This morning Burberry has announced an 11 percent surge in revenue for the year ending March 31st, 2015.

Sales amounted to £2.5bn and adjusted profit after tax increased by 7 percent to £456m - but the company's stock has taken a hammering, and fallen by over 5 percent.

This due to the effect of foreign exchange rate swings - when they are taken into account, profits fell by 1 percent as the company was hit by the strength of the Swiss franc, the dollar, and the falling value of the euro.

As these currency fluctuations are likely to continue, Burberry has warned that this will affect profits into 2016.

This has caused the company to forecast that wholesale profits in 2015-16 will be £40m lower than they were previously expected to be.

The fashion firm comments that British-made trench coats and cashmere scarves were the principal drivers of growth during the year, and that the brand has invested heavily in its own digital platforms and that these ventures have outperformed expectations in all regions.

Christopher Bailey, chief creative and chief executive officer commented on the results: "We are pleased to report a strong full year performance, with revenue up 11 percent and adjusted profit up 7 percent underlying. Against a challenging external backdrop, our global team has focused ever more intensely on our core, including celebrating the British-made products that are our brand signature and extending our online and offline integration."

He continues: "At this early stage of the year, we are seeing increased uncertainty in some markets. Against this background, we will continue to manage our business dynamically - capitalising on the significant opportunities we have by channel, region and product to create long-term shareholder value."
