This Investopedia article by Will Kenton, “Employee Stock Purchase Plan (ESPP): What It Is and How It Works,” is included because it clearly explains the mechanics (payroll deductions, offering/purchase dates, look-back and discount provisions), distinctions between qualified and non-qualified plans, contribution limits and the often-complex tax and holding‑period implications—practical detail that belongs in Chapter “Our Financial Vehicles in Action,” Part 3: Capital in Action, as a concise, reader-friendly reference on employer‑provided investment vehicles that helps readers evaluate ESPPs as a purposeful way to deploy personal capital and understand their potential financial and tax outcomes.
