DEVON ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued) Proved Undeveloped Reserves The following table presents the changes in Devon’s total proved undeveloped reserves during 2014 (in MMBoe).
## Table 0 ##
At December 31, 2014, Devon had 689 MMBoe of proved undeveloped reserves.
This represents a 2 percent decrease as compared to 2013 and represents 25 percent of total proved reserves.
Drilling and development activities increased Devon’s proved undeveloped reserves 161 MMBoe and resulted in the conversion of 89 MMBoe, or 13 percent, of the 2013 proved undeveloped reserves to proved developed reserves.
Costs incurred related to the development and conversion of Devon’s proved undeveloped reserves were approximately $1.0 billion for 2014.
Additionally, revisions other than price decreased Devon’s proved undeveloped reserves 43 MMBoe primarily due to evaluations of certain U. S.  onshore dry-gas areas, which Devon does not expect to develop in the next five years.
The largest revisions, which were approximately 69 MMBoe, relate to the dry-gas areas in the Barnett Shale in north Texas.
A significant amount of Devon’s proved undeveloped reserves at the end of 2014 related to its Jackfish operations.
At December 31, 2014 and 2013, Devon’s Jackfish proved undeveloped reserves were 384 MMBoe and 441 MMBoe, respectively.
Development schedules for the Jackfish reserves are primarily controlled by the need to keep the processing plants at their 35,000 barrel daily facility capacity.
Processing plant capacity is controlled by factors such as total steam processing capacity and steam-oil ratios.
Furthermore, development of these projects involves the up-front construction of steam injection/distribution and bitumen processing facilities.
Due to the large up-front capital investments and large reserves required to provide economic returns, the project conditions meet the specific circumstances requiring a period greater than 5 years for conversion to developed reserves.
As a result, these reserves are classified as proved undeveloped for more than five years.
Currently, the development schedule for these reserves extends though the year 2031.
Price Revisions 2014 – Reserves increased 9 MMBoe primarily due to higher gas prices in the Barnett Shale and the Anadarko Basin, partially offset by higher bitumen prices, which result in lower after-royalty volumes, in Canada.2013 – Reserves increased 94 MMBoe primarily due to higher gas prices.
Of this increase, 43 MMBoe related to the Barnett Shale and 19 MMBoe related to the Rocky Mountain area.2012 – Reserves decreased 171 MMBoe primarily due to lower gas prices.
Of this decrease, 100 MMBoe related to the Barnett Shale and 25 MMBoe related to the Rocky Mountain area.
## Table 1 ##
The following table presents the carrying value of the plan assets, including major security type for equity and debt securities, which are measured at fair value as of December 31, 2016
## Table 2 ##
The following is a description of the valuation methodologies used for each major category of plan assets measured at fair value.
Information about the valuation hierarchy levels used to measure fair value is detailed in Note 2, “Fair Value of Assets and Liabilities.
” Cash and cash equivalents Cash equivalents include cash in the bank and cash investments in money market funds.
Cash investments in money market funds are valued under the market approach through the use of quoted market prices in an active market, which is the net asset value of the underlying funds, and are classified within level 1 of the valuation hierarchy.
Fund investments These plan assets are primarily invested in affiliated funds and are classified within level 1 of the valuation hierarchy.
They are  y valued at the net asset value of shares held by the plan at year end.
Equity securities, corporate debt securities and other investments These plan assets are classified within level 1 of the valuation hierarchy and are valued at the closing price reported on the active market on which the individual securities are traded.
Government debt securities Government debt securities that have a readily available market price are classified within level 1 of the valuation hierarchy.
These securities are valued at the closing price reported on the active market on which the individual securities are traded.
Government debt securities that include index-linked bonds are classified within level 2 of the valuation hierarchy.
Prices for these bonds are calculated using the relevant index ratio.
Guaranteed investment contracts These plan assets are classified within level 3 of the valuation hierarchy and are valued through use of unobservable inputs by discounting the related cash flows based on current yields of similar instruments with comparable durations considering the credit- worthiness of the issuer.
Guaranteed investment contracts balance at December 31, 2017 is $13.4 million compared to $10.4 million at December 31, 2016
therefore the deferred tax liabilities recognized under U. S.  GAAP are not expected to be used either through a credit in the Consolidated Statements of Income or through settlement of tax obligations.
h.  The results of the discontinued operations of Atlantic Trust have been excluded in arriving at adjusted net income attributable to Invesco Ltd. , which is the basis of calculating adjusted diluted EPS.
Accordingly, the company's nonGAAP financial measures reflect only the continuing business of Invesco.
(5) Market movement on deferred compensation plan liabilities Certain deferred compensation plan awards are linked to the appreciation (depreciation) of specified investments, typically managed by the company.
Invesco hedges economically the exposure to market movements by holding these investments on its balance sheet and through a total return swap financial instrument.
U. S.  GAAP requires the appreciation (depreciation) in the compensation liability to be expensed over the award vesting period in proportion to the vested amount of the award as part of compensation expense.
The full value of the investment and financial instrument appreciation (depreciation) are immediately recorded below operating income in other gains and losses.
This creates a timing difference between the recognition of the compensation expense and the investment gain or loss impacting net income attributable to Invesco Ltd.  and diluted EPS which will reverse over the life of the award and net to zero at the end of the multi-year vesting period.
During periods of high market volatility these timing differences impact compensation expense, operating income and operating margin in a manner which, over the life of the award, will ultimately be offset by gains and losses recorded below operating income on the Consolidated Statements of Income.
The non-GAAP measures exclude the mismatch created by differing U. S.  GAAP treatments of the market movement on the liability and the investments.
Since these plans are hedged economically, management believes it is useful to reflect the offset ultimately achieved from hedging the investment market exposure in the calculation of adjusted operating income (and by calculation, adjusted operating margin) and adjusted net income (and by calculation, adjusted diluted EPS), to produce results that will be more comparable period to period.
The related fund shares will have been purchased on or around the date of grant, eliminating any ultimate cash impact from market movements that occur over the vesting period.
Additionally, dividend income from investments held to hedge economically deferred compensation plans is recorded as dividend income and as compensation expense on the company’s Consolidated Statements of Income on the record dates.
This dividend income is passed through to the employee participants in the plan and is not retained by the company.
The non-GAAP measures exclude this dividend income and related compensation expense.
