If you made nondeductible (and therefore nontaxable) contributions to your traditional IRA, you have to treat each distribution (including a conversion to a Roth IRA, if applicable) as one part nontaxable return of cost basis (your nondeductible contributions) and one part taxable earnings.
Product defects are generally put into three categories: design defects, manufacturing defects and marketing defects. Marketing defects are defects in the manner in which a product is sold. This type of defect can include inadequate warnings and/or instructions. Design defects are in a manner of speaking, intended. This type of defect is inherent in the design of the product.
If an accident is caused by a defective product, the manufacturer and seller of the product are both liable even if the injured person doesn't know which one was careless in creating or allowing the defect, or exactly how the defect happened. (For more information, see Proving a Defective Product Liability Claim.)
