(j) Revenue Recognition Revenue consists of fees earned from the temporary and permanent placement of healthcare professionals and executives as well as from the Company’s software-as-a-service (SaaS)-based technologies, including its vendor management systems (VMS) and its scheduling software. Revenue from temporary staffing services is recognized as the services are rendered by the healthcare professional. Under the Company’s managed services program arrangements, the Company manages all or a part of a customer’s supplemental workforce needs utilizing its own pool of healthcare professionals along with those of third-party subcontractors, and revenue and the related direct costs are recorded in accordance with the accounting guidance on reporting revenue gross as a principal versus net as an agent. When the Company uses subcontractors and acts as an agent, revenue is recorded net of the related subcontractor’s expense. Revenue from recruitment and permanent placement services is recognized as the services are provided and upon successful placements. The Company’s SaaS-based revenue is recognized ratably over the applicable arrangement’s service period. Fees billed in advance of being earned are recorded as deferred revenue.

See Note (4), “Fair Value Measurement,” for additional information. (m) Income Taxes The Company records income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period the changes are enacted. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income, and tax-planning strategies in making this assessment. The Company recognizes the effect of income tax positions only if it is more likely than not that such positions will be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in
