ABIOMED, INC.  AND SUBSIDIARIES Notes to Consolidated Financial Statements—(Continued) Note 8.
Stock Award Plans and Stock-Based Compensation (Continued) Restricted Stock and Restricted Stock Units The following table summarizes restricted stock and restricted stock unit activity for the fiscal year ended March 31, 2012:
## Table 0 ##
The remaining unrecognized compensation expense for outstanding restricted stock and restricted stock units, including performance-based awards, as of March 31, 2012 was $7.1 million and the weighted-average period over which this cost will be recognized is 2.2 years.
The weighted average grant-date fair value for restricted stock and restricted stock units granted during the years ended March 31, 2012, 2011, and 2010 was $18.13, $10.00 and $7.67 per share, respectively.
The total fair value of restricted stock and restricted stock units vested in fiscal years 2012, 2011, and 2010 was $1.5 million, $1.0 million and $0.4 million, respectively.
Performance-Based Awards Included in the restricted stock and restricted stock units activity discussed above are certain awards granted in fiscal years 2012, 2011 and 2010 that vest subject to certain performance-based criteria.
In June 2010, 311,000 shares of restricted stock and a performance-based award for the potential issuance of 45,000 shares of common stock were issued to certain executive officers and members of senior management of the Company, all of which would vest upon achievement of prescribed service milestones by the award recipients and performance milestones by the Company.
During the year ended March 31, 2011, the Company determined that it met the prescribed performance targets and a portion of these shares and stock options vested.
The remaining shares will vest upon satisfaction of prescribed service conditions by the award recipients.
During the three months ended June 30, 2011, the Company determined that it should have been using the graded vesting method instead of the straight-line method to expense stock-based compensation for the performance-based awards issued in June 2010.
This resulted in additional stock based compensation expense of approximately $0.6 million being recorded during the three months ended June 30, 2011 that should have been recorded during the year ended March 31, 2011.
The Company believes that the amount is not material to its March 31, 2011 consolidated financial statements and therefore recorded the adjustment in the quarter ended June 30, 2011.
During the three months ended June 30, 2011, performance-based awards of restricted stock units for the potential issuance of 284,000 shares of common stock were issued to certain executive officers and members of the senior management, all of which would vest upon achievement of prescribed service milestones by the award recipients and revenue performance milestones by the Company.
As of March 31, 2012, the Company determined that it met the prescribed targets for 184,000 shares underlying these awards and it believes it is probable that the prescribed performance targets will be met for the remaining 100,000 shares, and the compensation expense is being recognized accordingly.
During the year ended March 31, 2012, the Company has recorded $3.3 million in stock-based compensation expense for equity awards in which the prescribed performance milestones have been achieved or are probable of being achieved.
The remaining unrecognized compensation expense related to these equity awards at March 31, 2012 is $3.6 million based on the Company’s current assessment of probability of achieving the performance milestones.
The weighted-average period over which this cost will be recognized is 2.1 years.
when necessary, and provide current and complete financial information including global cash flows, contingent liabilities and sources of liquidity.
A probability weighting is assigned to the listing of loans due to the inherent level of uncertainty related to potential actions that a borrower or guarantor may take to prevent the loan from reaching problem status.
Regions assigns the probability weighting based on an assessment of the likelihood that the necessary actions required to prevent problem loan status will occur.
Additionally, for other loans (for example, smaller dollar loans), a factor based on trends and experience is applied to determine the estimate of potential future downgrades.
Because of the inherent uncertainty in forecasting future events, the estimate of potential problem loans ultimately represents the estimated aggregate dollar amounts of loans as opposed to an individual listing of loans.
The majority of the loans on which the potential problem loan estimate is based are classified as substandard accrual.
Detailed disclosures for substandard accrual loans (as well as other credit quality metrics) are included in Note 6 “Allowance for Credit Losses” to the consolidated financial statements.
The following table provides an analysis of non-accrual loans (excluding loans held for sale) by portfolio segment for the year ended December 31, 2011: Table 21—Analysis of Non-Accrual Loans
## Table 1 ##
(1) All net activity within the consumer portfolio segment other than sales and transfers to held for sale is included as a single net number within the additions line, due to the relative immateriality of consumer non-accrual loans.
(2) Includes charge-offs on loans on non-accrual status and charge-offs taken upon sale and transfer of non-accrual loans to held for sale.
(3) Transfers to held for sale are shown net of charge-offs of $513 million recorded upon transfer.
For additional discussion, see Note 6 “Allowance for Credit Losses” to the consolidated financial statements.
Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization, as applicable.
Premises and equipment at December 31, 2011 decreased $194 million to $2.4 billion compared to year-end 2010.
This decrease primarily resulted from depreciation expense.
Goodwill Goodwill totaled $4.8 billion at December 31, 2011 compared to $5.6 billion in 2010.
Refer to the “Critical Accounting Policies” section earlier in this report for detailed discussions of the Company’s methodology for testing goodwill for impairment and the $745 million impairment charge taken during 2011.
Refer to Note 1 “Summary of Significant Accounting Policies” and Note 9 “Intangible Assets” to the consolidated financial statements, for the methodologies and assumptions used in Step One of the goodwill impairment test.
Additionally, Note 1 “Summary of Significant Accounting Policies” to the consolidated financial statements includes information related to the fair value measurements of certain assets and liabilities and the valuation methodology of such pricing, which is also used for testing goodwill for impairment.
Mortgage Servicing Rights Mortgage servicing rights at December 31, 2011 totaled $182 million compared to $267 million at December 31, 2010.
A summary of mortgage servicing rights is presented in Note 7 “Servicing of Financial Assets” to the consolidated financial statements.
The balances shown represent the right to service mortgage loans that are owned by other investors.
Mortgage servicing rights are presented at fair value as of December 31, 2011 and 2010.
On January 1, 2009, Regions began accounting for mortgage servicing rights at fair market value with any changes to fair value being recorded within mortgage income.
Also, in early 2009, Regions entered into derivative and trading asset transactions to mitigate the impact of market value fluctuations related to mortgage servicing rights.
However, derivative instruments entered into in the future could be materially different from the current risk profile of Regions’ current portfolio.
See the “Mortgage Income” section earlier in this report for detail regarding the effect of mortgage servicing rights and related hedging items on Regions’ consolidated statement of operations.
Other Identifiable Intangible Assets Other identifiable intangible assets totaled $449 million at December 31, 2011 compared to $385 million at December 31, 2010.
The year-over-year increase was due to the acquisition of Regions’ credit card portfolio that resulted in recognition of approximately $175 million of purchased credit card intangibles.
This increase was partially offset by amortization of core deposit intangibles.
Regions noted no indicators of impairment for any other identifiable intangible assets during 2011 or 2010.
See Note 9 “Intangible Assets” to the consolidated financial statements for further information.
Foreclosed Properties Other real estate and certain other assets acquired in foreclosure are reported at the lower of the investment in the loan or fair value of the property less estimated costs to sell.
The following table summarizes foreclosed property activity for the years ended December 31: Table 22—Foreclosed Properties
## Table 2 ##
Note: Approximately 73 percent and 72 percent of the ending balances as of December 31, 2011 and 2010, respectively, relates to properties transferred in to foreclosed properties during the corresponding calendar year.
The approximate future minimum rental commitments as of December 31, 2011, for all non-cancelable leases with initial or remaining terms of one year or more are shown in the following table.
Included in these amounts are all renewal options reasonably assured of being exercised.
