IDT Holdings Singapore (I05.SG) last +10.4% at 3-year high of $0.53, closing in on $0.54/share price offered by parent IDT International (0167.HK) to take company private, says Dow Jones.

Volume remains thin despite gains, although not surprising as investors generally wary of company given its money-losing streak.

Small free float, with parent owning 77.86% stake, another reason behind LCD consumer electronics maker's historically low trading liquidity. Based on orderbook quotes, stock likely to hold around current levels for some time.

Offer represents 12.5% premium to yesterday's close, 19.0% premium to average price over past month. IDT Holdings in process of engaging independent financial adviser to assist on deal.
