The number of banks that didn't make their monthly dividend payments on TARP funds skyrocketed to 29 in August, up from 18 in May. Banks can choose not to make payments during a given month, allowing the dividends owed to accumulate unpaid.

Failure to pay may be a sign of financial distress. Obviously banks that are short of capital may decide to retain funds rather than pay off the TARP.
