1Annual Recurring Revenue (ARR). MobileIron will transition from reporting Annualized Recurring Revenue, which was defined as the recurring revenue recognized during a quarter multiplied by four, to reporting Annual Recurring Revenue per the definition and detail that follows. ARR is a financial measure that we define as the annualized value of all recurring revenue contracts active at the end of a reporting period. ARR includes the annualized value of subscriptions and the annualized value software support contracts related to perpetual licenses active at the end of a reporting period and does not include revenue reported as perpetual license or professional services in our consolidated statement of operations. ARR should be viewed independently of revenue, unearned revenue, and customer arrangements with termination rights as ARR is an operating metric and is not intended to be combined with or replace these items. ARR is not a forecast of future revenue and can be impacted by contract start and end dates and renewal rates.

Conference Call and Webcast

MobileIron will report final results for the fourth quarter and fiscal year 2018 on Thursday, February 7, 2019 after the close of the market and host a conference call and live webcast at 1:30 p.m. Pacific Time (4:30 p.m. ET) to discuss the company's financial results and business highlights. Interested parties may access the call by dialing 1-866-602-7050 in the U.S. or 1-409-216-6455 from international locations (passcode 9796668). The live webcast will be

Non-GAAP Financial Measures and Reconciliations

To supplement our financial results presented on a U.S. GAAP basis, we provide investors with certain non-GAAP financial measures, including billings, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss), non-GAAP operating margin, non-GAAP net income (loss), non-GAAP net income (loss) per share and free cash flow. These non-GAAP financial measures exclude stock-based compensation, amortization of intangible assets, a litigation settlement charge, and restructuring charges.

Stock-based compensation expenses: In our non-GAAP financial measures, we have excluded the effect of stock-based compensation expenses. We exclude stock-based compensation expense because it is non-cash in nature and excluding this expense provides meaningful supplemental information regarding our operational performance. In particular, because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FASB ASC Topic 718, we believe that providing non-GAAP financial measures that exclude this expense allows investors the ability to make more meaningful comparisons between MobileIron operating results and those of other companies. Stock-based compensation expenses will recur in future periods.

Amortization of intangible assets: In our non-GAAP financial measures, we have excluded the effect of the amortization of intangible assets. Amortization of intangible assets can be significantly affected by the timing and size of our acquisitions. Beginning our second quarter ended June 30, 2018, we no longer have amortizing intangible assets.

Litigation settlement charges: In our non-GAAP financial measures, we have excluded the charge for the cost of the settlement of our shareholder litigation. While it is possible that we will have material litigation-related charges in the future, we do not expect it to be a consistently recurring expense.

Restructuring charges: In our non-GAAP financial measures, we have excluded the effect of severance and other expenses related to a reduction in our workforce. Restructuring charges may recur in the future; however, the timing and amounts are difficult to predict.

Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating loss, non-GAAP operating margin, non-GAAP net loss, and non-GAAP net loss per share: We believe that the exclusion of stock-based compensation expense, the amortization of intangible assets, the litigation settlement charge, and restructuring charges from various non-GAAP financial metrics such as gross profit, gross margin, operating income (loss), operating margin, net income (loss), and net income (loss) per share provides useful measures for management and investors. Stock-based compensation, restructuring charges, and the amortization of intangible assets have been and can continue to be inconsistent in amount from period to period. Other than in 2017, we have not historically had a material litigation-related settlement charge. While it is possible that we will have material litigation settlement charges in the future, we do not expect it to be a consistently recurring expense. We believe the inclusion of these items makes it difficult to compare periods and understand the growth and performance of our business. In addition, we evaluate our business performance and compensate management based in part on these non-GAAP measures. There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by our competitors and exclude expenses that may have a material impact on our reported financial results. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in our business and an important part of the compensation provided to our employees.
