REVENUE

Disaggregated Revenue

Based on similar operational and economic characteristics, the Company’s revenue from contracts with customers is disaggregated by License and transaction fees and Equipment sales, as reported in the Company’s Condensed Consolidated Statements of Operations. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are influenced by economic factors, and also represent the level at which management makes operating decisions and assesses financial performance.

Transaction Price Allocated to Future Performance Obligations

In determining the transaction price allocated to unsatisfied performance obligations, we did not include non-recurring charges. Further, we applied the practical expedient to not consider arrangements with an original expected duration of one year or less, which are primarily month to month rental agreements. The majority of contracts are considered to have a contractual term of between 36 and 60 months based on implied and explicit termination penalties. These amounts will be converted into revenue in future periods as work is performed, primarily based on the services provided or at delivery and acceptance of products, depending on the applicable accounting method.

The following table reflects the estimated fees to be recognized in the future related to performance obligations that are unsatisfied at the end of the period:



($ in thousands)	As of December 31, 2019

2020	$	6,884
2021	12,169
2022	10,611
2023	7,977
2024 and thereafter	4,250
Total	$	41,891

Contract Liabilities

The Company’s contract liability (i.e., deferred revenue) balances are as follows:



	Three months ended December 31,	Six months ended December 31,
($ in thousands)	2019	2019

Deferred revenue, beginning of the period	1,649	1,681
Deferred revenue, end of the period	1,629	1,629
Revenue recognized in the period from amounts included in deferred revenue at the beginning of the period	209	360

The change in the contract liabilities period-over-period is primarily the result of timing difference between the Company’s satisfaction of a performance obligation and payment from the customer.

Contract Costs

At December 31, 2019, the Company had net capitalized costs to obtain contracts of $0.3 million included in Prepaid expenses and other current assets and $1.7 million included in Other noncurrent assets on the Condensed Consolidated Balance Sheet. None of these capitalized contract costs were impaired. During the three and six months ended December 31, 2019, amortization of capitalized contract costs was $0.1 million and $0.2 million, respectively.
