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.
These statutory provisions can be very diverse such that the United States Department of Commerce has promulgated a Model Uniform Products Liability Act (MUPLA) for voluntary use by the states. There is no federal products liability law. In any jurisdiction one must prove that the product is defective. There are three types of product defects that incur liability in manufacturers and suppliers: design defects, manufacturing defects, and defects in marketing.
