In addition, the revolving credit facility is subject to an undrawn commitment fee ranging between 0.15% and 0.25% based on the Total Leverage Ratio (as defined in the Senior Credit Agreement) and the daily average undrawn balance. The Senior Credit Agreement terminates on January 23, 2024.
Borrowings under the Senior Credit Agreement are secured by the trade receivables, inventory, personal property, equipment, and general intangibles of the Company’s significant domestic subsidiaries. Capital distributions under the Senior Credit Agreement are capped at an annual aggregate limit of $75 million if the Company's leverage ratio is over 3.0 times.

Equity Based Awards - Settled in Stock
The following table sets forth the number of equity-based awards granted during the three months ended March 31, which will convert to shares upon vesting, along with the weighted average grant date fair values:

| 2022 |  | 2021
Awards | Number of Awards |  | Weighted Average Grant Date Fair Value |  | Number of Awards (2) |  | Weighted Average Grant Date Fair Value
Performance stock units (1) | 108,464 |  |  | $ | 47.00 |  |  | 62,778 |  |  | $ | 87.84 |
Restricted stock units | 58,958 |  |  | $ | 47.00 |  |  | 33,187 |  |  | $ | 87.91 |

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance or market conditions. The number of shares to be issued may vary between 0% and 200% of the number of PSUs granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on either the Company’s return on invested capital (“ROIC”) over a one-year performance period. The Company's PSUs with a market condition are based on the ranking of the Company’s total stockholder return (“TSR”) performance, on a percentile basis, over a three year performance period compared to the S&P Small Cap Industrial sector, over the same three year performance period.
(2) All PSUs granted in the first quarter of 2021 were forfeited in the first quarter of 2022 as the threshold level of achievement was not met based on the Company's actual ROIC achievement level for the performance period ended December 31, 2021.
Equity Based Awards - Settled in Cash
The Company's equity-based awards that are settled in cash are the awards under the Management Stock Purchase Plan (the "MSPP") which is authorized under the Company's equity incentive plans. The total of these share-based liabilities recorded on the consolidated balance sheet as of March 31, 2022 was $18.9 million, of which $2.0 million was included in current accrued expenses and $16.9 million was included in non-current liabilities. Total share-based liabilities as of December 31, 2021 were $22.6 million, of which $2.9 million was included in current accrued expenses and $19.7 million was included in non-current liabilities.
The Company's MSPP provides participants the ability to defer a portion of their compensation, convertible to unrestricted investments, restricted stock units, or a combination of both, or defer a portion of their directors’ fees, convertible to restricted stock units. Employees eligible to defer a portion of their compensation also receive a company-matching award in restricted stock units equal to a percentage of their compensation.
The deferrals and related company match are credited to an account that represents a share-based liability. The portion of the account deferred to unrestricted investments is measured at fair market value of the unrestricted investments, and the portion of the account deferred to restricted stock units and company-matching restricted stock units is measured at a 200-day average of the Company’s stock price. The account will be converted to and settled in cash payable to participants upon retirement or a termination of their service to the Company.
The following table provides the number of restricted stock units credited to active participant accounts and the payments made with respect to restricted stock units issued under the MSPP during the three months ended March 31,:

| 2022 |  | 2021
Restricted stock units credited | 2,876 |  |  | 24,085 |
Share-based liabilities paid (in thousands) | $ | 2,545 |  |  | $ | 3,510 |

(10) HELD FOR SALE AND DISCONTINUED OPERATIONS
Held for Sale
During the first quarter of 2022, the Company committed to a plan to sell its Processing business (the "disposal group") which is a business within the Company's Agtech reportable segment. The planned sale does not meet the criteria to be classified as a discontinued operation. As a result, the Company will continue reporting the operating results of the disposal group in the Company's consolidated operating results from continuing operations until the sale of the business is completed.
The Company classifies assets and related liabilities as held for sale when: (i) management has committed to a plan to sell the assets, (ii) the net assets are available for immediate sale, (iii) there is an active program to locate a buyer and (iv) the sale and transfer of the net assets is probable within one year. Assets and liabilities held for sale are presented separately on our consolidated balance sheets with a valuation allowance, if necessary, to recognize the net carrying amount at the lower of cost or fair value, less costs to sell.
As of March 31, 2022, the assets and liabilities of the disposal group have been classified as held for sale. The following table summarizes these assets and liabilities which have been measured at the lower of (i) the carrying value when classified as held for sale and (ii) the fair value of the business less costs to sell.

(in thousands) |  | March 31, 2022
Assets held for sale |  |
Accounts receivable, net of allowance |  | $ | 1,260 |
Inventories, net of reserves |  | 8,093 |
Other current assets |  | 1,627 |
Property, plant, and equipment, net |  | 331 |
Operating lease asset |  | 415 |
Goodwill (1) |  | — |
Acquired intangibles, net |  | 6,213 |
Total assets held for sale |  | $ | 17,939 |
Liabilities held for sale |  |
Accounts payable |  | $ | 1,291 |
Accrued expenses |  | 1,172 |
Non-current operating lease liabilities |  | 172 |
Total liabilities held for sale |  | $ | 2,635 |

(1) The assignment of goodwill was based on the relative fair value of the disposal group compared to the fair value of the total reporting unit it was included in prior to being reclassified as held for sale.
Net sales and operating loss for held for sale operations for the three months ended March 31 are as follows (in thousands):

| 2022 | 2021
Net sales | $ | 1,823 |  | $ | 4,973 |
Operating loss | $ | (2,525) |  | $ | (749) |

Effective with the classification of the disposal group as held for sale, depreciation of property, plant and equipment and amortization of finite-lived intangible assets and right-of-use assets are not recorded while these assets are classified as held for sale. As a result of our evaluation of the recoverability of the carrying value of the assets and liabilities held for sale relative to an estimated sales price, adjusted for costs to sell, no losses were recorded during the three months ended March 31, 2022. The recoverability of the disposal group will be evaluated each reporting period until the sale of the business is completed.

Discontinued Operations
On February 23, 2021, the Company sold the stock of its Industrial business which had been classified as held for sale and reported as a discontinued operation in the Company’s consolidated financial statements for the year ended December 31, 2021. Net proceeds of $38 million, consisting of cash and a $13 million seller note, resulted in an estimated pre-tax loss of $30 million, subject to working capital and other adjustments, of which $29.6 million was recorded when the assets of the Industrial business were written down to fair market value during the fourth quarter of 2020. The seller note was paid in full to the Company during the second quarter of 2021.
The results of operations and financial position of the Industrial business have been presented as a discontinued operation in the Company's consolidated financial statements for all periods presented. The Company allocates interest to its discontinued operations in accordance with ASC Subtopic 205-20, “Presentation of Financial Statements – Discontinued Operations.” Interest was allocated based on the amount of net assets held by the discontinued operation in comparison to consolidated net assets.

(11) EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS
The Company has incurred exit activity costs and asset impairment charges as a result of its 80/20 simplification and portfolio management initiatives. These initiatives have resulted in the identification of low-volume, low margin, internally-produced products which have been or will be outsourced or discontinued, the simplification of processes, the sale and exiting of less profitable businesses or product lines, and a reduction in our manufacturing footprint.
Exit activity costs (recoveries) were incurred during the three months ended March 31, 2022 and 2021 which related to moving and closing costs, severance, and contract terminations, along with asset impairment charges related to the write-down of inventory and impairment of machinery and equipment associated with discontinued product lines, as a result of process simplification initiatives. In conjunction with these initiatives, the Company closed one facility during the three months ended March 31, 2022. During the three months ended March 31, 2021, the Company closed two facilities as a result of these initiatives.

COVID Update and Recent Trends
Our top priority continues to be focused on our organization - keeping our team and their families as safe as possible, maintaining our supply chain and providing a high level of responsiveness to customer needs. We continue to proactively execute our pandemic “playbook” and make adjustments to our operating protocols as we navigate forward.
COVID-19, as well as broader market dynamics over the past two years, have resulted in impacts to our company, including increased material cost inflation, labor availability issues and logistics costs increases. We have also been impacted from supply constraints for materials and commodities used in our operations. In certain instances these constraints have resulted in project delays, cost inflation and logistics delays. We continue to work with our customers and suppliers in this dynamic environment to better align pricing, understand the existing and potential future impacts to our supply chain, and make efforts to mitigate such impacts as we expect these supply chain and labor availability pressures along with the impact of material cost, labor and logistics inflation will continue throughout 2022.
In early 2022, the U.S. Department of Commerce ("USDOC") was petitioned to investigate alleged circumvention of antidumping and countervailing duties on Chinese imports of solar panels produced in other countries in Southeast Asia. In March 2022, the USDOC announced that it would investigate the circumvention alleged in the petition. As the timing and progress of many of our customers’ projects depend upon the supply of solar panels, our operating results could be impacted. As such, we are working closely with customers to assess any potential exposure to the USDOC’s solar panel anti-circumvention investigation.

Recent Developments
In May 2022, the Company's Board of Directors authorized a share repurchase program of up to $200 million of the Company's issued and outstanding common stock. The program has a duration of three years, ending May 2, 2025. Repurchases may be made, from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions, applicable legal requirements, debt covenants and other considerations. Any such repurchases may be executed using open market purchases, privately negotiated agreements or other transactions. The repurchase program may be suspended or discontinued at any time at the Company's discretion. The Company has not made repurchases under the repurchase program to date.
During the first quarter of 2022, the Company committed to a plan to sell its processing equipment business, which is a business within the Company's Agtech reportable segment, as a result of its portfolio management strategy in order to focus its resources on the higher growth and more profitable growing business within the Agtech segment. The processing equipment business has been classified as held for sale as of March 31, 2022.
During the first quarter of 2021, the Company sold its Industrial business which was previously included in the Company's Industrial and Infrastructure Products segment, now the Infrastructure segment and was reported as discontinued operations as of December 31, 2020.

Consolidated net sales increased by $30.3 million, or 10.5%, to $317.9 million for the three months ended March 31, 2022 compared to the three months ended March 31, 2021. The 10.5% increase in revenue was driven by the Residential and Infrastructure segments, which more than offset volume declines in both our Renewables and Agtech segments. The improvement year over year was driven by a 15% increase in pricing to customers, partially offset by a net volume decline of 5%. The increase during the current year quarter was driven by participation gains and price in our Residential segment, partially offset by continued supply chain challenges in the Renewables segment. While the Company committed to a plan of sale of its Processing business within the Agtech segment, and has reclassified the assets and liabilities as held-for-sale on the March 31, 2022 balance sheet, the Company will continue reporting its operating results in the Company's consolidated operating results from continuing operations until the sale of the business is completed. Consolidated backlog increased 23% to $437 million up from $355 million at the end of the prior year quarter.
Net sales in our Renewables segment decreased $6.7 million, or 7.8%, to $78.8 million for the three months ended March 31, 2022 compared to $85.5 million for the three months ended March 31, 2021. Revenue decreased as anticipated by 7.8% during the quarter as a result of solar project schedule delays and disruptions related to supply chain challenges as well as impacts from severe winter weather early in the quarter. Backlog improved 41% year over year, driven by continued end market demand for this segment.
Net sales in our Residential segment increased 28.0%, or $39.3 million, to $179.5 million for the three months ended March 31, 2022 compared to $140.2 million for the three months ended March 31, 2021. The increase from the prior year quarter, the seventh consecutive quarter of double-digit growth, was driven by market demand, additional price actions, and participation gains, particularly in the building products and mail and package businesses.
Net sales in our Agtech segment decreased 9.2%, or $4.3 million, to $42.4 million for the three months ended March 31, 2022 compared to $46.7 million for the three months ended March 31, 2021. Excluding the impact of the processing equipment business which has been classified as held for sale as of March 31, 2022, revenue declined in our produce and cannabis businesses due to continued licensing and permit delays, and scheduled timing of projects. Despite these headwinds, the commercial greenhouse business continued solid growth across its core product lines serving the retail, institutional and car wash markets. Backlog increased 17% year over year..
Net sales in our Infrastructure segment increased 13.9%, or $2.0 million, to $17.2 million for the three months ended March 31, 2022 compared to $15.1 million for the three months ended March 31, 2021. The increase in revenue was driven by growth in demand for fabricated products. While order backlog declined 7% as compared to the prior year quarter, on timing of orders and revenues, the segment's pipeline and bidding activity remain strong. Management continues to expect the impact of incremental government spending on infrastructure toward the end of 2022.
Our consolidated gross margin decreased to 20.4% for the three months ended March 31, 2022 compared to 20.9% for the three months ended March 31, 2021. The decrease was largely the result of continued and anticipated supply chain disruptions, materials cost inflation along with labor availability, and severe winter weather related inefficiencies in several of our businesses. Largely offsetting these impacts were improved operating execution from lean enterprise initiatives, supply chain optimization activities, favorable revenue mix and the impact of participation gains in several of our other businesses.

Selling, general, and administrative ("SG&A") expenses decreased by $3.6 million, or 7.5%, to $43.6 million for the three months ended March 31, 2022 from $47.2 million for the three months ended March 31, 2021. The decrease year over year was largely due to lower performance-based compensation expense for equity-based awards tied to the Company's 200-day average stock price which declined as compared to the prior year quarter. SG&A expenses as a percentage of net sales decreased to 13.7% for the three months ended March 31, 2022 compared to 16.4% for the three months ended March 31, 2021.
The following table sets forth the Company’s income from operations and income from operations as a percentage of net sales by reportable segment for the three months ended March 31, (in thousands):

Income from operations: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Renewables | $ | (6,984) |  |  | (8.9) | % |  | $ | (521) |  |  | (0.6) | % |  | $ | (6,463) |  |  |  |  |  |  | $ | — |  |  | $ | (6,463) |

Unallocated Corporate Expenses | (6,468) |  |  | (2.0) | % |  | (12,564) |  |  | (4.4) | % |  | 6,096 |  |  |  |  |  |  | — |  |  | 6,096 |

The Renewables segment generated an operating margin of (8.9)% in the current year quarter compared to (0.6)% in the prior year quarter. The decrease in operating margin on lower volume was the result of project management inefficiencies related to project delays and disruptions associated with market supply chain disruptions and an unanticipated level of inflation on structural steel used in solar canopy projects that carried over from the end of the prior year into the first two months of the current year quarter. Furthermore, severe winter weather resulted in project inefficiencies during the quarter. We continue executing our integration plans which remain on track.
The Residential segment generated an operating margin of 18.6% in the current year quarter compared to 16.4% in the prior year quarter. The increase in operating margin was the result of favorable price / cost management, segment mix, and 80/20 initiatives.
Our Agtech segment generated an operating margin of 0.1% in the current year quarter compared to 2.0% in the prior year quarter. Excluding the impact of the Processing business which has been classified as held for sale as of March 31, 2022, operating profit and margin improved year over year, the result of continued execution from 80/20 and lean enterprise initiatives, ongoing integration activities, improved business mix, and supply chain optimization projects.
Our Infrastructure segment generated an operating margin of 6.9% during the three months ended March 31, 2022 compared to 13.5% during the three months ended March 31, 2021. The margin declined year over year as plate steel inflation impacted fixed price projects and the fabrication business experienced labor availability and inefficiencies related to adding second shift capacity to support increased demand.
Unallocated corporate expenses decreased $6.1 million from $12.6 million during the three months ended March 31, 2021 to $6.5 million during the three months ended March 31, 2022. The decrease in expense was primarily the result of lower performance-based compensation expense for equity-based awards tied to the Company's 200-day average stock price which declined as compared to the prior year quarter.
Interest expense increased slightly year over year with $0.5 million for the three months ended March 31, 2022 compared to $0.4 million for the three months ended March 31, 2021. The outstanding balances on the Company's revolving credit facility were $42.4 million and $58.0 million as of March 31, 2022, and 2021, respectively.
We recognized a provision for income taxes of $5.1 million and $1.6 million, with effective tax rates of 24.8% and 12.9% for the three months ended March 31, 2022, and 2021, respectively. The effective tax rate for the three months ended March 31, 2022 was greater than the U.S. federal statutory rate of 21% due to state taxes and

nondeductible permanent differences partially offset by favorable discrete items due to an excess tax benefit on stock-based compensation. The effective tax rate for the three months ended March 31, 2021 was less than the U.S. federal statutory rate of 21% due to favorable discrete items due to an excess tax benefit on stock-based compensation, partially offset by state taxes and nondeductible permanent differences.
Liquidity and Capital Resources
The following table sets forth our liquidity position as of:

(in thousands) |  | March 31, 2022 |  | December 31, 2021
Cash and cash equivalents |  | $ | 15,573 |  |  | $ | 12,849 |
Availability on revolving credit facility |  | 351,505 |  |  | 369,305 |
|  | $ | 367,078 |  |  | $ | 382,154 |

Sources of Liquidity
We believe that our cash on hand and available borrowing capacity provided under our Sixth Amended and Restated Credit Agreement (the "Senior Credit Agreement") provide us with ample liquidity and capital resources to invest in key business strategies that drive our mission. We have been able to weather the economic impacts of the COVID-19 pandemic and the broader market dynamics, including the current inflationary cost environment, while continuing to make investments that support our strategy. We continue to remain focused on managing our working capital, closely monitoring customer credit and collection activities, and working to extend payment terms. We believe our liquidity, together with the cash expected to be generated from operations, should be sufficient to fund working capital needs and stock repurchases and to invest in operational excellence and growth initiatives for the foreseeable future.
Our Senior Credit Agreement provides us with liquidity and capital resources for use by our U.S. operations. Historically, our foreign operations have generated cash flow from operations sufficient to invest in working capital and fund their capital improvements. As of March 31, 2022, our foreign subsidiaries held $13.0 million of cash.
Outstanding balances on our revolving credit facility under our Senior Credit Agreement accrue interest at a rate based on LIBOR plus an additional margin. We do not expect a material change in interest expense as a result of transitioning from a LIBOR rate to a new reference rate. See Note 7 to the Company's consolidated financial statements in Part I, Item 1, Financial Statements, of this Quarterly Report on Form 10-Q for further information on the Company’s Senior Credit Agreement.
Uses of Cash / Cash Requirements
Our material short-term cash requirements primarily include accounts payable, certain employee and retiree benefit-related obligations, operating lease obligations, interest payments on outstanding debt, repayments of borrowing on our revolving credit facility, capital expenditures, and other purchase obligations originating in the normal course of business for inventory purchase orders and contractual service agreements. Our principal capital requirements are to fund our operations' working capital and capital improvements, to provide capital for acquisitions and to strategically allocate capital through repurchases of Company stock. We will continue to invest in growth opportunities as appropriate while focusing on working capital efficiency and profit improvement opportunities to minimize the cash invested to operate our business. We intend to fund our cash requirements through cash generated from operations and, as necessary, from the availability on our revolving credit facility.
In May 2022, the Company's Board of Directors authorized a share repurchase program of up to $200 million of the Company's issued and outstanding common stock. The program has a duration of three years, ending May 2, 2025. Repurchases may be made, from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions, applicable legal requirements, debt covenants and other considerations. Any such repurchases may be executed using open market purchases, privately negotiated agreements or other transactions. The repurchase program may be suspended or discontinued at any time at the Company's discretion. The Company has not made repurchases under the repurchase program to date.
During 2020, we opted to defer remittance of the employer portion of Social Security tax as provided in the Coronavirus, Aid, Relief and Economic Security Act ("CARES Act"), which allowed us to retain $4.4 million in cash during 2020 that would have otherwise been remitted to the federal government. The deferred tax payments were

Table of Contents
required to be repaid in two installments occurring near the end of each year 2021 and 2022, of which $1.9 million was repaid in 2021 and the remaining $2.5 million will be repaid by the end of 2022.
Over the long-term, we expect that future investments, including strategic business opportunities such as acquisitions, may be financed through a number of sources, including internally available cash, availability under our Senior Credit Agreement, new debt financing, the issuance of equity securities, or any combination of the above. All potential acquisitions are evaluated based on our acquisition strategy, which includes the enhancement of our existing products, operations, or capabilities, expanding our access to new products, markets, and customers, with the goal of creating compounding and sustainable stockholder value.
These expectations are forward-looking statements based upon currently available information and may change if conditions in the credit and equity markets deteriorate or other circumstances change. To the extent that operating cash flows are lower than current levels, or sources of financing are not available or not available at acceptable terms, our future liquidity may be adversely affected.
Except as disclosed above, there have been no material changes in our cash requirements since December 31, 2021, the end of fiscal year 2021. See Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2021.
Cash Flows

Cash (used in) provided by: |  |  |
Operating activities of continuing operations | $ | (7,754) |  |  | $ | (1,214) |
Investing activities of continuing operations | (4,402) |  |  | 22,600 |
Financing activities of continuing operations | 15,039 |  |  | (30,388) |

Effect of foreign exchange rate changes | (159) |  |  | (134) |
Net increase (decrease) in cash and cash equivalents | $ | 2,724 |  |  | $ | (11,323) |

Operating Activities
Net cash used in operating activities of continuing operations for the three months ended March 31, 2022 of $7.7 million consisted of income from continuing operations of $15.5 million and non-cash net charges totaling $10.3 million, which include depreciation, amortization, stock compensation, exit activity costs and other non-cash charges, offset by a $33.5 million investment in working capital and other net assets. The investment in working capital and other net assets was due to increases in inventory as a result of provisioning for potential supply chain disruptions and raw material and freight costs, along with an increase in accounts receivable as the result of seasonal increases in demand and a decrease in accounts payable as the result of timing of vendor payments. This was offset by an increase in accrued expenses and other non-current liabilities due to an increase in unbilled project revenues.
Net cash used in operating activities of continuing operations for the three months ended March 31, 2021 of $1.2 million consisted of income from continuing operations of $10.5 million and non-cash net charges totaling $11.4 million, which include depreciation, amortization, stock compensation, exit activity costs and other non-cash charges, offset by a $23.1 million investment in working capital and other net assets. The investment in net working capital and other net assets was largely driven by an increase in inventory due to strong sales demand in our Residential segment and rising raw material prices, along with a decrease in accrued expenses correlated to payments made during the quarter under the Company's performance based incentive programs.
Investing Activities
Net cash used in investing activities of continuing operations for the three months ended March 31, 2022 of $4.4 million was primarily due to capital expenditures of $4.4 million.

Financing Activities
Net cash provided by financing activities of continuing operations for the three months ended March 31, 2022 of $15.0 million was the result of $47.5 million in proceeds from borrowing on our long-term credit facility, offset by $29.0 million in payments on long-term debt and $3.5 million of common stock repurchases related to the net settlement of tax obligations for participants in the Company's equity incentive plans.
Net cash used in financing activities of continuing operations for the three months ended March 31, 2021 of $30.4 million was primarily the result of $46.6 million in payments on long-term debt and $4.7 million of common stock repurchases related to the net settlement of tax obligations for participants in the Company's equity incentive plans, offset by $20.0 million in proceeds from long-term debt and $0.9 million from the issuance of common stock from stock option exercises during the period.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
We are subject to litigation from time to time in the ordinary course of business, however, there is no current material pending litigation to which we are a party and no material legal proceedings were terminated, settled, or otherwise resolved during the fourth quarter of the year ended December 31, 2021. other than ordinary, routine litigation incidental to its business. The Company maintains liability insurance against risks arising out of the normal course of business.
Item 1A. Risk Factors
In addition to the other information set forth in this report, you should carefully consider the risks discussed in “Part I, Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021. These risks and uncertainties have the potential to materially affect our business, financial condition, results of operation, cash flows, and future prospects. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may materially adversely impact our business, financial condition, or operating results. During the quarter ended March 31, 2022, there have been no material changes to the risk factors previously disclosed under Part I, Item 1A. “Risk Factors” in our 2021 Annual Report on Form 10-K, except as follows.
Macroeconomic factors outside of our control may adversely affect our business, our industry, and the businesses and industries of many of our customer and suppliers.
Macroeconomic factors have a significant impact on our business, customer demand and the availability of credit and other capital, affecting our ability to generate profitable margins. Our operations are subject to the effects of domestic and international economic conditions, including global industrial production rates, inflation, deflation, interest rates, availability of capital, debt levels, consumer spending, energy availability, commodity prices, and the effects of governmental initiatives to manage economic conditions, including government monetary and trade policies, tax laws and regulations. Tariffs placed on imported products used by our customers, such as solar panels, could impact cost and availability of these products to our customers which could impact the demand for our products or services. In addition, fluctuations in the U.S. dollar impact the prices we charge and costs we incur to export and import products. We are unable to predict the impact on our business of changes in domestic and international economic conditions. We currently face challenging market conditions, and domestic or global economies, or certain industry sectors of those economies that are key to our sales, may further deteriorate, which could result in a corresponding decrease in demand for our products and negatively impact our results of operations and financial condition.
In addition, the United States currently imposes antidumping and countervailing duties on certain imported solar panels and components from certain countries in Southeast Asia. The antidumping and countervailing duties can change over time pursuant to annual reviews conducted by the U.S. Department of Commerce ("USDOC"), and a change in duty rates could have an adverse impact on our operating results. In early 2022, the USDOC was petitioned to investigate alleged circumvention of antidumping and countervailing duties on Chinese imports of solar panels and components produced in other countries in Southeast Asia. In March 2022, the USDOC announced that it would investigate the circumvention alleged in the petition. As the timing and progress of many of our customers’ projects depend upon the supply of solar panels and components, our operating results could be adversely impacted by any negative circumvention determinations made by the USDOC.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
In May 2022, the Company's Board of Directors authorized a share repurchase program of up to $200 million of the Company's issued and outstanding common stock. The program has a duration of three years, ending May 2, 2025. Repurchases may be made, from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions, applicable legal requirements, debt covenants and other considerations. Any such repurchases may be executed using open market purchases, privately negotiated agreements or other transactions. The repurchase program may be suspended or discontinued at any time at the Company's discretion. The Company has not made repurchases under the repurchase program to date.
