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.
It is irrelevant whether the manufacturer or supplier exercised great care; if there is a defect in the product that causes harm, he or she will be liable for it. The law of products liability is found mainly in common law (state judge-made law) and in the Uniform Commercial Code.
