(1) The values of investment securities, including mutual funds, are classified as cash and cash equivalents ($8.8 million and $2.3 million as of September 30, 2013 and December 31, 2012, respectively) and other assets ($10.0 million and $9.2 million as of September 30, 2013 and December 31, 2012, respectively). For publicly-traded mutual funds, fair value is determined on the basis of quoted market prices and, accordingly, such investments have been classified as Level 1. Other investment securities are valued at the net asset value per share or unit multiplied by the number of shares or units held as of the measurement date and have been classified as Level 2. The Company determines the fair value of its derivative instruments using standard pricing models and market-based assumptions for all significant inputs, such as yield curves and quoted spot and forward exchange rates. Accordingly, the Company’s derivative instruments are classified as Level 2. Non-recurring Fair Value Measurements The Company’s nonfinancial assets which are measured at fair value on a nonrecurring basis include property, plant and equipment, goodwill, intangible assets and certain other assets. During the three months ended September 30, 2013, the Company performed the annual impairment tests of goodwill and indefinite-lived intangible assets and concluded that no impairment charges were necessary. In testing goodwill and indefinite-lived intangible assets for impairment, management relies on a number of factors including operating results, business plans, economic projections, anticipated future cash flows, transactions, and market place data. Accordingly, these fair value measurements fall in the Level 3 category of the fair value hierarchy. The factors used by management in the impairment analysis are inherently subject to uncertainty. While the Company believes it has made reasonable estimates and assumptions to determine the fair value of its reporting units, if actual results are not consistent with management's estimates and assumptions, goodwill and other intangible assets may be overstated and could potentially trigger impairment charges. During the nine months ended September 30, 2013, impairments associated with plans to dispose of certain property, plant and equipment were not material, other than those associated with the divestiture of the Teach platform business. During the nine months ended September 30, 2013, the Company recorded non-cash pretax charges of $22.7 million associated with impairments of goodwill, intangibles and other long-lived assets of the Teach platform business. The impairments were estimated based on the proceeds expected to be realized upon disposition of the assets. In the absence of a definitive sales price for these and similar types of assets, the Company generally uses projected cash flows, discounted as necessary, or market multiples to estimate the fair values of the impaired assets. Key inputs into the projected cash flows include management’s projections of cash flows on a held-and-used basis (if applicable), management’s projections of cash flows upon disposition and discount rates. Key inputs into the market multiple approach include identifying companies comparable to the Company’s business and estimated control premiums. Accordingly, these fair value measurements fall in the Level 3 category of the fair value hierarchy. These assets and certain liabilities are measured at fair value on a nonrecurring basis as part of the Company’s impairment assessments and as circumstances require. Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, derivative instruments, notes payable and short and long-term debt. The carrying values for current financial assets and liabilities, including cash and cash equivalents, accounts receivable, accounts payable and short-term debt approximate fair value due to the short maturity of such instruments. The fair values of the Company’s derivative instruments are recorded in the Condensed Consolidated Balance Sheets and are disclosed in Footnote 7. The fair values of the Company’s medium-term notes are based on quoted market prices (Level 1) and are as follows (in millions):
| September 30, 2013 |  | December 31, 2012
| Fair Value |  | Book Value |  | Fair Value |  | Book Value
Medium-term notes | $ | 1,752.2 |  |  | $ | 1,669.2 |  |  | $ | 1,803.6 |  |  | $ | 1,703.9 |
The carrying amounts of all other significant debt approximate fair value.
