Unless otherwise indicated, the Registrants are currently assessing the impacts such guidance may have (which could be material) on their Consolidated Balance Sheets, Consolidated Statements of Operations and Comprehensive Income, Consolidated Statements of Cash Flows and disclosures, as well as the potential to early adopt where applicable. The Registrants have assessed other FASB issuances of new standards which are not listed below given the current expectation that such standards will not significantly impact the Registrants' financial reporting.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Leases (Issued February 2016):</font><font style="font-family:Arial;font-size:10pt;"> Increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The standard is effective January 1, 2019. Early adoption is permitted; however, the Registrants will not early adopt the standard. The issued guidance required a modified retrospective transition approach, which requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented (January 1, 2017). In July 2018, the FASB issued an amendment to the standard giving entities the option to apply the requirements of the standard in the period of adoption (January 1, 2019) with no restatement of prior periods. Exelon will elect this expedient.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">The new guidance requires lessees to recognize both the right-of-use assets and lease liabilities in the balance sheet for most leases, whereas today only finance lease liabilities (referred to as capital leases) are recognized in the balance sheet. In addition, the definition of a lease has been revised which may result in changes to the classification of an arrangement as a lease. Under the new guidance, an arrangement that conveys the right to control the use of an identified asset by obtaining substantially all of its economic benefits and directing how it is used is a lease, whereas the current definition focuses on the ability to control the use of the asset or to obtain its output. Quantitative and qualitative disclosures related to the amount, timing and judgments of an entity’s accounting for leases and the related cash flows are expanded. Disclosure requirements apply to both lessees and lessors, whereas current disclosures relate only to lessees. Significant changes to lease systems, processes and procedures are required to implement the requirements of the new standard. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from current GAAP. Lessor accounting is also largely unchanged.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:29px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">The standard provides a number of transition practical expedients that entities may elect. These include a "package of three" expedients that must be taken together and allow entities to (1) not reassess whether existing contracts contain leases, (2) carryforward the existing lease classification, and (3) not reassess initial direct costs associated with existing leases. The Registrants will elect this practical expedient.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:29px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In January 2018, the FASB issued additional guidance which provides another optional transition practical expedient. This practical expedient allows entities to not evaluate land easements under the new guidance at adoption if they were not previously accounted for as leases. The Registrants will elect this practical expedient.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">The Registrants have assessed the lease standard and are executing a detailed implementation plan in preparation for adoption on January 1, 2019.

Under the new guidance, on initial recognition and at each reporting period, an entity is required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. The standard does not make changes to the existing impairment models for non-financial assets such as fixed assets, intangibles and goodwill. The standard will be effective January 1, 2020 (with early adoption as of January 1, 2019 permitted) and requires a modified retrospective transition approach through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Registrants are currently assessing the impacts of this standard.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:32px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Goodwill Impairment (Issued January 2017):</font><font style="font-family:Arial;font-size:10pt;"> Simplifies the accounting for goodwill impairment by removing Step 2 of the current test, which requires calculation of a hypothetical purchase price allocation. Under the revised guidance, goodwill impairment will be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill (currently Step 1 of the two-step impairment test). Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. Exelon, Generation, ComEd, PHI and DPL have goodwill as of </font><font style="font-family:Arial;font-size:10pt;">September 30, 2018</font><font style="font-family:Arial;font-size:10pt;">. This updated guidance is not currently expected to impact the Registrants’ financial reporting. The standard is effective January 1, 2020, with early adoption permitted, and must be applied on a prospective basis.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Derivatives and Hedging (Issued September 2017): </font><font style="font-family:Arial;font-size:10pt;">Allows more financial and nonfinancial hedging strategies to be eligible for hedge accounting. The amendments are intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. There are also amendments related to effectiveness testing and disclosure requirements. The standard is effective January 1, 2019, with early adoption permitted, and must be applied using a modified retrospective transition approach. Given the de-designation of hedge accounting relationships as of July 1, 2018, this standard is not expected to impact the Registrants' financial reporting as discussed in Note </font><font style="font-family:Arial;font-size:10pt;">10</font><font style="font-family:Arial;font-size:10pt;"> - </font><font style="font-family:Arial;font-size:10pt;">Derivative Financial Instruments</font><font style="font-family:Arial;font-size:10pt;">.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"> </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Cloud Computing Arrangements (Issued August 2018)</font><font style="font-family:Arial;font-size:10pt;">: Aligns the requirements for capitalizing costs incurred to implement a cloud computing arrangement with the internal-use software guidance. As a result, certain implementation costs incurred in a cloud computing arrangement that are currently expensed as incurred will be deferred and amortized over the non-cancellable term of the arrangement plus any reasonably certain renewal periods. The standard is effective January 1, 2020, with early adoption permitted, and can be applied using either a prospective or retrospective transition approach. A retrospective approach requires a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Registrants are currently assessing the impacts of this standard. </font></div><div style="line-height:120%;padding-top:12px;text-align:justify;text-indent:29px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Defined Benefit Plan Disclosures (Issued August 2018): </font><font style="font-family:Arial;font-size:10pt;">Eliminates existing disclosure requirements related to amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit cost over the next year and the effects of a one-percentage-point change in the assumed health care cost trend rates. In addition, new disclosures were added such as the weighted-average interest crediting rates for cash balance plans and an explanation for the reasons for significant gains and losses related to changes in the benefit obligation. The standard is effective January 1, 2021, with early adoption permitted, and must be applied retrospectively. Exelon will early adopt this standard in the fourth quarter 2018.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Fair Value Measurement Disclosures (Issued August 2018)</font><font style="font-family:Arial;font-size:10pt;">: Removes, modifies and adds disclosure requirements for fair value measurements and aims to reduce costs for preparers and improve the usefulness of information for financial statement users. The standard is effective January 1, 2020, with early adoption permitted, and most amendments must be applied retrospectively with the exception of three amendments which must be applied prospectively. In addition, entities are permitted to delay adoption of the additional disclosure requirements until the effective date and early adopt the removal or modified disclosure requirements. The Registrants are currently assessing the impacts of this standard as well as the potential to early adopt.</font></div></div>
