Certain amounts previously reported in the consolidated financial statements have been reclassified in the accompanying consolidated financial statements to conform to the current period’s presentation, primarily to change the presentation of Gain on real estate transactions, earnout from prior acquisitions, and impairment of real estate on the consolidated statement of operations.

New in FY2018

The change was made for the prior periods as the Securities and Exchange Commission has eliminated Rule 3-15(a) of Regulation S-X as part of Release No. 33-10532; 34-83875; IC-33203, which had required REITs to present gain and losses on sale of properties outside of continuing operations in the statement of operations.

Immaterial Correction to Consolidated Balance Sheets

New in FY2018

In connection with the preparation of the financial statements for the quarter ended March 31, 2018, the Company determined that the negative balances in the "Investments in unconsolidated real estate ventures" line should be presented separately as liabilities.

New in FY2018

As a result, $5,816 should have been reported as "Cash distributions in unconsolidated real estate ventures" as of December 31, 2017.

New in FY2018

The Company concluded that the amount was not material to the consolidated balance sheet as of December 31, 2017 but has elected to present these amounts as liabilities in the accompanying financial statements for consistent presentation.

New in FY2018

The classification error had no effect on the previously reported consolidated statements of operations, comprehensive income, stockholders' equity or cash flows for the year ended December 31, 2017.

New in FY2018

For

New in FY2018

The Company's management fees are earned subject to the terms of the related management services agreements ("MSAs").

New in FY2018

These MSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services.

New in FY2018

These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties and unconsolidated joint ventures.

New in FY2018

MSAs generally have original terms from three to five years, after which management services are provided on a month-to-month basis unless terminated.

New in FY2018

Management fees are due on the last day of each calendar month that management services are provided.

New in FY2018

The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month.

New in FY2018

The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control.

New in FY2018

Therefore, the Company recognizes the revenue at the end of each month once the uncertainty is resolved.

New in FY2018

Due to the standardized terms of the MSAs, the Company accounts for all MSAs in a similar, consistent manner.

New in FY2018

Therefore, no disaggregated information relating to MSAs is presented.
