Use of Non-GAAP Financial Measures
To supplement its Condensed Consolidated Financial Statements presented in accordance with generally accepted accounting principles, or GAAP, ServiceSource provides investors with non-GAAP gross profit, net income (loss), net income (loss) per diluted share and Adjusted EBITDA. A reconciliation of these non-GAAP financial measures to the closest GAAP financial measure is presented in the financial tables below under the heading, "GAAP to Non-GAAP Reconciliation."
ServiceSource believes non-GAAP financial information provided in this release can assist investors in understanding and assessing its on-going core operations and prospects for the future and provides an additional tool for investors to use in comparing ServiceSource's financial results with other companies in the industry, many of which present similar non-GAAP financial measures to investors.
Non-GAAP gross profit consists of gross profit plus adjustments to stock-based compensation, amortization of internally-developed software and amortization of purchased intangible assets.
Non-GAAP net income (loss) consists of net income (loss) plus stock-based compensation, amortization of internally-developed software, amortization of purchased intangible assets, restructuring and other related costs, amortization of contract acquisition costs related to the initial adoption of Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASC 606”), impairment loss on investment securities, gain on sale of cost basis equity investment, litigation reserve and non-cash interest expense and applying an income tax rate of 26.5% and 40.0% as of December 31, 2018 and December 31, 2017, respectively, on non-GAAP adjustments as well as the impact of normalizing the effective income tax rate. Stock-based compensation expense is expected to vary depending on the number of new grants issued, changes in the Company's stock price, stock market volatility, expected option lives and risk-free interest rates, all of which are difficult to estimate.
EBITDA consists of net income (loss) plus provision for income tax (benefit) expense, interest and other income (expense), net and depreciation and amortization. Adjusted EBITDA consists of EBITDA plus non-cash stock-based compensation, amortization of contract acquisition costs related to the initial adoption of ASC 606, gain on sale of cost basis equity investment, impairment loss on investment securities, restructuring and other related costs and litigation reserve.
These non-GAAP measures should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP.

Footnotes to GAAP to Non-GAAP Reconciliation                
(A) Stock-based compensation. Included in our GAAP presentation of cost of revenue and operating expenses, stock-based compensation consists of expenses for stock options, stock unit awards and purchase rights under our stock purchase plan. We exclude stock-based compensation expense from our non-GAAP measures because some investors may view it as not reflective of our core operating performance as it is a non-cash expense.
(B) Amortization of internally-developed software. Included in our GAAP presentation of cost of revenue and operating expenses, amortization of internally-developed software reflects non-cash expense for software developed or obtained for internal use. We exclude these expenses from our non-GAAP measures because we believe they are not indicative of our core operating performance.
(C) Amortization of purchased intangibles. Included in our GAAP presentation of gross margin and operating expenses is amortization of purchased intangible assets. We believe amortization of acquisition-related intangible assets, such as amortization of costs associated with an acquired company’s research and development efforts, trade names and customer relationships, are items arising from pre-acquisition activities and determined at the time of an acquisition. Although these intangible assets are continually evaluated for impairment, amortization of purchased intangibles is a static expense and not typically affected by operations during any particular period.
(D) Restructuring and other related costs. Included in our GAAP presentation, we incurred expenses related to our restructuring effort to better align our cost structure with current revenue levels. Restructuring and other expenses consist primarily of stock-based compensation related to the accelerated vesting of certain equity awards, employees' severance payments, related employee benefits, related legal fees, asset impairment charges and charges related to leases and other contract termination costs. These are one-time in nature costs that are not indicative of our core operating performance.
(E) Amortization of contract acquisition costs - ASC 606 initial adoption. Upon adoption of ASC 606 using the modified retrospective approach, we capitalized approximately $3.3 million of previously expensed sales commissions from 2015, 2016 and 2017. Amortization of these amounts are included in our GAAP presentation as sales and marketing expense. We believe this non-cash amortization expense is not related to or indicative of our ongoing operating performance.
(F) Impairment loss on investment securities. We liquidated our investment securities during the first half of 2018 to have sufficient cash on hand to repay our $150.0 million convertible notes due August 1, 2018. Based on our decision to sell these investment securities, we determined an other-than-temporary impairment occurred as of March 31, 2018 and recorded an impairment loss, which represented the difference between the investment securities' amortized cost basis and fair value. This charge is not related to or indicative of ongoing operating performance.
(G) Gain on sale of cost basis equity investment. In 2013, we made an equity investment in a private company for $4.5 million, which represented less than 5% of the outstanding equity of the company. Based on unfavorable growth trends and declining financial performance of this private company, we determined that the investment was fully impaired and recorded a $2.3 million and $2.2 million impairment charge in the third and fourth quarters of 2016, respectively. During the year ended December 31, 2017, we sold the investment for $2.1 million in cash and recorded the proceeds as a gain. This gain is not related to or indicative of our ongoing core operating performance.
(H) Non-cash interest expense. Under GAAP, we recognize interest expense at the effective interest rate which includes interest costs related to the amortization of debt issuance costs and debt premiums or discounts. The difference between the effective interest rate and the contractual interest rate is excluded from our assessment of our operating performance because we believe this non-cash expense is not indicative of ongoing operating performance. We believe that the exclusion of the non-cash interest expense provides investors a view of our core operating performance.
(I) Income tax effect on non-GAAP adjustments as well as the impact of normalizing the effective income tax rate. This adjusts (i) the provision for income taxes to reflect the effect of the non-GAAP items A, B, C, D, E, F, G, H and K noted above on our non-GAAP net income; and (ii) the income tax rate to a normalized effective tax rate of 26.5% for the three months and year ended December 31, 2018 and 40.0% for the three months and year ended December 31, 2017, respectively.
(J) Shares used in calculating diluted net income per share on a non-GAAP basis. Due to year to date GAAP net losses, the share count for basic and diluted earnings per share is the same.
(K) Litigation reserve. The Company records a contingent liability when it is probable that a loss has been incurred and the amount is reasonably estimable in accordance with accounting for contingencies. As of December 31, 2018, the Company has accrued a $3.8 million reserve relating to our potential liability for currently pending disputes. These reserves are one-time in nature charges that are not indicative of our core operating performance.
