OSIM International's fourth-quarter net profit rose 22 per cent year on year to $27.6 million, the group's 20th consecutive quarter of rise.

Revenue for the three months ended Dec 31, 2013, rose 15.5 per cent to $178.6 million, as a result of higher consumer demand from OSIM's range of wellness products.

Boosting the bottom line was $42.1 million in gain arising from the fair value of TWG Tea in other operating income, though this was partially offset by the $31 million impairment and foreign translation loss of Brookstone.
