JP Morgan Chase reported first quarter financial results this morning. The dynamics reported in its card business this quarter include revenue essentially flat but net income up substantially - 73 percent - over the prior year due primarily to lower bankruptcy-related credit losses. As with some other issuers this quarter, Chase reported a 5.6 percent decline in its outstanding loans over the prior quarter as consumers paid off balances at an accelerated rate - at least partially due to changes in the minimum payment amount due on outstanding balances.
