Financial Statement Presentation

The condensed consolidated balance sheets and condensed consolidated statement of changes in stockholders’ equity as of September 30, 2016 and the related condensed consolidated statements of (loss) income and comprehensive (loss) income, and the condensed consolidated statements of cash flows for the periods ended September 30, 2016 and 2015 have been prepared by Company management. In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at September 30, 2016 and 2015 and for the periods then ended have been made.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2015 Annual Report to Shareholders on Form 10-K. The results of operations for the period ended September 30, 2016 are not necessarily indicative of operating results for the entire year.

The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates.

Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.

	Foreign Currency Translation		Unrealized (loss)/gain on securities		Pension liability adjustment		Accumulated Other Comprehensive Loss

The Company tests for other-than-temporary losses on a quarterly basis and has considered the unrealized losses shown above to be temporary in nature. The Company intends to hold these investments until it can recover the full principal amount and has the ability to do so based on its other sources of liquidity. The Company expects these recoveries to occur prior to the contractual maturities. All unrealized losses as of September 30, 2016 were in a continuous unrealized loss position for less than twelve months and are not deemed to be other than temporarily impaired as of September 30, 2016.

The following table summarizes the estimated fair value of our investments, designated as available-for-sale and classified by the contractual maturity date of the securities as of September 30, 2016:



	Amortized Cost		Estimated Market Value

Due within one year	$	8,810,000	$	8,816,000
Due after one year through five years		725,000		728,000
	$	9,535,000	$	9,544,000

The Company did not recognize any gross realized gains, and gross realized losses were immaterial, during the three-month periods ending September 30, 2016 and 2015, respectively. If the Company had realized gains or losses, they would be included within investment and other income in the accompanying consolidated results of operations.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

NOTE 3 - STOCK-BASED COMPENSATION

Employee Stock Purchase Plan

Under the Company’s Employee Stock Purchase Plan (“ESPP”), employees are able to acquire shares of common stock at 85% of the price at the end of each current quarterly plan term. The most recent term ended September 30, 2016. The ESPP is considered compensatory under current Internal Revenue Service rules. At September 30, 2016, after giving effect to the shares issued as of that date, 85,569 shares remain available for purchase under the ESPP.

2011 Executive Incentive Compensation Plan

On March 28, 2011 the Board adopted and on May 19, 2011 the Company’s shareholders approved the Company’s 2011 Executive Incentive Compensation Plan (“2011 Incentive Plan”). The 2011 Incentive Plan authorizes incentive awards to officers, key employees and non-employee directors in the form of options (incentive and non-qualified), stock appreciation rights, restricted stock, restricted stock units, performance stock units (“deferred stock”), performance cash units, and other awards in stock, cash, or a combination of stock and cash. The 2011 Incentive Plan, as amended, allows the issuance of up to 2,000,000 shares of common stock.

During 2016, stock options covering 325,968 shares have been awarded to key executive employees and directors. These options expire seven years from the date of award and vest 25% each year beginning one year after the date of award. The Company also granted deferred stock awards of 102,161 shares to key employees during the first quarter of 2016 under the Company’s long-term incentive plan for performance over the 2016 to 2018 period. The actual number of shares of deferred stock, if any, that are ultimately earned by the respective employees will be determined based on achievement against performance goals at the end of the three year period ending December 31, 2018 and any shares earned will be issued in the first quarter of 2019 to those key employees still with the Company at that time.

At September 30, 2016, 131,035 shares have been issued under the 2011 Incentive Plan, 1,121,153 shares are subject to currently outstanding options, deferred stock awards, and unvested restricted stock units, and 747,812 shares are eligible for grant under future awards.

Stock Option Plan for Directors

Shares of common stock are reserved for issuance to non-employee directors under options granted by the Company prior to 2011 under its Stock Option Plan for Non-Employee Directors (the “Director Plan”). Under the Director Plan nonqualified stock options to acquire shares of common stock were automatically granted to each non-employee director concurrent with annual meetings of shareholders in 2010 and earlier years, with the exercise price of options granted being the fair market value of the common stock on the date of the respective shareholder meetings. Options granted under the Director Plan expire 10 years from date of grant. No options were granted under the Director Plan in 2014 or 2015. The Company amended the Director Plan in May 2011 to prohibit future option grants. As of September 30, 2016, there were 63,000 shares subject to outstanding options under the Director Plan.

1992 Stock Plan

Under the Company’s 1992 Stock Plan (“the Stock Plan”), shares of common stock may be issued pursuant to stock options, restricted stock or deferred stock grants to officers and key employees. Exercise prices of stock options under the Stock Plan cannot be less than fair market value of the stock on the date of grant. Rules and conditions governing awards of stock options, restricted stock and deferred stock are determined by the Compensation Committee of the Board of Directors, subject to limitations in the Stock Plan. The Company amended the Stock Plan in 2011 to prohibit future stock options or other equity awards.

At September 30, 2016, after reserving for stock options and deferred stock awards granted in prior years and adjusting for forfeitures and issuances during the year, there were 10,230 shares reserved for issuance under the Stock Plan. The Company has not awarded stock options or deferred stock under the Stock Plan since 2011.
