15.  Commitments and Contingencies
 
Self-Insurance
 
It is our policy to self-insure, up to certain limits, traditional risks including workers’ compensation, comprehensive general liability, and auto liability. Our self-insured deductible for each claim involving workers’ compensation, and auto liability is limited to $0.8 million and $2.0 million, respectively. Our self-insured retention for each claim involving comprehensive general liability (including product liability claims) is limited to $0.8 million.  We are also self-insured up to certain limits for certain other insurable risks, primarily physical loss to property, excluding natural catastrophes  ($0.1 million per occurrence), Director and Officer ($0.8 million per occurrence) and the majority of our medical benefit plans ($0.3 million per occurrence). Insurance coverage is maintained for catastrophic property and casualty exposures as well as those risks required to be insured by law or contract. A provision for claims under this self-insured program, based on our estimate of the aggregate liability for claims incurred, is revised and recorded annually. The estimate is derived from both internal and external sources including but not limited to actuarial estimates. The actuarial estimates are subject to uncertainty from various sources, including, among others, changes in claim reporting patterns, claim settlement patterns, judicial decisions, legislation, and economic conditions. Although, we believe that the actuarial estimates are reasonable, significant differences related to the items noted above could materially affect our self-insurance obligations, future expense and cash flow. At December 29, 2012 and December 31, 2011, the self-insurance reserves totaled $7.2 million and $7.6 million, respectively. We incurred $10.7 million in expense and $11.1 million in payments, net of reimbursements in fiscal 2012 related to our workers compensation, auto, general liability and health and welfare reserves. We incurred $12.8 million in expense and payments, net of reimbursements in fiscal 2011 related to our workers compensation, auto, general liability and health and welfare reserves.

Environmental and Legal Matters
 
We are involved in various proceedings incidental to our businesses and are subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which we operate. Although the ultimate outcome of these proceedings cannot be determined with certainty, based on presently available information management believes that adequate reserves have been established for probable losses with respect thereto. Management further believes that the ultimate outcome of these matters could be material to operating results in any given quarter but will not have a materially adverse effect on our long-term financial condition, our results of operations, or our cash flows.
 
Collective Bargaining Agreements
 
As of December 29, 2012, approximately 30% of our employees were represented by various labor unions.  As of December 29, 2012, we had 42 collective bargaining agreements, of which 10, covering approximately 132 total employees, are up for renewal in fiscal 2013.  We consider our relationship with our employees generally to be good.
