Topeka ? Protection One has been notified that its stock has fallen below the minimum price on the New York Stock Exchange and may be removed from listing.

The stock exchange requires that stocks trade at a minimum of $1 for 30 days.

Shares of Protection One, a monitored security company, last traded at 88 cents. Shares of Protection One have not been above the NYSE minimum since closing at $1.01 on June 27.

In a statement released Tuesday, Topeka-based Protection One said that it planned to return to NYSE compliance within six months.

However, if the stock was removed, Protection One said it believed other trading sites were available.

The news is the latest in a string of events surrounding the company and efforts by its parent company, Westar Energy, to divest of its ownership. Westar, the largest electric utility in Kansas, owns 88 percent of Protection One.
