The head of Asiana Airlines apologised to investors Monday for the company's lacklustre business performance last year, saying that he will do his best to improve its bottom line. Asiana Airlines reported KRW151.9b (US$129.8m) in net loss last year, with its debt ratio spiking to 991.5%. The airline is currently pushing for restructuring including consolidation of overlapping businesses, early retirement schemes and other business normalisation efforts. "I feel sorry for failing to create profit last year and I assure you, we will tide over cumulative losses once and for all this year and do our best to fulfil our corporate responsibly and role in increasing the benefit and convenience of stakeholders," Asiana Airlines CE Kim Soo-cheon told investors. <br/>
