Subsequent Events [Text Block]	20. Subsequent Event On April 29, 2014, Cirrus Logic announced that Cirrus Logic and board of directors of Wolfson Microelectronics plc, a public limited company incorporated in Scotland (“Wolfson”), had agreed on the terms of a recommended cash offer of £2.35 per share (the “Offer”) to be made by Cirrus Logic for the acquisition of the entire issued and to be issued share capital of Wolfson (the “Acquisition”). The Offer values the entire issued and to be issued share capital of Wolfson at approximately £291 million (approximately $488 million based on a U.S. dollar to pound sterling exchange rate of 1.68) (the “Offer Consideration”), and implies an enterprise value of Wolfson of approximately £278 million (approximately $467 million based on a U.S. dollar to pound sterling exchange rate of 1.68). As a result of this agreement, we entered into a nine-month foreign currency hedging contract, which is expected to mitigate the risks of foreign currency fluctuation related to this transaction. The Acquisition, if approved, is expected to strengthen Cirrus Logic’s ability to expand its customer base with highly differentiated, end-to-end audio solutions for portable audio applications. The Acquisition will be financed by a combination of existing cash on Cirrus Logic’s balance sheet and $225 million in debt funding from Wells Fargo Bank, National Association. The Acquisition is expected to close in the second half of calendar year 2014. Cirrus Logic entered into a credit agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association as administrative agent and lender, on April 29, 2014, in connection with the Acquisition. The Credit Agreement provides for a $225 million senior secured revolving credit facility (the “Credit Facility”). The Credit Facility may be used for, among other things, payment of the Offer Consideration in connection with the deal. The Credit Facility matures on the earliest to occur of (a) January 23, 2015, (b) the date of termination of the Commitments as a result of a permanent reduction of all of the Commitments (as defined therein) by Cirrus Logic or (c) the date of termination of the Commitments as a result of an event of default (such date, the “Maturity Date”). Cirrus Logic must repay the outstanding principal amount of all borrowings, together with all accrued but unpaid interest thereon, on the Maturity Date. The Credit Facility is required to be guaranteed by all of Cirrus Logic’s material domestic subsidiaries (the “Subsidiary Guarantors”). The Credit Facility is secured by substantially all of the assets of Cirrus Logic and any Subsidiary Guarantors, except for certain excluded assets. Borrowings under the Credit Facility may, at our election, bear interest at either (a) a base rate plus the applicable margin (“Base Rate Loans”) or (b) a LIBOR rate plus the applicable margin (“LIBOR Rate Loans”). The applicable margin ranges from 0% to .25% per annum for Base Rate Loans and 1.75% to 2.25% per annum for LIBOR Rate Loans based on the Leverage Ratio (as defined below). A Commitment Fee accrues at a rate per annum ranging from 0.30% to 0.40% (based on the Leverage Ratio) on the average daily unused portion of the Commitment of the Lenders. Certain representations and warranties are required under the Credit Agreement, and the Company must be in compliance with specified financial covenants, including the ratio of consolidated funded indebtedness to consolidated EBITDA for the prior four consecutive quarters must not be greater than 1.75 to 1.00 (the “Leverage Ratio”) and the sum of cash and cash equivalents of Cirrus Logic and its subsidiaries on a consolidated basis must not be less than $75 million.
