Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries. In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change.

The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for all of 2023. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission.
Loans Receivable and Allowance for Credit Losses	Loans Receivable and Allowance for Credit LossesThe impact of utilizing the current expected credit loss ("CECL") methodology approach to calculate the allowance for credit losses on loans is significantly influenced by the composition, characteristics and quality of the Company’s loan portfolio, as well as the prevailing economic conditions and forecast utilized. Material changes to these and other relevant factors may result in greater volatility to the allowance for credit losses, and therefore, greater volatility to the Company’s reported earnings. For the three and six months ended June 30, 2023, a worsened economic forecast and related deterioration in the projected commercial property price indices over the expected life of the loan portfolio within our CECL model led to increases to the provisions for credit losses and off-balance sheet credit exposures.

Goodwill	GoodwillGoodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. In accordance with GAAP, goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. Goodwill is analyzed for impairment once a year. As permitted by GAAP, the Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its most recent annual goodwill impairment test as of July 1, 2023. At June 30, 2023, the Company performed an interim goodwill impairment analysis and concluded that no triggering considerations were met and therefore a test for impairment between annual tests was not required.

Basis of Financial Statement Presentation

The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries.

In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change.

The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for all of 2023.

Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission.
