All the amounts for depreciation and for loss from revaluation are included as part of the depreciation, amortization, and loss from revaluation on the consolidated statements of profit or loss.

The accumulated depreciation on property, vessels and equipment at December 31, 2020 and 2019 is $290,056 and $261,862, respectively.

(a)

It is mainly comprised of the surplus for revaluation of land for $ 330,571 and a deficit for revaluation of vessels for $ 16,135.

(b)

Corresponds mainly to the cancellation of the project called “Terminal Quintana Roo”, derived from changes in the conditions of the project previously considered by Management.

(c)

On August 30, 2019, the sale of the vessel SMR Manzanillo to Bricor Servicios Portuarios Mexicanos, S.A. de C.V. by Transportación Marítima Mexicana, S.A. de C.V., a subsidiary of Grupo TMM, was complete for an amount of $15,703, generating a profit of $ 4,410.

(d)

It is comprised mainly of disposal of the TMM Colima vessel in the divestiture of Snekke, S.A. de C.V. of Grupo TMM for $339,038, which is partially offset by the revaluation surplus of $1,827.

(e)

Includes the surplus for revaluation of lands and properties for $310,833 and $66,518, respectively.

(f)

Corresponds to the construction of infrastructure for various projects related to the storage and transportation of hydrocarbons and refined petroleum products.

(g)

During 2018, the offshore vessel ‘Subsea 88’ suffered a major mishap in one of its areas and for which it stopped operating. As of December 31, 2018, Grupo TMM was making the corresponding insurance claims without a final settlement having been issued on the mishap as of that date. Since the repair of the ship requires a substantial time that affects future cash flows, Management recognized a loss in fair value in the amount of $206,076.
