Significant Accounting Policies Segment Reporting. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. Our chief operating decision-maker reviews financial information presented on a consolidated basis. Accordingly, we consider ourselves to be in a single reporting segment, specifically the discovery, development and commercialization of visual prosthetics for profoundly blind individuals. We historically managed our Argus II and Orion programs on a consolidated basis within this single operating segment and do not assess the performance of our product lines or geographic regions on other measures of income or expense, such as program expense, operating income or net income. Our underlying technology consists of hardware components (implanted and wearable) and software. A vast majority of this underlying technology is shared between our Argus II and Orion branded systems. While we have ceased marketing the Argus II product indicated for individuals with retinitis pigmentosa, we are developing Orion as a next generation product with potential to treat a broader market of blind individuals, including the retinitis pigmentosa market. Based upon our decision on May 10, 2019 to accelerate our transition to the Orion platform and suspend production of Argus, we recorded impairment charges of $2.6 million related to inventory of Argus II in the six months ended June 30, 2019. As part of this transition we commenced a corporate restructuring plan to focus on development of Orion and other key research projects. On March 31, 2020, due to the COVID-19 pandemic and related inability to secure additional funding, we laid off the majority of our employees and reduced our operating expenses significantly to allow for our continuing business operations. Due to our focus on Orion and wind down of selling and marketing activities related to Argus II, we recorded further impairment charges to our inventory of $0.5 million and $0.7 million to our fixed assets used primarily for Argus activities. We also incurred $1.0 million in severance payments and other costs associated with the wind down, all of which were substantially paid by June 30, 2020. We continue to advance the development of our Orion technology and are exploring various strategic options, however we cannot assure that any of these endeavors will yield satisfactory results or that we will be able to maintain our operations. Our significant accounting policies are set forth in Note 2 of the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2019. Recently Issued Accounting Pronouncements We do not believe that any recently issued, but not yet effective, accounting standards, if adopted, will have a material effect on the financial statements.
