6.What is meant by the “distribution” of CPG Shares?
 On July 1, 2015, NiSource “spun off” its ownership interest in CPG to NiSource shareholders via a special dividend in the form of shares of CPG common stock. NiSource no longer retains an ownership interest in CPG and CPG is now a separate, publicly traded company.

7.What did NiSource stockholders receive in the distribution?
 Holders of NiSource common stock received one (1) share of CPG common stock for each (1) share of NiSource common stock held on the record date. The number of CPG shares distributed to NiSource shareholders was approximately 318 million CPG shares.

8.When did the distribution happen, and what was the “record date”?
 The distribution of CPG common stock shares happened after the close of trading on July 1, 2015. The distribution was to NiSource’s shareholders of record as of 5:00 p.m. Central Time on June 19, 2015 – the record date for the distribution.

9.How were shares of CPG Common Stock distributed?
 Holders of NiSource common stock on the record date received shares of CPG common stock in book-entry form. NiSource shareholders who held their shares of NiSource common stock through a broker, bank, or other nominee had their brokerage account credited with shares of CPG common stock.

10.Did the number of NiSource shares I own change?
 The number of NiSource common stock shares you own did not change as a result of the distribution. Since this was a 1-for-1 distribution, you received the same number of shares in CPG as you own in NiSource as of the record date.

11.What are the U.S. federal income tax consequences of the distribution?
 The transaction is expected to be tax-free to NiSource and its shareholders. You should consult your tax advisor as to the particular consequences of the distribution to you.

12.How do I determine the tax basis of my shares in CPG and NiSource after the separation?
 The aggregate tax basis in your shares of NiSource common stock before the separation will be allocated between the NiSource and CPG common stock held after the separation in proportion to their relative fair market values immediately following the separation. One method for determining relative fair market value would be to use the fair market value for NI and CPGX stock at the close of business on July 2, 2015, the first day of regular trading of CPGX stock. Additional information to assist investors with this process will is available here. Investors are encouraged to consult with their financial and tax advisors for additional information on calculating tax basis for individual investments.
