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 defects can be caused by cold dies, low metal temperature, dirty metal, lack of venting, or too much lubricant. Other possible defects are gas porosity, shrinkage porosity, hot tears, and flow marks. Flow marks are marks left on the surface of the casting due to poor gating, sharp corners, or excessive lubricant.
