Commercial Banks Banks are challenged to maintain and grow loans with new and aggressive competition, restrictive loan policies, and declining loan yields. Some banks continue to aspire to be investment banks. Investment Banks Investment Banks are expecting a more moderate M&A market and less receptive public markets in the energy sector. Some investment banks aspire to be commercial banks. Private Equity A record levels of private equity capital is competing for limited management teams in a moderating M&A market with high commodity pricing and rising F&D costs. Current investors may be challenged to realize the same level of returns as the predecessor funds.

Mezzanine Firms New entrants and retooled teams have increased to more than a dozen firms, up from 3 or 4 survivors in 2001-02. Pressure to build portfolios has resulted in some of the same mistakes being made all over again. Institutional Loan Investors A record volume of Term B and Second Lien loan product was bought by hedge funds, mutual funds, and CLOs in 2006 and first half of 2007. For deals in the $100 million range that accessed this market, loan pricing was bid down and covenant-lite structures were over-subscribed overnight. Today, some firms that were heavily engaged in leveraged lending with a mark-to-market balance sheet are liquidating energy loans to meet investor demands for redemptions. Clients Energy clients have never enjoyed such an abundance of capital. The challenge is to stay focused on your strategy and not pursue an idea just because you can raise the capital.

The Leveraged Finance capital markets experienced a major correction in the second half of 2007 through the first quarter of 2008. Record forward calendar of committed transactions built through the first half of the year with aggressive structures and pricing weighed upon new issue underwritings Problems started in the Leveraged Loan market following the collapse of structured vehicles that were a major driver of liquidity Formation of new CLOs effectively stalled following sub-prime and asset-backed crisis and inability to syndicate AAA tranches and source equity Energy credit availability since 2Q 2007, while more constrained in the second half of 2007 in sympathy with the broader market, remains one of only a few select industry sectors successfully accessing the leveraged markets across the credit spectrum Since mid-December 2007, energy issuance has comprised the majority of the high yield calendar/high yield primary issuance
