Subsequent Event	Note 10. Subsequent Event As discussed in Note 6, the Company entered into the SVB Loan Agreement with SVB and terminated the previous Loan Agreement with The PrivateBank by paying off the outstanding term loan. The terms of the SVB Loan Agreement provide for a $5 million line of credit with a $3 million Export-Import (EX-IM) sublimit at an interest rate that ranges from prime plus 50 basis points on up to prime plus 375 basis points depending on the Company’s liquidity ratio and adjusted six month rolling EBITDA as defined in the agreement. The SVB Loan Agreement contains a covenant for an initial minimum six month rolling adjusted EBITDA of negative $1,250,000 which reduces over time to $1 as of April, 2013. There is also a minimum liquidity ratio of 2.25 based on outstanding cash, receivables and debt as defined in the agreement. Using the financial condition of the Company as of December 30, 2011 and the related historical EBITDA, the Company would pay an interest rate of prime plus 50 basis points on the SVB Loan Agreement line of credit, the same rate as it previously incurred under The PrivateBank Loan Agreement. The amount that can be drawn on the line of credit is subject to a formula based on the outstanding receivables and inventory of the Company. In addition, the SVB Loan Agreement provides for a $1 million term loan with principal payable over three years in equal installments and interest at a rate ranging from prime plus 100 basis points to prime plus 425 basis points dependent on the Company’s liquidity ratio and adjusted six month rolling EBITDA as defined in the SVB Loan Agreement. The EX-IM line of credit with SVB is guaranteed by API and Picometrix, and all borrowings under the SVB Loan Agreement are secured by first priority security interest that each of API and Picometrix granted to SVB over substantially all their respective assets. The Company was in compliance with the related liquidity and adjusted EBITDA covenant with SVB as of the closing. The term of the SVB loan agreement is two years and can be renewed annually by mutual consent. Pursuant to the terms of the SVB Loan Agreement, on January 31, 2012, $728,735 of the proceeds of the term loan were used to repay all indebtedness owed to the Note Holders under the Picometrix Notes, which were initially issued on May 2, 2005 in the aggregate principal amount of $2,900,500 and scheduled to mature on September 1, 2012. Interest on the Picometrix Notes accrued at a rate of Prime (as defined in the Picometrix Notes) plus 2.0%, and the Company was required to pay interest quarterly through the maturity date. The Company was permitted to prepay the outstanding indebtedness under the PrivateBank Loan Agreement and Picometrix Notes without penalty.
