Components of Results of Operations
Revenue
We expect to continue to derive substantially all our revenue from sales of our Platform, which includes sales of our Instrument, test strips, other related products and services and our Fast Lab Solution. Such sales may have multiple performance obligations under IFRS 15 Revenue from Contracts with Customers, or IFRS 15; therefore, we may recognize revenue associated with a single sale of our Platform both at a point in time and over time. We recognize revenue from the initial sale of the Instrument, test strips and other related products separate from the sale of our connectivity solutions and other services under IFRS 15.
Our Platform will also be made available to customers under operating lease arrangements. Revenue from operating leases are recognized on a straight-line basis over the term or, when lease revenue is entirely variable and subject to subsequent reagent sales, as the performance obligation to deliver reagents is satisfied.
We allocate revenue between products and services based on the relative standalone selling price of each performance obligation.
Products. We derive a significant portion of our product revenue from the sale of our Instrument, test strips, other related products and our Fast Lab Solution. We sell or lease our products directly to users, including healthcare systems, government organizations, national pharmacy chains, diagnostic labs, hospitals and other healthcare providers. In addition, we sell the Instrument, test strips and other related products through wholesalers and distributors. We sell, place free of charge and rent Instruments to customers depending on the needs of the customer and market profile.
Services. We expect to derive substantially all our service revenue from revenue allocated from the sale of our Platform to our connectivity solutions, such as Connect Manager and EHR Connect. These services allow customers to manage their Instruments and to analyze diagnostic data, provide decision support tools and enforce quality control policies. During 2021 and 2022, less than 1% of our service revenue was derived from sales of our Platform. During this time, the majority of our service revenue related to maintenance on historical software licenses, access to hosted cloud offerings, training, support and other services related to products.
We intend to seek, in the near term, regulatory approval, authorization, certification or clearance for multiple diagnostic assays on our Platform. Assuming we receive regulatory approvals, authorizations, certifications or clearances, we expect the revenue from sales of our Instrument, test strips and other related products and services to increase significantly.
Costs of Sales and Operating Expenses
Cost of sales. Cost of sales generally consists of the cost of (i) materials and direct labor, including bonus and benefits, (ii) equipment and infrastructure expenses associated with manufacturing and packaging our Platform products, (iii) third party products, (iv) warehousing, handling and shipping costs and (v) the provision of software support and services. Equipment and infrastructure expenses include maintenance and depreciation of manufacturing equipment, facilities costs and amortization of leasehold improvements and of acquired technology. Also included are provisions for excess and obsolete inventory and warranty returns. As we continue to scale our manufacturing operations, improve existing products and introduce new products, it is possible that we will have obsolete parts and materials and our manufacturing output will not match demand, especially in times of volatile demand resulting in write downs for obsolete and short expiry materials and products. 1
We expect cost of sales to generally increase in line with the increase in the number of Platform products we sell.
Research and development expense. Research and development expense consists of costs incurred to develop our Platform, and includes salaries and benefits, equipment and supplies used in research and development laboratory work, infrastructure expenses, including allocated facility occupancy and information technology costs, contract services, clinical trials and other outside costs, and costs to develop our technology and add additional assays to our Platform. Research and development costs are expensed as incurred.
We expect that our research and development expenses will continue to increase as we continue to develop additional assays for our Platform and conduct our ongoing and new clinical trials. These expenses may fluctuate from period to period due to the timing and extent of these expenses incurred within a period.
