Unsecured Revolving Credit Facility

We have a $700,000 committed 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 loans using cash; therefore, we have classified this portion 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%. Based on the interest periods we have chosen, our weighted per annum interest rate at December 31, 2016 was approximately 1.7%. 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.

Senior Unsecured Promissory Notes Payable

On July 20, 2016 (the 'Effective Date'), we entered into a master note agreement (the 'Master Note Agreement') with certain institutional lenders, pursuant to which, during the period commencing on the Effective Date and ending three years thereafter, we may issue at our discretion in private placements, and the institutional lenders may purchase at their discretion, senior unsecured promissory notes of the Company (the 'Notes') in the aggregate principal amount outstanding from time to time of up to $200,000. The Notes will bear interest at either a fixed rate, or a floating rate based on LIBOR for an interest period of one, three, or six months. The Notes will mature no later than 12 years after the date of issuance thereof, in the case of fixed rate Notes, or 10 years after the date of issuance thereof, in the case of floating rate Notes. All of the Notes will be prepayable at our option in whole or in part. The Master Note Agreement contains certain financial and other covenants. We are currently in compliance with these covenants.

Two series of unsecured senior Notes are currently outstanding under the Master Note Agreement, each of which was issued on the Effective Date. The first series of Notes ('Series A') is in an aggregate principal amount of $40,000, is due and payable in full on July 20, 2021, and bears interest at a fixed rate of 2.00% per annum. The second series of Notes ('Series B') is in an aggregate principal amount of $35,000, is due and payable in full on July 20, 2022, and bears interest at a fixed rate of 2.45% per annum. There is no amortization of the Series A and Series B Notes prior to their maturity dates. Interest on such Notes is payable quarterly in arrears on January 20, April 20, July 20, and October 20 of each year, beginning on October 20, 2016. The carrying value of our Series A and Series B Notes approximates fair value. The fair value was based on available external pricing data and current market rates for similar debt instruments, among other factors, which are classified as level 2 inputs within the fair value hierarchy.

Note Payable Under Asset Purchase Agreement

On December 7, 2015, we signed an agreement to purchase, effective January 2, 2017 ('Asset Purchase Effective Date'), 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. The total consideration for the assets is $27,000, of which $12,000 was paid in cash in December 2015 in advance of the Asset Purchase Effective Date. The remaining $15,000 is payable in installments pursuant to an unsecured note. The first $5,000 installment was paid in December 2016, while the two remaining installments of $5,000 each will be paid in June 2017 and December 2017. 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. In 2015, the $15,000 note represented a non-cash investing and financing activity in our Consolidated Statements of Cash Flows, while the payments made in 2016 and 2015 are included in our Consolidated Statements of Cash Flows as net cash used in investing activities in 'Other'.

Legal Contingencies

We are involved in certain legal actions. The outcomes of these legal actions are not within our complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, that could require significant expenditures or result in lost revenues. We record a liability for these legal actions when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded. As of December 31, 2016, there were no litigation matters that we consider to be probable or reasonably possible to have a material adverse outcome.
