12. SELF-INSURANCE RESERVE FOR LOSSES AND LOSS ADJUSTMENT EXPENSES
The following table summarizes the activity in our self-insurance reserve for losses and loss adjustment expenses for the last two fiscal years:
Our provision for unpaid loss and loss adjustment expenses decreased by $11 million in 2012 and $9 million in 2011 as a result of changes in estimates from insured events from prior years due to changes in underwriting experience and frequency and severity trends. Our year-end 2012 self-insurance reserve of $342 million consisted of a current portion of $103 million and long-term portion of $239 million. 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.
