securities. As we have both domestic and international plans, these assumptions differ based on varying factors specific to each
particular country or economic environment.
The discount rate utilized in 2013 to determine the projected benefit obligation at the measurement date for our United
Kingdom pension plan, which constituted 81% of our international plans’ pension obligations, was 4.5%, compared to a
discount rate of 4.6% utilized in 2012. The expected long-term rate of return assumption used for our United Kingdom pension
plan expense was 6.5% in 2013, compared to 6.7% in 2012.
The following table illustrates the sensitivity to changes in certain assumptions, holding all other assumptions
constant, for our United Kingdom pension plan.

Our international defined benefit plans reduced pretax income by $32 million in 2013, $26 million in 2012, and $27
million in 2011. Included in these amounts was income from expected pension returns of $44 million in 2013, $45 million in
2012, and $47 million in 2011. Actual returns on international plan assets totaled $117 million in 2013, compared to $87
million in 2012. Our net actuarial loss, net of tax, related to international pension plans was $222 million at December 31, 2013
and $208 million at December 31, 2012. In our international plans where employees earn additional benefits for continued
service, actuarial gains and losses will be recognized in operating income over a period of three to 17 years, which represents
the estimated average remaining service of the participant group expected to receive benefits. In our international plans where
benefits are not accrued for continued service, actuarial gains and losses will be recognized in operating income over a period
of 17 to 33 years, which represents the estimated average remaining lifetime of the benefit obligations. These ranges reflect
varying maturity levels among the plans.
During 2013, we made contributions of $26 million to fund our international defined benefit plans. We expect to make
contributions of approximately $17 million to our international defined benefit plans in 2014.
The actuarial assumptions used in determining our pension benefit obligations may differ materially from actual
results due to changing market and economic conditions, higher or lower withdrawal rates, and longer or shorter life spans of
participants. While we believe that the assumptions used are appropriate, differences in actual experience or changes in
assumptions may materially affect our financial position or results of operations. See Note 14 to the consolidated financial
statements for further information related to defined benefit and other postretirement benefit plans.
Allowance for bad debts
We evaluate our accounts receivable through a continuous process of assessing our portfolio on an individual customer
and overall basis. This process consists of a thorough review of historical collection experience, current aging status of the
customer accounts, financial condition of our customers, and whether the receivables involve retainages. We also consider the
economic environment of our customers, both from a marketplace and geographic perspective, in evaluating the need for an
allowance. Based on our review of these factors, we establish or adjust allowances for specific customers and the accounts
receivable portfolio as a whole. This process involves a high degree of judgment and estimation, and frequently involves
significant dollar amounts. Accordingly, our results of operations can be affected by adjustments to the allowance due to actual
write-offs that differ from estimated amounts. Our estimates of allowances for bad debts have historically been accurate. Over
the last five years, our estimates of allowances for bad debts, as a percentage of notes and accounts receivable before the
allowance, have ranged from 1.6% to 3.0%. At December 31, 2013, allowance for bad debts totaled $117 million, or 1.9% of
notes and accounts receivable before the allowance. At December 31, 2012, allowance for bad debts totaled $92 million, or
1.6% of notes and accounts receivable before the allowance. A hypothetical 100 basis point change in our estimate of the
collectability of our notes and accounts receivable balance as of December 31, 2013 would have resulted in a $62 million
adjustment to 2013 total operating costs and expenses. See Note 3 to the consolidated financial statements for further
information.
