On August 28, 2015, Ancestry.com Inc. (the “Borrower”), a subsidiary of Ancestry.com LLC (the “Company”), repaid all amounts outstanding under its existing senior secured credit facilities (the “Existing Credit Facilities”) and terminated the Existing Credit Facilities and the obligations thereunder under the Credit and Guaranty Agreement dated as of December 28, 2012, among the Company, as a guarantor, Ancestry US Holdings Inc., as a guarantor (“US Holdings”), the Subsidiary Guarantors parties thereto, the several lenders parties thereto and Barclays Bank PLC, as administrative agent.

On August 28, 2015, the Company entered into a new Credit and Guaranty Agreement with the Borrower, US Holdings, the Subsidiary Guarantors parties thereto (the “Subsidiary Guarantors”), the several lenders parties thereto and Morgan Stanley Senior Funding, Inc., as administrative agent. The new credit facilities thereunder (the “New Credit Facilities”) consist of (x) a $735.0 million term loan facility that matures on August 29, 2022 and (y) an $80.0 million revolving credit facility that matures on August 28, 2020 (however, if the Borrower’s 11.00% Senior Notes due 2020 (the “Senior Notes”), issued pursuant to the Senior Notes Indenture dated as of December 28, 2012, are outstanding 91 days prior to the maturity date of the Senior Notes (the “Springing Maturity Date”), each of the New Credit Facilities will mature on the Springing Maturity Date). The Company, US Holdings and certain subsidiaries of the Company, US Holdings and the Borrower guarantee the New Credit Facilities (collectively, the “Guarantors”). All obligations under the New Credit Facilities and the related guarantees are secured by a perfected first priority lien in substantially all of the Borrower’s and the Guarantors’ tangible and intangible assets.

The New Credit Facilities also provide for a swingline subfacility of $25.0 million, a letter of credit subfacility of $50.0 million and an uncommitted incremental facility in an amount not to exceed the sum of (i) an unlimited amount if, after giving effect to incurrence, the total net secured leverage ratio is less than or equal to 3.00 to 1.00, (ii) all prior voluntary prepayments, and (iii) $100.0 million, subject to certain conditions. The term loan borrowings currently bear interest at LIBOR plus 4.00%, and the revolver is currently undrawn. There is a commitment fee, in respect of the unutilized commitments under the revolving facility, which is currently 0.50% per annum. There are also customary letter of credit fees. The New Credit Facilities also include customary repayment and prepayment provisions.

The New Credit Facilities contain customary affirmative and negative covenants and events of default, and the new revolving credit facility contains a financial covenant prohibiting the total net first lien leverage ratio from being greater than 4.00x (the “Financial Covenant”), which will be tested quarterly when the principal amount of all revolving loans, swingline loans and L/C obligations (in excess of $10.0 million) exceeds 30% of total commitments under the new revolving credit facility. Without the written consent of the required lenders, the Borrower is not permitted to incur loans under the new revolving credit facility unless it is in compliance with the Financial Covenant as of the last day of the most recently completed test period.

The information in Item 1.01 of this current report is incorporated by reference in this Item 1.02.
