NOTE 10.
STOCK-BASED COMPENSATION Incentive Compensation Plan The UPS Incentive Compensation Plan permits the grant of nonqualified and incentive stock options, stock appreciation rights, restricted stock and stock units, and restricted performance shares and units, to eligible employees.
The number of shares reserved for issuance under the Incentive Compensation Plan is 27 million.
Each share issued pursuant to an option and each share issued subject to the exercised portion of a stock appreciation right will reduce the share reserve by one share.
Each share issued pursuant to restricted stock and stock units, and restricted performance shares and units, will reduce the share reserve by one share.
As of December 31, 2012, stock options, restricted performance units and restricted stock units had been granted under the Incentive Compensation Plan.
We had 27 million shares available to be issued under the Incentive Compensation Plan as of December 31, 2012.
Management Incentive Award Non-executive management earning the right to receive Management Incentive Awards are determined annually by the Salary Committee, which is comprised of executive officers of the Company.
Awards granted to executive officers are determined annually by the Compensation Committee of the UPS Board of Directors.
Our Management Incentive Awards program provides, with certain exceptions, that one-half to two-thirds of the annual Management Incentive Award will be made in Restricted Units (depending upon the level of management involved), which generally vest over a five-year period.
The other one-third to one-half of the award is in the form of cash or unrestricted shares of class A common stock, and is fully vested at the time of grant.
Upon vesting, Restricted Units result in the issuance of the equivalent number of UPS class A common shares after required tax withholdings.
Except in the case of death, disability, or retirement, Restricted Units granted for our Management Incentive Awards and previous Long-Term Incentive Program generally vest over a five year period with approximately 20% of the award vesting at each anniversary date of the grant.
The entire grant is expensed on a straight-line basis over the requisite service period.
All Restricted Units granted are subject to earlier cancellation or vesting under certain conditions.
Dividends earned on Restricted Units are reinvested in additional Restricted Units at each dividend payable date.
Long-Term Incentive Performance Award We also award Restricted Units in conjunction with our Long-Term Incentive Performance Awards program to certain eligible employees.
The Restricted Units ultimately granted under the Long-Term Incentive Performance Awards program will be based upon the achievement of certain performance measures, including growth in consolidated revenue and operating return on invested capital, each year during the performance award cycle, and other measures, including growth in consolidated earnings per share, over the entire three year performance award cycle.
The Restricted Units granted under this program vest at the end of the three year performance award cycle.
UNITED PARCEL SERVICE, INC.  AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 39 Liquidity and Capital Resources Operating Activities The following is a summary of the significant sources (uses) of cash from operating activities (amounts in millions):
## Table 1 ##
(a) Represents depreciation and amortization, gains and losses on derivative and foreign exchange transactions, deferred income taxes, provisions for uncollectible accounts, pension and postretirement benefit expense, stock compensation expense, impairment charges and other non-cash items.
Cash from operating activities remained strong throughout the 2010 to 2012 time period.
Operating cash flow was favorably impacted in 2012, compared with 2011, by lower contributions into our defined benefit pension and postretirement benefit plans; however, this was partially offset by changes in our working capital position, which was impacted by overall growth in the business.
The change in the cash flows for income tax receivables and payables in 2011 and 2010 was primarily related to the timing of discretionary pension contributions during 2010, as discussed further in the following paragraph.
Except for discretionary or accelerated fundings of our plans, contributions to our company-sponsored pension plans have largely varied based on whether any minimum funding requirements are present for individual pension plans.  ?
In 2012, we made a $355 million required contribution to the UPS IBT Pension Plan.  ?
In 2011, we made a $1.2 billion contribution to the UPS IBT Pension Plan, which satisfied our 2011 contribution requirements and also approximately $440 million in contributions that would not have been required until after 2011.  ?
In 2010, we made $2.0 billion in discretionary contributions to our UPS Retirement and UPS Pension Plans, and $980 million in required contributions to our UPS IBT Pension Plan.  ?
The remaining contributions in the 2010 through 2012 period were largely due to contributions to our international pension plans and U. S.  postretirement medical benefit plans.
As discussed further in the “Contractual Commitments” section, we have minimum funding requirements in the next several years, primarily related to the UPS IBT Pension, UPS Retirement and UPS Pension plans.
As of December 31, 2012, the total of our worldwide holdings of cash and cash equivalents was $7.327 billion.
Approximately $4.211 billion of this amount was held in European subsidiaries with the intended purpose of completing the acquisition of TNT Express N. V.  (see note 16 to the consolidated financial statements).
Excluding this portion of cash held outside the U. S.  for acquisition-related purposes, approximately 50%-60% of the remaining cash and cash equivalents are held by foreign subsidiaries throughout the year.
The amount of cash held by our U. S.  and foreign subsidiaries fluctuates throughout the year due to a variety of factors, including the timing of cash receipts and disbursements in the normal course of business.
Cash provided by operating activities in the United States continues to be our primary source of funds to finance domestic operating needs, capital expenditures, share repurchases and dividend payments to shareowners.
To the extent that such amounts represent previously untaxed earnings, the cash held by foreign subsidiaries would be subject to tax if such amounts were repatriated in the form of dividends; however, not all international cash balances would have to be repatriated in the form of a dividend if returned to the U. S.  When amounts earned by foreign subsidiaries are expected to be indefinitely reinvested, no accrual for taxes is provided.
UNITED PARCEL SERVICE, INC.  AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS
## Table 2 ##
In the third quarter of 2012, we reached an agreement with the New England Teamsters and Trucking Industry Pension Fund ("New England Pension Fund"), a multiemployer pension plan in which UPS is a participant, to restructure the pension liabilities for approximately 10,200 UPS employees represented by the Teamsters.
The agreement reflects a decision by the New England Pension Fund's trustees to restructure the fund through plan amendments to utilize a "two pool approach", which effectively subdivides the plan assets and liabilities between two groups of beneficiaries.
As part of this agreement, UPS agreed to withdraw from the original pool of the New England Pension Fund of which it had historically been a participant, and reenter the New England Pension Fund's newly-established pool as a new employer.
Upon ratification of the agreement by the Teamsters in September 2012, we withdrew from the original pool of the New England Pension Fund and incurred an undiscounted withdrawal liability of $2.162 billion to be paid in equal monthly installments over 50 years.
The undiscounted withdrawal liability was calculated by independent actuaries employed by the New England Pension Fund, in accordance with the governing plan documents and the applicable requirements of the Employee Retirement Income Security Act of 1974.
During 2012, we recorded a charge to expense to establish an $896 million withdrawal liability on our consolidated balance sheet, which represents the present value of the $2.162 billion future payment obligation discounted at a 4.25% interest rate.
This discount rate represents the estimated credit-adjusted market rate of interest at which we could obtain financing of a similar maturity and seniority.
As this agreement is not a contribution to the plan, the amounts reflected in the previous table do not include this $896 million non-cash transaction.
