Preaching to the Choir
Everytime the Friday Telex says "currency worked in our favour".... it really means "currency worked against HK staff".... the company know this better than you as they have been playing this game a long time.
Revenue is generated in a mix of USD and "Other currencies". As the USD falls the "other currencies" take on greater value for the company. The company's cost are predominately based in USD being Fuel and Aircraft and staff (mainly HK based). Therefore as the USD falls, Revenue (expressed in HKD) rise; costs are broadly unchanged and profit (expressed in HKD) rises. Good news for the bottom line figure; questionable news for the UK investor(s)......
Under the new regime... if you don't like it leave.... enough guys leave and maybe.... possibly maybe.... you may see a currency mechanism in your salary. In the meantime... this is a waste of bandwidth....
