As facts concerning contingencies become known to the Company, the Company reassesses its position with respect to accrued liabilities and other potential exposures. Estimates that are particularly sensitive to future change include legal matters, which are subject to change as events evolve, and as additional information becomes available during the administrative and litigation process.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;&lt;/font&gt;&amp;#160;&lt;/div&gt;&lt;div style="TEXT-INDENT: 18pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The Company&amp;#8217;s Western Auto subsidiary, together with other defendants including automobile manufacturers, automotive parts manufacturers and other retailers, has been named as a defendant in lawsuits alleging injury as a result of exposure to asbestos-containing products. The Company and some of its subsidiaries also have been named as defendants in many of these lawsuits. The plaintiffs have alleged that these products were manufactured, &lt;/font&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;distributed and/or sold by the various defendants. These products have primarily included brake parts. Many of the cases pending against the Company or its subsidiaries are in the early stages of litigation. The damages claimed against the defendants in some of these proceedings are substantial. Additionally, some of the automotive parts manufacturers named as defendants in these lawsuits have declared bankruptcy, which will limit plaintiffs&amp;#8217; ability to recover monetary damages from those defendants. Although the Company diligently defends against these claims, the Company may enter into discussions regarding settlement of these and other lawsuits, and may enter into settlement agreements, if it believes settlement is in the best interests of the Company&amp;#8217;s shareholders. The Company believes that many of these claims are at least partially covered by insurance. Based on discovery to date, the Company does not believe the cases currently pending will have a material adverse effect on the Company&amp;#8217;s operating results, financial position or liquidity. However, if the Company was to incur an adverse verdict in one or more of these claims and was ordered to pay damages that were not covered by insurance, these claims could have a material adverse affect on its operating results, financial position and liquidity. If the number of claims filed against the Company or any of its subsidiaries alleging injury as a result of exposure to asbestos-containing products increases substantially, the costs associated with concluding these claims, including damages resulting from any adverse verdicts, could have a material adverse effect on its operating results, financial position or liquidity in future periods.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 18pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;The Company is involved in various types of legal proceedings arising from claims of employment discrimination or other types of employment matters as a result of claims by current and former employees.&amp;#160;&amp;#160;The damages claimed against the Company in some of these proceedings are substantial. Because of the uncertainty of the outcome of such legal matters and because the Company&amp;#8217;s liability, if any, could vary widely, including the size of any damages awarded if plaintiffs are successful in litigation or any neg&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman"&gt;otiated settlement, the Company cannot reasonably estimate the possible loss or range of loss which may arise.&amp;#160;&amp;#160;The Compan&lt;/font&gt;y is also involved in various other claims and legal proceedings arising in the normal course of business. Although the final outcome of these legal matters cannot be determined, based on the facts presently known, it is management&amp;#8217;s opinion that the final outcome of such claims and lawsuits will not have a material adverse effect on the Company&amp;#8217;s financial position, results of operations or liquidity.&lt;/font&gt;&lt;/div&gt;</NonNumbericText><NonNumericTextHeader>17.
