Key Operating Metrics
Core revenue excludes revenue attributable to the products from two small legacy acquisitions, both of which occurred prior to 2008, which we do not consider to be a core part of our strategic focus going forward.
Number of core customers includes all customers who subscribe to at least one of our solutions other than the non-core, legacy products.
Average revenue per core customer is total core revenue divided by the average monthly number of core customers during the period.Subscription dollar retention rate is calculated for a particular period by establishing the cohort of core customers that had active contracts as of the end of the prior period. We then calculate our subscription dollar retention rate by taking the amount of fixed subscription revenue we recognized for the cohort in the period for which we are reporting the rate and dividing it by the fixed subscription revenue we recognized for the same cohort in the prior period. For this purpose, we do not include any non-core revenue, any variable subscription fees paid by our customers or any implementation fees. Non-GAAP Financial Measures This press release contains the following non-GAAP financial measures: core revenue, non-GAAP net loss, non-GAAP net loss per share and adjusted EBITDA. ChannelAdvisor believes that these non-GAAP measures of financial results provide useful information to management and investors relating to ChannelAdvisor’s financial condition and results of operations. The company’s management uses these non-GAAP measures to compare the company’s performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company’s financial measures with other software companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making.
