[1] The carrying value represents the consolidated financial statement amount of the debt which excludes the allocation of the conversion feature to equity, while the fair value is based on quoted market prices for Level 1 convertible notes which include the equity feature and internally developed valuation techniques such as discounted cash flow modeling for Level 3 convertible notes which include the equity feature.
