IPSL must disclose information: I believe that IPSL is a 501c non profit and, as such, must disclose their filings.
"Public access must be provided promptly on request by allowing inspection of the documents at the organization's office or offices, and by providing copies of the documents promptly in response to any in-person request or within 30 days for a written request. However, organizations don't have to provide copies if they make these materials widely available through publication on the Internet, or if the IRS determines that the organization is being subject to a harassment campaign. The organization is permitted to require a payment in advance for actual postage costs incurred, and a copying fee of up to $1 for the first page and $0.15 for each page thereafter. The request may be for only certain documents, or only certain portions of documents, in which case the charges must be for only those pages. NPO staff members who fail to comply with the new law and regulations are personally subject to fines and other penalties (i.e. the person refusing to provide public access gets fined, not the organization)."
