Unsecured Revolving Credit Facility

We have a $700,000 unsecured revolving credit facility ('Credit Facility'). The Credit Facility includes a committed letter of credit subfacility of $55,000. The commitments under the Credit Facility will expire (and any borrowings outstanding under the Credit Facility will become due and payable) on March 1, 2018. In the next twelve months, we have the ability and intent to repay a portion of the outstanding line of credit obligations using cash; therefore, we have classified this portion of the line of credit as a current liability. The Credit Facility contains certain financial and other covenants, and our right to borrow under the Credit Facility is conditioned upon, among other things, our compliance with these covenants. We are currently in compliance with these covenants.

Borrowings under the Credit Facility generally bear interest at a rate per annum equal to the London Interbank Offered Rate ('LIBOR') for interest periods of various lengths selected by us, plus 0.95%. A change in LIBOR impacts the interest rate on our borrowings, which in turn impacts interest expense incurred and cash flows. Based on the interest periods we have chosen, our weighted per annum interest rate at June 30, 2016 was approximately 1.4%. We pay a commitment fee for the unused portion of the Credit Facility. This fee is either 0.10% or 0.125% per annum based on our usage of the Credit Facility.

Note Payable

On December 7, 2015, we signed an agreement to acquire, effective January 2, 2017, certain assets related to the collection and management of certain portions of our business and financial data from Apex Industrial Technologies, LLC ('Apex'), a provider of automated point-of-use dispensing and supply chain technologies. The agreement includes a transition arrangement which requires us to assume responsibility for certain software that is licensed by Apex assuming that hosting services are transitioned from Apex to us. The total consideration for the assets and transition arrangement is $27,000, of which $12,000 was paid in cash in December 2015 to cover costs associated with decoupling systems and programs, transition planning expenses, completing system enhancements, and engaging in training to effectively and efficiently transfer hosting activities to us. The remaining $15,000 covers equipment costs and post transfer expenses related to the transition, and is payable in installments pursuant to an unsecured note, with the final payment due in December 2017. Payment of the $15,000 is dependent upon the transfer of hosting activities to us. We reserve the right to terminate the transition of hosting services from Apex to us and, if we decide to exercise that option, then we will not be required to make the $15,000 in payments and Apex will continue to provide us with fee-based hosting services. The note bears interest at an annual rate of 0.56%. Interest on the unpaid principal balance of the note is due and payable on the last day of each calendar quarter.

Legal Contingencies

The nature of our potential exposure to legal contingencies is described in our 2015 annual report on Form 10-K in Note 9 of the Notes to Consolidated Financial Statements. As of June 30, 2016, there were no litigation matters that we consider to be probable or reasonably possible to have a material adverse outcome.
