Changes in Accounting Principles and Effects of New Accounting Pronouncements

Standard/Adoption Date	Description	Effects on the Financial Statements
Standards Adopted During the Current Year
Leases Jan 1, 2019	Requires lessees to recognize assets and liabilities related to certain operating leases on the balance sheet, requires additional disclosures by lessees, and contains targeted changes to accounting by lessors.	BB&T established ROU assets of $860 million and lease liabilities of $997 million. The net impact to equity was a reduction of $40 million. There was no material impact to its Consolidated Statements of Income. BB&T adopted the guidance on a prospective basis and did not reassess whether any expired or existing contract contains a lease, the classification of leases or the initial direct costs.
Standards Not Yet Adopted
Credit Losses Jan 1, 2020	Replaces the incurred loss impairment methodology with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit deteriorated loans will receive an allowance for expected credit losses. Any credit impairment on AFS debt securities for which the fair value is less than cost will be recorded through an allowance for expected credit losses. The standard also requires expanded disclosures related to credit losses and asset quality.	BB&T expects that the ACL could be materially higher; however, the magnitude of the increase, which is highly dependent on existing and forecasted economic conditions at the time of adoption, has not yet been quantified. BB&T performed limited parallel testing in the second quarter of 2019, and is currently conducting a more comprehensive parallel testing program that will include consideration of qualitative adjustments that among other things will include adjustments designed to capture an estimate for the inherent uncertainty related to forecasts of future economic conditions. In light of the anticipated merger with SunTrust, BB&T is also evaluating the impact of the merger on its CECL implementation project to ensure that its consolidated CECL estimate gives appropriate consideration to the acquired SunTrust loan portfolio.
