Impact of Coronavirus (COVID-19) [Text Block]	3. Impact of Coronavirus (COVID-19) While the coronavirus pandemic (“pandemic”) continues to impact certain areas of the Company’s operations, the current impact on the Company’s financial performance is coming primarily from higher raw material costs and increased shipping costs, which had an impact on the Company’s gross profit margins in the second quarter of 2022 and may continue to have a future impact on the Company’s gross profit margins in upcoming quarters. In addition, during the first half of 2022 it was more difficult to ship the Company’s products due to a shortage of truck drivers and limited availability of shipping vessels. This situation began to gradually improve during the second quarter of 2022. The shortage of truck drivers and shipping vessels is expected to continue to improve as the year progresses, but this will be at least partially contingent upon the extent to which the impact of the pandemic lessens globally. The Company has been able to minimize the impact on customers by making them aware of longer lead times that may be necessary as a result of these issues. The pandemic has not significantly affected the ability of the Company to obtain raw materials, but has created longer lead times for some of them. In response to the rising raw material prices the Company has instituted price increases on many of its products, which will help to reduce the impact on the Company’s gross margins in the future. As a result of the lingering effects of the coronavirus pandemic as described above, there continues to be uncertainty in regard to the future potential impact of the pandemic on the Company’s operations or financial results. The Company believes that it is still unable to provide an accurate estimate or projection as to what the future impact of the pandemic will be on the Company’s future operations or financial results. The Company does not expect the carrying value of its assets or its liquidity to be impaired by the coronavirus pandemic.
