Different assumptions from those made in our analysis could materially affect projected cash flows and the evaluation of assets for impairment.
Key assumptions include, but are not limited to, revenue projections, revenue growth rates, discount rates and other factors. We consider peer revenues and earnings trading multiples from companies that have operational and financial characteristics that are similar to the asset under measurement and estimated weighted-average costs of capital.
Installation services are considered distinct from the instrument. Therefore, instrument revenue is recognized upon transfer of control of the asset to the customer, which is generally upon delivery for sales made to our non-distributor customers and upon shipment for sales made to our distributor customers.

The decrease in gross margin percentage was primarily due to adjustments for excess inventory, either on hand or at our contract manufacturer, r elated to a faster than expected ramp in Revio demand, which resulted in a faster than expected decline in Sequel II/IIe demand upon the launch of Revio , as well as a decrease in instrument sales volume and higher product costs, which was partially offset by consumables volumes and higher service and other revenues during the year ended December 31, 2022, compared to the year ended December 31, 2021.
The decrease in gross margin percentage was primarily due to instrument mix, in addition to charges for scrap inventory and an increase in adjustments primarily relating to excess consumables inventory resulting from a faster-than-expected decline in demand of Sequel II/IIe consumables due primarily to a faster than expected ramp on the Revio system.
The increase in consumable sales was primarily due to higher Sequel II/IIe consumables sales attributable to the growth in the instrument installed base. Consumable growth reflects approximately 24% growth in Sequel II and IIe SMRT cells shipped in 2022, as compared to 2021.
The increase in consumable sales was primarily due to higher Revio consumables sales attributable to the growth in the Revio instrument installed base, partially offset by a decline in Sequel consumables as customers transition to the new platform.
