COVID-19	4. COVID-19 The impact of the COVID-19 pandemic on our future consolidated results of operations remains uncertain. The extent to which COVID-19 impacts our employees, operations, customers, suppliers and financial results depends on numerous evolving factors that we may not be able to accurately predict, including: the duration and scope of the pandemic (and whether there is a resurgence or multiple resurgences in the future, including the impact of new variants); government actions taken in response to the pandemic, including required shutdowns or vaccine or testing mandates; the availability, acceptance, distribution and continued effectiveness of vaccines; the impact on construction activity, including the effect on our customers’ demand for our ceiling and wall systems; supply chain disruptions; rising inflation; labor shortages; sustained remote or hybrid work models; our ability to manufacture and sell our products; and the ability of our customers to pay for our products. While many of our products support life-sustaining activities and essential construction, we and certain of our customers or suppliers may be impacted by national, federal, state and provincial actions, orders and policies regarding the COVID-19 pandemic, including: temporary closures of non-life-sustaining businesses, shelter-in-place orders, and travel, social distancing and quarantine policies, the implementation and enforcement of which vary in each of the jurisdictions in which we operate. We did not record any asset impairments, inventory charges or material bad debt reserves related to COVID-19 during the three and nine months ended September 30, 2022 and 2021, but future events may require such charges which could have a material adverse effect on our financial condition, liquidity or results of operations. Government subsidies In the United States, the Employee Retention Credit ("ERC") was established by Section 2301 of the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") to provide an incentive for employers to keep their employees on their payroll during COVID-19 closures. The ERC is a refundable payroll tax credit based on qualified wages paid by an eligible employer between March 12, 2020, and October 1, 2021 for companies experiencing a significant decline in gross receipts during a calendar quarter or having operations fully or partially suspended during the quarter due to COVID-19. During the third quarter of 2022, the Company determined it was eligible for the ERC for the first three quarters of 2021 and has filed a claim for $7.3 million in payroll tax credits ($7.1 million net of expenses). As of September 30, 2022 these credits have not been received and are included in other receivables in the balance sheet. As part of the Canadian federal government’s COVID-19 Economic Response Plan, the Canadian government established the Canadian Emergency Wage Subsidy (“CEWS”). The CEWS provided the Company with a taxable subsidy in respect of a specific portion of wages paid to Canadian employees during qualifying periods extending from March 15, 2020 to October 23, 2021 based on the percentage decline of certain of the Company’s Canadian sourced revenues during each qualifying period. The Company’s eligibility for the CEWS was subject to change for each qualifying period and was reviewed by the Company for each qualifying period, with amounts being received by the Company for various, but not each, qualifying period. Pursuant to amendments enacted as part of the 2021 Canadian federal budget, the Company is required to repay a portion of the CEWS amounts received for any qualifying period commencing after June 5, 2021 where the aggregate compensation for “specified executives” (within the meaning of the CEWS) during the 2021 calendar year exceeds the aggregate compensation for “specified executives” during the 2019 calendar year. Upon finalization of 2021 compensation to specified executives, approximately C$0.5 million ($0.4 million) of subsidies was repaid to the Canadian authorities in the second quarter of 2022. The repayment amount was fully provided for in the third quarter of 2021 in accounts payable and accrued liabilities and in the first quarter of 2022 the Company reversed a $0.6 million incremental provision related to this that is no longer necessary. On November 19, 2020, the Canadian government also implemented the Canada Emergency Rent Subsidy (“CERS”). The CERS provided a taxable subsidy to cover eligible expenses for qualifying properties, subject to certain maximums, for qualifying periods extending from September 27, 2020 to October 23, 2021, with the amount of the subsidy available to the Company being based on the percentage decline of certain of the Company’s Canadian-sourced revenues in each qualifying period. The Company’s eligibility for the CERS was subject to change for each qualifying period and was reviewed by the Company for each qualifying period. The last claim period under the CEWS and CERS programs ended on October 23, 2021. The Company is not eligible and did not receive any new Canadian government subsidies in the three or nine months ended September 30, 2022.
