While the specifics are a little technical, the IPO will include 365 million shares of common stock and 50 million shares of Series B mandatory convertible junior preferred stock.

After months of speculation and debate, General Motors has announced details about their public offering.

While the specifics are a little technical, the IPO will include 365 million shares of common stock and 50 million shares of Series B mandatory convertible junior preferred stock. The common stock is expected to be priced from $26 to $29 per share, while the Series B stock will go for $50 per share.

Speaking of the latter, "each share of the Series B preferred stock will automatically convert on the mandatory conversion date, which is expected to be three years from the original issue date. The conversion provisions depend on the applicable market value of the company's common stock, and are subject to certain anti-dilution adjustments."

Overall, the IPO could be worth as much as $13 billion dollars. However, underwriters (aka banks) have an option to release an additional 54.75 million shares of common stock and 9 million shares of Series B preferred stock to cover "over-allotments."

If everything is approved by the Securities and Exchange Commission (SEC), the GM public offering will kick off on November 18th.
