Vista International Group, whose software technology manages cinema operations worldwide, has told share-market operator NZX it has no explanation for a 27 percent decline in its shares since early January.
From January 5 to February 15 the price of the Auckland company's shares dropped $1.60 from $5.85 to $4.25, prompting the letter from the NZX on whether it had disclosed all material information to the market as required under the continuous disclosure rules.
Vista's director commercial and legal Brian Cadzow wrote back that it had complied with its market obligations.
