ITEM 3.
LEGAL PROCEEDINGS During the second quarter of 2007, we reversed the remaining $1.2 million reserve we had established relating to the possible theft of our customers’ credit and debit card data.
See Note 13 to the Consolidated Financial Statements included in Item 8, “Financial Statements and Supplementary Data.
” A lawsuit has been filed against us in California alleging violations of state laws regarding employee record- keeping, meal and rest breaks, payment of overtime and related practices with respect to our employees.
The case seeks damages, penalties and attorney’s fees on behalf of a purported class of our present and former employees.
We are currently investigating these claims, and although we have various defenses, it is not possible at this time to reasonably estimate the outcome of or any potential liability from this case.
We’re involved in various other claims and legal actions that arise in the ordinary course of business.
We do not believe that the ultimate resolution of these actions will have a material adverse effect on our financial position, results of operations, liquidity or capital resources.
However, a significant increase in the number of these claims, or one or more successful claims under which we incur greater liabilities than we currently anticipate could materially and adversely affect our business, financial condition, results of operation and cash flows.
ITEM 4.
SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS There were no matters submitted to a vote of our security holders through solicitation of proxies or otherwise, during the fourth quarter of our fiscal year ended December 31, 2007.

The Company has not paid dividends to date and does not plan to pay dividends in the near future.
The riskfree interest rate is based upon U. S.  Treasury rates for instruments with similar terms.
The volatility assumption was based on our historical data and implied volatility, and the expected life assumptions were based on our historical data.6.
Employee Benefit Plans The Company maintains the Chipotle Mexican Grill 401(k) plan (the “401(k) Plan”).
The Company matches 100% of the first 3% of pay contributed by each eligible employee and 50% on the next 2% of pay contributed.
Employees become eligible to receive matching contributions after one year of service with the Company.
For the years ended December 31, 2012, 2011 and 2010, Company matching contributions totaled approximately $2,431, $2,039 and $1,734, respectively.
In February 2012, the Company began offering an employee stock purchase plan (“ESPP”).
Under the ESPP, 250 shares of common stock have been authorized and reserved for issuances to eligible employees.
Employees become eligible to contribute after one year of service with the Company and may contribute up to 15% of their base earnings, subject to an annual maximum dollar amount, toward the monthly purchase of the Company’s common stock.
During 2012, there were 1 shares issued under the ESPP.
The Company also maintains the Chipotle Mexican Grill, Inc.
Supplemental Deferred Investment Plan (the “Deferred Plan”) which covers eligible employees of the Company.
The Deferred Plan is a non-qualified plan that allows participants to make tax-deferred contributions that cannot be made under the 401(k) Plan because of Internal Revenue Service limitations.
Participants’ earnings on contributions made to the Deferred Plan fluctuate with the actual earnings and losses of a variety of available investment choices selected by the participant.
Total liabilities under the Deferred Plan as of December 31, 2012 and 2011 were $10,037 and $6,802, respectively, and are included in other long-term liabilities in the consolidated balance sheet.
The Company matches 100% of the first 3% of pay contributed by each eligible employee and 50% on the next 2% of pay contributed once the 401(k) contribution limits are reached.
For the years ended December 31, 2012, 2011 and 2010, the Company made deferred compensation matches of $213, $179 and $156 respectively, to the Deferred Plan.
Prior to the first quarter of 2012, the Deferred Plan was unfunded, with all earnings and losses recorded in general and administrative expenses in the consolidated statement of income and comprehensive income.
The total expense recognized related to the unfunded portion of the Deferred Plan including the matching contributions was $487, $20 and $610 for the years ended December 31, 2012, 2011 and 2010, respectively.
During the first quarter of 2012, the Company elected to fund its deferred compensation obligations through a rabbi trust.
The rabbi trust is subject to creditor claims in the event of insolvency, but the assets held in the rabbi trust are not available for general corporate purposes.
Amounts in the rabbi trust are invested in mutual funds, as selected by participants, which are designated as trading securities and carried at fair value, and are included in other assets in the consolidated balance sheet.
Fair value of mutual funds is measured using Level 1 inputs (quoted prices for identical assets in active markets), and the fair value of the investments in the rabbi trust was $10,037 as of December 31, 2012.
The Company records trading gains and losses in general and administrative expenses in the consolidated statement of income and comprehensive income, along with the offsetting amount related to the increase or decrease in deferred compensation to reflect its exposure of the Deferred Plan liability.
The Company recorded $240 of unrealized gains on investments held in the rabbi trust during twelve months ended December 31, 2012.
