SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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.

Cash and cash equivalents

For purposes of reporting cash flows, cash and cash equivalents include unrestricted cash, money market accounts, and investments with original maturities of three months or less.

Restricted cash

Amounts pledged as collateral for an underlying letter of credit for equipment is classified as restricted cash. Changes in restricted cash have been presented as investing activities in the Statements of Cash Flows.

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 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 6, Other Accrued Liabilities.

The Company records an allowance for estimated returns as a reduction to Accounts receivable and Gross sales. Historically, returns have been immaterial.

Inventories

Inventories are valued at the lower of cost or market, with cost being determined using actual average cost. The Company compares the average cost to the market price and records the lower value. 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. A reserve is established for any excess or obsolete inventories or they may be written off.

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 property disposals are included in income.

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
Automobiles		7 years

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 of the underlying assets.

The Company’s property, plant, and equipment primarily consist of buildings, land, assembly equipment for syringes, molding machines, molds, office equipment, furniture, and fixtures.

Intangible assets

Intangible assets are stated at cost and consist primarily of intellectual property which is amortized using the straight-line method over 17 years.

Financial instruments

The Company estimates the fair market 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 market 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. The fair value of long-term liabilities, based on Management’s estimates, approximates their reported values.

Concentration risks

The Company’s financial instruments exposed to concentrations of credit risk consist primarily of cash, cash equivalents, 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 which are well-established entities. As a consequence, Management considers any exposure from concentrations of credit risks to be limited.

The following table reflects our significant customers in 2015, 2014, and 2013:

	Years Ended December 31,
	2015			2014			2013
Number of significant customers	2			3			2
Aggregate dollar amount of net sales to significant customers	$	13.5 million		$	16.5 million		$	9.3 million
Percentage of net sales to significant customers	45.7		%	47.9		%	30.2		%

Considering the current economic climate, the Company increased its allowance for doubtful accounts by approximately $70,000 this year.

The Company manufactures syringes in Little Elm, Texas as well as utilizing manufacturers in China. The Company purchases most of its product components from single suppliers, including needle adhesives and packaging materials. There are multiple sources of these materials. The Company obtained roughly 77.7% of its VanishPoint® finished products in 2015 from its primary Chinese manufacturer. Purchases from this Chinese manufacturer aggregated 73.1% and 72.9% of VanishPoint® finished products in 2014 and 2013, respectively. In the event that the Company becomes unable to purchase products from its primary Chinese manufacturer, the Company would need to find an alternate manufacturer for its 0.5mL insulin syringe, its 2mL, 5mL, and 10mL syringes and its autodisable syringe and increase domestic production for 1mL and 3mL syringes.

Revenue recognition

Revenue is recognized for sales when title and risk of ownership passes to the customer, generally upon shipment. 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. Rebates are recorded when issued and 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 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 $3,733,199 and $4,160,099 for 2015 and 2014, 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. Any product shipped or distributed for evaluation purposes is expensed.

Certain distributors have taken rebates to which they are not entitled, such as utilizing a rebate for products not purchased directly from the Company. Major customers said they have ceased the practices resulting in claiming non-contractual rebates. Rebates can only be claimed on purchases made directly from the Company. The Company has established a reserve for the collectability of these non-contractual rebate amounts. The expense for the reserve is recorded in Operating expense, General and administrative. The reserve for such non-contractual deductions is included in the allowance for doubtful accounts. There has been no change to the reserve for contractual rebates in the periods currently presented.

The Company’s domestic return policy is set forth in its standard Distribution Agreement. This 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 will not accept returned goods without a returned goods authorization number. The Company may refund the customer’s money or replace the 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’s international distribution agreements generally do not provide for any returns.

Litigation proceeds

Proceeds from litigation are recognized when realizable. Generally, realization is not reasonably assured and expected until proceeds are collected.

On September 30, 2013, the Company received payment of $7,724,826 (the “Judgment Amount”) from Becton, Dickinson and Company (“BD”) pursuant to a stipulation in the patent infringement case Retractable Technologies, Inc. and Thomas Shaw v. Becton Dickinson and Company, Civil Action No. 2:07-cv-250, in the U.S. District Court for the Eastern District of Texas, Marshall Division. The Judgment Amount was included as income in the second quarter of 2015 due to the conclusion of the case and related appeals. Prior to the second quarter of 2015, the Judgment Amount had been shown as a liability on the balance sheet since the Company was paid the Judgment Amount and the litigation did not come to a final conclusion until the second quarter of 2015.

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. The Company utilized some of its net operating loss carry forwards in 2013 and paid Alternative Minimum Tax on its taxable income. The Company has established a valuation allowance for its net deferred tax asset as future taxable income cannot be reasonably assured. Penalties and interest related to income tax are classified as General and administrative expense and Interest expense, respectively, in the Statements of Operations.

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 or common stock issuable upon the conversion of convertible preferred stock. The calculation of diluted EPS excluded 1,774,520 and 1,305,847 shares of Common Stock underlying issued and outstanding stock options at December 31, 2014 and 2013, respectively, as their effect was antidilutive. The potential dilution, if any, is shown on the following schedule:

	Years Ended December 31,
	2015			2014			2013
Net income (loss)	$	4,314,318		$	(2,354,605	)	$	(6,213,852	)

Diluted earnings (loss) per share	$	0.20		$	(0.12	)	$	(0.26	)

The Financial Accounting Standards Board Accounting Standards 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 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 transaction described in note 20. From a legal standpoint, the transaction was neither a redemption nor conversion pursuant of the terms of the Certificate of Designation, Preferences, Rights and Limitations of the Series IV Class B Convertible Preferred Stock.

Shipping and handling costs

The Company classifies shipping and handling costs as part of Cost of sales in the Statements of Operations.

Research and development costs

Research and development costs are expensed as incurred.

Share-based compensation

The Company’s share-based payments are accounted for using the fair value method. The Company records share-based compensation expense on a straight-line basis over the requisite service period. The Company incurred $52,775 in General and administrative cost related to share-based compensation in 2013. No share-based compensation costs were incurred in 2015 or 2014.

All stock options are fully vested; therefore, all stock option expense has been fully recognized.

Recent Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (topic 842). Under the new ASU, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance lessor accounting is largely unchanged. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. This ASU is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this standard.

In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU amends Topic 740, Income Taxes, requiring deferred tax assets and liabilities to be classified as non-current in the statement of financial position. As required by ASU No. 2015-17, all deferred tax assets and liabilities will be classified as non-current in the Company’s consolidated balance sheets. Effective for public business entities for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The amendments may be applied prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company is currently evaluating the impact of this standard.

In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330) Simplifying the Measurement of Inventory,” which is part of the FASB’s Simplification Initiative. Inventory, including inventory measured at average cost, would be valued at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for the Company’s annual periods and interim periods within those annual periods beginning January 1, 2017. Amendments in this ASU should be applied prospectively with earlier application permitted at the beginning of an interim or annual reporting period. The Company is currently assessing the potential impact of this ASU on its financial statements.

In May 2014, FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”, which provides guidance for revenue recognition. This ASU’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects consideration to which the company expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB voted to delay the effective date of this ASU by one year. The ASU will now be effective commencing with the Company’s quarter ending March 31, 2018. Early adoption of this ASU is allowed no sooner than the original effective date. The Company is currently assessing the potential impact of this ASU on its financial statements.

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements Going Concern (Subtopic 205-40) — Disclosure of Uncertainties about and Entity’s Ability to Continue as a Going Concern”. Currently there is no guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern. This ASU requires management to assess the entity’s ability to continue as a going concern. This guidance is effective for the Company’s annual reporting period ending December 31, 2016 and for subsequent interim periods. Early adoption is permitted. The Company expects to adopt this guidance when effective, and upon adoption, will evaluate going concern based on this guidance.

In April 2015, the FASB issued ASU 2015-03, “Interest—Imputation of Interest”. To simplify presentation of debt issuance costs, the amendments in this ASU would require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in this ASU. This ASU is the final version of Proposed Accounting Standards Update 2014-250—“Interest—Imputation of Interest” (Subtopic 835-30), which has been deleted. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company has no unamortized debt issuance costs.

In May 2010, the Company and an officer’s suit against BD in the U.S. District Court for the Eastern District of Texas, Marshall Division alleging violations of antitrust acts, false advertising, product disparagement, tortious interference, and unfair competition was reopened. The trial commenced on September 9, 2013 in the U.S. District Court for the Eastern District of Texas, Tyler Division, and the jury found that BD illegally engaged in anticompetitive conduct with the intent to acquire or maintain monopoly power in the safety syringe market and engaged in false advertising under the Lanham Act. The jury awarded the Company $113,508,014 in damages, which was trebled pursuant to statute. The Court granted injunctive relief to take effect January 15, 2015. In doing so, the Court found that BD’s business practices limited innovation, including false advertisements that suppressed sales of the VanishPoint®. The specific injunctive relief includes: (1) enjoining BD’s use of “World’s Sharpest Needle” or any similar assertion of superior sharpness; (2) requiring notification to all customers who purchased BD syringe products from July 2, 2004 to date that BD wrongfully claimed that its syringe needles were sharper and that its statement that it had “data on file” was false and misleading; (3) requiring notification to employees, customers, distributors, GPOs, and government agencies that the deadspace of the VanishPoint® has been within ISO standards since 2004 and that BD overstated the deadspace of the VanishPoint® to represent that it was higher than some of BD’s syringes when it was actually less, and that BD’s statement that it had “data on file” was false and misleading, and, in addition, posting this notice on its website for a period of three years; (4) enjoining BD from advertising that its syringe products save medication as compared to VanishPoint® products for a period of three years; (5) requiring notification to all employees, customers, distributors, GPOs, and government agencies that BD’s website, cost calculator, printed materials, and oral representations alleging BD’s syringes save medication as compared to the VanishPoint® were based on false and inaccurate measurement of the VanishPoint®, and, in addition, posting this notice on its website for a period of three years; and (6) requiring the implementation of a comprehensive training program for BD employees and distributors that specifically instructs them not to use old marketing materials and not to make false representations regarding VanishPoint® syringes. Final judgment was entered on January 15, 2015, awarding the Company $340,524,042 in damages and $11,722,823 in attorneys’ fees, as well as granting injunctive relief consistent with the orders as indicated above. The parties stipulated that the amount of litigation costs recoverable by the Company is $295,000. On January 14, 2015, the District Court stayed the portion of the injunctive relief that requires BD to notify end-user customers but also ordered BD to comply with internal correction activities as well as mandatory disclosures as set out above to its employees, customers, distributors and Group Purchasing Organizations. BD filed an appeal of that ruling with the 5th Circuit Court of Appeals and that appeal was denied on February 3, 2015. On February 12, 2015, BD filed a motion to amend the judgment directed most specifically to the issue of award of prejudgment interest. On April 23, 2015, the Court entered an Amended Final Judgment that removed prejudgment interest but kept all other monetary and injunctive relief the same as was granted in the original Final Judgment. BD filed its brief in the appeal on July 20, 2015. The Company filed its responsive brief on September 18, 2015 and BD filed its brief in reply on October 19, 2015 to complete the briefing. Oral argument occurred on Monday, February 29, 2016. In many cases the 5th Circuit Court of Appeals issues its decision several months after oral argument, but there is no set time limit.

In September 2007, BD and MDC Investment Holdings, Inc. (“MDC”) sued the Company in the United States District Court for the Eastern District of Texas, Texarkana Division, initially alleging that the Company is infringing two U.S. patents of MDC (6,179,812 and 7,090,656) that are licensed to BD. BD and MDC seek injunctive relief and unspecified damages. The Company counterclaimed for declarations of non-infringement, invalidity, and unenforceability of the asserted patents. The plaintiffs subsequently dropped allegations with regard to patent no. 7,090,656 and the Company subsequently dropped its counterclaims for unenforceability of the asserted patents. On June 30, 2015, the Court ordered that further proceedings in this matter be stayed and that this case remain administratively closed until resolution of all appeals in the case detailed in the first paragraph of this Note 8.

Options for the purchase of 2,899,108 shares of Common Stock have been issued under the 2008 Stock Option Plan, which, pursuant to a 2014 amendment, authorizes a total of 6,000,000 shares of Common Stock upon the exercise of stock options.

Options for the purchase of 1,000,000 shares of Common Stock remain outstanding under an option granted to Mr. Thomas J. Shaw.

The Compensation and Benefits Committee administers all plans and determines and/or recommends to the Board exercise prices at which options are granted. All executive compensation, including the granting of stock options, is determined by the Compensation and Benefits Committee. Shares issued upon exercise of options come from the Company’s authorized but unissued Common Stock. The options vested over periods up to three years from the date of grant and generally expire ten years after the date of grant. Unvested options issued under the 2008 Stock Option Plan expire immediately after termination of employment.

PREFERRED STOCK TRANSACTION	20.PREFERRED STOCK TRANSACTION The Company exchanged 728,000 shares of Common Stock for 200,000 shares of our Series IV Class B Convertible Preferred Stock as of November 30, 2015 pursuant to an agreement with a shareholder. Such shareholder agreed to waive all unpaid dividends in arrears associated with the tendered preferred stock, equaling $3,094,795. The fair value of the common stock issued ($2,606,240) over the carrying value of the preferred stock extinguished ($2,000,000) was $606,240. The excess of the dividend arrearage waived less the excess value of common stock issued, less the preferred dividend requirements for 2015 through the extinguishment date ($182,877) resulted in a deemed capital contribution of $2,305,678 for purposes of computing net income available to common shareholders. Future dividend requirements of $200,000 per year are avoided as a result of this transaction.
