Are there any schedules or attachments associated with Form 990-PF?

When filing IRS Form 990-PF, you may need to attach Schedule B as an attachment along with your return. Filing this schedule is mandatory for private foundations if it has directly or indirectly received money, properties, or any other securities worth $5000 or more from a person during the tax year. If not, then you're not required to attach Schedule B in the information return.
 
The term 'Person' mentioned can either be an individual or fiduciaries, partnerships, corporations, associations, trusts, and exempt organizations.
