Revenue by Service Line

Contract Balances

During the three months ended March 31, 2020, the Company recognized capital equipment-related service revenue of approximately $121,000, which was previously included in deferred revenue in the accompanying condensed consolidated balance sheet at December 31, 2019.

In September 2019, the Company entered into a Development Services Agreement with a customer under which the Company was entitled to bill the customer for an upfront payment of $127,600, of which $83,000 and $102,000 are included in deferred revenue in the accompanying March 31, 2020 and December 31, 2019 condensed consolidated balance sheets, respectively.

Also, in September 2019, the Company entered into a Letter of Intent, followed by a related Statement of Work (together with the Letter of Intent, the “Project Documents”) in November 2019, with a customer which is a stockholder and whose Chief Operating Officer is a member of the Company’s Board of Directors, to commence a product development project. Under the terms of the Project Documents, the Company was entitled to bill the customer for: (a) an upfront, nonrefundable payment of $500,000; and (b) quarterly service fees of $500,000 commencing in the fourth quarter of 2019. In February 2020, the Company entered into a Supply Agreement and a Statement of Work (the “European SOW”) with a European affiliate of the customer. Under the terms of the European SOW, the Company was entitled to bill the customer on a quarterly basis, commencing in the first quarter of 2020, for service fees of $250,000. The Company recognizes as revenue each of the upfront payments described in this paragraph in proportional relationship to the transaction prices of the performance obligations contained in the related agreements, and recognizes as revenue the quarterly service fees described in this paragraph as stand-by services beginning in the quarter such services commenced. Based on the foregoing, approximately $464,000 and $625,000 of the aggregate amount of all the payments described in this paragraph were included in deferred revenue in the accompanying condensed consolidated balance sheets at March 31, 2020 and December 31, 2019, respectively.

The Company offers an upgraded version of its software at no additional charge to customers purchasing a three-year systems service agreement. The transaction prices of the software and the service agreement are determined through an allocation of the service agreement price based on the standalone prices of the software and the service agreements. The transaction price of the software is recognized as revenue upon its installation and comprised approximately $149,000 and $172,000 of unbilled accounts receivable at March 31, 2020 and December 31, 2019, respectively.

Remaining Performance Obligations

The Company’s contracts with customers, other than capital equipment-related service agreements discussed below, are predominantly of terms less than one year. Accordingly, the transaction price of remaining performance obligations related to such contracts at March 31, 2020 are not material.

Revenue with respect to remaining performance obligations related to capital equipment-related service agreements with original terms in excess of one year and the upfront payments discussed under the heading “Contract Balances” above amounted to approximately $992,000 at March 31, 2020. The Company expects to recognize this revenue within the next three years.
