Inc. (the &ldquo;Company&rdquo;) in accordance with accounting principles generally accepted in the United States of America for
interim financial information, pursuant to the rules and regulations of the Securities and Exchange Commission. Pursuant to these
rules and regulations, certain financial information and footnote disclosures normally included in the financial statements have
been condensed or omitted. However, in the opinion of management, the financial statements include all adjustments, consisting
of normal recurring accruals, necessary for a fair presentation of the financial position, results of operations and cash flows
of the interim periods presented. </font>Operating results for the interim periods presented are not necessarily indicative of
results to be expected for the full year or for any other interim period, due to variability in customer purchasing patterns and
seasonal, operating and other factors. <font style="color: black">These condensed financial statements should be read in conjunction

statements, management is required to make estimates and assumptions that affect reported amounts of assets and liabilities and
related revenues and expenses during the reporting periods. As future events and their effects cannot be determined with precision,
actual results could differ significantly from these estimates.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">In January 2017, the FASB issued ASU 2017-04,
Intangibles-Goodwill, which offers amended guidance to simplify the accounting for goodwill impairment by removing Step 2 of the
goodwill impairment test. A goodwill impairment will now be measured as the amount by which a reporting unit&rsquo;s carrying value
exceeds its fair value, limited to the amount of goodwill allocated to that reporting unit. This guidance is to be applied on a
prospective basis effective for the Company&rsquo;s interim and annual periods beginning after December 15, 2019. The new guidance
is effective for the Company beginning in the first quarter of fiscal 2021. The adoption of ASU 2017-04 in the first quarter of
fiscal 2021 did not have a material impact on the Company&rsquo;s financial statements.</p>

of Credit Losses on Financial Instruments. In November 2018, the FASB issued update ASU 2018-19 that clarifies the scope of the
standard in the amendments in ASU 2016-13. This guidance introduces a new model for recognizing credit losses on financial instruments
based on an estimate of current expected credit losses. Financial instruments impacted include accounts receivable, trade receivables,
other financial assets measured at amortized cost and other off-balance sheet credit exposures. The new guidance is effective for
the Company beginning in the first quarter of fiscal 2023, with early adoption permitted. The Company is evaluating the impact
of the adoption of ASU 2016-13 on our financial statements.</p>

employees to purchase shares of the Company&rsquo;s common stock at a discount through payroll deductions. The ESPP is available
to all employees subject to certain eligibility requirements. Terms of the ESPP provide that participating employees may purchase
the Company&rsquo;s common stock on a voluntary after-tax basis. Employees may purchase the Company&rsquo;s common stock at a price
that is no less than the lower of 85% of the fair market value of one share of common stock at the beginning or end of each stock
purchase period or phase. The ESPP is carried out in six-month phases, with phases beginning on January 1 and July 1 of each calendar
year. For the phases that ended on December 31, 2020 and December 31, 2019, employees purchased 15,011 and 15,107 shares at a price
of $11.93 and $11.23 per share, respectively. After the employee purchase on December 31, 2020, 204,612 shares of common stock
were available for future purchase under the ESPP.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">Net sales include products and shipping and
handling charges. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring
products. All revenue is recognized when the Company satisfies its performance obligations under the contract. The Company recognizes
revenue by transferring the promised products to the customer, with substantially all revenue recognized at the point in time the
customer obtains control of the products. The Company recognizes revenue for shipping and handling charges at the time the products
are delivered to or picked up by the customer. The majority of the Company&rsquo;s contracts have a single performance obligation
and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and
remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.</p>

the &ldquo;Company&rdquo;) designs, manufactures, and distributes fiber optic management, protection and delivery products for
communications networks. Our &ldquo;fiber to the anywhere&rdquo; platform serves the unique requirements of leading Broadband Service
Providers in the United States (&ldquo;U.S.&rdquo;), which include Community Broadband, MSO&rsquo;s, and National Carriers, while
also serving the broadband needs of the International markets, primarily countries in the Caribbean, Canada, and Central and South
America. These customers are collectively included in Broadband Service Providers. The Company also provides contract manufacturing
services for its Legacy customers which include original equipment manufacturers (OEM) requiring copper and fiber cable assemblies
built to their specifications. </p>

unserved or underserved rural communities that receive voice, video and data services from independent telephone companies. By
aligning its in-house engineering and technical knowledge alongside its customers, the Company has been able to develop, customize
and enhance products from design through production. Final build and assembly of the Company&rsquo;s products is completed at Clearfield&rsquo;s
manufacturing facilities in Brooklyn Park, Minnesota, and Tijuana, Mexico, with manufacturing support from a network of domestic
and global manufacturing partners. Clearfield specializes in producing these products on both a quick-turn and scheduled delivery
basis. The Company deploys a hybrid sales model with some sales made directly to customers, some made through two-tier distribution
(channel) partners, sales agents and manufacturing representatives, and sales through original equipment suppliers who private
label their products.</p>

to the COVID-19 pandemic, Clearfield&rsquo;s operations are classified as part of the Cybersecurity and Infrastructure Security
Agency (&ldquo;CISA&rdquo;) critical infrastructure sector and similar categorization in Minnesota. In March 2020, we transitioned
our corporate employees at our Brooklyn Park headquarters to remote work arrangements and they currently continue remote work.
In accordance with the Centers for Disease Control and Prevention (&ldquo;CDC&rdquo;) and World Health Organization (&ldquo;WHO&rdquo;)
guidelines, we implemented and have continued health and safety measures for the production staff that remain onsite at our Brooklyn
Park facility. We have maintained our manufacturing capacity in Brooklyn Park with these personnel at near historic levels. Similarly,
we have implemented the recommended health and safety measures for the production staff that remains onsite at our Tijuana, Mexico
manufacturing facilities. Throughout the COVID-19 pandemic, the Company has closely monitored the operations and staffing levels
at its Brooklyn Park facility and its two manufacturing facilities in Tijuana, Mexico.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">Due to the risks to timely supply of materials
to our facilities, we have taken multiple actions to ensure sufficient safety stock inventory levels at both our Minnesota and
Mexico facilities. Additionally, we made the decision to maximize the availability of all product lines at all three of our plants
by assuring that each location can manufacture across our broad product portfolio. These actions, combined with our historic practice
of dual sourcing most of our components, has positioned us to meet our obligations to customers and to fulfill our order backlog
going forward. However, in the event of serious border restrictions or border delays, component material shortages, supply chain
transportation delays, or other serious disruption in our supply chain, we may experience diminished or temporarily suspended operations,
longer lead times than typical for product deliveries, or temporarily suspended product deliveries, which would result in delayed
or reduced revenue from the affected orders in production and higher operating costs.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">Net sales for the second quarter of fiscal 2021
ended March 31, 2021 were $29,692,000, an increase of approximately 45% or $9,283,000, from net sales of $20,409,000 for the second
quarter of fiscal 2020. Net sales to Broadband Service Providers were $28,934,000 in the second quarter of fiscal 2021 versus $19,642,000
in the same period of fiscal 2020. Among this group, the Company recorded $1,948<font style="color: black">,000 </font>in International
sales for the second quarter of fiscal 2021 versus $919,000 in the same period of fiscal 2020. Net sales to Legacy customers were
$758,000 in the second quarter of fiscal 2021 versus $766,000 in the same period of fiscal 2020. The Company allocates sales from
external customers to geographic areas based on the location to which the product is transported. Accordingly, International sales
represented 7% and 5% of total net sales for the second quarter of fiscal 2021 and 2020, respectively.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">&nbsp;</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.5in; margin: 0pt 0">The increase in net sales for the quarter ended
March 31, 2021 of $9,283,000 compared to the quarter ended March 31, 2020 was driven primarily by increased sales to Community
Broadband Service Providers, MSO and International customers of $8,296,000, $1,581,000, and $1,029,000, respectively. Offsetting
this was decreased sales to Tier 1 customers of $1,623,000. Net sales to Legacy customers remained relatively consistent over this
period. The increase to Community Broadband and MSO customers was due to continuing increased demand for fiber connectivity products
in response to COVID-19 driven by customers accelerating their purchasing decisions and deployment schedules of our fiber optic
solutions and the need for high-speed broadband required in the work from anywhere environment. The increase in International sales
was driven by government funding of deployments within those markets. The decrease in sales to Tier 1 customers is due to COVID-19
constraints limiting the deployment of fiber products into the access part of Tier 1 networks.</p>

<p style="font-size: 10pt; text-align: justify; text-indent: 0.5in; margin: 0pt 0">Revenue from customers is obtained from purchase
orders submitted from time to time, with a limited number of customers recently issuing purchase orders for longer time frames.
Accordingly, the Company&rsquo;s ability to predict orders in future periods or trends affecting orders in future periods is limited.
The Company&rsquo;s ability to predict revenue has become further limited by potential disruption to its supply chains or changes
in customer ordering patterns due to COVID-19, global supply chain issues and the impact of government programs. The Company&rsquo;s
ability to recognize revenue in the future for customer orders will depend on the Company&rsquo;s ability to manufacture and deliver
products to the customers and fulfill its other contractual obligations.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"><font style="color: black">Cost of sales for
the second quarter of fiscal 2021 was $16,750,000, an increase of $4,493,000, or 37%, from $12,257,000 in the comparable period
of fiscal 2020. Gross profit percent was 43.6% of net sales in the second quarter of fiscal 2021, an increase from 39.9% of net
sales for the second quarter of fiscal 2020. Gross profit increased $4,790,000 or 59%, to $12,942,000 for the three months ended
March 31, 2021 from $8,151,000 in the comparable period in fiscal 2020. </font>The increase in gross profit in the second quarter
of fiscal 2021 was due to increased volume of net sales described above while the increase in gross profit percent was primarily
due to a favorable product mix and cost reduction efforts across the Company&rsquo;s product lines, including greater use of its
Mexico manufacturing plants and efficiencies realized from higher sales volumes. In the second quarter of fiscal 2021, the Company
did not experience any significant impacts on cost of sales due to COVID-19.</p>

2020 second quarter. The increase in expense in the second quarter of fiscal 2021 consists primarily of increases of $1,405,000
in compensation expense due to additional headcount and increased wages and performance compensation accruals driven by higher
net sales, and increased stock compensation expense of $231,000, offset by a recovery of bad debt expense of $210,000 and a decrease

ended March 31, 2021 of $16,998,000 compared to the six months ended March 31, 2020 is primarily attributable to an increase in
sales to Community Broadband, MSO and International customers of $16,490,000, $2,282,000 and $907,000, respectively. This was
offset by decreased sales to Tier 1 and Legacy customers of $1,999,000, and $683,000, respectively. The increase to Community
Broadband and MSO customers was due to increased demand in response to COVID-19 driven by customers accelerating their purchasing
decisions and deployment schedules of our fiber optic solutions and the need for high-speed broadband required in the work from
anywhere environment. The increase in International sales was driven by government funding of deployments within those markets.
The decrease in sales to Tier 1 customers is the result of COVID-19 constraints limiting the deployment of fiber products into
the access part of the network.</p>

$15,879,000 in the comparable period in fiscal 2020. </font>The increase in gross profit in the six months ended March 31, 2021
was due to increased volume of net sales described above and a higher gross profit percent. The increase in gross profit percent
was primarily due to favorable product mix and cost reduction efforts across the Company&rsquo;s product lines, including greater
use of its Mexico manufacturing plants and efficiencies realized from higher sales volumes. In the six months ended March 31, 2021,
the Company did not experience any significant impacts on cost of sales due to COVID-19.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">We purchase critical components for our products, including injected

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">We depend on the ability of these third-party suppliers to secure
a sufficient supply of raw materials and maintain sufficient manufacturing and shipping capacity. The global supply chain for raw
materials critical to our products, such as resin used to manufacture plastics and fiber optic cable, recently has suffered shortages,
shipping delays and shipping shortages. This has led some manufacturers who depend on these raw materials to experience shortages,
delivery delays and price increases for both the raw materials and shipping, with the corresponding consequence that these manufacturers
may be delayed in delivering products to their customers or may charge higher prices for these products, or there may be increased
shipping costs associated with the products. Some manufacturers have allocated short supply among their customers. Additionally,
the COVID-19 pandemic has driven demand for certain goods that have exacerbated these disruptions as supply has not kept pace with
demand. We believe these global supply chain issues will persist and will likely intensify in 2021 due to the complex and compounding
problems associated with shortages of personnel due to the COVID-19 pandemic, backlogs at ports, shortages of shipping containers,
freezing weather in Texas affecting the petrochemical industry, the blockage of the Suez Canal affecting the flow of trade, and
other logistical issues.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">In the first half of fiscal 2021, Clearfield has experienced and
expects to continue to experience increased demand for its products from its customers, putting pressure on Clearfield&rsquo;s
supply chain to meet demand amidst these global issues. While we have not experienced significant increases in costs or delays
in obtaining the materials and components for our products from our suppliers, we cannot assure you that we will not experience
these costs or delays in the future. Clearfield&rsquo;s ability to recognize revenue in the future for customer orders will depend
on our ability to manufacture and deliver products to the customers and fulfill its other contractual obligations. Our ability
to meet expected future customer demand for our products will in turn depend upon our suppliers receiving timely and adequate supply
of raw materials to be able to produce the critical materials and components they supply to us. Although we place a high value
on long-term relationships with our suppliers, generally we do not have long-term supply contracts but instead conduct business
on an order-by-order basis. Therefore, we also compete with other companies for the production capacity of manufacturers of the
materials and components we need for our products. We also are exposed to potentially increasing costs associated with the materials
and components we purchase from suppliers or increased costs associated with shipping generally. We may attempt to mitigate the
effect of increases in our cost of goods sold through sourcing or stocking initiatives and by selectively increasing the prices
of our products. However, we may be unable to fully pass on these costs to our customers.</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">&nbsp;</p>

<p style="margin: 0pt 0; font-size: 10pt; text-align: justify">The reduction of available production capacity among our suppliers,
their failures to meet production deadlines or increases to us in their manufacturing or shipping costs may impact our ability
to deliver quality products to our customers on a timely basis, make our products less competitive due to extended delivery times
or increased price, negatively impact our customer or distributor relationships, and result in lower net sales and profit.</p>

(the &amp;#x201c;Company&amp;#x201d;) in accordance with accounting principles generally accepted in the United States of America for interim financial information, pursuant to the rules and regulations of the Securities and Exchange Commission. Pursuant to these rules and regulations, certain financial information and footnote disclosures normally included in the financial statements have been condensed or omitted. However, in the opinion of management, the financial statements include all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the financial position, results of operations and cash flows of the interim periods presented. &lt;/div&gt;Operating results for the interim periods presented are &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; necessarily indicative of results to be expected for the full year or for any other interim period, due to variability in customer purchasing patterns and seasonal, operating and other factors. &lt;div style="display: inline; color: black"&gt;These condensed financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;10&lt;/div&gt;-K for the year ended &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; September 30, 2020.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;In preparation of the Company's financial statements, management is required to make estimates and assumptions that affect reported amounts of assets and liabilities and related revenues and expenses during the reporting periods. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;For the purposes of comparability, certain prior period amounts have been reclassified to conform to current period classification. There was &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;no&lt;/div&gt; impact to prior period net income or shareholders' equity.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;New Accounting Pronouncements&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;In &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; January 2017, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2017&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;04,&lt;/div&gt; Intangibles-Goodwill, which offers amended guidance to simplify the accounting for goodwill impairment by removing Step &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2&lt;/div&gt; of the goodwill impairment test. A goodwill impairment will now be measured as the amount by which a reporting unit's carrying value exceeds its fair value, limited to the amount of goodwill allocated to that reporting unit. This guidance is to be applied on a prospective basis effective for the Company's interim and annual periods beginning after &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; December 15, 2019. &lt;/div&gt;The new guidance is effective for the Company beginning in the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; quarter of fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021.&lt;/div&gt; The adoption of ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2017&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;04&lt;/div&gt; in the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; quarter of fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2021&lt;/div&gt; did &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; have a material impact on the Company's financial statements.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;In &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; June 2016, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font: inherit;"&gt;13,&lt;/div&gt; Measurement of Credit Losses on Financial Instruments.

Financial instruments impacted include accounts receivable, trade receivables, other financial assets measured at amortized cost and other off-balance sheet credit exposures. The new guidance is effective for the Company beginning in the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;first&lt;/div&gt; quarter of fiscal &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;2023,&lt;/div&gt; with early adoption permitted.

The lease term is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;ten&lt;/div&gt; years and &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt; months, ending on &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; February 28, 2025.&amp;nbsp; &lt;/div&gt;Upon proper notice and payment of a termination fee of approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;$249,000,&lt;/div&gt; the Company has a &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;one&lt;/div&gt;-time option to terminate the lease effective as of the last day of the &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;eighth&lt;/div&gt; year of the term after the Company commenced paying base rent. The renewal and termination options have &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; been included within the lease term because it is &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;not&lt;/div&gt; reasonably certain that the Company will exercise either option.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; October 9, 2020, &lt;/div&gt;the Company entered into an indirect lease arrangement for its original &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;46,000&lt;/div&gt; square foot manufacturing facility in Tijuana, Mexico.

This lease contains a written option to renew and rent payments that increase annually based on U.S. inflation for the preceding &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;12&lt;/div&gt; months.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 14 --&gt;    &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;On &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; February 12, 2020, &lt;/div&gt;the Company entered into an indirect lease arrangement for an additional &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;52,000&lt;/div&gt; square foot manufacturing facility in Tijuana, Mexico. The lease term is approximately &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;42&lt;/div&gt; months and commenced on &lt;div style="display: inline; font-style: italic; font: inherit;"&gt; February 12, 2020. &lt;/div&gt;The lease contains written options to renew for &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;two&lt;/div&gt; additional consecutive periods of &lt;div style="display: inline; font-style: italic; font: inherit;"&gt;three&lt;/div&gt; years each.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;Right-of-use lease assets and lease liabilities are recognized as of the commencement date based on the present value of the remaining lease payments over the lease term which includes renewal periods the Company is reasonably certain to exercise.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. All revenue is recognized when the Company satisfies its performance obligations under the contract. The Company recognizes revenue by transferring the promised products to the customer, with substantially all revenue recognized at the point in time the customer obtains control of the products. The Company recognizes revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. The majority of the Company's contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Disaggregation of Revenue&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in"&gt;The Company allocates sales from external customers to geographic areas based on the location to which the product is transported.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. All revenue is recognized when the Company satisfies its performance obligations under the contract. The Company recognizes revenue by transferring the promised products to the customer, with substantially all revenue recognized at the point in time the customer obtains control of the products. The Company recognizes revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. The majority of the Company's contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.</div> <div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">&nbsp;</div> <div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"><div style="display: inline; font-weight: bold;">Disaggregation of Revenue</div></div> <div style=" margin: 0pt 0; font-size: 10pt">&nbsp;</div> <div style=" margin: 0pt 0; font-size: 10pt; text-align: justify; text-indent: 0.5in">The Company allocates sales from external customers to geographic areas based on the location to which the product is transported.
