Our long-term investment in a municipal bond is comprised of debt obligations issued by states, cities, counties and other governmental entities, which earn federally tax-exempt interest. Our investment in an auction rate security (“ARS”) has a stated term to maturity of greater than one year, and as such, we classify our investment in ARS as non-current on our condensed consolidated balance sheets within other assets. Auctions can “fail” when the number of sellers of the security exceeds the buyers for that particular auction period. In the event that an auction fails, the interest rate resets at a rate based on a formula determined by the individual security. The ARS for which auctions have failed continues to accrue interest and is auctioned on a set interval until the auction succeeds, the issuer calls the security, or it matures. As of June 30, 2015, we have determined this investment is at risk for impairment due to the nature of the liquidity of the market over the past several years. Cumulative unrealized losses as of June 30, 2015 amount to $0.5 million and are reflected within accumulated other comprehensive loss as a component of stockholders’ equity. We believe this impairment is temporary, as we do not intend to sell the investment and it is unlikely we will be required to sell the investment before recovery of its amortized cost basis.

Our non-governmental debt securities primarily consist of corporate bonds and commercial paper. Our treasury and federal agencies primarily consist of U.S. Treasury bills and federal home loan debt securities. We do not intend to sell our investments in these securities and it is not likely that we will be required to sell these investments before recovery of the amortized cost basis.

Fair Value Measurements

FASB ASC Topic 820 – Fair Value Measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of June 30, 2015, we held investments that are required to be measured at fair value on a recurring basis. These investments (available-for-sale) consist of non-governmental debt securities, treasury and federal agencies and municipal bonds that are publicly traded and our investment in an ARS. Available for sale securities included in Level 2 are estimated based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Our investment in an ARS is categorized as Level 3 and fair value is estimated utilizing a discounted cash flow analysis as of June 30, 2015 which considers, among other items, the collateralization underlying the security investment, the credit worthiness of the counterparty, the time of expected future cash flows, and the expectation of the next time the security is expected to have a successful auction. The auction event for our ARS investment has failed for multiple years. The security was also compared, when possible, to other observable market data with similar characteristics.

Investments measured at fair value on a recurring basis subject to the disclosure requirements of FASB ASC Topic 820 – Fair Value Measurements at June 30, 2015 and December 31, 2014 were as follows (dollars in thousands):

Equity Method Investment

Our investment in an equity affiliate, which is recorded within other noncurrent assets on our condensed consolidated balance sheet, represents an international investment in a private company. As of June 30, 2015, our investment in an equity affiliate equated to a 30.7%, or $4.2 million, non-controlling interest in CCKF, a Dublin-based educational technology company providing intelligent adaptive systems to power the delivery of individualized and personalized learning. During the quarter ended June 30, 2015, we recorded less than $0.1 million of loss related to our proportionate investment in CCKF within miscellaneous expense on our unaudited condensed consolidated statements of loss and comprehensive loss. In the prior year quarter, this investment was recorded as a cost method investment.

Credit Agreement

During the fourth quarter of 2014, the Company; its wholly-owned subsidiary, CEC Educational Services, LLC (“CEC-ES”); and the subsidiary guarantors thereunder entered into a First Amendment (the “First Amendment”) to its Amended and Restated Credit Agreement dated as of December 30, 2013 (as amended, the “Credit Agreement”) with BMO Harris Bank N.A. (“BMO Harris”), in its capacities as the initial lender and letter of credit issuer thereunder and the administrative agent for the lenders which from time to time may be parties to the Credit Agreement, to among other things, increase the revolving credit facility to $120.0 million. The revolving credit facility under the Credit Agreement is scheduled to mature on June 30, 2016. The loans and letter of credit obligations under the Credit Agreement are required to be secured by 100% cash collateral. As of June 30, 2015, there were no outstanding borrowings under the revolving credit facility.
