Aviv REIT Inc, a real estate investment trust that focuses on healthcare properties, postponed its initial public offering, which had been scheduled to price on Tuesday, according to one of the company's underwriters.

Aviv and some shareholders planned to sell 16.6 million shares at a price range between $17 and $19 a share, according to an Oct. 29 filing with the Securities and Exchange Commission.

The company has not yet scheduled a new date for the offering, the underwriter said.
