adjusts the earnings from the consumer loan investment to a level yield basis. Core earnings is used by management to evaluate our performance without taking into account: (i) realized and unrealized gains and losses, which although they represent a part of our recurring operations, are subject to significant variability and are generally limited to a potential indicator of future economic performance; (ii) incentive compensation paid to our Manager; (iii) non-capitalized transaction-related expenses; and (iv) deferred taxes, which are not representative of current operations.
Our definition of core earnings includes accretion on held-for-sale loans as if they continued to be held-for-investment. Although we intend to sell such loans, there is no guarantee that such loans will be sold or that they will be sold within any expected timeframe. During the period prior to sale, we continue to receive cash flows from such loans and believe that it is appropriate to record a yield thereon. In addition, our definition of core earnings excludes all deferred taxes, rather than just deferred taxes related to unrealized gains or losses, because we believe deferred taxes are not representative of current operations. Our definition of core earnings also limits accreted interest income on RMBS where we receive par upon the exercise of associated call rights based on the estimated value of the underlying collateral, net of related costs including advances. We created this limit in order to be able to accrete to the lower of par or the net value of the underlying collateral, in instances where the net value of the underlying collateral is lower than par. We believe this amount represents the amount of accretion we would have expected to earn on such bonds had the call rights not been exercised.
Beginning January 1, 2020, our investments in consumer loans are accounted for under the fair value option. Core earnings adjusts earnings on consumer loans to a level yield to present income recognition across the consumer loan portfolio in the manner in which it is economically earned, to avoid potential delays in loss recognition, and align it with our overall portfolio of mortgage-related assets which generally record income on a level yield basis. With respect to consumer loans classified as held-for-sale, the level yield is computed through the expected sale date. With respect to the gains recorded under GAAP in 2014 and 2016 as a result of a refinancing of, and the consolidation of, the debt related to our investments in consumer loans, and the consolidation of entities that own our investments in consumer loans, respectively, we continue to record a level yield on those assets based on their original purchase price.
While incentive compensation paid to our Manager may be a material operating expense, we exclude it from core earnings because (i) from time to time, a component of the computation of this expense will relate to items (such as gains or losses) that are excluded from core earnings, and (ii) it is impractical to determine the portion of the expense related to core earnings and non-core earnings, and the type of earnings (loss) that created an excess (deficit) above or below, as applicable, the incentive compensation threshold. To illustrate why it is impractical to determine the portion of incentive compensation expense that should be allocated to core earnings, we note that, as an example, in a given period, we may have core earnings in excess of the incentive compensation threshold but incur losses (which are excluded from core earnings) that reduce total earnings below the incentive compensation threshold. In such case, we would either need to (a) allocate zero incentive compensation expense to core earnings, even though core earnings exceeded the incentive compensation threshold, or (b) assign a “pro forma” amount of incentive compensation expense to core earnings, even though no incentive compensation was actually incurred. We believe that neither of these allocation methodologies achieves a logical result. Accordingly, the exclusion of incentive compensation facilitates comparability between periods and avoids the distortion to our non-GAAP operating measure that would result from the inclusion of incentive compensation that relates to non-core earnings.
With regard to non-capitalized transaction-related expenses, management does not view these costs as part of our core operations, as they are considered by management to be similar to realized losses incurred at acquisition. Non-capitalized transaction-related expenses are generally legal and valuation service costs, as well as other professional service fees, incurred when we acquire certain investments, as well as costs associated with the acquisition and integration of acquired businesses.
Since the third quarter of 2018, as a result of the Shellpoint Partners LLC (“Shellpoint”) acquisition, we, through our wholly owned subsidiary, NewRez, originate conventional, government-insured and nonconforming residential mortgage loans for sale and securitization. In connection with the transfer of loans to the Government-sponsored enterprises (“GSEs”) or mortgage investors, we report realized gains or losses on the sale of originated residential mortgage loans and retention of mortgage servicing rights, which we believe is an indicator of performance for our servicing and origination segments and therefore included in core earnings. Realized gains or losses on the sale of originated residential mortgage loans had no impact on core earnings in any prior period, but may impact core earnings in future periods.
Beginning with the third quarter of 2019, as a result of the continued evaluation of how Shellpoint operates its business and its impact on our operating performance, core earnings includes Shellpoint’s GAAP net income with the exception of the unrealized gains or losses due to changes in valuation inputs and assumptions on MSRs owned by NewRez, and non-capitalized transaction-related expenses. This change was not material to core earnings for the quarter ended September 30, 2019.
Management believes that the adjustments to compute “core earnings” specified above allow investors and analysts to readily identify and track the operating performance of the assets that form the core of our activity, assist in comparing the core operating results between periods, and enable investors to evaluate our current core performance using the same measure that management uses to operate the business. Management also utilizes core earnings as a measure in its decision-making process relating to improvements to the underlying fundamental operations of our investments, as well as the allocation of resources between those investments, and management also relies on core earnings as an indicator of the results of such decisions. Core earnings excludes certain recurring items, such as gains and losses (including impairment and reserves, as well as derivative activities) and non-capitalized transaction-related expenses, because they are not considered by management to be part of our core operations for the reasons described herein. As such, core earnings is not intended to reflect all of our activity and should be considered as only one of the factors used by management in assessing our performance, along with GAAP net income which is inclusive of all of our activities.
The primary differences between core earnings and the measure we use to calculate incentive compensation relate to (i) realized gains and losses (including impairments and reserves for expected credit losses), (ii) non-capitalized transaction-related expenses and (iii) deferred taxes (other than those related to unrealized gains and losses). Each are excluded from core earnings and included in our incentive compensation measure (either immediately or through amortization). In addition, our incentive compensation measure does not include accretion on held-for-sale loans and the timing of recognition of income from consumer loans is different. Unlike core earnings, our incentive compensation measure is intended to reflect all realized results of operations.
