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.
The duty to warn arises in product liability cases, as manufacturers can be held liable for injuries caused by their products if the product causes an injury to a consumer and the manufacturer fails to supply adequate warnings about the risks of using the product (such as side effects from pharmacy prescriptions) or if they fail to supply adequate instructions for the proper use of the product (such as a precaution to use safety glasses when using a drill).
