The following table presents our consolidated revenues by major solutions and services and by segment, as a percentage of total revenues:
## Table 0 ##
Health Care and Health Care IT Industry Health care expenditures continue to consume an increasing portion of most economies.
In the U. S. , health care spending increased 4.3 percent to $3.30 trillion in 2016, growing to 17.9 percent of the U. S. 's Gross Domestic Product ("GDP").
The Centers for Medicare and Medicaid Services ("CMS") estimates annual U. S.  health care spending will be $5.55 trillion, or 19.9 percent of GDP, by 2025.
We believe this trajectory is unsustainable and that health care IT can play an important role in facilitating a shift from a high-cost health care system that incents volume to a proactive system that incents health, quality and efficiency.
For this change to occur, we believe traditional fee-for-service ("FFS") reimbursement models must continue to shift to valuebased approaches that are more aligned with quality, outcomes, and efficiency.
A signal of this shift occurred in January of 2015 when the U. S.  Department of Health & Human Services laid out a plan to shift 50 percent of Medicare payments to value-based payment models by the end of 2018, and to tie 90 percent of the remaining traditional FFS payments to quality measures.
The shift away from traditional FFS is also evident in growth of lives covered under Accountable Care Organizations ("ACOs").
ACOs are groups of hospitals and providers that focus on providing coordinated, high quality care to Medicare, Medicaid, or commercially insured populations and then share in savings created by lowering the cost of care.
According to the Leavitt Partners publication, Projected Growth of Accountable Care Organizations, December 2015, lives covered under ACOs grew from approximately 5 million in 2011 to more than 20 million in 2015 and are projected to be more than 100 million by 2020.
Another step towards a value-based model occurred with the passage of The Medicare Access and CHIP Reauthorization Act ("MACRA"), which enacts significant reforms to the payment programs under the Medicare Physician Fee Schedule and consolidated three current value-based programs into one.
While each of the different approaches to aligning reimbursement with value has faced challenges in implementation and will continue to evolve, we believe the trend away from traditional FFS will continue.
We believe this growth in government and private models aligning payment with value, quality and outcomes will drive major changes in the way health care is provided in the next decade, and we expect a much greater focus on patient engagement, wellness and prevention.
As health care providers become accountable for proactively managing the health of the populations they serve, we expect them to need ongoing investment in sophisticated information technology solutions that will enable them to predict when intervention is needed so they can improve outcomes and lower the cost of providing care.
The increasingly complex and more clinical outcomes-based reimbursement environment is also contributing to a heightened demand for revenue cycle solutions and services and a desire for these solutions and services to be closely aligned with clinical solutions.
We believe this trend is positive for Cerner because our Cerner Millennium revenue cycle solutions and services are integrated with our clinical solutions, creating a clinically driven revenue cycle solution that has had significant adoption in recent years.

MST’s operating results included the following (in millions):
## Table 3 ##
2014 compared to 2013 MST’s net sales for 2014 were comparable to 2013.
Net sales decreased by approximately $85 million for undersea systems programs due to decreased volume and deliveries; and about $55 million related to the settlements of contract cost matters on certain programs (including a portion of the terminated presidential helicopter program) in 2013 that were not repeated in 2014.
The decreases were offset by higher net sales of approximately $80 million for integrated warfare systems and sensors programs due to increased volume (primarily Space Fence); and approximately $40 million for training and logistics solutions programs due to increased deliveries (primarily Close Combat Tactical Trainer).
MST’s operating profit for 2014 decreased $62 million, or 7%, compared to 2013.
The decrease was primarily attributable to lower operating profit of approximately $120 million related to the settlements of contract cost matters on certain programs (including a portion of the terminated presidential helicopter program) in 2013 that were not repeated in 2014; and approximately $45 million due to higher reserves recorded on certain training and logistics solutions programs.
The decreases were partially offset by higher operating profit of approximately $45 million for performance matters and reserves recorded in 2013 that were not repeated in 2014; and about $60 million for various programs due to increased risk retirements (including MH-60 and radar surveillance programs).
Adjustments not related to volume, including net profit booking rate adjustments and other matters, were approximately $50 million lower for 2014 compared to 2013.2013 compared to 2012 MST’s net sales for 2013 decreased $426 million, or 6%, compared to 2012.
The decrease was primarily attributable to lower net sales of approximately $275 million for various ship and aviation systems programs due to lower volume (primarily PTDS as final surveillance system deliveries occurred during the second quarter of 2012); about $195 million for various integrated warfare systems and sensors programs (primarily Naval systems) due to lower volume; approximately $65 million for various training and logistics programs due to lower volume; and about $55 million for the Aegis program due to lower volume.
The decreases were partially offset by higher net sales of about $155 million for the LCS program due to increased volume.
MST’s operating profit for 2013 increased $168 million, or 23%, compared to 2012.
The increase was primarily attributable to higher operating profit of approximately $120 million related to the settlement of contract cost matters on certain programs (including a portion of the terminated presidential helicopter program); about $55 million for integrated warfare systems and sensors programs (primarily radar and Halifax class modernization programs) due to increased risk retirements; and approximately $30 million for undersea systems programs due to increased risk retirements.
The increases were partially offset by lower operating profit of about $55 million for training and logistics programs, primarily due to the recording of approximately $30 million of charges mostly related to lower-of-cost-or-market considerations; and about $25 million for ship and aviation systems programs (primarily PTDS) due to lower risk retirements and volume.
Operating profit related to the LCS program was comparable.
Adjustments not related to volume, including net profit booking rate adjustments and other matters, were approximately $170 million higher for 2013 compared to 2012.
Backlog Backlog increased in 2014 compared to 2013 primarily due to higher orders on new program starts (such as Space Fence).
Backlog increased slightly in 2013 compared to 2012 mainly due to higher orders and lower sales on integrated warfare system and sensors programs (primarily Aegis) and lower sales on various service programs, partially offset by lower orders on ship and aviation systems (primarily MH-60).
