Commitments and Contingencies |
Commitments and Contingencies | 12. Commitments and Contingencies Leases We lease certain facilities and equipment under noncancelable operating leases. Rent expense for the years ended December 31, 2012, 2011 and 2010 was $15.2 million, $12.0 million, and $12.8 million, respectively. We recognize escalating rental payments that are quantifiable at the inception of the lease on a straight-line basis over the lease term. Concurrent with the acquisitions of certain companies, we entered into various agreements with previous owners to lease buildings used in our operations. The terms of these leases generally range from three to ten years and certain leases provide for escalations in the rental expenses each year, the majority of which are based on inflation. Included in the 2012, 2011 and 2010 rent expense above are approximately $3.4 million, $2.2 million and $2.3 million of rent paid to these related parties, respectively. The following represents future minimum rental payments under noncancelable operating leases (in thousands):

Claims and Lawsuits We are subject to certain legal and regulatory claims, including lawsuits arising in the normal course of business. We maintain various insurance coverages to minimize financial risk associated with these claims. We have estimated and provided accruals for probable losses and related legal fees associated with certain litigation in the accompanying consolidated financial statements. While we cannot predict the outcome of these proceedings, in management's opinion and based on reports of counsel, any liability arising from these matters individually and in the aggregate will not have a material effect on our operating results or financial condition, after giving effect to provisions already recorded. In December 2011, we received a letter from Ferguson Enterprises, Inc. ("Ferguson"), a distributor of plumbing supplies and pipe, in which Ferguson stated that it had unintentionally supplied us with gaskets that were mislabeled by a former supplier as being non-asbestos. Ferguson currently states that we bought approximately 34,000 gaskets that might have been mislabeled. Ferguson further disclosed that four Ferguson customers had found asbestos in gaskets above the 1% level at which they can be classified as non-asbestos. No reasonable estimate of liability, if any, is possible at this time. Surety Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a financial institution known as a surety. If we fail to perform under the terms of a contract or to pay subcontractors and vendors who provided goods or services under a contract, the customer may demand that the surety make payments or provide services under the bond. We must reimburse the surety for any expenses or outlays it incurs. To date, we are not aware of any losses to our sureties in connection with bonds the sureties have posted on our behalf, and do not expect such losses to be incurred in the foreseeable future. Surety market conditions are currently challenging as a result of significant losses incurred by many sureties in recent periods, both in the construction industry as well as in certain larger corporate bankruptcies. As a result, less bonding capacity is available in the market and terms have become more restrictive. Further, under standard terms in the surety market, sureties issue bonds on a project-by-project basis, and can decline to issue bonds at any time. Historically, approximately 25% to 35% of our business has required bonds. While we have strong surety relationships to support our bonding needs, current market conditions as well as changes in the sureties' assessment of our operating and financial risk could cause the sureties to decline to issue bonds for our work. If that were to occur, the alternatives include doing more business that does not require bonds, posting other forms of collateral for project performance such as letters of credit or cash, and seeking bonding capacity from other sureties. We would likely also encounter concerns from customers, suppliers and other market participants as to our creditworthiness. While we believe our general operating and financial characteristics, including a significant amount of cash on our balance sheet, would enable us to ultimately respond effectively to an interruption in the availability of bonding capacity, such an interruption would likely cause our revenue and profits to decline in the near term. Self-Insurance We are substantially self-insured for workers' compensation, employer's liability, auto liability, general liability and employee group health claims, in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. Loss estimates associated with the larger and longer-developing risks, such as workers' compensation, auto liability and general liability, are reviewed by a third-party actuary quarterly. Our self-insurance arrangements currently are as follows: Workers' Compensation— The per-incident deductible for workers' compensation is $500,000. Losses above $500,000 are determined by statutory rules on a state-by-state basis, and are fully covered by excess workers' compensation insurance. Employer's Liability— For employer's liability, the per incident deductible is $500,000. We are fully insured for the next $500,000 of each loss, and then have several layers of excess loss insurance policies that cover losses up to $100 million in aggregate across this risk area (as well as general liability and auto liability noted below). General Liability— For general liability, the per incident deductible is $500,000. We are fully insured for the next $1.5 million of each loss, and then have several layers of excess loss insurance policies that cover losses up to $100 million in aggregate across this risk area (as well as employer's liability noted above and auto liability noted below). Auto Liability— For auto liability, the per incident deductible is $500,000. We are fully insured for the next $1.5 million of each loss, and then have several layers of excess loss insurance policies that cover losses up to $100 million in aggregate across this risk area (as well as employer's liability and general liability noted above). Employee Medical— We have two medical plans. The deductible for employee group health claims is $300,000 per person, per policy (calendar) year for each plan. Insurance then covers any responsibility for medical claims in excess of the deductible amount. Our $100 million of aggregate excess loss coverage above applicable per-incident deductibles represents one policy limit that applies to all lines of risk; we do not have a separate $100 million of excess loss coverage for each of general liability, employer's liability and auto liability. Companies acquired may have a self-insurance plan in place on the date of acquisition. Generally, the acquired company will remain on a separate policy until the end of the coverage period upon which the acquired company will join the aforementioned self-insurance policy.
