37 New 606 Accounting Standard Global Principles-based 5 Step Model Step 1 Identify the contract with the customer Step 2 Identify the separate performance obligations in the contract Step 3 Determine the transaction price Step 4 Allocate transaction price to the separate performance obligations Step 5 Recognize revenue when (or as) the entity satisfies the performance obligation

38 ASC 606: What Changes Most appliances and software, along with related subscription and support contracts, are determined to provide a single security solution and therefore one performance obligation Most appliances deemed to have value beyond initial contract term Four-year economic life based on historical purchase patterns Revenue from appliances that rely on dynamic threat intelligence updates will be recognized over longer of the economic life (4 years) or the contract term. Exceptions are PX network forensics and CMS Management appliances. Term licenses that do not rely on dynamic threat intelligence updates will be recognized upfront. Revenue from subscriptions and support contracts will be recognized over the contract term. Supplemental data on the mix of billings and revenue will be organized into three categories to avoid separation of performance obligations. Higher % of billings will be recognized ratably; deferred revenue, deferred costs of goods sold, and deferred operating expenses (sales commissions) increase. Cost of sales for most appliances will be deferred and amortized over same period as the related revenue Sales commissions will be capitalized and amortized, typically over 3-4 years for new business or the contract term for renewals.

39 ASC 606: What Does Not change Revenue from subscriptions (both attached and standalone) cloud and managed service subscriptions and maintenance contracts continues to be recognized ratably over contract term Revenue from professional services continues to be recognized as delivered Total billings Although the timing of some billings may change due to different treatment of early renewals under 605 and 606, total billings do not change Operating Cash Flow

40 Recognition of Revenue and Costs Product ASC 605 ASC 606 Upfront Primarily ratable 1 (4 year useful life) Product subscriptions Ratable No change Support and Maintenance Ratable No change Professional Services As delivered No change Product COGS Upfront Primarily ratable 1 Subscription COGS Ratable No change Professional Services COGS As incurred No change Commissions Expensed upon booking Capitalized and amortized ratably 1. Revenue and product COGS related to all appliances that rely on DTI updates will be recognized ratably. Revenue and COGS from PX network forensics appliances, CMS management appliances, tech fees and FireEye Security Orchestrator (FSO) term licenses are recognized up front; in combination, these product lines have historically contributed approximately 20% of total product billings and revenue but less than 5% of total billings.
