I just found few interesting pieces on the net in regards to filing that took place on Friday. So far I did good with my investment in PTI and looking at what has happened in past few weeks with the share price and then a price surge on Friday makes me think that a public offering will take place. IMO of course. As Rob wrote it "next two weeks should be interesting".

Short Form Prospectus

Prospectus generally refers to the offering document used by the issuer and the underwriters to market a public offering of securities.

A short form prospectus can be used by issuers that meet certain issuer and transaction requirements established by the applicable Securities Regulatory Authorities in Canada. The procedure and forms for filing a preliminary short form prospectus and a short form prospectus are contained in National Instrument 44-101 — Short Form Prospectus Distributions (on or after January 1, 2011) (NI 44-101) .

The short form prospectus consists primarily of the specific transaction information. Form 44-101F1(on or after April 20, 2012) — Short Form Prospectus allows incorporation by reference of certain required information about the issuer from documents previously filed pursuant to the Applicable Securities Laws.

The preliminary short form prospectus is essentially the first draft of the short form prospectus filed with the applicable Securities Regulatory Authorities in Canada in the jurisdictions where the securities are to bedistributed and may omit certain information relating to the offering (such as the final offering price). The short form preliminary prospectus is also known as the "red herring" because of the red ink used on the front page, which indicates that some information, including the price and size of the offering, is subject to change.

The final short form prospectus is an updated version of the preliminary short form prospectus, contains all final offering information (such as pricing and underwriting details) and reflects amendments to the short form prospectus subsequent to the date of the preliminary short form prospectus.

A red herring prospectus, as a first or preliminary prospectus, is a document submitted by a company (issuer) as part of a public offering of securities (eitherstocks or bonds). Most frequently associated with an initial public offering (IPO), this document, like the previously submitted Form S-1 registration statement, must be filed with the Securities and Exchange Commission (SEC).

A red herring prospectus is issued to potential investors, but does not have complete particulars on the price of the securities offered and quantum of securities to be issued.[1] The front page of the prospectus displays a bold red disclaimer stating that information in the prospectus is not complete and may be changed, and that the securities may not be sold until the registration statement, filed with the market regulator, is effective.[2] Potential investors may not place buy orders for the security, based solely on the information contained within the preliminary prospectus. Those investors may, however, express an "indication of interest" in the offering, provided that they have received a copy of the red herring at least 48 hours prior to the public sale. After the registration statement becomes effective, and the stock is offered to the public, indications of interest may be converted to purchase orders, at the buyer's discretion. The final prospectus must then be promptly delivered to the buyer.
