What is policies?
Policies have a vital role in the development of human life. There are various types of policies, such as social, political, and economic policies. They contribute to the development of historical perspective by benefiting the country.
In the United States, each of the 50 states has a unique set of laws, and some of these laws contradict with federal regulations. This is feasible because the federal law frequently has the upper hand when a state's government and the federal government have conflicting laws.
The central government and the smaller political entities both have the authority to enact laws and enjoy some degree of independence from one another.
As a result, there are many chances to create conflict.

Re: Umbra Applied Technologies Group, Inc. 
2018 Chairman’s Letter
(UATG:PK) Year 2018
Chairman's Letter
“UAT Group and its subsidiaries, operate with the understanding that what we do matters and as such our decisions bear consequences.”
Dear Fellow Shareholders,
First, I would like to wish everyone a prosperous New Year and I hope everyone enjoyed the holidays.
As the Chief Executive of a publicly traded company I am the fiduciary for all shareholders, many of whom have invested in UAT Group based on long-term goals such as retirement or to pay for a childs higher education. As such, I advocate and otherwise direct corporate governance practices that are in keeping with long-term value creation for our shareholders and clients. Last year I asked my executive team to help me outline a new strategic frame-work for long-term value creation that could be completed within the year. I am pleased to report that we have been successful in our execution and were so against significant odds.
Over the course of the past 12 months, many of the assumptions on which our plans were based, including low interest rates on capital and an expectation for continued globalization, have failed to sustain despite indicators to the contrary. With U.S. reflation, increasing rates, renewed growth, the increasing turbulence in Asia as a catalyst to geopolitical tensions, the prospective withdrawal of the United Kingdom from the European Union reshaping Europe and the United States undergoing a fundamental reformation of long held fiscal strategies; the economic environment has been and remains quite volatile. This does not mean that this company or the market at large is expected to be impacted negatively but it is a factor when crafting a long-term execution strategy.
