are expected to reverse in the future, which is generally a 22.5% blended federal and state tax rate. However, it is still analyzing certain aspects of the Act and refining its calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The Company has included in its income tax rate a preliminary estimate related to executive compensation, Alternative Minimum Tax refundable credits, taxation in its foreign jurisdictions, and re-measurement of its deferred taxes. Once the accounting for income taxes on these items is complete, it will be reflected and reported in the applicable quarter during 2018. Additionally, because of the complexities of the new legislation, the Company has not elected an accounting policy at this time with respect to the newly enacted global intangible low-taxed income, or GILTI, provisions. An accounting election to either treat GILTI as part of deferred taxes or a period cost will be made once further analysis and interpretation of the tax legislation is complete.
10. Commitments and Contingencies
Vessel Construction
In November 2011, the Company commenced, and later expanded, its fifth OSV newbuild program. This program consisted of vessel construction contracts with three domestic shipyards to build four 300 class OSVs, five 310 class OSVs, ten 320 class OSVs, three 310 class MPSVs and two 400 class MPSVs. As of December 31, 2017, the Company had placed in service 22 vessels under such program. The two remaining vessels under this 24-vessel domestic newbuild program are currently expected to be placed in service during 2019. Based on current contracts and internal estimates, the aggregate total cost of this program, before construction period interest, is expected to be approximately $1,335.0 million. From the inception of this program through December 31, 2017, the Company had incurred construction costs of approximately $1,272.7 million, or 95.3%, of total expected project costs.
Operating Leases
The Company is obligated under certain operating leases for office space and shore-base facilities. The Covington facility lease provides for an initial term expiring in September 2025 with three additional five-year renewal period options. The Company leases two adjacent shore-base facilities in Port Fourchon. At December 31, 2017, the leases had approximately one year remaining on their existing terms and the Company has multiple renewal options on such facilities. Rent expense related to operating leases was approximately $3.9 million, $4.0 million and $4.1 million for the years ending December 31, 2017, 2016 and 2015, respectively.
Future minimum payments under noncancelable leases for years subsequent to 2017 are as follows (in thousands):

The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 33 of the Merchant Marine Act of 1920, or the Jones Act. Third party liabilities and pollution claims that relate to vessel operations are covered by the Company’s entry in a mutual protection and indemnity association, or P&I Club, as well as by marine liability policies in excess of the P&I Club’s coverage. The Company provides reserves for any individual claim deductibles for which the Company remains responsible by using an estimation process that considers Company-specific and industry data, as well as management’s experience, assumptions and consultation with outside counsel.
