 A commitment discount is a billing discount model that offers reduced rates on preselected SKUs in exchange for an obligated usage or spend amount over a predefined term. Commitment discounts typically consist of a set of purchase and usage records within cost and usage datasets.
 
-Usage-based commitment discounts obligate a customer to a predetermined amount of usage over a preselected term, typically measured in "Hours". In some cases, usage-based commitment discounts allow similar resources of different size classifications to relatively benefit from commitment discount rates. This is typically known as "commitment flexibility", and can be derived by multiplying the number of actual hours consumed by a resource by its predetermined *normalization factor* or *ratio* to derive the number of normalized hours consumed.

In some cases, usage-based commitment discounts allow similar resources of different size classifications to relatively benefit from commitment discount rates. This is typically known as *commitment flexibility*, and can be derived by multiplying the number of actual resource hours consumed by a predefined SKU-based coefficient, sometimes referred to as a *normalization factor* or *ratio*, to derive the number of normalized hours consumed.
 
 Spend-based commitment discounts obligate a customer to a predetermined amount of spend over a preselected term, typically denoted by the invoice's selected billing currency (ex: "USD").
 
 ## Purchasing
 
-While customers are bound to the term of a commitment discount, cloud-service providers, or CSPs, offer various payment options before and/or during the term:
+While customers are bound to the term of a commitment discount, cloud-service providers offer some or all of the following payment options before and/or during the term:
 
 * *Upfront* - The commitment discount is paid in full before the term begins.
 * *Recurring* - The commitment discount is paid on a repeated basis, typically over each billing period of the term.
 * *Partial* - Some of the commitment discount is paid before the term begins, and the rest is paid repeatedly over the term.
 
-For example, if a customer buys a spend-based commitment discount for 1 year, with a $1.00 hourly commitment, and pays with the partial option, the commitment discount's payment consists of both:
+For example, if a customer buys a 1-year, spend-based commitment discount with a $1.00 hourly commit and pays with the partial option, the commitment discount's payment consists of 1 upfront purchase in the beginning of the term *and* monthly recurring purchases with the following totals:
 
 1. *Upfront* - $4,380 (`24 hours * 365 days * $1.00 * 0.5`)
 2. *Recurring* - $182.50 (`24 hours * 365 days * $1.00 / 12 months`)
 
 ## Usage
 
-Commitment discounts follow a "use-it-or-lose-it" model where the amortization of a commitment discount's purchase applies evenly over each charge period of eligible resources over the term.
+Commitment discounts follow a "use-it-or-lose-it" model where the amortization of a commitment discount's purchase applies evenly to eligible resources over each charge period of the term.
 
-For example, if a customer buys a spend-based commitment with a $1.00 hourly commitment in January (31 days), only $1.00 is eligible for consumption for each hourly charge period.  This means that if a customer has eligible resources running during this charge period, some or all of the $1.00 that is allocated to the charge period will also be allocated to some or all of these resources.  Conversely, if a customer does not have eligible resources running during this charge period, the $1.00 allocated to the charge period is wasted.
+For example, if a customer buys a spend-based commitment with a $1.00 hourly commitment in January (31 days), only $1.00 is eligible for consumption for each hourly charge period. If a customer has eligible resources running during this charge period, an amount of up to $1.00 will be allocated to these resources. Conversely, if a customer does have eligible resources running that fully take advantage of this $1.00 during this charge period, then some or all of this amount will go to waste.

 ### Purchase Rows
 
-All commitment discount purchases appear with a positive `BilledCost`, `PricingCategory` as "Committed", and the commitment discount's id populating both the `ResourceId` and `CommitmentDiscountId` value. Upfront purchases appear as a single record also with `ChargeCategory` as "Purchase", `ChargeFrequency` as "One-Time", and the total quantity and units for commitment discount's term as `CommitmentDiscountQuantity` and `CommitmentDiscountUnit`, respectively.

Upfront purchases appear as a single record with `ChargeCategory` as "Purchase", `ChargeFrequency` as "One-Time", and the total quantity and units for commitment discount's term reflected as `CommitmentDiscountQuantity` and `CommitmentDiscountUnit`, respectively.
 
 Recurring purchases are allocated across all corresponding charge periods of the term when `ChargeCategory` is "Purchase", `ChargeFrequency` is "Recurring", and `CommitmentDiscountQuantity` and `CommitmentDiscountUnit` are reflected only for that charge period.
