A change in how the most widely used credit score in the U.S. is tallied will likely make it easier for tens of millions of Americans to get loans, the Wall Street Journal reported today. Fair Isaac Corp. said Thursday that it will stop including in its FICO credit-score calculations any record of a consumer failing to pay a bill if the bill has been paid or settled with a collection agency. The San Jose, Calif., company also will give less weight to unpaid medical bills that are with a collection agency. The moves follow months of discussions with lenders and the Consumer Financial Protection Bureau aimed at boosting lending without creating more credit risk. Since the recession, many lenders have approved only the best borrowers, usually those with few or no blemishes on their credit report.
