GAAP earnings per share increased to $4.15 and core earnings per share (non-GAAP)* increased to $3.64 reflecting strong performance across the company.

The company's cash flow guidance is increased to between $15.0 and $15.5 billion, driven by improved performance. Full year EPS guidance is increased by $0.50to between $16.40 and $16.60, and core earnings per share (non-GAAP)* guidance is increased to between $14.30 and $14.50 on performance.

"Customers continue to recognize the value of our products and services, with strong orders booked in the quarter for defense, services and commercial offerings, including 221 net commercial aircraft orders."

"During the quarter we captured important new business, including an initial contract for 28 F/A-18 Super Hornets for Kuwait, a Ground-based Midcourse Defense program contract extension from the Missile Defense Agency, and we delivered the first Space Launch System intertank hardware to NASA. We achieved the first flight of the 737 MAX 7, and delivered the first 787-10 Dreamliner and the first 737 MAX 9. Within our services business, we received a follow-on contract to support the Royal Canadian Air Force's Chinook fleet, captured a landing gear exchange contract for Aeromexico, and released Self-Service Analytics to complement our digital solutions portfolio. All of these milestones demonstrated the value we bring to our customers through the strength of our One Boeing offerings."

Going forward, we remain focused on our disciplined growth strategy, improved profitability and cash flow to ensure we meet our commitments to our customers and our shareholders."

Segment Results

Commercial Airplanes

Commercial Airplanes first-quarter revenue was $13.7 billion reflecting higher deliveries and mix (Table 4). First-quarter operating margin increased to 11.0 percent, reflecting strong operating performance on production programs.

During the quarter, Commercial Airplanes delivered 184 airplanes, including delivery of the first 787-10 Dreamliner to Singapore Airlines and delivery of the first 737 MAX 9 to Lion Air Group.

Development on the 777X program remains on track as production began on the first 777X fuselage for structural testing.

Additional Financial Information

At quarter-end, Boeing Capital's net portfolio balance was $2.9 billion. Total pension expense for the first quarter was $40 million, down from $97 million in the same period of the prior year. Revenue in other unallocated items and eliminations decreased primarily due to the sale of aircraft previously leased to customers in the first quarter of 2017. The effective tax rate for the first quarter decreased from the same period in the prior year primarily due to the reduction of the federal tax rate to 21%.

Outlook

The Company's 2018 guidance is updated below (Table 8).

1 Approximately $1.4 billion of pension expense is expected to be allocated to the business segments* Non-GAAP measures. Complete definitions of Boeing's non-GAAP measures are on page 7, "Non-GAAP Measures Disclosures."

Non-GAAP Measures Disclosures

We supplement the reporting of our financial information determined under Generally Accepted Accounting Principles in the United States of America (GAAP) with certain non-GAAP financial information. The non-GAAP financial information presented excludes certain significant items that may not be indicative of, or are unrelated to, results from our ongoing business operations. We believe that these non-GAAP measures provide investors with additional insight into the company's ongoing business performance. These non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. We encourage investors to review our financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. The following definitions are provided:

Core Operating Earnings, Core Operating Margin and Core Earnings Per Share

Core operating earnings is defined as GAAP earnings from operations excluding the FAS/CAS service cost adjustment. 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 margin is defined as core operating earnings expressed as a percentage of revenue. Core earnings per share is defined as GAAP diluted earnings per shareexcluding the net earnings per share impact of the FAS/CAS service cost adjustment and Non-operating pension and postretirement expenses. Non-operating pension and postretirement expenses represent the components of net periodic benefit costs other than service cost. Pension costs, comprising service and prior service costs computed in accordance with GAAP are allocated to Commercial Airplanes and BGS businesses supporting commercial customers. Pension costs allocated to BDS and BGS businesses supporting government customers are computed in accordance with U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than GAAP. CAS costs are allocable to government contracts. Other postretirement benefit costs are allocated to all business segments based on CAS, which is generally based on benefits paid. Management uses core operating earnings, core operating margin and core earnings/per share for purposes of evaluating and forecasting underlying business performance. Management believes these core earnings measures provide investors additional insights into operational performance as they exclude non-service pension and post-retirement costs, which primarily represent costs driven by market factors and costs not allocable to government contracts. A reconciliation between the GAAP and non-GAAP measures is provided on page 14.

Free Cash Flow

Free cash flow is defined as GAAP operating cash flow without capital expenditures for property, plant and equipment additions. Management believes free cash flow provides investors with an important perspective on the cash available for shareholders, debt repayment, and acquisitions after making the capital investments required to support ongoing business operations and long term value creation. Free cash flow does not represent the residual cash flow available for discretionary expenditures as it excludes certain mandatory expenditures such as repayment of maturing debt. Management uses free cash flow as a measure to assess both business performance and overall liquidity. Table 2 provides a reconciliation between GAAP operating cash flow and free cash flow.
