To supplement our financial results, which are prepared and presented in accordance with GAAP, we use certain Non-GAAP financial measures, as described below, to understand and evaluate our core performance. These Non-GAAP measures, which may be different than similarly-titled measures used by other companies, are presented to enhance investors’ overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We define "Non-GAAP Gross Profit and Non-GAAP Gross Margin" as GAAP gross profit and GAAP gross margin, adjusted for stock-based compensation expense included in cost of revenue. We define “Non-GAAP Loss from Operations” as our income (loss) from operations adjusted to exclude stock-based compensation, acquisition costs and amortization of acquired intangible assets. We define “Non-GAAP Net Loss” as our net income (loss) adjusted to exclude stock-based compensation, acquisition costs, amortization of acquired intangible assets and gain on extinguishment of debt.

We define “Non-GAAP EPS”, as our Non-GAAP Net Income (Loss) divided by our GAAP weighted-average number of shares outstanding for the period on a diluted basis. Management uses Non-GAAP EPS to evaluate the performance of our business on a comparable basis from period to period.

The above items are excluded from our Non-GAAP Gross Profit, Non-GAAP Income (Loss) from Operations and Non-GAAP Net Income (Loss) because these items are non-cash in nature, or are not indicative of our core operating performance, and render comparisons with prior periods and competitors less meaningful. We believe Non-GAAP Gross Profit, Non-GAAP Income (Loss) from Operations and Non-GAAP Net Income (Loss) provide useful supplemental information to investors and others in understanding and evaluating our results of operations, as well as provide a useful measure for period-to-period comparisons of our business performance.

We define free cash flow as net cash (used in) provided by operating activities less cash used for purchases of property and equipment. We believe that free cash flow is a useful indicator of liquidity that provides information to management and investors, even if negative, about the amount of cash used in our operations other than that used for investments in property and equipment.

Other Business Metrics

Annual Contract Value (ACV) – we define Annual Contract Value for an individual customer agreement as the total fixed fees under the agreement divided by the number of years in the agreement term. Our total ACV is the aggregate ACVs for all our customers as measured at a given point in time. Total fixed fees includes licensing, support and maintenance and other fixed fees under IP licensing or software licensing agreements but excludes variable revenue derived from licensing agreements with customers, particularly royalties. We monitor ACV to measure our success and believe the increase in the number shows our progress in expanding our customers’ adoption of our solutions. ACV fluctuates due to a number of factors, including the timing, duration and dollar amount of customer contracts.

Active Customers – we define Active Customers as customers who have entered into a license agreement with us that remains in effect. The retention and expansion of our relationships with existing customers are key indicators of our revenue potential.

Confirmed Design Starts – we define Confirmed Design Starts as when customers confirm their commencement of new semiconductor designs using our interconnect IP and notify us. Confirmed Design Starts is a metric management uses to assess the activity level of our customers in terms of the number of new semiconductor designs that are started using our interconnect IP in a given period. We believe that the number of Confirmed Design Starts is an important indicator of the growth of our business and future royalty revenue trends.

Remaining Performance Obligations (RPO) – we define Remaining Performance Obligations as the amount of contracted future revenue that has not yet been recognized, including both deferred revenue and contracted amounts that will be invoiced and recognized as revenue in future periods.
