Prepaid agreements not-to-compete are amortized over the term of the respective agreements, ranging generally from one to ten years. Amortization expense was approximately $140,000 and $69,000 for the three months ended March 31, 2014 and 2015, respectively. Deferred loan costs are being amortized over the term of the related debt using the effective interest method. Debt issuance costs related to our convertible subordinated notes are being amortized using the effective interest method over the seven-year term of the notes. See Note 13 to the Consolidated Financial Statements herein for further discussion related to our convertible subordinated notes. Our tradenames have indefinite lives and therefore are not amortized. During the three months ended March 31, 2015, we increased tradenames by approximately $1.2 million related to our acquisition of a funeral home business in February 2015.
