cash and a commitment to fund the capital needs of the business until such time as its cumulative funding is equal to funding that we have provided from inception through the effective date of the transaction.
The transaction created a new joint venture which does business as Comercia Global Payments Brazil.
As a result of the transaction, we deconsolidated Global Payments Brazil, and we apply the equity method of accounting to our retained interest in Comercia Global Payments Brazil.
We recorded a gain on the transaction of $2.1 million which is included in interest and other income in the consolidated statement of income for the fiscal year ended May 31, 2014.
The results of the Brazil operation from inception until the restructuring into a joint venture on September 30, 2013 were not material to our consolidated results of operations, and the assets and liabilities that we derecognized were not material to our consolidated balance sheet.
American Express Portfolio On October 24, 2013, we acquired a merchant portfolio in the Czech Republic from American Express Limited for $1.9 million.
The acquired assets have been classified as customer-related intangible assets and contract-based intangible assets with estimated amortization periods of 10 years.
PayPros On March 4, 2014, we completed the acquisition of 100% of the outstanding stock of Payment Processing, Inc.  (“PayPros”) for $420.0 million in cash plus $7.7 million in cash for working capital, subject to adjustment based on a final determination of working capital.
We funded the acquisition with a combination of cash on hand and proceeds from our new Term Loan.
PayPros, based in California, is a provider of fully-integrated payment solutions for small-to-medium sized merchants in the United States.
PayPros delivers its products and services through a network of technology-based enterprise software partners to vertical markets that are complementary to the markets served by Accelerated Payment Technologies (“APT”), which we acquired in October 2012.
We acquired PayPros to expand our direct distribution capabilities in the United States and to further enhance our existing integrated solutions offerings.
This acquisition was recorded as a business combination, and the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values.
Due to the timing of this transaction, the allocation of the purchase price is preliminary pending final valuation of intangible assets and deferred income taxes as well as resolution of the working capital settlement discussed above.
The purchase price of PayPros was determined by analyzing the historical and prospective financial statements.
Acquisition costs associated with this purchase were not material.
The following table summarizes the preliminary purchase price allocation (in thousands):
## Table 0 ##
The preliminary purchase price allocation resulted in goodwill, included in the North America merchant services segment, of $271.6 million.
Such goodwill is attributable primarily to synergies with the services offered and markets served by PayPros.
The goodwill associated with the acquisition is not deductible for tax purposes.
The customer-related intangible assets and the contract-based intangible assets have an estimated amortization period of 13 years.
The acquired technology has an estimated amortization period of 7 years.
expense was $272, $292 and $270 in 2019, 2018 and 2017, respectively.
The primary U. S.  defined contribution plan (the U. S.  DC plan) comprises the majority of the expense for the Company's defined contribution plans.
For the U. S.  DC plan, the contribution rate is set annually.
Total contributions for this plan approximated 14% of total participants' annual wages and salaries in 2019, 2018 and 2017.
We maintain The Procter & Gamble Profit Sharing Trust (Trust) and Employee Stock Ownership Plan (ESOP) to provide a portion of the funding for the U. S.  DC plan and other retiree benefits (described below).
Operating details of the ESOP are provided at the end of this Note.
The fair value of the ESOPSeries A shares allocated to participants reduces our cash contribution required to fund the U. S.  DC plan.
Defined Benefit Retirement Plans and Other Retiree Benefits We offer defined benefit retirement pension plans to certain employees.
These benefits relate primarily to local plans outside the U. S.  and, to a lesser extent, plans assumed in previous acquisitions covering U. S.  employees.
We also provide certain other retiree benefits, primarily health care and life insurance, for the majority of our U. S.  employees who become eligible for these benefits when they meet minimum age and service requirements.
Generally, the health care plans require cost sharing with retirees and pay a stated percentage of expenses, reduced by deductibles and other coverages.
These benefits are primarily funded by ESOP Series B shares and certain other assets contributed by the Company.
Obligation and Funded Status.
The following provides a reconciliation of benefit obligations, plan assets and funded status of these defined benefit plans:
## Table 1 ##
CHANGE IN PLAN ASSETS
## Table 2 ##
(1) Primarily non-U.
S. -based defined benefit retirement plans.
(2) Primarily U. S. -based other postretirement benefit plans.
(3) For the pension benefit plans, the benefit obligation is the projected benefit obligation.
For other retiree benefit plans, the benefit obligation is the accumulated postretirement benefit obligation.
(4) Represents the net impact of ESOP debt service requirements, which is netted against plan assets for other retiree benefits.
The underfunding of pension benefits is primarily a function of the different funding incentives that exist outside of the U. S.  In certain countries, there are no legal requirements or financial incentives provided to companies to pre-fund pension obligations prior to their due date.
In these instances, benefit payments are typically paid directly from the Company's cash as they become due.
Amounts in millions of dollars except per share amounts or as otherwise specified.
