Revenues are recognized when control of these services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The Company determines revenue recognition through the following steps: ● Identification of the contract, or contracts, 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 subscription fee under most contracts is variable based on the value of the advertising spend that the Company’s advertisers manage through the Company’s platform and is generally invoiced and recognized on a monthly basis. Contracts with direct advertisers and certain contracts with independent advertising agencies also include a minimum monthly fee that is recognized over the duration of the contract, commencing on the date that the Company’s platform is made available to the customer. Due to the nature of the platform and the services performed under the subscription agreements, the Company determined that the variable and fixed subscription fees should be allocated to the monthly period in which the Company has the contractual right to bill under the contract.
