Compensation and Retirement Disclosure [Abstract]

COMPANY-SPONSORED EMPLOYEE BENEFIT PLANS

We sponsor various retirement and pension plans, including defined benefit and defined contribution plans which cover our employees worldwide.

U.S. Pension Benefits

In the U.S. we maintain the following single-employer defined benefit pension plans: The UPS Retirement Plan, the UPS Pension Plan, the UPS IBT Pension Plan and the UPS Excess Coordinating Benefit Plan, a non-qualified plan.

The UPS Retirement Plan is noncontributory and includes substantially all eligible employees of participating domestic subsidiaries who are not members of a collective bargaining unit, as well as certain employees covered by a collective bargaining agreement. This plan generally provides for retirement benefits based on average compensation levels earned by employees prior to retirement. Benefits payable under this plan are subject to maximum compensation limits and the annual benefit limits for a tax-qualified defined benefit plan as prescribed by the Internal Revenue Service (“IRS”).

The UPS Excess Coordinating Benefit Plan is a non-qualified plan that provides benefits to certain participants in the UPS Retirement Plan for amounts that exceed the benefit limits described above.

The UPS Pension Plan is noncontributory and includes certain eligible employees of participating domestic subsidiaries and members of collective bargaining units that elect to participate in the plan. This plan generally provides for retirement benefits based on service credits earned by employees prior to retirement.

The UPS IBT Pension Plan is noncontributory and includes employees that were previously members of the Central States Pension Fund, a multiemployer pension plan, in addition to other eligible employees who are covered under certain collective bargaining agreements. This plan generally provides for retirement benefits based on service credits earned by employees prior to retirement.

International Pension Benefits

We also sponsor various defined benefit plans covering certain of our international employees. The majority of our international obligations are for defined benefit plans in Canada and the United Kingdom. In addition, many of our international employees are covered by government-sponsored retirement and pension plans. We are not directly responsible for providing benefits to participants of government-sponsored plans.

U.S. Postretirement Medical Benefits

We also sponsor postretirement medical plans in the U.S. that provide healthcare benefits to our retirees who meet certain eligibility requirements and who are not otherwise covered by multiemployer plans. Generally, this includes employees with at least 10 years of service who have reached age 55 and employees who are eligible for postretirement medical benefits from a Company-sponsored plan pursuant to collective bargaining agreements. We have the right to modify or terminate certain of these plans. These benefits have been provided to certain retirees on a noncontributory basis; however, in many cases, retirees are required to contribute all or a portion of the total cost of the coverage.

Defined Contribution Plans

We also sponsor several defined contribution plans for all employees not covered under collective bargaining agreements, and for certain employees covered under collective bargaining agreements. The Company matches, in shares of UPS common stock or cash, a portion of the participating employees’ contributions. Matching contributions charged to expense were $104, $95 and $90 million for 2015, 2014 and 2013, respectively.

Contributions are also made to defined contribution money purchase plans under certain collective bargaining agreements. Amounts charged to expense were $83, $82 and $80 million for 2015, 2014 and 2013, respectively.

Actuarial Assumptions

The table below provides the weighted-average actuarial assumptions used to determine the net periodic benefit cost.



	U.S. Pension Benefits						U.S. Postretirement Medical Benefits						International Pension Benefits
	2015		2014		2013		2015		2014		2013		2015		2014		2013

The table below provides the weighted-average actuarial assumptions used to determine the benefit obligations of our plans.



	U.S. Pension Benefits				U.S. Postretirement Medical Benefits				International Pension Benefits
	2015		2014		2015		2014		2015		2014
Discount rate	4.86	%	4.40	%	4.79	%	4.18	%	3.51	%	3.56	%
Rate of compensation increase	4.29	%	4.29	%	N/A		N/A		3.04	%	3.08	%

A discount rate is used to determine the present value of our future benefit obligations. To determine our discount rate for our U.S. pension and postretirement benefit plans, we use a bond matching approach to select specific bonds that would satisfy our projected benefit payments. We believe the bond matching approach reflects the process we would employ to settle our pension and postretirement benefit obligations. For our international plans, the discount rate is determined by matching the expected cash flows of a sample plan of similar duration to a yield curve based on long-term, high quality fixed income debt instruments available as of the measurement date. These assumptions are updated each measurement date, which is typically annually.

As of December 31, 2015, the impact of each basis point change in the discount rate on the projected benefit obligation of the pension and postretirement medical benefit plans are as follows (in millions):



	Increase (Decrease) in the Projected Benefit Obligation
	Pension Benefits			Postretirement Medical Benefits
One basis point increase in discount rate	$	(60	)	$	(2	)
One basis point decrease in discount rate	$	66		$	3

The Society of Actuaries ("SOA") published mortality tables and improvement scales are used in developing the best estimate of mortality for plans in the U.S. On October 27, 2014, the SOA published updated mortality tables and an updated improvement scale, both of which reflect longer anticipated lifetimes. Based on an evaluation of these new tables and our perspective of future longevity, we updated the mortality assumptions for purposes of measuring pension and other postretirement benefit obligations at December 31, 2014. The change to the mortality assumption increased the year-end pension and other postretirement benefit obligations by $1.119 billion and $51 million, respectively. At December 31, 2014, we also revised the retirement assumptions for non-union plan participants based on recent retirement experience. The change to the retirement assumption decreased the year-end pension and other postretirement benefit obligations by $383 and $234 million, respectively.

Assumptions for the expected return on plan assets are used to determine a component of net periodic benefit cost for the fiscal year. The assumption for our U.S. plans was developed using a long-term projection of returns for each asset class, and taking into consideration our target asset allocation. The expected return for each asset class is a function of passive, long-term capital market assumptions and excess returns generated from active management. The capital market assumptions used are provided by independent investment advisors, while excess return assumptions are supported by historical performance, fund mandates and investment expectations.

On September 25, 2015, the Central States Pension Fund ("CSPF") submitted a proposed pension suspension plan to the U.S. Department of Treasury under the Multiemployer Pension Reform Act of 2014 ("MPRA"). The CSPF plan proposes to make retirement benefit reductions to the CSPF participants, including to the benefits of UPS employee participants retiring on or after January 1, 2008. In 2007, UPS fully funded its allocable share of the unfunded vested benefits in the CSPF when it was agreed that UPS could withdraw from the CSPF in consideration of a $6.100 billion withdrawal liability. Under a collective bargaining agreement with the IBT, UPS agreed to provide supplemental benefits under the UPS/IBT Full-Time Employee Pension Plan to offset the effect of certain benefit reductions by the CSPF applicable to UPS participants retiring on or after January 1, 2008, which resulted in the initial recognition of a $1.701 billion pension liability in 2007. UPS has reviewed the CSPF’s proposed plan to evaluate the validity of the actions taken by the CSPF, the plan’s compliance with the MPRA (and proposed regulations thereunder) and its potential impact on UPS’s funding obligations under the UPS/IBT Full-Time Employee Pension Plan.

We are vigorously challenging the proposed suspension plan because it does not fully comply with the law and we do not believe certain actions by the CSPF are valid. Accordingly, we have not assumed or recognized a liability for supplemental benefits within the UPS/IBT Full-Time Employee Pension Plan due to the submission of the CSPF’s proposed plan to the U.S. Department of Treasury. Further we are not able to estimate a range of potential additional obligations, if any, or determine whether any such amounts are material, due to uncertainties regarding the validity of actions taken by the CSPF, incomplete information regarding the CSPF’s proposed benefit reductions, uncertainties regarding the process and standards under the MPRA, whether the proposed plan complies with the MPRA (and proposed regulations thereunder) and the effect of various discount rates and other actuarial assumptions.

For plans outside the U.S., consideration is given to local market expectations of long-term returns. Strategic asset allocations are determined by plan based on the nature of liabilities and considering the demographic composition of the plan participants.

Healthcare cost trends are used to project future postretirement benefits payable from our plans. For year-end 2015 U.S. plan obligations, future postretirement medical benefit costs were forecasted assuming an initial annual increase of 7.0%, decreasing to 4.5% by the year 2021 and with consistent annual increases at those ultimate levels thereafter.

Assumed healthcare cost trends can have a significant effect on the amounts reported for our postretirement medical plans. A one percent change in assumed healthcare cost trend rates would have had the following effects on 2015 results (in millions):



	1% Increase		1% Decrease
Effect on total of service cost and interest cost	$	4	$	(4	)
Effect on postretirement benefit obligation	$	73	$	(79	)

The accumulated benefit obligation for our pension plans as of the measurement dates in 2015 and 2014 was $35.320 and $35.867 billion, respectively.

Benefit payments under the pension plans include $22 and $19 million paid from employer assets in 2015 and 2014, respectively. Benefit payments (net of participant contributions) under the postretirement medical benefit plans include $111 and $122 million paid from employer assets in 2015 and 2014, respectively. Such benefit payments from employer assets are also categorized as employer contributions.

At December 31, 2015 and 2014, the projected benefit obligation, the accumulated benefit obligation and the fair value of plan assets for pension plans with benefit obligations in excess of plan assets were as follows (in millions):



	Projected Benefit Obligation Exceeds the Fair Value of Plan Assets				Accumulated Benefit Obligation Exceeds the Fair Value of Plan Assets
	2015		2014		2015		2014
U.S. Pension Benefits:
Projected benefit obligation	$	36,846	$	37,521	$	36,846	$	37,521
Accumulated benefit obligation	34,210		34,725		34,210		34,725
Fair value of plan assets	28,887		28,828		28,887		28,828
International Pension Benefits:

Accumulated benefit obligation	416		426		401		398
Fair value of plan assets	247		261		232		232

The accumulated postretirement benefit obligation exceeds plan assets for all of our U.S. postretirement medical benefit plans.

Pension and Postretirement Plan Assets

The applicable benefit plan committees establish investment guidelines and strategies, and regularly monitor the performance of the funds and portfolio managers. Our investment guidelines address the following items: governance, general investment beliefs and principles, investment objectives, specific investment goals, process for determining/maintaining the asset allocation policy, long-term asset allocation, rebalancing, investment restrictions/prohibited transactions, portfolio manager structure and diversification (which addresses limits on the amount of investments held by any one manager to minimize risk), portfolio manager selection criteria, plan evaluation, portfolio manager performance review and evaluation, and risk management (including various measures used to evaluate risk tolerance).

We invest pension assets in accordance with applicable laws and regulations. The long-term primary investment objectives for our pension assets are to: (1) provide for a reasonable amount of long-term growth of capital, with prudent exposure to risk; and protect the assets from erosion of purchasing power; (2) provide investment results that meet or exceed the plans’ expected long-term rate of return; and (3) match the duration of the liabilities and assets of the plans to reduce the potential risk of large employer contributions being necessary in the future. The plans strive to meet these objectives by employing portfolio managers to actively manage assets within the guidelines and strategies set forth by the benefit plan committees. These managers are evaluated by comparing their performance to applicable benchmarks.

Fair Value Measurements

Pension assets utilizing Level 1 inputs include equity investments, corporate debt instruments, and U.S. government securities. Fair values were determined by closing prices for those securities traded on national stock exchanges, while securities traded in the over-the-counter market and listed securities for which no sale was reported on the valuation date are valued at the mean between the last reported bid and asked prices.

Level 2 assets include certain bonds that are valued based on yields currently available on comparable securities of other issues with similar credit ratings, mortgage-backed securities that are valued based on cash flow and yield models using acceptable modeling and pricing conventions, and certain investments that are pooled with other investments held by the trustee in a commingled employee benefit trust fund. The investments in the commingled funds are valued by taking the percentage owned by the respective plan in the underlying net asset value of the trust fund, which was determined in accordance with the paragraph above.

Certain investments’ estimated fair value is based on unobservable inputs that are not corroborated by observable market data and are thus classified as Level 3. These investments include commingled funds comprised of corporate and government bonds, hedge funds, real estate investments and private equity funds. The fair values may, due to the inherent uncertainty of valuation for those alternative investments, differ significantly from the values that would have been used had a ready market for the alternative investments existed, and the differences could be material. These investments are described further below:

•

Hedge Funds: We maintain plan assets invested in hedge funds that pursue multiple strategies to diversify risk and reduce volatility. Investments in hedge funds are valued using reported net asset values as of December 31. These assets are primarily invested in a portfolio of diversified, direct investments and funds of hedge funds. Most of these funds allow redemptions either quarterly or semi-annually after a two to three month notice period, while other funds allow for redemption after only a brief notification period with no restriction on redemption frequency. At December 31, 2015, unfunded commitments to these hedge funds totaling approximately $234 million are expected to be contributed over the remaining investment period, typically ranging between two and four years.

•

Risk Parity Funds: We maintain plan assets invested in risk parity strategies in order to provide diversification and balance risk / return objectives. Investments in risk parity funds are valued using reported net asset values as of December 31. These strategies reflect a multi-asset class balanced risk approach generally consisting of equity, interest rates, credit, and commodities. These funds allow for monthly redemptions with only a brief notification period. No unfunded commitments existed with respect to these funds as of December 31, 2015.

•

Real Estate and Private Equity Funds: We maintain plan assets invested in limited partnership interests in various private equity and real estate funds. These private equity and real estate investment funds are valued using fair values per the most recent partnership audited financial reports, adjusted as appropriate for any lag between the date of the financial reports and December 31. The real estate and private equity investments consist of U.S. and non-U.S. investments and are broadly diversified. Limited provision exists for the redemption of these interests by the limited partners that invest in these funds until the end of the term of the partnerships, typically ranging between 10 and 15 years from the date of inception. An active secondary market exists for similar partnership interests, although no particular value (discount or premium) can be guaranteed. At December 31, 2015, unfunded commitments to such limited partnerships totaling approximately $1.855 billion are expected to be contributed over the remaining investment period, typically ranging between three and six years.

Our funding policy for U.S. plans is to contribute amounts annually that are at least equal to the amounts required by applicable laws and regulations, or to directly fund payments to plan participants, as applicable. International plans will be funded in accordance with local regulations. Additional discretionary contributions may be made when deemed appropriate to meet the long-term obligations of the plans. Expected benefit payments for pensions will be primarily paid from plan trusts. Expected benefit payments for postretirement medical benefits will be paid from plan trusts and corporate assets.
