Dear Ms. Clark
and Mr. Woody,

On
behalf of Magnachip Semiconductor Corporation (the “Company”), I submit our responses to the comments in your letter
dated October 28, 2022, related to the Company’s Form 10-K for the fiscal year ended December 31, 2021. Our responses to the
comments are set forth below. For ease of reference, the comments are also set forth in their entirety.

Form 10-K
for the Year Ended December 31, 2021

General

 1. Please
                                            tell us and revise to disclose the parties to which you refer to in the Form 10-K. In
                                            this regard, we note that you refer to a parent entity in terms of a terminated merger on
                                            page 45 but also refer to a parent entity in the U.S. that accounts for part of your tax
                                            expense on page 70. Your response and revised disclosure should name the parent entity that
                                            had to pay termination fees for the failed merger and clarify whether you have any further
                                            relationship with this entity subsequent to such attempted merger.

In
response to the Staff’s comment, the Company has revised its disclosure in its Form 10-Q for the quarter ended September 30,
2022 (the “Third Quarter 10-Q”) to clarify that the counterparty owing termination fees in connection with the failed
merger transaction, South Dearborn Limited (“Holdco”), is different from Magnachip Semiconductor Corporation (the
Company’s consolidated parent entity) and that, other than a remaining receivable for the

    Magnachip Semiconductor, 40F, Parc.1 Tower 2, 108, Yeoui-daero, Yeongdeungpo-gu, Seoul, South Korea 07335

termination
fee, the Company has no further relationship with Holdco. Please see page 22 of the Third Quarter 10-Q. Further, the Company will reflect
these changes in any future filings that are impacted by such disclosure, including in the 2022 annual report on Form 10-K.

Explanation
and Reconciliation of Non-U.S. GAAP Measures, page 48

 2. We
                                            refer to adjustment (i) on page 54. Please tell us and revise to further explain the nature
                                            of the material adjustment of $43.9 million for 2020 that eliminates the impact of the difference
                                            between GAAP and cash tax expense.

The
Company respectfully advises the Staff that, as a supplement to our financial results presented in accordance with GAAP, we present adjusted
net income/(loss) by adjusting income from continuing operations to eliminate the impact of a number of non-cash expenses and other items
that may be either one-time or recurring, which we do not consider to be indicative of our core ongoing operating performance. We believe
adjusted net income/(loss) provides useful information to investors in evaluating our core operating results over multiple periods.

The
adjustment of $43.9 million recorded for the fiscal year ended December 31, 2020 represented the release of valuation allowances computed
in accordance with GAAP, based on the evaluation of the recoverability of the related deferred tax assets in future years when such assessment
was made.

As
the determination of the release of valuation allowances reflected our expectation of, and assumptions as to, future operating results,
estimated future taxable income and applicable tax laws, and as it was deemed not to be indicative of our core operating performance,
we believed our performance results for the year ended December 31, 2020 would be more usefully compared with the prior periods if we
adjusted for the release of valuation allowances established against deferred tax assets.

However,
we acknowledge the Staff’s comment and have determined that, in future filings and earnings presentations, we will exclude changes
in our valuation allowance as a non-GAAP adjustment.

you have any questions, please do not hesitate to contact the undersigned by telephone at +82 2 6903 3053 or by email at shinyoung.park@magnachip.com.

File No. 001-34791

 Dear Mr. James:

MagnaChip Semiconductor Corporation (the “Company”) provides the following information in response to the comments contained
in the correspondence of the staff (the “Staff”) of the U.S. Securities and Exchange Commission, dated August 30, 2017, relating to the aforementioned Form 10-K. For reference purposes, the text of your letter dated
August 30, 2017, has been reproduced herein (in bold), with the Company’s response following such text. Unless the context otherwise requires, references to “MagnaChip,” “our,” “us,” or “we” mean
MagnaChip Semiconductor Corporation on a consolidated basis with its wholly owned subsidiaries.

 Form 10-K for the Fiscal Year Ended December 31,
2016

 Consolidated Financial Statements

 Note
4. Inventory, page 96

1.
We note your response to comment 1. In future periods in which you present the roll-forward, revise the table to separately show the gross amounts of inventory impairment charges recorded pursuant to ASC 330-10-35-2
in each period. Further, revise the inventory discussion in the Critical Accounting Policies and Estimates section of Management’s Discussion and Analysis to quantify the impairment charges recorded in each period. When material in future
periods, revise your Gross Profit discussions on pages 61 and 66 to disclose the impact of the sale of previously impaired inventory on gross margins. Refer to Item 303(a)(3) of Regulation S-K and Section V of SEC Release 33-3850.

 Response: The Company respectfully acknowledges the Staff’s comment and in future filings in which the Company presents the
roll-forward table, the Company will show separately the gross amount of inventory reserve charged to cost of sales and the reduction of reserve for the sale of previously reserved inventory in each period.

In addition, in future filings where applicable the Company will revise the inventory discussion in the Critical Accounting Policies and Estimates section of
Management’s Discussion and Analysis to quantify the impairment charges recorded in each period. The Company’s proposed disclosure based on its 2016 Form 10-K is as follows (added language is underlined):

 MagnaChip
Semiconductor, Ltd., 215, Daesin-ro, Heungdeok-gu, Cheongju-si, Chungcheongbuk-do, 28429, Republic of Korea

 “Inventories

Inventories are stated at the lower of cost or market, using the average cost method, which approximates the first in, first
out method (“FIFO”). If net realized value is less than cost at the balance sheet date, the carrying amount is reduced to the realizable value, and the difference is recognized as a loss on valuation of inventories within cost of sales.
Inventory reserves are established when conditions indicate that the net realizable value is less than costs due to physical deterioration, obsolescence, changes in price levels, or other causes based on individual facts and circumstances. We
evaluate the sufficiency of inventory reserves and take into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product
age and other factors. Reserves are also established for excess inventory based on our current inventory levels and projected demand and our ability to sell those specific products in excess of six months of projected for
each specific product. Situations that could cause these inventory reserves include a decline in business and economic conditions, decline in consumer confidence caused by changes in market conditions, sudden and significant decline in
demand for our products, inventory obsolescence because of rapidly changing technology and consumer requirements, or failure to estimate end customer demand properly. A reduction of these inventory reserves may be recorded if previously reserved
items are subsequently sold as a result of unexpected changes to certain aforementioned situations.

 The gross
amount of inventory reserves charged to cost of sales totaled $7,646 thousand, $13,635 thousand and $12,938 thousand in the fiscal years ended December 31, 2016, 2015 and 2014, respectively. The new cost base related to the sale of inventory
that was previously written down totaled $4,985 thousand, $13,932 thousand and $12,055 thousand in the fiscal years ended December 31, 2016, 2015 and 2014, respectively.

In addition, a As prescribed in ASC 330, “Inventory”, once a reserve is established for a
particular item based on our assessment as described above, it is maintained until the related item is sold or scrapped as a new cost basis has been established that cannot subsequently be marked up. In addition, the cost of inventories
is determined based on the normal capacity of each fabrication facility. In case the capacity utilization is lower than a certain level that management believes to be normal, the fixed overhead costs per production unit which exceed those under
normal capacity are charged to cost of sales rather than capitalized as inventories.”

 The Company also intends to include the foregoing disclosure
in its financial statements notes in future Form 10-K filings where applicable. The Company also respectfully acknowledges the Staff’s comment and in applicable future filings the Company will disclose the impact of the sale of previously
impaired inventory on gross margins if determined to be material.

Dear Mr. James:

 MagnaChip Semiconductor
Corporation (the “Company”) provides the following information in response to the comments contained in the correspondence of the staff (the “Staff”) of the U.S. Securities and Exchange Commission, dated
August 2, 2017, relating to the aforementioned Form 10-K. For reference purposes, the text of your letter dated August 2, 2017, has been reproduced herein (in bold), with the Company’s response following such text. Unless the context
otherwise requires, references to “MagnaChip,” “our,” “us,” or “we” mean MagnaChip Semiconductor Corporation on a consolidated basis with its wholly owned subsidiaries.

Form 10-K for the Fiscal Year Ended December 31, 2016

Consolidated Financial Statements

 Note 4. Inventory,
page 96

1.
We note that you establish a reserve for inventory and present a roll-forward in the second table on page 96. Please address the following:

•

Tell us what the reduction of $297 thousand presented as a ‘change in reserve’ in Fiscal 2015 represents.

•

Tell us whether the ‘change in reserve’ caption is a net amount for each period presented in the table and if so, provide us with the gross amount of impairment charges recorded pursuant to ASC 330-10-35-2
and the gross amounts of any recoveries or other items that reduced the caption amount for each period.

•

Explain to us how your accounting for impaired inventory complies with ASC 330-10-35-14 and SAB Topic 5.BB.

Response: The Company respectfully informs the Staff that the reduction of $297 thousand presented as a ‘change in reserve’ in the fiscal
year ended December 31, 2015 represents a net change in reserve attributable to a reduction of reserves offset by an addition to inventory reserves established in the same period. The reduction of reserves was recorded in connection with
previously reserved items that were sold during the period as a result of an unexpected increase in customer demand. The reduction of reserves did not cause any inventory to be written up as of December 31, 2015.

 MagnaChip
Semiconductor, Ltd., 215, Daesin-ro, Heungdeok-gu, Cheongju-si, Chungcheongbuk-do, 28429, Republic of Korea

 The following table presents the gross amount of inventory reserve charged to cost of sales, recorded pursuant to
ASC 330-10-35-2, and the reduction of inventory reserve for the sale of previously reserved inventory for the years ended December 31, 2016, 2015 and 2014 (in thousands):

 The Company evaluates the sufficiency of inventory reserves in accordance with ASC 330-10-35-2 and takes into consideration
historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product age and other factors. As a result, the Company’s inventory reserves are
established when conditions indicate that the net realizable value is less than cost due to physical deterioration, obsolescence, changes in price levels, or other causes based on individual facts and circumstances. Reserves are also established for
excess inventory based on the Company’s current inventory levels and projected demand and the Company’s ability to sell those specific products. Situations that could cause these inventory reserves include changes in business and economic
conditions, changes in consumer confidence caused by changes in market conditions, sudden and significant decreases in demand for the Company’s products, inventory obsolescence because of rapidly changing technology and consumer requirements,
or failure to estimate end customer demand properly.

 In accordance with ASC 330-10-35-14 and SAB Topic 5.BB, once a reserve is established for a
particular item based on the Company’s assessment as described above, it is maintained until the related item is sold or scrapped as a new cost basis has been established that cannot subsequently be marked up. In tracking the new cost basis for
impaired inventory, the Company retains both the original cost and the aggregate of all write-downs (i.e. the inventory reserve) in the Company’s accounting records. When previously written down inventory is sold or scrapped, the reserve
established for that inventory is reversed in the same period. As a result, the new cost basis is appropriately matched to the sale or scrap of the impaired inventory.

 Form 10-K for Fiscal Year Ended
December 31, 2014

 Filed May 28, 2015

File No. 1-34791

 Dear
Ms. Blye:

 MagnaChip Semiconductor Corporation (including its subsidiaries, the “Company”) provides the following
information in response to the comments contained in the correspondence of the staff (the “Staff”) of the U.S. Securities and Exchange Commission (the “Commission”), dated August 7, 2015 relating to the
aforementioned Form 10-K (the “Form 10-K”). For reference purposes, the text of your letter dated August 7, 2015 has been reproduced herein (in bold), with the Company’s response below each numbered comment. Unless the
context otherwise requires, references to “MagnaChip,” “our,” “us,” or “we” mean MagnaChip Semiconductor Corporation on a consolidated basis with its wholly owned subsidiaries. The Company acknowledges that:

•

the Company is responsible for the adequacy and accuracy of the disclosure in the filing;

•

Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the filing; and

•

the Company may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Form 10-K for the Fiscal Year Ended December 31, 2014

General

1.
You state on pages 13 and 22 of the 10-K that your customer Samsung Display Corporation accounted for more than 11.4% of your net sales for the year ending December 31, 2014. The Samsung Electronics (Samsung)
2014 Annual Report states that Samsung Display is a subsidiary of Samsung. The Samsung website indicates that Samsung has a store in Sudan and that Samsung televisions are available in Syria. We also are aware of a 2013 news article that refers to a
Samsung license and a Samsung franchise in Syria.

 Sudan and Syria are designated by the Department of State as state
sponsors of terrorism, and are subject to U.S. economic sanctions and export controls. Please describe to us the

 MagnaChip Semiconductor,
Ltd., 424, Teheran-ro, Gangnam-Gu, Seoul 135-738, Republic of Korea

nature and extent of your past, current, and anticipated contacts with Sudan and Syria, if any, whether through subsidiaries, affiliates, distributors, customers, joint ventures or other
direct or indirect arrangements. You should describe any services, products, information or technology you have provided to Sudan or Syria, directly or indirectly, and any agreements, commercial arrangements, or other contacts you have had with the
governments of those countries or entities they control.

 Response: We advise the Staff that the Company has not during the
period covered by our Form 10-K, and does not currently provide, and has no future plans to provide, any services, products, information or technologies to Sudan or Syria, their governments or entities they control. The Company has not entered into
any agreements or arrangements with Sudan or Syria and has no future plans to enter into any such agreements or arrangements. Moreover, the Company does not maintain any offices or other facilities in Sudan or Syria, has no employees in either of
those countries, and has no assets or liabilities associated with activities in either of those countries.

 The Company has not shipped any
of the products that the Company has sold to Samsung Display Co., Ltd. (“Samsung”) to Sudan or Syria, and the Company’s sales to Samsung were made in compliance with applicable export control and economic sanctions regulations.
The Company has no knowledge of or any basis to believe that the Company’s products were, or will in the future be, incorporated into Samsung products sold, either directly or indirectly, in Sudan or Syria. Samsung has not provided the Company
with information sufficient for the Company to reasonably determine sales of Samsung products on a geographic basis. Furthermore, the Company has no actual control over where Samsung sells its products.

The Company has export control and economic sanctions policies and procedures in place and is committed to compliance with these laws. The
Company’s export compliance procedures include training for key personnel and procedures for screening customer agreements. In addition, the Company has a Code of Business Conduct and Ethics that applies to all Company employees wherever they
are located or doing business, and which sets forth the Company’s policy that all Company directors, officers, employees, agents, and contractors must comply with all applicable laws, regulations, rules, and regulatory orders of the cities,
states, and countries in which the Company operates and accordingly, all Company directors, officers, and employees must comply with the laws, regulations, rules, and regulatory orders of the United States, including the Foreign Corrupt Practices
Act and the U.S. Export Control Act, in addition to applicable local laws in the Republic of Korea and elsewhere.

2.
Please discuss the materiality of any contacts with Sudan and Syria you describe in response to the comment above, and whether those contacts constitute a material investment risk for your security holders. You
should address materiality in quantitative terms, including the approximate dollar amounts of any associated revenues, assets, and liabilities for the last three fiscal years and the subsequent interim period. Also, address materiality in terms of
qualitative factors that a reasonable investor would deem important in making an investment decision, including the potential impact of corporate activities upon a company’s reputation and share value. Various state and municipal governments,
universities, and other investors have proposed or adopted divestment or similar initiatives regarding investment in companies that do business with U.S.-designated state sponsors of terrorism. You should address the potential impact of the investor
sentiment evidenced by such actions directed toward companies that have operations associated with Sudan and Syria.

 2

 Response: As indicated in our response to Comment No. 1 above, the Company has not
had any contacts with Sudan or Syria. Therefore, the Company has not had any revenue, assets and liabilities associated with Sudan or Syria for the last three fiscal years and the subsequent interim period.

If you have any questions regarding our responses, please feel free to contact me by telephone at (82) 2-6903-3073 or by facsimile at
(82) 2-6903-3898, or Stuart Ogg of Jones Day, outside counsel to the Company, by telephone at (213) 243-2365 or by facsimile at (213) 243-2539.

 Registration Statement on Form S-4 (No.
333-191372)

 Ladies and Gentlemen:

MagnaChip Semiconductor Corporation, a Delaware corporation (the “Company”), is submitting this letter in connection with its
Registration Statement on Form S-4 relating to the offer by the Company to exchange (the “Exchange Offer”) its 6.625% Senior Notes due 2021 (the “Exchange Notes”) for an equal principal amount of its 6.625% Senior
Notes due 2021 outstanding on the date hereof (the “Original Notes”). On July 18, 2013, the Company issued $225,000,000 aggregate principal amount of the Original Notes. All of the Original Notes are outstanding on the date
hereof.

 In accordance with the Commission’s position set forth in Exxon Capital Holdings Corporation (available May 13, 1988)
and its progeny, the Company makes the following representations to the Commission:

(1)
The Company has not entered into any arrangement or understanding with any person to distribute the Exchange Notes to be received in the Exchange Offer and, to the best of the Company’s information and belief, each
person participating in the Exchange Offer is acquiring the Exchange Notes in its ordinary course of business and has no arrangement or understanding with any person to participate in the distribution of the Exchange Notes to be received in the
Exchange Offer.

(2)
The Company will make each participant in the Exchange Offer aware (through the Exchange Offer prospectus or otherwise) that if such person is participating in the Exchange Offer for the purpose of distributing the
Exchange Notes to be acquired in the Exchange Offer, such person (a) cannot rely on the position enunciated in Exxon Capital Holdings Corporation or interpretive letters to similar effect and (b) must comply with the registration and
prospectus delivery requirements of the Securities Act of 1933 (the “Securities Act”) in connection with a secondary resale transaction. The Company acknowledges that such a secondary resale transaction by such person participating in the
Exchange Offer for the purpose of distributing the Exchange Notes should be covered by an effective registration statement containing the selling stockholder information required by Item 507 of Regulation S-K promulgated under the Securities
Act.

(3)
The Company will include in the transmittal letter, or similar documentation to be executed by the exchange offeree in order to participate in the Exchange Offer, representations to the effect that (a) the exchange
offeree is acquiring the Exchange Notes in its ordinary course of business, (b) by accepting the Exchange Offer, the exchange offeree represents to the Company that it is not engaged in, does not intend to engage in and does not have an
arrangement or understanding with any person to participate in a distribution of the Exchange Notes, and (c) the exchange offeree is not an affiliate of the Company.

(4)
With respect to any broker-dealer that participates in the Exchange Offer with respect to Original Notes acquired for its own account as a result of market-making activities or other trading activities, the Company will
include in the transmittal letter, or similar documentation to be executed by the exchange offeree in order to participate in the Exchange Offer, a representation that it will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of Exchange Notes received in respect of such Original Notes pursuant to the Exchange Offer.

 The
Company further represents that, with respect to any broker-dealer that participates in the Exchange Offer with respect to Original Notes acquired for its own account as a result of market-making activities or other trading activities, each such
broker-dealer must confirm that it has not entered into any arrangement or understanding with the Company or an affiliate of the Company to distribute the Exchange Notes. Additionally, the Company will make each person participating in the Exchange
Offer aware that any broker-dealer who holds Original Notes acquired for its own account as a result of market-making activities or other trading activities, and who receives Exchange Notes in exchange for such Original Notes pursuant to the
Exchange Offer, may be a statutory underwriter.

 Please contact the undersigned at (408) 625-5999, Micheal Reagan at
(650) 687-4147 or Stuart Ogg at (213) 243-2365, if you have any questions concerning the filing.

 Form 10-K for the Fiscal Year Ended December 31, 2011 (the “2011 10-K”)

 File No. 001-34791

 Dear Mr. Vaughn:

MagnaChip Semiconductor Corporation (the “Company”) provides the following information in response to the comments
contained in the correspondence of the staff (the “Staff”) of the U.S. Securities and Exchange Commission (the “Commission”), dated September 28, 2012, relating to the 2011 10-K. For reference purposes, the
text of your letter dated September 28, 2012 has been reproduced herein (in bold), with the Company’s response below each numbered comment. The Company acknowledges that:

•

 the Company is responsible for the adequacy and accuracy of the disclosure in the filing;

•

 Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the
filing; and

•

 the Company may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of
the United States.

 Management Discussion and Analysis of Financial Condition and Results of Operations, page 45; Results
of Operations, page 55

1.
We note you conduct significant operations outside your home country in functional currencies that differ from your reporting currency. Please tell us any material
effects of changes in currency exchange rates on reported revenues and costs as well as business practices and plans. Refer to Item 303(A)(3) of Regulation S-K and Financial Reporting Codification 501.09.b.

Response: A substantial portion of the Company’s operations relates to the Company’s Korean subsidiary, whose functional
currency is the Korean won. Accordingly, changes in the exchange rate of the U.S. dollar to the Korean won have the most significant effect on the Company’s revenues and costs.

 For the year ended December 31, 2011, over 20% of consolidated revenues and
approximately 70% of total costs were denominated in Korean won. The average exchange rate of the U S. dollar to the Korean won in 2010 was 1,157.9. This compares to 1,108.8 in 2011, a 4.2% decrease from 2010. This change in the exchange rate
resulted in a favorable impact of $7.8 million to reported revenues and an unfavorable impact of $20.8 million to expenses and costs of sales in 2011.

 To mitigate the impact of depreciation or appreciation in the U.S. dollar related to the Korean won, the Company’s Korean subsidiary entered into option, forward and zero cost collar contracts. The
Company pursues a hedge of 70 to 75% of net cash inflows from revenues and outflows from expenses denominated in Korean won. The effective portion of the derivative transactions reported under ASC 815, “Derivatives and Hedging,” in the
consolidated statement of operation for the year ended December 31, 2011 was $11.5 million. Combined with hedging transactions, the changes in exchange rates in 2011 resulted in a net unfavorable impact of $1.5 million to the Company’s
operating income.

 Relating to the impact of foreign currency exchange rates and corresponding hedging transactions, the
Company made disclosures in several locations in its 2011 10-K. Please refer to “Part I: Item 1. Risk Factors,” “Part I: Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
— Factors Affecting our Results of Operations,” “Part I: Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates,” and “Part
I: Item 7A. Quantitative and Qualitative Disclosures about Market Risk — Foreign Currency Exposures.” Given the fact that the Company’s Korean subsidiary put an active hedging process in place to mitigate the impact of U.S.
dollar depreciation or appreciation resulting in an effectively mitigated net impact of $1.5 million on operating income, the Company believes that the current disclosure satisfies Item 303(A)(3) of Regulation S-K and Financial Reporting
Codification 501.09.b.

 Notes to Consolidated Financial Statements, page 92; Note 9. Inventories, page 106

2.
Please explain to us the “change in reserve” of $2,997 in the year ended December 31, 2011. Tell us how your accounting complies with SAT Topic 5.BB,
which states that a write-down of inventory to the lower of cost or market creates a new cost basis that subsequently cannot be marked up based on changes in underlying facts and circumstances.

Response: The Company understands that an inventory reserve recorded at the close of a fiscal period creates a new cost basis that
subsequently cannot be marked up or reversed based on changes in underlying facts and circumstances pursuant to SAB Topic 5.BB. In respect to the “change” in the reserve balance of $3.0 million during the year ended December 31, 2011,
the Company respectfully informs the Staff that these changes in reserve represent the movement in the notional reserve due to new losses recognized and inventory sold during the period. These changes in inventory reserve do not include any reversal
of inventory reserve recorded at the close of prior fiscal period ends due to changes in facts and circumstances.

3.
Further to the above, if material, please revise future filings to quantify how changes in the inventory valuation allowances, including sales of previously written
down inventory, impact your gross margins.

 Response: The Company acknowledges the Staff’s
comment and will evaluate future filings for disclosure in accordance with such comment if determined to be material. The change in reserve in 2011 is not material compared to the inventory balance.

 Note 30—Condensed Consolidated Financial Statements, page 130

4.
We note your disclosure here that the guarantees are full and unconditional, subject to certain customary release provisions. Please explain to us in greater detail
the nature of the customary release provisions you are referring to. Explain how you evaluated these release provisions and how full and unconditional guarantee meets the definition under Rule 3-10(h) of Regulation S-X in light of the customary
release provisions disclosed.

 Response: The indenture dated as of April 9, 2010 (the
“Indenture”) governing the Company’s 10.500% Senior Notes due 2018 (the “Senior Notes”) contains customary release provisions for the guarantors under the Indenture (the “Guarantors”) that are
typical of substantially all senior note indentures of this type. These include (i) the sale or other disposition of the capital stock of a Guarantor, or all or substantially all of its assets, to a third party, so long as the proceeds of such
sale are used in accordance with the “Asset Sale” and other covenants of the Indenture; (ii) the declaration of such Guarantor as an “Unrestricted Subsidiary” under the Indenture; and (iii) upon legal defeasance,
covenant defeasance or in accordance with the satisfaction and discharge provisions of the Indenture.

 Pursuant to the guidance
set forth in Section 2510.5 of the Financial Reporting Manual (the “Manual”) prepared by the Staff of the Division of Corporation Finance, each of these automatic release provisions falls within the category of customary
circumstances deemed acceptable to meet the “full and unconditional” provision of Rule 3-10((h)(2) of Regulation S-X (See Section 2510.5, bullets 1, 2 and 4). The Indenture contains no other release provisions for Guarantors, and the
Senior Note guarantees of the Guarantors are otherwise full and unconditional consistent with the definition of Rule 3-10(h)(2) of Regulation S-X and as described in Section 2510.4 of the Manual.

If you have any questions regarding our responses, please feel free to contact me by telephone at 82-2-6903-3073 or by facsimile at

Amendment No. 8 to Registration Statement on Form S-1

 Filed February 1, 2011

 File No. 333-165467

Dear Mr. Buchmiller:

This letter is submitted on behalf of MagnaChip Semiconductor LLC (the “Company”) to the staff of the Division of
Corporation Finance (the “Staff”) of the Securities and Exchange Commission (the “SEC”) to supplement our letter to the Staff dated February 1, 2011 regarding the filing of Amendment No. 8 to the
Company’s Registration Statement on Form S-1 filed February 1, 2011 under Registration No. 333-165467 (the “Registration Statement”).

 In order to provide the Staff with additional information for its review of Amendment No. 8 to the Registration Statement, the Company supplementally advises the Staff that the Company and the
underwriters presently estimate that the public offering price for the Company’s common stock (which will be sold in the form of depositary shares (the “Shares”)) will be $16.50 per Share, which is the midpoint of a preliminary range
of $15.00 to $18.00 per Share. This preliminary range may differ from the ultimate range used in the Company’s initial public offering (the “Offering”). The Company advises the Staff that the final range to be included in an
amendment to the Registration Statement will include a price range of no more than $2.00 or ten percent (10%) of the low end of the range unless otherwise approved by the Staff. The preliminary price range is based upon the outstanding common
units of the Company being converted into common stock in connection with the Company’s conversion to a corporation at the ratio of one (1) share of common stock for every eight (8) common units.

The Company and the underwriters anticipate that up to 90% of the Shares sold in the Offering will be sold by the selling stockholders.
However, the final level of participation in the Offering by selling stockholders has not yet been determined. The selling stockholders will participate in the offering on a pro rata basis based on the total number of shares desired to be sold by
each participating selling stockholder. Based on the total number of shares that selling stockholders have indicated a desire to sell in

the Offering, Avenue’s Shares will comprise 76.8% of the Shares to be sold by the selling stockholders. Assuming that 90% of the Shares in the Offering are sold by the selling stockholders,
Avenue’s shares will represent 69.1% of the total shares in the Offering.

 If you have any questions, please feel free to
contact the undersigned by telephone at 650-687-4147 (or by facsimile at 650-739-3900) or Stuart Ogg at 213-243-2365 (or by facsimile at 213-243-2539). Thank you for your cooperation and attention to this matter.

Registration Statement of Form S-4 (File No. 333-168516)

Statement be accelerated so that the Registration Statement, as then amended, will become effective under the Securities Act by 4:00 p.m. (Eastern Time) on Friday, October 15, 2010, or as soon thereafter as practicable.

The disclosure in the Registration Statement is the responsibility of the Issuers and the guarantors, listed on the Table of Additional
Registrants in the Registration Statement (the “Guarantors”). Each of the Issuers and the Guarantors acknowledge that staff comments or changes in response to staff comments in the disclosure in the Registration Statement may not be
asserted as a defense in any proceeding which may be brought by any person with respect to this matter. Each of the Issuers and the Guarantors also represent to the Commission that should the Commission or the staff acting pursuant to delegated
authority, declare the Registration Statement effective, it does not foreclose the Commission from taking any action with respect to the Registration Statement and each of the Issuers and the Guarantors represent that they will not assert this
action as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

 Each of the Issuers and the Guarantors further acknowledge that the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the Registration Statement effective does
not relieve the Issuers and the Guarantors from their full responsibility for the adequacy and accuracy of the disclosure in the Registration Statement.

 We have limited our review of your registra tion statement to those issues we have
addressed in our comments.  In some of our comments, we may ask you to provide us with
information so we may better understand your disclosure.
 Please respond to this letter by amending your registration statement and providing the
requested information.  Where you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your
response.
 After reviewing any amendment to your re gistration statement and the information you
provide in response to these comments, we may have additional comments.
 Resales of New Notes, page 213

 1. It appears you are registering the exchange of Senior Notes in re liance on our position
enunciated in Exxon Capital Holdings Cor p., SEC No-Action Letter (April 13, 1989).
See
 also Morgan Stanley & Co. Inc., SEC No-Act ion Letter (June 5, 1991) and Shearman
& Sterling, SEC No-Action Letter (July 2, 1993).  Accordingly, with the next
amendment, please provide us with a supplem ental letter stating th at you are registering
the exchange offer in reliance on our position contained in these le tters, identifying such
letters, and include the representations cont ained in the Morgan Stanley and Shearman &
Sterling no-action letters.
 2. We note from your disclosure on page 156 that Avenue purchased $35 million of the $250 million Senior Notes you issued and that Av enue is your affiliate.  Given that you
are registering the exchange of the entire $250 million Senior Note s, it appears that
Avenue intends on participating in that exchange.  If so, please tell us how such participation by Avenue is consistent with the no-action letters on which you intend to

Notwithstanding our comments, in the event you request acceleration of  the effective date

acknowledging that:

• should the Commission or the staff, acting purs uant to delegated authority, declare the
filing effective, it does not foreclose the Co mmission from taking any action with respect

• the action of the Commission or the staff, acting pursuant to delegated authority, in
declaring the filing effective, does not relieve the company from its full responsibility for
the adequacy and accuracy of the disclosure in the filing; and

• the company may not assert staff comments a nd the declaration of effectiveness as a
defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Please refer to Rules 460 and 461 regarding re quests for acceleration.  We will consider a
written request for acceleration of  the effective date of the regi stration statement as confirmation

Dear Mr. McFarland:

We have reviewed your filing and have the following comments.  Where
indicated, we think you should re vise your document in response to these comments.  If
you disagree, we will consider your explanation as to why our comment is inapplicable or
a revision is unnecessary.  Please be as deta iled as necessary in your explanation.  In
some of our comments, we may ask you to provi de us with information so we may better
understand your disclosure.  After reviewing th is information, we may raise additional
comments.
We welcome any questions you may have  about our comments or any other
aspect of our review.  Feel fr ee to call us at the telephone numbe rs listed at the end of this
letter.  Corporate Information, page 5

 1.      Please expand your revisions added in response to prior comment 2 to disclose that Avenue has the right to appoint a majority of your board of directors.

complete the blanks in your documen t, including the table on page 142.

 3.       Please expand your revisions added in res ponse to prior comment 11 to clarify
what “market conditions” and what about  your “capital structure” led you to
conduct the notes offering.  It is unclear how the reas ons you cite relate to your
decision to offer and sell the notes, given the “principal purpose” of the offering,
the terms of the notes as compared to your  term loan and the impact it had on the
amount of your debt outstanding.  Also, please clarify the rationale for the distribution to your unitholde rs given your indebtedness prior to the note offering
and your recent bankruptcy proceeding.
 Customers, page 113

 4. Please expand your revisions added in response to prior comment 13 to disclose the percentage of sales by your Display Solutions segment attributable to LG
Display.  See Item 101(c)(1)( vii) of Regulation S-K.
 Exhibit 1.1

 5. Please file an updated version of this e xhibit that reflects changes you make to
your registration statement.  We note, for example, the blank spaces in
Schedule II.  When you file that updated version, please also include all missing
or blank attachments, including Schedule IV(b), Annex I(a)-(d), Annex II and
Annex III.
 Exhibits 5.1 and 8.1

 6. The opinion you file pursuant to Item 601(b)(5) of Regulation S-K should not
assume any material facts underlying the opinion.  We note, for example, that
counsel appears to assume in each of the first three paragraphs that the conversion
of MagnaChip Semiconductor LLC into MagnaChip Semiconductor Corporation will occur.  Please file a revised opin ion prior to requesting acceleration of
effectiveness of the registration statement that does not assume that the corporate
conversion has taken place.
 7. With reference to the assumptions that appear in the last two sentence of the
second paragraph on page 1, it is inappropriate  to shift the burden of these factual
matters to investors when those matters  could be readily obtained through an
officers' certificate.  Please revise.
 8. With respect to the opinion expressed in  clause (iii) of th e last paragraph on
page 1, please file an opinion which also  opines that the Deposit Agreement is a
legal, binding obligation of the registrant .  Since the Depositary Shares are being
issued pursuant to the Deposit Agreement, and the Depositary is also a necessary

John McFarland, Esq.
c/o MagnaChip Semiconductor, Inc.
May 28, 2010 Page 3
co-party to that agreement, please also file an opinion of the appropriate counsel
that opines that the Deposit Agreemen t is a legal, binding obligation of the
Depositary, or provide us with an expl anation as to why such opinion is not
appropriate.
 9. Refer to the first paragraph on page 2.  The opinion you file pursuant to
Item 601(b)(8) of Regulation S-K must include counsel’s opinion regarding
material tax consequences.  Your curr ent opinion appears to only opine that
disclosure is an “accurate summary,” not th at the disclosure is counsel’s opinion.
Please file a revised opinion.  Ensure th at such opinion addresses each discussion
of the tax matters being opined upon.  We note, for example, that this exhibit does not include the tax discussion menti oned in the risk factor on page 33.
 10. In view of the statement that the opinion is rendered “as of the date hereof” and
disclaimer regarding subsequent changes to law or fact, please file a revised
opinion on the date you expect th is registration statement to be declared effective.
Alternatively, file a revised opinion without the disclaimer.

As appropriate, please amend your regist ration statement in response to these

responses to our comments and provides any requested information.  Detailed cover
letters greatly facilitate our review.  Please understand that we may have additional comments after reviewing your amendment and responses to our comments.
We urge all persons who are responsible for the accuracy and adequacy of the
disclosure in the filing to be certain that the filing includes all in formation required under
the Securities Act of 1933 and that they have  provided all information investors require

actions you mention “reduced [y]our costs and improved our margins,” given that your disclosure on pages 68 and 69 indi cates that your cost and margin
improvements relate to factors othe r than those you mention here.

purpose of that offering.  It is unclear from your disclosure why you replaced your
prior debt with the notes, pa rticularly since a primary purpose of that note offering
was to provide a distribution to your unit hol ders and that a signi ficant portion of

 Customers, page 97

 17.       Regarding your response to prior comment 50:

• It remains unclear from your disc losure whether the information you
present regarding sales to LG Display is on a consolidated basis or for a
single segment.  Please revise, and ensu re that your disclosure includes the
identity of each customer who accounts for more than 10% of the sales for each segment and whose loss would ma terially impact your business;

• If you continue to highlight your relationships with “leading innovators”
like Samsung and Sharp, as you do on page 86, and that Samsung and
Sharp account for a substantial porti on of your revenues, as you indicate
on page 84, then please tell us how you concluded that investors can
assess the relative signif icance of those customers without disclosure of
the specific percentage of sales attr ibutable to those customers; and

• Please clarify how the relationships you mention “were . . . adversely
impacted” by your reorganization proceedings.
 Directors and Executive Officers, page 99

 18.     We note your response to prior comment 54.  Refer to the last sentence of the
disclosure regarding the business experien ce of each of Messrs. Elkins, Klein and
Tan and revise to clarify, as appropriate, how those directors “have gained significant knowledge with respect to th e management of companies through their
investment in, and ownership of, numerous  companies in multiple industries” and
the experience they gained in “advising companies undergoing financial turnarounds,” including the sp ecific companies.  Also re vise to clarify which of
the directors you note has “substantial l ong-term experience investing in multi-
national semiconductor manufacturing companies” and how that investment experience relates to the significant knowle dge with respect to the management of
companies.
 19.       We note your revisions on page 100 in re sponse to prior comment 55; however,
the nature of Mr. Elkins’ management e xperience continues to be unclear.  For
example, do you mean he has 15 years of  portfolio management experience?

Also, please tell us, with a view toward disclosure, the nature of the portfolio
companies for whom Mr. Elkins served and serves as a director.  For example, are
these public companies?
 Board Composition, page 102

 20.       We note your revisions added in response to prior comment 57.  Please expand to
disclose how not having a majority of your board be “independent” satisfies the
exchange rules mentione d in your document.
 Assessment of Risk, page 103

 21.    Your disclosure implies that your board  conducted the review mentioned in your
response to prior comment 63 and concl uded that your compensation programs do
not encourage excessive risk taking.  Your  response to prior comment 63 states
that management conducted the review and reached that conclusion.  Please
reconcile.
 General Background, page 106

 22.      We reissue prior comment 64 with re spect to the “ranges” for overall
compensation mentioned in the second paragraph.  Please revise to clarify this “range” and how it relates to the “overall compensa tion” you pay to your named
executive officer.
 Base Salary, page 107

 23.    Please expand your revisions in response to prior comment 65 to clarify where the current base salaries of your named executive officers are in relation to the
median.
 24.       We note your revisions in response to prio r comment 66.  You refer here to a one-
time payment of 20% of monthly base sa lary, but note 1 on page 111 indicates the
payment was 30%.  Please reconcile.  Also, your disclosure here indicates that these payments are included in th e “Bonus” column, but note 1 on page 11
indicates that the payments are in the “Sal ary” column.  Please reconcile.  Ensure
that your revisions clearly identify th e amount of the payments you mention for
each named executive officer.

 25.      Please note that prior comment 67 was not  limited to your cash incentive program
for 2009.  Expand your response or revise  your disclosure accordingly.

John McFarland, Esq.
c/o Magnachip Semiconductor, Inc.
May 4, 2010 Page 6  26.    We note your revisions in response to  prior comments 68 and 72.  Given your
disclosure that the disc retionary incentive you paid to Mr. Hwang, Ms. Sakai and
Mr. McFarland was for the same purpose, please revise to cl arify why different
amounts were paid to those named executives.
 27.   Please expand your revisions to the last pa ragraph of this section to disclose
whether payments were made for the first fiscal quarter and, if so, the amounts of
those payments.
 Equity Compensation, page 109

 28.    We note your revisions in response to pr ior comment 70; however, it continues to
be unclear from your disclosure how you determined the relative proportion of
options and restricted unit granted to your named executives.  It is similarly
unclear how you determined the amounts of restricted units to  award to each
named executive.  We note the vague refe rence to providing an “embedded value”
but it is unclear what that value was or how it was determined.  Please revise.
 Summary Compensation Table, page 111

 29.    We note your response to prior comment 74.  If the “bonus” for Mr. Rowe was
fixed in amount, non-discreti onary and subject only to his continued employment,
it is unclear why it does not represent “ongoing base compensation.”  Similarly, if
the “bonus” you paid to Mr. Park mentione d in note 4 and in Exhibit 10.27 was
fixed, non-discretionary and subject only to his continued employment, it is
unclear why that payment is reflected in the “Bonus” column.  Please expand your response or revise, as appropriate.

the amount of the accrual resulting from the multiplier you note.

per unit paid in the offering you mention, a nd the effective pri ce per share paid by

commitment referenced in your disclosure.  Also, when you complete the blanks in your table, please ensure it is clear from your disclosure which offered shares
are registered for resale.  For example, if a selling stockholde r is offering all of
the shares related to your floating rate notes and a portion of th e shares related to
the offering you mention, pleas e make that clear.

 32.    Please ensure that the full scope of your related-party transac tions is clear from
your disclosure.  For example, it is unclear what amount Avenue received upon repayment of the senior secu red credit agreement.  It is similarly unclear what
amount each of your affiliate unitholders  received from the proceeds of your
senior note offering.  Please revise.
 33.      Please reconcile your response to prior comment 82 that the purpose of the offering is to allow all equity holders to  benefit with your disclosure on page 138
that the purpose is to allow only the selling stockholders  to benefit.
 Rule 144, page 144

 34.    Please note that prior comment 92 related to what extent, if any, your disclosure
addressed how the time periods in Rule 144 are impacted by the 45-day period mentioned in your disclosure.  For example, does the six month and one-year periods you mention include or exclud e those 45 days?  Please expand your
response accordingly and cite a ll authority on which you rely.
 Material U.S. Federal Income Tax Consequences, page 146

 35.    We your revisions in response to prior comments 89 and 93 and the repeated
statements as to what the depositary shares “should” represent, which appears to simply move the equivocal term that wa s mentioned in prior comment 89 to this
section.  If counsel is
 able to opine on a matter but doubt exists because of a lack
of relevant authority or ot herwise, you may use the term “should” to make it clear
that the opinion is subject to a degree of uncertainty.  In such cases, you should
explain why counsel cannot give a “will” opinion, describe the degree of uncertainty in the opinion, and provide risk factor and/or other appropriate
disclosure setting forth the risks to i nvestors.  If, in contrast, your counsel is not

able to opine on a material tax matter, please say so dire ctly, disclose why counsel
is not able to provide the opinion, and st ate the possible outcomes and risks to
investors of that tax consequence.  Wh ere you are unable to provide unequivocal
disclosure regarding the tax consequences  throughout this section, please revise
your disclosure accordingly.
 Underwriting, page 150

 36.     Refer to page 153.  Revise to clarify the amount of senior notes purchased by each entity you mention and disclose the regi stration and exchange rights mentioned on
page 141 and in Exhibit 4.4.  Also revise  to disclose the amounts those entities
received upon repayment of your senior secured credit facilities.

  File No. 333-165467

Dear Mr. McFarland:

We have reviewed your filing and have the following comments.  Where
indicated, we think you should re vise your document in response to these comments.  If
you disagree, we will consider your explanation as to why our comment is inapplicable or
a revision is unnecessary.  Please be as deta iled as necessary in your explanation.  In
some of our comments, we may ask you to provi de us with information so we may better
understand your disclosure.  After reviewing th is information, we may raise additional
comments.
Please understand that the purpose of our re view process is to assist you in your
compliance with the applicable disclosure  requirements and to  enhance the overall
disclosure in your filing.  We look forward to  working with you in these respects.  We
welcome any questions you may have about our comments or any other aspect of our review.  Feel free to call us at the telephone numbers listed at the end of this letter.
 Registration Statement cover page

1.       It appears from the disclosure in your  document, such as the disclosure on
pages 34 and II-2, that “MagnaChip Semic onductor LLC” is not the issuer of any
of the offered securities.  Therefore, it is unclear why that entity is listed here as
the registrant or how the signatures that appear on page II-8 correspond to the
requirements of Form S-1.  Please revise or advise.

April 9, 2010 Page 2  Fee Table

 2.       We note from your fee table that you app ear to be register ing the offering of
depositary shares.  From your disclosure  under “Description of Capital Stock”
beginning on page 125, it does not appear, however, that you are or will be authorized to issue “depositary shares ” under your certificate of incorporation.
Further, from your disclosure under “Des cription of Depositary Shares” beginning
on page 131, it appears that the depositary will be the issuer of the depositary
shares.  Please provide us with your anal ysis as to why the depositary should not
be identified as the issu er/registrant of the depositary shares in your current
registration statement, or in another appropriate registration statement which
registers the offering of the depositary sh ares.  In addition, we note from your
disclosure under “Legal Matters” on page 144 that you currently intend
MagnaChip’s counsel to opine as to the va lidity of the depositary shares.  In this
regard, please provide us with your analysis as to how your counsel will be able to opine as to the validity of securities you are not authorized to issue.
 3.       We understand from your disclosure on page  131 that at some future date the
depositary shares will be cancelled and th at the depositary wi ll then “credit” the
former holders of the depositary shares  with an equal number of shares of
MagnaChip’s common stock.  Please provide us  with your analysis as to how that
transaction will be registered  or exempt from registration.  In this regard, we note
that the issuer of the depositary shares appears to be the depositary and the shares of common stock will be i ssued by MagnaChip.  As such, it does not appear that
the transaction would qualify for exem ption under Section 3(a)(9) of the
Securities Act given the di versity of issuers.
 Prospectus cover page

 4.       Please confirm that any preliminary pros pectus you circulate will include all non-
Rule 430A information.  This includes the price range and related information
based on a bona fide estimate of the public  offering price within that range, and
other information that was left blank throughout the document.
 5.       The paragraph following the table refers to an option to purchase depositary
shares.  Note 1 to your fee table refers to an option to purchase common shares.
Please reconcile.
 6.       If you intend to delist your de positary shares in connection with the cancellation
of those securities, please state so  directly here and on page 131.

the same.  If so, please revise  to disclose that fact.
 17. We see that prior to the closing of this offering, MagnaChip Semiconductor LLC
will convert from a Delaware limited liability company to a Delaware corporation.  We also see that in conn ection with the corporate conversion, each
common unit of MagnaChip Semiconductor LLC will be converted into an undisclosed number of shares of co mmon stock of MagnaChip Semiconductor
Corporation.  In light of the referenced  pending conversion, please tell us how the
guidance at SAB Topic 4 (C) impacts you.  Als o, tell us if you plan to present pro
forma information as of the latest balan ce sheet date that reflects the referenced
changes in your capitalization at the e ffectiveness or the close of your IPO.
 18. Please briefly describe the nature of  Avenue and its affiliated funds.
 Risk Factors, page 16

 19.       Given your disclosure on pages 29 and 120, please tell us whether you will be a

could have “material adverse consequences” on you.
 Our ability to compete successfully. . ., page 25

 22.       Since you appear to do a si gnificant amount of business in China, disclose that
China is one of those countries that hi storically has not protected a company's
intellectual property rights to the sa me extent as the United States.
 If our Korean subsidiary is designated . . ., page 26

 23.       We note the risks you say are presented “if” your subsidiary is designated as a
regulated business.  Clarify why you do not  know whether your subsidiary is or
will be so designated and disclose whether you currently exceed the thresholds proposed by the Decree.
 You may be unable to enforce judgments obt ained in United States . . . , page 27

 24.       Disclose whether an investor would find it difficult:

• to enforce against you, your non-U.S. o fficers and directors, and your non-
U.S. subsidiaries U.S. court judgmen ts based upon the civil liabilities
provisions of the U.S. federal securities laws in a U.S., South Korean or other
foreign court; or

• to bring an original ac tion against you and the ab ove persons to enforce
liabilities under the U.S. federal securi ties laws in a South Korean or other
foreign court.

See Item 101(g) of Regulation S-K.
 Industry and Market Data, page 33

 25.       Please tell us whether all industry data you cite in your document is publicly
available.  Also tell us whether:

• you commissioned the preparation of such data;

John McFarland, Esq.
c/o Magnachip Semiconductor, Inc.
April 9, 2010 Page 6
• the sources of the data consented to your use of their data in this registration
statement; and

• how you confirmed that the data used in your registration statement reflects the most recent available information.  In this regard, the penultimate sentence of this section implies that you will not update the data you cite even if you
are aware the data is not the most recent and available.  If that is not correct,
please revise to eliminate that implication.
 Use of Proceeds, page 34

 26.       Expand to disclose how you intend to use the proceeds you may receive from
securities sold pursuant to the over-allotment option.
 27.       With a view toward clarified disclosure in this section, please tell us the amount
of proceeds that you will use to make paym ents to affiliates, whether through the
payments mentioned in the first bullet or the performance bonus mentioned on page 112 and in section 3.b.(ii) of Exhibit 10.27.  Ensure that the disclosure in an
appropriate section of your document fully discusses the transaction.  Refer to Item 404 of Regulation S-K.
 Dilution, page 36

 28.       Expand the paragraph following the first ta ble to clarify how the calculation you
mention would change, assuming the exerci se of the over-allotment option.  Also
expand the first and last paragraphs on pa ge 37 to explain how the numbers in the
last three columns of the tables would change, assuming exercise of the over-
allotment option.
 Selected Historical Consolidated Fi nancial and Operating Data, page 38

 29. We see that you present Adjusted EBITDA as part of your Supplemental Data and
we see your disclosure that you use Ad justed EBITDA to measure compliance
with certain covenants in your debt agreem ents. Please clarify for us if Adjusted
EBITDA, as calculated for purposes of  your debt covenants is the same
calculation as that provided on page 41.
 30. In this regard, please tell us why you excl uded the net foreign currency gain/(loss)
in your calculation of Adjusted EBIT DA. Please explain how much of this
adjustment relates to the cash impact of  foreign currency transaction gains or
losses. To the extent that this is not part of Adjusted EBITDA as calculated for purposes of your debt covenants, please tell us why you believe this exclusion is appropriate based upon the guidance in Item 10(e) of Regulation S-K and

Question 102.09 of the Staff’s Non-GAAP Financial Measures Compliance and Disclosure Interpretations dated January 15, 2010.
 31. We see that you also excluded net foreign currency gain/(loss) as part of your
calculation of Adjusted Net Income (Lo ss) and you indicate portions of this
amount relate to the cash impact of foreign currency transaction gains or losses.  As it appears that this is a perfor mance measure where certain amounts may
require cash settlement, please tell us how you determined that Adjusted Net
Income (Loss), as reported, is compliant with Item 10(e) of Regulation S-K.
 Management’s Discussion and Analysis . . ., page 52

 32. We refer to your disclosure in the thir d full paragraph on page 53.  Please expand
your disclosure to more clearly explai n why you believe your business does not
require “substantial investment in le ading edge process equipment” when,
consistent with Moore’s Law, the genera l industry trend in the sectors in which
you compete is to constantly move towards smaller geometry processes, such as 90 and 65, and then 45 nanometer geometry  process technolo gies, and towards
system on chip technologies (which comb ine several of the functionalities that
you offer of separate chip s on the same chip), in order to provide more
sophisticated products, with smaller foot prints and reduced energy consumption.
Since you offer manufacturing servic es and do not outsource your own
manufacturing, please include appropriate risk factor disclosure regarding the
costs that would be involved if you were  required to upgrade your equipment in
order to remain competitive and the risk s to your business, op erating results and
financial condition if your manufact uring equipment becomes obsolete.
 33. With reference to your captive manufact uring strategy, please disclose any known
trends on the positive or ne gative effects of this strategy on the gross profit
margins of your semiconductor products as compared to those of your competitors who are fabless.
 Recent Changes to Our Business, page 54

 34. We note that in beginning in the second half of 2008 you began to take steps to
focus your business strategy, enhance your operating efficiency and improve your
cash flow and profitability.  Please provide  your potential investors with a more
meaningful description of your business improvement plan and its purpose, what
has been accomplished to date, what remains to be achieved, including any
obstacles that you expect to encounter, the expected date by which the plan will
be complete and the overall effect of th e plan on your business, operating results
and financial condition.  Please see Inte rpretative Release No. 33-8350, available
