Note 2 – Revenue Recognition

On January 1, 2018, The Company adopted ASC 606, Revenue from Contracts with Customers and all the related amendments and applied it to all contracts that were not completed as of January 1, 2018 using the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of accumulated deficit. Prior period amounts have not been restated and continue to be reported under the accounting standards in effect for those periods.

The Company’s adoption impact related to the recognition of certain previously deferred distributor revenue. The Company does not expect a material impact to its consolidated statements of operations on an ongoing basis from the adoption of the new standard.

The cumulative effect to the Company’s consolidated January 1, 2018 balance sheet from the adoption of the new revenue standard was as follows (in thousands):



Balance Sheet	Balance at December 31, 2017			Adjustments Due to ASC 606			Balance at January 1, 2018
Assets:
Trade and other accounts receivable, net of allowance	$	31,643		$	227		$	31,870
Inventories	32,228			(430		)	31,798
Liabilities and Stockholders’ Equity:
Accounts payable and accrued liabilities	32,758			37			32,795
Deferred revenue and customer deposits	6,669			(518		)	6,151
Accumulated deficit	(247,233		)	278			(246,955		)

The impact of adoption on the Company’s consolidated balance sheet as of March 31, 2018 and consolidated statement of operations for the three months ended March 31, 2018 was not material.

The Company’s revenues primarily result from the sale of manufactured products and reflect the consideration to which the Company expects to be entitled. The Company records revenue based on a five-step model in accordance with ASC 606. For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer.

For product sales, each purchase order represents a contract with a customer and each product sold to a customer typically represents a distinct performance obligation. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales are subject to ExWorks (as defined in Incoterms 2010) delivery terms and revenue is recorded at the point in time when products are picked up by the customer's freight forwarder, as the Company has determined that this is the point in time that control transfers to the customer. Certain customers have shipping terms where control does not transfer until the product is delivered to the customer’s location. For these transactions, revenue is recognized at the time that the product is delivered to the customer’s location.

Provisions for customer volume discounts, product returns, rebates and allowances are variable consideration and are estimated and recorded as a reduction of revenue in the same period the related product revenue is recorded. Such provisions are calculated using historical averages and adjusted for any expected changes due to current business conditions.

The Company provides assurance-type warranties on all product sales for terms ranging from one to eight years. The Company accrues for the estimated warranty costs at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure.

The Company records revenue net of sales tax, value added tax, excise tax and other taxes collected concurrent with revenue-producing activities. The Company has elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized.

The Company’s contracts with customers do not typically include extended payment terms. Payment terms vary by contract type and type of customer and generally range from 30 to 90 days from delivery.

A portion of the Company’s revenue is derived from sales to distributors which represented approximately 8% of revenue for the three months ended March 31, 2018.

Less than five percent of total revenue is derived from non-product sales. When the Company’s contracts with customers require specialized services or other deliverables that are not separately identifiable from other promises in the contracts and, therefore, not distinct, then the non-distinct obligations are accounted for as a single performance obligation. For performance obligations that the Company satisfies over time, revenue is recognized by consistently applying a method of measuring progress toward complete satisfaction of that performance obligation. The Company uses the input method to recognize revenue on the basis of the Company’s efforts or inputs to the satisfaction of a performance obligation relative to the total inputs expected to satisfy that performance obligation. The Company uses the actual costs incurred relative to the total estimated costs to determine its progress towards contract completion.

The following tables disaggregate the Company’s revenue by product line and by shipment destination:



	Three Months Ended March 31,
Product Line:	2018
Energy Storage (formerly Ultracapacitors)	$	23,002
High-Voltage Capacitors	5,414
Total	$	28,416



	Three Months Ended March 31,
Region:	2018
Americas	$	5,818
Asia Pacific	9,827
Europe	12,771
Total	$	28,416

The Company does not have material contract assets since revenue is recognized as control of goods are transferred or as services are performed. As of March 31, 2018 and December 31, 2017, the Company’s contract liabilities primarily relate to cash received under a licensing and services agreement, amounts received in advance from a customer in connection with a specialized services contract for which revenue is recognized over time, and customer advances. Changes in the Company’s contract liabilities, which are included in “deferred revenue and customer deposits” in the Company’s condensed consolidated balance sheets, are as follows:



	Three Months Ended March 31,
	2018
Beginning balance as of December 31, 2017	$	5,331
Impact of adoption of ASC 606	(518		)
Increases due to cash received from customers	1,600
Decreases due to recognition of revenue	(1,624		)
Other changes	(99		)
Contract liabilities as of March 31, 2018	$	4,690

The Company has two uncompleted, non-product sale contracts with original durations of greater than one year. The transaction price allocated to performance obligations unsatisfied at March 31, 2018 in connection with these contracts is $9.5 million. Of this amount, $3.4 million relates to a specialized services contract which is recognized over time and is expected to be completed within one year. The other $6.1 million relates to a licensing and services contract of which $5.2 million relates to the licensing arrangement with revenue to be recognized at a point in time when certain conditions are met which are dependent on the customer, and therefore the timing of recognition cannot currently be estimated, and $0.9 million relates to services which are recognized over time as the services are provided. The licensing and services arrangement also provides for royalties for product sales that use the licensed intellectual property, which will be recognized at the time the related sales occur.
