13. SELF-INSURANCE RESERVE FOR LOSSES AND LOSS ADJUSTMENT EXPENSES
The activity in the reserve for losses and loss adjustment expenses is summarized as follows:
The provision for unpaid loss and loss adjustment expenses decreased by $9 million in 2011 and $8 million in 2010 as a result of changes in estimates from insured events of the prior years due to changes in underwriting experience and frequency and severity trends. Our year-end 2011 self-insurance reserve of $330 million consisted of a current portion of $99 million and long-term portion of $231 million. Our year-end 2010 self-insurance reserve of $313 million consisted of a current portion of $98 million and long-term portion of $215 million.
