TransUnion, a provider of credit information to banks and consumers, said Advent International Corp. and Goldman Sachs Group Inc. (GS)’s private equity unit agreed to buy the company from Madison Dearborn Partners and the Pritzker family in the largest leveraged-buyout deal this year.

The transaction, which is expected to be completed by early in the second quarter, values the company at more than $3 billion, according to a statement today from TransUnion. The Chicago-based firm had total debt of $1.6 billion last year, according to public filings, and is preparing to take on $600 million more, according to a Standard & Poor Financial Service’s report issued today, valuing the equity component of the transaction at about $800 million.
