why are companies, going from public to private? What are the advantages of each?

Answer 1

A public company has several advantages. It is able to raise funds and capital through the sale of its securities. This is the reason why public corporations are so important, historically; prior to their existence, it was very difficult to obtain large amounts of capital for private enterprises. In addition to the ease of raising capital, public companies may issue their securities as compensation for those that provide services to the company, such as their directors, officers and employees. While private companies may also issue their securities as compensation for services, the recipent of those securities often have difficulty selling those securities on the open market. Securities from a public company, typically have an established fair market value at any given time as determined by the price the security is sold for on the stock exchange where the security is traded.

Reasons for delisting -
Companies may decide to deregister for a variety of reasons that can be either good or bad for shareholders. A few of the most common reasons include:
Capital Savings - The costs of being a publicly traded company are substantial and are occasionally difficult to justify with a low market capitalization, especially after Sarbanes Oxley laws called for increased disclosures. As a result, deregistering can save a company millions and reward shareholders with a higher net income and earnings per share (EPS).

Strategic Move - Shares of the company may be trading below intrinsic value, compelling the company to acquire its own shares as a strategic move. This typically results in shareholders being rewarded with substantial returns over the short term.

Regulatory Concerns - Stock exchanges such as the Nasdaq and New York Stock Exchange have minimum requirements to remain listed. If a company does not meet those requirements, it may be forced to delist itself. Causes for delisting may include failure to file timely financial reports, lower-than-required stock price, or insufficient market capitalization. (For more see, The Tale Of The Two Exchanges. )
In the end, companies can have a clear bottom-line incentive for delisting their stock from public exchanges - it's not always a bad thing!

Answer 2

A public company gets it's funding from stockholders but then has to share profits. Going private after reaching a certain point allows the company to keep more profit but it also cuts off investment funding.
