If I own x% of company A, and A buys company B, do I own x% of B?
Ok, so imagine I own x% of Facebook and Facebook buys WhatsApp, does   this mean I own x% of WhatsApp? Yea definitely , you own x% of Whatsapp assuming Facebook buys 100% of WhatApps which is in this case  How much shares of FaceBook do I need to own to have access to   WhatsApp's books? As WhatsApp is a privately held company by Facebook , Facebook is not obliged to reveal the books of WhatsApp , though some not all of the books of WhatsApp may appear in Facebook financial report , it really depends on Facebook Accounting policy.
