We define adjusted EBITDA to also exclude restructuring costs, although we have not incurred any such costs to date. ● We define “free cash flow” as net cash provided by operating activities less purchases of property and equipment (net of proceeds from disposals). ● We define “adjusted operating income (loss)” as our income (loss) from operations excluding stock-based compensation.

Gross Margin We generally expect gross margin to range between 40% and 45% for the foreseeable future, with direct manufacturing costs approximating 50% to 55% of revenue and overhead costs totaling approximately 5% of revenue. We seek to maintain our gross margin by continuing to develop proprietary technologies that avoid pricing pressure for our wet cleaning equipment.

Consistent with our methodology for calculating adjusted EBITDA, we do not adjust free cash flow for the effects of PRC government subsidies, because we take those subsidies into account in incurring expenses and capital expenditures. We do not adjust free cash flow for the effects of time-deposits, which for our internal purposes are considered as largely similar to cash.
