Crunch Time - Leverage, Liquidity, and M&A Issues for Upstream Energy Companies in the Second Half of 2015

When oil prices fell precipitously in the second half of 2014, many predicted that the resulting financial pressures on U.S. E&P companies would force them to rapidly scale back production. To date, the industry has defied these predictions – greater efficiency, high-grading of drilling plans, cost savings, robust capital raising and strong hedging positions have allowed domestic producers to maintain production at or near historically high levels even with rig counts falling significantly.

SEC Approves General Solicitation and Advertising for Accredited Investor-Only Securities Offerings: Excludes

On July 10, 2013, the U.S. Securities and Exchange Commission ("SEC") fulfilled its Congressional mandate by adopting new rules that will dramatically affect the landscape for unregistered securities offerings in the United States. These new rules authorize the use of general advertising and general solicitation methods in accredited investor-only offerings under the newly amended Rule 506. Historically, securities offerings that were not registered with the SEC were uniformly described as "private offerings," because that was their common identifying feature – the securities could not be publicly offered. With the adoption of new Rule 506(c), that common understanding has been eliminated.
