Accounting Policies [Abstract]

Basis of presentation

Basis of presentation:  The financial statements and accompanying notes have been prepared on a consolidated basis and reflect the consolidated financial position of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated from these financial statements. The Company's fiscal year ends on the Saturday closest to December 31, and the Company’s normal fiscal quarters end on the Saturday 13 weeks after the last fiscal year end or fiscal quarter end.  Every fifth or sixth fiscal year, the inclusion of an extra week occurs due to the Company’s floating year-end date.  The fiscal year 2014 will include 53 weeks instead of the normal 52 weeks, and will end on January 3, 2015.

Changes in accounting estimate

Changes in accounting estimate: During the six-month period ended June 28, 2014, the Company evaluated assumptions for estimating the fair value of the Company’s stock options.  The Company uses the Black-Scholes based option valuation model, which requires assumptions on (i) volatility, (ii) expected dividends, (iii) expected term and (iv) risk-free rate.  While evaluating the assumptions on volatility, the Company determined that the historical volatility the Company’s common stock needs to be considered when estimating the expected volatility.  Previously, the Company calculated expected volatility based on publicly held companies in similar industries and did not consider the historical volatility of the Company’s common stock, as the historical measurement period that was available to compute the volatility rate of the Company’s common stock was shorter than the expected life of the options.

For the stock options granted during the six-month period ended June 28, 2014, the Company calculated expected volatility rate based on the combined volatility of publicly held companies in similar industries and volatility of the Company’s common stock.  A 20~25% weight was assigned to the volatility of the Company’s common stock as the historical volatility of the Company’s common stock covers only the period since June 2008 in a thinly traded market.  The weighted average expected volatility for the stock options granted during the six-month period ended June 28, 2014 using this revised calculation method was approximately 73%.  The weighted average expected volatility would have been approximately 30%, if we calculated based on only publicly held companies in similar industries.

Inventories

Inventories:  Inventories are comprised of raw materials, work-in-process and finished goods.  They are stated at the lower of cost, determined by the first-in, first-out method (FIFO) method, or market.  Labor and overhead has been added to inventory that was manufactured or characterized by the Company.  The amounts of major classes of inventory as of June 28, 2014 and December 28, 2013 are as follows:

	June 28, 2014		December 28, 2013
Reference standards	$	1,707,272	$	1,769,160
Bulk ingredients		1,421,756		694,965
		3,129,028		2,464,125
Less valuation allowance		256,000		260,000
	$	2,873,028	$	2,204,125

Recent accounting standards

Recent accounting standards: In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for us in our first quarter of fiscal 2018 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.
