The Company has performed an analysis of the effects of adopting this guidance. The analysis included the following items: ● identifying what constitutes a contract within the Company’s business practices, ● identifying performance obligations within our contracts, ● determining transaction prices, ● allocating the transaction price to performance obligations, ● determination of when performance obligations are satisfied and revenue is earned, ● disaggregation of revenue by source within segments, and ● principal verses agent considerations.

This analysis consisted of the following items: ● categorize securities as either equity securities or debt securities, ● determine which securities held by the Company have readily determinable fair values, ● determine that the exit price notion will be used when measuring the fair value of financial instruments for disclosure purposes, ● consider the need for a valuation allowance related to a deferred tax asset on available-for-sale securities in combination with the Company’s other deferred tax assets. Based upon this evaluation, the effects of adopting this guidance is not expected to have a significant impact on the Company’s financial condition or cash flows but it is expected to have a significant impact on the Company’s results of operations through the recognition of increases or decreases in market value each reporting period rather than recognizing them through comprehensive income.

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]	3. MARKETABLE EQUITY SECURITIES The Company accounts for its marketable securities in accordance with ASC Topic 320, Investments-Debt and Equity Securities 320 Marketable equity securities classified as available-for-sale are carried at fair value, with the unrealized gains and losses, net of tax, included as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Realized gains and losses, declines in value judged to be other-than-temporary on available-for-sale securities, and increases or decreases in value on trading securities, if any, are included in the determination of net income. A quarterly evaluation is performed in order to judge whether declines in value below cost should be considered temporary and when losses are deemed to be other-than-temporary. Several factors are considered in this evaluation process including the severity and duration of the decline in value, the financial condition and near-term outlook for the specific issuer and the Company’s ability to hold the securities. For the years ended December 31, 2016, 2015 2014, $709,000, $833,000 $1,000, The following table sets forth cost, market value and unrealized gain on equity securities classified as available-for-sale as of December 31, 2016 2015. no December 31, 2016 December 31, 2015. 2016 2015 (in thousands) Available-for-sale securities Fair market value $ 27,621 $ 24,575 Cost 15,569 16,015 Unrealized gain $ 12,052 $ 8,560 The following table sets forth the gross unrealized gains and losses on the Company’s marketable securities that are classified as available-for-sale as of December 31, 2016 2015. 2016 2015 (in thousands) Available-for-sale securities Gross unrealized gains $ 12,161 $ 9,893 Gross unrealized losses 109 1,333 Net unrealized gains $ 12,052 $ 8,560 As of December 31, 2016 2015, $7,476,000 $5,310,000, For the year ended December 31, 2016 $2,166,000, December 31, 2015, $1,092,000, For the years ended December 31, 2016, 2015 2014, $1,024,000, $1,058,000, $896,000 During 2016, no 2015, The following table shows recognized gains (losses) in market value for securities classified as trading during 2015 2014.
