Use of Non-GAAP Metrics In addition to our results under U.S. GAAP, we use certain non- GAAP measures to assess the performance and prospects of our businesses. In particular, we use EBITDA excluding non-cash items, Free Cash Flow and certain proportionately combined financial metrics. Proportionately combined financial metrics reflect our proportionate interest in our wind and solar facilities. We define EBITDA excluding non-cash items as net income (loss) or earnings the most comparable GAAP measure before interest, taxes, depreciation and amortization and non-cash items including impairments, unrealized derivative gains and losses, adjustments for other non-cash items and pension expense reflected in the statements of operations. EBITDA excluding noncash items also excludes base management fees and performance fees, if any, whether paid in cash or stock. We define Free Cash Flow as cash from operating activities the most comparable GAAP measure which includes cash paid for interest, taxes and pension contributions, less maintenance capital expenditures, which includes principal repayments on capital lease obligations used to fund maintenance capital expenditures, and excludes changes in working capital. Please review our Form 10-Q and press release, filed on November 1, 2017, for a complete discussion of our use of non-gaap metrics. PAGE 2

Proportionately Combined Free Cash Flow Footnotes (1) Represents MIC's proportionately combined interests in the businesses comprising these reportable segments. (2) The sum of the amounts attributable to MIC in proportion to its ownership. (3) Interest expense, net, includes adjustments to derivative instruments, non-cash amortization of deferred financing charges and non-cash amortization of debt discount related to the 2.00% Convertible Senior Notes due October 2023. For the nine months ended September 30, 2016, interest expense, net, also included a non-cash write-off of deferred financing fees related to the February 2016 refinancing at Hawaii Gas. (4) Pension expense primarily consists of interest cost, expected return on plan assets and amortization of actuarial and performance gains and losses. (5) Other non-cash expense (income), net, primarily includes non-cash amortization of tolling liabilities, unrealized gains (losses) on commodity hedges and non-cash gains (losses) related to disposal of assets. See Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) excluding non-cash items, Free Cash Flow and Proportionately Combined Metrics" above for further discussion. (6) Represents the cash interest expense reclassified from MIC Corporate to Atlantic Aviation related to the 2.00% Convertible Senior Notes due October 2023, proceeds of which were used to pay down a portion of Atlantic Aviation's credit facility in October 2016. (7) For the quarter and nine months ended September 30, 2016, EBITDA excluding non-cash items included $13.0 million and $15.5 million, respectively, of insurance recoveries related to damaged docks at IMTT. (8) For the quarter and nine months ended September 30, 2016, maintenance capital expenditures included $13.9 million associated with the rebuilding of damaged docks, the majority of which were insured losses, at IMTT. (9) On March 31, 2016, IMTT acquired the remaining 33.3% interest in its Quebec terminal that it did not previously own. IMTT was previously providing management services to this terminal and no operational changes are expected. Prior to the acquisition, IMTT consolidated the results of the Quebec terminal in its financial statements and adjusted for the portion that it did not own through noncontrolling interests. Since the IMTT Acquisition in July 2014 and prior to the acquisition of the noncontrolling interest, MIC reported IMTT s EBITDA excluding non-cash items and Free Cash Flow including the 33.3% portion of the Quebec terminal. The contribution from the minority interest was not significant. Therefore, there were no changes to our historical EBITDA excluding non-cash items, Free Cash Flow or results generally as a function of acquiring this noncontrolling interest. PAGE 21
