Application of new accounting guidance

Application of new accounting guidance

As of January 1, 2015, Umpqua adopted the Financial Accounting Standards Board's ("FASB") Accounting Standard Update ("ASU") No. 2014-01, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. Application of ASU No. 2014-01 provides for a consistent accounting method for our investments in qualified affordable housing projects using a proportional amortization method. As required by ASU No. 2014-01, the new accounting methodology has been retrospectively applied resulting in changes to other non-interest income, tax expense, and net income, deferred tax asset, other assets, and retained earnings in the prior periods presented. The effect of this change was a decrease in net income of $110,000 and $330,000 for the three and nine months ended September 30, 2015, respectively. The effect of this change on the revised September 30, 2014 income statements was a decrease in net income of $107,000 for the three months ended September 30, 2014 and an increase of $102,000 for the nine months ended September 30, 2014. Retained earnings as of January 1, 2014, has been adjusted down by $3.5 million for the effect of the retroactive application of the new standard.

As of January 1, 2015, Umpqua applied FASB ASU No. 2014-04, Receivables -Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. ASU 2014-04 clarifies when a repossession or foreclosure has occurred. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction.

Derivatives

Derivatives 

The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments, residential mortgage loans held for sale, and residential mortgage servicing rights. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy.
