​ We evaluate inventory for obsolescence on at least a quarterly basis or more frequently if needed. Our HPP segment has a multi-faceted approach in determining obsolescence including reviewing inventory by product line, program, and individual part. In the TS segment, we seek to minimize obsolete inventory by having nearly all of our inventory purchased in conjunction with a sales agreement. From time to time, we do purchase certain inventory in bulk to receive discounts, but only when we anticipate selling this inventory. The inventory we purchase at the TS segment is in high demand, especially in the current environment, and has a limited risk of obsolescence. ​ Several components used in our HPP segment products are obtained from sole-source suppliers. We are dependent on key vendors such as ADP, NXP, and BCRM for a variety of processors for certain products. We are dependent on NVIDIA for our high-speed interconnect components and Marvel for Myricom components. Despite our dependence on these sole-source suppliers, based on our current forecast and our projected sales obligations, we believe we have adequate inventory on hand and our current near-term requirements can be met in the existing supply chain. COVID-19 has adversely affected the distribution channel leading to significantly longer lead times when ordering product. Manufacturers are not producing as much product as prior to the pandemic due to disruptions, resulting in supply shortages. Additionally, recent global shipping delays have exacerbated this problem. The TS segment has many vendors it transacts with and supply shortages are pervasive with many of them. ​
