Topic	Description of Guidance	Effective Date	Status of Company's Evaluation
Revenue Recognition (ASU 2014-09, as amended)	Requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. Applied either retrospectively or as a cumulative effect adjustment as of the adoption date.	January 1, 2018	The Company is continuing to evaluate the impact this ASU will have on its consolidated financial statements and disclosures. The Company completed an initial impact assessment and believes adopting this ASU will materially impact the timing of revenue recognition, primarily for implant product sales to stocking distributors, which are currently accounted for using the sell-through method. Specifically, the Company believes the revenue associated with these sales will be recorded at the time of the sale instead of deferring recognition until cash is received. The Company expects to adopt this new guidance using the modified retrospective transition method.
Financial Instruments (ASU 2016-01)	Requires entities to measure equity investments, except in limited circumstances, at fair value and recognize any changes in fair value in net income. Applied prospectively.	January 1, 2018	The Company is currently evaluating the impact this ASU may have on its consolidated financial statements.
Leases (ASU 2016-02)	Requires a lessee to recognize lease assets and lease liabilities for leases classified as operating leases. Applied using a modified retrospective approach.	January 1, 2019	The Company is currently evaluating the impact this ASU may have on its consolidated financial statements; however, the Company expects this guidance will result in current operating lease obligations being reflected on the consolidated balance sheet.
Income Taxes (ASU 2016-16)	Reduces complexity by requiring current and deferred income taxes for intra-entity asset transfers, other than inventory, to be recognized when the transfer occurs. Applied using a modified retrospective approach.	January 1, 2018	The Company is currently evaluating the impact this ASU may have on its consolidated financial statements.
Statement of Cash Flows (ASU 2016-18)	Reduces diversity in classification and presentation of restricted cash, including transfers between cash and restricted cash, on the statement of cash flows. Applied retrospectively.	January 1, 2018	The Company is currently evaluating the impact this ASU may have on its consolidated statement of cash flows.
