The fair value of developed technology was estimated using the reproduction cost method (Level 3), which utilized assumptions for the cost to replace, such as the workforce, timing and resources required, as well as a theoretical profit margin and opportunity cost. Customer relationships represent the fair value of projected subscription revenue that is expected to be generated from existing customers of Realm as of the Acquisition Date.

These two intangible assets acquired are being amortized over their estimated useful lives using the straight-line method of amortization, which approximates the distribution of the economic value of the identified intangible assets. See Note 5, Goodwill and Acquired Intangible Assets, Net , for further details Deferred revenue was estimated at fair value under the cost build-up method (Level 3), which was determined based on estimated direct and indirect costs to support and fulfill the subscription obligation plus an assumed operating margin. Deferred revenue will be recognized based on the revenue criteria set forth in Note 2, Summary of Significant Accounting Policies , in the Companys 2019 Form 10-K.
