Financial Liabilities

Our debt is recorded at carrying value in our consolidated balance sheets. The carrying value of our senior notes debt outstanding, net of unamortized debt issuance costs, was $6,060 million at December 31, 2020 and $5,366 million at December 31, 2019. The fair value of our senior note debt was $7,352 million at December 31, 2020 and $5,916 million at December 31, 2019. The fair value of our senior note debt is determined based on Level 2 inputs, including quoted market prices for the same or similar debt, or if no quoted market prices are available, on the current prices estimated to be available to us for debt with similar terms and remaining maturities.

Due to the short-term nature, carrying value approximates fair value for commercial paper borrowings. The commercial paper borrowings were $600 million and $300 million at December 31, 2020 and December 31, 2019, respectively.

Put and Call Options Measured at Fair Value

The put and call options associated with our investment in Kindred at Home, which are exercisable at a fixed EBITDA multiple and provide a minimum return on the Sponsor's investment if exercised, are measured at fair value each period using a Monte Carlo simulation. The put and call options fair values, derived from the Monte Carlo simulation, were $45 million and $503 million, respectively, at December 31, 2020 and $28 million and $557 million, respectively, at December 31, 2019.

The significant unobservable inputs utilized in these Level 3 fair value measurements (and selected values) include the enterprise value of Kindred at Home, annualized volatility and secured credit rate. Enterprise value was derived from a discounted cash flow model, which utilized significant unobservable inputs for long-term net operating profit after tax margin, or NOPAT, to measure underlying cash flows, weighted average cost of capital and long term growth rate. The table below presents the assumptions used for each reporting period.


	December 31, 2020		December 31, 2019
Annualized volatility	29.9	%	19.8	%
Secured credit rate	0.4	%	2.2	%
NOPAT	12.0	%	12.0	%
Weighted average cost of capital	9.5	%	10.0	%
Long term growth rate	3.0	%	3.0	%

The calculation of NOPAT utilized net income plus after tax interest expense. We regularly evaluate each of the assumptions used in establishing these assets and liabilities. Significant changes in assumptions for weighted average cost of capital, long term growth rates, NOPAT, volatility, credit spreads, risk free rate, and underlying cash flow estimates, could result in significantly lower or higher fair value measurements. A change in one of these assumptions is not necessarily accompanied by a change in another assumption.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

As disclosed in Note 3, we acquired Enclara, MCCI, FPG, and other health and wellness related businesses during 2020, 2019, and 2018. The values of net tangible assets acquired and the resulting goodwill and other intangible assets were recorded at fair value using Level 3 inputs. The majority of the tangible assets acquired and liabilities assumed were recorded at their carrying values as of the respective dates of acquisition, as their carrying values approximated their fair values due to their short-term nature. The fair values of goodwill and other intangible assets acquired in these acquisitions were internally estimated primarily based on the income approach. The income approach estimates fair value based on the present value of the cash flows that the assets are expected to generate in the future. We developed internal estimates for the expected future cash flows and discount rates used in the present value calculations. Other than assets acquired and liabilities assumed in these acquisitions, there were no material assets or liabilities measured at fair value on a nonrecurring basis during 2020, 2019, or 2018.
