Advanta reported yesterday that its business card division produced net income of $5.6 million for the second quarter compared to $4.0 million last quarter. The increase resulted from significant improvements in portfolio yields. The average yield on the company’s business credit card portfolio, including fee income, increased this quarter to 21.72% from 20.36% last quarter due to increases in rates and higher fee income. A decrease in the net managed charge-off rate on business credit card loans from 5.61% last quarter to 5.22% this quarter also contributed to the increase in net income. Managed receivables for Advanta business cards at the end of the quarter were $886 million, up 6.5% from last quarter and 16.4% from the same quarter last year.
