The website includes information about exchange traded notes (ETNs) issued by Bank of Montreal. As discussed in more detail on the website, the ETNs are not suitable for all investors. In particular, the ETNs should be purchased only by sophisticated investors who do not intend to hold the ETNs as a buy and hold investment, who are willing to actively and continuously monitor their investment and who understand the consequences of investing in and of seeking daily resetting or daily resetting inverse leveraged investment results. The ETNs are designed to achieve their stated investment objectives on a daily basis. You should proceed with extreme caution in considering an investment in the ETNs.
