8. Revenue Recognition

The primary sources of revenue for the Company are as follows: revenue from contracts with customers which includes commissions and fees, principal transactions, and advisory fees as well as other income which includes margin interest, marketing, and distribution fees. The recognition and measurement of revenue is based on the assessment of individual contract terms. The amount of revenue recognized by the Company is based on the consideration specified in contracts with its clients. The Company recognizes revenue when a performance obligation is satisfied over time as the services are performed or at a point in time depending on the nature of the services provided as further detailed below. Significant judgment is required to determine whether performance obligations are satisfied at a point in time or over time; how to allocate transaction prices where multiple performance obligations are identified; when to recognize revenue based on the appropriate measure of the Company’s progress under the contract; and whether constraints on variable consideration should be applied due to uncertain future events. For the three months and six months ended June 30, 2019 and 2018, there were no costs capitalized related to obtaining or fulfilling a contract with a customer, and thus the Company has no balances for contract assets or contract liabilities.
