Surpassing the expectations of the analysts, McDonald's Corp. has reported a 4.8% surge in the sale store sales in May. It said that it has been estimating its rates for foreign-exchange to affect its yearly income.

It added that, as per the predictions, the rates are going to affect the income in the second quarter. Nearly 25% of the Company's stakes are owned by the euro zone giants.

The food chain giant shared that its overall sales at all of its units across the world have jumped by 5.5% in May.

McDonald's has balanced its menu by placing less expensive and more expensive products in order to cope with the instability in the economy. It has been viewed as its approach for outdoing its competitors in the market.

Its sector margins are expected to face the heat due its opposition towards price rise. It has refused to raise the costs, despite noting the surge in the prices of beef.

In US, its same-store sales have advanced by 3.4% due to the rising strength in sales at McCafe coffee drink outlets. Also, items like ice-coffee frappes, Chicken McNugget and Happy Meal, which have been added to its menu lately, have contributed to the surge in the sales.
