Revenues are recognized when control of the promised goods or services are transferred to the customers in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company determines revenue recognition through the following steps: ● identification of the contract with a customer; ● identification of the performance obligations in the contract; ● determination of the transaction price; ● allocation of the transaction price to the performance obligations in the contract; and ● recognition of revenue when, or as, the Company satisfies a performance obligation. The Company enters into contracts that can include various combinations of products and services, as detailed below, which are generally capable of being distinct and accounted for as separate performance obligations.

Standalone selling prices of services are typically estimated based on observable transactions when these services are sold on a standalone basis.

Royalties are calculated either as a percentage of the revenues received by the Company’s licensees on sales of products incorporating the Company’s IP or on a per unit basis, as specified in the agreements with the licensees. For a majority of the Company’s royalty revenues, the Company receives the actual sales data from its customers after the quarter ends and accounts for it as unbilled receivables.

The fair value of each RSU and PSU is the market value as determined by the closing price of the common stock on the day of grant.

Revenue from Contract with Customer [Policy Text Block]	Revenue recognition : Effective as of January 1, 2018, 606, Revenue from Contracts with Customers 606” 2 The following is a description of principal activities from which the Company generates revenue. Revenues are recognized when control of the promised goods or services are transferred to the customers in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company determines revenue recognition through the following steps: ● identification of the contract with a customer; ● identification of the performance obligations in the contract; ● determination of the transaction price; ● allocation of the transaction price to the performance obligations in the contract; and ● recognition of revenue when, or as, the Company satisfies a performance obligation. The Company enters into contracts that can include various combinations of products and services, as detailed below, which are generally capable of being distinct and accounted for as separate performance obligations. The Company generates its revenues from ( 1 2 3 The Company accounts for its IP license revenues and related services, which provide the Company's customers with rights to use the Company's IP, in accordance with ASC 606. may 606, Most of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately, if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. Standalone selling prices of IP license are typically estimated using the residual approach. Standalone selling prices of services are typically estimated based on observable transactions when these services are sold on a standalone basis. When contracts involve a significant financing component, the Company adjusts the promised amount of consideration for the effects of the time value of money if the timing of payments agreed to by the parties to the contract (either explicitly or implicitly) provide the customer with a significant benefit of financing, unless the financing period is under one 606. Revenues from contracts that involve significant customization of the Company’s IP to customer-specific specifications are performance obligations the Company generally accounts for as performance obligations satisfied over time. The Company’s performance does not first Revenues that are derived from the sale of a licensee’s products that incorporate the Company’s IP are classified as royalty revenues. Royalty revenues are recognized during the quarter in which the sale of the product incorporating the Company’s IP occurs. Royalties are calculated either as a percentage of the revenues received by the Company’s licensees on sales of products incorporating the Company’s IP or on a per unit basis, as specified in the agreements with the licensees. For a majority of the Company’s royalty revenues, the Company receives the actual sales data from its customers after the quarter ends and accounts for it as unbilled receivables. When the Company does not In addition to license fees, contracts with customers generally contain an agreement to provide for training and post contract support, which consists of telephone or e-mail support, correction of errors (bug fixing) and unspecified updates and upgrades.

In addition, the Company participated in programs sponsored by the Hong Kong government for the support of the above acquisition, and as a result, the Company received during 2019 an amount of $239 related to the NB-IoT technologies, which was reduced from the gross carrying amount of intangible assets. The Company recorded the amortization cost of the NB-IoT technologies in "cost of revenues" on the Company’s interim condensed consolidated statements of income (loss).
