PART III
NARRATIVE
State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR or the transition report or portion thereof, could not be filed within the prescribed time period.
MagnaChip Semiconductor Corporation (the “Company”) has determined that it is unable to file its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2015 (the “Q1 2015 Form 10-Q”) within the prescribed time period without unreasonable effort or expense for the reasons described below:
The principal reason for this delay is the time, effort, and resources involved in preparing the previously announced restatement of certain of the Company’s financial statements and the time and resources that were required to complete the Company’s 2013 Annual Report on Form 10-K (the “2013 Form 10-K”), which included its restated annual financial statements for the years ended December 31, 2012 and 2011, as well as the Company’s 2014 Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2014, June 30, 2014 and September 30, 2014, which included the corresponding comparative restated financial statements for the quarterly periods ended March 31, 2013, June 30, 2013 and September 30, 2013, respectively (the “2014 Form 10-Qs”), each of which was filed with the Securities and Exchange Commission (the “SEC”) on February 12, 2015.
Because of the time and resources required to complete the 2013 Form 10-K and 2014 Form 10-Qs, the Company was substantially delayed in initiating its 2014 fiscal year end close. The Company is currently in the process of completing the preparation of its financial statements for its fiscal year ended December 31, 2014 and its Annual Report on Form 10-K for such period (the “2014 Form 10-K”).
As a result of the delay in the preparation of the Company’s 2014 financial statements and 2014 Form 10-K, the Company has also been delayed in the preparation of its first quarter 2015 financial statements and its Q1 2015 Form 10-Q.
The Company currently anticipates filing its 2014 Form 10-K in the second quarter of 2015 and filing its Q1 2015 Form 10-Q within two weeks from the filing of the 2014 Form 10-K; however, the Company cannot provide any assurances at this time that it will be able to meet its expected timing.
As a result of the foregoing, the Company will not be in a position to complete the preparation of its first quarter 2015 financial statements and file its Q1 2015 Form 10-Q within the 5-day extension period provided in Rule 12b-25(b).
Safe Harbor for Forward-Looking Statements
Information in this Form 12b-25 report regarding the Company’s forecasts, business outlook, expectations and beliefs are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks and uncertainties. All forward-looking statements included in this report, including expectations about the timing, form and content of the Company’s 2014 Form 10-K, Q1 2015 Form 10-Q and other SEC filings are based upon information available to the Company as of the date of this report, which may change, and the Company assumes no obligation to update any such forward-looking statements. These statements are not guarantees of future performance and actual results could differ materially from the Company’s current expectations. Factors that could cause or contribute to such differences include the impact of the internal investigation, restatement and delayed SEC report filings on the Company’s business, including its customers, suppliers, counterparties, and under the Company’s debt instruments; the extent of any material weakness or significant deficiencies in the Company’s internal control over financial reporting; the outcome of litigation and other claims or proceedings arising out of the restatement; and other risks and uncertainties of the Company’s business detailed from time to time in the Company’s filings with the SEC, including without limitation those described under the heading “Risk Factors” in the Company’s Annual Report on Form 10-K filed on February 12, 2015, as well as subsequent registration statements, amendments or other reports that the Company may file from time to time with the SEC and/or make available on its website. The Company assumes no obligation and does not intend to update the forward-looking statements provided, whether as a result of new information, future events or otherwise.
