> Companies have a lot of tools at their disposal to hide things on their balance sheet for a while. However when that happens it typically means the numbers are bad. Really bad. If they weren’t, they’d do everything they can to highlight how great the investment is going.

There are many legitimate reasons to not disclose an investment on your balance sheet:

- materiality: immaterial compared to overall position

- classification: research-phase or contingent on future event

- control & ownership: if you don't have significant control or ownership

- off-balance sheet arrangements: SPVs, JVs, lease agreements that don't meet consolidation criteria (disclosed in notes, but not recognized as assets or liabilities due to limited exposure)

- strategy or confidentiality: minimize visibility to protect competitive information or negotiations; must still comply with disclosure rules so details might appear in aggregated or summarized form

- regulatory or accounting policy differences: IFRS vs. US GAAP have different recognition and measurement bases

- held-for-trading or short-term nature: e.g. marketable securities might be short-term trading assets so would be grouped together in a single line item, rather than disclosed separately
