The decrease in 2008 revenues of $5,478 million compared with 2007, is primarily due to lower revenues at Commercial Airplanes.
Commercial Airplanes revenues decreased by $5,123 million, primarily as a result of decreases in new airplane deliveries reflecting the effects of the labor strike, partially offset by higher intercompany revenues and higher pre-strike deliveries and model mix.
We delivered 104 fewer airplanes than expected during 2008 due to the strike.
This reduced revenue by approximately $6.4 billion for the twelve months ended December 31, 2008.
BDS revenues were unchanged as revenue growth in GS&S was offset by decreases in BMA and N&SS.
BCC revenues decreased by $112 million primarily due to lower interest income on financing receivables and notes and a decrease in the customer financing portfolio.
Other segment revenues increased by $259 million primarily due to the sale of four C-17 aircraft during 2008, that were held under an operating lease.
Unallocated items and eliminations changed by $497 million, primarily due to the intercompany elimination of P-8A revenues recognized by Commercial Airplanes.
Earnings From Operations The following table summarizes our earnings/(loss) from operations:
## Table 0 ##
Operating earnings in 2009 decreased by $1,854 million compared with 2008.
Commercial Airplanes earnings decreased by $1,769 million primarily due to $2,693 million of costs related to the first three 787 flight test aircraft included in research and development expense as a result of our determination in August 2009 that these aircraft could not be sold.
The earnings decrease is also attributable to reach-forward losses on the 747 program which grew by $1,352 million in 2009 which is an increase of $667 million over 2008.
Lower commercial aviation services and intercompany earnings also contributed to lower 2009 earnings.
These decreases were partially offset by higher commercial airplane deliveries in 2009 compared with 2008.
BDS earnings increased by $67 million compared with 2008 primarily due to higher earnings in the BMA segment partially offset by lower earnings in the N&SS segment.
BCC operating earnings decreased $36 million reflecting lower revenues, higher impairment expense and a provision for losses, partially offset by lower interest expense.
Other segment losses decreased by $155 million primarily due to recognition of pre-tax expense of $82 million in the prior year to increase the allowance for losses on customer financing receivables and lower environmental remediation charges compared with the prior year.
Unallocated items and eliminations in 2009 reduced earnings by $271 million compared with 2008, which is further explained in the table below.
Operating earnings in 2008 decreased by $1,880 million compared with 2007.
Commercial Airplanes earnings decreased by $2,398 million compared with the same period in 2007, primarily due to fewer new airplane deliveries resulting from the strike, increased program infrastructure costs related to the strike and revised schedules on 787 and 747-8, and a charge taken on the 747-8 program.
Commercial Airplanes’ research and development expense decreased by $124 million to $2,838 million compared with the same period in 2007, primarily due to lower spending on 787 partially offset by higher spending on 747-8 and lower supplier development cost sharing payments.
BDS earnings decreased by $208 million compared with 2007 primarily due to lower earnings in the BMA segment resulting from charges taken on the Airborne Early Warning and Control (AEW&C).

Accumulated Other Comprehensive Loss Changes in Accumulated other comprehensive income/(loss) (AOCI) by component for the years ended December 31, 2013, 2012 and 2011 were as follows:
## Table 1 ##
(1) Net of tax.
(2) Primarily relates to amortization of actuarial gains/losses for the years ended December 31, 2013 2012 and 2011 totaling $1,516, $1,304 and $909 (net of tax of ($849), ($752) and ($523)) which is included in the net periodic pension cost of which a portion is allocated to production as inventoried costs.
See Note 14.
Note 17 – Derivative Financial Instruments Cash Flow Hedges Our cash flow hedges include foreign currency forward contracts, foreign currency option contracts, commodity swaps, and commodity purchase contracts.
We use foreign currency forward and option contracts to manage currency risk associated with certain transactions, specifically forecasted sales and purchases made in foreign currencies.
Our foreign currency contracts hedge forecasted transactions principally occurring within five years in the future, with certain contracts hedging transactions through 2023.
We use commodity derivatives, such as swaps and fixed-price purchase commitments to hedge against potentially unfavorable price changes for items used in production.
Our commodity contracts hedge forecasted transactions through 2017.
Fair Value Hedges Interest rate swaps under which we agree to pay variable rates of interest are designated as fair value hedges of fixed-rate debt.
The net change in fair value of the derivatives and the hedged items is reported in Boeing Capital interest expense.
Earnings From Operations The following table summarizes Earnings from operations:

* The FAS/CAS service cost adjustment represents the difference between the FAS pension and postretirement service costs calculated under GAAP and costs allocated to the business segments.
** Core operating earnings is a Non-GAAP measure that excludes the FAS/CAS service cost adjustment.
See page 40.
Earnings from operations in 2018 increased by $1,643 million compared with 2017, primarily due to higher earnings at BCA and BGS, which more than offset the decrease at BDS and the change in Unallocated items, eliminations and other.
BCA earnings from operations increased by $2,427 million in 2018 due to higher revenues and improved operating margins.
The increase in operating margins is primarily due to higher 787 margins, improved cost performance and favorable delivery mix.
BGS earnings from operations increased by $276 million in 2018 primarily due to higher revenues, partially offset by higher period costs.
BDS earnings from operations in 2018 decreased by $599 million compared with 2017 as earnings’ growth from higher revenues was more than offset by charges of $691 million related to winning the T-X Trainer and MQ-25 competitions, as well as $199 million of higher KC-46A Tanker reach-forward losses.
Earnings from operations in 2017 increased by $3,817 million compared with 2016 due to higher earnings at BCA and BDS, partially offset by the change in Unallocated items, eliminations and other.
BCA earnings from operations increased by $3,471 million in 2017 primarily due to lower reach-forward losses, lower research and development costs, and improved margins reflecting favorable cost performance.
In 2016, BCA recorded reach-forward losses of $1,258 million on the 747 program and reclassified $1,235 million of 787 flight test aircraft inventory costs to research and development.
The reclassification of flight test aircraft costs was recorded in the second quarter of 2016 as a result of our determination that two 787 flight test aircraft were no longer commercially saleable.
BDS earnings from operations increased by $515 million in 2017 primarily due to lower charges on the KC-46A Tanker and Commercial Crew programs.
During 2018, 2017 and 2016, we recorded reach-forward losses on the KC-46A Tanker program.
In 2018, we recorded charges of $736 million, of which $500 million was recorded at BCA, $222 million at BDS, and $14 million at BGS.
During 2017, we recorded charges of $445 million: $378 million at BCA, $44 million at BGS, and $23 million at BDS.
During 2016, we recorded charges of $1,127 million: $772 million at BCA and $351 million at BDS.
Core operating earnings for 2018 increased by $1,754 million compared with 2017 primarily due to higher earnings at BCA and BGS, partially offset by lower earnings at BDS and higher unallocated expenses.
