SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES |
Accounting estimates | Accounting estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. The amount reported as a contractual allowance for rebates involves examination of past historical trends related to sales to customers and the related credits issued once contractual obligations of the customers have been met. The establishment of a liability for future claims of rebates against sales in the current period requires that the Company has an understanding of the relevant sales with respect to product categories, sales distribution channels, and the likelihood of contractual obligations being satisfied.
Cash and cash equivalents | Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents include cash, money market accounts, and investments with original maturities of three months or less.
Accounts receivable | Accounts receivable The Company records trade receivables when revenue is recognized. No product has been consigned to customers. The Company’s allowance for doubtful accounts is primarily determined by review of specific trade receivables. Those accounts that are doubtful of collection are included in the allowance. This provision is reviewed to determine the adequacy of the allowance for doubtful accounts. Trade receivables are charged off when there is certainty as to their being uncollectible. Trade receivables are considered delinquent when payment has not been made within contract terms. The allowance for doubtful accounts was $675,208 and $352,217 as of December 31, 2022 and 2021, respectively. The Company requires certain customers to make a prepayment prior to beginning production or shipment of their order. Customers may apply such prepayments to their outstanding invoices or pay the invoice and continue to carry forward the deposit for future orders. Such amounts are included in Other accrued liabilities on the Balance Sheets and are shown in Note 7, Other Accrued Liabilities. The Company records an allowance for estimated returns as a reduction to Accounts receivable and Gross sales. Historically, returns have been insignificant.
Inventories | Inventories Inventories are valued at the lower of cost or net realizable value, with cost being determined using actual average cost. The Company compares the average cost to the net realizable value and records the lower value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Management considers such factors as the amount of inventory on hand and in the distribution channel, estimated time to sell such inventory, the shelf life of inventory, and current market conditions when determining excess or obsolete inventories. Once inventory items are deemed to be either excess or obsolete, they are written down to their net realizable value.
Investments in debt and equity securities | Investments in debt and equity securities The Company holds high-grade mutual funds and debt and equity securities as investments. These assets are readily marketable and are carried at fair value as of the date of the Balance Sheets. Net unrealized and realized gains or losses on these investments are reflected separately on the Statements of Operations. Realized gains or losses on investments are recognized using the specific identification method.
Property, plant, and equipment | Property, plant, and equipment Property, plant, and equipment are stated at cost. Expenditures for maintenance and repairs are charged to operations as incurred. Cost includes major expenditures for improvements and replacements which extend useful lives or increase capacity and interest cost associated with significant capital additions. Gains or losses from disposals are included in Interest and other income. The Company's property, plant, and equipment primarily consist of buildings, land, assembly equipment, molding machines, molds, office equipment, furniture, and fixtures. Depreciation and amortization are calculated using the straight-line method over the following useful lives: ​
​ | ​ | ​
Production equipment |  | 3 to 13 years
Office furniture and equipment |  | 3 to 10 years
Buildings |  | 39 years
Building improvements |  | 15 years
​
Long-lived assets | Long-lived assets The Company assesses the recoverability of long-lived assets using an assessment of the estimated undiscounted future cash flows related to such assets. In the event that assets are found to be carried at amounts which are in excess of estimated gross future cash flows, the assets will be adjusted for impairment to a level commensurate with fair value determined using a discounted cash flow analysis or appraised values of the underlying assets.
Fair value measurements | Fair value measurements For assets and liabilities that are measured using quoted prices in active markets, total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are valued by reference to similar assets or liabilities, adjusted for contract restrictions and other terms specific to that asset or liability. For these items, a significant portion of fair value is derived by reference to quoted prices of similar assets or liabilities in active markets. For all remaining assets and liabilities, fair value is derived using a fair value model, such as a discounted cash flow model or Black-Scholes model.
Financial instruments | Financial instruments The Company estimates the fair value of financial instruments through the use of public market prices, quotes from financial institutions, and other available information. Judgment is required in interpreting data to develop estimates of fair value and, accordingly, amounts are not necessarily indicative of the amounts that could be realized in a current market exchange. Short-term financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and other liabilities, consist primarily of instruments without extended maturities, the fair value of which, based on Management’s estimates, equals their recorded values. Investments in debt and equity securities consist primarily of individual equity securities and mutual funds and are reported at their fair value based upon quoted prices in active markets. Investments in certificates of deposit (CD) with original maturities of greater than three months are reported at their estimated fair value based upon the duration of the CD and the interest rate earned on the CD versus current interest rates of similar duration CDs. The fair value of long-term liabilities, based on Management’s estimates, approximates their reported values.
Concentration risks | Concentration risks The Company’s financial instruments exposed to concentrations of credit risk consist primarily of cash, cash equivalents, certificates of deposit, exchange-traded and closed-end funds, mutual funds, equity securities, and accounts receivable. Cash balances, some of which exceed federally insured limits, are maintained in financial institutions; however, Management believes the institutions are of high credit quality. The majority of accounts receivable are due from companies that are well-established entities. The Company assesses market risk in equity securities through consultation with its outside investment advisors. Management is responsible for directing investment activity based on current economic conditions. Management considers any exposure from concentrations of credit risks to be limited. The following table reflects our significant customers in 2022, 2021, and 2020: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | Years Ended December 31, |
​ |  | ​ | 2022 |  | 2021 |  | 2020 |
Number of significant customers |  |  | ​ | 4 |  | ​ | 1 |  | ​ | 2 | ​
Aggregate dollar amount of net sales to significant customers | ​ | ​ | $ | 66.4 million | ​ | $ | 113.7 million | ​ | $ | 41.6 million | ​
Percentage of net sales to significant customers | ​ | ​ | ​ | 70.0 | % | ​ | 60.3 | % | ​ | 50.6 | %
​ The Company increased its allowance for doubtful accounts by $323 thousand in 2022. The Company manufactures some of its products in Little Elm, Texas, as well as utilizing manufacturers in China. The Company obtained roughly 91.6% of its products in 2022 from its Chinese manufacturers. Purchases from Chinese manufacturers aggregated 92% and 85.2% of products in 2021 and 2020, respectively. In the event that the Company becomes unable to purchase products from its Chinese manufacturers, the Company may need to find an alternate manufacturer for its blood collection set, IV catheter, Patient Safe® syringe, 0.5mL insulin syringe, 0.5mL autodisable syringe, and 2mL, 5mL, and 10mL syringes, and would increase domestic production for the 1mL and 3mL syringes and EasyPoint® needles.
Revenue recognition | Revenue recognition The Company recognizes revenue when control of performance obligations passes to the customer, generally when the product ships. Payments from customers with approved credit terms are typically due 30 days from the invoice date. Under certain contracts, revenue is recorded on the basis of sales price to distributors, less contractual pricing allowances. Contractual pricing allowances consist of: (i) rebates granted to distributors who provide tracking reports which show, among other things, the facility that purchased the products, and (ii) a provision for estimated contractual pricing allowances for products for which the Company has not received tracking reports. When rebates are issued, they are applied against the customer’s receivable balance. Distributors receive a rebate for the difference between the Wholesale Acquisition Cost and the appropriate contract price as reflected on a tracking report provided by the distributor to the Company. If product is sold by a distributor to an entity that has no contract, there is a standard rebate (lower than a contracted rebate) given to the distributor. One of the purposes of the rebate is to encourage distributors to submit tracking reports to the Company. The provision for contractual pricing allowances is recognized in the period the related sales are recognized and is reviewed at the end of each quarter and adjusted for changes in levels of products for which there is no tracking report. Additionally, if it becomes clear that tracking reports will not be provided by individual distributors, the provision is further adjusted. The estimated contractual allowance is included in Accounts payable in the Balance Sheets and deducted from Revenues in the Statements of Operations. Accounts payable included estimated contractual allowances for $3.0 million and $6.2 million as of December 31, 2022 and 2021, respectively. The terms and conditions of contractual pricing allowances are governed by contracts between the Company and its distributors. Revenue for shipments directly to end-users is recognized when title and risk of ownership pass from the Company. End-users do not receive any contractual allowances on their purchases. Any product shipped or distributed for evaluation purposes is expensed. The Company provides product warranties that: i) the products are fit for medical use as generally defined within the boundaries of United States FDA approval; ii) the products are not defective; and iii) the products will conform to the descriptions set forth in their respective labeling, provided that they are used in accordance with such labeling and the Company’s written directions for use. The Company has historically not incurred significant warranty claims. The Company’s domestic return policy provides that a customer may return incorrect shipments within 10 days following arrival at the distributor’s facility. In all such cases, the distributor must obtain an authorization code from the Company and affix the code to the returned product. The Company’s domestic return policy also generally provides that a customer may return product that is overstocked. Overstocking returns are limited to two times in each 12-month period up to 1% of distributor’s total purchase of products for the prior 12-month period. All product overstocks and returns are subject to inspection and acceptance by the Company. The Company has not historically incurred significant returns. The Company’s international distribution agreements generally do not provide for any returns. The Company requires certain customers to pay in advance of product shipment. Such prepayments from customers are recorded in Other accrued liabilities and are generally recognized as revenue upon shipment of the product. The Company periodically recognizes revenue from licensing agreements. If the Company licenses its products for sale and the customers of the sublicensee are not known to the Company, the Company is obligated to pay Thomas J. Shaw, the owner of certain patented technology, fifty percent (50%) of such revenue pursuant to the terms of the Technology License Agreement between the Company and Mr. Shaw. Disaggregated information of revenue recognized from contracts with customers and licensing fees recognized are as follows: ​

Income taxes | Income taxes The Company evaluates tax positions taken or expected to be taken in a tax return for recognition in the financial statements based on whether it is “more-likely-than-not” that a tax position will be sustained based upon the technical merits of the position. Measurement of the tax position is based upon the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company provides for deferred income taxes through utilizing an asset and liability approach for financial accounting and reporting based on the tax effects of differences between the financial statement and tax bases of assets and liabilities, based on enacted rates expected to be in effect when such differences reverse in future periods. Deferred tax assets are periodically reviewed for realizability. In prior periods, the Company established a valuation allowance for its net deferred tax asset as future taxable income which could not be reasonably assured. During the quarter ended June 30, 2020, the Company released its valuation allowance based on available evidence supporting that its deferred tax assets will be realized in full.
Earnings per share | Earnings per share The Company computes basic earnings per share (“EPS”) by dividing net earnings for the period (adjusted for any cumulative dividends for the period) by the weighted average number of common shares outstanding during the period. Diluted EPS includes the determinants of basic EPS and, in addition, reflects the dilutive effect, if any, of the common stock deliverable pursuant to stock options and/or common stock issuable upon the conversion of convertible preferred stock. ​ The calculation of diluted EPS under the treasury stock method included the following shares in 2022, 2021, and 2020: ​
​ | ​ | ​ | ​ | ​ | ​
​ | Years Ended December 31,
​ | 2022 |  | 2021 |  | 2020
Common Stock underlying issued and outstanding stock options | 65,597 | ​ | 141,435 | ​ | 131,347
Common stock issuable upon the conversion of convertible preferred shares | — | ​ | 232,445 | ​ | —
​ | 65,597 | ​ | 373,880 | ​ | 131,347
​ In both 2022 and 2020, preferred stock was excluded from the calculation of diluted EPS because the effect was antidilutive. ​ The potential dilution, if any, is shown on the following schedule: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | Years Ended December 31,
​ |  | ​ | 2022 |  | 2021 |  | 2020
Net income | ​ | ​ | $ | 5,078,557 | ​ | $ | 56,064,241 | ​ | $ | 24,223,013
Preferred stock dividend requirements | ​ | ​ |  | (232,444) | ​ |  | (241,703) | ​ |  | (573,868)
Deemed contribution on extinguishment of preferred stock | ​ | ​ | ​ | — | ​ | ​ | — | ​ | ​ | 2,975,708
Income applicable to common shareholders | ​ | ​ | $ | 4,846,113 | ​ | $ | 55,822,538 | ​ | $ | 26,624,853
Average common shares outstanding | ​ | ​ |  | 32,896,348 | ​ |  | 33,870,819 | ​ |  | 33,169,307
Average common and common equivalent shares outstanding — assuming dilution | ​ | ​ |  | 32,961,945 | ​ |  | 34,244,699 | ​ |  | 33,300,654
Basic earnings per share | ​ | ​ | $ | 0.15 | ​ | $ | 1.65 | ​ | $ | 0.80
Diluted earnings per share | ​ | ​ | $ | 0.15 | ​ | $ | 1.63 | ​ | $ | 0.80
​ The FASB Codification 260-10-S99-2, Effect on the Calculation of Earnings per Share for the Redemption or Induced Conversion of Preferred Stock, requires the gain or loss on extinguishment of equity-classified preferred stock to be included in the net income per common stockholder used to calculate earnings per share (similar to the treatment of dividends paid on preferred stock). The difference between (1) the fair value of the consideration transferred to the holders of the preferred stock and (2) the carrying amount of the preferred stock (net of issuance costs) is subtracted from (or added to) net income to arrive at income available to common stockholders in the calculation of earnings per share. The Company has determined to apply this guidance to its accounting treatment of the preferred stock transactions described in Note 20.
Shipping and handling costs | Shipping and handling costs The Company classifies shipping and handling costs as part of Cost of sales in the Statements of Operations.
Share-based Compensation | Share-based Compensation The Company’s share-based payments are accounted for using the Black-Scholes fair value method. The Company generally records share-based compensation expense on a straight-line basis over the requisite service period. The Company records forfeitures as they occur.
Self-insured employee benefit costs | Self-insured employee benefit costs The Company self-insures certain health insurance benefits for its employees under certain policy limits. The Company has additional coverage provided by an insurance company for any individual with claims in excess of $100,000 and/or total plan claims in excess of $1.6 million for the plan year.
Research and development costs | Research and development costs Research and development costs are expensed as incurred.
Leases | Leases The Company determines if an arrangement is a lease at inception. Operating and finance leases are included in Other assets, Other accrued liabilities, and Other long-term liabilities on the Balance Sheets. Right-of-use ("ROU") assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of twelve months or less are not recorded on the Balance Sheets; however, rent expense is recognized on a straight-line basis over the lease term. As of December 31, 2022, all leases have expired.
Technology Investment Agreement (TIA) | Technology Investment Agreement (TIA) Effective July 1, 2020, the Company entered into a Technology Investment Agreement (“TIA”) with the United States Government Department of Defense, U.S. Army Contracting Command-Aberdeen Proving Ground, Natick Contracting Division & Edgewood Contracting Division (ACC-APG, NCD & ECD) on behalf of the Biomedical Advanced Research and Development Authority (BARDA), as amended, for $81,029,518 in government funding for expanding the Company’s domestic production of needles and syringes. Pursuant to the terms of the TIA, the Company has made significant additions to its facilities which has allowed the Company to increase domestic production capacity. For further explanation, please refer to Note 22 – Technology Investment Agreement. The amounts set forth as Receivable from Technology Investment Agreement (TIA) on the Balance Sheets represent amounts receivable under the TIA. The amounts may represent advance requests or reimbursement requests for expenditures. As reimbursements are received from the U.S. government for such expenditures, the Company records a deferred liability. In 2021, the deferred liability began to be systematically amortized as a gain over the life of the related property, plant, and equipment and is presented as Other income – TIA on the Statements of Operations. For any reimbursements received for expenditures not capitalized as property, plant, and equipment, Other income – TIA will be recognized in the same period as the expense.
Recently Adopted Pronouncements and Recently Issued Pronouncement | Recently Adopted Pronouncements The Company adopted ASU 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance”. The new standard is intended to provide increased transparency by requiring business entities to disclose information about certain types of government assistance they receive in the notes to the financial statements. ASU 2021-10 also adds a new Topic – ASC 832, Government Assistance – to the FASB’s Codification. Included in the disclosures under the guidance are the nature of the transaction including the nature of the assistance being given, the accounting policies being used to account for the transaction and other provisions of relevance. The guidance is effective for annual periods beginning after December 15, 2021, with early adoption permitted. The Company has determined that the guidance did not have a material impact on its financial statements as such disclosures surrounding the TIA, including the accounting policies used to account for the agreement, have been in place since its inception. ​ Recently Issued Pronouncements In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions”, intended to clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendment also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. ASU No. 2022-03 is effective for public business entities for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted. For all other entities, it is effective for fiscal years, including interim periods within those fiscal years beginning after December 15, 2024. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company is evaluating the adoption of the amendments and the potential impact it may have, if any, on its financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”, to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients for contracts that reference LIBOR, if certain criteria are met, that can be applied through December 31, 2022. The Company has determined that the adoption of ASU No. 2020-04 would not have a material impact on its financial statements.
