Debt	3 Months Ended
Sep. 30, 2012
Debt	D. Debt On December 16, 2010, we executed a new Credit Agreement with Wells Fargo Bank, N.A.. This Credit Agreement replaced our previous credit facility and provides us with a line of credit of up to $5.0 million. The line of credit may be used to finance working capital requirements. In consideration for granting the line of credit, we paid a commitment fee of $12,500 upon execution of the agreement and paid an additional commitment fee of $12,500 in December 2011. There are no amounts currently drawn under the line of credit and the credit agreement expires on November 1, 2013. Under the terms of the Credit Agreement, borrowings are subject to eligibility requirements including maintaining (i) net income after taxes of not less than $750,000 on a trailing four quarter basis as of the end of each calendar quarter beginning with the four quarter period ended December 31, 2010; and (ii) a ratio of total liabilities to tangible net worth of not greater than 1.25 to 1.0 at any time. Any amounts outstanding under the line of credit will bear interest at a fixed or fluctuating interest rate as elected by NAI from time to time; provided, however, that if the outstanding principal amount is less than $100,000 such amount shall bear interest at the then applicable fluctuating rate of interest. If elected, the fluctuating rate per annum would be equal to 2.75% above the daily one month LIBOR rate as in effect from time to time. If a fixed rate is elected, it would equal a per annum rate of 2.50% above the LIBOR rate in effect on the first day of the applicable fixed rate term. Any amounts outstanding under the line of credit must be paid in full on or before November 1, 2013; provided, however, that we must maintain a zero balance on advances under the line of credit for a period of at least 30 consecutive days during each fiscal year. Amounts outstanding that are subject to a fluctuating interest rate may be prepaid at any time without penalty. Amounts outstanding that are subject to a fixed interest rate may be prepaid at any time in minimum amounts of $100,000, subject to a prepayment fee equal to the sum of the discounted monthly differences for each month from the month of prepayment through the month in which the then applicable fixed rate term matures. Our obligations under the Credit Agreement are secured by our accounts receivable and other rights to payment, general intangibles, inventory, equipment and fixtures. We also have a foreign exchange facility with Wells Fargo in effect until November 1, 2013, and with Bank of America, N.A. in effect until March 15, 2013. On September 30, 2012, we were in compliance with all of the financial and other covenants required under the Credit Agreement. On September 22, 2006, NAIE, our wholly owned subsidiary, entered into a credit facility to provide it with a credit line of up to CHF 1.3 million, or approximately $1.4 million, which was the initial maximum aggregate amount that could be outstanding at any one time under the credit facility. This maximum amount is reduced annually by CHF 160,000, or approximately $170,000. On February 19, 2007, NAIE amended its credit facility to provide that the maximum aggregate amount that may be outstanding under the facility cannot be reduced below CHF 500,000, or approximately $532,000. As of September 30, 2012, there was no outstanding balance under this credit facility. Under its credit facility, NAIE may draw amounts either as current account loan credits to its current or future bank accounts or as fixed loans with a maximum term of 24 months. Current account loans will bear interest at the rate of 5% per annum. Fixed loans will bear interest at a rate determined by the parties based on current market conditions and must be repaid pursuant to a repayment schedule established by the parties at the time of the loan. If a fixed loan is repaid early at NAIE’s election or in connection with the termination of the credit facility, NAIE will be charged a pre-payment penalty equal to 0.1% of the principal amount of the fixed loan or CHF 1,000 (approximately $1,064), whichever is greater. The bank reserves the right to refuse individual requests for an advance under the credit facility, although its exercise of such right will not have the effect of terminating the credit facility as a whole. We did not use our working capital line of credit nor did we have any long-term debt outstanding during the three months ended September 30, 2012. As of September 30, 2012, we had $5.5 million available under our credit facilities.

On December 16, 2010, we executed a new Credit Agreement with Wells Fargo Bank, N.A.. This Credit Agreement replaced our previous credit facility and provides us with a line of credit of up to $5.0 million. The line of credit may be used to finance working capital requirements.

Any amounts outstanding under the line of credit will bear interest at a fixed or fluctuating interest rate as elected by NAI from time to time; provided, however, that if the outstanding principal amount is less than $100,000 such amount shall bear interest at the then applicable fluctuating rate of interest. If elected, the fluctuating rate per annum would be equal to 2.75% above the daily one month LIBOR rate as in effect from time to time. If a fixed rate is elected, it would equal a per annum rate of 2.50% above the LIBOR rate in effect on the first day of the applicable fixed rate term. Any amounts outstanding under the line of credit must be paid in full on or before November 1, 2013; provided, however, that we must maintain a zero balance on advances under the line of credit for a period of at least 30 consecutive days during each fiscal year. Amounts outstanding that are subject to a fluctuating interest rate may be prepaid at any time without penalty. Amounts outstanding that are subject to a fixed interest rate may be prepaid at any time in minimum amounts of $100,000, subject to a prepayment fee equal to the sum of the discounted monthly differences for each month from the month of prepayment through the month in which the then applicable fixed rate term matures.

Our obligations under the Credit Agreement are secured by our accounts receivable and other rights to payment, general intangibles, inventory, equipment and fixtures.
