United Parcel Service Inc (UPS), the world's biggest courier company, said on Thursday it ratified a five-year contract with higher wages and benefits for 125,000 unionized employees represented by the International Brotherhood of Teamsters.

The company said it expected to take a pre-tax charge of about $1.05 billion in the second quarter due to the health and welfare changes in the newly-ratified plan. 

The company reported a 12% fall in first-quarter profit earlier on Thursday.
