Summary of Expected Impact of Recently Announced Accounting Pronouncements

Standard	Issue Date	Description	Effective Date	Expected Financial Statement Impact
Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	Q2 2016	ASU 2016-13 ("the Standard") represents a significant change to the incurred loss model currently used to account for credit losses. The Standard requires an entity to estimate the credit losses expected over the life of the credit exposure upon initial recognition of that exposure. The expected credit losses consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. Exposures with similar risk characteristics are required to be grouped together when estimating expected credit losses. The initial estimate and subsequent changes to the estimated credit losses are required to be reported in current earnings in the income statement and through an allowance in the balance sheet. ASU 2016-13 is applicable to financial assets subject to credit losses and measured at amortized cost and certain off-balance-sheet credit exposures. The Standard will modify the way the Company estimates its allowance for risk-sharing obligations and its allowance for loan losses. ASU 2016-13 requires modified retrospective application to all outstanding, in-scope instruments, with a cumulative-effect adjustment recorded to opening retained earnings as of the beginning of the period of adoption.	January 1, 2020 (early adoption permitted January 1, 2019)	The Company is in the preliminary stages of implementation as it is still in the process of determining the significance of the impact the Standard will have on its financial statements and the timing of when it will adopt ASU 2016-13. The Company expects its Allowance for risk-sharing obligations and allowance for loan losses to increase when ASU 2016-13 is adopted.
ASU 2016-02, Leases (Topic 842)	Q1 2016	ASU 2016-02 represents a significant reform to the accounting for leases. Lessees initially recognize a lease liability for the obligation to make lease payments and a right-of-use (“ROU”) asset for the right to use the underlying asset for the lease term. The lease liability is measured at the present value of the lease payments over the lease term. The ROU asset is measured at the lease liability amount, adjusted for lease prepayments, lease incentives received and the lessee’s initial direct costs. Lessees generally recognize lease expense for these leases on a straight-line basis, which is similar to what they do today. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements.	January 1, 2019 (early adoption is permitted)	The Company is in the preliminary stages of implementation as it is still in the process of determining the significance of the impact ASU 2016-02 will have on its financial statements and the timing of when it will adopt ASU 2016-02.
ASU 2016-01, Financial Instruments – Overall – Recognition and Measurement of Financial Assets and Financial Liabilities	Q1 2016	The guidance requires that unconsolidated equity investments not accounted for under the equity method be recorded at fair value, with changes in fair value recorded through net income. The accounting principles that permitted available-for-sale classification with unrealized holding gains and losses recorded in other comprehensive income for equity securities will no longer be applicable. The guidance is not applicable to debt securities and loans and requires minor changes to the disclosure and presentation of financial instruments. ASU 2016-01 generally requires a cumulative-effect adjustment to opening retained earnings as of the beginning of the period of adoption.	January 1, 2018 (early adoption permitted for certain parts)	The Company does not believe that ASU 2016-01 will have a material impact on its reported financial results.
ASU 2014-09, Revenue from Contracts with Customers (Topic 606)	Q2 2014	ASU 2014-09 represents a comprehensive reform of many of the revenue recognition requirements in GAAP. The guidance in the ASU supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and supersedes or amends much of the industry-specific revenue recognition guidance found throughout the Accounting Standards Codification. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The ASU creates a five-step process for achieving the core principle: 1) identifying the contract with the customer, 2) identifying the performance obligations in the contract, 3) determining the transaction price, 4) allocating the transaction price to the performance obligations, and 5) recognizing revenue when an entity has completed the performance obligations. The ASU also requires additional disclosures that allow users of the financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows resulting from contracts with customers. The guidance permits the use of the full retrospective or modified retrospective transition methods.	January 1, 2018 (early adoption permitted January 1, 2017)	The Company completed its analysis of ASU 2014-09 and concluded that it will not have a material impact on the amount or timing of revenue the Company records under its current revenue recognition practices. Additionally, the Company believes that this ASU will not impact the presentation of the Company's financial statements or require significant additional footnote disclosures.
