Ceridian HCM Holding filed a prospectus with U.S Securities and Exchange Commission seeking to be listed on the Toronto Stock Exchange (TSX) and the New York Stock Exchange (NYSE) under the ticker symbol “CDAY.”

The IPO is expected to take place on April 26 and the company hopes to raise more than $500 million. The Minneapolis-based human resources software company is also looking to raise an additional $100 million shares in private placement.

Although the headquarters of Ceridian is in Minneapolis, it is management is based in Toronto, under the leadership of CEO David Ossip. The company said on Thursday that it would make 21 million shares available to the public at a price range of $19 and $21.

Deutsche Bank, Canaccord Genuity, Goldman Sachs, Credit Suisse, and JP Morgan are the acting as the underwriters of the IPO. CIBC Capital Markets, Barclays, Jefferies, Wells Fargo Securities and Citigroup are the book-running managers for the IPO. MUFG, Baird, Piper Jaffray, Canaccord Genuity, and William Blair are acting as the co-managers.

Ceridian would be valued at around $3 billion if sold all the 21 million shares at its current price range. The company wants to use its net earnings to settle the $475 million principal of its remaining 11% senior notes that are due three years from now, and also pay a part of the interest.

Private equity firm Fidelity National Financial and Thomas H. Lee Partners invested $150 million in the company twelve years ago, before privatizing it in 2007 for close to $5.3 billion.

Ceridian is among the oldest tech companies in the US. It gained a lot of attention after acquiring Dayforce, Inc. (Toronto) in 2011 for more than $100. Dayforce belonged to Mr. Ossip Inc., but he was immediately made the CEO of the combined company after the sale.

Ossip had also previously been in charge of the Workbrain Corp., another successful human resource software company that is based in Toronto. The CEO has transitioned Ceridian into a leading, web-based subscription software company that had once declined to payroll processor.
