In connection with this offering, the underwriters may engage in stabilizing transactions, which involves
making bids for, purchasing and selling Preferred Units in the open market for the purpose of preventing or retarding a decline in the market price of the Preferred Units while this offering is in progress. These stabilizing transactions may include
making short sales of the Preferred Units, which involves the sale by the underwriters of a greater number of Preferred Units than they are required to purchase in this offering, and purchasing Preferred Units on the open market to cover positions
created by short sales.
The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities
that stabilize, maintain or otherwise affect the price of the Series A Preferred Units or Series B Preferred Units, as applicable, including the imposition of penalty bids. This means that if the underwriters purchase any Preferred Units in the open
market in stabilizing transactions or to cover short sales, the other underwriters can require that the underwriters that sold those Series A Preferred Units or Series B Preferred Units, as applicable, as part of this offering to repay the
underwriting discount received by them.
These activities may have the effect of raising or maintaining the market price of the Preferred Units or
preventing or retarding a decline in the market price of the Preferred Units, and, as a result, the price of the Preferred Units may be higher than the price that otherwise might exist in the open market. If the underwriters commence these
activities, they may discontinue them at any time without notice.
Each of the Series A Preferred Units and the Series B Preferred Units are a new class
of our securities and do not have an established trading market. In addition, since none of the Preferred Units have a stated maturity date, investors seeking liquidity will be limited to selling their units the secondary market absent redemption by
us. Although we have registered the offer and sale of the Preferred Units under the Securities Act, we do not intend to apply for the listing of either the Series A Preferred Units or the Series B Preferred Units on any securities exchange or for
the quotation of the Series A Preferred Units or the Series B Preferred Units on any automated dealer quotation system. In addition, although the underwriters have informed us that they intend to make a market in the Series A Preferred Units or the
Series B Preferred Units, as applicable and as permitted by applicable laws and regulations, they are not obligated to, and they may discontinue their market-making activities at any time without notice. An active market for the Series A Preferred
Units or the Series B Preferred Units may not develop or, if developed, may not continue. In the absence of active trading markets, you may not be able to transfer your Series A Preferred Units or your Series B Preferred Units within the time or at
the prices you desire.
We expect that delivery of the Preferred Units will be made to investors on or about November 16, 2017, which will be the third
business day following the date of this prospectus supplement (such settlement being referred to as T+3). Under Rule
15c6-1
under Exchange Act, trades in the secondary market are required to settle
in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Preferred Units on any date prior to two business days before delivery will be required, by virtue of the fact that the
Preferred Units initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Preferred Units who wish to trade the Preferred Units on any date prior to two
business days before delivery should consult their advisors.
