The guidance is currently effective for us on January 1, 2019 using the modified retrospective method, with early adoption permitted. This guidance is consistent with our previous accounting practices and, accordingly, we do not expect any impact from this guidance on our consolidated financial statements.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: "Times New Roman"; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"> In March 2017, the FASB issued new accounting guidance shortening the amortization period of certain callable debt securities held at a premium.

While we are still evaluating the full impact, at this time we do not expect any significant impact from this guidance on our consolidated financial statements.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: "Times New Roman"; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"> In June 2016, the FASB issued new accounting guidance related to accounting for credit losses on financial instruments. The guidance requires that entities recognize an allowance equal to its estimate of lifetime expected credit losses and applies to most debt instruments not measured at fair value, which would primarily include our commercial mortgage loans and reinsurance receivables. The new guidance retains most of the existing impairment guidance for <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">available-for-sale</font></font> debt securities but amends the presentation of credit losses to be presented as an allowance as opposed to a write-down and permits the reversal of credit losses when reassessing changes in the credit losses each reporting period. The new guidance is effective for us on January 1, 2020, with early adoption permitted beginning January 1, 2019. Upon adoption, the modified retrospective method will be used and a cumulative effect adjustment in retained earnings as of the beginning of the year of adoption will be recorded. We are in process of evaluating the impact the guidance may have on our consolidated financial statements.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: "Times New Roman"; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"> In February 2016, the FASB issued new accounting guidance related to the accounting for leases. The new guidance generally requires lessees to recognize both a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-to-use</font></font> asset and a corresponding liability on the balance sheet. The guidance is effective for us on January 1, 2019, with early adoption permitted. A modified retrospective transition approach is required as of the earliest period presented. Amendments to the guidance also allow an optional transition method practical expedient, which permits entities to apply the new lease standard using the modified retrospective transition approach at the date of adoption. Certain other practical expedients are available, which we are in the process of evaluating. We have identified our significant leases by asset type that will be impacted by the new guidance and begun implementation of a new software platform to facilitate compliance with the new guidance. Upon adoption, we expect to apply the optional transition method and record a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-of-use</font></font> asset and liability on our balance sheet related to existing operating leases. While we are still evaluating the full impact, at this time we do not expect a significant impact from this guidance on our consolidated financial statements and we are in process of evaluating the impact to our disclosures.</p> </div>
