12 months, with the remaining balance recognized thereafter. Remaining performance obligations are defined as deferred revenue and amounts yet to be billed for the non-cancelable portion of contracts.

Fair Value Measurements
Fair Value Measurements
The Company measures its financial assets and liabilities at fair value at each reporting period using a fair value hierarchy that requires that the Company maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:
Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2—Include other inputs that are directly or indirectly observable in the marketplace.
Level 3—Unobservable inputs that are supported by little or no market activity.
The fair value of marketable securities included in the Level 2 category is based on observable inputs, such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. These values were obtained from a third-party pricing service and were evaluated using pricing models that vary by asset class and may incorporate available trade, bid and other market information and price quotes from well-established third party pricing vendors and broker-dealers.
There have been no changes in valuation techniques in the periods presented. There were no significant transfers between fair value measurement levels as of June 30, 2019 and December 31, 2018. As of June 30, 2019 and December 31, 2018, there were no securities within Level 3 of the fair value hierarchy.
The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis using the above input categories (in thousands):

Term Loan

In connection with the Company’s acquisition of Jiff, on April 3, 2017, the Company, Jiff and Silicon Valley Bank (the “Bank”) agreed to refinance the existing term loan facility owed by Jiff to the Bank (the “Loan Agreement”) for approximately $5.6 million (the “Term Loan”). The Term Loan requires interest-only payments for the period May 2017 through September 2018, followed by 36 monthly payments of principal and interest. Obligations under the Term Loan accrue interest at a floating per annum rate equal to the greater of (A) the prime rate as published in the money rates section of The Wall Street Journal (“Prime Rate”) minus 1% or (B) 0%. Interest on the Term Loan is payable monthly. The maturity date of the Term Loan is September 1, 2021.

In addition to principal and interest payments, the Company is also required to pay $0.5 million as final payment on the earlier of maturity, termination or prepayment of the Term Loan. The Company accrues for the final payment over the life of the Term Loan using the effective interest method.

Net Loss per Share
Net 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 net loss per share is computed by giving effect to all potential shares of common stock, including outstanding stock options and warrants, to the extent dilutive. Basic and diluted net loss per share was the same for each period presented as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive.
Net loss is allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the year have been distributed. As the liquidation and dividend rights are identical, the net loss is allocated on a proportionate basis.

Accounting Policies [Abstract]  
Basis of Presentation and Principles of Consolidation
Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include Castlight and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. In the opinion of management, the information herein reflects all adjustments, consisting only of normal recurring adjustments except as otherwise noted, considered necessary for a fair statement of results of operations, financial position, stockholders’ equity and cash flows. The results for the interim periods presented are not necessarily indicative of the results expected for any future period. The following information should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018

Other than described below, there have been no changes to our significant accounting policies described in our Annual Report that have had a material impact on our consolidated financial statements and related notes.
Use of Estimates
Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. These estimates include, but are not limited to the determination of:

Variable consideration included in the transaction price of the Company’s contracts with customers;
The standalone selling price of the performance obligations in the Company’s contracts with customers;
Assumptions used in the valuation of certain equity awards;
The amortization period for deferred commissions and deferred professional services costs; and
Assumptions used in the calculation of right-of-use (“ROU”) assets and lease liabilities for operating leases, including lease terms and the Company’s incremental borrowing rate.

Actual results could differ from those estimates, and such differences could be material to the Company’s consolidated financial position and results of operations.

Leases
Leases

The Company determines if an arrangement is a lease and its classification at lease inception. Operating lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the lease commencement date to compute the present value of lease payments when the implicit rate is not readily determinable. ROU assets are measured at lease inception based on the initial measurement of the lease liability, plus any prepaid lease amounts, less any lease incentives. The Company does not recognize ROU assets or lease liabilities for leases with a term of 12 months or less. Lease terms do not include options to extend or terminate the lease unless it is reasonably certain that the option will be exercised. Generally, lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company's lease agreements have both lease and non-lease components. The Company has elected to account for the non-lease components of its leases as part of their related lease components.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements
Recently Adopted Accounting Pronouncements

Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases, and subsequent amendments ("ASC 842") using the modified retrospective method, and chose to apply the provisions at the beginning of the period of adoption. The guidance requires lessees to put all leases that have a term of more than one year on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-of-use ("ROU") asset for the right to use the underlying asset for the lease term. 

As a result of the adoption of ASC 842 as of January 1, 2019, reporting periods beginning on and after January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue to be reported in accordance with prior accounting guidance under ASC 840. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 an operating lease ROU asset of approximately $17.3 million and an operating lease liability of approximately $20.7 million. The difference between the operating lease ROU asset and lease liability resulted from the reclass of the deferred rent liability to the operating lease ROU asset. The standard did not materially impact the Company’s condensed consolidated statement of operations and had no impact on the cash flows. See Note 10 - Leases for more information on leases.

Recently Issued Accounting Pronouncements
    
The Company considers the applicability and impact of all ASUs issued by the FASB. The Company determined that the ASUs issued by the FASB during the six months ended June 30, 2019 are either not applicable or are expected to have minimal impact on the Company's condensed consolidated financial results.
