General and administrative expenses in the second quarter of 2020 were $10.5 million, compared to $9.3 million in the second quarter of 2019. The increase was due primarily to a $1.9 million increase in legal expenses, primarily related to a $2.5 million settlement accrual, described below, partially offset by a $0.7 million decrease in labor related costs related to a decrease in management bonus expense and a $0.1 million decrease in other general and administrative expenses.
During the second quarter of 2020, the Company recognized a $2.5 million expense related to an agreement in principle to resolve the longstanding lawsuit involving a contract dispute with one of the Company’s franchisees concerning asserted territory rights.
During the second quarter of 2019, the Company completed the sale of four company-operated restaurants within the San Francisco, CA area to an existing franchisee and seven company-operated restaurants in the Phoenix, AZ area to another existing franchisee. This resulted in a net loss on sale of restaurants of $0.9 million for the quarter, and a total net loss on sale of restaurants of $5.1 million, including the $4.2 million loss on held for sale assets recognized in the first quarter. Additionally, the Company received insurance proceeds of $10.0 million related to the settlement of a previously disclosed securities class action lawsuit.
Net income for the second quarter of 2020 was $5.5 million, or $0.16 per diluted share, compared to net income of $14.1 million, or $0.37 per diluted share, in the second quarter of 2019. Pro forma net income was $6.9 million, or $0.20 per diluted share, during the second quarter of 2020, compared to $8.7 million, or $0.23 per diluted share, during the second quarter of 2019. A reconciliation between GAAP net income and pro forma net income is included in the accompanying financial data. See also “Non-GAAP Financial Measures.”

Key Financial Definitions
Comparable restaurant sales reflect the change in year-over-year sales for the comparable company, franchised and total system restaurant base. The comparable restaurant base is defined to include those restaurants open for 15 months or longer and excludes restaurants that were closed during the applicable period. At June 24, 2020, there were 191 restaurants in our comparable company-operated restaurant base and 469 restaurants in our comparable system restaurant base.
Restaurant contribution and restaurant contribution margin are neither required by, nor presented in accordance with GAAP. Restaurant contribution is defined as company-operated restaurant revenue less company restaurant expenses, which are food and paper costs, labor and related expenses, and occupancy and other operating expenses. Restaurant contribution excludes certain costs, such as general and administrative expenses, depreciation and amortization, asset impairment and closed-store reserves, loss on sale of restaurants, recovery of securities lawsuits related legal expenses and other costs that are considered normal operating costs. Accordingly, restaurant contribution is not indicative of overall Company results and does not accrue directly to the benefit of shareholders because of the exclusion of certain corporate-level expenses. Restaurant contribution margin is defined as restaurant contribution as a percentage of net company-operated restaurant revenue. See also “Non-GAAP Financial Measures.”
EBITDA and adjusted EBITDA are neither required by, nor presented in accordance with, GAAP. EBITDA represents net income before interest expense, provision for income taxes, depreciation, and amortization, and adjusted EBITDA represents EBITDA before items that we do not consider representative of our ongoing operating performance, as identified in the GAAP reconciliation in the accompanying financial data. See also “Non-GAAP Financial Measures.”
Pro forma net income is neither required by, nor presented in accordance with, GAAP. Pro forma net income represents net income adjusted for (i) costs (or gains) related to loss (or gains) on disposal of assets or assets held for sale and asset impairment and closed store costs, (ii) amortization expense and other estimate adjustments (whether expense or income) incurred on the Tax Receivable Agreement (“TRA”) completed at the time of our IPO, (iii) legal costs associated with securities class action litigation, (iv) extraordinary legal settlement costs, (v) insurance proceeds received related to
