roll rate
n.— «We’re in the late stages of the financial disaster of 2008, but another crisis looms: The consumer recession. According to the Wall Street Journal, more and more credit-card holders are falling behind on their payments and, eventually, defaulting. The industry calls these defaults “roll rates,” and the trend is increasing, for the most part, across all credit card companies. Among borrowers between 60 to 89 days late on payments, nearly a fifth of balances are being dimissed as uncollectible.» —“Two Ways To Play: Credit Card Crunch” by Terry Woo Minyanvile Dec. 11, 2008.
