8.	Guarantees and Other Obligations

Product Warranty

Our products are generally sold with warranty periods that range from

months following sale or acceptance. The product warranty promises customers that delivered products are as specified in the contract (an “assurance-type warranty”). Therefore, we account for such product warranties under ASC

460,

and

not

as a separate performance obligation. Parts and labor are covered under the terms of the warranty agreement. The warranty provision is based on historical and projected experience by product and configuration.

Changes in accrued warranty were as follows (

Borrowings

Revolving Lines of Credit

We have credit agreements with multiple financial institutions in Japan under which they administer lines of credit on behalf of our wholly owned Kita subsidiary. The credit facilities renew monthly and provide Kita with access to working capital totaling up to

$6.3

million and at

June 30, 2018,

total borrowings outstanding under the revolving lines of credit were

$3.2

million. As these credit facility agreements renew monthly, they have been included in short-term borrowings in our condensed consolidated balance sheet. The revolving lines of credit are denominated in Japanese Yen and, as a result, amounts disclosed herein will fluctuate because of changes in currency exchange rates.

Term Loans

We have long-term term loans from a series of Japanese financial institutions related to the expansion of Kita’s facility in Osaka, Japan. The loans are collateralized by the facility and land, carry interest rates ranging from

0.05%

0.45%,

and expire at various dates through

2034.

June 30, 2018

the aggregate amount outstanding was

$5.3

million and

$1.2

million of the term loans have been included in current installments of long-term debt in our condensed consolidated balance sheet. The fair value of our debt approximates the carrying value at

June 30, 2018.

The term loans are denominated in Japanese Yen and, as a result, amounts disclosed herein will fluctuate because of changes in currency exchange rates.
